Detailed Description
The novel furniture fixing device is characterized by further comprising a stabilizing assembly formed by oppositely clamping an upper buckle and a lower buckle, wherein the bottom surface and the middle of the end part of the lower buckle 6 are respectively and correspondingly provided with a fixing pipe sleeve 7 and a nut fixing sleeve 8 provided with a nut 19, the lower buckle 6 is inserted into an inserting hole 4 in the chassis 1 from the bottom, the shape and the number of the inserting holes 4 are determined by the fixing pipe sleeve 7 and the nut 19 arranged on the nut fixing sleeve 8, an inserting rod 11 inserted into the fixing pipe sleeve 7 is arranged on the bottom surface of the end part of the upper buckle 10, a nut 19 through hole 12 matched with the nut 19 is formed in the middle of the upper buckle 10, a small round hole 9 communicated with the threaded hole of the nut 19 is formed in the position of the center of the nut fixing sleeve 8, a transversely protruding limiting block 14 is arranged at the edge of the end part of the upper buckle 10, a limiting groove 20 matched with the limiting block 14 is formed in the bottom of the pipe wall of the cylindrical vertical pipe 2', and when a threaded rod 3 in the cylindrical vertical pipe 2' is inserted into the nut 19, the limiting groove 20 is clamped into the limiting block 14.
The present embodiment provides a means for securing or otherwise limiting the position of a device for use in connection with securing to furniture, particularly tables. In order to prevent relative rotation between the table top (not shown), the chassis 1, the stand pipe and the top support (not shown) due to poor fixation, a stabilizing assembly consisting of a lower clip 6 and an upper clip 10 is provided, and the chassis 1 is modified to adapt to the stabilizing assembly.
The lower buckle 6 is provided with a protruded fixing pipe sleeve 7 and a nut fixing sleeve 8 at the end part thereof, and the improvement of the chassis 1 is that a plurality of insertion holes 4 are formed on the basis of the original chassis 1, the shape, the purpose and the number of the insertion holes 4 are determined by the structure of the lower buckle 6, specifically, the fixing pipe sleeve 7 and the nut fixing sleeve 8 of the lower buckle 6 are determined by the fixing pipe sleeve 7 and the nut fixing sleeve 8 of the lower buckle 6, the fixing pipe sleeve 7 and the nut fixing sleeve 8 of the lower buckle 6 are inserted into the insertion holes 4 from the bottom of the chassis 1 and are inserted into the chassis 1, and the hexagonal nut 19 is placed on the nut fixing sleeve 8 to complete the installation of the lower buckle 6. In order to exert the function of the hexagonal nut 19, the bottom of the nut fixing sleeve 8 is not sealed, but a small circular hole 9 with a diameter smaller than that of the nut fixing sleeve 8 is formed at the bottom, and the purpose of the small circular hole 9 is to facilitate the threaded rod 3 inserted into the nut 19 to pass through.
The inserted bar 11 is arranged at the end of the upper buckle 10, the inserted bar 11 is also protruded, and the upper buckle 10 is also provided with a nut 19 through hole 12 corresponding to the nut fixing sleeve 8. When the assembly is used, the upper buckle 10 is required to be reversely buckled, and the inserted rod 11 is inserted into the fixed pipe sleeve 7, so that the assembly of the stable assembly is completed. The side wall of the edge of the upper buckle 10 is provided with a laterally protruding limiting block 14 for limiting the rotation of the cylindrical vertical pipe 2'.
The improvement of the cylindrical stand pipe 2' is that a limiting groove 20 is formed in the pipe wall of the bottom of the stand pipe, and when the stand pipe is installed on a base, the limiting groove 20 of the stand pipe is just clamped on a limiting block 14, so that the stand pipe can be prevented from rotating randomly. It should be noted that the present embodiment is a series of improvements made on the basis of the cylindrical riser 2' and the upper buckle 10.
The utility model provides a novel furniture fixing device, including chassis 1, install polygon riser 2 on chassis 1 and the top of setting on the riser holds in the palm, a serial communication port, still including by last, the stabilizing component that lower buckle subtend joint formed, the tip bottom surface of lower buckle 6 and middle nut fixed cover 8 that is provided with fixed pipe box 7 and installs nut 19 that correspond respectively, lower buckle 6 inserts patchhole 4 on chassis 1 from the bottom, the shape and the quantity of patchhole 4 are determined by fixed pipe box 7 and nut 19 of installing on nut fixed cover 8, be provided with on the tip bottom surface of last buckle 15 and insert fixed pipe box 7's inserted bar 16 and go up buckle 15 middle division have with nut 19 complex nut 19 through-hole 17, the little round hole 9 that link up with nut 19 screw hole is seted up to nut fixed cover 8 centre of a circle position, the edge of going up buckle 15 tip 18 with polygon riser 2's corner matched with, tip 18 and polygon riser 2's corner friction fit when the threaded rod in the polygon riser 2 inserts nut 19.
The improvement of this embodiment is to change the cylindrical riser 2' into the polygonal riser 2, and the difference of the upper buckle 15 is that the edge of the end of the upper buckle 15 of this embodiment is provided with a pointed tip 18 instead of the protruding stopper 14. The tip portion 18 is adapted to the polygonal vertical pipe 2, and fig. 20 shows a use state diagram of the tip portion 18, in which an embodiment of a quadrangular vertical pipe, that is, a square vertical pipe is provided, and when the vertical pipe is a square pipe, an included angle between two adjacent sides is 90 degrees, and a tip angle of the corresponding tip portion 18 is also 90 degrees. If the riser is pentagonal or hexagonal, the tip 18 may have a different angle to accommodate the riser.
The above described embodiments provide two different stabilizing assemblies while in embodiments making improvements to the riser and limiting the shape of the riser separately. It should be noted that, in the present invention, the upper buckle 10 with the limiting block 14 does not only use the cylindrical vertical pipe 2', but also uses the square vertical pipe or the polygonal vertical pipe 2 instead to achieve the technical effects described in the embodiments, for example, the opposite pipe walls of the square vertical pipe may also be provided with the limiting groove 20. Meanwhile, the cylindrical vertical pipe 2 'can be adapted by using the upper buckle 15 with the tip part 18, and the technical effect to be achieved in the embodiment can be achieved only by enabling the tip part 18 to be in friction fit with the inner part of the pipe wall of the cylindrical vertical pipe 2'. The two embodiments of the invention thus provide different upper snap fits for which riser and for which improvement the most preferred solution is adopted for the riser, and not the only solution.
Preferably, the radius of the small circular hole 9 is smaller than the radius of the fixing socket 7, and the radius of the small circular hole 9 is equal to the radius of the threaded hole of the nut 19. The small round hole 9 can have a radius larger than the radius of the threaded hole of the nut 19 and smaller than the maximum radius of the nut 19 because of the thickness of the nut 19 itself. However, in order to better secure the threaded rod 3 through the nut 19, the radius of the small circular hole 9 is equal to the radius of the threaded hole, so that the small circular hole 9 can be tightly fitted with the threaded rod 3.
Preferably, the upper buckle and the lower buckle are in a long strip plate shape, and the number of the fixing pipe sleeves 7 and the inserting rods is at least two. In order to reduce the manufacturing cost, upper and lower buckle is rectangular shape and is the platelike, and fixed pipe box 7 is two and distributes under on buckle 6's both ends bottom surface, and the fixed cover 8 of nut sets up the intermediate position at buckle 6 down simultaneously. The corresponding inserted rod of the upper buckle is arranged corresponding to the fixed sleeve 7 of the lower buckle 6. Meanwhile, the insertion hole 4 of the chassis 1 can be adaptively adjusted according to the shapes of the upper buckle 6 and the lower buckle 6.
Preferably, the nut 19 is a flange nut. Because the width of the bottom of the flange nut is larger, the flange nut can be better placed in the nut fixing sleeve 8, and the requirement on the small circular hole 9 is also reduced.
