Abstract
The invention discloses a threaded stud structure of a plastic part, which comprises a plastic part, a first part and a second part, wherein the inside surface of the plastic part is provided with a concave meat-stealing area, a threaded stud is arranged in the meat-stealing area, a nut is arranged in the threaded stud and the periphery of the bottom part of the threaded stud is provided with a plurality of ribs; the first part is provided with a through hole through which the first part is sleeved on the threaded stud, the end, provided with the nut, of the threaded stud is exposed after the stud passes through the through hole, and the ribs arranged on the periphery of the threaded stud are pressed against the face, on which the through hole is arranged, of the first part respectively; and the inside surface of the second part is provided with a through hole post which is jointed with the threaded stud. The ribs arranged on the periphery of the threaded stud are pressed against the face, on which the through hole is arranged, so when a screw is to be locked, the screw passes through the through hole post to be screwed into the nut on the threaded stud and the first part and the ribs are main stressed points. Thus, the phenomenon that a dent is produced on the surface of the plastic part as the threaded stud is pulled to sink is eliminated.
Description
[technical field]
The present invention is meant a kind of threaded stud structure of plastic parts especially about a kind of threaded stud structure.
[background technique]
In the electronic product through regular meeting design threaded stud structure with as the connection between the component, and designed threaded stud structure on some plastic parts, its internal surface is corresponding be provided with this screw column around just have a depression steal the meat district.
Please consult Fig. 1, Fig. 2 jointly, it illustrates the decomposing schematic representation into the threaded stud structure of the plastic parts of the assembling schematic representation of the plastic parts threaded stud structure of prior art, prior art respectively.
The threaded stud structure of this plastic parts comprises: a plastic parts 1, its internal surface are provided with the meat district 2 steathily of a depression, should steal meat district 2 and be provided with a screw column 3, are provided with nut 4 in this screw column 3; One first parts 5 which is provided with a through hole 6, and these first parts 5 are sheathed on the above-mentioned screw column 3 by this through hole 6, and above-mentioned screw column 3 is passed this through hole 6 and exposed the end that it establishes nut 4; One second parts 7, its internal surface are provided with a through hole post 8, and this through hole post 8 docks with above-mentioned screw column 3, and this through hole post 8 penetrates this second parts 7.
Utilize the threaded stud structure of above-mentioned plastic parts; because mould manufacturing and moulding tolerance; size is difficult to accomplish and design striking resemblances; often have small gap between the junction surface of screw column 3 and through hole post 8; again since screw column 3 hot melt nuts 4 rear thread posts 3 surfaces through problems such as the biased hearts of regular meeting's out-of-flatness and screw column 3 holes; screw column 3 often takes place when lock screw 9 drawn the sunken situation that plastic parts 1 appearance produces indenture that takes place, especially some thin wall plasticses are easy to take place this problem.
In view of this, be necessary to provide a kind of threaded stud structure of plastic parts in fact, utilize the threaded stud structure of this plastic parts, screw column 3 can not take place when lock screw 9 drawn the situation that plastic parts 1 appearance produces indenture that takes place that falls into.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of threaded stud structure of plastic parts, utilize the threaded stud structure of this plastic parts, screw column can not take place when the lock screw drawn the situation that the plastic parts appearance produces indenture that takes place that falls into.
For reaching above-mentioned purpose, the threaded stud structure of plastic parts of the present invention, this structure comprises:
One plastic parts, its internal surface is provided with a screw column, is provided with nut in this screw column, and this screw column bottom is provided with several ribs all around;
One first parts, which is provided with a through hole, these first parts are sheathed on the above-mentioned screw column by this through hole, and above-mentioned screw column is passed this through hole and exposed the end that screw column is established nut, and respectively this rib that is provided with around the above-mentioned screw column offsets with the face that these first parts are provided with through hole respectively;
One second parts, its internal surface are provided with a through hole post, and this through hole post docks with above-mentioned screw column.
Compared to prior art, utilize the threaded stud structure of this plastic parts, offset with the face that these first parts are provided with through hole respectively by respectively this rib that is provided with around the screw column, thereby when the lock screw, screw passes the nut on this through hole post screw-in screw column, between first parts and above-mentioned each rib is main force bearing point, is drawn the situation that the plastic parts appearance produces indenture that takes place that falls into thereby avoid taking place screw column.
For purpose of the present invention, structure characteristics and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the assembling schematic representation into the threaded stud structure of the plastic parts of prior art.
Fig. 2 illustrates the decomposing schematic representation into the threaded stud structure of the plastic parts of prior art.
Fig. 3 illustrates the assembling schematic representation into the threaded stud structure of the plastic parts of a preferred embodiment of the present invention.
Fig. 4 illustrates the decomposing schematic representation into the threaded stud structure of the plastic parts of a preferred embodiment of the present invention.
[embodiment]
Please consult Fig. 3, Fig. 4 jointly, it illustrates the decomposing schematic representation of threaded stud structure of the plastic parts of the assembling schematic representation into the threaded stud structure of the plastic parts of a preferred embodiment of the present invention, a preferred embodiment of the present invention respectively.
In this preferred embodiment, the threaded stud structure of this plastic parts comprises:
One plastic parts 10, its internal surface is provided with the meat district 20 steathily of a depression, should steal meat district 20 and be provided with a screw column 30, be provided with nut 40 in this screw column 30, these screw column 30 bottoms are provided with several ribs 90 all around, rib 90 is four herein, and is equally spaced around screw column 30, thereby reaches stressed effect preferably;
One first parts 50, which is provided with a through hole 60, these first parts 50 are sheathed on the above-mentioned screw column 30 by this through hole 60, above-mentioned screw column 30 is passed this through hole 60 and is exposed the end that screw column 30 is established nut 40, and respectively this rib 90 that is provided with around the above-mentioned screw column 30 offsets with the face that these first parts 50 are provided with through hole 60 respectively;
One second parts 70, its internal surface are provided with a through hole post 80, and this through hole post 80 docks with above-mentioned screw column 30, and this through hole post 80 penetrates this second parts 70.
