Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
It should be noted that in the utility model embodiment institute it is directional instruction (such as up, down, left, right, before and after,
Outside, it is interior ...) it is only used for explaining relative position relation under a certain particular pose (as shown in drawings) between each component, movement
Situation etc., if the particular pose changes, directionality instruction also correspondingly changes correspondingly.
A kind of interlocking self-balancing pulley as shown in Figs 1-4, including connecting seat 1, balance shaft 2, lock tube 3, pulley 4 and connects
Extension bar 5, connecting seat 1 have the perforative through-hole in left and right, it is preferable that and the through-hole is cuboid through-hole 111,
The interior surface of the cuboid through-hole 111 has secured adjusted portion 12, and specifically, secured adjusted portion 12 is in semicolumn
Shape is projectedly arranged below upper surface inside cuboid through-hole 111, i.e. semicircle outer surface of column towards inside through-hole, and
The axial direction in the semi-cylindrical secured adjusted portion 12 is mutually perpendicular to cuboid through-hole 111 through direction.Balance shaft 2 is contacted with solid
Determine the lower section of adjustment portion 12, and the annular groove 21 to cooperate with the semi-cylindrical protruded with secured adjusted portion 12, tool
Body, the annular groove 21 is circumferentially disposed in 2 middle part of balance shaft, the radian of the annular groove 21 just with secured adjusted portion 12
Semi-cylindrical outer surface matches, and so, by the cooperation in annular groove 21 and secured adjusted portion 12, has made balance shaft 2 both
It can be moved left and right along the axial direction in secured adjusted portion 12, it also can be around 12 axial rotation of secured adjusted portion.But it is balancing
The opposite side that axis 2 is in contact with through-hole, i.e. 2 lower part of balance shaft are additionally provided with lock tube 3, which can wrap the lower part of balance shaft 2
It wraps, 3 inner surface of lock tube is cylindrical surface 34, and upper part has half opening 32, can be put into balance shaft 2 by the half opening 32
Inside lock tube 3,2 outer surface of balance shaft and the inner surface of lock tube 3 after being put into are bonded to each other.It is in addition, flat in order to further fix
Weigh axis 2, is additionally provided with elastic bumps 33 in the lower part on 3 inner surface cylindrical surface 34 of lock tube, which is linked to be with lock tube 3
One entirety, the other end vacantly protrude from cylindrical surface 34 and form elastic construction, since elastic bumps 33 have elasticity,
After balance shaft 2 is put into lock tube 3, the elastic bumps 33 will be compressed to it is concordant with cylindrical surface 34, under the effect of elasticity, elasticity it is convex
Balance shaft 2 can be withstood upwards by playing 33, and in this case, balance shaft 2 is just locked in the secured adjusted portion 12 on top and the elasticity of lower part
Protrusion 33.On the other hand, the outer shape of lock tube 3 is rectangular-shape, and cuboid through-hole 111 can be inserted into from both sides, and
The outer surface of lock tube 3 and the inner surface of cuboid through-hole 111 contact with each other after insertion, this results in lock tube 3 can not be in cuboid
It is moved left and right in through-hole 111, and since balance shaft 2 is mounted in lock tube 3, balance shaft 2 will be unable to along secured adjusted portion
12 move axially back and forth, thus, the movement of balance shaft 2 be restricted to be only capable of it is certain around 12 axial rotation of secured adjusted portion
Distance.
Preferably, it there are two pulley 4 is set, is respectively symmetrically respectively provided among 2 both ends of balance shaft, pulley 4 and balance shaft 2
Center hole, the center hole can be inserted into connecting rod 5, and pulley 4, balance shaft 2 are fixed up by connecting rod 5 by center hole.
It to sum up states, when connecting seat 1 connects door leaf by threaded hole 13, pulley 4 is in track, makees in the gravity of door leaf
Under, even if track is a bit uneven, balance shaft 2 can be right by the cooperation between annular groove 21 and secured adjusted portion 12
The height of its two head sheave 4 automatically adjusts, and makes the pulley 4 at 2 both ends of balance shaft can be contacted on track well always,
This can just avoid the pulley 4 of 2 one end of balance shaft contact in orbit and the pulley 4 of the other end is in the situation of vacant state
Occur, so as to ensure that the steady and smooth in track of pulley 4 slides.
In addition, in order to further keep balancing, realization is good to slide effect, and the threaded hole 13 at 1 middle part of connecting seat is left
Right both sides respectively symmetrically set cuboid through-hole 11, and are designed with balance shaft 2, lock tube 3 at each cuboid through-hole 11, and
Pulley 4 is also symmetrically disposed in 2 both ends of balance shaft, and equally, pulley 4, balance shaft 2 are fixed by connecting rod 5.
Although hereinbefore the utility model is described by reference to some embodiments, this reality is not being departed from
In the case of with novel range, various improvement can be carried out to it and component therein can be replaced with equivalent.Especially
It is as long as that, there is no structural conflict, the various features in each embodiment disclosed by the utility model can pass through arbitrary side
Formula be combined with each other use, does not carry out the description of exhaustive merely for the sake of province to the situation of these combinations in the present specification
Slightly length and the considerations of economizing on resources.Therefore, the utility model is not limited to specific embodiment disclosed herein, but including
All technical solutions fallen within the scope of the appended claims.
