Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of contractile banister, including gate barrier box
1, the right of gate barrier box 1 offers gate barrier box space 2, and the inclined upward in gate barrier box space 2 is arranged symmetrically, and there are two recessed
Slot 3 is fixed with shaft 4 in groove 3, and idler wheel 5 is fixed in shaft 4, and fitting is provided with swivel becket 6, swivel becket between idler wheel 5
6 insides are fixedly welded with several tube bodies 7, and the first contraction pole 8 is equipped in tube body 7, is equipped with the second contraction pole in the first contraction pole 8
9, lateral cylindrical groove 10 is offered inside 1 upper left side of gate barrier box, 1 upper interior of gate barrier box offers vertical cylindrical groove 11,
Latch post 12 is equipped in vertical cylindrical groove 11.
Further, shaft 4 and idler wheel 5 are equipped with two pairs, and two pairs of shafts 4 and idler wheel 5 are about in swivel becket 6
Heart line is symmetrical.
Further, tube body 7, the first contraction pole 8 and the second contraction pole 9 are equipped with three pairs altogether and specification is consistent, and tube body
7,9 Triangular array branch of the first contraction pole 8 and the second contraction pole.
Further, lateral cylindrical groove 10 is mutually perpendicular to vertical cylindrical groove 11, and laterally cylindrical groove 10 and banister case
1 upper surface of body is parallel.
Further, one end of shaft 4 can be rotated hinged with 3 inner wall of groove, and the other end of shaft 4 and idler wheel 5 are solid
Fixed welding, shaft 4 is set to the medium position of groove 3, and the inner sidewall fixation of groove 3 is embedded with bearing, the inner ring of bearing
It is fixedly welded with the end portion of shaft 4.
Further, the diameter of vertical cylindrical groove 11 is three millimeters bigger than the diameter of latch post 12, and latch post 12 is vertical
