With generation strong influence.
Utility model content
(1) technical problems to be solved
The purpose of this utility model seeks to overcome disadvantages mentioned above, it is desirable to provide a kind of Anti-bouncing device of light rail pulley.
(2) technical solution
In order to achieve the above objectives, the Anti-bouncing device of the light rail pulley of the utility model, including pulley and pulley bracket,
Wherein, pulley and pulley bracket axis connection, further include Anti-tripping structure, and the Anti-tripping structure includes that the first anti-jump component and second are anti-
Jump component, the two sides for the pulley that the first anti-jump component and the second anti-jump component respectively symmetrically are arranged；Described first is anti-jump
The both ends of component are provided with the first barb, and the both ends of the second anti-jump component are provided with the second barb；Described first falls
Hook portion and the second barb are staggered and are placed in the track groove of sliding rail.
Further, the upper end of first barb is the first support portion, and the upper end of second barb is second
Support part, first support portion and the second support portion be staggered after overall width be less than track groove notch width.
Further, the pulley includes inner ring and outer ring, wherein outer ring is projectedly arranged on inner ring, and the width of inner ring
Degree is greater than outer ring；The outer ring insertion track groove is rolled, and the inner ring is just rolled on the slide rail.
Further, the two sides of the notch are respectively the first anti-jump end and the second anti-jump end, wherein first barb
Positioned at the lower section at the first anti-jump end, second barb is located at the lower section at the second anti-jump end.
Further, the end of first barb and the second barb is arc.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the advantage that the light rail pulley of the utility model
Anti-bouncing device, in sliding door when by quick-make or shock, occur left and right bounce, can by Anti-tripping structure barb limit
It makes, i.e., pulley plays the role of derailing without departing from track.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art of the utility model；
Fig. 2 is the side structure schematic diagram of the Anti-bouncing device of the utility model light rail pulley；
Fig. 3 is the Facad structure cross-sectional view of the Anti-bouncing device of the utility model light rail pulley.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figures 2 and 3, the Anti-bouncing device of the light rail pulley of the utility model, including pulley 1 and pulley bracket
2, wherein pulley 1 and 2 axis connection of pulley bracket, further include Anti-tripping structure, and the Anti-tripping structure includes the first anti-jump 3 He of component
Second anti-jump component 4, the two sides for the pulley 1 that the first anti-jump component 3 and the second anti-jump component 4 respectively symmetrically are arranged；Institute
The both ends for stating the first anti-jump component 3 are provided with the first barb 5, and the both ends of the second anti-jump component 4 are provided with the second barb
Portion 6；First barb 5 and the second barb 6 are staggered and are placed in the track groove 8 of sliding rail 7.
The upper end of first barb 5 is the first support portion 9, and the upper end of second barb 6 is the second support portion
10, first support portion 9 and the second support portion 10 be staggered after overall width be less than track groove 8 notch 13 width
Degree does not touch with the generation of sliding rail 7, prevents noise from generating.
The pulley 1 includes inner ring 11 and outer ring 12, wherein outer ring 12 is projectedly arranged on inner ring 11, and inner ring 11
Width be greater than outer ring 12；The outer ring 12 is embedded in track groove 8 and is rolled, and the inner ring 11 is rolled above sliding rail 7.
The two sides of the notch 13 are respectively the first anti-jump end 13 and the second anti-jump end 14, wherein first barb 5
Positioned at the lower section at the first anti-jump end 13, second barb 6 is located at the lower section at the second anti-jump end 14.
Working principle
When there is sliding door shaking, whole sliding door necessarily will appear the offset or shake of a direction, lead to pulley
There is the phenomenon that offset shake, since the first barb and the second barb are located at the lower section at the anti-jump end of notch two sides, thus
The anti-limited slip wheel overall offset in anti-jump end can be caught on, and then prevents the generation of derailing, after sliding door monolithic stability, the first barb
It returns to position, not influence pulley rolling with the second barb.
The end of first barb and the second barb is arc, when facilitating installation, the first barb and second
Barb slides into predetermined position automatically.
Anti-tripping structure is made of plastic material, when pulley is installed to track, can install very along barb Fast Installation
It is convenient.
The Anti-bouncing device of the light rail pulley of the utility model occurs left in sliding door when by quick-make or shock
Right bounce can be limited by the barb in Anti-tripping structure, i.e., pulley plays the role of derailing without departing from track.
In conclusion above embodiment is not the restricted embodiment for being the utility model, the technology of all this fields
The modification or equivalent deformation that personnel are carried out on the basis of the substantive content of the utility model, in the skill of the utility model
Art scope.
