Abstract
The utility model relates to a roller telescopic mechanism for a pair of roller boots. A fixing support is fixed in a preformed groove of a sole; an arc-shaped groove and a thrust groove are communicated with each other and are arranged on the fixing support; rollers are fixed to one end of a movable support through a shaft; a sliding pin arranged on the other end of the movable support is matched with the arc-shaped groove and a thrust groove fixed on the fixing support; the end part of the movable support under a roller shaft is abutted on an edge port of the groove; both ends of a tension spring are respectively fixed on the fixing support and the movable support. The utility model overcomes the defects of complicated structure in the prior art, low reliability and short service life; the utility model has the advantages of simple structure; light weight, strong reliability and good shockproof effect.
Description
The utility model relates to a kind of footwear pulley telescoping mechanism that slides.
Existing various slide footwear generally adopt the hinge link or in flakes link wheel shaft is coupled together, be equipped with the retractor device and the locking device of wheel shaft again, reach the collection of pulley and stretch out, the function that footwear is had slide and walk.But their structure is more complicated all, and movable joint will be by riveting process, Heavy Weight, be not easy to child uses.Simultaneously, the above-mentioned locking device that slides footwear is unreliable, causes foot to sprain or the damage of gliding member easily.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thus a kind of simple in structure, easy to use, good reliability is provided slide footwear pulley telescoping mechanism.
The utility model comprises fixed support, travel(l)ing rest, extension spring and pulley, fixed support is packed in the preformed shrinkage pool of sole, which is provided with the deep-slotted chip breaker and the thrust groove that are interconnected, pulley is fixed on travel(l)ing rest one end by axle, being arranged on the sliding pin of the travel(l)ing rest other end matches with deep-slotted chip breaker and thrust groove on the fixed support, the travel(l)ing rest end of pulley spindle below and the edge mouth of shrinkage pool offset, and the two ends of extension spring are separately fixed on fixed support and the travel(l)ing rest.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model collecting state;
Fig. 2 is the structural representation of the utility model user mode.
As shown in the figure, the utility model comprises fixed support 1, travel(l)ing rest 2, extension spring 3 and pulley 4, and fixed support 1 and travel(l)ing rest 2 are all made by aluminum alloy materials, can effectively reduce weight.Fixed support 1 is packed in the preformed shrinkage pool 5 of sole, which is provided with the deep-slotted chip breaker 6 and the thrust groove 7 that are interconnected, pulley 4 is fixed on travel(l)ing rest 2 one ends by axle 8, being arranged on the sliding pin 9 of travel(l)ing rest 2 other ends matches with deep-slotted chip breaker 6 and thrust groove 7 on the fixed support 1, travel(l)ing rest 2 ends of pulley spindle 8 belows and the edge mouth 10 of shrinkage pool 5 offset, and are provided with shockproof wedge cushion block 11 in the sole of edge mouth 10 belows.The two ends of extension spring 3 are separately fixed on fixed support 1 and the travel(l)ing rest 2.During use, with pulling out travel(l)ing rest 2, because the effect of extension spring 3, after loosing one's grip, sliding pin 9 enters thrust groove 7, and the edge mouth 10 of the rearward end of travel(l)ing rest 2 and shrinkage pool 5 offsets.At this moment, sliding pin 9 is in a plane with the rearward end of travel(l)ing rest 2.As desire collection pulley 4, only need sliding pin 9 is pulled out thrust groove 7, the contraction strength of mat extension spring 3 can be retracted to the deep-slotted chip breaker top together with pulley 4 automatically with travel(l)ing rest.At this moment, sole part is unlikely to be deviate from because the contraction of extension spring 3 abuts against for travel(l)ing rest 2.Be given a shock in pulley 4 is sliding or when impacting, shockproof wedge cushion block 11 can slide up and down in corresponding wedge groove, play the bumper and absorbing shock effect, this cushion block can also carry most human body weight, the load that has effectively alleviated sliding pin 9 and thrust groove 7.
The utility model is by above-mentioned specific design, have simple in structure, practical and convenient, that shockproof effect is good is excellent The point. Simultaneously, owing to adopted the aluminium condensation material, make the weight saving of integrated model about 1/3rd, during use Light again comfortable.
