Description

Telescopic structure of roller skate

Technical Field

The invention relates to the technical field of structural design of roller skates, in particular to a telescopic structure of a roller skate, which is applied to roller skates for renting and has the function of size telescopic.

Background

Roller skates are commonly called roller skates, have the origin in the Netherlands, are competition items which utilize special roller skates as competition tools, and are also a play of life and leisure, and most of today's skaters mainly use straight-line rollers; in terms of the existing consumption level, the roller skates are affordable to most people, however, professional fields for roller skating are still few, so that the roller skates for rental and the roller skating fields still have certain markets, however, as the sizes of feet of people are different, the roller skates for rental need to be prepared for each size, so that the extremely high cost is required, and the phenomenon of foot mismatching still exists in the actual use; and for teenagers, the feet of the teenagers are changed greatly, and the roller skates with different sizes need to be purchased continuously, so that the cost is high.

Disclosure of Invention

The present invention is directed to a telescopic structure of a roller skate to solve the above problems of the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: a telescopic structure of a roller skate, comprising: a pulley block, a base, a rear seat, a rear upper, a front seat, a front upper, a compression spring, a bolt, a limiting block and a hexagonal head, the pulley block is a bottom pulley of a roller skate, the base is fixedly connected with the upper end surface of the pulley block and is shoe-shaped, the upper end surface of the base is provided with a groove, the inner side of the groove is provided with a sliding chute, the rear seat is fixedly connected at the rear end of the base, the rear upper is fixedly connected on the upper end surface of the rear seat, the front seat is connected with the sliding groove of the base in a sliding way, the front upper is fixedly connected with the upper end surface of the front seat, two ends of the compression spring are fixedly connected with the rear seat and the front seat respectively, and two ends of the compression spring respectively extend into the rear seat and the front seat, the bolt passes through the front end of the base and is connected with the front seat through threads, the limiting block is fixedly connected to the bolt and located on the rear side of the front end of the base, and the hexagonal head is fixedly connected to the top end of the bolt.

Furthermore, the front seat and the front upper are provided with a plurality of blocks, the front seats are connected through compression springs, and the front upper blocks are connected through elastic fabrics.

Furthermore, the rear upper and the front upper are connected by elastic fabric.

Furthermore, the front end of the rear seat is provided with an extension surface, the rear end of the front seat is provided with a notch, and the extension surface is matched with the notch.

Compared with the prior art, the invention has the beneficial effects that: the telescopic structure of the roller skate is improved on the basis of the existing roller skate, the base is arranged, the upper part is divided, the sliding seat is correspondingly arranged at the bottom of the upper and can slide on the base, the rear seat and each front seat are unfolded under the action of the compression spring, when the bolt is rotated through the hexagonal head, the front seat at the foremost end is pushed to move backwards, the compression spring is compressed, the shoe body is reduced, and different sizes can be adjusted according to different sizes.

The invention has the advantages of simple structure, easy operation, good use effect and the like.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1-a pulley block; 2-a base; 3-a rear seat; 4-rear upper; 5-front seat; 6-front upper; 7-compression spring; 8-bolt; 9-a limiting block; 10-hexagonal head.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present invention provides a telescopic structure of a roller skate, including: pulley block 1, base 2, back seat 3, back upper of a shoe 4, front seat 5, preceding upper of a shoe 6, compression spring 7, bolt 8, stopper 9, hexagon head 10, pulley block 1 be the bottom pulley of roller skate, base 2 rigid coupling in the up end of pulley block 1, base 2 is the shoe shape, the up end of base 2 is opened flutedly, and the inboard of recess is opened flutedly, back seat 3 rigid coupling in the rear end of base 2, back upper of a shoe 4 rigid coupling in the up end of back seat 3, front seat 5 sliding connection on the spout of base 2 recess, preceding upper of a shoe 6 rigid coupling in the up end of front seat 5, compression spring 7 both ends respectively with back seat 3, front seat 5 rigid coupling, and compression spring 7 both ends stretch into the inside of back seat 3, front seat 5 respectively, bolt 8 pass the front end of base 2, bolt 8 passes through the screw thread and is connected with front seat 5, stopper 9 rigid coupling on bolt 8, stopper 9 is located the rear side of base 2 front end, hexagonal head 10 rigid coupling on the top of bolt 8.

Furthermore, front seat 5 and preceding upper of a shoe 6 be provided with the polylith, and connect through compression spring between the polylith front seat 5, and adopt elastic fabric to connect between the polylith front upper of a shoe 6. The stretching amount is divided, so that the cutting width is reduced, and the comfort level is improved;

furthermore, the rear upper 4 and the front upper 6 are connected by elastic fabric. The elastic fabric can play a role in sealing;
