Description

A kind of guardrail resilience part with automatic resilience and positioning function

Technical field:

The utility model relates to the guardrail technology, refers in particular to a kind of guardrail resilience part with automatic resilience and positioning function.

Background technology:

The guardrail of using at children or pet that uses at present, people come in and go out and open behind the guardrail because it does not have the resilience reset function, if forgetting, people close guardrail, it will remain on the state of opening, and makes children or pet lose the obstruction effect, in addition if want guardrail to stay open state, must utilize other object that it is withstood, or hook with hook spare, just can prevent the influence of wind or other external force, use very inconvenient and unreliable.

Summary of the invention:

The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of guardrail resilience part with automatic resilience and positioning function to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of guardrail resilience part with automatic resilience and positioning function, this resilience part includes holder, rotary axle box, pin, spring, one-body molded on the sidewall of rotary axle box have a cover platform, the bottom of cover platform becomes V-type, rotary axle box elongation moulding on the end face of holder has boss, the bottom surface of boss is shaped to inclined end face, and form the through hole that runs through rotary axle box on the boss, the other end of this through hole inclined end face forms reaming, in forming counterbore on the holder with on the end face that rotary axle box cooperates, the bottom surface of this counterbore is shaped to and the corresponding ramped bottom surface of the inclined end face of rotary axle box, and form sleeve column on the ramped bottom surface, sleeve column is processed with through hole, the boss of rotary axle box injects in the counterbore of holder, the upper surface of counterbore also forms and overlaps the inclined plane that platform V-type bottom cooperates, the top on this inclined plane forms the location pit, the through hole of sleeve column and the through hole of boss together are installed with pin, the upper surface of this pin forms cap, and be with spring, there is a clamping mechanism lower surface, one section of spring and pin band cap is placed in the reaming, above-mentioned interface arrangment is to form draw-in groove in the lower surface of pin, is connected with jump ring on this draw-in groove.

Resilience part of the present utility model, it utilizes the elastic force of spring and inclined plane to make guide rail, both combinations realize automatic resilience resetting after guardrail is opened, in addition under the restriction of positioning pit, when the V-type bottom of cover platform turns to the embedding positioning pit, guardrail will be positioned and stay open state, if will close guardrail, makes it skid off positioning pit as long as promote guardrail, under the effect on spring and inclined plane, guardrail cuts out automatically.That this guardrail resilience part has is simple in structure, the location is reliable, easy to use.
