Abstract

The utility model discloses a multipurpose elastic zipper comprising a handle, a U-shaped pulling sleeve and fixed support plates, wherein the handle plays a lever effect and is provided with an installation hole I and an installation hole II; the U-shaped pulling sleeve is provided with an installation hole I; the fixed support plates play a fixed support effect; a pin shaft II is installed in the fixed support plates; the pin shaft II is rotatably installed in the installation hole II of the handle; a pin shaft I penetrating through the installation hole I in the middle of the handle is arranged in the installation hole I at the upper end of the U-shaped pulling sleeve; the distance between the upper end of the handle and the installation hole I is larger than that between the installation hole I and the installation hole II; and an elastic body having an elastic force effect is fixedly installed at the lower end of the U-shaped pulling sleeve. The multipurpose elastic zipper has the characteristics of being reasonable in design, simple in structure, convenient to operate, able to automatically adjust tensioning force in the work process, wide in application scope, low in production cost and convenient to popularize and use.

Description

Multiplex elasticity zip

Technical field

The utility model relates to a kind of locking device, is specifically related to a kind of multiplex elasticity zip.

Background technology

At present, locking device all is widely used in all trades and professions, but elasticity is not with in conventional locking device inside, and the tightening force during work can not be regulated automatically.Conventional locking device is when working environment is comparatively complicated, very easily occur getting loose when particularly the duty of equipment is in rotation or vibrational state, such as locking device of the seed dresser barrel door that is in rotation status etc., thereby locking device easily gets loose and brings hidden danger to safety in production.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of multiplex elasticity zip is provided, and it is reasonable in design, and is simple in structure, easy to operate, and in the course of work, tightening force can be regulated automatically, and is applied widely, and cost of production is low, is convenient to promote the use of.

for achieving the above object, the technical solution adopted in the utility model is: a kind of multiplex elasticity zip, it is characterized in that: comprised leverage and be provided with installing hole one and the handle of installing hole two, be provided with the fixed supported slab that the U-shaped of installing hole one is helped pull a cart and play fixed supporting role, bearing pin two is installed on described fixed supported slab, described bearing pin two is rotatably installed in the installing hole two of described handle, described U-shaped is helped pull a cart and is provided with the bearing pin one that passes described handle middle part installing hole one in upper end installing hole one, the distance that described handle upper end is arrived between described installing hole two greater than described installing hole one to the distance between described installing hole one, the described U-shaped lower end of helping pull a cart is installed with the elastic body with resilient force.

Above-mentioned multiplex elasticity zip is characterized in that: described elastic body is fixedly mounted on the described U-shaped lower end of helping pull a cart by rivet or screw.

Above-mentioned multiplex elasticity zip is characterized in that: described elastic body is elastic rope or spring.

The utility model compared with prior art has the following advantages:

(1) this multiplex elasticity zip is reasonable in design, simple in structure, and it is the cocoa complete operation that operating personnel only need pull handle, and operation is very easy;

(2) the U-shaped lower end of helping pull a cart of this multiplex elasticity zip is fixedly installed elastic body, and therefore its tightening force can be regulated automatically in the course of the work.

(3) this multiplex elasticity zip scope of application is very extensive, and much parts all are convenient to produce or buy very much, thereby its cost of production is very low, is convenient to promote the use of.

Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment

as Fig. 1 to a kind of multiplex elasticity zip shown in Figure 9, comprise leverage and be provided with installing hole one 1-1 and the handle 1 of installing hole two 1-2, the U-shaped that is provided with installing hole one 3-1 helps pull a cart 3 and the fixed supported slab 5 that play fixed supporting role, on described fixed supported slab 5, bearing pin 24 is installed, described bearing pin 24 is rotatably installed in installing hole two 1-2 of described handle 1, described U-shaped is helped pull a cart and is provided with the bearing pin 1 that passes described handle 1 middle part installing hole one 1-1 in 3 upper end installing hole one 3-1, the distance of described handle 1 upper end between described installing hole one 1-1 greater than described installing hole one 1-1 to the distance between described installing hole two 1-2, utilize lever principle can make the operator in use laborsaving, reduce operator's labour intensity.Described U-shaped 3 lower ends of helping pull a cart are installed with the elastic body 6 with resilient force by rivet or screw, described elastic body 6 is elastic rope or spring.

The course of work of the multiplex elasticity zip of the utility model is: as shown in figure 10, the fixed supported slab 5 that passes through that first will this multiplex elasticity zip is arranged on cylinder 7.When closing locking during dodge gate 8, the columnar projections 8-1 that will be positioned on dodge gate 8 is connected with elastic body 6, pulls handle 1, and handle 1 drives U-shaped helping pull a cart and 3 moves upward, and makes U-shaped helping pull a cart 3 drive elastic bodys 6 and strain columnar projections 8-1, thereby dodge gate 8 is locked.When opening locking during dodge gate 8, pull lower handle 1, handle 1 drives U-shaped helping pull a cart and 3 moves downward, and unclamps elastic body 6, thereby elastic body 6 and columnar projections 8-1 are unclamped, and dodge gate 8 can be opened.

The above; it is only preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solutions of the utility model.
