Abstract

The utility model discloses an inserted pin used for hinge pin locking, which comprises an inserted pin, a locking sleeve, a hinge pin, a clamping pin, a snap spring and the like. The utility model is characterized that the inserted pin is formed by a T-shaped cylindrical pin with two staggered through holes on the head part and a circular spring steel wire the two ends of which are staggered, and the two ends of the circular spring steel wire are respectively inserted into the two through holes of the T-shaped cylindrical pin for a certain distance. When the hinge pin is fixed by the inserted pin, the spring steel wire is wound around the through holes of the T-shaped cylindrical pin and is wrested to the root part of the T-shaped cylindrical pin by hands. When the spring steel wire is close to the root part of the T-shaped cylindrical pin, the spring force produced by stretching the spring steel wire makes the steel wire closely lean on the cylindrical pin so as to make the entire pin stay in a self-locking state and prevent the inserted pin from dropping simultaneously. When the inserted pin is dismounted, the spring steel wire is wound around the through holes of the T-shaped cylindrical pin by hands, and is wrested to the direction opposite to the inserting direction of pin so as to easily pull out the inserted pin. The utility model has advantages of simple structure, easy manufacture, low cost, obvious effect and the like.

Description

A kind of latch that is used for bearing pin stop

Technical field

The utility model relates to a kind of latch that is used for bearing pin stop, particularly a kind of hydraulic shovel bearing pin means of retention.

Background technique

At present, the means of retention of general hydraulic shovel bearing pin stop latch mainly is by using stay bolt to pass bearing pin stop cover pin-and-hole and bearing pin pin-and-hole, force tightly at a distance, in case screw bolt and nut comes off with double nut at the bolt the other end then from the about 2～3mm of bearing pin stop cover cylindrical.Owing to used double nut to force tight structure mutually, this bearing pin means of retention dismounting efficient is not high, and each mounting or dismounting all need two spanners extremely to bother.

Summary of the invention

It is the T shape straight pin that a head has dislocation through hole that the purpose of this utility model is to provide a kind of bayonet lock, and jump ring is the Spring Steel Wire of the annular that staggers of a two ends.The jump ring card is crossed bayonet lock stop cover, bearing pin three admittedly together.Dismounting efficient height, need not the hydraulic shovel bearing pin stop latch of spanner.

Technical solution of the present utility model is such: comprise latch, stop cover, bearing pin, bayonet lock, jump ring, it is characterized in that: latch passes stop cover pin-and-hole and bearing pin pin-and-hole, the termination of staggering of jump ring is entrapped in the dislocation through hole of latch, and be spun on stop cover bottom, stop cover and bearing pin are fixed together.

Latch is made up of bayonet lock and jump ring, and jump ring is screwed into the root of bayonet lock around the through hole of bayonet lock, and the stop cover packed tightly at bearing pin tightens up, and jump ring is tightly against bayonet lock.

The head of bayonet lock has the T shape straight pin of two dislocation through holes, and jump ring is the two ends annular spring steel wire of termination that staggers.

Adopt the bearing pin means of retention of technique scheme, very convenient, fast when disassembling and assembling pin shaft.The utility model latch just has the T shape straight pin of two dislocation through holes by a head and the Spring Steel Wire of the annular that two ends staggers is formed, and is simple in structure, easily manufactured, with low cost, effect is obvious.Be a kind of dismounting efficient height, need not the excavator bearing pin means of retention of spanner, low cost of manufacture.

Description of drawings

It is such that structure of the present utility model constitutes:

Fig. 1 is the structural representation of the existing bearing pin means of retention of general excavator.

Fig. 2 is the structural representation that the utility model is used to use the bearing pin stop of the utility model latch.

Fig. 3 is the left view by Fig. 2 of the utility model latch of being used for bearing pin stop.

Fig. 4 is that the jump ring that the utility model is used for bearing pin stop inserts the plan view that bayonet lock is combined into the latch structure latch.

Fig. 5 is that the jump ring that the utility model is used for bearing pin stop inserts the left view that bayonet lock is combined into the latch structure latch.

Fig. 9 is the plan view of the jump ring of the utility model latch of being used for bearing pin stop.

Among Fig. 1 to Fig. 9: latch (1), stop cover (2), bearing pin (3), bayonet lock (4), jump ring (5), dislocation through hole (6), the termination of staggering (7).

Embodiment

Most preferred embodiment of the present utility model is such, and referring to figs. 1 through Fig. 9, with reference to Fig. 2 and Fig. 3, latch (1) passes stop cover (2) pin-and-hole and bearing pin (3) pin-and-hole, and stop cover (2) and bearing pin (3) are fixed together.

With reference to Fig. 4, Fig. 5, latch (1) is made up of bayonet lock (4) and jump ring (5), when jump ring (5) is screwed into the root of bayonet lock (4) around the through hole of bayonet lock (4), jump ring (5) has been subjected to stretching, jump ring (5) will be automatically tightly against bayonet lock (4), simultaneously, stop cover (2) bag cable is lived, utilize the pulling force tension of bayonet lock (4) extremely not separate mutually at bearing pin (3).Insert when unloading bearing pin (3), jump ring (5) is pulled away from stop cover (2), can extract latch (1) and bearing pin (3).

With reference to Fig. 6, Fig. 7, bayonet lock (4) is the T shape straight pin that a head has two dislocation through holes.

With reference to Fig. 8, Fig. 9, jump ring (5) is the Spring Steel Wire of the annular that staggers of a two ends.

[0023] replace stay bolt and double nut to fix the hydraulic shovel bearing pin with an easy accessibility latch.This latch has the T shape straight pin of two dislocation through holes by a head and the Spring Steel Wire of the annular that two ends staggers is formed, and annular spring steel wire two ends is inserted two through hole one segment distances of T shape straight pin respectively.During the latch fixed pin shaft, break root with the handgrip Spring Steel Wire off with the fingers and thumb around the through hole of T shape straight pin to T shape straight pin, when the root of close T shape straight pin, Spring Steel Wire has been subjected to stretching, and the spring force that produces makes steel wire automatically tightly against straight pin, thereby make whole latch be in self-locking state, prevented that also latch from coming off simultaneously; Dismounting is during latch, only with hand Spring Steel Wire around T shape straight pin small through hole break off with the fingers and thumb to the opposite direction of latch direction of insertion, just can easily latch be extracted.The utility model only needs stay bolt, double nut are replaced with latch on the basis of original pin shaft (3) and stop cover (2), realizes a kind of dismounting efficient height easily, need not the excavator bearing pin means of retention of spanner, low cost of manufacture.Do not limit use on hydraulic shovel bearing pin means of retention, may also extend on the bearing pin means of retention of engineering machinery such as loader.
