Abstract

The utility model discloses a belt hook with a bearing hole. The belt hook creatively adopts the structure that the bearing hole is disposed on a hook end surface of a belt hook body. When the belt hook is used for being connected with an annular connector inside the hook, an inserting pin of the belt hook is inserted inside the bearing hole, a joint seam between the inserting pin and the hook end surface can be eliminated, and a joint of the inserting pin and the hook end surface is locked. The inserting pin can increase capabilities of bearing lateral dragging force of the annular connector and preventing hook releasing, thereby greatly improving tensile property of the belt hook for pulling beasts and prolonging service life of the belt hook.

Description

Alligator with support holes

Technical field:

The utility model relates to a kind of alligator with support holes.Its purposes be mainly used in the traction beasts when (comprising that the dog class is as follows) as the quick connector tool between beasts necklace and traction belts; Also be applicable between the various ribbons (band, rope, chain etc.) and with quick connection that has between the ring joint object.

Background technology:

The alligator (see figure 1) of prior art comprises coupler body 1, draw ring 2, compression spring 3 and latch 4.Described coupler body one end has gib head, and its sweep can hook ring joint (comprising that the beasts necklace is as follows), and the coupler body other end forms the uncovered of coupler body for the straight tube of band blind hole, the blind hole openend of straight tube and the gib head end face of coupler body; The straight tube other end connects draw ring, and draw ring can freely turn round in the cannelure that this end end of straight tube is provided with; The compression of packing in the blind hole of straight tube reinstalls latch behind the spring, the latch termination can be stretched out from the blind hole openend of straight tube, under nature, the latch termination withstands on the gib head of coupler body under the compression spring action, reach and close the uncovered purpose of coupler body, do not break off relations, when the knob head on the promotion latch to block ring joint, can return latch, unlimited uncovered, make ring joint break away from alligator, reach the object disengaging alligator of decontroling beasts or having ring joint.The deficiency that this kind structure exists is: because coupler body is not provided with between support holes latch and gib head end face and has seam; Latch bears the ring joint side direction and drags the power poor-performing, beasts with traction belts traction, when particularly using the traction belts ridding bitt, run into beasts and cross the excitation force state, the latch of alligator easily by beasts drag curved, drag the disconnected beasts necklace that causes and break away from alligator, beasts are escaped; Cause alligator to scrap simultaneously, shorten service life; Moreover, because the existence of seam between this latch and gib head end face causes the unhook phenomenon to become possibility, so its mousing-hook ability is relatively poor.

Summary of the invention:

In view of the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides that a kind of latch that can strengthen alligator is counter-bending, the alligator with support holes of anti-shear performance.

The purpose of this utility model is achieved in that described alligator with support holes, comprise coupler body, draw ring and latch, coupler body one end has gib head, its sweep can hook the object that ring joint connects, the coupler body other end forms the uncovered of coupler body for the straight tube of band blind hole, the blind hole openend of straight tube and the gib head end face of coupler body; The straight tube other end connects draw ring, and is connected with traction belts by this draw ring; Packing in the blind hole of straight tube is provided the latch of pressure by the compression spring, its design feature is for being provided with the support holes that termination size, shape, an extension elongation of stretching out with latch is complementary and can just inserts on the gib head end face of coupler body.

Characteristics of the present utility model with advantage are: with the coupler body of the alligator of prior art support holes is not set and compares, alligator (hereinafter to be referred as the utility model alligator) with support holes, the utility model has creatively adopted a support holes has been set on the gib head end face of coupler body, when being connected use with ring joint in the hook, the latch of alligator inserts in this support holes.Its advantage is: eliminated the seam between alligator latch and gib head end face, its junction is by locking; With the cantilever beam stress by an end bearing of this latch from the alligator of prior art, become the simply supported beam stress by two supports of the utility model alligator, improved the counter-bending of this latch and shear-stable performance significantly; Improved the utility model alligator side direction (B-B direction) and (A-A direction) tensile property in performance test; This latch can have been improved significantly bear power and anti-locking hook are dragged in ring joint to its side direction ability; Thereby improved the tensile property of the utility model alligator traction beasts etc. (easily latch being produced the power of dragging of side direction when drawing two above ring joints simultaneously) significantly; Strengthened and prolonged mousing-hook; The service life of energy the utility model alligator.

Description of drawings:

Fig. 1 is the prior art constructions schematic diagram.

Fig. 2 is the structural representation of the utility model embodiment.

Among the figure: coupler body 1, draw ring 2, compression spring 3, latch 4, straight tube 5, support holes 6, ring joint 7, traction belts 8, object 9.

Embodiment:

Below in conjunction with drawings and Examples the utility model is elaborated:

As shown in Figure 2, be the alligator of the utility model embodiment, comprise coupler body 1, draw ring 2, compression spring 3 and latch 4 (which is provided with to have and promote the knob head that latch is used) with support holes.Described coupler body one end has gib head, and its sweep can hook ring joint 7, and the coupler body other end forms the uncovered of coupler body for the straight tube 5 of band blind hole, the blind hole openend of straight tube and the gib head end face of coupler body; Straight tube 5 other ends connect draw ring 2, and are connected with traction belts 8 by this draw ring; Draw ring can freely turn round in the cannelure that this end end of straight tube is provided with; The compression of packing in the blind hole of straight tube reinstalls latch behind the spring 3, under nature, in the support holes 6 of latch 4 terminations gib head end face of insertion coupler body 1 under 3 effects of compression spring, reach close coupler body uncovered, do not break off relations to block ring joint, when the knob head on the promotion latch, can return latch, open wide uncoveredly, the object 9 that makes the beasts necklace or have a ring joint 7 breaks away from alligators, reaches and decontrols beasts or separating objects purpose.The utility model design feature is for being provided with a support holes 6 on the gib head end face of coupler body 1, described support holes 6 sizes, shape, the degree of depth and place the termination of stretching out of the latch 4 in the straight tube blind hole to be complementary are stretched out in the support holes 6 on the gib head that can just insert coupler body 1 thereby can reach latch 4 its termination under 3 effects of compression spring.
