Description

A kind of hand pulls the suspension hook of turnbuckle and the attachment structure of hook housing

【Technical field】

It the utility model is related to a kind of hand and pull the suspension hook of turnbuckle and the attachment structure of hook housing, belong to hand and pull turnbuckle technology Field.

【Background technology】

Hand pulls turnbuckle and is widely used in the occasions such as national grid, warehouse, harbour, power station, logging headquarter, supply lines, cable Good stringing effect is played in operation is tensed.

Refer to shown in Fig. 1,2,3,4,5, in existing hand pulls turnbuckle, suspension hook 1 with hook housing is carried out by means of hook beam 2 Connection.Hook beam 2 has the hook beam body 21 of square and is symmetrically extended the collar 22 formed by hook beam body 21, wherein, Hook beam body 21 offers through hole 210, and the neck of hook 11 of suspension hook 1 is set through this through hole 210, and the outer peripheral edge of the neck of hook 11 and hook beam Raceway is formed between the hole wall of body 21, offers an axial aperture 220 for connecting this raceway on a collar wherein； Hook housing has spaced apart two blocks of hook housing plates 4, and two blocks of hook housing plates 4 symmetrically offer pivot hole 40.

When hook beam 2 is assembled on suspension hook 1, first by 2 sets of necks of hook 11 for being attached to suspension hook 1 of hook beam, then toward axial aperture Ball 3 is put into 220, until the full raceway of the arrangement of ball 3, is then screwed in for blocking axial aperture 220 toward axial aperture 220 Screw K, ball 3 is set to be constrained in raceway.

After hook beam 2 assembles with suspension hook 1, then it is about to the assembly and connection of suspension hook 1 between two blocks of hook housing plates 4, makes hook beam 2 Two collars 22 are plugged in the pivot hole 40 of corresponding hook housing plate respectively, and so far suspension hook 1, hook beam 2 and hook housing three complete assembling Operation.

Because the collar 22 of hook beam 2 is hubbed in the pivot hole 40 of hook housing plate 4, collar 22 can be around pivot hole 40 Rotate, make the free degree of the beat of suspension hook 1 unfettered, in wire stringing operation force part be at the collar 22 of hook beam 2, by Suspension hook 1 under power state can offset (such as Fig. 5) along the interval extending space direction of two blocks of hook housing plates 4, so then cause suspension hook 1 Its hook chamber 1Y center and the axle center of collar 22 not on a stress straight line, ultimately result in each row chain in multirow chain by Power is uneven.

In addition, it is necessary to it is deep into the through hole 210 of hook beam body 21 and goes out the outer peripheral edge with the neck of hook 11 in its inwall processing The raceway to match, virtually increases mechanical processing difficulty on foot, and processing technology is complicated.

【Utility model content】

The technical problems to be solved in the utility model is to provide a kind of hand for above-mentioned the shortcomings of the prior art and pull The suspension hook of turnbuckle and the attachment structure of hook housing.

Technical scheme is as follows used by the utility model solves above-mentioned technical problem：

A kind of hand pulls the suspension hook of turnbuckle and the attachment structure of hook housing, including the suspension hook with the neck of hook and symmetrical configuration, can The hook housing pair of pairing assembling, the neck of hook offer semicircle shallow trench in its outer peripheral edge, and its improvement is：Also include leading to step The ball base in hole, ball base is arranged the neck of hook, and a whole circle is placed between the step of step through-hole and the semicircle shallow trench of the neck of hook Ball, the semicircle straight trough to match with the neck of hook is symmetrically offered in the inwall of two hook housings, and the inwall of two hook housings is symmetrical The semicircle translot rocked for limiting ball base is offered, the neck of hook is in the semicircle straight trough of two hook housings, ball seat In the semicircle translot of two hook housings.

Above-mentioned semicircle straight trough is with semicircle translot in the cross intersected.

The utility model this have the advantage that compared with prior art：

The utility model sets up ball base, and hook housing symmetrically opens up semicircle straight trough and semicircle translot to inwall, by When wire stringing operation force part be at ball base, two semicircle translots play a part of limit ball base rock, suspension hook by Ball base is constrained between two hook housings thus suspension hook is no longer produced skew during power, so then causes the center of its hook chamber of suspension hook It is in the step through-hole center of ball base on a stress straight line, uniform load is distributed in each row in multirow chain during stringing On chain.

The step through-hole simple processing of ball base, ball is available between the step of step through-hole and the semicircle shallow trench of the neck of hook Assembling, realizes 360 degree of rotating functions of suspension hook.

【Embodiment】

Refer to shown in Fig. 6,7,8,9,10, be preferred embodiment of the present utility model.

A kind of hand pulls the suspension hook of turnbuckle and the attachment structure of hook housing, including suspension hook 1 and symmetrical configuration with the neck of hook 11, Can pairing assembling hook housing pair, the neck of hook 11 offers semicircle shallow trench 110 in its outer peripheral edge, and its improvement is：Also include tool There is the ball base 2 of step through-hole 20, ball base 2 is arranged the neck of hook 11, and the semicircle of the step 200 and the neck of hook 11 of step through-hole 20 is shallow A whole circle ball 3 is placed between groove 110, the semicircle to match with the neck of hook 11 is symmetrically offered in the inwall of two hook housings 4 Shape straight trough 41, and the inwall of two hook housings 4 symmetrically offers the semicircle translot 42 rocked for limiting ball base 2, the neck of hook 11 In the semicircle straight trough 41 of two hook housings 4, ball base 2 is in the semicircle translot 42 of two hook housings 4.

Semicircle straight trough 41 is with semicircle translot 42 in the cross intersected.

Semicircle shallow trench 110 is to surround 11 1 weeks outer peripheral edges along the neck of hook 11 of the neck of hook to open up, the semicircle shallow trench 110 and rolling The step 200 of pearl seat 2 forms the raceway installed for a circle ball 3.

When suspension hook 1 assembles with ball base 2, the neck of hook 11 of suspension hook 1 is extended to the portlet of the step through-hole 20 of ball base 2, Make the neck of hook 11 upward, then toward a circle ball 3 is covered with the step 200 of ball base 2, then take advantage of a situation and up push away suspension hook 1, until rolling Pearl 3 is placed in the semicircle shallow trench of the neck of hook 11, as shown in fig. 6, ball 3 is quick and easy for installation and directly perceived, no after assembling Can neglected loading ball 3.

By hook housing to carrying out pairing assembling after, the combination of semicircle straight trough 41 of two hook housings 4 forms a complete blind hole, should The internal diameter of blind hole is adapted with the external diameter of the neck of hook 11, and the combination of semicircle translot 42 of two hook housings 4 forms a complete blind hole, The internal diameter of this blind hole is adapted with the external diameter of ball base 2.

When being equipped with ball base 2, ball 3, the sub-assembly of suspension hook 1 and hook housing to assembling, first place a hook housing 4 and make it Inwall upward, then places above stated assembly, makes the neck of hook 11, ball base 2 respectively fitted to semicircle straight trough 41, semicircle translot In 42, finally close another structure identical hook housing 4 and tighten fastening bolt S, it is whole easy to assembly quick.

During wire stringing operation, force part is on the upper end anchor ring of ball base 2, i.e., its step through-hole 20 of ball base 2 is small In one side where port.
