The utility model has a large operating space and is easier to install. It is convenient and intuitive, and can overcome the phenomenon of the wedge being stuck at the same time. In addition, the utility model can be used repeatedly, which greatly reduces the use cost.

Description

Novel bolt push-to-close wire clamp

Technical field

The utility model relates to a kind of connector that is used for the high-low voltage transmission-distribution line road, is a kind of novel bolt push-to-close wire clamp specifically.

Background technology

Mainly there are following shortcoming in present domestic existing wedge clamp and screw bolt-type wedge clamp:

1, the bolt operating position is on the top of C shape matrix, i.e. microcephaly receives the obstruction of lead; The space of operating screw is very little, and particularly along with the transformation of line insulationization, insulated wire is widely applied; Thick insulating barrier makes that the operating space of bolt is littler, and inconvenience more is installed;

2, workmen's difficulty and intensity has been strengthened dorsad away from the workmen in the bolt operating position;

3, owing to be to utilize the operation of bolt pulling voussoir, in installation process, lead and voussoir can not coincide sometimes, voussoir can occur and blocked phenomenon, install not in place;

4, the wire clamp dismounting needs first loose bolts to knock screw rod then to eject voussoir, be easy to the thread damage voussoir like this, the influence repeated use;

5, the lengthening of voussoir makes that the specification of wire clamp adaptation lead is wideer, helps user's type selecting.

Summary of the invention

The technical assignment of the utility model is to above-mentioned technical deficiency, and novel bolt push-to-close wire clamp is provided.

The technical scheme that the utility model technical solution problem is adopted is: the bolt that comprises C shape base seat, is placed on the voussoir in the C shape base seat and connects C shape base seat, voussoir; Said bolt comprises just twists fastening part, locking fastening part, threaded joints and connects the connecting portion of autotomying of just twisting fastening part and locking fastening part, and wherein said threaded joints links to each other with the locking fastening part, and said threaded joints diameter is greater than the connecting portion diameter of autotomying; Said C shape base seat is the bigger C shape part in the less rear end of front end; Said voussoir is the bigger wedge shape in the less rear end of front end, and the both sides of said voussoir are equipped with deep-slotted chip breaker, and the front end of said C shape base seat inwall is provided with protruding connecting portion; Said connecting portion is provided with screw; Said voussoir one side is provided with groove and stop part, and its further groove is at the voussoir front end, and stop part is in the voussoir rear end; Said stop part is provided with guide hole; The connecting portion of said C shape base seat raising matches with the groove on the voussoir, makes that the connecting portion on the C shape base seat can slide along the groove on the voussoir, and said bolt passes the guide hole on the voussoir and can be tightened in the screw on the C shape base seat.

The beneficial effect that the utility model can bring is:

1, since the bolt installation position in the rear end of C shape base seat, the operating space is big, simultaneously direction is installed directly perceived, easy, quick towards the workmen;

2, owing to be through tightening bolt, it is up and compress lead to promote voussoir, and having overcome voussoir is blocked phenomenon, need not expensive professional tool, only needs common torque spanner to get final product;

3, the extended length of voussoir, after guaranteeing to install, voussoir is a little more than the rear and front end of C shape matrix, and when dismounting, the counter-rotating bolt directly knocks the head of voussoir, can withdraw from voussoir, dismantles simplyr, reusable, has practiced thrift use cost greatly.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done following detailed description:

Like accompanying drawing 1, Fig. 2 and shown in Figure 3; The utility model provides a kind of novel bolt push-to-close wire clamp, and the bolt that comprises C shape base seat 1, is placed on the voussoir 2 in the C shape base seat 1 and connects C shape base seat 1, voussoir 2, said bolt comprise just twists fastening part 3, locking fastening part 4, threaded joints 6 and connect the connecting portion 5 of autotomying of just twisting fastening part 3 and locking fastening part 4; Wherein said threaded joints 6 links to each other with locking fastening part 4; And said threaded joints 6 diameters are greater than connecting portion 5 diameters of autotomying, and said C shape base seat 1 is the bigger C shape part in the less rear end of front end, and said voussoir 2 is the bigger wedge shape in the less rear end of front end; The both sides of said voussoir 2 are equipped with deep-slotted chip breaker 7; The front end of said C shape base seat 1 inwall is provided with protruding connecting portion 8, and said connecting portion 8 is provided with screw 9, and said voussoir 2 one sides are provided with groove 10 and stop part 11; Its further groove 10 is at voussoir 2 front ends; Stop part 11 is in voussoir 2 rear ends, and said stop part 11 is provided with guide hole 12, and the connecting portion 8 of said C shape base seat 1 raising matches with the groove 10 on the voussoir 2; Make the connecting portion 8 on the C shape base seat 1 to slide along the groove on the voussoir 2 10, said bolt passes the guide hole 12 on the voussoir 2 and can be tightened in the screw 9 on the C shape base seat 1.

The bolt installation position of the utility model is in the rear end of C shape base seat 1, and the operating space is big, and direction is installed directly perceived, easy, quick towards the workmen simultaneously; Simultaneously, owing to be to promote the voussoir 2 up leads that compress, overcome voussoir 2 by the card phenomenon through elasticity bolt.In addition, said voussoir 2 length are greater than C shape base seat 1 length, and after installing like this, voussoir 2 is a little more than the rear and front end of C shape base seat 1; When dismounting, the counter-rotating bolt knocks voussoir 2, can withdraw from voussoir 2; Dismantle simplyr, reusable, greatly reduce use cost.
