Background

The name of the socket head cap screw, also called socket head cap screw, socket head cap screw and socket head cap screw for short is different, but the meaning is the same. The commonly used socket head cap screws are also 4.8 grade, 8.8 grade, 10.9 grade and 12.9 grade. Also called hexagon socket head cap screw, also called hexagon socket head cap screw.

Patent No. cn202010881052.x discloses an inner hexagon bolt, which comprises a main body, wherein the main body comprises a nut and a screw, and a flat washer and a spring washer are respectively arranged on the screw; a first hexagonal groove is formed in one end, away from the screw, of the screw cap, a threaded hole penetrating to the outer side of the screw cap is formed in the inner wall of each side of the first hexagonal groove, a threaded rod is connected to the inner threads of the threaded hole, and one end of the threaded rod is located in the first hexagonal groove; according to the invention, after the inner hexagon wrench with a smaller model is inserted into the hexagonal groove, the threaded rod is abutted against the outer wall of the inner hexagon wrench, so that the inner hexagon wrench with a smaller model can smoothly rotate the main body, and the main body can be adapted to inner hexagon wrenches with various models.

At present, the following defects exist in the hexagon socket head cap screw: 1. the conventional hexagon socket head cap screw is of an integrated structure and cannot be disassembled and assembled, so that only the whole waste material can be replaced after the screw is partially damaged; 2. the conventional hexagon socket head cap screw is loosened after the assembly is finished. To this end, we propose a combination type hexagon socket bolt.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a combined hexagon socket head cap screw, through at nut one side fixedly connected with internal thread pipe, the internal thread pipe can with carry out threaded connection between the contrary threaded rod, and the opposite side of contrary threaded rod is fixed with the screw rod, then separate the nut part and the screw rod part of bolt, it is convenient to assemble, make things convenient for the split to change spare part simultaneously, and the extrusion backing ring can play the extrusion effect to the suit spring when using the bolt equipment, then further step up fixedly through the bounce of suit spring, can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a combined hexagon socket head cap screw, includes the nut, still includes the screw rod, nut one side fixedly connected with internal thread pipe, internal thread pipe opposite side fixedly connected with suit spring, the backing ring has been cup jointed in the screw rod lateral wall slip, screw rod left side fixedly connected with contrary threaded rod, carry out threaded connection between contrary threaded rod and the internal thread pipe.

Furthermore, an inner hexagonal groove is formed in the outer surface of the nut; the inner hexagonal groove is convenient for inserting a corresponding rotary hexagonal tool.

Furthermore, the external threads of the screw rod and the reverse threaded rod are in the reverse direction; the design screw rod and the external screw thread of contrary threaded rod are the reverse direction each other for can not influence being connected between internal thread pipe and the contrary threaded rod when rotatory nut.

Further, the sleeved spring is sleeved on the outer side wall of the screw rod; the extrusion backing ring can play the extrusion effect to the suit spring during the equipment, then further steps up fixedly through the bounce of suit spring.

Compared with the prior art, the utility model has the advantages that 1, the internal thread pipe is fixedly connected with one side of the nut, the internal thread pipe can be in threaded connection with the reverse threaded rod, the screw rod is fixed on the other side of the reverse threaded rod, then the nut part and the screw rod part of the bolt are separated, the assembly is convenient, the disassembly and the replacement of parts are convenient, and the problems that the internal hexagonal bolt is of an integrated structure, the disassembly and the assembly cannot be carried out, and only the whole waste material can be replaced after the bolt part is damaged are solved; 2. through at internal thread pipe opposite side fixedly connected with suit spring, the screw rod lateral wall slides and has cup jointed the backing ring, and the suit spring cup joints in the screw rod lateral wall, extrudees the backing ring during the equipment and can play the extrusion effect to the suit spring, then further steps up fixedly through suit spring's bounce, has solved in the past and has had not hard up problem after the equipment is accomplished.
