Compared with the defects in the prior art, the utility model has the beneficial effects that:
the connecting part on the traditional bolt and the rod piece are provided with the cavities which are mutually communicated, then the reinforcing part is arranged in the cavity, and the reinforcing part is arranged at the joint of the connecting part and the rod piece, so that the compression resistance and the deformation resistance of the joint are greatly improved.
Drawings
FIG. 1 is a schematic view of a prior art bolt;
FIG. 2 is a schematic diagram of an explosive structure according to the present utility model;
fig. 3 is a schematic cross-sectional view of the present utility model.
The connecting device comprises an end part 1, a rod part 2, a connecting part 3, external threads 31, a first cavity 10, a second cavity 20, a joint 12, a reinforcing part 4, a fixing unit 41, a supporting unit 42, a plug 5 and a joint 6.
Detailed Description
Embodiments of the present utility model will be further described with reference to fig. 2 to 3.
The specific structure of the embodiment is as follows: the bolt comprises a bolt body, wherein the bolt body comprises an end part 1 and a rod part 2, one end of the rod part 2 is provided with a connecting part 3, and the peripheral wall of the connecting part 3 is provided with external threads 31.
The shaft 2 has a first cavity 10 therein, the first cavity 10 being formed by an opening in the end face of the end 1 extending inwardly to the root thereof. And an internal thread 1a is provided on the inner wall of the first chamber 10.
The connecting part 3 is internally provided with a second cavity 20, and the second cavity 20 is formed by continuously extending and opening the root of the rod part 2 after the first cavity 10 is formed. The compression resistance of the connecting part 3 can be further improved after the cavity II 20 is arranged, and the connecting part has stronger deformation resistance with the same traditional solid structure, and is not easy to bend relative to the solid structure when being stressed.
So that the cavity two 20 and the cavity one 10 are communicated, wherein the diameter of the cavity one 10 is larger than that of the cavity two 20, and a step part is formed at the joint of the cavity one 10 and the cavity two 20. By providing the reinforcing member 4 at the joint 6, the structural strength therebetween is improved.
The reinforcing member 4 is hollow and comprises a fixing unit 41 and a supporting unit 42, external threads in threaded connection with the first cavity 10 are arranged on the peripheral wall of the fixing unit 41, and the supporting unit 42 stretches into the second cavity 20 and abuts against the inner wall of the second cavity. The end face of the fixing unit 41 is provided with a cross-shaped groove.
During installation, the reinforcing member 4 is inserted from the opening 100 at the end, and then is abutted against the cross groove 40 on the fixing unit 41 by the electric drill, so that the reinforcing member 4 is driven to rotate along the internal thread in the first cavity 10 until the supporting unit 42 extends into the second cavity 20 to abut against the inner wall of the second cavity 20. And finally, sealing the opening formed in the end part through the plug. The plug can be made of rubber, or the outer wall of the plug is in threaded connection with the inner wall of the first cavity 10 through threads.
The supporting unit 42 is also hollow, ensuring its own structural strength. The diameter of the second cavity 20 is gradually decreased from one end to the other end, the cross section of the second cavity is in a truncated cone shape, the supporting unit 42 is also in a truncated cone shape, the diameter of the supporting unit 42 is slightly larger than the inner diameter of the second cavity 20, and the supporting unit 42 has certain tension. When the supporting unit 42 and the pressing force thereof are pressed against each other, the pressing force of the supporting unit 42 against the same can be further increased.
The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model, but one skilled in the art can make common changes and substitutions within the scope of the technical solution of the present utility model.
