Abstract
The utility model belongs to the technical field of the bolt and specifically relates to bolt that traction motor coupling mechanism used. The bolt comprises a bolt body and a bolt head, wherein the bolt head is fixed at the top end of the bolt body, the bolt body penetrates through a central through hole of the shielding cover, the bolt body and the shielding cover are welded and fixed together, the shielding cover is an arc-shaped cover, an elastic layer and a plurality of elastic pieces are fixed on a concave surface of the shielding cover, a pull rope is connected between the bolt body and the bolt head, and a connecting rod is fixed between the bolt head and the shielding cover. The utility model discloses a cover the junction that covers bolt and mechanism bolt hole through shielding. The buffer protection between the shielding cover and the mechanism is increased by the elastic layer and the elastic piece. The pull rope is used for conveniently pulling out the bolt during disassembly. The bolt can prevent most external dirt from penetrating between the bolt and the mechanism.
Description
Technical Field
The utility model belongs to the technical field of the bolt and specifically relates to bolt that traction motor coupling mechanism used.
Background
After the traction bolt is screwed into the bolt hole, external dirt easily permeates between the bolt and a connected mechanism to cause corrosion, so that the service life of equipment is influenced, and the disassembly of the bolt is seriously influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of current bolt by the filth erosion easily, the utility model provides a bolt that traction motor coupling mechanism used.
The utility model provides a technical scheme that its technical problem adopted is: the bolt for the traction motor connecting mechanism comprises a bolt body and a bolt head, wherein the bolt head is fixed at the top end of the bolt body, the bolt body penetrates through a central through hole of a shielding cover, the bolt body and the shielding cover are welded and fixed together, the shielding cover is an arc-shaped cover, an elastic layer and a plurality of elastic pieces are fixed on a concave surface of the shielding cover, a pull rope is connected between the bolt body and the bolt head, and a connecting rod is fixed between the bolt head and the shielding cover.
According to another embodiment of the present invention, further comprising the elastic layer is a silica gel layer.
According to another embodiment of the present invention, it is further included that the elastic member is a spring.
According to another embodiment of the present invention, further comprising a sealing ring fixed at the opening edge of the shielding cover.
According to another embodiment of the present invention, further comprising the material of the shielding cover is aluminum alloy.
The beneficial effects of the utility model are that, this utility model covers the junction of bolt and mechanism bolt hole through shielding the lid. The buffer protection between the shielding cover and the mechanism is increased by the elastic layer and the elastic piece. The pull rope is used for conveniently pulling out the bolt during disassembly. The bolt can prevent most external dirt from penetrating between the bolt and the mechanism.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure, 1, a bolt body, 2, a bolt head, 3, a shielding cover, 4, an elastic layer, 5, an elastic piece, 6, a pull rope, 7, a connecting rod and 8 are sealing rings.
Detailed Description
Fig. 1 is the utility model discloses a structural schematic diagram, a bolt that traction motor coupling mechanism used, including the shank of bolt 1 and bolt head 2, 1 top of the shank of bolt is fixed with bolt head 2, the shank of bolt 1 passes the center perforation of shielding lid 3, and the shank of bolt 1 with shield lid 3 welded fastening together, shield lid 3 and be the arc lid, shield the concave surface of lid 3 and be fixed with elastic layer 4 and several elastic component 5, be connected with stay cord 6 between the shank of bolt 1 and the bolt head 2, bolt head 2 and shield and be fixed with connecting rod 7 between the lid 3. The elastic layer 4 is a silica gel layer. The elastic member 5 is a spring. And a sealing ring 8 is fixed at the opening edge of the shielding cover 3. The shielding cover 3 is made of aluminum alloy.
As shown in fig. 1, when the bolt body 1 is screwed into the threaded hole, the shielding cover 3 is pressed onto the mechanism connected with the bolt body 1, and the threaded hole of the connecting mechanism is covered by the shielding cover 3. Therefore, the surrounding dirt can be effectively shielded from entering the bolt body 1 and the threaded hole. The sealing ring 8 at the edge of the opening of the screening cover 3 will be applied to the mechanism, thereby increasing the sealing. The elastic layer 4 and the elastic member 5 can increase the buffering elasticity and the supporting force between the shielding cover 3 and the connecting mechanism. The elastic layer 4 is silica gel, so that moisture in the air can be adsorbed, and the corrosion of the bolt is avoided. The pull rope 5 can help a worker pull out the bolt body 1 after the bolt body 1 is disassembled, so that the bolt body 1 is prevented from falling accidentally.
