Problems solved by technology

As the construction machinery performs related operations, the vibration generated in the motor transmission and the vibration generated during the operation will be transmitted to various parts of the construction machinery, and the bolts on the connection parts will be continuously loosened, resulting in the instability of the connection parts of the construction machinery
This not only increases the maintenance frequency of construction machinery, but also the bolts are completely loosened, and the related parts will fall off, which will cause unnecessary engineering losses

Embodiment 1

[0030] Such as Figure 1-Figure 6 As shown, the anti-loosening bolts for connecting parts of the present invention include a bolt 1, and a threaded through hole 2 is arranged on the bolt 1, and the axis of the threaded through hole 2 coincides with the axis of the bolt 1, and the threaded through hole 2 is provided with There is a screw 3, the screw 3 cooperates with the threaded through hole 2, and the end of the screw 3 away from the head of the bolt 1 passes through the threaded through hole 2 from the end of the rod of the bolt 1, and an extrusion plate 4 is arranged at this end , the extruded plate 4 is bent into a C shape, the inner concave surface of the extruded plate 4 is connected with the screw rod 3, and the projection of the extruded plate 4 along the axis of the bolt 1 can fall on the end surface of the rod of the bolt 1;

[0031] Rotate the screw 3 to move the end of the screw 3 away from the head of the bolt 1 to the head of the bolt 1, and make the extruded pl...

Embodiment 2

[0034] The present invention is based on embodiment 1, and the present invention is further described.

[0035] Such as Figure 1-Figure 6 As shown, the anti-loosening bolts for parts connection of the present invention are provided with a guide groove 5 on the side of the screw rod 3 near the end of the extruded plate 4, the axis of the guide groove 5 is parallel to the axis of the screw rod 3, and on the extruded plate A guide block 6 is arranged on the end of 4, and the guide block 6 cooperates with the guide groove 5.

[0036] The opening size of the guide groove 5 is smaller than the bottom size of the groove, and the cross-sectional size of the guide block 6 is consistent with the cross-sectional size of the guide groove 5 . There are two guide grooves 5, which are symmetrically arranged on the side wall of the screw rod 3 along the axis of the screw rod 3; a guide block 6 is arranged on both ends of the extrusion plate 4, and the guide grooves 5 are respectively Coope...

Embodiment 3

[0039] The present invention is based on embodiment 1, and the present invention is further described.

[0040] Such as Figure 1-Figure 6 As shown, the anti-loosening bolts used for connecting parts of the present invention are provided with an anti-loosening spring 7 on the inner concave surface of the extrusion plate 4, and one end of the anti-loosening spring 7 is far away from the inner concave surface of the extrusion plate 4. The surfaces of the 4 ends are connected, and the other end of the anti-loosening spring 7 is connected with the surface near the end of the extruding plate 4 on the inner concave surface of the extruding plate 4. After the extruding plate 4 is deformed, the anti-loosening spring 7 is in a compressed state.

[0041] The anti-loosening spring 7 in the compressed state generates thrust on the surface far away from the end and the surface close to the end on the extrusion plate 4, and the surface far from the end on the extrusion plate 4 is fixedly conn...

Abstract

The invention discloses a lock bolt used for part connection. The lock bolt comprises a bolt body. The bolt body is provided with a threaded through hole. The axis of the threaded through hole coincides with that of the bolt body. A screw rod matched with the threaded through hole is arranged in the threaded through hole, and the end, far away from the head portion of the bolt body, of the screw rod penetrates out of the threaded through hole and is further provided with squeezing plates. Each squeezing plate is bent to be in a C shape. The inward-recessed faces of the squeezing plates are connected with the screw rod, and the projections of the squeezing plates along the axis of the bolt body can both fall off onto the end face of the rod portion of the bolt body. By rotating the screw rod, the end, far away from the head portion of the bolt body, of the screw rod can move towards the head portion of the bolt body, the squeezing plates can make contact with the tail end of the rod portion of the screw body to be deformed, and the projections of the deformed squeezing plates along the axis of the bolt body cannot fall off onto the end face of the rod portion of the bolt body. The phenomenon that the bolt body retreats from threaded holes of parts is limited through the deformed squeezing plates, and therefore the condition that the bolt body is loosened due to vibration of engineering machines is avoided, and engineering accidents caused by bolt looseness are eliminated completely.

Description

technical field [0001] The invention relates to a bolt, in particular to an anti-loosening bolt for connecting components. Background technique [0002] A bolt is a mechanical part consisting of a head and a screw, and is used to match a threaded hole. Bolts are mainly used to fasten two parts with threaded holes, or cooperate with nuts to connect two parts with through holes. As construction machinery performs related operations, the vibration generated in the motor transmission and the vibration generated during operation will be transmitted to various parts of the construction machinery, and the bolts on the connection parts will be continuously loosened, resulting in instability of the connection parts of the construction machinery. This not only increases the maintenance frequency of construction machinery, but also the bolts are completely loosened, and the related parts fall off, which will cause unnecessary engineering losses. Contents of the invention [0003] T...
