Abstract
The pin connection is a common engineering structure connection mode. The conventional pin shaft generally needs to be punched on the main pin shaft and then inserted with a bolt, the installation mode is complex in operation, and the pin shaft head has a sharp protruding part after installation, so that people are easily collided, and potential safety hazards exist. The utility model relates to a structure lock catch pin shaft, which comprises a pin body, a fixed end, a pin head, a lock hole, a lock ball, a lock core thread, a lock head and a wrench groove; the pin body is provided with the fixed end, a pin head and a lock hole, a lock ball is arranged in the lock hole, and a lock cylinder thread, a lock head and a wrench groove are arranged on the lock cylinder. Compared with the conventional pin shaft, the utility model discloses need not punch at the main part round pin epaxial and add the bolt, simplified installation operating procedure, eliminated the potential safety hazard, improved the work efficiency and the security performance of structrual installation.
Description
Technical Field
The invention belongs to the technical field of machinery, and relates to a structural lock catch pin shaft.
Background
The pin connection is a common engineering structure connection mode. The conventional pin shaft generally needs to be punched on the main pin shaft and then inserted with a bolt, the installation mode is complex in operation, and the head of the pin shaft is provided with a sharp protruding part after installation, so that people are easily knocked to the pin shaft, and potential safety hazards exist. Therefore, in order to facilitate the installation and the disassembly of the engineering structure, a novel structure lock pin shaft needs to be developed.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a lock catch pin shaft for mounting and dismounting an engineering structure.
According to the technical scheme provided by the invention: the structure lock catch pin shaft comprises a pin body, a fixed end, a pin head, a lock hole, a lock ball, a lock core thread, a lock head and a wrench groove; the lock comprises a lock body, a lock core, a lock head, a lock hole, a lock core thread, a lock head and a wrench groove, wherein the lock body is provided with the fixed end, the lock head and the lock hole, the lock ball is arranged in the lock hole, the inner diameter of the lock hole is larger than the outer diameter of the lock ball, the lock ball can move in the lock hole but cannot fall outwards, the lock core is provided with the lock core thread, the lock head and the wrench groove, the lock core is connected with an inner hole of the lock head through the lock core thread, and the lock core can be pushed to move axially by.
The invention has the advantages that: compared with the conventional pin shaft, the main body pin shaft does not need to be punched and then inserted with a bolt, so that the installation operation procedure is simplified, the head part of the pin shaft does not have an external protrusion after installation, and the potential safety hazard is eliminated. The invention is convenient to mount and dismount, and improves the working efficiency and safety performance of structural mounting.

Detailed Description
The invention is further illustrated by the following specific figures and examples.
As shown in fig. 1: the invention mainly comprises a pin body 1, a fixed end 2, a pin head 3, a lock hole 4, a lock bead 5, a lock core 6, a lock core thread 7, a lock head 8 and a wrench groove 9; the lock pin comprises a pin body 1, a fixed end 2, a pin head 3 and a lock hole 4, wherein a lock ball 5 is arranged in the lock hole 4, the inner diameter of the lock hole 4 is larger than the outer diameter of the lock ball 5, so that the lock ball 5 can move outwards in the lock hole 4 for a certain distance and cannot fall off outwards, a lock cylinder thread 7, a lock head 8 and a wrench groove 9 are arranged on a lock cylinder 6, the lock cylinder 6 is connected with an inner hole of the pin head 3 through the lock cylinder thread 7, and the lock cylinder 6 can be pushed to move axially by rotating the lock cylinder 6 after being aligned with the wrench groove 9 through a special wrench.
In particular, as shown in fig. 1-3. During installation, the lock core 6 is axially moved outwards by rotating counterclockwise after the special spanner is aligned with the spanner groove 9, and when the inclined surface of the lock head 8 leaves the lock hole 4, the lock balls 5 fall into the lock hole 4, so that the pin body 1 is in an installation state (see fig. 1); then the pin body 1 passes through a connecting hole of a component needing to be locked, the lock hole 4 and the lock ball 5 completely pass through the connecting hole, then the lock core 6 is rotated clockwise after a special wrench is aligned with the wrench groove 9, so that the lock core 6 moves inwards along the axial direction, and the lock ball 5 moves outwards to protrude out of the pin body 1 to be locked in the connecting hole of the component needing to be locked under the extrusion of the inclined surface of the lock head 8 (see figure 3), thereby achieving the purpose of locking the connecting component.
