Abstract

The invention discloses a screw connecting structure, which comprises a screw for connecting first equipment with second equipment and a transition piece; the screw passes through the first device and then is connected with a transition piece fixed on the second device. The traditional screw connection structure is improved, the transition piece is arranged as a connection medium of the screw connection, when the screw is broken, the effect of quickly taking out the broken screw can be realized by taking out the transition piece, and the transition piece is simpler and more convenient to take out than the broken screw which is directly taken out, so that the quick recovery of the screw connection can be realized; the labor and time cost are saved, the operation rate of the equipment is improved, and the precision of the equipment is ensured.

Description

Screw connection structure

Technical Field

The invention relates to the technical field of mechanical equipment, in particular to a screw connection structure.

Background

The screw connection is a common connection mode in mechanical equipment and is widely applied to various mechanical equipment. Because mechanical equipment is easily influenced by external factors or impact load in the use process, the screw can be broken, once the screw is broken, the thread section of the screw can be clamped in a threaded hole of a base, the diameter of the screw is generally small, the broken screw is difficult to take out, the possibility of damaging the thread of the base exists, if the thread of the base is damaged, the base needs to be subjected to repair welding again, drilling and tapping, the repair time slice field of the equipment can be undoubtedly caused, the maintenance cost is increased, the thermal deformation of the equipment base is easily caused in the repair welding process, and the precision of the equipment is seriously influenced.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: provided is a screw connection structure which can quickly restore screw connection after a screw is broken.

In order to solve the technical problems, the invention adopts the technical scheme that: the screw connecting structure comprises a screw for connecting the first equipment with the second equipment and a transition piece; the screw passes through the first device and then is connected with a transition piece fixed on the second device.

Further, the method comprises the following steps: the transition piece is a sleeve ring structure with threads on the outer surface and the inner hole surface, and the second equipment is provided with a fixing hole matched with the threads of the transition piece; the screw is in threaded connection with the inner bore surface of the transition piece.

Further, the method comprises the following steps: the bottom surface of the fixing hole is an inwards concave arc-shaped surface.

The invention has the beneficial effects that: the traditional screw connection structure is improved, the transition piece is arranged as a connection medium of the screw connection, when the screw is broken, the effect of quickly taking out the broken screw can be realized by taking out the transition piece, and the transition piece is simpler and more convenient to take out than the broken screw which is directly taken out, so that the quick recovery of the screw connection can be realized; the labor and time cost are saved, the operation rate of the equipment is improved, and the precision of the equipment is ensured.

Drawings

FIG. 1 is a cross-sectional view of the structure of the present invention;

labeled as: 100-first device, 200-second device, 210-fixation hole, 300-screw, 400-transition piece.

Detailed Description

In order to facilitate understanding of the invention, the invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, the screw connection structure according to the present invention is used for connecting and fixing two devices. The traditional screw connection is characterized in that a screw is directly connected with a threaded hole arranged on equipment, when the screw is broken due to external factors or impact load, because the size of the screw is small, the screw broken in the threaded hole is difficult to take out, and the equipment is easy to damage. The transition piece 400 is fixed in the fixing hole 210 through a threaded connection, the screw 300 is threaded with the transition piece 400 after passing through the first device 100, and the first device 100 is connected and fixed with the second device 200 through the fastening action of the screw 300. After the transition piece 400 is added, if the screw 300 is broken, the broken section of the screw 300 is positioned in the transition piece 400, a maintenance worker does not need to directly take out the broken section of the screw 300, but can take out the broken section of the screw 300 by removing the transition piece 400, because the size of the transition piece 400 is far larger than that of the screw 300, the screw 300 can be taken out conveniently, a rotating shaft can be welded on the transition piece 400, the transition piece 400 is screwed out of the fixing hole 210 by rotating the rotating shaft, the broken section of the screw 300 is removed after the transition piece 400 is taken out of the equipment, or the transition piece 400 is directly selected to be replaced, so that the quick recovery of the screw connection can be realized, and the equipment cannot be damaged.

As shown in fig. 1, the bottom of the fixing hole 210 is a concave arc surface, the depth of the center of the bottom of the fixing hole 210 is higher than the depth of the edge by arranging the arc surface, an abdicating space is provided for the connected screw 300, and the end of the screw 300 can be screwed out of the bottom surface of the transition piece 400, so that after the transition piece 400 is taken out, the exposed end of the screw 300 can be clamped, and a maintenance worker can conveniently take out the broken section of the screw 300.
