Technical Field

The application relates to the technical field of fasteners, in particular to a quick-release screw.

Background

The screw is a tool for fastening the parts of the device step by utilizing the physical and mathematical principles of the inclined circular rotation and friction force of the object. The quick-release screw is used as a novel screw structure, so that a machine part of a device can be quickly dismounted, and the operation efficiency is improved.

In the related art, as shown in fig. 1 and 2, a quick-release screw is disclosed, which comprises a screw head 1, a polish rod 2 integrally formed at one side of the screw head 1, a positioning block 3 fixed at one end of the polish rod 2 far away from the screw head 1, and a cross groove 4 is formed in the side wall of the screw head 1 far away from the polish rod 2. The length of the positioning block 3 is larger than the diameter of the polish rod 2, the width of the positioning block 3 is smaller than the length of the positioning block 3, and a positioning boss 5 is formed between the positioning block 3 and the polish rod 2. When the quick-release screw is installed, the positioning block 3 and the polished rod 2 can pass through the through hole on the fixed piece 6, and then the head of the quick-release screw is rotated until the positioning boss 5 is abutted with the inner wall of the fixed piece 6. During disassembly, the cross screwdriver stretches into the cross groove 4, the screw head 1 is rotated and drives the quick-release screw to integrally rotate, the positioning boss 5 is not abutted with the inner wall of the fixed piece 6 any more, and the quick-release screw is moved out of the fixed piece 6, so that the fixed piece 6 is quickly disassembled.

In the process of realizing the related art, the fixed part is usually a non-transparent part, so that an operator cannot see the position state of the positioning boss in the fixed part, and the operator needs to rotate repeatedly to rotate the positioning boss to a state of not abutting against the inner wall of the fixed part any more, so that the operation efficiency is low, and the improvement is needed.

Disclosure of Invention

In order to be able to quickly identify the position state of the positioning boss, the application provides a quick-dismantling screw.

The application provides a quick detach screw adopts following technical scheme:

the utility model provides a quick detach screw, is including the spiral shell head, be located the polished rod of spiral shell head one side, be located the polished rod and keep away from the locating piece of spiral shell head one end, the length of locating piece is greater than the diameter of polished rod, form the location boss between locating piece and the polished rod, the cross groove has been seted up on the lateral wall that the locating piece was kept away from to the spiral shell head, the instruction groove has been seted up on the cell wall of cross groove, the circumference side intercommunication of instruction groove and spiral shell head, the extending direction of instruction groove is on a parallel with the length direction of locating piece.

Through adopting above-mentioned technical scheme, when dismantling quick detach screw, can stretch into the cross recess with the cross screwdriver earlier, rotate the screw head and drive quick detach screw integral rotation. Because the extending direction of the indication groove is parallel to the length direction of the positioning block, an operator can observe the position state of the indication groove, confirm the position state of the positioning boss positioned in the fixed piece until the positioning boss is not abutted with the inner wall of the fixed piece any more, and finally move the positioning block out of the fixed piece to complete the disassembly of the quick-release screw. The setting makes operating personnel can discern the position state of location boss according to the instruction groove fast, need not to relapse rotatory just can shift out the location boss by the mounting many times to realize dismantling by the mounting fast.

In addition, during daily use, operating personnel can confirm whether the location boss is with the diapire butt of being the mounting according to the positional relationship in instruction groove to confirm whether quick detach screw is connected with being the mounting is stable, the convenience is overhauld by the mounting daily.

Optionally, an indication block is arranged on the circumferential side wall of the screw head, and the distribution direction of the indication block and the indication groove is parallel to the axial direction of the screw head.

Through adopting above-mentioned technical scheme, on the one hand, when light is not good be difficult to see clearly the instruction groove, operating personnel can be through the position of staff touch spiral shell head, seek the instruction piece to confirm the position state of location boss.
