Anti-lost bolt dismounting device

Abstract

The invention discloses an anti-lost bolt dismounting device. The anti-lost bolt dismounting device comprises an upper shell body and a lower shell body; the upper shell body is provided with a via hole, and the lower shell body is provided with a connecting sleeve corresponding to the position of the via hole, the connecting sleeve comprises a threaded chamber arranged on the lower side and a containing chamber arranged on the upper side; the outer diameter of the containing chamber is larger than the outer diameter of the threaded chamber; a bolt is installed in the via hole; and the outer diameter of the lower middle part of the bolt is matched with the cavity inner diameter of the threaded cavity, and corresponding threaded part are arranged. According to anti-lost bolt dismounting device, a horizontal clamping block is subjected to be clamped in an annular groove through the natural installing of the bolt, using is convenient during installing, and redundant operations are avoided; and the bolt is prevented from being lost under the action of the horizontal clamping block when the upper shell body and the lower shell body are dismounted, finally the bolt can be removed from the shell bodies by pulling of external force, the bolt can be removed from the shell bodies, functions in three areas are realized, and great convenience is achieved.

Description

technical field [0001] The invention relates to equipment components, in particular to an anti-lost screw dismounting device. Background technique [0002] In all kinds of component equipment, it is necessary to continue to maintain the components. Most of the existing equipment connection and fixing methods are fixed by screws and threads. In the maintenance, it is usually necessary to remove the screws before the maintenance can be performed. In the existing The screw installation structure in the equipment needs to be completely disassembled, and the upper and lower shells are completely separated, which can easily lead to a problem that the screws are easy to lose, which will have a great impact on the work; in the public patent document with the publication number: CN204431195U, a An anti-lost screw removal device can achieve the purpose of anti-lost screws, but the disadvantage of this structure is that the threaded part is placed in the receiving cavity after the scre...

[0002] In all kinds of component equipment, it is necessary to continue to maintain the components. Most of the existing equipment connection and fixing methods are fixed by screws and threads. In the maintenance, it is usually necessary to remove the screws before the maintenance can be performed. In the existing The screw installation structure in the equipment needs to be completely disassembled, and the upper and lower shells are completely separated, which can easily lead to a problem that the screws are easy to lose, which will have a great impact on the work; in the public patent document with the publication number: CN204431195U, a An anti-lost screw removal device can achieve the purpose of anti-lost screws, but the disadvantage of this structure is that the threaded part of the screw is placed in the receiving cavity after the screw is moved up, and it is not completely disassembled; but in actual use, the screw is not Any restraint, it is still very likely that the upper and lower shells will fall off, resulting in lost screws
