Locking strip for vertical mounting

Abstract

The invention discloses a locking strip for vertical mounting. The locking strip comprises a wedge-shaped fixing groove, a clamping wedge body, a wedge head screw rod, a rotating wedge block and a pulling reed which are connected with each other. The wedge-shaped fixing groove comprises an anti-turning groove body, a lower slope face, a lower skew surface and a lower clamping part. The clamping wedge body comprises a wedge body, an upper slope face, an upper skew surface and an upper clamping part. The wedge head screw rod comprises a screw rod main rod, a wedge head and a double-section thread section. The rotating wedge block comprises a rotating body, a cone wedge face, a mounting hole and a double-section inner thread part. The pulling reed comprises a reed body, a sleeve hole, an upper hook body and a lower hook body. The clamping part is arranged between the wedge-shaped fixing groove and the clamping wedge body. The pulling reed is subjected to sleeving connecting to achieve mutual traction balance between components. When the locking strip is inserted vertically, plate card inserting is not affected. The double-section inner thread part and the double-section thread section are ingeniously used for forming a thread anti-falling structure. An electric tool can carry out quick assembling and disassembling. Working efficiency is improved.

Description

technical field [0001] The invention relates to a locking strip, in particular to a locking strip for vertical installation. Background technique [0002] With the development of science and technology, the design of military equipment is increasingly inclined to miniaturization, integration and modularization. The first problem to be solved by military equipment is the vibration problem. How to ensure that the connection between the module and the motherboard does not fail under the condition of high-speed impact has always been the direction of connector efforts. The emergence of the locking strip as a structural part to improve the seismic strength of the board greatly reduces the difficulty of connector development. Therefore, there are more and more application environments for locking strips, from tanks and armored vehicles to various ships, to civil and military aircraft, to aerospace equipment. [0003] A high degree of integration also requires that the current e...

Problems solved by technology

However, this structure has been found to have many problems in practical applications. One is that the contact area is too small to clamp heavier plates, because the existing locking strips, locking grooves and plate contact surfaces are wedge-shaped slopes at both ends. Side, where the volume of the wedge is relatively small, and the corresponding contact side is also small; the second is that the wedge-shaped slope is used as the positioning surface between the existing wedge and the wedge. When the bolt is in a loose state, the wedge and the wedge The wedges are all easy to rotate relative to the bolts, which can easily cause the positioning surfaces between the wedges and the wedges to not match, and cannot be locked normally; the third is that there is no stable connection between the various parts of the existing locking strips Relationship, each component module is easy to fall when it is in a relaxed state. If the component falls on the PCB board during the disassembly and assembly of the actual application, it is easy to cause short-circuit damage to its components, which also limits the existing locking strip structure. Manual tools can be used, but it is difficult to use electric fast disassembly tools. Some people think of adding anti-drop nuts at the ends of long bolts to achieve electric operation, but this will increase the overall length of the locking bar and cause redundant components. It is cumbersome and inconvenient to use; the fourth is that when the locking strip is inserted in the vertical direction, since there is no mutual traction force between the wedges defined by the positioning surface, the action of gravity will make all the wedges move to their limit positions, which is not suitable for use requirements, and sometimes even get stuck to the edge of the chassis wall, which seriously affects the assembly efficiency
