Wedge locker adopting forward and reverse thread transmission locking manner

Abstract

The invention discloses a wedge locker adopting a forward and reverse thread transmission locking manner. The wedge locker comprises a main groove body, an anti-disengaging block, a screw, a fixed wedge block and a movable wedge block set. The fixed wedge block is fixedly connected to one end of the length direction of the main groove body, the movable wedge block set is connected to the length direction of the main groove body, and one end of the movable wedge block set cooperates with the fixed wedge block. The anti-disengaging block is fixedly connected to the other end of the length direction of the main groove body, and the screw is in threaded connection with the anti-disengaging block and the movable wedge block set simultaneously. The screw comprises two sections of threads, one section of thread is a right-handed rotation forward thread, the other section of thread is a left-handed rotation reverse thread, and the movable wedge block set and the anti-disengaging block are provided with right-handed rotation forward threads or left-handed rotation reverse threads corresponding to the position of the screw. Two-stage anti-disengaging design is adopted, so that the potentialsafety hazard caused by the fact that the screw disengages from a part to be scattered is completely eradicated; the operation is more direct due to locking design and reduction of the rotation frequency; and the application range of the wedge locker is also greatly widened due to breakthrough of the rising height.

Problems solved by technology

[0002] As electronic equipment, especially military electronic equipment, is more and more widely used, its environment is becoming more and more complex and harsh. In order to improve combat effectiveness, military electronic equipment has been developing towards modularization, miniaturization, and high integration. It has brought a series of problems such as high heat flux density, difficult heat dissipation, and inconvenient maintenance.

The wedge locker plays a vital role as a product for reliable locking of each module in the equipment and effective heat conduction. It has laid a solid foundation for equipment modularization, miniaturization, and high integration, and has become an indispensable important part. One, but there are still many deficiencies and problems in the wedge lockers currently on the market, which cannot effectively meet the development trend of military equipment, which not only greatly limits the reliability and maintainability of the equipment, but often requires a huge amount of money to solve these problems The energy and cost of the equipment have seriously affected the combat effectiveness of the equipment

[0003] When the positive wire thread lock is disassembled after the module is locked, there is often the problem that the wedge block is stuck and cannot be retracted. Some wedge lockers with reed springback cannot fundamentally solve this problem due to their weak force

[0004] The first-level thread structure currently used in the market cannot fully guarantee that the screw will not come out when the wedge locker is loosened and retreated. Once the wedge locker is released, the locking will fail, and the parts scattered inside the device will cause a short circuit, causing a slight damage to the device. Personal safety, there is a great security risk

[0005] Due to the small size of the wedge locker, the normal thread of M3 and below is generally used, and its pitch is small. In order to achieve the required rising height, it needs to rotate a lot of turns, which limits the range of rising height and adapts to the equipment. The scope of requirements is relatively narrow, and the user experience is not good
