Abstract

The invention provides a pulling assisting device and relates to the technical field of case equipment. The pulling assisting device solves the technical problem that a self-locking part is independent from a pulling assisting device body and is large in occupied space and complex to install. The pulling assisting device comprises a pulling assisting block, a pulling assisting body, a pulling assisting clamping block and a compression spring. The bottom of the pulling assisting body is rotationally connected with the pulling assisting block. A containing cavity is formed in the pulling assisting body. The pulling assisting clamping block can be rotationally arranged in the containing cavity. The compression spring is located on the bottom side of the pulling assisting clamping block. The pulling assisting clamping block and the compression spring are reasonably arranged in the pulling assisting body so that the occupied space can be greatly reduced; and the self-locking action can be automatically completed when the pulling assisting body reaches the limit position, and locking can be completed instantly only by pressing the head of the pulling assisting clamping block. Operation is simple and obvious and can be completed with the single hand, the operation is simplified, and the operation is very convenient.

Description

technical field [0001] The invention relates to the technical field of cabinet equipment, in particular to a self-locking extractor. Background technique [0002] As we all know, in many fields such as communication and electronics, various types of chassis equipment are widely used. When a single board is connected to a backplane (usually referred to as a circuit board) in these chassis devices, the connection mode generally adopted is single-board docking. However, there is a certain resistance in this connection method, and the insertion and extraction force is relatively large, so it is difficult to operate with bare hands. For the convenience of operation, it is necessary to use a puller. [0003] With the development of electronic technology, the requirements for electronic equipment are getting higher and higher. If the puller is loose during use, it will affect the transmission of the signal, and the device will not work normally; Puller to make up for the unreliab...
