Abstract

The present invention relates to a fixing device. The fixing device is provided with a positioning part below the perforation of the sleeve, and a ring groove is provided above the adjacent positioning part for setting a stop washer, and the perforation of the sleeve penetrates a fixed The shaft and the threaded part extending from the bottom surface of the head of the element, and the head of the fixed element is combined with an outer sleeve, and a ring-shaped support body is provided under the storage space in the outer sleeve, so that the screwed part of the fixed element can be linked After the elastic deformation and reset process, the ring-shaped abutting body of the outer sleeve is abutted against the stop washer of the sleeve to form a movable socket, and the actuating part and the pulling part arranged outside the outer sleeve can be used for hand tools. Drive the actuating part or manipulate the wrenching part with bare hands, and rotate the outer sleeve to lock or unlock the fixing element between the first board and the second board, so as to facilitate board-to-board locking.

Description

technical field [0001] The invention relates to a fixing device, especially a fixing device that can be easily rotated and locked or unlocked by hand tools or manual operation. A fixing element is inserted inside the sleeve, and an outer casing is assembled outside the head, and the outside of the outer casing is used to There is an actuating part and a wrenching part, which can be operated by hand tools or by bare hands, so as to facilitate the operation of the fixing device. Background technique [0002] When assembling general panels (board-to-board), lock them with positioning screws equipped with knobs, collars and screws, then fix the screws and collars on the first panel, and turn the knobs to make the screws In order to lock into the second panel to form a preset position, and then use hand tools to lock the screws, so that the first panel and the second panel are locked and fixed as one, and can be used in telecom bureau cabinets, industrial computers, and working m...

Problems solved by technology

[0006] However, the flange E1 of the sleeve E is embedded in the slot F21 of the screw section F2 of the locking unit F, and its threaded section F3 will protrude out of the sleeve E and the plate G. When the plate G When the lower cover is closed on the base H, the deflection displacement of the panel G is often caused by the collision of the threaded section F3 of the locking unit F on the base H, so that the threaded section F3 cannot be laterally locked on the base H accurately. Structural damage or damage, and due to the increasing use of industrial computers, work machines and other equipment, connectors are usually provided on the board G and base H of the case. When the board G covers the base H After being connected, the connectors can be mated and docked. However, if the board G is deflected or skewed, the alignment between the connectors will not be possible, and even the collision will cause structural damage and affect the Stability of the overall signal transmission; Moreover, when the locking unit F intends to lock the plate G and the base H, the actuating groove F11 on the force-bearing part F1 is locked by a mechanical tool of an electric screwdriver, and The locking force of the electric screwdriver is strong, and the locking force cannot be controlled during operation. If the locking unit F is installed behind the plate G and the base H, it is easy to drive the locking unit F over-locked due to excessive force of the electric tool. If the threaded section F3 of the locking unit F is inserted into the base, the teeth of the threaded section F3 of the locking unit F are often broken or broken; if the plate G and the base H are to be disassembled, the locking unit F cannot be rotated by hand, and electric tools must be used. To operate the locking unit F, and the electric screwdriver is a special mechanical tool, which cannot be easily obtained, so that the subsequent disassembly or reassembly of the panel G and the base H must rely on the electric screwdriver, resulting in a great deal of work trouble and inconvenience

[0007] Therefore, how to solve the problems and troubles of the current panel locking and screwing components, because the cap head is not easy to hold and rotate with bare hands, and some locking units are locked mechanically, which also causes many inconveniences and defects in the operation. , which is the direction for the relevant manufacturers engaged in this industry to study and improve
