Fixtures

The present invention provides a fixing device, in particular, a through hole of a sleeve is a positioning rod penetrating with a fixing component and a fixing sleeve sleeved with an elastic element, and the length of the screwing portion of the adjustable positioning rod passes through the sleeve In order to avoid the gap formed between the first plate body and the second plate body, it is impossible to lock into the lock hole, thereby achieving the effects of stable structure and firm assembly.

Pressing, the general panel (board-to-board) is assembled by using a positioning screw with a knob, a collar and a screw to fix the screw and the collar to the first panel, and to rotate The knob is used to lock the screw into the second panel to form a preset position, and then the hand tool is used to lock the screw, so that the first panel and the second panel are locked and fixed into one body, and can be used in a telecom cabinet, an industrial computer. The working machine and the like use a device composed of a plurality of devices and a mechanism to be used for board-to-board connection.

Furthermore, some manufacturers have developed another positioning device that allows the user to use the hand tool to fix or separate the board to the board. Please refer to the figure IX, as can be clearly seen from the figure. A is inserted into the screw A1 with the nut A11, and an elastic body B is sleeved on the screw A1, so that the cap A and the elastic body B can be assembled on the joint C and the inside of the cap A is The hook A2 is fastened to the flange C1 at the top end of the joint C, whereby the cap A, the elastic body B and the joint C can be formed into a positioning device D, and the bottom end of the joint C is clamped C2. After being embedded and fixed in the positioning plate body E, the screw A1 in the cap A can be locked into the fixed plate body E1 by using a hand tool (such as a screwdriver or a wrench), thereby achieving the lock fixing plate body E and the fixing plate. For the purpose of the body E1, and after the fixed plate body E1 is removed, the positioning device D can still be fixed in the positioning plate body E by the joint C without loss.

Due to the increasing popularity of equipment such as cabinets, industrial computers, and work machines in today's telecommunications bureaus, there are often some manufacturing tolerances between the positioning plate body E of the chassis and the fixed plate body E1 of the cabinet. After the screw A1 of the positioning device D cap A on the E side is locked in the fixed plate body E1, the other side of the positioning plate body E will not be able to abut against the fixed plate body E1 to form a gap. And the screw A1 of the positioning device D at the other side of the positioning plate body E cannot be smoothly locked in the fixed plate body E1, or the locking depth of the screw A1 of the second positioning device D is different, and the positioning plate body E is subjected to an external force. When it is affected, the fixed plate body E1 is liable to cause structural damage or deformation, and even the excessive shear force caused by the mis-drawing causes the screw A1 to have a broken or broken condition, and the overall structural stability is also poor, that is, to be engaged in this. The industry is eager to study the key to improvement.

Therefore, in view of the above-mentioned problems and deficiencies, the new creators have collected and collected relevant data through various evaluations and considerations, and have used the trial and modification of many years of research and development experience in this industry to design a new type of such fixed device.

The main purpose of the present invention is that the bottom of the sleeve has a positioning portion positioned at the hole of the first plate body, and a positioning rod with a fixing component is inserted into the through hole of the sleeve and coupled to the positioning rod. a fixing sleeve, and the fixing sleeve is provided with an elastic member located in the receiving groove of the top of the perforation, and the positioning rod has a perforation of the sleeve at the bottom of the head and is locked a screwing portion in the locking hole of the second plate body, wherein the bottom of the fixing hole of the fixing sleeve is formed with an annular blocking portion abutting against the surface of the second plate body, and the annular blocking portion is formed to resist the receiving groove phase An annular abutting portion adjacent to the perforation forms an abutting surface for stopping the positioning. The fixing assembly adjusts the length of the screwing portion of the positioning rod through the perforation of the sleeve to avoid the screwing portion due to the first plate. The gap formed between the body and the second plate body cannot be locked into the lock hole of the second plate body, thereby achieving the effects of stable structure, firm assembly and accurate positioning.
