Problems solved by technology

[0002] In today's market, the commonly used riveting device is the expansion screw, which expands after the expansion screw is inserted into the wall to achieve the effect of riveting. However, when the expansion screw needs to be taken out, it must be pulled out with a claw hammer or vice, which costs A lot of manpower, and it is not necessarily easy to take it out, and if it is serious, it needs to destroy the wall

Embodiment Construction

[0015] The invention patent will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the wall is drilled in advance, and the threaded shaft 4 is rotated until the stopper 6 is in contact with the inner side of the card slot 1, so that it will not fall out of the card slot, so as to achieve the integrity of the device and avoid inconvenience caused by parts falling off during carrying or installation. The diameter of the through hole is larger than the diameter of the fixed shaft 2, and the riveting piece a3 and the riveting piece b7 can freely rotate in the slot with the fixed shaft 2 as the center. Manually rotate the riveting piece a3 and the riveting piece b7 until the acute angle end closes and overlaps and is in a straight line with the threaded shaft 4, insert the device into the pre-punched hole, insert it to the limit position and start to twist the threaded shaft 4, Ning to the limit position, after the thre...

Abstract

The invention discloses a double-sheet riveting device. A threaded shaft is rotated until blocking pieces make contact with the inner side of a clamping groove. The blocking pieces cannot come out of the clamping groove. Integration of the device is realized. Inconvenience caused by part fall-off in the carrying or mounting process is avoided. The diameter of through holes is greater than that of a fixed shaft. A riveting sheet a and a riveting sheet b can rotate freely in the clamping groove with the fixed shaft as the circle center. The riveting sheet a and the riveting sheet b are manually rotated until the acute-angle ends of the riveting sheet a and the riveting sheet b are closed and overlapped and form a straight line with the threaded shaft. After the device is inserted into a pre-drilled hole to a limit position, the threaded shaft starts to be rotated to the limit position. The threaded shaft applies force to the riveting sheet a and the riveting sheet b. Because of direction deflection of force, the long axes of the riveting sheet a and the riveting sheet b get close to the horizontal direction. As the threaded shaft is in threaded connection with the clamping groove, traditional nut fixation is replaced, the steps are decreased, and accordingly the labor cost is lowered.

Description

technical field [0001] The patent of the present invention relates to a riveting device, in particular to a riveting device that is easy to insert into a wall and easy to take out, and also improves the load-bearing capacity. Background technique [0002] In today's market, the commonly used riveting device is the expansion screw, which expands after the expansion screw is inserted into the wall to achieve the effect of riveting. However, when the expansion screw needs to be taken out, it must be pulled out with a claw hammer or vice, which costs a lot of money. A lot of manpower is required, and it is not necessarily easy to take it out. In severe cases, the wall needs to be destroyed. Contents of the invention [0003] In order to solve the above problems, the patent of the present invention provides a riveting device that is easy to insert into the wall and easy to take out, and also improves the load-bearing capacity. [0004] A double-piece riveting device, character...
