Single-sheet type riveting device

Abstract

The invention discloses a single-sheet type riveting device. A threaded shaft is rotated to a stop piece to be in contact with the inner side of a clamping groove and does not fall off from the clamping groove, and therefore the integrity of the device can be realized, and inconvenience caused by part falling-off in the carrying or installing process can be avoided. The two ends of the long axis of a riveting sheet are respectively of an arc shape so that the riveting sheet can be inserted into a wall or taken out from the wall conveniently, the long axis of the riveting sheet is close to the horizontal direction due to deflection of the force direction after the threaded shaft exerts force on the riveting sheet, at this time a spacer is pushed to make contact with the clamping groove, a nut is rotated to make contact with the spacer and then is screwed to a limit position, and the spacer can effectively prevent the phenomenon of slipping when the rotary force is too large. The position of the threaded shaft can be firmly fixed through the nut, and the phenomenon that the device is not firm because the threaded shaft loosens can be prevented. Operating personnel exert force in a hand holding area in use, the hand holding area is of a grid structure or a frosted structure, the friction force can be increased, and therefore the human cost can be 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 the wall and take out, and also improves the pull-out resistance and load-bearing capacity. Background technique [0002] In today's market, the commonly used riveting device is expansion screw. After the expansion screw is inserted into the wall, the mechanical expansion rate is about 20%-30%, which achieves the effect of riveting. When removing the expansion screw from a relatively loose wall, it must be Pulling out with a claw hammer or a vise is labor-intensive, and it is not necessarily removed. If the wall is concrete or solid brick, it cannot be taken out at all, and you must use a cutting tool or break the wall to take it out. SUMMARY 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 ou...
