Description

Technical Field

[0001] The utility model relates to the technical field of pressure riveted nut columns, in particular to a pressure riveted nut column with an anti-loosening structure. Background Art

[0002] A pressure riveted nut standoff, also known as a pressure riveted stud or nut standoff, is a fastener used for sheet metal, thin plates, chassis, and cabinets. The pressure riveted nut standoff has a hexagonal end and a cylindrical end. There is a backslash between the hexagonal side and the cylindrical shape, and its inner shape is an internal thread. The hexagonal head is pressed into the preset hole of the thin plate by a press (the aperture of the preset hole is generally slightly larger than the cylindrical outer diameter of the pressure riveted stud), causing plastic deformation around the hole. The deformed part is squeezed into the backslash of the pressure riveted nut standoff, so that the pressure riveted nut standoff is riveted to the thin plate, thereby forming an effectively fixed internal thread on the thin plate.

DETAILED DESCRIPTION

[0030] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0031] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

The screw body 2 is threadedly matched with the nut column body 1. An anti-loosening structure is provided on the nut column body 1.

The bottom of the nut column body 2 is fixedly connected to the connecting block 1, and the inside of the connecting block 12 is slidably connected to the contact block 121. The contact block 121 is provided with four groups.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example 1:

[0035] In order to solve the problem that the existing self-clinching nut column often has a single structure and only has the function of fixing the screw, and when it is used, it is inevitable that vibration will occur, which easily causes the installed self-clinching nut to loosen, this embodiment discloses the following technical solutions, specifically as follows: Figures 1-6As shown, the inner wall of opening 11 is fixedly connected with spring rod 111, one end of spring rod 111 is fixedly connected with supporting block 112, one side of contact block 121 is fixedly connected with L-shaped rod 122, the inner side of connecting block 12 is provided with a groove for contact block 121 to slide, the inner side of 1 is provided with a groove for L-shaped rod 122 to slide, one side of L-shaped rod 122 is fixedly connected with spring rod 2 123, one end of spring rod 2 123 is fixedly connected to the interior of connecting block 12, the outer side of nut column body 1 is also provided with opening 2 13, opening 2 13 is provided with four groups, one end of L-shaped rod 122 is fixedly connected with pop-up block 131, pop-up block 131 is slidably connected to the interior of opening 2 13, when the nut column body 1 needs to be installed on the plate to be installed, at this time, the nut column body 1 is driven into the interior of the plate using a tool, during the process of driving the nut column body 1 into The setting of the trapezoidal surface of the support block 112 ensures that there will be no mechanical obstruction in the movement of the nut column body 1. When the opening 11 is on the other side of the plate, under the action of the spring rod 111, the support block 112 pops out from the inside of the opening 11, and the support block 112 can play an auxiliary fixing effect. At this time, the screw body 2 can be driven into the inside of the nut column body 1. When the screw body 2 moves, it will pass through the connecting block 12. When the screw body 2 contacts the contact block 121 inside the connecting block 12, the L-shaped rod 122 will move, and then the pop-up block 131 will be moved out from the inside of the opening 2 13. At this time, under the effect of the pop-up block 131 and the support block 112, the nut column body 1 can be stably placed on the plate, thereby preventing the nut column body 1 from loosening from the plate and improving the use effect.

[0036] At the same time, in order to solve the problem that the screw body 2 on the existing pressure riveted nut column often lacks a fixing component when being driven in, and is prone to loosening after long-term use, the present embodiment also discloses the following solution: a trapezoidal block 14 is slidably connected to the connecting block 12, and the trapezoidal block 14 is provided with multiple groups. The bottom of the corresponding trapezoidal block 14 is fixedly connected to a connecting plate 141, and the bottom of the connecting plate 141 is fixedly connected to a spring piece 142, and the other end of the spring piece 142 is fixedly connected to the inside of the connecting block 12, and the bottom end of the screw body 2 is fixedly connected to a transmission block 21, and the top of the transmission block 21 is fixedly connected to a trapezoidal block 211, and the trapezoidal block 211 slides with the trapezoidal block 14. When the screw body 2 is driven into the inside of the nut column body 1, during the process of tightening the screw body 2, at this time The trapezoidal block 211 at the top of the transmission block 21 on the screw body 2 can contact the trapezoidal block 14 and make the trapezoidal block 14 move. The trapezoidal block 14 drives the connecting plate 141 to move, thereby compressing the spring piece 142. When the screw body 2 is screwed to a certain extent and the screw body 2 is fixed, due to the setting of the trapezoidal block 14 and the trapezoidal block 211, the spring piece 142 resets the trapezoidal block 14 and makes the trapezoidal block 14 conflict with the trapezoidal block 2 211. At this time, in the process of using the nut column body 1 in conjunction with the screw body 2, the transmission block 21 cannot rotate due to the mutual conflict between the trapezoidal block 211 and the trapezoidal block 14, thereby effectively avoiding the rotation of the screw body 2 and facilitating use.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
