Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a slotted nut with an anti-falling function. Background Art

[0002] The slot nut is a fastener whose main function is to increase the vibration strength during threaded connection. The working principle of the slot nut is to use the friction between the bolt and the nut to prevent loosening. It has the advantage of easy installation and is suitable for some situations where the position of the bolt and nut is inconvenient to use other fasteners. It can be widely used in the fields of machinery and engineering. However, the current slot nuts still have the following shortcomings:

[0003] For example, the patent document with application number 202221446333.3 discloses a slot nut with an anti-falling function. The slot nut with an anti-falling function pushes the slider backwards to move the magnet backwards and magnetically attract the connecting block. The slider will hold the first screw rod against the first screw rod, so that the first screw rod cannot rotate at will. In this way, the first screw rod can be firmly fixed to prevent the first screw rod from rotating due to external force. The fixing effect is good, but the connection between the nut and the stud is not stable enough and is prone to falling off.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a slot nut with an anti-falling function is proposed. Utility Model Content

[0005] The utility model aims to provide a slot nut with an anti-falling function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a slot nut with an anti-falling function, comprising a hexagonal nut and a reinforcement component, a fixed slot is provided at the upper end of the surface of the hexagonal nut, the reinforcement component is arranged on the surface of the hexagonal nut, and the reinforcement component comprises a fixing rod, a pressing piece, a cross fixing groove, a mortise column and a mortise groove, the fixing rod is slidably connected to the surface of the hexagonal nut, and the inner end of the fixing rod is arranged on the inner side of the hexagonal nut, and two groups of fixing rods are symmetrically arranged, a pressing piece is installed at the outer end of the fixing rod, and a cross fixing groove is provided on the outer surface of the pressing piece, a mortise column is installed on the inner surface of the pressing piece, a mortise groove is provided on the surface of the hexagonal nut, and the inner side of the mortise groove is engaged and connected with the outer surface of the mortise column.

[0015] 1. The utility model is provided with a reinforcement component, which includes a fixing rod, a pressing piece, a cross fixing groove, a mortise column and a mortise groove. The reinforcement component also includes a magnetic attraction layer and an internal thread fixing piece. When in use, after the hexagonal nut is fixed on the stud, the pressing piece is pressed inwardly, so that the pressing piece drives the fixing rod to slide inward along the surface of the hexagonal nut, and further drives the internal thread fixing piece to fix the stud, until the pressing piece drives the mortise column to move to engage with the mortise groove. The magnetic attraction of the magnetic attraction layer will make the connection between the mortise column and the mortise groove more firm, thereby making the connection between the nut and the stud more stable and not easy to fall off.

[0016] 2. The utility model provides a fastening assembly, which includes a receiving groove, a return spring and a connecting rod. The fastening assembly also includes an annular washer and a connecting groove.

[0024] The specific operation is as follows. When in use, after the hexagonal nut 1 is fixed on the stud, the pressing piece 302 is pressed inwardly, so that the pressing piece 302 drives the fixing rod 301 to slide inwardly along the surface of the hexagonal nut 1, and further drives the internal thread fixing piece 307 to fix the stud, until the pressing piece 302 drives the mortise column 304 to move to engage with the mortise groove 305. The magnetic effect of the magnetic layer 306 will make the connection between the mortise column 304 and the mortise groove 305 more firmly.

[0025] Please refer to Figures 2 to 4 The reinforcement component 3 also includes a magnetic layer 306 and an internal thread fixing part 307, and the outer surface of the tenon column 304 and the inner surface of the tenon groove 305 are provided with a magnetic layer 306, the inner end of the fixing rod 301 is installed with an internal thread fixing part 307, the inner surface of the hexagonal nut 1 is provided with a waterproof membrane 5, and the outer surface of the hexagonal nut 1 is provided with a PVD hard coating 6, and the upper surface of the hexagonal nut 1 is provided with a sealing gasket 7, and the sealing gasket 7 is a waterproof silicone structure;

The sealing gasket 7 can also further reduce the infiltration of water. The PVD hard coating 6 has high toughness and anti-wear effects, which can improve the anti-wear performance of the hexagonal nut 1.

[0027] Please refer to Figure 1 The hexagonal nut 1 is a carbon steel structure as a whole, and a fastening assembly 4 for close connection is provided on the surface of the hexagonal nut 1, the fastening assembly 4 includes a receiving groove 401, a return spring 402 and a connecting rod 403, and the receiving groove 401 is provided on the lower surface of the hexagonal nut 1, and a return spring 402 is installed on the upper surface of the inner side of the receiving groove 401, and a connecting rod 403 is provided at the lower end of the return spring 402, the fastening assembly 4 also includes an annular washer 404 and a connecting groove 405, and an annular washer 404 is provided on the lower surface of the hexagonal nut 1, and a connecting groove 405 is provided on the upper surface of the annular washer 404, and the connecting rod 403 is an elastic rubber structure, and the lower end of the connecting rod 403 is engaged and connected with the inner side of the connecting groove 405;

After the fixation is completed, the pressure on the annular washer 404 is limited and stable, and the reset spring 402 itself has a rebound force. The rebound force of the reset spring 402 can drive the connecting rod 403 to move downward, squeezing the annular washer 404 outward, so that the annular washer 404 can make the connection between the hexagonal nut 1 and the fixed position tighter and reduce the gap.

[0029] In summary, if Figures 1 to 4As shown, the slot nut with anti-falling function is used. First, when the hexagonal nut 1 is fixed, the annular washer 404 will be squeezed, driving the connecting rod 403 to slide upward along the inner side of the accommodating groove 401, so that the reset spring 402 is compressed. After the fixing is completed, the pressure on the annular washer 404 is limited and stable, and the reset spring 402 itself has a rebound force. The rebound force of the reset spring 402 can drive the connecting rod 403 to move downward, and squeeze the annular washer 404 outward, so that the annular washer 404 can make the connection between the hexagonal nut 1 and the fixed position tighter and reduce the gap. After the hexagonal nut 1 is fixed on the stud, press the button inward. The pressing piece 302 drives the fixing rod 301 to slide inward along the surface of the hexagonal nut 1, and further drives the internal thread fixing piece 307 to fix the stud, until the pressing piece 302 drives the mortise column 304 to move to engage with the mortise groove 305. The magnetic attraction of the magnetic layer 306 will make the connection between the mortise column 304 and the mortise groove 305 more firmly. During the use of the device, the waterproof membrane 5 can improve the waterproof effect of the connection surface between the hexagonal nut 1 and the stud, and it is not easy to rust. The sealing gasket 7 can also further reduce the infiltration of water. The PVD hard coating 6 has high toughness and wear resistance, which can improve the wear resistance of the hexagonal nut 1.
