Description

Technical Field

[0002] Nuts are nuts that are screwed together with bolts or screws to tighten. They are a must-have component for all manufacturing machinery. They are divided into several types, such as carbon steel, stainless steel, and nonferrous metals (such as copper), according to different materials. Their working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking.

[0003] The utility model with the authorization announcement number CN206738363U retrieved relates to an anti-heel-rotation expansion rivet structure, including a fastening thin plate, a reserved hole set on the fastening thin plate, and an expansion rivet nut tightened on the reserved hole. The reserved hole is a circular through hole. The expansion rivet nut includes a cylindrical expansion rivet head and a fastening nut connected to the tail of the expansion rivet head. The fastening nut and the expansion rivet head are integrated. A notch is provided at the edge of the reserved hole. The expansion rivet head passes through the reserved hole. The part of the expansion rivet head head exposed on the top surface of the fastening thin plate is bent outward. The outer wall material of the expansion rivet head is squeezed into the notch. One end of the fastening nut connected to the expansion rivet head is fitted with the bottom surface of the fastening thin plate, that is, the fastening thin plate is sandwiched between the expansion rivet head head and the fastening nut. The utility model sets a notch at the edge of the reserved hole to facilitate the expansion rivet head head to squeeze into the notch, significantly improves the torsion resistance of the expansion rivet nut, has a simple structure, and is easy to process.

[0028] A nut with a screw connection structure comprises: a bolt body 1, a connecting nut 2 and a fixing nut 3 are arranged on the surface of the bolt body 1, a fixing column 9 is movably connected to the bottom surface of the fixing nut 3, a second fixing hole 10 is opened on the upper surface of the connecting nut 2, a nylon ring 8 is fixedly connected to the top of the connecting nut 2, the connecting nut 2 and the fixing nut 3 are connected via the fixing column 9 and the second fixing hole 10, a first fixing hole 6 is opened on the surface of the connecting nut 2 and the fixing nut 3, a connecting sheet 4 is arranged on one side of the first fixing hole 6, and a fixing bolt 5 is movably connected to the surface of the connecting sheet 4.

[0029] In a specific embodiment of the utility model, through the coordinated use of the connecting nut 2 and the fixing nut 3, the connection between the bolt body 1 and the connecting nut 2 can be strengthened, and the stability during use can be increased, thereby avoiding the defects of the current solution in terms of the fixing and anti-slip performance of the nut. After long-term use, the nut is prone to loosening and slipping, and cannot be locked with the bolt, thereby improving the stability of the nut with a screw connection structure.

[0030] Specifically, the connecting nut 2 includes a nut body 201, a plug-in column 202, an internal thread ring 203 and a connecting hole 204. The nut body 201 is arranged on the surface of the bolt body 1, the internal thread ring 203 is opened at the center of the nut body 201, the connecting hole 204 is opened on the side of the nut body 201, and the plug-in column 202 is movably connected to the inside of the connecting hole 204.

[0031] In a specific embodiment of the present invention, the provision of the internal thread ring 203 enables the connecting nut 2 to be easily and quickly disassembled and connected from the surface of the bolt body 1, thereby improving the convenience of the nut with a threaded structure.

[0032] Specifically, there are two fixing columns 9 , which are symmetrically arranged on both sides of the fixing nut 3 .

[0033] In a specific embodiment of the present invention, the provision of the fixing column 9 and the second fixing hole 10 strengthens the connection between the connecting nut 2 and the fixing nut 3, thereby improving the stability of the nut with a threaded structure.

[0034] Specifically, a plug hole 7 is opened on the surface of the bolt body 1 , and the connecting nut 2 is movably connected to the bolt body 1 through the plug hole 7 and the plug column 202 .

[0035] In a specific embodiment of the present invention, the connection between the insertion hole 7 and the insertion column 202 enables the bolt body 1 and the connecting nut 2 to be stably connected to avoid slipping, thereby improving the practicality of the nut with a threaded structure.

[0036] Specifically, one end of the plug-in post 202 is designed as a bevel, and the inner shape of the plug-in hole 7 is consistent with the plug-in post 202 .

[0037] In a specific embodiment of the present invention, the inclined surface design of the plug-in column 202 increases the friction between the bolt body 1 and the connecting nut 2, thereby further improving the stability of the nut with a threaded structure.

[0038] Specifically, the connecting sheet 4 is a metal stainless steel sheet, and a through hole movably connected to the fixing bolt 5 is opened on the surface of the connecting sheet 4 .

[0039] In a specific embodiment of the utility model, the provision of the connecting sheet 4 strengthens the connection between the connecting nut 2 and the fixing nut 3, preventing the fixing nut 3 from sliding when the connecting nut 2 slides, thereby improving the practicality of the nut with a screw connection structure.

[0040] Specifically, the connecting nut 2 and the fixing nut 3 have the same internal structure, and both the connecting nut 2 and the fixing nut 3 are made of stainless steel.

[0041] In a specific embodiment of the utility model, the stainless steel setting of the connecting nut 2 and the fixing nut 3 makes the connecting nut 2 and the fixing nut 3 less likely to rust and affect subsequent use, thereby improving the durability of the nut with a screw connection structure.

[0042] Working principle: When in use, first screw the nut body 201 on the surface of the bolt body 1 through the internal thread ring 203 until the connecting hole 204 and the plug-in hole 7 are overlapped, and then insert the plug-in column 202 into the connecting hole 204 and the plug-in hole 7 to strengthen the connection between the nut body 201 and the plug-in hole 7, and then install the above steps to screw the fixing nut 3 to the surface of the bolt body 1, so that the fixing column 9 is inserted into the second fixing hole 10 to strengthen the connection between the connecting nut 2 and the fixing nut 3, and then stick the connecting sheet 4 on the surface of the connecting nut 2 and the fixing nut 3, and fix the connecting nut 2, the fixing nut 3 and the connecting sheet 4 through the fixing bolt 5 to prevent the connecting nut 2 from sliding after a long period of use and losing the fixing effect. The setting of the nylon ring 8 can also increase the friction when the bolt body 1 and the connecting nut 2 are connected to achieve a slight locking effect.
