Description

Technical Field

[0001] The utility model relates to the technical field of cup nuts, and particularly relates to a cup nut with a locking structure. Background Art

[0002] A nut is a screw cap, a part used for fastening by screwing together with a bolt or a screw rod. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc. Generally, a cup nut is used to fix a grinding wheel so that the grinding wheel can be stably used subsequently. However, the cup nut uses the mutual screwing between its internal thread and the screw rod to fasten the grinding wheel, but the nut itself does not have a good locking structure, resulting in the situation of reverse rotation due to vibration during use, and it is easy to cause the nut to fall off automatically. For this reason, we propose a cup nut with a locking structure. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a cup nut with a locking structure.

[0004] The technical solution adopted by the utility model to solve its technical problems is a cup nut with a locking structure, which includes a nut body. A ring groove for connection is opened on the top surface of the nut body, and a threaded column for locking is screwed and installed inside the ring groove. One end of the threaded column located inside the ring groove is integrally constructed with claw teeth for limiting, and there are multiple groups of claw teeth;

[0005] A groove is opened on the outer peripheral surface of the threaded column, and an inclined hole is opened on the bottom surface inside the groove. An inclined block for limiting is slidably installed inside the inclined hole, and a screw pin for pushing the displacement of the inclined block is screwed and installed inside the inclined hole.

[0006] By adopting the above technical solution, during the process of fastening the grinding wheel with the cup nut, after the nut body and the screw rod are used to fasten the grinding wheel, it is convenient to screw and connect the threaded column with the ring groove on the surface of the nut body. At the same time, multiple groups of claw teeth at one end of the threaded column are convenient to penetrate into the ring groove, and multiple groups of claw teeth are convenient to contract as they move and fit with the screw rod, facilitating the locking of the position of the nut body, thereby improving the stability of the nut body and enabling the cup nut to more stably fasten the grinding wheel;

[0007] After the threaded column and the nut body are screwed and connected, it is convenient to screw the screw pin into the inclined hole and push the inclined block in the inclined hole, so that one end of the inclined block can extend into the threaded column and abut against the screw rod, facilitating the auxiliary locking of the position of the threaded column and further improving the stability of the cup nut after use.

[0008] Specifically, an inclined groove communicating with the annular groove is formed on the inner side of the nut body.

[0009] By adopting the above technical solution, the inclined groove facilitates the mutual abutment with multiple sets of claw teeth and enables the claw teeth to slide along the inclined groove, so that the multiple sets of claw teeth can contract and approach each other, which is convenient for locking.

[0010] Specifically, a sliding groove for limiting is formed on the inner peripheral surface of the inclined hole, and a sliding block that is integrally formed on the outer peripheral surface of the inclined block and is fitted and connected with the sliding groove.

[0011] By adopting the above technical solution, the sliding grooves are mutually fitted and slide, and the end of the sliding groove located inside the inclined hole is not communicated with the screw hole on the inner circumference of the threaded column, so that the inclined block slides in the inclined hole and does not completely enter the screw hole on the inner circumference of the threaded column, enabling the inclined block to be used more stably.

[0012] Specifically, a rubber block for protection is bonded to one end of the screw pin close to the inclined block.

[0013] By adopting the above technical solution, the rubber block is convenient for reducing the abrasion caused by friction between the screw pin and the inclined block.

[0014] Specifically, two groups of grooved slots for rotation are formed on the outer peripheral surface of the threaded column.

[0015] By adopting the above technical solution, the two groups of grooved slots on the outer periphery of the threaded column are convenient for cooperating with the handle, enabling the threaded column to be disassembled and assembled more conveniently.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. Through the design of the annular groove, the threaded column and the claw teeth in the technical solution of the present application, during the process of tightening the grinding wheel with the cup-shaped nut, after the nut body and the screw rod are tightened with each other to fasten the grinding wheel, it is convenient to screw the threaded column and the annular groove on the surface of the nut body together. At the same time, multiple groups of claw teeth at one end of the threaded column are convenient to penetrate into the inner side of the annular groove. At the same time, the multiple groups of claw teeth are convenient to contract as they move and fit with the screw rod, which is convenient for locking the position of the nut body, thereby improving the stability of the nut body and enabling the cup-shaped nut to tighten the grinding wheel more stably.

[0018] 2. Through the design of the groove, the inclined hole, the screw pin and the inclined block in the technical solution of the present application, after the threaded column and the nut body are screwed together, it is convenient to screw the screw pin into the inclined hole and push the inclined block in the inclined hole, so that one end of the inclined block can extend into the threaded column and abut against the screw rod, which is convenient for assisting in locking the position of the threaded column and further improving the stability of the cup-shaped nut after use.

An inclined block 8 for limiting is slidably installed inside the inclined hole 7, and a screw pin 9 for pushing the inclined block 8 to displace is screwed and installed inside the inclined hole 7.

[0026] When in use, during the process of tightening the grinding wheel with the cup-shaped nut, after the nut body 1 and the screw rod are tightened against the grinding wheel, it is convenient to screw the threaded post 3 and the annular groove 2 on the surface of the nut body 1 together. At the same time, multiple groups of claw teeth 5 at one end of the threaded post 3 are convenient to penetrate into the inside of the annular groove 2, and multiple groups of claw teeth 5 are convenient to contract with the movement and fit with the screw rod, facilitating the locking of the position of the nut body 1, thereby improving the stability of the nut body 1, so that the cup-shaped nut can tighten the grinding wheel more stably;

[0027] When the threaded post 3 and the nut body 1 are screwed together, it is convenient to screw the screw pin 9 into the inclined hole 7 and push the inclined block 8 in the inclined hole 7, so that one end of the inclined block 8 can extend into the threaded post 3 and abut against the screw rod, facilitating the auxiliary locking of the position of the threaded post 3 and further improving the stability of the cup-shaped nut after use.

[0028] As Figure 2 shown, an inclined groove 4 communicating with the annular groove 2 is provided inside the nut body 1.

[0029] During use, the inclined groove 4 facilitates mutual abutment with multiple sets of claw teeth 5 and enables the claw teeth 5 to slide along the inclined groove 4, so that the multiple sets of claw teeth 5 can contract and approach each other, facilitating locking.

[0030] As Figure 3 shown, a sliding groove 11 for limiting is provided on the inner peripheral surface of the inclined hole 7, and a sliding block 12 that fits and connects with the sliding groove 11 is integrally formed on the outer peripheral surface of the inclined block 8.

[0031] During use, the sliding groove 11 and the sliding groove 11 fit and slide with each other, and one end of the sliding groove 11 located inside the inclined hole 7 is not communicated with the screw hole inside the inner circumference of the threaded column 3, so that the inclined block 8 slides in the inclined hole 7 and does not completely enter the screw hole inside the inner circumference of the threaded column 3, enabling the inclined block 8 to be used more stably.
