[0002] For the existing cap nuts that are convenient to replace, the cap part of the cap nut is designed as a detachable structure. When the cap is damaged, only the cap needs to be removed for replacement, avoiding the situation of removing the nut for replacement. However, no anti-vibration components are provided, so it cannot be used on equipment that will generate vibration. For example, a cap nut that is convenient to replace disclosed in a Chinese patent, with the application number CN201720026017.3, although it can prevent water and dust from entering the bolt body, and through the setting of the fastening ring, it is beneficial to fix the nut body after it is broken to prevent accidents, but it does not solve the problem that the nut is prone to loosen when used on equipment that will generate vibration, and at the same time, it does not solve the method of removing the replacement structure when it is stuck, so its use has limitations. Content of the Utility Model

At the same time, it also has a certain elasticity to prevent the replacement part from loosening due to vibration of the device during operation.

[0009] A cap nut that is easy to replace according to the present utility model. One end of the threaded rod away from the first nut extends into the second nut during operation, and the external thread is threadedly connected to the internal thread two during operation. Through the above components, the nut body and the replacement part can be fixed under the action of the external thread on the threaded rod and the internal thread two on the second nut.

[0010] A cap nut that is easy to replace according to the present utility model. A communication groove is provided at one end of the cap close to the second nut, and the communication groove is located below the through hole. Through the above components, the bolt connected to the cap nut can extend into the communication groove for fixing and protection, and when the replacement part is not easily removed, a hard object can be inserted into the through hole and rotated to remove the replacement part.

[0011] A cap nut that is easy to replace according to the present utility model. A bolt chamfer is provided at one end of the threaded rod away from the first nut, and the direction of the internal thread one is opposite to that of the external thread. Through the above components, the bolt chamfer makes the threaded rod smoother during installation, reducing the risk of jamming, and by making the spiral directions of the internal thread one and the external thread opposite, the situation where the replacement part and the cap nut affect each other when removed separately is prevented.

[0019] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0020] Refer to Figures 1-4 , an embodiment of a cap nut that is easy to replace according to the present utility model includes: a nut body 2, which is fixedly connected by threaded connection with a matching bolt. A rubber washer 1 is fixedly connected to the lower surface of the nut body 2. One end of the rubber washer 1 close to the nut one 5 extends into the interior of the nut one 5. To increase the frictional resistance between the nut body 2 and the connecting device and prevent the nut one 5 from loosening due to vibration during the operation of the connecting device, a connecting ring 3 is fixedly connected to the upper surface of the nut body 2. The connecting ring 3 is located between the nut one 5 and the nut two 10, separating the nut body 2 from the replacement part 4 to prevent the replacement part 4 from being unable to be removed for replacement due to tight fixation. At the same time, it also has a certain elasticity to prevent the replacement part 4 from loosening due to vibration during the operation of the device. At the same time, it also prevents water and dust from entering the bolt through the gap to corrode the bolt. The end of the nut body 2 far from the rubber washer one 1 is threadedly connected with a replacement part 4, sealing the threaded end of the bolt to prevent the bolt from protruding from the nut and causing harm to people or objects, and can be replaced, improving the practicability;

[0021] The nut body 2 includes a first nut 5. The lower surface of the first nut 5 is fixedly connected to the rubber washer 1, and the upper surface of the first nut 5 is fixedly connected to the connecting ring 3, which is connected to a matching bolt. A threaded rod 7 is fixedly connected to the upper surface of the first nut 5. One end of the threaded rod 7 away from the first nut 5 extends into the interior of the second nut 10 during operation and is connected to the replacement part 4 to facilitate the disassembly and replacement of the replacement part 4. Internal threads 6 are provided on the inner sides of both the first nut 5 and the threaded rod 7, and are threadedly connected to a matching bolt to fix the nut body 2 and the bolt together. An external thread 8 is provided on the side surface of the threaded rod 7, and the external thread 8 is threadedly connected to the internal thread 11 during operation and is adapted to the internal thread 11 on the second nut 10, facilitating the disassembly and fixation of the replacement part 4;

[0022] The replacement part 4 includes a second nut 10. The lower surface of the second nut 10 is in contact with the connecting ring 3 during operation and is fixed to the threaded rod 7 through the internal thread 11. A cap 13 is fixedly connected to the upper surface of the second nut 10 to seal the end of the bolt and prevent the bolt from protruding from the nut and harming the human body. Internal threads 11 are provided on the inner side of the second nut 10, and are adapted to the external thread 8 to fix the second nut 10 and the threaded rod 7 together. Through holes 14 are provided on the side surface of the cap 13. When the replacement part 4 is stuck to the nut body 2, other objects can be inserted into the through holes 14 and rotated to remove the replacement part 4.

[0023] A communication groove 12 is provided at one end of the cap 13 close to the second nut 10. The communication groove 12 is located below the through hole 14 and is used to place the end of the bolt to prevent the bolt from protruding from the nut and causing harm to people or objects. A bolt chamfer 9 is provided at one end of the threaded rod 7 away from the first nut 5, making the installation process of the threaded rod 7 smoother, reducing the risk of jamming, and thus improving the installation efficiency. The directions of the internal thread 6 and the external thread 8 are opposite. By making the directions of the internal thread 6 and the external thread 8 opposite, the situation where the replacement part 4 and the cap nut are removed separately and affect each other is prevented.

[0024] Working principle: Insert the end of the fixing bolt into the nut body 2 and thread-connect the two by rotation. The rubber washer 1 is located between the two to improve the fixing effect by using friction. Then insert the second nut 10 in the replacement part 4 towards the threaded rod 7 and rotate until the second nut 10 contacts the connecting ring 3 to fix the nut body 2 and the replacement part 4 together. When the replacement part 4 needs to be replaced, it can be removed by simply rotating it in the reverse direction. If the replacement part 4 is stuck, a strong object can be inserted into the through hole 14 to drive the cap 13 to rotate to remove the replacement part 4.

[0025] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
