Description

Technical Field

[0001] This utility model relates to the field of double-ended stud technology, and in particular to a double-ended stud that is easy to assemble and disassemble. Background Technology

[0002] A stud is a cylindrical fastener with threads at both ends. It is used to securely connect two or more parts together. They are available in coarse and fine thread versions to meet different connection requirements. The material is usually metal, such as carbon steel or stainless steel, to adapt to different environments and load requirements. Studs are widely used in power, chemical, oil refining, valve, railway, bridge, and steel structure construction fields. They are suitable for situations where the connected parts are too thick to use bolts or where frequent disassembly and assembly are not suitable for screw connections, such as the connection between cylinders and cylinder heads in automobiles, tractors, diesel engines, and other equipment.

[0003] Existing double-ended stud devices are not convenient for quick assembly and disassembly. Because there is no thread in the middle of the double-ended stud, the worker's palm will be very slippery when installing or removing the double-ended stud, making it difficult to assemble or disassemble, reducing work efficiency, and making it inconvenient to add lubricant. When the double-ended stud is connected to the connector, it is easy to encounter difficulties in rotation, making the connection between the double-ended stud and the connector unstable. Therefore, we propose a double-ended stud that is easy to assemble and disassemble to solve this problem. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-ended stud that is easy to assemble and disassemble includes a first stud, a connecting stud, and a second stud. The outer side of the connecting stud is movably fitted with an anti-slip sleeve. Connecting pieces are fixedly installed on both the left and right sides of the inner cavity of the anti-slip sleeve. An anti-slip pad is fixedly embedded on the outer side of the anti-slip sleeve. A connecting tube is fixedly installed on the right side of the top of the connecting stud. A sealing cap is threadedly connected to the top of the outer side of the connecting tube. A sealing gasket is fixedly installed on the top of the inner cavity of the sealing cap.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A double-ended stud that is easy to assemble and disassemble includes a first stud 1, a connecting stud 2, and a second stud 3. An anti-slip sleeve 4 is movably sleeved on the outer side of the connecting stud 2. Connecting pieces 8 are fixedly installed on both the left and right sides of the inner cavity of the anti-slip sleeve 4. An anti-slip pad 9 is fixedly embedded on the outer side of the anti-slip sleeve 4. A connecting tube 11 is fixedly installed on the right side of the top of the connecting stud 2. A sealing cap 10 is threadedly connected to the top of the outer side of the connecting tube 11. A sealing gasket 12 is fixedly installed on the top of the inner cavity of the sealing cap 10.

[0022] In this embodiment, the corresponding side of the connecting pieces 8 on both the left and right sides extends into the interior of the connecting post 2. The left and right sides of the connecting post 2 are provided with sliding grooves that are adapted to the connecting pieces 8. The outer side of the connecting piece 8 slides in contact with the inner cavity of the sliding groove. The inner cavity of the anti-slip sleeve 4 slides in contact with the outer side of the connecting post 2. The right side of the inner cavity of the connecting post 2 is fixedly provided with a first through groove 13. The bottom of the inner cavity of the connecting post 2 is fixedly provided with a second through groove 14. The outer side of the bottom of the connecting post 2 is fixedly provided with an oil seepage hole 15. The bottom of the connecting pipe 11 extends into the inner cavity of the connecting post 2 and is fixedly connected to the top of the first through groove 13. Through the cooperation of the connecting piece 8 and the sliding groove, the anti-slip sleeve 4 can be limited, which improves the stability of the anti-slip sleeve 4 in use.

[0023] In this embodiment, a nut 5 is screwed onto the top of the outer side of the first stud 1, a washer 6 is provided at the bottom of the nut 5, and an elastic washer 7 is provided at the bottom of the washer 6. Both the washer 6 and the elastic washer 7 are movably sleeved on the outer side of the first stud 1. The bottom of the first stud 1 is fixedly connected to the top of the connecting post 2, and the bottom of the connecting post 2 is fixedly connected to the top of the second stud 3. The bottom of the first through groove 13 is fixedly connected to the top of the second through groove 14, and the top of the oil seepage hole 15 is fixedly connected to the bottom of the second through groove 14. Through the cooperation of the washer 6 and the elastic washer 7, the connector can be protected, and the nut 5 can be prevented from scratching the connector.

[0024] In this embodiment, during use, the anti-slip sleeve 4 and anti-slip pad 9 allow the operator to easily grip the connecting post 2, enhancing the friction between the operator's hand and the connecting post 2. When the anti-slip sleeve 4 needs to be replaced, move the anti-slip sleeve 4 upwards, causing the connecting piece 8 to move upwards and away from the groove. Then, the new anti-slip sleeve 4 can be fitted in. When lubricating oil needs to be added, rotate the sealing cover 10 forwards to move it upwards and remove it. Then, pour the lubricating oil from the top of the connecting pipe 11. The lubricating oil flows out from the oil seepage hole 15 through the cooperation of the first through groove 13 and the second through groove 14, making it convenient for the operator to add lubricating oil between the double-ended stud and the connector.

[0025] The present invention provides a detailed description of a double-ended stud that is easy to assemble and disassemble. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
