DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, refer to Figure 1-5 As shown: a cylinder-pushed compression sealing cap comprises a sealing cap body 1, a connecting rod 5 is fixedly connected to one side of the inner wall of the sealing cap body 1, a clamping mechanism is arranged on one side of the connecting rod 5, the clamping mechanism comprises a sealing gasket 2, an elastic telescopic rod 6 and a built-in block 7, one side of the sealing gasket 2 is fixedly connected to the sealing cap body 1, both ends of the elastic telescopic rod 6 are hinged with hinges 9, one side of one hinge 9 is fixedly connected to the sealing gasket 2, one side of the sealing gasket 2 is fixedly connected to a fixed block 16, one end of the fixed block 16 is fixedly connected to the connecting rod 5, a spring 8 is fixedly connected to the outer ring surface of the fixed block 16, one end of the spring 8 is fixedly connected to the built-in block 7, one side of the built-in block 7 is overlapped with the inner wall of the sealing cap body 1, and one side of the other hinge 9 is fixedly connected to a reinforcement ring 10, an extension shaft 18 is inserted through the inside of the reinforcement ring 10, one end of the extension shaft 18 is fixedly connected to the elastic telescopic rod 6, one side of the reinforcement ring 10 is fixedly connected to a connecting strip 17, and one side of the connecting strip 17 is fixedly connected to the sealing gasket 2.

[0024] The connecting rod 5 can be used to connect the fixing block 16 and the inner wall of the sealing cap main body 1, so as to support and reinforce the fixing block 16. The outer ring surface of the fixing block 16 is connected to the built-in block 7 through the spring 8. The compression strength of the built-in block 7 on the inner wall of the sealing cap main body 1 can be controlled by the contraction of the spring 8. When the inner wall of the sealing cap main body 1 is pressurized, the outer ring surface of the sealing cap main body 1 can be slightly deformed, so that the diameter of this part is slightly larger than the diameter on the left side. Therefore, the fitting effect between the outer ring surface of the sealing cap main body 1 and the inner wall of the installation position can be improved, thereby reducing the looseness of the sealing cap main body 1 after installation. The hinge 9 can be used to connect the two ends of the elastic telescopic rod 6. The elastic telescopic rod 6 can be used to support one side of the sealing pad 2, further reducing the looseness of the sealing cap main body 1 and ensuring the sealing effect of the sealing sleeve when in use.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, one end of the extension shaft 18 is fixedly connected to the limiting sleeve 4, the inner ring surface of the limiting sleeve 4 is fixedly connected to the limiting tube 11, the cylinder connecting shaft 3 is inserted into the limiting tube 11, the outer ring surface of the limiting sleeve 4 is fixedly connected to the limiting block 15, the limiting block 15 is connected to the limiting bolt 14 through a thread, the end of the limiting bolt 14 is inserted with an adjusting rod 13, the outside of the adjusting rod 13 is inserted with an eccentric wheel 12, one side of the eccentric wheel 12 passes through the side wall of the limiting sleeve 4, the outer ring surface of the eccentric wheel 12 is overlapped with the cylinder connecting shaft 3, the outer ring surface of the adjusting rod 13 is provided with a positioning hole, and the adjusting rod 13 and the limiting sleeve 4 are rotatably connected.

[0026] The limiting sleeve 4 can be used to increase the wrapping area of ​​the cylinder connecting shaft 3. The limiting tube 11 is sleeved on the outside of the cylinder connecting shaft 3. The insertion depth of the cylinder connecting shaft 3 can be limited by the extension shaft 18. After the cylinder connecting shaft 3 is inserted, the eccentric wheel 12 can be used to limit the cylinder connecting shaft 3 to reduce the loosening of the cylinder connecting shaft 3. The limiting bolt 14 can fix the position of the adjusting rod 13, thereby avoiding the loosening of the cylinder connecting shaft 3 caused by the loosening of the eccentric wheel 12, thereby ensuring the connection effect between the cylinder connecting shaft 3 and the limiting sleeve 4 and the extension shaft 18, so that the cylinder can stably drive the sealing cap to move and install. After the sealing cap is installed, the eccentric wheel 12 is rotated in the opposite direction to quickly separate the cylinder connecting shaft 3 from the limiting sleeve 4, and the overall operation is more convenient.

[0027] The method of use and working principle of the device are as follows: first, before the entire sealing cap is used, the right end of the sealing cap is connected to the cylinder connecting shaft 3, one end of the cylinder connecting shaft 3 is inserted into the limiting sleeve 4 and the extension shaft 18, the limiting tube 11 is sleeved on the outside of the cylinder connecting shaft 3, and then the adjusting rod 13 is rotated on the upper and lower sides of the limiting sleeve 4, so that the adjusting rod 13 drives the eccentric wheel 12 to rotate, so that the outer ring surface of the eccentric wheel 12 is against the side wall of the cylinder connecting shaft 3, and then the limiting bolt 14 is installed between the limiting block 15 and the adjusting rod 13 to fix the position of the eccentric wheel 12, and the eccentric wheel 12 arranged symmetrically above and below is used to clamp and fix the cylinder connecting shaft 3, and the cylinder is used to The cylinder body at one end of the connecting shaft 3 can drive the cylinder connecting shaft 3 and the sealing cap body 1 to move, so that the sealing cap body 1 made of rubber material is inserted into the installation area. At this time, the spring 8 applies a force to the built-in block 7, and the built-in block 7 applies a force from the axis to the outside to the sealing cap body 1, so that the outer ring surface of the sealing cap body 1 is tightly fitted with the installation position. At this time, one side of the sealing gasket 2 is engaged with the one side of the installation position, and the end of the elastic telescopic rod 6 applies a force to the sealing gasket 2, so that the sealing gasket 2 is more closely fitted with the installation position, thereby improving the stability of the sealing cap installation. At this time, the two limit bolts 14 can be removed to separate the cylinder connecting shaft 3 from the limit sleeve 4.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
