Therefore, a new technical scheme needs to be designed to solve it. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the defects of prior art, adapting to the actual needs, providing a kind of quartz tube cap for sealing quartz tube to solve the technical problems, such as the firmness when the quartz tube cap for sealing quartz tube is installed on the quartz tube is poor and the disassembly is not convenient, and the quartz tube cap and the quartz tube are prone to loosening.

[0005] In order to realize the purpose of the utility model, the technical scheme adopted by the utility model is as follows: a quartz tube cap for sealing quartz tube is designed, which comprises a cap body, three sealing rings are fixedly connected to the outside of the cap body, three through grooves are further formed around the cap body, a limiting sleeve is fixedly connected to the bottom of the cap body, a pressing column is connected to the inside of the limiting sleeve through a spring piece, a connecting arm is connected to the other end of the pressing column through a mounting plate, a rubber abutting block is installed at the other end of the connecting arm, a square pressing block is fixedly connected to the other end of the mounting plate, a cover plate is installed at the top end of the cap body, a square groove is formed in the middle of the cover plate, and a limiting plate is connected to the square groove through a limiting frame.

[0006] Preferably, the spring member is movably connected inside the limiting sleeve, one end of the extrusion column is slidably connected to the inner wall of the limiting sleeve and abuts against one end of the spring member, and the other end of the extrusion column is fixedly connected to one end of the mounting plate.

[0007] Preferably, one end of the connecting arm is rotatably connected to the side surface of the mounting plate, and the other end of the connecting arm is rotatably connected to one end of the rubber abutting block.

[0008] Preferably, one end of the rubber abutting block is movably connected to the inner wall of the through groove and extends to the outside of the cap body.

[0009] Preferably, the square pressing block is in a size matching that of the square groove and is slidably connected to the inner wall thereof.

[0010] Preferably, the limiting frame is fixedly connected to the surface of the cover plate, one end of the limiting plate is slidably connected to the inside of the limiting frame, and the bottom of the limiting plate is in contact with the surface of the cover plate.

[0011] Compared with the prior art, the quartz tube cap fixing device has the following beneficial effects:

[0012] When the quartz tube cap is installed and fixed, first, the end of the cap body with the sealing ring is inserted into the inside of the quartz tube, and then the square pressing block is moved downward in the square groove. At this time, the mounting plate drives the extrusion column to move in the inside of the limiting sleeve and extrude the spring member. In this process, the connecting arm rotates on the mounting plate and the rubber abutting block, so that the rubber abutting block is moved from the inside of the cap body to the outside through the through groove, thereby abutting against the inside of the quartz tube, so that the quartz tube cap is installed and fixed, the firmness when the quartz tube cap is installed on the quartz tube and the convenience when the quartz tube cap is disassembled are improved, and the phenomenon that the quartz tube cap and the quartz tube are loose is avoided.

[0013] When the square pressing block is retracted into the square groove, the limiting plate is removed from the inside of the limiting frame, so that part of the limiting plate is shielded outside the square groove, thereby limiting the position of the square pressing block. When the limiting plate is removed from the position of the square groove, the spring member generates a rebound force on the extrusion column, thereby driving the square pressing block to reset. In this process, the connecting arm also drives the rubber abutting block to reset, thereby improving the convenience of the quartz tube cap in use. BRIEF DESCRIPTION OF DRAWINGS

[0021] The utility model is further explained in connection with the drawings and examples:

[0022] Example 1: a quartz tube cap for sealing quartz tube, refer to Figures 1 to 5The device includes a cap body 1, with three sealing rings 11 fixedly connected to the outside of the cap body 1. Three through slots 12 are also formed around the cap body 1. A limiting sleeve 13 is fixedly connected to the bottom inside the cap body 1. A pressing column 15 is connected to the inside of the limiting sleeve 13 via a spring member 14. The other end of the pressing column 15 is connected to a connecting arm 17 via a mounting plate 16. A rubber abutment block 18 is installed at the other end of the connecting arm 17. A square pressing block 19 is fixedly connected to the other end of the mounting plate 16. The spring member 14 is movably connected inside the limiting sleeve 13. One end of the pressing column 15 is slidably connected to the inner wall of the limiting sleeve 13 and abuts against one end of the spring member 14. The other end of the pressing column 15 is fixedly connected to one end of the mounting plate 16. One end of the connecting arm 17 is rotatably connected to the side of the mounting plate 16, and the other end of the connecting arm 17 is rotatably connected to the... One end of the rubber abutment block 18 is movably connected to the inner wall of the through groove 12 and extends to the outside of the cap body 1. When the quartz tube cap is installed and fixed, the end of the cap body 1 with the sealing ring 11 is first inserted into the inside of the quartz tube, and then the square pressing block 19 is moved downward inside the square groove 21. At this time, the mounting plate 16 will drive the extrusion column 15 to move inside the limiting sleeve 13 and extrude the spring 14. During this process, the connecting arm 17 will rotate on the mounting plate 16 and the rubber abutment block 18, thereby moving the rubber abutment block 18 from the inside of the cap body 1 through the through groove 12 to the outside, so that the rubber abutment block 18 abuts against the inside of the quartz tube, thus realizing the installation and fixing of the quartz tube cap, improving the firmness of the quartz tube cap when installed on the quartz tube and the convenience of disassembly and assembly, and avoiding the phenomenon of loosening between the quartz tube cap and the quartz tube.

[0023] A cover plate 20 is installed at the top of the cap body 1. A square groove 21 is formed in the middle of the cover plate 20. One side of the square groove 21 is connected to a limiting plate 23 via a limiting frame 22. The size of the square pressing block 19 matches the size of the square groove 21 and is slidably connected to its inner wall. The limiting frame 22 is fixedly connected to the surface of the cover plate 20. One end of the limiting plate 23 is slidably connected to the inside of the limiting frame 22. The bottom of the limiting plate 23 is in contact with the surface of the cover plate 20. When the square pressing block 19 is pressed... When block 19 retracts into the square groove 21, the limiting plate 23 is moved out from the inside of the limiting frame 22, so that part of the limiting plate 23 covers the outside of the square groove 21, thereby restricting the position of the square pressing block 19. When the limiting plate 23 moves away from the position of the square groove 21, the spring 14 will generate a rebound force on the pressing column 15, thereby driving the square pressing block 19 to reset. During this process, the connecting arm 17 will also drive the rubber abutment block 18 to reset, improving the convenience of using the quartz cap.
