DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] See also Figures 1 - 4 The utility model provides a technical solution: a sealing spring nut assembly, including a nut block 1, a sealing spring 2, an internal thread 3, a replacement assembly 4, an internal groove 5, a rotation groove 6 and a positioning groove 7, the sealing spring 2 includes a spring ring 21, a welding ring 22 and a mounting ring 23, wherein the welding ring 22 is located on the inner side of the mounting ring 23, and the top of the spring ring 21 is welded to the position of the welding ring 22, an internal thread 3 is opened at the center position of the nut block 1, and an internal groove 5 is also arranged on the outer periphery of the internal thread 3, and the replacement assembly 4 is arranged On the nut block 1, the replacement component 4 is connected to the rotating groove 6 in the nut block 1, and a plurality of positioning grooves 7 are distributed on the rotating groove 6. The replacement component 4 includes a concave-convex surface 41, a rotating ring outer ring 42, a rotating ring inner ring 43, a telescopic sleeve 44, and a connecting pull rope 45. The concave-convex surface 41 is assembled on the surface of the rotating ring outer ring 42, and a connecting pull rope 45 is also installed on the inner side of the rotating ring outer ring 42. The connecting pull rope 45 is fixed together with the telescopic sleeve 44 on the rotating ring inner ring 43, and a plurality of telescopic sleeves 44 are installed on the rotating ring inner ring 43.

[0020] As the first embodiment of the utility model: the size of the installation ring 23 matches the size of the inner groove 5 on the nut block 1. The design directly sleeves the sealing spring 2 in the inner groove 5 on the nut block 1 through the installation ring 23. The structure is simple and easy to operate. The size width of the positioning groove 7 matches the size of the telescopic sleeve 44 on the inner ring 43 of the rotating ring. The design is matched by setting a plurality of positioning grooves 7 and telescopic sleeves 44, which helps to use the telescopic sleeve 44 to limit the positioning of the installation ring 23, and then install and fix the sealing spring 2. The concave and convex surface 41 is added with a plastic material with strong friction. The design helps to increase the user's control over the outer ring 4 of the rotating ring. 2 is a fulcrum, which is convenient for users to rotate the rotating ring on the nut block 1. The telescopic sleeve 44 is assembled from a multi-section sleeve, and the size of the telescopic sleeve 44 is consistent with the size of the positioning groove 7 distributed on the rotating groove 6. The design adopts a telescopic multi-section sleeve to assemble the telescopic sleeve 44, which is convenient for the telescopic sleeve 44 to be extended and retracted, thereby improving the efficiency of the installation ring 23. The connecting pull rope 45 is connected to the top position of the telescopic sleeve 44 in a binding manner. The design uses the connecting pull rope 45 as a device for controlling the extension and retraction of the telescopic sleeve 44, together with the rotating ring, and the telescopic sleeve 44 is kept extended or extended by tightening and loosening the connecting pull rope 45. The structure is reasonable and simple.

[0021] As the second embodiment of the present utility model: When replacing the sealing spring 2 on the nut block 1, first rotate the rotating ring on the nut block 1. The outer ring 42 of the rotating ring rotates clockwise by the user's screwing on the concave-convex surface 41. Since the connecting pull rope 45 installed on the outer ring 42 of the rotating ring is connected to the telescopic sleeve 44 on the inner ring 43 of the rotating ring, when the outer ring 42 of the rotating ring rotates clockwise, the connecting pull rope 45 will pull the top of the telescopic sleeve 44, causing the telescopic sleeve 44 to contract along the connecting pull rope 45. In this way, when the telescopic sleeve 44 contracts from the clamping groove 7 in the rotating groove 6, the mounting ring 23 loses the restriction and fixation of the telescopic sleeve 44. Therefore, the sealing spring 2 welded to the welding ring 22 of the mounting ring 23 will be removed from the inner connection groove 5 together with the mounting ring 23. Since sealing springs 2 with different specification coefficients are welded to mounting rings 23 of the same size, when replacing sealing springs 2 with different specification coefficients, similarly, directly put the mounting ring 23 welded with a sealing spring 2 of another specification coefficient into the inner connection groove 5, and then rotate the outer ring 42 of the rotating ring counterclockwise so that the connecting pull rope 45 no longer tightens the top of the telescopic sleeve 44. In this way, the telescopic sleeve 44 will extend again from the clamping groove 7 and firmly restrict and clamp the mounting ring 23, meeting the requirement of quickly installing and disassembling the sealing spring.
