[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] See also Figure 1-Figure 5 The utility model provides a technical solution: a stainless steel combination screw, including a stainless steel screw 1, a threaded opening 2 is opened on the top of the stainless steel screw 1, a gasket 3 is sleeved on the stainless steel screw 1, a limiting component 4 is provided on the side of the stainless steel screw 1, the stainless steel screw 1 is connected to the gasket 3 through the limiting component 4, a protective component 5 is provided at the front end of the stainless steel screw 1, and the stainless steel screw 1 protects the threaded opening 2 through the protective component 5.

[0024] The limiting component 4 includes a movable warehouse 41 arranged on the left outer wall of the stainless steel screw 1, and two groups of sliding grooves 42 are opened on the inner wall of the movable warehouse 41. Slide blocks 43 are slid in the sliding grooves 42, and brake rings 44 are arranged in the middle of the slide blocks 43. A plug rod 45 is arranged in the middle of the brake ring 44. A spring 46 is wound on the surface of the plug rod 45 above the brake ring 44, and a slot 47 is opened on the surface of the gasket 3 corresponding to the bottom end surface of the plug rod 45. A pull handle 48 is arranged on the plug rod 45. The protective component 5 includes a fixed seat 51 arranged on the front end surface of the stainless steel screw 1, a rotating rod 52 is rotatably arranged in the fixed seat 51, a torsion spring 53 is wound on the surface of the rotating rod 52, a cover plate 54 is arranged on the top of the rotating rod 52, a fixed plate 55 is arranged on the front end surface of the fixed seat 51, a threaded rod 56 is rotatably arranged on the inner thread of the fixed plate 55, and a threaded groove 57 is opened on the surface of the rotating rod 52 corresponding to the rear end surface of the threaded rod 56, and the threaded groove 57 is threadedly connected to the threaded rod 56.

[0025] By setting a limit component 4 between the stainless steel screw 1 and the gasket 3, the insertion rod 45 in the limit component 4 is inserted into the slot 47 under the push of the restoring force of the spring 46, so as to achieve the purpose of rotation limiting the stainless steel screw 1, so that the limit component 4 can limit the loosening degree of the stainless steel screw 1 when subjected to external force or vibration, maintain the stability of the connection, and thus improve the safety of the equipment or structure. By setting a protective component 5 outside the threaded opening 2, the rotating rod 52 in the protective component 5 is driven by the restoring force of the torsion spring 53 to reset and rotate in the fixing seat 51, and simultaneously drives the cover plate 54 to cover the threaded opening 2, and then the threaded rod 56 is rotated in the inner thread of the fixing plate 55 and rotated into the thread groove 57, so that the cover plate 54 protects the threaded opening 2, prevents dust or debris from accumulating inside the threaded opening 2, keeps it clean and tidy, and thus extends its service life and performance.

[0026] like Figure 4 As shown, the pull handle 48 is designed in a C shape, and the pull handle 48 and the insertion rod 45 are rotatably connected. Through this design, it is convenient for the staff to use the pull handle 48 to pull the insertion rod 45, so that the insertion rod 45 drives the slider 43 to slide in the slide groove 42 through the brake ring 44, and the insertion rod 45 slides out of the slot 47, thereby achieving the purpose of releasing the rotation limit of the stainless steel screw 1. At the same time, when the pull handle 48 is not needed, the pull handle 48 is rotated on the insertion rod 45 and turned away from the top of the insertion rod 45 to fit the surface of the movable bin 41, thereby reducing the external space occupied by the pull handle 48.

[0027] like Figure 4 As shown, the slider 43 is designed to be semicircular, and the slide groove 42 is opened as a through hole identical to the slider 43. The slider 43 and the slide groove 42 are both adapted to each other. Through this design, the friction damage of the slider 43 in the slide groove 42 can be reduced, while the stability of the brake ring 44 moving up and down in the movable chamber 41 is improved, thereby ensuring the connection stability between the insertion rod 45 and the slot 47.

[0028] like Figure 5 As shown, a rubber ring is provided on the bottom surface of the cover plate 54, and the cover plate 54 is designed to be transparent. Through this design, the sealing performance between the cover plate 54 and the surface of the stainless steel screw 1 can be increased to prevent the gap between the cover plate 54 and the stainless steel screw 1 from being too large, and foreign matter from entering the threaded opening 2 through the gap to contaminate the threaded opening 2. At the same time, it is also convenient for the staff to observe the hygiene inside the threaded opening 2 from the outside of the cover plate 54.

[0029] like Figure 5As shown, the torsion spring 53 is wound and arranged at the middle section of the rotating rod 52, and both ends of the torsion spring 53 are fixed on the inner wall of the fixing seat 51. Through this design, the restoring force of the torsion spring 53 can be evenly transmitted to the two ends of the rotating rod 52, so that the rotating rod 52 is more stable when rotating in the fixing seat 51.

[0030] The method of use and working principle of the device are as follows: when in use, first pull the handle 48 in the direction away from the threaded opening 2, so that the handle 48 drives the slider 43 to slide in the slide groove 42 through the insertion rod 45 and the brake ring 44, and the brake ring 44 squeezes the spring 46, causing the spring 46 to deform, and then put the gasket 3 on the stainless steel screw 1, so that the stainless steel screw 1 is screwed on the object and fits with the gasket 3 until the slot 47 on the gasket 3 is aligned with the insertion rod 45, and then release the handle 48. At this time, the restoring force generated by the squeezing of the spring 46 pushes the brake ring 44, so that the brake ring 44 drives the slider 43 to return to its original position and slide in the slide groove 42, and the insertion rod 45 is inserted into the slot 47, so as to achieve the purpose of limiting the rotation of the stainless steel screw 1.

[0031] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
