Description

Technical Field

[0001] The utility model relates to the field of screw caps, and particularly relates to a screw cap anti-dropping device. Background Art

[0002] For existing products with screw caps, when installing or connecting wires at high altitude, it is necessary to open the screw cap, which is prone to falling from a height, resulting in safety accidents or bringing great inconvenience. Also, when installing in a narrow area, since there is no place to place the removed screw cap, it is difficult to install. This brings many uncontrollable factors to the installation and maintenance of this type of product, and affects system safety. In the domestic market, this type of technical problem has not been satisfactorily solved.

[0003] The patent application with publication number CN208453513U discloses an improved screw cap, which includes an outer cap and a screw inner cap with threads around the periphery below the outer shell. A sealing gasket is arranged at the connection between the outer cap and the inner cap. The outer cap includes a cap body and a convex block protruding outward in the circumferential direction on the outer peripheral edge above the cap body. A groove is arranged between adjacent convex blocks. A triangular cross-section protrusion is arranged on the lowermost surface of the inner cap, and the protrusion is hollow, and the top of the protrusion is a plane parallel to the horizontal plane.

[0004] In this existing technical structure, when opening the screw cap for operation, the screw cap is prone to falling, resulting in safety accidents or bringing great inconvenience.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a screw cap anti-dropping device. A special mechanism is arranged between the screw body and the screw cap to prevent it from falling when opening the cap at high altitude. Screws are respectively connected between the screw body and the screw cap to ensure that when opening the screw cap, the screw cap is finally connected to the screw body through this mechanism, and the high-altitude dropping of the screw cap will not occur.

[0007] The technical solution adopted by the utility model is:

[0008] A screw cap anti-dropping device includes a connecting device arranged between a screw body and a screw cap. The connecting device includes high-strength shoulder screws, steel rings, metal braided belts, and metal fixing screws. Both ends of the metal braided belt are respectively connected and fixed to the screw cap and the screw body through high-strength shoulder screws and metal fixing screws.

[0009] By adopting the above structure, a connecting device is arranged between the screw body and the screw cap to respectively connect the screw body and the screw cap, ensuring that when opening the screw cap, the screw cap is finally connected to the screw body through the connecting device, and the high-altitude dropping of the screw cap will not occur.

[0010] Preferably, steel rings are connected to both ends of the metal braided belt by crimping. The metal braided belt is connected to the threaded cover and the threaded body through the steel rings and high-strength shoulder screws and metal fixing screws respectively.

[0011] By adopting the above structure, steel rings are provided at both ends of the metal braided belt, and the firmness of the device after connection is higher.

[0012] Preferably, the connection part between the high-strength shoulder screw and the steel ring is at the center of the thread rotation of the threaded cover.

[0013] Preferably, there is a gap between the high-strength shoulder screw and the steel ring.

[0014] By adopting the above structure, when the threaded cover is unscrewed or tightened, it can be ensured that the metal braided belt will not be entangled due to rotation, avoiding damage to the metal braided belt caused by winding.

[0015] Preferably, the steel ring at the end of the metal braided belt is fixedly connected to the threaded body through metal fixing screws, spring washers and plain washers.

[0016] By adopting the above structure, the connection between the metal braided belt and the threaded body is firm.

[0017] Preferably, an O-ring is provided in the thread engagement surface after the threaded body and the threaded cover are helically fixed.

[0018] By adopting the above structure, the sealing performance between the threaded body and the threaded cover is better.

[0019] Preferably, a lock block is provided on the threaded body at the edge of the threaded cover. After the threaded body and the threaded cover are helically fixed, the lock block covers the edge of the threaded cover and is fixed by a fastening bolt.

[0020] By adopting the above structure, the connection between the threaded body and the threaded cover is reinforced by the lock block after connection, and the structural connection is more stable.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0030] As Figures 1-4 shown, a threaded cap anti-detachment device includes a connecting device provided between a threaded body 1 and a threaded cap 2. The connecting device includes a high-strength shoulder screw 4, a steel ring 5, a metal braid 6, and a metal fixing screw 7. Both ends of the metal braid 6 are respectively connected and fixed to the threaded cap 2 and the threaded body 1 through the high-strength shoulder screw 4 and the metal fixing screw 7. A connecting device is provided between the threaded body 1 and the threaded cap 2 and is respectively connected between the threaded body 1 and the threaded cap 2 to ensure that when the threaded cap 2 is opened, the threaded cap 2 is finally connected to the threaded body 1 through the connecting device, and the high-altitude detachment of the threaded cap 2 will not occur.

[0031] Both ends of the metal braid 6 are connected with steel rings 5 by a crimping method. The metal braid 6 is respectively connected to the threaded cap 2 and the threaded body 1 through the steel rings 5 and the high-strength shoulder screw 4 and the metal fixing screw 7. The connection part between the high-strength shoulder screw 4 and the steel ring 5 is at the center of the thread rotation of the threaded cap 2. There is a gap between the high-strength shoulder screw 4 and the steel ring 5. The steel ring 5 at the end of the metal braid 6 is fixedly connected to the threaded body 1 through the metal fixing screw 7, a spring washer, and a plain washer. Steel rings 5 are provided at both ends of the metal braid 6, which makes the device more firm after connection. There is a gap between the high-strength shoulder screw 4 and the steel ring 5, which can ensure that the metal braid 6 will not be entangled due to rotation when the threaded cap 2 is unscrewed or tightened, and avoid damage to the metal braid 6 caused by entanglement.

[0032] An O-ring 9 is provided inside the thread engagement surface 3 after the threaded body 1 and the threaded cap 2 are helically fixed. On the threaded body 1, a lock prevention block 8 is provided at the edge of the threaded cap 2. After the threaded body 1 and the threaded cap 2 are helically fixed, the lock prevention block 8 covers the edge of the threaded cap 2 and is fixed by a fastening bolt 10. The sealing performance between the threaded body and the threaded cap is enhanced. After the threaded body 1 and the threaded cap 2 are connected, they are reinforced by the lock prevention block 8, and the structural connection is more stable.

[0033] Before the device is put into use, one end of the steel ring 5 of the metal braided belt 6 is fixedly connected inside the threaded body 1 through a metal fixing screw 7, a spring washer, and a flat washer, and the other end of the steel ring 5 is fixed inside the threaded cap 2 through a high-strength shoulder screw 4. The threaded cap 2 is screwed and fixed inside the threaded body 1. After the installation is completed, the lock prevention block 8 is fixed by a fastening bolt 10 to reinforce the overall structure, and then the device can be put into use. This device not only solves the problem of the threaded cap 2 falling off but also can solve the problem of static electricity accumulation.

[0034] The embodiments described above are only used to describe the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention should be included within the protection scope determined by the claims of the present invention.
