Description

Technical Field

[0001] This utility model relates to the field of display screen installation technology, specifically a magnetic quick-connect display screen fixing screw. Background Technology

[0002] In the field of display screen installation, traditional fixing screws have problems such as low installation efficiency and difficulty in alignment. With the popularization of LED displays, advertising screens and other equipment, the frequent disassembly and assembly needs have prompted the research and development of rapid fixing technology.

[0003] In existing technologies, the excessively strong attraction between the magnetic head and the mounting surface can significantly increase the resistance when tightening screws. This not only increases the difficulty of operation for installers but may also cause the screwdriver to slip, reducing installation efficiency. When in a state of strong magnetic attraction for a long time, the screws are prone to gradually loosening due to friction between the magnetism and the metal surface under vibration, making it difficult to ensure the stability of the display screen. Therefore, we propose a magnetic quick-connection display screen fixing screw. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic quick-connection screw for fixing a display screen, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic quick-connection display screen fixing screw, comprising a nut, a stud on the nut, and a nut on the stud, and further comprising:

[0006] An adjustment assembly includes an inner cavity formed inside a nut, a rotating rod rotatably connected inside the inner cavity, and a magnetic shielding sheet connected to the rotating rod;

[0007] A drive assembly includes a sliding block disposed within an inner cavity, a telescopic block slidably connected to the top of the sliding block, the top of the telescopic block being rotatably connected to one end of the bottom of a rotating rod, and a connecting rope connected to the sliding block, with the end of the connecting rope away from the sliding block located outside the inner cavity.

[0008] Furthermore, a limiting component is provided on the side of the inner cavity near the sliding block. The limiting component includes a slide rail, and the sliding block is slidably connected to the slide rail.

[0009] By adopting the above technical solution, by setting a limiting component, the sliding block can be limited during movement to prevent its movement trajectory from deviating.

[0010] Furthermore, a first spring is connected between the sliding block and the inner wall of the slide rail.

[0011] The above technical solution is adopted: by setting a first spring, when the connecting rope is released, the sliding block drives the magnetic shielding sheet to automatically reset through the elastic force of the first spring.

[0012] Furthermore, the nut is provided with a locking assembly, which includes a retaining ring with a retaining groove. A second spring is connected inside the retaining groove, and a hook is connected to the second spring. The hook is slidably connected inside the retaining groove.

[0013] The above technical solution is adopted: by setting up a locking component, when the screw is screwed in, the retaining ring is embedded in the annular groove of the screw hole, and the hook claw increases the friction to form a mechanical lock.

[0014] Furthermore, the nut is provided with a magnetic suction assembly, which includes a magnetic suction head with a threaded section and a threaded groove in the inner cavity, and the magnetic suction head is threadedly connected to the inner cavity.

[0015] The above technical solution allows for quick installation and replacement of the magnetic head by setting up a magnetic suction component.

[0016] Furthermore, the nut has a cross groove.

[0017] The above technical solution is adopted: by setting a cross-shaped groove, it is easy to use tools such as screwdrivers for tightening and installation.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting an adjustment component, the magnetic shielding sheet can be rotated. When the magnetic shielding sheet is rotated to 90 degrees, it completely covers the magnet, weakening the magnetic field strength. This greatly reduces the resistance during the screw-in process, solving the problem in the prior art where the excessively strong attraction between the magnetic head and the mounting surface leads to a significant increase in resistance when screwing in the screw. This not only increases the difficulty of operation for installers but may also cause the screwdriver to slip, reducing installation efficiency. Furthermore, in the long-term state of strong magnetic attraction, the screw is prone to gradually loosening due to friction between the magnet and the metal surface under vibration, making it difficult to ensure the stability of the display screen.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a magnetic quick-connection display screen fixing screw, including a nut 1, a stud 2 provided on the nut 1, and a nut 3 provided on the stud 2. The nut 1 has a cross groove 8, and also includes:

[0035] Adjustment component 4 includes an inner cavity 41 opened inside the nut 1, a rotating rod 42 rotatably connected inside the inner cavity 41, and a magnetic shielding sheet 43 connected to the rotating rod 42;

[0036] Drive assembly 5 includes a sliding block 51 disposed in the inner cavity 41, a telescopic block 52 slidably connected to the top of the sliding block 51, the top of the telescopic block 52 being rotatably connected to one end of the bottom of the rotating rod 42, and a connecting rope 53 connected to the sliding block 51, with one end of the connecting rope 53 away from the sliding block 51 located outside the inner cavity 41.

[0037] Specifically, before screwing in the screw, the connecting rope 53 is pulled to move the sliding block 51. During the sliding process, the telescopic block 52 will extend and retract within the sliding block 51, thereby causing the magnetic shielding sheet 43 to rotate 90 degrees in the inner cavity 41 through the rotating rod 42 to completely cover the magnet. The magnetic field strength is weakened, and the resistance during the screwing process will be greatly reduced.

[0038] Furthermore, such as Figure 1 As shown: The nut 1 is provided with a magnetic suction assembly 9, which includes a magnetic suction head 91. The magnetic suction head 91 has a threaded section 92 and a threaded groove in the inner cavity 41. The magnetic suction head 91 is threadedly connected to the inner cavity 41. Before operation, the magnetic suction head 91 is screwed into the inner cavity 41 through the threaded section 92 and the threaded groove in the inner wall of the inner cavity 41.

[0039] The above solution also requires that the sliding block 51 be limited during movement, and the magnetic shielding sheet 43 should be able to automatically spring back to its original position. Figure 5 As shown: A limiting component 6 is provided on one side of the inner cavity 41 near the sliding block 51. The limiting component 6 includes a slide rail 61, and the sliding block 51 is slidably connected to the slide rail 61. A first spring 62 is connected between the sliding block 51 and the inner wall of the slide rail 61. The sliding block 51 will slide in the slide rail 61, limiting the movement trajectory of the sliding block 51. When the connecting rope 53 is released, the sliding block 51 will drive the magnetic shielding sheet 43 to automatically spring back to the horizontal direction through the elastic force of the first spring 62.

[0040] The above solutions also include the requirement that the screws be locked after being screwed in to prevent them from loosening due to vibration. Figure 1 and Figure 2 As shown: The nut 1 is provided with a locking component 7, which includes a retaining ring 71. The retaining ring 71 has a retaining groove 72. A second spring 73 is connected in the retaining groove 72. A hook 74 is connected to the second spring 73. The hook 74 is slidably connected in the retaining groove 72. When screwed into the threaded hole, the hook 74 will retract into the retaining groove 72. Then, the other end of the hook 74 will contact the hole arm to increase the friction, thereby locking.

[0041] like Figure 1 - Figure 5 As shown:

[0042] Before operation, the magnetic head 91 is screwed into the inner cavity 41 through the threaded section 92 and the threaded groove on the inner wall of the inner cavity 41. Then, the connecting rope 53 is pulled to drive the sliding block 51 to slide. During the sliding process, the telescopic block 52 will extend and retract within the sliding block 51, thereby driving the magnetic shielding plate 43 to rotate 90 degrees in the inner cavity 41 through the rotating rod 42 to completely cover the magnet. The magnetic field strength is weakened, and the resistance during the screwing process will be greatly reduced. When screwed into the threaded hole, the hook 74 will retract into the slot 72. Then, the other end of the hook 74 will contact the hole arm to increase the friction and thus lock in place. After the screw is in place, the connecting rope 53 is released, and the sliding block 51 will automatically spring back to the horizontal direction through the elastic force of the first spring 62, so that the magnetic field strength is restored and the magnetic connection is achieved.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
