Abstract
Description
Technical Field
[0001] This utility model relates to the field of bolt structure technology, and in particular to a bolt fixing structure that is easy to assemble and disassemble. Background Technology
[0002] During the installation of LED light screens, fixing bolts are generally used to secure the LED light screen to the cabinet or frame. However, during use, there may be situations where the LED light screen needs to be disassembled for maintenance or replacement. Over time, issues such as slot misalignment, slot stripping, slot damage, and slot loss may inevitably occur, requiring re-drilling or even making installation impossible. Therefore, a bolt fixing structure that is easy to disassemble and install is needed to solve this problem. Utility Model Content
[0003] This utility model provides a bolt fixing structure that is easy to assemble and disassemble, in order to solve the problems in the background art.
[0004] This utility model embodiment adopts the following technical solution: a bolt-fixing structure that is easy to assemble and disassemble, including a base and bolts. A magnetic suction plate is provided on one side of the base, allowing the base to be attached to a pre-assembled frame. The other side of the base is used to place an LED light screen to be fixed on the frame. The LED light screen has an opening of the same size as the base, through which the LED light screen is mounted on the base. The bolts are screwed onto the base, and when installed on the base, the bolts can fix the LED light screen located on the base. This solves the problem in the prior art where slots on the frame easily appear during LED light screen installation, leading to inconvenience or even inability to install.
[0005] Furthermore, a placement groove is provided on the side of the base connected to the frame. The magnetic locator is placed in the placement groove, which limits and fixes the magnetic locator to prevent it from falling off the base. When the magnetic locator is in the placement groove, one side of it is at the same horizontal level as the side wall of the base. The placement groove ensures that the magnetic locator has a stable position during installation and use, and will not shift arbitrarily.
[0006] Furthermore, a fixing plate is provided at the top of the magnetic clasp. This fixing plate is made of a resilient metal and can unfold and wrap around or press parallel to the frame when the magnetic clasp is attached to it. When the fixing plate at the top of the magnetic clasp functions to adhere to the frame, whether unfolding and wrapping or pressing parallel to the frame, it significantly improves the tightness of the connection between the magnetic clasp and the frame.
[0007] Furthermore, the bolt has a stud that is screwed to the base, and the rotation of the stud within the base allows the bolt to move as a whole towards one side of the base. A retaining sleeve is also provided on the bolt outside the stud. This retaining sleeve moves synchronously to the outside of the base as the stud moves inward, thus securing the LED light screen located on the base. The retaining sleeve allows for a large contact area with the LED light screen, distributing pressure and reducing the risk of localized damage to the light screen compared to relying solely on the bolt head for pressure.
[0008] Furthermore, a rubber pad is provided on one side of the fixing sleeve located on the base, and the fixing sleeve contacts the LED light screen located on the base through the rubber pad. The presence of the rubber pad provides crucial cushioning protection for the LED light screen.
[0009] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:
[0010] In this invention, a magnetic clasp is ingeniously embedded on one side of the base. This clever design allows the base to be easily attached to a pre-prepared frame. In actual operation, simply bring the base close to the pre-assembled frame, and the powerful magnetic force of the clasp will quickly activate, firmly fixing the base in place. The entire process requires no complicated tools, greatly simplifying the initial installation steps and saving valuable time for subsequent work. The other side of the base is specifically designed to support the LED light screen to be fixed. Bolts, as the key to the overall structure's fastening, are tightly threaded onto the base. As the bolts are gradually screwed into the base and tightened, they generate just the right amount of pressure, firmly securing the LED light screen placed on the base. This method solves the problem in existing technologies where slots on the frame can cause inconvenience or even prevent installation of LED light screens. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0019] Reference Figures 1-4 This utility model embodiment provides a bolt fixing structure that is easy to assemble and disassemble, including a base 1 and a bolt 2. A magnetic suction piece 3 is provided on one side of the base 1, and the base 1 is attached to a pre-assembled frame by adsorption. The other side of the base 1 is used to place the LED light screen to be fixed on the frame. The LED light screen has an opening with the same size as the base 1, and the LED light screen is installed on the base 1 through the opening. The bolt 2 is screwed onto the base 1, and the bolt 2 can fix the LED light screen located on the base 1 when it is installed on the base 1.
[0020] This utility model discloses an ingenious and easily detachable bolt 2 structure, the core components of which include the bolt 2 and the base 1. A magnetic plate 3 is carefully embedded on one side of the base 1. Thanks to this clever design, the base 1 can be easily attached to a pre-prepared frame. In actual operation, simply bring the base 1 close to the pre-assembled frame, and the strong magnetic force of the magnetic plate 3 will quickly take effect, firmly fixing the base 1 in place. The entire process requires no complicated tools, greatly simplifying the initial installation steps and saving valuable time for subsequent operations.
[0021] The other side of base 1 is specifically designed to support the LED light screen to be fixed. The LED light screen has precisely drilled openings that fit perfectly with the dimensions of base 1. This highly precise design ensures that the LED light screen can be accurately embedded into base 1 during installation. Like a jigsaw puzzle finding its perfect piece, the two fit together tightly, effectively preventing misalignment during installation and providing a solid foundation for subsequent fixing work.
[0022] Bolt 2, as the key to fastening the entire structure, is tightly threaded onto base 1. As bolt 2 is gradually screwed into base 1 and tightened, it generates just the right amount of pressure, firmly securing the LED light screen that is steadily placed on base 1. This fixing effect is excellent; even when the LED light screen faces frequent vibrations, minor impacts, or various external forces during daily use, it can still ensure that the light screen remains perfectly still and stable. This method solves the problem in existing technologies where slots on the frame can cause inconvenience or even make installation impossible during LED light screen installation.
[0023] Preferably, a placement groove 4 is provided on the side of the base 1 connected to the frame, and the magnetic absorbing piece 3 is placed in the placement groove 4. The placement groove 4 can limit and fix the magnetic absorbing piece 3 to prevent it from falling off the base 1, and when the magnetic absorbing piece 3 is in the placement groove 4, one side of it is at the same horizontal line as the side wall of the base 1.
[0024] The specially designed placement slot 4 in the base 1 serves multiple functions. Firstly, it provides a dedicated "home" for the magnetic chuck 3, ensuring a stable position during installation and use, preventing it from shifting arbitrarily. This limiting and fixing method effectively avoids installation inconvenience or even equipment malfunctions caused by the magnetic chuck 3 loosening or falling off, greatly improving the reliability of the entire bolt 2 structure in practical applications. Secondly, aligning one side of the magnetic chuck 3 with the side wall of the base 1 creates a neat and concise visual effect, making the connection between the base 1 and the frame appear more orderly. In scenarios where aesthetic design is important, this enhances the overall aesthetics. Simultaneously, the flush design may reduce the probability of dust, debris, and other foreign objects entering the placement slot 4, helping to maintain the stability of the magnetic chuck 3's performance and extend its service life.
[0025] Preferably, the top of the magnetic absorbing piece 3 is provided with a fixing piece 5, which is made of a tough metal material. The fixing piece 5 can unfold and wrap around or be pressed parallel to the frame when the magnetic absorbing piece 3 is attached to the frame.
[0026] When the magnetic accumulator 3 is attached to the frame, the fixing piece 5 at the top of the magnetic accumulator 3 comes into play. Whether it is unfolded and wrapped or pressed parallel to the frame, it can significantly improve the tightness of the connection between the magnetic accumulator 3 and the frame. For some frames with smooth surfaces or special materials, the magnetic force of the magnetic accumulator 3 alone may not provide a sufficiently stable attachment effect. The presence of the fixing piece 5 is like adding an extra "safety lock" to the magnetic accumulator 3.
[0027] For example, in the case of a temporary outdoor LED display screen, in windy weather, the fixing plate 5 can prevent the magnetic plate 3 from loosening or even falling off the frame due to the wind, thus ensuring the safety of the entire device.
[0028] For example, when installing LED lights on some ceiling lights onto the lamp holder, the fixing piece 5 can pass through the hole in the lamp holder and be fixed to the other side of the lamp holder. At this time, the base 1 can also be attracted to the inside of the lamp holder by the magnetic piece 3. This greatly increases the stability of the fixation, and there is no need to make the hole in the lamp holder at a precise position, making the operation more convenient.
[0029] Preferably, the stud 6 on the bolt 2 is screwed to the base 1, and the bolt 2 can be moved toward one side of the base 1 by rotating the stud 6 in the base 1. A fixing sleeve 7 is also provided on the bolt 2 outside the stud 6. The fixing sleeve 7 moves synchronously to the outside of the base 1 when the stud 6 moves toward the reference inward. The LED light screen located on the base 1 can be fixed by the fixing sleeve 7.
[0030] As a crucial component of the bolt 2 structure, the fixing sleeve 7 works in close coordination with the movement of the stud 6. When the stud 6 moves inward toward the base 1, the fixing sleeve 7 moves synchronously outward toward the base 1. This coordinated inward and outward movement significantly enhances the fixing effect. On one hand, the fixing sleeve 7 can make large-area contact with the LED screen, dispersing pressure and reducing the risk of localized damage to the screen compared to relying solely on the head of the bolt 2. On the other hand, the synchronous movement of the fixing sleeve 7 makes the entire fixing process smoother and more uniform, avoiding the problem of screen tilting or insecure fixing due to unilateral force, ensuring that the LED screen remains horizontal and stable after installation.
[0031] Preferably, the fixing sleeve 7 is provided with a rubber pad 8 on one side of the base 1, and the fixing sleeve 7 contacts the LED light screen located on the base 1 through the rubber pad 8.
[0032] The rubber pad 8 provides crucial cushioning protection for the LED light screen. During the process of the fixing sleeve 7 transferring the tightening force of the bolt 2 to the LED light screen, the rubber's excellent elasticity absorbs and disperses some of the pressure, effectively preventing damage to the light screen due to excessive compression. Especially in scenarios requiring frequent disassembly and assembly of LED light screens, such as temporary display systems for exhibitions and stage performances, where precise control of the force applied during each installation may be difficult, the rubber pad 8 acts like a "safety shield," ensuring the light screen remains undamaged during repeated fixing and extending its lifespan.
[0033] Rubber material itself has a high coefficient of friction. When the fixing sleeve 7 contacts the LED light screen through the rubber pad 8, the friction between the two is significantly increased compared to direct metal-to-metal contact. This allows the LED light screen to remain in place after installation, even under slight external vibrations or shaking, thanks to the friction provided by the rubber pad 8, preventing displacement. For example, in outdoor advertising LED light screen installation scenarios, it often encounters wind, sun, and rain. The high friction of the rubber pad 8 helps to firmly fix the light screen to the base 1, ensuring the stability and continuity of the advertising display.
[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
