Description

Technical Field

[0001] This utility model relates to the technical field of screen mounting mechanisms, and in particular to a lightweight screen fixing device. Background Technology

[0002] With the increasing popularity of mobile work and smart homes, the use of lightweight screen devices such as tablets and small monitors is becoming more and more common. To facilitate viewing and operation, these devices often need to be fixed in specific locations, such as desktops, walls, or stands.

[0003] Existing fixing methods mostly employ slot-type or clamp-type designs. Slot-type structures are generally more complex, making screen installation and removal less convenient; while ordinary clamp-type structures often only provide clamping force in one direction, resulting in insufficient stability, and the screen is easily shaken or even detached due to accidental touches. In addition, most fixing devices are designed for specific screen models or sizes, lacking versatility.

[0004] Currently, with the widespread use of portable electronic devices, the demand for securing lightweight screens such as tablets and small displays is increasing. Existing securing devices mostly employ traditional clamping structures or snap-on designs, resulting in bulky overall structures and large dimensions, particularly in the horizontal and vertical directions. This not only occupies excessive space after installation but also makes them difficult to store when not in use, impacting the tidiness and portability of the environment. Furthermore, most devices only provide clamping force in one direction or rely on rigid slots for limiting movement, failing to effectively adapt to screens of varying thicknesses and sizes. This leads to a small clamping contact area, uneven force distribution, insufficient stability and reliability, and screens susceptible to shaking, tilting, or even slippage due to external forces, posing safety hazards.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a lightweight screen fixing device to solve the above problems.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and for the convenience of those skilled in the art to understand it. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

A telescopic arm is slidably connected in each guide groove. The upper end of the telescopic arm is provided with an upper pressure plate perpendicular to the mounting surface of the mounting plate, and its lower end is connected to the lower end of the corresponding guide groove in the inclined direction through a tension spring. The lower end of the mounting plate is provided with two symmetrically arranged lower support plates, each lower support plate being rotatably connected to the mounting plate through a pivot. A torsion spring is provided on the pivot to provide an upward reset force for the lower support plate. The upper pressure plate and the lower support plates together constitute a first locking mechanism for clamping and fixing the lightweight screen from top to bottom.

[0009] Preferred technical solution: The mounting plate includes a front housing and a rear housing that can be interlocked, and a guide groove is provided on the inner side of the rear housing.

[0010] Preferred technical solution: The lower end of the telescopic arm is provided with a first spring connecting seat, the lower end of the guide groove is provided with a second spring connecting seat, and the two ends of the tension spring are respectively hooked to the first spring connecting seat and the second spring connecting seat.

[0011] Preferred technical solution: The telescopic arm includes a rear shell and a front shell that are interlocked by a snap-fit ​​structure, and a first spring connecting seat is located in the internal area formed by the rear shell and the front shell.

[0012] Preferred technical solution: The lower ends of the two guide grooves are connected to each other and form a V-shaped groove structure. The second spring connecting seat is located at the bottom of the V-shaped groove structure. The first spring connecting seats of the two telescopic arms are respectively connected to the second spring connecting seat through tension springs.

[0013] Preferred technical solution: The upper pressure plate is provided with a guide tube, the axis of which is perpendicular to the mounting surface of the mounting plate; a rotating clamping block that can move along its axis and rotate around its axis is provided inside the guide tube; the connecting end of the rotating clamping block is connected to the bottom of the guide tube by a compression spring, the compression spring provides the rotating clamping block with a reset force in the direction of the mounting plate, and the rotating clamping block and the mounting plate together constitute a second locking mechanism for clamping and fixing the lightweight screen from the front and back.

[0014] Preferred technical solution: The tension spring is a flat wire tension spring.

[0015] Preferred technical solution: The mounting surface of the mounting plate is provided with a storage groove, and the lower support plate can be flipped into the storage groove.

[0016] Preferred technical solution: The front end of the lower support plate is provided with a raised anti-detachment structure.

[0017] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] This invention achieves automatic centering and stable clamping of the screen through the sliding cooperation of symmetrically arranged inclined guide grooves and telescopic arms, resulting in a reasonable structure and convenient operation. Specifically, in the non-use state, the lower support plate can be flipped and stored in the storage groove on the mounting surface of the mounting plate. Under the action of the tension spring, the telescopic arm retracts inward and downward along the guide groove, making the overall device extremely compact, significantly reducing both the lateral and longitudinal dimensions, facilitating carrying and storage. In use, the lower support plate quickly unfolds under the action of the torsion spring, and the telescopic arm automatically slides upward and outward as the screen is placed in, forming a clamping structure significantly wider than the mounting plate itself. This accommodates screens of different sizes, greatly improving usability and environmental adaptability. Attached Figure Description

[0032] like Figures 1 to 5As shown, a lightweight screen fixing device includes a mounting plate 1. The mounting surface of the mounting plate 1 has two symmetrically arranged guide grooves 2, each extending outwards and upwards from the mounting surface of the mounting plate 1, respectively. A telescopic arm 3 is slidably connected in each guide groove 2. The upper end of the telescopic arm 3 is provided with an upper pressure plate 4 perpendicular to the mounting surface of the mounting plate 1, and its lower end is connected to the lower end of the corresponding guide groove 2 in the inclined direction via a tension spring 5. Two lower support plates 6 are symmetrically provided at the lower end of the mounting plate 1. Each lower support plate 6 is rotatably connected to the mounting plate 1 via a pivot 7, and a torsion spring 8 on the pivot 7 provides an upward restoring force for the lower support plate 6. The upper pressure plate 4 and the lower support plates 6 together constitute a first locking mechanism for clamping and fixing the lightweight screen upwards and downwards. It should be noted that, normally, when the lower support plate 6 is rotated downwards to its limit position, the supporting surface of the lower support plate 6 is perpendicular to the mounting surface of the mounting plate 1; in some embodiments, it may also be tilted downwards or upwards.

[0033] In use, the lower edge of the lightweight screen is placed on the lower support plate 6. The weight of the screen causes the lower support plate 6 to flip down. When it flips to the limit position, the lower support plate 6 stops moving and lifts the lower edge of the lightweight screen. At the same time, the tension spring 5 pulls the telescopic arm 3 to slide along the guide groove 2, so that the upper pressure plate 4 presses down to tighten the upper edge of the lightweight screen, achieving automatic centering and stable clamping.

[0034] In some embodiments, the mounting plate 1 is composed of a front housing 11 and a rear housing 12 that are fastened together, and the guide groove 2 is provided inside the rear housing 12. The structure is compact and easy to manufacture and assemble.

[0035] In some embodiments, the lower end of the telescopic arm 3 is provided with a first spring connecting seat 31, and the lower end of the guide groove 2 is provided with a second spring connecting seat 21. The two ends of the tension spring 5 are respectively hooked to the two, which makes the connection reliable and easy to replace.

[0036] In some embodiments, the telescopic arm 3 is connected to the rear shell and the front shell by a snap fastener, and the first spring connecting seat 31 is located inside to protect the spring connection point and extend its service life.

[0037] In some embodiments, the lower ends of the two guide grooves 2 are connected in a V-shape, and the second spring connecting seat 21 is located at the bottom of the V-shape. The tension springs 5 ​​of the two telescopic arms 3 share a common connection point, making the structure simpler and the force more balanced.

[0038] In some embodiments, the upper pressure plate 4 is provided with a guide tube 41, which contains a rotating clamping block 42. A compression spring 43 provides forward pressure, which together with the mounting plate 1 clamps the lightweight screen, enhancing the placement stability of the lightweight screen in the front-back direction.

[0039] In some embodiments, the tension spring 5 is a flat wire spring, which provides a smoother elastic force and reduces swaying.

[0040] In some embodiments, the mounting surface of the mounting plate 1 is provided with a storage groove 13, and the lower support plate 6 can be flipped up and stored therein for easy carrying and storage.

[0041] In some embodiments, the front end of the lower support plate 6 is provided with a raised anti-slip structure 61 to prevent the lightweight screen from slipping off and improve safety.

[0042] The method of use and principle of this utility model are as follows:

[0043] When not in use, the lower support plate 6 flips into the storage slot 13, and the telescopic arm 3 retracts inward and downward along the guide slot 2 under the action of the tension spring 5, so that the whole device is in a compact state.

[0044] In use, the screen is placed on the unfolded lower support plate 6. The weight of the screen causes the lower support plate 6 to tilt downwards, while the tension spring 5 pulls the telescopic arm 3 to slide along the guide groove 2, causing the upper pressure plate 4 to press down and tighten the upper edge of the screen. Under the action of the compression spring 43, the rotating clamping block 42 presses the lightweight screen against the mounting plate 1, achieving stable clamping in multiple directions.

[0045] After the screen is removed, the lower support plate 6 automatically flips into the storage slot 13 under the action of the torsion spring 8, and the telescopic arm 3 retracts and resets under the action of the tension spring 5, restoring its compact state.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
