Description

Technical Field

[0001] This utility model relates to the field of display screen fixing technology, and in particular to a display screen fixing structure. Background Technology

[0002] With the continuous development of display technology, displays have been widely used in various scenarios in work and life. In order to meet the viewing habits and environmental requirements of different users, the brackets or structures used to fix the displays usually need to have angle adjustment functions, such as tilt angle adjustment.

[0003] In existing technologies, most structures for adjusting the angle of a display screen use friction damping or bolt locking. These structures typically have two contacting friction surfaces at the pivot point. By tightening the bolt, the normal pressure between the two friction surfaces is increased, thereby generating a sufficiently large frictional force to fix the display screen at any adjusted angle.

[0004] The adjustment process is inconvenient, requiring users to use tools to loosen or tighten the locking bolts. It is also difficult to precisely control the tightening force, which may result in the bolts not locking properly or locking completely. The locking reliability is poor. The weight of the display screen itself will continuously apply torque to the friction structure. After long-term use, the friction surface is prone to wear, leading to a decrease in friction. This results in frequent screen nodding and instability in maintaining the angle, which seriously affects the user experience.

[0005] Therefore, this utility model proposes a display screen fixing structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing display screen fixing structure, such as inconvenient operation and laborious adjustment of the angle adjustment mechanism, and the fact that the locking method mostly relies on friction, resulting in unreliable locking after long-term use and easy "nodding" and drooping of the display screen, this utility model aims to provide a display screen fixing structure with improved structure that can effectively solve the above problems.

[0007] This utility model provides a display screen fixing structure, including: a rear shell and a front frame; an angle adjustment mechanism for adjusting the angle of the rear shell; and a quick-release mechanism for detachably fixing the front frame to the rear shell.

[0008] The angle adjustment mechanism includes a flexible cross arm, with a connecting seat and a height adjustment rod rotatably connected to each end of the cross arm. A second rotating groove is provided on the rear shell. The connecting seat and the height adjustment rod are rotatably installed in the second rotating groove via a rotating shaft. A first serrated ring and a second serrated ring are provided between the connecting seat and the cross arm and engage with each other. A cam handle with an eccentric rotating shaft is also rotatably connected to the cross arm. The rotation of the cam handle is used to push the cross arm to deform through its eccentric rotating shaft, thereby controlling the first serrated ring and the second serrated ring to separate or engage and lock with each other.

[0009] Preferably, the quick-installation mechanism includes a rotating column rotatably connected to the rear shell and a connecting rod fixedly connected to the front frame. A fixed ball is fixedly connected to the end of the connecting rod. The rotating column has a rod groove for the connecting rod to pass through and a ball groove for accommodating the fixed ball. This structure allows the rotating column to selectively block or open the opening of the ball groove by rotating itself and using its outer peripheral column wall, thereby locking or releasing the fixed ball and greatly simplifying the installation steps.

[0010] Preferably, in order to facilitate the installation of the quick-installation mechanism, a reserved groove is provided on the front frame corresponding to the position of the rotating column to guide the insertion of the rotating column, and a rotating groove is provided on the rear shell corresponding to the position of the rotating column for its rotational installation, so that the rotating column can rotate within the rotating groove.

[0011] Preferably, in order to improve the rotation feel of the rotating column and prevent it from rotating accidentally, a damping bushing for providing rotational damping is provided between the outer peripheral wall of the rotating column and the inner wall of the rotating groove. The damping bushing can be made of materials such as rubber or engineering plastics, and provides a stable damping feel for rotation through friction.

[0012] Preferably, in order to provide sufficient movement space for the connecting rod when the rotating column is locked, an annular groove communicating with the rod groove is provided inside the rotating column. When the rotating column rotates, the main body of the connecting rod can rotate in the annular groove, thus avoiding structural interference.

[0013] Preferably, in order to achieve precise meshing and positioning, the first serrated ring is fixedly connected to the adjacent end of the connecting seat and the height adjusting rod, and the second serrated ring is fixedly connected to the side of the cross arm facing the connecting seat and the height adjusting rod. The two serrated rings are arranged face to face to ensure reliable meshing when the cross arm is under pressure.

[0014] Preferably, in order to achieve effective driving of the cross arm by the cam handle, the cam handle is rotatably connected to the cross arm via the rotating shaft. The rotating shaft serves as a common rotating shaft, simultaneously bearing the rotation of the connecting seat or height adjustment rod and the rotation of the cam handle.

[0015] Preferably, the rear shell is a shell with a recess for accommodating the display body, and the recess design provides a basic mounting platform and back support for the display.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a quick-installation mechanism, uses the rotation of the rotating column to drive the outer peripheral column wall to seal or open the ball groove, thereby realizing the limitation or release of the fixed ball. It solves the problem that the installation of the display screen usually relies on multiple screws for fixing, which is cumbersome, time-consuming and easy to lose parts. It achieves a simple and quick installation process, intuitive operation and stable and reliable connection.

[0017] 2. This utility model, by setting an angle adjustment mechanism, uses an eccentrically designed cam handle to drive an elastic cross arm, thereby controlling the engagement or disengagement of the mutually cooperating sawtooth rings. This solves the problems of the existing technology, which often uses friction locking or bolt fastening for display screen angle adjustment, which is laborious to adjust, inaccurate in positioning, and prone to loosening and sagging after long-term use. It achieves labor-saving and convenient angle adjustment, accurate positioning, and firm and reliable locking.

[0018] 3. This utility model increases the damping feel during rotation by adding a damping bushing between the rotating column and the rotating groove of the quick-assembly mechanism. At the same time, the angle adjustment mechanism uses the rigid engagement of a sawtooth ring for locking, which solves the reliability problems of the prior art, such as the easy occurrence of accidental displacement of moving parts due to vibration and the unstable locking state. This improves the overall structural operation quality and long-term reliability. Attached Figure Description

[0021] 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.

[0022] Example: Please refer to Figures 1 to 6 This utility model provides a display screen fixing structure, which aims to solve the problems of cumbersome display screen installation process, inconvenient angle adjustment operation and unreliable locking in the prior art.

[0023] like Figure 1 and Figure 2 As shown, a display screen fixing structure includes a rear shell 1, a front frame 4, a quick-release mechanism 2 disposed between the rear shell 1 and the front frame 4, and an angle adjustment mechanism 3 connected to the rear shell 1. The rear shell 1 is a shell with a groove for accommodating the display screen body. The front frame 4 cooperates with the rear shell 1 to fix the display screen inside it. The quick-release mechanism 2 is used to realize the quick fixing and separation between the front frame 4 and the rear shell 1. The angle adjustment mechanism 3 is used to support and adjust the overall angle of the rear shell 1.

[0024] like Figure 5 and Figure 6As shown, the angle adjustment mechanism 3 is the core for achieving convenient angle adjustment and reliable locking. Specifically, it includes a flexible crossarm 301. Connecting seats 303 and height adjustment rods 304 are rotatably connected to both ends of the crossarm 301. A second rotation groove 302 is provided on the rear housing 1. The connecting seats 303 and height adjustment rods 304 are rotatably mounted inside the second rotation groove 302 via a rotating shaft 307, allowing the crossarm 301 to swing and adjust around the axis of the rotating shaft 307. On the opposite surfaces of the connecting seats 303 and the crossarm 301, there are... The sawtooth ring 305 and sawtooth ring 306 are used for angle locking. The teeth of sawtooth ring 305 and sawtooth ring 306 are matched with each other. A cam handle 308 with an eccentric rotating shaft is also rotatably connected to the cross arm 301. The cam handle 308 is rotatably connected to the cross arm 301 through the rotating shaft 307. When the cam handle 308 is rotated, the profile of its eccentric rotating shaft will push the cross arm 301 to produce a slight elastic deformation. This deformation will drive sawtooth ring 306 to disengage from or tightly engage with sawtooth ring 305, thereby realizing the unlocking and locking of the angle adjustment function.

[0025] Please refer to Figure 3 and Figure 4 The quick-release mechanism 2 includes a rotating column 204 rotatably mounted on the rear shell 1 and a connecting rod 203 fixedly connected to the front frame 4. The end of the connecting rod 203 is provided with a spherical fixed ball 209 by a fixed connection. The rotating column 204 is a generally cylindrical component with an annular groove 207 inside for accommodating the connecting rod 203 during rotation. The outer peripheral wall of the rotating column 204 is also provided with a rod groove 206 that communicates with the annular groove 207. The width of the rod groove 206 is sufficient for the connecting rod 203 to pass through. At one end of the rotating column 204 near the rod groove 206, a ball groove 205 is recessed for accommodating the fixed ball 209. The ball groove 205 communicates with the rod groove 206 and its opening faces the end face of the rotating column 204.

[0026] During assembly, the front frame 4 has a reserved slot 201 for inserting the rotating column 204, and the rear shell 1 has a corresponding rotating slot 202 for rotating the rotating column 204. When the front frame 4 and the rear shell 1 are aligned, the rotating column 204 is inserted into the reserved slot 201, and the rotating column 204 is rotated to a specific angle so that the rod groove 206 is aligned with the connecting rod 203. At this time, the connecting rod 203 passes through the rod groove 206, and the fixed ball 209 at its end falls into the ball groove 205. Then, the rotating column 204 is rotated 180 degrees, and the outer peripheral column wall of the rotating column 204 will block the opening of the ball groove 205, thereby restricting the fixed ball 209 inside the ball groove 205 and preventing it from coming out. The main body of the connecting rod 203 is in the clearance space provided by the annular groove 207. This matching structure of the rotating column blocking the opening of the ball groove 205 ensures the firm and reliable connection between the front frame 4 and the rear shell 1 and the convenient and efficient disassembly and assembly.

[0027] As a preferred embodiment, in order to enhance the feel and stability of the rotating column 204 during rotation and prevent it from rotating unexpectedly when not locked, a damping bushing 208 for providing rotational damping is provided between the outer peripheral wall of the rotating column 204 and the inner wall of the rotating groove 202. The damping bushing 208 surrounds the outer periphery of the rotating column 204, and its material can be rubber or engineering plastic with a certain coefficient of friction and elasticity.

[0028] As another preferred embodiment, to more clearly define the installation and movement relationship of the angle adjustment mechanism 3, please refer to... Figure 5 and Figure 6 The first serrated ring 305 is fixedly connected to the adjacent end of the connecting seat 303 and the height adjusting rod 304, while the second serrated ring 306 is fixedly connected to the side of the cross arm 301 facing the connecting seat 303 and the height adjusting rod 304, thereby ensuring that the two serrated rings can accurately engage or disengage when the cross arm 301 is pushed.

[0029] In another preferred embodiment, in order to clarify the force transmission path of the cam handle 308, the cam handle 308 is rotatably connected to the cross arm 301 via a rotating shaft 307. The rotating shaft 307 passes through the cross arm 301 and the cam handle 308, so that the rotational torque of the cam handle 308 can be effectively transmitted to the cross arm 301.

[0030] Working principle: In use, first place the display screen in the groove inside the back shell 1, then rotate the rotating column 204 in the multiple rotating slots 202 with a hex wrench so that the rod groove 206 on the rotating column 204 is vertically upward. Since the rotating column 204 is provided with a damping bushing 208 on the outside, the rotating column 204 can remain fixed after rotating in the rotating slot 202. Then align the front frame 4 with the back shell 1 and insert the multiple rotating columns 204 into the corresponding reserved slots 201. During this process, multiple fixing balls 209 will enter the corresponding ball grooves 205, and the connecting rod 203 will enter the corresponding annular groove 207 through the rod groove 206. Then rotate the multiple rotating columns 204 clockwise by 180 degrees so that the rod groove 206 is vertically downward, locking the fixing balls 209 and preventing the connecting rod 203 from coming off the rotating column 204. The quick-installation mechanism 2 solves the problem of complicated operation of installing the display screen in the prior art. Furthermore, when the angle of the display screen needs to be adjusted, rotating the two cam handles 308 so that the cam handles 308 and the corresponding rotating shafts 307 are aligned, the pivot point of the cam handles 308 is close to the cross arm 301 due to the eccentric design of the pivot. Under the elastic action of the cross arm 301 itself, the forks at both ends will open. At this time, the first serrated ring 305 and the second serrated ring 306 separate. Since the connecting seat 303 and the height adjustment rod 304 are rotatably connected to the corresponding rotating shafts 307, the cross arm 307 can be rotated. 01, causing the height adjustment rod 304 and the connecting seat 303 to rotate within the rotating groove 302, thereby adjusting the angle of the cross arm 301 and the connecting seat 303. After the angle adjustment is completed, the cam handle 308 is rotated so that the cam handle 308 is pressed tightly against the cross arm 301. During this process, the pivot point of the cam handle 308 is moved away from the cross arm 301, thereby causing multiple serrated rings 306 to press against the opposing serrated ring 305. The serrations are used for limiting the position, thus solving the problem of complicated operation of adjusting the display screen angle in the prior art through the angle adjustment mechanism 3.
