[0004] Based on the search of patent numbers, and combined with the shortcomings of existing technologies, the following findings were made;

[0005] The above embodiment only uses guide rods and springs to clamp and fix the two ends of the display screen. However, the springs are elastic, and when the display screen is tapped during the fixing process, it may shake, which will cause the connection between the display screen and the detection position to be unstable and affect the detection effect. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a double-sided pressing device for display screens, which has the advantage of more secure clamping and fixing, and solves the problem of insufficient firmness and stability when fixing the display screen solely with guide rods and springs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-sided pressing device for a display screen, comprising a detection support plate and a fixing mechanism. The detection support plate is provided with a one-way screw and a limiting slide rod. A first cavity is opened inside the detection support plate. Two sets of second sliders are slidably fitted inside the first cavity. Two sets of limiting clamps are slidably fitted on one side wall of each fixing mechanism. The opposite surfaces of the limiting clamps are provided with connection detection heads for inserting display screen interfaces. Two sets of pressure sensors are embedded in one side wall of each fixing mechanism.

[0008] As a preferred embodiment of the present invention, the bottom of the detection support plate is provided with several sets of mounting supports at right angles, and the several sets of mounting supports are respectively fixedly connected to the bottom corner of the detection support plate, and a set of first sliding grooves are provided on one side wall of each set of fixing mechanisms.

[0009] As a preferred embodiment of this utility model, each set of limiting clamps has a set of protective soft pads attached to the opposite surface, and the top of the detection support plate has two sets of second sliding grooves symmetrically opened.

[0010] As a preferred embodiment of this utility model, each set of fixing mechanisms is provided with a set of bidirectional screws inside, and each set of fixing mechanisms is provided with two sets of first sliders attached to the inside, and the two sets of first sliders are threadedly connected to the surface of the bidirectional screws. Each set of first slide grooves is provided with two sets of first support rods slidably attached inside.

[0011] As a preferred embodiment of this utility model, one end of each of the two sets of first support rods is connected to one of the two sets of first sliders, and the other end of each of the two sets of first support rods is connected to one of the two sets of limiting clamps. Each set of fixing mechanisms has a set of adjusting knobs attached to its top.

[0012] In a preferred embodiment of this invention, the first cavity is connected to two sets of second sliding grooves, both ends of the one-way screw are connected to the first cavity, and both ends of the limiting slide rod are fixedly connected to the relative inner walls of the first cavity.

[0013] In a preferred embodiment of this invention, the one-way screw and the limiting slide are symmetrically arranged with the central axis of the first cavity as the center, one set of the second sliders is threadedly connected to the surface of the one-way screw, and the other set of the second sliders is slidably sleeved to the surface of the limiting slide.

[0014] As a preferred embodiment of this utility model, a set of second support rods is slidably fitted inside the second groove, a connecting crossbar is provided inside the first cavity, a second cavity is opened inside the detection support plate, and a drive motor is provided inside the second cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a drive motor to move a one-way screw, causing two sets of second sliders to move on the surfaces of the one-way screw and the limiting slider, respectively. This causes two sets of second support rods to slide inside the two sets of second sliding grooves, while simultaneously driving a set of fixing mechanisms to move on the surface of the detection support plate. The two sets of fixing mechanisms move in opposite directions, and the distance between the two sets of fixing mechanisms can be adjusted according to different screen sizes. This solves the problem of insufficient firmness and stability when fixing the screen using only guide rods and springs, thus improving the stability of the screen during touch-screen operation.

[0017] 2. This utility model uses two sets of limiting clamps to clamp and fix the display screen by moving in opposite directions.

It can be adjusted according to the display screen of different thicknesses. Moreover, when the two sets of limiting clamps clamp the display screen, they do not limit the width of the display screen, which is convenient for clamping and fixing display screens of different sizes.

[0018] 3. This utility model uses two sets of limiting clamps to fix and hold both ends of the display screen. Protective pads are attached to the opposing surfaces of the two sets of limiting clamps to prevent the squeezing force generated during clamping and fixing from damaging the surface of the display screen. Furthermore, through the setting of pressure sensors, both ends of the display screen are attached to and squeezed by several sets of pressure sensors, thereby transmitting the pressure sensor values ​​to the central control device. The central control device controls the drive motor to stop, preventing damage to the display screen when the two sets of fixing mechanisms move, thus improving the safety protection during clamping and fixing.

[0024] 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.

[0025] like Figures 1 to 4 As shown, the present invention provides a display screen dot double-sided pressing device, including a detection support plate 1 and a fixing mechanism 3. Both sets of fixing mechanisms 3 are located on the surface of the detection support plate 1. One set of fixing mechanisms 3 is fixed to the top edge of the detection support plate 1, and the other set of fixing mechanisms 3 is slidably attached to the surface of the detection support plate 1.

[0026] refer to Figure 1 The bottom of the detection support plate 1 is provided with several sets of mounting supports 2 at right angles, and the several sets of mounting supports 2 are respectively fixedly connected to the bottom corner of the detection support plate 1. Each set of fixing mechanisms 3 has a set of first sliding grooves 4 on one side wall, and the central axis of the first sliding grooves 4 coincides with the central axis of the fixing mechanism 3.

[0027] Each set of fixing mechanisms 3 has a side wall that is slidably attached to a limiting clamp 9. A set of protective pads 10 are attached to the surface of each limiting clamp 9. Two sets of second sliding grooves 11 are symmetrically opened on the top of the detection support plate 1.

[0028] As a technical optimization of this utility model, the fixing mechanism 3 and the screen display device can be installed by several sets of mounting supports 2. Two sets of limiting clamps 9 are provided on the opposite surfaces of the two sets of fixing mechanisms 3, which can fix and clamp the two ends of the display screen. Protective pads 10 are attached to the opposite surfaces of the two sets of limiting clamps 9 to prevent the squeezing force generated during clamping and fixing from damaging the surface of the display screen and improve the safety protection during clamping and fixing.

[0029] refer to Figure 2Each set of fixing mechanisms 3 has a set of bidirectional screws 5 inside, and each set of fixing mechanisms 3 has two sets of first sliders 7 attached to the inside, and both sets of first sliders 7 are threaded to the surface of the bidirectional screws 5. Each set of first slide grooves 4 has two sets of first support rods slidably attached inside.

[0030] One end of each of the two sets of first support rods 8 is connected to one of the two sets of first sliders 7, and the other end of each of the two sets of first support rods 8 is connected to one of the two sets of limiting clamps 9. Each set of fixing mechanisms 3 has a set of adjusting knobs 6 attached to its top. Each set of adjusting knobs 6 is located at the top center of the fixing mechanism 3, and each set of adjusting knobs 6 is connected to the top of a set of bidirectional screws 5.

[0031] As a technical optimization of this utility model, the display screen is clamped and fixed by two sets of limiting clamps 9 moving in opposite directions. The operator controls the two sets of first sliders 7 on the surface of the bidirectional screw 5 by turning the adjustment knob 6, so that the two sets of first sliders 7 move in opposite directions and drive the limiting clamps 9 to move, which can be adjusted according to the display screen of different thicknesses.

[0032] refer to Figure 3 The detection support plate 1 has a first cavity 12 inside, which is connected to two sets of second sliding grooves 11. The detection support plate 1 has a one-way screw 13 inside, with both ends of the one-way screw 13 connected to the first cavity 12. The detection support plate 1 has a limiting slide rod 14 inside, with both ends of the limiting slide rod 14 fixedly connected to the opposite inner wall of the first cavity 12.

[0033] The one-way screw 13 and the limiting slide bar 14 are symmetrically arranged with the central axis of the first cavity 12 as the center. Two sets of second sliders 15 are slidably fitted inside the first cavity 12. One set of second sliders 15 is threadedly connected to the surface of the one-way screw 13, and the other set of second sliders 15 is slidably sleeved to the surface of the limiting slide bar 14.

[0034] The second slide groove 11 has a second support rod 16 that slides and fits inside. One end of the second support rod 16 is connected to the second slider 15, and the other end of the second support rod 16 is connected to the bottom end of the fixing mechanism 3. The first cavity 12 has a connecting crossbar 17 inside. Both ends of the connecting crossbar 17 are connected to the second slider 15. The detection support plate 1 has a second cavity 18 inside. The second cavity 18 has a drive motor 19 inside. The output end of the drive motor 19 is connected to one end of the one-way screw 13.

[0035] As a technical optimization of this utility model, by starting the drive motor 19 to drive the one-way screw 13 to move, the two sets of second sliders 15 move on the surfaces of the one-way screw and the limiting slider 14 respectively, thereby driving the two sets of second support rods 16 to slide inside the two sets of second slide grooves 11, while driving a set of fixing mechanisms 3 to move on the surface of the detection support plate 1. The two sets of fixing mechanisms 3 move towards each other, and the distance between the two sets of fixing mechanisms 3 can be adjusted according to the display screen of different sizes.

[0036] refer to Figure 4 The opposing surfaces of the limiting clamps 9 are each provided with a connection detection head 20 for inserting the display screen interface. Each set of fixing mechanisms 3 has two sets of pressure sensors 21 embedded in one side wall, and the two sets of pressure sensors 21 are respectively located on both sides of the first slide groove 4.

[0037] As a technical optimization of this utility model, by setting pressure sensors 21, when a set of fixing mechanisms 3 clamps and fixes one end of the display screen, and then the drive motor 19 is started, so that another set of fixing mechanisms 3 clamps and fixes the other end of the display screen. When the two sets of fixing mechanisms 3 move relative to each other, both ends of the display screen are attached to and squeezed by several sets of pressure sensors 21, thereby transmitting the value of pressure sensors 21 to the central control device. The central control device controls the drive motor 19 to stop, preventing damage to the display screen when the two sets of fixing mechanisms 3 move.

[0038] The working principle and usage process of this utility model are as follows: When in use, a set of fixing mechanisms 3 is attached to one end of the display screen. The operator turns the adjustment knob 6 to move the two sets of limiting clamps 9 to clamp the display screen, and connects the detection head 20 to the display screen interface. Then, the drive motor 19 is started so that the other set of fixing mechanisms 3 clamps and fixes the other end of the display screen. When the two sets of fixing mechanisms 3 move relative to each other, both ends of the display screen are attached to and squeezed by several sets of pressure sensors 21, thereby transmitting the values ​​of the pressure sensors 21 to the central control device. The central control device controls the drive motor 19 to stop. After the display screen is clamped and fixed, the screen is finally turned on.

[0039] In summary, this double-sided pressing device for display screens uses a drive motor 19 to move a one-way screw 13, causing two sets of second sliders 15 to move on the surfaces of the one-way screw and the limiting slider 14, respectively. This causes two sets of second support rods 16 to slide inside two sets of second sliding grooves 11, while simultaneously moving a set of fixing mechanisms 3 on the surface of the detection support plate 1. The two sets of fixing mechanisms 3 move in opposite directions, allowing the distance between them to be adjusted according to different display screen sizes. This solves the problem of insufficient firmness and stability when fixing the display screen solely with guide rods and springs.
