[0018] 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.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] Traditional plug-in / plug-out testing devices have poor adaptability, especially today when people have increasing demands for larger display screens. They are inadequate for testing displays with different specifications and interfaces. Furthermore, plug-in / plug-out testing is simplistic, requiring each interface to be tested individually, which is inefficient.

[0022] In view of this, the present invention provides a display screen interface plug-in / plug-out testing device. Through the cooperation between the lifting platform, the display screen clamp, and the plug clamp, the height and fixed position of the display screen can be adjusted, and the distance between the plug clamp and the display screen clamp can be adjusted according to the position of the display screen to ensure accurate positioning between the plug and the display screen, so that plug-in / plug-out can be completed smoothly. This is beneficial for matching different sizes of display screens for plug-in / plug-out testing, improving compatibility. At the same time, for some models of display screens, such as those with multiple interfaces on the same side, the plug clamp and clamp rod can be designed to complete the plug-in / plug-out of different interfaces in one go.

[0023] Depend on Figure 1-5 As can be seen, the display interface plug-in / plug-out testing device in this case includes a base 1, a lifting platform 2, a display clamp 3, and a plug clamp 4. The lifting platform 2 is located on the top side of the base 1; two display clamps 3 are provided, both movably connected to the top of the lifting platform 2; the plug clamp 4 is located on one side of the lifting platform 2; wherein, the lifting platform 2, in conjunction with the plug clamp 4, is used to adjust the relative position between the display and the plug and to realize plug-in / plug-out, and the display is fixed to the surface of the lifting platform 2 by the display clamp 3.

[0024] In the specific implementation process, it is worth noting that the lifting platform 2, the display screen clamp 3 and the plug clamp 4 can all be adjusted within a certain range. This allows them to adapt to display screens of different thicknesses and sizes for interface plug-in and unplugging tests. The plug clamp 4 can be designed to allow multiple plugs to be fixed at the same time for plug-in and unplugging tests, such as power cords and display screen connection cables being plugged in and unplugged simultaneously.

[0025] In one feasible approach, please refer to Figure 1 and Figure 2 A first support plate 21 is fixedly connected to the side of the lifting platform 2 near the plug clamp 4. A second support plate 22 parallel to the first support plate 21 is also provided on the side of the lifting platform 2 where the first support plate 21 is fixedly connected. The second support plate 22 is slidably engaged with the lifting platform 2 through the damping slide rail 23.

[0026] In the specific implementation process, it is worth noting that the first support plate 21 and the lifting platform 2 are integrally formed and fixed. The distance between the second support plate 22 and the first support plate 21 can be adjusted by the setting of the damping slide rail 23. The purpose of the first support plate 21 and the second support plate 22 is to support the bottom sides of the display screen respectively after the display screen is placed on the top of the lifting platform 2, so as to ensure the stability of the display screen and facilitate the clamping of the display screen clamp 3. The surface of the damping slide rail 23 is provided with a rubber layer or other materials that increase friction. This is for the purpose of simple fixation of the second support plate 22. Of course, if necessary, screws can be used to fix the second support plate 22 and the lifting platform 2 more effectively.

[0027] Furthermore, threaded tubes 24 fixed to the top of the base 1 are provided on both sides of the bottom of the lifting platform 2. Threaded rods 25 are threadedly connected to the inner wall of the threaded tubes 24, and the top of the threaded rods 25 is rotatably connected to the bottom of the lifting platform 2 through bearings.

[0028] In the specific implementation process, it is worth noting that the threaded tube 24 and the threaded rod 25 work together to adjust the height of the lifting platform 2, so that the height of the display screen socket can be at the same height as the plug fixed by the plug clamp 4.

[0029] In one feasible approach, please refer to Figure 1 , Figure 2 and Figure 3 Both display screen clamps 3 are slidably engaged with the lifting platform 2 via the top slide groove 31 provided on the lifting platform 2. Limiting frames 32 are fixedly connected to the upper side of the two display screen clamps 3 that are far apart from each other. A positioning pin 33 is inserted into the inner wall of the limiting frame 32. A sleeve 34 is sleeved on the lower part of the outer wall of the positioning pin 33. The sleeve 34 is fixed to the outer wall of the display screen clamp 3. A spring 35 is sleeved on the outer wall of the positioning pin 33. The top of the spring 35 is attached to the bottom of the limiting frame 32, and the bottom is pressed against a retaining ring 36. The retaining ring 36 is located above the sleeve 34 and fixed to the outer wall of the positioning pin 33. A friction strip 38 embedded in the surface of the lifting platform 2 is provided below the positioning pin 33.

[0030] In the specific implementation process, it is worth noting that both display screen clamps 3 are L-shaped. This allows for limiting one side of the display screen and clamping and fixing the other two sides, ensuring the stability of the display screen during the insertion and removal test. The position of the two display screen clamps 3 inside the slide groove 31 can be adjusted to ensure that the position of the display screen's socket is aligned with the plug fixed by the plug clamp 4. The limiting bracket 32 ​​and the sleeve 34 cooperate to ensure that the positioning pin 33 is vertically located at the top of the lifting platform 2. The spring 35 provides downward elastic force to the positioning pin 33 through the retaining ring 36 and the limiting bracket 32. In this way, without external force, the bottom of the positioning pin 33 presses against the top of the friction strip 38, thereby fixing the display screen clamp 3. The bottom of the positioning pin 33 and the top of the friction strip 38 can be provided with anti-slip texture, which helps to improve the fixing effect. The friction strip 38 is made of wear-resistant and high-friction material, such as PTFE material. When removing the display screen, manually pull the positioning pin 33 upward, the bottom of the positioning pin 33 separates from the friction strip 38, and the spring 35 is compressed by the retaining ring 36. This allows the position of the display screen clamp 3 inside the slide groove 31 to be moved, making it easy to separate from the display screen.

[0031] The elastic force provided by spring 35 should ensure that there is more than 300 Newtons of static friction between locating pin 33 and friction strip 38, so as to effectively fix the display screen. The specific elastic coefficient of spring 35 and the elastic force it provides should be determined according to the coefficient of friction between locating pin 33 and friction strip 38.

[0032] In one feasible approach, please refer to Figure 3 The inner side of the display fixture 3 is detachably connected to a fitting 37.

[0033] In the specific implementation process, it is worth noting that the fitting part 37 can be made of hard rubber or a hard plastic part designed according to the shape of the display screen. The purpose is to increase the friction between the display screen clamp 3 and the display screen housing and avoid damage to the surface of the display screen. It slides and is attached to the side of the display screen clamp 3 near the display screen and can be replaced according to the actual situation.

[0034] In one feasible approach, please refer to Figure 1 , Figure 4 and Figure 5 The top of the plug clamp 4 is fixedly connected to the clamp rod 41 by bolts. The inner wall of the plug clamp 4 is fixedly connected to the lead screw nut 42. The inner wall of the lead screw nut 42 is threadedly connected to the reciprocating lead screw 43. Both ends of the reciprocating lead screw 43 are rotatably connected to the support 44 through the bearing. The two supports 44 are fixedly connected to the limit rod 46 parallel to the reciprocating lead screw 43. The limit rod 46 passes through the plug clamp 4 and is movably connected to the plug clamp 4. The mounting platform 47 is fixedly connected to the top of the base 1 below the limit rod 46. The end of the reciprocating lead screw 43 away from the lifting platform 2 is fixedly connected to the servo motor 45. The servo motor 45 is fixedly connected to the top of the mounting platform 47.

[0035] In the specific implementation process, it is worth noting that the clamping rod 41 is positioned above the plug clamp 4. After the plug is placed between them, it is clamped and fixed with bolts. The bottom of the clamping rod 41 and the plug clamp 4 can be fitted with anti-slip material or have a special shape design, such as slots, to increase friction between them and the plug. The effective clamping distance between them is relatively long, making it suitable for multi-interface synchronous plugging and unplugging tests on some displays. By correspondingly setting different notches, such as... Figure 5As shown, this design allows for the simultaneous fixing of two or more plug structures, facilitating synchronous plug-in / plug-out testing of multiple interfaces across various display models. The reciprocating screw 43 and screw nut 42 work together to enable the servo motor 45 to drive the plug clamp 4 and clamp rod 41 in reciprocating motion, completing the plug-in / plug-out action. The purpose of the limiting rod 46 is to limit the plug clamp 4, ensuring the effective driving of the plug clamp 4 by the reciprocating screw 43 and screw nut 42. The specific model of the servo motor 45 is not limited, as long as it meets the usage requirements. The distance of the reciprocating movement of the reciprocating screw 43 driving the screw nut 42 is between 2 and 4 centimeters, which can achieve effective plug-in / plug-out while reducing the movement stroke of the plug and improving efficiency.

[0036] Understandably, the mounting platform 47 is fixed to the top of the base 1 with screws. The surface of the base 1 has a strip-shaped opening for screw and nut installation. The bottom of the base 1 has a reserved groove to ensure that the installation of the nut and screw will not affect the flatness of the bottom of the base 1. By fixing the screw and nut at different positions of the strip-shaped opening, the distance between the mounting platform 47 and the display fixture 3 can be adjusted to ensure that the distance between the plug and the display is appropriate, which is conducive to plugging and unplugging tests.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
