The connecting member 322 is connected to the first operating member 323 through the first locking member 324, and the first locking member 324 may be a bent connecting rod; since the hinge axis of the first locking member 324 and the first operating member 323 and the rotation axis of the first operating member 323 are spaced apart along the extension direction of the first operating member 323, when the first operating member 323 rotates, it can drive the first locking member 324 and the connecting member 322 to move closer to or away from the mounting portion 11, thereby driving the hook assembly 31 to move; at the same time, the hinge axis of the first locking member 324 and the first operating member 323 will rotate around the first operating member. The rotation axis of the first operating member 323 rotates, and when the hinge axis of the first locking member 324 and the first operating member 323 rotates to the side where the rotation axis of the first operating member 323 is away from the mounting portion 11 and is located on the side where the rotation axis of the first operating member 323 is close to the base 1, the first operating member 323 is locked in a position away from the mounting portion 11, that is, the first operating member 323 will remain in a position away from the mounting portion 11 without external force operation. At this time, the hook 311 of the hook-pull assembly 31 remains in a state of pulling the buckle 201 of the screen frame 200 apart, realizing a self-locking function. In this way, by setting the first locking member 324, the first operating member 323 can be locked in a position away from the mounting portion 11, and then the hook 311 of the hook-pull assembly 31 can be locked in a state of pulling the buckle 201 of the screen frame 200 apart, so that after completing the pulling action of the buckle 201, you can let go without continuously operating the first operating member 323, which is convenient and labor-saving, simple and easy to use, and conducive to improving assembly stability.

[0058] In some embodiments, referring to Figures 1 and 3 to 5, the fixing mechanism 2 includes a first fixing member 21 and a second fixing member 22. Along the first direction, the first fixing member 21 and the second fixing member 22 are respectively arranged on opposite sides of the mounting portion 11, and the first fixing member 21 and the second fixing member 22 are used to cooperate with the opposite sides of the fixed screen frame 200.

[0059] For example, along the first direction, the first fixing member 21 is arranged on one side of the mounting portion 11 close to the hook assembly 31, and the second fixing member 22 is arranged on the other side opposite to the mounting portion 11; the first fixing member 21 and the second fixing member 22 can be used to fix the screen frame 200 by pressing the surface of the screen frame 200 away from the base 1, or can be used to fix the screen frame 200 by clamping the two opposite sides of the screen frame 200, and there is no limitation here. In this way, the first fixing member 21 and the second fixing member 22 cooperate to fix the opposite sides of the screen frame 200, so that the force on the screen frame 200 is balanced, the fixing of the screen frame 200 is more stable and reliable, and the damage to the screen frame 200 is reduced, thereby improving the assembly quality.

[0060] In some embodiments, referring to Figures 1 and 3 to 5, the number of first fixing members 21 is at least two, and at least two first fixing members 21 are arranged at intervals along the second direction; the number of second fixing members 22 is at least two, and at least two second fixing members 22 are arranged at intervals along the second direction; the second direction is perpendicular to the first direction.

[0061] For example, the number of the first fixing members 21 is two, three or four, and the number of the second fixing members 22 is two, three or four, and the number of the first fixing members 21 and the number of the second fixing members 22 may be the same or different, and there is no limitation here. For example, the first direction is parallel to the length direction of the mounting portion 11, the second direction is parallel to the width direction of the mounting portion 11, two first fixing members 21 are spaced apart on one width direction side of the mounting portion 11, and two second fixing members 22 are spaced apart on another width direction side of the mounting portion 11. In this way, by providing a plurality of first fixing members 21 and a plurality of second fixing members 22, the screen frame 200 can be fixed at multiple points, which is more stable and reliable, and the force on the screen frame 200 is dispersed, reducing the force on a single point, and the screen frame 200 is not easily damaged, thereby improving the assembly quality.

[0062] In some embodiments, the first fixing member 21 and the second fixing member 22 are configured to respectively abut against two opposite sides of the screen frame 200 along the first direction to cooperate in clamping and fixing the screen frame 200 .

[0063] For example, the first fixing member 21 abuts against the side of the screen frame 200 close to the hook assembly 31 along the first direction, and the second fixing member 22 abuts against the side of the screen frame 200 away from the hook assembly 31 along the first direction, so that the first fixing member 21 and the second fixing member 22 cooperate to clamp and fix the screen frame 200. Since the edge of the screen frame 200 is narrow, the screen frame 200 is fixed by clamping, which reduces the obstruction of the surface of the screen frame 200 away from the base 1, thereby avoiding interference when assembling the LCD screen 300, which is simple and easy to use.

[0064] In some embodiments, referring to Figures 1 to 6, the fixing mechanism 2 also includes a second operating member 23, which is connected to the first fixing member 21 and / or the second fixing member 22. Operating the second operating member 23 can drive the first fixing member 21 and / or the second fixing member 22 to move closer to or away from the mounting portion 11 along the first direction, so that the first fixing member 21 and the second fixing member 22 can move closer to or away from each other along the first direction.

[0065] Among them, the second operating member 23 can be connected to the first fixing member 21, and the second operating member 23 is operated to drive the first fixing member 21 to move along the first direction close to or away from the installation part 11, so that the first fixing member 21 moves close to or away from the second fixing member 22; the second operating member 23 can also be connected to the second fixing member 22, and the second operating member 23 is operated to drive the second fixing member 22 to move along the first direction close to or away from the installation part 11, so that the second fixing member 22 moves close to or away from the first fixing member 21; the second operating member 23 can also be connected to the first fixing member 21 and the second fixing member 22 at the same time, and the second operating member 23 is operated to drive the first fixing member 21 and the second fixing member 22 to move at the same time, and the movement directions of the first fixing member 21 and the second fixing member 22 are opposite through the transmission mechanism, so that the first fixing member 21 and the second fixing member 22 can move close to or away from the installation part 11 at the same time, so that the first fixing member 21 and the second fixing member 22 can move relatively close to or away from each other. In this way, the first fixing member 21 and the second fixing member 22 are manually driven by the second operating member 23 to move closer to or away from each other along the first direction, so that the first fixing member 21 and the second fixing member 22 abut against the side of the screen frame 200 or move away from the screen frame 200, thereby clamping, fixing or releasing the screen frame 200. The invention is simple and easy to use, has high reliability and low cost.

[0066] It should be noted that in an embodiment not shown in the figure, a power device such as a cylinder or a motor can also be used to automatically drive the first fixing member 21 and the second fixing member 22 to move toward or away from each other along the first direction to improve the degree of automation and save time and effort.

[0067] In some embodiments, the first fixing member 21 and / or the second fixing member 22 are made of elastic material. For example, the elastic material may be rubber, silicone, polyurethane, etc., which can elastically buffer the impact force and pressure between the first fixing member 21 and / or the second fixing member 22 and the screen frame 200, thereby reducing the force on the screen frame 200, making the screen frame 200 less susceptible to damage and improving the assembly quality.

[0068] In some embodiments, the first fixing member 21 is a fixed stopper, which is fixedly arranged on the base 1 and located on the side of the mounting portion 11 close to the hook assembly 31; the fixed stopper can be a metal block, such as iron, aluminum and its alloys, or a non-metal block, such as plastic, composite material, etc., which is not limited here. The second fixing member 22 is a movable stopper, which is movably arranged on the base 1 and located on the side of the mounting portion 11 away from the hook assembly 31; the movable stopper can be made of elastic material. The second operating member 23 is connected to the movable stopper, and the second operating member 23 can be operated to drive the movable stopper to move closer to or away from the mounting portion 11 along the first direction. When the screen frame 200 is placed on the mounting portion 11, one side of the screen frame 200 abuts against the fixed stopper, and the second operating member 23 is operated to drive the movable stopper to move toward the screen frame 200, so that the movable stopper abuts against the other side of the screen frame 200, so that the fixed stopper and the movable stopper cooperate to clamp the fixed screen frame 200.

[0069] In some embodiments, referring to Figures 2, 6, 8 and 9, the second operating member 23 is slidably disposed on the base 1, the sliding direction of the second operating member 23 is parallel to the first direction, and a limiting portion 231 is provided on the second operating member 23; the second operating member 23 can slide to a fixed position so that the first fixing member 21 and the second fixing member 22 can cooperate and abut against the opposite sides of the screen frame 200; the fixing mechanism 2 also includes a second locking member 24, and the second locking member 24 can cooperate and connect with the limiting portion 231 to lock the second operating member 23 in a fixed position.

[0070] The second operating member 23 can be a sliding handle. The second operating member 23 can slide along the first direction to a fixed position or a released position, so that the first fixing member 21 and the second fixing member 22 cooperate to clamp or release the screen frame 200. At the same time, a second locking member 24 is provided. When the second operating member 23 slides to the fixed position, the second locking member 24 cooperates with the limiting portion 231 of the second operating member 23 to prevent the second operating member 23 from moving toward the released position, thereby locking the second operating member 23 in the fixed position. In this way, the first fixing member 21 and the second fixing member 22 can be locked in a state of clamping and fixing the screen frame 200. The screen frame 200 is fixed stably and reliably, and is not easy to change position. After operating the second operating member 23 to fix the screen frame 200 on the mounting portion 11 of the base 1, you can let go without continuously operating the second operating member 23. It is convenient and labor-saving, simple and easy to use, and is conducive to improving assembly quality.

[0071] In some embodiments, referring to FIG. 6 and FIG. 9 , the fixing mechanism 2 further includes a mounting seat 25, which is fixedly arranged on the base 1, and a mounting through hole 251 is provided on the mounting seat 25 along the first direction; the second operating member 23 is slidably arranged in the mounting through hole 251, and the second operating member 23 can slide along the mounting through hole 251, and the mounting through hole 251 plays a guiding and limiting role in the sliding of the second operating member 23, so that the sliding of the second operating member 23 is more stable and not easy to deviate from the direction. The end of the second operating member 23 close to the mounting portion 11 is provided with a connecting frame 232, and the connecting frame 232 is connected to the second fixing member 22; the end of the second operating member 23 away from the mounting portion 11 is provided with an operating button 233, and the operating button 233 is pushed to drive the second operating member 23 to slide toward the mounting portion 11.

[0072] In some embodiments, referring to FIG. 2 , FIG. 6 , FIG. 8 and FIG. 9 , the fixing mechanism 2 further includes a third operating member 26 , and the third operating member 26 is operated to drive the second locking member 24 to separate from the limiting portion 231 .

[0073] For example, as shown in FIG6 and FIG9 , the second locking member 24 is movably provided on the mounting seat 25 along the third direction, one end of the second locking member 24 is provided in the mounting through hole 251, and the other end protrudes from the mounting seat 25; the limiting portion 231 of the second operating member 23 can be a limiting through hole, the second locking member 24 can move up and down along the third direction, and the end of the second locking member 24 is connected to or separated from the limiting through hole to lock or unlock the second operating member 23. One end of the third operating member 26 is rotatably connected to the base 1, and the other end is an operating end, and one end of the second locking member 24 protruding from the mounting seat 25 abuts between the operating end and the rotating connection end of the third operating member 26; the operating end is operated to rotate the third operating member 26 toward the direction close to the mounting seat 25, and the third operating member 26 can push the second locking member 24 to move along the second direction, thereby driving the second locking member 24 to separate from the limiting portion 231.

[0074] In this way, the second locking member 24 is manually driven by the third operating member 26 to separate from the limiting portion 231 of the second operating member 23, so that the lock of the second operating member 23 can be released, so that the second operating member 23 can slide to the release position, and drive the first fixing member 21 and / or the second fixing member 22 away from the screen frame 200, thereby releasing the screen frame 200, making it convenient to place the screen frame 200 into the installation portion 11 or take out the screen frame 200 module with the LCD screen 300 installed. The structure is simple, easy to use, stable and reliable.

[0075] The usage process of the assembly jig 100 of this embodiment is as follows: confirm that the first operating member 323 is in a state away from the mounting portion 11, and the flip member 313 is lifted upward, and the second fixing member 22 is in a released state away from the mounting portion 11; place the screen frame 200 on the assembly jig 100, push the second operating member 23 toward the mounting portion 11, drive the second fixing member 22 to press against the screen frame 200 toward one side of the mounting portion 11, and the first fixing member 21 to press against the screen frame 200 toward the other side of the mounting portion 11, so as to fix the screen frame 200; press the screen frame 200 downward with the flip member 313, and push the first operating member 323 in a direction away from the mounting portion 11, drive the hook 311 on the flip member 313 to hook the buckle 201 of the screen frame 200, and open the buckle 201 to the outside of the screen frame 200; at the same time, the magnetic suction member 33 uses magnetic attraction to absorb the flip member 313 to prevent the flip member 313 from tilting or the hook 311 from slipping. After completing the opening action of the buckle 201, put the LCD screen 300 into the screen frame 200, and then push the first operating member 323 toward the installation part 11, and then lift the flip member 313, and the buckle 201 of the screen frame 200 will retract to clamp the LCD screen 300; finally, lift the third operating member 26, push the second locking member 24 to separate from the limiting part 231, unlock the second operating member 23, and retract and reset in the direction away from the installation part 11. At this time, the screen frame 200 module with the LCD screen 300 installed can be taken out.

[0076] In some embodiments, the fixing mechanism 2 further includes a reset member (not shown in the figure), which is connected to the second operating member 23 and generates a force to move the second operating member 23 toward the release position. For example, the reset member may be a spring, which is connected between the second operating member 23 and the mounting seat 25. In this way, after the third operating member 26 is operated to release the lock on the second operating member 23, the second operating member 23 automatically returns to the release position under the action of the reset member, without manual operation, saving time and effort, and being simple and convenient to use.
