Description

Technical Field

[0001] The utility model belongs to the technical field related to the sucker structure, and particularly relates to a sucker structure for an LED display screen. Background Technique

[0002] An LED display screen is a flat panel display with light-emitting diodes (LEDs) as the basic display units. The LED display screen has many advantages. First of all, it has excellent color expressiveness and can present vivid, clear and realistic images and videos. For example, on large outdoor advertising screens, vivid colors can quickly attract people's attention.

[0003] For example, the Chinese patent with the publication number CN216044944U discloses a front maintenance sucker structure for an LED display screen, which relates to the technical field of sucker structures, including a disk bottom. A support block is fixedly arranged on the upper surface of the center of the disk bottom. A groove is arranged on the upper surface of the support block. A handle is inserted into the inner wall of the groove. One end of the top of the handle is inserted with a pressing rod. A clamping plate is arranged on the upper surface of the disk bottom inside the support block. A clamping groove is arranged at the bottom end of one end of the handle. The clamping groove is adapted to the clamping plate. One end of the pressing rod penetrates through the top of the handle and extends towards the bottom end of the handle. A limiting block is fixedly arranged on the upper surface of one end of the pressing rod inside the handle. A limiting spring is fixedly arranged on the top of the limiting block. By arranging a groove on the upper surface of the support block and then making the handle telescopically arranged in the groove, the traditional fixed connection mode between the handle and the disk body is changed, so that the handle does not occupy a large space, thereby reducing the packaging cost required for the production of the sucker structure.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages during use. For example, during the use of this device, the handle is fixed to the disk bottom through a compression spring. The compression spring has a certain elasticity, which will cause the handle to be unstable during use. Moreover, the part of the handle for holding is rectangular, which will cause the comfort of the staff holding it by hand to be relatively low. In view of this, we propose a sucker structure for an LED display screen. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sucker structure for an LED display screen to solve the problems put forward in the above background technique.

[0007] In view of this, the utility model provides a sucker structure for an LED display screen, including a disk bottom, and further including:

[0008] An installation block is fixedly installed on the top of the bottom of the disc. A U-shaped groove is formed in the installation block. Activity grooves are symmetrically formed in the installation block. The activity grooves communicate with the U-shaped groove. Two power chambers are formed in the installation block and located between the two activity grooves. Chute grooves are formed on both sides of the power chamber. The chute grooves communicate with the corresponding activity grooves;

[0009] Two activity posts are respectively and movably installed in the two activity grooves. Rectangular grooves are formed at the opposite ends of the two activity posts. A threaded rod is rotatably installed in the chute groove. A rectangular rod is slidably installed on the threaded rod in the chute groove. One end of the two rectangular rods away from each other respectively extends into the two rectangular grooves. One end of the two activity posts away from each other and located in the U-shaped groove is fixedly installed with the same U-shaped handle. And a rubber ring is fixedly installed on the U-shaped handle;

[0010] A driving assembly is located in the installation block and is used to drive the four threaded rods to rotate.

[0011] In this technical solution, when the U-shaped handle is retracted, through the arranged driving assembly, the driving assembly drives the four threaded rods to rotate. Subsequently, under the action of the thread, two of the threaded rods will drive two of the rectangular rods to approach each other, and the other two threaded rods will drive the other two rectangular rods to approach each other. Subsequently, one end of the two rectangular rods away from each other will be withdrawn from the corresponding rectangular groove. When the rectangular rod completely enters the corresponding chute groove, at this time, the two activity posts will be released from the limit. Subsequently, the staff can rotate the U-shaped handle downward, so that the U-shaped handle drives the two activity posts to rotate in the corresponding activity grooves. After the U-shaped handle rotates downward by 90°, the U-shaped handle will be located in the U-shaped groove. Subsequently, push the U-shaped handle, so that the two activity posts slide in the corresponding activity grooves and displace toward the direction of the handle until the two activity posts can no longer continue to displace. Subsequently, through the arranged driving assembly, the driving assembly drives the four threaded rods to rotate again. Subsequently, two of the threaded rods will drive two of the rectangular rods to move away from each other, and the other two threaded rods will drive the other two rectangular rods to move away from each other until one end of the other two rectangular rods away from each other is inserted into the corresponding rectangular groove to fix the two activity posts, so that the activity posts will not rotate. At the same time, the U-shaped handle will also be fixed in the U-shaped groove.

[0012] In the above technical solution, further, the driving assembly includes:

[0013] Two worm wheels, the two worm wheels are respectively rotatably installed in two power chambers, both ends of the worm wheel respectively penetrate through both sides of the power chamber and extend into the corresponding sliding grooves, and both ends of the worm wheel are coaxially connected to the corresponding threaded rods respectively. A worm is rotatably installed at the top of the worm wheel in the power chamber, and the two worms are coaxially connected. One side of the installation block is rotatably installed with a handle, and one end of the handle penetrates through one side of the installation block and extends into one of the sliding grooves and is coaxially connected to one of the worms.

[0014] In this technical solution, the staff rotates the handle forward, so that the handle drives one of the worms to rotate. Subsequently, one of the worms will drive the other worm to rotate. Under the meshing action, the two worms will drive the corresponding worm wheels to rotate. Subsequently, the worm wheels will drive the corresponding threaded rods to rotate. At this time, under the action of the thread, two of the threaded rods will drive two of the rectangular rods to approach each other, and the other two threaded rods will drive the other two rectangular rods to approach each other.

[0015] In the above technical solution, further, both ends of the worm wheel are rotatably connected to the corresponding sliding grooves, the worm wheel meshes with the worm, the worm is rotatably connected to the installation block, and one end of the handle is rotatably connected to one of the sliding grooves.

[0016] In this technical solution, ensure that the worm wheel can operate normally; under the meshing action, ensure that the worm can drive the worm wheel to rotate when it rotates; ensure that the worm can rotate normally; ensure that the handle can rotate normally.

[0017] In the above technical solution, further, the rectangular rod is threadedly connected to the threaded rod.

[0018] In this technical solution, under the action of the thread, ensure that the threaded rod can drive the rectangular rod to displace when it rotates.

[0019] In the above technical solution, further, one end of the rectangular rod is inserted and matched with the rectangular groove, and the other ends of the other two rectangular rods respectively extend into the two movable grooves, and one end of the rectangular rod is slidably connected to the movable groove.

[0020] In this technical solution, ensure that one end of the rectangular rod can be inserted into the rectangular groove; ensure that the rectangular rod can enter the movable groove.

[0021] In the above technical solution, further, the U-shaped handle and the movable column are of an integrally formed structure, and the U-shaped handle is movably connected to the U-shaped groove.

[0022] In this technical solution, ensure the structural stability between the U-shaped handle and the movable column; ensure that the U-shaped handle can move in the U-shaped groove.

[0023] The beneficial effects of the present utility model are:

[0024] The sucker structure for the LED display screen, through the cooperation among the provided mounting block, U-shaped groove, movable groove, rectangular rod, movable column, threaded rod, chute, rectangular groove and driving component, ensures that when the U-shaped handle is opened, the U-shaped handle is more stable with the mounting block, and the U-shaped handle will not shake.
