Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen fixing frames, in particular to an LED display screen fixing component. Background Art

[0002] LED electronic display is a display method that controls semiconductor light emitting diodes. It is composed of tens of thousands to hundreds of thousands of semiconductor light emitting diode pixels arranged evenly. It uses different materials to produce LED pixels of different colors to display text, graphics, images, animations, quotes, videos, video signals and other information.

[0003] LED electronic display screens are usually used as computer screens or TV screens. When LED electronic display screens are used and assembled, they usually need to be fixed to the outside of the wall using a fixing device. During assembly, the existing display screen brackets need to be repeatedly adjusted in position with a level, and holes need to be punched after marking the fixed position with a pen. Too many operating steps will result in a long time required to assemble the bracket, thereby reducing the installation speed of the display screen. Utility Model Content

[0009] Preferably, the outer top of the transverse tube is connected to a first one-way valve, and the first one-way valve can provide one-way air supply to the interior of the transverse tube.

[0010] Preferably, a sealing gasket is embedded in the front of the hollow sleeve, and the sealing gasket is an arc-shaped rubber gasket, which increases the stability of the assembly frame when the bolts and nuts are fixed.

[0011] Preferably, a rubber baffle is embedded on the back of the hollow sleeve, and a spray hole is connected to the back of the hollow sleeve, through which the ink can be discharged, and the rubber baffle can intercept the ink so that the ink coats a limited area of ​​the hollow sleeve.

[0012] Preferably, the bottom of the hollow sleeve is connected to a second one-way valve, the second one-way valve is connected to the curved pipe, and the second one-way valve enables the hollow sleeve to discharge ink in only one direction.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 , an LED display screen fixing component, comprising: an assembly frame 1, a scissor mechanism 2, a card board 3 and a limit frame 4. This scheme is a structural improvement of the non-electronic component part based on the display screen fixing bracket of the prior art, wherein the assembly frame 1, the scissor mechanism 2, the card board 3 and the limit frame 4 are common display screen fixing bracket products that have been promoted in the prior art. The assembly frame 1 can be fixed on the wall, the scissor mechanism 2 can change the position of the card board 3, the card board 3 is connected to the scissor mechanism 2 by clamping or bolting, the limit frame 4 can be fixed on the back of the display screen, the scissor mechanism 2 is assembled on the front of the assembly frame 1, the card board 3 is assembled on the front of the scissor mechanism 2, the limit frame 4 is assembled on both ends of the card board 3, the front of the assembly frame 1 is connected with a level 5, and both ends of the front of the assembly frame 1 are connected with a marking mechanism 6.

[0023] See also Figure 3 , Figure 4 and Figure 5 The marking mechanism 6 includes a transverse tube 61, the interior of which can store ink, and the transverse tube 61 is connected to the assembly frame 1. The interior of the transverse tube 61 is slidably connected with a piston 62, which can squeeze and discharge the ink. The outside of the piston 62 is connected with a push rod 63 through a seat bearing, and the push rod 63 can push the piston 62 to move. Both ends of the transverse tube 61 are connected with a bent pipe 66, which can discharge the ink into the interior of the hollow sleeve 68, and the other end of the bent pipe 66 is connected with the hollow sleeve 68.

[0024] The outside of the piston 62 is connected to a spring 64, which is connected to the inside of the cross tube 61. The spring 64 can drive the piston 62 to return after movement. The top of the outside of the cross tube 61 is connected to a first one-way valve 65, which can provide one-way air supply to the inside of the cross tube 61. A sealing gasket 681 is embedded in the front of the hollow sleeve 68. The sealing gasket 681 is an arc-shaped rubber gasket. The sealing gasket 681 increases the stability of the assembly frame 1 when the bolts and nuts are fixed.

[0025] A rubber baffle 683 is embedded on the back of the hollow sleeve 68. The back of the hollow sleeve 68 is connected to a nozzle 682, which can discharge ink. The rubber baffle 683 can intercept the ink so that the ink coats a limited area of ​​the hollow sleeve 68. The bottom of the hollow sleeve 68 is connected to a second one-way valve 67, which is connected to the curved pipe 66. The second one-way valve 67 allows the hollow sleeve 68 to discharge ink in only one direction.

[0026] The interior of the transverse tube 61 is connected with a slotted ring 7, and the exterior of the push rod 63 is sleeved with a clamping block 71, which is matched with the slotted ring 7. The clamping block 71 can be rotated to the interior of the slotted ring 7 to fix the position of the push rod 63.

[0027] In this solution, the card plate 3 and the scissor mechanism 2 are first separated, the limit frame 4 is fixed to the back of the display screen by bolts, the assembly frame 1 is fitted to the position to be fixed, the push rod 63 is rotated 180° to release the push rod 63 from the fixation of the slotted ring 7, and the horizontal position of the assembly frame 1 is observed by the level 5. After the position is adjusted, the two push rods 63 are squeezed in relative directions to make the piston 62 move inside the cross tube 61 to generate pressure, and the ink inside the cross tube 61 is discharged into the hollow sleeve 68 through the bend 66, and the ink is sprayed out through the nozzle 682 and blocked by the rubber baffle 683, and the wall with an area of ​​the hollow sleeve 68 is coated, and bolts are driven into the wall through the coated area, and then the hollow sleeve 68 and the bolts are fixed by nuts, and the card plate 3 is connected to the scissor mechanism 2 to complete the fixation of the LED display screen.

[0028] When the LED display screen is being fixed, the additional marking mechanism 6 can cooperate with the level meter 5 to quickly determine the required fixing position of the assembly frame 1, avoiding the traditional method of repeatedly comparing the fixing position and then marking with a pen, thereby delaying the assembly of the LED display screen, and avoiding the lack of necessary positioning tools during the assembly of the LED display screen, which may cause the position of the LED display screen to be skewed after the assembly is completed. At the same time, when the push rod 63 is not in use, it is fixed by the additional slotted ring 7 and the block 71, avoiding the push rod 63 being accidentally touched when the assembly frame 1 does not need to be fixed in position, thereby causing the ink inside the cross tube 61 to be sprayed out.
