Description

Technical Field

[0001] The invention relates to the technical field of display screen installation, and in particular to a lock body mechanism of a display module. Background Art

[0002] LED display module is one of the main components of LED display finished products, mainly composed of LED lights, PCB circuit boards, driver ICs, resistors, capacitors and plastic kits.

[0003] The LED display screen used outdoors achieves the effect of large-screen display by installing multiple display modules on a rack one by one. The display screen used outdoors has extremely high requirements for heat dissipation due to direct sunlight. High temperature will cause damage to the display screen. In addition, since the display screen is outdoors, it needs to have a good waterproof sealing effect, but the waterproof sealing effect will affect the heat dissipation effect of the display module. How to reasonably lock the structure to meet the needs of the display module is an urgent problem to be solved. In addition, the current lock body structure cannot be opened and closed synchronously, and the operation is very cumbersome during installation. The installation of the high-altitude display screen is time-consuming and laborious. Based on this, a lock body mechanism for the display module is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, since the display screen is outdoors, it needs to have a good waterproof sealing effect, but the waterproof sealing effect will affect the heat dissipation effect of the display module. How to reasonably structure the lock body to meet the needs of the display module is a problem that urgently needs to be solved. A lock body mechanism of a display module is proposed. The lock body is locked by the main heat dissipation pipeline, and the heat dissipation template is directly locked by the dense heat dissipation pipe. While ensuring that the display template is firmly fixed, the effective heat dissipation of the display template can be achieved through the circulation of cooling water. In the process of installing and removing the display template, by changing the pressure in the main heat dissipation pipeline and the dense heat dissipation pipe, a plurality of display templates on the installation box are uniformly locked and unlocked, which can ensure that workers who install at high altitude can quickly and efficiently remove and install the display template. The pressure in the dense heat dissipation pipe is used to support the display template, and the pressure of the display template during outdoor use can be monitored at all times, so that the pressure information can be transmitted in time when the wind pressure is too large to ensure the safety of the large display screen.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A lock mechanism for a display module, comprising a display template connected to a display screen and a mounting box with a water cooling device installed, the mounting box is provided with a rectangular mounting track, a main heat dissipation pipeline is arranged in the rectangular mounting track, a mesh pad is arranged on the inner wall of the mounting box, a dense heat dissipation pipe is arranged on the mesh pad, one end of the dense heat dissipation pipe is connected to the main heat dissipation pipeline through a trigger seat, and the other end is connected to the main heat dissipation pipeline through a one-way valve, and the trigger seat is connected to the display template through a trigger member;

[0007] The inner wall of the rectangular mounting track is provided with a lock body for locking the display template. The lock body includes a pressure-bearing magnetic plate arranged on the rectangular mounting track. The side wall of the pressure-bearing magnetic plate is fixedly connected with a connecting lock body. The inner wall of the connecting lock body is provided with a heat dissipation rubber pad.

[0008] Preferably, a connecting cavity is provided inside the trigger seat, and openings are provided at both ends of the connecting cavity. A limiting sealing ring is provided in the opening, and the end of the limiting sealing ring is connected to a resisting magnetic ball that penetrates into the connecting cavity, and the two resisting magnetic balls arranged opposite to each other are magnetically attracted to each other.

[0009] Preferably, the trigger member includes a connecting seat installed on the display template, the connecting seat is connected to a trigger ball through a resistance column, the connecting seat is connected to a sealed outer cover body through a resistance spring sleeved on the outer side wall of the resistance column, and a sealed inner cover body is provided on the side wall of the trigger seat located at the connecting cavity.

[0010] Preferably, the rectangular mounting rail is made of metal and has an adsorption effect with the pressurized magnetic plate, and the main heat dissipation pipe and the dense heat dissipation pipe are both flexible pipes.

[0011] Preferably, the heat dissipation rubber pad is arc-shaped, and has a gap when not under pressure, which can meet the effect of heat dissipation when wind enters, and deforms under pressure to achieve a sealing effect.

[0012] Preferably, a pressure control valve and a pressure sensor connected to a water cooling device are provided on one side of the installation box, and the pressure control valve is communicated with a main heat dissipation pipeline.

[0013] Preferably, the connecting lock body and the side walls opposite to the display template are both arranged in an arc shape, so as to facilitate the installation of the display template.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention performs abutment locking on the lock body through the main heat dissipation pipeline, and directly performs abutment locking on the heat dissipation template through the dense heat dissipation pipe. While ensuring that the display template is firmly fixed, the display template can be effectively dissipated through the circulation of cooling water.

[0016] 2.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example, see Figure 1-Figure 8 , a lock mechanism of a display module, comprising a display template 2 connected to a display screen 1 and a mounting box 3 with a water cooling device installed, the water cooling device is a prior art and will not be described in detail here;

[0030] Furthermore, a pressure control valve and a pressure sensor connected to the water cooling device are provided on one side of the installation box 3 , and the pressure control valve is communicated with the main heat dissipation pipeline 5 .

[0031] It is worth noting that the pressure sensor can detect the wind pressure that the large display screen composed of the entire display module is subjected to, so as to transmit the pressure information in time when the wind pressure is too high to ensure the safety of the large display screen.

[0032] The pressure control valve is connected to the main heat dissipation pipe 5, and can actively control the pressure in the main heat dissipation pipe 5, thereby controlling the cooling water pressure in the main heat dissipation pipe 5 and the dense heat dissipation pipe 7, and regulating the lock body.

[0033] A rectangular mounting track 4 is provided on the mounting box 3, a main heat dissipation pipe 5 is provided in the rectangular mounting track 4, a mesh pad 6 is provided on the inner wall of the mounting box 3, a dense heat dissipation pipe 7 is provided on the mesh pad 6, one end of the dense heat dissipation pipe 7 is connected to the main heat dissipation pipe 5 through a trigger seat 8, and the other end is connected to the main heat dissipation pipe 5 through a one-way valve 9, and the trigger seat 8 is connected to the display template 2 through a trigger member;

[0034] Furthermore, a connecting cavity is opened inside the trigger seat 8, and openings 13 are opened at both ends of the connecting cavity. A limit sealing ring 14 is arranged in the opening 13, and the end of the limit sealing ring 14 is connected to a resisting magnetic ball 15 that penetrates into the connecting cavity. The two resisting magnetic balls 15 arranged opposite to each other are magnetically attracted to each other.

[0035] It is worth noting that the resisting magnetic ball 15 is in an attractive state when not squeezed by the trigger ball 18. In this state, setting the limiting sealing ring 14 can achieve the effect of sealing the opening 13 and preventing the cooling water in the main heat dissipation pipe 5 from entering the dense heat dissipation pipe 7.

[0036] Furthermore, the trigger member includes a connecting seat 16 installed on the display template 2, the connecting seat 16 is connected to a trigger ball 18 through a resistance column 17, the connecting seat 16 is connected to a sealed outer cover body 19 through a resistance spring sleeved on the outer side wall of the resistance column 17, and a sealed inner cover body 20 is provided on the side wall of the trigger seat 8 located at the connecting cavity.

[0037] It is worth noting that the contact surfaces of the sealed outer cover 19 and the sealed inner cover 20 are both provided with sealing rubber to ensure the sealing effect during contact and avoid leakage.

[0038] A further advantage of adopting the above method is that when the display template 2 is installed, the trigger ball 18 disposed on the connecting seat 16 thereof will be driven to be inserted between the two abutting magnetic balls 15 in the connecting cavity, thereby achieving conduction of the trigger seat 8.

[0039] The inner wall of the rectangular mounting track 4 is provided with a lock body for locking the display template 2. The lock body includes a pressure-bearing magnetic plate 10 arranged on the rectangular mounting track 4. The rectangular mounting track 4 is made of metal and has an adsorption effect with the pressure-bearing magnetic plate 10. The pressure-bearing magnetic plate 10 has a magnetic effect that when the internal pressure of the main heat dissipation pipe 5 is reduced and retracted, it will not drive the pressure-bearing magnetic plate 10 to retract, thereby relieving the resistance to the lock body, but will not affect the temporary support for the display template 2. The main heat dissipation pipe 5 and the dense heat dissipation pipe 7 are both flexible pipes.

[0040] A connecting lock body 11 is fixedly connected to the side wall of the pressure-bearing magnetic plate 10 . The connecting lock body 11 and the side wall opposite to the display template 2 are both arranged in an arc shape, which is convenient for installing the display template 2 .

[0041] A heat dissipation rubber pad 12 is arranged on the inner wall of the connecting lock body 11. The heat dissipation rubber pad 12 is arranged in an arc shape. There is a gap when there is no pressure, which can meet the effect of heat dissipation caused by wind entering. It deforms under pressure to achieve a sealing effect.

[0042] During installation, the present invention can inject a coolant of a certain pressure into the main heat dissipation pipe 5, so that the coolant expands the main heat dissipation pipe 5 to a standard, exerts a certain extrusion force on the lock body, and at this time, the display template 2 is installed, the display template 2 will contact the connecting lock body 11, and drive the connecting lock body 11 to move into the rectangular installation track 4, and the display template 2 will move to the position between the dense heat dissipation pipe 7 and the connecting lock body 11;

[0043] At this time, when the display template 2 is installed, the trigger ball 18 on the connecting seat 16 will be driven to be inserted between the two abutting magnetic balls 15 in the connecting cavity. Under this action, the trigger seat 8 will be turned on, and the dense heat dissipation pipe 7 will be connected with the main heat dissipation pipe 5. The cooling water will enter the dense heat dissipation pipe 7, so that the dense heat dissipation pipe 7 will expand. Under the action of expansion, the display template 2 will be pushed outward to make it contact with the heat dissipation rubber pad 12 on the back of the connecting lock body 11, so as to realize the rapid installation of the display template 2. At this time, the heat dissipation rubber pad 12 is not deformed, and a gap is set therein, which can meet the heat dissipation and ventilation requirements of the display template 2.

[0044] Before it rains, the pressure of the dense heat dissipation tube 7 and the main heat dissipation pipeline 5 can be increased by controlling the pressure control valve. Under the action of the pressure, the dense heat dissipation tube 7 will expand and apply greater pressure to the display template 2. Under the action of the pressure, the heat dissipation rubber pad 12 will be deformed. The deformed heat dissipation rubber pad 12 will fill the gap between the display template 2 and the connecting lock body 11, preventing rainwater from entering the installation box 3, and significantly improving the waterproof effect of the equipment;

[0045] When the large display screen needs to be disassembled, the cooling water in the dense heat dissipation pipe 7 and the main heat dissipation pipe 5 can be discharged by controlling the pressure control valve. The dense heat dissipation pipe 7 without pressure will release the interference lock on the display template 2, and the main heat dissipation pipe 5 will also release the interference lock on the lock body;

[0046] At this time, when dismantling, the worker only needs to move the connecting lock bodies 11 arranged around the installation box 3 inward, take out the display template 2, and release the locks uniformly, so that the display template 2 can be dismantled quickly and efficiently.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
