[0002] A COB (Chip-on-Board) display screen is a display technology that integrates LED chips and control circuits. In a COB display screen, LED chips are directly encapsulated on a PCB (Printed Circuit Board) to form a highly integrated display module, which can achieve high integration and high brightness. The overall structure of the COB display screen is simple, reducing the connections between components and improving reliability and seismic resistance.

[0003] Currently, during the use of existing COB display screens, power connection wires, signal connection wires, etc. usually need to be plugged into the wiring holes behind the COB display screen, resulting in the connection wires being tangled and chaotic, interfering with each other and affecting normal use. It will also cause the plug of the connection wire to become loose. Moreover, when the plug of the connection wire is pulled out and not used for a long time, dust will accumulate in the jack, affecting the connection effect when the connection wire is plugged in and affecting normal use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that the connection wires interfere with each other, easily cause the plugs of the connection wires to become loose, and the jacks are prone to dust ingress, and to propose a COB display screen with anti-interference ability.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A COB display screen with anti-interference ability includes a display screen housing. A COB display screen body is arranged inside the display screen housing. It also includes at least one set of mounting seats, which are slidably arranged on the back of the display screen housing. Card wire grooves for fixing connection wires are formed on the mounting seats. An interface is formed on the back of the display screen housing. One end of the mounting seat abuts against the end face of the opening of the interface.

[0007] In order to ensure the reliable sliding of the mounting seat, preferably, a guiding groove is formed on the back of the display screen housing. A guiding block is fixedly arranged at the bottom of the mounting seat. The guiding block is slidably arranged in the guiding groove, and an elastic member is arranged in the guiding groove.

[0008] In order to facilitate the reset of the mounting seat, further, the elastic member includes a first spring. Two ends of the first spring are respectively fixedly connected with the guiding groove and the guiding block.

[0009] In order to improve the sliding and anti - detachment of the guiding block, further, the guiding block has a T - shaped structure, and a fillet is fixedly arranged on the guiding block.

[0010] Preferably, a limiting groove is opened at one end of the mounting seat close to the interface. A baffle for blocking the wire clamping groove is slidably arranged in the limiting groove. The outer wall of the baffle abuts against the end face of the mouth of the interface. And a second spring is arranged in the limiting groove, and both ends of the second spring are fixedly connected to the baffle and the limiting groove respectively.

[0011] Preferably, the wire clamping groove penetrates through the wall thickness of the mounting seat, and the wire clamping groove includes an arc - shaped groove and a through - groove communicating with the arc - shaped groove.

[0012] Further, the distance between the inner walls on both sides of the through - groove is smaller than the diameter of the connecting wire, and the diameter of the arc - shaped groove is larger than the diameter of the connecting wire.

[0013] Preferably, it further includes a base. Among them, a column is fixedly arranged on the base. A swivel joint is rotatably arranged at one end of the column away from the base. A plug - in groove is opened on the back of the display screen housing. The swivel joint is fixedly arranged in the plug - in groove through a bolt. And a limiting column for restricting the rotation of the swivel joint is arranged on the column.

[0014] Compared with the prior art, the utility model provides a COB display screen with anti - interference ability, and has the following beneficial effects:

[0015] 1. For the COB display screen with anti - interference ability, by slidably arranging the mounting seat on the display screen housing and opening the wire clamping groove on the mounting seat, on the one hand, the connecting wires are clamped in the wire clamping groove, which can reduce the phenomenon of winding and mutual interference of the connecting wires. On the other hand, the mounting seat abuts against the end of the plug away from the interface. Under the elastic force of the first spring, the mounting seat has a tendency to push the plug into the interface, which can avoid the loosening of the connection of the connecting wire plug and improve the connection effect. When the mounting seat abuts against the end face of the mouth of the interface, it can reduce the entry of dust into the interface and ensure the connection quality of the interface.

[0016] 2. For the COB display screen with anti - interference ability, by slidably arranging a baffle on the mounting seat, on the one hand, it can reduce the interference with the connecting wires and ensure that the connecting wires are reliably located in the wire clamping groove. On the other hand, it can block the wire clamping groove. Together with the mounting seat, it can completely block the mouth of the interface and improve the dust - proof effect.

[0017] For the parts not involved in this device, they are the same as the prior art or can be implemented using the prior art. In this utility model, an installation base is slidably arranged on the display screen housing, and a wire clamping groove is formed on the installation base, where the connecting wire can be clamped in the wire clamping groove to reduce the phenomenon of the connecting wires being entangled and interfering with each other. At this time, the installation base abuts against the end of the plug away from the interface. Under the elastic force of the first spring, the phenomenon of the connecting wire plug being loose in insertion can be avoided. At the same time, when the installation base abuts against the end face of the mouth of the interface, the entry of dust into the interface can be reduced, ensuring the connection quality of the interface.

[0025] Example:

[0026] Referring to Figures 1 - 4 , a COB display screen with anti-interference ability, including a display screen housing 1, a COB display screen body is fixedly arranged in the display screen housing 1, and further includes at least one set of mounting seats 2, which are slidably arranged on the back of the display screen housing 1. A card wire groove 202 for fixing the connecting wire is opened on the mounting seat 2. An interface 101 is opened on the back of the display screen housing 1. Two to five groups of interfaces 101 are opened, preferably three groups. Here, we also preferably select three groups of mounting seats 2, and they correspond to the interfaces 101 one by one. One end of the mounting seat 2 abuts against the mouth end face of the interface 101. When in use, when no connecting wire plug is inserted at the interface 101, one end face of the mounting seat 2 abuts against the mouth end face of the interface 101, which can reduce dust from entering the interface 101 and ensure the connection quality of the interface 101; when it is necessary to insert the connecting wire plug into the interface 101, first push the mounting seat 2 away from the interface 101, then insert the connecting wire plug into the interface 101. After the insertion is completed, then press the connecting wire into the card wire groove 202, and finally release the push on the mounting seat 2. At this time, the mounting seat 2 will abut against the connecting wire plug. On the one hand, the connecting wire can be stuck in the card wire groove 202, which can reduce the phenomenon of the connecting wires being entangled and interfering with each other. On the other hand, the mounting seat 2 abuts against the end of the plug away from the interface 101. Under the elastic force of the first spring 104, the mounting seat 2 has a tendency to push the plug into the interface 101, which can avoid the phenomenon of the connecting wire plug being loosely inserted and improve the connection effect.

[0027] When in use, by slidably arranging the mounting seat 2 on the display screen housing 1 and opening a card wire groove 202 on the mounting seat 2, on the one hand, the connecting wire can be stuck in the card wire groove 202, which can reduce the phenomenon of the connecting wires being entangled and interfering with each other. On the other hand, the mounting seat 2 abuts against the end of the plug away from the interface 101. Under the elastic force of the first spring 104, the mounting seat 2 has a tendency to push the plug into the interface 101, which can avoid the phenomenon of the connecting wire plug being loosely inserted and improve the connection effect. When the mounting seat 2 abuts against the mouth end face of the interface 101, it can reduce dust from entering the interface 101 and ensure the connection quality of the interface 101; by slidably arranging a baffle 3 on the mounting seat 2, on the one hand, it can reduce the interference with the connecting wire and ensure that the connecting wire is reliably located in the card wire groove 202. On the other hand, it can block the card wire groove 202. Together with the mounting seat 2, it can completely block the mouth of the interface 101 and improve the dust-proof effect.

[0028] Referring to Figure 1, a guiding groove 102 is formed on the back of the display screen housing 1. There are two to five groups of guiding grooves 102, preferably three groups. A guiding block 201 is fixedly arranged at the bottom of the mounting seat 2. The guiding block 201 is slidably arranged in the guiding groove 102, and an elastic member is arranged in the guiding groove 102. During use, by forming the guiding groove 102 on the back of the display screen housing 1 and fixedly arranging the guiding block 201 at the bottom of the mounting seat 2, the reliable sliding of the mounting seat 2 can be ensured. Then, under the elastic force of the elastic member, the mounting seat 2 can be made to abut against the end face of the connecting line plug away from the interface 101 to prevent the plug connection from loosening, or the mounting seat 2 can abut against the mouth end face of the interface 101 to reduce the entry of dust into the interface 101 and improve the use effect.

[0029] Refer to Figure 1 , the elastic member can be a spring piece, an elastic capsule, elastic rubber, etc. Here, we preferably use the first spring 104 as the elastic member. The two ends of the first spring 104 are respectively fixedly connected to the guiding groove 102 and the guiding block 201. During use, under the elastic force of the first spring 104, the mounting seat 2 can reliably abut against the end face of the plug away from the interface 101 or the mouth end face of the interface 101.

[0030] Refer to Figure 3 and Figure 4 , here, the guiding block 201 has a T-shaped structure, and a fillet is fixedly arranged on the guiding block 201. During use, by designing the guiding block 201 as a T-shaped structure, on the one hand, the connection effect with the guiding groove 102 is improved, having a guiding and anti-detachment effect; on the other hand, by arranging a fillet on the guiding block 201, it is convenient for the guiding block 201 to slide in the guiding groove 102.

[0031] Refer to Figure 4 , a limiting groove 203 is formed at one end of the mounting seat 2 close to the interface 101. A baffle 3 for blocking the card wire groove 202 is slidably arranged in the limiting groove 203, and the outer wall of the baffle 3 abuts against the mouth end face of the interface 101. A second spring is arranged in the limiting groove 203, and the two ends of the second spring are respectively fixedly connected to the baffle 3 and the limiting groove 203. During use, by slidably arranging the baffle 3 on the mounting seat 2, when a plug is inserted at the interface 101, the baffle 3 slides into the limiting groove 203 to avoid blocking the card wire groove 202, facilitating the card wire groove 202 to clamp the connecting wire. When no plug is inserted at the interface 101, the baffle 3 slides upward to block the card wire groove 202, and together with the mounting seat 2, it can block the mouth of the interface 101, further reducing the entry of dust into the interface 101.

[0032] Refer to Figure 3 and Figure 4, the wire clamping groove 202 penetrates through the wall thickness of the mounting base 2. The axis of the wire clamping groove 202 is parallel to the insertion direction of the interface 101. Moreover, the wire clamping groove 202 includes an arc-shaped groove and a through groove communicating with the arc-shaped groove. And the distance between the inner walls on both sides of the through groove is less than the diameter of the connecting wire, and the diameter of the arc-shaped groove is greater than the diameter of the connecting wire. During use, since the wire clamping groove 202 is composed of an arc-shaped groove and a through groove, and the inner wall spacing of the through groove is less than the diameter of the connecting wire, during the use process, the connecting wire can be pressed into the through groove and then enter the arc-shaped groove to realize the restriction of the connecting wire, which can reduce the phenomenon of mutual entanglement and interference between the connecting wires, and can also prevent the connecting wire from falling off from the wire clamping groove 202, affecting the use effect.

[0033] Refer to Figure 1 and Figure 2 , a COB display screen with anti-interference ability further includes a base 4. Among them, a column 401 is fixedly arranged on the base 4. A swivel joint 402 is rotatably arranged at one end of the column 401 away from the base 4. A plug-in groove 103 is opened on the back of the display screen housing 1. The swivel joint 402 is fixedly arranged in the plug-in groove 103 by bolts. And a limit post 403 for restricting the rotation of the swivel joint 402 is arranged on the column 401. The rotation mode of the swivel joint 402 is the prior art and will not be introduced in detail here. During use, the end of the swivel joint 402 away from the column 401 is inserted into the plug-in groove 103, and then the swivel joint 402 is fixed in the plug-in groove 103 by bolts. Then, the angle between the swivel joint 402 and the column 401 is adjusted, and the pitching angle of the display screen housing 1 can be adjusted to improve the use effect.
