[0030] The present application is described in detail below. Examples of embodiments of the present application are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. In addition, if the detailed description of the known technology is not necessary for the features of the present application shown, it will be omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0031] Those skilled in the art will understand that, unless otherwise stated, the singular forms "a," "an," "said," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of this application refers to the presence of the stated features, elements, and / or components, but does not preclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0032] The present application provides a connector for use in an LED display screen assembly. The connector primarily comprises a rod core 1, a rod sleeve 2, a locking rod 3, and a clamping structure 4. The rod sleeve 2 is partially sleeved on the outside of the rod core 1, and the rod sleeve 2 can be moved axially toward or away from the rod core 1 to adjust the length of the rod core 1 extending out of the rod sleeve 2. The locking rod 3 is connected to the end of the rod sleeve 2 that is away from the rod core 1. A limiting protrusion protruding from the sidewall is formed on the end of the locking rod 3 that is away from the rod sleeve 2. The limiting protrusion is used to lock the connection with the LED display screen 7. The clamping structure 4 is connected to the end of the rod core 1 that is away from the rod sleeve 2. The clamping structure 4 is used to connect to the bracket 6.

[0033] like Figure 1-2 As shown, the connecting piece provided in the embodiment of the present application is locked and connected to the LED display screen 7 through a limiting protrusion, and is connected to the bracket 6 through a clamping structure 4. The relative positions of the rod core 1 and the rod sleeve 2 are adjusted, and the distance between the limiting protrusion and the clamping structure 4 is adjusted to connect the LED display screen 7 and the bracket 6. The structure of the connecting piece is simple and the operation is convenient. The distance between the limiting protrusion and the clamping structure 4 is further reduced to achieve a close connection between the three and improve the stability of the connection.

[0034] As an optional embodiment, the rod sleeve 2 has a hollow structure, and the rod sleeve 2 is sleeved on the outside of the rod core 1 through the hollow structure; the side wall of the rod core 1 is provided with a limiting groove 11 extending along the axial direction, and the limiting groove 11 is recessed radially inward; the sleeve wall of the rod sleeve 2 is provided with a threaded through hole 21, which is connected to the hollow structure, and the bolt passes through the threaded through hole 21 and extends into the limiting groove 11 to limit the relative position of the rod sleeve 2 and the rod core 1.

[0035] Based on the previous embodiment, in this embodiment, the rod core 1 is moved axially away from or toward the rod sleeve 2. When the rod core 1 moves to the point where the bolt contacts the end of the limiting groove 11, the rod core 1 reaches its maximum movement distance in the corresponding direction. After the relative position of the rod core 1 and the rod sleeve 2 is adjusted, the screw is screwed so that the end of the screw extending into the limiting groove 11 abuts against the limiting groove 11, thereby fixing the relative position of the rod core 1 and the rod sleeve 2.

[0036] As an optional embodiment, a fixing through hole is opened at one end of the locking rod 3 away from the rod sleeve 2, and a limiting column 5 is fixed in the fixing through hole. The axial direction of the limiting column 5 is perpendicular to the axial direction of the locking rod 3, and both ends of the limiting column 5 protrude from the locking rod 3.

[0037] Based on the above embodiments, in this embodiment, the axial direction of the fixing through hole is arranged along the radial direction of the locking rod 3. The vertical limiting column 5 and the locking rod 3 form a stable connection structure to ensure structural strength.

[0038] As an optional embodiment, the clamping structure 4 includes a first curved wall 41, a threaded rod 42, a second curved wall 43, and a nut structure 44. The first curved wall 41 is connected to the rod core 1; the threaded rod 42 is rotatably connected to one end of the first curved wall 41; the first end of the second curved wall 43 is rotatably connected to the other end of the first curved wall 41; the second end of the second curved wall 43 is used to lock the threaded rod 42; the first curved wall 41, the second curved wall 43, and the threaded rod 42 form a clamping ring; the nut structure 44 is sleeved on the outside of the threaded rod 42 to tighten the clamping ring.

[0039] Based on the previous embodiment, in this embodiment, the middle portion of the convex side of the first curved wall 41 has a threaded section, which is used to thread the first curved wall 41 into the rod core 1. The recessed portions of the first curved wall 41 and the second curved wall 43 correspond to each other. The first curved wall 41, the second curved wall 43, and the threaded rod 42 form a clamping ring, the interior of which is used to accommodate a clamped object. The nut structure 44 moves along the threaded rod 42 toward the first curved wall 41, driving the second end of the second curved wall 43 toward one end of the first curved wall 41, thereby reducing the space required for the clamped object and ensuring a tighter connection and more secure clamping between the clamping ring and the object.

[0040] As an optional embodiment, a notch 45 is formed at the second end of the second curved wall 43 , and the threaded rod 42 extends into the notch 45 ; the nut structure 44 moves along one end of the threaded rod 42 close to the first curved wall 41 to tighten the clamp ring.

[0041] Based on the previous embodiment, in this embodiment, the nut structure 44 moves along the threaded rod 42 toward the first curved wall 41. The nut structure 44 contacts the edge of the notch 45, which acts as a fulcrum to drive the second end of the second curved wall 43 to move. The nut structure 44 moves along the threaded rod 42 away from the first curved wall 41, creating a clearance space. The second end of the second curved wall 43 can move away from the first curved wall 41, loosening the clamp ring.

[0042] like Figure 3-4As shown, based on the same inventive concept, an embodiment of the present application provides an LED display screen 7 assembly, which mainly includes a bracket 6 and an LED display screen 7 arranged at intervals, and a connecting piece of any one of the aforementioned embodiments; the connecting piece is connected to the bracket 6 and the LED display screen 7 respectively.

[0043] The LED display screen 7 assembly provided in the embodiment of the present application is locked and connected to the LED display screen 7 through a limiting protrusion, and is connected to the bracket 6 through a clamping structure 4. The relative positions of the rod core 1 and the rod sleeve 2 are adjusted, and the distance between the limiting protrusion and the clamping structure 4 is adjusted to connect the LED display screen 7 and the bracket 6. The structure of the connecting part is simple and the operation is convenient. The distance between the limiting protrusion and the clamping structure 4 is further reduced to achieve a close connection between the three and improve the stability of the connection.

[0044] As an optional embodiment, the LED display screen 7 includes a display device 71 and a frame 72. The display device 71 is fixed to the display side of the frame 72. A locking hole 73 is formed on the side of the frame 72 opposite the display side. The locking hole 73 is elliptical. The limiting protrusion of the connecting member extends into the locking hole 73 along the long axis of the locking hole 73. When the connecting member is rotated, the limiting protrusion of the connecting member abuts the edge of the locking hole 73 to form a locking connection.

[0045] Based on the aforementioned embodiments, in this embodiment, the connector and the bracket 6 are both arranged on the back side of the LED display screen 7, that is, on the side opposite to the display side. The locking hole 73 is recessed in the direction close to the display side. It should be noted that the elliptical shape of the locking hole 73 does not necessarily mean that it must be an elliptical shape, and it can be an approximately special-shaped hole. The limiting protrusion of the connector extends into the locking hole 73 along the long axis of the locking hole 73 and rotates clockwise or counterclockwise to an appropriate position. For example, along the axial projection of the locking rod 3, the limiting protrusion of the connector overlaps with the edge of the locking hole 73. In this way, when the locking rod 3 moves outward, the limiting protrusion abuts against the edge of the locking hole 73, and the limiting protrusion is stuck in the locking hole 73 to achieve locking of the connector and the LED display screen 7, ensuring that the two maintain a fixed relative position.

[0046] As an optional embodiment, a limiting portion is provided in the locking hole 73 and close to the edge of the locking hole 73 for limiting the relative position of the limiting protrusion and the locking hole 73 in the rotation direction of the connecting member.

[0047] With the above solution, when the connecting member rotates to abut against the limiting portion, it indicates that the connecting member has rotated to the optimal position, ie, the optimal position where the limiting protrusion is locked with the locking hole 73 .

[0048] As an optional embodiment, the bracket 6 includes a support column 61 , which is adapted to the clamping structure 4 of the connecting piece and is used to be connected to the clamping structure 4 of the connecting piece.

[0049] Based on the above embodiments, in this embodiment, the bracket 6 is rectangular, and the bracket 6 includes two relatively spaced apart pillars 61 and two relatively spaced apart end pillars. The two pillars 61 and the two end pillars are connected end to end. The length of the pillar 61 is longer than the end, and the pillar 61 is a cylinder to adapt to the above-mentioned clamping structure 4.
