[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] See also Figures 5 to 8 The fixing mechanism 10 provided in one embodiment of the present invention is used to install the LED display screen 300. The fixing mechanism 10 includes a support 100 and a hanging member 200. The support 100 has a first mounting surface 110 and a second mounting surface 120 that are arranged opposite to each other. The first mounting surface 110 and the second mounting surface 120 can be arranged parallel to each other. For example, the first mounting surface 110 is the upper surface of the support 100, and the second mounting surface 120 is the lower surface of the support 100. The hanging member 200 can be arranged on the first mounting surface 110, and the hanging member 200 can be detachably connected with the support 100.

[0029] See also Figure 1 When the hanging member 200 is disassembled from the support 100, that is, the hanging member 200 is completely unloaded and separated from the support 100, thereby eliminating the interference caused by the hanging member 200, the LED display screen 300 can be carried on the first installation surface 110, and the support 100 carrying the LED display screen 300 can be placed on a support platform such as the ground, thereby realizing the seat-type installation of the LED display screen 300 by the fixing mechanism 10. Obviously, for the seat-type installed LED display screen 300, in the vertical direction, the LED display screen 300 is located above the support 100, and the LED display screen 300 directly applies vertical downward pressure to the support 100, and the support 100 directly applies vertical downward pressure to the support platform. In other words, the fixing mechanism 10 balances the gravity of the LED display screen 300 through the upward vertical upward support force.

[0030] See also Figure 5 When the suspension member 200 is connected to the support 100, that is, the suspension member 200 is fixed on the first installation surface 110, the LED display screen 300 can be directly suspended on the second installation surface 120. At this time, the suspension member 200 can be hung on a support such as a wall, thereby realizing the hanging installation of the LED display screen 300 by the fixing mechanism 10. Obviously, for the hanging installation of the LED display screen 300, in the vertical direction, the LED display screen 300 is located below the support 100, and the LED display screen 300 directly applies a vertical downward pulling force to the support 100. Both the support 100 and the suspension member 200 directly apply a vertical downward pulling force to the support. In other words, the fixing mechanism 10 balances the gravity of the LED display screen 300 by a vertical upward pulling force.

[0031] When the hanging member 200 is unloaded from the support 100, the LED display screen 300 can be installed in a seated manner on the first installation surface 110; when the hanging member 200 is connected to the support 100, the LED display screen 300 can be installed in a hanging manner on the second installation surface 120. Therefore, according to the actual needs, the fixing mechanism 10 can be used for hanging and seated installation of the LED display screen 300 in different occasions, thereby improving the versatility of the fixing mechanism 10 for installing the LED display screen 300 and reducing its installation cost while improving the convenience of installing the LED display screen 300.

[0032] The support 100 can be made of aluminum alloy or steel. The support 100 can be roughly in the shape of a hollow cuboid, that is, the support 100 is a tubular structure with a cavity 101 disposed inside. The cavity 101 has an opening at the end of the support 100, and the cavity 101 is connected to the outside through the opening. For the hanging installation of the LED display screen 300, the hollow support 100 can save materials and reduce the weight of the entire fixing mechanism 10, ensuring the safety of the hanging installation. At the same time, for the seat installation of the LED display screen 300, the hollow support 100 has high compressive and torsional strength, preventing the support 100 from plastic deformation under the pressure of the LED display screen 300. The support 100 can be integrally formed by injection or casting, or can be spliced ​​by welding.

[0033] See also Figures 5 to 8In some embodiments, the suspension member 200 includes a connecting rod 220 and a hanging ring 210. The connecting rod 220 may be in a strip shape, and the hanging ring 210 may be in a ring shape. The hanging ring 210 is fixedly connected to the connecting rod 220, and the hanging ring 210 is used to be hung on a support. The connecting rod 220 and the support 100 may be detachably connected. For example, an external thread is provided on the connecting rod 220, and the connecting rod 220 is threadedly connected to the support 100; or, the connecting rod 220 and the support 100 are snap-connected. When the hanging installation is adopted, the hanging ring 210 is fixed on the support 100, and when the seat installation is adopted, the hanging ring 210 is separated from the support 100. The suspension member 200 may be made of aluminum alloy or steel.

[0034] See also Figures 5 to 8 In some embodiments, the fixing mechanism 10 further includes a support leg 400, the support leg 400 is connected to the support 100, the support 100 has a support surface 421, the support surface 421 is pressurized on a support platform such as the ground, and when the installation position of the support leg 400 and the support 100 changes, the distance between the support surface 421 and the support 100 can be changed. For example, the support leg 400 includes a screw rod 410 and a support head 420 connected to each other, the support surface 421 is arranged on the support head 420, the screw rod 410 is directly connected to the support 100, and when the support surface 421 contacts the ground, the screw rod 410 is rotated to change the distance between the support 100 and the ground (corresponding to the support surface 421), thereby adjusting the installation height of the LED display screen 300 in a seat-mounted state relative to a support plane such as the ground,

[0035] See also Figures 5 to 8 In some embodiments, the edge of the second mounting surface 120 is recessed toward the first mounting surface 110 to form a step surface 130, and the support leg 400 is disposed on the step surface 130. By providing the step surface 130, at least the following beneficial effects are achieved:

[0036] First, a recessed platform 131 is provided at the edge of the support 100 for avoiding the position, and the support leg 400 can be located in the recessed platform 131. For example, when the screw rod 410 of the support leg 400 is rotated clockwise, the support head 420 moves toward the direction close to the first mounting surface 110, so that the support surface 421 is closer to the first mounting surface 110 relative to the second mounting surface 120. In short, the support head 420 is accommodated in the recessed platform 131. During the process of the support 100 performing hanging installation on the LED display screen 300, the entire support leg 400 will not interfere with the LED display screen 300 installed on the second mounting surface 120, ensuring that the surface of the LED display screen 300 is in close contact with the second mounting surface 120. Of course, the distances from the support surface 421 and the second mounting surface 120 to the first mounting surface 110 can be equal (that is, the support surface 421 and the second mounting surface 120 are flush). At this time, the entire support leg 400 will also not interfere with the LED display screen 300 installed on the second mounting surface 120. Also refer to Figures 1 to 4 When the screw rod 410 of the support leg 400 is rotated counterclockwise, the support head 420 moves in a direction away from the first mounting surface 110, so that the support surface 421 is further away from the first mounting surface 110 relative to the second mounting surface 120. During the process of the support 100 performing a seat-type installation on the LED display screen 300, the support surface 421 of the support leg 400 can directly contact the ground. When the supporting plane such as the ground is in an uneven state, the screw rod 410 of the support leg 400 is rotated to adjust the installation position of the support 100 relative to the supporting plane such as the ground, thereby ensuring that the entire support 100 will not tilt relative to the supporting plane such as the ground.

[0037] Second, when the fixing mechanism 10 switches between the hanging installation and the base installation of the LED display screen 300, the support leg 400 can always be fixed on the support 100, avoiding the possibility of the support leg 400 being lost due to improper storage after unloading, thereby improving the convenience of using the fixing mechanism 10.

[0038] See also Figure 5 In some embodiments, the fixing mechanism 10 further includes a positioning column 500, which is disposed on the first mounting surface 110 of the support 100. For example, two positioning columns 500 and one hanging member 200 may be installed on each support 100, and the hanging member 200 is located between the two positioning columns 500. The positioning member and the hanging member 200 may be arranged on the same straight line, and the distance from the hanging member 200 to each positioning column 500 may be equal. For the seat installation of the LED display screen 300, when the LED display screen 300 is carried on the first mounting surface 110, the positioning column 500 connected to the support 100 will be inserted into the LED display screen 300, thereby realizing the accurate positioning of the LED display screen 300 relative to the support 100 and ensuring the installation accuracy of the LED display screen 300.

[0039] In some embodiments, a mounting hole is provided on the second mounting surface 120 of the support 100, and the mounting hole is connected to the cavity 101 in the support 100. During the hanging installation of the LED display screen 300, a portion of the LED display screen 300 (corresponding to the locking rod 600 mentioned later) is passed through the mounting hole, and a locking block is installed in the cavity 101 of the support 100. The portion of the LED display screen 300 cooperates with the locking block, so that the LED display screen 300 is stably and reliably hung on the support 100, thereby realizing the hanging installation of the LED display screen 300 on the fixed structure.

[0040] Also refer to 3. Figures 5 to 7 In some embodiments, the first mounting surface 110 has a first edge 111, a second edge 112 and a third edge 113, the first edge 111 and the second edge 112 are arranged in parallel, the number of the third edges 113 is two, one of the third edges 113 is connected to one end of the first edge 111 and the second edge 112, and the other third edge 113 is connected to the other end of the first edge 111 and the second edge 112, and the first edge 111 and the third edge 113 intersect at an acute angle A. At this time, the first side 111, the second side 112 and the third side 113 together form an isosceles trapezoid, that is, the first mounting surface 110 is an isosceles trapezoidal surface. Therefore, when multiple supports 100 are assembled together, the third sides 113 of each support 100 are connected to each other, that is, a certain angle can be formed between each support 100 (that is, non-linear arrangement), so that the multiple LED display screens 300 after splicing form a three-dimensional curved screen. For example, when the three-dimensional curved screen is bent in the direction away from the display surface, the three-dimensional curved screen is an outer arc three-dimensional display screen, and when the three-dimensional curved screen is bent in the direction of the display surface, the three-dimensional curved screen is an inner arc three-dimensional display screen; when each support 100 is arranged in a straight line, the multiple LED display screens 300 after splicing form a two-dimensional flat screen. Of course, in order to ensure the smooth assembly of each support 100, the shape of the second mounting surface 120 can be similar to that of the first mounting surface 110, that is, it is also an isosceles trapezoidal surface.

[0041] The present invention also provides a splicing device 20, which includes an LED display screen 300 and the above-mentioned fixing mechanism 10, and the LED display screen 300 is installed on the fixing mechanism 10. When the LED display screen 300 is carried on the first mounting surface 110 of the fixing mechanism 10, the LED display screen 300 is in a seat-type installation state; when the LED display screen 300 is suspended on the second mounting surface 120 of the fixing mechanism 10, the LED display screen 300 is in a hanging-type installation state. For the hanging-type installation of the LED display screen 300, a locking rod 600 is provided on the LED display screen 300. When the LED display screen 300 is suspended on the second mounting surface 120, the locking rod 600 is inserted into the mounting hole of the support 100, and the locking rod 600 is connected to the locking block located in the support 100, so that the LED display screen 300 is stably and reliably hung on the support 100.

[0042] When multiple splicing devices 20 are spliced ​​together, multiple LED display screens 300 with smaller display screens can be spliced ​​together to form an LED display screen 300 with a larger display screen. At the same time, by setting the first mounting surface 110 as an isosceles trapezoidal surface, the LED display screen 300 with a larger display screen formed by splicing can be a curved screen or a flat screen according to actual needs, thereby realizing the diversification of splicing of the splicing devices 20.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
