On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present utility model and to be able to convey the scope of the present utility model completely to those skilled in the art.

[0047] Embodiment:

[0048] Referring to Figure 1 、 Figure 5 and Figure 9 , this embodiment provides a carbon fiber LED display screen box body with a quick-release hoisting lock and a radian lock, including a hoisting locking mechanism 2 and a left and right radian locking mechanism 1. The hoisting locking mechanism 2 includes an upper locking unit 21 and a lower locking unit 22 installed at both ends of the display box body 3. The upper locking unit 21 of the previous display box body 3 is used for hoisting and locking with the lower locking unit 22 of the next display box body 3. The left and right radian locking mechanism 1 includes a left locking unit 11 and a right locking unit 12 correspondingly installed on both sides of the display box body 3. The left locking unit 11 on the left display box body 3 is used for detachably connecting with the right locking unit 12 on the right display box body 3 and adjusting the left and right splicing radian, Figure 9Only one display box 3 is shown, along with its corresponding left locking unit 11 on the left side of the display box 3 and upper locking unit 21 on the top side of the display box 3.

[0049] See Figures 1 to 4 The locking unit 21 includes an upper lock housing 211 and a locking plate 212. The upper lock housing 211 has an installation space. One end of the locking plate 212 is movably disposed within the upper lock housing 211, while the other end protrudes from a side opening of the upper lock housing 211. The locking plate 2122 has a lock hole 2120 with a large hole and a small hole, which are interconnected. The lock hole 2120 is generally gourd-shaped. The diameter of the neck 2220 is less than the diameter of the small hole, which is less than the diameter of the large hole.

[0050] When the lock plate 212 is moved outward so that the neck 2220 of the lock cylinder 222 engages with the small hole, the lock cylinder 222 and the lock plate 212 are locked together, and the lock cylinder 222 no longer moves longitudinally. When the lock plate 212 is moved inward, the lock cylinder 222 is placed in the large hole. At this time, the first movable handle 224 can be rotated to drive the lock cylinder 222 to move downward and exit the lock hole 2120, thereby unlocking the upper locking unit 21 and the lower locking unit 22.

[0051] See Figures 3 to 4 The lower locking unit 22 includes a lower lock housing 221, a lock cylinder 222, an external threaded sleeve 223, and a first movable handle 224. The lower lock housing 221 has an installation space in which the lock cylinder 222, external threaded sleeve 223, and first movable handle 224 are installed. A positioning post 225 is installed on the top surface of the lower lock housing 221, and a corresponding positioning hole is provided on the upper lock housing 211. One end of the lock cylinder 222 is fixedly fitted together with the external threaded sleeve 223, and the other end passes through the external threaded sleeve 223 and extends out from the top surface of the lower lock housing 221. The upper end of the lock cylinder 222 is recessed inward along its circumferential direction, forming a neck 2220 for engaging with a small hole. One end of the first movable handle 224 has an internal threaded hole, which threadedly engages with the external threaded sleeve 223 and is movably installed in the lower lock housing 221. The other end extends out from the lower lock housing 221.

[0052] In some feasible solutions, the locking plate 212 comprises two parts, which are generally right-angled in shape. One part, where the lock hole 2120 is located, is on a horizontal plane, and the other part forms an operating end for horizontally moving the locking plate 212.

[0053] In actual production applications, the outer wall of the lock cylinder 222 is provided with a long groove along its axial direction. The bolt passes through the external threaded sleeve 223 and abuts against the appropriate position of the long groove to fix the external threaded sleeve 223 and the lock cylinder 222 together and prevent the lock cylinder 222 from rotating.

[0054] Furthermore, to enhance the user experience, the locking unit 21 also includes a reset assembly, which comprises a cap 2131, an elastic element 2132, and a movable element 2133. One end of the elastic element 2132 abuts against the cap 2131, and the other end abuts against the movable element 2133. The movable element 2133 is slidably disposed within the cap 2131, and its lower end abuts against the top surface of the lock cylinder 222. The lock plate 212 is positioned between the inner bottom surface of the upper lock housing 211 and the cap 2131.

[0055] The top surface of the upper locking shell 211 and the lower end of the lower locking shell 221 are respectively connected to the back support 31 of the display cabinet 3, and the back support 31 helps the display cabinet 3 stand upright on the ground.

[0056] See Figures 6 to 8 In some feasible solutions, the left locking unit 11 includes an arc-shaped outer shell 111, an arc-shaped inner shell 112 and an arc adjustment module. One end of the arc-shaped inner shell 112 is placed in the arc-shaped outer shell 111, and the other end of the arc-shaped inner shell 112 is an arm 1121. The arm 1121 is provided with a groove for fitting with the locking ring 125 described later.

[0057] The curvature adjustment module adjusts the relative position of the curved outer shell 111 and the curved inner shell 112 to change the splicing curvature of the display cabinet 3 on the left.

[0058] The arc-shaped outer shell 111 is provided with a sliding groove, and the outer walls on both sides of the sliding groove are provided with a serrated structure with corresponding graduations. The arc adjustment module includes a wrench 1131, a T-shaped fitting 1132, a spring, and a mounting post 1133. One end of the mounting post 1133 extends into the arc-shaped inner shell 112 from the sliding groove and engages with the arc-shaped inner shell 112. The T-shaped fitting 1132 is fitted onto the middle of the mounting post 1133. One end of the spring abuts against the T-shaped fitting 1132, and the other end abuts against the mounting post 1133. The step of the T-shaped fitting 1132 is used to press against the serrated structure. The wrench 1131 is placed on the top surface of the T-shaped fitting 1132 and is rotatably connected to the upper end of the mounting post 1133. The end of the wrench 1131 that contacts the T-shaped fitting 1132 has an arc protrusion. By turning the wrench 1131, the step of the T-shaped kit 1132 can be brought into contact with or away from the serrated structure, thereby adjusting the splicing curvature of the display box 3 and realizing the splicing of the inner arc, outer arc and plane.

[0059] See Figures 5 to 8 The right locking unit 12 includes a fixed mounting part 121, a second movable handle 122, and a locking ring 125.

[0060] The fixed mounting component 121 is installed on the display cabinet 3 by bolts. The left end of the second movable handle 122 is rotatably connected to the fixed mounting component 121 through the first rotating shaft 126. The locking ring 125 is rotatably connected to the middle part of the second movable handle 122 through the second rotating shaft 127. The locking ring 125 is used to lock into the groove of the arm 1121 of the arc-shaped inner shell 112 so that the left locking unit 11 and the right locking unit 12 are connected together.

[0061] Furthermore, the right locking unit 12 also includes a torsion spring 123 and a handle fastener 124. The fixed mounting member 121 is provided with a first step 1211. The handle fastener 124 is generally right-angled, with one end passing through the second movable handle 122 and rotatably connected to the second movable handle 122 via a third pivot 128. It is also provided with a second step 1241 that matches the first step 1211. The other end of the handle fastener 124 is positioned above the movable groove on the outside of the second movable handle 122. A torsion spring 123 is mounted on the second rotating shaft 127, with one end abutting against the handle fastener 124, providing a rightward thrust to the second step 1241. Therefore, without external force, the second step 1241 remains engaged with the first step 1211, keeping the second movable handle 122 stationary. By placing the locking ring 125 in the groove of the arm 1121 and rotating the second movable handle 122 until the second step 1241 engages with the first step 1211, the connection between the left locking unit 11 and the right locking unit 12 is revealed. Conversely, by pressing the handle fastener 124 to disengage the second step 1241 from the first step 1211, the second movable handle 122 can be rotated around the first rotating shaft 126, thereby releasing the locking connection of the locking ring 125 to the arm 1121.

[0062] The carbon fiber LED display cabinet of this application is made of carbon fiber material, making it lighter, thinner, and more stable.
