[0035] In the embodiment, the connecting sleeve 10 is arranged between the display device 40 and the support 50, and the connecting sleeve 10 extends along the front-rear direction of the display device 40. The avoiding gap 14 is located between the display device 40 and the support 50, so that the operating personnel can operate the operating part 22 on one side of the display screen.

[0036] In other embodiments, the connecting sleeve 10 is fixedly connected with the support 50. When the fastening member 20 is in the clamping state, the stop protrusion 21 moves close to the first end of the connecting sleeve 10 to restrict the display device 40 between the stop protrusion 21 and the connecting sleeve 10. When the fastening member 20 is in the loosening state, the stop protrusion 21 moves away from the first end of the connecting sleeve 10 to enable the display device 40 to be taken out from between the stop protrusion 21 and the connecting sleeve 10.

[0037] As shown in Figures 1 to 6 The fastening member 20 is rotatably arranged at the first end of the connecting sleeve 10, and the fastening member 20 is rotated to switch between the clamping state and the loosening state. The fastening member 20 is provided with an external thread segment 23 located between the stop protrusion 21 and the operation portion 22, and the first end of the connecting sleeve 10 is provided with an internal thread hole 111, the external thread segment 23 is threadedly matched with the internal thread hole 111, and the fastening member 20 is rotated to switch between the clamping state and the loosening state. The external thread segment 23 on the fastening member 20 can be threadedly matched with the internal thread hole 111 of the connecting sleeve 10, so that the operator can adjust the distance between the stop protrusion 21 and the connecting sleeve 10 by rotating the fastening member 20, thereby realizing the connection or separation between the display device 40 and the support 50. This design is simple in structure, easy to process, and improves the connection precision and stability, and also makes the disassembly and assembly operation of the display device 40 and the support 50 more simple and convenient.

[0038] In other embodiments, the fastening member 20 can move along the axial direction thereof to switch between the clamping state and the loosening state.

[0039] As shown in Figures 1 to 6 The circumferential surface of the operation portion 22 includes a plurality of cutting surfaces 221 connected in sequence. In this way, the tool is conveniently abutted with the cutting surfaces 221 to drive the operation portion 22 to rotate, thereby driving the fastening member 20 to rotate. The operation portion 22 is provided with a thimble 222. The thimble 222 is provided to facilitate the operator to insert the tool into the thimble 222 to apply force to the operation portion 22 by the tool to drive the operation portion 22 to rotate, thereby driving the fastening member 20 to rotate. The above-mentioned arrangement improves the convenience and efficiency of rotating the fastening member 20, and further simplifies the disassembly and assembly operation of the display device 40 and the support 50.

[0040] In the present embodiment, the thimble 222 is a plurality of thimbles, and the plurality of thimbles 222 are arranged at intervals along the circumferential direction of the operation portion 22. The plurality of thimbles 222 are arranged one by one on the plurality of cutting surfaces 221.

[0041] In other embodiments, the circumferential surface of the operation portion 22 includes a plurality of cutting surfaces 221 connected in sequence. Alternatively, the operation portion 22 is provided with a thimble 222.

[0042] As shown in Figures 1 to 6As shown, the connecting sleeve 10 comprises a sleeve body 11 and an end plate 12 which are spaced along the axis of the connecting sleeve 10, and a connecting plate 13 which is connected between the side wall of the sleeve body 11 and the end plate 12. The connecting plate 13, the sleeve body 11 and the end plate 12 form an avoiding gap 14 therebetween, and the fastening member 20 passes through the sleeve body 11. The end plate 12 is fixedly connected with the display device 40. The arrangement of the sleeve body 11, the end plate 12 and the connecting plate 13 not only enhances the overall structural strength of the connecting sleeve 10, but also forms the avoiding gap 14 through the connecting plate 13, the sleeve body 11 and the end plate 12, which facilitates the operator to operate the operating part 22, thereby simplifying the disassembly and assembly operation of the display device 40 and the support 50, and facilitating the maintenance.

[0043] In the present embodiment, the internal thread is arranged on the inner hole wall of the sleeve body 11 to form an internally threaded hole 111.

[0044] In other embodiments, the end plate 12 is fixedly connected with the support 50.

[0045] As shown in the drawings, Figures 1 to 6 The connecting structure of the display screen further comprises a screw rod 30 which is arranged on the surface of the end plate 12 away from the sleeve body 11, and the screw rod 30 is fixedly connected with the display device 40. The arrangement of the screw rod 30 improves the stability and reliability of the connection between the end plate 12 and the display device 40. The cooperation of the screw rod 30 and the end plate 12 further enhances the connection strength between the display device 40 and the support 50, and improves the use safety in various environments.

[0046] In other embodiments, the screw rod 30 is fixedly connected with the support 50.

[0047] As shown in the drawings, Figures 1 to 6 The connecting sleeve 10 is cylindrical, and the avoiding gap 14 has an arc-shaped opening which extends along the circumference of the connecting sleeve 10, and the length of the arc-shaped opening is A, which is greater than or equal to half of the circumference of the connecting sleeve 10. The above arrangement effectively increases the range of movement of the operating tool 60 such as a wrench in the avoiding gap 14, so that the operator can more flexibly and efficiently use the tool to operate the fastening member 20.

[0048] As shown in the drawings, Figures 1 to 6 The stopper protrusion 21 is a magnetic member. The arrangement of the stopper protrusion 21 as a magnetic member enables the magnetic stopper protrusion 21 to quickly respond and generate an attractive force when the display device 40 approaches the support 50, thereby assisting the preliminary positioning and fixing of the display device 40 and the support 50, reducing the physical demand of manual operation and reducing the labor intensity.

[0049] In other embodiments, the magnetic stop protrusion 21 can magnetically attach the display device 40 to the bracket 50. Thus, the display connection structure can be secured to the bracket 50 by the screw fastener 20 passing through it. Alternatively, the display connection structure can be secured to the bracket 50 by the magnetic engagement of the screw fastener 20 with the bracket 50. This enriches the connection methods between the display device 40 and the bracket 50, making the use of the display connection structure more flexible.

[0050] This application also provides a display screen, such as Figures 1 to 8 As shown, the display screen includes a display device 40, a bracket 50, and a connecting structure. The connecting structure is used to connect the display device 40 and the bracket 50, and the connecting structure is the aforementioned display screen connection structure. Since the aforementioned display screen connection structure can solve the problem of complex assembly and disassembly operations between the display device and the bracket in related technologies, the display screen with this connection structure can solve the same technical problem.

[0051] like Figure 8 As shown, the bracket 50 is provided with a mounting hole 51, which includes a first hole segment 511 and a second hole segment 512 communicating with the first hole segment 511. The first hole segment 511 is located above the second hole segment 512. A stop protrusion 21 can pass through the first hole segment 511 to allow the tightening member 20 to be located within the first hole segment 511. When the tightening member 20 moves from the first hole segment 511 to the second hole segment 512, the stop protrusion 21 engages with the bracket 50. In this way, the arrangement of the first hole segment 511 and the second hole segment 512 of the mounting hole 51 simplifies the connection operation between the connecting structure and the bracket 50. By allowing the stop protrusion 21 of the connecting structure to pass through the first hole segment 511 of the bracket 50, the connecting structure can penetrate the bracket 50. Under the action of the display device 40's own weight, the tightening member 20 can move from the first hole segment 511 to the second hole segment 512, and the tightening member 20 can be held within the second hole segment 512. When the tightening member 20 is inserted into the second hole section 512, the stop protrusion 21 can cooperate with the stop of the bracket 50 at the second hole section 512, so that the bracket 50 at the second hole section 512 is restricted between the stop protrusion 21 and the connecting sleeve 10. Through the above improvements, not only is the disassembly and assembly operation of the display device 40 and the bracket 50 simplified, but also the convenience, reliability and stability of the connection structure when connected to the bracket 50 are improved, making it suitable for display devices 40 of various environments and different sizes.

[0052] In this embodiment, the mounting hole 51 is a gourd-shaped hole, and the diameter of the first hole segment 511 is larger than the diameter of the second hole segment 512.

[0053] like Figure 1 and Figure 3As shown, the display screen further comprises an operation tool 60. The operation tool 60 comprises a first plate segment 61, a second plate segment 62 arranged in parallel with the first plate segment 61, and a third plate segment 63 connected between the first plate segment 61 and the second plate segment 62. The first plate segment 61 and the second plate segment 62 are arranged in parallel and connected through the third plate segment 63, so that the operation tool 60 forms a bent shape, facilitating the operator to approach the operation part 22 from different angles in a space-limited environment when using the operation tool 60, and improving the flexibility of operation at various angles. The peripheral surface of the operation part 22 comprises a plurality of cut surfaces 221 connected in sequence, and the end of the first plate segment 61 away from the third plate segment 63 is provided with a clamping notch 611, and the side wall of the clamping notch 611 has a plurality of abutting planes 612 matched with the plurality of cut surfaces 221. The plurality of cut surfaces 221 and the plurality of abutting planes 612 are arranged to facilitate the abutting planes 612 of the operation tool 60 to abut and match with the cut surfaces 221, so as to drive the rotating part 20 to move by applying force to the cut surfaces 221 through the abutting planes 612. The operation part 22 is provided with a plug hole 222, and the end of the second plate segment 62 away from the third plate segment 63 is provided with a plug protrusion 621 capable of being plugged with the plug hole 222.
