Description

Technical Field

[0001] This utility model relates to the field of monitoring display technology, and in particular to a liquid crystal splicing display screen for security monitoring. Background Technology

[0002] When a large number of surveillance cameras are deployed and real-time monitoring footage needs to be displayed, multiple sets of monitoring LCD screens need to be spliced ​​together. Since the existing monitoring LCD screens do not have a splicing structure in their casings, the alignment of multiple monitors can only be controlled by mounting brackets. This requires a high level of expertise from the installers. If the tilt angles of the multiple monitors are different, it will reduce the overall aesthetics, and the tilted screen will not be conducive to displaying the monitoring footage. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing technologies where the housing does not have a splicing structure, and to propose a liquid crystal splicing display screen for security monitoring.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a security monitoring LCD splicing display screen, including an outer frame, a back shell fixedly installed on one side of the outer frame by bolts, multiple sets of side holes through the outer wall of the outer frame for positioning and splicing between multiple sets of outer frames, an opening at one end of the back shell, a movable shell rotatably connected to the opening of the back shell by a hinge, and an electrical box fixedly installed on the outer end face of the back shell by screws.

[0006] Preferably, it also includes a rotating interface assembly, which includes a rotating shell, one end of which is integrally formed with a rotating shaft, the rotating shaft being rotatably mounted inside the electrical box, and the outer wall of the electrical box having a coupling interface.

[0007] Preferably, the electrical box has an integrally formed support column inside, and a spring retainer ball slides elastically inside the support column. The outer end face of the rotating shaft has multiple sets of slots, and the spring retainer ball can be partially engaged inside the slot.

[0008] Preferably, a limiting block is integrally formed at one end of the outer side of the two sets of slots located at the edge, the limiting block being used to limit the maximum rotation angle of the rotating shell.

[0009] Preferably, a set of rotating shells is provided at each of the left and right ends of the electrical box.

[0010] Preferably, the outer end face of the rear shell is also fixed with a mounting bracket by screws.

[0011] Preferably, a reinforcing block is also engaged inside the side hole near the top corner of the outer frame.

[0012] The present invention provides a liquid crystal splicing display screen for security monitoring, which has the following advantages:

[0013] By providing side holes in the outer frame, pins can be inserted into the side holes between two adjacent sets of outer frames, which can provide auxiliary positioning during installation. In use, the pins limit the rotation angle between multiple sets of outer frames, improving the overall flatness and thus enhancing the aesthetics. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 , Figure 2 , Figure 3 A security monitoring LCD splicing display screen includes an outer frame 1. A rear shell 4 is fixedly installed on one side of the outer frame 1 by bolts. Multiple sets of side holes 2 are opened through the outer wall of the outer frame 1. The side holes 2 are used for positioning and splicing between multiple sets of outer frames 1. One end of the rear shell 4 is open. A movable shell 5 is rotatably connected to the opening of the rear shell 4 by a hinge. An electrical box 7 is fixedly installed on the outer end face of the rear shell 4 by screws.

[0022] Furthermore, a mounting bracket 6 is also fixed to the outer end face of the rear shell 4 by screws.

[0023] Furthermore, a reinforcing block 3 is also inserted inside the side hole 2 near the top corner of the outer frame 1.

[0024] Working principle:

[0025] The mounting bracket 6 of the rear shell 4 is fixed to the wall or perforated board with bolts. When only a single monitor needs to be installed, the side hole 2 in the outer frame 1 can be used for lateral drilling and fixing. In this state, the reinforcing block 3 can be snapped into the side hole 2. The reinforcing block 3 has a threaded groove, so that the side hole 2 can be threaded with the bolt. When multiple monitors need to be spliced, a pin is inserted into the side hole 2 of one set of outer frames 1, and the side hole 2 of another set of outer frames 1 is aligned with the pin and inserted. This ensures that the two sets of outer frames 1 have the same horizontal position, improving the aesthetics of the splicing.

[0026] For ease of maintenance, the existing control circuit board for the display screen should be installed on the side with the movable housing 5. During maintenance, the movable housing 5 can be rotated open by the hinge to directly operate the control circuit board of the display screen. Example

[0027] In Embodiment 1, by opening side holes 2 in the outer frame 1, the flatness of the splicing between multiple sets of outer frames 1 is improved. However, in actual use, the main factors affecting the flatness between multiple sets of outer frames 1 also include the length of the data cable plug. Therefore, referring to... Figure 3 , Figure 4 , Figure 5 It also includes a rotating interface assembly, which includes a rotating shell 8. One end of the rotating shell 8 is integrally formed with a rotating shaft 9. The rotating shaft 9 is rotatably installed inside the electrical box 7. The outer wall of the electrical box 7 is provided with a coupling interface.

[0028] Furthermore, refer to Figure 5 The electrical box 7 has an integrally formed support column 12 inside, and a spring-loaded ball 13 is elastically slidable inside the support column 12. The outer end face of the rotating shaft 9 has multiple sets of slots 10, and the spring-loaded ball 13 can be partially engaged inside the slot 10.

[0029] Furthermore, a limiting block 11 is integrally formed on the outer end of the two sets of slots 10 located at the edge. The limiting block 11 is used to limit the maximum rotation angle of the rotating shell 8.

[0030] Furthermore, refer to Figure 3 The rotating shell 8 is provided at each of the left and right ends of the electrical box 7.

[0031] Working principle:

[0032] Rotate the rotating shell 8 along the rotating axis 9. At this time, the spring retaining ball 13 abuts against the inner wall of the slot 10 and is forced to retract into the support column 12. At this time, the rotating shell 8 can rotate and enter the next slot 10 in the rotation direction. This process is repeated until the outer wall of the support column 12 abuts against the limiting block 11, causing the rotating axis 9 to be unable to continue rotating.

[0033] The rotating shell 8 is rotated in the manner described above, so that the coupling interface in the rotating shell 8 faces the required angle. When the mounting bracket 6 is fixed to the perforated plate, the coupling interface in the rotating shell 8 can face the perforated plate directly since the wires can be directly threaded through it. When the mounting bracket 6 is fixed to the wall, the coupling interface in the rotating shell 8 can be oriented parallel to the wall so that the data cable plug does not contact the wall, thus preventing the assembly of the outer frame 1 and the rear shell 4 from being pushed up by the data cable plug on one side. At the same time, in order to reduce interference between the power supply line and the signal line, the rotating shell 8 is provided with two sets, which are located on both sides of the electrical box 7 respectively, to ensure sufficient electrical isolation distance.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
