[0004] Most of the existing live displays are equipped with a self-test unit. For example, the above-mentioned existing self-test live displays are provided with a magnetic connector and a magnetic interface, and the operation panel is connected to the power supply inside the shell by magnetic attraction, so that when the operation panel is repaired, there is no need to remove the live display as a whole. In the specific implementation process, due to the poor stability of the magnetic fit, a reinforcement component consisting of a card block and a card slot is also provided between the front cover and the operation panel, and another connecting component between the shell and the mounting frame. The reinforcement component can be optimized and combined with the connecting component. Therefore, it is urgent to propose a corresponding self-test live display to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to propose a self-checking type charged display.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A self-test type live display includes a shell, a self-test unit and an operation panel. The outer wall of the shell is fixedly connected to a front cover, and the front cover is detachably connected to the operation panel. The outer wall of the shell is sleeved with a mounting frame, and a mounting hole is provided on the top of the mounting frame. A protrusion is fixedly connected to the side of the mounting frame close to the operation panel, and a positioning component for positioning the front cover and the operation panel is provided between the protrusion and the front cover.

[0008] Preferably, the outer wall of the protruding piece is engaged with the outer wall of the front cover through a slot.

[0009] Preferably, a clamping strip is fixedly connected to the inner surface wall of the installation frame, and the outer surface wall of the clamping strip is combined with the outer surface wall of the shell through a coupling groove.

[0010] Preferably, the installation frame is a mouth-shaped structure, and the outer wall of the installation frame abuts against the rear end surface of the front cover.

[0011] Preferably, the positioning assembly includes a locking rod, the outer wall of the locking rod is first screwed with the inner wall of the protruding piece, the locking rod passes through the mounting frame through a through hole, and the open end of the locking rod abuts against the outer wall of the operation panel.

[0012] Preferably, the inner surface wall of the protruding piece is interference-fitted with a sealing plug, and the inner surface wall of the sealing plug abuts against the outer surface wall of the locking rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, the mounting frame is connected to the external support by fasteners, and the locking rod is rotated to separate its open end from the outer wall of the operation panel, and the open end of the locking rod is still engaged with the through-hole. At this time, the operation panel can be independently disassembled and assembled from the front side, and the locking rod can limit the position of the front cover and the shell so that the front cover and the shell will not move longitudinally. Similarly, the locking rod is continued to be rotated to separate it from the through-hole. At this time, the front cover is pulled until the card strip is separated from the coupling groove, so that the front cover and the shell can be separated, thereby ensuring the stability of the cooperation between the operation panel, the front cover and the shell, and merging the reinforcement component and the connection component in the original technology, thereby ensuring the compactness of the self-test type live display structure and the convenience of operation.

[0015] 2. In the present application, the locking rod is rotated so that it is screwed into the inner surface wall of the protrusion until the locking rod passes through the through hole and its open end abuts against the outer surface wall of the operation panel, thereby fixing the position of the operation panel, the front cover and the shell. Then the sealing plug can be inserted into the inner surface wall of the protrusion. The interference fit ensures the stable position of the sealing plug. While the sealing plug isolates the locking rod, the friction generated between the sealing plug and the locking rod can effectively limit the loosening of the locking rod.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A self-testing type live display comprises a housing 1, a self-testing unit, and an operation panel 3. A front cover 2 is fixedly connected to the outer wall of the housing 1, and the front cover 2 is detachably connected to the operation panel 3. A mounting frame 4 is sleeved on the outer wall of the housing 1, and a mounting hole 5 is formed at the top of the mounting frame 4. A protrusion 6 is fixedly connected to the side of the mounting frame 4 near the operation panel 3. A positioning assembly for positioning the front cover 2 and the operation panel 3 is provided between the protrusion 6 and the front cover 2;

[0025] The mounting frame 4 is connected to the external support by fasteners, and the locking rod 11 is rotated to separate its open end from the outer wall of the operation panel 3, and the open end of the locking rod 11 is still engaged with the through-hole 12. At this time, the operation panel 3 can be independently disassembled and assembled from the front side, and the locking rod 11 can limit the position of the front cover 2 and the shell 1, so that the front cover 2 and the shell 1 will not move longitudinally. Similarly, the locking rod 11 is continued to be rotated to separate it from the through-hole 12, and the front cover 2 is pulled until the card strip 7 is disengaged from the coupling groove 10, so that the front cover 2 and the shell 1 can be separated. This ensures the stability of the operation panel 3, the front cover 2 and the shell 1, while combining the reinforcement component and the connection component in the original technology, ensuring the compactness of the self-test type live display structure and the convenience of operation.

[0026] It should be noted that the self-test unit adopts the self-test module mentioned in application number CN202220455700.X, which will not be described here.

[0027] Specifically, such as Figure 2 and Figure 4As shown, the outer wall of the protruding piece 6 is engaged with the outer wall of the front cover 2 through the card slot 9, and the inner wall of the mounting frame 4 is fixedly connected with a card strip 7. The outer wall of the card strip 7 is combined with the outer wall of the shell 1 through the coupling groove 10, so as to ensure the smoothness of the outer contour of the live display, and the coordination between the protruding piece 6 and the card slot 9 and the card strip 7 and the coupling groove 10 can ensure the stability of the connection between the live display and the mounting frame 4. The mounting frame 4 has a mouth-shaped structure, and the outer wall of the mounting frame 4 abuts against the rear end face of the front cover 2, so as to further ensure the stability of the coordination between the mounting frame 4 and the shell 1. The positioning component includes a locking rod 11. The outer wall of the locking rod 11 is first screwed together with the inner wall of the protruding piece 6. The locking rod 11 passes through the mounting frame 4 through the through hole 12. The open end of the locking rod 11 abuts against the outer wall of the operation panel 3. The reinforcement component and the connection component in the original technology are combined to ensure the compactness of the self-test type live display structure and the convenience of operation.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the inner surface wall of the protrusion 6 is interference-fitted with a sealing plug 8, and the inner surface wall of the sealing plug 8 abuts against the outer surface wall of the locking rod 11. The locking rod 11 is rotated to screw it into the inner surface wall of the protrusion 6 until the locking rod 11 passes through the through-hole 12 and its open end abuts against the outer surface wall of the operation panel 3, thereby fixing the position of the operation panel 3, the front cover 2 and the shell 1. Then the sealing plug 8 can be inserted into the inner surface wall of the protrusion 6. The interference fit ensures the stable position of the sealing plug 8. While the sealing plug 8 isolates the locking rod 11, the friction generated between the sealing plug 8 and the locking rod 11 can effectively limit the loosening of the locking rod 11.

[0029] Working principle: The mounting frame 4 is connected to the external support member through fasteners, and the locking rod 11 is rotated to make its open end disengage from the outer wall of the operation panel 3, and the open end of the locking rod 11 is still engaged with the through-hole 12. At this time, the operation panel 3 can be independently disassembled and assembled from the front side, and the locking rod 11 can limit the position of the front cover 2 and the shell 1, so that the front cover 2 and the shell 1 will not move longitudinally. Similarly, continue to rotate the locking rod 11 to disengage from the through-hole 12, and then pull the front cover 2 until the card strip 7 disengages from the coupling groove 10, so that the front cover 2 and the shell 1 can be separated, thereby ensuring the stability of the operation panel 3, the front cover 2 and the shell 1. At the same time, the reinforcement components and the connection components in the original technology are combined to ensure the compactness of the structure of the self-test type live display and the convenience of operation. The locking rod 11 is rotated to screw it into the inner wall of the protrusion 6 until the locking rod 11 passes through the through-hole 12 and its open end abuts against the outer wall of the operation panel 3, thereby fixing the position of the operation panel 3, the front cover 2 and the shell 1. Then the sealing plug 8 can be inserted into the inner wall of the protrusion 6. The interference fit ensures the stable position of the sealing plug 8. While the sealing plug 8 isolates the locking rod 11, the friction generated between the sealing plug 8 and the locking rod 11 can effectively limit the loosening of the locking rod 11.
