[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] According to Figure 1 、 2 、3, 4, 5, 6, 7 as shown, in this embodiment, a computer information system operation terminal is proposed, including a terminal body 1, a display panel 2 and a control panel 3 are arranged on the front of the terminal body 1, and a plurality of control keys 10 are arranged on the control panel 3;

[0028] A limit strip 6 is provided at each of the upper and lower ends of the control panel 3. The limit strip 6 is fixedly connected to the control panel 3. Two sliding covers 4 are provided between the two limit strips 6. The upper and lower ends of the sliding cover 4 are respectively slidably connected to the two limit strips 6. A plurality of pressing diaphragms 5 are provided on the sliding cover 4, and each pressing diaphragm 5 corresponds to each control key 10 one by one;

[0029] The sliding cover 4 is slidably arranged between the two limit strips 6. When the two sliding covers 4 are mutually closed, the control keys 10 on the control panel 3 can be operated by pressing the pressing diaphragms 5 on the sliding cover 4. The sliding cover 4 covering the outside of the control panel 3 can protect the control keys 10 while not affecting the operation of the control keys 10, and improve the service life of the control panel 3 and the control keys 10.

[0030] A buckle structure for fixing the two sliding covers 4 is provided on one side where the two sliding covers 4 are close to each other. A limiting structure for restricting the separation of the sliding cover 4 and the limit strip 6 is provided at the connection between the limit strip 6 and the sliding cover 4.

[0031] The two sliding covers 4 are mutually closed through the buckle structure. When the sliding cover 4 and the pressing diaphragm 5 have problems and need to be replaced, the limit on the sliding cover 4 is released through the limiting structure, and the two sliding covers 4 can be taken out from between the two limit strips 6, and the sliding cover 4 is convenient to replace.

[0032] Specifically, sliders 7 are provided at the upper and lower ends of the sliding cover 4. The sliders 7 are fixedly connected to the sliding cover 4. A chute 12 allowing the sliders 7 to be inserted therein is provided on one side of the limit strip 6 facing the sliders 7. The chute 12 is slidably connected to the sliders 7. The sliders 7 are inserted into the chute 12 and can slide along the chute 12. The chute 12 cooperates with the sliders 7 to limit the sliding cover 4.

[0033] It is worth further explaining that the cross-section of the slider 7 is T-shaped, and the chute 12 is a T-shaped chute adapted to the slider 7. The advantage of this design is that the slider 7 inserted into the chute 12 can be more closely matched with the chute 12, and while sliding along the chute 12, the slider 7 will not shake back and forth in the chute 12.

[0034] Regarding the buckle structure:

[0035] The buckle structure includes a rubber ball 14 and a spherical card slot 15 provided between the two sliding covers 4. The rubber ball 14 is fixedly connected to one of the sliding covers 4. The spherical card slot 15 is opened on the side of the other rubber ball 14, and the rubber ball 14 is buckled with the spherical card slot 15.

[0036] After the two sliding covers 4 are mutually closed, the rubber ball 14 on one of the sliding covers 4 will be stuck into the spherical card slot 15 opened on the other sliding cover 4. The rubber ball 14, through the cooperation with the spherical card slot 15, prevents the two sliding covers 4 from separating when the operation terminal is in use. The buckle fixing method does not affect the opening of the sliding cover 4.

[0037] Regarding the limiting structure:

[0038] The limiting structure includes an adjusting bolt 9 and a limiting groove 8. The limiting groove 8 is opened on the upper end surface of the slider 7. The adjusting bolts 9 are threadedly connected to both ends of the limiting strip 6. The adjusting bolts 9 penetrate into the sliding groove 12 and the limiting groove 8, and the adjusting bolts 9 are slidably connected to the limiting groove 8.

[0039] When the sliding cover 4 slides horizontally between the two limiting strips 6, the slider 7 will slide along the sliding groove 12, and the adjusting bolt 9 will slide along the limiting groove 8 opened on the upper end surface of the slider 7. The adjusting bolt 9 can play a role in limiting the slider 7 to prevent the slider 7 from disengaging from the sliding groove 12. When the adjusting bolt 9 is screwed out of the limiting groove 8, by pulling the sliding cover 4 to both sides of the control panel 3, the sliding cover 4 can be completely removed from between the two limiting strips 6, which is convenient for disassembly and assembly.

[0040] Specifically, the adjusting bolt 9 includes a bolt cap 91 and a threaded post 92. The threaded post 92 is fixedly connected to the lower end of the bolt cap 91. The threaded post 92 is threadedly connected to the threaded hole 11 opened on the upper end surface of the limiting strip 6. The threaded hole 11 communicates with the sliding groove 12. A plurality of ribs 93 are provided on the outer side of the bolt cap 91. Each rib 93 is evenly arranged in the circumferential direction of the axis of the bolt cap 91. The ribs 93 are fixed to the bolt cap 91 and play a role in increasing the friction between the bolt cap 91 and the finger, so that the bolt cap 91 will not slip when being screwed.

[0041] In a preferred solution, a fixing block is provided on the back surface of the terminal body 1. A hook 13 is provided at the lower end of the fixing block. Both the terminal body 1 and the hook 13 are fixedly connected to the fixing block. The hook 13 can cooperate with the buckle on the external frame body, and the hanging and buckling installation method facilitates the taking and placing of the terminal body 1 at any time.

[0042] The working principle of this application:

[0043] The sliding cover 4 is slidably arranged between the two limiting strips 6. When the two sliding covers 4 are closed to each other, the buckle structure fixes the two sliding covers 4. By pressing the pressing diaphragm 5 on the sliding cover 4, the control keys 10 on the control panel 3 can be operated. The sliding cover 4 covering the control panel 3 can protect the control keys 10 while not affecting the operation of the control keys 10, and improve the service life of the control panel 3 and the control keys 10.

[0044] When the sliding cover 4 and the pressing diaphragm 5 have problems and need to be replaced, the limiting of the sliding cover 4 is released through the limiting structure, and the two sliding covers 4 can be taken out from between the two limiting strips 6, and the sliding cover 4 is convenient to replace.
