Description

Technical Field

[0001] This invention relates to the field of display screen technology, and more specifically, to a display screen housing and a display screen having the same. Background Technology

[0002] The display cabinet includes a cabinet body and a front cover. Components are installed on the cabinet body, and the front cover is placed on the components and connected to the cabinet body.

[0003] In related technologies, some display screen cabinets use a row of screws to connect the cabinet body and the front cover. When repairing components, this makes disassembling the front cover and the cabinet body time-consuming and inconvenient. Other display screen cabinets use magnets to attract the cabinet body and the front cover. The magnetic attraction makes the connection between the cabinet body and the front cover unreliable, posing a risk of users accidentally opening it. Furthermore, since there is high voltage inside the cabinet body, using magnets to attract the cabinet body and the front cover does not comply with safety regulations.

[0004] Therefore, the display cabinet in the relevant technology cannot reliably connect the cabinet body and the front cover while also facilitating the maintenance of components. Summary of the Invention

[0005] The present invention provides a display screen enclosure and a display screen having the same, in order to solve the problem in the related art that the display screen enclosure cannot reliably connect the enclosure body and the front cover while also facilitating the maintenance of components.

[0006] According to one aspect of the present invention, a display screen enclosure is provided, the display screen enclosure comprising: an enclosure body having a component receiving cavity; a front cover including a first cover and a second cover that are closable and cover the opening of the component receiving cavity, the first cover and the second cover being arranged along the extending direction of the component receiving cavity, and the first cover being slidably disposed along the extending direction of the component receiving cavity; a positioning member including a fixing seat and a first positioning part disposed on the fixing seat, the fixing seat being located inside the component receiving cavity and connected to the enclosure body, the first cover being provided with a second positioning part, one of the first positioning part and the second positioning part being a positioning pin, ... The other part of the two positioning parts is a positioning hole. The extension direction of both the positioning pin and the positioning hole is the same as the extension direction of the component receiving cavity. When the first cover is closed on the component receiving cavity and the second cover is open, the first cover slides away from the second cover so that the positioning pin can be inserted into the positioning hole. The first cover slides towards the second cover so that the positioning pin can be dislodged from the positioning hole. When both the first cover and the second cover are closed on the component receiving cavity and the positioning pin is inserted into the positioning hole, the second cover is connected to the housing body. The second cover abuts against or is clearance-fitted with the first cover to restrict the sliding of the first cover.

[0007] Furthermore, a lateral adjustment structure is provided between the fixing base and the box body, and the fixing base can adjust its lateral position relative to the box body through the lateral adjustment structure.

[0008] Furthermore, the lateral adjustment structure includes a fixing screw and an adjustment hole. The adjustment hole is set vertically through the fixing seat. The fixing screw passes through the adjustment hole and is threadedly connected to the housing body. The fixing screw includes a screw rod and a screw head. The diameter of the adjustment hole is larger than the diameter of the screw rod and smaller than the diameter of the screw head.

[0009] Furthermore, a vertical adjustment structure is provided between the fixing base and the box body, and the vertical position of the fixing base relative to the box body can be adjusted through the vertical adjustment structure.

[0010] Furthermore, the vertical adjustment structure includes an adjusting screw and a screw hole. The screw hole is set vertically through the fixed base, the adjusting screw passes through the screw hole and is threadedly connected to the screw hole, and the end of the adjusting screw protrudes or is flush with the fixed base and abuts against the housing body.

[0011] Furthermore, the opening of the component receiving cavity has a first side and a second side in a direction perpendicular to the extension direction of the component receiving cavity, and the second cover is hinged to the box body at the part corresponding to the first side or the second side, and a locking structure is provided between the second cover and the box body.

[0012] Furthermore, the locking structure includes a connecting seat and a locking screw. The connecting seat is located on the side of the second cover facing the housing body. When the second cover is closed on the component receiving cavity, the connecting seat extends into the component receiving cavity, and the locking screw passes through the housing body and connects with the connecting seat.

[0013] Furthermore, the housing body is provided with a slide rail, and both the first cover and the second cover are provided with a sliding sleeve. The extension direction of the slide rail and the extension direction of the sliding sleeve are the same as the extension direction of the component receiving cavity. The slide rail passes through the sliding sleeve, and the sliding sleeve can rotate around the slide rail. The end wall of the second cover protrudes from the end wall of the sliding sleeve on the second cover to form a clearance notch between them. When the first cover slides toward the direction closer to the second cover, the clearance notch can avoid the sliding sleeve on the first cover.

[0014] Furthermore, the end of the cabinet body is provided with a side cover, and the display cabinet also includes a side cover. The side cover is detachably connected to the side of the cabinet body. When both the first cover and the second cover cover the component receiving cavity and the positioning pin is inserted into the positioning hole, the end of the first cover away from the second cover abuts or gap-fits with the side cover to restrict the sliding of the first cover.

[0015] Furthermore, the front cover includes two first cover bodies and one second cover body, with the two first cover bodies located at both ends of the second cover body. Each first cover body is provided with a positioning element, and the first positioning part is located on the side of the fixing seat facing the second cover body; and / or, the component receiving cavity is located at the bottom of the housing body, and the fixing seat is connected to the top wall of the component receiving cavity; and / or, the positioning element also includes a shock-absorbing pad, which is located on the side of the fixing seat facing the front cover.

[0016] Furthermore, the positioning element also includes a mounting fixture that is slidably disposed along the extension direction of the component receiving cavity, the cross-sectional shape of which is the same as that of the first cover.

[0017] Furthermore, the front cover also includes a shielding cover, which is disposed on the side of the second cover away from the main body of the housing. The shielding cover protrudes from the end of the second cover in the extension direction of the component receiving cavity. The end of the first cover facing the second cover is provided with a stepped structure. When both the first cover and the second cover are covered in the component receiving cavity and the positioning pin is inserted into the positioning hole, the end of the second cover abuts or is clearance-fitted with the end of the first cover, and the end of the shielding cover is embedded in the stepped structure.

[0018] According to another aspect of the present invention, a display screen is provided, the display screen comprising: a display unit; a display screen housing, the display unit being disposed on the housing body of the display screen housing, the display screen housing being the display screen housing provided above.

[0019] According to the technical solution of this invention, the display screen cabinet includes a cabinet body, a front cover, and a positioning component. When the first cover is closed onto the component receiving cavity, the positioning pin is coaxial with the positioning hole, and the positioning pin can be inserted into the positioning hole to connect the first positioning part and the second positioning part. During the insertion process, the first cover needs to slide away from the second cover along the extension direction of the component receiving cavity. Due to the limitation of the movement direction of the first cover, the positioning pin can only be inserted into the positioning hole when the first cover is closed and the second cover is open. After the positioning pin is inserted into the positioning hole, the second cover is closed onto the component receiving cavity. Since the first cover and the second cover are arranged along the extension direction of the component receiving cavity, the sliding of the first cover is restricted by the abutment or clearance fit between the second cover and the first cover, preventing the positioning pin from coming out of the positioning hole and ensuring a reliable connection between the front cover and the cabinet body. When repairing the component housing cavity, simply open the second cover and slide the first cover towards the second cover along the extension direction of the component housing cavity. This allows the locating pin to disengage from the locating hole, enabling the first cover to be opened and facilitating repair of the component housing cavity. Therefore, when the front cover of the display screen cabinet is connected to the cabinet body, the second cover restricts the sliding of the first cover. When repairing the component housing cavity, simply disconnect the second cover from the cabinet body to separate the front cover and the cabinet body. This ensures a reliable connection between the front cover and the cabinet body and facilitates repair of the component housing cavity. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 11 As shown, this embodiment of the invention provides a display screen enclosure, which includes an enclosure body 10, a front cover 20, and a positioning member 30. The enclosure body 10 has a component receiving cavity 11. The front cover 20 includes a first cover 21 and a second cover 22 that can be opened and closed to cover the opening of the component receiving cavity 11. The first cover 21 and the second cover 22 are arranged along the extending direction of the component receiving cavity 11, and the first cover 21 is slidably disposed along the extending direction of the component receiving cavity 11. The positioning member 30 includes a fixing seat 31 and a first positioning part 32 disposed on the fixing seat 31. The fixing seat 31 is located inside the component receiving cavity 11 and connected to the enclosure body 10. A second positioning part 211 is disposed on the first cover 21. One of the first positioning part 32 and the second positioning part 211 is a positioning pin 321. Another part of the positioning part 211 is the positioning hole 2111. The extension direction of both the positioning pin 321 and the positioning hole 2111 is the same as the extension direction of the component receiving cavity 11. When the first cover 21 is closed on the component receiving cavity 11 and the second cover 22 is open, the first cover 21 slides away from the second cover 22 so that the positioning pin 321 can be inserted into the positioning hole 2111. The first cover 21 slides towards the second cover 22 so that the positioning pin 321 can be dislodged from the positioning hole 2111. When both the first cover 21 and the second cover 22 are closed on the component receiving cavity 11 and the positioning pin 321 is inserted into the positioning hole 2111, the second cover 22 is connected to the housing body 10. The second cover 22 abuts against or is clearance-fitted with the first cover 21 to restrict the sliding of the first cover 21.

[0042] The display cabinet provided in this embodiment includes a cabinet body 10, a front cover 20, and a positioning member 30. When the first cover 21 is closed on the component receiving cavity 11, the positioning pin 321 is coaxial with the positioning hole 2111. The positioning pin 321 can be inserted into the positioning hole 2111 to connect the first positioning part 32 and the second positioning part 211. During the insertion process, the first cover 21 needs to be slid away from the second cover 22 along the extension direction of the component receiving cavity 11. Due to the limitation of the movement direction of the first cover 21, the positioning pin 321 can only be inserted into the positioning hole 2111 when the first cover 21 is closed and the second cover 22 is open. After the positioning pin 321 is inserted into the positioning hole 2111, the second cover 22 is placed over the component receiving cavity 11. Since the first cover 21 and the second cover 22 are arranged along the extension direction of the component receiving cavity 11, the sliding of the first cover 21 is restricted by the abutment or clearance fit between the second cover 22 and the first cover 21, preventing the positioning pin 321 from coming out of the positioning hole 2111, and ensuring a reliable connection between the front cover 20 and the housing body 10. When performing maintenance on the component receiving cavity 11, it is only necessary to open the second cover 22 and slide the first cover 21 along the extension direction of the component receiving cavity 11 towards the second cover 22, so that the positioning pin 321 comes out of the positioning hole 2111, thereby allowing the first cover 21 to be opened for convenient maintenance of the component receiving cavity 11. Therefore, when the front cover 20 of the display screen cabinet is connected to the cabinet body 10, the sliding of the first cover 21 is restricted by the second cover 22. When performing maintenance on the component receiving cavity 11, it is only necessary to disconnect the connection between the second cover 22 and the cabinet body 10 to separate the front cover 20 and the cabinet body 10. This makes the connection between the front cover 20 of the display screen cabinet and the cabinet body 10 reliable and facilitates maintenance on the component receiving cavity 11.

[0043] In this embodiment, the first positioning part 32 is a positioning pin 321, and the second positioning part 211 is a positioning hole 2111.

[0044] like Figure 5 As shown, a lateral adjustment structure 40 is provided between the fixing base 31 and the cabinet body 10. The fixing base 31 can adjust its lateral position relative to the cabinet body 10 through the lateral adjustment structure 40. By adjusting the lateral position of the fixing base 31 relative to the cabinet body 10 through the lateral adjustment structure 40, deformation errors of the cabinet body 10 or installation errors of the fixing base 31 on the cabinet body 10 can be eliminated. This ensures that when the first cover 21 is closed on the component receiving cavity 11, sliding the first cover 21 along the extension direction of the component receiving cavity 11 allows the positioning pin 321 to be inserted into the positioning hole 2111, connecting the first cover 21 and the cabinet body 10, thereby ensuring the reliability of the display cabinet.

[0045] like Figure 7As shown, the horizontal adjustment structure 40 includes a fixing screw 41 and an adjustment hole 42. The adjustment hole 42 is vertically inserted through the fixing seat 31. The fixing screw 41 passes through the adjustment hole 42 and is threadedly connected to the cabinet body 10. The fixing screw 41 includes a screw rod 411 and a screw head 412. The diameter of the adjustment hole 42 is larger than the diameter of the screw rod 411 and smaller than the diameter of the screw head 412. By fixing the screw 41 through the adjustment hole 42 and threadedly connected to the cabinet body 10, and because the diameter of the adjustment hole 42 is larger than the diameter of the screw rod 411 and smaller than the diameter of the screw head 412, the fixing seat 31 is moved laterally, causing the screw rod 411 to move laterally in the adjustment hole 42. This eliminates deformation errors of the cabinet body 10 or installation errors of the fixing seat 31 on the cabinet body 10, ensuring that when the first cover 21 is closed on the component receiving cavity 11, the positioning pin 321 can be inserted into the positioning hole 2111, thereby ensuring the reliability of the display cabinet.

[0046] The screw head of the fixing screw 41 abuts against the fixing seat 31, and the adjusting hole 42 is a smooth hole (a through hole with a smooth inner wall).

[0047] like Figure 5 As shown, a vertical adjustment structure 50 is also provided between the fixing base 31 and the cabinet body 10. The fixing base 31 can adjust its vertical position relative to the cabinet body 10 through the vertical adjustment structure 50. By adjusting the vertical position of the fixing base 31 relative to the cabinet body 10 through the vertical adjustment structure 50, the deformation error of the cabinet body 10 or the installation error of the fixing base 31 on the cabinet body 10 can be eliminated. This ensures that when the first cover 21 is closed on the component receiving cavity 11, the first cover 21 can slide along the extension direction of the component receiving cavity 11, so that the positioning pin 321 can be inserted into the positioning hole 2111, connecting the first cover 21 and the cabinet body 10, thereby ensuring the reliability of the display cabinet.

[0048] like Figure 7 As shown, the vertical adjustment structure 50 includes an adjusting screw 51 and a screw hole 52. The screw hole 52 is vertically inserted through the fixing base 31. The adjusting screw 51 passes through the screw hole 52 and is threadedly connected to the screw hole 52. The end of the adjusting screw 51 protrudes or is flush with the fixing base 31 and abuts against the cabinet body 10. Since the adjusting screw 51 passes through the screw hole 52 and abuts against the cabinet body 10, and the adjusting screw 51 is threadedly connected to the screw hole 52, by rotating the adjusting screw 51, the adjusting screw 51 drives the fixing base 31 to move up and down relative to the cabinet body 10 through the threaded connection, so as to eliminate the deformation error of the cabinet body 10 or the installation error of the fixing base 31 on the cabinet body 10, and ensure that when the first cover 21 is closed on the component receiving cavity 11, the positioning pin 321 can be inserted into the positioning hole 2111, thereby ensuring the reliability of the display cabinet.

[0049] It should be noted that the end of the adjusting screw 51 abuts against the housing body 10, meaning that the end of the adjusting screw 51 is not connected to the housing body 10.

[0050] like Figure 2 As shown, the opening of the component receiving cavity 11 has a first side and a second side in a direction perpendicular to the extension direction of the component receiving cavity 11. The second cover 22 is hinged to the housing body 10 at the part corresponding to the first side or the second side. A locking structure 60 is provided between the second cover 22 and the housing body 10. When the front cover 20 of the display screen housing is connected to the housing body 10, the second cover 22 is rotated upward so that the second cover 22 covers the component receiving cavity 11. The locking structure 60 connects the second cover 22 and the housing body 10, ensuring a reliable connection between the second cover 22 and the housing body 10. When performing maintenance on the component receiving cavity 11, the connection between the second cover 22 and the housing body 10 is disconnected by the locking structure 60, the second cover 22 is rotated downward, and the first cover 21 is slid along the extension direction of the component receiving cavity 11, so that the first cover 21 can be opened, facilitating maintenance on the component receiving cavity 11 from the front.

[0051] like Figure 2 As shown, the locking structure 60 includes a connecting seat 61 and a locking screw 62. The connecting seat 61 is located on the side of the second cover 22 facing the cabinet body 10. When the second cover 22 is closed on the component receiving cavity 11, the connecting seat 61 extends into the component receiving cavity 11, and the locking screw 62 passes through the cabinet body 10 and connects to the connecting seat 61. When the front cover 20 of the display cabinet is connected to the cabinet body 10, the second cover 22 is rotated upwards, causing the connecting seat 61 to extend into the component receiving cavity 11. The cabinet body 10 and the connecting seat 61 are connected from the outer bottom wall of the cabinet body 10 using the locking screw 62, thereby making the connection between the second cover 22 and the cabinet body 10 quick, reliable, and convenient.

[0052] like Figure 2 As shown, a slotted hole 14 is provided on the bottom wall of the cabinet body 10. The locking screw 62 passes through the slotted hole 14 and connects to the connecting seat 61. By using the slotted hole 14, the deformation error of the connecting seat 61 can be eliminated when the locking screw 62 connects the connecting seat 61 and the cabinet body 10. This ensures that when the second cover 22 is closed on the component receiving cavity 11, the locking screw 62 can pass through the cabinet body 10 and connect to the connecting seat 61, thereby ensuring the reliability of the display cabinet.

[0053] like Figure 2As shown, the housing body 10 is provided with a slide rail 12, and the first cover 21 and the second cover 22 are both provided with a sliding sleeve 23. The extension direction of the slide rail 12 and the extension direction of the sliding sleeve 23 are the same as the extension direction of the component receiving cavity 11. The slide rail 12 passes through the sliding sleeve 23, and the sliding sleeve 23 can rotate around the slide rail 12. The end wall of the second cover 22 protrudes from the end wall of the sliding sleeve 23 on the second cover 22 to form a clearance notch 221 between the two. When the first cover 21 slides toward the direction closer to the second cover 22, the clearance notch 221 can avoid the sliding sleeve 23 on the first cover 21. Since the slide rail 12 passes through the slide sleeve 23, and the extension directions of both the slide rail 12 and the slide sleeve 23 are the same as the extension direction of the component receiving cavity 11, the guide effect of the slide rail 12 on the slide sleeve 23 allows the first cover 21 and the second cover 22 to slide relative to the cabinet body 10 along the extension direction of the component receiving cavity 11. When the front cover 20 of the display cabinet is connected to the cabinet body 10, the first cover 21 slides along the extension direction of the component receiving cavity 11, so that the positioning pin 321 can be inserted into the positioning hole 2111. Thus, the guide effect of the slide rail 12 on the slide sleeve 23 ensures the reliability of the display cabinet.

[0054] Among them, such as Figure 2 As shown, when the front cover 20 of the display screen cabinet is connected to the cabinet body 10, the end wall of the second cover 22 restricts the sliding of the first cover 21, making the connection between the front cover 20 of the display screen cabinet and the cabinet body 10 reliable. When performing maintenance on the component receiving cavity 11, the connection between the second cover 22 and the cabinet body 10 is disconnected, and the second cover 22 is rotated downwards. Since the gap between the end wall of the second cover 22 and the end wall of the sliding sleeve 23 on the second cover 22 forms an avoidance notch 221, the first cover 21 can slide towards the second cover 22, thereby disengaging the positioning pin 321 from the positioning hole 2111. Rotating the first cover 21 downwards facilitates maintenance on the component receiving cavity 11.

[0055] In this embodiment, the slide rail 12 and the cabinet body 10 are integrally formed, which makes the connection between the cabinet body 10 and the slide rail 12 reliable, thereby reducing the processing difficulty of the display cabinet and ensuring the reliability of the display cabinet.

[0056] like Figure 1As shown, the display cabinet also includes a side cover 13, which is detachably connected to the side of the cabinet body 10. When the first cover 21 and the second cover 22 are both covered and fit into the component receiving cavity 11 and the positioning pin 321 is inserted into the positioning hole 2111, the end of the first cover 21 away from the second cover 22 abuts against or gap fits with the side cover 13 to restrict the sliding of the first cover 21. After the locking structure 60 connects the second cover 22 to the cabinet body 10, the side cover 13 is connected to the cabinet body 10. The side cover 13 restricts the sliding of the first cover 21. When performing maintenance on the component receiving cavity 11, the side cover 13 is removed from the cabinet body 10, and the connection between the second cover 22 and the cabinet body 10 is disconnected. The first cover 21 is slid along the extension direction of the component receiving cavity 11, so that the positioning pin 321 is dislodged from the positioning hole 2111, thereby allowing the first cover 21 to be opened, which facilitates maintenance on the component receiving cavity 11. Furthermore, the detachable connection between the side cover 13 and the cabinet body 10 makes the connection between the front cover 20 of the display cabinet and the cabinet body 10 reliable and facilitates maintenance on the component receiving cavity 11.

[0057] like Figure 1 and Figure 3 As shown, the front cover 20 includes two first cover bodies 21 and one second cover body 22. The two first cover bodies 21 are located at both ends of the second cover body 22. Each first cover body 21 is provided with a positioning member 30. The first positioning part 32 is located on the side of the fixing base 31 facing the second cover body 22. With the above structure, it is only necessary to open the first cover body 21 corresponding to the maintenance position to perform maintenance inside the component receiving cavity 11, which further facilitates the maintenance of the component receiving cavity 11. When the front cover 20 of the display screen cabinet is connected to the cabinet body 10, since the two first cover bodies 21 are located at both ends of the second cover body 22, the sliding of the two first cover bodies 21 can be restricted by one second cover body 22, so that the connection between the front cover 20 of the display screen cabinet and the cabinet body 10 is reliable. Furthermore, when the size of the front cover 20 is fixed, since the front cover 20 includes two first cover bodies 21, the size of each first cover body 21 in its extension direction is reduced, which facilitates the processing of the first cover body 21 and reduces the degree of deformation of the first cover body 21 during transportation, thereby reducing the processing difficulty of the first cover body 21 and ensuring the reliability of the display screen cabinet.

[0058] Furthermore, when the first cover 21 is closed on the component receiving cavity 11, since the first positioning part 32 is located on the side of the fixing base 31 facing the second cover 22, the first cover 21 is moved away from the second cover 22, so that the positioning pin 321 can pass through the positioning hole 2111. The first cover 21 is moved closer to the second cover 22, so that the positioning pin 321 can be dislodged from the positioning hole 2111. When the front cover 20 of the display cabinet is connected to the cabinet body 10, the end wall of the second cover 22 restricts the sliding of the first cover 21 towards the second cover 22, thereby preventing the positioning pin 321 from being dislodged from the positioning hole 2111, thus making the connection between the front cover 20 of the display cabinet and the cabinet body 10 reliable.

[0059] like Figure 3 As shown, the component receiving cavity 11 is located at the bottom of the cabinet body 10, and the fixing base 31 is connected to the top wall of the component receiving cavity 11. With this structure, since the component receiving cavity 11 is located at the lower end of the cabinet body 10, it is convenient to maintain the component receiving cavity 11. Furthermore, since the fixing base 31 is connected to the top wall of the component receiving cavity 11, when the front cover 20 of the display cabinet is connected to the cabinet body 10, the lower end of the first cover 21 is hinged to the cabinet body 10, and the upper end of the first cover 21 is connected to the fixing base 31. This ensures a reliable connection between the first cover 21 and the cabinet body 10, improving the safety of the display cabinet.

[0060] like Figure 3 As shown, the positioning component 30 also includes a shock-absorbing pad 34, which is disposed on the side of the fixing base 31 facing the front cover 20. When the front cover 20 of the display cabinet is connected to the cabinet body 10, the shock-absorbing pad 34 absorbs the back-and-forth swaying of the front cover 20 relative to the cabinet body 10, ensuring the connection stability between the front cover 20 and the cabinet body 10.

[0061] like Figure 4As shown, the positioning component 30 also includes a mounting fixture 33 slidably disposed along the extension direction of the component receiving cavity 11. The cross-sectional shape of the mounting fixture 33 is the same as that of the first cover 21. During the process of installing the fixing seat 31 onto the housing body 10, since the cross-sectional shape of the mounting fixture 33 is the same as that of the first cover 21, the mounting fixture 33 is also provided with positioning holes 2111. When there is an error in the installation position of the positioning pin 321, by installing the mounting fixture 33 onto the housing body 10, the mounting fixture 33 covers the component receiving cavity 11, and the position of the fixing seat 31 relative to the housing body 10 is adjusted by the horizontal adjustment structure 40 and the vertical adjustment structure 50, so that... The positioning pin 321 is moved to a position where its axis coincides with the axis of the positioning hole 2111. Then, the position of the fixing seat 31 is fixed, and the mounting fixture 33 is removed from the housing body 10. Thus, when the first cover 21 is closed on the component receiving cavity 11, the axis of the positioning pin 321 coincides with the axis of the positioning hole 2111. The first cover 21 is slid along the extension direction of the component receiving cavity 11, so that the positioning pin 321 can be inserted into the positioning hole 2111, thereby ensuring the reliability of the display screen housing.

[0062] In this embodiment, the mounting fixture 33 and the first cover 21 are made of the same profile to ensure that the cross-sectional shape of the mounting fixture 33 is the same as that of the first cover 21. Furthermore, in the extension direction of the component receiving cavity 11, the length of the mounting fixture 33 is less than the length of the first cover 21, which provides the advantage of convenient operation when adjusting the position of the positioning pin 321.

[0063] like Figure 11 As shown, the front cover 20 also includes a shielding cover 24, which is disposed on the side of the second cover 22 away from the housing body 10. The shielding cover 24 protrudes from the end of the second cover 22 in the extension direction of the component receiving cavity 11. The end of the first cover 21 facing the second cover 22 is provided with a stepped structure 212. When both the first cover 21 and the second cover 22 are covered in the component receiving cavity 11 and the positioning pin 321 is inserted in the positioning hole 2111, the end of the second cover 22 abuts or gap-fits with the end of the first cover 21, and the end of the shielding cover 24 is embedded in the stepped structure 212. When the front cover 20 of the display cabinet is connected to the cabinet body 10, since the first cover 21 has a stepped structure 212 at one end facing the second cover 22, and the end of the shielding cover 24 is embedded in the stepped structure 212, the shielding cover 24 can block the gap between the first cover 21 and the second cover 22 from the front of the display cabinet, preventing the user from contacting the high voltage in the component housing cavity 11 from the front of the front cover 20, thus improving the safety of the display cabinet.

[0064] It should be noted that the end of the cover 24 is embedded in the stepped structure 212, which means that the front surface of the cover 24 protrudes outward and is flush with the front surface of the first cover 21, and the front surface of the first cover 21 protrudes outward and is parallel to the rear surface of the cover 24.

[0065] like Figures 1 to 11 As shown, another embodiment of the present invention provides a display screen, which includes a display unit 71 and a display screen housing 72. The display unit 71 is disposed on the housing body 10 of the display screen housing 72, and the display screen housing 72 is the display screen housing provided above. Therefore, the display screen provided in this embodiment can also use the second cover 22 to restrict the sliding of the first cover 21, so that the connection between the front cover 20 of the display screen housing and the housing body 10 is reliable. Moreover, the front cover 20 and the housing body 10 can be separated simply by disconnecting the connection between the second cover 22 and the housing body 10, which facilitates the maintenance of the component receiving cavity 11.

[0066] The apparatus provided in this embodiment has the following beneficial effects:

[0067] (1) When the front cover 20 of the display cabinet is connected to the cabinet body 10, the sliding of the first cover 21 is restricted by the second cover 22. When the component receiving cavity 11 is repaired, it is only necessary to disconnect the connection between the second cover 22 and the cabinet body 10 to separate the front cover 20 and the cabinet body 10, so that the connection between the front cover 20 of the display cabinet and the cabinet body 10 is reliable and convenient for the component receiving cavity 11 to be repaired.

[0068] (2) During the process of installing the fixing seat 31 onto the housing body 10, since the cross-sectional shape of the mounting fixture 33 is the same as that of the first cover 21, the mounting fixture 33 is also provided with positioning holes 2111. When there is an error in the installation position of the positioning pin 321, the mounting fixture 33 is installed onto the housing body 10, so that the mounting fixture 33 covers the component receiving cavity 11. The position of the fixing seat 31 relative to the housing body 10 is adjusted by using the horizontal adjustment structure 40 and the vertical adjustment structure 50. Move the positioning pin 321 to a position where its axis coincides with the axis of the positioning hole 2111, then fix the position of the fixing seat 31, and remove the mounting fixture 33 from the cabinet body 10. Thus, when the first cover 21 is closed on the component receiving cavity 11, the axis of the positioning pin 321 coincides with the axis of the positioning hole 2111. Slide the first cover 21 along the extension direction of the component receiving cavity 11 so that the positioning pin 321 can be inserted into the positioning hole 2111, thereby ensuring the reliability of the display cabinet.

[0069] (3) When the front cover 20 of the display screen cabinet is connected to the cabinet body 10, rotate the second cover 22 upward so that the connecting seat 61 extends into the component receiving cavity 11. Use the locking screw 62 to connect the cabinet body 10 and the connecting seat 61 from the outer bottom wall of the cabinet body 10, so that the connection between the second cover 22 and the cabinet body 10 is fast, reliable and convenient.

[0070] (4) The shock-absorbing pad 34 is used to absorb the front cover 20’s back-and-forth sway relative to the box body 10, ensuring the connection stability between the front cover 20 and the box body 10.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
