[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the cabinet after installation, wherein the front of the cabinet represents "front", the back represents "rear", the top represents "up", and the bottom represents "down". "Inside" refers to the side facing the inside of the cabinet in the left-right direction, and "outside" refers to the side facing the outside of the cabinet in the left-right direction.

[0035] In addition, the front-to-back direction defined in the embodiments of the present invention refers to the spacing direction between the front and back of the cabinet, the left-to-right direction defined refers to the spacing direction between the two sides of the cabinet, and the up-and-down direction defined refers to the spacing direction between the top and bottom of the cabinet.

[0036] Please also read Figure 1 and Figure 3 , the cabinet door panel installation structure provided by the utility model is now described. The cabinet door panel installation structure includes a top fixing member 1 connected between the top of the cabinet frame 3 and the top surface of the cabinet door panel 4; the top fixing member 1 includes a first fixing portion 11, a second fixing portion 12 and an upper limit block 13. The first fixing portion 11 is connected to the top of the frame 3; the second fixing portion 12 is connected to the first fixing portion 11 and extends above the door panel 4; the second fixing portion 12 is connected to the door panel 4 in a rotational manner in the up and down directions; the upper limit block 13 is connected to the first fixing portion 11 and / or the second fixing portion 12 and extends downward; the upper limit block 13 is located between the front end surface of the frame 3 and the door panel 4.

[0037] The cabinet body of the cabinet generally includes a frame 3, a door panel 4 installed in front of the frame 3, and sealing panels (including two side sealing panels, a back sealing panel, a top sealing panel and a bottom sealing panel) blocking the other surfaces of the frame 3. The frame 3 is generally a hexahedral structure, which is formed by splicing multiple cross beams, multiple longitudinal beams and multiple vertical beams. The door panel installation structure provided by the utility model is used to connect the door panel 4 and the frame 3, and can also ensure the normal rotation of the door panel 4.

[0038] Specifically, the first fixing part 11 is fixedly arranged on the top outer edge of the frame 3, and the second fixing part 12 is provided with a rotating shaft, which is inserted into the top outer edge of the door panel 4 and is rotatably connected to the door panel 4. It should be noted that in order to ensure the normal opening and closing of the door panel 4, there is a rotation gap between the outer end of the door panel 4 and the front end surface of the frame 3. The upper limit block 13 is located in the above-mentioned rotation gap, so it does not affect the normal installation of the top fixing member 1 and the door panel 4.

[0039] During the production and assembly process of the cabinet, the door panel 4 needs to be opened, that is, the opening angle of the door panel 4 reaches 180°, so that the relevant electrical equipment can be installed or removed from the cabinet. Since the door panel 4 and the frame 3 are connected through the above-mentioned top fixing part 1, there is no corresponding angle positioning structure, resulting in an uncertain opening angle of the door panel 4. If the artificial door opening force is large, causing the door panel 4 to rotate too much and exceed 180°, the door panel 4 will first touch the upper limit block 13. The upper limit block 13 can prevent the door panel 4 from continuing to rotate, thereby avoiding the door panel 4 from colliding with the front end surface and side sealing plate of the frame 3.

[0040] In addition, during normal maintenance operations of the cabinet, the opening angle of the door panel 4 does not need to be too large. It should be noted that when the door panel 4 is normally opened no more than 180°, it will not touch the upper limit block 13. When the door panel 4 is closed, the upper limit block 13 is located on the outside of the door panel 4, and the door panel 4 will not contact the upper limit block 13.

[0041] It should be noted that when the door panel 4 is in a closed state, the distance from the upper limit block 13 to the back of the door panel 4 is greater than the distance from the outer edge of the door panel 4 to the rotating shaft, so as to avoid the upper limit block 13 interfering with the normal opening of the door panel 4.

[0042] Compared with the prior art, the cabinet door panel installation structure provided by the utility model has a top fixing member 1 used to rotatably connect the door panel 4 to the front of the frame 3, and the top fixing member 1 has an upper limit block 13, and the upper limit block 13 is located between the front end face of the frame 3 and the door panel 4; when there is an uncontrollable external force that causes the opening angle of the door panel 4 to be too large, exceeding 180°, the door panel 4 will first touch the upper limit block 13, and the upper limit block 13 is used to limit the door panel 4 from continuing to rotate, so as to avoid the door panel 4 from colliding with the front end face of the frame 3 and the side sealing plate, thereby avoiding scratches and paint loss on the door panel 4 and the side sealing plate, thereby ensuring the overall aesthetic performance of the cabinet.

[0043] In some embodiments, the top fixing member 1 can be used as follows Figure 1 For installation locations shown, see Figure 1 The top fixing member 1 is an integrated plate-shaped structure; the first fixing portion 11 is arranged on the top surface of the frame 3 .

[0044] The first fixing portion 11 is fixedly arranged on the outer edge of the top surface of the frame 3, and the second fixing portion 12 is rotatably connected to the outer edge of the top surface of the door panel 4. It can be understood that the top surface of the first fixing portion 11 is coplanar with the top surface of the second fixing portion 12, and the bottom surface of the first fixing portion 11 is coplanar with the bottom surface of the second fixing portion 12. That is to say, there is no step structure between the first fixing portion 11 and the second fixing portion 12, so that the top fixing component 1 of the integrated plate-like structure is easy to design and manufacture, and easy to assemble with the frame 3.

[0045] See also Figure 1 and Figure 3 On the basis of the above embodiment, a mounting hole is provided on the top surface of the frame 3; a waist-shaped hole 111 is provided on the first fixing portion 11, the length direction of the waist-shaped hole 111 is the left-right direction, and the waist-shaped hole 111 corresponds to the mounting hole up and down; the first fixing portion 11 is fixed to the frame 3 by the fastener 5 passing through the waist-shaped hole 111 and the mounting hole in sequence.

[0046] Specifically, the horizontal beams, vertical beams and longitudinal beams of the frame 3 are all C-shaped steels, each of which is provided with a plurality of mounting holes, which are spaced apart along the length direction of each beam and are circular holes. Providing a plurality of mounting holes facilitates the assembly of other components on each beam and can also reduce the overall weight of the frame 3.

[0047] The first fixing portion 11 is fixed to the upper beam of the frame 3 , the waist-shaped hole 111 corresponds to the mounting hole at the outer edge of the top surface of the upper beam, and the first fixing portion 11 is fixed to the upper beam by the fastener 5 .

[0048] If the door panel 4 is offset in the left-right direction after installation, the fastener 5 can be loosened to fine-tune the position of the top fixing member 1 in the left-right direction to drive the door panel 4 to move slightly, so as to adjust the offset door panel 4 back to its original position.

[0049] Specifically, since the waist-shaped hole 111 is opened on the first fixing part 11, the hole diameter of the waist-shaped hole 111 in the left and right direction is larger than the hole diameter of the mounting hole. Even if the position of the first fixing part 11 is slightly adjusted, the waist-shaped hole 111 can be partially made to correspond to the mounting hole, which will not affect the fixation of the first fixing part 11.

[0050] In some embodiments, the thickness of the first fixing portion 11 in the up-down direction gradually decreases from inside to outside.

[0051] For some cabinets, since the electronic equipment inside is heavy and the electronic equipment is set on the frame 3, there is a problem of deformation of the frame 3. If the frame 3 is slightly deflected in the left and right direction, the door panel 4 will also be slightly deflected. If more than two door panels 4 are installed on some cabinets, among the multiple door panels 4, if at least one door panel 4 is slightly deflected, there will be a problem of height difference between the multiple door panels 4, affecting the overall aesthetic performance of the cabinet.

[0052] In order to solve the above problem, in this embodiment, the thickness of the first fixing part 11 is gradually reduced from the inside to the outside. It can be considered that the first fixing part 11 is a wedge-shaped plate with a gradually changing thickness, and in the left-right direction, the thickness of the outer side of the wedge-shaped plate is less than the thickness of the inner side. If the frame 3 is deformed to deflect to the right, the door panel 4 will deflect slightly to the right. Since the outer edge of the top surface of the door panel 4 is connected to the outer edge of the top surface of the frame 3, the top surface of the door panel 4 is higher on the left and lower on the right, and the top fixing member 1 needs to be slightly adjusted to the left. After the top fixing member 1 is adjusted to the left, the fixing height of the first fixing part 11 changes, which correspondingly raises the right end of the top surface of the door panel 4 and lowers the left end of the top surface of the door panel 4 to ensure that the top surface of the door panel 4 is level.

[0053] If the frame 3 is deformed to the left, the door panel 4 will deflect slightly to the left. Since the outer edge of the top surface of the door panel 4 is connected to the outer edge of the top surface of the frame 3, the top surface of the door panel 4 is lower on the left and higher on the right. It is necessary to move the top fixing member 1 to the right. After the top fixing member 1 is adjusted to the right, the fixing height of the first fixing part 11 changes, which correspondingly raises the left end of the top surface of the door panel 4 and lowers the right end of the top surface of the door panel 4 to ensure that the top surface of the door panel 4 is level.

[0054] Regardless of whether the door panel 4 deflects to the left or to the right, the offset of the door panel 4 can be changed by fine-tuning the fixing position of the top fixing member 1, thereby ensuring that the top surface heights of multiple door panels 4 are basically consistent and solving the problem of height difference.

[0055] In some embodiments, the frame 3 and the first fixing portion 11 may also be connected by Figure 1 The structure shown, see Figure 1 The top surface of the frame 3 is provided with a gasket 14, and the first fixing part 11 is arranged on the gasket 14. The gasket 14 plays the role of buffering and reducing vibration, increasing friction, avoiding hard contact between the first fixing part 11 and the frame 3, thereby increasing the fixing strength of the first fixing part 11.

[0056] In some embodiments, an elastic layer is connected to the outer surface of the upper limit block 13. The elastic layer can be bonded to the upper limit block 13, especially to the front end surface of the upper limit block 13, such as an adhesive tape; the elastic layer can also be wrapped around the upper limit block 13, such as an elastic rope with elasticity. The elastic layer plays a role in buffering and vibration reduction, avoiding hard contact between the door panel 4 and the upper limit block 13, thereby further reducing collision and scratching of the door panel 4.

[0057] In some embodiments, the cabinet door panel installation structure can also be used as follows: Figure 2 and Figure 4 The structure shown, see Figure 2 and Figure 4 The cabinet door panel mounting structure also includes a bottom fixing member 2 connected between the bottom of the frame 3 and the bottom surface of the door panel 4; the bottom fixing member 2 includes a third fixing portion 21 and a fourth fixing portion 22. The third fixing portion 21 is connected to the bottom of the frame 3; the fourth fixing portion 22 is connected to the third fixing portion 21 and extends below the door panel 4; the fourth fixing portion 22 is connected to the door panel 4 in a rotational manner in the up-down direction; the lower limit block 23 is connected to the third fixing portion 21 and / or the fourth fixing portion 22 and extends upward; the lower limit block 23 is located between the front end surface of the frame 3 and the door panel 4.

[0058] The bottom fixing member 2 also serves to connect the door panel 4 and the frame 3, and can also support the door panel 4, further increasing the connection strength between the door panel 4 and the frame 3, and preventing the door panel 4 from falling.

[0059] Specifically, the third fixing part 21 is fixedly arranged on the bottom outer edge of the frame 3, and the fourth fixing part 22 is provided with a rotating shaft, which is inserted into the bottom outer edge of the door panel 4 and is rotatably connected to the door panel 4. The lower limit block 23 is also located in the rotation gap.

[0060] The structural position of the lower limit block 23 is similar to that of the upper limit block 13, and the function of the lower limit block 23 is the same as that of the upper limit block 13. If the manual door opening force is large, causing the door panel 4 to rotate too much and exceed 180°, the door panel 4 will also touch the lower limit block 23, and the lower limit block 23 can also prevent the door panel 4 from continuing to rotate backward, thereby preventing the door panel 4 from colliding with the front end surface and side sealing plate of the frame 3.

[0061] When the door panel 4 is normally opened within 180°, it will not touch the lower stop block 23. When the door panel 4 is closed, the lower stop block 23 is located on the outside of the door panel 4, and the door panel 4 will not contact the lower stop block 23. Moreover, when the door panel 4 is in the closed state, the distance from the lower stop block 23 to the back of the door panel 4 is greater than the distance from the outer edge of the door panel 4 to the rotating shaft, so as to avoid the lower stop block 23 interfering with the normal opening of the door panel 4.

[0062] In some embodiments, the bottom fixing member 2 can be used as follows Figure 2 For installation locations shown, see Figure 2 , the bottom fixing member 2 is an integrated plate-like structure; the third fixing portion 21 is arranged on the bottom front end surface of the frame 3, and the fourth fixing portion 22 is connected to the bottom surface of the door panel 4, so the bottom fixing member 2 is a bent plate-like structure.

[0063] The third fixing portion 21 is arranged on the bottom front end surface of the frame 3 through the fastener 5 to facilitate the assembly of the bottom fixing member 2; in addition, the third fixing portion 21 is located on the bottom front end surface of the frame 3. On the one hand, it can avoid the vertical beams of the frame 3 so that the lower ends of the vertical beams of the frame 3 can form lower legs to support the ground; on the other hand, it can also avoid the reinforcing structure at the bottom of the frame 3.

[0064] In some embodiments, an elastic layer is connected to the outer surface of the lower limit block 23. The elastic layer can be bonded to the lower limit block 23, especially to the front end surface of the lower limit block 23, such as the elastic layer is an adhesive tape; the elastic layer can also be wrapped around the lower limit block 23, such as the elastic layer is an elastic rope with elasticity. The elastic layer plays a role in buffering and vibration reduction, avoiding hard contact between the door panel 4 and the lower limit block 23, thereby further reducing collision and scratching of the door panel 4.

[0065] Based on the same inventive concept, an embodiment of the present application further provides a cabinet, comprising a frame 3, a door panel 4 located in front of the frame 3, and the above-mentioned cabinet door panel installation structure.
