Description

Technical Field

[0001] The utility model belongs to the technical field of inflatable cabinet structures, and in particular relates to an inflatable cabinet which is easy to maintain. Background Art

[0002] Inflatable cabinet is a kind of automatic distribution cabinet, and its outstanding feature is high-voltage gas insulation, which protects various switch devices. Generally, inflatable cabinets are often used in large indoor public places such as shopping malls, airports, and subway stations.

[0003] The common inflatable cabinets currently available mainly include: cabinet, integrated power switch, waterproof shell wiring, dynamic seal, explosion-proof valve, and other accessories. Among them, the cabinet is generally rectangular, and the front structure of the cabinet generally includes a button panel, a display panel, and an inspection door.

[0004] For example, the Chinese utility model patent with authorization announcement number CN220273155U and authorization announcement date 2023.12.29 discloses an environmentally friendly inflatable cabinet that is easy to maintain, including a cabinet body, the front of the cabinet body is provided with control buttons and a display screen, and the bottom of the cabinet body is fixed with four universal wheels arranged in a rectangular shape. The cabinet body is provided with a locking box, a pull rod, a locking block, a first spring, a limit groove, a second spring, an insertion rod, an inspection door, a card block, and a limit strip.

[0005] The principle of the inflatable cabinet in this utility model patent for its convenient maintenance feature is as follows: when the equipment needs to be repaired, first pull the two sets of pull rods away from the cabinet body, the pull rods then drive the locking block, and the locking block squeezes the first spring on one side. When the locking block is out of contact with the card block, multiple springs apply thrust to the insertion rod. Hold the two handles outside the inspection door and pull them outwards, then the inspection door can be removed and the original parts inside the equipment can be repaired.

[0006] However, in actual use, the inflatable cabinet still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] First, when the inspection door is opened, all four pull rods need to be pulled out. This process is relatively troublesome and needs to be operated in the upper left, lower left, upper right, and lower right positions in sequence. If the size of the inspection door is relatively large, the above troublesome characteristics are more prominent;

[0008] Second, after the universal wheel and the positioning structure are combined, the controllable movement of the inflatable cabinet is achieved, but there are problems of complex structure and complicated switching operations. The four positioning structures need to be fixed or released in turn, which is time-consuming and labor-intensive.

[0009] Therefore, in summary, there is an urgent need for an easy-to-maintain inflatable cabinet that has a simpler opening operation for the inspection door and a more convenient way of switching between the mobile and fixed states. Utility Model Content

DETAILED DESCRIPTION

[0036] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0037] As attached Figure 1-10 As shown, an inflatable cabinet that is easy to maintain has a structure including a rectangular cabinet 11, a button panel 12, and a display panel 13, and also includes a horizontal plate screw assembly unit 1 arranged on the inner side surface of the rectangular cabinet 11, a rod unit 2 arranged on the inner bottom surface of the rectangular cabinet 11, a sleeve door panel unit 3 arranged on the horizontal plate screw assembly unit 1 and the rod unit 2, and a roller unit 4 arranged on the outer side surface of the rectangular cabinet 11 and used to support the rectangular cabinet 11 when the rectangular cabinet 11 is tilted.

[0038] In this embodiment, the rectangular cabinet 11 has an opening on only one side, and the opening is installed in sequence from top to bottom: a button panel 12, a display panel 13, and a socket door panel unit 3, which, together with various existing structures necessary for the inflatable cabinet in the rectangular cabinet 11, ensures that the basic functions of the inflatable cabinet can be effectively performed.

[0039] Among them, the number of the sleeve door panel units 3 is 1-3, the upper part of which is screwed against the horizontal plate screw assembly unit 1 and the lower part of which is inserted into the insertion rod unit 2 after being pressed against each other, to ensure that it has sufficient and appropriate installation stability.

[0040] In addition, the disassembly and assembly operation of the sleeve door panel unit 3 includes a total of two steps, namely: rotating the cross plate screw assembly unit 1, and translating and placing the sleeve door panel unit 3, and the above-mentioned disassembly and assembly operation only needs one hand to complete, which is very simple and convenient, and meets the above-mentioned "easy to maintain" requirement.

[0041] In addition, the normal state of the rectangular cabinet 11 is vertically aligned, and the roller unit 4 is off the ground. When the inflatable cabinet needs to be moved, the rectangular cabinet 11 is first tilted, and then the roller unit 4 is supported on the ground, and then the rectangular cabinet 11 is lifted off the ground, and finally the inflatable cabinet can be pushed and rolled to be transported. This process is also simple and convenient. After the inflatable cabinet is moved to the desired position, it is rotated in the opposite direction to align the rectangular cabinet 11, and the entire transport operation can be completed.

[0042] It should be noted that in order to stably install the roller unit 4 and a large number of parts inside the inflatable cabinet, the five plates constituting the rectangular cabinet 11 are relatively thick plates with a thickness of 10-15 mm. The main body of the sleeve door panel unit 3 has a thickness of 4-8 mm and can be made of existing common thin steel plates.

[0043] The transverse plate screw assembly unit 1 includes a transverse plate 101 whose two ends are respectively arranged on two opposite inner sides of the rectangular cabinet 11, a screw 102 arranged on the transverse plate 101 and used to pass through the sleeve door panel unit 3, and a fastening nut 103 arranged on the screw 102 and used to engage the sleeve door panel unit 3.

[0044] In this embodiment, the outer side surface of the transverse plate 101 is the end point of the push-in installation action of the sleeve door panel unit 3 , and all the sleeve door panel units 3 are arranged on this transverse plate 101 .

[0045] The number and position of the screw rods 102 correspond to the number of the sleeve door panel units 3 and the position of the openings on each sleeve door panel unit 3. Finally, the sleeve door panel unit 3 is compressed by the fastening nut 103 to provide a sufficient sealing degree for the rectangular cabinet 11.

[0046] The rod insertion unit 2 includes a protruding block 201 disposed on the inner bottom surface of the rectangular cabinet 11 and used to block the sleeve door panel unit 3, and a cross bar 202 disposed on the protruding block 201 and used to pass through the sleeve door panel unit 3.

[0047] In this embodiment, each of the sleeve door panel units 3 corresponds to one of the screw rods 102 and 1-2 of the cross rods 202, so as to ensure that the sleeve door panel unit 3 has sufficient installation stability and an appropriate degree of complexity in assembly and disassembly.

[0048] The outer side surface of the protruding block 201 is flush with the outer side surface of the horizontal plate 101, so that when the sleeve door panel unit 3 is correctly installed, it is vertical, and its disassembly and assembly operation only requires horizontal movement.

[0049] Finally, the protruding block 201 and the cross bar 202 are integrally formed, and the protruding block 201 is either welded or screwed to the inner bottom surface of the rectangular cabinet 11, and the cross bar 202 is a simple round bar, and no thread is required to be set on it.

[0050] The sleeve door panel unit 3 includes a rectangular plate body 301, an upper hole 302 arranged on the rectangular plate body 301 and used to pass the screw rod 102, a lower hole 303 arranged on the rectangular plate body 301 and used to pass the cross bar 202, and a gripping block 304 arranged on the outer side of the rectangular plate body 301.

[0051] In this embodiment, the gripping block 304 is in the shape of a cuboid, and when gripped, it is convenient to take and place the rectangular plate 301 .

[0052] The sleeve door panel unit 3 further includes a holding slot 305 disposed on the upper surface of the holding block 304 and used for receiving the screwed-out fastening nut 103 .

[0053] In this embodiment, the gripping slot 305 has at least the following two functions:

[0054] First, as the four-finger insertion position for the holding action, the rectangular plate 301 is held more firmly and is not easy to fall;

[0055] Second, it serves as a drop receiving position after the fastening nut 103 is screwed out, so that it is not easily lost.

[0056] When the rectangular plate 301 is reinstalled, the fastening nut 103 is generally in the holding slot 305, and there is no need to search everywhere, which also makes the inflatable cabinet easy to maintain.

[0057] The roller unit 4 includes a protruding hole plate 401 arranged on the outer side of the rectangular cabinet 11, a roller shaft 402 arranged on the protruding hole plate 401, and a roller body 403 arranged on the roller shaft 402 and used to support the rectangular cabinet 11 when the rectangular cabinet 11 is tilted.

[0058] In this embodiment, the rolling transportation method of the inflatable cabinet is: the roller body 403 rotates on the fixed roller shaft 402, or the roller shaft 402 and the roller body 403 are an integral whole, and the roller shaft 402 can rotate on the opening of the protruding hole plate 401.

[0059] When the rectangular cabinet 11 is placed vertically and operates normally, the distance between the lower end of the roller body 403 and the ground a is 2-3 cm. When the rectangular cabinet 11 rotates 5-15°, it can be completely off the ground, and the roller body 403 can support and carry the rectangular cabinet 11 for rolling and transportation.

[0060] The roller unit 4 further includes an inclined plate 404 which is arranged on the protruding hole plate 401 and is used to connect the outer side surface of the rectangular cabinet 11 .

[0061] In this embodiment, the number of the protruding hole plates 401 is two, which are respectively located on both sides of the roller body 403 to improve the installation stability of the roller body 403 .

[0062] The number of the inclined plates 404 is 4, which are arranged in pairs, namely: a horizontal inclined plate group and a vertical inclined plate group. One end of the former is arranged on the relatively outer side surface of the protruding hole plate 401, and the other end is arranged on the bottom plate or the back plate of the rectangular cabinet 11.

[0063] One end of the latter is arranged on the upper surface of the protruding hole plate 401, and the other end is arranged on the bottom plate or the back plate of the rectangular cabinet 11, so as to further reinforce and install the roller body 403.

[0064] The transverse plate screw assembly unit 1 further includes bolts 104 disposed on the transverse plate 101 and used for mounting the display panel 13 .

[0065] In this embodiment, the height of the bolt 104 is higher than that of the screw rod 102 , so that the transverse plate 101 can be used not only for installing the sleeve door panel unit 3 , but also for installing the display panel 13 .

[0066] There are openings on the display panel 13 near the bottom edge, the positions and numbers of which are aligned with the bolts 104 .

[0067] A reinforcement strip 5 for mounting the button panel 12 and the display panel 13 is also provided on the inner side of the rectangular cabinet 11 .

[0068] In this embodiment, the function of the reinforcement strip 5 is similar to that of the transverse plate 101 , and the former has three functions: installing the button panel 12 , installing the display panel 13 , and reinforcing the rectangular cabinet 11 .

[0069] A U-shaped handle 6 is also provided on the outer side of the rectangular cabinet 11 for triggering the rolling support effect of the roller unit 4 by tilting the rectangular cabinet 11 .

[0070] In this embodiment, the U-shaped handle 6 is disposed on the side panel and / or the back panel of the rectangular cabinet 11, so that the rotation and small-range laying down action and the rotation and straightening action of the rectangular cabinet 11 are relatively convenient and safe.

[0071] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
