Description

Technical Field

[0001] This invention relates to the field of screen cabinet installation technology, specifically to a screen cabinet installation device and installation method. Background Technology

[0002] An electrical control cabinet is a cabinet used to install an electrical control system. When upgrading or replacing an electrical control cabinet, moving it presents certain difficulties. The installation location is usually in a confined space, making it inconvenient to move it directly by hoisting. The current practice is to first move the cabinet out of the confined space by hand before hoisting it to the designated location for the upgrade, replacement, and disassembly work. Because the cabinet is heavy, it requires a lot of manpower to move, which is time-consuming and labor-intensive.

[0003] In existing technologies, telescopic rollers are used for handling heavier cabinets. When the cabinet needs to be moved, the telescopic rollers extend from the bottom of the cabinet, and movement is achieved by the rollers, such as CN121035794A - An energy storage cabinet installation structure and its installation method; to facilitate the movement of the energy storage cabinet, the sliding wheels are inserted into or extended from the protective shell by controlling the telescopic mechanism's telescopic connection structure. However, this structure has technical problems: 1) Each sliding wheel is controlled by a telescopic mechanism. If multiple sliding wheels cannot touch the ground at the same time, the sliding wheel that touches the ground first will bear a large load, which may lead to structural failure or tilting. 2) It uses a linkage structure to adjust the sliding wheel to extend into or out of the protective shell. When the sliding wheel extends out of the protective shell and moves, the linkage structure plays a supporting role. When this structure is used in electrical cabinets with large weight, there is a problem with the support stability during the movement.

[0004] Therefore, it is necessary to design an installation device suitable for moving electrical cabinets. Summary of the Invention

[0005] The purpose of this invention is to provide a screen cabinet installation device and installation method, which not only enables the screen cabinet to be moved by rollers, but also ensures good stability during the movement.

[0006] This invention is achieved through the following technical solution: A cabinet installation device includes a cabinet body, with supporting legs at the bottom of the cabinet body, and further includes: A movable component is located at the bottom of the cabinet. The movable component includes a rotating shaft, a linear displacement mechanism, a first sliding component, and a motor. A linear displacement mechanism is provided at each end of the rotating shaft, and the motor is used to drive the rotating shaft to rotate. A first sliding component is provided on each side of the linear displacement mechanism, and the first sliding component is movably connected to the bottom of the cabinet. The linear displacement mechanism includes a fixed plate and a second sleeve. The fixed plate has two symmetrically arranged sliding grooves. A rotating shaft passes through the fixed plate, and the second sleeve is sleeved on the rotating shaft. Two connecting plates are symmetrically arranged on the same end of the second sleeve. One connecting plate is connected to the first slider via a first connecting rod, and the other connecting plate is connected to the second slider via a second connecting rod. The first and second sliders are slidably disposed in the sliding grooves and located on both sides of the second sleeve. The first and second sliders are respectively hinged to two first sliding components. A support assembly is provided on the outer wall of the cabinet. The support assembly includes a support rod, and a second sliding assembly is provided at the end of the support rod away from the cabinet. The support rod rotates to make the second sliding assembly slide in contact with the ground when the cabinet is moved.

[0007] Although the movable component of the present invention also achieves cabinet support by means of the support feet or by means of the first sliding component extending into or out of the bottom of the cabinet, so that the cabinet is in a fixed state (use state) or a movable state, the way the first sliding component extends into or out of the bottom of the cabinet in the present invention is different from the prior art: The first sliding component of this invention utilizes a designed linear displacement mechanism to extend into and out of the bottom of the cabinet. This linear displacement mechanism, driven by a motor, rotates a shaft to achieve horizontal linear displacement of the first and second sliders. This horizontal linear displacement is converted into rotational power for the first sliding component. The rotation of the first sliding component allows it to extend into and out of the cabinet. Specifically, when the first sliding component is in a tilted position during rotation, its bottom is higher than the bottom of the supporting foot. Therefore, the first sliding component is not in contact with the ground, and the cabinet is supported by the supporting foot. When the first sliding component is in a vertical position during rotation, its bottom is lower than the bottom of the supporting foot. In this position, the first sliding component is in contact with the ground, supporting the cabinet. Furthermore, the first sliding component can slide on the ground. Therefore, the cabinet can be moved out of the confined space of the installation location by sliding, saving manpower and improving operational convenience.

[0008] The first sliding component of the present invention rotates to extend into and out of the bottom of the cabinet, which is more stable than the existing technology that uses a linkage structure to achieve vertical extension and retraction during movement.

[0009] Furthermore, the present invention can achieve synchronous rotation of the four first sliding components by operating a single pivot, enabling the four first sliding components to land synchronously, thus further improving stability.

[0010] Meanwhile, in order to further improve the stability of the cabinet during movement, the present invention provides a support component on the outer wall of the cabinet. When the cabinet is needed, the support rod can be rotated so that the second sliding component slides in contact with the ground. The second sliding component can slide on the ground without affecting the movement of the cabinet. Moreover, the support rod is inclined and forms a triangular stable structure with the cabinet, which can further improve the stability of the cabinet during movement.

[0011] In summary, this invention not only enables the movement of the screen cabinet using rollers, but also ensures good stability during the movement process.

[0012] In a preferred embodiment, a fixed shaft is provided at the bottom of the cabinet; the first sliding assembly includes a first roller, a first bracket, a first support plate, and a third sleeve, one end of the first support plate is connected to the first bracket, and the other end is connected to the third sleeve, the third sleeve is rotatably disposed on the outer wall of the fixed shaft, and the first roller is mounted on the first bracket; the first slider and the second slider are respectively hinged to the first support plate; or the first slider and the second slider are respectively hinged to the first support plate through a connecting rod.

[0013] The first sliding component of the above-described structure of the present invention can effectively achieve rotation by utilizing horizontal force, thereby extending into or out of the bottom of the cabinet.

[0014] In a preferred embodiment, the support assembly further includes a positioning shaft, which is fixed to the outer wall of the cabinet by a fastener. One end of the support rod is fixedly or rotatably connected to the positioning shaft, and the second sliding assembly slides into contact with the ground by rotating the positioning shaft or rotating the support rod.

[0015] The support components of the above structure enable the support rod to be rotated to a specified position.

[0016] In a preferred embodiment, the positioning shaft is rotatably mounted within a fixed component. When the positioning shaft rotates to a designated position, it is fixed by a locking mechanism, which employs a pin and a socket combination structure.

[0017] If multiple support rods are provided on the positioning shaft, the synchronous rotation of the multiple support rods can be achieved by rotating the positioning shaft.

[0018] In a preferred embodiment, the positioning shaft is fixedly connected to the fixing member; one end of the support rod is rotatably mounted on the outer wall of the positioning shaft via a first sleeve, and the positioning shaft is provided with a locking member for limiting the circumferential displacement of the first sleeve; the locking member includes a positioning cylinder, one end of which is sleeved on the outer wall of the positioning shaft, and the other end is placed outside the first sleeve; the positioning cylinder and the first sleeve are locked by a pin and hole cooperation structure, or a positioning groove is provided on the outer wall of the first sleeve, and a circumferential limiting block is rotatably mounted on the side wall of the positioning cylinder. The circumferential limiting block has an eccentric structure, and the circumferential limiting block is pressed or released at the positioning groove on the outer wall of the first sleeve by rotating the circumferential limiting block.

[0019] The above structure enables the support rod to rotate independently, and the circumferential limiting block with an eccentric structure can press or send the first sleeve, which can improve the convenience of rotating the support rod to the designated position.

[0020] In a preferred embodiment, the positioning groove is an annular groove, and multiple circumferential limiting blocks are arranged along the circumference of the positioning groove.

[0021] By using multiple circumferential limiting blocks to simultaneously clamp the first sleeve, the stability of the first sleeve can be improved, and its circumferential positioning can be better limited.

[0022] In a preferred embodiment, the axial section of the positioning groove is viewed as a circular arc groove, and the outer wall of the circumferential limiting block is a curved surface structure to facilitate the rotation of the circumferential limiting block.

[0023] In a preferred embodiment, the side wall of the positioning cylinder is provided with a limiting shaft, and a circumferential limiting block is provided on the limiting shaft; an axial limiting block is also provided on the limiting shaft, the outer wall of the axial limiting block is placed in the positioning groove and does not squeeze the first sleeve, and the axial limiting block is used to limit the relative axial displacement of the positioning cylinder and the first sleeve.

[0024] The present invention, through the setting of axial limiting blocks and circumferential limiting blocks, can not only fix or loosen the first sleeve, but also ensure the relative axial position relationship between the positioning cylinder and the first sleeve, thus preventing the first sleeve from detaching from the positioning cylinder and causing the locking component to fail to lock the first sleeve.

[0025] In a preferred embodiment, the bottom of the cabinet is recessed upward to form a first groove and a second groove. The first groove is provided on both sides of the second groove. The first groove and the second groove are connected. The rotating shaft and the motor are installed in the second groove. The first sliding component and the linear displacement mechanism are installed in the first groove.

[0026] In a preferred embodiment, the support rod is a telescopic rod. The telescopic rod better accommodates angle adjustments, allowing the support rod to be adjusted to any angle before its extension or retraction ensures that the second sliding component at the end of the support rod makes sliding contact with the ground.

[0027] In a preferred embodiment, a gear is provided on the outer wall of the shaft, and the shaft is connected to the power output shaft of the motor via the gear.

[0028] In a preferred embodiment, the cabinet is provided with supporting components on the symmetrical sidewalls on both sides of the cabinet door; or the cabinet is provided with supporting components on the symmetrical sidewalls on both sides of the cabinet door and the sidewall opposite to the cabinet door.

[0029] An installation method for a screen cabinet installation device includes the following steps: S1. When the cabinet needs to be moved, the motor rotates the shaft, causing the first slider and the second slider to move in opposite directions, pushing the first sliding component to rotate, so that the first sliding component rotates from an inclined state to a vertical state. When the first sliding component rotates to the vertical state, the first sliding component rolls into contact with the ground. S2. Rotate the support rod until the second sliding component makes sliding contact with the ground.

[0030] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention improves the stability of cabinet movement by setting a moving component and a supporting component at the bottom and body of the cabinet, respectively. When the cabinet is moved, the first sliding component at the bottom of the moving component extends to facilitate movement, and the support rod of the supporting component opens to prevent the cabinet from tipping over during movement. Furthermore, the extension and retraction of the first sliding component is achieved by rotating a shaft, which causes the first and second sliders in the linear displacement mechanism to move horizontally. This horizontal linear displacement of the first and second sliders is converted into rotational power for the first sliding component. The rotation of the first sliding component enables it to extend and retract from the bottom of the cabinet, resulting in better support stability. It also enables simultaneous control of four first sliding components, ensuring that all four components land synchronously, avoiding tilting caused by the inability of the four components to land synchronously due to individual control.

[0034] In the following description, numerous specific details are set forth to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to practice the invention. In other embodiments, well-known structures, materials, or methods are not specifically described to avoid obscuring the invention. Unless otherwise specified, the materials, instruments, and reagents used in the following embodiments are commercially available. Unless otherwise specified, the techniques used in the embodiments are conventional methods well known to those skilled in the art.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] Example 1: like Figures 1-11 As shown, a cabinet installation device includes a cabinet body 1, which is equipped with a cabinet door. The cabinet body 1 adopts a conventional square structure, and the bottom of the cabinet body 1 is provided with support feet 11. On the one hand, the support feet 11 support the cabinet body 1 to prevent the bottom of the cabinet body from directly contacting the ground, thereby reducing the impact of ground moisture on the electronic components inside the cabinet. On the other hand, in this embodiment, it provides space for the insertion and extension of the first sliding component 22. In order to facilitate the movement of the cabinet body 1 and ensure the stability of the cabinet body 1 during the movement, the cabinet installation device further includes: The movable component 2 is used to move the cabinet by means of rollers, so as not to affect the stable placement of the cabinet on the ground during normal operation. The moving component 2 is located at the bottom of the cabinet 1. The moving component 2 includes a rotating shaft 23, a linear displacement mechanism 21, a first sliding component 22, and a motor. A linear displacement mechanism 21 is provided at each end of the rotating shaft 23. The motor is used to drive the rotating shaft 23 to rotate. In one specific embodiment, a gear 24 can be provided on the outer wall of the rotating shaft 23, and the power output shaft of the motor is provided with a drive gear that meshes with the gear 24 to realize the rotation of the rotating shaft 23 by the motor. A first sliding component 22 is provided on each side of the linear displacement mechanism 21. The first sliding component 22 is movably connected to the bottom of the cabinet 1. The first sliding component 22 rotates at the bottom of the cabinet 1 by the horizontal force of the linear displacement mechanism 21. The rotation switches the first sliding component 22 to a vertical state or an inclined state. When the first sliding component 22 is in an inclined state, its bottom does not contact the ground and the cabinet 1 is supported by the support foot 11. When the first sliding component 22 is in a vertical state, its bottom rolls in contact with the ground and the cabinet 1 is moved by the first sliding component 22.

[0037] Specifically, the linear displacement mechanism 21 includes a fixed plate 211 and a second sleeve 215. The fixed plate 211 has two symmetrically arranged sliding grooves 212. A rotating shaft 23 passes through the fixed plate 211. Specifically, the fixed plate 211 can have a through hole for the rotating shaft 23 to pass through, and a bearing can be installed at the through hole to allow the rotating shaft 23 to rotate within the through hole. The second sleeve 215 is sleeved on the rotating shaft 23 and rotates with the rotating shaft 23. Two connecting plates 216 are symmetrically arranged on the same end of the second sleeve 215. One connecting plate 216 is connected to the first slider 213 via a first connecting rod 217. The two ends of the first connecting rod 217 are rotatably connected to the connecting plate 216 and the first slider 213, respectively. More specifically, a shaft can be provided between the connecting plate 216 and the first slider 213, and the two ends of the first connecting rod 217 are sleeved and rotated... The first slider 213 is mounted on the shaft, and the other connecting plate 216 is connected to the second slider 214 via the second connecting rod 218. The connection between the second connecting rod 218, the connecting plate 216, and the second slider 214 is similar to that of the first connecting rod 217. The first slider 213 and the second slider 214 are slidably mounted on the slide groove 212 and positioned on both sides of the second sleeve 215. Specifically, the two slide grooves 212 are arranged symmetrically from top to bottom, with their opening ends facing each other, and there is a gap between them. The exposed portions of the first slider 213 and the second slider 214 can be used to connect with the first connecting rod 217 and the second connecting rod 218. The first slider 213 and the second slider 214 are respectively hinged to the two first sliding components 22. Specifically, the side of the first slider 213 and the second slider 214 away from the second sleeve 215 is hinged to the first sliding component 22.

[0038] In this embodiment, a fixed shaft 26 is provided at the bottom of the cabinet 1; the first sliding assembly 22 includes a first roller 221, a first bracket 222, a first support plate 223 and a third sleeve 224. One end of the first support plate 223 is connected to the first bracket 222 and the other end is connected to the third sleeve 224. The third sleeve 224 is rotatably disposed on the outer wall of the fixed shaft 26. The first roller 221 is mounted on the first bracket 222; the first slider 213 and the second slider 214 are respectively hinged to the first support plate 223; preferably, the first slider 213 and the second slider 214 are respectively hinged to the first support plate 223 through a connecting rod 25.

[0039] The principle by which the linear displacement mechanism 21 in this embodiment realizes the rotation of the first sliding component 22 is as follows: When the rotating shaft 23 is driven to rotate by the motor, the second sleeve 215 rotates along with the rotating shaft 23, such as Figure 8When rotating counterclockwise as shown, the first connecting rod 217 and the second connecting rod 218 respectively push the first slider 213 and the second slider 214 to move away from the second sleeve 215. Then, the horizontal movement of the first slider 213 and the second slider 214 drives the first sliding assembly 22 to rotate around the fixed axis 26. During the rotation of the first sliding assembly 22, when the first roller 221 begins to contact the ground, the first sliding assembly 22 is still in an inclined state and is still supported by the support foot 11, thus ensuring the stability of the cabinet 1. The first slider 213 and the second slider 214 continue to move horizontally, and the first sliding assembly 22 continues to rotate until the first sliding assembly 22 is in a vertical state. At this time, the bottom of the support foot 11 is no longer in contact with the ground and leaves the ground. The first sliding assembly 22 supports the cabinet 1. The first sliding assembly 22 is a complete fixed structure, which has better stability than the existing connecting rod structure support. The first slider 213 and the second slider 214 do not move, so the first sliding assembly 22 does not rotate. Therefore, the overall stability is good, and the cabinet 1 can be moved by the first roller 221.

[0040] Support component 3 is used to support the side wall of the moving cabinet 1 to prevent the cabinet 1 from tilting during movement. Support component 3 is located on the outer side wall of the cabinet 1 and can be rotated to tilt, thus supporting the cabinet 1 and retracting it parallel to the side wall of the cabinet 1. Support component 3 includes a support rod 31, with a second sliding component 32 located at the end of the support rod 31 furthest from the cabinet 1. The support rod 31 rotates to allow the second sliding component 32 to slide into contact with the ground when the cabinet 1 is moved. Specifically, the second sliding component 32 includes a second roller and a second bracket. The second roller is mounted on the second bracket, and the end of the support rod 31 furthest from the cabinet 1 is connected to the second bracket. This connection can be fixed, hinged, or rotatable. In a rotatable connection, a shaft is mounted on the second bracket, and a cylinder fitted onto the shaft is located at the end of the support rod 31.

[0041] Preferably, the bottom of the cabinet 1 is recessed upward to form a first groove 12 and a second groove 13. The first groove 12 is provided on both sides of the second groove 13. The first groove 12 and the second groove 13 are connected. The rotating shaft 23 and the motor are installed in the second groove 13. The first sliding component 22 and the linear displacement mechanism 21 are installed in the first groove 12. Specifically, the fixing plate 211 is fixed to the groove wall of the first groove 12. The second sleeves 215 in the two first grooves 12 are arranged opposite to each other.

[0042] In this embodiment, the support rod 31 is implemented as follows: the support assembly 3 further includes a positioning shaft 33, which is mounted on the outer wall of the cabinet 1 via a fixing member 34. The positioning shaft 33 is fixedly connected to the fixing member 34, and is horizontally positioned with a gap between it and the outer wall of the cabinet 1. One end of the support rod 31 is rotatably connected to the positioning shaft 33. By rotating the support rod 31, the second sliding assembly 32 can slide into contact with the ground. The specific rotational connection method is as follows: Figure 10 , Figure 11 As shown, one end of the support rod 31 is rotatably mounted on the outer wall of the positioning shaft 33 via the first sleeve 35. The positioning shaft 33 is provided with a locking member 36 for restricting the circumferential displacement of the first sleeve 35. When the locking member 36 is locked, the first sleeve 35 cannot rotate on the positioning shaft 33. When the locking member 36 is released, the first sleeve 35 can rotate on the positioning shaft 33 under the action of external force. In a specific case, the locking component 36 includes a positioning cylinder 361, which has a large end and a small end. The small end of the positioning cylinder 361 is sleeved and fixed to the outer wall of the positioning shaft 33, and the large end of the positioning cylinder 361 is coaxially positioned outside the first sleeve 35. The large end of the positioning cylinder 361 does not provide resistance to the rotation of the first sleeve 35. A positioning groove 351 is provided on the outer wall of the first sleeve 35, and a circumferential limiting block 364 is rotatably provided on the side wall of the positioning cylinder 361. The circumferential limiting block 364 has an eccentric structure. By rotating the circumferential limiting block 364, the circumferential limiting block 364 can be pressed or released at the positioning groove 351 on the outer wall of the first sleeve 35. Specifically, a limiting shaft 362 is rotatably mounted on the large end sidewall of the positioning cylinder 361, and a circumferential limiting block 364 is mounted on the limiting shaft 362. The circumferential limiting block 364 and the limiting shaft 362 are not coaxially mounted. There is a large distance between the outer wall of one side of the circumferential limiting block 364 and the limiting shaft 362, and a smaller distance between the outer wall of the other side of the circumferential limiting block 364 and the limiting shaft 362. By applying a force to the circumferential limiting block 364, synchronous rotation of the circumferential limiting block 364 and the limiting shaft 362 can be achieved. Through rotation, different positions of the circumferential limiting block 364 can be achieved. The position is set corresponding to the positioning groove 351. When the side of the circumferential limiting block 364 with a large distance between its outer wall and the limiting shaft 362 rotates into the positioning groove 351, the circumferential limiting block 364 and the positioning cylinder 361 press against the first sleeve 35. At this time, the first sleeve 35 cannot rotate. When the side of the circumferential limiting block 364 with a small distance between its outer wall and the limiting shaft 362 rotates into the positioning groove 351, the circumferential limiting block 364 does not contact the groove wall of the positioning groove 351, that is, it does not press against the first sleeve 35, and the first sleeve 35 can rotate. Preferably, an operating handle 365 for manual operation is provided on the circumferential limiting block 364.

[0043] In a preferred embodiment, the positioning groove 351 is an annular groove, and multiple circumferential limiting blocks 364 are arranged along the circumference of the positioning groove 351. Preferably, the axial section of the positioning groove 351 is a circular arc groove, and the outer wall of the circumferential limiting block 364 is a curved surface structure.

[0044] Preferably, the support rod 31 is a telescopic rod, which can be rotated to different angles by telescopic movement of the support rod 31.

[0045] In specific implementation, support components 3 are provided on the symmetrical side walls of the cabinet 1 on both sides of the cabinet door; or support components 3 are provided on the symmetrical side walls of the cabinet 1 on both sides of the cabinet door and on the side wall opposite to the cabinet door.

[0046] The working principle of the support rod 31 in this embodiment is as follows: When it is necessary to move the cabinet 1, rotate the circumferential limiting block 364 to release the pressure of the circumferential limiting block 364 on the first sleeve 35, and then rotate the support rod 31 to move the second sliding component 32 toward the ground until the second roller of the second sliding component 32 contacts the ground. At this time, the support rod 31 and the outer wall of the cabinet 1 form an angle of less than 90°, preferably less than 60°. That is, the support rod 31 is in an inclined state at this time. A stable triangular structure is formed between the support rod 31, the ground and the cabinet 1, which can prevent the cabinet 1 from tipping over during the movement.

[0047] The installation method of the cabinet installation device in this embodiment includes the following steps: S1. When it is necessary to move cabinet 1, the motor makes the rotating shaft 23 rotate, causing the first slider 213 and the second slider 214 to move in opposite directions, pushing the first sliding component 22 to rotate, so that the first sliding component 22 rotates from the inclined state to the vertical state. When the first sliding component 22 rotates to the vertical state, the first sliding component 22 rolls into contact with the ground. S2. Rotate the support rod 31 until the second sliding component 32 makes sliding contact with the ground.

[0048] In this embodiment, a moving component 2 and a supporting component 3 are respectively set at the bottom and body of the cabinet 1. When the cabinet 1 is moved, the first sliding component 22 at the bottom of the moving component 2 extends to facilitate the movement of the cabinet 1. The supporting rod 31 of the supporting component 3 opens to a tilted supporting state to prevent the cabinet 1 from tipping over during the movement, thus improving the stability of the cabinet 1. In this embodiment, the extension and retraction of the first sliding component 22 is achieved by rotating the pivot 23, which causes the first slider 213 and the second slider 214 in the linear displacement mechanism 21 to move horizontally and linearly. The horizontal linear displacement of the first slider 213 and the second slider 214 is converted into the rotational power of the first sliding component 22. The rotation of the first sliding component 22 enables it to extend and retract from the bottom of the cabinet 1, making the supporting stability of the first sliding component 22 better. It can also achieve synchronous control of the four first sliding components 22, ensuring that the four first sliding components 22 land synchronously, avoiding tilting caused by the four first sliding components 22 not landing synchronously due to individual control.

[0049] Example 2: This embodiment is based on Embodiment 1. An axial limiting block 363 is further provided on the limiting shaft 362. The outer wall of the axial limiting block 363 is placed within the positioning groove 351 and does not compress the first sleeve 35. The axial limiting block 363 is used to limit the relative axial displacement of the positioning cylinder 361 and the first sleeve 35. Specifically, the axial limiting block 363 is a disc structure coaxially arranged with the limiting shaft 362. It rotates with the rotation of the limiting shaft 362. One side of the outer wall of the axial limiting block 363 protrudes radially from the circumferential limiting block 364. When the circumferential limiting block 364 loses its pressure on the first sleeve 35, the portion of the axial limiting block 363 protruding from the circumferential limiting block 364 is placed within the positioning groove 351 and does not contact the bottom of the positioning groove 351, thus blocking the axial displacement of the first sleeve 35 but not affecting the rotation of the first sleeve 35.

[0050] Example 3: This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that the way the positioning cylinder 361 locks the first sleeve 35 is different: In this embodiment, the positioning cylinder 361 and the first sleeve 35 are locked together by a pin and a hole. Specifically, a first through hole can be provided on the large end side wall of the positioning cylinder 361, and a first fixing hole and a second fixing hole can be provided on the outer wall of the first sleeve 35. When the support rod 31 rotates to an inclined state to support the cabinet 1, the first sleeve 35 rotates to the position corresponding to the first fixing hole and the first through hole, and is fixed in the first through hole and the first fixing hole by a pin. When the support rod 31 rotates to a vertical state and the second sliding component 32 is at the top, the first sleeve 35 rotates to the position corresponding to the second fixing hole and the first through hole, and is fixed in the first through hole and the second fixing hole by a pin.

[0051] Example 4: This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that the way the support rod 31 is rotated is different. In this embodiment, one end of the support rod 31 is fixedly connected to the positioning shaft 33, and the second sliding component 32 slides in contact with the ground by rotating the positioning shaft 33.

[0052] Specifically: The positioning shaft 33 is rotatably mounted within the fixing member 34. When the positioning shaft 33 rotates to the designated position, it is fixed by a locking mechanism, which uses a pin and a hole combination. Specifically, a third fixing hole is provided on the outer wall of the cabinet 1, and a third through hole and a fourth through hole are provided on the positioning shaft 33. When the support rod 31 rotates to an inclined state to support the cabinet 1, the positioning shaft 33 rotates to the position corresponding to the third through hole and the third fixing hole, and is fixed in the third through hole and the third fixing hole with a pin. When the support rod 31 rotates to a vertical state and the second sliding component 32 is at the top, the positioning shaft 33 rotates to the position corresponding to the fourth through hole and the third fixing hole, and is fixed in the fourth through hole and the third fixing hole with a pin.
