Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a support for an electrical cabinet with stable support. Background Art

[0002] The bottom of the electrical cabinet is supported on the ground by installing supports. The supports bear the weight of the entire electrical cabinet and ensure that the electrical cabinet is placed stably on the ground.

[0003] Existing small and medium-sized electrical cabinets typically have universal casters installed at the four corners of the cabinet to facilitate mobility. However, due to the small contact area between the wheel and the ground, the cabinet is unstable during transportation, maintenance, or when subjected to external forces, and is prone to tilting or shaking. This is especially true in temporary prefabricated buildings such as construction sites, where internal components of the cabinet can be damaged. Furthermore, the universal casters have a limited load-bearing capacity, and if the cabinet is too heavy, they may damage or deform the wheels. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a support for an electrical cabinet with stable support.

[0005] The technical solution of this utility model is as follows:

[0006] A stably supporting electrical cabinet support, comprising universal wheels arranged at the four corners of the electrical cabinet, the universal wheels comprising a wheel body and a threaded rod vertically arranged above the wheel body, a connecting piece being threadedly connected to the threaded rod, the connecting piece comprising a nut and a sleeve, an annular groove being formed on the outer surface of the lower portion of the nut along the circumferential direction, the sleeve being sleeved on the annular groove and being rotatably connected to the nut;

[0007] The sleeves of the two universal wheels on the same side are connected by a connecting rod, and a telescopic main rod that can be extended and retracted is provided under the connecting rod. The telescopic main rod includes a first long tube and a second long tube that are sleeved up and down. A support platform that can be pressed downward against the ground is provided under the second long tube. The first long tube and the second long tube can be locked by a locking piece.

[0008] The universal wheels are connected to the four corners of the bottom plate of the electrical cabinet through threaded rods. By loosening or tightening the nuts, the contact between the universal wheels and the ground can be adjusted according to the height of the ground to ensure the stability of the electrical cabinet. The rotation of the nuts does not affect the connection between the sleeve and the connecting rod on it. When transporting or repairing the electrical cabinet, after locking the four universal wheels, the support platform is moved down to contact the ground and locked with the locking parts, so that the support platform and the universal wheels form a stable support for the electrical cabinet.

[0009] The specific structure of the above-mentioned locking member is that the locking member includes a downward pressure rod and a plug-in rod located below the connecting rod. The lower part of the downward pressure rod is connected to the connecting rod through a vertically arranged telescopic rod. The first long tube and the second long tube are both provided with plug-in interfaces adapted to the plug-in rod, and the plug-in interfaces of the first long tube and the second long tube are arranged correspondingly. When the support platform is moved downward until it contacts the ground, the plug-in interfaces of the first long tube and the second long tube can overlap, which facilitates the insertion of the plug-in rod into the plug-in interfaces of the first long tube and the second long tube to form a locked state.

[0010] Regarding the connection structure of the plug-in rod to the lower pressure rod, a through hole perpendicular to the axis of the telescopic main rod is provided in the middle of the lower pressure rod, and the plug-in rod is inserted into the through hole through an elastic member.

[0011] There is a brake paddle on the universal wheel for braking. Since the rotation of the universal wheel is uncertain, the position of the brake paddle is uncertain. Since the electrical cabinet is generally placed in a small space, if the position of the electrical cabinet is fixed, the brake paddle is located inside the electrical cabinet, which is not convenient for locking the universal wheel by shifting down. For this reason, an arc-shaped lower pressure plate is provided at both ends of the lower pressure rod, and the orthographic projection of the arc-shaped lower pressure plate is located within the orthographic projection of the bottom plate of the electrical cabinet. The axis of the arc-shaped lower pressure plate is coaxial with the axis of the threaded rod. The universal wheel has a brake paddle, and the arc-shaped lower pressure plate is located above the brake paddle.

[0012] In order to facilitate the arc-shaped downward pressure plate to press the brake paddle downward when the connecting rod is pressed down, there is no need to insert the connecting rod and press down the brake paddle separately. The maximum vertical distance between the connecting rod and the horizontal plane where the plug interface is located is greater than the minimum vertical distance between the arc-shaped downward pressure plate and the horizontal plane where the brake paddle is located.

[0013] Regarding the structure of the arc-shaped lower pressure plate, the arc of the arc-shaped lower pressure plate is greater than 180°, and its opening is close to the outer side of the electrical cabinet along the length direction. The arc-shaped lower pressure plate will not leak out of the bottom plate of the electrical cabinet, and will not affect the movement and daily use of the electrical cabinet.

[0014] In order to facilitate pressing the down-pressing rod downward, two groups of down-pressing rods are provided. The two groups of down-pressing rods are arranged in parallel, and the vertical distance between one down-pressing rod and the outer side of the electrical cabinet along the length direction is not greater than 2 cm.

[0015] Regarding the installation structure of the threaded rod and the base plate, the upper part of the threaded rod passes through the base plate of the electrical cabinet and is threadedly connected to the nut, and the base plate is located between the nut and the nut.

[0016] The beneficial effects of the present invention are:

[0017] The support platform is moved down until it contacts the ground and is locked by a locking member, thereby greatly increasing the contact area with the ground. The support platform cooperates with the universal wheels to form a stable support for the electrical cabinet, thereby preventing the electrical cabinet from shaking, tilting or tipping over during transportation, maintenance or when encountering external forces. When not in use, the support platform can be stored by adjusting the length of the first long tube and the second long tube;

[0018] The support platform is connected to the bottom of the connecting rod through a telescopic main rod, and the connecting rod is connected to the two sleeves on the same side, so that the support platform does not need to be drilled on the bottom plate of the electrical cabinet for installation, which will not cause irreversible damage to the electrical cabinet. In addition, the support platform and the telescopic main rod can be installed on existing universal wheels, which can be directly modified on existing small and medium-sized electrical cabinets, thereby expanding the scope of use of the support platform.

[0019] There is a brake paddle on the universal wheel for braking. Since the rotation of the universal wheel is uncertain, the position of the brake paddle is uncertain. Since the electrical cabinet is generally placed in a small space, if the position of the electrical cabinet is fixed, the brake paddle is located inside the electrical cabinet, which is not convenient for shifting down to lock the universal wheel. For this reason, an arc-shaped lower pressure plate is provided, and the lower pressure plate drives the connecting rod and the arc-shaped lower pressure plate to move downward at the same time. When the connecting rod is inserted into the plug interface, the brake paddle located on the inside of the electrical cabinet can be pressed down at the same time to lock the universal wheel, and there is no need to lock the universal wheel located on the inside of the bottom plate separately.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 10 As shown, a stable electrical cabinet support includes universal wheels 2 arranged at the four corners of the electrical cabinet 1. The universal wheels 2 include a wheel body and a threaded rod 3 vertically arranged above the wheel body. A connecting piece is threadedly connected to the threaded rod 3. The connecting piece includes a nut 4 and a sleeve 5. An annular groove 41 is provided on the lower outer surface of the nut 4 in the circumferential direction. The sleeve 5 is sleeved on the annular groove 41 and is rotatably connected to the nut 4. The upper part of the threaded rod 3 passes through the bottom plate of the electrical cabinet 1 and is threadedly connected to the nut 14. The bottom plate is located between the nut 14 and the nut 4.

[0034] See also Figure 5 、 Figure 6 、 Figure 7 and Figure 9 As shown, the sleeves 5 of the two universal wheels 2 on the same side are connected by a connecting rod 6, and a telescopic main rod that can be extended and retracted is provided below the connecting rod 6. The telescopic main rod includes a first long tube 7 and a second long tube 8 that are sleeved up and down. The first long tube 7 is inserted into the second long tube 8, and the upper end of the first long tube 7 is connected to the lower end surface of the connecting rod 6. A support platform 16 that can be pressed downward against the ground is provided below the second long tube 8. The first long tube 7 and the second long tube 8 can be locked by a locking member.

[0035] See also Figure 7 and Figure 8As shown, the specific structure of the above-mentioned locking member is that the locking member includes a lower pressure rod 10 and a plug-in rod 9 located below the connecting rod 6. The lower pressure rod 10 is arranged horizontally, and the plug-in rod 9 is arranged vertically to the lower pressure rod 10 and the first long tube 7 respectively. The lower part of the lower pressure rod 10 is connected to the connecting rod 6 through two vertically arranged telescopic rods 15. The first long tube 7 and the second long tube 8 are both provided with a plug-in interface 11 adapted to the plug-in rod 9. The plug-in interfaces 11 of the first long tube 7 and the second long tube 8 can be correspondingly provided with multiple ones, so that when the support platform 16 is moved downward to contact the ground, the plug-in interface 11 of the first long tube 7 can coincide with the plug-in interface 11 of the second long tube 8, so that the plug-in rod 9 is inserted into the plug-in interface 11 of the first long tube 7 and the second long tube 8, so that the support platform 16 is locked.

[0036] Regarding the connection structure of the plug rod 9 to the lower pressure rod 10, a through hole 101 perpendicular to the axis of the telescopic main rod is provided in the middle of the lower pressure rod 10. The plug rod 9 is inserted into the through hole 101 through an elastic member 12. The elastic member 12 is a compression spring. The elastic member 12 is sleeved on the outside of the plug rod 9. One end of the elastic member 12 is connected to the through hole 101, and the other end is connected to the plug rod 9. In the initial state, the plug rod 9 is disengaged from the plug interface 11, the elastic member 12 is in a compressed state, and the plug rod 9 is located above the plug interface 11. When the lower pressure rod 10 drives the plug rod 9 to move downward, one end of the plug rod 9 can move downward in the vertical direction when it contacts the outer wall of the second long tube 8. When it reaches the plug interface 11, the plug rod 9 can be inserted into the plug interface 11, and the compression spring is reset.

[0037] The function of the above structure is that the universal wheel 2 is connected to the four corners of the bottom plate of the electrical cabinet 1 through the threaded rod 3. By loosening or tightening the nut 4, the contact between the universal wheel 2 and the ground can be adjusted according to the height of the ground to ensure the stability of the electrical cabinet 1. The rotation of the nut 4 does not affect the connection between the sleeve 5 and the connecting rod 6 thereon. When transporting or repairing the electrical cabinet 1, after locking the four universal wheels 2, the support platform 16 is moved down to contact the ground and locked by the locking piece, so that the support platform 16 cooperates with the universal wheel 2 to form a stable support for the electrical cabinet 1.

[0038] The universal wheel 2 in the prior art has a brake paddle 21 for braking. In actual use, when the electrical cabinet 1 is moved, the position of the brake paddle 21 is uncertain due to the uncertain rotation of the universal wheel 2. Since the electrical cabinet 1 is generally placed in a small space, if the position of the electrical cabinet 1 is fixed, the brake paddle 21 is located inside the electrical cabinet 1, which is not convenient for shifting down to lock the universal wheel 2. For this reason, an arc-shaped lower pressure plate 13 is provided at both ends of the lower pressure rod 10, and the orthographic projection of the arc-shaped lower pressure plate 13 is located within the orthographic projection of the bottom plate of the electrical cabinet 1. The axis of the arc-shaped lower pressure plate 13 is coaxial with the axis of the threaded rod 3. The universal wheel 2 has a brake paddle 21, and the arc-shaped lower pressure plate 13 is located above the brake paddle 21.

[0039] To facilitate downward movement of the curved pressing plate 13 to press the brake paddle 21 when the plug-in rod 9 is pressed downward, eliminating the need to separately insert the plug-in rod 9 and press down the brake paddle 21, the maximum vertical spacing between the plug-in rod 9 and the horizontal plane containing the plug-in port 11 is greater than the minimum vertical spacing between the curved pressing plate 13 and the horizontal plane containing the brake paddle 21. Regarding the structure of the curved pressing plate 13, its curvature is greater than 180°, enabling downward movement of the brake paddle 21 to a greater extent than the inwardly accessible area. Furthermore, its opening is located near the outer side of the electrical cabinet 1 along its length, ensuring that the curved pressing plate 13 does not protrude from the bottom plate of the electrical cabinet 1, thus not affecting its movement and daily use.

[0040] In order to facilitate pressing the down-pressing rod 10, two groups of down-pressing rods 10 are provided. The two groups of down-pressing rods 10 are arranged in parallel, and the vertical distance between one down-pressing rod 10 and the outer side of the electrical cabinet 1 along the length direction is not greater than 2 cm, so that at least one down-pressing rod 10 is arranged close to the outer side, which is convenient for the staff to press the down-pressing rod 10 downward by hand or foot, thereby realizing the synchronous locking of the support platform 16 and the universal wheel 2.
