Description

Technical Field

[0001] The utility model belongs to the technical field of supporting structures, and in particular relates to a grounding type supporting structure for a power cabinet. Background Art

[0002] The power cabinet is a device used to control the power supply of power equipment. It usually contains power switches, fuses, terminals, power metering instruments and other components. It is widely used in industrial production and urban power grids. There are many types of power cabinets, such as fixed panel switch cabinets, protective (enclosed) switch cabinets and drawer switch cabinets. Each type has its own specific application scenarios and characteristics. Some power cabinets need to be able to move easily due to application scenarios. Therefore, universal wheels are set under the cabinet body to support and move the cabinet body. Although the universal wheels generally have brakes for stopping, they can only brake the wheels and cannot brake the bearings used to adjust the direction of travel. Therefore, when the power cabinet is running, the universal wheels may swing due to vibration, causing the cabinet body to swing, affecting stability, and increasing the wear of the universal wheels. Although this problem can be solved by setting a fixed support structure that can be raised or lowered or setting the universal wheels as a structure that can be raised or lowered, it will greatly increase the structural complexity of the power cabinet and it is not convenient to fix the power cabinet. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a grounding support structure for a power cabinet, which avoids the shaking and instability of the cabinet due to the horizontal rotation of the universal wheel, takes into account the convenience of mobility while conveniently fixing the power cabinet.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a grounding support structure for a power cabinet, comprising a cabinet body, a base is provided at the bottom of the cabinet body, a universal wheel is installed at the bottom of the base, a mounting groove is provided inside the base, a connecting rod is installed on the inner side of the mounting groove, the front end of the connecting rod is connected to a threaded transmission plate, the front end of the base is connected to a screw mounting seat, a transmission screw is rotatably installed on the screw mounting seat, the transmission screw is spirally connected to the screw mounting seat, a limiting rod is connected to the bottom of the connecting rod, a slide rail is installed at the bottom of the base, a slider is installed inside the slide rail, an L-shaped frame is installed on the side of the slider, a limiting frame is installed on one side of the L-shaped frame, and the other end of the limiting frame is connected to an arc rod.

[0005] The beneficial effects of the utility model are as follows: the device is moved by the universal wheel. When the device is moved to the installation position, the universal wheel is first braked by the brake on the universal wheel, and then the pedal is rotated downward to open and supported by the support seat. At this time, the foot can be stepped on the pedal to push the slider along the slide rail to approach the universal wheel, thereby driving the limit rod and the arc rod to move toward the universal wheel. Since the arc rod is provided, even if the direction of the universal wheel is not in the same straight line as the direction of the cabinet at this time, the universal wheel can be turned to the direction that is in the same straight line as the direction of the device. In a straight line, the limit rod then continues to move, clamping the universal wheel from both sides so that it cannot rotate, thus avoiding the problem of shaking and instability of the cabinet due to the horizontal rotation of the universal wheel. Then, the knob is turned to drive the transmission screw to rotate, and the spiral transmission is used to drive the threaded transmission plate together with the connecting rod and the limit rod to descend, so that the bottom end of the limit rod is lowered to the inner side of the limit frame, which blocks the limit seat and prevents the limit frame from leaving from both sides of the universal wheel. The position of the device is fixed, and the power cabinet can be conveniently fixed while taking into account the convenience of mobility.

[0006] To save space:

[0007] As a further improvement of the above technical solution: a support seat and a damping bearing seat are installed on the side of the L-shaped frame, and a pedal is rotatably installed on the damping bearing seat.

[0008] The beneficial effect of this improvement is: the pedal is rotated downward to open and supported by the support seat. At this time, the foot can be stepped on the pedal to push the slider along the slide rail to approach the universal wheel. After the movement of the limit frame is completed, the pedal can be folded again to save space.

[0009] To brake the swivel wheel:

[0010] As a further improvement of the above technical solution: the universal wheel is a universal wheel with a brake.

[0011] The beneficial effect of this improvement is that the universal wheel adopts a universal wheel with a brake, so that the universal wheel can be braked to stop.

[0012] To facilitate turning the drive screw:

[0013] As a further improvement of the above technical solution: the top end of the transmission screw is connected to the knob.

[0014] The beneficial effect of this improvement is that the knob connection is used to facilitate the rotation of the transmission screw.

[0015] To prevent the limiter from moving away from both sides of the universal wheel:

[0016] As a further improvement of the above technical solution: an integrally formed limiting seat is provided on the inner side of the limiting frame.

[0017] The beneficial effect of this improvement is that the limiting seat is used to cooperate with the limiting rod to prevent the limiting frame from moving away from the two sides of the universal wheel.

[0018] In order to be able to move two sets of slides connected by a crossbar by pushing only one side of the pedal:

[0019] As a further improvement of the above technical solution: a through groove is penetrated through one side of the slide rail, and a cross bar is connected between the left and right sets of slide blocks.

[0020] The beneficial effect of this improvement is that, through the connection of the cross bar, the device can drive the two sets of sliders connected by the cross bar to move by only pushing the pedal on one side.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] like Figure 1-5As shown, a grounding support structure for a power cabinet comprises a cabinet body 1, a base 2 is provided at the bottom of the cabinet body 1, a universal wheel 3 is installed at the bottom of the base 2, a mounting groove 4 is provided inside the base 2, a connecting rod 5 is installed on the inner side of the mounting groove 4, a front end of the connecting rod 5 is connected to a threaded transmission plate 6, a front end of the base 2 is connected to a screw mounting seat 7, a transmission screw 8 is rotatably installed on the screw mounting seat 7, the transmission screw 8 is connected to the screw mounting seat 7 by spiral transmission, a limiting rod 10 is connected to the bottom of the connecting rod 5, a slide rail 11 is installed at the bottom of the base 2, a slider 12 is installed inside the slide rail 11, an L-shaped frame 13 is installed on the side of the slider 12, a limiting frame 14 is installed on one side of the L-shaped frame 13, and the other end of the limiting frame 14 is connected to an arc rod 15.

[0030] The device is moved by the universal wheel 3. When the device is moved to the installation position, the universal wheel 3 is first braked by the brake on the universal wheel 3, and then the pedal 18 can be rotated downward to open and supported by the support seat 16. At this time, the foot can be stepped on the pedal 18 to push the slider 12 along the slide rail 11 to approach the universal wheel 3, thereby driving the limit rod 10 and the arc rod 15 to move toward the universal wheel 3. Since the arc rod 15 is provided, even if the direction of the universal wheel 3 is not in the same straight line with the direction of the cabinet at this time, the universal wheel 3 can be turned to be in the same straight line with the direction of the device. Then the limit rod 10 continues to move, clamping the universal wheel 3 from both sides so that it cannot rotate, thereby avoiding the cabinet 1 from shaking and becoming unstable due to the horizontal rotation of the universal wheel 3. Then, the knob 9 is turned to drive the transmission screw 8 to rotate, and the screw transmission is used to drive the threaded transmission plate 6 together with the connecting rod 5 and the limit rod 10 to descend, so that the bottom end of the limit rod 10 descends to the inner side of the limit frame 14, which blocks the limit seat 19 and prevents the limit frame 14 from leaving from both sides of the universal wheel 3, thereby completing the position fixation of the device. While taking into account the convenience of mobility, the power cabinet can be conveniently fixed and placed.

[0031] A support seat 16 and a damping bearing seat 17 are installed on the side of the L-shaped frame 13, and a pedal 18 is rotatably installed on the damping bearing seat 17.

[0032] The pedal 18 is turned downward and opened, and supported by the support seat 16. At this time, the foot can be stepped on the pedal 18 to push the slider 12 along the slide rail 11 to approach the universal wheel 3. After the movement of the limit frame 14 is completed, the pedal 18 can be folded again.

[0033] The universal wheel 3 is a universal wheel with a brake.

[0034] The universal wheel 3 is a universal wheel with a brake, so that the universal wheel 3 can be stopped by braking.

[0035] The top end of the transmission screw 8 is connected to the knob 9 .

[0036] The knob 9 is connected to facilitate the rotation of the transmission screw 8.

[0037] An integrally formed limiting seat 19 is disposed on the inner side of the limiting frame 14 .

[0038] The limiting seat 19 is used to cooperate with the limiting rod 10 to prevent the limiting frame 14 from moving away from the two sides of the universal wheel 3.

[0039] A through slot is formed on one side of the slide rail 11 , and a cross bar 20 is connected between the left and right sets of slide blocks 12 .

[0040] Through the connection of the cross bar 20, the device can drive the two groups of sliders 12 connected by the cross bar 20 to move by only pushing the pedal 18 on one side.

[0041] The working principle and use process of the utility model are as follows: the device is moved by the universal wheel 3. When the device is moved to the installation position, the universal wheel 3 is first braked by the brake on the universal wheel 3, and the pedal 18 can be rotated downward to open it, and it is supported by the support seat 16. At this time, the foot can be stepped on the pedal 18 to push the slider 12 along the slide rail 11 to approach the universal wheel 3, thereby driving the limit rod 10 and the arc rod 15 to move toward the universal wheel 3. Since the arc rod 15 is provided, even if the direction of the universal wheel 3 is not in the same straight line as the direction of the cabinet body at this time, the universal wheel 3 can be moved to the same straight line as the direction of the device, and then the limit rod 10 continues to move, clamping the universal wheel 3 from both sides so that it cannot rotate, thereby avoiding the problem of shaking and instability of the cabinet body 1 due to the horizontal rotation of the universal wheel 3. The movable knob 9 drives the transmission screw 8 to rotate, and the spiral transmission drives the threaded transmission plate 6 together with the connecting rod 5 and the limit rod 10 to descend, so that the bottom end of the limit rod 10 descends to the inner side of the limit frame 14, and the limit seat 19 is blocked to prevent the limit frame 14 from leaving from both sides of the universal wheel 3, thereby completing the position fixation of the device, while taking into account the convenience of mobility and conveniently fixing the power cabinet. When it is necessary to move the device, it is only necessary to rotate the knob 9 in the opposite direction to drive the connecting rod 5 and the limit rod 10 to rise. At this time, the limit of the universal wheel 3 by the limit frame 14 can be released. After the brake of the universal wheel 3 is released, the device can be pushed to move. When multiple groups of the devices are placed one by one in a row, when the cabinet 1 located in the middle is placed, only the universal wheel 3 located on the front side of the cabinet 1 is braked so that the brake can be released later.
