DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figures 1 to 13, this embodiment provides a technical solution: an adjustable power distribution cabinet elevation bracket, comprising a storage slot 1, a support frame 2 is symmetrically arranged on both sides of the storage slot 1, the support frame 2 has two support legs 201, the support frame 2 comprises a sliding slot 202 opened at the upper end of the support frame 2, an adjustment support seat 203 slidably installed at the upper end of the support frame 2, a first bolt 204 fixed to the outer wall of the adjustment support seat 203, and a nut 205 threadedly connected to the outer side of the first bolt 204, the first bolt 204 is inserted into the sliding slot 202, and the nut 205 is tightly pressed against the outer wall of the support frame 2. When installing the power distribution cabinet, the power distribution cabinet is mounted on the two adjustment support seats 203, and then the bolts are passed through the openings on the adjustment support seats 203 to fix the power distribution cabinet on the adjustment support seats 203. When adjusting the installation height, the nut 205 is loosened by rotating it, and then the adjustment support seat 203 is moved. This is a prior art and will not be described in detail here.

[0044] The support leg 201 is rotatably connected to the side wall of the storage tank 1, and a protective cover 3 is sleeved on the outer side of the support leg 201. A moving component 4 for adjusting the position of the protective cover 3 is installed on the support leg 201. When the support frame 2 is folded at the top of the storage tank 1 in a horizontal posture, the moving component 4 drives the protective cover 3 to move to the end of the support leg 201. A positioning component 5 is installed on the storage tank 1 to position the two support legs 201 when they are unfolded in a vertical posture;

[0045] Because both support frames 2 need to be rotated to be parallel above the storage slot 1, and under the size of the storage slot 1 shown in the figure, in the folded state of the entire bracket, one support frame 2 on one side needs to be stacked on top of one support frame 2 on the other side, so the height of the axis of rotation of one support frame 2 on one side and the storage slot 1 is higher than the height of the axis of rotation of one support frame 2 on the other side and the storage slot 1, so as to ensure that one support frame 2 on one side is stacked on one support frame 2 on the other side in the folded state;

[0046] By rotating the support frames 2 on both sides and installing them on the storage slot 1, the entire support can be folded during transportation and storage, so that both support frames 2 are rotated on the storage slot 1 to be in a horizontal state, thereby greatly reducing the volume of the entire support, improving the passability during transportation, and being more convenient for movement. In addition, the volume is greatly reduced during storage, the size of the occupied space is greatly reduced, and the space utilization rate during storage is improved;

[0047] The moving assembly 4 includes a square groove 401 opened on the support foot 201, and the side of the support foot 201 away from the opposite support frame 2 is rotatably connected to the first flip plate 402 through an axle pin, and the end of the first flip plate 402 is rotatably connected to the second flip plate 403 through an axle pin. The connection between the first flip plate 402 and the second flip plate 403 is arranged to protrude between the two support frames 2 through the square groove 401, and the end of the second flip plate 403 away from the first flip plate 402 is rotatably connected to the push bar 404 through an axle pin. Two limiting slide frames are fixed to the side of the support foot 201 close to the push bar 404 405, the push bar 404 is slidably connected to the inner wall of the limiting slide frame 405, the end of the push bar 404 away from the second flip plate 403 is fixed to the protective sleeve 3, the outer wall of the push bar 404 is fixed with a first spring 406, the end of the first spring 406 away from the push bar 404 is fixed to the outer wall of the support foot 201, and the inner wall of the storage slot 1 is fixed with a baffle 407 corresponding to the position of the first flip plate 402 and the second flip plate 403. During the process of the support frame 2 flipping from the vertical posture to the horizontal state, the connection between the first flip plate 402 and the second flip plate 403 can be pressed against the top surface of the baffle 407;

[0048] By moving the assembly 4 and the protective sleeve 3, the protective sleeve 3 can be automatically pushed to be sleeved on the end of the support leg 201 during the folding process of the support frame 2, so that in the folded state, the protective sleeve 3 can be sleeved around the end of the support leg 201, so that when the support frame is moved, the damage to people and foreign objects caused by the end of the support leg 201 hitting people and foreign objects can be reduced, and the safety is greatly improved;

[0049] The working process of the moving component 4 is as follows: during the flipping process of the support frame 2, when the support frame 2 flips to a tilted state tending to be horizontal, the connection between the first flip plate 402 and the second flip plate 403 contacts the top surface of the baffle 407, and then the support frame 2 continues to flip until it is horizontal, and is blocked by the baffle 407, pushing the first flip plate 402 and the second flip plate 403 to flip, thereby causing the push bar 404 to slide, pushing the protective cover 3 to slide on the outside of the support leg 201 to the end of the support leg 201, until the end of the support leg 201 is located on the inside of the protective cover 3, and in the subsequent movement and transportation process, since the end of the support leg 201 is wrapped by the protective cover 3, it can reduce the damage to the human body and foreign objects caused by the support leg 201 hitting foreign objects and the human body during transportation;

[0050] When the support frame 2 is flipped again to be flipped to a vertical position, due to the loss of the blocking of the baffle plate 407, the push bar 404 can be pulled under the action of the rebound force of the first spring 406 to make the protective cover 3 slide back to its original position, and the first flip plate 402 and the second flip plate 403 are also flipped back to their original positions, thereby exposing the end of the support leg 201, so that the support leg 201 can be inserted into the soil for stable support and placement;

[0051] The movable assembly 4 can be mechanically linked with the folding action of the entire bracket, and there is no need to manually move the protective cover 3. The movement of the protective cover 3 is completed synchronously during the folding process, which greatly reduces the manual operation steps and is more convenient to use.

[0052] The moving assembly 4 also includes a fixing assembly 408 installed on the pushing bar 404 to fix the position of the protective sleeve 3. The fixing assembly 408 includes a first threaded hole 4081 provided on the pushing bar 404. The inner wall of the first threaded hole 4081 is threadedly connected with a screw 4082. A positioning hole 4083 is provided at the lower end of the supporting foot 201. The screw 4082 cooperates with the positioning hole 4083.

[0053] When the entire bracket needs to be used indoors or on a hardened ground that cannot be damaged, the end of the support foot 201 is directly supported on the ground, which is easy to cause damage to the ground. In this case, before the entire bracket in the folded state is unfolded, the protective cover 3 can be sleeved on the end of the support foot 201 while the entire bracket is kept in the folded state. At this time, the screw 4082 is directly opposite to the positioning hole 4083. By rotating the four screws 4082 in sequence, the ends of the screws 4082 are inserted into the positioning holes 4083, thereby positioning the protective cover 3. When the entire bracket is subsequently unfolded, the rebound force of the first spring 406 cannot reset the protective cover 3. After the bracket is unfolded, the four protective covers 3 are supported on the ground, thereby preventing the sharp ends of the support foot 201 from causing damage to the ground.

[0054] A cover 6 is fixed on the outer wall of the lower end of the support leg 201, and the cover 6 covers both the push bar 404 and the first spring 406. The cover 6 is provided with an avoidance groove 601, and the end of the screw 4082 is located in the avoidance groove 601. The setting of the cover 6 can effectively protect the moving component 4;

[0055] The positioning assembly 5 includes a positioning box 501 which is symmetrically slidably connected to the two outer walls of the storage slot 1 on which the support frame 2 is installed, and a locking block 502 is slidably connected to the inner wall of the positioning box 501, one end of the locking block 502 passes through the positioning box 501 and extends to the outer side of the positioning box 501, and the end of the locking block 502 located on the outer side of the positioning box 501 is arranged in an inclined shape, and a second spring 503 is sleeved on the inner side of the positioning box 501, one end of the second spring 503 is pressed and contacted with the inner wall of the positioning box 501, and the other end of the second spring 503 is pressed and contacted with the outer wall of the locking block 502, a locking plate 504 is fixed to the side of the support foot 201 close to the locking block 502, and the locking block 502 cooperates with the locking plate 504, and a synchronous unlocking assembly 505 for driving the four locking blocks 502 to unlock is installed on the inner wall of the storage slot 1;

[0056] By operating the synchronous unlocking assembly 505, the two positioning boxes 501 on the same side are moved closer to each other, so that one end of the locking block 502 passing through the positioning box 501 is separated from the corresponding locking plate 504, thereby releasing the locking work of the support frame 2, and then the two support frames 2 can be folded, so that the two support frames 2 are folded, and there is no cable in the storage slot 1. After folding, the synchronous unlocking assembly 505 is operated again to reset the four positioning boxes 501, so that when the two support frames 2 are unfolded next time, the locking plate 504 is flipped to push the locking block 502 to be located on the inclined surface outside the positioning box 501, so that the locking block 502 slides and avoids until the support frame 2 is flipped to a vertical state. At this time, the inner side of the lower end of the support frame 2 is pressed against the outer wall of the storage slot 1, and then the second spring 503 pushes the locking block 502 to clamp the locking plate 504 under the action of the rebound force, thereby completing the positioning and locking work of the support frame 2;

[0057] The synchronous unlocking component 505 includes a slide rail 5051 symmetrically fixed on the inner wall of the bottom of the storage slot 1, and the outer walls of the two slide rails 5051 are symmetrically slidably installed with connecting strips 5052. The side walls of the storage slot 1 are symmetrically provided with side slide grooves 5053. The two ends of the connecting strip 5052 respectively pass through the side slide grooves 5053 at both ends to the outside of the storage slot 1 and are fixed to the positioning box 501. The middle part of the storage slot 1 is rotatably connected with a bidirectional screw rod 5054 through a bearing. The two connecting strips 5052 are respectively threadedly connected to the two ends of the bidirectional screw rod 5054 through a second threaded hole, and a knob 5055 is fixed to one end of the bidirectional screw rod 5054.

[0058] The storage slot 1 is symmetrically fixed with winding columns 101 on the inner wall at the bottom, and the two connecting strips 5052 are fixed with a wire plate 50521 on the side close to each other. The storage slot 1 can be used to store cables. After the power distribution cabinet is disassembled, the cables can also be removed from the power distribution cabinet and placed in the storage slot 1. When placing, the cables are wound around the outside of the two winding columns 101.

[0059] When operating the synchronous unlocking component 505 to unlock, the two-way screw rod 5054 is driven to rotate by turning the knob 5055 so that the two connecting strips 5052 are close to each other, thereby making the two positioning boxes 501 on the same side close to each other, unlocking the support frame 2. When there is no cable stored in the storage slot 1, the knob 5055 is immediately turned in the opposite direction after the two support frames 2 are unlocked and folded to reset the positioning box 501. If there is a cable wound and stored in the storage slot 1, after unlocking and folding the support frame 2, the knob 5055 can be continued to be turned so that the two connecting strips 5052 continue to approach each other, so that the two abutment plates 50521 clamp the cable and confine the cable in the storage slot 1, thereby preventing the cables from being scattered during the subsequent movement, transportation and storage process, until the next time the support frame 2 needs to be unfolded, the knob 5055 is turned in the opposite direction so that the two connecting strips 5052 reach the two ends of the side slide slot 5053 respectively, so that the positioning work of the support frame 2 can continue.
