[0015] 1. The invention controls the rising of the supporting leg through the transmission assembly, drives the first hinged rod and the second hinged rod to rotate, and drives the supporting rod to move when the first hinged rod and the second hinged rod rotate. The supporting rods move away from each other so that the clamping rod fits with the wire management rack, clamps the wires and fixes them, so that the wires can be combed and fixed before moving, avoiding the wires from being entangled and knotted due to vibration during movement. The movement of the supporting rod drives the connecting rod to move, and at the same time drives the third hinged rod to rotate, and drives the mounting plate to shrink and fold through the third hinged rod, so as to avoid the stretching of the outer part of the mounting plate during movement, which affects the movement.

[0016] 2. The invention drives the T-shaped support plate to slide upward by the rising connecting rod.

At the same time, the clamping block drives the trapezoidal extrusion plate to push the L-shaped extrusion rod to slide downward, pushing the gate of the power-off switch downward to cut off the power, thereby preventing the electrical components from continuing to work while moving, or causing short circuits and the like, causing accidents.

[0017] 3. The invention causes the slider to slide by moving the clamping block. When the slider slides, the groove on the inner wall fits with the protrusion, thereby driving the protrusion to slide in the slide groove. The sliding of the protrusion drives the rotating rod to rotate along the slide groove, further driving the gear to rotate.

The support leg 111 passes through the bottom surface of the power distribution cabinet body 1, and is slidably connected at the penetration point. By starting the transmission component 6, the transmission component 6 rotates to drive a series of components such as bevel gears and threaded rods to drive the support leg 111 to slide up and down. When the support leg 111 slides upward to the highest point, the power distribution cabinet body 1 is supported by the universal wheel 5, making the power distribution cabinet body 1 more convenient to carry and move. When the support leg 111 slides downward to the lowest point, the power distribution cabinet body 1 is supported by the support leg 111. To prevent the power distribution cabinet body 1 from sliding during use, one end of the first hinged rod 112 is hinged to the upper surface of the support leg 111, and the support leg 111 slides up and down to drive the first hinged rod 112 to move up and down and rotate at the same time, and the other end of the first hinged rod 112 is hinged to the second hinged rod 113, and the rotation of the first hinged rod 112 drives the second hinged rod 113 to rotate, and the second hinged rod 113 is hinged to the front of the placement plate 3 away from one end of the first hinged rod 112, and the support rod 114 passes through the hinge point of the first hinged rod 112 and the second hinged rod 113, and the penetration point is rotatably connected. When the second hinged rod 113 rotates, the angle between the first hinged rod 112 and the second hinged rod 113 changes, driving the two groups of support rods 114 to move away from or close to each other.A first cable management rack 115 and a second cable management rack 116 are fixed to the side wall of the support rod 114. The second cable management rack 116 runs through the first cable management rack 115 and is slidably connected at the penetration point. The movement of the support rod 114 drives the first cable management rack 115 and the second cable management rack 116 to extend and retract. A clamping rod 117 is hinged on the side wall of the support rod 114. The two groups of clamping rods 117 are hinged to each other at one end away from the support rod 114. The movement of the support rod 114 drives the clamping rod 117 to fit or move away from the cable management rack. A connecting rod 118 is fixed to the rear end of the support rod 114. When the support rod 114 moves, it drives the connecting rod 118 to move together. The end of the connecting rod 118 away from the support rod 114 is hinged to a third hinged rod 119. The two groups of third hinged rods 119 are hinged to each other at one end away from the connecting rod 118. When the connecting rod 118 moves, it drives the third hinged rod 119 rotates, and the two sets of third hinged rods 119 drive the hinge point to move when they rotate. The hinged parts of the two sets of third hinged rods 119 are penetrated by hinged blocks 1110, and the penetration parts are rotatably connected. The third hinged rod 119 drives the hinged blocks 1110 to move. The side walls of the hinged blocks 1110 are slidably connected to the front of the mounting plate 8. When the hinged blocks 1110 move, they drive the mounting plate 8 to move and expand or contract. The fixing device 11 can control the support legs 111 to rise through the transmission assembly 6 when it is necessary to move, so that the clamping rod 117 fits with the wire management rack to clamp and fix the wires, so that the wires can be combed and fixed before moving, to prevent the wires from being entangled and knotted due to vibration during movement, and the mounting plate 8 is driven to shrink and fold through the third hinged rod 119 to prevent the outer part of the mounting plate 8 from stretching during movement and affecting movement.

[0029] When this embodiment works: when the motor is started, the motor drives the transmission rod to rotate, the rotation of the transmission rod drives the first bevel gear to rotate, the rotation of the first bevel gear drives the second bevel gear to rotate, and the rotation of the second bevel gear drives the threaded rod to rotate, so that the threaded rod can drive the support leg 111 to adjust the up and down position. As the support leg 111 moves up and down, the first hinged rod 112 connected to it will not only move up and down with the up and down movement of the support leg 111, but also rotate at the same time due to the connection and constraint relationship between it, the support leg 111 and other components. The rotation of the first hinged rod 112 will transmit the force to the second hinged rod 113 through the connection between it and the second hinged rod 113, thereby driving The second hinge rod 113 is driven to rotate, and during the rotation of the second hinge rod 113, due to the relative movement between the first hinge rod 112 and the second hinge rod 113, the angle between the first hinge rod 112 and the second hinge rod 113 will change. The change of the angle will cause the two groups of support rods 114 respectively connected to the first hinge rod 112 and the second hinge rod 113 to move away from or close to each other. When the two groups of support rods 114 move away from each other, since the first cable organizer 115 and the second cable organizer 116 are respectively connected to the two groups of support rods 114, the first cable organizer 115 and the second cable organizer 116 connected thereto will also move away from each other, thereby achieving a stretching effect. The clamping rod 117 will also rotate in this process due to the connection and force relationship between it and the relevant components, and rotate to a position close to the cable management rack. At this time, the two groups of support rods 114 will move away from each other, which will also cause the two groups of connecting rods 118 to move away from each other. The mutual movement of the two groups of connecting rods 118 will drive the angle between the third hinged rods 119 to increase. As the angle increases, the hinge points of the two groups of third hinged rods 119 will move due to their geometric structure and force conditions. The movement of the hinge points will drive the hinge blocks 1110 connected thereto to move, and the movement of the hinge blocks 1110 will pull the mounting plate 8, so that the mounting plate 8 is close to the power distribution cabinet body 1. In this process, the shock-absorbing spring 7 will Because the mounting plate 8 is compressed due to its approaching movement, conversely, when the two groups of support rods 114 approach each other, the first cable management rack 115 and the second cable management rack 116 will approach each other and shrink due to their connection relationship with the support rods 114, and the clamping rod 117 will rotate to a position away from the cable management rack due to the action of the relevant connecting force, and the two groups of support rods 114 approaching each other will cause the two groups of connecting rods 118 to approach each other, and the two groups of connecting rods 118 approaching each other will drive the angle between the third hinge rod 119 to become smaller, and the movement of the hinge points of the two groups of third hinge rods 119 will drive the hinge block 1110 to move, and at the same time, the shock-absorbing spring 7 will exert elastic force on the mounting plate 8 due to its own elastic characteristics, so that the mounting plate 8 is unfolded again.

[0030] See also Figure 1-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, the protective device 12 includes a T-shaped support plate 121, a clamping block 122, a reset spring 123, a trapezoidal extrusion plate 124 and an L-shaped extrusion rod 125. The T-shaped support plate 121 penetrates the placement plate 3 and is slidably connected at the penetration point. The bottom surface of the T-shaped support plate 121 is slidably connected to the upper surface of the connecting rod 118. The movement of the connecting rod 118 drives the T-shaped support plate 121 to slide up and down. The upper surface of the T-shaped support plate 121 slides with a clamping block 122. When the T-shaped support plate 121 slides upward, the clamping block 122 is pushed to clamp and fix the electrical component 4. The side wall of the clamping block 122 is fixed with a reset spring 123. When the clamping block 122 slides, the reset spring 123 is stretched. The end of the reset spring 123 away from the clamping block 122 is fixedly connected to the inner wall of the power distribution cabinet body 1. When the T-shaped support plate 121 slides downward, the clamping block 122 is clamped. The tension of the reset spring 123 is reset, and a trapezoidal extrusion plate 124 is fixed to the side wall of the clamping block 122 away from the reset spring 123. When the clamping block 122 slides toward the electrical component 4, the trapezoidal extrusion plate 124 is driven to move together. An L-shaped extrusion rod 125 is sliding on the front of the electrical component 4. The upper surface of the L-shaped extrusion rod 125 is slidably connected to the inclined surface of the trapezoidal extrusion plate 124. When the trapezoidal extrusion plate 124 moves, the L-shaped extrusion rod 125 is driven to slide. When the power supply distribution cabinet body 1 needs to be moved, the protective device 12 can drive the connecting rod 118 to rise by retracting the supporting leg 111, and push the clamping block 122 to clamp the electrical component 4 to prevent the electrical component 4 from shaking too much during movement and causing damage. At the same time, the clamping block 122 drives the trapezoidal extrusion plate 124 to push the L-shaped extrusion rod 125 to slide downward, and pushes the gate of the power-off switch 9 downward to cut off the power, to prevent the electrical component 4 from continuing to work during movement and causing accidents.

[0031] In addition, the power supply distribution cabinet body 1 is provided with a shielding device 13 for closing the heat dissipation hole 10 when moving. The shielding device 13 includes a slider 131, a rotating rod 132, a gear 133, a saw blade 136 and a baffle 137. The slider 131 is fixedly connected to the upper surface of the clamping block 122. When the clamping block 122 is moved, the slider 131 can be driven to move. The slider 131 is penetrated by a rotating rod 132, and the penetration is threaded. When the slider 131 moves, the rotating rod 132 is driven to rotate. The rotating rod 132 penetrates the side wall of the power supply distribution cabinet body 1 and is rotatably connected at the penetration. A gear 133 is fixed to the side end of the rotating rod 132. When the rotating rod 132 rotates, it drives the gear 133 to rotate. A sliding groove 134 is provided on the outer wall of the rotating rod 132, and a groove is provided on the inner wall of the slider 131. A protrusion 135 is slidably provided on the inner wall of the sliding groove 134. The protrusion 135 and the groove of the slider 131 The inner wall fits together, and when the slider 131 slides, it drives the protrusion 135 to slide. When the protrusion 135 slides on the inner wall of the slide groove 134, it drives the rotating rod 132 to rotate along with the slide groove 134. A saw blade 136 slides on the outer wall of the power supply distribution cabinet body 1. The saw blade 136 is meshed with the gear 133. When the gear 133 rotates, it drives the saw blade 136 to slide up and down. A baffle 137 is fixed to the bottom of the saw blade 136. The saw blade 136 slides up and down, driving the baffle 137 to move up and down; when the shielding device 13 needs to move, the clamping block 122 driven by the support leg 111 can be retracted to drive the slider 131 to drive the rotating rod 132 to rotate, and further drive the gear 133 to rotate, so that the saw blade 136 drives the baffle 137 to move downward, and the heat dissipation hole 10 is covered, so as to avoid too much dust from entering the heat dissipation hole 10 when the power supply distribution cabinet body 1 moves, thereby affecting the subsequent use effect of the heat dissipation hole 10.

[0032] When the present embodiment is working, as the supporting legs 111 move upward, the connecting rod 118 moves upward, so that the connecting rod 118 can squeeze the T-shaped supporting plate 121 and slide upward along the corresponding slideway. The upward sliding action of the T-shaped supporting plate 121 will exert a thrust on the inclined surface of the clamping block 122, causing the clamping blocks 122 to approach each other. In this case, the return spring 123 connected between the clamping blocks 122 will be stretched. With the help of the action process of the clamping blocks 122 approaching each other, the The effect and function of clamping and fixing the paired electrical components 4 is that at the same time when the clamping block 122 moves, it will drive the trapezoidal extrusion plates 124 connected to it to move towards each other synchronously. The movement of the trapezoidal extrusion plates 124 approaching each other will have an effect on the L-shaped extrusion rod 125, causing the L-shaped extrusion rod 125 to slide downward along a pre-set track. When the L-shaped extrusion rod 125 contacts the power-off switch 9, it will push the gate downward, thereby achieving the purpose of cutting off the power supply of the electrical components 4.

[0033] The movement of the clamping block 122 will also cause the slider 131 to slide, and the sliding movement of the slider 131 will drive the protrusion 135 to slide in the slide groove 134, causing the rotating rod 132 to rotate, and the rotation of the rotating rod 132 will further drive the gear 133 to rotate, and the gear 133 will drive the saw blade 136 to slide downward, and when the saw blade 136 slides downward, it will drive the baffle 137 to move downward together, so as to achieve the effect of covering the heat dissipation hole 10, and when the connecting rod 118 moves downward, the T-shaped support plate 121 will slide downward under the influence of gravity, and the clamping block 122 will be reset. Under the pulling force of the spring 123, it will return to its initial position. The resetting action of the clamping block 122 will drive the trapezoidal extrusion plates 124 to move away from each other. The mutual movement of the trapezoidal extrusion plates 124 will cause the L-shaped extrusion rod 125 to slide upward. At the same time, during the resetting process of the clamping block 122, the slider 131 will also be driven to slide. The sliding of the slider 131 drives the rotating rod 132 to rotate. The rotation of the rotating rod 132 drives the gear 133 to rotate. The rotation of the gear 133 drives the saw blade 136 to slide upward. The upward sliding of the saw blade 136 will drive the baffle 137 to move upward, thereby finally exposing the heat dissipation hole 10 for heat dissipation.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
