Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with stable transportation. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box), which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center; the distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits; they distribute the power of a circuit of the upper-level distribution equipment to the nearest load; this level of equipment should provide protection, monitoring and control for the load.

[0003] Distribution cabinets are generally assembled and transported to the site for installation. However, during the transportation of the distribution cabinet, the distribution cabinet will be bumped. The vibration caused by the bump will affect the lines and equipment components in the distribution cabinet, causing the screws at the wiring to loosen, thereby causing the equipment to fall off and resulting in the internal lines of the distribution cabinet to be blocked. Utility Model Content

[0004] The purpose of the utility model is to provide a distribution cabinet with stable transportation, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A stable distribution cabinet for transportation, comprising a distribution cabinet body and a shock-absorbing base arranged at the bottom end of the distribution cabinet body, the shock-absorbing base comprising a bottom plate, a support plate connected to the bottom end of the distribution cabinet body is arranged on the top of the bottom plate, a plurality of evenly distributed shock-absorbing seats are arranged between the support plate and the bottom plate, a plurality of evenly distributed first mounting frames are symmetrically arranged on both sides of the support plate, a fixed plate located on both sides of the distribution cabinet body is symmetrically arranged on the end surface of the top of the support plate, a protective plate that fits the outer side wall of the distribution cabinet body is arranged on the inner side of the fixed plate, a plurality of evenly distributed limit rods are slidably connected to the fixed plate, one end of the limit rod extends to be fixedly connected to the protective plate, and the other end of the limit rod extends to the outer side of the fixed plate where a limit disk is arranged;

[0007] Buffer grooves corresponding to the first mounting bracket are symmetrically provided on both sides of the top end surface of the bottom plate, a sliding rod is provided in the buffer groove, a driving block is slidably connected to the sliding rod, a second mounting bracket is provided on the top of the driving block, a second shock-absorbing spring is sleeved on the sliding rod on the outer side of the driving block, and a buffer pad is provided on the side of the driving block away from the second shock-absorbing spring.

[0008] As a preferred technical solution of the utility model, the shock-absorbing seat includes a shell with a hollow cylindrical structure, a load-bearing rod is slidably connected to the shell, the top of the load-bearing rod extends to the outside of the shell and is fixedly connected to the bottom end face of the support plate, the bottom end face of the load-bearing rod extends to the inner cavity of the shell and is fixedly connected to a pressure plate with a circular structure, at least four fixing rods are slidably connected to the pressure plate and are distributed around the load-bearing rod as the axis, the two ends of the fixing rod are respectively fixedly connected to the top end face and the bottom end face of the inner cavity of the shell, and a third shock-absorbing spring is sleeved on the outside of the fixed rod at the bottom of the pressure plate.

[0009] As a preferred technical solution of the utility model, one end of the third shock-absorbing spring is fixedly connected to the bottom end surface of the pressure plate, and the other end of the third shock-absorbing spring is fixedly connected to the bottom end surface of the inner cavity of the shell.

[0010] As a preferred technical solution of the utility model, a first shock-absorbing spring is sleeved on the outer side of the limiting rod between the protective plate and the fixed plate, one end of the first shock-absorbing spring is fixedly connected to the protective plate, and the other end of the first shock-absorbing spring is fixedly connected to the fixed plate.

[0011] As a preferred technical solution of the present utility model, a buffer rod is hingedly connected between the first mounting frame and the second mounting frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] During installation, the staff pulls the limit plate on one side of the shock-absorbing base outward to drive the limit rod and the protective plate to move outward, causing the first shock-absorbing spring to undergo elastic deformation, and then places the distribution cabinet body on the top of the support plate, and then releases the limit plate. Under the elastic action of the spring, the first shock-absorbing spring rebounds and drives the protective plate to reset, so that the protective plate clamps and fixes the distribution cabinet body. When vibration is generated due to bumps during transportation, the distribution cabinet body will transmit the vibration force it receives to the support plate, and the support plate will transmit the vibration force it receives to the load-bearing rod again. The load-bearing rod squeezes the third shock-absorbing spring through the pressure plate, causing the third shock-absorbing spring to undergo elastic deformation, thereby buffering the vibration and impact force. The squeezed third shock-absorbing spring drives the support plate When the plate moves downward, the buffer rod rotates and squeezes the second shock-absorbing spring through the driving block. The second shock-absorbing spring can further buffer and disperse the vibration force, which not only improves the shock-absorbing effect and stability, but also realizes double shock absorption of the distribution cabinet body, avoiding the situation that a single shock absorption will still cause damage to the internal lines and equipment components of the distribution cabinet body when the vibration is large, thereby extending the service life of the distribution cabinet body. At the same time, through the setting of the protective plates on both sides of the distribution cabinet body and the first shock-absorbing spring, the vibration force generated on the left and right of the distribution cabinet body during bumpy transportation can be further mitigated and offset, ensuring that the electrical component structure inside the distribution cabinet body is firmly installed and operates normally, further improving the practicality of the distribution cabinet.

[0022] Example

[0023] like Figure 1A distribution cabinet with stable transportation shown in the figure includes a distribution cabinet body 1 and a shock-absorbing base 2 arranged at the bottom end of the distribution cabinet body 1. Through the setting of the shock-absorbing base 2, double shock absorption of the distribution cabinet body 1 is achieved, the shock absorption effect and stability are improved, and the service life of the distribution cabinet body 1 is extended.

[0024] Combination Figure 2-4 The shock-absorbing base 2 shown in the figure comprises a bottom plate 201, a support plate 202 connected to the bottom end of the power distribution cabinet body 1 is provided on the top of the bottom plate 201, a plurality of evenly distributed shock-absorbing seats 203 are provided between the support plate 202 and the bottom plate 201, a plurality of evenly distributed first mounting frames 204 are symmetrically provided on both sides of the support plate 202, a fixing plate 205 located on both sides of the power distribution cabinet body 1 is symmetrically provided on the top end surface of the support plate 202, and a fixing plate 205 is provided on the inner side of the fixing plate 205 connected to the outer wall of the power distribution cabinet body 1 The protective plate 206 is fitted together, and a plurality of evenly distributed limit rods 207 are slidably connected to the fixed plate 205. One end of the limit rod 207 extends to be fixedly connected to the protective plate 206, and the other end of the limit rod 207 extends to the outside of the fixed plate 205, where a limit plate 208 is provided. The diameter of the limit plate 208 is larger than the diameter of the limit rod 207. Through the setting of the limit plate 208, the displacement of the limit rod 207 can be limited, and at the same time, it is prevented from detaching from the fixed plate 205 when the limit rod 207 is displaced left and right.

[0025] Buffer grooves 209 corresponding to the first mounting frames 204 are symmetrically opened on both sides of the top end surface of the bottom plate 201 , and sliding rods 210 are arranged in the buffer grooves 209 .

[0026] A further optimized solution is that a first shock-absorbing spring 220 is sleeved on the outer side of the limiting rod 207 between the protective plate 206 and the fixed plate 205, one end of the first shock-absorbing spring 220 is fixedly connected to the protective plate 206, and the other end of the first shock-absorbing spring 220 is fixedly connected to the fixed plate 205. By arranging the protective plate 206 and the first shock-absorbing spring 220 on both sides of the distribution cabinet body 1, the vibration force generated on the left and right of the distribution cabinet body 1 during bumpy transportation can be further mitigated and offset, thereby ensuring that the electrical component structure inside the distribution cabinet body 1 is firmly installed and operates normally.

[0027] like Figure 4 As shown, a driving block 211 is slidably connected to the sliding rod 210, a second mounting frame 212 is provided on the top of the driving block 211, a second shock-absorbing spring 213 is sleeved on the sliding rod 210 outside the driving block 211, and a buffer pad 214 is provided on the side of the driving block 211 away from the second shock-absorbing spring 213. The buffer pad 214 is provided to prevent the driving block 211 from colliding with the inner wall of the buffer groove 209 when the vibration is too large and reaches a limit value, thereby playing a role of preparatory buffering.

[0028] According to a further optimized solution, a buffer rod 221 is hingedly connected between the first mounting frame 204 and the second mounting frame 212 .

[0029] like Figure 5 The shock-absorbing seat 203 shown in the figure comprises a shell 215 with a hollow cylindrical structure, a load-bearing rod 216 is slidably connected to the shell 215, the top of the load-bearing rod 216 extends to the outside of the shell 215 and is fixedly connected to the bottom end face of the support plate 202, the bottom end face of the load-bearing rod 216 extends to the inner cavity of the shell 215 and is fixedly connected to a pressure plate 217 with a circular structure, at least four fixing rods 218 are slidably connected to the pressure plate 217 and are distributed around the load-bearing rod 216 as the axis, the two ends of the fixing rod 218 are respectively fixedly connected to the top end face and the bottom end face of the inner cavity of the shell 215, and a third shock-absorbing spring 219 is sleeved on the outside of the fixing rod 218 at the bottom of the pressure plate 217.

[0030] Furthermore, one end of the third shock absorbing spring 219 is fixedly connected to the bottom end surface of the pressure plate 217 , and the other end of the third shock absorbing spring 219 is fixedly connected to the bottom end surface of the inner cavity of the shell 215 .

[0031] The working principle of this utility model:

[0032] During installation, the staff pulls the limit plate 208 on one side of the shock-absorbing base 2 outward, thereby driving the limit rod 207 and the protective plate 206 to move outward, causing the first shock-absorbing spring 220 to undergo elastic deformation, and then places the distribution cabinet body 1 on the top of the support plate 202, and then releases the limit plate 208. Under the elastic action of the spring, the first shock-absorbing spring 220 rebounds and drives the protective plate 206 to reset, so that the protective plate 206 clamps and fixes the distribution cabinet body 1. When vibration is generated due to bumps during transportation, the distribution cabinet body 1 will transfer the vibration force it receives to the support plate 202, and the support plate 202 will transfer the vibration force it receives to the load-bearing rod 216 again. The load-bearing rod 216 squeezes the third shock-absorbing spring 219 through the pressure plate 217, causing the third shock-absorbing spring 219 to undergo elastic deformation, thereby buffering the vibration and impact force. While the shock-absorbing spring 219 is squeezed to drive the support plate 202 to move downward, the buffer rod 221 rotates and squeezes the second shock-absorbing spring 213 through the driving block 211. The second shock-absorbing spring 213 can further buffer and disperse the vibration force, which not only improves the shock-absorbing effect and stability, but also realizes double shock absorption of the distribution cabinet body 1, avoiding the situation that a single shock absorption will still cause damage to the internal lines and equipment components of the distribution cabinet body 1 when the vibration is large, thereby extending the service life of the distribution cabinet body 1. At the same time, through the setting of the protective plate 206 and the first shock-absorbing spring 220 on both sides of the distribution cabinet body 1, the vibration force generated by the distribution cabinet body 1 on the left and right during transportation bumps can be further mitigated and offset, ensuring that the electrical component structure inside the distribution cabinet body 1 is firmly installed and operates normally, thereby further improving the practicality of the distribution cabinet.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
