Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: a high-density distribution box with adjustable height, comprising a distribution box body 1, a bottom plate 2 is welded and fixed at the bottom of the distribution box body 1, a base 3 is arranged at the bottom of the base plate 2, the area of ​​the base 3 is larger than the area of ​​the base plate 2, and the four corners of the base 3 are provided with positioning shafts 4 which are slidably connected with the four corners of the base plate 2, the bottom end of the positioning shaft 4 is welded and fixed to the bottom of the base 3, an adjusting plate 5 is connected between the corresponding sides of the positioning shaft 4, the inner side of the adjusting plate 5 is fixedly connected to the outer wall of the distribution box body 1 through a connecting piece, both sides of the adjusting plate 5 are movably sleeved on the outside of the positioning shaft 4 through a connecting sleeve 6, and the rear side of the distribution box body 1 is provided with a connecting plate 7 which is connected to a group of rear sides of the connecting sleeve 6, and the connection between the two sides of the connecting plate 7 and the connecting sleeve 6 can also A welding fixed connection method is adopted, and a screw rod 15 is provided on one side of the outside of the distribution box body 1. The screw rod 15 is inserted into the middle of one of the adjustment plates 5 through a threaded structure, and the bottom end of the screw rod 15 is connected to the top of the base 3 through a bearing. A through hole matching the screw rod 15 is provided on the bottom plate 2, and a linkage mechanism for driving the screw rod 15 to rotate is provided on one side of the top of the base 3. When the distribution box body 1 of this structure needs to be adjusted at the height of the top of the base 3 during maintenance, the linkage mechanism on one side of the top of the base 3 can drive the screw rod 15 to rotate. When the screw rod 15 rotates, the corresponding adjustment plate 5 can be driven to move up and down through the threaded structure. The up and down movement of the adjustment plate 5 will drive the sleeves 6 on both sides to slide along the outside of the positioning shaft 4. At this time, the up and down sliding A set of connecting sleeves 6 can drive another set of adjusting plates 5 to move up and down under the action of the connecting plate 7. When the two sets of adjusting plates 5 move up and down at the same time, the overall height of the distribution box body 1 can be quickly adjusted, which is easier to operate and more efficient to adjust. This avoids the problem that most of the existing distribution box bodies 1 adjust the height by adjusting the four supporting legs, which is not only very troublesome and inefficient, but also prone to tilting and tipping, thereby making the adjustment process of the distribution box body 1 more stable. The linkage mechanism includes a motor 8, a first pulley 9 and a second pulley 14. The motor 8 is fixedly mounted on one side of the top of the base 3. A protective shell is provided on the outside of the motor 8. The first pulley 9 is fixedly sleeved on the output shaft of the motor 8, and the second pulley 14 is fixedly sleeved on the screw rod 15. On the outside of the bottom end, a belt is connected between the first pulley 9 and the second pulley 14. When the motor 8 of this structure is driven, the first pulley 9 can be directly driven to rotate through the output shaft. When the first pulley 9 rotates, the second pulley 14 can be driven to rotate through the belt transmission. When the second pulley 14 rotates, it can realize the function of driving the screw rod 15 to rotate, so as to realize the lifting and lowering of the adjustment plate 5. The four corners of the bottom of the bottom plate 2 are movably provided with a turn buckle 10. The top of the inner end of the turn buckle 10 is connected to the bottom of the bottom plate 2 through a turn pin, and the outer end of the turn buckle 10 is provided with a notch that matches the structure of the positioning shaft 4. A magnetic sheet is bonded and fixed to the inner wall of the notch at the outer end of the turn buckle 10. When the distribution box body 1 of this structure is adjusted to a suitable height at the top of the base 3,The turn buckle 10 can be rotated at the bottom of the bottom plate 2 and engaged in the corresponding position of the positioning shaft 4 and adsorbed by the magnetic sheet to achieve the function of reinforcing the bottom of the connection between the bottom plate 2 and the positioning shaft 4, thereby ensuring the stability of the distribution box body 1 after the height is adjusted. A receiving groove 11 is provided in the middle of the bottom of the bottom plate 2, and the interior of the receiving groove 11 is symmetrically and movably provided with a support column 13 of a telescopic structure. The inner ends of the support columns 13 are rotatably connected to the inner walls of both sides of the receiving groove 11 through a turn pin. When the distribution box body 1 of this structure is adjusted to a suitable height at the top of the base 3, the support column 13 can be turned out inside the receiving groove 11 and adjusted to a suitable length to be supported on the top of the base 3, so that the distribution box body 1 can be adjusted to a suitable height at the top of the base 3. To further ensure the stability of the distribution box body 1 after the height is adjusted, buckles 12 are provided on both sides of the inner wall of the top of the groove 11. The buckles 12 are arc-shaped and made of elastic metal. The buckles 12 match the structure of the support column 13. When the support column 13 of this structure is recovered to the inside of the groove 11, it can be engaged by the buckles 12 to quickly limit and fix it to prevent the support column 13 from flipping out of the inside of the groove 11. The positioning shaft 4 is vertically distributed on the top of the base 3, and the top of the positioning shaft 4 is fixed with a rubber sleeve. The positioning shaft 4 of this structure can ensure the range of height adjustment of the distribution box body 1, and the rubber sleeve at the top of the positioning shaft 4 can protect the top of the positioning shaft 4.

[0019] Working principle: When using the height-adjustable high-density distribution box, first, when the height of the distribution box body 1 at the top of the base 3 needs to be adjusted during maintenance, start the motor 8. When the motor 8 is driven, it can directly drive the first pulley 9 to rotate through the output shaft. When the first pulley 9 rotates, it drives the second pulley 14 to rotate through the belt transmission. When the second pulley 14 rotates, it will synchronously drive the screw rod 15 to rotate. When the screw rod 15 rotates, it drives the corresponding adjustment plate 5 to move up and down through the threaded structure. The up and down movement of the adjustment plate 5 will drive the connecting sleeves 6 on both sides to slide along the outside of the positioning shaft 4. At this time, the connecting plate 7 will be driven by the linkage of the connecting sleeve 6 to drive another set of adjustment plates 5 to move up and down, and the two sets of adjustment plates 5 move up and down at the same time. When it is active, the overall height of the distribution box body 1 can be quickly adjusted. When the distribution box body 1 is adjusted to a suitable height on the top of the base 3, the four turn buckles 10 are rotated respectively. The turn buckle 10 can engage the notch at the outer end with the corresponding position of the positioning axis 4 and absorb it with a magnetic sheet. In this way, the four corners of the bottom plate 2 can stay more firmly at the corresponding positions on the positioning axis 4. At the same time, the operator can flip out the support column 13 inside the groove 11 and adjust it to a suitable length to support it on the top of the base 3 to ensure the stability of the distribution box body 1 after the height is adjusted. When the support column 13 is not needed, the support column 13 is recovered to the inside of the groove 11 and engaged with the buckle 12, thereby completing a series of work.
