The placement rack 7 includes a center beam 71, a bottom beam 72, multiple groups of long support columns 73 and multiple groups of short support columns 74. The center beam 71 is fixedly connected to the front center position of the back plate 12, the bottom beam 72 is located directly below the center beam 71 and is fixed to the back plate 12, multiple groups of long support columns 73 are fixedly connected between the center beam 71 and the bottom beam 72, and multiple groups of short support columns 74 are fixedly connected between the bottom beam 72 and the box cover 1 located below 1, the left and right sides of the center beam 71 and the bottom beam 72 are equidistantly fixedly connected with multiple groups of main support frames 75, the outer side of the main support frame 75 is slidably connected to the auxiliary support frame 76, the end of the auxiliary support frame 76 away from the center beam 71 is fixedly connected to the connecting plate 761, the side of the connecting plate 761 away from the auxiliary support frame 76 is fixed to the auxiliary cabinet 4, the bottom of the center beam 71 is connected to a driving member 78, the driving member 78 includes a worm 781, the front side of the surface of the center beam 71 is penetrated by a through groove 711, the front side of the center beam 71 is provided with a side hole 712, and the side hole 712 is connected to the through groove 711, the middle of the lower surface of the center beam 71 is fixedly connected to the left and right sides, the worm The rod 781 is rotatably connected to the inside of the through groove 711, the front end of the worm 781 passes through the side hole 712 and the two are rotatably connected, the inside of the ear plate 713 is rotatably connected to the double-threaded rod 783, and the middle position of the outer side of the double-threaded rod 783 is fixedly connected to the worm gear 784, the worm gear 784 is located between the two groups of ear plates 713, and the worm gear 784 is engaged with the worm 781. The outer thread sleeve of the double-threaded rod 783 is provided with two groups of nut seats 785, and the two groups of nut seats 785 are respectively located on the left and right sides of the two groups of ear plates 713, and the upper end of the nut seat 785 is detachably connected to the connecting rod 77, and the end of the connecting rod 77 away from the nut seat 785 is fixed to the connecting plate 761.

[0036] This utility model can accommodate changing battery cabinet space requirements in different application scenarios. The specific adjustment method is: rotating the worm 781 drives the worm wheel 784 and its inner double-threaded rod 783 to rotate. At this time, the two sets of nut seats 785 drive the two sets of auxiliary cabinets 4 away from each other via the connecting rod 77, thereby increasing the actual storage space of the battery cabinet. During the adjustment process, the auxiliary cabinet 4 causes the auxiliary support frame 76 to slide relative to the main support frame 75. After adjustment, the auxiliary support frame 76 and the main support frame 75 can still provide a stable placement platform for the batteries.

[0037] Secondly, when placing batteries, you can first open the protective door 2 on the front side of the main cabinet 1 downward, and then open the cabinet door 42 of the auxiliary cabinet 4 to both sides, and then place the batteries in order on the upper end of the placement rack 7. The placement rack 7 is provided with two layers of battery storage space through the center beam 71 and the bottom beam 72, which maximizes the space utilization of the battery cabinet. In addition, the setting of the long support column 73 and the short support column 74 can ensure the stability of the structure of the bottom beam 72 and the center beam 71, providing a more stable storage space for the battery. The heat dissipation net 41 plays the role of ventilation and heat dissipation, ensuring that the battery can effectively discharge the heat generated during operation. The setting of the main universal wheel 3 allows the staff to move the entire battery cabinet conveniently.

[0038] Furthermore, the lock 21 includes two sets of shafts 211, which are respectively fixedly connected to the left and right sides of the upper end of the protective door 2. The outer sides of the shafts 211 are rotatably connected to hooks 212, and the left and right sides of the box cover 11 located above are fixedly connected to fixed rods 213 that cooperate with the hooks 212.

[0039] Specifically, to close the protective door 2, the operator simply rotates the hook 212 so that it hooks onto the outside of the fixing rod 213. The groove on the hook 212 engages with the fixing rod 213, locking the protective door 2 in the closed position. Conversely, to open the protective door 2, the operator simply rotates the hook 212 in the opposite direction to release the connection between the hook 212 and the fixing rod 213.

[0040] Furthermore, the protective door 2 is composed of two groups of square plates 22, and the two groups of square plates 22 are connected by hinges.

[0041] Specifically, the protective door 2 can adopt two groups of square plates 22 with a folding structure. When the protective door 2 is opened, the square plates 22 can fold with each other, so that the protective door 2 does not take up too much space when it is fully opened.

[0042] Furthermore, two groups of L-shaped plates 5 are fixed to the lower end of the auxiliary cabinet 4 away from the placement rack 7 by bolts, and the lower surface of the L-shaped plate 5 is fixedly connected to the auxiliary universal wheel 51.

[0043] Specifically, when the auxiliary cabinet 4 is unfolded, the auxiliary universal wheels 51 can support the auxiliary cabinet 4, thereby sharing the gravity of the auxiliary cabinet 4 and the batteries stored therein.

[0044] Furthermore, two sets of horizontal slide grooves 43 are opened on the upper surface of the sub-cabinet 4, and the sliding member 6 includes a fixed seat 61, which is fixedly connected to the inside of the box cover 11. The front and rear sides of the fixed seat 61 are rotatably connected with pulleys 62, and the pulleys 62 are slidably connected to the slide grooves 43.

[0045] Specifically, when the relative positions of the two sets of auxiliary cabinets 4 and the main cabinet 1 change, the upper and lower surfaces of the auxiliary cabinets 4 are in contact with the pulley 62. As the pulley 62 rolls in the slide groove 43, the movement of the auxiliary cabinets 4 becomes smoother and easier, effectively reducing the friction resistance during movement.

[0046] Furthermore, the front and rear sides of the main support frame 75 are rotatably connected to guide wheels 751 through short shafts, and the front and rear sides of the auxiliary support frame 76 are provided with guide grooves 762, and the guide wheels 751 are slidably connected to the guide grooves 762.

[0047] Specifically, when the relative positions of the two groups of auxiliary cabinets 4 and the main cabinet 1 change, the auxiliary support frame 76 connected to the auxiliary cabinet 4 will slide relative to the main support frame 75 connected to the main cabinet 1. During the sliding process, the guide wheel 751 rolls inside the guide groove 762, effectively reducing the friction between the main support frame 75 and the auxiliary support frame 76, making the movement smoother and more stable.

[0048] Furthermore, a knob 782 is fixedly connected to the front end of the worm 781 and located at the front side of the center beam 71 , and a hexagonal head 7821 is fixedly connected to the front side of the knob 782 .

[0049] Specifically, the knob 782 allows the operator to manipulate the worm 781 to rotate. When a large number of batteries are placed on the rack 7, greater force may be required to rotate the worm 781. If the manual knob 782 does not provide sufficient force or rotation is restricted, the operator can use a wrench to operate the hexagonal head 7821. The hexagonal head 7821 is designed to be used with a standard wrench, providing greater torque, thereby easily rotating the worm 781 and completing the required adjustment or operation.

[0050] Furthermore, an insert block 771 is fixedly connected to the side of the connecting rod 77 away from the connecting plate 761 , and a connecting seat 7851 is fixedly connected to the upper surface of the nut seat 785 . The insert block 771 is inserted into the interior of the connecting seat 7851 and fixed by a fixing bolt 7852 .

[0051] Specifically, the connecting base 7851 forms a secure connection with the insert 771 via the fixing bolts 7852, indirectly ensuring a secure connection between the connecting rod 77 and the nut base 785. To remove the auxiliary cabinet 4, simply unscrew the fixing bolts 7852, separate the insert 771 from the connecting base 7851, and then pull the auxiliary cabinet 4 sideways to completely remove it from the main cabinet 1.

[0052] Furthermore, both outer ends of the double-threaded rod 783 are fixed with limit rings 786 by bolts.

[0053] Specifically, the limiting ring 786 serves to limit the nut seat 785 , thereby preventing the nut seat 785 from sliding off the double-threaded rod 783 during the adjustment process.

[0054] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
