Description

Technical Field

[0001] The utility model relates to the field of power supply cabinets, in particular to a UPS power supply cabinet with adjustable height. Background Art

[0002] UPS, or uninterruptible power supply, is an uninterruptible power supply containing an energy storage device, which is mainly used to provide uninterruptible power supply to some equipment with high requirements for power supply stability. In the Chinese utility model patent with announcement number CN219535702U, a UPS power supply that is easy to adjust is disclosed, including a body of a UPS power supply and an adjustment component for adjusting the height of the body. The body is supported by multiple support rods and a support frame. The first spring can support the support rod upward, and the screw rod can drive the driving block to move up and down. The driving block can drive the body to move up and down through the sliding plate, which is convenient for adjusting the height of the body. In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the above structure, when adjusting the height, it is necessary to rotate two screw rods synchronously. Since the screw rods are arranged on the left and right sides of the power cabinet, two people are required to do it. When the two screw rods are rotated in sequence, the left and right sides of the power cabinet will be tilted, and the whole body is supported by a spring. The spring may fail after a long period of compression, causing the power cabinet to fall. For this reason, we designed a UPS power cabinet with adjustable height. Utility Model Content

[0003] In order to solve the technical problem that two persons are required to synchronously rotate two screw rods when adjusting the height, the utility model provides a UPS power cabinet with adjustable height.

[0004] The utility model is implemented by the following technical scheme: a UPS power cabinet with adjustable height, comprising a placement plate, wherein four corners of the bottom end of the placement plate are respectively provided with a universal wheel, and the upper end surface of the placement plate is provided with two groups of symmetrically arranged lifting mechanisms, a ball screw is installed between the two lifting mechanisms, and the upper end of the lifting mechanism is rotatably connected to the bottom of the cabinet.

[0005] As a further improvement of the above scheme, the lifting mechanism includes two upper plates, the upper parts of the two upper plates are rotatably mounted on the bottom of the cabinet through shaft plates and shaft pins, and the end of the upper plate away from the cabinet is rotatably mounted with a lower plate through a shaft pin, the lower end of the lower plate is rotatably mounted above the placement plate, and a nut seat is rotatably mounted between the upper ends of the two lower plates, and rotating the ball screw can make the two nut seats move inward or outward at the same time, thereby making the lower plate and the upper plate unfold or fold, so that the cabinet can be lifted and lowered as needed.

[0006] As a further improvement of the above-mentioned solution, a fixing plate is welded on both sides of the left and right sides of the upper surface of the placing plate, a lifting hole is penetrated through the fixing plate, a bearing seat is provided in the lifting hole for sliding up and down, and the ball screw is rotatably installed between the two bearing seats, which can guide the ball screw and make its operation more stable.

[0007] As a further improvement of the above scheme, the nut seat is connected to the ball screw, and the nut seat is composed of a nut, a steel ball, a pre-compression sheet, a deflector, and a dust collector. The left and right ends of the ball screw have opposite spiral directions, and the rotation of the ball screw can make the two nut seats move inward or outward at the same time.

[0008] The left and right ends of the ball screw are passed through the fixing plate and placed outside thereof, and threaded sections are provided at both ends of the ball screw, and fixing nuts are threadedly connected to the threaded sections. An insertion hole is also provided at the left end of the ball screw, and the ball screw can be rotated by inserting a straight rod into the insertion hole. After the rotation is completed, the straight rod is held so that the ball screw cannot rotate, and then the fixing nut can be rotated, so that the fixing nut fixes the ball screw and prevents it from rotating when not needed, thereby improving safety.

[0009] As a further improvement of the above solution, a guide bracket is installed at each of the four corners of the upper surface of the placement plate, and adjustment sliding holes are formed through the left and right sides of the guide bracket, and the guide bracket is an L-shaped structure;

[0010] The lower part of the outer surface of the cabinet is in sliding contact with the inner wall of the guide bracket, and locking screws are provided on the left and right sides of the cabinet. The locking screws pass through the adjusting slide hole and are placed on the outside thereof and are threadedly connected with locking nuts, which can guide the lifting and lowering of the cabinet and can fix the four corners of the cabinet to make it more stable after lifting and lowering.

[0011] As a further improvement of the above scheme, a support pad is welded to the bottom end of each guide bracket, and the support pad is fixed to the placement plate by screws. The height of the support pad is greater than the height of the lifting mechanism after folding, and can support the movement of the cabinet so that it will not interfere with the lifting mechanism when it is at the lowest end.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides a lifting mechanism above the placement plate, and installs the cabinet above the lifting mechanism.

A ball screw 7 is installed between the two lifting mechanisms 4, and the upper end of the lifting mechanism 4 is rotatably connected to the bottom of the cabinet 1.

[0024] The lifting mechanism 4 includes two upper plates 42, the upper parts of the two upper plates 42 are rotatably mounted on the bottom of the cabinet 1 through shaft plates and shaft pins, and the end of the upper plate 42 away from the cabinet 1 is rotatably mounted with a lower plate 41 through a shaft pin, the lower end of the lower plate 41 is rotatably mounted above the placement plate 2, and a nut seat 43 is rotatably mounted between the upper ends of the two lower plates 41, and rotating the ball screw 7 can make the two nut seats 43 move inward or outward at the same time, thereby making the lower plate 41 and the upper plate 42 unfold or fold, so that the cabinet 1 can be lifted and lowered as needed.

[0025] A fixing plate 6 is welded on both sides of the left and right sides of the upper end surface of the placing plate 2. A lifting hole 61 is penetrated through the fixing plate 6. A bearing seat is set in the lifting hole 61 for sliding up and down. The ball screw 7 is rotatably installed between the two bearing seats, which can guide the ball screw 7 and make its operation more stable.

[0026] The nut seat 43 is connected to the ball screw 7. The nut seat 43 is composed of a nut, a steel ball, a pre-compression sheet, a reverser, and a dust collector. The left and right ends of the ball screw 7 have opposite spiral directions. The rotation of the ball screw 7 can make the two nut seats 43 move inward or outward at the same time.

[0027] The left and right ends of the ball screw 7 pass through the fixing plate 6 and are placed outside it. Both ends of the ball screw 7 are provided with threaded sections 71, and fixing nuts 72 are threadedly connected to the threaded sections 71. A socket is also provided at the left end of the ball screw 7. The ball screw 7 can be rotated by inserting a straight rod into the socket. After the rotation is completed, the straight rod is held so that the ball screw 7 cannot rotate, and then the fixing nut 72 can be rotated so that the fixing nut 72 fixes the ball screw 7 so that it will not rotate when not needed, thereby improving safety.

[0028] A guide bracket 5 is installed at each of the four corners of the upper surface of the placement plate 2. Adjustment sliding holes 51 are formed through the left and right sides of the guide bracket 5, and the guide bracket 5 is an L-shaped structure.

[0029] The lower part of the outer surface of the cabinet 1 is in sliding contact with the inner wall of the guide bracket 5, and locking screws 52 are provided on the left and right sides of the cabinet 1. The locking screws 52 pass through the adjusting slide hole 51 and are placed on the outside thereof and are threadedly connected with locking nuts. They can guide the lifting and lowering of the cabinet 1 and can fix the four corners of the cabinet 1 to make it more stable after lifting and lowering.

[0030] A support pad 53 is welded to the bottom end of each guide bracket 5, and the support pad 53 is fixed to the placement plate 2 by screws. The height of the support pad 53 is greater than the height of the lifting mechanism 4 after folding, and can support the movement of the cabinet 1 so that it will not interfere with the lifting mechanism 4 when it is at the lowest end.

[0031] The implementation principle of a UPS power cabinet with adjustable height in the embodiment of the present application is as follows: when adjusting the height of the cabinet body 1, a wrench is used to loosen the fixing nuts 72 at the left and right ends of the ball screw 7, and the locking nuts on the multiple locking screws 52 are loosened, and then a straight rod can be inserted into the insertion hole of the ball screw 7, and then the ball screw 7 is rotated clockwise or counterclockwise. Since the ball screw 7 is connected to the nut seat 43, and the left and right ends of the ball screw 7 have opposite spiral directions, this can make the two nut seats 43 moves inward or outward at the same time, so that the lower plate 41 and the upper plate 42 can be unfolded or folded, so that the cabinet 1 can be raised or lowered as needed. When the cabinet 1 is at the required height, the four locking nuts are screwed onto the locking screws 52 in sequence, and then the straight rod is held so that the ball screw 7 cannot rotate, and then the fixing nut 72 can be rotated so that the fixing nut 72 fixes the ball screw 7. In this way, the height of the cabinet 1 will not change due to the rotation of the ball screw 7 due to misoperation in the later stage, thereby improving safety;

[0032] By arranging a lifting mechanism 4 above the placement plate 2 and installing the cabinet 1 above the lifting mechanism 4, the cabinet 1 can be at a desired appropriate height as required, and cooperate with the guide brackets 5 arranged around it, so that the lifting of the cabinet 1 is more stable, and the overall operation is convenient, and one person can operate it;

[0033] By setting fixing nuts 72 at both ends of the ball screw 7, it is possible to prevent the ball screw 7 from rotating due to operation and causing the height of the cabinet 1 to change. The multiple locking screws 52 and locking nuts set together can further support the cabinet 1 and improve its firmness.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
