Abstract
Description
Technical Field
[0001] This invention relates to the field of fixed installation technology, and more specifically, to a compatible fixed installation device and a power distribution device including the device. Background Technology
[0002] Various electrical modules (such as batteries and power distribution modules) are widely used in power systems, communication base stations, uninterruptible power supplies (UPS) and various power distribution equipment. Electrical modules of different specifications and sizes have different dimensions in the length, width and height, so appropriate fixing devices are needed to reliably install them inside the equipment or in the cabinet.
[0003] Currently, traditional fixing methods mainly suffer from the following problems: First, poor versatility. Traditional fixing devices usually adopt fixed-size limiting or clamping structures. One type of fixing device can only be adapted to electrical modules of a specific size. Different sizes of electrical modules often require custom-made special accessories, resulting in a wide variety of fixing devices and difficulties in management. Second, limited adjustment dimensions. Some existing adjustable fixing devices only have the ability to adjust in one dimension, such as only adjusting the width or only adjusting the height. They cannot simultaneously adapt to changes in the length, width, and height of electrical modules, making it difficult to achieve truly universal fixing. Summary of the Invention
[0004] The purpose of this invention is to provide a compatible fixing device and a power distribution device using the same, so as to solve the problems of poor versatility and limited adjustment dimensions of existing fixing devices.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] In a first aspect, the present invention provides a compatible fixing device, comprising: a base; two side baffles, mounted on the base opposite to each other, forming a receiving space for accommodating the fixed component, and the distance between the two side baffles being adjustable; a top pressure plate, which is arranged in the left-right direction and has an adjustable length, with its left and right ends respectively connected to the corresponding side baffles, and the side baffles and the top pressure plate being connected by a height-adjustable connecting structure so that the height of the top pressure plate is adjustable; and a front and rear limiting structure, disposed on the base, for limiting the fixed component in the front and rear direction.
[0007] Preferably, the height-adjustable connection structure includes at least two first locking holes spaced apart along the height direction on the side baffle, and a first locking hook disposed on the top pressure plate, wherein the first locking hook is hooked into the first locking hole.
[0008] Preferably, the top pressure plate has connecting plates extending downward at both ends and adapted to abut against the side of the side baffle, and the first hook is provided on the connecting plate.
[0009] Preferably, the two sides of the connecting plate are bent to form limiting baffles, and a limiting groove extending in the height direction is formed between the two limiting baffles. An extension plate extending in the height direction is provided on the side baffle, and the extension plate extends into the limiting groove. The first locking hole is provided on the extension plate.
[0010] Preferably, the base has second locking holes spaced apart along the left and right directions on the corresponding side baffle, and the bottom end of the side baffle has a second locking hook that engages with the second locking holes.
[0011] Preferably, the top pressure plate includes an overlapping first pressure plate and a second pressure plate, which are connected by a laterally adjustable connecting structure, and the connecting plate is integrally bent at the ends of the first and second pressure plates that are far apart from each other.
[0012] Preferably, the laterally adjustable connection structure includes a first positioning hole spaced apart on the first pressure plate in the left-right direction, a second positioning hole spaced apart on the second pressure plate 34 in the left-right direction, and a locking member passing through the first positioning hole and the second positioning hole and locking the two together.
[0013] Preferably, both the first pressure plate and the second pressure plate have U-shaped cross-sections, are nested inside each other, and can slide relative to each other in the left-right direction.
[0014] Preferably, the front and rear limiting structure includes a front baffle and / or a rear baffle fixed to the base, and at least one detachable baffle; at least two sets of third locking holes are spaced apart along the front-rear direction on the base, each set of third locking holes including at least one locking hole; the detachable baffle has at least one locking plate that engages with the third locking hole, and a support plate whose bottom end forms an abutment support with the upper surface of the base, the support plate being set at an angle to the detachable baffle.
[0015] Secondly, the present invention provides a power distribution device, including an electrical module and a compatibility fixing device as described in any of the above claims, wherein the electrical module is fixed by the compatibility fixing device.
[0016] The positive effects of this invention are as follows: The invention utilizes two side baffles arranged opposite each other with adjustable spacing to accommodate components of different widths (such as electrical modules in power distribution equipment); the top pressure plate, with adjustable length and height, not only matches the position of the side baffles but also accommodates components of different heights; combined with the front and rear limiting structures on the base, reliable positioning of the component in the width, length, and height directions is achieved, ensuring the component is firmly fixed within the accommodating space; the entire device can accommodate components of various sizes without the need for customized special accessories, making it more flexible to use, while also shortening the production and assembly cycle and facilitating spare parts management.

[0026] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples and should not be used to limit the scope of protection of the present invention.
[0027] It should be noted that, unless otherwise stated, the technical or scientific terms used in this invention should have the ordinary meaning as understood by one of ordinary skill in the art.
[0028] Firstly, the compatibility fixing device structure of the embodiments of the present invention is as follows: Figures 1 to 7 As shown, it includes a base 1, side baffles 2, a top pressure plate 3, and a front and rear limiting structure. The two side baffles 2 are mounted on the base 1, facing each other, forming a receiving space 20 for accommodating the fixed component. The distance between the two side baffles 2 is adjustable to accommodate fixed components of different widths. The top pressure plate 3 is positioned along the left-right direction, with an adjustable overall length. Its left and right ends are connected to the corresponding side baffles 2, and the side baffles 2 and the top pressure plate 3 are connected by a height-adjustable connection structure, allowing the height of the top pressure plate 3 to be adjusted to accommodate fixed components of different heights. The front and rear limiting structure is located on the base 1 to limit the fixed component in the front-back direction, preventing movement of the fixed component. Through the above structure in this embodiment, flexible adaptation and reliable fixing of fixed components of different sizes are achieved. It can accommodate multiple fixed component sizes without the need for customized accessories, reducing production costs and the number of spare parts required. Preferably, the base 1, side baffle 2, top pressure plate 3, and detachable baffle 14 involved in this invention are all made of sheet metal parts by bending, which facilitates mass production, reduces costs, and increases strength.
[0029] Optionally, the height-adjustable connection structure includes at least two first locking holes 21 spaced apart along the height direction on the side baffle 2, and a first hook 31 disposed on the top pressure plate 3. The first hook 31 is hooked into the first locking hole 21. The first hook 31 is bent into a hook shape and can be hooked and engaged with the first locking hole 21 on the side baffle 2. By engaging the first hook 31 with the first locking hole 21 at different height positions, the height position of the top pressure plate 3 can be adjusted, thereby pressing the fixed parts of different height dimensions with the top pressure plate 3. The structure is simple, feasible, and easy to manufacture.
[0030] Further, see Figures 5 to 7 As shown, the top pressure plate 3 has connecting plates 32 extending downward at both ends and adapted to be in contact with the side of the side baffle 2. The first hook 31 is provided on the connecting plate 32. Preferably, the connecting plate 32 is formed by bending the end of the top pressure plate 3 downward at 90°, and its side is in contact with the side of the side baffle 2. The first hook 31 is a hook-shaped hook that bends outward from the side of the connecting plate 32, with the hook facing the first locking hole 21 opened on the side baffle 2, so as to be locked into the first locking hole 21 at the corresponding height position, thereby achieving reliable locking of the height position.
[0031] Continue reading Figures 5 to 7 In some embodiments, the two sides of the connecting plate 32 are bent to form limiting baffles 321, and a limiting groove 322 extending in the height direction is formed between the two limiting baffles 321. The side baffle 2 is preferably configured as an inverted T-shaped structure, and its upper end is provided with an extension plate 22 extending in the height direction. The extension plate 22 extends into the limiting groove 322 and can slide in the height direction. This structure provides effective guidance and limiting during height adjustment, prevents the top pressure plate 3 from swaying, and ensures smooth and stable lifting. The first card hole 21 is provided on the extension plate 22.
[0032] For example, the base 1 has second locking holes 11 spaced apart along the left and right directions on the corresponding side baffles 2. The bottom end of the side baffles 2 is integrally provided with a bent second hook 23. The second hook 23 is inserted into the second locking holes 11 at different positions to change the distance between the two side baffles 2. When it is necessary to adjust the left and right distance, the side baffles 2 are lifted to make the second hook 23 exit the current second locking hole 11. After moving to the target position, the second hook 23 is inserted into the corresponding second locking hole 11.
[0033] like Figure 5 and Figure 6As shown, the top pressure plate 3 includes a first pressure plate 33 and a second pressure plate 34 that are stacked. The first pressure plate 33 and the second pressure plate 34 are connected by a laterally adjustable connecting structure. The connecting plate 32 is integrally bent at the ends of the first pressure plate 33 and the second pressure plate 34 that are far apart. In actual operation, the relative overlap length of the first pressure plate 33 and the second pressure plate 34 can be changed by the laterally adjustable connecting structure, thereby changing the total length of the entire top pressure plate 3 in the left and right directions to adapt to the installation requirements of fastened parts of different widths.
[0034] Furthermore, such as Figure 6 As shown, the laterally adjustable connection structure includes a first positioning hole 331 spaced apart on the first pressure plate 33 in the left-right direction, a second positioning hole 341 spaced apart on the second pressure plate 34 in the left-right direction, and a locking member passing through the first positioning hole 331 and the second positioning hole 341 and locking the two together; the first pressure plate 33 and the second pressure plate 34 are arranged vertically overlapping, so that the first positioning hole 331 and the second positioning hole 341 are aligned vertically, and the locking member is locked after passing through the aligned first positioning hole 331 and second positioning hole 341. The locking member can be a bolt and nut assembly, a fastener, etc.
[0035] Preferably, both the first pressure plate 33 and the second pressure plate 34 have U-shaped cross-sections, are nested inside each other, and can slide relative to each other in the left-right direction. Specifically, both the first pressure plate 33 and the second pressure plate 34 are formed from metal plates into U-shaped groove structures, with the U-shaped opening of one top plate slightly larger than the outer dimensions of the other top plate, allowing them to be fitted together to form a stacked structure, for example, the second pressure plate 34 is fitted over the first pressure plate 33, or vice versa. After nesting, the U-shaped bottom walls of the first pressure plate 33 and the second pressure plate 34 fit together, and the side walls on both sides constrain each other, which can limit the relative displacement of the first pressure plate 33 and the second pressure plate 34 in the front-back direction, increasing the stability of the connection; the U-shaped cross-section provides excellent bending and torsional stiffness, making the top pressure plate 34 have high overall strength and not easily deformed; moreover, the inner and outer nesting method has a guiding and limiting function.
[0036] In some embodiments, the front and rear limiting structure includes a front baffle 12 and / or a rear baffle 13 fixed to the base 1, and a detachable baffle 14. At least two sets of third locking holes 15 are spaced apart along the front-rear direction on the base 1, each set of third locking holes 15 including at least one locking hole (e.g., one, two, or more). The detachable baffle 14 has at least one locking plate 141 that engages with the third locking hole 15, and a support plate 142 whose bottom forms an abutment support with the upper surface of the base 1. The support plate 142 is angled (preferably 90°) to the detachable baffle 14.
[0037] Specifically, the front baffle 12 and the rear baffle 13 can be configured as needed: only the front baffle 12 can be configured, only the rear baffle 13 can be configured, or both can be configured. Preferably, the front baffle 12 and the rear baffle 13 are integrally formed by bending the front and rear edges of the base. Multiple sets of third locking holes 15 are distributed on the base 1 along the front-rear direction. Each set may include one or more locking holes. Correspondingly, the bottom of the detachable baffle 14 is provided with one or more locking plates 141 to simultaneously engage with multiple locking holes in the same set, thereby enhancing the stability of the connection. When the front baffle 12 and the rear baffle 13 are configured simultaneously, these third locking holes 15 are located in the area between the front baffle 12 and the rear baffle 13. In one usage scenario, the base 1 is equipped with both a front baffle 12 and a rear baffle 13, but no removable baffle 14 is installed. Larger components are directly clamped and limited by the front baffle 12 and rear baffle 13. When the components are smaller in the front-to-back direction, a removable baffle 14 is installed at a suitable location in a set of third locking holes 15. This removable baffle 14 cooperates with the front baffle 12 or the rear baffle 13 to clamp and limit the components. Furthermore, regardless of whether the base 1 has a front baffle 12 and / or a rear baffle 13, two removable baffles 14 can be installed for front-to-back limiting: one removable baffle 14 is installed at each of the third locking holes 15 at the corresponding positions at the front and rear ends of the component, allowing the two removable baffles 14 to directly clamp and limit the components. When only the front baffle 12 or only the rear baffle 13 is present, the fixed component can be clamped by the front baffle 12 or the rear baffle 13 in conjunction with a detachable baffle 14, or two detachable baffles 14 can be used directly for limiting. This achieves flexible limiting of fixed components of different sizes in the front-rear direction. Moreover, the front baffle 12 and the rear baffle 13 also reinforce the base 1.
[0038] Secondly, embodiments of the present invention also provide a power distribution device, including any of the compatible fixing devices and electrical modules described in the above embodiments. The compatible fixing device is used to fix the electrical module (such as a battery) inside the power distribution device, and the base 1 is fixedly connected to the cabinet of the power distribution device. The power distribution device can be a communication power supply cabinet, a UPS uninterruptible power supply, a power operating power supply, a DC power supply, an integrated energy storage unit, or other electrical equipment.
[0039] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the scope of protection of this invention.
