Description

Technical Field

[0001] This utility model specifically relates to the field of drawer-type switch cabinet technology, and more specifically to a low-voltage switch cabinet with adjustable drawer units. Background Technology

[0002] Low-voltage switchgear is an electrical device used for the distribution, control, and protection of electrical energy in low-voltage power distribution systems. Among them, drawer-type low-voltage switchgear is a common and widely used type. Each drawer in a low-voltage switchgear is an independent functional unit that can install various electrical components such as circuit breakers, contactors, relays, and fuses. The drawers are connected to the cabinet via guide rails, allowing for easy insertion and removal of components. This facilitates the installation, maintenance, and replacement of electrical components, greatly improving maintenance efficiency.

[0003] However, in practice, it has been noted that the location of the drawer inside the switch cabinet needs to be considered in advance. When the function of the drawer is changed, the electrical components inside the drawer need to be changed. However, the space inside the drawer is limited and cannot accommodate extra components. Therefore, it is necessary to remake a matching drawer, and the old drawer can only be left idle. This results in high costs when replacing the drawer. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model embodiment provides a low-voltage switch cabinet with adjustable drawer unit, including a metal frame 4, with mounting columns 5 fixedly connected to both sides of the metal frame 4, and a drawer bracket 6 arranged in a rectangular array fixedly connected between two of the mounting columns 5, and a handcart-type drawer unit 3 is placed on top of each of the drawer brackets 6.

[0028] The drawer bracket 6 includes a hollow support plate 61. The hollow support plate 61 has grooved slide rails 62 that are movably connected to the handcart-type drawer unit 3 on both sides. The bottom of the hollow support plate 61 is equipped with a rectangular array of fixed adjusters 63, and the sides of the fixed adjusters 63 are fixedly connected to the metal frame 4 and the mounting post 5 respectively.

[0029] Furthermore, the fixed adjuster 63 includes a rectangular connecting seat 631 fixedly connected to the bottom of the hollow support plate 61, and the inner side of the rectangular connecting seat 631 is provided with a threaded hole, and the hollow support plate 61 is provided with a through hole corresponding to the threaded hole.

[0030] Furthermore, the rectangular connecting seat 631 is threaded with a threaded adjusting rod 632, and one end of the threaded adjusting rod 632 is provided with a rectangular groove 633, while the other end of the threaded adjusting rod 632 is movably connected to an L-shaped support plate 634.

[0031] By adopting the above technical solution, the position of the hollow support plate 61 inside the metal frame 4 can be changed through the cooperation of the holes on the mounting column 5 and the fixing adjuster 63, so as to make enough space for the drawer below. Furthermore, the threaded adjustment rod 632 can be rotated with a special tool, and the height of the hollow support plate 61 can be adjusted within a small range through the threaded cooperation between the threaded adjustment rod 632 and the rectangular connecting seat 631, ensuring versatility.

[0032] More specifically, the end of the threaded adjusting rod 632 is rotatably connected to the L-shaped support plate 634 via a bearing, and the side of the L-shaped support plate 634 is fixedly connected to the metal frame 4 and the mounting column 5 respectively. The end of the threaded adjusting rod 632 with a rectangular groove 633 passes through the through hole on the hollow support plate 61.

[0033] Furthermore, the handcart-type drawer unit 3 includes a drawer frame 31, both sides of which are inserted into corresponding groove slide rails 62, and electrical devices 32 and busbar connectors 34 are respectively installed at both ends of the drawer frame 31.

[0034] Furthermore, a combined cover plate 33 is provided above the end of the drawer frame 31 near the electrical device 32, and a cylindrical insert rod 35 is integrally provided at the bottom of the combined cover plate 33. A cylindrical slot corresponding to the cylindrical insert rod 35 is opened above the drawer frame 31 and the combined cover plate 33, and the cylindrical insert rod 35 is inserted into the cylindrical slot.

[0035] By adopting the above technical solution, through the columnar insert 35 set at the bottom of the combined baffle 33 and the columnar slot corresponding to the columnar insert 35 at the top of the combined baffle 33, different numbers of combined baffles 33 can be combined according to the size of the gap to cover the gap, thereby ensuring the sealing between the two handcart-type drawer units 3 and improving safety.

[0036] Furthermore, the combined shield 33 is C-shaped, and the inner side of the combined shield 33 is fixedly connected with reinforcing plates in a rectangular array.

[0037] Furthermore, the mounting column 5 has bolt mounting holes arranged in a rectangular array, while the L-shaped support plate 634 has symmetrical countersunk holes. The bolts are placed in the countersunk holes, and the ends of the bolts are threaded through the countersunk holes and bolt mounting holes to be connected to nuts.

[0038] Furthermore, a sealing box plate 1 is fixedly connected to the outside of the metal frame 4, and the side of the handcart-type drawer unit 3 is provided with an end cover plate 2 fixedly connected to the metal frame 4 to cover the outside of the metal frame 4 and protect the internal electrical components.

[0039] The working principle of this utility model is as follows: In use, firstly, the L-shaped support plate 634 is fixed to the appropriate position on the mounting column 5 and the metal frame 4 using bolts. Then, the hollow support plate 61 is placed above the threaded adjusting rod 632. Rotating the threaded adjusting rod 632 causes the hollow support plate 61 to slowly descend through the threaded transmission between the threaded adjusting rod 632 and the rectangular connecting seat 631 at the bottom of the hollow support plate 61. The position of the hollow support plate 61 inside the metal frame 4 can also be adjusted within a small range. Then, the electrical components are installed into the handcart-type drawer unit 3, and the end of the handcart-type drawer unit 3 is placed above the hollow support plate 61. By sliding along the grooved rails 62 on both sides of the perforated support plate 61, the handcart-type drawer unit 3 is placed above the perforated support plate 61. At this time, due to the change in the distance between the two perforated support plates 61, there is also a gap between the two handcart-type drawer units 3. Depending on the size of the gap, several combined cover plates 33 are taken, and the cylindrical inserts 35 at the bottom of the combined cover plates 33 are inserted into the cylindrical slots at the corresponding positions on the upper part of the corresponding drawer outer frame 31. The gap is covered by the combined cover plates 33, and it can be used without replacing the handcart-type drawer unit 3. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
