Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and in particular to a sliding device for switch cabinets. Background Technology

[0002] The sliding mechanism of the switch cabinet is an important component of the switch cabinet, mainly used to open and close the cabinet door, lock it, and connect and disconnect the internal circuits.

[0003] Existing sliding mechanisms for switchgear typically only have locking mechanisms at both ends. These mechanisms secure components as they move into or out of the switchgear, failing to provide adequate support when components are moved to other positions, resulting in poor performance. Furthermore, existing sliding mechanisms lack heat dissipation mechanisms, meaning heat generated during operation can only be dissipated through ventilation slots on the switchgear casing, leading to ineffective cooling. Therefore, we propose a new sliding device for switchgear. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a sliding device for a switch cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sliding device for a switch cabinet is designed, including two parallel slide rails, each slide rail having a slider slidably connected to its top, a shelf between the two sliders, a mounting base for fixing components stacked on top of the shelf, and several connecting blocks installed on the edges of the shelf, wherein the bottoms of two connecting blocks are stacked on the corresponding sliders and fastened to the sliders.

[0006] Each slider has a strip connecting plate installed on one side of its bottom. Each strip connecting plate has a strip groove on its side. A lead screw is installed between the two slide rails. Both ends of the lead screw are fixed to the side of the slide rail, and both ends of the lead screw pass through the corresponding strip groove.

[0007] Both ends of the lead screw are fitted with adjusting screw sleeves, which are threadedly connected to the lead screw, and one end of each adjusting screw sleeve rests against the side of the strip connecting plate;

[0008] At least one mounting hole is provided on the top of the shelf, and a mounting ring is coaxially connected to the bottom of the shelf. The top of the mounting ring is connected to the mounting hole. A fan is installed inside the mounting ring, and the top of the fan extends into the mounting hole.

[0009] A wiring groove is provided on one side of the top of the shelf. The wires connected to the fan are placed in the wiring groove and connected to the snap-action temperature control switch. The snap-action temperature control switch is fixed in the wiring groove. A conductive plate is also installed on the top of the shelf. The conductive plate is electrically connected to the snap-action temperature control switch. When the mounting base for fixing the components is placed on the shelf, the conductive plate is electrically connected to the mounting base.

[0010] Preferably, each slide rail is equipped with a strip mounting plate on one side of its bottom, and each strip mounting plate is fixed to the inner wall of the switch cabinet.

[0011] Preferably, the lead screw is located at the end of the slide rail near the opening of the switch cabinet.

[0012] Preferably, a limiting block is vertically installed on the top of each connecting block, and the spacing between the limiting blocks is adapted to the mounting base of the fixed component.

[0013] Preferably, the diameter of the adjusting screw sleeve at the end near the strip connecting plate is greater than the width of the strip groove.

[0014] Preferably, there is a gap between the top of the fan and the top of the shelf.

[0015] Preferably, the top of the wiring channel is provided with a cover plate that covers the opening of the wiring channel.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A sliding device for a switchgear includes two parallel slide rails 10. Each slide rail 10 has a strip mounting plate 9 installed on one side of its bottom. Each strip mounting plate 9 is fixed to the inner wall of the switchgear. Figure 4 As shown, the slide rail 10 can be fixed to the inner wall of the switch cabinet.

[0026] like Figure 1 and Figure 4 As shown, each slide rail 10 has a slider 17 slidably connected to its top. A shelf 11 is provided between two sliders 17. A mounting base for fixing components is stacked on top of the shelf 11. Several connecting blocks 6 are installed on the edges of the shelf 11. The bottoms of two connecting blocks 6 are stacked on the corresponding sliders 17 and fastened to the sliders 17. Through the cooperation between the sliders 17 and the slide rail 10, the sliders 17 can move along the slide rail 10, which in turn can drive the shelf 11 to move along the slide rail 10. Thus, components can be removed from the switch cabinet when needed.

[0027] like Figure 1 and Figure 2 As shown, each slider 17 has a strip connecting plate 8 installed on one side of its bottom. Each strip connecting plate 8 has a strip groove 12 on its side. A lead screw 14 is provided between the two slide rails 10. Both ends of the lead screw 14 are fixed to the side of the slide rail 10, and both ends of the lead screw 14 pass through the corresponding strip groove 12. In actual use, the cooperation between the lead screw 14 and the strip groove 12 can prevent the slider 17 from falling off the slide rail 10, thereby preventing the shelf 11 from falling off.

[0028] like Figure 2 and Figure 3As shown, both ends of the lead screw 14 are fitted with adjusting sleeves 16, which are threadedly connected to the lead screw 14. One end of each adjusting sleeve 16 rests against the side of the strip connecting plate 8. The diameter of the adjusting sleeve 16 near the strip connecting plate 8 is greater than the width of the strip groove 12. In actual use, after the shelf 11 is moved to the preset position, the operator can tighten the adjusting sleeve 16. The adjusting sleeve 16 fixes the strip connecting plate 8 on the slide rail 10, thus fixing the shelf 11.

[0029] like Figure 1 and Figure 3 As shown, at least one mounting hole 2 is provided on the top of the shelf 11, and a mounting ring 15 is coaxially connected to the bottom of the shelf 11. The top of the mounting ring 15 is connected to the mounting hole 2. A fan 4 is installed inside the mounting ring 15, and the top of the fan 4 extends into the mounting hole 2. The fan 4 can blow air from the switch cabinet to the components to dissipate heat from the components.

[0030] It should be noted that there is a gap between the top of the fan 4 and the top of the shelf 11, so that the mounting bracket will not collide with the fan 4 when it is placed.

[0031] like Figure 1 As shown, a wiring groove 5 is provided on one side of the top of the shelf 11. The wire 3 connected to the fan 4 is placed in the wiring groove 5 and is connected to the snap-action temperature control switch 18. The snap-action temperature control switch 18 is fixed in the wiring groove 5. A conductive plate 7 is also installed on the top of the shelf 11. The conductive plate 7 is electrically connected to the snap-action temperature control switch 18. When the mounting base for fixing the components is placed on the shelf 11, the conductive plate 7 is electrically connected to the mounting base. In this way, during use, the fan 4 can be powered by the switch cabinet through the conductive plate 7 and the wire 3, so that the fan 4 can work normally. When the component temperature is too high, the snap-action temperature control switch 18 closes, the fan 4 works, and blows air onto the surface of the component, accelerating the airflow speed inside the switch cabinet, thereby increasing the exchange speed of air inside the switch cabinet with the outside air through the heat dissipation slots on the switch cabinet, and improving the heat dissipation effect.

[0032] Specifically, when the shelf 11 needs to be moved, the operator first rotates the adjusting screw sleeve 16 to loosen it, and then pulls the shelf 11 to remove it from the switch cabinet. Simultaneously, the component mounting bases installed on the shelf 11 and the components on them are moved out of the switch cabinet along with the shelf 11. After the shelf 11 is moved to the preset position, the operator tightens the adjusting screw sleeve 16, with one end of the adjusting screw sleeve 16 firmly abutting against the strip connecting plate 8, thus moving the shelf 11... 1. Fix the shelf 11 in place and complete the adjustment of the shelf 11 position. When the shelf 11 is moved into the switch cabinet, the components on the shelf 11 will be connected to the power supply inside the switch cabinet. At the same time, the snap-action temperature control switch 18 will turn on the power. When the surface temperature of the components is too high, the snap-action temperature control switch 18 will close, and the fan 4 will start working to dissipate heat from the components. When the component temperature drops to the preset value, the snap-action temperature control switch 18 will open, and the fan 4 will stop working, so that the components are kept within the optimal temperature range.

[0033] Furthermore, the lead screw 14 is located at the end of the slide rail 10 near the opening of the switch cabinet, which makes it convenient for staff to rotate the adjusting screw sleeve 16, thereby facilitating the movement or fixing of the shelf 11.

[0034] Furthermore, such as Figure 3 As shown, each connecting block 6 has a limit block 1 vertically installed on its top. The spacing between the limit blocks 1 is adapted to the mounting base of the fixed component, which can limit the mounting base and prevent the mounting base from moving relative to the shelf 11.

[0035] Furthermore, such as Figure 2 As shown, the top of the wiring trough 5 is provided with a cover plate 13, which covers the opening of the wiring trough 5. In actual use, the cover plate 13 can block the opening of the wiring trough 5, so that the wire 3 is in a closed space and is protected.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
