Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and more specifically, to an adjustable-size electrical cabinet base. Background Technology

[0002] When electrical cabinets are manufactured in the factory, they sometimes need to be moved. If they are pushed directly on the ground, the electrical cabinet will rub against the ground, which is not only time-consuming and laborious, but also affects the quality of the electrical cabinet. Therefore, a base for moving electrical cabinets is needed.

[0003] In the existing technology, the base used for moving electrical cabinets is generally a holding platform with several wheels installed at the bottom. The rotation of the wheels can reduce the friction during movement. However, there are some problems in its use. Because electrical cabinets are tall, the base is made larger to maintain the stability of the electrical cabinet during movement. However, when passing through narrow places, the larger base cannot pass through. Therefore, an adjustable base is needed. However, the adjustment of the base is also inconvenient due to the friction. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing bases are inconvenient to adjust in size, and to design an adjustable electrical cabinet base.

[0005] To achieve the above objectives, the technical solution of this utility model is an adjustable-size electrical cabinet base, including a holding plate. Multiple supporting channel steels are installed on the lower surface of the holding plate. A push handle is installed on one side of the upper end of the holding plate. Support wheels are provided on both sides of the lower part of the holding plate. The support wheels are installed on the supporting channel steel in the middle of the holding plate. Guide cylinders are installed at the front and rear ends of the lower surface of the holding plate. Telescopic rods are provided on both sides inside the guide cylinders. Universal casters that can move up and down are installed at the lower end of the telescopic rods.

[0006] Furthermore, an adjusting screw is installed on the upper end of the universal wheel, and a threaded hole is opened at one end of the telescopic rod. The upper end of the adjusting screw and the threaded hole are connected by threads. The upper end of the adjusting screw extends through the threaded hole to the top of the telescopic rod, and a handle is installed on the upper end of the adjusting screw.

[0007] Furthermore, the guide cylinder has limit holes at both ends, the telescopic rod has multiple positioning holes, and the limit holes are equipped with limit pins installed on the guide cylinder.

[0008] Furthermore, support telescopic shafts are installed at the four corners of the lower surface of the holding plate.

[0009] The beneficial effects of this utility model are as follows: By placing the electrical cabinet on the display board and then rotating the support wheels and casters, the friction force when moving the electrical cabinet can be reduced. By moving the casters up and down, the casters can be kept out of contact with the ground, thereby reducing friction when moving the telescopic rod. This also facilitates the adjustment of the base size, allowing it to pass through narrow spaces. After passing through, the telescopic rod can be pulled outward to increase the size of the base and enhance stability. Furthermore, when the base is moved to an inclined plane, the height of the casters can be adjusted to maintain the stability of the base. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] This utility model provides, for example Figure 1-5 The adjustable size electrical cabinet base shown includes a holding plate 1, multiple support channel steels 2 installed on the lower surface of the holding plate 1, a push handle 3 installed on one side of the upper end of the holding plate 1, support wheels 4 provided on both sides of the lower part of the holding plate 1, the support wheels 4 are installed on the support channel steel 2 in the middle position of the holding plate 1, guide cylinders 5 are installed at the front and rear ends of the lower surface of the holding plate 1, telescopic rods 6 are provided on both sides inside the guide cylinders 5, and universal wheels 7 that can move up and down are installed at the lower end of the telescopic rods 6.

[0019] The adjustment process for this base is as follows: Under normal conditions, the lower ends of the casters 7 and 4 are on the same plane, facilitating the movement of the electrical cabinet. When adjusting the position of the telescopic rod 6, the casters 7 are moved upwards beforehand, so that the lower ends of the 4 are placed on the ground. Only one side of the casters 7 on both sides of the 4 can rest on the ground. After the electrical cabinet is placed on the shelf 1, the base can be moved by pushing the handle 3. The rotation of the 4 and 7 reduces the friction during base movement. Generally, extending the telescopic rod 6 outwards increases the size of the base and improves stability. When moving the base, the 4 and one side of the caster 7 rest on the ground, and the shelf 1 is slightly... The tilt is slight enough not to cause the electrical cabinet to wobble. During movement, if the telescopic rod 6 needs to be shortened, the worker can simply push the upper end of the telescopic rod 6 (which is not in contact with the ground) of the caster 7 inwards, and then press the tray 1 to one side, causing the caster 7 in contact with the ground to lift up. The caster 7, which was originally above the ground, will then fall to the ground, making it easier to shorten the other set of telescopic rods 6, thereby reducing the size of the base. When the telescopic rod 6 needs to be extended, the caster 7 is lifted up in the same way, and the corresponding telescopic rod 6 is moved. When encountering an incline, the height of the caster 7 can be adjusted so that the caster 7 and the lower end of the support wheel 4 form an incline, which helps to stabilize the electrical cabinet during movement.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The universal wheel 7 is equipped with an adjusting screw 8 at its upper end. One end of the telescopic rod 6 has a threaded hole 9. The upper end of the adjusting screw 8 and the threaded hole 9 are connected by a thread. The upper end of the adjusting screw 8 passes through the threaded hole 9 and extends above the telescopic rod 6. A handle 10 is installed on the upper end of the adjusting screw 8. The adjusting screw 8 can be rotated by the handle 10. The adjusting screw 8 and the universal wheel 7 can move up and down by the threaded connection between the adjusting screw 8 and the threaded hole 9.

[0021] Refer to the instruction manual appendix Figure 1 The guide cylinder 5 has limit holes 11 at both ends, and the telescopic rod 6 has multiple positioning holes 12. The limit holes 11 are equipped with limit pins 13 installed on the guide cylinder 5. Pulling the lower end of the limit pin 13 out of the positioning hole 12 makes it easier for the telescopic rod 6 to move. Then, inserting the lower end of the limit pin 13 into the positioning hole 12 can position the telescopic rod 6 and prevent it from moving.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 4 Included with instruction manual Figure 5 Support telescopic shafts 14 are installed at the four corners of the lower surface of the holding plate 1. Under normal conditions, the support telescopic shafts 14 are in a shortened state, and the casters 7 will land on the ground before the support telescopic shafts 14. When it is necessary to adjust the height of the casters 7, the support telescopic shafts 14 are extended, so that the lower end of the support telescopic shafts 14 can be supported on the ground, so that the holding plate 1 is kept in an inclined state and the base is prevented from shaking.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
