Description

Technical Field

[0001] The utility model relates to the technical field of five accessories, in particular to a chassis base. Background Art

[0002] Currently, many mechanical products have chassis, which are used to protect the electronic components inside and prevent dust from adhering. However, the chassis with electronic components increases its weight. In order to prevent the chassis from being placed directly on the ground, a base needs to be added to the bottom of the chassis. Conventional chassis bases are generally matched with the chassis, but the sizes of chassis vary. Traditional chassis bases cannot be adjusted in size, which makes it difficult for the chassis and base to adapt to each other. Utility Model Content

[0005] (2) Technical solution

[0006] In order to achieve the purpose of adjusting the above-mentioned chassis base, the utility model provides the following technical solutions: a chassis base, comprising four square bottom plates, a center block is provided in the center of the four square bottom plates, and extension strips are fixedly installed at the four outer corners of the center block, and the surface of the extension strip is provided with a strip hole, and a slider is slidably installed inside the strip hole, and mounting grooves are provided on both sides of the slider, and a limiting ring is embedded in the opening of the mounting groove, and a locking ball is provided inside the limiting ring, and a limiting plate is fixedly installed on the side of the locking ball, and a spring is provided on the side of the limiting plate, and a locking groove is provided on the inner wall of the extension strip and on both sides of the strip hole.

[0007] Preferably, a central pad is fixedly installed on the bottom of the central block.

[0008] Preferably, bottom plate pads arranged in a ring shape are fixedly mounted on the bottom of the square bottom plate.

[0009] Preferably, through holes corresponding to the extension bars are provided inside the square bottom plates, and the square bottom plates are slidably connected to the center block via the extension bars and the through holes.

[0010] Preferably, the square bottom plate is slidably connected to the extension bar via a slider.

[0011] Preferably, the slider is engaged with the extension bar via a spring, a locking ball and a locking groove.

[0012] Preferably, a notch corresponding to the center block is provided on one side of the inner corner of the square bottom plate.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a chassis base with the following beneficial effects:

[0015] The chassis base applies force to the four square bottom plates in advance according to the chassis size, and the square bottom plates slide away along the extension direction of the extension strip, while the center block is always in the center position of the four square bottom plates; while the square bottom plates slide away, the sliders also slide in the bar holes. When the square bottom plates stop sliding, the spring pushes the card balls into the corresponding card slots to lock the position of the sliders, thereby unlocking the four square bottom plates after the adjusted size. In this process, the size of the chassis base is adjusted to adapt to the size of the chassis. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] See also Figure 1-4 A computer chassis base includes four square bottom plates 1, each with a center block 2 at its center. Notches corresponding to the center blocks 2 are defined at the inner corners of the square bottom plates 1. Center pads 3 are fixedly mounted to the bottoms of the center blocks 2, while an annular array of bottom plate pads 4 is fixedly mounted to the bottoms of the square bottom plates 1. Rubber pads can be used to reduce vibration between the center pads 3 and the bottom plate pads 4. Universal wheels can also be installed on the bottoms of the center pads 3 and the bottom plate pads 4 to facilitate movement of the chassis.

[0026] See also Figure 5-7 , extension bars 5 are fixedly installed at the four outer corners of the center block 2, and through holes corresponding to the extension bars 5 are opened inside the square base plate 1. The square base plate 1 is slidably connected to the center block 2 through the extension bars 5 and the through holes to ensure that the square base plate 1 will not shift during the sliding and expansion process; a strip hole 6 is opened on the surface of the extension bar 5, and a slider 7 is slidably installed inside the strip hole 6. The square base plate 1 is slidably connected to the extension bar 5 through the slider 7 to ensure that the square base plate 1 will not shift during sliding.

[0027] See also Figure 5-7 , mounting grooves 8 are provided on both sides of the slider 7, and a limiting ring 9 is embedded in the opening of the mounting groove 8. A card ball 10 is provided inside the limiting ring 9, and a limiting plate 11 is fixedly installed on the side of the card ball 10. A spring 12 is provided on the side of the limiting plate 11. The inner wall of the extension strip 5 and both sides of the strip hole 6 are provided with card grooves 13, which are adapted to the card ball 10. The number of card grooves 13 is arranged at equal intervals. The slider 7 is mutually clamped with the extension strip 5 through the spring 12, the card ball 10 and the card groove 13.

[0028] Working principle: When in use, according to the size of the chassis, the four square bottom plates 1 are pre-pulled outwards, and the square bottom plates 1 slide open along the extension direction of the extension strips 5, while the center block 2 is always in the center of the four square bottom plates 1;

[0029] As the square bottom plate 1 slides away, the slider 7 will also slide in the strip hole 6. When the square bottom plate 1 stops sliding, the spring 12 pushes the card ball 10 into the corresponding card slot 13, and the position of the slider 7 can be locked, and then the four square bottom plates 1 after the adjusted size are unlocked. In this process, the size of the chassis base is adjusted, and then the size of the chassis is adapted.

[0030] On the contrary, if the four square bottom plates 1 are pushed inward, the four square bottom plates 1 will move closer to the center block 2, and then the area occupied by the four square bottom plates 1 will be reduced, and then the size of the chassis will be suitable.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
