Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifting components, and in particular relates to a vehicle bracket with adjustable height. Background Art
[0002] In the prior art, traditional vehicle (security) brackets, such as Figure 1 As shown, the top column component 1 adjusts the height of the bracket by moving the top column 12 thereon up and down relative to the base component 2. The bracket has a single lifting structure, and only the top column 12 can adjust the height, so the overall usable height is relatively limited.
[0003] Even if there are currently existing structures that can add additional height, e.g. Figure 2 As shown, an adjustment screw 13 extends from the top head 11 of the top column component 1. This adjustment screw 13 can be screwed in and out of the top column 12, allowing the top column component 1 to have greater extension space than traditional structures, thereby achieving height adjustment of the vehicle stand. However, this structure also only increases the height of the top column component 1, while the size of the base component 2 remains unchanged. As the height of the top column component 1 increases, its stability decreases.
[0004] In view of the above-mentioned prior art, it is necessary to reasonably improve the existing vehicle support structure. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Utility Model Content
[0005] The task of this utility model is to provide a vehicle stand with adjustable height. On the basis of existing products, it expands the scope of use of the vehicle stand by adding an adjustable height function of the base, so that it can adapt to more usage scenarios, reduce the user's working frequency, and the increase in the height of the stand does not affect its stability.
[0006] The task of the utility model is accomplished in this way. A vehicle bracket with adjustable height includes a top column component and a base component. The top column component is used to support the vehicle. The base component includes a base sleeve and a base leg. The top column component is inserted into the base sleeve. The characteristic is that: the base leg is a hollow structure and is provided with at least one base leg adjustment hole. When the bracket height needs to be raised, the extension leg is inserted from the lower end of the base leg. The extension leg is provided with at least one extension leg adjustment hole. When at least one of the base leg adjustment holes and at least one of the extension leg adjustment holes are connected to each other, a pin is inserted to fix the relative position between the base leg and the extension leg.
[0007] In a specific embodiment of the present invention, the lower end of the base leg is provided with a base foot supported on the ground, and the lower end of the extension leg is provided with an extension foot supported on the ground.
[0008] In another specific embodiment of the present invention, an extension leg is inserted into the lower end of the base leg.
[0009] In another specific embodiment of the present invention, multiple extension legs are inserted into the lower end of the base leg, and the extension legs are hollow structures. The next extension leg is inserted into the lower end of the previous extension leg, and when there is at least one pair of extension leg adjustment holes on the two extension legs that pass through, a pin is inserted to fix the relative positions of the two extension legs.
[0010] In another specific embodiment of the present invention, three or more base legs are provided and are evenly welded to the circumferential direction of the base sleeve.
[0011] In another specific embodiment of the present invention, blocking members are provided at both ends of the pin shaft to prevent the pin shaft from slipping out of the interpenetrating base leg adjustment hole and the extension leg adjustment hole.
[0012] In a further specific embodiment of the present invention, the blocking member is a retaining ring or a B-type elastic bayonet.
[0013] Due to the adoption of the above-mentioned structure, the present invention has the following beneficial effects: first, an extension leg that is telescopic relative to the base leg is installed at the lower end of the base leg, and the relative position of the two is fixed by adjusting holes opened on the two legs, thereby realizing the adjustment of the bracket height. This structure can achieve a wider range of height adjustment, conform to more usage scenarios, reduce the user's working frequency, and its stability is more stable as the bracket height increases; second, the extension leg in the bracket structure can be removed, and can still be used as a normal bracket after removal; third, the bracket structure is not limited to using only a single-section extension leg, and multiple-section extension legs can be used to achieve a wider range of usage heights.

DETAILED DESCRIPTION
[0021] The specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the applicant's description of the embodiments does not limit the technical solution. Any changes in form rather than substance based on the concept of the present invention should be regarded as within the scope of protection of the present invention.
[0022] In the following description, all concepts related to directionality or orientation such as up, down, left, right, front and back are based on the positions shown in the corresponding drawings. They are only used to facilitate the description of the technical solution provided by the present invention and to simplify the description in conjunction with the drawings. Therefore, they should not be understood as a special limitation on the technical solution provided by the present invention.
[0023] See also Figure 4 、 Figure 5 The utility model relates to a vehicle stand with adjustable height, comprising a top column component 1 and a base component 2. The top column component 1 is used to support a vehicle, specifically comprising a top head 11 that cooperates with the vehicle and a top column 12 that supports the top head 11.
[0024] The base component 2 includes a base sleeve 21 and three supporting base legs 22. The three base legs 22 are welded to the base sleeve 21. The top column component 1 is inserted into the base sleeve 21, and the height of the top column component 1 relative to the base sleeve 21 is adjustable. The lower ends of the base legs 22 are provided with base feet 221 that support the ground. The base legs 22 are hollow and have at least one base leg adjustment hole 222. When the height of the bracket needs to be raised, an extension leg 24 is inserted from the lower end of the base leg 22. The lower end of the extension leg 24 is provided with an extension foot 241 that supports the ground and has at least one extension leg adjustment hole 242.
[0025] When at least one extension leg adjustment hole 242 on the extension leg 24 intersects at least one base leg adjustment hole 222, a pin 23 is inserted therein, thereby fixing the relative position between the base leg 22 and the extension leg 24. Stoppers 231 are provided at both ends of the pin 23 to prevent the pin 23 from slipping out of the intersecting base leg adjustment hole 222 and extension leg adjustment hole 242. The type of stopper 231 is not limited; in this embodiment, it is preferably a retaining ring or a B-type elastic bayonet.
[0026] In the structure described in the present invention, when the extension legs 24 are not installed, the top column component 1 and base component 2 function normally. The base component 2 is supported on the ground by the base legs 22, and at this point, the base component 2 is at its lowest height. When the extension legs 24 are installed, the pins 23 are inserted from the lowest base leg adjustment hole 222 to the highest base leg adjustment hole 222, gradually increasing the height of the base component 2.
[0027] Of course, the extension leg 24 is not limited to installing one section. The extension leg 24 is also a hollow structure. The next section of the extension leg 24 is inserted into the lower end of the previous section of the extension leg 24. When there is at least one pair of extension leg adjustment holes 242 on the two sections of the extension leg 24 that pass through, the pin shaft 23 is inserted to fix the relative positions of the two sections of the extension leg 24. Similarly, multiple sections of the extension leg 24 can be installed to achieve a wider range of usage height.
[0028] Of course, the number of extension legs 24 is not limited to three, and may be four, five or even more, based on the performance and strength.
