A jack is commonly used as a lifting device for lifting and supporting a vehicle, thereby facilitating repair of the vehicle. At present, with the development of the automobile industry, the variety of automobiles is also increasing, and automobile manufacturers usually produce matched jack structures aiming at different automobile structures. That is, the jack can only be used on a specific vehicle type or a vehicle type with similar structure in the using process. When the jack is used in other vehicle types with larger structural differences, the vehicle body can slide in the lifting process due to structural mismatch, so that potential safety hazards exist. Therefore, the jack has poor universality and improves the use cost of customers.

Referring to fig. 1, in order to solve the problem of poor versatility of the existing jack, a jack 100 is provided. The jack 100 includes a top 10 and a base 20, and a telescopic portion 30 connecting the top 10 and the base 20, wherein the telescopic portion 30 can drive the top 10 to move along a preset telescopic direction toward a direction close to or far away from the base 20.

Thus, the first fixing groove 101 and the second fixing groove 102 have simple structures and are easy to process, and the first fixing groove 101 and the second fixing groove 102 can be better matched with the lifting structure on the vehicle body, so that the stability of the jack 100 is improved.

In one embodiment, as shown in fig. 1, the plug 10 includes a first side plate 11, a second side plate 12, and an end plate 13 connecting the first side plate 11 and the second side plate 12. The first side plate 11 and the second side plate 12 are arranged at intervals along a first preset direction and are provided with mounting grooves 105, and the plug 10 is sleeved and connected to one end of the telescopic part 30, which is far away from the base 20, through the mounting grooves 105. The notch of the first fixing groove 101 is disposed on the end plate 13, and the first fixing groove 101 sequentially penetrates the first side plate 11 and the second side plate 12 along a first preset direction. Thus, the plug 10 has a simple structure, and the processing difficulty of the plug 10 can be reduced. The fitting of the jack 10 and the extension 30 is also relatively simple, and the overall fitting efficiency of the jack 100 can be improved.

In one embodiment, the first side panel 11, the second side panel 12 and the end panel 13 are integrally formed. Thus, the processing difficulty of the plug 10 is reduced, and the structural strength of the plug 10 is improved.

Specifically, the first side plate 11, the second side plate 12, and the end plate 13 may be an integrally press-molded structure or an integrally cast-molded structure. However, the first side plate 11, the second side plate 12, and the end plate 13 may be formed by welding.

In an embodiment, two ends of the telescopic portion 30 along a preset telescopic direction are respectively hinged to the plug 10 and the base 20. In this way, the movement of the telescopic part 30 is smoother, so that the plug 10 is conveniently driven to move, and the function of lifting or lowering the vehicle can be realized.

Further, in one embodiment, the telescoping portion 30 includes a first upper arm 31, a second upper arm 32, a first lower arm 33, a second lower arm 34, a first connecting post 35, a second connecting post 36, and a screw 37. One end of the first upper support arm 31 is hinged to the first lower support arm 33 through a first connecting column 35, one end of the first upper support arm 31 away from the first lower support arm 33 is hinged to the plug 10, and one end of the first lower support arm 33 away from the first upper support arm 31 is hinged to the base 20. One end of the second upper arm 32 is hinged to the second lower arm 34 via a second connecting post 36, one end of the second upper arm 32 remote from the second lower arm 34 is hinged to the plug 10, and one end of the second lower arm 34 remote from the second upper arm 32 is hinged to the base 20. The screw 37 penetrates the first and second connection posts 35 and 36 and is screwed with the first and second connection posts 35 and 36, respectively.

The first and second connection posts 35 and 36 can be moved toward and away from each other as the screw 37 rotates. Taking the first upper support arm 31 and the second upper support arm 32 as an example, when the first connecting post 35 and the second connecting post 36 are close to each other, the included angle between the first upper support arm 31 and the screw rod 37 and the included angle between the second upper support arm 32 and the screw rod 37 are gradually increased, and the vertical distance from one end of the first upper support arm 31 and the second upper support arm 32, which is far away from the screw rod 37, to the screw rod 37 is gradually increased because the lengths of the first upper support arm 31 and the second upper support arm 32 are unchanged, so as to drive the top 10 to move along the preset telescopic direction towards the direction far away from the base 20, thereby realizing the lifting of the vehicle. Similarly, the vertical distance from the end of the first lower support arm 33 and the second lower support arm 34 away from the screw 37 to the screw 37 is gradually increased, and, because the base 20 is usually disposed on the ground or other objects that are not easy to move, the first lower support arm 33 and the second lower support arm 34 also drive the plug 10 to move along the preset telescopic direction in a direction away from the base 20, so as to realize lifting of the vehicle. When the first connecting post 35 and the second connecting post 36 are away from each other, the vertical distance from the end of the first upper arm 31, the second upper arm 32, the first lower arm 33 and the second lower arm 34 away from the screw 37 to the screw 37 is gradually reduced, and the plug 10 is driven to move along the preset telescopic direction towards the direction approaching the base 20, so as to put down the vehicle.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
