DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0027] like Figures 1-6 As shown, a vehicle lift includes: a lifting platform 1, a scissor frame 12 for driving its lifting displacement is installed at the bottom of the lifting platform 1, and a drive cylinder 121 for driving its lifting action is installed on the scissor frame 12. The drive cylinder 121 can be a pneumatic cylinder or a hydraulic cylinder. The scissor frame 12 drives the lifting platform 1 to lift displacement through the drive cylinder 121.

[0028] Mounting base 11 is distributed on the outer side of lifting platform 1. In this embodiment, there are four mounting bases 11, which are distributed at the four corners of lifting platform 1. The mounting base 11 can be fixed to lifting platform 1 by bolts. Support arm 2 and roller 4 are pivotally mounted on the mounting base 11. The roller 4 is fixed to the lower end of support arm 2 by pin 41. A pull rod 15 is installed at one end of lifting platform 1. The multiple rollers 4 and pull rod 15 cooperate with each other to facilitate the movement and transfer of this embodiment. When the scissor frame 12 retracts until the roller 4 touches the ground, the lifting platform 1 can be dragged freely on the ground to move to any position to lift the vehicle.

[0029] The support arm 2 is equipped with a support platform 3 for supporting the vehicle. The support platform 3 can have various height specifications and models. The support platform 3 is used to abut against the chassis reinforcing ribs of the vehicle when the lifting platform 1 lifts the vehicle, so as to lift the vehicle more stably.

[0030] The lifting platform 1 is provided with a through groove 13, which allows workers to more conveniently repair and maintain the bottom of the vehicle. A hopper 14 is detachably installed on the through groove 13, which can be used to hold the vehicle's waste, such as waste engine oil.

[0031] The support arm 2 corresponds one-to-one with the mounting base 11 and is horizontally rotatably mounted on the mounting base 11. The support arm 2 is pivotally connected to the mounting base 11 via a rotating shaft 112. The outer end of the support arm 2 is equipped with a handle 24 that can drive it to rotate. Thus, in this embodiment, the support arm 2 can be rotated along the rotating shaft 112 by pulling the handle 24, thereby adjusting the position of the support arm 2 and the roller 4.

[0032] The support arm 2 is provided with a clamping plate 23 capable of displacement and clamping limiting the mounting seat 11, so as to clamp the mounting seat 11 through the clamping plate 23 mounted on the support arm 2, and then limit the rotation of the support arm 2. Specifically, the mounting seat 11 is fixed with a gear 111, and the clamping plate 23 is slidingly installed on the support arm 2 and is provided with a tooth groove 231 capable of engaging with the gear 111.

[0033] Further, when the scissors frame 12 lifts the lifting platform 1, the clamping plate 23 on the support arm 2 can move away from the clamped mounting seat 11, so that the support arm 2 can be rotated and attached to the side edge of the lifting platform 1, thereby reducing the floor area of the lifting platform 1 in use. The structure of the embodiment is simple, the production cost is low, the transfer use is more convenient, the vehicle can be lifted flexibly in temporary places such as outdoors, and the practicality is good.

[0034] In order to improve the reliability of the clamping and limiting of the support arm 2, the support arm 2 is provided with a waist-shaped groove 21 and a sliding plate 22 capable of being driven to slide along the waist-shaped groove 21. The waist-shaped groove 21 extends towards the mounting seat 11 side, the sliding plate 22 is connected to the clamping plate 23 through the waist-shaped groove 21, and the clamping plate 23 is guided to displace along the length direction of the waist-shaped groove 21, so that the tooth groove 231 on the clamping plate 23 can be driven to engage or move away from the gear 111.

[0035] Further, in the process of adjusting the position of the clamping plate 23 with the support arm 2, the tooth groove 231 can be driven to engage with the gear 111 to position the rotation of the support arm 2, and when the lifting platform 1 moves and transfers through the support arm 2 and the roller 4, the tooth groove 231 of the clamping plate 23 can be stably engaged and fixed on the gear 111, thereby ensuring the flexibility and reliability of the connection and fixation of the support arm 2.

[0036] The support arm 2 is provided with a cylinder 221 installed in the internal cavity of the support arm 2, and the driving end of the cylinder 221 is connected to the sliding plate 22. The cylinder 221 drives the sliding plate 22 to reciprocatingly slide, so as to drive the clamping plate 23 to clamp the mounting seat 11, thereby realizing the rotation positioning of the support arm 2.

[0037] The support arm 2 is provided with a valve 25 capable of driving the cylinder 221 to act. The valve 25 is controlled to drive the cylinder 221 to act by pulling or pressing the valve 25. As an optimization, the valve 25 can be arranged on the handle 24, so that when the handle 24 is pulled, the cylinder 221 can be more conveniently driven to act through the valve 25, thereby facilitating the rotation or positioning operation of the support arm 2.

[0038] The above merely describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
