Description

Technical Field

[0001] This utility model relates to the field of car lift technology, and in particular to a scissor lift. Background Technology

[0002] Scissor lifts use the unfolding and folding of scissor-type support frames to lift and lower cargo platforms. The power comes from the extension and retraction of hydraulic cylinders that drive the unfolding and folding of the scissor-type support frames. Its scissor-type mechanical structure allows the platform to be raised or lowered, and it is often used in lifting operations. Scissor lifts are also required in automotive professional internships and training.

[0003] Existing scissor lifts have the following shortcomings in use:

[0004] Typically, the area of ​​an existing car lift platform is fixed and cannot be expanded horizontally. If personnel need to work on the lift, the platform surface is occupied by cars, making it inconvenient for personnel to stand on the platform to work. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing car lift platform area is fixed and cannot be expanded to the left or right. When personnel need to stand on the lift to work, the platform surface is occupied by cars, making it inconvenient for personnel to stand on the platform to work. Therefore, a scissor lift is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A scissor lift for car lifts includes two platforms and two bases for supporting a car chassis. One side of each base is bolted to a common ramp that facilitates vehicle movement. There are two ramps, each located at one end of the two bases.

[0008] A lifting assembly, mounted on the base, is used to raise and lower the platform.

[0009] Extension mechanisms are set up within the platform to extend its functionality.

[0010] The fixing mechanism is set on the platform to fix the expansion mechanism.

[0011] In one possible design, the lifting assembly includes a first frame, a second frame, two second guide rails, two first guide rails, and a third hinge seat. The bottoms of the two first guide rails are welded to the top of the base, and the bottom of the third hinge seat is welded to one side of the top of the base. First rollers are rotatably connected to the bottom ends of both sides of the second frame, and the two first rollers are respectively located within the two first guide rails and are in rolling connection. A fourth hinge seat is welded to one side of the bottom of the platform. The top of the second frame is hinged to the fourth hinge seat, and the bottom of the first frame is hinged to the third hinge seat. The tops of the two second guide rails are welded to one side of the bottom of the platform. Second rollers are rotatably connected to the top ends of both sides of the first frame, and the two second rollers are respectively located within the two second guide rails and are in rolling connection. Rotary rods are fixedly installed on the inner walls of both sides of the second frame, and the ends of the two rotating rods that are close to each other are rotatably connected to the sides of the first frame.

[0012] In one possible design, the extension mechanism includes two extension plates, each with a receiving groove on one side. The bottom of the two extension plates is slidably connected to the bottom inner wall of the two receiving grooves, and a handle is welded to one side of each extension plate to facilitate its extension.

[0013] In one possible design, the fixing mechanism includes a threaded rod and a movable plate. A movable hole is provided on one side of the platform. The movable plate is L-shaped. One end of the movable plate is welded to one side of the extension plate. The movable plate is located inside the movable hole. The threaded rod is threadedly connected to the movable plate. Multiple insertion holes are provided on one side of the platform. One end of the threaded rod is inserted into the insertion hole. A knob is fixedly provided at the other end of the threaded rod to facilitate its rotation.

[0014] In one possible design, a first hinge seat is welded to one side of the first frame, and a second hinge seat is welded to the inner wall of one side of the second frame. A hydraulic cylinder is provided between the first hinge seat and the second hinge seat. The fixed part of the hydraulic cylinder is hinged to the second hinge seat, and the telescopic part of the hydraulic cylinder is hinged to the first hinge seat.

[0015] In one possible design, the ramp is provided with anti-slip grooves to increase the friction of the vehicle tires and prevent slippage.

[0016] In one possible design, a slider is fixedly provided at the bottom of the expansion plate, and a groove is provided on the bottom inner wall of the receiving groove to reduce the friction generated by the movement of the expansion plate. The bottom of the slider is slidably connected to the inner wall of the groove.

[0017] In this application, before use, the hydraulic cylinder is connected to an external hydraulic pump station to provide power, and an external controller is used for control. Initially, the platform is not raised (the platform and the top of the ramp are level). A car is slowly driven onto the ramp, using its slope to easily enter the platform. When the front and rear wheels are on the two ramps, the car stops. When personnel need to stand on the platform to work on the vehicle, they pull two handles in sequence. The movement of the handles moves the extension plate, causing it to slide within the platform's receiving groove, extending it to a suitable width. This allows the platform to be expanded, facilitating personnel to stand on the platform to work on the vehicle. After aligning the threaded rod and the insertion hole, turn the knob. The rotation of the knob drives the threaded rod to rotate, inserting one end of the threaded rod into the insertion hole, thus fixing the extension plate. When raising the vehicle, activate the hydraulic cylinder. The hydraulic cylinder starts working, and through the hinge action of the first and second hinge seats, it pushes the relative movement of the first and second frames. The first roller rolls in the second guide rail, and the second roller rolls in the first guide rail, realizing the smooth lifting and lowering of the platform. As needed, the car is raised to the required height for maintenance, inspection, or repair work. Both the platform and the extension plate are made of metal.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this utility model, the scissor lift for cars uses a lifting assembly. When the hydraulic cylinder starts working, the first hinge seat and the second hinge seat are hinged together, which pushes the relative movement of the first frame and the second frame. The first roller rolls in the second guide rail, and the second roller rolls in the first guide rail, thus achieving smooth lifting of the platform.

[0020] In this utility model, the scissor lift for cars uses an extension mechanism. By pulling two handles in sequence, the movement of the handles causes the extension plate to move, allowing the extension plate to slide within the receiving groove of the platform and be pulled out to a suitable width. This allows the platform to be extended, making it easier for personnel to stand on the platform to work on vehicles.

[0021] In this utility model, the scissor lift for cars uses a fixing mechanism. By rotating a knob, the rotation of the knob drives the rotation of a threaded rod, causing one end of the threaded rod to be inserted into the insertion hole, thereby fixing the extension plate.

[0022] In this invention, the lifting assembly enables the platform to be raised and lowered smoothly, the expansion mechanism allows the platform to be expanded, making it convenient for personnel to stand on the platform to work on the vehicle, and the fixing mechanism allows the expansion plate to be fixed.
