Technical Field

[0001] The utility model relates to the technical field of jacks, in particular to a hydraulic jack which is easy to disassemble and install. Background Art

[0002] A hydraulic jack is a jack that uses a plunger or hydraulic cylinder as a rigid lifting member. It has the characteristics of compact structure, stable operation, strong lifting force, and self-locking. The working principle of a hydraulic jack is to use oil as the working medium, transmit motion through changes in sealed volume, and transmit power through the internal pressure of the oil. The hydraulic transmission device is essentially an energy conversion device.

[0003] At present, since most of the existing hydraulic jacks are integrated structures, it is not convenient for people to disassemble them, which makes it inconvenient for people to carry and store them. In addition, the bottom area is small, and it is easy to tilt or damage the ground when subjected to greater pressure. A solution is proposed below to solve the above problems. Utility Model Content

[0009] By adopting the above technical solution, after the jack body is separated from the installation slot, the spring pushes the V-shaped lever back to its original position to prevent the V-shaped lever from rotating with the change of gravity during the transportation of the installation plate, thereby increasing the number of frictions and reducing the service life of the equipment.

[0010] Preferably, semicircular grooves are formed at both ends of the tool groove.

[0011] By adopting the above technical solution, the semicircular groove makes it convenient for the staff to take out the rocker from the tool slot.

[0012] Preferably, the rocker is a multi-stage telescopic rod.

[0013] By adopting the above technical solution, the multi-stage telescopic rod makes the joystick longer when in use, which is more labor-saving, and can be retracted and stored in the tool slot when not in use.

[0014] Preferably, a handle is fixedly connected to the side of the jack body.

[0015] By adopting the above technical solution, the handle is used to drive the jack body, which is convenient for disassembly, installation and transfer.

[0016] Preferably, a wristband is fixedly connected to one end of the mounting plate.

[0017] By adopting the above technical solution, the wristband facilitates the movement of the mounting plate.

[0018] Beneficial effects: 1. A mounting plate is connected to the lower end of the jack body, and the mounting plate is used to increase the contact area with the ground, thereby preventing the ground from being damaged or the jack from tilting when the jack body is under pressure.

[0019] 2. The jack body and the mounting plate are connected by a V-shaped lever and an arc-shaped pressure plate. The clamping force is provided by the jack body's own gravity and the pressure it is subjected to, avoiding the use of screws and other connection methods, making the overall installation and disassembly greatly convenient.

[0020] 3. A tool slot is provided on the mounting plate to store the rocker, thus preventing the rocker from being lost after being separated from the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
