Example Embodiment

[0011] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0012] figure 1 As shown, a mechanical self-locking hydraulic jack includes a cylinder block 1, a high-pressure connector 2, a piston rod 3, a cylinder head 4, and a lock nut 5. The bottom wall of the cylinder block 1 is provided with a high-pressure joint 2 communicating with the inner cavity of the cylinder. The bottom of the piston rod 3 is sealed and slidably arranged in the inner cavity of the cylinder block 1. The top of the piston rod 3 is sealed and slidably connected to the cylinder head 4, and the cylinder head 4 is enclosed On the top of the cylinder block 1, the outer wall of the cylinder block 1 is movably screwed with a lock nut 5 through threads.

[0013] figure 2 As shown in another embodiment of the present invention, a mechanical self-locking hydraulic jack includes a cylinder block 1, a high pressure connector 2, a piston rod 3, a cylinde...

Abstract

The invention discloses a mechanical self-locking hydraulic jack. A locking nut is movably connected to the outer wall of a cylinder block of a traditional jack in a screwed mode through threads, and under the jacking action of the jack, the locking nut is matched to go up and down along the thread on the outer wall of the cylinder block so as to achieve the supporting function. The mechanical self-locking hydraulic jack is simple and compact in structure, firm and stable in connection, convenient, rapid and safe to use and operate, and suitable for meeting the requirement for the double actions of jacking and supporting on various occasions.

Description

technical field [0001] The invention relates to a jack, in particular to an eccentric load jack capable of double functions of lifting and supporting. Background technique [0002] In the prior art, precise lifting and lifting in a very narrow space, its closed height and maximum formation are the primary factors, so jacks are required. However, since the jack itself mainly relies on external pressure to lift, it does not have a long-term support function. It cannot be used in some occasions that need to be supported for a period of time to facilitate subsequent work. If the jack is taken out after being supported by another support device, its operation Difficult, safety risk is big, put in jack again when lowering again, there is bigger risk of use equally. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a mechanical self-locking hydraulic jack with simple and compact structure, convenient manufacture and us...
