Example Embodiment

[0021] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0022] Such as figure 1 As shown, a fast lifting nut of the present invention includes a housing 2, a handle 3, a moving pin 5, a nut 6 and a fixing pin 7. The nut 6 is a split structure of two half-cylindrical split nuts. A fixed pin 7 and a moving pin 5 are provided. The two nuts 6 are respectively mounted on the inner round table of the housing 2 through their respective fixed pins 7, and the two nuts 6 are connected to the turntable 4 provided at the end of the housing 2 through the moving pins 5. The end cover 1 is installed on the upper part of the turntable 4; the handle 3 is arranged on the outside of the housing 2.

[0023] The thread in each nut 6 is cut in half at a clockwise position, and the remaining parts after the two nuts 6 are fastened together form two concentric arcs. The longitudinal section of the thread in the nut 6 is trapezoida...

Abstract

The invention relates to a fast lifting nut. The fast lifting nut comprises a shell, a handle, moving pins, a nut body and fixed pins; wherein, the nut body is a split structure of two cylindrical opposite-opened nuts, the fixed pin and a moving pin are arranged on the nuts, and the two nuts are mounted on an inner round table of the shell through the corresponding fixed pins; the two nuts are further connected with a rotating disc arranged at the end of the shell through the moving pins, and an end cover is mounted on the upper part of the rotating disc; and the handle is arranged at the exterior of the shell, the rotating disc is an annular plate, dialing rods are symmetrically arranged at the two ends of the annular plate, two arc grooves are formed in the rotating disc with respect tothe center of the rotating disc, linear grooves are symmetrically formed in the clockwise positions of each arc groove, the arc grooves are matched with fixed pin top end grooves, and the linear grooves are matched with the moving pins. According to the fast lifting nut, when the nuts are combined with a screw, the nuts can be lifted on the screw along the screw line, when the nuts are rotated outwards to be tangent to the shell, the nuts are not matched with the screw, meanwhile, the nuts can be lifted quickly on the screw, and the purpose of saving the time of the operator is achieved.

Description

technical field [0001] The invention relates to a nut, in particular to a fast lifting nut. Background technique [0002] The lifting nut is used on the lead screw of the heavy-duty car jack. The existing lifting nut includes a nut bracket, a sleeve, and a split nut arranged in the sleeve. The lifting nut of this structure can only be buckled and buckled along the helical line on the screw rod. Movement, the working speed is slow, the efficiency is low, and the fast lifting function cannot be realized. Contents of the invention [0003] Aiming at the disadvantages of the lifting nuts in the prior art, such as slow working speed, low efficiency, and inability to realize fast lifting function, the problem to be solved by the present invention is to provide a fast lifting nut that can be lifted quickly, is easy to operate, and has high working efficiency. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the presen...
