[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the present invention provides a semi-pressure release mechanism 100 for a spring cradle, which includes a handle 1, a cradle body 2, a roller 3, a roller pin 4, a handle shaft 5, a locking block 6, a locking block shaft 7, a locking block pin 8, a cradle seat 9, a cradle shaft 10, a pressure connector 11, and an upper roller 12.

The handle 1 passes through handle shaft 5 with cradle body 2 is connected, cradle body 2 passes through cradle shaft 10 with cradle seat 9 is connected, handle 1 can wind handle shaft 5 is rotatory and can drive cradle body 2 winds cradle shaft 10 is rotatory. The handle shaft 5 and the rocker shaft 10 are firmly riveted at two ends to prevent loosening. The handle 1 is in a long strip shape, and a handle sleeve 13 is arranged at one end of the handle, which is far away from the cradle body 2. The cradle body 2 is also in a long strip shape, and the cradle body 2 is in a hollow structure so that other parts are arranged inside the cradle body 2.

The roller 3 is fixed at one end of the handle 1 through the roller pin 4, and the roller 3 can rotate around the roller pin 4. In assembly, the roller 3 is placed in the middle of the handle 1, and then the roller pin 4 is inserted into the corresponding hole, so that the roller 3 can rotate around the roller pin 4 and both ends of the roller pin 4 are firmly fastened to prevent it from falling off.

The locking block 6 is fixed in the middle of the cradle seat 9 through the locking block shaft 7 and the locking block pin 8, during assembly, the locking block 6 is arranged in the middle of the cradle seat 9, then the locking block shaft 7 and the locking block pin 8 are respectively inserted into corresponding holes of the two parts, and two ends of the locking block shaft 7 and the locking block pin 8 are firmly riveted, so that the locking block 6 is fixed and prevented from rotating. Referring to fig. 5 again, the locking block 6 includes a first arc surface a and a second arc surface B that are respectively closely attached to the roller 3, and specifically, the first arc surface a is connected to the second arc surface B. When the spring cradle is in a locking working state, the roller 3 is tightly attached to the locking block 6 at the first arc surface A, the handle 1 is lifted, and the roller 3 goes over a first dead point on the locking block 6; when the spring cradle is in a semi-pressure release state, the included angle between the handle 1 and the cradle body 2 reaches a preset angle R, and the roller 3 and the locking block 6 are tightly attached to the second arc surface B. In summary, in the two locking states of the spring cradle, the cradle body 2 is at different angles to the horizontal plane in fig. 1, and the tension of the spring in the pressure connector 11 is different, so as to provide different pressures to the bottom roller 14.
