Problems solved by technology

[0002] At present, whether it is on the drawer or on the limit of the rotating frame, the button is used to make it out of the limit, which is very inconvenient to operate
Some environments require a reliable limit position, which will inevitably increase the steel of the compression spring, which is difficult to achieve by pressing it by hand.

Embodiment Construction

[0011] As shown in the drawings, the frame 1 is hinged to the knob shaft 2, the outer end of the knob shaft 2 is fixed to the knob 12, the inner end of the knob shaft 2 is fixed to the right end of the crank 3, the left end of the crank 3 is hinged to the right end of the pull rod 5, and the left end of the pull rod 5 Hinged with the right end of positioning shaft 6, the positioning shaft 6 is covered with stage clip 7, the left end of positioning shaft 6 is a tapered positioning pin 8, and positioning pin 8 is inserted in the positioning groove of support 9. After the positioning pin 8 is pulled out from the positioning groove of the bracket 9, the frame 1 and the bracket 9 can move relatively.

[0012] The compression spring 7 is empty sleeved in the bushing 11, and the bushing 11 is fixed with the frame 1.

[0013] A retaining ring 10 is fixed on the frame 1 at the left end of the axle sleeve 11, and a positioning hole is arranged on the retaining ring 10, and the positioni...

Abstract

The invention relates to a limiting mechanism capable of relieving limiting through a rotate mode, wherein a rotary knob shaft is hinged with a frame; a rotary knob is fixed at the outer end of the rotary knob shaft; the right end of a crank is fixed at the inner end of the rotary knob shaft; the left end of the crank is hinged with the right end of a draw rod; the left end of the draw rod is hinged with the right end of a positioning shaft; a compression spring is sheathed on the positioning shaft; the left end of the positioning shaft is provided with a conical positioning pin; and the positioning pin is inserted into the positioning slot of a bracket. The limiting mechanism provided by the invention can relieve the limiting through the rotate mode and is convenient in operation and labor-saving.

Description

technical field [0001] The invention relates to a position-limiting mechanism that releases the position-limiting through rotation. Background technique [0002] At present, whether it is on the drawer or on the limit position of the rotating frame, the button is used to make it out of the limit position, which is very inconvenient to operate. Some environments require a reliable limit, which will inevitably increase the steel of the compression spring, which is difficult to achieve by pressing it by hand. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention provides a position-limiting mechanism, which can release the position-limiting mechanism through rotation, and is easy to operate and labor-saving. [0004] The technical scheme adopted by the present invention to solve its technical problems is: hinge the knob shaft on the frame, fix the knob at the outer end of the knob shaft, fix the right end of the cra...
