An elastic push-pull limit mechanism

Abstract

The invention relates to an elastic push-and-pull limiting mechanism. A limiting block is installed on the upper surface of the back side of a base; an elastic mechanism and a movable crowbar for ejecting out the elastic mechanism are further installed on the base; three slots are formed in the base, three round holes correspondingly communicated with the slots are formed in the lateral face of the base, a spring ejection rod is installed in each round hole, an ejection block is arranged in each slot, and each spring ejection rod is connected with the corresponding ejection block through a spring; a through groove is formed in each ejection block, a connecting shaft penetrates the three through grooves, and handles are installed at the two ends of the connecting shaft respectively; the front end of the movable crowbar is horizontal, the back end of the movable crowbar cocks, and a circular arc transition structure is adopted at the position between the front end and the back end; the connecting shaft drives the ejection blocks to backwards move by backwards pulling the handles, the springs are stretched, the connecting shaft will be in contact with the circular arc transition structure of the movable crowbar so as to be ejected; and the connecting shaft is limited and positioned through the limiting block, and the ejection blocks are ejected through the movable crowbar. According to the elastic push-and-pull limiting mechanism, the lever principle is adopted for achieving the motion of controlling popup of the elastic mechanism.

Description

[0001] Technical field: [0002] The invention relates to the field of limit mechanism equipment, and more specifically relates to an elastic push-pull limit mechanism that uses the principle of leverage to realize the action of controlling the ejection of an elastic mechanism. [0003] Background technique: [0004] The existing push-pull mechanism generally uses a cylinder to drive the push rod to realize the ejection and reset of the push block. The equipment is large and the structure is relatively complicated. The drive device is used, which increases the production cost. In some special occasions, due to the limited space, This kind of push-pull mechanism cannot be applied, so it is necessary to design a mechanism that is small in size, does not use a driving device, and only adopts a simple mechanical structure to realize push-pull, so as to meet people's more needs. [0005] Invention content: [0006] The purpose of the present invention is to provide an elastic push-...

[0004] The existing push-pull mechanism generally uses a cylinder to drive the push rod to realize the ejection and reset of the push block. The equipment is large and the structure is relatively complicated. The drive device is used, which increases the production cost. In some special occasions, due to the limited space, This kind of push-pull mechanism cannot be applied, so it is necessary to design a mechanism that is small in size, does not use a driving device, and can be pushed and pulled with a simple mechanical structure to meet more needs of people.
