Title:
MECHANICAL LIMITING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/259359
Kind Code:
A1
Abstract:
A mechanical limiting mechanism, comprising a rotating seat (2), a spring arm (3), a carrier portion (4), and a reinforcing arm (5). The spring arm (3), the rotating seat (2), the reinforcing arm (5), and the carrier portion (4) constitute a four-link mechanism. The spring arm (3) and the reinforcing arm (5) are limited by means of the contact between the spring arm (3) and the reinforcing arm (5), and a change in the height of limiting is achieved by adjusting the size of the spring arm (3) and/or the size of the reinforcing arm (5). When the spring arm (3) and the reinforcing arm (5) drive the carrier portion (4) to move downward, the spring arm (3) and the reinforcing arm (5) abut against one another, and then the four-link mechanism cannot rotate any more, thereby achieving mechanical limiting, which can prevent the carrier portion (4) from falling. In addition, no additional parts need to be added, and different limiting heights can be achieved merely by adjusting the size of the spring arm (3) and/or the size of the reinforcing arm (5). Moreover, the described mechanism is convenient to use and simple in structure.
