Locking device for guide rail

Abstract

The invention discloses a locking device for a guide rail. The locking device includes a bottom plate. The bottom plate is provided with a guide groove. A groove body for accommodating a slide slideris formed in the guide groove, the upper end of the groove body is provided with a limiting plate for preventing the slide slider from detaching, an elastic sheet mounting groove is formed in the limiting plate in the moving direction of the slide slider, a driving groove is formed in the limiting plate in the direction vertical to the slide slider, a friction elastic sheet for decelerating and locking the slide slider is installed in the elastic sheet mounting groove, and the elastic sheet mounting groove is provided with a driving component for driving the friction elastic sheet. By means ofthe locking device, a driving rod moves downwards to drive a driving boss to move along a driving groove, the friction elastic sheet is extruded, and therefore the volume of the groove body in the guide groove is reduced, the slide slider and the friction elastic sheet are in friction, and the aim of deceleration or locking is achieved; and lifting guiding of the driving rod is achieved through alimit buckle, driving of the driving rod is realized through a driving cylinder, and resetting of the driving rod is realized through a return spring.

Description

technical field [0001] The invention belongs to a component of a sliding structure, in particular to a locking device of a guide rail. Background technique [0002] A kinematic pair is an active connection in which two components are in direct contact and can produce relative motion. [0003] Elements such as points, lines, and surfaces in which two or more components participate in contact to form a kinematic pair are called kinematic pair elements. [0004] There are several ways to classify sports activities: [0005] Classification according to the contact form of the kinematic pair: the kinematic pair in surface-to-surface contact has a lower pressure in the contact part, which is called a low pair, while the kinematic pair in point or line contact is called a high pair, and the high pair is easier to wear than the low pair. [0006] The low pair generally has a rotating pair, a moving pair, and a screw pair, and the high pair includes wheels and rails, cams and follo...
