Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Such as figure 1 , 2 As shown, the present invention provides a link mechanism, which includes: a link bracket 1 , a pituitary assembly 2 , a compression spring 3 , and a sheave 4 .

[0022] The link bracket 1 is used to connect two pituitary assemblies 2 , specifically, the link bracket 1 is capable of pivotal movement, and the link bracket 1 takes an axis vertically passing through its center as a rotation axis. At the same time, the connecting rod ...

Abstract

The invention provides a connecting rod mechanism. The connecting rod mechanism comprises a connecting rod bracket, vertical body modules and a compression spring; the connecting rod bracket uses an axle vertically penetrating through self center as a rotating shaft; waist holes are formed in the connecting rod bracket; two waist holes are provided, and are distributed around the center in a central symmetry mode; two vertical body modules are correspondingly provided; any vertical body module comprises a vertical body, and a pin shaft connected to the vertical body; the vertical bodies are slidingly connected into the waist holes through the pin shafts thereof; the compression spring sleeves one rod member; a fixed gasket sleeves the rod member, and is positioned at one end of the compression spring; a breach is formed in the edge of the connecting rod bracket; and the fixed gasket extends into the breach. In the connecting rod mechanism, the two vertical body modules are connected through the connecting rod bracket, and the motion synchronism of the vertical body modules is further guaranteed through the compression spring; and the connecting rod mechanism is simple in structure,excellent in synchronism and lower in cost.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a link mechanism suitable for speed governors. Background technique [0002] The speed limiter is one of the safety control components in the elevator safety protection system. When the elevator is in operation, the car may overspeed for any reason, and there is even a danger of falling. At this time, after the main engine fails, the speed limiter of the elevator safety component will work, and the linkage lifting structure will linkage with the safety gear to stop the car (counterweight) on the guide rail. [0003] Specifically, when the existing overspeed governor operates, the two pituitary assemblies of the sheave device perform centrifugal motion as the speed increases, and the two pituitary assemblies must perform centrifugal movement outward synchronously. In order to satisfy the synchronous outward movement of the two pituitary assemblies, it is necessary to add a con...
