Problems solved by technology

[0002] In the process of spherical joint movement in reality, a certain action is completed by operating a specific instrument. Usually, the action of the instrument needs to be completed by combining several individual actions. Some individual actions need to be locked to a certain extent. At present, we are all A certain action of the instrument can be kept in the existing state by means of human hand dialing, but the human hand is flexible and often swings slightly, resulting in certain actions that cannot always be kept unchanged. At this time, a locking mechanism is needed to allow The spherical joint remains locked after reaching a certain state

Embodiment Construction

[0019] A spherical joint mechanism with locking function of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0020] Such as Figure 1 to Figure 6 A spherical joint mechanism with a locking function is shown, which has a housing 1, the housing 1 is composed of left and right halves, and a spherical joint 2, a transverse guide block 3 and a longitudinal guide block are arranged inside the housing 1. The kinematic mechanism that block 4 forms and the locking mechanism that is made up of spherical joint seat 5, locking driving lever 6 and locking threaded rod 7.

[0021] The transverse guide block 3 and the longitudinal guide block 4 are semi-arc-shaped structures, the two ends of the transverse guide block 3 and the longitudinal guide block 4 are movably connected with the housing 1 and are vertically intersected, and the transverse guide block 3 and the longitudinal guide block 4 There are transverse guide groove...

Abstract

The invention belongs to a spherical joint mechanism with a locking function. The spherical joint mechanism is provided with a shell, and a moving mechanism composed of a spherical joint, a transverseguiding block and a longitudinal guiding block and a locking mechanism composed of spherical joint bases, a locking driving lever and a locking threaded rod are arranged in the shell; a bulb is arranged at one end of the spherical joint, and an operation driving lever is arranged at the other end of the spherical joint; the transverse guiding block and the longitudinal guiding block are each of asemicircular-arc structure; the two ends of the transverse guiding block and the two ends of the longitudinal guiding block are movably connected with the shell and arranged in a perpendicularly-crossed mode; the middle of the transverse guiding block and the middle of the longitudinal guiding block are provided with a transverse guiding groove and a longitudinal guiding groove respectively; andthe operation driving lever penetrates through the transverse guiding groove and the longitudinal guiding groove and then stretches out of the shell. According to the spherical joint mechanism with the locking function, the locking function is achieved through the simple mechanical structure, electronic control is not needed, and moving damping of the spherical joint can be adjusted by adjusting the distance between the two spherical joint bases.

Description

technical field [0001] The invention patent belongs to a spherical joint mechanism with a locking function. Background technique [0002] In the process of spherical joint movement in reality, a certain action is completed by operating a specific instrument. Usually, the action of the instrument needs to be completed by combining several individual actions. Some individual actions need to be locked to a certain extent. At present, we are all A certain action of the instrument can be kept in the existing state by means of human hand dialing, but the human hand is flexible and often swings slightly, resulting in certain actions that cannot always be kept unchanged. At this time, a locking mechanism is needed to allow The spherical joint remains locked after reaching a certain state. Contents of the invention [0003] In order to maintain the locked state of the spherical joint mechanism after manual operation, the invention provides a spherical joint mechanism with a lockin...
