The utility model discloses an one of the purpose adopts following technical scheme to realize: the utility model provides a bear slide guide rail with worm structure, including guide rail, a plurality of with guide rail sliding connection's bear the slide, guide rail one side is equipped with the transmission worm, bear one side of slide be equipped with transmission assembly that the transmission worm meshed.
Furthermore, one side of bearing the slide is equipped with the locating piece, drive assembly includes driving roller and pulley, and driving roller fixed connection is on the locating piece, the pulley cover locate the driving roller outside, and can with the meshing of transmission worm.
Further, a connecting arm is arranged between each bearing sliding seat, and two ends of each connecting arm are respectively hinged with two adjacent bearing sliding seats;
and the connecting arm comprises a flexible part and connecting sections positioned at two ends of the flexible part.
Further, the transmission worm is provided with an external thread, and the cross section of the external thread is of a rectangular structure;
and the diameter of the pulley is smaller than the thread pitch of the external thread.
Further, the transmission worm is meshed with at least two pulleys.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the driving mode of a chain or a synchronous belt is replaced by the transmission worm, and the characteristics of stable, sustainable or intermittent transmission of worm transmission are utilized, so that the running stability of the bearing sliding seat is improved, bidirectional transmission can be realized, and the self-locking effect can be achieved when the bearing sliding seat is static.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a bearing slide 2 and guide rail 1 with a worm structure comprises a guide rail 1 and a plurality of bearing slides 2 slidably connected with the guide rail 1, wherein a transmission worm 3 is arranged on one side of the guide rail 1, and a transmission assembly meshed with the transmission worm 3 is arranged on one side of the bearing slides 2. The operation of the driving worm 3 can be driven by a motor, and the description of the embodiment is omitted.
One side of bearing slide 2 is equipped with locating piece 41, plays the connection effect, and drive assembly includes driving roller 42 and pulley 43, and driving roller 42 fixed connection is on locating piece 41, and the pulley 43 cover is located the driving roller 42 outside, and can mesh with transmission worm 3. When the transmission worm 3 rotates, the pulley 43 is pushed to carry out linkage of the bearing sliding seat 2, the central axis of the transmission worm 3 and the central axis of the pulley 43 are designed on the same horizontal plane, the moving direction of the side surface of the external thread 31 is the same as the rotating direction of the pulley 43, when the pulley 43 is pushed, friction between the pulley 43 and the side surface of the external thread 31 is reduced through rotation of the pulley 43, and the service life is prolonged.
All be equipped with the linking arm between each bears the slide 2 and be used for the linkage, the both ends of linking arm articulate two adjacent bearing the slide 2 respectively, are convenient for adjust the direction when turning to. In this embodiment, the connecting arm includes a flexible portion 52 and connecting sections 51 located at two ends of the flexible portion 52, and the middle flexible portion 52 may be made of a rubber material, so that when the carriage 2 turns, the resistance generated when the carriage 2 turns can be reduced by elastic deformation of the middle flexible portion.
Since the driving worm 3 has the external thread 31, the cross section of the external thread 31 is designed to be a rectangular structure in the embodiment, and the external thread is fully contacted with the side surface of the pulley 43, so that the stability of the transmission is ensured. Trapezoidal threads can be adopted, the structure of the pulley 43 is adjusted, and the pulley is designed to be in a circular truncated cone shape and fully abutted against the side face of the external thread 31.
In order to make the pulley 43 have a certain moving space in operation, the diameter of the pulley 43 is smaller than the thread pitch of the external thread 31, and the pulley 43 also has an axial moving space on the transmission roller 42, and the length of the transmission roller 42 should be larger than the thickness of the pulley 43.
