Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
Example 1.
As shown in fig. 1 to 2, the driving device capable of two-way expansion and contraction in this embodiment includes a pipe fitting 1 and two driving mechanisms 2, two ends of the pipe fitting 1 are provided with cavities capable of accommodating the driving mechanisms 2, the driving mechanisms 2 are fixedly disposed in the cavities at the two ends of the pipe fitting 1, the two driving mechanisms 2 are disposed in a back-to-back manner, the driving mechanism 2 includes a housing 21, a motor 22, a lead screw 23, a movable element 24, and a pipe pushing member 25, the movable element 24 is provided with a threaded hole in threaded connection with the lead screw 23, the motor 22 is fixedly connected with the housing 21, the lead screw 23 is disposed in the housing 21, the motor 22 drives the lead screw 23 to rotate, the rotation of the lead screw 23 is driven by the motor 22 and includes direct transmission and indirect transmission, the direct transmission is that the rotor of the motor 22 is directly connected with the lead screw 23, the indirect transmission is that the rotor of the motor 22 first transmits a gear, when the screw rod 23 rotates, the movable element 24 is driven to linearly move along the axial direction of the screw rod 23, so that the movable element 24 drives the pipe pushing element 25. Preferably, the movable element 24 is circumferentially limited and mounted with the shell 21, the movable element 24 is axially slidably mounted with the shell 21, and the movable element 24 is fixedly connected with the pipe pushing element 25. In this embodiment, the motor 22 of the two driving mechanisms 2 drives the screw 23 to rotate, so as to drive the pipe pushing member 25 to move, and both ends are retractable.
In this embodiment, the cavities at the two ends of the pipe 1 are communicated. Is convenient for wiring and is beneficial to manufacturing.
In this embodiment, the pipe member 1 is a circular pipe or a square pipe. When pipe fitting 1 is square pipe, actuating mechanism 2 and pipe fitting 1 can realize spacing installation in circumference.
In this embodiment, the housing 21 is provided with a mounting hole facing the radial direction of the pipe fitting 1, and the pin member 3 penetrates through the side wall of the pipe fitting 1 to fixedly connect the driving mechanism 2 and the pipe fitting 1. The pin shaft piece 3 can realize the limit installation of the driving mechanism 2 and the pipe fitting 1 in the circumferential direction and the axial direction.
In this embodiment, the pin member 3 is a rivet, a screw, or a pin.
The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
