[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a traffic signal light pole that can be raised and lowered. Figure 1-3A liftable traffic signal light pole comprises a mounting base 1, the mounting base 1 comprises a mounting cylinder 101 for mounting on the ground, two support rings 102 are mounted in the mounting cylinder 101, a support cylinder 2 is rotatably mounted in the support ring 102, a moving cylinder 3 is slidably mounted on the upper end of the support cylinder 2, the moving cylinder 3 comprises a connecting cylinder 301 slidably mounted in the support cylinder 2, a spiral rod 303 is mounted on the lower end of the connecting cylinder 301, a lifting assembly 4 for driving the moving cylinder 3 to slide along the support cylinder 2 is mounted on the inner side of the support cylinder 2, a bracket 103 is welded on the inner side of the lower support ring 102, a spiral notch for use with the spiral rod 303 is opened in the middle of the bracket 103, which is used to realize that the spiral rod 303 passes through the bracket 103 and then drives the spiral rod 303 and the connecting cylinder 301 to rotate, thereby driving the support cylinder 2 to rotate relative to the mounting base 1;

[0023] By adopting the above technical solution, the threaded rod 401 is driven to rotate by the driving motor 5, thereby driving the connecting tube 301 to move up and down. When the connecting tube 301 moves down to the position of the bracket 103, the spiral rod 303 passes through the bracket 103 and will rotate in a spiral manner, thereby causing the driving spiral rod 303 and the connecting tube 301 to rotate, thereby driving the supporting tube 2 to rotate relative to the mounting base 1, so that after the connecting tube 301 is fully retracted, the signal light cross bar has rotated horizontally, thereby preventing the signal light cross bar from affecting traffic.

[0024] Reference Figure 2 The lifting assembly 4 includes a plurality of threaded rods 401 rotatably mounted on the mounting base 1 , a transmission wheel 402 is mounted at the lower end of the threaded rod 401 , and the four transmission wheels 402 are connected by a transmission belt, so that the threaded rod 401 can rotate synchronously while reserving wiring space.

[0025] Reference Figure 3 A movable plate 302 is fixedly mounted on the lower end of the connecting tube 301, the threaded rod 401 passes through the movable plate 302 and is threadedly connected to the movable plate 302, the spiral rod 303 is located in the middle of the movable plate 302, and a plurality of reserved slots are opened on the inner side of the movable plate 302 to reserve wiring space.

[0026] Reference Figure 2 , threaded holes are provided on the support tube 2 and the mounting tube 101, and locking bolts 6 are installed in the threaded holes. After the spiral rod 303 is separated from the bracket 103, the threaded holes on the support tube 2 and the mounting tube 101 are coaxial, and the position is locked by the locking bolt 6 to prevent rotation.

[0027] The implementation principle of a liftable traffic signal light pole in the embodiment of the present application is as follows: the mounting tube 101 is fixed to the ground, at which time the direction of the crossbar on which the signal light is mounted is perpendicular to the direction in use, and the threaded rod 401 is driven to rotate forward by the driving motor 5, thereby causing the movable plate 302 to drive the connecting tube 301 and the screw rod 303 to move upward. During this process, the screw rod 303 spirally rises relative to the bracket 103, so that the screw rod 303 is separated from the bracket 103. At this time, the support tube 2 is rotated exactly ninety degrees, so that the threaded hole on the support tube 2 and the mounting tube 101 are coaxial, and the locking bolt 6 is passed through the threaded hole to lock the mounting tube 101 and the support tube 2 in position. At this time, the driving motor 5 drives the threaded rod 401 to continue rotating The connecting tube 301 moves to a suitable height and stops when it is inspected and maintained. The temporary signal light is used to temporarily operate the connecting tube 301 to avoid affecting the urban traffic. The locking bolt 6 on the supporting tube 2 is released and the threaded rod 401 is driven to reverse by the driving motor 5 to move the connecting tube 301 downward. When the connecting tube 301 moves downward to the position of the bracket 103, the spiral rod 303 passes through the bracket 103 and rotates in a spiral direction, thereby causing the driving spiral rod 303 and the connecting tube 301 to rotate, thereby driving the supporting tube 2 to rotate relative to the mounting base 1, so that after the connecting tube 301 is fully retracted, the signal light cross bar has rotated horizontally to avoid the signal light cross bar affecting the traffic.
