Technical Field

[0001] This utility model relates to the field of lifting pole technology, specifically a lifting pole transmission mechanism with directional function. Background Technology

[0002] An electric lifting pole is an emergency rescue lifting device driven by a motor and made of high-strength aluminum alloy. It is mainly used for nighttime rescue and communication lighting support at the scene of natural disasters and emergencies. In the prior art, the electric lifting pole supports the communication lighting device at the top, which is flat and lacks fixing measures. This makes the communication lighting device at the top unstable and prone to falling. Therefore, those skilled in the art have provided a lifting pole transmission mechanism with directional function to solve the problems mentioned in the background art. Utility Model Content

[0009] As a further embodiment of this utility model: a sliding groove is provided on the top of the top plate, and two sliding blocks are slidably connected to the bottom inner wall of the sliding groove. Springs are fixedly connected to the sides of the two sliding blocks that are far apart from each other, and the ends of the two springs that are far apart from each other are fixedly connected to the inner walls of the two sides of the sliding groove respectively.

[0010] As a further improvement of this utility model: the top of the top plate, the second lifting tube, and the first lifting tube are all symmetrically connected with two through holes, and the through holes are arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] A communication lighting device can be placed between multiple sliding blocks and clamping plates. At that time, the multiple clamping plates and sliding blocks will move closer to each other through the elastic force of the springs on both sides to clamp and fix the communication lighting device. After starting the first motor and the second motor, the first drive screw and the second drive screw can be rotated respectively. After the first drive screw rotates, it will drive the first lifting tube to rise. At that time, the first lifting tube will simultaneously drive the second lifting tube to rise together. When the second drive screw rotates, it can drive the second lifting tube and the top plate to rise simultaneously. At that time, the height of the top plate can be adjusted layer by layer by the first motor and the second motor.

[0013] This utility model is simple to use. By starting the first motor and the second motor, the height of the top plate can be adjusted layer by layer. Multiple limit blocks pass through multiple sliding holes to guide the rising first and second lifting tubes. Multiple clamping plates and sliding blocks can clamp and fix the communication lighting device by the elastic force of the springs on both sides, thereby stabilizing the communication lighting device and preventing it from falling off the top plate.
