Description

Linked lifting mast

This creation is related to the lifting mast, especially for a linked lifting mast.

Most of the lifting masts are used to be mounted on a vehicle, and can be extended upwards if necessary to raise the top to a high position, and can be further condensed downward to lower the top end thereof to make the vehicle easy to move. Lifting masts are widely used, such as fire and disaster relief lighting equipment, mobile communication stations, news interview vehicles, etc., all of which need to be smoothly extended upwards and downwards by lifting the mast device antenna or other lines.

The conventional lifting mast is formed by sequentially arranging a plurality of inner diameter increasing tubes. When the lifting mast is extended upward, the tube systems are sequentially moved upward to overlap only a tube adjacent to the lower side thereof to a small distance. Maintaining the connection between the two; in other words, the lifting mast moves to its top dead center position in turn, until the lifting rods are stretched to the longest position when all the tubes are moved to their top dead center positions. And let its top rise to the highest point. Similarly, when the lifting mast is condensed downward, it moves downwardly to its bottom dead center position until all the tubes move to the bottom dead center position, and the lifting mast is condensed to the shortest The top is lowered to the lowest point. Therefore, the lifting process of the conventional lifting mast takes a relatively long time, which is inconvenient to use and thus needs to be improved.

In view of the above-mentioned shortcomings, the main purpose of the present invention is to provide a linkage type lifting mast, in which each tube system moves at the same time, so that the lifting speed is faster.

In order to achieve the above object, the interlocking lifting mast provided by the present invention comprises: a bottom component having a base, a supporting pipe body connected to the base, and a rotatably disposed on the base and located at the base An active rod supporting the inside of the tube; a first moving component, a first moving base body screwed to the active rod, a first moving pipe body connected to the first moving seat body, and a rotatably disposed on the first moving seat body and located at the first Moving the first hollow rod body in the tube body, the first moving component can be linearly moved in the support tube body by the active rod, and the first hollow rod system can be rotatably sleeved by the active rod And the second moving component has a second moving body screwed to the first hollow body, and a second moving pipe body connected to the second moving body, the first The second moving component is disposed in the first moving tube body by the first hollow rod body and linearly moved. Thereby, when the active rod rotates, the first moving component and the second moving component move up or down at the same time, so that the linked lifting mast is extended or shortened, so the lifting speed of the interlocking lifting mast is very fast. .

The detailed construction, features, assembly or use of the linked lifting masts provided by this creation will be described in the detailed description of the subsequent embodiments. However, those of ordinary skill in the art should understand that the detailed description and specific embodiments of the present invention are merely used to illustrate the present invention and are not intended to limit the scope of the patent application.
