Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a lifting mast, which aims to solve the problem that the nut sleeve and the rod body seat are easily caused by a certain impact force between the nut sleeve and the rod body seat during the ascent process of the existing lifting mast. Wear and tear, and will also produce a larger noise problem

Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0032] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0033] In addition, the ...

The invention relates to the technical field of lifting devices, in particular to a lifting mast. The lifting mast comprises a screw rod, a nut sleeve, a rod body seat and a first buffer member; the nut sleeve is threadedly connected with the screw rod and has a first surface and a second surface that are perpendicular to the axis of the screw rod, and the first surface is located above the secondsurface; the rod body seat sleeves the screw rod and is provided with a cavity; the nut sleeve is located inside the cavity; and the first buffer member is located inside the cavity and is tightly pressed between the inner wall of the cavity and the first surface. During a lifting process, the screw rod is rotated, and the nut sleeve is lifted up and down along the axial direction of the screw rod to drive the rod body seat to be lifted up and down, thereby lifting a carrier to a designated position. By arranging the first buffer member, on the one hand, the first surface of the nut sleeve isprevented from directly contacting the rod body seat, and on the other hand, the impact force between the nut sleeve and the rod body seat is buffered by the first buffer member during the lifting process, thus effectively preventing the wear of the nut sleeve and the rod body seat, and also reducing noises.
Description
technical field [0001] The invention relates to the technical field of lifting devices, in particular to a lifting mast. Background technique [0002] The lifting mast is a lifting device that is powered by compressed air, electricity, manpower, etc. to lift or lower the carrier to a certain height. It is widely used in fire protection, security, meteorology, communications, military and other industries. Compared with manual lifting masts and pneumatic lifting masts, electric lifting masts are more and more popular because they can automatically lift or lower the carrier and do not need to consider sealing issues. [0003] The electric lifting mast generally includes a screw rod, a nut sleeve and a rod body seat. When lifting or lowering the carrier, turn the screw, and the nut sleeve rises or falls along the axial direction of the screw to drive the rod body seat to rise or fall, thereby lifting or lowering the carrier to the designated position. However, during the asce...
