Automatic lifting high jump rod

Abstract

The invention discloses an automatic lifting high jump rod which comprises secondary sand injection bases, wherein secondary main support rods are fixedly mounted on outer surfaces of the middles of upper ends of the secondary sand injection bases; buffer protection mechanisms are arranged inside the secondary main support rods; containing tying devices are fixedly mounted on outer surfaces of onesides of the secondary main support rods; first transverse rod drag racks are arranged on outer surfaces of the middles of the upper ends of the secondary main support rods. Due to adoption of the containing tying devices, the secondary main support rods can be fastened and contained with first main support rods, then a telescopic index transverse rod can be withdrawn when the high jump rod is used by people next time, the length of the telescopic index transverse rod can be reduced, the space occupied by the high jump rod can be reduced, and convenience can be brought to people in containing; due to adoption of the buffer protection mechanisms, the compression of counteraction force of threads to a lifting working motor can be reduced, the service life of the lifting working motor can beprolonged, and the high jump rod can be used conveniently by people.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to an automatic lifting high jump pole. Background technique [0002] An automatic lifting high jump pole is a marking pole used for high jumps that can be automatically raised and lowered. It is easy to use and has been widely used. The requirements are also getting higher and higher. [0003] In the process of use, an automatic lifting high jump pole can complete the following operations: the internal motor can be used to rotate through the conductive threaded rod, and the high jump can be raised or lowered by the mutual force between the threads. for people's use. [0004] Although the existing automatic lifting high jumping pole is simple in structure and easy to use, it has a single function. The existing automatic lifting high jumping pole cannot change the length of the index bar during use, which has certain inconvenience. This kind of automatic lifting high jumping pole c...

Problems solved by technology

[0004] Although existing a kind of automatic lifting high jump bar is simple in structure, easy to use, but function is single, and existing a kind of automatic lifting high jump bar can not change the length of indicator bar during use, has certain inconvenience, and existing one This kind of automatic lifting high jumping pole cannot fasten and store the two lifting support rods together during the working process, which has certain adverse effects. When the existing automatic lifting high jumping pole is in use, the internal threaded rod cannot be connected to the external connection of the motor. The rotating shaft plays a protective role as a buffer support, which has certain adverse effects. For this reason, we propose an automatic lifting high jump pole
