Preferably, the base and the lifting seat are both connected with a rotation stopping structure.

Preferably, the rotation stopping structure is a polygonal guide post, and the base and the lifting seat are provided with polygonal guide holes matched with the polygonal guide post.

Preferably, the polygonal guide post is provided with a limiting structure, and the limiting structure limits the base and the lifting seat to be separated from the polygonal guide post.

Preferably, the limiting structure is a boss, and the boss is detachably connected and installed at two ends of the polygonal guide column;

the outer end of the base and the outer end of the lifting seat are both provided with counter bores matched with the bosses.

Preferably, a channel is arranged in the center of the adjusting piece, and threads with opposite turning directions are arranged on the inner walls of two ends of the channel;

and the outer walls of the base and the lifting seat are provided with threads with opposite rotation directions.

Preferably, the outer end of the base and the outer end of the lifting seat are both provided with platforms.

Preferably, the outer side wall of the adjusting piece is provided with a hexagonal structure.

The utility model discloses an useful part lies in:

1. by utilizing the structure, when the adjusting piece rotates relative to the base, the lifting seat and the support cannot rotate relative to each other, so that the damage to the contact surface of the support is reduced.

2. The utility model utilizes the thread structure with opposite rotation directions, the speed of the lifting seat driven by the rotation of the adjusting piece is twice of that of the traditional supporting top, and the adjusting speed is improved.

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a supporting top device, including adjusting part 1, threaded connection has base 2 and lift seat 3 respectively at adjusting part 1 both ends, and supporting top device sets up in the supporter bottom, and when adjusting part 1 rotated relative base 2 and lift seat 3, base 2 and lift seat 3 can relative movement, and then the support height of adjustment supporter, because base 2 and lift seat 3 are relative movement, consequently more traditional supporting top structure, the translation rate has promoted the twice to the speed of adjustment has been improved.

In order to prevent the adjusting piece 1 from rotating and drive the base 2 and the lifting seat 3 to rotate, the base 2 and the lifting seat 3 are both connected with a rotation stopping structure, the rotation stopping structure is preferably set to be a polygonal guide post 4, polygonal guide holes are formed in the base 2 and the lifting seat 3 and are matched with the polygonal guide post 4, however, in the actual use process, two ends of a supporting and jacking device are respectively abutted against a supporting object and the ground under the influence of the gravity of the supporting object, the friction force of the contact surfaces of the end parts of the base 2 and the lifting seat 3 is far greater than the force of the adjusting piece 1 for driving the base 2 and the lifting seat 3, and therefore, the lifting seat 3 is different from the traditional supporting and jacking structure in that the lifting seat 3 is lifted through rotation.

The arrangement of the polygonal guide post 4 can reduce the problem that the base 2 and the lifting seat 3 are driven to rotate by the rotation of the adjusting part 1 due to the light weight of a support, and when the supporting height is adjusted, only the base 2 needs to be fixed, so that the lifting seat 3 can only move up and down.

In order to avoid the polygonal guide column 4 from being separated from the base 2 and the lifting seat 3, the polygonal guide column 4 is provided with a limiting structure, and the limiting structure can limit the base 2 and the lifting seat 3 from being separated from the polygonal guide column 4. Limit structure specifically establishes to boss 5, and boss 5 demountable connection installs 4 both ends of polygon guide post, 2 outer ends of base with all be equipped with counter bore 6 and the cooperation of boss 5 on the 3 outer ends of lift seat, the counter bore 6 size is greater than the polygon guiding hole, and in the middle of this embodiment, polygon guide post and polygon guiding hole all establish to square structure.

The center of an adjusting piece 1 is provided with a channel, a structure similar to a sleeve is adopted, the inner walls of two ends of the channel are provided with threads with opposite turning directions, the outer walls of a base 2 and a lifting seat 3 are provided with threads with opposite turning directions, namely, for example, the base 2 is provided with a left-handed external thread, and a left-handed internal thread is arranged below the adjusting piece 1; the lifting seat 3 is provided with a right-handed external thread, and a right-handed internal thread is arranged above the adjusting piece 1.

In addition, the outer end of the base 2 and the outer end of the lifting seat 3 are preferably provided with platform structures, so that the contact area is increased, and the outer side wall of the adjusting part 1 is preferably of a hexagonal structure, so that the adjusting part is convenient to be matched with a wrench.

The specific working principle of the utility model is as follows:

the utility model is put between a supported object and a platform, the adjusting piece 1 is rotated by a wrench, and due to the threaded structures with opposite rotation directions at two ends of the adjusting piece 1, on one hand, the base 2 and the lifting seat 3 are driven to move in the height direction, and on the other hand, the wrench rotates the adjusting piece 1 for one circle, and the moving height of the lifting seat 3 is twice of the moving height of the traditional supporting seat of the supporting top which rotates for one circle.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should also be understood that various alterations, modifications and/or variations can be made to the present invention by those skilled in the art after reading the technical content of the present invention, and all such equivalents fall within the protective scope defined by the claims of the present application.
