As shown in fig. 1 to 4, a working support for jacking comprises a base 1, a station seat 2, a telescopic support 3, four auxiliary supports 4 and a limit stop ring 5; the station seat 2 is provided with a seat hole 6 connected with an external medicine hopper, and a connecting beam 7 is arranged between any two sides of the seat hole 6; one end of the telescopic support 3 is connected with the base 1, the other end of the telescopic support is connected with the connecting beam 7, and the bottom of the telescopic support 3 is provided with power equipment 8; the auxiliary supports 4 are distributed around the telescopic supports 3 in an annular array, one end of any one auxiliary support 4 is connected with the base 1, and the other end of the auxiliary support 4 is connected with the station seat 2; the limit stop ring 5 penetrates into the telescopic support 3 and is in one-to-one correspondence and connection with the auxiliary support 4 through a plurality of connecting rods 9.
In the present embodiment, four auxiliary supports 4 are distributed in an equilateral triangle on the outside of telescopic support 3, thereby providing a suitable supporting force for station base 2. Of course, in different embodiments, there may be four auxiliary frames 4, or five or more auxiliary frames 4, and it should be understood that, no matter how many auxiliary frames 4 are required to be uniformly distributed on the outer side of the telescopic frame 3, so that the auxiliary frames 4 can provide uniform supporting force to avoid the telescopic frame 3 from deflecting due to the non-uniform force provided by the auxiliary frames 4.
It should be noted that the limit stop ring 5 can slide in the length direction of the entire telescopic bracket 3, that is, the inner diameter of the limit stop ring 5 is larger than the maximum outer diameter of the telescopic bracket 3.
For better use of the present embodiment, any one of the auxiliary stands 4 includes a first stand 10 and a second stand 11; the first support 10 is of a hollow structure, one end of the first support is connected with the station seat 2, and the other end of the first support is not closed; the second bracket 11 extends into the first bracket 10 and is connected with the first bracket 10 in a sliding way; one end of the second bracket 11, which is far away from the first bracket 10, is connected with the base 1; an elastic part 12 is arranged between the top end of the first bracket 10 and the top end of the second bracket 11.
In any one of the auxiliary brackets 4, the elastic member 12 provided therein needs to maintain the same elasticity, and thus, in some embodiments, a pressure sensor is provided at any one end of the elastic member 12, thereby measuring whether the elastic force of the elastic member 12 is maintained uniformly or within an error allowable range. This ensures that any one of the elastic elements 12 provides a uniform support force for the work station carrier 2 in the operating state.
For better use of the present embodiment, the inner side of the first bracket 10 is provided with two sliding grooves 13; a sliding block 14 corresponding to the sliding groove 13 is arranged on the outer side of the second bracket 11; any one of the slide grooves 13 is slidably connected to its corresponding slide block 14.
In the present embodiment, the two sliding grooves 13 are symmetrically arranged, so that the second bracket 11 is provided with two sliding blocks 14, which are also symmetrically arranged. Of course, in other embodiments, the number of the sliding grooves 13 may be three, or four, or more, but it is necessary to ensure that the sliding grooves 13 should be uniformly arranged on the inner side of the first bracket 10, so as to provide a proper limit condition for the second bracket 11. Besides, in the embodiments in which only one sliding groove 13 is provided on the inner side of the first bracket 10, the arrangement can also achieve the appropriate sliding performance, but the arrangement makes the sliding of the second bracket 11 unstable, and it is not ensured that the second bracket 11 is kept in the vertical state.
As shown in fig. 5, for better use of the present embodiment, any one of the sliders 14 is provided with at least one roller 15; any one of the rollers 15 is slidably connected to the corresponding slide groove 13. In this embodiment, since there is a sliding relationship between the roller 15 and the sliding groove 13, the second bracket 11 can be slid relatively to the first bracket 10 according to the expansion and contraction of the telescopic bracket 3.

Either the small tray 16 or the large tray 17 can be connected to the second bracket 11 or the telescopic bracket 3 by means of a screw thread. For the small tray 16, an external thread is arranged at one end, close to the small tray 16, of the second support 11, a blind hole is formed in the middle of the small tray 16, and an internal thread is arranged in the blind hole, so that the small tray 16 can be installed by connecting the external thread with the internal thread. The large tray 17 may be similar to the small tray 16, or the blind holes may be changed to through holes, and screws may be inserted through the large tray 17 and into the telescopic bracket 3 to connect the large tray 17 and the telescopic bracket.
For better use of the present embodiment, the base 1 is provided with a mounting groove 18; the power equipment 8 is arranged in the mounting groove 18; the telescopic bracket 3 extends into the mounting groove 18 to be connected with the power equipment 8.
In a specific using process, when the telescopic bracket 3 is in the shortest state, the elastic parts 12 are in a compressed state, and at the moment, the four elastic parts 12 indirectly provide supporting force for the station seat 2 at four positions; when the telescopic bracket 3 is in the longest state, the elastic part 12 is still in a compressed state, and can indirectly provide supporting force for the station seat 2; in the two states, the four elastic members 12 have a synergistic relationship, but one of the four elastic members is not enough, and the work station seat 2 can be inclined when the elastic force of any one of the four elastic members 12 fails and is insufficient; the solution to this drawback is to provide as many auxiliary brackets 4 as possible, so that when the elastic force of any one of the elastic members 12 fails or is insufficient, the elastic members 12 on both sides can share the elastic force loss, thereby preventing the work station seat 2 from tilting. The number of the elastic members 12 is at least three.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
