In the figure, 1, a base, 2, a cushion, 3, a backrest, 4, a cushion spring, 5, a supporting rod, 6, a wedge block, 7, a connecting column, 8, a pin shaft, 9, a backrest spring, 10 and a sponge.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
As shown in fig. 1-2, the seat for the mini-tiller comprises a base 1, a seat cushion 2 and a backrest 3, wherein the seat cushion 2 and the backrest 3 are arranged on the base 1, the seat cushion 2 is connected with the base 1 through a seat cushion spring 4, the backrest 3 is fixed with the base 1 through a waist support assembly, and the waist support assembly comprises a supporting rod 5, a wedge block 6 and a plurality of connecting columns 7 which are arranged side by side, and in the embodiment shown in fig. 2, the number of the connecting columns 7 is five. The support rod 5 has two, two support rods 5 set up respectively in the both sides of base 1, spliced pole 7 sets up between two support rods 5, and each spliced pole 7 is connected with support rod 5 through same round pin axle 8, round pin axle 8 wears to establish on each spliced pole 7 and support rod 5, the one end and the base 1 of support rod 5 are fixed, the other end of support rod 5 is rotated through round pin axle 8 and each spliced pole 7 and is connected, every spliced pole 7 respectively is connected with back 3 through a back spring 9, each spliced pole 7 still passes through voussoir 6 interconnect, the inclined plane of voussoir 6 is towards cushion 2, the side of cushion 2 towards voussoir 6 is the inclined plane.
In order to make the operator sit more comfortable, the seat cushion 2 and the backrest 3 are provided with a sponge 10.
The working principle of the utility model is as follows:
as shown in fig. 1, the seat cushion 2 and the backrest 3 are perpendicular to each other in the unstressed condition. When an operator sits on the cushion 2 of the mini tiller, the cushion 2 is stressed to downwards press the cushion spring 4, so that the cushion 2 descends, the cushion 2 is attached to and abutted against the inclined surface of the wedge block 6 towards the inclined surface of the wedge block 6, and the wedge block 6 is pressed downwards. After the wedge blocks 6 are pressed down, as the wedge blocks 6 are positioned on the connecting columns 7, and the connecting columns 7 are connected with the supporting rods 5 through the pin shafts 8, each connecting column 7 rotates around the pin shafts 8, as shown in fig. 1, each connecting column 7 rotates anticlockwise, and each connecting column 7 drives the backrest springs 9 and the backrest 3 to incline towards the direction of the cushion 2. Since the magnitude of rotation of each connecting post 7 depends on the descending magnitude of the seat cushion 2, the larger the weight of the operator is, the larger the magnitude of pressing down the seat cushion 2 is, and the larger the magnitude of rotation of each connecting post 7 is, the larger the inclination magnitudes of the backrest springs 9 and the backrest 3 are; the smaller the weight of the operator, the smaller the magnitude of the depression of the seat cushion 2, the smaller the magnitude of the rotation of each link post 7, and the smaller the inclination of the backrest springs 9 and the backrest 3. For the same backrest spring 9, the pressure of a person with larger weight on the backrest 3 is larger, and the elastic deformation of the backrest spring 9 is definitely larger, the structure of the utility model can enable the connecting column 7 connected with the backrest spring 9 to incline in advance, and the larger the weight is, the larger the inclination angle of the connecting column 7 is, so that the structure is suitable for the larger elastic deformation caused by the compression of the backrest spring 9 by the person with larger weight, the backrest is not more obvious for the person with heavier weight, the backrest shaking amplitude caused by shaking of the mini tiller is reduced, and the same comfortable experience can be brought for the person with different weight. The operator leans back towards the backrest 3 to press and deform the backrest spring 9 backwards, but because the backrest spring 9 and the backrest 3 incline in advance, the backrest spring 9 cannot lean backwards due to the backward pressing of a heavy person, and after sitting stably, the swing amplitude of the backrest spring 9 along with a mini-tiller can be relatively reduced, so that the comfort level is improved. The wedge blocks 6 not only can enable the backrest 3 to incline, but also enable the backrest springs 9 to be stressed in parallel due to the fact that the connecting columns 7 are connected with each other, so that the pressure of a single backrest spring 9 is reduced, the backrest spring 9 cannot lose functions due to excessive deformation, and the service life of the backrest spring 9 is prolonged.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
