Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rotation and lifting stool, and when people sits on stool time, stool just can not rotate, and uses comfortable.
For achieving the above object, the utility model provides following technical scheme: a kind of rotation and lifting stool, comprise base, stool face, stool face is provided with lifting screw, described base is provided with nut, described lifting screw is arranged in nut, it is characterized in that: described base is provided with movable chamber, described nut shaft is arranged in movable chamber to slip, the end of nut is provided with some elastic claws, described elastic claw is provided with spigot surface, described base is provided with and coordinates with spigot surface and elastic claw to be pressed to the driving conical surface of lifting screw, the spring upwards propped up by nut is provided with in described movable chamber.
The utility model is set to further: described elastic claw is positioned at the lower surface of nut, and the described driving conical surface is positioned at the bottom in movable chamber.
The utility model is set to further: described elastic claw is positioned at the upper surface of nut, and elastic claw extends movable chamber, and the top in movable chamber is provided with end cap, and the described driving conical surface is positioned on end cap.
The utility model is set to further: described elastic claw is provided with slipmat towards the face of lifting screw, and described slipmat is provided with anti-skidding lines.
Compared with prior art, the beneficial effects of the utility model are: between nut and base, circumference is fixing, between bottom nut and movable chamber, there is gap, nut can in movable chamber axial slip, and supported by spring, when people sits on stool face time, spring is compressed, nut declines, elastic claw on nut declines with nut, relative slippage is there is in the elastic claw made with the driving conical surface, elastic claw is pressed to lifting screw, make phase mutual friction between elastic claw with lifting screw, when people accomplishes on stool face time, by the frictional force between elastic claw and lifting screw, avoid rotating freely of stool face, people are sat more comfortable.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model rotation and lifting stool embodiment is described further.
A kind of rotation and lifting stool, comprise base 1, stool face 2, the structure of base 1 has a lot, the present embodiment adopts 11 bendings of many metallic rod to form base 1, the upper one end of metallic rod 11 is provided with foot pad 12, and for supporting, the other end is welded to each other, in order to increase the structural strength of base 1, many metallic rod 11 are welded on reinforcing ring simultaneously; The shape in stool face 2 can be arbitrary geometry, the present embodiment preferably adopts circle, circular stool face 2 center be provided with lifting screw 3, base 1 is provided with nut 4, lifting screw 3 is arranged in nut 4 among the process in rotating stool face 2, and lifting screw 3 and nut 4 cooperatively interact, and realize rising and the reduction in stool face 2, thus adapt to the crowd of different height, and different application scenario.
Base 1 is provided with movable chamber 14, lifting screw 3 runs through movable chamber 14, the axial slip of nut 4 be arranged in movable chamber 14, namely nut 4 can not rotate in movable chamber 14 inner circumferential, slippage that only can be axial, for achieving this end, the outline of cylindrical nuts 4 is so long as not revolving body, only need by identical with the outline of nut 4 for the wall in movable chamber 14, other mode arranges axial track on nut 4 with the chamber wall in movable chamber 14, the circumference that namely can limit nut 4 is rotated, the slip of nut 4 axis can be ensured again, spring 6 is provided with between the bottom in movable chamber 14 and nut 4, when stool face 2 does not have by too large external force, nut 4 can be propped up by spring 6, and when people sits on stool face 2 time, nut 4 declines, nut 4 is made to be connected to the bottom in movable chamber 14, there is the bottom support nut 4 in movable chamber 14, the top in movable chamber 14 is provided with end cap 15 simultaneously, for carrying out spacing to nut 4.
The end of nut 4 is provided with some elastic claws 5, several elastic claw 5 circumferences are arranged on the end face of nut 4 uniformly, elastic claw 5 is provided with slipmat 52 towards the face of lifting screw 3, for increasing frictional force, further, slipmat 52 also can arrange anti-skidding lines, the side of elastic claw 5 lifting screw 3 is dorsad provided with spigot surface 51, wherein elastic claw 5 has two kinds of set-up modes
One, elastic claw 5 is arranged on the below of nut 4, the bottom in movable chamber 14 is provided with the driving conical surface 16 cooperatively interacted with spigot surface 51, the bottom in movable chamber 14 is provided with the spring base coaxial with lifting screw 3, for fixing spring 6, the conical surface 16 is driven to arrange with on spring base, when people sits on stool face 2 time, nut 4 declines under the effect of lifting screw 3, thus elastic claw 5 declines with nut 4, spigot surface 51 on elastic claw 5 is extruded mutually with the guiding conical surface bottom movable chamber 14, thus elastic claw 5 is pressed to lifting screw 3, by lifting screw 3 embracing tightly, thus avoid the rotation of lifting screw 3, like this, time people accomplishes on stool face 2, stool face 2 just can not be rotated freely, be seated more comfortable, also dodge to waist under avoiding unconscious situation simultaneously.
Two, elastic claw 5 is positioned at the top of nut 4; elastic claw 5 is through end cap 15; extend movable chamber 14; drive the conical surface 16 to be arranged on end cap 15, among the process that elastic claw 5 declines with nut 4, the driving conical surface 16 on the spigot surface 51 of elastic claw 5 and end cap 15 extrudes mutually; realization is held tightly; because elastic claw 5 exposes, in order to safety, the periphery of elastic claw 5 is provided with protective cover 7.
Nut 4 is roughly 2cm with the gap bottom movable chamber 14, and time such people accomplishes on stool face 2, can't feel and significantly decline, the inclined-plane of guide part is roughly 45 ° simultaneously, when people stands up time, ensures that spring 6 resets normally.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
