Abstract

The utility model discloses a rotary plastic stool which comprises a stool plate and stool legs, wherein a central hole is formed in the stool plate; a rotary seat is arranged on the stool plate; a central shaft is arranged at the bottom of the rotary seat and is inserted into and connected with a central hole of the stool plate; an annular boss is arranged at the periphery of the central hole in the top surface of the stool plate; a circle of boss is arranged on the bottom surface of the rotary seat and close to the periphery of the central shaft; when the central shaft is inserted into and connected with the central hole, the annular boss is matched with the boss; a circle of round groove coaxial with the central hole is formed in the stool plate and close to the edge of the stool plate; a plurality of rotary clamping tongues matched with the round groove are arranged at the bottom of the rotary seat; and the lower ends of the clamping tongues are contained in the round groove. According to the rotary plastic stool, the area of contact between the rotary seat and a seat plate is reduced, an anti-side-slip structure is added, and the problems of large friction force, high noise and easy side slip of an existing rotary stool are solved.

Description

Rotary plastic stool

Technical field

The utility model relates to a kind of stool, specifically a kind of rotary plastic stool.

Background technology

It is a lot of that plastic stool is used in daily life, generally comprises stool face and stool pin, and stool face and stool pin are mostly integrated; Also have in order to use more flexible, plastic stool is improved, if Granted publication number is the patent of CN 202365332U, disclose a kind of rotation bathing stool, comprise stool plate and stool pin, on stool plate, be provided with seat board, the central shaft of seat board bottom is plugged in the centre bore of stool plate, when having a bath, object of nursing can be sitting in seat board and arbitrarily rotates health, facilitates nurse's nursery work; But the contact area of this design seat board and stool plate is large, and frictional force is large, the noise of rotation rings, in addition, only depend on central shaft and centre bore to coordinate location, the structure of anti-sideslip not, easily there is displacement and likely the cooperation of central shaft and centre bore impacted in seat board and stool plate.

Utility model content

For overcoming the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of rotary plastic stool, reduces contact area and has increased the structure of anti-sideslip, the problem that frictional force is large, noise rings, easily breaks away that solves existing rotating stool.

For realizing above-mentioned technology, adopt following technical scheme to realize:

A kind of rotary plastic stool, comprise stool plate and stool pin, on stool plate, have a centre bore, on stool plate, be also provided with rotating seat, the bottom of rotating seat is provided with central shaft, and central shaft is plugged in the centre bore of stool plate, it is characterized in that: at stool plate top surface centre bore, be provided with annular boss around, bottom surface at rotating seat is also provided with a circle boss by the peripheral place of central shaft, and in the time of in central shaft is plugged on centre bore, annular boss matches with boss; The described stool plate position that keeps to the side is provided with the circle circular groove coaxial with centre bore, and described rotating seat bottom is provided with the rotation block tongue that several circular grooves coordinate, and the lower end of block tongue is contained in circular groove.

The lateral wall of the bottom of described central shaft is provided with card muscle, and in the time of in central shaft is plugged on centre bore, the lower port that card muscle is connected to centre bore prevents hole, central shaft off center.

When the utility model rotating seat is connected with stool plate, except being located at the annular boss of stool plate top surface, contact with being located at rotating seat bottom surface boss, remainder is unsettled, and contact area reduces can reduce the noise producing in rotary course; In addition, in order to prevent that rotating seat and stool plate from breakking away, the some rotation block tongues that arrange in rotating seat bottom coordinate with the circular groove that is located at stool plate, can increase the stability that rotating seat is connected with stool plate.

Fig. 2 is decomposing schematic representation of the present utility model;

Fig. 3 is another decomposing schematic representation of the present utility model;

Fig. 4 is profile of the present utility model.

The specific embodiment

As Figure 1-4, the utility model discloses a kind of rotary plastic stool, comprise stool plate 1 and stool pin 2, on stool plate 1, have a centre bore 11, on stool plate 1, be also provided with rotating seat 3, the bottom of rotating seat 3 is provided with central shaft 31, central shaft 31 is plugged in the centre bore 11 of stool plate, at stool plate 1 end face centre bore, be provided with annular boss 12 around, bottom surface at rotating seat is also provided with a circle boss 32 by the peripheral place of central shaft 31, in the time of in central shaft 31 is plugged on centre bore 11, annular boss 12 matches with boss 32; The described stool plate position that keeps to the side is provided with the circle circular groove 13 coaxial with centre bore, and described rotating seat bottom is provided with the rotation block tongue 33 that several circular grooves 13 coordinate, and the lower end of rotation block tongue is contained in circular groove.

When the utility model rotating seat is connected with stool plate, except being located at the annular boss of stool plate top surface, contact with being located at rotating seat bottom surface boss, remainder is unsettled, and contact area reduces can reduce the noise producing in rotary course; In order to prevent that rotating seat and stool plate from breakking away, the some rotation block tongues that arrange in rotating seat bottom coordinate with the circular groove that is located at stool plate, can increase the stability that rotating seat is connected with stool plate.

In addition, on the lateral wall of the bottom of central shaft 31, be provided with card muscle 34, in the time of in central shaft is plugged on centre bore, the lower port that card muscle 34 is connected to centre bore prevents hole, central shaft off center, further improve rotating seat and the stability that stool plate is connected, use safer.

Claims
