Description

Reversible seat based on sheave and chain wheel linkage

Technical Field

The utility model relates to a seat in park, especially a seat can overturn.

Background

With the further expansion of the scale of social public construction, more and more parks are convenient for people to relax and entertain, the seats in the parks also become visible basic public facilities everywhere, most of the seats in the parks or the street sides can be utilized on one side, if the seats are in rainy days or are contaminated by pedestrians carelessly, and if sanitation workers do not clean the seats timely, the seats can influence the use of the later pedestrians, so that the inconvenience is brought to the pedestrians who need the seats urgently.

In order to enable the public chair to exert the maximum application of the public chair and bring convenience to people for rest and use, the grooved wheel is rotated to drive the chain wheel to rotate, so that the surface of the chair can be overturned, the surface of the chair is fixed by utilizing the characteristic of the intermittent mechanism of the grooved wheel, when one side is not clean, the other side can be overturned at any time, and the public chair can be greatly convenient for people to use and rest, has a simple structure, is convenient and quick to use, and is suitable for being applied to public facilities in production on a large scale.

Disclosure of Invention

The utility model aims to provide a seat can overturn based on sheave and sprocket linkage, this seat that can overturn simple structure, convenient to use is swift, is fit for being applied to in the production of communal facility on a large scale.

The purpose of the utility model can be realized through the following technical scheme:

the reversible seat based on the linkage of the grooved wheel and the chain wheel comprises a seat, a grooved wheel module, a transmission module and a linkage module, wherein the grooved wheel module is connected with the linkage module through the transmission module, the transmission module transmits intermittent rotary motion of the grooved wheel in the grooved wheel module to the linkage module, and the transmission module is connected with the surface of the seat and used for overturning the surface of the seat.

The grooved wheel module comprises a handle and a grooved wheel, wherein the grooved wheel is connected with the handle and used for converting the whole-circle rotation of the handle into intermittent motion, and converting the two-time handle rotation into 180-degree rotation of the grooved wheel by utilizing the intermittent motion characteristic of the grooved wheel.

The transmission module comprises two chain wheels and a chain, wherein one chain wheel is coaxially connected with the grooved wheel, the other chain wheel is coaxially connected with the chain wheel of the linkage module, and the two chain wheels are in transmission connection through the chain.

The linkage module comprises four chain wheels and chains, shafts of the four chain wheels are respectively connected with one ends of four battens on the surface of the seat, the other ends of the battens are connected with a rotatable shaft, the four chain wheels are connected through the chains and used for transmitting the rotation of one chain wheel to the other three chain wheels, and the chain wheels drive the battens on the surface of the seat through the rotation of the shafts, so that the four battens on the surface of the seat can be turned.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the seat in the traditional sense is improved, double surfaces are available, and the use efficiency is improved.

(2) The chain wheel transmission mechanism is adopted, so that slipping cannot occur in the motion transmission process, the structure is compact, the efficiency is high, and the chain wheel transmission mechanism can work in the environment with high humidity.

(3) Simple structure and convenient operation.

Drawings

fig. 2 is a schematic structural view of a sheave module;

fig. 3 is a schematic diagram of the transmission module and the linkage module.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 to 3, a reversible seat based on a sheave and sprocket linkage comprises:

the sheave module 1 converts the rotation of the two handles into 180-degree rotation of the sheave by using the intermittent motion characteristic of the sheave;

the transmission module 2 is connected with the sheave module 1 and the linkage module 3 and is used for transmitting intermittent movement of the sheave and transmitting the rotation of the sheave to the linkage module 3;

and the linkage module 3 is connected with the transmission module 2 and is used for overturning the surface of the seat.

The sheave module 1 includes: the handle 1-1 and a power generating device of the whole system are used for transmitting the rotation of the handle 1-1 to the whole system; the grooved wheel 1-2 is connected with the handle 1-1 and is used for converting the whole-circle rotation of the handle 1-1 into intermittent motion;

the transmission module 2 comprises: a sprocket coaxial with the sheave 1-2; a chain wheel coaxial with the chain wheel of the linkage module 3, and a matching chain for connecting the two chain wheels together;

the linkage module 3 includes: four identical chain wheels, the shafts of which are connected with the wooden strips 4 on the surface of the seat and are used for controlling the overturning of the surface of the seat; the chain is connected with four chain wheels and is used for transmitting the rotation of one chain wheel to other three identical chain wheels, and the rotation of the shaft drives the wooden strip on the surface of the chair, so that the aim of overturning the surface of the chair is fulfilled.

When the surface of the chair needs to be turned over, the handle is rotated for two circles, the corresponding grooved wheel rotates for 180 degrees, the grooved wheel rotates to drive the transmission chain wheel, the transmission chain wheel transmits power to the linkage chain wheel through the chain, the other end of the batten 4 on the surface of the chair is fixed through the rotatable shaft, the rotation of the four same chain wheels enables the batten on the surface of the chair corresponding to the chain wheel to be turned over, the other end of the batten is fixed through the rotatable shaft, and the whole device achieves power transmission through the chain and the chain wheel.
