Abstract

The utility model discloses a turning board stool which comprises two brackets and a fixing shaft fixedly mounted between the two brackets; a movable turning board is mounted on the fixing shaft; a position block is installed on the fixing shaft; the position block is provided with a hinge shaft; and a pneumatic suspension bar is mounted between the upper part of the movable turning board and the hinge shaft. When the stool is in use, the upper part of the pneumatic suspension bar rotates as the movable turning board is changed towards horizontality, and a piston within the pneumatic suspension bar can gradually compress the air inside the pneumatic suspension bar to generate certain potential energy; and when the stool is no longer in use, propelled by the pneumatic suspension bar, the movable turning board rotates into vertical state. As the potential energy of air pressure propels the movable turning board to perform rotation, the speed at which the movable turning board bounces can be reduced, and the sound of the rebounding movable turning board can be avoided. Moreover, the pneumatic suspension bar is convenient to detach and repair without making abnormal noise. The turning board stool has the advantages of simple structure and convenient operation, and is particularly suitable for application in a sleeping compartment of a train.

Description

The turnover panel stool

Technical field

The utility model relates to a kind of turnover panel stool of collision sound can reduce stool and dig the time.

Background technology

The structure of the turnover panel stool that people are common is such: an end of stool is penetrated with fixed axis, and torsion spring is installed on the fixed axis, and torsion spring one end withstands on the fixture, and the other end withstands stool; During the vertical state of stool, the elastic potential energy minimum of torsion spring, during the stool level, torsion spring is in the maximum flexibility potential energy states, and the release by the torsion spring elastic potential energy makes the stool of level be turned into vertical state.Because the torsion spring elastic potential energy discharges rapidly, and the turnover panel stool is dug fast, thereby can colliding baffle plate when being turned to vertical state, stool sends bigger sound, bumping to shorten the service life of stool; Moreover torsion spring in use between long meeting get rusty, can send different sound, allow the people feel under the weather.

The utility model content

The technical problems to be solved in the utility model provides a kind of turnover panel stool of collision sound can reduce stool and dig the time.

For addressing the above problem, a kind of turnover panel stool that is provided, comprise two stands and be packed in fixed axis between the two stands, drop in leaf is housed on the fixed axis, its design feature is: on the described fixed axis fixed block is installed, hinge is housed on the fixed block, pneumatic support bar is installed between the top of drop in leaf and the hinge.

After adopting said structure, the bottom of pneumatic support bar is installed on the hinge of fixed block, and its top is installed in the top of drop in leaf, when drop in leaf is in vertical state, and the piston extension elongation maximum in the pneumatic support bar; When people need take one's seat drop in leaf steering horizontal state, rotated thereupon on the top of pneumatic support bar, the air in the pneumatic support bar that can gradually reduce of the piston in the pneumatic support bar, thus form certain potential energy; When people left the seat, drop in leaf was turned to vertical state under the promotion of pneumatic support bar.This mode of rotating by air pressure potential energy promotion drop in leaf can reduce the speed that drop in leaf is upspring, the sound that causes when avoiding drop in leaf to dig; And pneumatic support bar is easy to remove and repair, and can not send different sound.This kind turnover panel stool is simple in structure, and is easy to operate, is specially adapted to use in the couchette compartment.

As improvement of the present utility model, the outside of described pneumatic support bar is provided with the protective cover that can flexibly connect with drop in leaf.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be among Fig. 1 A-A to structural representation.

The specific embodiment

A kind of as shown in drawings turnover panel stool, it comprises two stands 1, fixed axis 2 is housed between the two stands 1, drop in leaf 3 is contained on the fixed axis 2 by the bearing on both sides, support 1 is provided with baffle plate 8 and can limits drop in leaf 3 and can only rotate to horizontal level, and the middle part of fixed axis 2 is equipped with fixed block 4, and hinge 5 is housed on the horizontal side of fixed block 4, pneumatic support bar 6 is installed on the hinge 5, and the other end of pneumatic support bar 6 is hinged on the top of drop in leaf 3.The outside of pneumatic support bar 6 is provided with protective cover 7, is riveted on the drop in leaf 3 around the protective cover 7.

In conjunction with the accompanying drawings, this turnover panel stool is to use like this: when drop in leaf was in vertical state, the upper end of pneumatic support bar 6 was hinged on the top of drop in leaf 3, and its lower end is hinged on the hinge 5, at this moment the piston extension elongation maximum in the pneumatic support bar 6; When people need take one's seat drop in leaf steering horizontal state, rotated thereupon the upper end of pneumatic support bar 6, according to the triangle principle, and the air in the pneumatic support bar that can gradually reduce of the piston in the pneumatic support bar 6, thus form certain potential energy; When people left the seat, drop in leaf was turned to vertical state under the promotion of pneumatic support bar.
