FOLDING STORAGE STOOL

Abstract

The utility model relates to a pneumatic brake release apparatus used on an elevator traction machine. By means of the technical solution, the air films in the air cabin are pushed by using compressed air to drive the push rod to transfer a thrust force, so that the locking arms are unfolded, and the locking brake and the brake release are implemented in a pneumatic way. Therefore, the problems in the prior art that a great amount of electric energy is consumed and the noise is difficult to eliminate can be solved, no noise is generated during operation, the safety is high, the structure is simple, and the manufacturing cost is greatly reduced.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0018] Specific embodiments of the present invention will be further described below in combination with drawings.

[0019] As shown in FIG. 1 and FIG. 2, the folding storage stool in the present embodiment comprises a folding stool body 1. After the stool body 1 is unfolded, a stool cover 2 is sleeved on an upper opening of the stool body 1. A supporting board 3 for supporting the stool body 1 is installed at a bottom of an inner cavity of the unfolded stool body 1. The stool cover 2 has a folding structure capable of being folded and comprises a plurality of sections of cover parts 201 connected mutually and folded relatively. After the cover parts 201 located at an end part are upwards folded, part of the upper opening of the stool body 1 is exposed to form a picking and placing opening 101. Generally, two cover parts 201 are arranged, i.e., a first cover part 2011 and a second cover part 2012. Upper surfaces of the first cover part 2011 and the second cover part 2012 are connected into a whole through surface fabric. The first cover part 2011 and the second cover part 2012 can be turned by 180°.

[0020] As shown in FIG. 1 and FIG. 2, a supporting back board 4 is installed at an inner side surface of one side wall of the stool body 1. The supporting back board 4 comprises two sections which can be folded relatively, i.e., a side supporting section 41 and an upper supporting section 42. The side supporting section 41 is tightly close to the inner wall of the stool body 1. The upper supporting section 42 is upwards folded relative to the side supporting section 41 and then abutted against the upwards folded cover parts 201 to obliquely support the cover parts 201 to form a back cushion.

[0021] As shown in FIG. 3 and FIG. 4, two opposite side surfaces on the stool body 1 have an inwards folded side fold 102; and a bottom surface of the stool body 1 has an inwards folded bottom fold 103. After the stool body 1 is folded along the side fold 102 and the bottom fold 103, two other side surfaces of the stool body 1 are closed; and the folded stool body 1 can be placed in the stool cover 2.

[0022] During use, the stool body 1 is unfolded and the supporting board 3 is placed at the bottom of the inner cavity of the stool body 1 to ensure that the stool body 1 is completely unfolded. The stool cover 2 is covered at the opening after the stool body 1 is unfolded. The cover parts 201 at one end are folded and the formed picking and placing opening 101 can be used for directly picking and placing the articles. The cover parts 201 are folded so that the cover parts 201 are in an oblique state. The supporting back board 4 after upwards folded is abutted against the cover parts 201. The oblique cover parts 201 are in a shape of a backrest, so as to support a human back.
