Abstract

The invention discloses a folding and unfolding table, and belongs to the field of furniture and utensils. A table plate of the table can be folded upwards to downwards, and occupies small space so as to avoid damage caused by heavy pressure. According to the technical scheme, the table comprises a square flitch, the table plate, lifting lugs and pin shafts. The left and right lifting lugs are symmetrically arranged on the vertical middle of the flitch. The two lifting lugs are movably connected with the table plate through the pin shafts. A clamping groove is formed in a rectangular portion which is cut off at the middle thickness portion from the end face of the front edge, close to the flitch, of the table plate. The cut-off portion becomes a clamping plate. The clamping plate is embedded into the clamping groove, and the front end of the clamping plate horizontally stretches outwards. The end face of the stretching-out end is machined into a circular arc shape, and a transverse groove matched with the circular arc shape is machined in the portion, making contact with the flitch, of the clamping plate. A plurality of pairs of corresponding spring holes are machined in the end face of the rear end of the clamping plate and the bottom of the clamping groove. Springs are arranged inside the spring holes. The folding and unfolding table is applicable to being used and assembled in the small space.

Description

Folding and unfolding teapoy

Technical field

The invention belongs to furniture apparatus field, specifically refer to a kind of folding and unfolding teapoy.

Background technology

Retractable form is often designed to the desk people compared with device in narrow space; the common mode of packing up upwards starts to pack up; set level again during use to be convenient for people to put article; such as on train train for convenience of traveled teapoy; but; due to the environment for use relative complex of this kind of teapoy; heavier article are often put on the table by part passenger; the phenomenon of damaging teapoy by pressure is much; so be sought after a kind of teapoy not only can upwards packed up but also can pack up in actual life downwards; it should be easy to use, has the function of self-protection.

Summary of the invention

Object of the present invention provides a kind of new technical scheme of furniture apparatus a kind of folding and unfolding teapoy, and it can eliminate above-mentioned problem, avoids damage.

Technical scheme of the present invention is achieved in that it comprises square pasting board, table and hanger, bearing pin, about described hanger each symmetrical mounting pasting board up and down in the middle of, be connected to table by bearing pin activity between two hangers; On table near pasting board while be that the part that the end face on from then on limit, front starts to cut away in the middle part of its thickness one piece of rectangle forms draw-in groove, the part be cut then becomes clamp, clamp embedding draw-in groove is interior and front end level is overhanging, and overhanging one end end face is processed into arc-shaped and its pasting board position touched processes the transverse concave groove matched with it together; The rear end end face of clamp with draw-in groove bottom land is processed with corresponding several to spring hole, in spring hole, device has spring.

The invention has the beneficial effects as follows and table just can be allowed downwards upwards to pack up or pack up by shirtsleeve operation, take up room damage less that it also avoid because can't bear weight.

accompanying drawing illustrates:

Fig. 1 is that the design's folding and unfolding teapoy of illustrating is in the general assembly left side view (zoomed-in view containing clamp, draw-in groove, groove and spring, spring hole) of using state.

Fig. 2 is front view.

Fig. 3 is top view.

Fig. 4, Fig. 5 upwards start pack up and put down the left side view packed up downwards.

In each figure, 1 is pasting board, and 2 is hanger, and 3 is table, and 4 is bearing pin, and 5 is groove, and 6 is clamp, and 7 is draw-in groove, and 8 is spring hole, and 9 is spring.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 shows, folding and unfolding teapoy comprises square pasting board 1, table 3 and hanger 2, bearing pin 4, the each symmetrical mounting of hanger about 2 pasting board 1 up and down in the middle of, be connected to table 3 by bearing pin 4 activity between two hangers, pasting board is fixed on the wall of device teapoy by screw; On table 3 near pasting board 1 while be the part that the end face on the from then on limit, front of table starts to cut away in the middle part of its thickness one piece of rectangle, space after cutting away forms draw-in groove 7, it is rectangular, the part be cut then becomes clamp 6, clamp 6 to embed in draw-in groove 7 and the overhanging part of front end level, overhanging one end end face is processed into arc-shaped, and its pasting board position touched processes the transverse concave groove 5 matched with it together; The rear end end face of clamp 6 and the bottom land of draw-in groove 7 are processed with corresponding several to spring hole 8, in spring hole, device has spring 9, the diameter in spring hole is slightly narrower than the diameter rugosity of spring, the rear and front end of spring can firmly clamp spring hole by this, while giving the outside elastic force of clamp one, also can limit the relative position of clamp and table, better play the function of the design.As shown in Figure 1, horizontal table plate face can meet the needs putting lighter items, such as food, fruit, beverage one class, under the acting in conjunction of the Elastic Contact of the groove on bearing pin and table front end clamp and pasting board, table is in a metastable state, and now, the elastic force of spring can make cambered surface and the groove tight clamping fit of clamp front end, can not depart from easily, this is the stable guarantee condition that provides that it and bearing pin keep table jointly; Upwards can start to pack up after using and also can saggingly pack up, as shown in Figure 4, Figure 5, when on the table having too heavy article to be put into be in using state, table saggingly can droop too and cannot use, and this type of teapoy of undirected lower packing up function can be avoided by this to occur because of the situation of the damage that can't bear the heavy load.

Claims

1. a folding and unfolding teapoy, it comprises square pasting board, table and hanger, bearing pin, about it is characterized in that described hanger each symmetrical mounting pasting board up and down in the middle of, be connected to table by bearing pin activity between two hangers; On table near pasting board while be that the part that the end face on from then on limit, front starts to cut away in the middle part of its thickness one piece of rectangle forms draw-in groove, the part be cut then becomes clamp, clamp embedding draw-in groove is interior and front end level is overhanging, and overhanging one end end face is processed into arc-shaped and its pasting board position touched processes the transverse concave groove matched with it together; The rear end end face of clamp with draw-in groove bottom land is processed with corresponding several to spring hole, in spring hole, device has spring.
