Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Fig. 1～Fig. 8, the utility model comprises dining chair body 1, also comprise by the hinged propelling movement guide rod 2 of upper push rod and lower push rod one end 3, two steel wire rope guide rings 4 of steel wire rope, holder frame bearing support 5,7, two guide rails 8 of 6, two rollers of two back-moving springs, pedal 9, rotating shaft 10, swallow-tail form slide block 11, rubbish barrel frame 12 and swallowtail-shaped slide 13, parallel between former and later two chair inboard legs of dining chair body 1 one sides two guide rails 8 are housed, cross bar medial surface between two chair legs is equipped with cylinder, one end of the propelling movement guide rod 3 being hinged and this cylinder form revolute pair, lower end and rubbish barrel frame 12 outsides of holder frame bearing support 5 are affixed, on holder frame bearing support 5 sides, the lower cylinder that is equipped with respectively, two cylinders are provided with roller after the slotted hole through upper push rod and lower push rod respectively, two rollers lay respectively in the groove with guide rail separately, between two guide rails 8 and upper push rod and lower push rod, back-moving spring 6 is housed respectively, the chair leg bottom above that two guide rails 8 are housed has the swallowtail-shaped slide 13 that is parallel to chair pin, swallow-tail form slide block 11 1 sides coordinate with swallowtail-shaped slide 13, the flange of pedal 9 one sides embeds in swallow-tail form slide block 11 another side grooves, form revolute pair with rotating shaft 10, the top end face of pedal 9 opposite sides is provided with transverse slat, one end of steel wire rope 3 is fixed on swallow-tail form slide block 11, after the circular hole of the other end of steel wire rope 3 through steel wire rope guide ring 4 and upper push rod top, fix with lower push rod top.

As shown in Figure 1 and Figure 2, two guide rails are arranged symmetrically with about the cross bar between two chair legs.

As shown in Figure 1, Figure 2 and shown in Fig. 4, the top end face place of pedal 9 is provided with transverse slat, and toward the outer side, the width of transverse slat equals the width of pedal 9 to transverse slat.

As shown in Figure 1, Figure 2 and shown in Fig. 8, rubbish barrel frame 12 above surrounding is equipped with baffle plate, and will will be higher than the baffle plate of other three faces with the baffle plate that holder frame bearing support 5 is fixed together, the bottom surface of rubbish barrel frame 12 higher than and be parallel to dining chair leg bottom surface.

As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 6, described two back-moving springs 6 respectively one end are contained on guide rail 8, the other end is contained in and pushes on guide rod 2, and two back-moving springs 6 have certain angle respectively and between two guide rails 8.

Operation principle of the present utility model is as follows:

As shown in Fig. 1～Fig. 8, dustbin is placed on rubbish barrel frame 12, step on the transverse slat on pedal 9 tops with heel, make pedal 9 be rotated down 90 ° around rotating shaft 10.Continue to step on pedal 9, pedal 9 drives swallow-tail form slide block 11 to move downward, swallow-tail form slide block 11 pulls steel wire rope 3 downwards, steel wire rope 3 is given downward power of upper propelling movement guide rod, give one of lower propelling movement guide rod power upwards, angle between propelling movement guide rod and lower propelling movement guide rod is reduced, two back-moving springs 6 are elongated, drive holder frame bearing support 5 to travel forward by the rolling forward of two rollers 7 on two guide rails 8, holder frame bearing support 5 drives the dustbin being placed on rubbish barrel frame 12 to travel forward simultaneously.In the time unclamping pedal 9, two back-moving springs 6 pull respectively propelling movement guide rod and lower propelling movement guide rod to rotate, the upper angle pushing between guide rod and lower propelling movement guide rod becomes large, two rollers 7 roll backward respectively on two guide rails 8, thereby drive 5 motions backward of holder frame bearing support, the motion backward of holder frame bearing support 5 drives again the dustbin being placed on rubbish barrel frame 12 to move backward, and steel wire rope 3 pulls pedal 9 to move upward simultaneously.Pedal 9 is rotated up to 90 ° around rotating shaft 10 with heel.This has just completed a complete dustbin telescopic process.
