the user can compress the garbage by treading the pedal 1 without taking out the garbage inner barrel.

The scissor mechanism occupies a small part of the internal space at the top of the garbage can. After the pedal 1 is stepped down, a scissor mechanism in the garbage can is unfolded to compress garbage in the can.

The included angle between the in-box rack groove 11 at the top end in the garbage can and the horizontal plane is 20 degrees.

The two rods in each set of "X" shaped cross scissor rod sets are both 380mm long. The position where the two bars are crossed and connected is not at the center of the bars, but at the position 40mm to the right of the center, namely the ratio of the lengths of the left and right bars is 15: 23.

The position of the scissors link connected to the small link 27 is not at the center of the bar but at a position 10mm to the left of the center.

Advantageous effects

1) The whole compression process does not need to take out the garbage can, and a good protection effect can be achieved on a clean and sanitary dining environment of a fast food restaurant.

2) The user need step on the footboard with the foot after dumping rubbish and carry out the compression of rubbish, and this kind of mode is that the weight through the user provides the compressive force, and old and young is fit for.

Detailed Description

As shown in fig. 1 to 4, a garbage compressing apparatus suitable for use in fast food restaurants comprises a foot board 1, a left base 2, a right base 6, a garbage can door 3, a garbage inlet 4, a garbage can housing 5, a garbage inner barrel 7, a compression plate 8, a scissor mechanism, an in-can frame slot 11, an upper frame 13, an upper frame rotating rod 14, a long connecting rod 22, a lower frame 23 and a small connecting rod 27; the scissor mechanism comprises two first scissor rods 9, two second scissor rods 10, two third scissor rods 16, two fourth scissor rods 19, a first scissor connecting rod 15, a second scissor connecting rod 17, a third scissor connecting rod 18, a fourth scissor connecting rod 20, a fifth scissor connecting rod 21, a sixth scissor connecting rod 24, a seventh scissor connecting rod 25, an eighth scissor connecting rod 26 and a scissor connecting rod 12;

the overall shape of the garbage can with the garbage compressing device is shown in figure 1. The initial position of the compression means within the barrel is shown in figure 2. In use, a user would need to pour trash from the trash inlet 4 into the trash can and then step down on the end of the foot pedal 1. Since the foot board 1 is connected to the long link 22, the foot board rotates around the lower frame 23 while moving the long link 22 upward. The long link 22 is connected to the upper frame rotating rod 14, and the upper frame rotating rod 14 rotates around the upper frame 13 when the long link 22 moves upward. The upper frame rotating rod 13 is connected with the small connecting rod 27, when the left end of the upper frame rotating rod 14 moves downwards, the small connecting rod 27 is driven to move downwards, and the small connecting rod 27 is connected with the scissors rod 10 through the scissors connecting rod 12, so that the scissors rod 10 rotates around the scissors connecting rod 17. The scissor lever 10 is connected in the middle to the scissor lever 16 by means of a scissor link 15, because one end of the scissor lever 16 is attached to a slide groove in the frame slot 11 in the box by means of a scissor link 26 and can move freely in this groove. When the scissor rod 10 rotates around the scissor connecting rod 17 on the rack groove 11 in the garbage bin, the scissor rod 16 is driven to rotate, and meanwhile, the scissor rod 9 and the scissor rod 19 connected with the two scissor rods rotate, so that the whole scissor mechanism is unfolded, the compression plate 8 moves downwards in an arc-shaped track, and garbage in the garbage bin is compressed in the downward movement process. After the compression is completed, the treaded end of the pedal 1 is lifted, the process is reversed, and the compression plate 8 is finally lifted and returned to the initial position.

After the garbage can is full, a user can open the garbage can door 3, take out the garbage inner can 7 and dump garbage.
