DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 10As shown, a pedal-operated openable and closeable trash can that is easy to clean includes an outer barrel 11, an inner barrel 15, a barrel cover 12 and a pedal 21. The inner barrel 15 is movably placed in the outer barrel 11, and the barrel cover 12 is hinged on the outer barrel 11. Preferably, the barrel cover 12 is hinged on the outer barrel 11 through a hinge 13, and the pedal 21 is movably installed on the lower part of the outer barrel 11 through a rotating shaft 20. A connecting rod assembly for controlling the swing of the barrel cover 12 and controlling the lifting of the inner barrel 15 is connected between the pedal 21 and the barrel cover 12. A fixed barrel 17 is fixed in the outer barrel 11. The fixed barrel 17 has a placement cavity 112 with an opening upward, and the inner barrel 15 is movably arranged in the placement cavity 112. The upper end of the fixed barrel 17 is provided with an abutment ring 171. In this embodiment, the abutment ring 171 is arranged above the placement cavity 112, and the aperture of the abutment ring 171 is larger than the outer diameter of the barrel body of the inner barrel 15. The upper end of the inner barrel 15 is provided with an annular block 151 that cooperates with the abutment ring 171. The outer diameter of the annular block 151 is larger than the aperture of the abutment ring 171. When the inner barrel 15 is placed in the outer barrel 11, the lower end of the annular block 151 abuts against the abutment ring 171. The upper end of the ring 171 is abutted and matched, and a plurality of evenly distributed mounting holes 152 are provided on the annular block 151. A clamping hole 172 corresponding to the mounting hole 152 is provided on the abutting ring 171. In this embodiment, the number of mounting holes 152 and clamping holes 172 is six. A pressing block 3 connected with the clamping hole 172 is installed in each mounting hole 152. A spring 33 is abutted between the pressing block 3 and the mounting hole 152. The spring 33 always has a tendency to push the inner barrel 15 to move upward. The lower end of the pressing block 3 corresponds to the shape of the clamping hole 172. When the garbage bag is put on the inner barrel 15, the garbage bag is folded to the bottom of the annular block 151 and the pressing block 3. At this time, when the inner barrel 15 is placed in the placement cavity 112, after the inner barrel 15 falls, the annular block 151 and the abutment ring 171 abut and cooperate, and the lower end of the pressing block 3 falls into the clamping hole 172, so that the garbage bag is clamped between the pressing block 3 and the clamping hole 172, thereby achieving the function of fixing the garbage bag, preventing the garbage bag from falling off due to heavy garbage thrown into the garbage bag, and making the garbage bag more stable and not falling when it is put on the inner barrel 15.

[0029] Furthermore, the pressure block 3 includes a fixing rod 31 and a clamping block 32. The fixing rod 31 is movably installed in the mounting hole 152. The clamping block 32 is clamped and fitted at the lower end of the fixing rod 31. The spring 33 abuts between the fixing rod 31 and the mounting hole 152. The clamping block 32 is made of rubber. The clamping block 32 cooperates with the hole, and the clamping block 32 is made of rubber, which can further increase the friction force, thereby further enhancing the stability of the garbage bag set outside the inner barrel 15. The clamping hole 172 and the clamping block 32 are truncated cone-shaped, so the clamping block 32 can better enter the clamping hole 172. In addition, preferably, a rubber pad can be provided on the inner wall of the clamping hole 172 to further increase the friction force.

[0030] A lower chamber 111 is provided at the lower side of the outer barrel 11, and the rotating shaft 20 is installed in the lower chamber 111. The outer barrel 11 is provided with an open groove 14, and the pedal 21 is swingably arranged in the groove 14. The groove 14 opens toward a side away from the axis of the outer barrel 11, and the pedal 21 extends into the lower chamber 111. The connecting rod assembly includes a swing plate 210, which is connected to one end of the pedal 21 located in the lower chamber 111. The swing plate 210 is rotatably arranged on the outer periphery of the rotating shaft 20. The outer barrel 11 is also provided with a push rod chamber 113 connected to the lower chamber 111, and the swing plate 210 extends to the push rod. In the cavity 113, a swing plate 210 is located at one end of the push rod cavity 113 and is movably connected to a push rod 22. The top of the push rod 22 abuts against the lower end of the barrel cover 12. A guide block 18 is provided in the push rod cavity 113. The push rod 22 is movably arranged in the guide block 18. The barrel cover 12 is driven to swing by the lifting and lowering of the push rod 22. A top barrel assembly abuts against the bottom of the inner barrel 15 is provided in the middle of the swing plate 210. The top barrel assembly and the pedal 21 are located on both sides of the rotating shaft 20. Therefore, by stepping on the pedal 21 to make it swing, the top barrel assembly moves upward, thereby pushing the inner barrel 15 to rise.

[0031] A mating cavity 212 is provided in the swing plate 210, and a first movable block 221 movably arranged in the mating cavity 212 is provided at the bottom of the push rod 22. A contact block 121 that abuts against the push rod 22 is provided at the lower end of the barrel cover 12, and an arc groove 122 is provided on the contact block 121. The upper end of the push rod 22 also has an arc portion that cooperates with the arc groove 122.

[0032] The top barrel assembly includes a connecting seat 24 installed on the swing plate 210, and a movable cavity 241 is provided in the connecting seat 24. A second movable block 231 is movably provided in the movable cavity 241. A connecting rod 23 is provided at the upper end of the second movable block 231. A push plate 16 abutting against the bottom of the inner barrel 15 is installed at the upper end of the connecting rod 23. The push plate 16 abuts against the center position of the bottom of the inner cylinder, so that the inner barrel 15 can be better pushed up.

[0033] The bottom of the matching cavity 212 and the movable cavity 241 both have an arc surface with a low middle and high ends, so that when the swing plate 210 swings, the first movable block 221 and the second movable block 231 will move to both ends, so that the first movable block 221 and the second movable block 231 can move upward when the swing plate 21 is driven to swing by stepping on the pedal 21.

[0034] A return spring 211 is disposed between the lower end of the pedal 21 and the bottom of the groove 14 . The return spring 211 is used for returning the pedal 21 .

[0035] When in use: step on the pedal 21, thereby driving the pedal 21 and the swing plate 210 to rotate around the rotating shaft 20, thereby driving the connecting seat 24 to move around the rotating shaft 20. When the swing plate 210 swings, the first movable block 221 moves in the matching cavity 212 and the second movable block 231 moves in the movable cavity 241. At the same time, the first movable block 221 and the second movable block 231 move upward at the same time, thereby driving the push rod 22 to move upward, and the arc-shaped portion at the top of the push rod 22 moves relative to the arc groove 122 in the abutment block 121, thereby pushing the bucket cover 12 to swing around the hinge 13, so that the bucket cover 12 swings upward to realize the opening of the trash can, and the second movable block 231 moves upward. At the same time as the movement, the connecting rod 23 and the push plate 16 are driven upward, thereby pushing up the inner barrel 15. At this time, the fixing rod 31 uses the force of the spring 33 to keep the clamping block 32 in the clamping hole 172 at all times. If the garbage bag needs to be removed, the inner barrel 15 is manually lifted to disengage the clamping block 32 from the clamping hole 172. Therefore, the garbage bag can be easily removed from the inner barrel 15 at this time, making it easier to clean. In addition, the garbage bag is more stable by being clamped between the clamping block 32 and the clamping hole 172, and the garbage bag will not fall into the inner barrel 15 completely. Therefore, there will be no situation where garbage is thrown into the inner barrel 15, and there will be no situation where garbage falls into the inner barrel 15 and the inner barrel 15 needs to be cleaned.

[0036] When the inner barrel 15 is placed in the placement cavity 112, the block 32 and the hole 172 are always matched. Only when the inner barrel 15 is manually lifted will the block 32 and the hole 172 be disengaged. The inner barrel 15 moves up and down along the axis of the fixing rod 31. As more and more garbage is in the inner barrel 15, the gravity of the inner barrel 15 continues to increase, and the inner barrel 15 will move downward. At the same time, the spring 33 is stretched to store elastic potential energy.

[0037] When the pedal 21 is pressed to lift the inner barrel 15, the inner barrel 15 moves upward along the axis of the fixing rod 31, and the clamping block 32 and the clamping hole 172 are always matched with each other. Therefore, when the pedal 21 is pressed, the garbage bag is also clamped between the clamping block 32 and the clamping hole 17, and the garbage bag will not fall into the inner barrel 15.
