DETAILED DESCRIPTION

[0036] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1 to 14 A lifting trash can comprises an outer barrel 1 and an inner barrel 2 which is liftably arranged in the inner cavity thereof, a plurality of vertically arranged slots 3 are arranged on the inner wall of the outer barrel 1, and limiting plates 4 are respectively installed on both sides of the bottom of the inner barrel 2, a limiting portion 5 is formed at one end of the limiting plate 4, and a linkage mechanism 6 for controlling the movement of the limiting plate 4 is connected to the other end of the limiting plate 4, which is used to drive the limiting plate 4 to switch between a first state and a second state;

[0038] When the limiting plate 4 is in the first state, the limiting portion 5 is inserted into the slot 3, thereby limiting the relative movement between the outer barrel 1 and the inner barrel 2;

[0039] When the limiting plate 4 is in the second state, the limiting portion 5 leaves the slot 3, thereby allowing the inner barrel 2 to move upward or downward arbitrarily.

[0040] The present invention realizes that the inner barrel 2 can be raised and lowered and then stopped at any height for use, through the coordinated design of the limit plate 4 and the slot 3, so as to facilitate the collection of kitchen waste. In actual use, the limit plate can be driven by the linkage mechanism 6 to move to the side away from the slot 3. At this time, the inner barrel can move up or down, so as to freely adjust its height. When adjusted to the specified height, the limit plate can be driven by the linkage mechanism to move to the side close to the slot 3. At this time, the inner barrel is clamped on the inner periphery of the outer barrel by the limit plate, so as to fix the position of the inner barrel for subsequent use.

[0041] A bottom cover plate 7 is installed at the bottom of the inner barrel 2, and the linkage mechanism 6 is arranged between the bottom cover plate 7 and the bottom of the inner barrel 2. The structure is simple, so that the linkage mechanism 6 can be easily disassembled and assembled. An installation groove 8 for installing the limit plate 4 is formed between the two sides of the bottom cover plate 7 and the bottom of the inner barrel 2, so that the limit plate 4 can be kept moving in the installation groove 8.

[0042] In the present invention, the linkage mechanism 6 can adopt a variety of structural forms to drive the push-pull plate 9 to move forward and backward, and is not limited to the following structure in this embodiment: the linkage mechanism 6 includes a push-pull plate 9, and the two sides of the push-pull plate 9 are respectively formed with inclined slide grooves 10, and the other end of the limiting plate 4 is formed with an inclined slide bar 11 that cooperates with the inclined slide groove 10. The inclined slide bar 11 is movably arranged in the inclined slide groove 10. A button 12 is installed on the side wall of the inner barrel 2. The button 12 is connected to the push-pull plate 9 through a pull rope 13 to control the movement of the push-pull plate 9, thereby controlling the limiting plate 4 to switch between the first state and the second state.

[0043] The technical solution realizes the switching of the limit plate 4 between the first state and the second state through the design of the push-pull plate 9. In actual use, when the height of the inner barrel needs to be adjusted, the button 12 is first pressed, and the push-pull plate 9 will be driven to move through the pull rope 13. Through the cooperation of the inclined slide groove 10 and the inclined slide bar 11, the limit plate 4 can be driven to move to the side away from the slot 3 at the same time, that is, the limit plate 4 is in the second state at this time, and the limit part 5 leaves the slot 3, and the height of the inner barrel can be freely adjusted. The pull rope 13 can be made of elastic material, so that when the button is released, the push-pull plate 9 and the limit plate 4 can be pulled by the elastic force of the pull rope to achieve automatic reset, that is, when the limit plate 4 is in the first state at this time, the limit part 5 is stuck in the slot 3, thereby limiting the relative movement between the outer barrel 1 and the inner barrel 2.

[0044] The side wall of the push-pull plate 9 is formed with a spring mounting column 14, and a reset spring 15 is arranged on the periphery of the spring mounting column 14. The reset spring 15 abuts between the push-pull plate 9 and the bottom cover plate 7, thereby providing automatic reset force for the push-pull plate 9 and the limit plate 4. After releasing the button, the push-pull plate 9 and the limit plate 4 can be automatically reset by relying on the elastic force of the spring, so that the limit plate 4 automatically resets to the first state, and there is no need to manually control its movement, so the operation is simpler and more convenient.

[0045] A mounting cavity 16 for mounting the button 12 is formed on the side wall of the inner barrel 2, a fixing column 17 is arranged in the mounting cavity 16, a fixing hole 18 is opened in the button 12, one end of the fastener passes through the fixing hole 18 and is connected with the fixing column 17, a reset spring 2 19 is arranged on the outer periphery of the fixing column 17, the reset spring 2 19 abuts between the button 12 and the inner barrel 2, so as to further provide automatic reset force for the push-pull plate 9 and the limit plate 4, after releasing the button, the button can be automatically reset by the action of the spring, so that the push-pull plate 9 and the limit plate 4 are pulled by the pull rope to further realize automatic reset, and there is no need to manually control their movement, so the operation is simpler and more convenient.

[0046] The upper end surface of the limit plate 4 is formed with a straight slide groove 20, and the bottom of the inner barrel 2 is formed with a straight slide bar 21 that cooperates with the straight slide groove 20. The technical solution uses the coordinated design of the straight slide bar 21 and the straight slide groove 20 to enable the limit plate 4 to maintain a straight line forward and backward movement in the installation groove 8 during actual work, which helps to improve the stability of the structure.

[0047] The bottom cover plate 7 is provided with a roller 22 for the pull rope 13 to be wound around, which reduces friction and makes the operation more labor-saving. The outer periphery of the roller 22 is formed with a wire groove 23 to prevent the pull rope 13 from falling off the roller 22.

[0048] The ends of the bottom cover plate 7 are respectively formed with limiting protrusions 24, and the inner periphery of the upper port of the outer barrel 1 is formed with an inner flange 25 for the limiting protrusions 24 to abut against. When the inner barrel 2 moves to the uppermost end of the outer barrel 1, it can limit the movement of the inner barrel 2 and prevent the inner barrel 2 from falling off from the outer barrel 1.

[0049] Combination Figure 5 and Figure 6 The ends of the limiting portion 5 are respectively formed with an inclined surface 1 26 and abutting portion 1 27, and the slot 3 is respectively formed with an inclined surface 28 and abutting portion 29. The technical solution uses the design of the inclined surface to make it easier to adjust the height of the inner barrel without having to operate a button. In actual operation, when the inner barrel is pulled upward, the limiting plate 4 can slide on the inclined surface 28 through the inclined surface 1 26, and after the limiting plate 4 is automatically moved to the side away from the slot 3, the limiting portion 5 slides from the lower slot 3 to the upper slot 3 to achieve height adjustment. A spring is provided at the rear end of the limiting plate 4, so that the limiting plate 4 has the function of automatic resetting.

[0050] In this case, the linkage mechanism can use a pull rope to directly connect the limit plate to directly drive the limit plate to move, further simplifying the structure, such as Figure 15-16 As shown, the bottom cover plate 7 is divided into two left and right parts, which are respectively installed on both sides of the bottom of the inner barrel. The linkage mechanism 6 includes a button 12 installed on the side wall of the inner barrel 2. The button 12 is directly connected to the limit plate 4 through a pull rope 13 to control the limit plate 4 to switch between the first state and the second state. A plurality of rollers 22 are arranged at the bottom of the inner barrel for the pull rope 13 to be wound around, so that a horizontal force can be applied to the limit plate 4 after the button is pressed. A reset spring is arranged between the limit plate 4 and the bottom cover plate and the bottom of the inner barrel, so that the limit plate 4 has the function of automatic reset. The linkage mechanism can also adopt a conventional connecting rod mechanism to drive the limit plate to move, thereby improving the stability of the structure. Therefore, technicians in this field can adopt a variety of structural forms to drive the push-pull plate 9 to move forward and backward without creative labor.

[0051] Combination Fig.12 and Fig.13A through hole 30 is provided at the bottom of the inner barrel 2, and a damper plate 31 is rotatably provided in the through hole 30. A base 32 is installed at the bottom of the outer barrel 1, and a through hole 33 is provided in the base 32, and a damper plate 34 is rotatably provided in the through hole 33. A caster 35 is installed on the lower end surface of the base 32. Through the design of the damper plate, the technical solution allows the air between the garbage bag and the bottom of the barrel to be discharged through the damper plate during the laying of the garbage bag, so that the bottom of the garbage bag can be laid flat on the bottom of the barrel, thereby improving the utilization rate of the garbage bag.
