[0034] The utility model is further described below in conjunction with specific embodiments:
[0035] like Figure 7-12 As shown, a trash can comprises a supporting barrel body 1 and an inner barrel body 2. The upper end of the supporting barrel body 1 extends inwardly along the garbage delivery port to form a circle of connecting edges 11. The connecting edges 11 are provided with a snap-on hole 12. The top of the inner barrel body 2 is provided with a snap-on 21 corresponding to the snap-on hole 12. The inner barrel body 2 can be installed on the snap-on hole 12 of the supporting barrel body 1 through the snap-on 21. In this technical solution, the supporting barrel body 1 is used to fix the trash can as a whole to the ground. The top of the supporting barrel body 1 is the garbage delivery port. The delivery port will extend inwardly with a circle of connecting edges 11 for fixing the garbage delivery port. The inner barrel body 2 is provided with corresponding snap-in holes 12 and snap buckles 21 therebetween. The snap buckles 21 are integrally formed at the top of the inner barrel body 2, which is more secure and stable. Gaps 22 are provided on both sides of the snap buckles 21, which are wider at the top and narrower at the bottom, so that the assembly is smoother. For the specific shapes and positions of the snap-in holes 12 and the snap buckles 21, please refer to the attached drawings in the specification. The snap buckles 21 of the inner barrel body 2 are inserted into the snap-in holes 12 from bottom to top. This connection method is very convenient and labor-saving whether it is production and assembly or consumer replacement of the inner barrel body 2.
[0036] Further, such as Figure 1-6As shown, the supporting barrel body 1 and the inner barrel body 2 of the trash can can be folded and stored using a retractable structure to reduce storage and transportation space. The retractable structure of the trash can can divide the supporting barrel body 1 and the inner barrel body into two upper and lower parts, including a first barrel body 3 and a second barrel body 4. The upper end of the first barrel body 3 extends outward to form a hanging edge 31, and the lower bottom of the second barrel body 4 is provided with a retractable opening 41. A clamping edge 42 and a limiting edge 43 are provided on the barrel body inside the retractable opening 41. A fixing groove 44 is formed between the clamping edge 42 and the limiting edge 43. When the first barrel body 3 is unfolded outward from the retractable opening 41 of the second barrel body 4, the hanging edge 31 can be After passing the clamping edge 42, it is blocked by the limiting edge 43 and restricted to be suspended in the fixing groove 44. In the present technical solution, the barrel body is divided into two parts, which can be telescopically folded up and down through the retractable opening 41. When unfolded, the hanging edge 31 can be fixed by the fixing groove 44 formed between the clamping edge 42 and the limiting edge 43. It is worth noting that the upper and lower relationship in the present technical solution is a relative concept. In order to facilitate the description of the adopted vocabulary, in fact, when the supporting barrel body 1 and the inner barrel body 2 are used, the directions may be opposite and they are adapted according to the actual situation. Moreover, after the first barrel body 3 and the second barrel body 4 in the present technical solution are combined, they can be used separately, which is more flexible.
[0037] Furthermore, a cover body 5 is hinged on the supporting barrel body 1, and a corresponding buckle 6 is provided at the upper end of the supporting barrel body 1. When the cover body 5 is closed, it can be buckled by the buckle 6. A groove 61 is formed at the upper end of the supporting barrel body 1, and the buckle 6 is arranged in the groove 61. In this technical solution, consumers can close the cover body 5 of the trash can by the buckle 6.
[0038] Furthermore, the barrel side walls of the first barrel body 3 and the second barrel body 4 tend to be inclined inward from top to bottom, and a circular chamfer 32 is formed on the lower bottom circumference of the first barrel body 3. In the present technical solution, the inclined barrel side walls are for facilitating the contraction and expansion between the barrel bodies, and the circular chamfer 32 can make the contact between the two smoother.
[0039] Furthermore, the limiting edge 43 is in a right-angle step shape, and its surface in contact with the hanging edge 31 is a horizontal plane, so that the limiting edge 43 has a stronger limiting effect on the hanging edge 31. The clamping edge 42 is in a semicircular shape, and its surface in contact with the hanging edge 31 of the first barrel 3 is an arc surface. The clamping edge 42 is in a triangular shape, and its surface in contact with the hanging edge 31 of the first barrel 3 is a straight inclined surface. Whether the clamping edge 42 is in a semicircular shape or a triangular shape can be selected according to actual conditions.
[0040] Furthermore, the number of the clamping edges 42 is more than two, so that the matching scheme between the first barrel body 3 and the second barrel body 4 is more diverse.
[0041] Furthermore, the clamping edge 42 is composed of several sections, each of which is separated by a gap. The specific shape of the structure can be found in the attached manual. Figure 4 And the instruction manual Fig.12 It can be applied to both the supporting barrel body 1 and the inner barrel body 2, which is not only convenient for installation and disassembly, but also conducive to demoulding. Regarding the shape of the snap-in edge 42, in order to facilitate snap-in, as an alternative, threads can be set at corresponding positions of the first barrel body 3 and the second barrel body 4 for connection.
[0042] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
