Description

Technical Field

[0001] The utility model belongs to the field of mobile garbage bins, in particular to a double-locking garbage bin with unequally spaced frames. Background Art

[0002] The mobile trash bins in the prior art have the following disadvantages: 1. The side frames of the mobile trash bins are arranged at equal distances, but in the actual process of compressing garbage, the rear part of the bin is subjected to great force, which causes the rear side panels of the bin to be easily deformed and the welds to crack, resulting in water leakage; 2. The lock hook of the rear door of the mobile trash bin is arranged downward, and the rear door is completely locked by the force of the cylinder. If the cylinder fails, the rear door will slide downward and open under gravity, and the garbage will fall during transportation; 3. The water storage space at the bottom of the bin is open. Since the garbage enters the bin from the rear door, the bottom gap will be blocked by the garbage, and the water below cannot be discharged normally. Utility Model Content

[0003] The utility model aims to provide a double-locking trash bin with unequally spaced frames, which improves the locking reliability of the rear door by arranging the rear door lock hook upwards and adopting a hydraulic and mechanical double locking structure.

[0004] The purpose of the present utility model is achieved as follows: a double-locking trash can with unequally spaced frames, comprising a box body, an opening provided at the rear of the box body, a rear door provided corresponding to the opening, at least one upwardly extending lock hook provided on the left and right sides of the rear end of the box body, a lock slot of the lock hook being located on the upper side of the lock hook body, a lock pin provided on the left and right sides of the rear door corresponding to each lock hook, the lock pin fittingly snapping into the lock slot of the corresponding lock hook, the rear door being rotatably connected to a lifting support on the box body, and the lifting support being transmission-connected to a lifting drive mechanism.

[0005] The rear door lock hook of this utility model adopts an inverted structure, providing both hydraulic and mechanical locking. With the lock hook and mechanical locking pin engaged, even if the hydraulic cylinder fails, the rear door will not open. To open the rear door, the hydraulic cylinder first drives the lifting support and rear door upward. After the rear door lock pin disengages from the bin lock hook, the rear door drive cylinder mounted on the bin body pushes the rear door upward, opening it. Compared to the existing technology, the utility model has the beneficial effect of improving the reliability of rear door locking by arranging the rear door lock hook upward and adopting a dual hydraulic and mechanical locking structure.

[0006] As a further improvement of the present invention, the locking pin is a round pin, and the locking hook is vertically inserted into the locking groove of the corresponding locking hook.

[0007] As a further improvement of the present invention, the lifting supports are symmetrically provided with two, and the upper portion of the rear door is provided with two symmetrical connecting plates, which are respectively hinged to the two lifting supports. The connecting plates of the rear door are flipped upward relative to the lifting supports to open the rear door.

[0008] As a further improvement to the present invention, the lifting drive mechanism comprises two drive assemblies, one on each side of the rear of the box. These drive assemblies include two guide sleeves, each movably connected to a lifting column. Two lifting supports are fixed to the upper ends of the two lifting columns, each with a hinged seat on its side. A hydraulic cylinder is hingedly connected to each lifting column on the box via a fixed seat, and the working end of the hydraulic cylinder is hingedly connected to the corresponding hinged seat. The hydraulic cylinder drives the lifting column upward, pushing the lifting support and the rear door upward as a whole, disengaging the rear door lock pin from the box lock hook.

[0009] As a further improvement to the present invention, the box includes a plurality of frames spaced apart along its length. Four rectangular side panels are positioned between any two adjacent frames, with the spacing between adjacent frames decreasing from the front to the rear of the box. The unequal spacing of the frames allows the rear frame, which bears greater stress, to be closer together, resulting in better stress absorption and structural strength.

[0010] As a further improvement to the present invention, a pallet is provided inside the box, with a garbage storage space and a sewage storage space formed above and below the pallet, respectively. The pallet is covered with multiple drainage holes and is a porous plate. A shielding door corresponding to the sewage storage space is rotatably connected to the rear side of the pallet. The bottom sewage storage space has a reversible shielding door. When the garbage is compressed and enters the box, the shielding door is closed to prevent the garbage from entering the water storage space and causing blockage. When the garbage bin is lifted and unloaded, the front of the box is lifted upward, and the shielding door flips open with gravity, allowing the sewage in the bottom sewage storage space to flow out smoothly.

DETAILED DESCRIPTION

[0020] like Figure 1-8 As shown, a double-locking trash can with unequally spaced frames includes a box body 1, an opening is provided at the rear of the box body 1, and a rear door 2 is provided corresponding to the opening. At least one upwardly extending lock hook 3 is provided on the left and right sides of the rear end of the box body 1, and a lock slot 3a of the lock hook 3 is located on the upper side of the lock hook 3 body. A lock pin 4 is provided on the left and right sides of the rear door 2 corresponding to each lock hook 3, and the lock pin 4 is fitted into the lock slot 3a of the corresponding lock hook 3. The lock pin 4 is a round pin, and the lock hook 3 is vertically inserted into the lock slot 3a of the corresponding lock hook 3; the rear door 2 is rotatably connected to the lifting support 5 on the box body 1, and the lifting support 5 is transmission-connected to the lifting drive mechanism.

[0021] Two lifting supports 5 are symmetrically arranged on the left and right sides. Two symmetrical connecting plates 6 are provided on the upper portion of the rear door 2. The two connecting plates 6 are hinged to the two lifting supports 5, respectively. The connecting plates 6 of the rear door 2 flip upward relative to the lifting supports 5, opening the rear door 2. The lifting drive mechanism includes two drive assemblies, respectively arranged on the left and right sides of the rear portion of the housing 1. The drive assemblies include two guide sleeves 7, each of which is movably connected to a lifting column 8. The two lifting supports 5 are respectively fixed to the upper ends of the two lifting columns 8. The sides of the lifting columns 8 are provided with hinged seats 9. A hydraulic cylinder 10 is hingedly connected to each lifting column 8 on the housing 1 via a fixed seat 11. The working end of the hydraulic cylinder 10 is hinged to the corresponding hinged seat 9. The hydraulic cylinder 10 drives the lifting columns 8 upward, pushing the lifting support 5 and the rear door 2 upward as a whole, causing the rear door 2 lock pin 4 to separate from the housing 1 lock hook 3.

[0022] The box 1 includes several frames 1a spaced apart along its length. Four rectangular side panels 1b are positioned between any two adjacent frames 1a. The spacing between adjacent frames 1a decreases from the front to the rear of the box 1. The frames 1a are arranged at unequal intervals, so the rear frame 1a, which bears greater stress, is closer together, providing better stress resistance and structural strength.

[0023] A support plate 12 is provided inside the box body 1. A garbage storage space 1313 and a sewage storage space 14 are formed above and below the support plate 12, respectively. The support plate 12 is covered with multiple drainage holes and is a porous plate. A shielding door 12a corresponding to the sewage storage space 14 is rotatably connected to the rear side of the support plate 12. The bottom sewage storage space 14 has a reversible shielding door 12a. When the garbage is compressed and enters the box body 1, the shielding door 12a is closed to prevent the garbage from entering the water storage space and causing blockage. When the garbage bin is lifted to unload, the front of the box body 1 is lifted upward, and the shielding door 12a flips open due to gravity, allowing the sewage in the bottom sewage storage space 14 to flow out smoothly.

[0024] The locking hook 3 of the rear door 2 of the present invention adopts an inverted structure, providing both hydraulic and mechanical locking. With the locking hook 3 and the locking pin 4 mechanically locked, even if the hydraulic cylinder 10 fails, there is no risk of the rear door 2 opening. To open the rear door 2, the hydraulic cylinder 10 first drives the lifting support 5 and the rear door 2 upward. After the locking pin 4 of the rear door 2 separates from the locking hook 3 of the bin body 1, the rear door 2 drive cylinder mounted on the bin body 1 pushes the rear door 2 upward, thereby opening the rear door 2. The advantages of the present invention are that by arranging the locking hook 3 of the rear door 2 upward and adopting a dual hydraulic and mechanical locking structure, the locking reliability of the rear door 2 is improved.

[0025] The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solutions disclosed in the present invention, technicians in this field can make some substitutions and deformations of some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
