Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, and in particular to a small garbage collection vehicle. Background Technology

[0002] Small garbage collection vehicles are equipped by sanitation workers for convenient garbage collection in narrow areas such as roadsides or parks. Their main structure, as shown in the sanitation worker garbage truck disclosed in announcement number "CN217515905U", includes a frame and a bucket. The garbage bucket is fixedly installed on the bucket frame. By removing the bucket cover and driving the bucket frame backward, the garbage collected in the bucket can be dumped to a designated location. For example... Figure 5 , Figure 6 and Figure 7 As shown, the garbage bin is fixed to the frame using screws. Specifically, screw holes are drilled on both the garbage bin and the frame, and the fixing screws pass through the screw holes from the inside of the garbage bin and are screwed onto the fixing nuts on the outside. This exposes the screw heads to the inside of the garbage bin, where they are subjected to long-term corrosion from moisture, acidic substances, and salt in the garbage. The screw heads gradually decay until they lose their fixing function. However, by the time decay is detected, it is difficult to use tools to remove and replace the screw heads. Repairs can only be carried out when all the screws have decayed to the point where the garbage bin can be removed. However, because the decay rate of each screw is inconsistent, workers' subjective judgment of the decay level is inaccurate, making it difficult to determine the precise time for disassembly and repair. During this period, the garbage bin will be in a state where only some screws still provide fixation for an extended period, making it difficult to guarantee the stability of the garbage bin and leading to accidents such as tipping over and damage to structural components during travel on bumpy roads and garbage dumping. Therefore, measures need to be taken to prevent screw decay. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a small garbage collection vehicle that significantly reduces screw corrosion and facilitates long-term reliable fixing of the garbage bin.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a small garbage collection vehicle, including a frame, on which a garbage bin is installed, and a plurality of screw fixing devices are provided between the garbage bin and the frame; the screw fixing devices include screw mounting holes correspondingly provided on the garbage bin and the frame, fixing screws are inserted through the screw mounting holes, the head of the fixing screw is located inside the garbage bin, the outer end of the fixing screw is connected to a fixing nut, a protective base plate is sleeved on the fixing screw between the head and the inner wall of the garbage bin, a protective connecting ring is integrally provided around the periphery of the protective base plate, and a protective cover covering the head is threadedly installed on the protective connecting ring.

[0005] As a preferred technical solution, the protective cover is provided with a disassembly and assembly operation part.

[0006] As a preferred technical solution, the disassembly and assembly operation part includes polygonal protrusions and / or disassembly and assembly grooves provided on the outer surface of the protective cover.

[0007] As a preferred technical solution, a washer is fitted onto the fixing screw between the head and the protective base plate.

[0010] By adopting the above technical solution, a small garbage collection vehicle includes a frame, on which a garbage bin is mounted. Several screw fixing devices are provided between the garbage bin and the frame. Each screw fixing device includes corresponding screw mounting holes on the garbage bin and the frame. Fixing screws are inserted through these mounting holes, with the heads of the screws located inside the garbage bin. A fixing nut is connected to the outer end of the screw. A protective base plate is fitted onto the screw between the head and the inner wall of the garbage bin. A protective connecting ring is integrally formed around the head on the protective base plate, and a protective cap is threaded onto the protective connecting ring and placed over the head. This invention adds the protective base plate as the foundation for the protective connecting ring. After installing the protective cap, the head of the fixing screw is completely surrounded, making it difficult for sewage to contact the screw, thus significantly reducing screw corrosion and facilitating long-term reliable fixing of the garbage bin.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figure 1 and Figure 4 As shown, a small garbage collection vehicle includes a frame 1, on which a garbage bin 2 is mounted. Several screw fixing devices 3 are provided between the garbage bin 2 and the frame 1. Alternatively, when a tilting bin frame 11 is mounted on the frame 1, the garbage bin 2 is mounted on the bin frame 11, and in this case, the screw fixing devices 3 are provided between the garbage bin 2 and the bin frame 11.

[0022] Normally, such as Figure 2 As shown, the screw fixing device 3 includes screw mounting holes 31 correspondingly provided on the garbage bin 2 and the vehicle frame 1. A fixing screw 32 is inserted through the screw mounting hole 31. The head 33 of the fixing screw 32 is located inside the garbage bin 2, and a fixing nut 34 is connected to the outer end of the fixing screw 32. The fixing screw 32 is pushed out of the screw mounting hole 31 from inside the garbage bin 2, and the fixing nut 34 is installed on the outer end of the fixing screw 32. Then, the fixing screw 32 is rotated further, so that the head 33 and the fixing nut 34 clamp the wall of the garbage bin 2 and the vehicle frame 1, thereby achieving the purpose of fixing the garbage bin 2 on the vehicle frame 1.

[0023] In this embodiment, a protective base plate 4 is fitted onto the fixing screw 32, located between the head 33 and the inner wall of the garbage bin 2. A protective connecting ring 41 is integrally formed around the head 33, and a protective cover 5 is threaded onto the protective connecting ring 41 and placed over the head 33. When the protective base plate 4 is fitted and the fixing screw 32 is tightened, the head 33 and the fixing nut 34 can clamp the protective base plate 4 together, achieving the purpose of fixing the protective base plate 4, and ensuring a tight, seamless connection between the protective base plate 4 and the inner wall of the garbage bin 2. Then, the protective cover 5 is installed on the protective connecting ring 41. The head 33 is completely surrounded by the protective base plate 4, the protective connecting ring 41, and the protective cover 5, making it difficult for sewage to come into contact with the fixing screw 32, thus significantly reducing screw corrosion and facilitating long-term reliable fixing of the garbage bin 2. When disassembly is required, the protective cover 5 is removed first, and then the fixing screw 32 can be disassembled normally.

[0024] Preferably, such as Figure 2 and Figure 3 As shown, the protective cover 5 is provided with a disassembly and assembly operation part 51 to facilitate the disassembly and assembly of the protective cover 5. In this embodiment, the disassembly and assembly operation part 51 includes a polygonal protrusion and / or a disassembly and assembly groove provided on the outer surface of the protective cover 5. The polygonal protrusion, such as the hexagonal protrusion shown in the attached figure, allows for easy tightening with pliers or a wrench, while the disassembly and assembly groove, such as the elongated groove shown in the attached figure, allows for easy tightening with a knife-like tool. One or both can be provided as needed, and no limitation is made here.

[0025] Preferably, the protective substrate 4 and the protective cover 5 are made of plastic. Plastic has good chemical stability and is resistant to water, acidic components, salt, and other corrosive substances, thus providing long-term protection against corrosion of the fixing screw 32. Therefore, the protective substrate 4 and the protective connecting ring 41 can be integrally injection molded, and the protective cover 5 and the disassembly / assembly operation part 51 can also be integrally injection molded.

[0026] Preferably, such as Figure 1 and Figure 2 As shown, a washer 35 is fitted on the fixing screw 32 between the head 33 and the protective base plate 4. Through the washer 35, the head 33 of the fixing screw 32 can form a larger clamping area on the protective base plate 4, further promoting a tight and seamless connection between the protective base plate 4 and the inner wall of the garbage bin 2, reducing sewage erosion.

[0027] Preferably, such as Figure 2 and Figure 3As shown, the outer peripheral surface of the protective connecting ring 41 is a conical surface with a reduced diameter along the direction away from the inner wall of the garbage bin 2. In this way, the protective connecting ring 41 and the protective cover 5 can form a relatively smooth surface on the outside, with less hooking phenomenon, reducing obstruction to the garbage in the bin, and facilitating the normal operation of garbage dumping.

[0028] This embodiment adds the protective base plate 4, the protective connecting ring 41, and the protective cover 5 to the existing screw fixing device 3. With the fastening effect of the fixing screw 32, a comprehensive protective structure is formed around the head 33 of the fixing screw 32, effectively preventing sewage erosion. Adding the protective base plate 4, the protective connecting ring 41, and the protective cover 5 does not require changing the existing garbage bin 2 structure; that is, there is no need to redesign and reproduce the garbage bin 2 for the added structure. This embodiment can be directly used to replace the existing garbage bin 2, making it convenient to implement.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
