Description
Technical Field
[0001] This utility model relates to the field of sanitation equipment technology, specifically to a leak-proof sealing door structure for garbage transfer vehicles. Background Technology
[0002] With the acceleration of urbanization, garbage transfer vehicles are being used more and more frequently. During transportation, they are prone to sewage leakage due to inadequate sealing, causing secondary pollution. Traditional garbage transfer vehicle doors mostly use a rigid closing structure, which is prone to deterioration in sealing performance due to wear or deformation after long-term use, and lacks self-compensation capabilities, making it difficult to effectively cope with frequent opening and closing and vibration conditions. Existing sealing technologies mostly rely on fixed sealing strips, which cannot maintain continuous compression when the sealing strips age or the door shifts, affecting the sealing effect. Utility Model Content
[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed and easy-to-use anti-leakage sealing door structure for garbage transfer vehicles, which can effectively solve the defects of the existing technology.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes an installation frame, sealing doors, and rotating shafts. The installation frame is fixed to the garbage truck body. Sealing doors are symmetrically arranged on the left and right sides inside the installation frame. Rotating shafts are inserted through and fixed into each sealing door on the side adjacent to the side wall of the installation frame. The rotating shafts are screwed onto the upper and lower side walls of the installation frame via bearings. It also includes: The opening and closing mechanism consists of two mechanisms, which are respectively located in the upper and lower side walls of the mounting frame. The opening and closing mechanism is connected to the sealing door, and the upper and lower sides of the sealing door are embedded in and abut against the grooves on the mounting frame. The first sealing strip consists of two strips, which are symmetrically embedded in the two side walls of the mounting frame. The first sealing strip is designed to cooperate with and abut against the sealing door. Each first sealing strip is fixed with a mounting plate, which is movably set in the two side walls of the mounting frame. Push springs, there are several push springs, and they are equally and equidistantly embedded in the mounting plates on both sides. The other end of the push spring passes through the mounting plate and is fixed to the inner wall of the side of the mounting frame. Through the above technical solution, the sealing door can be opened and closed by the opening and closing mechanism. After the sealing door is closed, the No. 1 sealing strip abuts against the sealing door, which increases the sealing performance between the sealing door and the mounting frame. When the sealing door is opened, under the action of the pushing spring, the mounting plate drives the No. 1 sealing strip to move outward, so that the No. 1 sealing strip remains in contact with the sealing door, thereby improving the sealing performance between the sealing door and the mounting frame.
[0005] As a further improvement of this utility model, limit strips are fixed on both the left and right side walls of the inner side of the mounting plate, and the limit strips are slidably arranged in the sliding grooves inside the two sides of the mounting frame. The above technical solution can prevent the mounting plate from being removed from the mounting frame.
[0006] As a further improvement of this utility model, the opening and closing mechanism includes: The mounting blocks are two in number, and they are respectively fixed on one side of the sealing door adjacent to the side wall of the mounting frame. Each mounting block is screwed with a connecting rod No. 1 through a shaft. A connecting seat, one end of which is screwed to the other end of a first connecting rod via a shaft, and the other end of which is screwed into the side wall of the mounting frame via a shaft; The drive mechanism is located inside the side wall of the mounting frame and is connected to the connecting seat. Using the above technical solution, the drive mechanism is activated, which drives the connecting seat to rotate around the shaft that is screwed to the mounting frame. The connecting seat drives the first connecting rod to move, and the first connecting rod drives the sealing door to rotate around the rotating shaft through the mounting block.
[0007] As a further improvement of this utility model, the driving mechanism includes: The drive plate is triangular in shape. The center of the drive plate is screwed into the side wall of the mounting frame via a shaft. Two support rods are screwed into both sides of the drive plate via shafts. The other end of each support rod is screwed into the other end of the connecting seat via a shaft. A connecting ring is sleeved on a protrusion on the side wall of the drive plate. One side of the outer ring wall of the connecting ring is connected to an electric push rod through a hinge plate. The fixed end of the electric push rod is connected to the inner wall of the mounting frame through a hinge seat. Using the above technical solution, the electric push rod is activated, and the electric push rod drives the drive plate to rotate around its central shaft via the connecting ring. The two sides of the drive plate then drive the second support rod to move, and the second support rod drives the connecting seat to rotate.
[0008] As a further improvement of this utility model, the sealing door is inclined on the side away from the rotating shaft, and a second sealing strip is embedded on the inclined surface of the sealing door, with the second sealing strips on both sides cooperating and abutting each other. Through the above technical solution, the inclined sidewall of the sealed door makes the joint between the two doors inclined, which can initially prevent leakage. At the same time, the second sealing strip between the two sealed doors can further prevent leakage and improve the sealing performance of the sealed door.
[0009] As a further improvement of this utility model, an abutment strip is provided on the lower side inside the mounting frame. The lower side of the abutment strip is embedded in the embedding groove on the bottom wall of the mounting frame. A rotating rod is inserted through the abutment strip. The rotating rod is connected to the mounting frame through a torsion spring. The abutment strip cooperates with the sealing door to abut. With the above technical solution, when the sealed door is closed, the contact strip abuts against the sealed door, thereby blocking the garbage to a certain extent. When the sealed door is opened, the contact strip rotates outward under the elastic force of the torsion spring, thereby guiding the garbage.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The anti-leakage sealing door structure for garbage transfer vehicles described in this utility model significantly improves the anti-leakage performance and service life of the sealing door through elastic sealing and automatic compensation structure. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:
[0018] like Figures 1-5As shown, this embodiment includes an installation frame 1, a sealing door 2, and a rotating shaft 3. The installation frame 1 is welded and fixed to the garbage truck body. The installation frame 1 has symmetrically arranged sealing doors 2 inside. A rotating shaft 3 is inserted and fixed into each sealing door 2 on the side adjacent to the side wall of the installation frame 1. The rotating shaft 3 is screwed onto the upper and lower side walls of the installation frame 1 via bearings. It also includes: The opening and closing mechanism 4 consists of two parts, which are respectively installed in the upper and lower side walls of the mounting frame 1. The opening and closing mechanism 4 is connected to the sealing door 2. The upper and lower sides of the sealing door 2 are embedded in and abut against the grooves on the mounting frame 1. The side of the sealing door 2 away from the rotating shaft 3 is inclined. A second sealing strip 9 is embedded in the inclined surface of the sealing door 2. The second sealing strips 9 on both sides are engaged and abut against each other. The inclined side walls of the sealing door 2 make the joint between the two doors inclined, which can initially prevent leakage. At the same time, the second sealing strip 9 between the two sealing doors 2 can further prevent leakage and improve the sealing performance of the sealing door 2. An abutment strip 10 is provided on the lower side inside the mounting frame 1. The lower side of the abutment strip 10 is embedded in the groove on the bottom wall of the mounting frame 1. A rotating rod 11 is inserted through the abutment strip 10. The rotating rod 11 is connected to the mounting frame 1 through a torsion spring. The abutment strip 10 cooperates with the sealing door 2 to abut. When the sealing door 2 is closed, the abutment strip 10 abuts against the sealing door 2, thereby blocking the garbage to a certain extent. When the sealing door 2 is opened, the abutment strip 10 rotates outward under the elastic force of the torsion spring, thereby guiding the garbage. Two sealing strips 5 are symmetrically embedded and adhered to the two side walls of the mounting frame 1. The sealing strips 5 are designed to abut against the sealing door 2. Mounting plates 6 are adhered and fixed to each sealing strip 5. The mounting plates 6 are movably mounted inside the two side walls of the mounting frame 1. Limiting strips 8 are welded and fixed to the left and right side walls of the inner side of the mounting plate 6. The limiting strips 8 are slidably mounted in the sliding grooves inside the two sides of the mounting frame 1 to prevent the mounting plate 6 from moving out of the mounting frame 1. A number of push springs 7 are installed in equal quantities and at equal intervals in the mounting plates 6 on both sides. The front end of the push spring 7 passes through the mounting plate 6 and is fixed to the inner wall of the side of the mounting frame 1. Example 2:
[0019] See Figure 2-4 As shown, based on Embodiment 1, the opening and closing mechanism 4 includes: Mounting block 4-1, there are two mounting blocks 4-1, and they are respectively fixed on one side of the sealing door 2 adjacent to the side wall of the mounting frame 1. Each mounting block 4-1 is screwed with a connecting rod 4-2 through a shaft. Connecting seat 4-3, one end of which is screwed to the other end of connecting rod 4-2 via a shaft, and the other end of connecting seat 4-3 is screwed into the side wall of mounting frame 1 via a shaft; Drive mechanism 4-4 is disposed within the side wall of mounting frame 1 and is connected to connecting seat 4-3; drive mechanism 4-4 includes: The drive plate 4-4-1 is triangular in shape. The center of the drive plate 4-4-1 is screwed into the side wall of the mounting frame 1 via a shaft. The two side walls of the drive plate 4-4-1 are each screwed with a second support rod 4-4-2 via a shaft. The other end of the second support rod 4-4-2 is screwed into the other end of the connecting seat 4-3 via a shaft. The connecting ring 4-4-3 is sleeved on the protrusion on the side wall of the drive plate 4-4-1. One side of the outer ring wall of the connecting ring 4-4-3 is connected to the electric push rod 4-4-4 through a hinge plate. The fixed end of the electric push rod 4-4-4 is connected to the inner wall of the mounting frame 1 through a hinge seat.
[0020] When using this utility model, the electric push rod 4-4-4 is activated. The electric push rod 4-4-4 drives the drive plate 4-4-1 to rotate around its central shaft via the connecting ring 4-4-3. The two sides of the drive plate 4-4-1 then drive the second support rod 4-4-2 to move. The second support rod 4-4-2 drives the connecting seat 4-3 to rotate around its shaft that is screwed to the mounting frame 1. The connecting seat 4-3 drives the first connecting rod 4-2 to move. The first connecting rod 4-2 drives the sealing door 2 to rotate around the rotating shaft 3 via the mounting block 4-1. After the sealing door 2 is closed, the first sealing strip 5 abuts against the sealing door 2, increasing the sealing between the sealing door 2 and the mounting frame 1. When the sealing door 2 is opened, under the action of the push spring 7, the mounting plate 6 drives the first sealing strip 5 to move outward, so that the first sealing strip 5 remains in contact with the sealing door 2, improving the sealing between the sealing door 2 and the mounting frame 1.
[0021] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. By continuously applying pressure to the first sealing strip 5 by pushing the spring 7, it is kept in close contact with the sealing door 2. This automatic compensation mechanism can adapt to wear and deformation, improving the reliability of leakage prevention during long-term use; 2. The linkage mechanism combining the connecting rod and the triangular drive plate 4-4-1 is adopted. The two sealing doors 2 can be driven synchronously by one electric push rod 4-4-4, which realizes the smoothness, smoothness and synchronization of the opening and closing process and ensures the accuracy of the action. 3. An inclined contact surface is used at the joint of the two sealed doors 2 and a second sealing strip 9 is installed. Combined with the first sealing strip 5 on the side, multiple sealing barriers are formed, which greatly enhances the overall sealing effect against sewage and odor. 4. The bottom contact strip 10 blocks garbage when the door is closed and automatically flips under the action of the torsion spring when the door is opened. This not only prevents garbage from overflowing and getting stuck, but also guides the unloading process, making it highly practical.
[0022] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
