Description

Technical Field

[0001] This utility model relates to the field of tank truck cover technology, and in particular to a tank truck filling port cover structure. Background Technology

[0002] Tank trucks are specialized vehicles for transporting chemicals. Currently, the process vehicle fleet uses tank trucks specifically to transport fly ash and alumina to the electrolysis and Chinese eutectoid workshops. The vehicles have sealed feed covers to prevent particulate matter from becoming airborne. Existing standard tank truck feed covers are secured with six screws. While this secures the cover, manually tightening the screws with a wrench during feed is cumbersome, increasing maintenance costs and downtime, and impacting production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the feed cover used in the general tank truck feed port in the prior art is sealed by six screws. Although the tank cover can be fixed, it is necessary to manually tighten the screws with a wrench during the feeding process. The operation of opening and closing the feed cover is cumbersome, which increases maintenance costs and downtime, and affects production efficiency. Therefore, we propose a new tank cover structure for the tank truck feed port.

[0004] To achieve the above objectives, this application adopts the following technical solution: a tanker truck filling port cover structure, including a tank cover body and an opening and closing auxiliary wall shafted to the upper arm of the tank cover body. The side wall of the tank cover body has multiple sets of snap-fit ​​grooves, which are used to match a six-claw for snap-fit. An auxiliary handle is installed on the upper edge of the tank cover body. A positioning rib is fixedly connected to the lower wall of the tank cover body. A sealing ring is fixedly connected to the outer wall of the positioning rib. An active channel is opened on the upper wall of the tank cover body where the auxiliary handle is installed. The auxiliary handle is slidably connected to the inner wall of the active channel. The lower end of the active channel passes through the tank cover body. A lower connecting rod is slidably connected to the lower wall of the auxiliary handle. A central rotating rod is shaft-connected to the lower end of the lower connecting rod.

[0005] Furthermore, the central rotating rod is rotatably connected to the lower opening of the movable channel. One end of the central rotating rod protrudes from the lower opening of the movable channel to push the sealing ring, causing it to deform. By pulling the auxiliary handle in conjunction with the central rotating rod, the sealing ring is pushed, causing local deformation of the sealing ring. The pressure inside the tank is quickly released through the deformation gap of the sealing ring, while simultaneously breaking the adhesion between the sealing ring and the tank truck's feeding port, significantly reducing the opening resistance.

[0006] Furthermore, an installation block is fixedly connected to the inner wall of the active channel, and a return spring is fixedly connected to the upper wall of the installation block. The upper wall of the return spring is fixedly connected to the bottom of the auxiliary handle.

[0007] Furthermore, in the relaxed state of the reset spring, the central rotating rod is attached to the outer wall of the sealing ring. When the auxiliary handle is pulled, the auxiliary handle stretches the reset spring to store force. After the auxiliary handle is released, the reset spring releases its elastic force and pushes the auxiliary handle to slide down along the active channel to reset.

[0008] Furthermore, an elastic cavity is provided at the inner edge of the sealing ring, and a rubber elastic block is fixedly connected to the inner wall of the elastic cavity.

[0009] Furthermore, multiple sets of the rubber elastic blocks are provided, and all sets of the rubber elastic blocks are evenly distributed around the inner wall of the elastic cavity.

[0010] The technical effects and advantages of this utility model are as follows: In this invention, when opening, first rotate the six-claw structure of the tank truck's filling port to disengage it from the snap-fit ​​groove of the tank cover body. Then, grasp the auxiliary handle on the edge of the tank cover body and pull it upward. The auxiliary handle slides up along the movable channel of the tank cover body and compresses the reset spring on the mounting block inside the movable channel. At the same time, it drives the lower connecting rod on the lower wall of the auxiliary handle to move upward. The lower connecting rod pulls the central rotating rod connected to the lower end shaft to rotate around the lower opening of the movable channel. The protruding part of the central rotating rod pushes the sealing ring outside the positioning rib on the lower wall of the tank cover body. The rubber elastic block in the elastic cavity of the sealing ring deforms, allowing the pressure inside the tank to be released through the gap. Then, with the help of the opening and closing auxiliary wall fulcrum connected to the upper arm shaft of the tank cover body, the tank cover body is lifted to complete the opening. No screws need to be turned throughout the process, which greatly shortens the operation time. This solves the problem that the filling cover used in the existing common tank truck filling ports is closed by six screws. Although the tank cover can be fixed, it still requires manual use of a wrench to turn the screws during the filling process. The operation of opening and closing the filling cover is cumbersome, which increases maintenance costs and downtime, and affects production efficiency. Attached Figure Description

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] Reference Figures 1-5 As shown, to address the issue that the existing standard tank truck filling port uses a filling cover secured by six screws, which, while providing a secure seal, requires manual tightening with a wrench during filling, making the operation cumbersome, increasing maintenance costs and downtime, and impacting production efficiency, the following preferred technical solution is provided: A tanker truck filling port cover structure includes a tank cover body 1. The device uses the tank cover body 1 as the core sealing component. An auxiliary wall 2 connected to the upper arm shaft of the tank cover body 1 provides a force-saving fulcrum for opening and closing the tank cover body 1, facilitating manual lifting and closing. Multiple sets of snap-fit ​​grooves 3 are opened on the side wall of the tank cover body 1 to match the six-claw structure of the tanker truck filling port, replacing the traditional screw fixing of the tank cover body 1. An auxiliary handle 4 on the upper edge of the tank cover body 1 is convenient for gripping and operation, and can be linked to the internal structure to achieve pressure relief. A positioning rib fixed to the lower wall of the tank cover body 1 is used for precise docking with the tanker truck filling port. A sealing ring 5 fixed to the outer wall of the positioning rib realizes the sealing of the tank cover body. The sealing of the body 1 and the tank truck's filling port is achieved by an active channel 6 on the upper wall of the tank cover body 1 corresponding to the installation location of the auxiliary handle 4, providing sliding space for the auxiliary handle 4. The lower connecting rod 7, which is slidably connected to the lower wall of the auxiliary handle 4, moves with the auxiliary handle 4 and is linked to the central rotating rod 8 connected to the lower end shaft of the lower connecting rod 7. The mounting block 9, which is fixed to the inner wall of the active channel 6, provides fixed support for the return spring 10. The upper end of the return spring 10 is fixed to the bottom of the auxiliary handle 4, enabling the auxiliary handle 4 to automatically return to its original position. The elastic cavity 11, which is opened on the inner edge of the sealing ring 5, works in conjunction with multiple sets of rubber elastic blocks 12 fixed to the inner wall of the elastic cavity 11 to enhance the sealing elasticity and pressure relief deformation capability of the sealing ring 5. The movable channel 6 of the can lid body 1 runs through the upper and lower walls of the can lid body 1. The auxiliary handle 4 is slidably connected to the inner wall of the movable channel 6. The lower wall of the auxiliary handle 4 is slidably connected to the lower connecting rod 7. The lower end of the lower connecting rod 7 is axially connected to the central rotating rod 8. The central rotating rod 8 is rotatably connected to the lower opening of the movable channel 6. One end of the central rotating rod 8 protrudes from the opening of the movable channel 6 and fits against the outer wall of the sealing ring 5. When the main body 1 of the can lid needs to be opened, pull the auxiliary handle 4 upwards. The auxiliary handle 4 slides upwards along the movable channel 6, driving the lower connecting rod 7 to move upwards simultaneously. The lower connecting rod 7 pulls the central rotating rod 8 to rotate around the pivot of the lower opening of the movable channel 6, causing the end of the central rotating rod 8 protruding from the opening of the movable channel 6 to push the sealing ring 5 upwards. After the main body 1 of the can lid is closed, the auxiliary handle 4 returns to its original position, and the central rotating rod 8 falls back to the state of fitting the sealing ring 5. Traditional can lids have high resistance when opened due to the pressure inside the can and the adhesion between the sealing ring and the can lid, requiring tools to pry it open. This structure, by pulling the auxiliary handle 4 and linking it with the central rotating rod 8 to push the sealing ring 5, causes the sealing ring 5 to deform locally. The pressure inside the can is quickly released through the deformation gap of the sealing ring 5, and at the same time, the adhesion between the sealing ring 5 and the tank truck's filling port is broken, greatly reducing the opening resistance. No additional tools are required, and it can be easily operated by a single person, further shortening the opening and closing time.

[0015] A mounting block 9 is fixedly connected to the inner wall of the movable channel 6. A return spring 10 is fixed to the upper wall of the mounting block 9. The upper end of the return spring 10 is fixed to the bottom of the auxiliary handle 4. When the return spring 10 is relaxed, the central rotating rod 8 is in contact with the outer wall of the sealing ring 5. When the auxiliary handle 4 is pulled, the auxiliary handle 4 stretches the return spring 10 to store force. After the auxiliary handle 4 is released, the return spring 10 releases its elasticity, pushing the auxiliary handle 4 to slide downwards along the movable channel 6 to reset. At the same time, it drives the lower connecting rod 7 and the central rotating rod 8 to reset, so that the central rotating rod 8 re-fits the sealing ring 5. There is no need for manual reset of the auxiliary handle 4, realizing an integrated operation of lifting to release pressure and automatic reset upon release, further simplifying the process. An elastic cavity 11 is formed on the inner edge of the sealing ring 5. Multiple sets of rubber elastic blocks 12 are fixed to the inner wall of the elastic cavity 11, and the multiple sets of rubber elastic blocks 12 are evenly distributed around the inner wall of the elastic cavity 11. When the tank cover body 1 is closed, the edge of the tank truck's feeding port squeezes the sealing ring 5, the elastic cavity 11 is compressed and contracts, and the rubber elastic blocks 12 inside the elastic cavity 11 deform and generate a reaction force, pushing the sealing ring 5 to fit tightly against the tank truck's feeding port, filling the tiny gaps. When the central rotating rod 8 pushes the sealing ring 5, the rubber elastic blocks 12 inside the elastic cavity 11 can deform quickly, providing sufficient deformation space for the sealing ring 5, which is convenient for pressure relief. Compared with the traditional solid sealing ring, the combination of the elastic cavity 11 and the rubber elastic blocks 12 makes the sealing ring 5 more adaptable to sealing. It can not only fit the tank truck's feeding port with different flatness through elastic compensation, improving the sealing reliability, but also deform quickly during pressure relief, avoiding the sealing ring 5 being difficult to push due to excessive rigidity, ensuring smooth pressure relief. The side wall of the can lid body 1 has multiple sets of snap-fit ​​grooves 3 for matching the six-claw structure snap-fit ​​of the tank truck's feeding port. The upper arm shaft of the can lid body 1 is connected to the opening and closing auxiliary wall 2. When closing the can lid body 1, the opening and closing auxiliary wall 2 acts as a fulcrum to easily close the can lid body 1 onto the tank truck's feeding port. Then, the six-claw structure of the tank truck's feeding port is rotated so that the six claws are engaged in the snap-fit ​​grooves 3, thus fixing the can lid body 1. When opening, the six claws are rotated in the opposite direction to disengage from the snap-fit ​​grooves 3. Then, the opening and closing auxiliary wall 2 is used to lift the can lid body 1. This replaces the traditional method of fixing by tightening six screws one by one. It can be operated by a single person without the need for multiple people to cooperate, improving the convenience of operation, reducing downtime, and increasing production efficiency.

[0016] Specifically, when opening, first rotate the six-claw structure of the tank truck's filling port to disengage it from the snap-fit ​​groove 3 of the tank cover body 1. Then, grasp the auxiliary handle 4 on the edge of the tank cover body 1 and pull it upwards. The auxiliary handle 4 slides upwards along the movable channel 6 of the tank cover body 1 and stretches the return spring 10 on the mounting block 9 inside the movable channel 6. At the same time, it drives the lower connecting rod 7 on the lower wall of the auxiliary handle 4 to move upwards. The lower connecting rod 7 pulls the central rotating rod 8 connected to the lower end shaft to rotate around the lower opening of the movable channel 6. The protruding part of the central rotating rod 8 pushes the sealing ring 5 outside the positioning rib on the lower wall of the tank cover body 1. The rubber elastic block 12 in the elastic cavity 11 inside the sealing ring 5 deforms, allowing the pressure inside the tank to be released through the gap. Then, with the help of the opening and closing auxiliary wall 2 connected to the upper arm shaft of the tank cover body 1, the tank cover body 1 is lifted to complete the opening. After feeding, the main body 1 of the tank cover is closed by opening and closing the auxiliary wall 2. The auxiliary handle 4 is released, and the return spring 10 rebounds to push the auxiliary handle 4, the lower connecting rod 7, and the central rotating rod 8 back to their original positions. The central rotating rod 8 re-fits the sealing ring 5. Finally, the six-claw structure is rotated to engage with the buckle groove 3 for fixation. At this time, the feeding port squeezes the sealing ring 5, and the rubber elastic block 12 in the elastic cavity 11 deforms to push the sealing ring 5 to seal tightly. No screws need to be turned throughout the process, which greatly shortens the operation time. This solves the problem that the feeding cover of the existing common tank truck feeding port is closed by six screws. Although the tank cover can be fixed, it still requires manual use of a wrench to turn the screws during the feeding process. The operation of opening and closing the feeding cover is cumbersome, which increases maintenance costs and downtime, and affects production efficiency.

[0017] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
