Description

Technical Field

[0001] This application relates to the field of end cap technology, specifically a vehicle-mounted steel tank end cap. Background Technology

[0002] Vehicle-mounted steel tanks typically refer to containers installed on vehicles for storage. They consist of a tank body and canisters, with the canisters located at both ends of the tank body and forming a crucial component. Currently, traditional canisters still present certain problems during use. For example, they lack a cushioning structure. During vehicle operation, the liquid inside the tank will transfer stress to the canisters due to inertia. Over time, this stress can damage the welded joints between the canisters and the tank body, leading to cracks. Utility Model Content

[0003] The purpose of this application is to provide a vehicle-mounted steel tank end cap to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: it includes a can, and the can has an inner plate that is slidably connected inside;

[0005] The inner plate has an inner groove on the side near the can, and a guide sleeve is fixedly connected to the inner plate inside the inner groove. A return spring is sleeved on the surface of the guide sleeve.

[0006] In a further embodiment, the inner plate is circular and the side of the inner plate away from the can is a funnel surface.

[0007] In a further embodiment, a guide groove is provided on the side of the can away from the inner plate, and the guide groove is slidably connected to the guide sleeve.

[0008] In a further embodiment, the surface of the guide sleeve is provided with an air guide hole, which communicates with the inner cavity of the guide sleeve.

[0009] In a further embodiment, the can has an internal mounting groove, and a sealing ring that mates with the inner plate is fitted inside the mounting groove.

[0010] In a further embodiment, both the can and the inner panel are made of stainless steel.

[0011] In a further embodiment, the outer diameter of the inner plate is the same as the inner diameter of the steel tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application utilizes an inner plate that slides inside the can. When the liquid inside the vehicle-mounted steel tank impacts the can due to inertia, the inner plate retracts into the can, buffering the impact stress and reducing the impact force on the can. This prevents damage to the weld between the can and the tank body due to prolonged high-frequency stress impacts, thus ensuring the lifespan of the connection between the can and the tank body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] A vehicle-mounted steel tank end cap includes a tank 1, with an inner plate 2 slidably connected inside the tank 1, such as... Figure 1 and Figure 2 As shown in this application, the can 1 is the end cap of the entire vehicle-mounted steel tank. The can 1 and the outer tank body can be combined to form a complete vehicle-mounted steel tank for sealing the two ends of the vehicle-mounted steel tank. The inner plate 2 is set inside the can 1. The inner plate 2 and the can 1 form a piston-like structure. When the liquid inside the vehicle-mounted steel tank is subjected to stress by inertia, the inner plate 2 will retract into the tank body to avoid the stress directly impacting the can 1. The materials of the can 1 and the inner plate 2 are both stainless steel to improve the corrosion resistance and strength of the vehicle-mounted steel tank.

[0022] An inner groove 3 is formed on the side of the inner plate 2 near the can 1. A guide sleeve 4 is fixedly connected to the inner plate 2 inside the inner groove 3. A return spring 5 is fitted on the surface of the guide sleeve 4. Figure 2 and Figure 4 As shown, the inner groove 3 is designed on the side of the inner plate 2 where the can 1 is located, and is used to install the guide sleeve 4. There are multiple guide sleeves 4 here. The guide groove 6 is designed on the can 1, and its number is the same as that of the guide sleeve 4. The guide sleeve 4 and the guide groove 6 are connected by a sliding rod, which can facilitate the sliding limit of the inner plate 2 when it is pushed back by the material due to inertial stress. The return spring 5 is designed on the surface of the guide sleeve 4 and is located between the can 1 and the inner plate 2. It is used to offset part of the stress when the inner plate 2 is retracted. When the inertial stress disappears, the inner plate 2 can be returned to its original position, so as to avoid the liquid inside the vehicle steel tank from directly acting on the can 1 without buffer due to inertia, and reduce the impact force on the can 1.

[0023] Furthermore, the inner plate 2 is circular, and the side of the inner plate 2 away from the can 1 is a funnel surface. The surface of the guide sleeve 4 has a vent hole 7, which communicates with the inner cavity of the guide sleeve 4. The can 1 has an installation groove 8 inside, and a sealing ring 9 that mates with the inner plate 2 is fitted inside the installation groove 8. Figure 1 , Figure 2 and Figure 3 As shown, the end of the inner plate 2 furthest from the can 1 is a funnel surface, which comes into contact with the liquid inside the vehicle-mounted steel tank. Due to its shape, it is easy for the material to come into contact with this surface and flow smoothly downwards, reducing the amount of liquid adhering to the inner plate 2. The air guide hole 7 is designed on the guide sleeve 4. One end of the guide sleeve 4 passes through the guide groove 6 to the outside of the can 1, which allows the air pressure between the can 1 and the inner plate 2 to enter and exit through the air guide hole 7, balancing the pressure between the can 1 and the inner plate 2.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
