Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment 1

[0026] One of the existing reinforcing ribs will produce more welding points at both ends of the reinforcing rib. During the loading and unloading process under pressure, the welding points will be affected by external pressure and internal pressure for a long time, which will cause metal fatigue and lead to cracking of the welding points, resulting in liquid leakage. In addition, during the driving process of the vehicle, the pressure of the liquid in the tank cannot be dispersed, which will also cause certain risks. Please refer to Figures 1-5 The utility model provides a kind of reinforcing rib structure for head for the embodiment, solve the technical problem that too many welding points between head and reinforcing rib appear liquid leakage after long time use, the device includes as support base head plate 1, head plate 1 one end is connected with the welding point connecting assembly 2 of separating welding point between head plate 1 and reinforcing rib. By head plate 1, the end portion of tank is closed, and the welding point connection between it and head plate 1 is separated by welding point connecting assembly 2.

[0027] In the traditional reinforcing rib welding process, more welding points are generated at both ends of the reinforcing rib. Similarly, in the process of loading and unloading under pressure, the welding points are subjected to external pressure and internal pressure for a long time, which causes metal fatigue and leads to cracking of the welding points, resulting in liquid leakage. In order to solve such problems, the welding point connection assembly 2 is proposed. The welding point connection assembly 2 comprises four connection seats 21 fixedly connected at one end of the head plate 1, a positioning rod 22 fixedly connected at the middle of the end of the connection seat 21, a connection plate 23 sleeved on the outside of the connection seat 21, a plurality of welding plates 26 fixedly connected on both sides of the end of the connection plate 23 away from the connection seat 21, a reinforcing rod seat 25 fixedly connected between the welding plates 26, a matching plate 24 fixedly connected above and below the end of the reinforcing rod seat 25 close to the connection plate 23, and a fixing bolt 27 spirally fixed on the inside of the positioning rod 22. The four positioning rods 22 pass through the four corners of the connection plate 23, and the fixing bolt 27 is spirally connected to the inside of the positioning rod 22 from the end of the connection plate 23 away from the connection seat 21.

[0028] In order to provide support to the tank body of the liquid tank, the top support rod 3 is fixedly connected to one end of the outside of the reinforcing rod seat 25, and the end of the top support rod 3 is fixedly connected to the pad 4.

[0029] During the fixing of the head plate 1, the connection plate 23 is slidably connected to the outside of the positioning rod 22 fixedly connected by the connection seat 21 of the head plate 1, and then the fixing bolt 27 is spirally connected to the inside of the positioning rod 22 passing through the connection plate 23, thereby achieving the fixation of the connection plate 23. Then the reinforcing rod seat 25 is welded to the surface of the connection plate 23 through the plurality of welding plates 26 on both sides, thereby achieving the connection of the reinforcing rod seat 25 and the connection plate 23, and transferring the welding points from the head plate 1 to the connection plate 23, which can avoid liquid leakage at the welding points. The positioning rod 22 fixedly connected to the inside of the head plate 1 through the connection seat 21 provides fixation for the connection plate 23, which can reduce the welding points on the head plate 1 and avoid liquid leakage at the welding points. In addition, the connection of the connection plate 23 can also replace the connection plate 23 after the welding points crack, thereby achieving the maintenance of the reinforcing rib of the liquid tank and improving the service life of the liquid tank.

[0030] Embodiment 2

[0031] On the basis of embodiment 1, embodiment 1 solves the technical problem of excessive welding points between the head and the reinforcing rib causing liquid leakage after a long time of use.

The supporting buffer assembly 5 includes a buffer groove 51 opened below one end of the reinforcing rod seat 25, a guide rod 52 is fixedly connected to the inner side of the buffer groove 51, a buffer spring 53 is sleeved on the outer side of the guide rod 52, a connecting slide 54 is slidingly connected to the inner side of the guide rod 52, a connecting rod 55 is rotatably connected to one side of the top end of the connecting slide 54, the bottom end of the buffer spring 53 is connected with the bottom end of the inner side of the buffer groove 51, the top end of the buffer spring 53 is connected with the bottom end of the inner side of the buffer groove 51, the top end of the connecting rod 55 is rotatably connected with the top supporting rod 3 close to one end of the base plate 4, and the end of the base plate 4 away from the connecting rod 55 is arc-shaped.

[0032] During the action of the welding point connecting assembly 2, when the tank body is subjected to pressure, the base plate 4 and the top supporting rod 3 are extruded, and when the base plate 4 and the top supporting rod 3 are extruded, the top supporting rod 3 is pressed downward to the connecting rod 55 rotatably connected thereto, and the connecting rod 55 is pressed downward to the connecting slide 54 rotatably connected to the other end thereof. At this time, the connecting slide 54 slides downward in the buffer groove 51, the guide rod 52 in the buffer groove 51 can play a guiding role, and the buffer spring 53 can play a buffering effect, which can provide an additional support for the top supporting rod 3 and also provide a buffering effect for the top supporting rod 3 with toughness, thereby prolonging the service life of the top supporting rod 3.
