[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Such as Figure 1 and Figure 2As shown in the figure, a clamping anti-slosh structure for a liquefied natural gas storage tank includes a storage tank 1. A connecting cylinder 2 adapted to it is sleeved on the outer wall of the storage tank 1. A tapered groove 3 is opened on the inner wall of the upper part of the connecting cylinder 2 along its axial direction, and the tapered groove 3 is distributed along the circumferential direction of the connecting cylinder 2. A contact seat 4 adapted to it and sleeving the storage tank 1 is arranged in the tapered groove 3. A plurality of notches 11 are opened in the circumferential direction of the contact seat 4, and the notches 11 are arranged along the axis direction of the contact seat 4. Under the cooperation of the contact seat 4 and the tapered groove 3 and the action of the notches 11, the outer wall of the storage tank 1 can be tightly abutted. An extension seat one 7 is arranged on the outer wall of the top surface of the connecting cylinder 2, and an extension seat two 8 adapted to the extension seat one 7 is arranged on the outer wall of the contact seat 4;

[0022] A plurality of internal threaded holes are opened on the end surface of the extension seat one 7. A positioning bolt 9 is passed through the corresponding extension seat two 8 at any two opposite internal threaded holes. A plurality of positioning holes 12 are also opened on the bottom surface of the connecting cylinder 2. Under the action of the positioning holes 12, the connecting cylinder 2 is fixedly connected to the mobile food truck through a connecting bolt.

[0023] As Figure 3 and Figure 4 shown, an installation groove 5 is opened on the inner wall of the contact seat 4 along its circumferential direction. A protective pad 6 is nested in the installation groove 5. The upper and lower ends of the protective pad 6 respectively extend to the top surface and the bottom surface of the contact seat 4. The protective pad 6 is made of polyurethane material. Through the setting of the protective pad 6, the phenomenon of scratching the surface of the storage tank 1 can be avoided during the downward movement of the contact seat 4.

[0024] As Figure 1 shown, a contact screw 10 for moving the contact seat 4 upward is also passed through the corresponding positions of other internal threaded holes on the bottom surface of the extension seat one 7. When disassembling the contact seat 4, first unscrew the positioning bolt 9, and then rotate the contact screw 10 to move upward, which can drive the contact seat 4 to move upward. In this way, the separation between the contact seat 4 and the tapered groove 3 can be achieved, and then the contact seat 4 can be taken out, which can facilitate and quickly disassemble the storage tank 1. Thus, after the natural gas in the storage tank 1 is used up, the replacement operation can be carried out.

[0025] As Figure 1 shown, the connecting cylinder 2 and the extension seat one 7, as well as the contact seat 4 and the extension seat two 8, are respectively integrally formed.

[0026] In specific use, first, under the action of the positioning holes 12, the connecting cylinder 2 is installed on the mobile food and beverage vehicle through the connecting bolts. Then, the storage tank 1 is loaded into the connecting cylinder 2. Next, the abutting seat 4 is sleeved into the conical groove 3 and moved downward. During the downward movement, under the action of the conical structure and the notch 11, the abutting seat 4 can be driven to contract, so that the protective pad 6 tightly abuts against the outer wall of the storage tank 1. Finally, the abutting seat 4 is fixedly connected through the cooperation of the positioning bolt 9 and the internal thread hole, so as to ensure the stability of the storage tank 1 during the movement of the mobile food and beverage vehicle and improve the use efficiency of the device.

[0027] The above description has been made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
