[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. 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.

[0036] Embodiment one

[0037] Referring to Figures 1-4 A kind of anti-collision liquefied gas steel bottle, including main assembly 1, the main assembly 1 includes: bottle body 11, its top is provided with valve seat 12;The bottle body 11 is provided with protection assembly 2, and the protection assembly 2 includes: protective cover 21, is set to the bottle body 11 outside;Connecting block 22 is fixedly connected to the bottle body 11 outer side wall;Fixed groove 23 is opened in the connecting block 22 outer side wall;Frame 24 is fixedly connected to the protective cover 21 outer side wall;Placing groove 241 is opened in the frame 24 middle part;Cavity 251 is symmetrically opened in the frame 24 inside, and the cavity 251 and the placing groove 241 are mutually through;Fixed block 25 is symmetrically and slidingly connected in the cavity 251;Spring 26 is fixedly connected between the fixed block 25 and the cavity 251 inner side wall;Sliding rod 27 is fixedly connected to the fixed block 25 top, and the sliding rod 27 top is penetrated and extends to the frame 24 top, and the frame 24 is opened with the through slot that the sliding rod 27 can move. The protection assembly 2 is symmetrically provided with multiple groups, and at least two groups are provided. The protective cover 21 outer side wall is fixedly connected with rubber pad 4.

[0038] In use, the protective cover 21 protects the surface of the bottle body 11, and when the bottle body 11 is transported or used, the protective cover 21 can disperse the collision energy and reduce the impact force directly received by the bottle body 11. The protective cover 21 is prone to deformation after being subjected to external force for a long time, and the ability of the deformed protective cover 21 to buffer and disperse impact force will decrease after collision. Therefore, the staff pulls the two slide rods 27 outward, and the fixing block 25 drives the fixing block 25 to disengage from the fixing groove 23 and retract into the cavity 251. The fixing block 25 releases the limiting of the connecting block 22. At this time, the staff lifts the bottle body 11 to take the bottle body 11 out of the protective cover 21, so as to facilitate the replacement of the new protective cover 21. When it is necessary to install a new protective cover 21, the staff pulls the slide rod 27 to the two sides again, and the fixing block 25 retracts into the cavity 251 and presses the spring 26. At this time, the bottle body 11 is placed in the protective cover 21, and the connecting block 22 outside the bottle body 11 is placed on the placing groove 241. Then, the slide rod 27 is loosened, and the spring 26 drives the fixing block 25 to be inserted into the fixing groove 23, so as to fix the connecting block 22, complete the replacement of the protective cover 21, and facilitate the protection of the bottle body 11. The protective assembly 2 is provided in multiple groups, so that the bottle body 11 has multiple connecting blocks 22 outside the bottle body 11 to connect the bottle body 11 and the protective cover 21, thereby enhancing the firmness of the protective cover 21 after being connected with the bottle body 11. The rubber pad 4 outside the protective cover 21 has good elasticity and flexibility, and can further absorb and disperse the impact force when the bottle body 11 is subjected to collision or vibration. Compared with the protective cover 21 alone, the rubber pad 4 can more effectively reduce the influence of external force on the bottle body 11 and the internal gas, and reduce the risk of damage or gas leakage of the bottle body 11 caused by collision.

[0039] Embodiment two

[0040] According to the basis of embodiment one, an auxiliary function is added.

[0041] Referring to Figures 1-4 , the fixing block 25 is provided with an inclined surface. The fixing block 25 is fixedly connected with a sliding block 3 at the bottom, and the cavity 251 is provided with a sliding groove 31 at the bottom. The sliding block 3 is slidably connected in the sliding groove 31. The bottle body 11 is provided with universal wheels 5 at the bottom.

[0042] The slope on the fixed block 25 enables the worker to fix the protective cover 21 and the bottle body 11 without pulling the slide rod 27 in advance: the worker directly places the bottle body 11 inside the protective cover 21, the connecting block 22 moves downward and is inserted into the placing groove 241, the connecting block 22 pushes the fixed block 25 into the cavity 251 after the edge of the connecting block 22 contacts the slope of the fixed block 25, the spring 26 is extruded by the fixed block 25, when the bottom of the connecting block 22 contacts the top of the placing groove 241, at this time, the fixed block 25 is located at the same horizontal line with the fixed groove 23, the spring 26 pops the fixed block 25 into the fixed groove 23, and the automatic limiting of the connecting block 22 is completed, thereby improving the convenience of the worker when replacing the protective cover 21. When the fixed block 25 moves in the cavity 251, the sliding block 3 slides in the sliding groove 31, the sliding block 3 guides the movement of the fixed block 25, avoids the whole movement of the fixed block 25 out of the cavity 251, and thus affects the stability of the connecting block 22 after being connected. The universal wheel 5 facilitates the worker to move the bottle body 11 with large weight, increases the convenience of the worker when transporting the bottle body 11, and the universal wheel 5 is provided with a self-locking structure, after the bottle body 11 is moved, the worker starts the self-locking structure of the universal wheel 5 to lock the universal wheel 5, and avoids the random shaking of the bottle body 11 when being used.

[0043] The self-locking structure in the universal wheel 5 is a conventional technical means, for example, a brake device is installed on the support of the universal wheel 5, the brake pedal is operated by foot, the brake block contacts the edge of the wheel or the wheel shaft, friction is generated, thereby preventing the wheel from rotating, and a locking device is provided, after braking, the brake block is locked in the braking position to prevent it from being accidentally released. As long as the self-locking of the universal wheel 5 can be achieved, the specific structure is not described here.

[0044] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
