DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0024] refer to Figure 1-6 A liquid oxygen storage tank with good protection comprises a base 1, a protective frame 2 is fixedly connected to the upper end surface of the base 1, a top plate 3 is fixedly connected to the top of the protective frame 2, a threaded rod 4 is internally threadedly connected to the top plate 3, and a support frame 5 is rotatably connected to the bottom end of the threaded rod 4, a groove 13 is provided on the upper end surface of the base 1, a first spring 14 is fixedly connected in the groove 13, a support plate 6 is fixedly connected to the top end of the first spring 14, a liquid oxygen storage tank body 8 is placed on the upper end surface of the support plate 6, a lower end surface of the support frame 5 abuts against the surface of the liquid oxygen storage tank body 8, a side surface of the support plate 6 is slidably connected and fits with the inner wall of the groove 13, a plurality of fixed plates 15 are fixedly connected in the groove 13, a connecting block 16 is rotatably connected between every two fixed plates 15, and a clamping plate 7 is rotatably connected to the top end of the connecting block 16.

[0025] By providing the abutment 5, when the abutment 5 moves downward and abuts against the surface of the liquid oxygen storage tank body 8, the liquid oxygen storage tank body 8 can be limited in upper and lower positions.

[0026] Furthermore, a hinge 10 is fixedly connected to the side of the protection frame 2 , and a protection door 9 is hingedly connected to the surface of the hinge 10 .

[0027] Furthermore, the protective door 9 and the side surface of the protective frame 2 are fixedly connected with a fixing block 11 , and a bolt 12 is arranged in the fixing block 11 .

[0028] Furthermore, a nut is threadedly connected to the surface of the bolt 12 , and one side of the nut abuts against the side surface of the fixing block 11 .

[0029] By providing the bolt 12 , when the nut is tightened on the bolt 12 , the protective door 9 can be closely attached to the surface of the protective frame 2 by clamping the two fixing blocks 11 .

[0030] Furthermore, a second spring 17 is fixedly connected in the groove 13 , and a top end of the second spring 17 is fixedly connected to a lower end surface of the connecting block 16 .

[0031] By providing the second spring 17 , when the liquid oxygen storage tank body 8 is not placed in the protection frame 2 , the four clamping plates 7 can always be in an open state under the action of the elastic force of the second spring 17 .

[0032] Furthermore, one side of the clamping plate 7 abuts against the side surface of the liquid oxygen storage tank body 8 , and the lower end surface of the support plate 6 abuts against the side surface of the connecting block 16 .

[0033] The working principle of the utility model is as follows: first, the staff opens the protective door 9 and places the liquid oxygen storage tank body 8 on the support plate 6. Then, the staff rotates the threaded rod 4 clockwise to drive the bracket 5 to move downward. The bracket 5 abuts against the surface of the liquid oxygen storage tank body 8 and pushes downward. The liquid oxygen storage tank body 8 pushes the support plate 6 downward, and the support plate 6 drives the connecting block 16 to rotate. The connecting block 16 can drive the clamping plate 7 to move relatively and clamp the hydraulic storage tank body. When the clamping plate 7 abuts against the surface of the hydraulic storage tank body, the staff cannot rotate the threaded rod 4. The whole device can stably limit the liquid oxygen storage tank body 8. After the liquid oxygen storage tank body 8 is taken out, the clamping plate 7 and the support plate 6 can be driven to return to their original positions under the action of the elastic force of the first spring 14 and the second spring 17 to perform the next work.

[0034] Compared with the prior art, the support frame 5 can move up and down and limit the liquid oxygen storage tank bodies 8 of various heights, thereby improving the practicability of the device.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
