[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the related art, the handle on the top of the dewar jar is hung by a hook, and then the dewar jar is tilted. With the help of gravity, it is firmly pressed against the support column, and then the cart is pushed to move the dewar jar back for transportation. However, this mode of transportation has the problem of insufficient stability. When encountering bumpy roads, the dewar jar will still collide with the fixed structure.

[0028] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a dewar tank cart. When it is needed, after hanging the dewar tank, the limit rod 22 is pulled out to surround the dewar tank, so as to prevent the dewar tank from bouncing and colliding due to bumps.

[0029] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Combination Figure 1-Figure 3The embodiment of the present application provides a dewar tank cart, including a cart device 1; the cart device 1 includes: a pulley 14 is arranged at the bottom of a base 11; a support column 12 is arranged at the top of the base 11; a fixed column 13 is arranged at the top of the base 11 and connected to the support column 12; a handle 15 is arranged on the outer wall of the fixed column 13; a snap ring 16 is arranged on the outer wall of the support column 12; a connecting column 17 is arranged at the top of the support column 12; a hook 18 is arranged on the outer wall of the connecting column 17; an auxiliary component 2 is arranged on the cart device 1, and the auxiliary component 2 includes: a column 21 is arranged on the outer wall of the support column 12; a limiting rod 22 is arranged inside the column 21; a through hole 23 is opened on the outer wall of the limiting rod 22 and the column 21, and a latch is arranged inside the through hole 23.

[0031] When in use, first hang the handle on the top of the Dewar jar on the hook 18 of the connection 17, and the bottom and the jar body are supported, fixed and limited by the clamp ring 16, pull the limiting rod 22 out of the column 21, and insert it into the other end of the column 21, and use the pin to insert the limiting rod 22 and the column 21 The through hole 23 is aligned, and the Dewar jar is further fixed to prevent the Dewar jar from bouncing up during transportation. Then, the handle 15 is used to push the cart device 1 to move the Dewar jar. The structure is simple and the operation is convenient, which greatly ensures the safety of the Dewar jar.

[0032] In some embodiments, a limiting block 24 is disposed on the outer side wall of the limiting rod 22. The setting of the limiting block 24 can prevent the limiting rod 22 from completely entering the column 21, which makes it inconvenient to remove.

[0033] In some embodiments, the outer wall of the column 21 is provided with a strong magnet 241 that cooperates with the limit block 24. After the limit rod 22 enters the column 21, the strong magnet 241 attracts the limit block 24 to prevent the limit rod 22 from coming out at will.

[0034] In some embodiments, a shell 25 is provided on the top of the base 11, and a rubber pad 26 is provided on the inner wall of the shell 25. The shell 25 with the rubber pad 26 is placed on the base 11 when not in use, and is placed between the limit rod 22 and the dewar tank when in use to increase the stability of the dewar tank.

[0035] In some embodiments, the inner wall of the limit rod 22 is provided with a roller 27, and the roller 27 is rotatably connected to the limit rod 22. The rotating roller 27 can reduce the friction between the limit rod 22 and the housing 25 when the limit rod 22 moves, and move and squeeze the housing 25 and the rubber pad 26 more smoothly.

[0036] In some embodiments, a fixing plate 28 is disposed on the top of the base 11, and the fixing plate 28 is rotatably connected to the base 11 via a torsion spring. The fixing plate 28 limits and fixes the housing 25 and the rubber pad 26. When they are needed, the housing 25 and the rubber pad 26 can be taken out by bending them to both sides, and then the fixing plate 28 will automatically rebound with the help of the torsion spring.

[0037] In some embodiments, the support column 12 is tilted so that the dewar can be tilted.

[0038] In some embodiments, the connecting column 17 is rotatably connected to the supporting column 12, and the number of the hooks 18 is multiple and the heights are different. The connecting column 17 is rotated, and a suitable hook 18 is selected to hang the dewar tank.

[0039] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
