DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawings.

[0025] For convenience, the direction from the bottom wall toward the opening is referred to as "upward" or similar terms, and the direction from the opening toward the bottom wall is referred to as "downward" or similar terms.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a protective cover 100 for a gas cylinder, comprising a bottom wall 1, a side wall 2 connected to the bottom wall 1 and extending upward, wherein the side wall 2 and the bottom wall 1 together form a cavity 3 for accommodating a gas cylinder with an open top and a hollow interior. A counterweight mechanism 5 for lowering the center of gravity of the gas cylinder is selectively provided in the cavity 3, and the counterweight mechanism 5 is used to receive the gas cylinder and lower the center of gravity of the gas cylinder. In this way, the gas cylinder can be stably placed in the protective cover 100, thereby preventing the gas cylinder from tipping over and causing damage to the gas cylinder.

[0027] In this embodiment, if Figure 1 As shown, the counterweight mechanism 5 includes a counterweight platform 51 of a platform-shaped structure adapted to the cavity 3, and an inwardly recessed receiving portion 52 is formed on the counterweight platform 51, and the receiving portion 52 is configured to be complementary to the shape of the gas cylinder. In this way, when the gas cylinder is placed in the receiving portion 52, the gas cylinder can fit together with the receiving portion 52, so that the gas cylinder can be stably placed in the receiving portion 52. In addition, in this process, the gravity at the bottom of the gas cylinder can also be increased, so that the center of gravity of the gas cylinder is lowered. In this way, the gas cylinder is prevented from tipping over and causing damage to the gas cylinder.

[0028] In one embodiment, Figure 1 As shown, the protective cover 100 further includes a folding mechanism 4 disposed on the free end of the side wall 2, and the folding mechanism 4 is used to fold the opening formed by the side wall 2, so as to place the gas cylinder in the cavity 3 in a sealed manner, and prevent the gas cylinder from being separated from the cavity 3 along the opening. In this way, the gas cylinder is prevented from being worn during use, and the gas cylinder is protected.

[0029] It should be noted that the protective cover 100 is made of a flexible material. Specifically, the bottom wall 1, the side wall 2, and the folding mechanism 4 are all made of a flexible material. In this way, the protective cover 100 is easy to fold and store. Moreover, when it is put on the gas cylinder, it can fit with the gas cylinder to further protect the gas cylinder.

[0030] In this arrangement, when in use, the bottom wall 1 and the side wall 2 are combined together, and the bottom wall 1 and the side wall 2 form a cavity 3 together. Then, the gas cylinder is placed into the cavity 3 along the opening formed by the side wall 2. At this time, the retracting mechanism 4 is pulled so that the opening formed by the side wall 2 shrinks inward along the circumferential direction until it contacts the wall surface of the gas cylinder. In this way, the gas cylinder can be placed inside the side wall 2, and the bottom wall 1 and the side wall 2 can fit the wall surface of the gas cylinder. In this way, the gas cylinder is protected.

[0031] In one embodiment, Figure 1 As shown, the folding mechanism 4 includes a sleeve 41 arranged along the free end of the side wall 2, and a drawstring 42 passing through the sleeve 41. The sleeve 41 is arranged as a hollow structure, which is used to form a movement path of the drawstring 42. At the same time, the sleeve 41 is made of a flexible material, and an outlet (not shown in the figure) is formed on the sleeve 41 for the drawstring 42 to pass out to the outside. It should be noted that, as shown in FIG. Figure 2 As shown, both ends of the drawstring 42 pass through the outlet and are located outside.

[0032] In this arrangement, when the opening formed by the side wall 2 needs to be closed, the drawstring 42 is fixed, and a force of inward contraction is applied to the sleeve 41 from the outlet. In this process, the sleeve 41 will continue to contract inward along the drawstring 42. At the same time, the drawstring 42 will continue to move to the outside. At this time, the opening can be bundled in an optional manner by the drawstring 42 located outside, so as to seal the cavity 3 in an optional manner. In this way, the closing of the opening of the side wall 2 can be completed.

[0033] According to a preferred embodiment of the present invention, Figure 2 As shown, the two ends of the drawstring 42 are fixedly connected to each other outside the sleeve 41. In this way, the drawstring 42 can be stably arranged in the sleeve 41, thereby preventing the drawstring 42 and the sleeve 41 from being separated from each other during the movement of the sleeve 41.

[0034] Figure 3 The structure of the second embodiment of the folding mechanism 4 of the utility model is shown. Figure 1Compared with the folding mechanism 4 shown in the figure, the difference is that one end of the drawstring 42 is fixedly arranged on one side of the outlet, and the other end of the drawstring 42 passes through the other side of the outlet. In this way, the sleeve 41 can move along the drawstring 42 and complete the folding of the opening, and after folding, the opening can be bundled in an optional manner through the external drawstring 42.

[0035] According to a preferred embodiment of the present invention, the sleeve 41 is made of the same material as the side wall 2 and is formed by folding the free end of the side wall 2 to one side. In this way, the sleeve 41 and the side wall 2 can form an integrated structure, thereby increasing the connection strength and making the connection between the sleeve 41 and the side wall 2 more stable.

[0036] In one embodiment, Figure 1 As shown, an observation port 21 is formed through the side wall 2, and the observation port 21 is used to observe information on the surface of the gas cylinder, so as to identify the gas cylinder. In this way, the gas cylinder can be accurately selected during use.

[0037] In one embodiment, Figure 1 As shown, the protective cover 100 further includes at least one handle 22 fixedly disposed on the side wall 2 for carrying the protective cover 100 and the gas cylinder in the protective cover 100. In this way, when the gas cylinder needs to be transferred or transported, the handle 22 can be used to carry the gas cylinder in the protective cover 100. Thus, a fulcrum for applying a force can be formed.

[0038] In this embodiment, two handles 22 are provided and symmetrically distributed on the side wall 2 along the gas cylinder. In this arrangement, when the protective cover 100 and the gas cylinder in the protective cover 100 are carried by the handles 22, the two handles 22 can evenly bear the force generated by the protective cover 100 and the gas cylinder in the protective cover 100, thereby stably transferring and carrying the gas cylinder.

[0039] Among them, Figure 1 As shown, the handle 22 is configured as a strip structure, and the two ends of the handle 22 are respectively connected to the side wall 2 in a fixed manner. At the same time, after the handle 22 and the side wall 2 are connected to each other, the handle 22 also forms a margin for holding. Specifically, the length of the handle 22 is greater than the length between the two fixed points. In this way, when transferring or carrying the gas cylinder, the handle 22 can be held and a force can be applied to the handle 22, so as to transfer or carry the gas cylinder.

[0040] In one embodiment, Figure 1As shown, the protective cover 100 further includes a reflective strip 23 disposed on the side wall 2, and the reflective strip 23 is made of any material having reflective properties. In this way, the protective cover 100 can reflect the light received when irradiated by a light source, thereby playing a role in marking the position of the protective cover 100. In this embodiment, the reflective strip 23 is arranged around the side wall 2. In this way, the reflection area can be increased, thereby further accurately marking the position of the protective cover 100.

[0041] In one embodiment, a wear-resistant layer is provided on the outer surface of the bottom wall 1. In this way, the wear resistance of the bottom wall of the protective cover 100 can be increased, so that the bottom wall 1 of the protective cover 100 still has the function of receiving the gas cylinder after multiple frictions, thereby protecting the gas cylinder. In this embodiment, the wear-resistant layer is set as a nitrile coating.

[0042] The protective cover 100 for a gas cylinder according to the present invention operates as follows.

[0043] First, the protective cover 100 is unfolded so that the bottom wall 1 and the side wall 2 form a cavity 3, and the folding mechanism 4 is located at the free end of the side wall 2. At the same time, the counterweight mechanism 5 is placed into the cavity 3 along the opening formed by the side wall 2, and the counterweight platform 51 and the bottom wall 1 are in contact with each other.

[0044] Secondly, the gas cylinder is placed into the cavity 3 along the opening formed by the side wall 2, and the bottom of the gas cylinder is located in the receiving portion 52 and is attached to the wall surface of the receiving portion 52. At this time, the gas cylinder can be located in the cavity 3.

[0045] Then, the drawstring 42 is fixed, and a force for inward contraction is applied to the sleeve 41 from the outlet. In this way, the sleeve 41 will continue to contract inward along the drawstring 42 until the sleeve 41 and the gas cylinder are in contact with each other. In this process, the drawstring 42 will continue to move to the outside. At this time, the opening can be tied up by the drawstring 42 located outside, so that the gas cylinder is stably set in the protective cover 100. In this way, the protection of the gas cylinder is achieved by the protective cover 100, and the gas cylinder is prevented from tipping over by the counterweight mechanism 5.

[0046] When the gas cylinder needs to be transferred or carried, the handle 22 is held and a force is applied to the handle 22 to transfer or carry the gas cylinder. Thus, the transfer or carrying work of the gas cylinder is completed.
