Description

Technical Field

[0001] This utility model relates to the field of oil capsule technology, specifically a foldable leak-proof oil capsule. Background Technology

[0002] Fuel bladders, also known as flexible fuel bladders, are containers for carrying fuel made of oil-resistant rubber sheeting. They are primarily used for carrying and refueling gasoline, diesel, and other fuels. Flexible fuel bladders are lightweight, impact-resistant, environmentally adaptable, and easy to use. However, in practical use, we have found that while convenient, their puncture resistance is relatively limited due to the bag-like structure made of oil-resistant rubber sheeting. When hanging or used in certain scenarios, the bladder casing is sometimes torn or punctured when it comes into contact with sharp objects, leading to fuel leakage. Furthermore, the flexible bag structure makes transportation and stacking inconvenient, sometimes causing deformation or even rupture of the lower bladders due to excessive expansion from compression.

[0003] Therefore, those skilled in the art now provide a foldable leak-proof oil capsule to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a foldable leak-proof oil bladder to solve the problems mentioned in the background art, which are generally not very effective at preventing punctures. When used in hanging or certain scenarios, the bladder often gets punctured or torn when it comes into contact with sharp objects, resulting in oil leakage. Furthermore, because the soft oil bladder has a soft bag structure, it is not very convenient for transportation and stacking, and sometimes the lower oil bladders may deform or even rupture due to excessive compression.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable leak-proof oil bladder, comprising a first rigid oil bladder, a second rigid oil bladder at the lower part of the first rigid oil bladder, the first rigid oil bladder and the second rigid oil bladder being connected at one side of their junction edge by a hinge, and an oil inlet at one corner of the upper end of the first rigid oil bladder.

[0007] The first hard oil bladder has a notch at one corner of its bottom, and the second hard oil bladder has a notch at one corner of its top, corresponding to the notch. An oil delivery hose is connected between the top of the notch and the bottom of the notch. The first hard oil bladder and the second hard oil bladder are connected to each other through the oil delivery hose.

[0008] The oil inlet and the oil delivery hose are located on the same side of the first hard oil bladder and the second hard oil bladder.

[0009] As a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the upper side of the first hard oil bladder has a relief groove, and the oil inlet is located inside the relief groove. An oil cap is also threadedly connected to the oil inlet.

[0010] As a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the top of the notch groove one and the bottom of the notch groove two respectively have oil guide ports that communicate with the inner cavity of their corresponding hard oil bladders. A sealing ring is provided around the oil guide port. The upper and lower ends of the oil delivery hose have connector tubes that abut against the sealing rings. A threaded cap is radially rotatably connected to the outer circumference of the connector tube, and the threaded cap is threadedly connected to the oil guide port.

[0011] As a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the first hard oil bladder and the second hard oil bladder are made of stainless steel or engineering plastic, and the outer walls of the first hard oil bladder and the second hard oil bladder also have a puncture-resistant coating layer.

[0012] As a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the first hard oil bladder has a first magnetic block on one side of its bottom, and the second hard oil bladder has a second magnetic block on one side of its top that is magnetically attracted to the first magnetic block.

[0013] As a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the first rigid oil bladder has a transparent observation window one along its height direction on one side, and the second rigid oil bladder has a transparent observation window two along its height direction on one side.

[0014] In a preferred embodiment of the foldable leak-proof oil bladder described in this utility model, the four corners of the first and second hard oil bladders are rounded.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This foldable leak-proof oil bag has the characteristics of simple structure, reasonable design and good practicality. By improving the existing soft oil bag and designing it into a foldable hard oil bag, and with both the first and second hard oil bags being regular rectangular box-shaped structures, and with the cooperation of notch groove one, avoidance groove and notch groove two, it presents a regular rectangular structure whether unfolded or folded, thus facilitating transportation, carrying and stacking; in addition, with the cooperation of hard oil bag shell and puncture-proof coating layer, it can effectively prevent the oil bag from being scratched / punctured and from being squeezed and expanded, which would lead to the oil bag rupture and leakage, making it suitable for widespread application.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual proportions. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figures 1-5 The diagram shown is a complete structural schematic of a foldable leak-proof oil bag according to this utility model. Please refer to [link / reference]. Figures 1-5 This embodiment of a foldable leak-proof oil bladder includes a first rigid oil bladder 100, a second rigid oil bladder 110 at the lower part of the first rigid oil bladder 100, and the first rigid oil bladder 100 and the second rigid oil bladder 110 are connected at one junction edge by a hinge 140. The upper corner of the first rigid oil bladder 100 has an oil inlet 120. The bottom corner of the first rigid oil bladder 100 has a notch 1001, and the top corner of the second rigid oil bladder 110 has a notch 1101 corresponding to the notch 1001. An oil delivery hose 200 is connected between the top of the notch 1001 and the bottom of the notch 1101, and the first rigid oil bladder 100 and the second rigid oil bladder 110 are interconnected through the oil delivery hose 200. The oil inlet 120 and the oil delivery hose 200 are located on the same side of the first rigid oil bladder 100 and the second rigid oil bladder 110.

[0026] The first rigid oil bladder 100 has a clearance groove 1002 on one side of its upper part, and the oil inlet 120 is located inside the clearance groove 1002. An oil cap 130 is threadedly connected to the oil inlet 120. It can be understood that oil can be added to the first rigid oil bladder 100 through the oil inlet 120, and the clearance groove 1002 can partially accommodate the oil inlet 120 and the oil cap 130, preventing the oil inlet 120 or the oil cap 130 from protruding outside the oil bladder shell, thereby facilitating subsequent transportation, carrying, and stacking. The top of notch 1001 and the bottom of notch 2101 each have an oil guide port 170 communicating with the inner cavity of their corresponding rigid oil bladders. A sealing ring 180 is provided around the oil guide port 170. The upper and lower ends of the oil delivery hose 200 have connector tubes 210 that abut against the sealing rings 180. A threaded cap 220 is radially rotatably connected to the outer periphery of the connector tube 210, and the threaded cap 220 is threadedly connected to the oil guide port 170. Similarly, the notch 1001 and notch 2101 can partially conceal the connecting structures such as the oil delivery hose 200 and the oil guide port 170, preventing the oil delivery hose 200 from protruding from the shell surface when the first rigid oil bladder 100 and the second rigid oil bladder 110 are unfolded or folded, thus preventing it from being squeezed. The first rigid oil bladder 100 and the second rigid oil bladder 110 are made of stainless steel or engineering plastic. The outer walls of the first rigid oil bladder 100 and the second rigid oil bladder 110 also have a puncture-resistant coating layer 400. It is understood that stainless steel and engineering plastic materials have excellent mechanical strength, are lightweight, and are impact-resistant. In order to further improve the puncture resistance of the oil bladder, the puncture-resistant coating layer 400 can be made of Kevlar fiber or nylon, etc. In particular, Kevlar fiber has good puncture resistance and tensile strength, which can further enhance the puncture resistance of the oil bladder. Specifically, in this embodiment, the existing soft oil bladder is improved and designed as a foldable hard oil bladder. Both the first hard oil bladder 100 and the second hard oil bladder 110 are regular rectangular box-shaped structures. With the cooperation of notch groove 1001, clearance groove 1002 and notch groove 1101, they present a regular rectangular structure whether unfolded or folded, which facilitates transportation, carrying and stacking. In addition, with the cooperation of hard oil bladder shell and puncture-proof coating layer 400, the oil bladder can be effectively prevented from being scratched / punctured or from being squeezed and expanded, which would cause the oil bladder to rupture and leak. It is suitable for widespread application. In addition, during actual refueling, the oil cap 130 can be opened directly, and the oil can be introduced into the first hard oil bladder 100 through the oil inlet 120. At the same time, excess oil can enter the second hard oil bladder 110 through the oil delivery hose 200. After the second hard oil bladder 110 is full, the oil that is added will continue to fill the first hard oil bladder 100.

[0027] Furthermore, as a preferred embodiment, the first rigid oil bladder 100 has a first magnetic block 330 on one side of its bottom, and the second rigid oil bladder 110 has a second magnetic block 310 on one side of its top that magnetically attracts and engages with the first magnetic block 330. It can be understood that after the first rigid oil bladder 100 and the second rigid oil bladder 110 are rotated and unfolded, the first magnetic block 330 and the second magnetic block 310 can attract and stabilize the upper and lower oil bladders, preventing them from freely rotating or swinging. When folding is required, they can be simply bent and stored away, making it simple and practical.

[0028] Furthermore, as a preferred embodiment, the first hard oil bladder 100 has a transparent observation window 150 along its height direction on one side, and the second hard oil bladder 110 has a transparent observation window 160 along its height direction on one side. The lower limit of the remaining oil volume in the oil bladder can be directly observed through the transparent observation window 160, and the upper limit of the oil bladder loading can be observed through the transparent observation window 150.

[0029] Furthermore, as a preferred embodiment, the four corners of the first hard oil bladder 100 and the second hard oil bladder 110 are rounded. The rounded corners reduce the risk of improper compression and impacts on the edges and corners of the oil bladder shells, making them easier to carry.

[0030] In summary, this embodiment of a foldable leak-proof oil bladder allows for direct opening of the oil cap 130 and introduction of oil into the first rigid oil bladder 100 via the oil inlet 120. Excess oil can simultaneously flow through the oil delivery hose 200 into the second rigid oil bladder 110. Once the second rigid oil bladder 110 is full, subsequent oil filling will continue to fill the first rigid oil bladder 100. When emptying oil, the oil in the second rigid oil bladder 110 flows directly into the first rigid oil bladder 100 through the oil delivery hose 200. Furthermore, during use… During the process, by improving the existing soft oil bladder, both the first hard oil bladder 100 and the second hard oil bladder 110 are regular rectangular box-shaped structures. With the cooperation of notch groove one 1001, clearance groove 1002 and notch groove two 1101, they present a regular rectangular structure whether unfolded or folded, thus facilitating transportation, carrying and stacking. With the cooperation of hard oil bladder shell and puncture-proof covering layer 400, the oil bladder can be effectively prevented from being scratched / punctured or from being squeezed and expanded, which would cause the oil bladder to rupture and leak.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
