[0001] This application relates to the field of solid hydrogen storage technology, specifically to a handle for a solid hydrogen storage bottle and the solid hydrogen storage bottle itself. Background Technology
[0002] Against the backdrop of the booming development of the national hydrogen energy industry and the diversified layout of hydrogen energy storage, solid alloy hydrogen energy storage, as a key technology, has initially achieved market scale with continuous policy support. Among them, hydrogen electric vehicles, with their significant advantages such as zero emissions, long range, and fast refueling, are accelerating their market promotion, and the deployment of various public facilities is increasing daily.
[0003] However, with the large-scale operation of hydrogen-powered electric vehicles, the safety hazards of solid alloy hydrogen storage cylinders have gradually emerged. In practical applications, investigations into multiple hydrogen leak incidents have shown that the cylinder valve area becomes the primary stress point during the disassembly, assembly, and refilling process. Long-term, repeated stress causes the threaded interface of the valve to loosen, leading to hydrogen leakage. This not only exacerbates interface wear but also poses serious safety risks.
[0004] In view of this, it is necessary to design a handle for a solid hydrogen storage cylinder and a solid hydrogen storage cylinder to solve one of the above problems. Summary of the Invention
[0005] This application provides a handle for solid hydrogen storage cylinders. The handle of this application allows for convenient handling of solid hydrogen cylinders and avoids stress on the cylinder valve, thus solving the problem of hydrogen leakage.
[0006] To achieve the above objectives, the technical solution provided in this application is as follows: This application provides a handle for a solid hydrogen storage cylinder. The handle includes a retaining ring, which includes a first semi-ring and a second semi-ring. Each of the first and second semi-rings includes a body, a first docking structure, and a second docking structure located at both ends of the body. The first docking structure of the first semi-ring and the second docking structure of the second semi-ring are detachably connected by a fastener, and the second docking structure of the first semi-ring and the first docking structure of the second semi-ring are detachably connected by a fastener, so that the first and second semi-rings are arranged in a ring. The first docking structure and / or the second docking structure are provided with a mounting portion for installing a lifting component.
[0007] Furthermore, the first docking structure includes a docking portion connecting the body, the mounting portion being located on the side of the docking portion away from the body, and the fastener being mounted on the docking portion and the second docking structure.

[0009] Furthermore, the docking part and the second docking structure are respectively provided with a fixing hole that extends along the docking direction for the fixing member to pass through, and the diameter of the fixing hole is not greater than two-thirds of the width of the docking part.
[0010] Furthermore, the width of the body is greater than the thickness of the body, and the thickness of the docking portion and the second docking structure are both greater than the thickness of the body.
[0011] Furthermore, the length of the mounting portion is not greater than the length of the docking portion.
[0012] Furthermore, the mounting part is provided with a mounting hole that extends through the axial direction of the retaining ring, and the diameter of the mounting hole is not greater than half the thickness of the mounting part.
[0013] Furthermore, the handle also includes an auxiliary retaining ring that matches and is installed with the mounting hole, and the auxiliary retaining ring and the mounting hole are fitted without any clearance.

Detailed Implementation
[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0023] It should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only to simplify the description of this application and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.
[0024] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts may be exaggerated relative to other structural parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.
[0025] This application provides a handle 100 for a solid hydrogen storage cylinder and a solid hydrogen storage cylinder, if any Figure 4 As shown, the solid hydrogen storage cylinder includes a cylinder body 200 and a handle 100 for the solid hydrogen storage cylinder. Specifically, the cylinder body 200 includes a cylinder body, a bottleneck at the opening of the cylinder body, and a slot provided on the bottleneck. The handle 100 is engaged in the slot, facilitating the operator's retrieval of the solid hydrogen storage cylinder. The handle 100, installed on the solid hydrogen storage cylinder, allows the operator to avoid contact with the cylinder valve when handling the solid hydrogen storage cylinder, thereby preventing the risk of hydrogen leakage. Furthermore, the handle 100 is fixed in the slot to ensure stability and safety during the lifting process.
[0026] like Figure 1 and Figure 3As shown, the handle 100 includes a retaining ring 1 for mounting the lifting component. When retrieving the bottle, the high tensile strength lifting component is installed on the mounting component, and the operator pulls the lifting component to pick up and put down the solid hydrogen storage bottle, changing the force point between the handle 100 and the bottle body, thus preventing the valve of the solid hydrogen storage bottle from loosening.
[0027] Specifically, the retaining ring 1 includes a first half-ring 10 and a second half-ring 20. Both the first half-ring 10 and the second half-ring 20 include a body 11, a first docking structure 12 and a second docking structure 13 disposed at both ends of the body 11, and the mounting part is disposed on the first docking structure and / or the second docking structure.
[0028] The first docking structure 12 of the first semi-ring 10 and the second docking structure 13 of the second semi-ring 20 are detachably connected by a fastener 14. The second docking structure 13 of the first semi-ring 10 and the first docking structure 12 of the second semi-ring 20 are detachably connected by a fastener 14 so that the first semi-ring 10 and the second semi-ring 20 form a ring. That is, the first semi-ring 10 and the second semi-ring 20 are centrally symmetrical about the center of the retaining ring 1. The structures of the first semi-ring 10 and the second semi-ring 20 are completely identical, which simplifies the production process, adapts to large-scale production, reduces production costs, and adopts a modular design with no complex parts, reducing assembly errors.
[0029] The handle 100 of this application can be easily installed on the neck of a solid hydrogen storage cylinder by means of the first semi-ring body 10 and the second semi-ring body 20 being detachable via the fastener 14. The first docking structure 12 and the second docking structure 13 are installed on the body 11 along the radial direction of the ring, without affecting the ring shape formed.
[0030] For ease of clear description, the thickness of the first semi-ring 10 and the second semi-ring 20 along the radial direction of the ring is defined as the thickness, the width along the axial direction of the ring is defined as the width, and the length along the circumferential direction of the retaining ring is defined as the length.
[0031] The width of the body 11 is greater than the thickness of the body 11. Since the width direction of the body 11 is the same as the direction in which the handle 100 lifts the solid hydrogen storage bottle, the width of the body 11 is larger, which can improve the lifting strength of the retaining ring 1.
[0032] In this embodiment, the width of the body 11 is twice the thickness of the body 11. Preferably, the width of the body 11 is 8mm and the thickness of the body 11 is 4mm.
[0033] In a preferred embodiment of this application, the first docking structure 12 includes a docking portion 121 that connects to the body 11, the mounting portion 122 is located on the side of the docking portion 121 away from the body 11, and the fixing member 14 is installed on the docking portion 121 and the second docking structure 13. When the first half-ring 10 and the second half-ring 20 dock, the docking portion 121 docks with the second docking structure 20.
[0034] Furthermore, the thickness of the docking part 121 and the second docking structure 20 is greater than the thickness of the body 11, so as to ensure the structural strength of the handle 1 when lifting the bottle body.
[0035] like Figure 2 As shown, the docking part 121 and the second docking structure 20 are respectively provided with a fixing hole 15 that passes through along the docking direction for the fixing member 14 to pass through. The diameter of the fixing hole 15 is not greater than two-thirds of the width of the docking part 14, so as to ensure the structural strength of the docking part 121 and the second docking structure 13, thereby ensuring the structural strength of the handle and the safety of the lifting process. Preferably, the diameter of the fixing hole 15 is 4.5mm.
[0036] In this embodiment, both fasteners 14 are installed from the direction of the second docking structure 13, that is, the installation directions of the two fasteners 14 are opposite, thus achieving a self-locking effect.
[0037] Furthermore, the thickness of the mounting portion 122 is greater than the thickness of the docking portion 121, and the second docking structure 13 is located in the space formed by the docking portion 121 and the mounting portion 122. When the first docking structure 12 and the second docking structure 13 are docked, it facilitates the positioning of the docking portion 121 and the second docking structure 13. The mounting portion 122 can also limit the second docking structure 13.
[0038] Preferably, the thickness of the mounting part 122 is not less than twice the thickness of the docking part 121. After the first docking structure 12 and the second docking structure 13 are docked, the second docking structure 13 does not protrude from the first docking structure 12, and the overall appearance is relatively neat.
[0039] The length of the mounting part 122 is not greater than the length of the docking part 121. Since the mounting part 122 is used to install the lifting structure, the mounting part 122 of a suitable size can ensure the strength of the first docking structure 12 on the one hand, and reduce the pulling force of lifting the bottle body on the other hand. During the handling process, it can be easily operated by a single person, improving the safety of lifting the bottle body and thus effectively improving the efficiency of operation and maintenance.
[0040] Of course, when the first semi-ring 10 and the second semi-ring 20 are arranged in a ring, the first docking structure 12 and the second docking structure 13 are completely symmetrical and identical, which is also within the scope of protection of this application.
[0041] As another preferred embodiment of this application, the mounting part is provided with a mounting hole 123 that extends through the axial direction of the retaining ring 1. The diameter of the mounting hole 123 is not greater than half the thickness of the mounting part 122, so as to ensure the strength of the mounting part 122 itself and thereby improve the structural strength of the entire handle 100.
[0042] As another preferred embodiment of this application, such as Figure 3 As shown, the handle 100 also includes an auxiliary mounting component 2 that is installed in conjunction with the mounting hole 123. The auxiliary mounting component 2 is used to connect the mounting hole 123 and the lifting component. If the lifting component is a rope, the rope passes through the mounting hole to fix the lifting component.
[0043] Preferably, the auxiliary mounting component 2 and the mounting hole 123 are fitted without any clearance, so that there is a frictional force between the auxiliary mounting component 2 and the mounting hole 123 along the axial direction of the retaining ring 1. When the lifting component is engaged with the auxiliary mounting component 2, the external force for lifting can be reduced, which is conducive to the operator to quickly lift the solid hydrogen storage cylinder and improve the efficiency of the work.
[0044] The shape of the auxiliary installation component 2 in this application is not limited. It can be a ring, a triangle, or other shapes. As long as it can play the role of assisting in the installation of the lifting component, it is within the protection scope of this application.
[0045] In an embodiment where the first docking structure 12 and the second docking structure 13 are completely symmetrical and identical, the mounting hole 1231 is provided on both the first docking structure 12 and the second docking structure 13, and the auxiliary mounting component 2 is installed on both the first docking structure 12 and the second docking structure 13.
[0046] In summary, the handle 100 for solid hydrogen storage cylinders of this application is fixed to the neck of the solid hydrogen storage cylinder by the retaining ring 1 and is not related to the valve port of the solid hydrogen storage cylinder. During the process of lifting the solid hydrogen storage cylinder, it will not affect the valve port, thus avoiding the risk of valve port leakage. Moreover, the handle 100 of this application has a reasonable structural design, which improves the safety performance and structural strength during the process of lifting the solid hydrogen storage cylinder.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
