Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to an insulated hook mechanism and a lifting device. Background Technology

[0002] There are two types of traditional hooks: the first type is a single hook, which has a larger overall width and is suitable for hook positions with a relatively large gap; the second type is a double hook, in which the straight sections of the two hooks are connected in the middle by a metal rod to make them a whole, and the width of each hook is smaller, which is suitable for two independent and unconnected holes.

[0003] To ensure the overall structural strength and stability of the hook, both traditional hooks are generally made entirely of metal and have a large overall width. If they come into contact with two battery cell terminals of different polarities, a short circuit can easily occur. Therefore, metal hooks are not suitable for hooking and transporting electronic products such as batteries and battery cells.

[0004] In existing technologies, insulation of metal hooks is typically achieved by applying coatings such as baking paint, rubber coating, or Teflon plating to the surface to form an insulating layer. This allows the hooks to be used in electronic products, reducing the probability of short circuits. However, the insulating layer formed on the surface of the metal hook is often not durable and is prone to peeling off after repeated use. This peeling also produces debris, which, if it falls into the casing, is not only difficult to clean but also easily leads to defective products.

[0005] Therefore, researching a technology that can effectively insulate and prevent short circuits when hooking electronic products is of great significance for ensuring the quality and safety of electronic products. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides an insulated hook mechanism, which is composed of a load-bearing shaft, a hook assembly, and an insulating plate assembly. This mechanism can not only meet the needs of hooking multiple products and improve the overall working efficiency of the mechanism, but also the design of the insulating plate assembly can effectively ensure the insulation between different hooks within the hook assembly. Even if different hooks touch the battery terminals of different polarities, a circuit will not be formed, effectively ensuring the safety and quality when hooking electronic products.

[0007] This utility model also provides a lifting device, which is composed of a boom, a boom connecting ring and the above-mentioned insulated hook mechanism. It not only has good insulation performance, which can effectively ensure the safety and quality when hooking electronic products, but also has multiple insulated hook mechanisms set on one boom at the same time, which effectively improves the overall working efficiency of the lifting device.

[0008] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0027] As a preferred embodiment, when the bearing shaft is a metal bearing shaft, the insulating hook mechanism further includes an insulating bushing disposed between the bearing shaft and the hook assembly to ensure the insulation between the bearing shaft and the hook assembly.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0051] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0052] Example 1:

[0053] Please see the appendix Figure 1 The insulated hook mechanism 10 of this utility model embodiment includes a support shaft 100, a hook assembly 200 disposed on the support shaft 100, and an insulating plate assembly 300 connected to the support shaft 100 and disposed on the hook assembly 200. The support shaft 100 is used to realize the installation and connection of the entire mechanism; in use, only the support shaft 100 needs to be connected to the boom to achieve the connection of the entire mechanism. The hook assembly 200 is used to hook multiple products. The insulating plate assembly 300 is used to limit the movement of the hook assembly 200, and to achieve insulation and linkage between different hooks within the hook assembly 200.

[0054] The insulating hook mechanism 10 of this embodiment is formed by combining a bearing shaft 100, a hook assembly 200, and an insulating plate assembly 300. It can not only meet the hooking of multiple products and improve the overall working efficiency of the mechanism, but also the design of the insulating plate assembly 300 can effectively ensure the insulation between different hooks in the hook assembly 200. Even if different hooks touch the battery cell terminals of different polarities, no circuit will be formed, which effectively ensures the safety and quality when hooking electronic products.

[0055] In terms of material, the load-bearing shaft 100 is preferably a acetal steel load-bearing shaft or a metal load-bearing shaft. Both acetal steel and metal materials have good wear resistance, corrosion resistance, and structural strength, which can effectively ensure the overall stability and safety of the mechanism. Moreover, acetal steel has good insulation properties, which can further improve the overall insulation of the mechanism, thereby further ensuring the safety and quality of the mechanism in hooking electronic products. In terms of structure, the load-bearing shaft 100 is preferably a round shaft, square shaft, or prismatic shaft structure, which can be selected and designed according to actual needs. A round shaft structure is preferred because it is simple to process, and when the matching hook assembly 200 is installed on it, it can rotate freely around the axial direction of the round shaft, which is convenient for hooking products.

[0056] Furthermore, when the bearing shaft 100 is a metal bearing shaft, the insulated hook mechanism 10 also includes an insulated bushing 400 disposed between the bearing shaft 100 and the hook assembly 200. The insulated bushing 400 can effectively isolate the contact between the bearing shaft 100 and the hook assembly 200 to ensure the insulation between the bearing shaft 100 and the hook assembly 200, thereby effectively ensuring the overall insulation of the mechanism. Please refer to the appendix for further details. Figure 5The insulating bushing 400 includes a bushing portion 410 that passes between the load-bearing shaft 100 and the hook assembly 200 to separate the load-bearing shaft 100 and the hook assembly 200, and a limiting protrusion 420 provided on one end of the bushing portion 410 to prevent the hook assembly 200 from passing through.

[0057] Please refer to the appendix for further details. Figure 2 In some embodiments, the hook assembly 200 includes a first hook 210 and a second hook 220 symmetrically disposed at both ends of the load-bearing shaft 100 for hooking products. To ensure the overall structural strength and stability of the mechanism, preferably, both the first hook 210 and the second hook 220 are metal hooks.

[0058] Please refer to the appendix for further details. Figure 3 Both the first hook 210 and the second hook 220 include a hook mounting part 201 that passes through the support shaft 100 for overall hook installation and positioning, and a hook hooking part 202 provided on the hook mounting part 201 for product hooking. Preferably, the hook mounting part 201 is an annular mounting part adapted to the support shaft 100, which can move freely along the axial direction of the support shaft 100 when the insulation plate assembly 300 is not installed, so as to facilitate the overall installation of the hook. More preferably, the hook-taking part 202 is a "J"-shaped hook-taking part structure, and the width of the hook-taking part 202 perpendicular to its "J"-shaped cross-section does not exceed 20% of the length of the bearing shaft 100; that is, when the first hook 210 and the second hook 220 hook the product, the contact width with the product does not exceed 20% of the length of the bearing shaft 100. Compared with the single hook with a large overall width in the prior art, the area of ​​the first hook 210 and the second hook 220 exposed outside the insulating plate assembly 300 is small, and there will be no situation where a single hook touches two different polarity battery cell terminals at the same time, which further effectively ensures the safety and quality of the mechanism when hooking electronic products.

[0059] In some embodiments, the hook assembly 200 further includes a third hook disposed in the middle of the bearing shaft 100 for hooking the product, so as to further improve the overall working efficiency of the mechanism. Furthermore, the number of the third hook can be designed as one or more according to actual needs, and its structure is the same as that of the first hook 210 and the second hook 220, so it will not be described in detail here.

[0060] Please refer to the appendix for further details. Figure 2In some embodiments, the insulating plate assembly 300 includes a first insulating plate 310 and a second insulating plate 320 disposed opposite to each other on the load-bearing shaft 100 and the hook assembly 200, and an insulating plate connector disposed between the first insulating plate 310 and the second insulating plate 320. The first insulating plate 310 and the second insulating plate 320 are used to limit the positioning of the hook assembly 200 and to provide insulation between different hooks within the hook assembly 200; the insulating plate connector is used to connect the first insulating plate 310 and the second insulating plate 320 into a single unit, preferably, the insulating plate connector is a threaded connector.

[0061] Please refer to the appendix for further details. Figure 4 The first insulating plate 310 and the second insulating plate 320 are both acetal steel insulating plates. Specifically, each includes an insulating plate body 301, a shaft connection portion 302 disposed on the top of the insulating plate body 301 for connection with the load-bearing shaft 100, and a hook limiting groove 303 disposed on the insulating plate body 301 for limiting the hook assembly 200. Preferably, the length of the insulating plate body 301 is the same as the length of the load-bearing shaft 100, and the width is at least 20% of the overall height of the hook-taking portion 202. When the two insulating plates are connected as one unit using an insulating plate connector, the overall structural strength of the mechanism can be effectively guaranteed to prevent breakage during product hooking. More preferably, the hook limiting groove 303 is a U-shaped groove structure or a rectangular groove structure, and the interval between two adjacent hook limiting grooves 303 is at least 20% of the length of the bearing shaft 100, so as to prevent the hooks set in the hook limiting groove 303 from contacting each other, causing the battery terminals of different polarities to form a circuit, and thus causing a short circuit, effectively ensuring the safety and quality when hooking electronic products.

[0062] Example 2:

[0063] Please see the appendix Figure 6 The lifting device of this utility model embodiment includes a boom 20 for supporting and moving the entire lifting device, a boom 20 connecting ring disposed at the top of the boom 20 for connecting the entire lifting device to the lifting device drive equipment, and a plurality of insulated hook mechanisms 10 disposed on the boom 20 as described in Embodiment 1 for hooking the product. Preferably, the insulated hook mechanisms 10 are symmetrically disposed at both ends of the boom 20 to effectively ensure the consistency and balance of the entire lifting device.

[0064] The lifting device in this embodiment is formed by combining the boom 20, the boom 20 connecting ring and the above-mentioned insulated hook mechanism 10. It not only has good insulation performance, which can effectively ensure the safety and quality when hooking electronic products, but also has multiple insulated hook mechanisms 10 set on one boom 20 at the same time, which effectively improves the overall working efficiency of the lifting device.
