Description

Technical Field

[0001] This invention relates to the field of snap hook technology, and in particular to a snap hook and its usage method, an unlocking device and its usage method, and an optical device. Background Technology

[0002] With the rapid development of optical communication, optical devices have also been widely used. Existing fiber optic connectors mainly consist of ferrules, connector bodies (connector shells), optical cables, and connection devices. The ferrules of a fiber optic connector are generally made of metal, ceramic, or plastic and serve as an alignment element during fiber connection. The connector body typically consists of multiple components, and the shell of the connector body is generally made of metal or plastic. The optical cable is the core point (input point) of the fiber optic connector and is installed on the connector body. Additionally, the joint between the optical cable and the connector body has a strain relief shield, providing extra strength to the joint. The connection device generally does not use a male and female connector structure; it typically employs a mating connector positioning sleeve.

[0003] Existing fiber optic connectors are typically assembled from multiple components, resulting in high manufacturing costs, complex installation processes, and a high risk of accumulating processing errors during assembly.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0005] The technical problem to be solved by this invention is how to solve the problem that existing fiber optic connectors are composed of multiple parts, which leads to high manufacturing costs, complex installation processes, and easy accumulation of processing errors during assembly.

[0006] The embodiments of the present invention adopt the following technical solutions:

[0007] In a first aspect, the present invention provides a hook for coupling an optical device, the optical device having an adapter ring, the adapter ring including a flat position and a snap-in position, and the hook including a hook body 1.

[0008] The hook body 1 is provided with an installation groove 11. The inner wall of the installation groove 11 is provided with a limiting groove 111 and an elastic fin 112. The elastic fin 112 is suspended from the bottom surface of the installation groove 11, and the upper surface of the elastic fin 112 is higher than the bottom surface of the limiting groove 111.

[0009] The elastic fin 112 is pressed by the snap-in position until the adapter ring and the limiting groove 111 are on the same plane, and the snap-in position is screwed into the limiting groove 111.

[0010] After the elastic fin 112 rebounds, the elastic fin 112 locks with the flat position.

[0011] Preferably, a relief groove 113 is provided on the bottom surface of the mounting groove 11. The relief groove 113 is disposed opposite to the elastic fin 112 so that the elastic fin 112 is pressed into the relief groove 113 by force, so that the adapter ring is located in the plane of the limiting groove 111, so that the adapter ring can be rotated into the limiting groove 111 and fixed.

[0012] Preferably, the bottom surface of the limiting groove 111 is higher than the bottom surface of the mounting groove 11, the elastic fin 112 is flush with the limiting groove 111, and the elastic fin 112 is pressed by force to abut against the bottom surface of the mounting groove 11, so that the adapter ring is in the plane where the limiting groove 111 is located, so that it can be rotated into the limiting groove 111 and fixed.

[0013] Preferably, the hook further includes two hook arms 2, which are used to couple jumpers. One end of the hook arm 2 has a hook fastening point 21 on its inner side, and the other end of the hook arm 2 is connected to the end face of the hook body 1. Jumper fastening positions are provided on both sides of the jumper, and the hook fastening point 21 locks with the jumper fastening position to realize the coupling between the hook and the jumper.

[0014] Preferably, the hook body 1, hook arm 2 and elastic fin 112 are integrally formed.

[0015] Preferably, an arc-shaped surface 114 is provided on the inner wall of the mounting groove 11, and one side of the arc-shaped surface 114 is connected to the side of the limiting groove 111 so that the fitting ring can be inserted into the limiting groove 111 through the arc-shaped surface 114.

[0016] Secondly, the present invention also provides a method for using a snap hook, the method being applicable to the coupling of the snap hook described in the first aspect with the optical device, the method of using the snap hook comprising:

[0017] Insert the optical device into the mounting groove 11 of the hook body 1, and press the elastic fin 112 by the snap-fit ​​on the adapter ring of the optical device so that the adapter ring of the optical device and the limiting groove 111 are in the same plane.

[0018] While keeping the elastic fin 112 in a compressed state, rotate the optical device so that the snap-in position on the adapter ring moves into the limiting groove 111, so that the flat position rotates to be opposite to the elastic fin 112, so that the elastic fin 112 can spring back to lock with the flat position.

[0019] Thirdly, the present invention also provides an optical device having an adapter ring that matches a limiting groove 111 on a hook in the first aspect, so that the optical device is coupled to the hook.

[0020] Fourthly, the present invention also provides an unlocking device, which is applied to the hook described in the first aspect to unlock the optical device from the hook. The unlocking device includes a gripping part and two disassembly hooks.

[0021] Two disassembly hooks are disposed opposite each other on both sides of one end of the unlocking device. Each disassembly hook includes a hook tip, which is disposed at the end of the disassembly hook and is positioned towards the inside of the disassembly hook so that the hook tip is inserted directly above the latch, so as to unlock the device by pressing the elastic fin 112 with the hook tip.

[0022] Fifthly, the present invention also provides a method of using the unlocking device, the method being applicable to the unlocking device described in the fourth aspect, for unlocking the hook and the optical device, the method comprising:

[0023] Insert the disassembly hook of the unlocking device into the mounting groove 11 of the latch, so that the hook tip 521 of the disassembly hook abuts against the elastic fin 112;

[0024] Pulling the unlocking device causes the hook tip 521 to press the elastic fin 112, which moves toward the bottom surface of the mounting groove 11 to release the locking state between the elastic fin 112 and the flat part.

[0025] While keeping the elastic fin 112 in a compressed state, rotate the optical device so that the locking position of the optical device is rotated out of the limiting groove 111 until the locking position is directly above the elastic fin 112. Then pull out the optical device to complete the disassembly of the hook.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] The snap-fit ​​structure provided by this invention includes an elastic fin 112 and a limiting groove 111. The elastic fin 112 is suspended from the bottom surface of the mounting groove 11. An adapter ring is provided on the optical device, including a flat position and a snap-fit ​​position. The optical device is inserted into the mounting groove 111 of the snap-fit ​​hook, and the snap-fit ​​position compresses the elastic fin 112 until the adapter ring and the limiting groove 111 are on the same plane. Then, the optical device is rotated so that the snap-fit ​​position of the adapter ring rotates into the limiting groove 111. After the elastic fin 112 springs back, it locks with the flat position. The snap-fit ​​structure provided by this invention is simple and can be quickly molded, with a simple manufacturing process and low cost. In use, only "insertion and rotation" are needed to complete the installation of the optical device and the snap-fit ​​hook, which is simple and convenient, with high assembly efficiency and stable connection. It is used in pairs with optical devices and is widely used in terminal equipment such as optical modems and optical switches, which are important components of optical networks. There is a large market demand, and it has great application value. Attached Figure Description

[0047] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the term "coupled" can refer to an electrical connection that enables signal transmission.

[0048] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1:

[0050] Embodiment 1 of the present invention provides a hook, such as Figures 1-3 As shown, the hook is used to couple the optical device 3. The optical device 3 is provided with an adapter ring 31. The adapter ring 31 includes a flat position 311 and a snap-in position 312. The hook includes a hook body 1.

[0051] like Figures 4-5 As shown, the hook body 1 is provided with a mounting groove 11. The inner wall of the mounting groove 11 is provided with a limiting groove 111 and an elastic fin 112. The axial direction of the extending limiting groove 111 is perpendicular to the axial direction of the elastic fin 112. The elastic fin 112 is suspended from the bottom surface of the mounting groove 11. The upper surface of the elastic fin 112 is higher than the bottom surface of the limiting groove 111.

[0052] The elastic fin 112 is pressed by the locking position 312 until the adapter ring and the limiting groove 111 are on the same plane (see reference). Figure 5 As shown), the locking position 312 is screwed into the limiting groove 111; after the elastic fin 112 rebounds, the elastic fin 112 locks with the flat position 311.

[0053] like Figure 1The hook of this embodiment of the invention is used to couple an optical device 3 with an adapter ring 31. The optical device 3 adapted to the hook of this embodiment of the invention is provided with an adapter ring 31, which includes a flat part 311 and a snap-in part 312. The hook of this embodiment of the invention includes a hook body 1, on which a mounting groove 11 is provided, and an elastic fin 112 is provided in the mounting groove 11, and the elastic fin 112 is suspended. In the initial position (when the elastic fin 112 is not compressed), the elastic fin 112 is higher than the bottom surface of the limiting groove 111. When the optical device 3 is inserted into the corresponding mounting groove 11, the elastic fin 112 is compressed by the locking position 312, causing the elastic fin 112 to move along the direction close to the bottom surface of the mounting groove 11. When the upper surface of the elastic fin 112 is compressed to no higher than the bottom surface of the limiting groove 111 (it should be noted that one end of the elastic fin 112 is connected to the mounting groove 11, and the other end of the elastic fin 112 is the movable end; here, it mainly refers to the movable end of the elastic fin 112 not being higher than the bottom surface of the limiting groove 111), At this time, the plane where the adapter ring 31 is located is flush with the plane where the limiting groove 111 is located (the adapter ring 31 and the limiting groove 111 are on the same plane). Rotate the optical device 3 so that the snap-in position 312 on the adapter ring 31 rotates into the limiting groove 111 of the hook body 1, thereby causing the flat position 311 on the adapter ring 31 to rotate to be opposite to the elastic fin 112, thereby causing the elastic fin 112 to lose the compression of the snap-in position 312, and causing the elastic fin 112 to spring back to its initial state, so that the end face of the elastic fin 112 locks with the flat position 311 of the adapter ring 31, thereby fixing the optical device 3 in the hook body 1.

[0054] It is worth noting that, in the initial state (before compression), the end face of the elastic fin 112 in this embodiment of the invention is typically flush with the position of the limiting groove 111, so that after the elastic fin 112 rebounds, it can lock with the flat part 311 on the adapter ring 31 provided in the limiting groove 111. The flat part 311 on the adapter ring 31 in this embodiment of the invention can be understood as being formed by cutting the disc-shaped adapter ring 31 on both sides. When the flat part 311 on the adapter ring 31 rotates to align with the elastic fin 112, the elastic fin 112... The elastic fin 112 locks against the flat portion 311 after the compression rebounds. Theoretically, this embodiment of the invention only requires one flat portion 311 and one elastic fin 112 corresponding to the flat portion 311 to lock the adapter ring 31. However, considering the stress conditions during use, to avoid the invention having only one elastic fin 112 causing single-point stress and making it more prone to damage, this embodiment of the invention, in actual production, usually places the adapter ring 31 on both sides (opposite side direction, see...) Figure 1 or Figure 5As shown in the figure (not marked), the part is processed into a flat position, and an elastic fin 112 is respectively provided on the opposite side of the corresponding hook body 1 to avoid the problem of damage to the elastic fin 112 caused by single-point force. In addition, in order to facilitate the insertion of the optical device 3 into the hook body 1, the bottom surface of the hook body 1 of this embodiment is provided with a first mounting hole penetrating the hook body 1, so that the front end of the adapter ring 31 of the optical device 3 is inserted into the hook body 1 through the first mounting hole, and then the elastic fin 112 is squeezed by the snap-in position 312 of the adapter ring 31. When the adapter ring 31 and the limiting groove 111 are in the same plane, the optical device 3 is rotated to rotate the snap-in position 312 of the adapter ring 31 into the limiting groove 111.

[0055] The hook structure provided by this invention is simple and can be quickly manufactured using molds, resulting in a simple manufacturing process and low cost. Installation of the optical device 3 and the hook requires only "insertion and rotation," making it simple, convenient, efficient, and stable. Used in pairs with the optical device 3, it is widely applied in terminal equipment such as optical modems and optical switches, which are important components of optical networks, and has significant market demand and application value.

[0056] To illustrate the complete solution of the embodiments of the present invention, the details of the embodiments of the present invention will be described in detail below. In order to achieve locking of the optical device 3 by means of the elastic fin 112, the initial state of the elastic fin 112 in the embodiments of the present invention needs to be set to be flush with the limiting groove 111 (see Figure 6 As shown, this allows the elastic fin 112 to be locked to the flat portion 311 of the adapter ring 31 after it rebounds. Based on this, the hook body 1 of this embodiment of the invention has at least two structural configurations to achieve the locking of the elastic fin 112 to the flat portion 311 of the adapter ring 31.

[0057] The first method, such as Figure 1 and Figure 7 As shown, a clearance groove 113 is provided on the bottom surface of the mounting groove 11. The clearance groove 113 is disposed opposite to the elastic fin 112 so that the elastic fin 112 is pressed into the clearance groove 113 by force, so that the adapter ring 31 is located in the plane of the limiting groove 111, so that the adapter ring 31 can be rotated into the limiting groove 111 and fixed.

[0058] In the first method, a clearance groove 113 is provided on the bottom surface of the mounting groove 11. The clearance groove 113 is arranged opposite to the elastic fin 112. When the elastic fin 112 is squeezed, the elastic fin 112 will move along the direction of the bottom surface of the mounting groove 11. The clearance groove 113 mainly serves to increase the squeezing stroke of the elastic fin 112, so that after the elastic fin 112 is squeezed, the upper surface of the elastic fin 112 is not higher than the bottom surface of the limiting groove 111. Thus, the adapter ring 31 and the limiting groove 111 are in the same plane. Rotating the optical device 3 causes the locking position 312 on the adapter ring 31 to rotate into the limiting groove 111. The corresponding flat position 311 rotates to be opposite to the elastic fin 112, causing the elastic fin 112 to spring back and be locked by the elastic fin 112 and the flat position 311.

[0059] In the second method, the bottom surface of the limiting groove 111 is higher than the bottom surface of the mounting groove 11, and the elastic fin 112 is flush with the limiting groove 111. The elastic fin 112 is pressed by force to abut against the bottom surface of the mounting groove 11, so that the adapter ring 31 is in the plane where the limiting groove 111 is located, so that the adapter ring 31 can be rotated into the limiting groove 111 and fixed.

[0060] To achieve coupling and fixation between the hook and the optical device 3 using the elastic fin 112 and limiting groove 111 on the hook in this embodiment of the invention, as well as the snap-in position 312 and flat position 311 on the adapter ring 31, this embodiment of the invention requires that the initial state of the elastic fin 112 (the elastic fin 112 is not compressed) be kept flush with the limiting groove 111. Furthermore, after the elastic fin 112 is compressed, it should be compressed so that its upper surface is not higher than the bottom surface of the limiting groove 111, thereby allowing the snap-in position 312 on the adapter ring 31 to rotate into the limiting groove 111. Therefore, in the second implementation of the present invention, the corresponding clearance groove 113 may not be provided. By raising the position of the limiting groove 111, the bottom surface of the second limiting groove 111 is higher than the bottom surface of the mounting groove 11. In addition, the end face of the elastic fin 112 in its initial state (the elastic fin 112 is not compressed) is always kept flush with the position of the limiting groove 111. When the elastic fin 112 is compressed, due to the restriction of the bottom surface of the mounting groove 11, the elastic fin 112 abuts against the bottom surface of the mounting groove 11 when the elastic fin 112 has its maximum stroke. It is only necessary to ensure that when the elastic fin 112 abuts against the mounting groove 11, the upper surface of the elastic fin 112 is higher than the bottom surface of the limiting groove 111 to satisfy the purpose of the present invention to transfer the snap-in position 312 on the adapter ring 31 into the limiting groove 111. It is worth noting that, in the embodiments of the present invention, it is only necessary to appropriately adjust the height of the bottom surface of the limiting groove 111 and the specific mounting groove 11 of the elastic fin 112 to ensure that when the elastic fin 112 abuts against the mounting groove 11, the upper surface of the elastic fin 112 is higher than the bottom surface of the limiting groove 111, thereby ensuring the feasibility of the second method of the embodiments of the present invention.

[0061] In order to ensure that the snap-in position 312 on the adapter ring 31 of the optical device 3 in this embodiment of the invention can be smoothly rotated into the limiting groove 111 of the snap hook body 1, such as Figure 7 As shown, in this embodiment of the invention, the inner wall of the mounting groove 11 is provided with an arc-shaped surface 114. One side of the arc-shaped surface 114 is connected to the side of the limiting groove 111, so that the snap-in position 312 of the adapter ring 31 can rotate into the limiting groove 111 through the arc-shaped surface 114. In this embodiment of the invention, by setting the part of the inner wall of the mounting groove 11 that abuts against the adapter ring 31 as an arc-shaped surface 114, and connecting one side of the arc-shaped surface 114 to the side of the limiting groove 111, the snap-in position 312 of the adapter ring 31 can smoothly rotate into the limiting groove 111 along the arc-shaped surface 114. It is worth noting that, for the embodiments of the invention... Figures 5-7 ,as well as Figure 13 In order to clearly see the connection between the corresponding structure and the internal structure of the hook, Figures 5-7 ,as well as Figure 13 In the process, some structures on the hook body 1 were cut; however, in actual installation, the shape of the corresponding hook was not actually cut. This is understandable. Figures 5-7 ,as well as Figure 13 This presentation is for ease of understanding at least; in reality, the structure of the hook can be understood as, for example... Figure 4 The structural shape.

[0062] In addition, this embodiment of the invention is also used in another application scenario, where the structure within the latch of this embodiment is used to connect the optical device 3 to the external jumper 4. To utilize the latch of this embodiment to connect the optical device 3 to the jumper 4, as follows... Figure 7 and Figure 8 As shown, the hook in this embodiment of the invention further includes two hook arms 2. The hook arms 2 are used to couple the jumper wire 4. A hook fastening point 21 is provided on the inner side of one end of the hook arm 2. The end face of the other end of the hook arm 2 is connected to the end face of the hook body 1. Jumper wire fastening positions 41 are provided on both sides of the jumper wire 4. The hook fastening point 21 is locked with the jumper wire fastening position 41 to realize the coupling between the hook and the jumper wire 4.

[0063] like Figures 7-9 As shown, the hook of this embodiment includes a hook body 1 and two hook arms 2. The end face of the other end of the hook arm 2 is connected to the end face of the hook body 1 to form a complete hook of this embodiment. A hook snap point 21 is provided on the inner side of one end of the hook arm 2, and jumper wire snap positions 41 are provided on both sides of the corresponding jumper wire 4. The hook is inserted into the jumper wire snap position 41 of the jumper wire 4 through the hook arm 2, and locked by the hook snap point 21 and the jumper wire snap position 41 to realize the coupling between the hook and the jumper wire 4. It is worth noting that when coupling the hook and jumper 4 in this embodiment of the invention, corresponding jumper fasteners 41 need to be set on both sides of the jumper 4 in advance, and the jumper fasteners 41 need to match the hook fasteners 21 on the hook so that the hook fasteners 21 can lock with the jumper fasteners 41, thereby achieving coupling between the hook and the jumper 4. In this embodiment of the invention, the hook body 1 and hook arm 2 on the hook can achieve coupling connection between the optical device 3 and the jumper 4, and fix them together by the hook.

[0064] In addition, in a preferred application scenario, the hook body 1, hook arm 2 and elastic fin 112 described in this embodiment of the invention are integrally formed.

[0065] The hook structure provided by this invention is simple and can be quickly manufactured using molds, resulting in a simple manufacturing process and low cost. During use, installation of the optical device 3 and the hook requires only "insertion and rotation," making it simple, convenient, efficient in assembly, and stable in connection. Used in pairs with the optical device 3, it is widely applied in terminal equipment such as optical modems and optical switches, which are important components of optical networks, and has significant market demand and application value. In addition, the hook of this invention also includes a hook arm 2, which is provided with hook locking points 21. By providing jumper clips 41 on both sides of the jumper cable 4, the hook locking points 21 can lock with the jumper clips 41, thereby achieving coupling between the hook and the jumper cable 4. Through the action of the hook, the optical device 3 and the jumper cable 4 are coupled together.

[0066] Example 2:

[0067] Embodiment 2 of the present invention also provides a method for using the hook, the method being applicable to the coupling of the hook described in Embodiment 1 with the optical device 3, such as... Figure 10 As shown, the method of using the hook includes:

[0068] Step 201: Insert the optical device 3 into the mounting groove 11 of the hook body 1. The elastic fin 112 is pressed by the snap-fit ​​position 312 on the adapter ring 31 of the optical device 3, so that the adapter ring 31 of the optical device 3 and the limiting groove 111 are in the same plane. In this embodiment, the hook is mainly used for coupling the optical device 3. During the coupling process between the optical device 3 and the hook, this embodiment only requires inserting the adapter ring 31 of the optical device 3 into the mounting groove 111 of the hook body 1. The snap-fit ​​position 312 of the adapter ring 31 presses the elastic fin 112, ensuring that the upper surface of the elastic fin 112 is not higher than the bottom surface of the limiting groove 111, thereby making the plane of the adapter ring 31 flush with the plane of the limiting groove 111. In the process of inserting the optical device 3 into the mounting groove 11 in the embodiment of the present invention, the snap-in position 312 of the adapter ring 31 of the optical device 3 is first aligned with the elastic fin 112 so that when the adapter ring 31 is inserted along the mounting groove 11, the elastic fin 112 in the snap-in position 312 can be squeezed by the snap-in position 312.

[0069] Step 202: Keep the elastic fin 112 in a compressed state, rotate the optical device 3 so that the snap-in position 312 on the adapter ring 31 rotates into the limiting groove 111, so that the flat position 311 rotates to be opposite to the elastic fin 112, so that the elastic fin 112 can spring back to lock with the flat position 311.

[0070] After the plane of the adapter ring 31 is flush with the plane of the limiting groove 111, keep the elastic fin 112 in a compressed state and rotate the optical device 3 so that the snap-in position 312 on the adapter ring 31 is rotated into the limiting groove 111; after the snap-in position 312 of the adapter ring 31 is rotated into the limiting groove 111, the flat position 311 is rotated to align with the elastic fin 112, and the elastic fin 112 rebounds, so that the elastic fin 112 and the flat position 311 on the adapter ring 31 are locked.

[0071] After the hook body 1 is locked to the adapter ring 31 of the optical device 3, the method of using the hook in this embodiment of the invention also includes the connection between the hook and the jumper 4, specifically including: inserting the hook arm 2 of the hook into the jumper buckle position 41 of the jumper 4 through the hook buckle point 21 to lock it, thereby realizing the connection between the hook and the jumper 4.

[0072] The hook structure provided by this invention is simple and can be quickly manufactured using a mold, resulting in a simple manufacturing process and low cost. During use, installation of the optical device 3 and the hook requires only "insertion and rotation," making it simple, convenient, efficient, and stable in connection. The connection between the hook and the jumper cable 4 is achieved by simply inserting the hook arm 2 into the jumper cable latches 41 on both sides of the jumper cable 4, thus locking the hook and jumper cable 4 together and coupling the optical device 3 and the jumper cable 4.

[0073] Example 3:

[0074] Embodiment 3 of the present invention also proposes an optical device 3, which is provided with an adapter ring 31. The adapter ring 31 matches the limiting groove 111 on the hook described in Embodiment 1, so that the optical device 3 is coupled to the hook.

[0075] The structure of the optical device 3 with the adapter ring 31 has been described in Embodiment 1 of the present invention, and will not be repeated here.

[0076] Example 4:

[0077] Embodiment 4 of the present invention also provides an unlocking device and a method for using the unlocking device 5. For example... Figures 11-13 As shown, the unlocking device 5 is applied to the hook described in Embodiment 1 to unlock the optical device 3 from the hook. The unlocking device 5 includes a gripping part 51 and two disassembly hooks 52.

[0078] Two disassembly hooks 52 are disposed opposite to each other on both sides of one end of the unlocking device 5. Each disassembly hook 52 includes a hook tip 521, which is disposed at the end of the disassembly hook 52. The hook tip 521 is disposed inward of the disassembly hook 52 so that it is inserted directly above the latch, so as to unlock the elastic fin 112 by pressing the hook tip 521.

[0079] The unlocking device 5 of this embodiment includes a gripping part 51 and two disassembly hooks 52. The two disassembly hooks 52 are arranged opposite each other on both sides of one end of the unlocking device 5, making the unlocking device 5 as a fork-shaped part. The disassembly hooks 52 include hook tips 521, which are arranged inside the disassembly hooks 52. By inserting the hook tips 521 into the mounting groove 11 directly above the elastic fin 112, the elastic fin 112 is squeezed by the hook tips 521. When the upper surface of the elastic fin 112 is squeezed to be higher than the bottom surface of the limiting groove 111, the optical device 3 is rotated so that the locking position 312 on the adapter ring 31 rotates out of the limiting groove 111, thereby realizing the unlocking between the optical device 3 and the hook. It is worth noting that if the hook, optical device 3, and jumper 4 are connected before using the unlocking device 5 to unlock the hook and optical device 3, the hook arm 2 must first be pried open to separate it from the jumper 4 before the unlocking device 5 can be used to disassemble the hook and optical device 3. Therefore, in actual production, the hook arm 2 has a certain degree of flexibility, allowing it to engage with the jumper clips 41 on both sides of the jumper 4. When unlocking is required, the hook arm 2, with its flexibility, can be disengaged from the jumper clips 41 by applying force, thus completing the disassembly of the hook arm 2 from the jumper 4.

[0080] In addition, based on the unlocking device 5 of this embodiment, this embodiment also includes a method of using the unlocking device 5 to disassemble the hook and the optical device 3. The method of using the unlocking device includes: inserting the disassembly hook 52 of the unlocking device 5 into the mounting groove 11 of the hook, so that the hook tip 521 of the disassembly hook 52 abuts against the elastic fin 112; pulling the unlocking device, the hook tip 521 presses the elastic fin 112, and the elastic fin 112 moves towards the bottom surface of the mounting groove 11 to release the locking state between the elastic fin 112 and the flat position 311; keeping the elastic fin 112 in the pressed state, rotating the optical device 3, so that the locking position 312 of the optical device 3 rotates out of the limiting groove 111 until the locking position 312 is directly above the elastic fin 112, and pulling out the optical device 3 to complete the disassembly of the hook.

[0081] The process of disassembling the hook and the optical device 3 through the disassembly device in this embodiment of the invention has been described above and will not be repeated here.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
