Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal shell side fixing technology, and in particular to a metal shell side fixing device. Background Technology
[0002] With the rapid development of optical communication technology, optical modules are the core optoelectronic conversion components in data centers, 5G networks and various communication equipment. Their performance and reliability are of paramount importance. Optical modules are usually encased in a metal shell to provide electromagnetic shielding, mechanical protection and heat dissipation.
[0003] Existing side-mounting methods for metal casings have some shortcomings. Some mounting devices have complex structures, and the installation and disassembly process is cumbersome, consuming a lot of time and manpower, which affects work efficiency. Moreover, some mounting methods are not stable enough. Under long-term use or when subjected to external forces such as vibration and impact, they are prone to loosening or even falling off, which in turn affects the normal operation and service life of the optical module. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of existing fixing devices, such as complex structure, cumbersome installation and disassembly process, high time and labor costs, reduced work efficiency, and poor stability of some fixing methods, which are prone to loosening or even falling off under long-term use or when subjected to external forces such as vibration and impact. This utility model provides a metal shell side fixing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal shell side fixing device, comprising a first shell, a second shell provided on the outer surface of the first shell, a pull rod provided on the outer surface of the first shell, a connecting plate fixedly connected to the outer surface of the pull rod, a connecting rod fixedly connected to the outer surface of the connecting plate, a slider fixedly connected to the outer surface of the connecting plate, a locking block fixedly connected to the outer surface of the slider, a sliding rod fixedly connected to the outer surface of the locking block, a spring sleeved on the outer surface of the sliding rod, one end of the spring fixedly connected to the locking block, and the other end of the spring fixedly connected to the first shell.
[0006] In a preferred embodiment, a convex groove is formed on the outer surface of the first housing, and a fixing block is fitted onto the inner wall of the convex groove.
[0007] In a preferred embodiment, the outer surface of the fixing block is engaged with the inner wall of the convex groove.
[0008] In a preferred embodiment, the outer surface of the fixing block is provided with two locking holes.
[0009] In a preferred embodiment, the inner wall of the card hole is engaged with the outer surface of the card block.
[0010] In a preferred embodiment, the inner wall of the first outer shell is provided with a sliding groove, and a plurality of sliding grooves are provided, some of which are provided on the inner wall of the second outer shell.
[0011] In a preferred embodiment, both the first and second housings are provided with pull rods on their outer surfaces.
[0012] In a preferred embodiment, both the outer surfaces of the first and second outer shells are provided with convex grooves.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a combination of components such as a pull rod, connecting plate, connecting rod, slider, locking block, sliding rod, and spring to effectively fix the side of a metal casing. When fixing is required, pulling the pull rod moves the connecting plate, causing the slider on the connecting plate to slide along the groove. Simultaneously, the locking block slides on the sliding rod and compresses the spring, placing the fixing block into the convex groove. Releasing the pull rod allows the spring to return to its elastic deformation, pushing the locking block into the locking hole, thus completing the fixed connection between the first casing and the fixing block, thereby achieving stable fixation of the side of the metal casing. This fixing method has the advantage of simple operation; workers only need to pull and release the pull rod to complete the fixing and disassembly operations, greatly improving work efficiency. Moreover, the tight connection between the multiple components of the device effectively prevents the metal casing from loosening or shifting during use, ensuring the stability and safety of the metal casing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a metal shell side fixing device, including a first shell 1, a second shell 2 on the outer surface of the first shell 1, a pull rod 3 on the outer surface of the first shell 1, a connecting plate 5 fixedly connected to the outer surface of the pull rod 3, a connecting rod 4 fixedly connected to the outer surface of the connecting plate 5, a slider 6 fixedly connected to the outer surface of the connecting plate 5, a locking block 7 fixedly connected to the outer surface of the slider 6, a sliding rod 8 fixedly connected to the outer surface of the locking block 7, a spring 9 sleeved on the outer surface of the sliding rod 8, one end of the spring 9 fixedly connected to the locking block 7, and the other end of the spring 9 fixedly connected to the first shell 1. A sliding groove 13 is opened on the inner wall of the first shell 1, and multiple sliding grooves 13 are opened, some of which are opened on the inner wall of the second shell 2. Pull rods 3 are provided on the outer surfaces of both the first shell 1 and the second shell 2.
[0021] In this embodiment, the first outer shell 1 and the second outer shell 2 form a protective shell to protect the internal components. Pulling the pull rod 3 moves the connecting plate 5, which in turn moves the connecting rod 4, which in turn moves the slider 6, which in turn moves the locking block 7, causing the locking block 7 to move into the slide groove 13. The movement of the locking block 7 moves the slide rod 8, and while the locking block 7 is moving, it compresses the spring 9, putting the spring 9 in a compressed state. This separates the locking block 7 from the locking hole 12 in the fixing block 11, making it convenient for workers to disassemble the two outer shells.
[0022] Example 2 like Figures 1-4 As shown, a convex groove 10 is provided on the outer surface of the first outer shell 1. Both the outer surfaces of the first outer shell 1 and the second outer shell 2 are provided with convex grooves 10. A fixing block 11 is sleeved on the inner wall of the convex groove 10. The outer surface of the fixing block 11 is engaged with the inner wall of the convex groove 10. A locking hole 12 is provided on the outer surface of the fixing block 11. There are two locking holes 12. The inner wall of the locking hole 12 is engaged with the outer surface of the locking block 7.
[0023] In this embodiment, when it is necessary to assemble the two outer shells, the first outer shell 1 and the second outer shell 2 are aligned so that the convex grooves 10 opened on the two outer shells are aligned. Then, the fixing block 11 is slid into the inside of the convex groove 10, and the fixing block 11 presses the locking block 7, so that the locking block 7 presses the spring 9. When the locking hole 12 opened on the surface of the fixing block 11 is aligned with the locking block 7, the spring 9 rebounds and drives the locking block 7 to engage with the locking hole 12, thus completing the fixing of the fixing block 11. The fixing block 11 completes the fixing of the two outer shells, ensuring that the outer shells will not separate during operation.
[0024] Working principle: like Figures 1-4 As shown, in this invention, firstly, when in normal working condition, the spring 9 is in its natural state, and the locking block 7 is engaged in the locking hole 12 of the fixing block 11, so that the first outer shell 1 and the second outer shell 2 are firmly connected together by the fixing block 11. In this state, the entire device can stably protect the internal components and prevent external factors from damaging them.
[0025] When maintenance or replacement of internal components is required, the operator can pull the lever 3. Since the lever 3 is fixedly connected to the connecting plate 5, pulling the lever 3 will move the connecting plate 5. The movement of the connecting plate 5 will in turn move the connecting rod 4 and the slider 6 connected to it. Because the slider 6 is fixedly connected to the locking block 7, the locking block 7 will move together with the slider 6 in the slide groove 13. At the same time, the movement of the locking block 7 will move the sliding rod 8, and the locking block 7 will squeeze the spring 9, causing the spring 9 to gradually enter a compressed state. As the spring 9 is compressed, the locking block 7 will gradually disengage from the locking hole 12 of the fixing block 11. When the locking block 7 is completely disengaged from the locking hole 12, the first outer shell 1 and the second outer shell 2 can be easily separated, thus facilitating internal operations. After maintenance or replacement work is completed, the first outer shell 1 and the second outer shell 2 need to be reassembled. The operator first aligns the first outer shell 1 and the second outer shell 2 so that the convex grooves 10 on the two shells are aligned with each other. Then, the fixing block 11 slides along the inner wall of the convex groove 10 into the groove. During the sliding process, the fixing block 11 will squeeze the locking block 7, causing the locking block 7 to further compress the spring 9. When the fixing block 11 slides to the position where the locking hole 12 on its surface is aligned with the locking block 7, the compressed spring 9 will rebound due to its own elasticity, causing the locking block 7 to re-lock into the locking hole 12. In this way, the fixing block 11 is firmly fixed in the convex groove 10, thereby realizing the stable connection between the first outer shell 1 and the second outer shell 2, so that the entire device can work normally again.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
