Description

Technical Field

[0001] This utility model relates to the field of optical module technology, specifically to a springless rear-mounted pull ring module. Background Technology

[0002] Traditional optical modules, due to structural limitations, have the following assembly process: the engine is first installed into the base of the structural component, then a pull ring is attached to the base, and finally, the top cover is locked to the base with screws. The top cover, in conjunction with the base, secures the pull ring. To unlock, the pull ring is pulled, causing the unlocking arm within it to move backward. The unlocking point on the unlocking arm then unlocks the unlocking spring on the cage. During this process, a spring located between the unlocking arm and the structural component is compressed. When the external force is released, the spring returns to its original state, thus resetting the unlocking arm. Subsequent performance testing of the optical modules is conducted. For optical modules that pass the test, production is theoretically complete. However, some customers require the installation of pull rings of different colors or markings, resulting in rework of the optical modules. During rework, since the pull rings cannot be directly removed from the structural components, the top cover must be disassembled, the pull rings removed, and then the pull rings of the corresponding colors or markings replaced. The top cover and base must then be re-locked with screws. After this operation, since the top cover has been reopened, the optical modules must be retested, which affects production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a springless rear-mounted pull ring module to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A springless rear-mounted pull ring module includes: a structural component and a pull ring with a handle. On both sides of the structural component, from the middle region to the tail end face, slide grooves matching the unlocking arms in the pull ring are respectively formed. Each unlocking arm has a limiting block inclined from the inside out near its unlocking point. Each slide groove has a travel groove that limits the travel of the limiting block. The two unlocking arms of the pull ring are respectively located in the two slide grooves on the structural component, and the limiting blocks on each unlocking arm are respectively located in the travel grooves on the same side. On the bottom surface of the base in the structural component, a groove is formed at the base plate corresponding to the two unlocking arms in the pull ring. The base plate has a spring piece inclined from front to back and entering the groove.

[0005] The beneficial effects of this utility model are: When installing the pull ring, position the two unlocking arms on either side of the structural component and align them with the two slide grooves. Then, push the pull ring forward. When the limit blocks on the two unlocking arms align with the travel grooves, press the limit blocks inward to deform them and allow them to enter the travel grooves. Simultaneously, the unlocking arms also enter the slide grooves. After the limit blocks enter the travel grooves, they automatically return to their original state. Continue pushing the pull ring forward; the limit blocks can move within the travel grooves. At the same time, the spring clip enters the groove. This completes the installation of the pull ring. The structural component does not need to be disassembled during this process. To unlock the pull ring against the unlocking spring clip on the cage later, pull the pull ring backward. The unlocking point moves backward to unlock with the unlocking spring on the cage. During the backward pulling of the ring, the spring can press against the bottom of the groove and deform. When the external force is released, the spring will reset the unlocking arm as it returns to its original state. By designing the spring on the ring and the groove on the structural component, the cooperation of the two can replace the spring, thus achieving spring-free operation. The module can first complete the assembly of the structural component and the engine, and then carry out the preliminary testing process. Afterward, different colored or marked rings can be installed, so as not to affect the already assembled structural component and engine, and also to avoid retesting.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the connection between the limiting block and the unlocking arm is a smooth arc shape.

[0008] The further beneficial effect of adopting the above is that when the limiting block is pressed into the stroke groove with force, the smooth arc shape helps the limiting block to be pressed into the stroke groove.

[0009] Furthermore, each unlocking arm has a limiting block that tilts outward from the inside and is located above and below its unlocking point. Each slide groove has a travel groove at the bottom and top. The two limiting blocks on each unlocking arm are located in the two travel grooves on the same side.

[0010] Furthermore, a notch is made on the bottom surface of the base in the structural component, which is connected to the travel groove.

[0011] Furthermore, part of the travel groove is located on the base of the structural component, while other areas are located on the top cover of the structural component.

[0012] Furthermore, on the end face of the tail end of the structural component, a limiting groove is opened at each corresponding slide groove, which is distributed along its length and communicates with the slide groove. Each unlocking arm in the slide groove is provided with a limiting piece that enters the limiting groove, and the connection between the limiting piece and the unlocking arm is bent inward.

[0013] Furthermore, the limiting groove is located on the upper cover of the structural component.

[0014] Furthermore, a first through groove and a second through groove that are not interconnected are formed on the substrate in the area where the spring piece is located, and an arc-shaped strip connected to the spring piece is formed on the substrate in the area between the first through groove and the second through groove.

[0015] The further beneficial effects of adopting the above are: the arc-shaped strip is used to increase the elasticity and deformation of the spring.

[0016] Furthermore, the shrapnel is located in the middle area of ​​the curved strip. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Example 1 like Figures 1 to 8 As shown, a springless, rear-mounted pull ring module includes: The structural component 1 and the pull ring 2 with a handle 210 are provided. A slide groove 110 is formed on each of the two sides of the structural component 1, and the slide groove 110 on each side extends from the middle area of ​​the side of the structural component 1 to its tail end face, i.e., it penetrates the tail end face of the structural component 1. Each slide groove 110 is used to match the unlocking arm 220 in the pull ring 2. Each unlocking arm 220 is provided with a limiting block 222 that tilts from the inside out, and the limiting block 222 on each unlocking arm 220 is adjacent to the unlocking point 2 of that unlocking arm 220. 21. Each slide groove 110 has a stroke groove 120, and the two unlocking arms 220 of the pull ring 2 are respectively located in the two slide grooves 110 on the structural component 1. The limiting block 222 on each unlocking arm 220 is located in the stroke groove 120 on the same side as it (limiting block 222). The stroke groove 120 is used to limit the stroke of the limiting block 222. The stroke must meet the requirement that when the pull ring 2 is pulled, the unlocking point 221 on the unlocking arm 220 can unlock the module and the unlocking spring on the cage. On the bottom surface of the base 130 in structural component 1, a groove 131 is formed at the base plate 230 that is connected to the two unlocking arms 220 in the corresponding pull ring 2. The pull ring 2 consists of a handle 210, a base plate 230 and two unlocking arms 220. The handle 210 is connected to the base plate 230, and the two unlocking arms 220 are also connected to the base plate 230. The two unlocking arms 220 and the base plate 230 are integrally formed. The base plate 230 is provided with a spring piece 231 that is inclined from front to back and enters the groove 131.

[0021] When installing pull ring 2, position the two unlocking arms 220 of pull ring 2 on both sides of structural component 1 and align them with the two slide grooves 110. Then push pull ring 2 forward. When the limiting blocks 222 on the two unlocking arms 220 align with the travel groove 120, press the limiting blocks 222 inward to deform them and enter the travel groove 120. At the same time, the unlocking arms 220 also enter the slide groove 110. After the limiting blocks 222 enter the travel groove 120, they automatically return to their original state. Continue pushing pull ring 2 forward, and the limiting blocks 222 can move within the travel groove 120. Simultaneously, the spring piece 231 enters the groove 131. This completes the installation of pull ring 2. Structural component 1 does not need to be disassembled during this process. The pull ring 2 is then required to engage with the unlocking mechanism on the cage. When the spring is unlocked, pull the ring 2 backward, and the unlocking point 221 moves backward to unlock with the unlocking spring on the cage. During the process of pulling the ring 2 backward, the spring 231 can abut against the bottom of the groove 131 and deform. When the external force is released, the spring 231 will reset the unlocking arm 220 in the process of returning to its original state. By designing the spring 231 on the ring 2 and the groove 131 on the structural component 1, the cooperation of the two can replace the spring, that is, achieve spring-free operation. The module can first complete the assembly of the structural component 1 and the engine, and then carry out the preliminary testing process. Then, pull rings 2 of different colors or markings can be installed, so as not to affect the already assembled structural component 1 and engine, and also without retesting.

[0022] Example 2 like Figure 7 , Figure 8 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: The connection between the limiting block 222 and the unlocking arm 220 is a smooth arc shape. When the limiting block 222 is pressed into the stroke groove 120, the smooth arc shape helps the limiting block 222 to be pressed into the stroke groove 120. At least part of the projection of each limiting block 222 on the unlocking arm 220 is in the slide groove 110 or at least part of the projection coincides with the slide groove 110. In this way, the limiting block 222 is partially embedded in the slide groove 110 in its natural state, making it easier to squeeze in.

[0023] Example 3 like Figures 1 to 8 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below: Each unlocking arm 220 has a limiting block 222 that is inclined from the inside out above its unlocking point 221, and another limiting block 222 that is inclined from the inside out below its unlocking point 221. That is, each unlocking arm 220 has two limiting blocks 222. Each slide groove 110 has a travel groove 120 on its bottom and a travel groove 120 on its top. That is, each slide groove 110 has two travel grooves 120, and the two limiting blocks 222 on each unlocking arm 220 are respectively located in the two travel grooves 120 on the same side as the unlocking arm 220.

[0024] Furthermore, a notch 132 is provided on the bottom surface of the base 130 in structural component 1, which is connected to the travel groove 120.

[0025] Part of the travel groove 120 is located on the base 130 in the structural component 1, while the other part of the travel groove 120 is located on the upper cover 140 in the structural component 1. That is, each travel groove 120 is composed of two parts.

[0026] Example 4 like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, this embodiment is a further improvement on embodiment 1, 2, or 3, as detailed below: On the end face of the tail end of the structural component 1, a limiting groove 150 is opened at each corresponding slide groove 110, which is distributed along the length direction of the structural component 1. Each limiting groove 150 is connected to the slide groove 110 on the same side. Each unlocking arm 220 in each slide groove 110 is provided with a limiting piece 223 that enters the limiting groove 150. The connection between the limiting piece 223 and the unlocking arm 220 is bent inward. When the pull ring 2 is installed, the limiting pieces 223 on the two unlocking arms 220 can first enter the limiting groove 150, and then press the limiting block 222 inward so that the limiting block 222 deforms and enters the stroke groove 120.

[0027] Furthermore, the limiting groove 150 is located on the upper cover 140 in the structural component 1.

[0028] Example 5 like Figure 2 , Figure 4 , Figure 7 , Figure 8 As shown, this embodiment is a further improvement on embodiment 1, 2, 3, or 4, as detailed below: On the substrate 230, a first through groove 232 and a second through groove 233 that are not connected to each other are formed in the area where the spring piece 231 is located. Since the first through groove 232 and the second through groove 233 are not connected to each other, an arc-shaped strip 234 will be formed on the substrate 230 in the area between the first through groove 232 and the second through groove 233. The spring piece 231 is connected to the arc-shaped strip 234, and the arc-shaped strip 234 is used to increase the elasticity and deformation of the spring piece 231.

[0029] Furthermore, the spring piece 231 is located in the middle area of ​​the arc-shaped strip 234, and the arc-shaped strip 234 and the spring piece 231 are integrally formed.
