Description

Technical Field

[0001] This utility model belongs to the field of optical modules, and specifically relates to an optical module housing. Background Technology

[0002] Optical modules typically work in conjunction with switches. The pull ring of the optical module is compatible with the locking / unlocking mechanism in the switch, allowing the optical module to be locked / unlocked by operating the pull ring. Currently, the optical module housing generally includes a base, a pull ring, and a top cover. The optical engine is installed inside the base (the specific type of optical engine depends on the type of optical module housing). The pull ring is installed at the connection between the base and the top cover. Spring holes are provided on both sides of the optical module housing to install compression springs. The compression springs act on the pull ring, using them to reset the pull ring. The current assembly structure of the pull ring and optical module housing has the following problems: 1) Insufficient limiting of the pull ring and compression spring, making it easy for the pull ring and spring to misalign during use, affecting long-term stability; 2) The assembly of the base, top cover, compression spring, and pull ring is relatively complex and time-consuming. Utility Model Content

[0003] The purpose of this invention is to provide an optical module housing that can be used stably for a long time and is easy to assemble.

[0004] The technical solution adopted in this utility model is: An optical module housing includes a base, a pull ring, and a top cover. The base has positioning posts on both sides, each with a torsion spring. The torsion spring has three force points: the middle force point is fitted onto the positioning post, and the two outer force points are respectively limiting arms and extension arms extending to both sides. The limiting arms are limited by components on the base. The pull ring includes a pair of unlocking tabs. The two unlocking tabs are connected at one end via a handle, and each end has an unlocking part. The two unlocking tabs are slidably mounted on both sides of the base via a guide structure. The handle is used to pull the unlocking tabs outward, and the unlocking parts are used to trigger unlocking when sliding outward. Torsion spring baffles are provided on the two unlocking tabs, and these baffles abut against the extension arms on both sides. When the unlocking tab slides outward, it causes the torsion spring baffles to press against the extension arms. When the unlocking tab is released, the torsion spring causes the unlocking tab to return to its original position via the extension arms and the torsion spring baffles. The top cover is mounted on the base.

[0005] Preferably, the extension arm is angled upward, the torsion spring baffle abuts against the upper part of the extension arm, and the limiting arm is hooked horizontally and then downward into the limiting arm positioning groove of the base.

[0006] Preferably, the torsion spring stop is engaged with the extension arm through an opening slot.

[0007] Preferably, the base has torsion spring mounting grooves on both sides, the positioning post is located on the torsion spring mounting groove, the torsion spring is located in the torsion spring mounting groove, and the torsion spring baffle extends into the torsion spring mounting groove.

[0008] Preferably, after the unlocking slider is slidably installed on the side of the base, it cooperates with the side of the base to axially limit the middle force point of the torsion spring on the positioning post.

[0009] Preferably, the guide structure includes a bottom guide block located at the bottom of the unlocking slide and a base groove located at the bottom of the side of the base, with the bottom guide block slidably fitted within the base groove.

[0010] Preferably, the top of the unlocking slider is provided with a top guide block, and the bottom of the top cover side has a top cover groove, in which the top guide block slides and engages with the top cover groove.

[0011] Preferably, the torsion spring stop is formed by punching and bending directly on the unlocking slide, with the root of the torsion spring stop connected to the unlocking slide and the remaining part separated from the unlocking slide by punching.

[0012] Preferably, the top cover and the base are connected by screws, and the top cover and the base are provided with corresponding threaded holes.

[0013] Preferably, the unlocking part is an outwardly protruding structure.

[0014] The beneficial effects of this utility model are: The pull ring slides with the two sides of the base through the unlocking sliders on both sides. The torsion spring is sleeved on the positioning post and then held in place by the torsion spring stop plate to complete the positioning of position and direction. Both have sufficient limits and will not deviate, so it can be used stably for a long time. First, put the torsion spring on the positioning post, then install the pull ring on the base, and finally install the top cover on the base. The pull ring can be pre-assembled, and the key is that the assembly is convenient. Attached Figure Description

The torsion spring 310 has three force points: the middle force point is sleeved on the positioning post 301, and the two side force points are respectively the limiting arms 311 and the extension arms 312 extending to both sides. The limiting arms 311 are limited by components on the base 300, see Figures 2 to 4 The pull ring 100 includes a pair of unlocking slides 120. Each unlocking slide 120 is connected at one end by a handle 110 and at the other end by an unlocking part 122. The unlocking slides 120 are slidably mounted on both sides of the base 300 via a guide structure. The handle 110 is used to pull the unlocking slides 120 outwards, and the unlocking part 122 is used to trigger unlocking when sliding outwards. Each unlocking slide 120 has a torsion spring stop 121, which abuts against the extension arms 312 on both sides. When the unlocking slide 120 slides outwards, it causes the torsion spring stop 121 to press against the extension arms 312. When the unlocking slide 120 is released, the torsion spring 310, through the extension arms 312 and the torsion spring stop 121, causes the unlocking slide 120 to return to its original position. Figures 1 to 4 The top cover 200 is mounted on the base 300, see... Figure 1 .

[0022] The pull ring 100 slides with the two sides of the base 300 through the unlocking slides 120 on both sides. The torsion spring 310 is sleeved on the positioning post 301 and then held in place by the torsion spring baffle 121 to complete the positioning of position and direction. Both have sufficient limit and will not deviate, so it can be used stably for a long time. First, the torsion spring 310 is sleeved on the positioning post 301, then the pull ring 200 is installed on the base 300, and finally the top cover 200 is installed on the base 300. The pull ring 200 can be pre-assembled, and the key is that the assembly is convenient.

[0023] like Figure 1 and Figure 4As shown, in this embodiment, preferably, the guide structure includes a bottom guide block 123 located at the bottom of the unlocking slide 120 and a base groove 305 located at the bottom side of the base 300, with the bottom guide block 123 slidably engaged within the base groove 305; a top guide block 124 is provided at the top of the unlocking slide 120, and a top cover groove 201 is located at the bottom side of the top cover 200, with the top guide block 124 slidably engaged within the top cover groove 201. Two sets of sliding engagement methods are used on each side, ensuring reliable guidance.

[0024] like Figure 1 and Figure 4 As shown, in this embodiment, preferably, the torsion spring baffle 121 is formed by punching and bending directly on the unlocking slide 120. The root of the torsion spring baffle 121 is connected to the unlocking slide 120, and the rest is separated from the unlocking slide 120 by punching, which is convenient to manufacture.
