In the embodiment of the present invention, as shown in fig. 1 and fig. 2, an optical module 100 provided by the present invention includes:
the shell 10, the shell 10 has accommodating chambers 13, and the shell 10 also has lock holes 114 and perforations 113 communicated with the accommodating chambers 13;
the unlocking piece 20 is limited and installed in the accommodating cavity 13, one side of the unlocking piece 20 is provided with a clamping hook 21, the clamping hook 21 penetrates through the lock hole 114 or is separated from the lock hole 114, and the unlocking piece 20 is provided with a through hole 200 corresponding to the through hole 113;
the limiting piece 30, the limiting piece 30 penetrates through the through hole 113 and the through hole 200 to limit and install the unlocking piece 20 in the accommodating cavity 13; and
the pulling piece 40, the pulling piece 40 is connected with the unlocking piece 20, and the pulling piece 40 is used for driving the unlocking piece 20 to lock or unlock with the switch.
According to the technical scheme, the through hole 113 is formed in the shell 10, the through hole 200 is formed in the unlocking piece 20, and the limiting piece 30 penetrates through the through hole 113 and the through hole 200 to limit the unlocking piece 20 to the accommodating cavity 13 in the shell 10, the optical module 100 only needs one limiting piece 30 to limit the unlocking piece 20 in the accommodating cavity 13, the problem that the unlocking piece 20 is limited by a plurality of limiting pieces 30 in the existing optical module 100 is solved, materials are saved, the unlocking piece 20 and the clamping hook 21 are not easy to be pushed by the pulling piece 40 to move back and forth in the accommodating cavity 13, then the clamping hook 21 is blocked by the shell 10, and the situation that the clamping hook 21 cannot penetrate through the locking hole 114 due to back and forth movement after being unlocked and the clamping hook 21 cannot lock the switch is avoided.
The unlocking part 20 can drive the hook 21 to lift and lock the switch by taking the limiting part 30 as a fulcrum according to a lever principle; when the unlocking piece 20 is driven by the pulling piece 40 to tilt up, the hook 21 is pulled out of the lock hole 114, and the hook 21 is unlocked from the switch; when the unlocking piece 20 falls back and resets, the hook 21 penetrates through the lock hole 114, the hook 21 is locked with the switch, and the unlocking operation and the locking operation only need to pull the pulling piece 40, so that time and labor are saved.
In addition, the unlocking member 20 has a plate-shaped structure, and the unlocking member 20 is horizontally installed in the accommodating chamber 13. The housing 10 may be a split structure or an integrated structure. If the housing 10 is provided with the accommodating cavity 13, the unlocking member 20 is installed in the accommodating cavity 13, and then the limiting member 30 is screwed into the through hole 113 and the through hole 200, so that the unlocking member 20 is connected with the housing 10, and the unlocking member 20 cannot be separated from the accommodating cavity 13. If the housing 10 is a split structure, the limiting member 30 can connect the split housing 10 together while the unlocking member 20 is installed. The invention only needs one limiting piece 30, not only the unlocking piece 20 is installed in the accommodating cavity 13, but also the split type shell 10 is connected together, and the optical module 100 of the invention has the advantages of less material use, low cost, quick installation and high efficiency.
In one embodiment, the hook 21 is in a hook-like configuration so that the hook 21 is locked to the switch.
Further, in order to prevent the unlocking member 20 from being completely pressed by the housing 10 or the limiting member 30 and being unable to tilt, a gap 110 is formed between the unlocking member 20 and the top wall of the accommodating chamber 13, so that when the unlocking member 20 is pulled by the pulling member 40, the unlocking member 20 can tilt up or fall back in the accommodating chamber 13, and the hook 21 is driven to disengage from the locking hole 114 or pass through the locking hole 114.
In order to avoid the limiting member 30 from excessively pressing the unlocking member 20 to cause the unlocking member 20 not to tilt, the housing 10 includes an upper cover 11 and a base 12, the upper cover 11 and the base 12 are connected and enclose the accommodating cavity 13, the base 12 or the upper cover 11 is provided with an installation cylinder 120 in a protruding manner towards the accommodating cavity 13, the unlocking member 20 is sleeved on the installation cylinder 120, and the limiting member 30 penetrates through the through hole 113 and the through hole 200 and is installed on the installation cylinder 120 to limit the unlocking member 20 between the upper cover 11 and the base 12.
In an embodiment, the base 12 is provided with a mounting cylinder 120 protruding toward the accommodating cavity 13, the mounting cylinder 120 supports the upper cover 11, and the stopper 30 penetrates through the through hole 113 of the upper cover 11 and the through hole 200 of the unlocking member 20 and stops at the mounting cylinder 120, so as to connect the upper cover 11 and the base 12. Meanwhile, the unlocking piece 20 is limited in the accommodating cavity 13 by the limiting piece 30, and the unlocking piece 20 can be installed in the accommodating cavity 13, the upper cover 11 is connected with the base 12 through the limiting piece 30, so that time and labor are saved, and materials are saved.
Further, a gap 110 is arranged between the unlocking piece 20 and the upper cover 11, the size of the gap 110 may affect the lifting amplitude of the unlocking piece 20 to a certain extent, and if the gap 110 is too small, the unlocking piece 20 is pressed in the accommodating cavity 13 and cannot lift; if the clearance 110 is too large, the unlocking piece 20 is too loose in the accommodating cavity 13, and the pulling piece 40 is not easy to drive the unlocking piece 20 to lift. In one embodiment, the optical module 100 supports the upper cover 11 through the mounting tube 120 to space the upper cover 11 from the unlocking member 20, thereby providing a space for the unlocking member 20 to ascend and descend.
As shown in fig. 1 to 3, in order to prevent the unlocking member 20 from moving forward and backward or shaking left and right during unlocking or locking, the unlocking member 20 is provided with two opposite side edges 22 and a connecting edge 23 connecting the two side edges 22, the connecting edge 23 is connected with the hook 21, the two side edges 22 are convexly provided with a shaft portion 25, and the shaft portion 25 is rotatably installed in the accommodating cavity 13.
In one embodiment, the two sides 22 of the unlocking member 20 are provided with shaft portions 25, and the shaft portions 25 are defined in the accommodating chamber 13 by the upper cover 11 and the base 12. Specifically, the upper cover 11 and the base 12 are provided with mounting grooves 131 recessed in correspondence with the shaft portions 25, and the shaft portions 25 are rotatably mounted to the mounting grooves 131. When the unlocking member 20 is pulled by the pulling member 40 to move up and down, the shaft portion 25 and the stopper 30 restrict the forward and backward movement of the unlocking member 20, and the unlocking member 20 can move up and down like a seesaw, with the shaft portion 25 as a fulcrum. And because the hook 21 is limited by the limiting piece 30 and the shaft portion 25 to move back and forth, the hook 21 can be easily reset back to the lock hole 114 without being blocked by the shell 10, and the situation that the hook 21 cannot penetrate through the lock hole 114 due to back and forth displacement after being unlocked and the switch cannot be locked by the hook 21 is avoided. The shaft 25 is a cylindrical structure, and the mounting groove 131 is correspondingly configured to be a circular groove structure, so that the shaft 25 can rotate in the mounting groove 131.
In order to assemble the unlocking piece 20 and the pulling piece 40 together, a surrounding stopping piece 24 is arranged on one side of the unlocking piece 20, which is far away from the hook 21, and the pulling piece 40 is detachably arranged on the surrounding stopping piece 24;
the pulling element 40 is used for driving the unlocking element 20 to tilt up or fall back to reset so as to drive the hook 21 to be out of the lock hole 114 or to penetrate through the lock hole 114, and further unlocking or locking the hook 21 and the switch.
In one embodiment, the pulling member 40 is detachably mounted to the unlocking member 20 to facilitate subsequent replacement of the unlocking member 20 or the pulling member 40. When the pulling member 40 needs to be removed and replaced, the limiting member 30 is firstly screwed out of the upper cover 11 and then removed, the upper cover 11 is then removed from the base 12, then the unlocking member 20 can be taken out of the accommodating cavity 13, and finally the pulling member 40 can be taken out of the accommodating cavity 13. The pulling piece 40 and the unlocking piece 20 adopt a split structure, so that the problem that the pulling piece 40 and the unlocking piece 20 are required to be replaced together when one of the pulling piece 40 or the unlocking piece 20 is damaged is solved, the waste of the pulling piece 40 or the unlocking piece 20 is reduced, and the service life of the pulling piece 40 or the unlocking piece 20 is prolonged. The enclosure piece 24 encloses the pull piece 40, and the pull piece 40 is installed in the enclosure piece 24 in a limiting manner and rotates in the enclosure piece 24 to lift the enclosure piece 24. In addition, the upper cover 11 is mounted on the base 12 through a stopper 30, and the upper cover 11 restricts the lifting range of the unlocking member 20. Even if the upper cover 11 does not limit the pulling piece 40, the upper cover 11 is not connected with the pulling piece 40 or does not press against the pulling piece 40, the pulling piece 40 can still be limited in the enclosing piece 24 by the enclosing piece 24 of the unlocking piece 20, and the installation stability of the pulling piece 40 is ensured.
As shown in fig. 1 to 4, in order to facilitate the operator to pull the pulling element 40, the pulling element 40 includes a pulling tab 41 and a cam rotating element 42, the pulling tab 41 is connected to the cam rotating element 42, the cam rotating element 42 is rotatably mounted on the surrounding blocking member 24, and the cam rotating element 42 can lift the surrounding blocking member 24.
In one embodiment, the pulling member 40 is provided with a pulling tab 41 to facilitate the pulling of the pulling member 40 by the operator. The pull buckle 41 is of a square buckle structure, and the side edge of the pull buckle 41 can be printed with key information of a product, so that information such as a product name and a model can be obtained through the pull buckle 41. When the optical module 100 is locked with the switch, the tab 41 is locked with the base 12 to prevent the tab 41 from shaking.
When the optical module 100 needs to be unlocked from the switch, the tab 41 is pulled clockwise, the tab 41 rotates and drives the cam rotator 42 to rotate clockwise in the enclosure 24, and the protrusion structure on the cam rotator 42 can lift up the enclosure 24 of the unlocking piece 20. At this time, the hook 21 on the connecting side 23 of the unlocking piece 20 descends and is separated from the locking hole 114, so that the hook 21 is unlocked from the switch.
In order to limit the cam rotor 42 in the enclosure 24, the enclosure 24 includes an abutting portion 241 and a blocking portion 242, the blocking portion 242 is disposed on a side of the abutting portion 241 away from the hook 21, the blocking portion 242 is bent relative to the abutting portion 241, the abutting portion 241 and the blocking portion 242 define a fixed cavity 243, the cam rotor 42 is mounted in the fixed cavity 243, and the blocking portion 242 is used for blocking the cam rotor 42 from being separated from the fixed cavity 243.
The enclosure 24 provided by the present invention is tilted by the cam rotor 42, and since the stopping portion 242 is bent with respect to the abutting portion 241, the stopping portion 242 can stop the cam rotor 42 from separating from the fixed cavity 243, and further limit the cam rotor 42 in the fixed cavity 243. With such an arrangement, even if the upper cover 11 does not limit the pulling element 40, the upper cover 11 is not connected with the pulling element 40 or does not press the pulling element 40, the pulling element 40 can still be limited in the fixing cavity 243 by the enclosure 24 of the unlocking element 20, and the blocking portion 242 of the enclosure 24 ensures the installation stability of the pulling element 40.
In order to limit the cam rotating member 42 to be installed in the accommodating cavity 13, the cam rotating member 42 includes a cam structure 420 and a rotating shaft 421, the cam structure 420 is disposed to protrude relative to the rotating shaft 421, the cam structure 420 is rotatably installed in the fixing cavity 243, the rotating shaft 421 is connected with the cam structure 420, and the rotating shaft 421 is rotatably installed in the accommodating cavity 13.

The rotating shaft 421 is installed in the positioning groove 132, and the pulling member 40 is not easily pulled to move back and forth when rotating, thereby reducing the occurrence of the phenomenon that the unlocking member 20 is pulled to move back and forth by the pulling member 40.
When the top of the cam structure 420 abuts against the inner wall of the abutting portion 241, the cam structure 420 can lift the abutting portion 241; when the top of the cam structure 420 no longer abuts against the abutting portion 241 and the side of the cam structure 420 is parallel to the abutting portion 241, the blocking member 24 descends and resets, and at this time, the hook 21 ascends and resets into the lock hole 114, so that the hook 21 is locked with the switch. Since the rotation shaft 421 is restricted to rotate in the positioning groove 132, the pulling member 40 is not easily detached from the casing 10.
In order to fasten the pulling buckle 41 on the base 12 without shaking, the pulling buckle 41 is concavely provided with a groove 410, the housing 10 is convexly provided with a projection (not marked in the figure) towards the direction of the groove 410, and the projection and the groove 410 are concavely and convexly matched to limit the pulling buckle 41 on the housing 10.
