Abstract
Description
Technical Field
[0001] This utility model belongs to the field of communication equipment technology, specifically relating to a locking device and an optical fiber distribution box. Background Technology
[0002] Fiber optic distribution boxes are core wiring devices used for fiber optic termination, distribution, scheduling, and physical protection in fiber optic communication networks, and are commonly used in fiber optic wiring in computer rooms.
[0003] In the daily operation and maintenance of fiber optic distribution boxes, it is necessary to remove the tray from the box to plug in, unplug, and inspect the wiring modules on the tray. Conventional fiber optic distribution boxes typically have a slide rail between the box body and the tray, allowing the tray to be pulled out by sliding along the rail. To ensure the tray remains stably inside the distribution box, a rubber retainer is usually installed at the mating point between the tray and the slide rail. The resistance between the rubber retainer and the slide rail structure prevents the rail from sliding out automatically, thus preventing the tray from slipping out of the distribution box. However, the frictional resistance of the rubber retainer is relatively low, and operators can easily pull the tray out of the distribution box by accident. Furthermore, the rubber retainer gradually wears down during repeated pulling and unplugging, causing its resistance to decrease and the tray to lose its locking mechanism with the distribution box, affecting the normal operation of the distribution box. Utility Model Content

The elastic element abuts against one side of the snap-fit part. When the snap-fit part swings a set distance toward the elastic element, the swing rod extends out of the assembly surface and swings into the end face where the assembly surface is located.
[0006] As a further improvement of this utility model, the swing groove is provided with an abutment post, and the elastic element includes a torsion spring provided on one side of the abutment post.

[0011] As a further improvement of this utility model, the rotating column includes two second clamping pieces extending toward the swing arm, with a compression gap between the two second clamping pieces, and a second limiting protrusion provided at the end of the two second clamping pieces away from the mounting body.
[0012] As a further improvement of this utility model, the mounting body is recessed inward to form the mounting surface, and the mounting surface is circumferentially formed with a first abutting wall and a second abutting wall, the first abutting wall and the second abutting wall protruding from the surface of the mounting surface; The swing arm extends out of the mounting surface and forms a locking part. One side of the locking part abuts against the first abutting wall. The first abutting wall and the elastic element are located on both sides of the swing arm, respectively. The swing arm has an unlocking part formed at the end opposite to the locking part, and a swing gap is left between the unlocking part and the second abutment wall.
[0013] As a further improvement of this utility model, the unlocking part extends toward the mounting body, the mounting body is provided with a through groove along the extending direction of the unlocking part, and the unlocking part is disposed in the through groove.
[0014] This utility model also includes an optical fiber distribution box, which comprises: The box body is hollow inside and has an opening along a first direction.

A rotating part and a snap-fit part are provided on the swing rod, and an elastic element is provided in the swing groove. The elastic element is provided in the swing direction of the swing rod to prevent the swing rod from swinging arbitrarily. When it is necessary to unlock the tray and the fiber optic distribution box, the elastic element is squeezed by the swing rod, the elastic element deforms accordingly, and the locking part of the swing rod extends into the end face of the assembly surface. The locking part disengages from the notch on the box, and the tray and the fiber optic distribution box are unlocked. The overall unlocking is convenient and quick. Attached Figure Description

[0024] Example: Please see Figures 1-8 The locking device 1 in the preferred embodiment of this utility model includes a mounting body 101, on which a mounting surface is provided; and a swing rod 102, which is disposed on the mounting surface, with one end of the swing rod 102 extending out of the end face of the mounting surface; the swing rod 102 is provided with a rotating part and a locking part arranged at intervals along the extending direction, and both the rotating part and the locking part are disposed facing the mounting body 101. The rotating part is rotatably connected to the mounting body 101, and the swing rod 102 can swing relative to the mounting body 101, so that the end of the swing rod 102 extending out of the mounting surface protrudes or is received within the end face of the mounting surface; the mounting body 101 has a swing groove facing the locking part, the locking part extends into the swing groove, and a swing gap is left between the locking part and the swing groove; simultaneously, an elastic element is also provided in the swing groove, the elastic element abuts against one side of the locking part, and when the locking part swings a set distance toward the elastic element, the end of the swing rod 102 extending out of the mounting surface swings into the end face of the mounting surface.
[0025] Specifically, the locking device 1 in this utility model is installed on the tray 3. A locking part 1026 is formed by the end face of the mounting surface extending from the swing rod 102. The locking part 1026 matches the notch on the side wall of the fiber optic distribution box 2 to achieve stable locking between the tray 3 and the box 2, preventing the tray 3 from accidentally sliding out of the fiber optic distribution box. A rotating part and a snap-fit part are provided on the swing rod 102, and an elastic element is provided on the mounting body 101. The elastic element, located in the swing direction of the swing rod 102, prevents arbitrary swinging of the swing rod 102. When it is necessary to unlock the tray 3 from the fiber optic distribution box, the swing rod 102 presses against the elastic element, causing the elastic element to deform accordingly. The locking part 1026 of the swing rod 102 then extends into the end face of the mounting surface, disengaging the locking part 1026 from the notch on the box 2. The tray 3 is thus unlocked from the fiber optic distribution box, making the overall unlocking process convenient and quick.
[0026] As an optional embodiment of this utility model, the elastic element in this utility model can be elastic rubber, spring, etc., disposed in the swing groove. When the locking part moves toward the elastic element, the elastic rubber or spring is compressed and deformed accordingly, so that the swing rod 102 can swing, thereby realizing the switching of the locking part 1026 protruding from the assembly surface and rotating and retracting into the assembly surface, completing the locking and unlocking work of the fiber optic distribution box. The locking device 1 in this application is used to lock the tray 3 and the box 2. The set distance of the locking part swinging toward the elastic element can be pre-designed according to the position of the tray 3 and the box 2. Optionally, the locking state of the locking device 1 can also be determined according to the rotation angle of the swing rod 102 around the rotating part. Of course, alternatively, in addition to the fiber optic distribution box in this utility model, other daily pull-out box structures 2 or other lockable structures that require locking can also be locked using the locking device 1.
[0027] Furthermore, such as Figure 5 As shown, in an optional embodiment of this utility model, the swing groove is provided with an abutment post 1011, and the elastic element includes a torsion spring 1012 disposed on one side of the abutment post 1011. The torsion spring 1012 includes a first elastic cantilever 1013 and a second elastic cantilever 1014. The first elastic cantilever 1013 abuts against the side wall of the abutment post 1011, and the second elastic cantilever 1014 abuts against the locking part. By setting the abutment post 1011 and the locking part, and then arranging the torsion spring 1012 between them, the torsion of the torsion spring 1012 is used to limit the locking part, thereby limiting the end of the swing rod 102 protruding from the assembly surface. When unlocking is required, the swing rod 102 is swung, the locking part presses against the torsion spring 1012, and the torsion spring 1012 is tightened under the double action of the abutment post 1011 and the locking part, the swing rod 102 swings accordingly, and the locking device 1 completes the unlocking.
[0028] Furthermore, such as Figure 3As shown, in an optional embodiment of this utility model, the snap-fit portion includes a mounting buckle 1021 extending toward the mounting body 101, and a torsion spring 1012 sleeved on the mounting buckle 1021. The torsion spring 1012 needs to be twisted in its original position to provide elastic force. Therefore, this utility model provides a mounting buckle 1021 on the swing arm 102. By stringing the torsion spring 1012 onto the mounting buckle 1021, the torsion spring 1012 is locked between the abutment post 1011 and the snap-fit portion, and elastic force can be applied to the snap-fit portion.
[0029] Optionally, the mounting clip 1021 is only used to limit the position of the torsion spring 1012, and does not limit the specific position of the mounting clip 1021. Therefore, the mounting clip 1021 can be fixedly connected to the swing rod 102 at one end and extend towards the mounting body 101 at the other end, or it can be fixedly connected to the bottom surface of the swing groove at one end and extend towards the swing rod 102 at the other end.
[0030] Furthermore, as an optional embodiment of this utility model, the mounting buckle 1021 includes two first clamping pieces 1022 extending towards the mounting body 101, with a compression gap between the two first clamping pieces 1022, and a first limiting protrusion 1023 is provided at the end of the two first clamping pieces 1022 facing away from the swing rod 102. Through the cooperation between the first limiting protrusion 1023 and the clamping pieces, the torsion spring 1012 can be sleeved on the mounting buckle 1021 and will not fall off, ensuring the stable use of the torsion spring 1012. When the torsion spring 1012 needs to be replaced, by pressing the two first clamping pieces 1022 close together, so that the outer diameter of the two first limiting protrusions 1023 is smaller than the inner diameter of the torsion spring 1012, the torsion spring 1012 can be removed normally. It is understandable that the sum of the outer diameters of the two first limiting protrusions 1023 and the length of the compression gap is greater than the inner diameter of the torsion spring 1012, and the sum of the outer diameters of the two first limiting protrusions 1023 is less than the inner diameter of the torsion spring 1012.
[0031] Furthermore, such as Figure 4As shown, in an optional embodiment of this utility model, the snap-fit portion includes a first limiting wall 1024 and a second limiting wall 1025 extending toward the mounting body 101. The first limiting wall 1024 and the second limiting wall 1025 are arranged at an angle to each other, and the mounting buckle 1021 is located within the angled area formed by the first limiting wall 1024 and the second limiting wall 1025. The first elastic cantilever 1013 abuts against the first limiting wall 1024, and the second elastic cantilever 1014 abuts against the second limiting wall 1025. By having a torsion spring 1012 abut against the first limiting wall 1024 and the second limiting wall 1025, the torsion spring 1012 can constrain the swing rod 102 to a set position, thereby achieving stable locking of the locking device 1 onto the external housing 2. Furthermore, the torsion spring 1012 is constrained by the first limiting wall 1024 and the second limiting wall 1025, so that the torsion spring 1012 has a certain elastic force after initial compression, which facilitates the torsion spring 1012 to limit the swing arm 102. When unlocking is required, the torsion spring 1012 is pressed by the snap-fit part, so that the swing arm 102 swings to complete the unlocking of the locking device 1 from the external box 2. It is worth noting that the second elastic cantilever 1014 abuts against the second limiting wall 1025 and the abutment post 1011 respectively. The cross-section of the second limiting wall 1025 and the abutment post 1011 is flush, so that the second limiting wall 1025 does not affect the limiting of the second elastic cantilever 1014 by the abutment post 1011.
[0032] Further, as an optional embodiment of this utility model, the rotating part includes a rotating column 1015 disposed on the mounting body 101 and a rotating hole 1028 disposed on the swing arm 102. The rotating column 1015 is disposed facing the swing arm 102 and passes through the rotating hole 1028. Through the cooperation of the rotating column 1015 and the rotating hole 1028, the relative rotation between the swing arm 102 and the mounting body 101 can be realized to complete the locking and unlocking of the locking device 1. Optionally, the rotating column 1015 can also be disposed on the swing arm 102, and the rotating hole 1028 can be disposed on the mounting body 101.
[0033] Furthermore, as an optional embodiment of this utility model, the rotating column 1015 includes two second clamping pieces 1016 extending toward the swing arm 102, with a compression gap between the two second clamping pieces 1016, and a second limiting protrusion 1017 provided at the end of the two second clamping pieces 1016 facing away from the mounting body 101. The structure of the rotating column 1015 is similar to that of the mounting buckle 1021. The dimensional relationship between the second limiting protrusion 1017, the mounting gap, and the rotating hole 1028 will not be described in detail. Through the cooperation between the second clamping pieces 1016 and the second limiting protrusion 1017, the rotating column 1015 and the swing arm 102 can be detachably connected, facilitating the assembly, disassembly, and maintenance of the swing arm 102 and the mounting body 101.
[0034] Furthermore, as an optional embodiment of this utility model, the mounting body 101 of this utility model is recessed inward to form the aforementioned mounting surface, and a first abutment wall 1018 and a second abutment wall 1019 are formed on the circumferential side of the mounting surface, both of which protrude from the surface of the mounting surface. A locking part 1026 is formed at one end of the swing rod 102 extending from the mounting surface. One side of the locking part 1026 abuts against the first abutment wall 1018, and the first abutment wall 1018 and the elastic element are respectively located on both sides of the swing rod 102. The arrangement of the first abutment wall 1018 and the elastic element on both sides of the swing rod 102 ensures that the swing rod 102 can only swing towards the side of the elastic element, avoiding the possibility of the swing rod 102 swinging in the opposite direction and ensuring the stability of the locking between the locking device 1 and the housing 2. Furthermore, an unlocking part 1027 is formed at the end of the swing arm 102 away from the locking part 1026, and a swing gap is left between the unlocking part 1027 and the second abutment wall 1019. The unlocking part 1027 is essentially the other end of the swing arm 102. When it is necessary to unlock the outer box 2 by the locking device 1, the unlocking part 1027 is moved towards the second abutment wall 1019 by moving the unlocking part 1027. At this time, the locking part 1026 retracts, and the unlocking work is completed. The swing gap between the unlocking part 1027 and the second abutment wall 1019 can both ensure that the locking device 1 can complete the unlocking work and indicate to the operator the unlocking status of the fiber optic distribution box, making it convenient for the operator to pull out the tray 3.
[0035] Optionally, the swing arm 102 in this utility model can be a straight rod, or it can be a Z-shaped irregular rod depending on the shape of the mounting body 101.
[0036] Furthermore, as an optional embodiment of this utility model, the unlocking part 1027 extends towards the side of the mounting body 101, and the mounting body 101 is provided with a through groove along the extending direction of the unlocking part 1027, with the unlocking part 1027 disposed within the through groove. Normally, the lever 102 is a sheet-like structure disposed on the back of the mounting body 101. When the locking device 1 is disposed on the tray 3, the main body of the tray 3 is embedded inside the box 2, making it difficult for workers to reach into the back of the mounting body 101 to move the lever 102. Therefore, by providing a through groove on the mounting body 101, and allowing the unlocking part 1027 to extend into the through groove, when unlocking is required, workers can reach into the through groove through the front of the mounting body 101 to move the lever 102 and complete the unlocking operation.
[0037] Furthermore, such as Figure 7 , Figure 8As shown, as an optional embodiment of the present invention, the present invention also includes an optical fiber distribution box, which includes a box body 2, the box body 2 is hollow inside, and the box body 2 is open along a first direction. The two sides of the opening are provided with side walls of the box body 2, and at least one of the side walls of the box body 2 is provided with a locking notch 201 near the opening; and a tray 3, the tray 3 is slidably embedded in the box body 2 along the first direction, and the locking device 1 is provided at one end of the tray 3 facing the opening; wherein, one side of the mounting surface of the locking device 1 is flush with the side wall of the box body 2, and the swing rod 102 of the locking device 1 extends out of the end face of the mounting surface and is engaged at the locking notch 201.
[0038] The fiber optic distribution box of this invention uses a locking device 1 on the tray 3. The locking part 1026 of the locking device 1 (the end of the swing rod 102 extending from the mounting surface) is engaged with the locking notch 201 on the side wall of the box body 2 to achieve relative locking between the tray 3 and the fiber optic distribution box. When unlocking is required, the swing rod 102 is moved, and the locking part 1026 of the swing rod 102 swings towards the inside of the mounting body 101. The locking part 1026 disengages from the locking notch 201, and the tray 3 and the box body 2 can slide relative to each other, allowing the tray 3 to be pulled out of the box body 2.
[0039] Optionally, the locking devices 1 in this utility model are arranged in pairs. Locking notches 201 are provided on the side walls of the box 2 on both sides of the opening. Locking devices 1 are provided at both ends of the tray 3 facing the opening, and the locking parts 1026 of the two locking devices 1 are engaged at the locking notches 201.
[0040] The locking device 1 in this utility model works as follows: When unlocking is required, the unlocking part 1027 is moved toward the second abutment wall 1019, and the swing arm 102 swings around the rotating column 1015. At this time, the abutment column 1011 presses against the first elastic cantilever 1013, the first elastic cantilever 1013 retracts, and the swing arm 102 can swing normally. The locking part 1026 of the swing arm 102 swings to the end face of the assembly surface, and the locking part 1026 no longer protrudes from the mounting body 101. The locking device 1 and the housing 2 are unlocked, and the tray 3 can be pulled out from the housing 2. When locking is required, The tray 3 slides into the box 2. The operator releases the unlocking part 1027, and the swing arm 102 can swing freely. The torsion spring 1012 loses its resistance and unfolds freely. The first elastic cantilever 1013 applies elastic force towards the first limiting wall 1024. The swing arm 102 swings around the rotating column 1015. The locking part 1026 moves towards the first abutting wall 1018. The locking part 1026 protrudes from the end face of the assembly surface and is engaged with the locking notch 201 of the box 2. The locking device 1 completes the locking of the fiber optic distribution box.
[0041] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
