Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication equipment technology, specifically to an optical fiber distribution frame for locking and unlocking optical fiber trays. Background Technology

[0002] As a wiring connection device between optical cables and communication equipment, fiber optic distribution frames are used for the termination and distribution of the main optical cables at the central office in optical fiber communication systems, which can facilitate the connection, distribution and scheduling of optical fiber lines.

[0003] In related technologies, fiber optic distribution frames typically include a rack and tray, as well as one or more guide rails arranged on the tray. To accommodate more fiber optic cables within a limited space, several multi-layer fiber optic tray products have emerged on the market, featuring pull-out and flip-up designs.

[0004] The fiber optic module box is located on the tray body. When a fiber optic module box needs maintenance, due to the dense space inside the rack, the traditional method is to pull out the single-layer tray body containing the fiber optic module box separately and place it on the workbench for maintenance. Existing fiber optic patch panels are designed with unlocking and releasing mechanisms for the fiber optic trays. First, in terms of locking reliability, many mechanisms only provide one-way locking, mainly preventing the tray from sliding backward out of the patch panel on its own under vibration or accidental conditions. However, the forward movement limit is often insufficient or missing, which may cause the tray to become embedded under frontal impact or certain operating conditions, affecting the stability of the connection, and may even damage the fiber due to the excessively small bending radius caused by displacement.

[0005] Secondly, in terms of ease of operation, existing designs are often cumbersome. Common unlocking mechanisms require the operator to perform a separate unlocking action first, such as pressing a release button or flipping a latch with a finger. After the lock is released, the tray can then be pulled out. This two-step operation of "unlock first, then pull out" requires the operator to use both hands or complete the operation step by step, which reduces maintenance efficiency and is especially inconvenient in narrow server racks.

[0006] Furthermore, some mechanisms designed to achieve reliable locking are overly complex, involving numerous springs, linkages, or individual buttons. This not only increases manufacturing costs and assembly time but also potentially reduces the overall reliability of the mechanism due to the increased number of parts, raising the risk of failure over long-term use. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fiber optic patch panel for locking and unlocking fiber optic trays. This allows for the fixation of the front and rear ends of the tray body. Furthermore, by simply pulling the unlocking handle in the direction of pulling out the fiber optic tray, the fiber optic tray can be released and simultaneously pulled out, eliminating the need for a two-step operation of pressing to unlock and then pulling out, thus greatly improving installation and maintenance efficiency.

[0008] To solve the above problems, this utility model provides the following technical solution: This utility model provides a fiber optic patch panel for locking and unlocking fiber optic trays, comprising a patch panel body and at least one fiber optic tray. The main body of the patch panel includes at least one layer of slide rails; The fiber optic tray includes a tray body, a first limiting member, a second limiting member, and an unlocking handle; The pallet body includes a bottom wall and two side walls extending upward from both sides of the bottom wall. Each layer of the slide rail includes at least two tracks. The two side walls of each pallet body are slidably disposed on two adjacent tracks of the slide rail in the same layer. Each track is provided with a first limiting part and a second limiting part at its rear end and front end, respectively. The first limiting member and the second limiting member are respectively disposed at the rear end and the front end of the two side walls of the pallet body; The unlocking handle is disposed on the tray body. Pulling the unlocking handle in the first direction can cause the first limiting member and the first limiting part to cooperate, and at the same time cause the second limiting member and the second limiting part to cooperate, thereby locking the tray body. Pulling the unlocking handle in the second direction opposite to the first direction can cause the first limiting member and the first limiting part to separate, and at the same time cause the second limiting member and the second limiting part to separate, thereby releasing the tray body.

[0009] Furthermore, the first limiting member is a first limiting bracket and a second limiting bracket respectively disposed at the rear ends of the two side walls of the tray body. The first limiting bracket includes a first through hole, and the hole wall of the first through hole is provided with a first protrusion extending away from the track. The first limiting part includes a first elastic buckle disposed at the rear end of the two tracks. The first elastic buckle protrudes from the side wall of the track and can be compressed to be flush with the surface of the track. Pulling the unlocking handle along the first direction causes the tray body to slide along the first direction, and the first elastic buckle engages with the first through hole on the first limiting bracket, thereby fixing the tray body and the rear end of the track. Pulling the unlocking handle along the second direction opposite to the first direction causes the tray body to slide along the second direction, and the first protrusion presses against the first elastic buckle, causing the first elastic buckle to undergo elastic deformation and be compressed to be flush with the surface of the track. The first elastic buckle disengages from the first through hole, thereby releasing the fixation of the tray body and the rear end of the track.

[0010] Furthermore, the second limiting member includes a cavity disposed at the front end of the two side walls of the tray body, and a boss is disposed in the cavity in the direction close to the track, the boss not protruding from the outer surface of the side wall of the tray body; the second limiting part includes a second elastic buckle disposed at the rear end of the two tracks, the second elastic buckle part protruding from the side wall of the track and being compressible to be flush with the surface of the track. Pulling the unlocking handle along the first direction causes the tray body to slide along the first direction. The unlocking handle drives the cavity to slide and engage with the second elastic buckle, thereby fixing the tray body and the front end of the track. Pulling the unlocking handle along the second direction opposite to the first direction causes the tray body to slide along the second direction. The unlocking handle drives the boss to press against the second elastic buckle. The second elastic buckle undergoes elastic deformation and is compressed to be flush with the surface of the track. The second elastic buckle disengages from the cavity, thereby releasing the fixation of the tray body and the front end of the track.

[0011] Furthermore, by pulling the unlocking handle in a second direction opposite to the first direction, the unlocking handle causes the second limiting member to press against the second limiting part, while the first limiting member presses against the first limiting part, thereby releasing the fixation of the tray body and the front and rear ends of the track.

[0012] Furthermore, the unlocking handle is located at the front end of the boss and connected to the boss, and the unlocking handle and the boss are integrally formed.

[0013] Furthermore, the first elastic buckle of the first limiting part includes a first base and a first protrusion connected to each other. The outer surface of the first base is flush with the outer surface of the track sidewall. The first protrusion protrudes from the first base toward the fiber optic tray. The first protrusion forms a first guiding surface and a first engaging surface. The distance from the first guiding surface to the last end of the track is less than the distance from the first engaging surface to the last end of the track. The tilt angle between the first guiding surface and the track is less than the tilt angle between the first engaging surface and the track.

[0014] Furthermore, the second elastic latch of the second limiting part includes a second base and a second protrusion connected to each other. The outer surface of the second base is flush with the outer surface of the track sidewall. The second protrusion protrudes from the second base toward the fiber optic tray. The second protrusion forms a second guide surface and a second snap-fit ​​surface. The distance from the second guide surface to the foremost point of the track is less than the distance from the second snap-fit ​​surface to the foremost point of the track. The tilt angle between the second guide surface and the track is less than the tilt angle between the second snap-fit ​​surface and the track.

[0015] Furthermore, the first limiting bracket includes a second through hole, the distance from the second through hole to the last end of the track is less than the distance from the first through hole to the last end of the track, and the wall of the second through hole is provided with a second protrusion extending away from the track; When the tray body is completely pulled out of the fiber optic patch panel, the second through hole and the second limiting part cooperate to restrict the tray body from moving forward; when the tray body is pushed into the fiber optic patch panel, the second protrusion squeezes the second limiting part, and the second through hole disengages from the second limiting part.

[0016] Furthermore, the tail of the first limiting bracket is provided with a third protrusion extending toward a direction away from the track; When the fiber optic tray in its independent state is pushed into the fiber optic patch panel, the third protrusion is used to press against the first limiting part and the second limiting part.

[0017] Furthermore, the fiber optic tray also includes a damping flipping mechanism, which is disposed on both sides of the tray body. One end of the damping flipping mechanism is connected to the first limiting member, and the other end is connected to the tray body, for providing damping buffer when the tray body flips.

[0018] The beneficial effects of this utility model are: by providing a fiber optic distribution frame for locking and unlocking fiber optic trays, the front and rear ends of the fiber optic tray are fixed by the cooperation of the limiting part on the slide rail and the limiting part on the fiber optic tray, which restricts the movement of the tray in both forward and backward directions. The operator only needs to pull the unlocking handle in the direction of pulling out the fiber optic tray to simultaneously complete the two actions of releasing the fiber optic tray and pulling out the fiber optic tray, thereby improving the efficiency of installation and maintenance.

[0024] Please refer to Figure 1 , Figure 1 This is a three-dimensional structural diagram of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. Figure 1As shown, the tray body 21 is located inside the fiber optic patch panel 100. This embodiment provides a fiber optic patch panel 100 for locking and unlocking fiber optic trays, including a patch panel body 1 and at least one fiber optic tray 2. In this embodiment, there are a total of three fiber optic trays 2. The patch panel body 1 includes at least one layer of slide rails 10. Each fiber optic tray 2 includes a tray body 21, a first limiting member 22, a second limiting member 23, an unlocking handle 24, and a damping flipping mechanism 25.

The first limiting member 22 and the second limiting member 23 are respectively disposed on the rear end and the front end of the two side walls of the tray body 21. The unlocking handle 24 is disposed on the tray body 21 and is used to drive the fiber optic tray 2 to move, thereby driving the first limiting member 22 and the second limiting member 23 to move. The damping flipping mechanism 25 is disposed on both sides of the tray body 21. One end of the damping flipping mechanism 25 is connected to the first limiting member 22 and the other end is connected to the tray body 21. It is used to provide damping buffer when the tray body 21 is pulled out to the predetermined position and flipped.

The side facing the operator is the front, and the side away from the operator is the back. Accordingly, the direction in which the tray body 21 is pushed into the patch panel body 1 is the first direction from front to back, and the direction in which the tray body 21 is pulled out of the patch panel body 1 is the second direction from back to front.

[0026] Continue to refer to Figure 1 and Figure 5 , Figure 1 This is a three-dimensional structural diagram of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body 21 being pushed into the patch panel body. At this time, the tray body 21 is located inside the fiber optic patch panel 100. Figure 5 This is a schematic diagram of the structure of the first and second limiting parts of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. Figure 5 As shown, each track 11 has a first limiting part 111 and a second limiting part 112 at its rear and front ends, respectively; Figure 1 As shown, the first limiting member 22 and the first limiting part 111 cooperate to restrict the tray body 21 from moving backward, while the second limiting member 23 and the second limiting part 112 cooperate to restrict the tray body 21 from moving forward, thereby locking the fiber optic tray 2.

[0027] refer to Figure 7 and Figure 8 , Figure 7This is a three-dimensional structural diagram of a single-layer tray body pulled out from the patch panel body, one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. Figure 7 As shown, at this time, the uppermost tray body 21 is completely pulled out of the fiber optic patch panel. Figure 8 for Figure 7 An enlarged schematic diagram of point I in the middle, as shown below. Figure 8 As shown, the first limiting member 22 and the second limiting part 112 cooperate to restrict the tray body 21 from moving forward; at this time, you only need to gently press the tray body 21 that has been fully pulled out and is located on the top layer, and the tray body 21 will flip downward through the damping flipping mechanism 25, which facilitates the subsequent cleaning and maintenance of the fiber optic module box on the tray body 21. Continue to refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the first and second limiting parts of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. Figure 5 As shown, the first limiting part 111 includes a first elastic buckle 1110 disposed at the rear end of the two tracks 11. The first elastic buckle 1110 partially protrudes from the side wall of the track 11 and can be compressed to be flush with the surface of the track 11. The first elastic buckle 1110 of the first limiting part 111 includes a first base 1111 and a first protrusion 1112 connected to each other. The first protrusion 1112 is disposed at a more forward position on the track 11 than the first base 1111. The outer surface of the first base 1111 is flush with the outer surface of the side wall of the track 11. The first protrusion 1112 protrudes from the first substrate 1111 towards the fiber optic tray 2. The first protrusion 1112 forms a first guide surface 1113 and a first snap-fit ​​surface 1114. The distance from the first guide surface 1113 to the last end of the track 11 is less than the distance from the first snap-fit ​​surface 1114 to the last end of the track 11. The inclination angle between the first guide surface 1113 and the track 11 is less than the inclination angle between the first snap-fit ​​surface 1114 and the track 11. When the tray body 21 is pulled out of the fiber optic patch panel 100 along the second direction, it first contacts the first guide surface 1113, making the pulling process easier.

[0028] Continue to refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the first and second limiting parts of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. Figure 5As shown, the second limiting part 112 includes a second elastic buckle 1120 disposed at the front end of the two tracks 11. The second elastic buckle 1120 protrudes from the side wall of the track 11 and can be compressed to be flush with the surface of the track 11. The second elastic buckle 1120 of the second limiting part 112 includes a second base 1121 and a second protrusion 1122 connected to each other. The second protrusion 1122 is disposed at a more rearward position on the track 11 than the second base 1121. The outer surface of the second base 1121 is flush with the outer surface of the side wall of the track 11. The second protrusion 1122 extends from the second base 1121 to the second elastic buckle 1122. The second substrate 1121 protrudes towards the fiber optic tray 2. The second protrusion 1122 forms a second guide surface 1123 and a second snap-fit ​​surface 1124. The distance from the second guide surface 1123 to the foremost end of the track 11 is less than the distance from the second snap-fit ​​surface 1124 to the foremost end of the track 11. The tilt angle between the second guide surface 1123 and the track 11 is less than the tilt angle between the second snap-fit ​​surface 1124 and the track 11. When the tray body 21 is pushed into the fiber optic distribution frame 100 along the first direction, it first contacts the second guide surface 1123, making the pushing process easier.

[0029] In some implementations, reference Figure 2 , Figure 2 This is a top view of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. Figure 2 As shown, the first limiting member 22 consists of a first limiting bracket 221 and a second limiting bracket 222 respectively disposed at the rear ends of the two side walls of the tray body 21. The structure of the second limiting bracket 222 is the same as that of the first limiting bracket 221, and the working principle is the same. This embodiment uses limiting brackets for two reasons: first, the limiting brackets are long enough to precisely limit and extend the sliding stroke of the tray body 21; second, to allow the tray body 21 to slide completely outside the patch panel body. The limiting brackets provide rigid support at this extreme position, thereby ensuring the stability and safety of the tray body 21 in the fully extended state.

[0030] refer to Figure 7 , Figure 10 as well as Figure 11 , Figure 7 This is a three-dimensional structural diagram of a fiber optic patch panel according to one embodiment of the present invention, showing the single-layer tray body being pulled out of the patch panel body. At this time, the uppermost tray body 21 is completely pulled out of the fiber optic patch panel. Figure 10 for Figure 7 An enlarged schematic diagram of the damping flipping mechanism removed at point II. Figure 11 for Figure 7 An enlarged schematic diagram of section III, as shown below. Figure 7 , Figure 10 as well as Figure 11 As shown, the first limiting bracket 221 includes a first through hole 2214 and a second through hole 2215. The distance from the second through hole 2215 to the rear end of the track 11 is less than that of the first through hole 2214. The wall of the first through hole 2214 is provided with a first protrusion 2211 extending away from the track 11. The wall of the second through hole 2215 is provided with a second protrusion 2212 extending away from the track 11. The rear end of the first limiting bracket 221 is provided with a third protrusion 2213 extending away from the track 11.

[0031] refer to Figure 2 and Figure 4 , Figure 2 This is a top view of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body 21 being pushed into the patch panel body, with the tray body 21 located inside the fiber optic patch panel 100. Figure 4 for Figure 2 An enlarged cross-sectional view of section II is shown below. Figure 2 and Figure 4 As shown, the first through hole 2214 on the first limiting member bracket 221 and the first elastic buckle 1110 of the first limiting part 111 cooperate to achieve a snap-fit ​​connection; Reference Figure 10 , Figure 10 for Figure 7 An enlarged schematic diagram of the damping flipping mechanism removed at point II, as shown below. Figure 10 As shown, at this time, the uppermost tray body 21 is completely pulled out of the fiber optic patch panel, and the first limiting part 111 of the uppermost track 11 is in an unfitted state. The other tray bodies 21 are still located in the fiber optic patch panel 100. The first through hole 2214 and the first elastic buckle 1110 cooperate to achieve a snap-fit. The first protrusion 2211 is located on the hole wall of the first through hole 2214 closest to the last end of the track 11. The orientation of the first protrusion 2211 is the same as that of the first elastic buckle 1110. During the process of the tray body 21 being pulled out in the second direction, the first protrusion 2211 squeezes the first protrusion 1112 of the first elastic buckle 1110. The first protrusion 1112 is compressed to be flush with the surface of the track 11, so that the first elastic buckle 1110 and the first through hole 2214 separate.

[0032] refer to Figure 7 and Figure 8 , Figure 7 This is a three-dimensional structural diagram of a fiber optic patch panel according to one embodiment of the present invention, showing the single-layer tray body being pulled out of the patch panel body. At this time, the uppermost tray body 21 is completely pulled out of the fiber optic patch panel. Figure 8 for Figure 7 An enlarged schematic diagram of point I in the middle, as shown below. Figure 7 and Figure 8As shown, the second through hole 2215 of the first limiting member 22 cooperates with the second elastic buckle 1120 of the second limiting part 112 to achieve a snap-fit, and the second limiting part 112 of the tray body 21 of the other layers that have not moved is still snap-fitted with the second limiting member 23.

[0033] refer to Figure 11 , Figure 11 for Figure 7 An enlarged schematic diagram of section III, as shown below. Figure 11 As shown, except for the top layer, the tray bodies 21 of the other layers did not move, and the second through holes 2215 on the first limiting bracket 211 were in an unfitted state; Reference Figure 8 , Figure 8 for Figure 7 An enlarged schematic diagram of point I in the middle, as shown below. Figure 8 As shown, the second protrusion 2212 is located on the wall of the second through hole 2215 closest to the front end of the track 11. The orientation of the second protrusion 2212 is the same as that of the second elastic buckle 1120. It is used to press the second protrusion 1122 of the second elastic buckle 1120 during the process of pushing the tray body 21 into the fiber optic patch panel 100 in the first direction after it is fully pulled out. The second protrusion 2212 is compressed to be flush with the surface of the track 11, so that the second elastic buckle 1120 and the second through hole 2215 are separated.

[0034] Optionally, when the fiber optic tray 2 is completely separated from the patch panel body 1, it is necessary to install the fiber optic tray 2 with the patch panel body 1. When the independent fiber optic tray 2 is pushed into the track 11 on the patch panel body 1, the third protrusion 2213 is used to squeeze the first protrusion 1112 of the first elastic buckle 1110 and the second protrusion 1122 of the second elastic buckle 1120. The first protrusion 1112 and the second protrusion 1122 are compressed to be flush with the surface of the track 11, making it easier to push in.

[0035] refer to Figure 1-3 , Figure 1 This is a three-dimensional structural diagram of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. At this time, the uppermost tray body 21 is located inside the fiber optic patch panel 100. Figure 2 This is a top view of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. Figure 3 for Figure 2 An enlarged cross-sectional view of point I is shown below. Figure 1-3As shown, the second limiting member 23 includes cavities 231 disposed at the front ends of the two side walls of the pallet body 21. A boss 2311 is disposed within the cavity 231, located at the foremost position within the cavity 231 furthest from the track 11. The boss 2311 does not protrude beyond the outer surface of the side wall of the pallet body 21. (Reference) Figure 3 The cavity 231 and the second elastic latch 1120 of the second limiting member of the uppermost tray body 21 engage to lock the front end of the tray body 21. When the tray body 21 is pulled out along the second direction, the boss 2311 presses against the second protrusion 1122 of the second elastic latch 1120 of the second limiting part 112, thus separating the cavity 231 and the second elastic latch 1120. (Continue to refer to...) Figure 1 The unlocking handle 24 is located at the front end of the protrusion 2311 of the second limiting member 23 and is connected to the second limiting member 23. The protrusion 2311 can move within the cavity 231 via the unlocking handle. When the tray body 2 is pushed into the patch panel body 1 along the first direction, the protrusion 2311 contacts and presses the second elastic buckle 1120. The second elastic buckle 1120 is compressed to be flush with the surface of the track 11. The protrusion 2311 passes over the second elastic buckle 1120. After the second elastic buckle 1120 is no longer pressed by the protrusion 2311, it elastically resets and engages with the cavity 231. At the same time, the protrusion 2311 abuts against the second elastic buckle 1120. Figure 3 As shown, the tray body 21 is located inside the fiber optic patch panel 100 at this time. When the tray body 21 is pulled out along the second direction, the boss 2311 presses against the second protrusion 1122 of the second elastic buckle 1120, and the second elastic buckle 1120 is compressed to be flush with the surface of the track 11, and the second elastic buckle 1120 and the cavity 231 separate.

[0036] In some embodiments, the unlocking handle 24 and the second limiting member 23 are integrally formed.

[0039] During the process of pulling the fiber optic patch panel 100 out along the second direction from the tray body 21, i.e. Figure 1 Status Figure 7 The process of state, based on Figure 1 The tray body 21 is located inside the fiber optic patch panel 100. refer to Figure 4 , Figure 4 for Figure 2 An enlarged cross-sectional view of section II is shown below. Figure 4 As shown, when the unlocking handle 24 is pulled along the second direction, the first protrusion 2211 of the first limiting member 22 first squeezes the first protrusion 1112 of the first elastic buckle 1110 of the first limiting part 111. The first protrusion 1112 undergoes elastic deformation and is compressed to be flush with the surface of the track 11. The first elastic buckle 1110 and the first through hole 2214 of the first limiting member are disengaged. refer to Figure 3 , Figure 3 for Figure 2 An enlarged cross-sectional view of point I is shown below. Figure 3 As shown, the boss 2311 of the second limiting member 23 moves in the second direction and presses the second protrusion 1122 of the second elastic buckle 1120. The second protrusion 1122 also undergoes elastic deformation and is compressed to be flush with the surface of the track 11. The second elastic buckle 1120 and the cavity 231 of the second limiting member 23 disengage. Then the tray body 21 continues to move, see reference. Figure 7 , Figure 7 This is a three-dimensional structural diagram of a single-layer tray body pulled out from the main body of the patch panel, which is one embodiment of the fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. The second protrusion 2212 of the first limiting member 22 contacts and presses the first protrusion 1112 of the first elastic buckle 1110, so that the second protrusion 2212 passes over the first elastic buckle 1110 and the tray body continues to move forward.

[0040] After the pallet body 21 continues to move, the first protrusion 2211 contacts and presses the second protrusion 1122 of the second elastic buckle 1120 of the second limiting part 112, so that the first protrusion 2211 passes the second elastic buckle 1120 and the pallet body continues to move forward. Afterwards, refer to Figure 8 , Figure 8 for Figure 7 An enlarged schematic diagram of point I in the middle, as shown below. Figure 8 As shown, the tray body 21 moves until the second protrusion 2212 of the first limiting member 22 and the second elastic buckle 1120 of the second limiting part 112 come into contact. The second protrusion 2212 presses against the second protrusion 1122 of the second elastic buckle 1120, and the second protrusion 1122 undergoes elastic deformation and is compressed to be flush with the surface of the track 11. The second protrusion 2212 passes over the second protrusion 1122 of the second elastic buckle 1120, and the second protrusion 1122 of the second elastic buckle 1120 elastically resets and contacts the second through hole 2215, realizing the engagement of the second elastic buckle 1120 and the second through hole 2215. At this time, the tray body 21 is completely pulled out of the fiber optic patch panel 100, as shown. Figure 7 As shown.

Figure 7 Status Figure 1 The process of state, based on Figure 7 The tray body 21 is fully extended out of the fiber optic patch panel 100: refer to Figure 8 , Figure 8 for Figure 7 An enlarged schematic diagram of point I in the middle, as shown below. Figure 8 As shown, when the unlocking handle 24 is pulled along the first direction, the second protrusion 2212 of the first limiting bracket 221 presses the second protrusion 1122 of the second elastic buckle 1120, and the second protrusion 1122 undergoes elastic deformation and is compressed to be flush with the surface of the track 11. refer to Figure 7 , Figure 7 This is a three-dimensional structural diagram of a single-layer tray body pulled out from the patch panel body, one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays according to the present invention. Figure 7 As shown, the tray body 21 then continues to move along the first direction, and the third protrusion 2213 and the second protrusion 2212 of the first limiting bracket 221 successively press against the first protrusion 1112 of the first elastic buckle 1110; Reference Figure 4 , Figure 4 for Figure 2 An enlarged cross-sectional view of section II is shown below. Figure 4 As shown, until the first protrusion 2211 contacts the first protrusion 1112 of the first elastic buckle 1110, the first protrusion 2211 presses against the first protrusion 1112 of the first elastic buckle 1110, and the first protrusion 1112 undergoes elastic deformation and is compressed to be flush with the surface of the track 11. The first protrusion 2211 passes over the first protrusion 1112 of the first elastic buckle 1110, and the first protrusion 1112 of the first elastic buckle 1110 elastically resets and contacts the first through hole 2214, realizing the engagement of the first elastic buckle 1110 and the first through hole 2214. At this time, the tray body 21 is located inside the fiber optic distribution frame 100, as shown. Figure 1 As shown.

[0042] The first limiting member 22 and the second limiting member 23 in this embodiment have simple structures. When pushing the tray body 21 into the patch panel body 1 and pulling the tray body 21 out, it is only necessary to pull the unlocking handle 24. The operation is simple, convenient and labor-saving. This application has made reasonable designs on the orientation and position of the first protrusion 2211, the second protrusion 2212, the third protrusion 2213, the first elastic buckle 1110 and the second elastic buckle 1120, so that the process is smooth.

[0043] In some implementations, reference Figure 2 and Figure 6 , Figure 2 This is a top view of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. Figure 6 This is an exploded view of the first damping hinge mechanism of one embodiment of a fiber optic distribution frame for locking and unlocking fiber optic trays according to the present invention, as shown below. Figure 2 and Figure 6As shown, the damping flipping mechanism 25 includes a first damping hinge mechanism 251 and a second damping hinge mechanism 252. The first damping hinge mechanism 251 includes a first hinge 2511, a second hinge 2512, and a damper 2513. Both the first hinge 2511 and the second hinge 2512 have through holes. The damper 2513 passes through the through holes on the first hinge 2511 and the second hinge 2512 and is connected to the first hinge 2511 and the second hinge 2512. The structure of the second damping hinge mechanism 252 is the same as that of the first damping hinge mechanism 251.

[0044] refer to Figure 6 , Figure 6 This is an exploded view of the first damping hinge mechanism of one embodiment of a fiber optic distribution frame for locking and unlocking fiber optic trays according to the present invention, as shown below. Figure 6 As shown, the damper 2513 includes a fixed part 2514 and a rotating part 2515. The fixed part 2514 passes through the through hole of the first hinge 2511, and the first hinge 2511 is fixedly connected to the first limiting member 22. The rotating part 2515 passes through the through hole of the second hinge 2512, and the second hinge 2512 is fixedly connected to one end of the tray body 21. The tray body 21 flips with the rotating part 2515. (Reference) Figure 2 , Figure 2 This is a top view of one embodiment of a fiber optic patch panel for locking and unlocking fiber optic trays, showing the tray body being pushed into the patch panel body. Figure 2 As shown, the two ends of the first damping hinge mechanism 251 are respectively connected to one end of the pallet body 21 and the first limiting bracket 221, and the two ends of the second damping hinge mechanism 252 are respectively connected to the other end of the pallet body 21 and the second limiting bracket 222.

[0045] This embodiment uses a damping flipping mechanism 25 to ensure that when the tray body 21 is fully pulled out of the fiber optic distribution frame 100, i.e. Figure 7 As shown, at this time, simply press down on the tray body 21 to flip the tray body 21 downwards.

[0046] In this embodiment, the first limiting part 111 and the second limiting part 112 on the track 11 cooperate with the first limiting member 22 and the second limiting member 23 of the optical fiber tray 2, respectively, to achieve dual locking of the rear end and the front end of the tray body 21. During unlocking, pulling the unlocking handle 24 in the direction of pulling out the tray body 21 simultaneously releases the lock and moves the tray body 21, thus completing the operation in a single step and improving efficiency. Furthermore, through the cooperation of the second limiting part 112 and the first limiting member 22, the tray body 21 is completely pulled out of the patch panel body 1 and limited. At this point, simply pressing the tray body 21 gently allows the tray body 211 to flip downwards via the damping flipping mechanism 25. The damping flipping mechanism 25 provides damping buffer during the flipping of the tray body 21, preventing instantaneous impacts on the optical fiber tray 2 and the devices on it.
