[0033] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0034] First refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a fiber optic distribution frame including an unlocking assembly 100 according to some embodiments of the present disclosure is shown, wherein a portion of the housing of the distribution frame is removed to clearly illustrate the structure of the unlocking assembly 100. Figure 2 Shows Figure 1 An enlarged view of part A in the figure. The unlocking assembly 100 is used to lock and release a component to be locked. The unlocking assembly 100 includes a locking block 20 and a locking mechanism 10. The locking block 20 is configured to be able to move relative to the component to be locked along a first direction, and the locking mechanism 10 and the component to be locked are limited relative to each other in the first direction, but can move relative to each other in a second horizontal direction perpendicular to the first direction. A positioning groove 21 is provided on the locking block 20, and at least two surfaces that are relatively inclined and arranged in a V shape along the first direction are provided in the positioning groove 21, which are defined as a first inclined surface 23 and a second inclined surface 24. The locking mechanism 10 is configured to include an elastic member having elasticity in the second direction and a positioning member abutted by one end of the elastic member, and at least a portion of the positioning member can elastically extend out of the locking block 20 along the second direction to be locked. When the locking block 20 moves along the first direction, at least a portion of the positioning member contacts either the first inclined surface 23 or the second inclined surface 24 , and is pushed by the first inclined surface 23 or the second inclined surface 24 to retract the locking block 20 along the second direction to unlock.

[0035] It should be noted that the first direction is preferably the length direction of the unlocking component 100 , and the second direction is the width direction of the unlocking component 100 .

[0036] Reference Figure 2 In this embodiment, the locking block 20 is provided with a long strip-shaped fixing groove 22 extending along the first direction, and a fixing seat 42 also formed in a long strip shape is arranged in the fixing groove 22, and the fixing seat 42 is used to be fixedly connected with the part to be locked. In this embodiment, the part to be locked is a support plate 40, and two unlocking components 100 are both arranged on the support plate 40 along the first direction, and are respectively arranged at the two ends of the support plate 40 along the second direction. The length of the fixing seat 42 along the first direction is smaller than the fixing groove 22, and the width of the fixing seat 42 is roughly consistent with the fixing groove 22, so that the locking block 20 and the fixing seat 42 can move relative to each other along the first direction, but cannot or almost cannot move relative to each other along the second direction. Two guide rails 30 are respectively arranged on the outer side of the unlocking component 100 along the second direction, and the part to be locked can move relative to the guide rails 30 along the first direction. The guide rails 30 are provided with a first locking groove 34 and a second locking groove 35 formed by being recessed along the second direction. The two unlocking components 100 of the guide rail 30 and the support plate 40 cooperate to ensure that the support plate 40 moves along the first direction. When the positioning member elastically extends out of the locking block 20 and is located in the first locking groove 34 or the second locking groove 35, the position of the support plate 40 relative to the guide rail 30 is fixed.

[0037] See also Figure 5 , Figure 5The schematic diagram of the combined state of the limit seat 41 and the locking mechanism 10 of the disclosed embodiment is shown. The limit seat 41 is also provided with a limit groove 411 for limiting the locking mechanism 10. The limit groove 411 extends along the second direction, one end of which passes through the limit seat 41, and the other end terminates in the limit seat 41 and forms a vertical stop surface 412 at the termination point. The locking mechanism 10 is at least partially arranged in the limit groove 411, and is limited in the first direction by the limit groove 411, and can only move relative to the limit seat 41 in the second direction. Specifically, in this embodiment, the locking mechanism 10 includes a spring 12 and a positioning member 11 arranged in sequence along the second direction, one end of the spring 12 abuts against the stop surface 412 of the limit groove 411 along the second direction, and the other end abuts against the positioning member 11 along the second direction, so that the positioning member 11 can be subjected to the elastic force of the spring 12 when being pushed in the second direction. The positioning member 11 includes a positioning portion 112 protruding from the limiting groove 411 in the vertical direction, and a positioning pin 111 arranged and protruding in the opposite direction to the spring 12 in the second direction. The positioning portion 112 of the positioning member 11 is used to drive the positioning member 11 to move along the limiting groove 411 toward the spring 12 when it abuts against one of the first inclined surface 23 and the second inclined surface 24, so that the positioning pin 111 retracts and releases the lock. When one of the first inclined surface 23 and the second inclined surface 24 is released from the abutment, the positioning member 11 is pushed by the elastic force of the spring 12, and the positioning portion 112 moves to the top of the V-shaped arrangement formed by the first inclined surface 23 and the second inclined surface 24 to be maintained, while the positioning pin 111 extends along the second direction to achieve locking. In this embodiment, the two side edges of the limiting groove 411 along the first direction are formed as oblique edges, so that the cross section of the limiting groove is formed into a trapezoidal shape with a wide bottom and a narrow top, and the part of the positioning member 11 accommodated in the limiting groove 411 is also formed into a shape with a trapezoidal cross section matching therewith. Thus, the positioning member 11 and the limiting groove 411 are configured to be slidably connected in a shape-fitting manner, and are also limited in the vertical direction, so that the locking action is more stable and reliable. It can be understood by those skilled in the art that the present disclosure does not limit the cross-sectional shapes of the positioning groove and the positioning member, as long as they can satisfy the requirement of forming a limit in the first direction.

[0038] Refer again Figure 2In this embodiment, the positioning groove 21 on the locking block 20 is roughly set to a triangle, which includes an inner surface extending along the first direction and two inner surfaces inclined relative to each other, and the two inclined inner surfaces are defined as a first inclined surface 23 and a second inclined surface 24, and the positioning portion 112 can at least partially extend into the positioning groove 21. The locking block 20 is provided with an opening on the side along the second direction, and the positioning pin 111 of the positioning member 11 can extend from the opening when it is in the locked state. By setting the length of the limiting groove 411, it can be ensured that when the locking block 20 retracts along the second direction under the action of an external force, the positioning pin 111 of the locking mechanism 10 can be completely retracted from the side opening of the locking block 20. The positioning portion 112 is also formed with an arc contact surface, which is used to keep the direction of the force at the contact point perpendicular to the arc surface direction when contacting with the first inclined surface 23 or the second inclined surface 24, reduce friction, and make the relative sliding smooth to avoid jamming.

[0039] Those skilled in the art will appreciate that in this embodiment, the positioning groove is formed into a triangle with first and second hypotenuses, but the present disclosure is not limited in this respect. For example, a locking groove with a polygonal shape may also be provided, or the first or second hypotenuse may be provided with a slight arc, as long as it can ensure good relative sliding with the positioning member and push it to move along the second direction.

[0040] Figure 6 The diagram shows the combined state of the fixing seat 42 and the fixing seat spring 43 of some embodiments of the present disclosure. The fixing seat 42 includes an open guide opening 45 arranged at one end thereof along the first direction, and the guide opening 45 completely penetrates the fixing seat 42 along the second direction. A spring positioning hole 44 arranged along the first direction is also arranged at the center of the guide opening 45, and the fixing seat spring 43 is arranged in the spring positioning hole 44.

[0041] Figure 7The guide rail 30 of some embodiments of the present disclosure is shown. Among them, the guide rail 30 includes three groups of guide rail limiting mechanisms arranged in the vertical direction, each group of guide rail limiting mechanisms includes a first locking groove 34 and a second locking groove 35 open toward the limiting seat 41, and the first locking groove 34 and the second locking groove 35 are arranged at intervals along the first direction. The first locking groove 34 includes a vertical end face (vertical to the first direction and parallel to the second direction), which is defined as a first locking surface 341. The first locking groove 34 also includes an inclined guide surface 342 opposite to the first locking surface 341, and the guide surface 342 forms a transition slope that gradually approaches the surface of the guide rail 30 in a direction away from the first locking surface 341. The transition slope is used to make the positioning pin 111 that abuts against it easier to slide and retract when unlocking. The two opposite end faces of the second locking groove 35 are both set as vertical end faces, and the two end faces are located at the two ends of the second locking groove 35 along the first direction and are parallel to the vertical end face of the first locking groove 34. In addition, a mounting groove 36 is further provided on the side of the second locking groove 35 away from the first locking groove 34. The mounting groove 36 is provided at the end of the guide rail along the first direction. The mounting groove 36 includes a mounting slope that gradually penetrates into the guide rail 30 along the direction close to the end of the guide rail. The mounting slope is used to make it easier for the positioning pin 111 that abuts against it to slide and retract when the part to be locked equipped with the unlocking assembly 100 is installed into the guide rail 30. In this embodiment, the guide rail limiting mechanism also includes a quick lock mechanism 37 provided at the end along the first direction. The quick lock mechanism 37 is a conventional quick lock mechanism in the art, which is used to cooperate with an adapting protrusion 28. After the adapting protrusion 28 presses the quick lock mechanism 37 along the first direction, the quick lock mechanism 37 switches between a locking and a releasing state. In addition, in this embodiment, the guide rail 30 includes three groups of guide rail limiting mechanisms, and each group of guide rail limiting mechanisms can cooperate with a stacked unlocking component to perform locking and unlocking actions, but the present disclosure is not limited in this regard, and only one group or other number of guide rail limiting mechanisms can be set to meet different equipment capacity requirements.

[0042] See also Figure 8 and Fig. 9 , Figure 8 A schematic diagram of a tray assembly 200 according to some embodiments of the present disclosure is shown. Fig. 9 Shows Figure 8The sectional view taken along the BB line in the figure. The tray assembly 200 includes a support plate 40 and an unlocking assembly 100 symmetrically arranged on both sides of the support plate 40 along the second direction. The support plate 40 is fixedly connected to two fixing seats 42 and a limiting seat 41 on one side by bolts or the like. The two fixing seats 42 are arranged opposite to each other along the first direction with their guide openings 45 facing each other, so that the fixing seat springs 43 in their spring positioning holes 44 are also arranged opposite to each other. Spring top blocks 29 are arranged in the two fixing grooves 22 of the locking block 20. The two spring top blocks 29 correspond to the guide openings 45 of the two fixing seats 42 and are arranged on the inner walls of the two fixing grooves 22 opposite to each other in the protruding direction. Each spring top block 29 corresponds to the spring positioning hole 44 of a fixing seat 42, so that the fixing seat spring 43 in the guide opening 45 can be aligned with the spring top block 29 in the first direction. Since the spring positioning holes 44 of the two fixed seats 42 are arranged in opposite directions, the two fixed seat springs 43 are pressed against by the spring top block 29 to generate spring elastic forces in opposite directions. Therefore, no matter whether the locking block 20 is pushed or pulled in the first direction, it will be subjected to the spring elastic force in the opposite direction of the movement direction of the locking block 20 relative to the support plate 40. When the locking block 20 is pushed to move in the first direction, the first inclined surface 23 slides relative to the positioning member 11 and pushes the positioning member 11 to retract in the first direction, and a corresponding fixed seat spring 43 of the two fixed seats 42 is compressed. When the push on the locking block 20 is released, the compressed fixed seat spring 43 pushes the locking block 20 to reset, and the positioning member 11 elastically extends; on the contrary, when the locking block 20 is pushed to move in the opposite direction of the moving direction, the other corresponding fixed seat spring 43 of the two fixed seats 42 is compressed. When the push on the sliding block is released, the compressed fixed seat spring 43 pushes the locking block 20 to reset. The locking block 20 also includes an operating portion 27 for pushing or pulling, and the operating portion 27 is arranged at one end of the locking block 20 along the first direction. In addition, the locking block 20 also includes an adapting protrusion 28 protruding along the first direction, such as Figure 2 As shown, the adapting protrusion 28 is used to abut against the quick lock mechanism 37 of the guide rail 30 in the first direction to lock or unlock the guide rail 30. The position of the first locking groove 34 is set to be suitable for accommodating the extended positioning pin 111 when the adapting protrusion 28 is locked to the quick lock mechanism 37.

[0043] The following is combined with Figures 2 to 4 The unlocking process of the unlocking assembly 100 according to some embodiments of the present disclosure is described. Figure 2 In the embodiment, the tray assembly 200 provided with the unlocking assembly 100 along the first direction is located at the first locking position, at which time the locking mechanism 10 is locked in the first locking groove 34, and Figure 3 Shows Figure 2 Schematic diagram showing that after the unlocking assembly 100 is unlocked, the locking mechanism 10 is unlocked and moved out of the first locking groove 34 and moved to the second locking groove 35, Figure 4 Shows Figure 2 Schematic diagram of the locking mechanism 10 of the unlocking assembly 100 being locked in the second locking groove 35, at which time the tray assembly 200 is in the second locking position. When locked in the first locking groove 34, the locking mechanism 10 is acted upon by the elastic force applied by the spring 12 along the second direction, and its positioning portion 112 is pushed toward the outermost tip of the triangular positioning groove 21, i.e., the junction of the first inclined surface 23 and the second inclined surface 24. At the same time, the positioning pin 111 of the locking mechanism 10 extends out from the opening on the side of the locking block 20 along the second direction and is inserted into the first locking groove 34, thereby locking the fixing seat 42 relative to the guide rail 30 along the first direction. When moving from the first locking groove 34 to the second locking groove 35 and unlocking, the locking block 20 is pulled toward the second locking groove 35 and moves relative to the fixing seat 42. At this time, the positioning groove 21 moves relative to the positioning member 11, so that the positioning portion 112 moves away from the tip of the triangular positioning groove 21, and the first inclined surface 23 contacts the positioning portion 112 of the positioning member 11 and slides relative to it, thereby driving the positioning pin 111 of the positioning member 11 to retract along the fixing groove 22 of the fixing seat 42 to overcome the spring elastic force, and finally disengage from the first locking groove 34 to complete unlocking. When the locking block 20 moves to the point where the positioning pin 111 of the positioning member 11 is aligned with the second locking groove 35, the positioning member 11 is driven to pop out by the spring elastic force, and the positioning pin 111 is inserted into the second locking groove 35 to complete locking. Conversely, when the second locking groove 35 is unlocked and moves toward the first locking groove 34, the locking block 20 is pushed toward the first locking groove 34, the positioning groove 21 moves relative to the positioning member 11, and the second inclined surface 24 contacts the positioning member 11 and slides relative to it, so that the positioning pin 111 of the positioning member 11 is disengaged from the second locking groove 35 along the second direction.

[0044] It should be noted that when the tray assembly 200 is located in the second locking position, the tray 40 protrudes out of the guide rail 30 along the first direction, and the unlocking components 100 arranged on both sides of the tray assembly 200 cooperate with the guide rail, and the tray assembly 200 is fixed relative to the guide rail 30. At this time, it is convenient to inspect the components arranged on the tray 40 or assemble accessories on the tray 40; when the tray assembly 200 is located in the first locking position, the adapter protrusion 28 arranged on the tray assembly 200 away from the operating part 27 cooperates with the quick locking mechanism 37 of the guide rail 30 to lock the tray assembly 200. The tray assembly 200 will not move relative to the guide rail 30 without the action of external force, which is convenient for transportation and improves the stability of use.

[0045] Fig.10 and Fig.11A wiring rack provided by some embodiments of the present disclosure is shown, and the wiring rack includes a bottom shell 52, an upper shell 50, a cover plate 51 and a front door 54, which together enclose a storage space, and at least one tray assembly 200 according to one of the embodiments of the present disclosure is arranged in the storage space. The guide rail 30 is installed inside the bottom shell 52 through the mounting plate 56. Each tray assembly 200 can be pulled outward from the openable front door 54 along a first direction to perform operations such as installation and removal of its internal components or wiring. It can be understood that when it is necessary to perform installation, disassembly, wiring or other operations on the internal components of the tray assembly 200, the tray assembly 200 is continued to be pushed along the first direction away from the side of the operating portion 27, so that the adaptor protrusion 28 of the tray assembly 200 is disengaged from the quick lock mechanism 37 of the guide rail 30, and then the tray assembly 200 is pulled along the first direction toward the side of the operating portion 27 until the tray assembly is in the second locking position, and the cover 51 is removed to expose the operating position on the tray assembly 200. At this time, the tray assembly 200 is relatively fixed, which is convenient for the operator to perform installation and disassembly operations.

[0046] According to the unlocking assembly of the embodiment of the present disclosure, the locking mechanism cooperates with the corresponding positioning groove that moves relative to the locking mechanism, and can easily lock and unlock the part to be locked through simple pushing and pulling actions. In addition, due to the elasticity provided by the first elastic member of the locking mechanism, the object to be locked can be more stably maintained in its locked position, and has a certain resistance to vibration and impact, thereby enhancing the stability of the system.

[0047] Although multiple embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art may think of many changes, modifications, and alternatives without departing from the thought and spirit of the present disclosure. It should be understood that in the process of practicing the present disclosure, various alternatives to the embodiments of the present disclosure described herein may be adopted.
