Description

Technical Field

[0001] The present application relates to the field of data transmission, and in particular to a cabinet. Background Art

[0002] The cabinet is used to install the transmission medium, which may be an optical fiber line, for transmitting data. Since the cabinet size has a unified standard, the scope for installing the optical fiber line in the cabinet is limited. Summary of the invention

[0003] In view of this, it is necessary to provide a cabinet that can increase the scope of installing optical fiber lines while keeping the size unchanged.

[0004] The embodiment of the present application provides a cabinet, comprising a cabinet body, the cabinet further comprising a bracket, the bracket comprising a connecting frame and two retractable adjustment components. One end of each of the adjustment components is connected to the connecting frame, and the other end of each of the adjustment components is rotatably connected to the cabinet, and the adjustment components change the relative position between the connecting frame and the cabinet body by retracting.

[0005] In the cabinet of the above embodiment, when the cabinet is transported, the adjustment component is retracted to the shortest state, and the bracket is rotated so that it is located inside the cabinet, so as to reduce the space occupied by the entire cabinet and allow multiple cabinets to be stacked, thereby achieving high space utilization. When the cabinet is equipped with a transmission medium, the adjustment component can be rotated so that the connecting frame extends out of the cabinet, thereby increasing the installation space of the transmission medium. Since the transmission medium needs to be bent and extend out of the cabinet, and the material of the transmission medium includes glass, when the transmission medium is excessively bent or even bent, it will cause damage to the transmission medium. By increasing the installation space, there can be enough space to organize and install the transmission medium, and the curvature of the bending of the transmission medium can be reduced to reduce the occurrence of damage to the transmission medium.

[0006] In at least one embodiment, the cabinet is provided with a mounting groove, one end of the adjustment component is rotatably connected to the cabinet, and the connecting frame can be rotated between a first position and a second position through the adjustment component. When the connecting frame is in the first position, it is located in the mounting groove, and when the connecting frame is in the second position, it is located outside the mounting groove.

[0007] In the cabinet of the above embodiment, the installation groove is provided to provide a position for installing the adjustment component and to allow at least a portion of the optical fiber connected to the connecting frame to extend vertically into the cabinet.

[0008] In at least one embodiment, the adjustment component includes a rotating part, a sliding part and a limiting part. One end of the rotating part is rotatably connected to the cabinet. The sliding part is slidably connected to the rotating part so that the adjustment component can be telescopically adjusted along its own extension direction, and one end of the sliding part is connected to the connecting frame. The limiting part is arranged on the sliding part and is positioned so that when the sliding part slides to a preset position relative to the rotating part, the limiting part and the rotating part are limitedly matched.

[0009] In the cabinet of the above embodiment, the connection frame can be switched between the storage state and the extended state by rotating the rotating part. The sliding part can slide relative to the rotating part to control the overall length of the adjustment assembly. The relative position of the sliding part and the rotating part can be limited by the limiting cooperation between the limiting part and the rotating part to ensure the stable position of the adjustment assembly.

[0010] In at least one embodiment, the rotating part is provided with a mating groove, and the limiting part includes a blocking block. When the sliding part slides to a preset position relative to the rotating part, the blocking block extends into the mating groove so that the blocking block and the rotating part are limitedly mated. The limiting part is configured to be able to elastically deform away from the rotating part so that the blocking block is separated from the mating groove.

[0011] In the cabinet of the above embodiment, the relative position of the rotating part and the sliding part is limited by the cooperation between the clamping block and the cooperation slot, so that the adjustment component can maintain the longest state or the shortest state.

[0012] In at least one embodiment, the limiting portion further includes an elastic connecting plate and an operating plate. One end of the elastic connecting plate is connected to the sliding portion, and the clamping block is disposed at the other end of the elastic connecting plate. The operating plate is disposed on the elastic connecting plate and can drive the elastic connecting plate to elastically deform away from the rotating portion so that the clamping block is separated from the matching groove.

[0013] In the cabinet of the above embodiment, by applying external force to the operation panel, the operation panel drives the elastic connection plate, and the elastic connection plate undergoes elastic deformation so that the card block is separated from the matching groove, thereby releasing the limit between the sliding part and the rotating part. When the external force is removed, the elastic deformation of the elastic connection plate is restored so that the card block can return to the matching groove. The elastic deformation of the elastic connection plate can automatically extend the card block into the matching groove, making the operation more simple and quick.

[0014] In at least one embodiment, the operating plate is disposed at one end of the elastic connecting plate close to the clamping block, and the operating plate is inclined relative to the elastic connecting plate.

[0015] In the cabinet of the above embodiment, the elastic connection plate can be elastically deformed by pulling or pressing the operation plate, so that the clamping block is separated from the matching groove.

[0016] In at least one embodiment, the sliding part is slidably connected to the limiting part so that the sliding part extends out of the limiting part or retracts into the limiting part. The block is provided with a guide surface, and along the extending direction of the sliding part, the guide surface approaches the elastic connecting plate.

[0017] In the cabinet of the above embodiment, when the overall length of the adjustment assembly is at the shortest state and the block is located in the matching groove close to the rotating groove, the sliding part slides in the extension direction, the guide surface contacts the groove wall of the matching groove, and the groove wall of the matching groove applies a component force in the direction away from the rotating part to the guide surface, so that the end of the elastic connecting piece provided with the block is elastically deformed, so that as the sliding part slides, the block can be separated from the matching groove. When the overall length of the adjustment assembly is at the longest, the end of the block away from the guide surface is at a right angle and contacts the groove wall corresponding to the matching groove to prevent the sliding part from moving in the retracting direction.

[0018] In at least one embodiment, guide positioning blocks are provided on opposite sides of the rotating part, and the sliding part is located between the two guide positioning blocks. Guide rails are provided on opposite sides of the sliding part, and the rotating part is located between the two guide rails, and when the guide positioning blocks abut against the guide rails, the sliding part can be prevented from extending outward.

[0019] In the cabinet of the above embodiment, the cooperation between the guide rail and the guide positioning block can not only play a guiding role, but also a positioning role, so that when the adjustment component reaches the longest state, it can prevent the sliding part from continuing to slide, causing the sliding part to separate from the rotating part.

[0020] In at least one embodiment, the sliding portion includes a first sliding plate and a second sliding plate. The two guide rails are arranged on the first sliding plate. The second sliding plate is located between the first sliding plate and the rotating portion, one end of the second sliding plate is connected to one end of the connecting frame, and the limiting portion is connected to the second sliding plate.

[0021] In the cabinet of the above embodiment, the sliding plate includes a separable first sliding plate and a second sliding plate, which can be made of different materials to meet the design requirements and reduce costs.

[0022] In at least one embodiment, the adjustment assembly also includes a positioning portion, which is arranged on the rotating portion. When the positioning portion abuts against the sliding portion, it can block the sliding portion from moving in a retracting direction. The positioning portion is configured to be able to move in a second direction relative to the rotating portion to abut against the cabinet body, thereby limiting the rotation of the rotating portion.

[0023] In the cabinet of the above embodiment, the positioning part can not only block the sliding part from sliding in the retracting direction to prevent the sliding part from separating from the rotating part, but also abut the cabinet body to limit the rotation of the rotating part, so that the connecting frame can stably maintain the extended state or the stored state.

[0024] In the cabinet of the present application, by rotating the bracket relative to the cabinet, the installation range of the optical fiber line in the third direction can be increased while keeping the size of the cabinet and the size of the installation slot unchanged, so as to reduce the bending curvature of the optical fiber line. By setting the length of the adjustment component to be adjustable, the maximum number of brackets installed in the installation slot can be increased, thereby increasing the maximum number of optical fiber lines that can be installed while keeping the size of the cabinet and the installation slot unchanged.

[0076] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0077] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0078] When two elements (planes, lines) are arranged in parallel, it should be understood that the relationship between the two elements includes parallel and approximately parallel. Approximately parallel should be understood as a certain angle between the two elements, which is greater than 0° and less than or equal to 10°.

[0079] When two elements (planes, lines) are arranged vertically, it should be understood that the relationship between the two elements includes vertical and approximately vertical. The approximately vertical should be understood as the angle between the two elements being greater than or equal to 80° and less than 90°.

[0080] When a parameter is greater than, equal to, or less than a certain endpoint value, it should be understood that the endpoint value is allowed to have a tolerance of ±10%. For example, if the ratio of A to B is greater than 10, it should be understood to include the case where the ratio of A to B is greater than 9, and also include the case where the ratio of A to B is greater than 11.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0082] Some embodiments of the present application provide a cabinet, including a cabinet body, the cabinet further including a bracket, the bracket including a connecting frame and two retractable adjustment components. One end of each of the adjustment components is connected to the connecting frame, and the other end of each of the adjustment components is rotatably connected to the cabinet, and the adjustment components change the relative position between the connecting frame and the cabinet body by retracting.

[0083] In the cabinet of the above embodiment, when the cabinet is transported, the adjustment component is retracted to the shortest state, and the bracket is rotated so that it is located in the cabinet body, so as to reduce the space occupied by the entire cabinet and allow multiple cabinets to be stacked, with high space utilization. When the cabinet is equipped with a transmission medium, the adjustment component can be rotated so that the connecting frame extends out of the cabinet, which can increase the installation space of the transmission medium. Since the transmission medium needs to be bent and extended out of the cabinet, and the material of the transmission medium includes glass, when the transmission medium is excessively bent or even bent, it will cause damage to the transmission medium. By increasing the installation space, there can be enough space to organize and install the transmission medium, and the curvature of the bending of the transmission medium can be reduced to reduce the occurrence of damage to the transmission medium.

[0084] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0085] See also Figure 1 One embodiment of the present application provides a cabinet 001, which includes a cabinet body 100 and a plurality of brackets 200. The plurality of brackets 200 are arranged in the cabinet 001 at intervals. The plurality should be understood as a number including one or more. The transmission medium is at least partially located in the cabinet body 100 and connected to the brackets 200. The transmission medium includes but is not limited to twisted pair cables, coaxial cables or optical fiber cables 300 (such as Figure 5 The embodiment of the present application takes the optical fiber line 300 as an example of the transmission medium.

[0086] In order to more clearly describe the cabinet 001 of each embodiment of the present application, Figure 1The coordinate system is established in the following. The subsequent description of the various positions of cabinet 001 is based on this coordinate system. Figure 1 , the first direction X is parallel to the X-axis, the width of the cabinet 001 extends along the first direction X, and the plurality of brackets 200 are arranged at intervals along the first direction X. The Y-axis is perpendicular to the X-axis in the horizontal plane, the second direction Y is parallel to the Y-axis, and the length of the cabinet 001 extends along the second direction Y. The Z-axis is perpendicular to the plane formed by the X-axis and the Y-axis, the third direction Z is parallel to the Z-axis, and the height of the cabinet 001 extends along the third direction Z. In the description of this application, the terms "above", "below", "upward", and "downward" are all relative to the third direction Z.

[0087] It is understandable that the above-mentioned coordinate system is established for the convenience of describing the various embodiments of the present application, and the directions of the length, width and height of the cabinet 001 are not limited. For example, the width of the cabinet 001 can also extend along the second direction Y, and the length can extend along the first direction X.

[0088] See also Figure 1 and Figure 2 Each bracket 200 includes a connecting frame 10 and two adjustment components 20. The connecting frame 10 is provided with a plurality of assembly grooves 11, and the assembly grooves 11 are used to connect with the connector 301, and one end of the optical fiber line 300 is connected with the connector 301. The two adjustment components 20 are arranged in the cabinet 100 at intervals along the second direction Y, and are located at opposite ends of the connecting frame 10. One end of the adjustment component 20 is connected to the connecting frame 10, and the other end is rotatably connected to the cabinet 001, and the rotation axis of the adjustment component 20 extends along the second direction Y, so that the connecting frame 10 can rotate between the first position and the second position. When the connecting frame 10 is located in the first position, it is in a storage state, and when the connecting frame 10 is located in the second position, it is in an extended state. When the connecting frame 10 is in the storage state, it can be arranged in the cabinet 001. When the connecting frame 10 is in the extended state, it can extend out of the cabinet 001, and the adjustment component 20 is configured to be retractable along its own extension direction to adjust the length.

[0089] By rotating the adjustment assembly 20 and the cabinet 100 , the connection frame 10 can be placed in a storage state, in which the connection frame 10 is disposed in the cabinet 100 , or in an extended state, in which the connection frame 10 is extended out of the cabinet 100 .

[0090] When transporting the cabinet 001, the connecting frame 10 can be arranged in the cabinet 100, so that the six directions of the cabinet 001 are not protruding, so that multiple cabinets 001 can be stacked and arranged, and the space utilization rate is high. The connecting frame 10 is arranged in the cabinet 100, which can also reduce the situation that the bracket 200 is accidentally collided with when the cabinet 001 is transported, causing the bracket 200 to be skewed and damaged. When the cabinet 001 is equipped with the optical fiber line 300, the adjustment component 20 can be rotated to make the connecting frame 10 extend out of the cabinet 100, so that the installation space of the optical fiber line 300 in the third direction Z can be increased. Since the optical fiber line 300 needs to be bent and extend out of the cabinet 100, and the material of the optical fiber line 300 includes glass, when the optical fiber line 300 is excessively bent or even bent, it will cause the optical fiber line 300 to be damaged. By increasing the installation space, there can be enough space to organize and install the optical fiber line 300, and the curvature of the bending of the optical fiber line 300 can be reduced to reduce the situation of damage to the optical fiber line 300.

[0091] The adjusting component 20 can be extended and retracted along its own extension direction to adjust the length. When the connecting frame 10 is in the storage state, the adjusting component 20 adjusts the length along the first direction X. When the connecting frame 10 is in the extended state, the adjusting component 20 adjusts the length along the third direction Z. When the connecting frame 10 is arranged in the cabinet 100, the length of the adjusting component 20 can be reduced to the shortest state. At this time, the length of the adjusting component 20 in the first direction X is small, so that when the size of the cabinet 100 is fixed, multiple brackets 200 arranged at intervals along the first direction X can be installed as much as possible. When the connecting frame 10 is extended out of the cabinet 100, the length of the adjusting component 20 can be extended to the longest state. At this time, the length of the adjusting component 20 in the third direction Z is long, and the installation space of the optical fiber line 300 in the third direction Z is large, so as to facilitate the installation of the optical fiber line 300.

[0092] The cabinet 100 includes a top plate 101, a side plate 102 and a bottom plate 103. The top plate 101 and the bottom plate 103 are arranged horizontally and spaced apart along the third direction Z. The side plate 102 is arranged vertically, and one end of the side plate 102 is connected to the top plate 101, and the other end is connected to the bottom plate 103. The top plate 101 is located between the connecting frame 10 in the first position and the connecting frame 10 in the second position, so that the connecting frame 10 can be arranged in the top plate 101 when it is in the first position. Optionally, the number of side plates 102 is four, and they are arranged in a rectangular array at the corners of the bottom plate 103, so that the cabinet 100 is hollowed out around the horizontal direction to facilitate the arrangement of the optical fiber lines 300.

[0093] Optionally, in some embodiments, the top plate 101 is provided with a mounting groove 101a, and the mounting groove 101a penetrates the top plate 101 along the third direction Z, and one end of the adjustment component 20 is rotatably connected to the groove wall of the mounting groove 101a. When the connecting frame 10 is located at the first position, the connecting frame 10 can be located in the mounting groove 101a, and when the connecting frame 10 is located at the second position, it can extend out of the mounting groove 101a. By providing the mounting groove 101a, it is possible to provide a position for installing the adjustment component 20, and at least part of the optical fiber line 300 connected to the connecting frame 10 can be vertically extended into the cabinet 100. It can be understood that the adjustment component 20 is not limited to being connected to the groove wall of the mounting groove 101a, and can also be other, such as a connecting piece is provided on the upper surface of the top plate 101, the connecting piece faces the mounting groove 101a, and the adjustment component 20 is rotatably connected to the connecting piece.

[0094] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The adjustment assembly 20 includes a rotating portion 21, a sliding portion 22 and a limiting portion 23. One end of the rotating portion 21 is rotatably connected to the cabinet 100 and the rotation axis extends along the second direction Y, so that the other end of the rotating portion 21 can be rotated to the outside of the installation groove 101a. The sliding portion 22 is slidably connected to the rotating portion 21, so that the adjustment assembly 20 can be telescopically adjusted in its own extension direction. One end of the sliding portion 22 is connected to the connecting frame 10. The limiting portion 23 is provided on the sliding portion 22 and is positioned so that when the sliding portion 22 slides to a preset position relative to the rotating portion 21, the limiting portion 23 is limitedly matched with the rotating portion 21.

[0095] By rotating the rotating part 21, the connecting frame 10 can be driven to switch between the storage state and the extended state. When the connecting frame 10 is in the storage state, the adjusting assembly 20 is located in the installation groove 101a as a whole, and there will be no protrusions on the plane of the top plate 101, which can be convenient for stacking and carrying, and can effectively reduce the damage of the adjusting assembly 20 due to collision. When the connecting frame 10 is in the extended state, it can be located outside the installation groove 101a, thereby increasing the installation space of the optical fiber line 300 in the third direction Z, so as to facilitate the installation of the optical fiber line 300 and reduce the bending curvature of the optical fiber line 300. The sliding part 22 is slidably connected to the rotating part 21, and can control the overall length of the adjusting assembly 20, so as to control the length of the adjusting assembly 20 to the minimum when the connecting frame 10 is in the storage state, and control the length of the adjusting assembly 20 to the maximum when the connecting frame 10 is in the extended state. Figure 3 As shown, it is a related technical solution, in which the adjustment component 20 is an integrated structure and cannot be adjusted in length. There are four brackets 200 in the installation slot 101a. Figure 2 As shown, Figure 2 This is a technical solution in an embodiment of the present application, in which the sliding portion 22 slides relative to the limiting portion 23 to control the length of the adjustment assembly 20. While keeping the size of the installation slot 101a unchanged and the height of the connecting frame 10 unchanged when in the extended state, six brackets 200 can be arranged in the installation slot 101a, and the number of brackets 200 is increased by 50%, that is, in the cabinet 001 of the same size, the number of connectable optical fiber lines 300 is increased by 50%.

[0096] Optionally, in some embodiments, a rotating hole 211 is provided at one end of the rotating part 21, and the rotating hole 211 penetrates the rotating part 21 along the second direction Y, so that the rotating part 21 can be connected to the groove wall of the installation groove 101a through the rotating shaft 214, so that the rotating part 21 can rotate relative to the cabinet 100.

[0097] Optionally, in some embodiments, the rotating part 21 is provided with a mating groove 212, and the limiting part 23 includes a block 231. When the sliding part 22 slides to a preset position relative to the rotating part 21, the block 231 extends into the mating groove 212 so that the block 231 and the rotating part 21 are limitedly engaged. The limiting part 23 is configured to be able to elastically deform away from the rotating part 21 so that the block 231 is separated from the mating groove 212.

[0098] The block 231 cooperates with the matching groove 212 to define the relative position of the rotating part 21 and the sliding part 22, so that the adjustment assembly 20 can maintain the longest state or the shortest state. Since the adjustment assembly 20 is in a vertical setting when the connecting frame 10 is in the extended state, the sliding part 22 and the rotating part 21 slide along the third direction Z. Therefore, when the sliding frame is subjected to the gravity of the connecting frame 10 and the optical fiber line 300 located on the connecting frame 10, the rotating part 21 is easily retracted, and the block 231 is used to block the movement of the sliding frame to reduce the activity of the optical fiber line 300, resulting in unstable connection or excessive bending of the optical fiber line 300.

[0099] Optionally, there are two matching grooves 212, and the two matching grooves 212 and the rotating groove are spaced apart along the length direction of the rotating block. The preset position of the sliding part 22 is the position when the adjustment component 20 is in the longest state and the shortest state.

[0100] It is understandable that the limiting part 23 is not limited to the block 231 and the matching groove 212 to limit the relative position of the sliding part 22 and the rotating part 21, and can also be other ways, such as the sliding part 22 and the rotating part 21 are both provided with holes at corresponding positions, and the limiting part 23 is a columnar structure, such as a bolt, a pin, etc., which is penetrated through the holes of the sliding part 22 and the rotating part 21 to limit the positions of the two. For another example, the limiting part 23 is a magnet that attracts each other and is correspondingly arranged on the sliding part 22 and the rotating part 21.

[0101] See also Fig. 9 and Fig.10 Optionally, in some embodiments, the limiting portion 23 further includes an elastic connecting plate 232 and an operating plate 233. The elastic connecting plate 232 extends along the length direction of the adjusting assembly 20, one end of the elastic connecting plate 232 is connected to the sliding portion 22, and the block 231 is disposed at the other end of the elastic connecting plate 232. The operating plate 233 is disposed on the elastic connecting plate 232, and can drive the elastic connecting plate 232 to elastically deform away from the rotating portion 21, so that the block 231 is separated from the matching groove 212.

[0102] By applying an external force to the operating plate 233, the operating plate 233 drives the elastic connecting plate 232, and the elastic connecting plate 232 undergoes elastic deformation so that the block 231 is separated from the matching groove 212, thereby releasing the limit between the sliding part 22 and the rotating part 21. When the external force is removed, the elastic deformation of the elastic connecting plate 232 is restored so that the block 231 can return to the matching groove 212. The elastic deformation of the elastic connecting plate 232 can allow the block 231 to automatically extend into the matching groove 212, making the operation more convenient and quick.

[0103] Optionally, in some embodiments, the sliding portion 22 is slidably connected to the limiting portion 23, so that the sliding portion 22 extends out of the limiting portion 23 or retracts into the limiting portion 23. The block 231 is provided with a guide surface 2311, and along the extending direction of the sliding portion 22, the guide surface 2311 approaches the elastic connecting plate 232. When the overall length of the adjustment assembly 20 is in the shortest state, and the block 231 is located near the matching groove 212 of the rotating groove, the sliding portion 22 slides in the extending direction, and the guide surface 2311 contacts the groove wall of the matching groove 212, and the groove wall of the matching groove 212 applies a component force to the guide surface 2311 in the direction away from the rotating portion 21, so that the end of the elastic connecting plate provided with the block 231 undergoes elastic deformation, so that as the sliding portion 22 slides, the block 231 can be separated from the matching groove 212. When the overall length of the adjustment assembly 20 is at its longest, the end of the block 231 away from the guide surface 2311 is at a right angle and contacts the corresponding groove wall of the matching groove 212 to prevent the sliding portion 22 from moving in the retracting direction.

[0104] In practical applications, the limiting portion 23 is mainly used to prevent the sliding portion 22 from sliding downward due to the gravity of the connecting frame 10, the connecting frame 10 and the optical fiber line 300 when the connecting frame 10 is in the extended state and the adjusting assembly 20 is in the longest state. Secondly, it is used to prevent the sliding frame from sliding due to shaking during transportation when the connecting frame 10 is in the storage state and the adjusting assembly 20 is in the shortest state. Since the inertia caused by gravity is larger than that caused by shaking, when the adjusting assembly 20 is in the longest state, it is necessary to maintain better stability to ensure that the sliding portion 22 will not retract. When the adjusting assembly 20 is in the shortest state, there is no need to limit the sliding portion 22 too strongly so that the sliding portion 22 can extend out of the rotating portion 21.

[0105] Optionally, the number of the clamping blocks 231 is two, and the two clamping blocks 231 are arranged at intervals on both sides of one end of the elastic connecting plate 232 .

[0106] Optionally, in some embodiments, the operating plate 233 is disposed at one end of the elastic connecting plate 232 close to the block 231, and the operating plate 233 is inclined relative to the elastic connecting plate 232. The operating plate 233 exerts a large force arm on the elastic connecting plate 232, and the elastic connecting plate 232 is more likely to deform.

[0107] Optionally, in some embodiments, along the sliding direction of the sliding portion 22, the operating plate 233 is inclined in a direction away from the sliding portion 22. Applying a pulling force in a direction away from the rotating portion 21 to the operating plate 233 can cause the elastic connecting plate 232 to produce elastic deformation, so that the block 231 is separated from the matching groove 212. By pulling the operating plate 233 to release the limit of the sliding portion 22, the operation process is simple and convenient.

[0108] Optionally, in some embodiments, the sliding portion 22 is provided with an avoidance groove 2211 , and the limiting portion 23 is disposed in the avoidance groove 2211 , so that the blocking block 231 can extend into different matching grooves 212 of the rotating portion 21 .

[0109] In some embodiments, the limiting portion 23 and the sliding portion 22 are detachably connected. Specifically, one end of the elastic connecting plate 232 away from the block 231 is fixed to the sliding portion 22 by a fastener 223. The fastener 223 can be a bolt, a rivet or the like.

[0110] See also Figure 8 In other embodiments, the limiting portion 23 and the sliding portion 22 are integrally formed. Specifically, one end of the elastic connecting plate 232 away from the block 231 is integrally formed with the sliding portion 22 .

[0111] The sliding portion 22 includes a first sliding plate 221 and a second sliding plate 222. The first sliding plate 221, the second sliding plate 222 and the rotating portion 21 are stacked. The second sliding plate 222 is located between the first sliding plate 221 and the rotating portion 21. The avoidance groove 2211 is located on the first sliding plate 221, and the shape of the first avoidance groove 2211 is adapted to the shape of the elastic connecting plate 232, and the first sliding plate 221 is slidably connected to the rotating portion 21.

[0112] One end of the second sliding plate 222 is connected to one end of the connecting frame 10, and the limiting portion 23 is connected to the second sliding plate 222. The second sliding plate 222 is provided with a through hole 2221 at a corresponding position, so that the block 231 can extend into the matching groove 212 through the through hole 2221. Optionally, when the limiting portion 23 is detachably connected to the sliding portion 22, the end of the elastic connecting plate 232 away from the block 231 is bent toward the second sliding plate 222, so that the elastic connecting plate 232 can extend into the positioning groove 2222 of the second sliding plate 222 to achieve rough positioning. When the limiting portion 23 and the sliding portion 22 are an integrated structure, the end of the elastic connecting plate 232 away from the block 231 can be integrally connected to the second sliding plate 222, or integrally connected to the first sliding plate 221.

[0113] See also Fig.11 The sliding part 22 includes a separable first sliding plate 221 and a second sliding plate 222, which can be made of different materials to meet the design requirements and reduce costs. For example, the first sliding plate 221 is made of metal material such as aluminum alloy, and the second sliding plate 222 is made of rubber. The first sliding plate 221 is made of metal with better strength, which can reduce the damage to the sliding plate. The second sliding plate 222 is made of rubber, which can reduce weight and cost, and the second sliding plate 222 is in direct contact with the rotating part 21, which can reduce the friction between the second sliding plate 222 and the rotating part 21, resulting in wear of the rotating part 21.

[0114] Optionally, in some embodiments, guide positioning blocks 213 are provided on two opposite sides of the rotating portion 21 , and the sliding portion 22 is located between the two guide positioning blocks 213 .

[0115] Guide rails 2212 are provided on opposite sides of the first sliding plate 221 of the sliding part 22, and the rotating part 21 is located between the two guide rails 2212. When the guide positioning block 213 abuts against the guide rails 2212, the sliding part 22 can be prevented from extending outward. The cooperation between the guide rails 2212 and the guide positioning block 213 can not only play a guiding role, but also play a positioning role, so that when the adjustment component 20 reaches the longest state, the sliding part 22 can be prevented from continuing to slide, resulting in the separation of the sliding part 22 and the rotating part 21.

[0116] See also Fig.12Optionally, in some embodiments, the adjustment assembly 20 further includes a positioning portion 24, which is disposed on the rotating portion 21. When the positioning portion 24 abuts against the sliding portion 22, the sliding portion 22 can be blocked from moving in the retracting direction. The positioning portion 24 is configured to be able to move relative to the rotating portion 21 in the second direction Y to abut against the cabinet 100, thereby limiting the rotation of the rotating portion 21. The positioning portion 24 can not only block the sliding portion 22 from sliding in the retracting direction, but also prevent the sliding portion 22 from separating from the rotating portion 21. The positioning portion 24 abuts against the cabinet 100 to limit the rotation of the rotating portion 21, so that the connecting frame 10 can stably maintain the extended state or the stored state.

[0117] Optionally, the positioning portion 24 is threadedly connected to the rotating portion 21 , so that the positioning portion 24 can pass through the rotating portion 21 and can also move along the second direction Y relative to the rotating portion 21 .

[0118] See also Fig.13 and Fig.14 Optionally, in some other embodiments, another adjustment assembly 20a is provided, the adjustment assembly 20a includes a rotating portion 21a, a sliding portion 22a and a limiting portion 23a, the sliding portion 22a includes a first sliding plate 221a and a second sliding plate 222a, and the limiting portion 23a is integrally formed with the first sliding plate 221a. The difference between the adjustment assembly 20a and the adjustment assembly 20 is mainly that the position of the rotating portion 21a is interchanged with the position of the first sliding plate 221a and the limiting portion 23a, and the structure of the limiting portion 23 is different from that of the limiting portion 23a.

[0119] Specifically, the rotating portion 21a is located on one side of the second sliding plate 222a away from the connecting frame 10, and the first sliding plate 221a and the limiting portion 23a are located on the other side of the second sliding plate 222a.

[0120] The limiting portion 23a includes a pressing block 231a and an elastic connecting plate 232a. One end of the elastic connecting plate 232a is connected to the first sliding plate 221a, and the other end is connected to the pressing block 231a. Along the retraction direction of the first sliding plate 221a, the elastic connecting plate 232b gradually tilts toward the rotating portion 21a, so that the pressing block 231a can extend into the through hole 2221a and the matching groove 212a to limit the relative sliding. By applying pressure to the pressing block 231a, the pressing block 231a is separated from the through hole 2221a and the matching groove 212a, so that the sliding portion 22a and the limiting portion 23a can slide relative to the rotating portion 21a. The pressing block 231a guides the surface 2311a so that when the sliding portion 23a slides upward, it is not necessary to press the pressing block 231a. The shape of the matching groove 212a located at the top is larger than the shape of the pressing block 231a, so that when the user presses the pressing block 231a with a finger, part of the finger can extend into the matching groove 212a, thereby improving the user's comfort and user experience.

[0121] Since the internal space of the cabinet 001 is small, the number of optical fiber lines 300 is large, the arrangement is dense, and the optical fiber lines 300 cannot be bent significantly, the method of controlling the length of the adjustment components 20, 20a should be as simple as possible and occupy as little space as possible. The limit of the sliding part 22a is released by pressing the pressing block 231a, which is not only easy to operate and labor-saving, but also when the pressing block 231a is pressed, the pressing block 231a moves toward the connecting frame 10, which does not increase the occupied space, and the pressing block 231a will not be blocked by the optical fiber lines 300, resulting in the situation that the pressing block 231a cannot move.

[0122] In summary, the use process of the cabinet 001 in the embodiment of the present application is as follows: the bracket 200 is rotated to rotate the connecting frame 10 from the storage state to the extended state, and the positioning portion 24 is rotated to make the positioning portion 24 abut against the cabinet 001 to limit the rotation of the rotating portion 21. An upward pulling force is applied to the connecting frame 10 to make the sliding portion 22 extend out of the rotating portion 21, and the block 231 is extended into the matching groove 212 to limit the movement of the sliding portion 22, and then the optical fiber line 300 is installed.

[0123] By rotating the bracket 200 relative to the cabinet 100, the installation range of the optical fiber 300 in the third direction Z can be increased while keeping the size of the cabinet 100 and the size of the installation slot 101a unchanged, so as to reduce the bending curvature of the optical fiber 300. By setting the length of the adjustment component 20 to be adjustable, the maximum number of brackets 200 installed in the installation slot 101a can be increased, thereby increasing the maximum number of optical fiber lines 300 that can be installed while keeping the size of the cabinet 100 and the installation slot 101a unchanged.

[0124] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
