Description

Technical Field

[0001] This invention relates to the field of track-mounted fiber optic tray technology, and more specifically to a track-mounted fiber optic tray structure that can be quickly assembled and disassembled. Background Technology

[0002] Currently, the fiber optic communication components of power distribution automation systems all utilize fixed fiber optic tray racks. These racks consist of fiber optic trays that terminate the optical fibers and mounting brackets for securing and supporting them. After entering the substation, the optical fiber passes through a cable trench from the bottom up into the communication or automation cabinet, is secured to the cabinet with cable ties, and then terminates with the fiber optic tray, completing the connection between the optical fiber and the tray.

[0003] Because the fiber optic tray rack is fixedly installed inside the communication cabinet or automation cabinet, when it is necessary to replace the equipment in the substation or other related equipment, it is impossible to completely remove the fiber optic cable and the fiber optic tray rack from the back. The fiber optic cable and the tray can only be removed by cutting the fiber optic cable. The new station needs to install the tray and re-terminate it, which wastes the cost and time of equipment replacement and causes unnecessary extension of the construction period. Summary of the Invention

[0004] In view of this, the problem to be solved by the present invention is to provide a quick-disassembly and assembly track-type fiber optic tray rack structure, which enables quick disassembly and installation of the fiber optic tray rack.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A quick-assembly and disassembly track-type fiber optic tray rack structure includes a support mechanism for fixing and supporting the left or right end of the fiber optic tray. The support mechanism includes a horizontally arranged first support plate, which is slidably engaged with the side wall of the cabinet via a first groove and a slider. The end face of the suspended end of the first support plate is provided with an internal threaded groove whose side wall communicates with the top surface of the first support plate. A clamping block with its upper end protruding from the top surface of the first support plate is screwed into the threaded groove for pressing the left or right side wall of the fiber optic tray.

[0006] Furthermore, the clamping block has an elastically deformable buffer on the side facing the fiber optic tray.

[0007] Furthermore, the support mechanism includes a second support plate disposed above the first support plate and fixedly connected to the first support plate, wherein the structure of the second support plate is mirror-symmetrical to the structure of the first support plate.

[0008] Furthermore, the first slide is fixedly connected to the side wall of the cabinet via a base plate, and the top surface of the base plate is provided with a locking mechanism located in front of the first slide for fixing the front end of the slider.

[0009] Furthermore, the locking mechanism includes a deformable plate with a gap between it and the base plate. The deformable plate has an outwardly convex structure. An upper locking plate and a lower locking plate are respectively tightly attached to the upper and lower ends of the deformable plate facing the slider. The front end of the slider is provided with a locking protrusion that is opposite to the middle section of the deformable plate, so as to transform the convex structure of the deformable plate into a concave structure.

[0010] Furthermore, the opposite ends of the upper and lower locking plates are both attached to the middle section of the deformable plate, and the opposite ends of the upper and lower locking plates are respectively attached to the upper and lower ends of the deformable plate.

[0011] Furthermore, the protrusion height of the locking protrusion gradually increases from back to front.

[0012] Furthermore, compressible elastic elements are sandwiched between the upper end of the deformable plate and the bottom plate, and between the lower end of the deformable plate and the bottom plate.

[0013] Furthermore, sliding grooves that can engage with the upper and lower ends of the slider are provided on the opposite surfaces of the first support plate and the second support plate.

[0014] Furthermore, the length of the threaded groove is between one-half and three-quarters of the width of the support mechanism.

[0015] The beneficial effects of this invention are: By setting two opposing first support plates inside the cabinet to stably support the fiber optic tray, and by adjusting the position of the clamping blocks on the first support plates to fix or remove the fiber optic tray, it is easy to quickly disassemble the fiber optic tray with the fiber optic cable and remove it from the back of the cabinet. When updating the cabinet, there is no need to cut the fiber optic cable, saving equipment update costs and update time. Attached Figure Description

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is described as "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is described as "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed terms.

[0020] This invention provides a quick-assembly and disassembly track-type fiber optic tray structure, such as... Figure 1 and Figure 2As shown, the cabinet 1 includes a frame for mounting fiber optic trays 2. The cabinet 1 includes a left wall and a right wall, and each of the opposite surfaces of the left and right walls is provided with a bracket mechanism 3 for fixing and supporting both ends of the fiber optic trays 2. The bracket mechanism 3 includes a horizontally arranged first support plate 304. The first support plate 304 is slidably engaged with the side wall of the cabinet 1 through a first sliding groove 5 and a slider 303, so as to horizontally fix the first support plate 304 to the left and right walls of the cabinet 1.

[0021] The end face of the suspended end of the first support plate 304 has an internal threaded groove that communicates with the top surface of the first support plate 304. A clamping block 302 is screwed into the threaded groove, and the upper end of the clamping block 302 extends out of the top surface of the first support plate 304. When fixing the fiber optic tray 2, the suspended ends of the first support plate 304 on the left and right walls support the left and right ends of the fiber optic tray 2. The screwing position of the clamping block 302 and the threaded groove is adjusted (the clamping block 302 moves along the length of the threaded groove) so that the upper end of the clamping block 302 presses against the left and right side walls of the fiber optic tray 2, thus clamping and fixing the fiber optic tray 2.

[0022] The clamping block 302 has an elastically deformable buffer 322 on the side facing the fiber optic tray 2. When the clamping block 302 presses against the side wall of the fiber optic tray 2, the buffer 322 is compressed. The reaction force of the buffer 322 can increase the pressure between the clamping block 302 and the threaded groove, thereby improving the stability of the position between the clamping block 302 and the threaded groove (the clamping block 302 is not easy to move when external vibration occurs).

[0023] Since the location of the cable trench in the power distribution room cannot be changed, when cabinet 1 needs to be replaced, if the optical fiber is not cut, the optical fiber tray 2 must be removed from the rear of cabinet 1. In this solution, since the optical fiber tray 2 is only clamped and fixed by the clamping block 302, it can be quickly removed by manually adjusting the position of the clamping block 302, and the optical fiber tray 2 can be removed from the rear of cabinet 1.

[0024] like Figure 7 As shown, the clamping block 302 includes a cylindrical buffer member 322. A circular groove with an annular structure is formed in the middle section of the side wall of the buffer member 322. A circular clamping ring 321 with an annular structure is provided within the groove. The outer side wall of the clamping ring 321 has an external thread that engages with the internal thread groove. Both ends of the buffer member 322 extend beyond the ends of the clamping ring 321. When the elasticity of one end of the buffer member 322 fails, the other end can continue to be used after changing the installation direction of the buffer member 322, thus extending the service life of the clamping block 302.

[0025] One embodiment of this application is: the minimum outer diameter of the clamping ring 321 is not less than the maximum outer diameter of the buffer 322, so as to avoid friction between the buffer 322 and the internal thread groove, which would affect the service life of the buffer 322.

[0026] The support mechanism 3 includes a second support plate 301 disposed above and fixedly connected to the first support plate 304. The structure of the second support plate 301 is mirror-symmetrical to that of the first support plate 304. In use, the clamping block 302 on the first support plate 304 clamps the lower edge of the side wall of the fiber optic tray 2, and the clamping block 302 on the second support plate 301 clamps the upper edge of the side wall of the fiber optic tray 2, which can effectively improve the installation stability of the fiber optic tray 2. One embodiment of this application is as follows: Figure 6 As shown, the end face of the first support plate 304 or the second support plate 301 at its suspended end is provided with a threaded groove that connects the sidewall to both the top and bottom surfaces. The upper and lower ends of the clamping block 302 extend out of the top and bottom surfaces of the first support plate 304, respectively, increasing the force-bearing area of ​​the clamping block 302. When the gap between the first support plate 304 and the second support plate 301 is small, the position of the clamping block 302 can be adjusted by the force-bearing area below the first support plate 304 and above the second support plate 301.

[0027] One embodiment of this application is as follows: Figure 5 and Figure 6 As shown, the first support plate 304 is provided with several threaded grooves along its width direction to improve the stability of the fiber optic tray 2 during installation.

[0028] like Figure 3 and Figure 4 As shown, the first slide 5 is fixedly connected to the side wall of the cabinet 1 via the base plate 6. The top surface of the base plate 6 is provided with a locking mechanism 4 located in front of the first slide 5, which is used to clamp the front end of the slider 303. The first slide 5 cooperates with the slider 303 to improve the installation stability of the support mechanism 3. The locking mechanism 4 is used to fix the front end of the slider 303, thereby fixing the support mechanism 3.

[0029] like Figure 2 As shown, the locking mechanism 4 includes a deformable plate 401 with a gap between it and the base plate 6. The deformable plate 401 has an outward convex structure. The upper and lower ends of the deformable plate 401 facing the slider are respectively tightly attached to the upper locking plate 402 and the lower locking plate. The slider 303 has a locking protrusion 331 at one end (front end) near the front of the cabinet 1, which is opposite to the middle section of the deformable plate 401. The locking protrusion 331 can transform the outward convex structure of the deformable plate 401 into an inward concave structure, so that the distance between the opposite ends of the upper locking plate 402 and the lower locking plate is reduced and they are closer to the base plate 6, thereby clamping and fixing the front end of the slider 303.

[0030] Compressible elastic elements 403 are sandwiched between the upper end and the base plate 6, and between the lower end and the base plate 6, creating a gap between the deformable plate 401 and the base plate 6, providing sufficient space for the concave middle section of the deformable plate 401. The distance between the deformable plate 401 and the slider 303 and the base plate 6 can also be adjusted by compressing the elastic elements 403, allowing the deformable plate 401 to return to its convex structure, facilitating the disassembly of the support mechanism 3.

[0031] One embodiment of this application is as follows: when the locking mechanism 4 is not in use, the outward convex structure of the deformable plate 401 drives the upper locking plate 402 and the lower locking plate to move away from the base plate 6, increasing the distance between the upper locking plate 402 and the lower locking plate, so as to avoid affecting the movement of the slider 303.

[0032] When installing slider 303, the end of slider 303 near the back of cabinet 1 (rear end) is placed between upper locking plate 402 and lower locking plate. Due to the convex structure of deformable plate 401, the distance between upper locking plate 402 and lower locking plate is increased, making the distance between upper locking plate 402 and lower locking plate greater than the height of slider 303. This does not affect the engagement of slider 303 with the first slide groove 5 behind locking mechanism 4.

[0033] When the slider 303 is tightened, when the locking protrusion 331 at the front end of the slider 303 moves to a position opposite to the deformable plate 401, the outward convex structure of the deformable plate 401 changes to an inward concave structure. During the deformation process of the deformable plate 401, the distance between the opposite ends of the upper locking plate 402 and the lower locking plate gradually decreases and moves closer to the base plate 6, so as to apply a force towards the base plate 6 on the slider 303 and fix the slider 303.

[0034] When removing the slider 303, press the upper and lower ends of the deformable plate 401 to bring it closer to the base plate 6 and away from the locking protrusion 331 of the slider 303. Based on the squeezing force of the base plate 6 on the deformable plate 401 and the interaction force between the slider 303 and the second slide groove, the middle section of the deformable plate 401 is restored to an outward convex structure, and the distance between the upper locking plate 402 and the lower locking plate increases, making it easier for the slider 303 to be removed from the first slide groove 5.

[0035] The upper locking plate 402 and the lower locking plate each have a second groove on their opposite surfaces that respectively mate with the top and bottom ends of the slider 303. This increases the contact area with the slider 303 and improves the fixing efficiency of the slider 303. In one embodiment of this application, when both the top and bottom ends of the slider 303 are convex semi-circular arc structures, the left side of the second groove is a horizontal structure, and the left side of the second groove is a quarter-circular arc structure with the left side lower than the right side.

[0036] The opposite ends of the upper locking plate 402 and the lower locking plate are both attached to the middle section of the deformable plate 401. The opposite ends of the upper locking plate 402 and the lower locking plate are respectively attached to the upper and lower ends of the deformable plate 401 to adjust the sensitivity of the distance between the upper locking plate 402 and the lower locking plate. When the middle section of the deformable plate 401 is slightly concave (the locking protrusion 331 is not opposite to the deformable plate 401), a gap is formed between the opposite ends of the upper locking plate 402 and the lower locking plate and the deformable plate 401 (the opposite ends of the upper locking plate 402 and the lower locking plate do not move), so as to avoid affecting the normal sliding of the slider 303. When the middle section of the deformable plate 401 is concave to a certain extent (the locking protrusion 331 is opposite to the deformable plate 401), the deformable plate 401 drives the upper locking plate 402 and the lower locking plate to move closer to each other and press the bottom end of the slider 303 to complete the fixation of the slider 303.

[0037] One embodiment of this application is as follows: when the locking protrusion 331 is not aligned with the deformable plate 401, the middle section of the deformable plate 401 will form a slight indentation (the slider 303 squeezes the middle section of the deformable plate 401). The protrusion height of the locking protrusion 331 gradually increases from back to front, that is: the closer to the front of the cabinet 1, the higher the height of the locking protrusion 331. The gap generated by the slight indentation allows the locking protrusion 331 to move smoothly to the position opposite to the deformable plate 401, reducing the probability of jamming when installing the bracket mechanism 3.

[0038] The first support plate 304 and the second support plate 301 each have a sliding groove 305 on their opposite surfaces at their suspended ends, which can engage with the slider 303. When the updated cabinet 1 is too wide, the width of the first support plate 304 and the second support plate 301 can be increased by engaging the sliding groove 305 with the slider 303 of the new support mechanism 3, so that the fiber optic tray 2 can be installed into a new cabinet 1 of any size.

[0039] One embodiment of this application is that the length of the threaded groove is between one-half and three-quarters of the width of the support mechanism 3, so that the fluctuation range of the clamping distance between two opposing support mechanisms 3 is greater than the width of one support mechanism 3.

[0040] One embodiment of this application is as follows: The fiber optic tray 2 has sliders 303 at both ends that engage with the first sliding groove 5. The protrusion height of the locking protrusion 331 at the front end of the slider 303 gradually increases and then decreases from back to front, facilitating that the front end of the slider 303 can slide into the corresponding position of the deformable plate 401 from the front side of the locking mechanism and from the rear side of the locking mechanism. During the replacement of a cabinet of the same size, the fiber optic tray 2 is directly removed from the rear of the old cabinet and then directly installed from the rear of the new cabinet. In this embodiment, the bottom surface of the first sliding groove 5 is provided with a third sliding groove to facilitate the passage of the locking protrusion 331.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
