Description

Technical Field

[0001] The utility model belongs to the technical field of OLT devices. Specifically, it particularly relates to a novel heat dissipation structure for an OLT device. Background Technique

[0002] The OLT device is an important central office device. The functions it realizes are: being connected to the front-end switch with a network cable, converting into an optical signal, and interconnecting with the splitter at the user end with a single optical fiber to realize functions such as control, management, and ranging of the ONU device at the user end. The OLT device, like the ONU device, is also an optoelectronic integrated device.

[0003] In the Chinese Patent Network CN215268570U, a heat dissipation type boxed OLT switching device is disclosed, including an OLT switching device body. A plurality of heat dissipation holes are opened on both sides of the OLT switching device body. A plurality of interfaces are opened on the side of the OLT switching device body. Heat dissipation components are provided on both sides of the OLT switching device body. The heat dissipation components include two frames, which are respectively fixedly arranged on both sides of the OLT switching device body. Filters are fixedly arranged on the outer sides of the inner walls of the two frames, and heat dissipation fans are fixedly installed on the inner sides of the two filters.

[0004] The silica gel dryer can adsorb the moisture contained in the passing air flow. At the same time, the electric heating plate can dry the silica gel dryer and enable the silica gel desiccant to be recycled. The silica gel desiccant can then be reused, and the prerequisite is that it must be baked at a high temperature (generally 180 degrees Celsius) to bake out all the moisture that the product has absorbed and saturated and then reused. It is very difficult for the electric heating plate itself to reach this temperature. Therefore, when the silica gel desiccant absorbs saturated moisture, it still needs to be replaced. Due to the obstruction of the frame, it is relatively inconvenient to replace the silica gel desiccant; when inserting the connector into the interface, it is necessary to first expand the corresponding two limiting plates, and then make the connector penetrate the sliding groove and connect with the interface. During this process, the two limiting plates cannot be loosened. Since the limiting plates are arranged inside the sliding seat, it is relatively difficult to expand the two limiting plates, resulting in relatively inconvenient insertion of the connector into the interface.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0006] In view of the problems in the related art, the utility model proposes a novel heat dissipation structure for an OLT device to overcome the above-mentioned technical problems existing in the existing related art.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a novel heat dissipation structure for an OLT device, which comprises an OLT device body. Installation frames are fixedly connected to both sides of the OLT device body. A placement groove is formed in the bottom inner wall of the installation frame, and the placement groove penetrates through the top of the installation frame. A storage component is arranged inside the placement groove, and a fixing component is arranged on the top of the installation frame. A mounting plate is fixedly installed on one side of the installation frame, and a guiding column is fixedly connected to one side of the mounting plate. A clamping component is movably connected to the outer surface of the guiding column.

[0009] Further, the storage component comprises a bottom plate, which is movably connected to the placement groove. A bent filter box is fixedly connected to the top of the bottom plate, and a plurality of bent filter boxes are arranged in an array on the top of the bottom plate.

[0010] Further, the fixing component comprises a T-shaped plate, which is movably connected to the placement groove. The bottom of the T-shaped plate is in contact with the top of the bent filter box. A fixing groove is formed in one side of the T-shaped plate, and a fixing plate is movably connected to the inside of the fixing groove. A limiting frame is fixedly connected to the top of the installation frame, and the fixing plate is movably connected to the limiting frame. Limiting blocks are fixedly connected to the left and right sides of the fixing plate.

[0011] Further, the fixing component further comprises a magnetic strip, which is fixedly connected to the front side of the fixing plate. A handle is fixedly connected between the rear side of the fixing plate and the top of the T-shaped plate. A glass plate is arranged inside the T-shaped plate.

[0012] Further, heat dissipation grooves are formed on both sides of the OLT device body. A filter screen is fixedly connected to the inner wall of the installation frame, and a fan is fixedly installed on the bottom inner wall of the installation frame.

[0013] Further, an interface is formed on the front surface of the OLT device body. Two guiding columns are symmetrically arranged up and down, and the interface is located between the two guiding columns.

[0014] Further, the clamping component comprises a first clamping plate, which is movably connected to the guiding column. A clamping groove is formed in one side of the first clamping plate, and a clamping block is clamped in the clamping groove. A second clamping plate is fixedly connected to one side of the clamping block, and the second clamping plate is movably connected to the guiding column. Wire holes are formed in the front surfaces of the first clamping plate and the second clamping plate, and grooves are formed in the top and bottom of the first clamping plate and the second clamping plate.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model pulls the fixing plate and moves the front side of the fixing plate out of the inside of the fixing groove. Then, the T-shaped plate is pulled upward so that the T-shaped plate no longer presses the folded filter box. Next, the folded filter box is pinched and lifted upward, so that the folded filter box and the bottom plate are directly moved out of the inside of the installation frame through the placement groove. Then, the silica gel desiccant inside the folded filter box is poured out and the new silica gel desiccant is poured into the inside of the folded filter box. In summary, when replacing the silica gel desiccant inside the folded filter box, the fixing plate is directly pulled outward, and then the T-shaped plate is moved out of the top of the folded filter box, and the folded filter box can be moved out of the inside of the installation frame, so that it is more convenient to replace the silica gel desiccant inside the folded filter box.

[0017] 2. When the utility model inserts the connector into the inside of the interface, the first clamping plate and the second clamping plate are pulled through the groove and separated from each other. After the connector is inserted into the inside of the interface, the first clamping plate and the second clamping plate are directly moved so that the clamping block on the second clamping plate is clamped into the inside of the clamping groove on the first clamping plate. At the same time, the wire holes on the first clamping plate and the second clamping plate are directly sleeved on the outside of the wire behind the connector, so that the connector will not move out of the inside of the interface. In summary, when the connector is inserted into the inside of the interface, the first clamping plate and the second clamping plate are directly separated through the groove, and then it is not necessary to pull the two clamping plates when the connector is inserted into the inside of the interface later, so that it is more convenient to insert the connector into the inside of the interface.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationships are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.

[0032] Please refer to Figures 1 - 8As shown in the figure, the utility model is a new heat dissipation structure for an OLT device, including an OLT device body 1. Both sides of the OLT device body 1 are fixedly connected with mounting frames 2. A placement groove 3 is opened at the bottom of the inner wall of the mounting frame 2. The placement groove 3 penetrates through the top of the mounting frame 2. A storage component 4 is arranged inside the placement groove 3. A fixing component 5 is arranged at the top of the mounting frame 2. One side of the mounting frame 2 is fixedly installed with a mounting plate 6. One side of the mounting plate 6 is fixedly connected with a guiding column 7. A clamping component 8 is movably connected to the outer surface of the guiding column 7.

[0033] Silica gel desiccant is placed inside the storage component 4. At this time, the moisture in the air flow flowing through the inside of the mounting frame 2 is adsorbed by the silica gel desiccant inside the storage component 4. When the silica gel desiccant is about to reach saturation, the fixing component 5 is directly moved so that the fixing component 5 no longer limits the storage component 4. As a result, the storage component 4 can drive the nearly saturated silica gel desiccant to move out of the inside of the mounting frame 2 through the placement groove 3. Then, the silica gel desiccant inside the storage component 4 is replaced. After the connector of the external wire is connected to the OLT device body 1, the clamping component 8 can clamp the wire behind the connector.

[0034] By moving the fixing component 5, the fixing component 5 no longer limits the storage component 4. At this time, the storage component 4 containing silica gel desiccant moves out of the inside of the mounting frame 2 through the placement groove 3, making it convenient to replace the silica gel desiccant inside the storage component 4. After the connector is connected to the OLT device body 1, the clamping component 8 can be moved so that the clamping component 8 clamps the wire behind the connector. This setting enables the clamping component 8 to limit the connector so that the connector does not move backward, and only the clamping component 8 needs to be moved when clamping the wire, making the whole operation relatively convenient.

[0035] In one embodiment, for the above-mentioned storage component 4, the storage component 4 includes a bottom plate 401. The bottom plate 401 is movably connected with the placement groove 3. A bent filter box 402 is fixedly connected to the top of the bottom plate 401. A plurality of bent filter boxes 402 are arranged in an array on the top of the bottom plate 401.

[0036] Pulling the bent filter cartridge 402 can move the bent filter cartridge 402 out of the interior of the mounting frame 2 of the bottom plate 401. Since the top of the bent filter cartridge 402 is not blocked, the silica gel desiccant inside the bent filter cartridge 402 can be directly poured out, making it more convenient to replace the silica gel desiccant. When the bent filter cartridge 402 moves into the interior of the mounting frame 2, the bottom plate 401 at the bottom of the bent filter cartridge 402 directly moves into the placement groove 3 at the bottom of the inner wall of the mounting frame 2. This setting ensures the stability of the bent filter cartridge 402 inside the mounting frame 2. At the same time, the shape of the bent filter cartridge 402 allows the flowing air to pass through the bent filter cartridge 402 for a longer time, enabling the silica gel desiccant inside the bent filter cartridge 402 to better adsorb the moisture in the air.

[0037] In one embodiment, for the above-mentioned fixing component 5, the fixing component 5 includes a T-shaped plate 501. The T-shaped plate 501 is movably connected to the placement groove 3. The bottom of the T-shaped plate 501 is in contact with the top of the bent filter cartridge 402. A fixing groove 502 is formed on one side of the T-shaped plate 501. An fixing plate 503 is movably connected inside the fixing groove 502. A limiting frame 504 is fixedly connected to the top of the mounting frame 2. The fixing plate 503 is movably connected to the limiting frame 504. Limiting blocks 505 are fixedly connected to the left and right sides of the fixing plate 503.

[0038] When moving the bent filter cartridge 402 out of the interior of the mounting frame 2, directly move the fixing plate 503. At this time, the fixing plate 503 moves linearly under the limitation of the limiting frame 504. When the front side of the fixing plate 503 moves out of the interior of the fixing groove 502, directly pull the T-shaped plate 501 upward and make the T-shaped plate 501 move out of the placement groove 3 at the top of the mounting frame 2. At the same time, the T-shaped plate 501 no longer presses the bent filter cartridge 402. Under the limitation of the contact with the bent filter cartridge 402, only need to pull the fixing plate 503 and then lift the T-shaped plate 501 upward. The whole operation is relatively convenient. At the same time, the setting of the limiting blocks 505 prevents the fixing plate 503 from randomly disengaging from the interior of the limiting frame 504.

[0039] In one embodiment, for the above-mentioned fixing component 5, the fixing component 5 further includes a magnetic strip 506. The magnetic strip 506 is fixedly connected to the front side of the fixing plate 503. A handle 507 is fixedly connected between the rear side of the fixing plate 503 and the top of the T-shaped plate 501. A glass plate 508 is arranged inside the T-shaped plate 501.

[0040] Through the glass plate 508, the silica gel desiccant inside the bent filter cartridge 402 can be inspected, and it can be judged whether the silica gel desiccant can be used continuously by its color. When pulling the fixing plate 503 and the T-shaped plate 501, the corresponding handle 507 can be used. When the fixing plate 503 moves into the fixing groove 502, the magnetic strip 506 is directly adsorbed to the inner wall of the fixing groove 502. This setting makes it so that without the influence of a large external force, the fixing plate 503 will not move out of the fixing groove 502 randomly, so that the fixing plate 503 can better limit the T-shaped plate 501 through the fixing groove 502.

[0041] In one embodiment, for the above OLT device body 1, heat dissipation grooves 9 are provided on both sides of the OLT device body 1, a filter screen 10 is fixedly connected to the inner wall of the installation frame 2, and a fan 11 is fixedly installed at the bottom of the inner wall of the installation frame 2.

[0042] The fan 11 can extract the external air flow and make the air flow through the filter screen 10 into the installation frame 2. At this time, the air flow passes through the bent filter cartridge 402, and the silica gel desiccant inside the bent filter cartridge 402 adsorbs the moisture in the passing air flow. Then the air flow flows into the OLT device through the heat dissipation grooves 9 and dissipates heat from the internal components. The setting of the filter screen 10 makes the dust in the air flow not flow into the installation frame 2. At the same time, two groups of fans 11 are symmetrically arranged on both sides of the OLT device, and the two groups of fans 11 can work alternately. This setting makes it so that neither of the two groups of fans 11 needs to work under overload.

[0043] In one embodiment, for the above OLT device body 1, an interface 12 is provided on the front of the OLT device body 1, and two guiding columns 7 are symmetrically arranged up and down, and the interface 12 is located between the two guiding columns 7.

[0044] When connecting an external wire to the OLT device body 1, directly insert the connector at one end of the external wire into the interface 12. The setting of the two guiding columns 7 makes it so that there is no obstruction when inserting the connector into the interface 12.

[0045] In one embodiment, for the above clamping assembly 8, the clamping assembly 8 includes a first clamping plate 801, the first clamping plate 801 is movably connected to the guiding column 7, a clamping groove 802 is provided on one side of the first clamping plate 801, a clamping block 803 is clamped in the clamping groove 802, a second clamping plate 804 is fixedly connected to one side of the clamping block 803, the second clamping plate 804 is movably connected to the guiding column 7, wire holes 805 are provided on the front surfaces of the first clamping plate 801 and the second clamping plate 804, and grooves 806 are provided at the top and bottom of the first clamping plate 801 and the second clamping plate 804.

[0046] When inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are pulled through the groove 806, causing them to separate. After inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are directly moved, causing the latch 803 on the second clamping plate 804 to snap into the interior of the slot 802 on the first clamping plate 801. At the same time, the wire holes 805 on the first clamping plate 801 and the second clamping plate 804 are directly sleeved on the outside of the wire at the rear side of the connector, so that the connector will not move out of the interior of the interface 12. In summary, when inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are directly separated through the groove 806, and then it is not necessary to pull the two clamping plates when inserting the connector into the interior of the interface 12 later, making it more convenient to insert the connector into the interior of the interface 12.

[0047] Through the above technical solutions: 1. By pulling the fixed plate 503 and causing the front side of the fixed plate 503 to move out of the interior of the fixed slot 502, then pulling the T-shaped plate 501 upward and causing the T-shaped plate 501 not to press on the folded filter cartridge 402, and then grasping the folded filter cartridge 402 and lifting it upward, so that the folded filter cartridge 402 and the bottom plate 401 directly move out of the interior of the mounting frame 2 through the placement groove 3. Then pour out the silica gel desiccant inside the folded filter cartridge 402 and pour new silica gel desiccant into the interior of the folded filter cartridge 402. In summary, when replacing the silica gel desiccant inside the folded filter cartridge 402, directly pull the fixed plate 503 outward, and then move the T-shaped plate 501 out of the top of the folded filter cartridge 402 to move the folded filter cartridge 402 out of the interior of the mounting frame 2, making it more convenient to replace the silica gel desiccant inside the folded filter cartridge 402; 2. When inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are pulled through the groove 806, causing them to separate. After inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are directly moved, causing the latch 803 on the second clamping plate 804 to snap into the interior of the slot 802 on the first clamping plate 801. At the same time, the wire holes 805 on the first clamping plate 801 and the second clamping plate 804 are directly sleeved on the outside of the wire at the rear side of the connector, so that the connector will not move out of the interior of the interface 12. In summary, when inserting the connector into the interior of the interface 12, the first clamping plate 801 and the second clamping plate 804 are directly separated through the groove 806, and then it is not necessary to pull the two clamping plates when inserting the connector into the interior of the interface 12 later, making it more convenient to insert the connector into the interior of the interface 12.
