Description

Technical Field

[0001] The present invention relates to the field of optical cable distribution boxes, and specifically to an optical cable distribution box with a safety protection function. Background Art

[0002] An optical cable distribution box is a connection device that provides optical cable termination and cross-connection for backbone optical cables and distribution optical cables.

[0033] In order to clearly and completely describe the purpose and technical solutions of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Embodiment 1, please refer to Figure 1 - Figure 14, the present invention provides a technical solution for an optical cable distribution box with a safety protection function: The optical cable distribution box with a safety protection function includes: an optical cable distribution box body 1, one side inner wall of the optical cable distribution box body 1 is movably connected with an optical cable protection door 11, one side inside the optical cable protection door 11 is fixedly connected with an equipment shell 2, a plug rod 22 is provided at the position of the equipment shell 2 on one side inside the optical cable distribution box body 1, a safety component is arranged inside the equipment shell 2, an unlocking groove 33 is provided on the inner wall of one end of the unlocking groove 33, a positioning rod 32 is fixedly connected to the inner wall of one end of the unlocking groove 33, an unlocking rod 3 is movably inserted into the unlocking groove 33, a positioning hole 34 is provided on the outer wall of one end of the unlocking groove 33, the inside of the positioning hole 34 is movably inserted with the outer wall of the positioning rod 32, a driving rod 74 is slidably connected inside, a second pushing spring 75 is fixedly connected to the outer wall of one end of the driving rod 74, a first square hole 76 is provided on the outer wall of one side of the unlocking rod 3, the outer wall of the bottom of the first square hole 76 is connected through the outer wall of the top of the positioning hole 34, the outer wall of the driving rod 74 is movably inserted into the inside of the first square hole 76, a limiting groove is provided on the outer side of one side of the driving rod 74, a reset rod 31 is slidably connected inside the limiting groove, a placing groove 81 is provided on the inner wall of the unlocking rod 3 close to the first square hole 76, an elastic block 82 is fixedly connected to the inner wall of the placing groove 81, the elastic block 82, an outer wall of one end of the elastic block 82 is fixedly connected with a second magnetic plate 8, the outer wall of the second magnetic plate 8 is slidably connected to the inside of the first square hole 76, the lower part of the outer wall of one side of the second magnetic plate 8 is in movable contact with the outer wall of one end of the positioning rod 32, and a second square hole 84 is provided on the inner wall of one side of the placing groove 81.

[0035] By blocking the driving rod 74 inside the unlocking rod 3, it is avoided that the driving rod 74 extends out from the first square hole 76. When the unlocking rod 3 is inserted into the unlocking groove 33, the driving rod 74 will rub against the inner wall of the unlocking groove 33, increasing the resistance of the unlocking rod 3 inserted into the unlocking groove 33. At the same time, under long-term use, the friction force will also damage the contact surfaces of the two, correspondingly increasing the efficiency of the unlocking rod 3 inserted into the unlocking groove 33, and protecting the driving rod 74.

[0036] Embodiment 2, on the basis of Embodiment 1, a first chute 5 is opened on the outer wall of the interior of the equipment housing 2 on one side of the moving groove 24. A T-shaped groove 51 is opened below the bottom of the first chute 5. A baffle 52 is slidably connected inside the first chute 5. A T-shaped block 53 is fixedly connected to the outer wall of the bottom of the baffle 52. The outer wall of the T-shaped block 53 is slidably connected to the inside of the baffle 52. The outer wall of one side of the first chute 5 is in movable contact with the outer wall of the other end of the jack 21. A cavity 72 is opened on one side of the interior of the equipment housing 2 where the first chute 5 is located. A push plate 7 is slidably connected inside the cavity 72. A return spring 71 is fixedly connected to the outer wall of one side of the push plate 7. One end of the two return springs 71 is fixedly connected to the inner wall of the cavity 72. A sliding housing 73 is fixedly connected to the outer wall of one side of the push plate 7. A fixing frame 6 is slidably connected inside the sliding housing 73. The outer wall of the top of the push plate 7 is in movable contact with the outer wall of the bottom of the fixing frame 6. Sliders 62 are fixedly connected to the outer walls of both sides of the fixing frame 6. A second chute 61 is opened inside the cavity 72. The inside of the second chute 61 is slidably connected to the outer wall of the slider 62. A guiding groove 55 is opened on the outer wall of one side of the fixing frame 6. A groove is opened on the outer wall of one side of the baffle 52. A guiding rod 54 is fixedly connected inside the groove. The outer wall of the guiding rod 54 is slidably connected to the inside of the guiding groove 55.

[0037] Since the push plate 7 is inside the cavity 72 and does not directly contact the unlocking groove 33, it prevents the forced unlocker from being able to push the push plate 7 even if a foreign object is inserted into the unlocking groove 33. Correspondingly, the safety of the push plate 7 is increased, and at the same time, the optical fiber equipment inside the optical cable distribution box body 1 is protected, preventing the forced unlocker from opening the optical cable protection door 11 to damage the optical fiber facilities inside the optical cable distribution box body 1.

[0038] Only when the fixing frame 6 moves upward can the baffle 52 be driven to release the limit on the jack 21. This mechanism increases the safety of the optical cable distribution box body 1. It prevents the forced unlocker from being able to operate by inserting a rod into the cavity 72 even if they try. Since the length of the rod is not enough, the fixing frame 6 cannot drive the baffle 52 to move, so the limit on the jack 21 cannot be released, and the optical cable protection door 11 cannot be opened. In this way, the optical fiber equipment inside the optical cable distribution box body 1 is effectively protected.

[0039] Embodiment 3, on the basis of Embodiment 2, includes a jack 21. The outer wall of the jack 21 is slidably connected to the inside of the equipment housing 2. The outer wall of one end of the jack 21 is movably inserted into the inside of the insertion rod 22. A moving groove 24 is opened inside the equipment housing 2. The outer wall of the jack 21 is slidably connected to the inside of the moving groove 24. The shape of the jack 21 is L-shaped. A first pushing spring 23 is fixedly connected to the outer wall of the other end of the jack 21. One end of the first pushing spring 23 is fixedly connected to the inner wall of one side of the moving groove 24. A first magnetic plate 83 is fixedly connected to the inside of one side of the jack 21.

[0040] Only a through hole of a cavity 72 can be seen from inside the unlocking groove 33, thus confusing those who attempt to unlock the lock by force and making them focus on researching how to push the push plate 7. However, even if they succeed in pushing the push plate 7 to release the fixing of the jack 21 by the baffle 52, due to the action of the first pushing spring 23, the jack 21 cannot be easily opened from inside the plug rod 22. The design of the first pushing spring 23 increases the fixing force of the jack 21 on the plug rod 22. Even if someone tries to interfere with the jack 21 by external means, due to the elastic force of the spring, the jack 21 can still firmly remain inside the plug rod 22. In this way, the optical cable protection door 11 of the optical cable cross-connect box body 1 is effectively protected against human intrusion and damage.

[0041] Embodiment 4: On the basis of Embodiment 3, a anti-blocking plate 4 is movably inserted into the inner wall at one end of the unlocking groove 33. A first iron plate 43 is fixedly connected inside the anti-blocking plate 4. A rubber pad 41 is fixedly connected to the outer wall of the anti-blocking plate 4. An installation groove is formed in the outer wall of one side of the equipment shell 2 below the unlocking groove 33. A rotating rod 42 is fixedly connected inside the installation groove. The outer wall of the rotating rod 42 is rotatably connected to the inside of the anti-blocking plate 4.

[0042] By driving the rubber pad 41 to insert into the unlocking groove 33 through the anti-blocking plate 4, the unlocking groove 33 can be sealed, preventing sundries from entering the unlocking groove 33. Correspondingly, the cleanliness inside the unlocking groove 33 is increased, preventing the internal structure of the equipment shell 2 from jamming due to the entry of sundries, and further increasing the smoothness of the internal structure of the equipment shell 2 during operation. At the same time, the setting of the rubber pad 41 not only fills the gap between the anti-blocking plate 4 and the unlocking groove 33, but also increases the friction between them, further improving the fixing stability of the anti-blocking plate 4. By hiding the first iron plate 43 inside the anti-blocking plate 4, it correspondingly prevents people from using tools such as magnets to try to pull open the anti-blocking plate 4, increasing the security of the optical cable cross-connect box body 1.

[0043] In actual use, when it is necessary to open the optical cable protection door 11 on the optical cable cross-connect box body 1, professional personnel will first use the unlocking rod 3 that matches the unlocking slot 33 on the equipment shell 2. During this process, the second magnetic plate 8 on the unlocking rod 3 will be attached to the anti-blocking plate 4. By using the magnetic attraction force between the second magnetic plate 8 and the first iron plate 43 hidden inside the anti-blocking plate 4, the anti-blocking plate 4 is moved out of the unlocking slot 33, and the second magnetic plate 8 drives the anti-blocking plate 4 to move out of the unlocking slot 33. After the anti-blocking plate 4 is moved out of the unlocking slot 33, it can rotate 180 degrees around the rotating rod 42 and turn to the bottom of the rotating rod 42, so that it will not prevent the unlocking rod 3 from being inserted into the unlocking slot 33. By driving the rubber pad 41 to insert into the unlocking slot 33 through the anti-blocking plate 4, the unlocking slot 33 can be sealed, preventing sundries from entering the unlocking slot 33, correspondingly increasing the cleanliness inside the unlocking slot 33, preventing the internal structure of the equipment shell 2 from being stuck due to the entry of sundries, and further increasing the smoothness of the internal structure of the equipment shell 2 during operation. At the same time, the setting of the rubber pad 41 not only fills the gap between the anti-blocking plate 4 and the unlocking slot 33, but also increases the friction between the two, further improving the fixing stability of the anti-blocking plate 4. By hiding the first iron plate 43 inside the anti-blocking plate 4, it correspondingly prevents people from using tools such as magnets to try to pull open the anti-blocking plate 4, increasing the safety of the optical cable cross-connect box body 1.

[0044] After removing the anti-blocking plate 4 from the unlocking slot 33, professional personnel can align and insert the unlocking rod 3 into the unlocking slot 33. During the process of inserting the unlocking rod 3 into the unlocking slot 33, the positioning rod 32 can be inserted into the positioning hole 34. At this time, when the unlocking rod 3 continues to move into the unlocking slot 33, the positioning rod 32 can push the second magnetic plate 8, so that the second magnetic plate 8 enters the position of the second square hole 84 from the first square hole 76. Before the unlocking rod 3 enters the unlocking slot 33, the second magnetic plate 8 is at the position of the first square hole 76, which can block the active rod 74 inside the unlocking rod 3, preventing the active rod 74 from protruding from the first square hole 76. When the unlocking rod 3 is inserted into the unlocking slot 33, it will cause friction between the active rod 74 and the inner wall of the unlocking slot 33, increasing the resistance of the unlocking rod 3 to be inserted into the unlocking slot 33. At the same time, under long-term use, the friction will also damage the contact surfaces of the two, correspondingly increasing the efficiency of the unlocking rod 3 inserted into the unlocking slot 33 by protecting the active rod 74.

[0045] After the positioning rod 32 pushes the second magnetic plate 8 to the position of the second square hole 84, the fixation of the second magnetic plate 8 on the active rod 74 can be released. At this time, the outer wall of one end of the unlocking rod 3 comes into contact with the inner wall of one side of the unlocking groove 33, aligning the first square hole 76 with the cavity 72 and the second square hole 84 with the moving groove 24 simultaneously. Then, under the action of the pushing spring two 75, the active rod 74 can be pushed out from the first square hole 76, so that the first square hole 76 pushes the push plate 7, and then the push plate 7 moves inward into the cavity 72 under force. By sliding the push plate 7 at the bottom of the fixing frame 6 into the cavity 72, the push plate 7 can push the fixing frame 6 upward, enabling the fixing frame 6 to drive the slider 62 to move upward inside the second chute 61. By sliding the slider 62 inside the second chute 61, the movement track of the fixing frame 6 can be limited to ensure the stability of the movement of the fixing frame 6. Since the push plate 7 is inside the cavity 72 and does not directly contact the unlocking groove 33, even if a foreign object is inserted into the unlocking groove 33 by a forced unlocker, the push plate 7 cannot be pushed, correspondingly increasing the safety of the push plate 7 and protecting the optical fiber equipment inside the optical cable distribution box body 1 at the same time, preventing the optical cable protection door 11 from being opened artificially to damage the optical fiber facilities inside the optical cable distribution box body 1.

[0046] It should be noted that: the elastic force of the pushing spring two 75 itself is greater than the elastic force of the reset spring 71 itself.

[0047] When the fixing frame 6 moves, it can drive the guiding groove 55 to move upward accordingly. Then, through the upward movement of the guiding groove 55, the guiding rod 54 can be driven to move accordingly. Since both the T-shaped block 53 and the T-shaped groove 51 are T-shaped, the T-shaped block 53 can limit the baffle 52 to prevent the baffle 52 from moving upward with the fixing frame 6. At this time, through the inclination angle of the guiding groove 55 on the fixing frame 6, when the fixing frame 6 drives the guiding groove 55 to move upward, the guiding rod 54 can drive the baffle 52 to slide inside the guiding groove 55, so that the baffle 52 drives the T-shaped block 53 to move inside the T-shaped groove 51, thus releasing the limitation of the baffle 52 on the jack 21. Only when the fixing frame 6 moves upward can the baffle 52 be driven to release the limitation on the jack 21. This mechanism increases the safety of the optical cable distribution box body 1. Preventing a forced unlocker from attempting to operate by inserting a rod into the cavity 72, if the length of the rod is not enough, the fixing frame 6 cannot drive the baffle 52 to move, so the limitation on the jack 21 cannot be released, and the optical cable protection door 11 cannot be opened. In this way, the optical fiber equipment inside the optical cable distribution box body 1 is effectively protected.

[0048] It should be noted that: by sliding the sliding shell 73 on the fixing frame 6, when the reset spring 71 pushes the push plate 7 to return to its original position, through the setting of the sliding shell 73, the fixing frame 6 can be driven to return to its original position accordingly.

[0049] After releasing the fixation of the baffle 52 on the jack 21, under the action of the attraction between the opposite poles of the second magnetic plate 8 and the first magnetic plate 83, the second magnetic plate 8 can attract the first magnetic plate 83 to move inside the moving groove 24. Then, through the movement of the first magnetic plate 83, the first magnetic plate 83 can drive the jack 21 to move out of the inside of the plug rod 22, thereby opening the movable door. From the unlocking groove 33, only a through hole of a cavity 72 can be seen, which confuses the forced unlockers and makes them focus on studying how to push the push plate 7. However, even if they successfully push the push plate 7 to release the fixation of the baffle 52 on the jack 21, due to the action of the first pushing spring 23, the jack 21 cannot be easily opened from the inside of the plug rod 22. The design of the first pushing spring 23 increases the fixing force of the jack 21 on the plug rod 22. Even if someone tries to interfere with the jack 21 by external means, due to the elastic force of the spring, the jack 21 can still be firmly held inside the plug rod 22. In this way, the optical cable protection door 11 of the optical cable distribution box body 1 is effectively protected against illegal intrusion and damage.

[0050] It should be noted that: the attraction force between the opposite poles of the first magnetic plate 83 and the second magnetic plate 8 is greater than the elastic force of the first pushing spring 23 itself.

[0051] It should be noted that: an iron plate two is arranged inside the partition where the moving groove 24 is aligned with the second square hole 84. An iron plate two is placed between the first magnetic plate 83 and the second magnetic plate 8. The iron plate two can serve as a "bridge" for magnetic force lines, enabling the magnetic force lines to form a closer closed loop between the two magnetic blocks, thereby enhancing the suction force between the magnetic blocks.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
