[0017] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail 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, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] For example, see Figure 1 - Fig.14The present invention provides a technical solution for an optical cable junction box with a safety protection function: the optical cable junction box with a safety protection function comprises: an optical cable junction box body 1, an inner wall of one side of the optical cable junction box body 1 is movably connected with an optical cable protection door 11, one side of the inner part of the optical cable protection door 11 is fixedly connected with a device shell 2, one side of the inner part of the optical cable junction box body 1 is provided with an insertion rod 22 at the position of the device shell 2, a safety component is arranged inside the device shell 2, an unlocking groove 33 is provided inside the device shell 2, a positioning rod 32 is fixedly connected to the inner wall at one end of the unlocking groove 33, an unlocking rod 3 is movably inserted inside the unlocking groove 33, a positioning hole 34 is provided on the outer wall at one end of the unlocking groove 33, the inner part of the positioning hole 34 is movably inserted with the outer wall of the positioning rod 32, an active rod 74 is slidably connected to the inner part, and one end of the active rod 74 is The outer wall is fixedly connected to a push spring 275, and a first square hole 76 is provided on the outer wall on one side of the unlocking rod 3. The outer wall at the bottom of the first square hole 76 is connected through the outer wall at the top of the positioning hole 34. The outer wall of the active rod 74 is movably plugged into the inside of the first square hole 76. A limiting groove is provided on the outside of one side of the active rod 74, and a reset rod 31 is slidably connected to the inside of the limiting groove. A placement groove 81 is provided on the inner wall of the unlocking rod 3 close to the first square hole 76, and an elastic block 82 is fixedly connected to the inner wall of the placement groove 81. The elastic block 82 and the outer wall of one end of the elastic block 82 are fixedly connected to a magnetic plate 28, and the outer wall of the magnetic plate 28 is slidably connected to the inside of the first square hole 76. The lower part of the outer wall of one side of the magnetic plate 28 is in movably 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 on one side of the placement groove 81.

[0019] The active rod 74 is blocked inside the unlocking rod 3 to prevent the active rod 74 from extending from the first square hole 76. When the unlocking rod 3 is inserted into the unlocking groove 33, friction will be generated between the active rod 74 and the inner wall of the unlocking groove 33, thereby increasing the resistance of the unlocking rod 3 to be inserted into the unlocking groove 33. At the same time, under long-term use, the friction force will also cause damage to the contact surface of the two, thereby correspondingly increasing the efficiency of the unlocking rod 3 being inserted into the unlocking groove 33, thereby protecting the active rod 74.

[0020] Embodiment 2, on the basis of embodiment 1, the outer wall of the interior of the device shell 2 located on one side of the movable groove 24 is provided with a slide groove 5, a T-shaped groove 51 is provided below the bottom of the slide groove 5, a baffle 52 is slidably connected to the interior of the slide groove 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 interior of the baffle 52, the outer wall of one side of the slide groove 5 is in active contact with the outer wall of the other end of the jack 21, the interior of the device shell 2 is provided with a cavity 72 located on one side of the slide groove 5, a push plate 7 is slidably connected to the interior of the cavity 72, a reset spring 71 is fixedly connected to the outer wall of one side of the push plate 7, and the two reset springs 71 are fixedly connected to the outer wall of one side of the push plate 7. The outer wall of one end of the spring 71 is fixedly connected to the inner wall of the cavity 72, the outer wall of one side of the push plate 7 is fixedly connected to a sliding shell 73, the interior of the sliding shell 73 is slidably connected to the fixed frame 6, the outer wall of the top of the push plate 7 is in active contact with the outer wall of the bottom of the fixed frame 6, the outer walls on both sides of the fixed frame 6 are fixedly connected to sliders 62, the interior of the cavity 72 is provided with a second slide groove 61, the interior of the second slide groove 61 is slidably connected to the outer wall of the slider 62, the outer wall of one side of the fixed frame 6 is provided with a guide groove 55, the outer wall of one side of the baffle 52 is provided with a groove, the interior of the groove is fixedly connected to a guide rod 54, and the outer wall of the guide rod 54 is slidably connected to the interior of the guide groove 55.

[0021] The push plate 7 is inside the cavity 72 and does not directly contact the unlocking groove 33, so that even if a person who forcibly unlocks the lock inserts a foreign object into the unlocking groove 33, the push plate 7 cannot be pushed, thereby increasing the safety of the push plate 7 and protecting the optical fiber equipment inside the optical cable junction box body 1, thereby preventing a person who forcibly unlocks the lock from opening the optical cable protection door 11 to damage the optical fiber facilities inside the optical cable junction box body 1; The baffle 52 can be driven to release the limit on the jack 21 only by the upward movement of the fixing frame 6. This mechanism increases the safety of the optical cable junction box body 1 and prevents the person from forcibly unlocking the lock by trying to operate by inserting a rod into the cavity 72. If the rod is not long enough, the fixing frame 6 cannot drive the baffle 52 to move, thereby failing to release the limit on the jack 21 and opening the optical cable protection door 11. In this way, the optical fiber equipment inside the optical cable junction box body 1 is effectively protected.

[0022] Embodiment 3, on the basis of embodiment 2, includes a socket 21, the outer wall of the socket 21 is slidably connected to the inside of the device shell 2, the outer wall of one end of the socket 21 is movably plugged into the inside of the plug rod 22, a movable groove 24 is provided inside the device shell 2, the outer wall of the socket 21 is slidably connected to the inside of the movable groove 24, the shape of the socket 21 is L-shaped, the outer wall of the other end of the socket 21 is fixedly connected to a push spring 23, the outer wall of one end of the push spring 23 is fixedly connected to the inner wall of one side of the movable groove 24, and the inside of one side of the socket 21 is fixedly connected to a magnetic plate 83.

[0023] Only a through hole of the cavity 72 can be seen from the inside of the unlocking slot 33, which confuses those who forcibly open the lock 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 to the socket 21, the socket 21 cannot be easily opened from the inside of the plug rod 22 due to the action of the push spring 1 23. The design of the push spring 1 23 increases the fixing force of the socket 21 on the plug rod 22. Even if someone tries to interfere with the socket 21 through external means, the socket 21 can still be firmly maintained inside the plug rod 22 due to the elastic force of the spring. In this way, the optical cable protection door 11 of the optical cable junction box body 1 is effectively protected to prevent human intrusion and damage.

[0024] Embodiment 4, on the basis of embodiment 3, an anti-blocking plate 4 is movably inserted into the inner wall of one end of the unlocking groove 33, an iron plate 43 is fixedly connected to the inside of the anti-blocking plate 4, a rubber pad 41 is fixedly connected to the outer wall of the anti-blocking plate 4, and an installation groove is provided on the outer wall of one side of the equipment shell 2 below the unlocking groove 33, a rotating rod 42 is fixedly connected to the inside of the installation groove, and the outer wall of the rotating rod 42 is rotatably connected to the inside of the anti-blocking plate 4.

[0025] By driving the rubber pad 41 through the anti-blocking plate 4 to be inserted into the unlocking groove 33, the unlocking groove 33 can be sealed, preventing debris from entering the unlocking groove 33, and correspondingly increasing the cleanliness of the unlocking groove 33, preventing the internal structure of the device shell 2 from being stuck due to the entry of debris, and further increasing the smoothness of the internal structure of the device shell 2 during operation. At the same time, the provision 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 the two, further improving the stability of the anti-blocking plate 4 fixation, and by hiding the iron plate 43 inside the anti-blocking plate 4, it is correspondingly prevented from manually using tools such as magnets to try to open the anti-blocking plate 4, thereby increasing the safety of the optical cable junction box body 1.

[0026] In actual use, when it is necessary to open the optical cable protection door 11 on the optical cable junction box body 1, the professional will first use the unlocking rod 3 that matches the unlocking slot 33 on the equipment shell 2. In this process, the magnetic plate 28 on the unlocking rod 3 will be attached to the anti-blocking plate 4, and the magnetic attraction between the magnetic plate 28 and the iron plate 1 43 hidden inside the anti-blocking plate 4 will be used to move the anti-blocking plate 4 out of the unlocking slot 33, so that the magnetic plate 28 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 be rotated 180 degrees around the rotating rod 42 to rotate to the bottom of the rotating rod 42, so that it will not hinder the unlocking rod 3 from being inserted into the unlocking slot 33, and the anti-blocking plate 4 drives the anti-blocking plate 4 to move out of the unlocking slot 33. The rubber pad 41 is inserted into the unlocking groove 33 to seal the unlocking groove 33, thereby preventing debris from entering the unlocking groove 33, and correspondingly increasing the cleanliness of the unlocking groove 33, preventing the internal structure of the device shell 2 from getting stuck due to the entry of debris, and further increasing the smoothness of the internal structure of the device shell 2 during operation. At the same time, the provision 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 the two, further improving the stability of the anti-blocking plate 4 fixation, and by hiding the iron plate 43 inside the anti-blocking plate 4, it is correspondingly prevented from manually using tools such as magnets to try to open the anti-blocking plate 4, thereby increasing the safety of the optical cable junction box body 1.

[0027] After the anti-blocking plate 4 is removed from the unlocking slot 33, the unlocking rod 3 can be aligned with the unlocking slot 33 and inserted by a professional. During the process of inserting the unlocking rod 3 into the unlocking slot 33, the positioning rod 32 can be inserted into the inside of the positioning hole 34. At this time, when the unlocking rod 3 continues to move into the inside of the unlocking slot 33, the positioning rod 32 can push the magnetic plate 8 to make the magnetic plate 8 enter the position of the second square hole 84 from the first square hole 76. Before the unlocking rod 3 enters the inside of the unlocking slot 33, the magnetic plate 8 When the unlocking rod 3 is inserted into the unlocking groove 33, friction will be generated between the active rod 74 and the inner wall of the unlocking groove 33, thereby increasing the resistance of the unlocking rod 3 to be inserted into the unlocking groove 33. At the same time, under long-term use, the friction force will also cause damage to the contact surface of the two, thereby correspondingly increasing the efficiency of the unlocking rod 3 to be inserted into the unlocking groove 33, thereby protecting the active rod 74.

[0028] After the positioning rod 32 pushes the magnetic plate 28 to the position of the second square hole 84, the fixation of the magnetic plate 28 to the active rod 74 can be released. At this time, the outer wall of one end of the unlocking rod 3 is convenient for contacting the inner wall of one side of the unlocking groove 33, so that the first square hole 76 is aligned with the cavity 72 and the second square hole 84 is aligned with the movable groove 24. Then, through the action of the pushing spring 2 75, the active rod 74 can be pushed out of the first square hole 76, so that the first square hole 76 pushes the push plate 7, and then the push plate 7 is forced to move into the inside of the cavity 72. By sliding the push plate 7 at the bottom of the fixing frame 6 toward the inside of the cavity 72, the fixing frame 6 can be moved upward by the movement of the push plate 7. By pushing, the fixing frame 6 can drive the slider 62 to move upward inside the second slide groove 61. By sliding the slider 62 inside the second slide groove 61, the movement trajectory of the fixing frame 6 can be limited to ensure the stability of the movement of the fixing frame 6. The push plate 7 is inside the cavity 72 and does not directly contact the unlocking groove 33, which prevents the person who forcibly unlocks the lock from inserting foreign objects into the unlocking groove 33. The safety of the push plate 7 is increased accordingly, and the optical fiber equipment inside the optical cable junction box body 1 is protected at the same time, which prevents the optical fiber facilities inside the optical cable junction box body 1 from being damaged by artificially opening the optical cable protection door 11.

[0029] It should be noted that the elastic force of the second push spring 75 itself is greater than the elastic force of the return spring 71 itself.

[0030] When the fixing frame 6 moves in the upward direction, the guide slot 55 can be driven to move upward, and then the guide slot 55 can be driven to move upward, and the guide rod 54 can be driven to move accordingly. Since the T-shaped block 53 and the T-shaped slot 51 are both 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 guide slot 55 on the fixing frame 6, when the fixing frame 6 drives the guide slot 55 to move upward, the guide rod 54 can drive the baffle 52 to slide inside the guide slot 55, so that the baffle 52 drives the T-shaped The block 53 moves inside the T-slot 51, thereby releasing the limit of the baffle 52 on the jack 21. The baffle 52 can be driven to release the limit of the jack 21 only by the upward movement of the fixing frame 6. This mechanism increases the safety of the optical cable junction box body 1 and prevents the person from forcibly unlocking the lock. Even if the person tries to operate by inserting a rod into the cavity 72, the rod is not long enough to make the fixing frame 6 drive the baffle 52 to move, thereby failing to release the limit of the jack 21 and failing to open the optical cable protection door 11. In this way, the optical fiber equipment inside the optical cable junction box body 1 is effectively protected.

[0031] It should be noted that: by sliding the sliding shell 73 on the fixing frame 6, when the return spring 71 pushes the push plate 7 to return to its original position, the setting of the sliding shell 73 can drive the fixing frame 6 to return to its original position.

[0032] After the fixing of the baffle 52 to the insertion hole 21 is released, the magnetic plate 28 can attract the magnetic plate 1 83 to move into the movable groove 24 under the effect of the attraction between the opposite poles of the magnetic plate 28 and the magnetic plate 1 83. Then, through the movement of the magnetic plate 1 83, the magnetic plate 1 83 can drive the insertion hole 21 to move out from the inside of the insertion rod 22, so as to open the movable door. Only a through hole of the cavity 72 can be seen from the inside of the unlocking groove 33, which confuses the forcible unlocker and makes them focus on studying how to push the push plate 7. However, even if they successfully push the push plate 7, The push plate 7 is moved to release the fixation of the baffle 52 to the socket 21. Due to the action of the push spring 23, the socket 21 cannot be easily opened from the inside of the plug rod 22. The design of the push spring 23 increases the fixing force of the socket 21 to the plug rod 22. Even if someone tries to interfere with the socket 21 through external means, the socket 21 can still be firmly maintained inside the plug rod 22 due to the elastic force of the spring. In this way, the optical cable protection door 11 of the optical cable junction box body 1 is effectively protected to prevent illegal intrusion and damage.

[0033] It should be noted that the attraction force between the opposite poles of the magnetic plate 1 83 and the magnetic plate 2 8 is greater than the elastic force of the push spring 1 23 itself.

[0034] It should be noted that: an iron plate 2 is arranged inside the partition where the movable groove 24 is aligned with the second square hole 84, and an iron plate 2 is placed between the magnetic plate 1 83 and the magnetic plate 2 8. The iron plate 2 can serve as a "bridge" for the magnetic lines of force, so that the magnetic lines of force form a tighter closed loop between the two magnetic blocks, thereby enhancing the suction between the magnetic blocks.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
