Description

Technical Field

[0001] The invention belongs to the technical field of shock absorbing components, and in particular relates to an optical fiber distribution frame with a bottom shock absorbing component. Background Art

[0002] Fiber optic distribution frames are used for the termination and distribution of trunk optical cables at the local end of fiber optic communication systems. They can easily realize the connection, distribution and scheduling of optical fiber lines. As the degree of network integration becomes higher and higher, the bottom shock-absorbing components effectively reduce the impact of vibration on the fiber optic distribution frame and improve the stability of the system.

[0003] Shock absorbers are important mechanical devices that protect equipment and structures from damage by absorbing, reducing or eliminating vibration and impact energy. Different types of shock absorbers have different characteristics and application scenarios. Choosing appropriate shock absorbers is crucial to ensuring the stability and reliability of equipment and structures.

[0004] However, the conventional device still has the following problems when used:

[0005] The patent application publication number is CN 212255797U, which discloses a fiber optic distribution frame. Although the cover of this device can be opened to facilitate the cleaning of dust inside, the rotation of the fan can not only remove dust, but also dry the residual cleaning liquid to prevent internal mold from affecting the use of the device. However, when the fiber optic distribution frame is used, it has no shock-absorbing effect. The vibration force makes the fiber optic distribution frame and its internal optical fiber lines unstable, thereby affecting the stable transmission of optical signals.

[0035] When the tooth seat 9 is fixed by the limiting teeth 103, the tooth seat 9 can remain stationary when it is not needed to work, avoiding the displacement of the tooth seat 9 when not working, making the fixing of the limiting rod 13 by the toothed plate 41 not firm enough, and correspondingly increasing the stability of the toothed plate 41, preventing the toothed plate 41 from moving when it is not needed.

[0036] Embodiment 3, on the basis of embodiment 2, a cavity 51 is provided inside the mounting plate 5, a slide groove 52 is provided at the top of the cavity 51 at the position of the moving block 42, an outer wall on one side of the cavity 51 is connected through the outer wall on one side of the track 21, the upper part of the outer wall of the moving block 42 is slidably connected to the inside of the slide groove 52, the inside of the cavity 51 is slidably connected to the outer wall of the connecting rod 43, the lower part of the outer wall of the moving block 42 is slidably connected to the inside of the cavity 51, and the outer wall at the top of the mounting plate 5 is fixedly connected between the elastic plate 1 3 and the elastic plate 2 4.

The top of the driving rod 44 is fixedly connected to a gear seat 9, and the outer wall at the top of the gear seat 9 is meshingly connected to a gear 92. The axis of the gear 92 passes through and is fixedly connected to a rotating rod 91. The outer wall of one end of the rotating rod 91 is rotatably connected to the inside of the square groove, and the outer wall of the rotating rod 91 is fixedly connected to a handle 93.

[0037] By increasing the gap between the elastic plate 2 4 and the elastic plate 1 3 , it is convenient for the bottom plate 11 to drive the limiting rod 13 to be inserted between the elastic plate 2 4 and the elastic plate 1 3 , thereby avoiding the situation where the gap between the elastic plate 1 3 and the elastic plate 2 4 is too small to facilitate the limiting rod 13 to be inserted, and correspondingly increasing the efficiency of the limiting rod 13 being inserted between the elastic plate 1 3 and the elastic plate 2 4 , further increasing the fixation of the limiting rod 13 , and then driving the elastic plate 2 4 to move through the tooth seat 9 so as to fix the limiting rods 13 of different sizes, thereby increasing the flexibility between the elastic plate 2 4 and the elastic plate 1 3 , thereby increasing the application range of the shock absorbing box 2 .

[0038] Embodiment 4, on the basis of embodiment 3, the outer wall at the top of the mounting plate 5 is fixedly connected to the fixed shell 6, the interior of the fixed shell 6 is fixedly connected to the elastic block 62, the outer wall at the top of the elastic block 62 is fixedly connected to the movable plate 61, the outer wall of the movable plate 61 is slidably connected to the interior of the fixed shell 6, the outer wall on one side of the movable plate 61 is fixedly connected to the L-shaped plate 7, the interior of the L-shaped plate 7 is provided with a movable groove, the interior of the movable groove is fixedly connected to a push spring 73, the outer wall at one end of the push spring 73 is fixedly connected to a slider 74, the outer wall at one end of the slider 74 is slidably connected to the interior of the movable groove, the outer wall on one side of the slider 74 is fixedly connected to the push rod 71, the push spring 73 is fixedly connected to the outer wall at one end of the push spring 73, the outer wall at one end of the slider 74 is slidably connected to the interior of the movable groove, the outer wall on one side of the slider 74 is fixedly connected to the push rod 71, The outer wall on one side of the rod 71 is fixedly connected to a fixed plate 72, and the outer wall on one side of the fixed plate 72 is in movably contact with the outer wall on one side of the elastic plate 2 4, the outer wall of the push rod 71 is slidably connected to the inside of the L-shaped plate 7, the outer wall on the opposite side of the elastic plate 2 4 and the elastic plate 1 3 is fixedly connected to a toothed plate 41, the internal sliding insertion of the two toothed plates 41 is connected to a limiting rod 13, the protrusions on the toothed plate 41 are movably inserted into the triangular groove on the limiting rod 13, the outer walls at both ends of the bottom of the elastic plate 2 4 are fixedly connected to moving blocks 42, the outer walls on the opposite side of the two moving blocks 42 are fixedly connected to a connecting rod 43, and the outer wall on one side of the moving block 42 is fixedly connected to a driving rod 44.

[0039] By fixing the fixing plate 72 to one side of the elastic plate 24, the fixing force on the elastic plate 24 can be increased, and the elastic plate 24 is prevented from being deformed when being subjected to force, so that the toothed plate 41 is prevented from being separated from the inside of the limiting rod 13, and the fixing of the elastic plate 24 is further increased, so that the toothed plate 41 is more firmly fixed to the other side of the limiting rod 13. By fixing the limiting rod 13, the fixation of the optical fiber distribution frame body 1 can be increased, and the displacement of the optical fiber distribution frame body 1 during operation is avoided, and the stability of the optical fiber distribution frame body 1 is correspondingly increased, so that the optical signal is transmitted stably.

[0040] Embodiment 5, on the basis of embodiment 1, mounting grooves are provided below the outer walls on the opposite sides of the elastic plates 2 4 and 1 3, a fixing rod 81 is slidably connected inside the mounting groove, a rubber strip 8 is fixedly connected to the outer wall on one side of the fixing rod 81, and the outer walls of the rubber strip 8 are in active contact with the outer walls of the elastic plates 2 4 and 1 3 respectively.

[0041] By providing the rubber strip 8 at the bottom of the elastic plate 1 3 and the elastic plate 2 4, when the elastic plate 1 3 and the elastic plate 2 4 are subjected to external force, the rubber strip 8 can absorb part of the impact force and reduce the energy directly transmitted to the elastic plate 1 3 and the elastic plate 2 4, thereby alleviating the burden on the elastic plate 1 3 and the elastic plate 2 4 and further increasing the service life of the elastic plate 1 3 and the elastic plate 2 4. Furthermore, by adding the rubber strip 8, the vibration amplitude can be further reduced and the shock absorption performance of the entire structure can be improved.

[0042] The working principle and use process of the present invention are as follows: during operation, first, the operator rotates the threaded rod 101 counterclockwise, and then the threaded rod 101 moves upward, so that the installation rod 102 drives the limiting tooth 103 to move upward, so that the bottom of the limiting tooth 103 leaves the top of the tooth seat 9, and the fixing of the limiting tooth 103 to the tooth seat 9 can be released, and then the sliding rod 104 can move with the installation rod 102, thereby limiting the movement and fixing of the installation rod 102, avoiding the installation rod 102 When the position deviation occurs during movement, the stability of the installation rod 102 during movement is increased accordingly, so that the installation rod 102 can fix the gear seat 9 more accurately. When the gear seat 9 is fixed by the limiting teeth 103, the gear seat 9 can remain stationary when it is not needed to work, thereby avoiding displacement of the gear seat 9 when not working, which makes the toothed plate 41 not fix the limiting rod 13 firmly enough, and correspondingly increases the stability of the toothed plate 41, preventing the toothed plate 41 from moving when it does not need to move.

[0043] After the gear holder 9 is released from fixation, the operator turns the handle 93 clockwise, and the movement of the handle 93 causes the rotating rod 91 to drive the gear 92 to rotate, so that the gear holder 9 moves inside the track 21. Then, the movement of the gear holder 9 drives the two driving rods 44 to move at the same time, and the movement of the driving rod 44 drives the moving block 42 to drive the connecting rod 43 to move inside the cavity 51 and the slide groove 52, so that the two moving blocks 42 drive the elastic plate 2 4 to move to the side away from the elastic plate 1 3, so that the elastic plate 1 3 is moved. The gap between plate 2 4 and elastic plate 1 3 is enlarged, which makes it easier for the bottom plate 11 to drive the limiting rod 13 to be inserted between the elastic plate 2 4 and the elastic plate 1 3, avoiding the gap between the elastic plate 1 3 and the elastic plate 2 4 being too small to facilitate the limiting rod 13 to be inserted, and correspondingly increasing the effect of the limiting rod 13 inserted between the elastic plate 1 3 and the elastic plate 2 4. The limiting rod 13 can be fixed, and then the elastic plate 2 4 can be driven to move by the tooth seat 9, so as to fix the limiting rods 13 of different sizes, thereby increasing the flexibility between the elastic plate 2 4 and the elastic plate 1 3, thereby increasing the application range of the shock absorbing box 2.

[0044] When the bottom plate 11 is brought into the limiting rod 13 and the insertion rod 12 and respectively inserted between the elastic plate 2 4 and the elastic plate 1 3 and into the interior of the groove 32, the handle 93 can be rotated counterclockwise, and then the handle 93 is rotated counterclockwise, so that the tooth seat 9 can drive the driving rod 44 to restore the original position, so that the moving block 42 drives the elastic plate 2 4 to move to the side of the elastic plate 1 3, and then the movement of the elastic plate 2 4 can make the toothed plate 41 move accordingly, so that the protrusion on the toothed plate 41 is inserted into the triangular groove on the limiting rod 13 The limiting rod 13 can be fixed inside, which prevents the limiting rod 13 from falling off from between the elastic plate 2 4 and the elastic plate 1 3 when the frequency of the optical fiber distribution frame body 1 fluctuates greatly. The fixing of the limiting rod 13 is correspondingly increased, and the protrusion on the toothed plate 41 cooperates with the triangular groove on the limiting rod 13, so that the stable connection between the limiting rod 13 and the elastic plate 1 3 and the elastic plate 2 4 is further increased, so that the limiting rod 13 is not easy to slide out after being inserted, thereby increasing the stability between the optical fiber distribution frame body 1 and the shock absorbing box 2.

[0045] After the insertion rod 12 is inserted into the groove 32, the top of the elastic plate 3 can be fixed, so that the elastic plate 3 always drives the toothed plate 41 to be fixed on one side of the limiting rod 13, avoiding the elastic plate 3 from being affected by vibration force during work, so that the elastic plate 3 drives the toothed plate 41 to separate from the limiting rod 13, and correspondingly increases the stability between the elastic plate 3 and the limiting rod 13.

[0046] When the toothed plate 41 is fixed to the other side of the limit rod 13 by the elastic plate 24, the slider 74 can be pushed to slide in the movable groove on the L-shaped plate 7 under the action of the pushing spring 73. Then, the movement of the slider 74 can make the pushing rod 71 push the fixing plate 72 to move, so that the fixing plate 72 is fixed to one side of the elastic plate 24, which can increase the fixing force on the elastic plate 24 to prevent the toothed plate 41 from being separated from the inner part of the limit rod 13 when the elastic plate 24 is deformed under the force, further increasing the fixing of the elastic plate 24, so that the toothed plate 41 is more firmly fixed to the other side of the limit rod 13. By fixing the limit rod 13, the fixing of the optical fiber distribution frame body 1 can be increased, and the displacement of the optical fiber distribution frame body 1 during operation is avoided. The stability of the optical fiber distribution frame body 1 is correspondingly increased, so that the optical signal is transmitted stably.

[0047] After the fiber optic distribution frame body 1 is fixed inside the shock absorbing box 2, when the fiber optic distribution frame body 1 is subjected to external forces, these forces first act on the bottom plate 11, and then the forces are transmitted to the elastic plates 1 3 and 2 4 through the contact points between the bottom plate 11 and the elastic plates 2 4 and 1 3, so that the elastic plates 1 3 and 2 4 are deformed by the forces, and the external forces can be converted into elastic potential energy, thereby reducing the vibration energy directly transmitted to the fiber optic distribution frame body 1 and the optical fiber cables inside it, and correspondingly maintaining the stability and reliability of the optical fiber connection, reducing the risk of optical fiber breakage or connection failure caused by vibration, and after the external vibration and impact are effectively absorbed by the elastic plate, the maintenance requirements of the fiber optic distribution frame body 1 and its internal equipment will be greatly reduced, thereby improving the overall operation efficiency of the equipment.

[0048] When the bottom plate 11 is driven to move by the elastic plate 24, the movement of the bottom plate 11 can be used to make the movable plate 61 move up and down with the elastic plate 24 and slide inside the fixed shell 6. Then, the movable plate 61 can move up and down to drive the fixed plate 72 to move, so that the fixed plate 72 is always fixed on one side of the elastic plate 24, avoiding the separation of the fixed plate 72 from the elastic plate 24 when the elastic plate 24 moves up and down, and correspondingly increasing the stability between the elastic plate 24 and the fixed plate 72, so that the toothed plate 41 and the limit rod 13 are better fixed together.

[0049] By setting the buffer pad 31, a buffering effect can be played on the limit rod 13 when the limit rod 13 moves to the top of the mounting plate 5, thereby avoiding collision between the limit rod 13 and the top of the mounting plate 5. Correspondingly, the protrusion set on the buffer pad 31 can increase the contact area between the limit rod 13 and the buffer pad 31, thereby increasing the impact force, improving the shock absorption effect, helping to release the buffering force, and reducing possible damage or deformation during the impact.

[0050] By providing the rubber strip 8 at the bottom of the elastic plate 1 3 and the elastic plate 2 4, when the elastic plate 1 3 and the elastic plate 2 4 are subjected to external force, the rubber strip 8 can absorb part of the impact force and reduce the energy directly transmitted to the elastic plate 1 3 and the elastic plate 2 4, thereby alleviating the burden on the elastic plate 1 3 and the elastic plate 2 4 and further increasing the service life of the elastic plate 1 3 and the elastic plate 2 4. Furthermore, by adding the rubber strip 8, the vibration amplitude can be further reduced and the shock absorption performance of the entire structure can be improved.

[0051] By movably inserting the fixing rod 81 into the mounting groove on the second elastic plate 4, when the rubber strip 8 is damaged, the fixing rod 81 can be pulled out from the second elastic plate 4 to replace the rubber strip 8.

[0052] 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.
