Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fixed frame, especially in a kind of multi-hole position optical fiber distribution board fixed frame. BACKGROUND

[0002] Optical fiber distribution board is also called optical fiber distribution frame, and it is the key equipment for managing and connecting optical fiber line in optical fiber communication system. It is mainly used for the termination and distribution of local main optical cable in optical fiber communication system, and conveniently realizes the connection, distribution and scheduling of optical fiber line. The optical fiber distribution board needs a front fixed frame to fix the external cable when in use.

[0003] Although the existing front fixed frame can clamp the cable through the cooperation of the fixing seat and the pressing plate, there are still other problems in the use process, such as poor fixing effect, and the pressing plate clamping mode is difficult to control the force. If the pressing force is too large, it is easy to cause the cable sheath to be damaged, otherwise, if the pressing force is too small, it is difficult to play a fixed role, and the flexibility is poor. Moreover, the anti-collision protection effect is poor. After the fixed frame is installed, the front end is in an extended state. When the fixed frame is impacted by external objects, the force will be transmitted to the distribution board shell connected thereto, which is easy to deform and damage due to collision, and the safety is low. In order to solve the above problems, the present application provides a multi-hole position optical fiber distribution board fixed frame. SUMMARY

[0004] The utility model aims at providing a kind of multi-hole position optical fiber distribution board fixed frame, solve the problem that the fixing effect of existing fixed frame is poor and does not have the function of anti-collision buffer.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a kind of multi-hole position optical fiber distribution board fixed frame, including fixed frame, the inside of the fixed frame is provided with limiting plate, the top of the limiting plate is equipped with wire slot, the both sides of the limiting plate are welded with threaded rod, the both sides of the fixed frame are equipped with sliding slot, the other end of the threaded rod extends to the outside of sliding slot and is connected with nut by screw thread, the front of the fixed frame is provided with buffer plate, the both sides of the fixed frame are bolted with fixed cylinder, the inside of the fixed cylinder is provided with connecting block, connecting rod is installed between the front of the connecting block and the buffer plate, and the back of the connecting block and the fixed cylinder are bolted with buffer spring by spring fixing sheet.

[0006] The above technical scheme can realize good fixing effect, improve the anti-pulling effect of cable end, and has good stability and flexibility. At the same time, it can have the function of anti-collision buffer, reduce the impact on the product, prolong the service life of the equipment, and has high practicability.

[0007] The utility model is further provided as follows: spring washer is sleeved on the surface of the threaded rod.

[0008] By adopting the above technical solution and setting the spring washer, the fixing effect of the nut on the limiting plate after tightening can be improved.

[0009] The present invention is further configured such that mounting holes are provided on both sides of the fixing frame.

[0010] By adopting the above technical solution, the installation holes make it easy for personnel to fix the fixing frame to the wiring panel housing with screws, reducing the trouble of temporary drilling.

[0011] The present invention is further configured such that the number of the through slots is the same as the number of ports on the fiber optic distribution panel.

[0012] The present invention is further configured such that: a guide rod is installed on one side of the connecting block, a through groove is opened on one side of the fixing cylinder, and the other end of the guide rod extends to the outside of the through groove.

[0013] By adopting the above technical solution, the connecting block can be limited by the setting of guide rod and through groove, so as to prevent the connecting block from tilting when it moves inward under force.

[0014] The present invention is further configured such that both the threaded rod and the nut are made of stainless steel.

[0015] Using the above technical solutions, the threaded rod and nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0016] The present invention is further configured such that the buffer spring is made of carbon spring steel.

[0017] Using the above technical solution, the buffer spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model first uses screws to pass through the mounting holes to fix the fixing frame to the wiring panel. After the fixing frame is installed, the end of the external cable is inserted into the port at the front of the wiring panel. After all the cable ends are connected, the cable body is placed in the through groove and pulled straight out. Then, the limiting plate is pushed inward to fit against the cable end. Finally, the nut is tightened. This can achieve a good fixing effect, improve the anti-pull effect at the cable end, and provide good stability and flexibility.

[0020] 2. This utility model utilizes the principle that when the buffer plate is impacted, it causes two connecting rods to move inward. As the connecting rods move inward, they, in conjunction with the guide rod and the through groove, cause the connecting block to move as well. When the connecting block moves inward, it compresses the buffer spring, causing it to contract and deform. When the buffer spring contracts and stores energy, it absorbs and cancels out the force, thus providing an anti-collision buffer function, reducing the impact of impacts on the product, extending the service life of the equipment, and demonstrating high practicality.

The other end of the threaded rod 4 extends to the outside of the sliding groove 5 and is threadedly connected to a nut 6. The mounting frame 1 is fixed to the distribution panel by first passing screws through the mounting holes 12. After the mounting frame 1 is installed, the end of the external cable is inserted into the port at the front of the distribution panel. After all the cable ends are inserted, the cable body is placed in the cable passage groove 3 and pulled straight outward. Then, the limiting plate 2 is pushed inward to fit against the cable end. Finally, the nut 6 is tightened. This method achieves good fixing effect, improves the anti-pull effect at the cable end, and provides good stability and flexibility.

[0028] refer to Figure 2 A spring washer is slidably fitted onto the surface of the threaded rod 4. The spring washer improves the fixing effect of the nut 6 on the limiting plate 2 after tightening.

[0029] refer to Figure 1 andFigure 2 Mounting holes 12 are provided on both sides of the fixing frame 1. The mounting holes 12 make it easy for personnel to fix the fixing frame 1 to the wiring panel housing with screws, reducing the trouble of temporary drilling.

[0030] refer to Figure 1 and Figure 2 The number of cable trays 3 is the same as the number of ports on the fiber optic distribution panel.

[0031] refer to Figure 1 and Figure 2 Both the threaded rod 4 and the nut 6 are made of stainless steel, and have the characteristics of high strength, low density and excellent corrosion resistance.
