The optical distribution frame includes: a distribution frame body 1, a mounting bracket 11 fixedly mounted on the distribution frame body 1, and multiple fixed boxes 12 arranged in a row fixedly mounted on the mounting bracket 11. Module boxes 14 are slidably connected to each of the multiple fixed boxes 12. Two cable passages 13 are opened at the bottom of the distribution frame body 1, and the two cable passages 13 are respectively located at the front and rear ends of the fixed boxes 12. A cable through-hole 17 is also opened at the bottom of the distribution frame body 1, and the two cable passages 13 are connected through the cable through-hole 17. The multiple fixed boxes... Each box 12 is equipped with a limiting mechanism 2; the limiting mechanism 2 includes two fixed tubes 21, both fixed tubes 21 are fixedly connected to one side of the fixed box 12, and both fixed tubes 21 penetrate the side wall of the fixed box 12 and extend to the inner wall of the fixed box 12. Two fixed cylinders 22 are fixedly connected to the module box 14. The inside of each fixed cylinder 22 is elastically connected to a limiting post 23 through a return spring 26. A top block 24 is inserted into each of the two fixed tubes 21, and the upper end of each top block 24 is fixedly connected to a button 25. The button 25 is elastically connected to the side wall of the fixed box 12 through another return spring 26.

[0023] It should be noted that the module box 14 in this utility model is used for the assembly of optical cables. Multiple module boxes 14 are used for the connection and installation of different optical cables without interference. When it is necessary to assemble the optical cables in the module box 14, by pressing the button 25 on one side of the fixed box 12, the top block 24 moves in the fixed tube 21, and the limiting post 23 is moved out of the fixed tube 21 and retracted into the fixed cylinder 22, so that the module box 14 can be taken out from the fixed box 12 and the optical cables can be assembled on the module box 14. The module box 14 can be pulled back and forth, so that it can be taken out from the front or the back for assembly as needed. When it is necessary to assemble the front and rear optical cables of the module box 14, but the optical cables at the front and rear ends are forgotten to pass through the fixed box 12, the module box 14 can be installed from the bottom of the patch panel body 1 through the cable passage 17. That is, the module box 14 is moved from the bottom of the patch panel body 1 through the cable passage 13 to the top of the patch panel body 1, and the optical cables pass through the cable passage 17, so that the module box 14 can be reassembled. When the module box 14 is inserted into the fixed box 12, the limiting post 23 moves to the fixed tube 21 and is locked into the fixed tube 21 by the elastic force of the lower return spring 26, thus restricting the module box 14. The module box 14 in this utility model can be pulled out from the front or back, and can be taken out from the front or back for optical wiring assembly according to actual needs, making the operation more flexible and convenient, and improving the convenience and efficiency of assembly. When the optical wiring at the front and rear ends is forgotten to pass through the fixed box 12, the module box 14 can be installed from the bottom of the patch panel body 1 through the cable passage 17, that is, the module box 14 is moved from the bottom to the top, the optical wiring passes through the cable passage 17, and then the module box 14 is inserted into the fixed box 12, which effectively avoids assembly problems caused by negligence and reduces the trouble of rework. Multiple module boxes 14 are used for the docking installation of different optical wiring, which are independent of each other and do not interfere with each other, which is conducive to improving the stability and reliability of the optical patch panel and facilitates management and maintenance.

[0024] The limiting mechanism 2 is located on one side of the fixed box 12, which improves the overall aesthetics of the device.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 Each of the two cable ports 13 is fixedly connected to a row of reinforcing plates 15;

[0026] It should be noted that by setting the reinforcing plate 15, the overall strength of the main body 1 of the patch panel is improved. At the same time, the reinforcing plate 15 divides the cable outlet 13 and separates the assembly lines of different module boxes 14.

[0027] In the embodiments of this utility model, please refer to Figure 2 Each of the multiple cable outlets 17 is rotatably connected to a baffle 18, and a row of limit blocks 19 is rotatably connected to the bottom of the main body 1 of the patch panel, and the limit blocks 19 are fitted to the bottom of the baffle 18.

[0028] It should be noted that: the baffle 18 closes the cable passage 17, and the limit block 19 restricts the baffle 18 so that the baffle 18 cannot rotate downward. By rotating the limit block 19 away from the baffle 18, the baffle 18 can rotate. Since the bottom of the module box 14 is located at the cable passage 17, if there were no baffle 18, the bottom of the module box 14 would be exposed at the cable passage 17. The baffle 18 covers the bottom of the module box 14, thus protecting the module box 14.

[0029] In the embodiments of this utility model, please refer to Figure 2 The bottom of the patch panel body 1 is equipped with two sets of pads 16, and the height of the pads 16 is greater than the height of the limit block 19.

[0030] It should be noted that when the patch panel body 1 is laid flat alone, the patch panel body 1 is raised by the pads 16 to prevent the optical cables passing through the cable outlet 13 from being squeezed and damaged by the ground.

[0031] The reset spring 26 located on the fixed box 12 is covered with a rubber sleeve, and the upper and lower ends of the rubber sleeve are fixedly connected to the fixed box 12 and the button 25 respectively; the rubber sleeve protects the exposed reset spring 26.

[0032] A strip-shaped rubber pad is fixedly installed on the inner wall of the fixing box 12, and the strip-shaped rubber pad is fitted to the module box 14; when the module box 14 is located in the fixing box 12, the strip-shaped rubber pad improves the connection stability between the module box 14 and the fixing box 12.

[0033] The working principle of the optical distribution frame with front and rear pull-out module box provided by this utility model is as follows:

[0034] The module box 14 in this utility model is used for the assembly of optical distribution cables. Multiple module boxes 14 are used for the docking and installation of different optical distribution cables without interference, which helps to improve the stability and reliability of the optical distribution frame and facilitates management and maintenance. When it is necessary to assemble the optical distribution cables in the module box 14, by pressing the button 25 on one side of the fixed box 12, the top block 24 moves in the fixed tube 21, and the limiting post 23 is moved out of the fixed tube 21 and retracted into the fixed cylinder 22, so that the module box 14 can be taken out from the fixed box 12 and the optical distribution cables can be assembled on the module box 14. The module box 14 can be pulled back and forth, which makes it convenient to take it out from the front or the rear for assembly line assembly as needed, making the operation more flexible and convenient, and improving the convenience and efficiency of assembly. When assembling the optical wiring, if one end of the optical wiring is forgotten to pass through the fixed box 12, the module box 14 can be installed from the bottom of the patch panel body 1 through the cable passage 17. That is, the module box 14 is moved from the bottom of the patch panel body 1 to the top of the patch panel body 1 through the cable passage 13, and the optical wiring passes through the cable passage 17. Then the module box 14 can be reinserted into the fixed box 12. When the module box 14 is inserted into the fixed box 12, when the limiting post 23 moves to the fixed tube 21, the limiting post 23 is locked into the fixed tube 21 under the elastic force of the lower return spring 26, which restricts the module box 14 and effectively avoids assembly problems caused by negligence, reducing the trouble of rework. Among them, the limiting mechanism 2 is located on one side of the fixed box 12, which improves the overall aesthetics of the device.
