[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6 The utility model provides a technical solution: an optical fiber device for deploying an optical fiber network, comprising a protective shell 1, an optical fiber interface 2, a positioning protective plate 3, a communicating opening 4, a linkage extrusion block 5, a limiting push block 6, a positioning card block 7, an air guide piston column 8, a communicating air groove 9, a supporting air bag 10, a telescopic connecting arm 11, a limiting bottom block 12, a buffer support seat 13 and a damping friction block 14. The protective shell 1 is provided with an optical fiber interface 2 on its rear surface. A spring is connected between the end of the positioning protective plate 3 away from the limiting push block 6 and the protective shell 1. The communicating opening 4 is a semicircular design. The communicating opening 4 is arranged corresponding to the optical fiber interface 2. When using this device, first, by pushing the limiting push block 6 horizontally, the inclined surface of the limiting push block 6 pushes the linkage extrusion block 5, and the linkage extrusion block 5 drives the positioning protective plate 3 to move vertically. After the two positioning protective plates 3 slide and separate, it is convenient to connect the optical fiber interface 2 on the surface of the protective shell 1. Then, the limiting push block 6 is released, and the spring on the surface of the positioning protective plate 3 pushes it to slide back to its original position.

[0031] The rear surface of the protective shell 1 is slidingly connected with two positioning protective plates 3, and a connecting opening 4 is provided on the surface of the positioning protective plate 3. A baffle is provided on the rear surface of one end of the protective shell 1, and the surface of the baffle on the rear surface of the protective shell 1 is slidingly connected with a limiting push block 6. A spring is connected between the limiting push block 6 and the protective shell 1, and the outer surface of the limiting push block 6 facing the positioning protective plate 3 is inclined. The ends of the two linkage extrusion blocks 5 facing each other are arc-shaped. The linkage extrusion block 5 and the limiting push block 6 are arranged vertically. The length of the positioning block 7 is greater than the depth of the groove of the positioning protective plate 3. After the two positioning protective plates 3 slide, they approach and fit together, and the wiring harness is limited and protected through the connecting opening 4 on the surface. At the same time, the positioning blocks 7 on the inner wall of the groove of the positioning protective plate 3 are plugged into each other, so that the positioning block 7 is engaged and positioned through the spherical design, which improves the stability of the positioning protective plate 3 after fitting.

[0032] The positioning guard plate 3 is fixedly connected to the linkage extrusion block 5 on one end surface of the limit push block 6, and the two positioning guard plates 3 facing each other are provided with grooves, and the inner wall of the groove of the positioning guard plate 3 is fixedly connected with a positioning block 7, and the inner wall of the groove of the positioning guard plate 3 is slidably connected with an air guide piston column 8. The facing ends of the two positioning blocks 7 are spherical in design, and the two positioning blocks 7 are staggered left and right. The two positioning blocks 7 form a snap connection with each other, and the air guide piston column 8 is correspondingly arranged. A spring is connected between the air guide piston column 8 and the positioning guard plate 3, and a connecting air groove 9 is opened between the air guide piston column 8 and the support airbag 10. After the two positioning guard plates 3 are in contact, the positioning block 7 will push the air guide piston column 8, so that the air guide piston column 8 is pushed and the support airbag 10 is inflated through the connecting air groove 9, so that the support airbag 10 is inflated and fits the surface of the wiring harness, reducing gaps while preventing impurities from entering, and is beneficial to supporting the wiring harness and increasing the buffering protection performance.

[0033] The inner wall of the communicating opening 4 is fixed with a supporting airbag 10, and the lower surface of the protective shell 1 is fixedly connected with a telescopic connecting arm 11, and the lower surface of the telescopic connecting arm 11 is fixed with a limiting bottom block 12. The outer surface of the telescopic connecting arm 11 and the limiting bottom block 12 are installed with a buffer support seat 13, and the inner wall of the cavity of the buffer support seat 13 is slidably connected with a damping friction block 14. The telescopic connecting arm 11 and the limiting bottom block 12 are both slidably connected with the buffer support seat 13, and a spring is connected between the limiting bottom block 12 and the buffer support seat 13. The side surface of the limiting bottom block 12 is inclined, and the buffer support seat 13 is hollow. The inner wall of the cavity is designed to be inclined, and a spring is connected between the buffer support seat 13 and the damping friction block 14. The damping friction block 14 is set horizontally, and one end of the damping friction block 14 is designed to be arc-shaped. When the device is impacted, the telescopic connecting arm 11 and the limiting bottom block 12 slide down, which facilitates the spring on the bottom surface of the buffer support seat 13 to buffer. As the telescopic connecting arm 11 and the limiting bottom block 12 rise, the damping friction blocks 14 on both sides slide horizontally against the inclined surface of the limiting bottom block 12, which facilitates damping of the limiting bottom block 12, thereby allowing the device to buffer the impact force.

[0034] Working principle: When using the fiber optic equipment deployed in the fiber optic network, the limiting push block 6 is pushed to drive the linkage extrusion block 5 and the positioning protective plate 3 to slide, which is convenient for wiring the fiber optic interface 2. Then the spring on the surface of the positioning protective plate 3 pushes it to slide and reset, so that the connecting opening 4 limits the wiring harness, and the positioning card blocks 7 arranged oppositely are engaged with each other. At the same time, the positioning card block 7 pushes the air guide piston column 8 to inflate the support airbag 10 from the connecting air groove 9, which is convenient for the support airbag 10 to expand and support. The impact force is buffered by sliding the telescopic connecting arm 11 and the limiting bottom block 12, so that the damping friction block 14 on the inner wall of the buffer support seat 13 buffers the friction damping of the limiting bottom block 12, thereby increasing the overall practicality.

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