Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber bases, and specifically relates to a high-precision optical fiber base. Background Technique

[0002] The function of the optical fiber base is to support and fix the optical fiber so that it will not be affected by external forces during the installation process, ensuring that the optical signal can be transmitted stably and clearly. In the optical fiber communication system, the optical fiber is the main carrier for information transmission, and its performance directly affects the operation effect of the entire system. Therefore, in order to ensure that the optical fiber can work stably and transmit data effectively, the optical fiber base is particularly important.

[0003] When implementing this technical solution, at least the following defects still exist: Although the existing optical fiber base is installed and clamped through the dovetail groove provided in cooperation with the dovetail seat on the adjustment frame, the position of the optical fiber base cannot be limited after clamping, and it is inconvenient to fix and limit the fiber fixing chuck passing through in a linkage manner after clamping, so improvement is urgently needed. Therefore, we propose a high-precision optical fiber base. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-precision optical fiber base, which solves the problems raised in the background technique.

[0007] By adopting the above technical solution, during the clamping process, the hemispherical surface can be squeezed and pushed, so that the fixing block is pushed into the first accommodating cavity, and at the same time, the first airbag is squeezed, compressing the spring. Through the reaction force of the first airbag and the resilience of the spring, a reaction force to the right is applied to the fixing block, so that the hemispherical surface abuts against the outside of the dovetail seat, thereby limiting the position of the base body. Also, during the squeezing process of the first airbag, the positioning block abuts against the outside of the inserted fiber fixing chuck, thereby limiting the fiber fixing chuck, saving the trouble of using a knob structure to fix the fiber fixing chuck, and further facilitating the installation operation of the staff.

[0008] Optionally, the size of the fixed block is adapted to the size of the first accommodation cavity, and the fixed block is movably connected to the first accommodation cavity.

[0009] By adopting the above technical solution, it is convenient to cooperate the fixed block with the first accommodation cavity, so as to ensure that the fixed block moves left and right in the first accommodation cavity, and at the same time, the first airbag can be squeezed.

[0010] Optionally, a spring is fixedly installed in the inner cavity of the chute, and the other end of the spring is fixedly connected to the slider.

[0011] By adopting the above technical solution, it is convenient to drive the fixed block to reset through the arrangement of the spring.

[0012] Optionally, the volume of the first airbag is the same as the volume of the second airbag.

[0013] By adopting the above technical solution, it is convenient to complete the limitation of the optical fiber fixing chuck while ensuring the positioning of the base body.

[0014] Optionally, the air outlet end of the first airbag is communicated with a hose, and the other end of the hose is communicated with the air inlet end of the second airbag.

[0015] By adopting the above technical solution, it is convenient to transmit gas through the arrangement of the hose.

[0016] Optionally, the size of the slider is adapted to the size of the chute, and the slider is slidably connected to the chute.

[0017] By adopting the above technical solution, through the cooperation of the slider and the chute, the stability of the movement of the fixed block is ensured.

[0018] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:

[0019] Through the base body, dovetail groove, hemispherical surface, first accommodation cavity, first airbag, second airbag and hose provided in the technical solution of the present application, the hemispherical surface can be squeezed and pushed during the clamping process, so as to push the fixed block into the first accommodation cavity, and at the same time, the first airbag is squeezed, the spring is compressed, and through the reaction force of the first airbag and the resilience of the spring, a reaction force to the right is applied to the fixed block, so that the hemispherical surface abuts against the outside of the dovetail seat, thereby limiting the position of the base body. Also, during the extrusion of the first airbag, the positioning block abuts against the outside of the inserted optical fiber fixing chuck, so as to limit the optical fiber fixing chuck, eliminating the trouble of using a knob structure to fix the optical fiber fixing chuck, and further facilitating the installation operation of the staff.

[0025] Please refer to Figures 1-3 , the present utility model provides a technical solution: a high - precision optical - fiber base, including a base body 1. A slot 11 is opened in the middle of the base body 1, a dovetail groove 12 is opened at the lower end of the base body 1, a first accommodation cavity 22 is opened on one side of the dovetail groove 12, a fixed block 2 is arranged inside the first accommodation cavity 22, a hemispherical surface 21 is arranged on one side of the fixed block 2, and a slide groove 23 is opened at the lower end of the inner cavity of the first accommodation cavity 22;

[0026] A slide block 24 is fixedly installed at the lower end of the fixed block 2, a first airbag 26 is adhered to one side inside the first accommodation cavity 22, a second accommodation cavity 3 is opened on one side of the slot 11, a positioning block 31 is arranged inside the second accommodation cavity 3, a second airbag 32 is adhered to one side of the positioning block 31. The volume of the first airbag 26 is the same as the volume of the second airbag 32, which is convenient for ensuring that while the base body 1 is positioned, the optical - fiber fixing chuck is limited. The air - outlet end of the first airbag 26 is communicated with a hose 4, and the other end of the hose 4 is communicated with the air - inlet end of the second airbag 32, which is convenient for transmitting gas through the arrangement of the hose 4. The size of the slide block 24 is adapted to the size of the slide groove 23, and the slide block 24 is slidably connected with the slide groove 23. By the cooperation of the slide block 24 and the slide groove 23, the stability of the movement of the fixed block 2 is ensured.

[0027] The size of the fixed block 2 is adapted to the size of the first accommodation cavity 22, and the fixed block 2 is movably connected with the first accommodation cavity 22, which is convenient for ensuring that the fixed block 2 can move left and right inside the first accommodation cavity 22 through the cooperation of the fixed block 2 and the first accommodation cavity 22, and at the same time, the first airbag 26 can be squeezed.

[0028] A spring 25 is fixedly installed in the inner cavity of the chute 23, and the other end of the spring 25 is fixedly connected to the slider 24, which facilitates the reset of the fixed block 2 through the arrangement of the spring 25.

[0029] During installation, first insert the optical fiber fixing chuck into the slot 11, and then snap the dovetail groove 12 on the base body 1 onto the dovetail seat on the adjustment bracket. At the same time, during the snapping process, the hemispherical surface 21 will be squeezed and pushed, so as to push the fixed block 2 into the first accommodating cavity 22, and at the same time squeeze the first airbag 26 and compress the spring 25. Through the reaction force of the first airbag 26 and the resilience of the spring 25, a reaction force to the right is applied to the fixed block 2, so that the hemispherical surface 21 abuts against the outside of the dovetail seat, thereby limiting the position of the base body 1. At the same time, during the extrusion of the first airbag 26, the air in the first airbag 26 is discharged into the second airbag 32 through the hose 4, and the second airbag 32 expands to push the positioning block 31 to move to the right, so that the positioning block 31 abuts against the outside of the inserted optical fiber fixing chuck, thereby limiting the optical fiber fixing chuck, saving the trouble of using a knob structure to fix the optical fiber fixing chuck, and further facilitating the installation operation of the staff.
