DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0036] Example 1

[0037] See also Figure 1-2 A fiber optic detection device for optical fiber connection includes a housing 1, a protective shell 2 is installed at one end of the housing 1, a detection socket 3 is installed inside the protective shell 2, and an auxiliary device 4 is rotatably connected to one end of the protective shell 2. The auxiliary device 4 is used to assist the optical fiber head in inserting into the detection socket 3;

[0038] The auxiliary device 4 includes an outer shell 41 rotatably connected to one end of the protective shell 2. An airbag 42 is installed inside the outer shell 41, and the outer surface of the airbag 42 is coated with liquid. A flow box 43 is installed at one end of the protective shell 2. The flow box 43 wraps around the lower end of the outer shell 41 and the airbag 42. A support device 5 is installed at one end of the flow box 43. The support device 5 is used to support the optical fiber head.

[0039] One end of the airbag 42 is provided with an inclined surface 47 .

[0040] The flow box 43 stores lubricating liquid inside. By inflating the airbag 42 and rotating the airbag 42, the airbag 42 is constantly in contact with the lubricating liquid inside the flow box 43, so that the lubricating liquid adheres to the outer surface of the airbag 42. Then, when the optical fiber head needs to be inspected, the optical fiber head is pressed against the airbag 42. Since the inflated airbag 42 is soft, the airbag 42 will not damage the end face of the optical fiber head. Since one end of the airbag 42 is provided with a bevel 47, the optical fiber head is guided by the bevel 47 to slide toward the center of the circle of the airbag 42, and is lubricated by the lubricating liquid on the outer surface of the airbag 42. Thus, the optical fiber head can be quickly guided by the bevel 47 to move and insert into the inspection socket 3, so that the inspector no longer needs to accurately align the optical fiber head and the inspection socket 3 to connect the two. This improves the inspection efficiency and reduces the labor intensity of the inspector.

[0041] It should be noted that, since the airbag 42 rotates, the inflated airbag 42 rotates and rubs against the end face of the optical fiber head, thereby cleaning the end face of the optical fiber head through the airbag 42, thereby achieving automatic cleaning of the optical fiber head end face. Subsequently, the dirt adhering to the airbag 42 rotates into the interior of the flow box 43, so that the dirt comes into contact with the large amount of lubricating fluid inside the flow box 43, thereby cleaning the outer surface of the airbag 42.

[0042] It should be noted that a sealing plug is installed at the lower end of the circulation box 43, and the sealing plug is threadedly connected to the lower end of the circulation box 43. When the sealing plug is removed, the lubricating fluid and dirt inside the circulation box 43 will flow out from the circulation box 43, thereby replacing the lubricating fluid.

[0043] Example 2

[0044] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-2 The supporting device 5 includes a short shaft 51 installed at one end of the flow box 43. A rotating plate 52 is installed on the outer surface of the short shaft 51. The rotating plate 52 is used to abut against the optical fiber head.

[0045] When the optical fiber head is inserted into the detection socket 3, since one end of the optical fiber head is connected to an optical fiber line, the optical fiber line is long and heavy, and the optical fiber line may pull the optical fiber head downward, causing the optical fiber head to detach from the detection socket 3 and damage the detection socket 3. The operator is required to support the optical fiber head or the optical fiber line, so there is also an inconvenience in operation. To this end, the present application rotates a rotating plate 52 connected to one end of the circulation box 43, and by rotating the rotating plate 52, the rotating plate 52 is used to contact the optical fiber line, thereby reducing the optical fiber line pulling the optical fiber head downward.

[0046] Example 3

[0047] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-4, one end of the protective shell 2 is also provided with a movable groove, which passes through the protective shell 2 and the outer shell 41;

[0048] A support column 10 is installed inside the movable groove, and a first spring 16 is sleeved on the outer surface of the support column 10. A second ring 12 is slidably connected to one end of the support column 10, and an extension bar 13 is installed at one end of the second ring 12. A first ring 11 is installed at one end of the extension bar 13. A cleaning chamber 14 is provided between the first ring 11 and the second ring 12.

[0049] A cleaning device 6 is installed inside the protective shell 2, and the cleaning device 6 is used to spray and clean the outer surface of the optical fiber head;

[0050] The cleaning device 6 includes a circulation groove 67 arranged inside the protective shell 2.

[0051] according to Figure 4 As shown, the optical fiber head is guided to the first ring 11 by the inclined surface 47, so that the first ring 11 contacts the outer surface of the optical fiber head, and the end face of the optical fiber head is inserted into the cleaning cavity 14. Then, the optical fiber head is slid toward one end, and the first ring 11 is pushed toward one end by the optical fiber head, and air is sprayed into the cleaning cavity 14 by the annular groove 67, so that the end face of the optical fiber head is dried. In this way, the detection head at the detection socket 3 can accurately detect the end face of the optical fiber head and reduce repeated focusing of the detection head;

[0052] It should be noted that in order to allow all the air ejected from the annular flow groove 67 to flow to the end face of the optical fiber head, a cleaning chamber 14 is provided between the first ring 11 and the second ring 12, and the end face of the optical fiber head is located in the cleaning chamber 14, so that the air ejected from the annular flow groove 67 can flow to the cleaning chamber 14.

[0053] Example 4

[0054] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-5 There are several cleaning devices 6, and the cleaning devices 6 are arranged in a ring array around the axis of the protective shell 2;

[0055] The interior of the annular groove 67 is slidably connected to a sliding post 64 , and the first ring 11 is used to abut against the sliding post 64 ;

[0056] A storage slot 17 is also provided inside the protective shell 2;

[0057] The cleaning device 6 further includes a transmission hole 61, a pressure relief groove 62, and a communication hole 66 provided inside the protective shell 2. The transmission hole 61 is connected to the pressure relief groove 62, and the pressure relief groove 62 is connected to the communication hole 66.

[0058] A sealing plug 63 is installed at one end of the sliding column 64, and the sealing plug 63 is used to seal the circulation groove 67. The sliding column 64 is connected to the protective shell 2 through a fifth spring 65;

[0059] The pressure relief grooves 62 of the plurality of cleaning devices 6 are connected through the communication hole 66;

[0060] The transmission hole 61 is communicated with the storage tank 17 .

[0061] according to Figure 4 and Figure 5 As shown, a plurality of cleaning devices 6 are installed inside the protective shell 2, so that the end face of the optical fiber head can be cleaned by spraying air in all directions through the circulation grooves 67 of the plurality of cleaning devices 6;

[0062] When the optical fiber head pushes the first ring 11 to slide toward the detection socket 3, the first ring 11 hits the sliding post 64 of the first cleaning device 6, so that the sliding post 64 slides to the left, and the sliding post 64 drives the sealing plug 63 to slide toward the inside of the pressure relief groove 62, so that the pressure relief groove 62 is connected with the circulation groove 67. At this time, the air in the storage groove 17, the transmission hole 61, and the pressure relief groove 62 will flow to the circulation groove 67 and be ejected. Figure 4 As shown, a through hole 48 is provided at one end of the outer shell 41. The airbag 42 is pulled to contract by a third spring 49, so that the gas in the airbag 42 flows to the through hole 48, and the through hole 48 flows to the circulation groove 15. The circulation groove 15 transmits the air in the airbag 42 to the storage groove 17, so that the storage groove 17 is always filled with high-pressure air.

[0063] It should be noted that every two pressure relief grooves 62 are connected through a communication hole 66, so that the air in the airbag 42 can be ejected from any of the circulation grooves 67;

[0064] When the optical fiber head drives the first ring 11 to move to the sliding post 64 of the second cleaning device 6, the sliding post 64 of the second cleaning device 6 squeezes the second sliding post 64 and slides to the left, so that the second sliding post 64 sprays air to clean the end face of the optical fiber head. In this way, the end face of the optical fiber head is cleaned repeatedly, thereby improving the detection accuracy.

[0065] After the detection is completed, the first ring 11 is pushed to reset by the first spring 16 on the outer surface of the support column 10, and a button is installed on the outer surface of the first ring 11, and an inflation port is installed at the storage groove 17. When the button at the storage groove 17 is squeezed on the protective shell 2, the button sends a signal to make the air pump inflate the inflation port to fill the storage groove 17 and the airbag 42, so that the airbag 42 can expand again, which is convenient for guiding the optical fiber head through the airbag 42 next time.

[0066] Example 5

[0067] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-5, a third spring 49 is installed inside the airbag 42, and one end of the third spring 49 is connected to one end of the airbag 42;

[0068] A through hole 48 is provided at one end of the outer shell 41, and a flow groove 15 is further provided inside the protective shell 2. The through hole 48, the flow groove 15 and the storage groove 17 are connected;

[0069] An extrusion plate 56 is slidably connected to the inner portion of the outer shell 41. The extrusion plate 56 is connected to the outer shell 41 via a fourth spring 57. One end of the extrusion plate 56 is used to squeeze the airbag 42.

[0070] A cable 53 is further mounted on one end of the extrusion plate 56. A guide wheel 55 is mounted on the upper end of the outer shell 41. The upper end of the cable 53 abuts against the outer surface of the guide wheel 55 and is connected to one end of the rotating plate 52. A spring 54 is mounted on the lower end of the rotating plate 52. One end of the spring 54 is connected to one end of the outer shell 41.

[0071] A second spring 18 is installed at one end of the housing 1, and one end of the second spring 18 is connected to one end of the protective shell 2, and one end of the protective shell 2 is used to be inserted into the interior of the housing 1;

[0072] A gear ring 45 is installed on the outer surface of the outer shell 41 , a motor 44 is installed on the upper end of the protective shell 2 , and a gear 46 is installed on one end of the motor 44 , and the gear 46 is meshed with the gear ring 45 .

[0073] according to Figure 5 As shown, one end of the squeezing plate 56 contacts the airbag 42. Therefore, when the airbag 42 rotates, the squeezing plate 56 scrapes the dirt on the outer surface of the airbag 42, so that the dirt is separated from the airbag 42, thereby improving the cleanliness of the outer surface of the airbag 42 and preventing the airbag 42 from contaminating the outer surface of the optical fiber head.

[0074] When the airbag 42 is deflated, the fourth spring 57 pulls the extrusion plate 56 to slide toward the inside of the outer shell 41, so that the extrusion plate 56 squeezes the airbag 42, thereby increasing the gas pressure inside the airbag 42 and thus increasing the air pressure injection intensity;

[0075] When the extrusion plate 56 slides toward one end, the extrusion plate 56 pulls the cable 53, causing the cable 53 to pull the rotating plate 52 to slide toward one end. In this way, the cable 53 pulls one end of the rotating plate 52 upward, so that the rotating plate 52 contacts the lower end of the optical fiber line, so that the rotating plate 52 can automatically support the optical fiber line.

[0076] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
