DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] First embodiment:

[0024] See also Figure 1 to Figure 4 ,in Figure 1 is a side view of the first embodiment of the utility model, Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 The cross-sectional view of the BB line. Figure 4 The utility model Figure 2 Sectional view along the CC line.

[0025] The utility model provides an optical fiber taper device, including two convex blocks 101, a base 102 and a transmission mechanism, wherein the transmission mechanism includes an auxiliary rotating assembly, a bidirectional screw 111 and a motor 112, and the auxiliary rotating assembly includes a driving gear 115, a driven gear 116 and a mounting frame 117. The above-mentioned scheme solves the technical problem that in the above-mentioned structure, two cylinders are used to make the positions where two optical fibers need to be connected conflict with each other, and there is a hot-melt area just below the two optical fibers that are mutually abutted, and since it is impossible to accurately ensure that the pushing distances of the two cylinders are consistent, it is easy to cause the position where the two optical fibers are mutually abutted to deviate from the hot-melt area, thereby affecting the subsequent connection.

[0026] According to this specific embodiment, the convex block 101 is provided with a vertical rod 103, the vertical rod 103 is provided with a mounting tube 104, the mounting tube 104 is provided with a pressing mechanism 105, the convex block 101 has a threaded groove 106, the upper end surface of the base 102 has a convex groove 107, the front end surface of the base 102 is provided with a hot melt mechanism 108, the rear end surface of the base 102 is provided with a video recorder 109 and a display screen 110, the two convex blocks 101 are respectively connected to the base 102 in a sliding manner, and are symmetrically arranged in the convex groove 107, and ... The optical fibers to be tapered are respectively pressed and fixed in the two mounting tubes 104, and the positions where the two optical fibers need to be connected are arranged relative to each other. When passing through the transmission mechanism, the two convex blocks 101 move in a direction approaching each other, so that the two optical fibers to be tapered are in contact and pressed tightly. At this time, the hot-melt mechanism 108 generates high temperature to melt the two upper optical fibers to be tapered together, so that light can be coupled from one optical fiber to another, and the optical fiber taper work is completed. This process can be recorded by the video recorder 109 above and fed back by the display screen 110 via the transmission line, so that the optical fiber taper work can be recorded, observed and saved in real time.

[0027] Among them, one end of the bidirectional screw 111 has a polygonal groove 113, the output end of the motor 112 is provided with a polygonal rod 114, the auxiliary rotation assembly is arranged on the outside of the base 102, and is also located at one end of the bidirectional screw 111, the bidirectional screw 111 is rotatably connected to the base 102 through a bearing, and is located in the convex groove 107, the bidirectional screw 111 is also threadedly connected to the corresponding convex block 101, and is located between the two convex blocks 101, and is also located in the thread groove 106, the motor 112 is transmission-connected to the bidirectional screw 111, and is located at the other end of the bidirectional screw 111, and the polygonal rod 114 is located in the polygon shaped groove 113, the motor 112 is fixedly connected to the base 102 by bolts and is located on the side of the base 102 away from the auxiliary rotating assembly. The setting of the bidirectional screw 111 can facilitate the two convex blocks 101 to move at the same speed, thereby avoiding the position where the two optical fibers abut against each other deviating from the hot-melt area, and thus will not affect the subsequent connection of the two optical fibers. The setting of the polygonal rod 114 and the polygonal groove 113 can facilitate the quick disassembly and assembly of the motor 112. At the same time, the auxiliary rotating assembly can facilitate the subsequent maintenance of the motor 112 to play the role of assisting the rotation of the bidirectional screw 111, so that the device can be used normally.

[0028] Secondly, a rotating disk 118 is provided on the driving gear 115, and the driving gear 115 is rotatably connected to the mounting frame 117 and is located in the mounting frame 117. The driven gear 116 is rotatably connected to the mounting frame 117 and is located at one end of the mounting frame 117 away from the driving gear 115, and the driving gear 115 is also meshed with the driven gear 116, and the driven gear 116 is fixedly connected to the bidirectional screw 111 and is located at one end of the bidirectional screw 111. The mounting frame 117 is fixedly connected to the base 102 and is located on the outside of the base 102. By rotating the rotating disk 118, the rotating disk 118 transmits the driving gear 115, and the driving gear 115 is meshed with the driven gear 116. The bidirectional screw 111 rotates under the action of the driven gear 116, so that the two convex blocks 101 can move.

[0029] Again, the volume of the driven gear 116 is many times that of the driving gear 115. Transmitting the driven gear 116 through the smaller radius of the driving gear 115 means that the torque generated is smaller under the condition of equal input force, and the larger radius of the driven gear 116 can convert this smaller torque into a larger torque output, thereby saving effort.

[0030] When the utility model is used to make two optical fibers collide with each other, by starting the motor 112, the motor 112 drives the bidirectional screw 111 under the action of the polygonal rod 114 and the polygonal groove 113, and the two convex blocks 101 move in a direction close to each other under the action of the threaded groove 106, so that the two optical fibers need to be connected to collide with each other, thereby avoiding the deviation of the position where the two optical fibers are against each other from the hot-melt area, and thus will not affect the subsequent connection of the two optical fibers. In this way, the technical problem that two cylinders are used in the above-mentioned structure to make the positions where the two optical fibers need to be connected collide with each other, and the hot-melt area is directly below the two optical fibers that are against each other, and since it is impossible to accurately ensure that the pushing distance of the two cylinders is consistent, it is easy to cause the position where the two optical fibers are against each other to deviate from the hot-melt area, thereby affecting the subsequent connection, is solved.

[0031] The second embodiment is:

[0032] Based on the first embodiment, please refer to Figure 5 to Figure 7 ,in Figure 5 It is a three-dimensional stereogram of the second embodiment of the utility model. Figure 6 is a side view of the second embodiment of the utility model, Figure 7 The utility model Figure 6 Sectional view along line DD.

[0033] The utility model provides an optical fiber taper device, which also includes multiple support members, wherein the support members include an anti-slip pad 201, a fixed screw 202 and a threaded cylinder 203, the pressing mechanism 105 includes a pressing plate 204, a pulling plate 205 and two connecting rods 206, and the hot melt mechanism 108 includes a flamethrower 208, an electric telescopic rod 209 and a vertical plate 210.

The fixing screw 202 is threadedly connected to the threaded barrel 203 and is located inside the threaded barrel 203. The threaded barrel 203 is fixedly connected to the base 102 and is located below the base 102. The anti-slip pad 201 can be used to improve the grip, thereby preventing the threaded barrel 203 from slipping. The provision of the fixing screw 202 can facilitate the subsequent replacement of the damaged anti-slip pad 201.

[0035] The connecting rod 206 is provided with a tension spring 207, the lower pressure plate 204 is fixedly connected to the corresponding connecting rod 206, and is located at one end of the two connecting rods 206, and is also located in the mounting tube 104, the pulling plate 205 is fixedly connected to the corresponding connecting rod 206, and is located at the other end of the two connecting rods 206, and is also located above the mounting tube 104, the two connecting rods 206 are respectively slidably connected to the mounting tube 104, and penetrate the mounting tube 104. The outer side of the installation tube 104 and the tension spring 207 are welded between the installation tube 104 and the pulling plate 205. By pulling the pulling plate 205, the pulling plate 205 drives the two connecting plates to move upward, and the two connecting rods 206 pull the lower pressure plate 204 upward, thereby increasing the gap in the installation tube 104. At this time, the optical fiber can be placed therein, and then the pulling plate 205 is relaxed. The lower pressure plate 204 automatically presses the optical fiber under the action of the tension spring 207.

[0036] Secondly, the flamethrower 208 is fixedly connected to the electric telescopic rod 209 and is located at the output end of the electric telescopic rod 209.

The vertical plate 210 is fixedly connected to the base 102 and is located at the front end surface of the base 102. The electric telescopic movement can facilitate the control of the distance between the flamethrower 208 and the position where the two optical fibers conflict with each other, thereby improving the hot melting effect.

[0037] When using an optical fiber taper device according to the present embodiment, the gripping force can be improved by the anti-skid pad 201, thereby preventing the threaded tube 203 from slipping. The setting of the fixing screw 202 can facilitate the subsequent replacement of the damaged anti-skid pad 201. The pulling plate 205 is pulled to make the pulling plate 205 drive the two connecting plates to move upward. The two connecting rods 206 pull the lower pressure plate 204 upward, thereby increasing the gap in the installation tube 104. At this time, the optical fiber can be placed therein, and then the pulling plate 205 is relaxed. The lower pressure plate 204 automatically presses the optical fiber under the action of the tension spring 207. The electric extension can facilitate the control of the distance between the flamethrower 208 and the position where the two optical fibers conflict with each other, thereby improving the hot melting effect.
