Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an optical fiber jumper detection device. Background Art

[0002] In daily life, optical fiber is used for long-distance information transmission because the loss of light in optical fiber is much lower than the loss of electricity in wire. Usually, the two terms optical fiber and optical cable are confused. Most optical fibers must be covered with several layers of protective structure before use. The covered cable is called optical cable. When wiring optical fiber, the optical fiber must be connected to the equipment, and a fiber jumper detector is needed to detect whether the jumper is qualified.

[0003] After searching, a utility model with Chinese patent publication number CN217304325U discloses a fiber optic jumper detection device, including a buffer mechanism and a heat dissipation mechanism arranged inside the buffer mechanism, the buffer mechanism includes a buffer box, one end of the buffer box is fixedly connected with a buckle, both sides of the inner wall of the buffer box are fixedly connected with mounting brackets, a detection component is arranged between two groups of the mounting brackets, and the detection component includes a detection shell fixedly connected between the two groups of the mounting brackets.

[0004] The above device achieves the effect of reducing impact force by setting up multiple buffer mechanisms. However, under the restriction of multiple buffer mechanisms, the detection shell will not be able to move in the horizontal direction. Therefore, when the device is subjected to lateral impact force, the buffering effect will be minimal, and there is room for improvement. Utility Model Content

[0005] The purpose of the utility model is to provide a fiber jumper detection device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fiber optic jumper detection device, comprising an outer box, characterized in that: an installation box is slidably inserted inside the outer box, a plurality of buffer components are installed inside the installation box, the buffer component comprises a sliding track arranged inside the installation box, four equidistantly distributed installation blocks are slidably connected inside the sliding track, a plurality of damping rods 2 are fixedly connected to the outer walls on one side of the four installation blocks close to each other, a spring 2 is sleeved on the outside of the plurality of damping rods 2, a detection box is fixedly connected to one end of the plurality of damping rods 2 close to each other, and the detection box is in contact with the inner wall of the bottom of the installation box.

[0007] As a further preferred embodiment of the technical solution, a plurality of damping rods 1 distributed at equal distances are fixedly connected to the outer wall of the bottom of the installation box and the inner wall of the bottom of the outer box, and a spring 1 is sleeved on the outside of each of the plurality of damping rods 1.

[0008] When the device is hit by external forces in different directions, the detection box can be effectively buffered, ensuring that the damage to the detection box when it is hit by external forces is greatly reduced. When the device is transported, if the device is hit by a lateral external force, since the detection box and the mounting block are connected to the damping rod 2, and the mounting block is installed in the sliding track, the detection box can drive the mounting block to move in the sliding track to ensure that the position of the detection box is not restricted. Under the action of inertia, the detection box will move in the opposite direction. At this time, the spring 2 in the force direction can buffer the movement of the detection box, and the damping rod 2 inside it can gradually reduce the impact force. If the device is hit by a longitudinal external force, the operating principle is the same as above. If the device is hit by an external force in the vertical direction, the detection box can drive the mounting box to slide in the outer box. Similarly, the spring 1 buffers the impact force, and the damping rod 1 can gradually weaken the impact force.

[0009] As a further preferred embodiment of the technical solution, a lifting assembly is installed on both sides of the outer box, and the lifting assembly includes an extension plate fixedly connected to the outer wall of one side of the outer box, and a screw rod is threadedly connected at both ends of the extension plate, and one end of the bottom of the two screw rods is rotatably connected to the same support block, and a pulley is fixedly sleeved on the bottom of the circumferential outer wall of the two screw rods, and the two pulleys are set with the same belt.

[0010] As a further preferred embodiment of the present technical solution, a second pulley is fixedly sleeved on the bottom of the circumferential outer wall of the two screw rods at one end, and the two pulleys are sleeved with the same second belt.

[0011] A screw rod is driven to rotate by the handle, and this screw rod can drive a pulley 1 connected to it to rotate synchronously. This pulley 1 can drive another screw rod to rotate synchronously through belt 1. The synchronous rotation of the two screw rods will move downward along the extension plate, and then the support block will also move to the bottom of the outer box. The rotating screw rod will also drive pulley 2 to rotate, and pulley 2 will drive another pulley 2 to rotate through belt 2. At this time, the other support block will also move synchronously to the bottom of the outer box.

[0012] As a further preferred embodiment of the technical solution, a stabilizing rod is slidably inserted in the middle of each of the two extension plates, and one end of the bottom of the two stabilizing rods is respectively fixedly connected to the top outer walls of the two support blocks.

[0013] As a further preferred embodiment of the present technical solution, the thread lead angle of the plurality of screw rods is smaller than the equivalent friction angle.

[0014] As a further preferred embodiment of the present technical solution, the outer walls of the bottoms of the two support blocks are both provided with anti-slip pads.

[0015] The utility model provides a fiber optic patch cord detection device, which has the following beneficial effects:

[0016] (1) The utility model provides a buffer assembly, a damping rod 1 and a spring 1, so that when the device is hit by external forces in different directions, the detection box can be effectively buffered, ensuring that the damage to the detection box when it is hit by external forces is greatly reduced. When the device is transported, if the device is hit by a lateral external force, since the detection box and the mounting block are together through the damping rod 2, and the mounting block is installed in the sliding track, the detection box can drive the mounting block to move in the sliding track, ensuring that the position of the detection box is not restricted. Under the action of inertia, the detection box will move in the opposite direction. At this time, the spring 2 in the force direction can buffer the movement of the detection box, and the damping rod 2 inside it can gradually reduce the impact force. If the device is hit by a longitudinal external force, the operating principle is the same as above. If the device is hit by an external force in the vertical direction, the detection box can drive the mounting box to slide in the outer box. Similarly, the spring 1 buffers the impact force, and the damping rod 1 can gradually weaken the impact force.

[0017] (2) The utility model sets a lifting assembly, and drives a screw rod to rotate through a handle. The screw rod can drive a pulley 1 connected to it to rotate synchronously. The pulley 1 can drive another screw rod to rotate synchronously through a belt. The synchronous rotation of the two screw rods will move downward along the extension plate, and then the support block will also move to the lower position of the outer box. The rotating screw rod will also drive the pulley 2 to rotate. The pulley 2 drives the other pulley 2 to rotate through the belt 2. At this time, the other support block will also move synchronously to the lower position of the outer box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 4 As shown, in the present embodiment, a fiber optic jumper detection device comprises an outer box 1, characterized in that: an installation box 505 is slidably inserted inside the outer box 1, a plurality of buffer components 5 are installed inside the installation box 505, the buffer component 5 comprises a sliding track 501 arranged inside the installation box 505, four equidistantly distributed installation blocks 502 are slidably connected inside the sliding track 501, a plurality of damping rods 503 are fixedly connected to the outer walls of the sides of the four installation blocks 502 close to each other, a spring 504 is sleeved on the outside of the plurality of damping rods 503, a detection box 2 is fixedly connected to the ends of the plurality of damping rods 503 close to each other, and the detection box 2 is in contact with the inner wall at the bottom of the installation box 505.

[0025] A plurality of damping rods 3 distributed at equal distances are fixedly connected to the bottom outer wall of the installation box 505 and the bottom inner wall of the outer box 1, and a spring 4 is sleeved on the outside of each of the plurality of damping rods 3.

[0026] If the device is subjected to a lateral external force collision, since the detection box 2 and the mounting block 502 are together through the damping rod 2 503, and the mounting block 502 is installed in the sliding track 501, the detection box 2 can drive the mounting block 502 to move in the sliding track 501, ensuring that the position of the detection box 2 is not restricted. Under the action of inertia, the detection box 2 will move in the opposite direction. At this time, the spring 2 504 in the force direction can buffer the movement of the detection box 2, and the damping rod 2 503 therein can gradually reduce the impact force. If the device is subjected to a longitudinal external force collision, the operating principle is the same as above. If the device is subjected to a vertical external force, the detection box 2 can drive the mounting box 505 to slide in the outer box 1. Similarly, the spring 1 4 buffers the impact force, and the damping rod 1 3 can gradually weaken the impact force.

[0027] like Figure 2 and Figure 3 As shown, a lifting assembly 6 is installed on both sides of the outer box 1, and the lifting assembly 6 includes an extension plate 601 fixedly connected to the outer wall of one side of the outer box 1, and a screw rod 602 is threadedly connected at both ends of the extension plate 601. One end of the bottom of the two screw rods 602 is rotatably connected to the same support block 603, and the bottom of the circumferential outer wall of the two screw rods 602 is fixedly sleeved with a pulley 604, and the two pulleys 604 are sleeved with the same belt 605.

[0028] A second pulley 606 is fixedly sleeved on the bottom of the circumferential outer wall of the two screw rods 602 at one end, and the two second pulleys 606 are sleeved with the same second belt 607.

[0029] A screw rod 602 is driven to rotate by the handle, and this screw rod 602 can drive a pulley 1 604 connected to it to rotate synchronously, and this pulley 1 604 can drive another screw rod 602 to rotate synchronously through a belt 1 605. The synchronous rotation of the two screw rods 602 will move downward along the extension plate 601, and then the support block 603 will also move to the lower position of the outer box 1, and the rotating screw rod 602 will also drive the pulley 2 606 to rotate, and the pulley 2 606 drives another pulley 2 606 to rotate through a belt 2 607, and at this time, the other support block 603 will also move synchronously to the lower part of the outer box 1.

[0030] like Figure 1 and Figure 2 As shown, a stabilizing rod 608 is slidably inserted in the middle of the two extension plates 601, and one end of the bottom of the two stabilizing rods 608 is respectively fixedly connected to the top outer wall of the two support blocks 603 to ensure that the state of the device is more stable.

[0031] like Figure 1 and Figure 2 As shown, the thread lead angles of the plurality of screw rods 602 are smaller than the equivalent friction angle, so that the position of the device will not change randomly after the height is adjusted.

[0032] like Figure 1 and Figure 2 As shown, the outer walls of the bottoms of the two support blocks 603 are both provided with anti-skid pads, so that the static friction between the support blocks 603 and the containing device is greater, thereby ensuring better stability of the device.

[0033] The utility model provides a fiber optic patch cord detection device, the specific working principle is as follows:

[0034] When the device is being transported, if the device is hit by a lateral external force, since the detection box 2 and the mounting block 502 are connected together through the damping rod 2 503, and the mounting block 502 is installed in the sliding track 501, the detection box 2 can drive the mounting block 502 to move in the sliding track 501, ensuring that the position of the detection box 2 is not restricted. Under the action of inertia, the detection box 2 will move in the opposite direction. At this time, the spring 2 504 in the force direction can buffer the movement of the detection box 2, and the damping rod 2 503 inside it can gradually reduce the impact force. If the device is hit by a longitudinal external force, the operating principle is the same as above. If the device is hit by an external force in the vertical direction, the detection box 2 can drive the mounting box 505 to slide in the outer box 1, and the spring 2 504 in the force direction can buffer the movement of the detection box 2, and the damping rod 2 503 inside it can gradually reduce the impact force. The spring 1 4 buffers the impact force, and the damping rod 1 3 can gradually weaken the impact force. If the height of the platform for placing objects is low, it is only necessary to drive a screw rod 602 to rotate through the handle, and this screw rod 602 can drive a pulley 1 604 connected to it to rotate synchronously. This pulley 1 604 can drive another screw rod 602 to rotate synchronously through a belt 1 605. The synchronous rotation of the two screw rods 602 will move downward synchronously along the extension plate 601, and then the support block 603 will also move to the lower position of the outer box 1, and the rotating screw rod 602 will also drive the pulley 2 606 to rotate, and the pulley 2 606 drives another pulley 2 606 to rotate through a belt 2 607. At this time, the other support block 603 will also move synchronously to the lower part of the outer box 1.

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