[0028] Embodiment 1
[0029] Refer to Figure 1 - Figure 6, which is the first embodiment of the present utility model, provides a distribution box. This device includes a bearing unit 100, which includes a bottom plate 101 and a first slot 106 provided on the bottom surface of the bottom plate 101; a combination unit 200, including a top plate 201 provided on the bottom plate 101 and a second slot 204 provided inside the top plate 201; and a limiting unit 300, including a bolt column 301 provided on the first slot 106, a limiting component 302 provided on the bolt column 301, a connecting column 303 provided on the bolt column 301, and a rotating column 304 provided on the connecting column 303. Through multiple groups of the limiting unit 300, it is convenient for the staff to arbitrarily allocate the space size inside the bottom plate 101 according to the number and size of the fiber optic sensors to be installed, thus facilitating the staff to install and arrange the wires, and increasing the comfort of use for the staff.
[0030] Among them, a first clamping column 305 corresponding to the second slot 204 is provided at the top of the rotating column 304. By clamping the first clamping column 305 with the second slot 204 at the inner top of the top plate 201, when the top plate 201 and the bottom plate 101 are closed, the bolt column 301 is limited and fixed, further increasing the limiting stability of the bolt column 301 for the sensor and the wire.
[0031] During the use process, the staff installs the rotating column 304 on the bolt column 301, then selects an appropriate number of installed bolt columns 301 according to the number and size of the fiber optic sensors to be installed, and screws multiple groups of bolt columns 301 into the first slot 106 to fix the two together, thereby limiting the fiber optic sensors, which is convenient for the staff to install sensors with different numbers and sizes, increasing the application range of the device and the comfort of use for the staff; then the staff connects multiple groups of optical fibers to the sensors in sequence, then arranges the installed fiber optic wires, and then screws multiple groups of bolt columns 301 into the first slot 106 again according to the wiring direction of the wires, thereby limiting and fixing the fiber optic wires, preventing the fiber optic wires from being not tightly pressed or poorly connected during the wiring installation process, and further increasing the safety and stability of fiber optic conduction.
[0032] Embodiment 2
[0033] Refer to Figure 1 - Figure 6, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is as follows: The limiting component 302 includes a snap ring 302a arranged on the bolt column 301, a limiting ring 302b arranged on the snap ring 302a, a second clamping post 302c arranged on the limiting ring 302b, and a spring post 302d arranged on the second clamping post 302c. The bolt column 301 is used to limit and fix the wire around its circumference, and the limiting ring 302b is used to limit and fix the wire at the top of the wire, so as to simultaneously limit and fix the circumference of the wire, increasing the stability of the wire arrangement, thereby improving the use safety and stability of the sensor inside the bottom plate 101.
[0034] Compared with Embodiment 1, further, a fourth slot 302e corresponding to the second clamping post 302c is provided at the bottom of the spring post 302d, and a third clamping post 302f corresponding to the second slot 204 is provided at the top of the spring post 302d. The fourth slot 302e is movably clamped with the second clamping post 302c, so as to select a spring post 302d with appropriate length and elastic size according to the number of wires limited by the limiting ring 302b and install it on the second clamping post 302c, so that the limiting ring 302b is closely attached to the wire below it, further increasing the stability and safety of wire fixation.
[0035] During the use process, after the staff limits the sensor and the wire through multiple bolt columns 301, at this time, according to the number of wire arrangement wires, the snap ring 302a is clamped outside the bolt column 301, and the snap ring 302a can move up and down outside the bolt column 301. Then the staff moves the snap ring 302a downward until the limiting ring 302b is closely attached to the optical fiber wire. Then the spring post 302d is inserted on the second clamping post 302c, and the second clamping post 302c is rotatably moved with the spring post 302d. Then the top plate 201 is aligned with the bottom plate 101 and closed together. When the top plate 201 and the bottom plate 101 are about to be closed, at this time, the third clamping post 302f at the top of the spring post 302d is controlled to be engaged with the second slot 204. Then the top plate 201 and the bottom plate 101 are closed together, and the fixing bolt 102 is passed through the connecting buckle 205 to tightly fix the two together, so as to limit the spring post 302d between the top plate 201 and the second clamping post 302c. Since the spring post 302d has a certain elasticity, one end of the fourth slot 302e will continuously press the second clamping post 302c, so that the limiting ring 302b at the bottom of the second clamping post 302c is closely attached to the optical fiber wire, so as to limit and fix the optical fiber wire, further increasing the wiring stability of the optical fiber wire and improving the signal transmission stability at the same time.
[0036] The remaining structures are the same as those in Embodiment 1.
[0037] Embodiment 3
[0038] Reference Figure 1 - Figure 6 This is the third embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: clamping grooves three 202 are provided inside both the bottom plate 101 and the top plate 201. A connection unit 400 is provided in the clamping groove three 202. The connection unit 400 includes a clamping plate two 402 provided in the top plate 201, a connecting plate 401 provided in the clamping plate two 402, a connection groove 403 provided on the connecting plate 401, a connection port 404 provided in the connection groove 403, and a connection cover plate 406 provided on the connection groove 403. Through multiple groups of connection grooves 403 on the connecting plate 401, it is convenient for the staff to install the interface according to the wiring direction of the wires inside the bottom plate 101, making the wiring inside the bottom plate 101 more stable. At the same time, it is convenient for the staff to connect other devices according to the interface, further increasing the comfort of use for the staff.
[0039] Among them, at least two layers of inclined grooves 405 are provided on the surface of the connection port 404. A diversion groove one 103 is provided on the bottom plate 101, and a clamping plate one 203 corresponding to the diversion groove one 103 is provided on the top plate 201. At least two groups of diversion grooves two 104 are provided on both sides of the bottom plate 101. When rainwater drops on the surface of the connecting plate 401 through the inclined grooves 405, the rainwater will flow along the inclined grooves 405, thereby preventing the rainwater from entering the connection port 404, and further increasing the use safety of the connection port 404.
[0040] During use, the staff selects an appropriate number of connection ports 404 according to the number of fiber optic sensors installed on the bottom plate 101. Then, according to the wiring direction of the fiber optic wires in the bottom plate 101, multiple groups of connection ports 404 are installed on one side of the connection plate 401. Next, the unused connection slots 403 are sealed with the connection cover plate 406. Then, the second clamping plate 402 is clamped in the bottom plate 101. Subsequently, the top plate 201 is aligned with the bottom plate 101, and the first clamping plate 203 at the bottom of the top plate 201 is engaged with the first diversion groove 103, and the third clamping slot 202 is engaged with the second clamping plate 402. Finally, the top plate 201 and the bottom plate 101 are fixed together by passing the first diversion groove 103 through the connection buckle 205. Since the first diversion groove 103 is connected to the second clamping plate 402, when there is rain, the rain first drips along the outer sides of the top plate 201 and the bottom plate 101, and some rainwater will enter the gap between the top plate 201 and the bottom plate 101. Then, the rainwater will first encounter the first diversion groove 103, and then the rainwater moves along the first diversion groove 103 to both sides thereof, so as to move to the position of the second clamping plate 402. Next, the rainwater will move downward along the gap between the second clamping plate 402 and the bottom plate 101, so as to move to the bottom of the second clamping plate 402. And the connection between the bottom of the second clamping plate 402 and the bottom plate 101 is provided with second diversion grooves 104 at equal intervals. Then, the rainwater will enter the second diversion grooves 104 and drip onto the ground, thereby preventing the external rainwater from entering the bottom plate 101 and damaging the electronic devices inside it, increasing the use safety and use stability of the electronic devices in the bottom plate 101, and at the same time increasing its service life and the waterproofness between the bottom plate 101 and the top plate 201.
[0041] The remaining structure is the same as that of Embodiment 2.
