DETAILED DESCRIPTION

[0030] 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.

[0031] The present invention provides Figure 1-7 The network data exchange device shown includes a network data exchange device body 101, a protection mechanism, and a positioning mechanism. A plurality of interfaces 102 are provided on the front of the network data exchange device body 101. External device connectors are inserted into the interfaces 102 to connect the external devices to the network data exchange device body 101.

[0032] In a preferred embodiment, the positioning mechanism is arranged inside the network data exchange device body 101, and the positioning mechanism includes multiple extrusion shafts 202. The inner wall of the interface 102 is provided with multiple movable holes 201, and the outer walls of the multiple extrusion shafts 202 are movably connected with the inner walls of the multiple movable holes 201. The network data exchange device body 101 is provided with an extrusion mechanism. When the connector of the external device is inserted into the interface 102, the multiple extrusion shafts 202 move in the corresponding movable holes 201 respectively until the extrusion shaft 202 squeezes the outer wall of the connector, thereby increasing the friction force on the connector in the interface 102, making the connector not easy to loosen in the interface 102, thereby improving the working stability of the network data exchange device body 101. The part of the extrusion shaft 202 close to the connector is made of rubber, so that when the extrusion shaft 202 is squeezed towards the connector, the rubber part will deform, so that the extrusion shaft 202 can stably resist the connector without causing damage to the connector.

[0033] Among them, the extrusion mechanism includes a U-shaped extrusion block 204, a sliding cavity 203 is opened inside the network data exchange device body 101, the U-shaped extrusion block 204 is slidably set inside the sliding cavity 203, and the outer wall of the U-shaped extrusion block 204 is opened with a slope 205. The extrusion shaft 202 is close to the end of the U-shaped extrusion block 204 and is provided with a hemispherical surface 206. The sliding cavity 203 is provided with a moving mechanism. The U-shaped extrusion block 204 moves inside the sliding cavity 203, so that the slope 205 squeezes the hemispherical surface 206 on the extrusion shaft 202, thereby causing the extruded extrusion shaft 202 to move toward the joint position until the extrusion shaft 202 is tightly against the joint.

[0034] Among them, the moving mechanism includes a screw rod 207, which is rotatably connected to the inner wall of the sliding cavity 203. A threaded hole 208 is provided on the front of the U-shaped extrusion block 204. The outer wall of the screw rod 207 is threadedly connected to the inner wall of the threaded hole 208. A reset mechanism is provided inside the movable hole 201. The screw rod 207 rotates in the threaded hole 208. Under the engagement of the outer wall of the screw rod 207 and the inner wall of the threaded hole 208, the rotation of the screw rod 207 can drive the U-shaped extrusion block 204 to move in the sliding cavity 203. At the same time, the sliding cavity 203 will limit the U-shaped extrusion block 204, so that the U-shaped extrusion block 204 can only move in the sliding cavity 203 without deflection, thereby improving the stability of the extrusion mechanism.

[0035] Among them, the reset mechanism includes a first fixing ring 210, and a first limiting cavity 209 is opened on the inner wall of the movable hole 201. The outer wall of the first fixing ring 210 is slidably connected to the inner wall of the first limiting cavity 209. The first fixing ring 210 is fixedly sleeved on the outer wall of the extrusion shaft 202. A first spring 211 is provided on one side of the first fixing ring 210. The first spring 211 is sleeved on the outer wall of the extrusion shaft 202. When the U-shaped extrusion block 204 moves in the opposite direction, the first spring 211 can be used to squeeze the first fixing ring 210 under the elastic action of the first spring 211, so that the extrusion shaft 202 moves in the opposite direction, so that the extrusion shaft 202 is no longer extruding the joint, and the joint can be pulled out from the interface 102.

[0036] Among them, a connection groove 301 is opened inside the network data exchange device body 101, and the interior of the connection groove 301 is connected to the interior of the interface 102. A rubber sleeve 302 is fixedly connected to the inner wall of the connection groove 301, and a pressurizing mechanism is provided between the connection groove 301 and the U-shaped extrusion block 204. When the external connector is inserted into the interface 102, the rubber sleeve 302 bulges and fits tightly against the outer wall of the connector, thereby sealing the connection between the connector and the interface 102 to prevent water from entering the interior of the interface 102, so that the network data exchange device body 101 can be stably connected to the external device, thereby improving the working stability of the network data exchange device body 101.

[0037] The pressurizing mechanism includes a piston block 305, a first connecting cavity 303 is provided inside the network data exchange device body 101, the interior of the first connecting cavity 303 is connected to the interior of the connecting groove 301, the interior of the first connecting cavity 303 is connected to the interior of the sliding cavity 203, the front of the U-shaped extrusion block 204 is fixedly connected to the first connecting block 304, the piston block 305 is fixedly connected to the front of the first connecting block 304, the outer wall of the piston block 305 is slidably connected to the inner wall of the first connecting cavity 303, and the interior of the first connecting cavity 303 is connected to the inner wall of the first connecting cavity 303. A pressure relief mechanism is provided in the part. When the extrusion mechanism is working, the U-shaped extrusion block 204 moves to drive the first connecting block 304 to move, and the movement of the first connecting block 304 drives the piston block 305 to move. The piston block 305 squeezes the space inside the first connecting chamber 303. Since the first connecting chamber 303 is connected to the connecting groove 301, the connecting groove 301 and the first connecting chamber 303 are in a positive pressure state, so that the rubber sleeve 302 can bulge in the interface 102 and fit closely to the outer wall of the joint, thereby ensuring the stability of the internal seal of the interface 102.

[0038] The pressure relief mechanism includes a connecting groove 306, which is provided at the bottom end of the inner wall of the first connecting cavity 303, and a first connecting ring 307 is fixedly connected to the bottom end of the inner wall of the connecting groove 306, and a second connecting ring 308 is fixedly connected to the inner wall of the connecting groove 306, and the second connecting ring 308 is arranged above the first connecting ring 307, and a blocking disk 309 is provided between the second connecting ring 308 and the first connecting ring 307, and a second spring 310 is provided between the top of the blocking disk 309 and the bottom end of the second connecting ring 308. When the plug 305 moves in the opposite direction, the first connecting chamber 303 and the connecting groove 301 will be in a negative pressure state. When the negative pressure inside the first connecting chamber 303 and the connecting groove 301 is relatively large, the blocking disk 309 rises to compress the second spring 310, so that the external air enters the first connecting chamber 303 and the connecting groove 301 through the connecting groove 306 to relieve the pressure, so that the negative pressure inside the first connecting chamber 303 and the connecting groove 301 is relatively small, ensuring that the next pressurizing mechanism can stably drive the rubber sleeve 302 to bulge.

[0039] Among them, a second connecting cavity 401 is provided at the bottom end of the inner wall of the sliding cavity 203, and the interior of the second connecting cavity 401 is connected to the interior of the communicating groove 306. The inner wall of the second connecting cavity 401 is slidably connected to a movable plate 403, and the bottom end of the U-shaped extrusion block 204 is fixedly connected to an L-shaped extrusion rod 402, and the L-shaped extrusion rod 402 is slidably arranged inside the second connecting cavity 401. A second limiting cavity 404 is provided on the inner wall of the second limiting cavity 404, and a second fixing ring 405 is slidably connected to the inner wall of the second fixing ring 405. The second fixing ring 405 is fixedly sleeved on the outer wall of the movable plate 403, and a third fixing ring 405 is provided on the front side of the second fixing ring 405. Spring 406, the third spring 406 is sleeved on the outer wall of the movable plate 403. When the extrusion mechanism is working, the U-shaped extrusion block 204 moves to drive the L-shaped extrusion rod 402 to move, and the L-shaped extrusion rod 402 squeezes the movable plate 403. The movement of the movable plate 403 drives the second fixing ring 405 to move, and the movement of the second fixing ring 405 compresses the third spring 406 until the movable plate 403 is inserted into the connecting groove 306. The movable plate 403 blocks the first connecting chamber 303 and the connecting groove 301 in a positive pressure state and prevents the pressure from being released through the connecting groove 306, so that the rubber sleeve 302 can stably play a sealing role.

[0040] Among them, the protection mechanism is set on the front of the interface 102, and the protection mechanism includes a movable baffle 501 symmetrically set on the front of the network data exchange device body 101. The front of the network data exchange device body 101 is symmetrically fixedly connected with a slide rail 502. The two movable baffles 501 are respectively slidably set between the two slide rails 502. The outer wall of the slide rail 502 is provided with a slide groove 503. The outer wall of the movable baffle 501 is fixedly connected with a slider 504. The outer wall of the slider 504 is slidably connected to the inner wall of the slide groove 503. The front of the slide rail 502 is provided with a groove shaped groove 505, the front of the slider 504 is fixedly connected to a second connecting block 506, the outer wall of the second connecting block 506 is slidably connected to the inner wall of the strip groove 505, one side of the strip groove 505 is fixedly connected to a connecting strip 507, the end of the connecting strip 507 is fixedly connected to a protrusion 508, a fourth spring 509 is provided on one side of the slider 504, a fixing rod 510 is fixedly connected to the inner wall of the slider 504, a limiting hole 511 is provided on one side of the slider 504, the outer wall of the fixing rod 510 is slidably connected to the inner wall of the limiting hole 511, and the fourth spring 509 is provided on one side of the slider 504. 9 is sleeved on the outer wall of the fixed rod 510. When the interface 102 is not in use, under the elastic action of the two fourth springs 509, the fourth spring 509 squeezes the slider 504, so that the two movable baffles 501 have a tendency to move relative to each other, so that the two movable baffles 501 can block the interface 102, preventing the interface 102 from directly contacting the outside world, and playing a dust-proof role for the unused interface 102. When the connector needs to be inserted into the interface 102, two fingers respectively squeeze the two protrusions 508 relative to each other at the same time, and the protrusions The movement of 508 drives the connecting strip 507 to move, the movement of the connecting strip 507 drives the second connecting block 506 to move, the movement of the second connecting block 506 drives the slider 504 to move, and the movement of the slider 504 drives the movable baffle 501 to move until the interface 102 is exposed and the connector is inserted into the interface 102. At this time, release the two protrusions 508, and the two movable baffles 501 can be pressed against the two sides of the connector under the elastic action of the fourth spring 509, further increasing the friction force on the connector, so that the connector can be stably inserted into the interface 102.
