The two L-shaped rods are respectively adapted to the two guide rail plates.

[0013] In some embodiments, the top of both guide rails is provided with notches and slots, and the two L-shaped rods are respectively adapted to the two notches and slots.

[0014] In some embodiments, the lifting mechanism includes a lifting unit and a pressing and fixing unit.

The bottom of each of the two electric telescopic rods is fixedly connected to a mounting column. The bottom of each of the two mounting columns is provided with a movable groove. A movable column is slidably connected in each of the two movable grooves. A card seat is fixedly connected to the bottom of each of the two movable columns.

[0015] In some embodiments, each of the two movable columns is fitted with a telescopic spring, and the two ends of the telescopic spring are fixedly connected to the card seat and the mounting column, respectively.

[0016] In some embodiments, the compression fixing unit includes movable slots respectively opened on both sides of the two card seats, movable plates slidably connected in each of the four movable slots, hooks fixedly connected to the bottom of one end of each of the four movable plates, two card slots opened on the top of each of the two fixing frames, the four hooks respectively located in the four card slots, inclined blocks fixedly connected to the top of each of the four movable plates, and two compression rods fixedly connected to the outer cylindrical wall of each of the two mounting columns, the two compression rods respectively being adapted to the two inclined blocks.

[0017] In some embodiments, each of the four movable slots is provided with a compression spring, and the two ends of the compression spring are fixedly connected to the movable plate and the card seat, respectively.

[0019] In some embodiments, the inner walls of both card holders are fixedly connected with second arc-shaped ribs, and the two second arc-shaped ribs are respectively located in the two rib grooves.

[0020] This invention provides a replaceable air-expansion connector with the following improvements and advantages compared to the prior art:

[0021] Firstly, this invention, through the setting of a material changing mechanism and a lifting mechanism, firstly drives the card seat to rise, so that the card seat rises to a suitable position. Then, the telescopic hydraulic cylinder first drives the sliding plate to lift the connector body to be replaced and the connector body to be replaced. Then, it pushes the sliding plate to move, so that the connector body to be replaced moves to the bottom of the card seat. At this time, the return spring drives the sliding plate to return to its original position, so that the connector body to be replaced enters the mounting slot. This realizes the automatic replacement of air expansion connectors without the need for manual operation, improves the automation level of air expansion connector replacement, and thus improves the effect of air expansion connector replacement.

[0022] Secondly, this invention uses a lifting mechanism where an electric telescopic rod moves the mounting column upwards. Under the action of a telescopic spring, the mounting column first moves the pressing rod away from the inclined block, and the pressing spring moves the hook away from the slot. Then, it moves the card holder upwards, so that the card holder is away from the fixing frame and the fixing ring. The electric telescopic rod moves the mounting column downwards, and the card holder contacts the fixing frame first. Then, under the action of the pressing rod and the inclined block, the hook enters the slot, thereby fixing the card holder and improving the fixing effect of the card holder on the connector body.

[0023] Thirdly, this invention utilizes a material-changing mechanism. A telescopic hydraulic cylinder drives two fixed blocks to move, causing the fixed column to first drive the L-shaped rod to press the guide rail plate, sliding rod, fixed track, and sliding plate upwards. The upward movement of the sliding plate lifts the connector body to be replaced and the connector body to be replaced. Then, the fixed column presses the square frame, causing the sliding plate to move on the fixed track until the sliding plate moves the connector body to be replaced to the bottom of the card slot. At this point, the L-shaped rod moves to the notch position, and the reset spring, which is not subject to external force, drives the sliding rod to move and reset. The sliding rod drives the fixed track and sliding plate to reset, and the reset sliding plate places the connector body to be replaced into the mounting slot in the middle, thus realizing the replacement of the connector body.

[0035] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides an improved replaceable air-expanding connector. The technical solution of this invention is as follows:

[0037] like Figures 1-8As shown, a replaceable air-expanding connector includes two fixed frames 1. Each fixed frame 1 has three sets of mounting slots 109 on its top. A fixing ring 401 is placed in the middle mounting slot 109. The inner walls of the two fixing rings 401 are rotatably connected to the connector body 4. The outer cylindrical walls of the two fixing rings 401 each have protruding rib grooves 402. The connector also includes a material changing mechanism, a lifting mechanism, and two L-shaped frames 3. To improve the stability of the L-shaped frames 3, they are fixed to the fixed frames 1 by welding. The two L-shaped frames 3 are respectively fixedly connected to the tops of the two fixed frames 1. The material changing mechanism is located on the fixed frames 1. The lifting mechanism is located on the L-shaped frames 3. The material changing mechanism includes a material picking unit and a driving unit. The material picking unit includes two fixing rods 101 respectively fixedly connected to the two fixed frames 1 on their adjacent sides. The fixing rods 101 are fixed to the fixed frames 1 by welding, improving the stability of the fixing rods 101. Each of the four fixing rods 101 has a sliding groove at its top, and a sliding rod 1 is slidably connected in each of the four sliding grooves. 02. A fixed rail 103 is fixedly connected to the top of each pair of sliding rods 102. A sliding plate 104 is slidably connected to each of the two fixed rails 103. A return spring 106 is provided in each of the four sliding grooves. The two ends of the return spring 106 are fixedly connected to the fixed rod 101 and the sliding rod 102 respectively. A guide rail plate 107 is fixedly connected to each pair of sliding rods 102. A square frame 204 is fixedly connected to the side of each of the two sliding plates 104 that are close to each other. Two grooves 105 are opened on one side of each of the two sliding plates 104. With the above structure, through the setting of the material changing mechanism, the drive unit first drives the sliding rod 102, the fixed rail 103 and the sliding plate 104 to move upward, so that the sliding plate 104 lifts the connector body 4 to be replaced and the connector body 4 to be replaced. Then, the sliding plate 104 is pushed to move, so that the connector body 4 to be replaced moves to the position of the middle set of mounting grooves 109, until the connector body 4 to be replaced enters the middle set of mounting grooves 109, realizing the automatic replacement of the air expansion connector.

[0038] like Figure 3As shown, in one embodiment, to facilitate later maintenance of the telescopic hydraulic cylinder 2, the telescopic hydraulic cylinder 2 is fixed to the fixed frame 1 by screw connection. The drive unit includes telescopic hydraulic cylinders 2 respectively fixedly connected to the two fixed frames 1 on their respective sides close to each other. The output ends of the two telescopic hydraulic cylinders 2 are fixedly connected to fixed blocks 201. One side of each of the two fixed blocks 201 is fixedly connected to a fixed post 203. One end of each of the two fixed posts 203 extends into the two square frames 204. The bottom of each of the two fixed blocks 201 is fixedly connected to an L-shaped rod 202. The two L-shaped rods 202 are respectively adapted to the two guide rail plates 107. With the above structure, through the setting of the drive unit, the telescopic hydraulic cylinder 2 drives the fixed block 201 to move, so that the fixed block 201 lifts the sliding plate 104 through the L-shaped rod 202 and the guide rail plate 107, and then pushes the sliding plate 104 to move through the fixed post 203 and the square frame 204, thereby realizing the movement of the sliding plate 104.

[0039] like Figure 2 As shown, in one embodiment, the top of each of the two guide rail plates 107 is provided with a notch 108, and the two L-shaped rods 202 are respectively adapted to the two notches 108. With the above structure, by setting the notch 108, when the L-shaped rod 202 moves to the position of the notch 108, the reset spring 106 drives the sliding plate 104 to move downward, so that the connector body 4 to be replaced enters the middle set of mounting slots 109, thereby realizing the replacement of the connector body 4.

[0040] like Figure 5As shown, in one embodiment, to facilitate later maintenance of the electric telescopic rod 301, the electric telescopic rod 301 is fixed to the L-shaped frame 3 by screw connection. The lifting mechanism includes a lifting unit and a pressing and fixing unit. The lifting unit includes electric telescopic rods 301 respectively fixedly connected to the top of one end of the two L-shaped frames 3. The bottom end of each of the two electric telescopic rods 301 is fixedly connected to a mounting column 302. The bottom of each of the two mounting columns 302 is provided with a movable groove. A movable column 303 is slidably connected in each of the two movable grooves. The bottom end of each of the two movable columns 303 is fixedly connected to a card seat 305. The two card seats 305 are respectively in contact with the top of the two fixed frames 1. The two card seats 305 are respectively connected to the middle of the frame 301. The two mounting slots 109 are compatible, and each of the two movable columns 303 is fitted with a telescopic spring 304. The two ends of the telescopic spring 304 are fixedly connected to the card holder 305 and the mounting column 302, respectively. With the above structure, through the setting of the lifting mechanism, the electric telescopic rod 301 drives the mounting column 302 to rise and fall. The rising and falling of the mounting column 302 drives the telescopic spring 304 and the card holder 305 to rise and fall, so that the card holder 305 can press the connector body 4, thereby fixing the connector body 4. The setting of the telescopic spring 304 can play a buffering role. When the card holder 305 presses the connector body 4, the electric telescopic rod 301 can also drive the mounting column 302 to move downward.

[0041] like Figure 6 As shown, in one embodiment, the compression fixing unit includes movable slots respectively opened on both sides of the two card seats 305. Movable plates 307 are slidably connected in each of the four movable slots. Hooks 311 are fixedly connected to the bottom of one end of each of the four movable plates 307. Two card slots 312 are opened on the top of each of the two fixing frames 1. The four hooks 311 are respectively located in the four card slots 312. Inclined blocks 309 are fixedly connected to the top of each of the four movable plates 307. Two compression rods 310 are fixedly connected to the outer cylindrical walls of the two mounting columns 302. The two compression rods 310 are respectively connected to the two... Each of the four movable slots is equipped with a compression spring 308, and the two ends of the compression spring 308 are fixedly connected to the movable plate 307 and the card seat 305, respectively. With the above structure, when the card seat 305 presses down on the connector body 4, the electric telescopic rod 301 drives the mounting column 302 and the compression rod 310 to move downward. The compression rod 310 compresses the two inclined blocks 309, causing the movable plate 307 to move closer to each other. The movement of the movable plate 307 causes the hook 311 to lock the card slot 312, thereby fixing the card seat 305.

[0042] like Figure 7As shown, in one embodiment, the inner walls of the three sets of mounting grooves 109 are all fixedly connected with first arc-shaped ribs 110, one set of first arc-shaped ribs 110 is located in two rib grooves 402 respectively, and the inner walls of the two card holders 305 are all fixedly connected with second arc-shaped ribs 306, the two second arc-shaped ribs 306 are located in two rib grooves 402 respectively; by means of the above structure, the setting of the first arc-shaped ribs 110 and the second arc-shaped ribs 306 realize the function of limiting the connector body 4.

[0043] Working principle: When replacing the connector body 4, place the connector body 4 to be replaced into a set of mounting slots 109 near the L-shaped frame 3. Simultaneously activate the two electric telescopic rods 301, causing the electric telescopic rods 301 to drive the mounting post 302 upward. Since the telescopic spring 304 is in a compressed state, the card holder 305 will not move upward under the squeezing force of the telescopic spring 304. This causes the mounting post 302 to move, driving the two squeezing rods 310 upward, gradually moving the two squeezing rods 310 away from the two inclined blocks 309. Since the two squeezing springs 308 are in a compressed state, the squeezing springs 308 push the movable plate 307 outward. The movement of the movable plate 307 drives the two hooks 311, causing the two hooks 311 to move away from the two inclined blocks 309. As the electric telescopic rod 301 continues to move upward from the slot 312, the telescopic spring 304 slowly returns to its original position. When the telescopic spring 304 is fully returned to its original position, it drives the card holder 305 to move upward, moving the card holder 305 away from the fixed frame 1 and the fixed ring 401. When the card holder 305 is raised to a suitable position, the two telescopic hydraulic cylinders 2 are simultaneously activated, driving the two fixed blocks 201 to move towards the L-shaped frame 3. The movement of the fixed blocks 201 drives the fixed column 203 and the L-shaped rod 202 to move. As the fixed column 203 moves to the square frame 204, the L-shaped rod 202 moves past the inclined edge of the guide rail plate 107, causing the L-shaped rod 202 to press against the guide rail plate 107 and move upward. The movement of the guide rail plate 107 drives the two sliding rods 102. The movement of the two sliding rods 102 causes the return spring 106 to move and undergo elastic deformation. The movement of the sliding rods 102 causes the fixed track 103 and the sliding plate 104 to move upward. The upward movement of the sliding plate 104 lifts the connector body 4 to be replaced and the connector body 4 to be replaced. As the telescopic hydraulic cylinder 2 drives the fixed block 201 to move continuously, the fixed column 203 presses the square frame 204 to move. The movement of the square frame 204 causes the sliding plate 104 to move on the fixed track 103 until the sliding plate 104 moves the connector body 4 to be replaced to below the card seat 305. At this time, the L-shaped rod 202 moves to the position of the notch 108, and the return spring 106, which is not subject to external force, drives the sliding rod 102 to move and reset. The sliding rod 102 drives the fixed track 103 and the sliding plate 104 to reset. The reset of the sliding plate 104 places the connector body 4 into the central mounting slot 109. Simultaneously, two telescopic hydraulic cylinders 2 are activated, driving the two fixed blocks 201 to reset the two sliding plates 104. Then, two electric telescopic rods 301 are activated, moving the mounting column 302 downwards, causing the two retaining seats 305 to cover and fix the connector body 4. Continuing to move downwards, the two pressing rods 310 press the two inclined blocks 309, causing the two movable plates 307 to move closer together. The movement of the two movable plates 307 causes the two hooks 311 to engage the retaining slots 312. The replaced connector body 4 can then be removed, thus achieving automatic replacement of the air-expanding connector.No manual intervention is required, increasing the automation level of air-expanding connector replacement and thus improving the efficiency of the replacement process.
