[0013] A method for using a retractable meter box door stopper fixing tool comprises the following steps:

[0014] S1: When using this device, first pull out the hidden part inside the multi-stage telescopic rod to increase the length of the multi-stage telescopic rod to adapt to the height of the metering box. Then, use the multi-stage telescopic rod to control the overall movement of the right-angle plate so that the suction cup on the left side of the right-angle plate fits on the door of the metering box. Then start the dual-axis motor to fix the device on the metering box at a high place.

[0015] S2: When the right-angle plate moves toward the metering box, the air inside the air storage box 2 will be pushed into the air guide hose 1, thereby expanding the annular air bag, causing the suction cup to fold and shrink, changing from a trumpet shape to a cylindrical shape. After the annular air bag is fully expanded, the air continues to flow into the air storage box 1, and the air will be ejected from the suction cup to blow away the dust in some areas of the metering door;

[0016] S3: When the push rod drives the pressure plate 2 to move, the fitting block will be pulled to the left, and then the dust shield plate 1 will be pulled to move together through the sliding rod 2, so that the dust shield plate no longer blocks the suction cup. As the air guide hose 3 continues to suck out air, the sliding rod 2 will be pulled to the right.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention first pulls out the hidden part inside the multi-stage telescopic rod to increase the length of the multi-stage telescopic rod, so as to adapt to the height of the metering box. A plurality of springs 1, sliding circular plates and limit balls are respectively arranged inside the multi-stage telescopic rod, which can make each stage of the multi-stage telescopic rod stuck when it is extended to the final position to prevent the multi-stage telescopic rod from being recovered. Subsequently, the multi-stage telescopic rod is used to control the overall movement of the right-angle plate so that the suction cup on the left side of the right-angle plate is attached to the box door of the metering box. Then, the dual-axis motor is started to drive the two moving plates to move in the direction away from each other. During the movement, the moving plate will drive the two pressing plates 1 to move in the direction away from each other. During the movement of the two pressing plates 1, the air between the two pressing plates 1 will be stretched to generate negative pressure. Therefore, the shielding plate will compress the spring 2 and move to the right. When the shielding plate and the straight After the angle plate is separated, as the two pressure plates continue to move, negative pressure will also be generated in the air guide cavity, which will cause negative pressure to be generated in the space generated after the suction cup and the metering box are attached, and then the right-angle plate can be adsorbed on the metering box door as a whole through the negative pressure. During the movement, the movable plate will also drive the fixed slide plate to move to the left through the pull rod, and the fixed slide plate will drive the door suction fixing machine to move to the left until the left mounting port of the door suction fixing machine contacts the metering box door. At this time, the door suction fixing machine can be started to install the door suction. This design enables the device to complete complex installation tasks in a relatively small space, which is convenient for carrying and storage. At the same time, the device can also be adsorbed and fixed on a high metering box to automatically install the door suction, reducing the need for manual operation. This not only improves efficiency, but also reduces installation inaccuracies caused by human factors.

[0019] 2. In the process of the right-angle plate moving toward the metering box of the present invention, the push rod will first contact the metering box door, and as the right-angle plate continues to move, the push rod will move to the right relative to the right-angle plate, and the push rod will drive the pressure plate 2 to move together and squeeze the air inside the air storage box 2 during the movement, and the squeezed air in the air storage box 2 will be pushed into the air guide hose 1, and the air guide hose 1 will pass the air into the air storage box 1. The air passed into the air storage box 1 will first enter the air guide cavity 2 due to the obstruction of the baffle plate, and the air guide cavity 2 will pass the air into a number of annular air bags and expand them, and the annular air bags will squeeze the suction cup during the expansion process, causing it to fold and shrink, and change from a trumpet shape to a cylindrical shape. This design can prevent the dust blown off from the upper layer from falling on the left suction surface of the suction cup during the subsequent cleaning component operation, thereby preventing the dust falling on the suction cup from affecting the sealing between the suction cup and the metering box, thereby reducing the adsorption force.

[0020] 3. After the annular airbag of the present invention is fully inflated, as the air guide hose 1 continues to pass air into the air storage box 1, the air will push the baffle to the left, so that the air passed into the air storage box 1 can enter the air guide cavity 1, and the air guide cavity 1 will transport the air to each suction cup and spray it to the left through the adsorption hole opened on the right side of the suction cup, and the sprayed air flow will hit the metering box, and then the dust on the contact part between the suction cup and the metering box can be cleaned and blown away, and in the process of the above-mentioned two pressure plates 1 moving away from each other, it will squeeze the air inside the air storage box 1 and push it into the air guide hose 2, and the air guide hose 2 will pass the air into the jet head and spray it through the nozzle of the jet head, and then the dust at the position where the door suction is to be installed can be blown away. This design can ensure the cleanliness of the contact surface between the suction cup and the metering door by blowing away the dust in a partial area of ​​the metering door, thereby improving the adsorption effect and the installation quality, and blowing away the dust can ensure that the installation part is flat and clean, thereby improving the installation accuracy and stability of the door suction.

[0021] 4. In the process of the push rod driving the pressing plate 2 to move, the pressing plate 2 will suck the air in the fixed shell into the air storage box 2 through the air guide hose 3. However, due to the obstruction of the spring 4, the suction force will not pull the two sliding rods 1 first, but will first suck out the air inside the dust shield through the sliding rod 1 and the sliding rod 2, thereby generating negative pressure inside the dust shield, and then the fitting block is pulled to the left by the negative pressure, so that the fitting block is separated from the suction cup. At this time, as the air guide hose 3 continues to suck out the air in the fixed shell, negative pressure will be generated in the fixed shell, thereby Pull the two sliding rods 1 closer to each other and compress the spring 4. During the movement of the sliding rod 1, the sliding rod 1 will pull the dust baffle 1 through the sliding rod 2 to move together, so that the dust baffle no longer blocks the suction cup. As the air guide hose 3 continues to suck out air, the sliding rod 2 will be pulled to the right and compress the spring 5, so that the dust baffle will not hinder the suction cup from contacting the metering box. This design can prevent the suction cup from being exposed to the air for a long time, adhering to dust and affecting the adsorption force of the suction cup through the dust baffle and the bonding block when the device is not working.

[0042] The spring 102 is fixedly connected to the inner wall of the multi-stage telescopic rod 101 at one end away from the sliding circular plate 103, and the sliding circular plate 103 is rotatably connected to the limit ball 104 on the side away from the spring 102. The outer surface of the limit ball 104 is rotatably connected to the inner wall of the multi-stage telescopic rod 101. The top of the multi-stage telescopic rod 101 is rotatably connected to a rotating rod 105, and the outer surface of the rotating rod 105 is rotatably connected to a right-angle plate 106. The right side of the right-angle plate 106 is fixedly connected to a dual-axis motor 107.

First, the inner surface of the multi-stage telescopic rod 101 is hidden. The hidden part is pulled out to increase the length of the multi-stage telescopic rod 101, so as to adapt to the height of the metering box. A plurality of springs 102, sliding circular plates 103 and limit balls 104 are respectively arranged inside the multi-stage telescopic rod 101, which can make each stage of the multi-stage telescopic rod 101 stuck when it is extended to the final position to prevent the multi-stage telescopic rod 101 from being recovered. Then, the multi-stage telescopic rod 101 is used to control the overall movement of the right-angle plate 106, so that the suction cup 118 on the left side of the right-angle plate 106 is attached to the box door of the metering box, and then the dual-axis motor 107 is started to drive the two movable plates 108 to move in a direction away from each other.

At the same time, the device can also be adsorbed and fixed on a metering box at a high place to automatically install the door suction, reducing the need for manual operation. This not only improves efficiency, but also reduces installation inaccuracies caused by human factors.

[0045] For example 2, please refer to Fig. 9 - Fig.13The present invention is a retractable metering box door suction fixing tool. On the basis of Example 1, the outer surface of the push rod 201 is slidably connected to the inner wall of the right-angle plate 106, the right side of the spring three 204 is fixedly connected to the gas storage box two 205, the left side of the gas storage box two 205 is fixedly connected to the right side of the right-angle plate 106, the outer surface of the pressure plate two 202 is slidably connected to the inner wall of the gas storage box two 205, the right side of the gas storage box two 205 is fixedly connected to the gas guide hose one 206, the top of the gas storage box one 109 is fixedly connected to one end of the gas guide hose one 206, the right-angle plate 106 is provided with a gas guide cavity two 207, the inner wall of the right-angle plate 106 is fixedly connected to an annular air bag 208, in the process of the right-angle plate 106 moving toward the metering box, the push rod 201 will first contact the metering box door, as the right-angle plate 106 continues to move, the push rod 201 will move to the right relative to the right-angle plate 106, and the push rod 201 During the movement, the pressure plate 202 will be driven to move together and squeeze the air inside the air storage box 205. The squeezed air in the air storage box 205 will be pushed into the air guide hose 206. The air guide hose 206 will pass the air into the air storage box 109. The air passed into the air storage box 109 will first enter the air guide cavity 207 due to the obstruction of the baffle plate 116. The air guide cavity 207 will pass the air into several annular air bags 208 and expand them. The annular air bags 208 will squeeze the suction cup 118 during the expansion process, causing it to fold and shrink, changing from a trumpet shape to a cylindrical shape. This design ensures that during the subsequent operation of the cleaning component 2, the dust blown off from the upper layer will not fall on the left suction surface of the suction cup 118, thereby preventing the dust falling on the suction cup 118 from affecting the sealing between the suction cup 118 and the metering box, thereby reducing the adsorption force.

[0046] The front and back of the air storage box 109 are respectively fixedly connected with an air guide hose 209, and the air guide hose 209 is fixedly connected with an injection head 210 at one end away from the air storage box 109. The right side of the injection head 210 is fixedly connected to the left side of the door stopper fixing machine 113. After the annular airbag 208 is fully expanded, as the air guide hose 206 continues to pass air into the air storage box 109, the air will push the baffle plate 116 to the left, so that the air passed into the air storage box 109 can enter the air guide cavity 117, and the air guide cavity 117 will transport the air to each suction cup 118, and spray it to the left through the adsorption hole opened on the right side of the suction cup 118, and the sprayed airflow will hit the metering box The dust on the contact part of the suction cup 118 with the metering box can be cleaned and blown away, and in the process of the two pressure plates 110 moving away from each other, the air inside the air storage box 109 will be squeezed and pushed into the air guide hose 209, and the air guide hose 209 will pass the air into the nozzle 210 and spray it out through the nozzle of the nozzle 210, thereby blowing away the dust at the position where the door suction is to be installed. This design can ensure the cleanliness of the contact surface between the suction cup 118 and the metering door by blowing away the dust in part of the metering door, thereby improving the adsorption effect and installation quality, and blowing away the dust can ensure that the installation part is flat and clean, thereby improving the installation accuracy and stability of the door suction.

[0047] The air guide hose 301 is fixedly connected to the outer wall of the right angle plate 106 at one end away from the fixed shell 302, the left side of the fixed shell 302 is fixedly connected to the right side of the right angle plate 106, the two sliding rods 303 are fixedly connected to the spring 4 3021 on the side close to each other, the outer surface of the sliding rod 1 303 is slidably connected to the sliding rod 2 304, the outer surface of the sliding rod 2 304 is slidably connected to the inner wall of the right angle plate 106, the left side of the sliding rod 1 303 is fixedly connected to the spring 5 3041, the left side of the sliding rod 2 304 is fixedly connected to the dust blocking The left side of the spring five 3041 is fixedly connected to the right side of the ash baffle plate 305, and the inner wall of the ash baffle plate 305 is slidably connected with a fitting block 306, and the right side of the fitting block 306 contacts the left side of the suction cup 118. When the push rod 201 drives the pressure plate two 202 to move, the pressure plate two 202 will suck the air in the fixed shell 302 into the air storage box two 205 through the air guide hose three 301. However, due to the obstruction of the spring four 3021, the suction force will not pull the two sliding rods one 303 first, but will first pass through the sliding rod one 303 and the sliding The movable rod 2 304 sucks out the air inside the dust shield 305, thereby generating negative pressure inside the dust shield 305, and then the negative pressure pulls the fitting block 306 to move to the left, so that the fitting block 306 is separated from the suction cup 118. At this time, as the air guide hose 301 continues to suck out the air in the fixed shell 302, negative pressure is generated in the fixed shell 302, thereby pulling the two sliding rods 1 303 closer to each other and compressing the spring 4 3021. During the movement, the sliding rod 1 303 pulls the dust shield through the sliding rod 2 304 The plate 305 moves together, so that the dust shield plate 305 no longer blocks the suction cup 118. As the air guide hose three 301 continues to suck out air, the sliding rod two 304 will be pulled to the right and compress the spring five 3041, so that the dust shield plate 305 will not hinder the suction cup 118 from contacting with the metering box. This design can prevent the suction cup 118 from being exposed to the air for a long time, adhering to dust and affecting the adsorption force of the suction cup 118 through the dust shield plate 305 and the fitting block 306 when the device is not working.

[0048] The method of using the meter box door stopper fixing tool includes the following steps:

[0049] S1: When using the device, first pull out the hidden part inside the multi-stage telescopic rod 101 to increase the length of the multi-stage telescopic rod 101, so as to adapt to the height of the metering box. Then, the multi-stage telescopic rod 101 is used to control the overall movement of the right-angle plate 106, so that the suction cup 118 on the left side of the right-angle plate 106 is attached to the door of the metering box. Then, the dual-axis motor 107 is started to fix the device on the metering box at a high position by adsorption.

[0050] S2: When the right-angle plate 106 moves toward the metering box, the air inside the air storage box 205 will be pushed into the air guide hose 1 206, thereby expanding the annular air bag 208, causing the suction cup 118 to fold and shrink, changing from a trumpet shape to a cylindrical shape. After the annular air bag 208 is fully expanded, the air continues to flow into the air storage box 1 109, and the air will be ejected from the suction cup 118 to blow away the dust in the area of ​​the metering door;

[0051] S3: When the push rod 201 drives the pressure plate 202 to move, the fitting block 306 will be pulled to the left, and then the dust shield 305 will be pulled to move together through the sliding rod 204, so that the dust shield 305 no longer blocks the suction cup 118. As the air guide hose 301 continues to suck out air, the sliding rod 2 304 will be pulled to the right.

[0052] A specific application of this embodiment is:

[0053] When using the device, first pull out the hidden part inside the multi-stage telescopic rod 101 to increase the length of the multi-stage telescopic rod 101, so as to adapt to the height of the metering box. The multi-stage telescopic rod 101 is respectively provided with a plurality of springs 102, sliding circular plates 103 and limit balls 104. This can make each stage of the multi-stage telescopic rod 101 stuck when it is extended to the final position, so as to prevent the multi-stage telescopic rod 101 from being recovered. Then, the multi-stage telescopic rod 101 is used to control the overall movement of the right-angle plate 106, so that the suction cup 118 on the left side of the right-angle plate 106 is attached to the door of the metering box, and then the dual-axis motor 107 is started to drive the two moving plates 108 to move in a direction away from each other. During the movement, the moving plate 108 will drive the two pressing plates 110 to move in a direction away from each other. During the movement of the two pressing plates 110, the air between the two pressing plates 110 will be stretched to generate negative pressure, so the shielding plate 116 will compress the spring 115 and When the shielding plate 116 is separated from the right-angle plate 106, as the two pressing plates 110 continue to move, negative pressure is also generated in the air guide cavity 117, which can also generate negative pressure in the space generated after the suction cup 118 and the metering box are attached, and then the right-angle plate 106 can be adsorbed on the metering box door as a whole through the negative pressure. During the movement, the movable plate 108 can also drive the fixed slide plate 112 to move to the left through the pulling rod 111, and the fixed slide plate 112 can drive the door suction fixing machine 113 to move to the left until the left installation port of the door suction fixing machine 113 contacts the metering box door. At this time, the door suction fixing machine 113 can be started to install the door suction. This design enables the device to complete complex installation tasks in a relatively small space, which is convenient for carrying and storage. At the same time, the device can also be adsorbed and fixed on the metering box at a high place, and the door suction installation is automatically performed, which reduces the need for manual operation, not only improves efficiency, but also reduces installation inaccuracies caused by human factors.

[0054] In the process of the right-angle plate 106 moving toward the metering box, the push rod 201 will first contact the metering box door. As the right-angle plate 106 continues to move, the push rod 201 will move to the right relative to the right-angle plate 106. In the process of moving, the push rod 201 will drive the pressure plate 202 to move together and squeeze the air inside the gas storage box 205. The squeezed air in the gas storage box 205 will be pushed into the air guide hose 1 206. The air guide hose 1 206 will pass the air into the gas storage box 1 109. The air in the gas storage box 109 is The blocking of the shielding plate 116 will first enter the second air guide cavity 207, and the second air guide cavity 207 will pass air into a plurality of annular air bags 208 and expand them. The annular air bags 208 will squeeze the suction cup 118 during the expansion process, causing it to fold and shrink, changing from a trumpet shape to a cylindrical shape. This design can prevent the dust blown off from the upper layer from falling on the left suction surface of the suction cup 118 during the subsequent operation of the cleaning component 2, preventing the dust falling on the suction cup 118 from affecting the sealing between the suction cup 118 and the metering box, resulting in reduced adsorption force;

[0055] After the annular airbag 208 is fully inflated, as the air guide hose 206 continues to pass air into the air storage box 109, the air will push the shielding plate 116 to the left, so that the air passed into the air storage box 109 can enter the air guide cavity 117, and the air guide cavity 117 will transport the air to each suction cup 118 and spray it to the left through the adsorption hole on the right side of the suction cup 118. The sprayed airflow will hit the metering box, thereby cleaning and blowing away the dust on the contact part between the suction cup 118 and the metering box, and the above two pressure plates 110 In the process of moving away from each other, the air in the air storage box 109 will be squeezed and pushed into the air guide hose 209, and the air guide hose 209 will pass the air into the nozzle 210 and spray it out through the nozzle of the nozzle 210, thereby blowing away the dust at the location where the door suction is to be installed. This design can ensure the cleanliness of the contact surface between the suction cup 118 and the metering door by blowing away the dust in a part of the metering door, thereby improving the adsorption effect and installation quality, and blowing away the dust can ensure that the installation location is flat and clean, thereby improving the installation accuracy and stability of the door suction;

[0056] In the process that the push rod 201 drives the pressure plate 202 to move, the pressure plate 202 will suck the air in the fixed shell 302 into the air storage box 205 through the air guide hose 301. Due to the obstruction of the spring 4 3021, the suction force will not pull the two sliding rods 1 303 first, but will first suck out the air inside the dust shield 305 through the sliding rod 1 303 and the sliding rod 2 304, thereby generating negative pressure inside the dust shield 305, and then the negative pressure will pull the fitting block 306 to move to the left, so that the fitting block 306 is separated from the suction cup 118. At this time, as the air guide hose 301 continues to suck out the air in the fixed shell 302, negative pressure will be generated in the fixed shell 302, thereby Pull the two sliding rods 1 303 closer to each other and compress the spring 4 3021. During the movement of the sliding rod 1 303, the sliding rod 2 304 will pull the dust baffle 305 to move together, so that the dust baffle 305 no longer blocks the suction cup 118. As the air guide hose 3 301 continues to suck out air, the sliding rod 2 304 will be pulled to the right and compress the spring 5 3041, so that the dust baffle 305 will not hinder the suction cup 118 from contacting the metering box. This design can prevent the suction cup 118 from being exposed to the air for a long time, adhering to dust and affecting the adsorption force of the suction cup 118 through the dust baffle 305 and the fitting block 306 when the device is not working.
