Description

Technical Field

[0001] The present invention relates to the technical field of box door detection equipment, and in particular to a metering box door opening and closing detection device and a detection method thereof. Background Art

[0002] The meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electric energy, including electric energy meters, voltage and current transformers for measurement and their secondary circuits, electric energy metering panels, cabinets, boxes, etc. The meter box door needs to be tested for performance before leaving the factory. One of the test items is to test the opening and closing of the door. However, the existing opening and closing detection devices for meter box doors can only perform fixed-angle opening and closing tests when in use. Current meter boxes are mostly shaped by stamping metal sheets, and in order to increase the pressure-bearing capacity of the meter box and the meter box door, curling designs are often performed at the edges.

[0003] However, after the meter box door is stamped and curled, the rebound force of the metal will force a slight rebound at the curling position, causing the edge of the door to expand. The door will be too large when merged, making it difficult to fit completely with the inner wall of the meter box, affecting the opening and closing effect of the meter box. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a metering box door opening and closing detection device, comprising a pneumatic box, a piston plate is slidably connected to the inner wall of the pneumatic box, four pneumatic telescopic rods are through-connected to the side wall of the pneumatic box, four telescopic rods are fixedly connected to the side wall of the pneumatic box, a push rod is fixedly connected to the top of the piston plate, an electric telescopic rod is fixedly connected to the top of the push rod, a cleaning component is fixedly connected to the top of the pneumatic telescopic rod, and a positive angle detection component is fixedly connected to the side wall of the push rod;

[0005] The internal angle detection mechanism includes an L-shaped track fixedly connected to the end of the telescopic rod away from the air pressure box, the end of the L-shaped track away from the telescopic rod is fixedly connected to a fixed block, two arc-shaped telescopic rods are fixedly connected to the side wall of the fixed block, and the ends of the two arc-shaped telescopic rods away from the fixed block are rotatably connected to a folding plate;

[0006] The detection mechanism includes a plurality of sliding plates slidably connected to the inner wall of the folding plate, and a lateral pressure instrument is fixedly connected to the side walls of the plurality of sliding plates. A spring is fixedly connected to the side wall of the folding plate, and one end of the spring away from the folding plate is fixedly connected to the side wall of the sliding plate. The end of the pneumatic telescopic rod away from the pneumatic box is rotatably connected to a folding frame, and the end of the folding frame away from the pneumatic telescopic rod is rotatably connected to the inner wall of the folding plate. When the curling edge expands, the adjacent curling edge will expand and squeeze, forcing the side wall of the box door to be in an inclined state. A plurality of lateral pressure instruments and a spring-pressure detector are arranged inside the device. When in use, the electric telescopic rod is installed in the required position, and the box door to be detected is placed directly below the device. After ensuring that the box door corner is aligned with the internal angle detection mechanism, the power supply of the electric telescopic rod is turned on, and the electric telescopic rod generates a downward extension force. At this time, the electric telescopic rod drives the push rod and the piston plate to move downward synchronously. When the pneumatic box contacts the inner wall of the box door, the pneumatic box cannot continue to move, and the electric telescopic rod is extended, and the piston plate will move along the inner wall of the pneumatic box. The folding plate is pushed to the sides by the corresponding folding frame, so that the folding part of the folding plate contacts the inner wall of the negative angle of the box door. As the pneumatic telescopic rod continues to extend outward, the pneumatic telescopic rod will squeeze the folding frame, and the folding frame will push the folding plate to unfold to both ends, so that the folding plate is close to the inner wall of the box door, so that multiple transverse pressure instruments contact the inner wall of the box door. If the curling edge of the box door expands at this time, the side wall of the curling edge of the box door will tilt. At this time, the transverse pressure instrument contacts the inclined surface of the box door. After the transverse pressure instrument contacts the inside of the curling edge of the box door, the reaction force generated will push the sliding plate to move inward along the through hole of the folding plate. At this time, the spring will be stretched and extended. In this process, the longer the spring is pulled outward, the greater the mechanical power generated, and the greater the pressure on the transverse pressure instrument at both ends. By detecting the data sent by multiple transverse pressure instruments, it is effective to measure whether the box door is tilted due to the influence of the curling edge, and indirectly detect whether the box door has deformation problems.

[0007] Preferably, the cleaning assembly includes a fixed plate fixedly connected to the end of the pneumatic telescopic rod away from the pneumatic box, a telescopic air pipe is fixedly connected to the side wall of the fixed plate, and the end of the telescopic air pipe away from the fixed plate is connected to the triangular air box.

[0008] Preferably, the cleaning component also includes an air outlet opened on the side wall of the triangular air box, a sliding blocking frame is slidably connected to the inner wall of the triangular air box, a spring 2 is fixedly connected to the top of the sliding blocking frame, and one end of the spring 2 away from the sliding blocking frame is fixedly connected to the inner wall of the triangular air box.

[0009] Preferably, the cleaning component also includes a roller rotatably connected to the inner wall of the sliding blocking frame, a spring three is fixedly connected to the side wall of the fixed plate, one end of the spring three away from the fixed plate is fixedly connected to the side wall of the triangular air box, a sloped rod is fixedly connected to the side wall of the fixed plate, and a one-way valve is connected to the top of the triangular air box. A cleaning component is arranged inside the equipment by utilizing the force of the above-mentioned air pressure telescopic rod extending outward. When the air pressure telescopic rod extends outward, it will drive the fixed plate to move outward synchronously, and the fixed plate will drive the telescopic air pipe and the triangular air box to move outward, so that the triangular air box contacts the inner wall of the box door. At this time, the triangular air box is blocked and cannot move, and the air pressure telescopic rod drives the fixed plate to continue to move outward, compressing the air inside the telescopic air pipe, so that high-pressure gas is formed inside the telescopic air pipe. As the fixed plate approaches the direction of the triangular air box, the slope of the sloped rod will contact the outer wall of the roller, presenting a cleaning component as shown in the figure. Figure 7 In the state shown, the roller is pushed by the inclined surface of the inclined rod, forcing the sliding blocking frame to move upward along the inner wall of the triangular air box. At this time, the sliding blocking frame will no longer block the air outlet, and the telescopic air pipe and the high-pressure gas inside the triangular air box will be ejected outward through the gap between the sliding blocking frame and the air outlet, and enter the inner wall of the curled edge of the box door, removing impurities remaining inside the box, avoiding internal impurities from remaining, affecting the contact distance between the folding plate and the inner wall of the curled edge, and affecting the detection accuracy of the lateral pressure instrument.

[0010] Preferably, the male angle detection assembly includes a cross fixedly connected to the side wall of the push rod, a plurality of rolling frames fixedly connected to the outer wall of the cross, an L-shaped spring plate slidably connected to the inner wall of the through hole of the cross, and a pulling belt fixedly connected to the bottom of the L-shaped spring plate.

[0011] Preferably, the positive angle detection component also includes a rotating frame rotatably connected to the inner wall of the cross, the outer wall of the pulling belt is rotatably connected to the outer wall of the corresponding rolling frame, and the end of the pulling belt away from the L-shaped spring plate is fixedly connected to the side wall of the rotating frame. Utilizing the rotation characteristics of the above-mentioned L-shaped pressure frame, a longitudinal pressure instrument and a spring four are arranged inside the equipment. When the L-shaped pressure frame contacts the outer wall of the box door curling, the L-shaped pressure frame will drive multiple longitudinal pressure instruments to contact the outer wall of the box door. After multiple longitudinal pressure instruments contact the inside of the box door curling, the longitudinal pressure instruments will move along the through holes of the L-shaped pressure frame The inner wall moves outward, and the longitudinal pressure instrument moves outward, which will drive the corresponding spring four to extend. The longer the extension length of the spring four is, the greater the reaction force generated will be, and the reaction force will directly act on the contact end of the longitudinal pressure instrument. If the curled outer wall of the box door is concave or protrudes at this time, the reaction force on the contact end of the corresponding longitudinal pressure instrument will also change. By detecting the deviation of the data generated by multiple contact ends, it is possible to quickly identify whether the inner wall of the distribution box door is protruding, thereby improving the detection efficiency of the equipment and quickly checking whether there is deformation at the corner of the distribution box door.

[0012] Preferably, the positive angle detection component also includes an L-shaped pressure frame fixedly connected to the bottom of the rotating frame, the inner wall of the through hole of the L-shaped pressure frame is slidably connected with a longitudinal pressure instrument, the side wall of the longitudinal pressure instrument is fixedly connected with a spring four, the end of the spring four away from the longitudinal pressure instrument is fixedly connected to the side wall of the L-shaped pressure frame, the inner wall of the rotating frame is fixedly connected with a turbine spring, and the end of the turbine spring away from the rotating frame is fixedly connected to the inner wall of the cross. Utilizing the characteristic that the electric telescopic rod pushes the push rod to move downward during the above operation, a cross and an L-shaped spring plate are arranged inside the equipment. When the push rod moves downward, the cross will move downward synchronously, and the cross drives the four L-shaped spring plates to move downward, the bottom of the L-shaped spring plate will contact the top of the air pressure box, and the L-shaped spring plate will slide upward along the inner wall of the through hole of the cross, and the L-shaped spring plate will drive the pulling belt to contract. When the pulling belt is pulled, it will drive the rotating frame at the other end to rotate downward with the turbine spring as the center, and the rotating frame drives the L-shaped pressure frame to rotate downward. This process is Figure 8 The process of G→H→Y rotates, and finally forces the L-shaped pressure frame to be close to the outer wall of the door curling, providing a supporting force for the outside of the door curling, avoiding excessive pressure on the inner corner of the door, causing deformation of the curling.

[0013] A detection method for a metering box door opening and closing detection device comprises the following steps:

[0014] S1: When in use, install the electric telescopic rod at the desired position, and place the door to be tested directly under the equipment. After ensuring that the door corner is aligned with the inner corner detection mechanism, turn on the power of the electric telescopic rod.

[0015] S2: The electric telescopic rod generates a downward extension force. At this time, the electric telescopic rod drives the push rod and the piston plate to move downward synchronously. When the air pressure box contacts the inner wall of the box door, the air pressure box cannot move further. The electric telescopic rod extends, and the piston plate slides downward along the inner wall of the air pressure box, forcing the air inside the air pressure box to enter the air pressure telescopic rod.

[0016] S3: Multiple pneumatic telescopic rods extend outward, and the multiple pneumatic telescopic rods drive the folding plate to move around through the corresponding folding frames, so that the folding part of the folding plate contacts the inner wall of the inner corner of the door. As the pneumatic telescopic rods continue to extend outward, the pneumatic telescopic rods will squeeze the folding frames, and the folding frames will push the folding plate to unfold to both ends, so that the folding plate is close to the inner wall of the door.

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

[0018] (1) The present invention utilizes that when the curling edge expands, the adjacent curling edge will expand and squeeze, forcing the side wall of the box door to be in an inclined state. A plurality of lateral pressure instruments and a spring-pressure detector are arranged inside the device. When in use, the electric telescopic rod is installed at the required position, and the box door to be detected is placed directly below the device. After ensuring that the corner of the box door is aligned with the inner corner detection mechanism, the power of the electric telescopic rod is turned on, and the electric telescopic rod generates a downward extension force. At this time, the electric telescopic rod drives the push rod and the piston plate to move downward synchronously. When the air pressure box contacts the inner wall of the box door, the air pressure box cannot continue to move, and the electric telescopic rod extends. The piston plate will slide downward along the inner wall of the air pressure box, forcing the air inside the air pressure box to enter the air pressure telescopic rod. The plurality of air pressure telescopic rods extend outward, and the plurality of air pressure telescopic rods drive the folding plates to move around through the corresponding folding frames, so that the folding The folded part of the stacked plate contacts the inner wall of the negative angle of the door. As the pneumatic telescopic rod continues to extend outward, the pneumatic telescopic rod will squeeze the folding frame, and the folding frame will push the folding plate to unfold to both ends, so that the folding plate is close to the inner wall of the door, so that multiple transverse pressure instruments are in contact with the inner wall of the door. If the curling edge of the door expands at this time, the side wall of the curling edge of the door will tilt. At this time, the transverse pressure instrument contacts the inclined surface of the door. After the transverse pressure instrument contacts the inside of the curling edge of the door, the reaction force generated will push the sliding plate to move inward along the through hole of the folding plate. At this time, the spring will be pulled and extended. In this process, the longer the spring is pulled outward, the greater the mechanical power generated, and the greater the pressure on the transverse pressure instrument at both ends. By detecting the data sent by multiple transverse pressure instruments, it is effective to measure whether the door is tilted due to the influence of the curling edge, and indirectly detect whether the door is deformed.

[0019] (2) The present invention utilizes the force of the above-mentioned pneumatic telescopic rod extending outward, and a cleaning component is arranged inside the equipment. When the pneumatic telescopic rod extends outward, it will drive the fixed plate to move outward synchronously, and the fixed plate will drive the telescopic air pipe and the triangular air box to move outward, so that the triangular air box contacts the inner wall of the box door. At this time, the triangular air box is blocked and cannot move. The pneumatic telescopic rod drives the fixed plate to continue to move outward, compressing the air inside the telescopic air pipe, so that high-pressure gas is formed inside the telescopic air pipe. As the fixed plate approaches the direction of the triangular air box, the inclined surface of the inclined surface rod will contact the outer wall of the roller, presenting a Figure 7 In the state shown, the roller is pushed by the inclined surface of the inclined rod, forcing the sliding blocking frame to move upward along the inner wall of the triangular air box. At this time, the sliding blocking frame will no longer block the air outlet, and the telescopic air pipe and the high-pressure gas inside the triangular air box will be ejected outward through the gap between the sliding blocking frame and the air outlet, and enter the inner wall of the curled edge of the box door, removing impurities remaining inside the box, avoiding internal impurities from remaining, affecting the contact distance between the folding plate and the inner wall of the curled edge, and affecting the detection accuracy of the lateral pressure instrument.

[0020] (3) The present invention utilizes the characteristic that the electric telescopic rod pushes the push rod to move downward during operation. A cross and an L-shaped spring plate are arranged inside the device. When the push rod moves downward, the cross will move downward synchronously. The cross drives the four L-shaped spring plates to move downward. The bottom of the L-shaped spring plate will contact the top of the air pressure box, and the L-shaped spring plate will slide upward along the inner wall of the through hole of the cross. The L-shaped spring plate will drive the pulling belt to contract. When the pulling belt is pulled, it will drive the rotating frame at the other end to rotate downward with the turbine spring as the center. The rotating frame drives the L-shaped pressure frame to rotate downward, and finally forces the L-shaped pressure frame to be close to the outer wall of the door curling, providing a supporting force for the outside of the door curling, thereby avoiding excessive pressure on the inner corner of the door and causing deformation of the curling.

[0021] (4) The present invention utilizes the rotation characteristic of the above-mentioned L-shaped pressure frame, and a longitudinal pressure instrument and a spring four are arranged inside the equipment. When the L-shaped pressure frame contacts the outer wall of the box door curling edge, the L-shaped pressure frame will drive multiple longitudinal pressure instruments to contact the outer wall of the box door. After the multiple longitudinal pressure instruments contact the inner wall of the box door curling edge, the longitudinal pressure instruments will move outward along the inner wall of the through hole of the L-shaped pressure frame. The outward movement of the longitudinal pressure instruments will drive the corresponding spring four to extend. The longer the extension length of the spring four is, the greater the reaction force generated will be, and the reaction force will directly act on the contact end of the longitudinal pressure instrument. If the outer wall of the box door curling edge is concave or protruding at this time, the reaction force received by the contact end of the corresponding longitudinal pressure instrument will also change. By detecting the deviation of the data generated by multiple contact ends, it is possible to quickly identify whether the inner wall of the distribution box door is protruding, thereby improving the detection efficiency of the equipment and quickly checking whether there is deformation at the corner of the distribution box door.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1 - Figure 5The present invention is a metering box door opening and closing detection device, comprising a pneumatic box 1, a piston plate 11 is slidably connected to the inner wall of the pneumatic box 1, four pneumatic telescopic rods 12 are connected through the side wall of the pneumatic box 1, four telescopic rods 13 are fixedly connected to the side wall of the pneumatic box 1, a push rod 14 is fixedly connected to the top of the piston plate 11, an electric telescopic rod 15 is fixedly connected to the top of the push rod 14, a cleaning component 4 is fixedly connected to the top of the pneumatic telescopic rod 12, and a positive angle detection component 5 is fixedly connected to the side wall of the push rod 14;

[0037] The internal angle detection mechanism 2 includes an L-shaped track 21 fixedly connected to the end of the telescopic rod 13 away from the air pressure box 1, the end of the L-shaped track 21 away from the telescopic rod 13 is fixedly connected to a fixed block 22, and two arc-shaped telescopic rods 23 are fixedly connected to the side wall of the fixed block 22, and the ends of the two arc-shaped telescopic rods 23 away from the fixed block 22 are rotatably connected to a folding plate 24;

[0038] The detection mechanism 3 includes a plurality of sliding plates 31 slidably connected to the inner wall of the folding plate 24, a plurality of sliding plates 31 are fixedly connected to the side walls with transverse pressure instruments 32, a spring 33 is fixedly connected to the side wall of the folding plate 24, an end of the spring 33 away from the folding plate 24 is fixedly connected to the side wall of the sliding plate 31, an end of the pneumatic telescopic rod 12 away from the pneumatic box 1 is rotatably connected to a folding frame 34, an end of the folding frame 34 away from the pneumatic telescopic rod 12 is rotatably connected to the inner wall of the folding plate 24, and when the curling edge expands, the adjacent curling edge will expand and squeeze, forcing the side wall of the box door to be The device is in a tilted state, and a plurality of lateral pressure instruments 32 and a spring-33 pressure detector are arranged inside the device. When in use, the electric telescopic rod 15 is installed at the desired position, and the box door to be detected is placed directly below the device. After ensuring that the box door corner is aligned with the inner angle detection mechanism 2, the power of the electric telescopic rod 15 is turned on, and the electric telescopic rod 15 generates a downward extending force. At this time, the electric telescopic rod 15 drives the push rod 14 and the piston plate 11 to move downward synchronously. When the air pressure box 1 contacts the inner wall of the box door, the air pressure box 1 cannot continue to move, and the electric telescopic rod 15 is extended, and the piston plate 11 will move along the air pressure box 1. The inner wall of the pressure box 1 slides downward, forcing the air inside the pressure box 1 to enter the inside of the pressure telescopic rod 12, and the multiple pressure telescopic rods 12 extend outward.

At this time, the spring 1 33 will be pulled and extended. In this process, the longer the spring 1 33 is pulled outward, the greater the mechanical power generated, and the greater the pressure on the lateral pressure instrument 32 at both ends. By detecting the data emitted by multiple lateral pressure instruments 32, it is effective to measure whether the door is tilted due to the influence of the curling, and indirectly detect whether the door is deformed.

When the push rod 14 moves downward, the cross 51 will move downward synchronously, and the cross 51 drives the four L-shaped spring plates 53 to move downward. The bottom of the L-shaped spring plate 53 will contact the top of the air pressure box 1, and the L-shaped spring plate 53 will slide upward along the inner wall of the through hole of the cross 51, and the L-shaped spring plate 53 will drive the pulling belt 54 to contract. When the pulling belt 54 is pulled, it will drive the rotating frame 55 at the other end to rotate downward with the turbine spring 59 as the center, and the rotating frame 55 drives the L-shaped pressing frame 56 to rotate downward. This process is as follows: Figure 8 The process of G→H→Y rotates, and finally forces the L-shaped pressing frame 56 to be closely attached to the outer wall of the door curling, providing a supporting force for the outer side of the door curling, and preventing the inner corner of the door from being over-pressed, causing deformation of the curling.

[0045] The method for using the detection device includes the following steps:

[0046] S1: When in use, install the electric telescopic rod 15 at the desired position, place the door to be detected directly under the device, make sure that the door corner is aligned with the inner angle detection mechanism 2, and then turn on the power of the electric telescopic rod 15;

[0047] S2: The electric telescopic rod 15 generates a downward extension force. At this time, the electric telescopic rod 15 drives the push rod 14 and the piston plate 11 to move downward synchronously. When the air pressure box 1 contacts the inner wall of the box door, the air pressure box 1 cannot move further. The electric telescopic rod 15 extends, and the piston plate 11 slides downward along the inner wall of the air pressure box 1, forcing the air inside the air pressure box 1 to enter the air pressure telescopic rod 12;

[0048] S3: The multiple pneumatic telescopic rods 12 extend outward, and the multiple pneumatic telescopic rods 12 drive the folding plate 24 to move around through the corresponding folding frames 34, so that the folded part of the folding plate 24 contacts the inner wall of the inner corner of the door. As the pneumatic telescopic rods 12 continue to extend outward, the pneumatic telescopic rods 12 will squeeze the folding frames 34, and the folding frames 34 will push the folding plate 24 to unfold to both ends, so that the folding plate 24 is close to the inner wall of the door.

[0049] A specific application of this embodiment is: when in use, the electric telescopic rod 15 is installed in the required position, and the box door to be detected is placed directly under the equipment. After determining that the box door corner is aligned with the inner corner detection mechanism 2, the power of the electric telescopic rod 15 is turned on, and the electric telescopic rod 15 generates a downward extension force. At this time, the electric telescopic rod 15 drives the push rod 14 and the piston plate 11 to move downward synchronously. When the air pressure box 1 contacts the inner wall of the box door, the air pressure box 1 cannot continue to move, and the electric telescopic rod 15 is extended. The piston plate 11 will slide downward along the inner wall of the air pressure box 1, forcing the air inside the air pressure box 1 to enter the air pressure telescopic rod 12, and multiple air pressure telescopic rods 12 are extended outward. Multiple air pressure telescopic rods 12 drive the folding plates 24 to move around through the corresponding folding frames 34, so that the folded part of the folding plates 24 contacts the inner wall of the inner corner of the box door. As the air pressure telescopic rod 12 The folding frame 34 will continue to extend outward, and the pneumatic telescopic rod 12 will squeeze the folding frame 34, and the folding frame 34 will push the folding plate 24 to unfold to both ends, so that the folding plate 24 is close to the inner wall of the box door, so that multiple transverse pressure instruments 32 are in contact with the inner wall of the box door. If the curling edge of the box door expands at this time, the side wall of the curling edge of the box door will tilt. At this time, the transverse pressure instrument 32 is in contact with the inclined surface of the box door. After the transverse pressure instrument 32 contacts the inside of the curling edge of the box door, the reaction force generated will push the sliding plate 31 to move inward along the through hole of the folding plate 24. At this time, the spring 1 33 will be pulled and extended. In this process, the longer the spring 1 33 is pulled outward, the greater the mechanical power generated, and the greater the pressure on the transverse pressure instrument 32 at both ends. By detecting the data sent by multiple transverse pressure instruments 32, it is effective to measure whether the box door is tilted due to the influence of the curling, and indirectly detect whether the box door has a deformation problem.

[0050] By utilizing the force of the pneumatic telescopic rod 12 extending outward, a cleaning component 4 is provided inside the device. When the pneumatic telescopic rod 12 extends outward, it will drive the fixed plate 41 to move outward synchronously, and the fixed plate 41 will drive the telescopic air pipe 42 and the triangular air box 43 to move outward, so that the triangular air box 43 contacts the inner wall of the box door. At this time, the triangular air box 43 is blocked and cannot move. The pneumatic telescopic rod 12 drives the fixed plate 41 to continue to move outward, compressing the air inside the telescopic air pipe 42, so that high-pressure gas is formed inside the telescopic air pipe 42. As the fixed plate 41 approaches the triangular air box 43, the inclined surface of the inclined surface rod 49 will contact the outer wall of the roller 47, presenting a Figure 7 In the state shown, the roller 47 is pushed by the inclined surface of the inclined rod 49, and will force the sliding blocking frame 45 to move upward along the inner wall of the triangular air box 43. At this time, the sliding blocking frame 45 will no longer block the air outlet 44, and the telescopic air pipe 42 and the high-pressure gas inside the triangular air box 43 will be ejected outward through the gap between the sliding blocking frame 45 and the air outlet 44, and enter the inner wall of the curling edge of the box door, removing impurities remaining inside the box, avoiding internal impurities from remaining, affecting the contact distance between the folding plate 24 and the inner wall of the curling edge, and affecting the detection accuracy of the lateral pressure instrument 32.

[0051] Utilizing the characteristic that the electric telescopic rod 15 pushes the push rod 14 to move downward during the above operation, a cross 51 and an L-shaped spring plate 53 are arranged inside the device. When the push rod 14 moves downward, the cross 51 will move downward synchronously, and the cross 51 drives the four L-shaped spring plates 53 to move downward. The bottom of the L-shaped spring plate 53 will contact the top of the air pressure box 1, and the L-shaped spring plate 53 will slide upward along the inner wall of the through hole of the cross 51, and the L-shaped spring plate 53 will drive the pulling belt 54 to contract. When the pulling belt 54 is pulled, it will drive the rotating frame 55 at the other end to rotate downward with the turbine spring 59 as the center, and the rotating frame 55 drives the L-shaped pressing frame 56 to rotate downward. This process is Figure 8The L-shaped pressing frame 56 rotates in the process of G→H→Y, and finally forces the L-shaped pressing frame 56 to be close to the outer wall of the door curling, providing a supporting force for the outer side of the door curling, and avoiding excessive pressure on the inner corner of the door, which causes deformation of the curling. By utilizing the rotation characteristics of the above-mentioned L-shaped pressing frame 56, a longitudinal pressure instrument 57 and a spring 4 58 are arranged inside the equipment. When the L-shaped pressing frame 56 contacts the outer wall of the door curling, the L-shaped pressing frame 56 will drive multiple longitudinal pressure instruments 57 to contact the outer wall of the door. After the multiple longitudinal pressure instruments 57 contact the inside of the door curling, the longitudinal pressure instruments 57 will move along the L-shaped pressing frame 56 through the spring 4 58. The inner wall of the hole moves outward, and the longitudinal pressure instrument 57 moves outward, which will drive the corresponding spring four 58 to extend. The longer the extension length of the spring four 58 is, the greater the reaction force generated will be, and the reaction force will directly act on the contact end of the longitudinal pressure instrument 57. If the curled outer wall of the box door is concave or protrudes at this time, the reaction force on the contact end of the corresponding longitudinal pressure instrument 57 will also change. By detecting the deviation of the data generated by multiple contact ends, it is possible to quickly identify whether the inner wall of the distribution box door is protruding, thereby improving the detection efficiency of the equipment and quickly checking whether there is deformation at the corner of the distribution box door.
