Abstract

The invention relates to the technical field of nut production devices, discloses a nut production device and a production process thereof, and aims to solve the problem that a hexagonal nut is inclined due to residual chippings in a rotary tray fixing groove. When hexagonal nuts are fed, the hexagonal nuts enter a fixing groove and push a power plate and a sliding block I, so that transmission fluid pushes a sliding block II and a supporting plate to replace the bottom face of a rotating material disc fixing groove, and the situation that falling chippings exist on the bottom face of the rotating material disc fixing groove, and consequently the entered hexagonal nuts incline is prevented; when the hexagon nut is driven to the discharging position through the rotating material disc, the tension spring pulls the sliding block II to reset, the reset sliding block II pushes the sliding block I and the power plate to move through the transmission fluid, the power plate conducts auxiliary discharging on the hexagon nut, and the situation that the hexagon nut is attached to the side wall of a fixing groove due to tension of cooling oil when the cooling oil cools is prevented; therefore, the situation that the hexagon nuts are difficult to automatically unload through gravity is avoided.

Description

Technical Field

[0001] This application relates to the field of nut production equipment technology, and in particular to a nut production equipment and its production process. Background Technology

[0002] A nut is a standard part used in conjunction with a bolt or screw to secure components together via its internal threads. Its core function is to provide clamping force and tightly connect multiple parts together. A typical hexagonal nut includes a body, internal threads, a bearing surface, and chamfers. The production of hexagonal nuts generally includes steps such as raw material processing and preparation, cold heading, tapping, and heat treatment. The tapping process involves using a tap on a tapping machine to machine the threads on the inner end face of the nut.

[0003] A tapping machine typically includes a frame, a rotating material tray, a fixing mechanism, a feeding system, a tapping system, and a control system. When tapping a hexagonal nut, the fixing mechanism secures the nut in the fixing groove of the rotating material tray. The tap of the tapping system then taps the inner wall of the nut. After tapping, the rotating material tray rotates the nut, causing it to fall from the unloading point. As the nut falls, the chips that fell onto it during the tapping process drop into the fixing groove of the rotating material tray. When subsequent hexagonal nuts enter the groove, the chips at the bottom of the groove lift the nut, causing it to tilt. The axis of the nut and the axis of the tap are no longer aligned, resulting in a misalignment of the internal thread of the nut. Summary of the Invention

[0004] This application proposes a nut production device and its production process, which has the advantage of preventing the hexagonal nuts from tilting due to debris in the rotating material tray fixing groove, thereby solving the problem of hexagonal nuts tilting due to residual debris in the rotating material tray fixing groove.

[0005] To achieve the above objectives, this application adopts the following technical solution: a nut production device and its production process, comprising a frame, a stepper motor, a rotating material tray, a lower plate, a cylinder, a fixed head, a vibrating plate, a conveyor belt, a tapping system, and a control system. The upper edge of the rotating material tray is provided with several fixed grooves. The sidewalls of the fixed grooves are provided with a power groove and a bottom plate groove. The power groove and the bottom plate groove are connected at their ends near the axis. The power groove and the bottom plate groove are provided with: a sliding block I, slidably and sealed within the power groove; a power plate, fixedly connected to the sliding block I, penetrating the sidewall of the fixed groove and extending outwards; a sliding block II, slidably and sealed within the bottom plate groove; a support plate, fixedly connected to the sliding block II and penetrating the sidewall of the fixed groove; and several tension springs, one end fixedly connected to the sliding block II and the other end fixedly connected to the inner wall of the bottom plate groove. The power groove and the bottom plate groove are filled with transmission fluid.

[0006] Furthermore, a limit block is fixedly installed on the inner wall of the bottom plate groove on the side where the sliding block II is connected to the tension spring.

[0007] Furthermore, the tension spring is always in a stretched state.

[0008] Furthermore, a detection hole is provided in the lower end face of the fixed groove of the rotating material tray, and a connecting hole is provided in the rotating material tray to connect the detection hole and the bottom plate groove. The connecting hole is filled with transmission fluid. The detection hole is provided with: a detection column and an elastic block, which are slidably and sealed in the detection hole. The elastic block is fixedly connected to the upper end face of the detection column; two conductor blocks are embedded in the side wall of the detection hole; an audible and visual alarm is fixedly installed at the top of the rotating material tray, and the audible and visual alarm, conductor blocks and control system are electrically connected.

[0009] Furthermore, a limiting arc block is fixedly installed at the bottom end of the detection hole.

[0010] Furthermore, the length of the detection column is greater than the distance between the two conductor blocks.

[0011] Furthermore, a rubber block is fixedly installed at the bottom of the detection column, and the rubber block is slidably and sealingly installed inside the detection hole.

[0012] Furthermore, a compensation groove is provided in the rotating tray above the detection hole, and a compensation block is slidably and sealed in the compensation groove. The bottom end of the compensation block is fixedly connected to the top end of the elastic block.

[0013] Furthermore, the width of the compensation block is smaller than the width of the fixing groove, and after the compensation block moves to the designated position, there is a certain gap between the side wall of the compensation block and the side wall of the support plate.

[0014] Furthermore, the following steps are included: S1. When the hexagonal nut is pushed into the fixed groove of the rotating material tray, the hexagonal nut squeezes the power plate, causing the sliding block I to squeeze the transmission fluid. The transmission fluid pushes the sliding block II and the support plate to move, causing the support plate to move into the fixed groove. The extended support plate supports the hexagonal nut. S2. After tapping is completed, the rotating disc rotates as a whole. The tension spring in the bottom plate groove pulls the sliding block II and the support plate to reset. During the process of the support plate resetting and entering the bottom plate groove, the debris on the support plate is scraped off and the debris on the support plate is cleaned. S3. The reset sliding block II pushes the sliding block I and the power plate to move through the transmission fluid, so that the power plate pushes the side wall of the hexagonal nut to assist the hexagonal nut in unloading. S4. During feeding, the hexagonal nut squeezes the power plate and sliding block I. In the initial process, sliding block I squeezes the transmission fluid in the power groove, causing the transmission fluid to push sliding block II and support plate. At the same time, the transmission fluid pushes the detection column, elastic block and compensation block upward through the connecting hole. The upward-extending compensation block generates an upward supporting force on the hexagonal nut. S5. When the cylinder reaches the tapping station, the output shaft pushes the fixed head to fix the fixed head to the hexagonal nut. When there is wear on the side wall of the fixed groove, the distance that the fixed head pushes the hexagonal nut to squeeze the power plate increases. After the support plate and the compensation block reach the designated position, the hexagonal nut continues to push the power plate until the power plate is pushed into the power groove as a whole. At this time, the transmission fluid pushed by the power plate and sliding block I enters the detection hole through the connecting hole. The transmission fluid pushes the detection column, causing the detection column to squeeze the elastic block. S6. If the wear of the fixed groove sidewall is within the specified range, the transmission fluid will push the detection column upward a small distance, and the detection column will not contact the two conductor blocks on the detection hole sidewall at the same time. If the wear of the fixed groove sidewall is greater than the specified range, the transmission fluid will push the detection column upward a large distance, and the detection column will contact the two conductor blocks on the detection hole sidewall at the same time, energizing the audible and visual alarm and causing the audible and visual alarm to generate an alarm.

[0015] This application has the following beneficial effects: 1. The nut production device and its production process provided in this application, when feeding hexagonal nuts onto a vibrating plate and conveyor belt, the hexagonal nuts enter the fixed groove of a rotating material plate, causing the hexagonal nuts to push the power plate and sliding block I, thereby causing the transmission fluid to push the sliding block II and support plate, replacing the bottom surface of the fixed groove of the rotating material plate, preventing the presence of falling debris on the bottom surface of the fixed groove of the rotating material plate, which would cause the entering hexagonal nuts to tilt, thereby avoiding the tilting of the internal threads of the processed hexagonal nuts.

[0016] 2. The nut production device and its production process provided in this application involve rotating a material tray to move a hexagonal nut to the unloading point. A tension spring pulls the sliding block II to reset. The reset sliding block II pushes the sliding block I and the power plate to move through the transmission fluid, so that the power plate assists in unloading the hexagonal nut. This prevents the hexagonal nut from sticking to the side wall of the fixed groove due to the tension of the cooling oil when it is being cooled, thereby avoiding the difficulty of automatically unloading the hexagonal nut by gravity.

[0017] 3. The nut production device and its production process provided in this application involve feeding a hexagonal nut. The hexagonal nut pushes the power plate and sliding block I, and the transmission fluid pushes the sliding block II and support plate to the designated position. If the inner wall of the fixed groove is worn, the hexagonal nut will continue to push the power plate and sliding block I. At this time, the transmission fluid pushes the detection column upward through the connecting hole. When the fixed groove is worn significantly, the detection column moves upward to a larger position. At this time, the detection column connects the two conductor blocks, which powers the audible and visual alarm, causing the audible and visual alarm to sound an alarm and reminding the staff that the side wall of the fixed groove is severely worn and the rotating material tray needs to be replaced.

[0018] 4. The nut production device and its production process provided in this application, when feeding hexagonal nuts, the hexagonal nuts push the power plate and sliding block I, and the transmission fluid pushes the sliding block II and the support plate to the designated position. During this process, the transmission fluid pushes the rubber block, detection column, elastic block and compensation block upward through the connecting hole, so that the compensation block fills the pit between the support plate and the fixed head, preventing the hexagonal nuts from getting stuck in the pit between the support plate and the fixed head during feeding, thus affecting the feeding of the hexagonal nuts.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example 1 Please see Figure 1 and Figure 2A nut production device and its production process include a frame 1, a rotating material tray 2, a lower plate 3, a fixing mechanism 4, a feeding system, a tapping system 6, and a control system 7. A stepper motor (not shown in the figure, a conventional structure) is fixedly installed inside the frame 1. The output shaft of the stepper motor passes through the upper end face of the frame 1 and extends out. The lower plate 3 is fixedly installed at the middle position of the upper end face of the frame 1. The lower plate 3 is movably sleeved on the output shaft of the stepper motor, and the rotating material tray 2 is fixedly sleeved on the output shaft of the stepper motor. The rotating material tray 2 is located directly above the lower plate 3. Several fixing slots 21 are arranged in a circular array at the edge of the upper end face of the rotating material tray 2. A fixing mechanism 4 is fixedly installed on the upper end face of the frame 1 and on one side of the rotating material tray 2. The fixing mechanism 4 includes a cylinder 41 and a fixing head 42. The cylinder 41 is fixedly installed on the upper end face of the frame 1, and the fixing head 42 is fixedly connected to the output end of the cylinder 41. The fixing head 42 points towards the axis of the rotating material tray 2. Two material-stopping arc blocks 31 are fixedly installed on the upper end face of the lower plate 3, and the two material-stopping arc blocks 31 are located on both sides of the axis of the fixed head 42. A guide hopper 11 is fixedly installed on the side wall of the frame 1, and the guide hopper 11 is used to receive the nuts discharged from the fixed groove 21 of the rotating material plate 2. A tapping system 6 is fixedly installed on the upper end face of the frame 1 and on the other side of the rotating material plate 2. A tap 61 for tapping the nuts is fixedly installed on the output end of the tapping system 6. A feeding system is fixedly installed on the upper end face of the frame 1. The feeding system includes a vibrating plate 51 and a conveyor belt 52. The vibrating plate 51 is fixedly installed on the upper end face of the frame 1. One end of the conveyor belt 52 is connected to the discharge port of the vibrating plate 51, and the other end of the conveyor belt 52 is connected to the fixed groove 21 at the feeding point of the rotating material plate 2. A control system 7 is fixedly installed on the side wall of the frame 1. The control system 7 is electrically connected to the stepper motor, vibrating plate 51, conveyor belt 52, cylinder 41 and tapping system 6 inside the frame 1.

[0024] Please see Figures 1-6The rotating material tray 2 has a power groove 22 and a bottom plate groove 23 on the side wall of the fixing groove 21. The power groove 22 is located directly above the bottom plate groove 23. The length direction of the power groove 22 and the bottom plate groove 23 points towards the axis of the rotating material tray 2. The ends of the power groove 22 and the bottom plate groove 23 near the axis are connected. The power groove 22 and the bottom plate groove 23 are provided with a bottom-changing mechanism for changing the lower end face of the fixing groove 21. The bottom-changing mechanism includes a power plate 81, a sliding block I 82, a support plate 83, a sliding block II 84, and a tension spring 85. The sliding block I 82 is slidably and sealed in the power groove 22. A power plate 81 is fixedly connected to one end of the sliding block I 82 facing the outside of the fixed groove 21. The power plate 81 passes through the side wall of the fixed groove 21 and extends out. A sliding block II 84 is slidably and sealed in the bottom plate groove 23. A support plate 83 is fixedly connected to one end of the sliding block II 84 facing the outside of the fixed groove 21. The support plate 83 passes through the side wall of the fixed groove 21. Several tension springs 85 are fixedly connected to the other end of the sliding block II 84. The other end of the tension springs 85 is fixedly connected to the inner wall of the bottom plate groove 23. The power groove 22 and the bottom plate groove 23 are filled with transmission fluid. In addition, a limiting block is fixedly installed on the inner wall of the base plate groove 23 on the side where the sliding block II 84 is connected to the tension spring 85. The limiting block is used to limit the sliding block II 84 and the support plate 83, so that the side wall of the support plate 83 and the side wall of the fixed groove 21 are on the same vertical plane. The tension spring 85 is always in a stretched state. The stretched tension spring 85 provides a reset force to the sliding block II 84 and the support plate 83. When there is no external force, the side wall of the support plate 83 and the side wall of the fixed groove 21 are on the same vertical plane.

[0025] When tapping hexagonal nuts using the nut production device, the hexagonal nut blank is placed in the vibrating plate 51 and fed by the vibrating plate 51 and the conveyor belt 52. Simultaneously, the stepper motor in the frame 1 drives the rotating material tray 2 to rotate intermittently. When the hexagonal nut in the conveyor belt 52 is pushed into the fixed groove 21 of the rotating material tray 2, the hexagonal nut will squeeze the power plate 81 in the fixed groove 21, causing the power plate 81 to push the sliding block I 82 to squeeze the transmission fluid. The transmission fluid in the power groove 22 enters the bottom plate groove 23, thereby... Pushing the sliding block II 84 and the support plate 83 to move the support plate 83 into the fixed groove 21, when the hexagonal nut pushes the power plate 81 into the power groove 22, the support plate 83 extends to its maximum position. At this time, the extended support plate 83 supports the hexagonal nut. There are no tapping debris on the upper surface of the newly extended support plate 83, thus preventing the hexagonal nut from tilting due to falling debris on the bottom surface of the fixed groove 21 of the rotating material tray 2, thereby avoiding tilting of the internal thread of the machined hexagonal nut.

[0026] After the hexagonal nut is tapped, the stepper motor in the frame 1 drives the rotating material tray 2 to rotate as a whole. When the opening of the fixed groove 21 is no longer blocked by the material-stopping arc block 31, the tension spring 85 in the bottom plate groove 23 pulls the sliding block II 84 and the support plate 83 to reset. During the process of the support plate 83 resetting and entering the bottom plate groove 23, the debris on the support plate 83 is scraped off, thereby cleaning the debris on the support plate 83. In addition, the reset sliding block II 84 pushes the sliding block I 82 and the power plate 81 to move through the transmission fluid, so that the power plate 81 extends into the fixed groove 21, thereby pushing the side wall of the hexagonal nut with the power plate 81 to assist the hexagonal nut in unloading. This prevents the hexagonal nut from sticking to the side wall of the fixed groove 21 due to the tension of the cooling oil when the tapping is sprayed out, thus avoiding the difficulty of the hexagonal nut being unloaded automatically by gravity.

[0027] Example 2 Example 2 is a further improvement based on Example 1.

[0028] Unlike Example 1, please refer to Figures 1-7 A detection hole 24 is provided in the lower end face of the fixed groove 21 of the rotating material tray 2. The side wall of the detection hole 24 is provided with an insulating layer. A connecting hole 25 is provided in the rotating material tray 2. The connecting hole 25 is used to connect the bottom end of the detection hole 24 and the bottom plate groove 23. The connecting hole 25 is filled with transmission fluid. A limiting arc block 26 is fixedly installed at the bottom end of the detection hole 24. The limiting arc block 26 will not block the connection between the detection hole 24 and the connecting hole 25. A detection mechanism for detecting the wear of the side wall of the fixed groove 21 is installed in the detection hole 24. The detection mechanism includes a detection column 92. The detection column 92 and the elastic block 93 are slidably and sealed in the detection hole 24. The elastic block 93 is fixedly connected to the upper end face of the detection column 92. Two conductor blocks 94 are embedded in the side wall of the detection hole 24 and the two conductor blocks 94 are at different heights. Under normal conditions, the detection column 92 will not contact the two conductor blocks 94 at the same time. The audible and visual alarm 95 is fixedly installed at the middle position of the top of the rotating material tray 2. The audible and visual alarm 95, the conductor block 94 and the control system 7 are electrically connected.

[0029] When the hexagonal nut is being fed, the vibrating disc 51 and the conveyor belt 52 push the hexagonal nut into the fixed groove 21 of the rotating material tray 2. When it reaches the tapping station, the output shaft of the cylinder 41 pushes the fixed head 42, causing the fixed head 42 to press against the side wall of the hexagonal nut. At this time, the fixed head 42 pushes the hexagonal nut, causing the hexagonal nut to squeeze the power plate 81 in the fixed groove 21 until the power plate 81 is pushed into the power groove 22 as a whole, and the hexagonal nut is fixed. When there is wear on the side wall of the fixed groove 21, the distance that the fixed head 42 pushes the hexagonal nut to squeeze the power plate 81 increases, that is, the distance that the power plate 81 pushes the sliding block I 82 into the power groove 22 increases. In the initial process, the sliding block I 82 squeezes the transmission fluid in the power groove 22, causing the transmission fluid to push the sliding block II 84 and the support plate 83 until the support plate 83 extends to the designated position. At this time, the hexagonal nut continues to push the power plate 81 until the power plate is fully pushed into the power groove 22. 81 is pushed into the power tank 22. During this process, the transmission fluid driven by the power plate 81 and sliding block I 82 enters the detection hole 24 through the connecting hole 25. The transmission fluid pushes the detection column 92 in the detection hole 24, causing the detection column 92 to squeeze the elastic block 93. If the wear of the side wall of the fixed tank 21 is within the specified range, the transmission fluid pushes the detection column 92 to move upward a small distance. At this time, the detection column 92 will not contact the two conductor blocks 94 on the side wall of the detection hole 24 at the same time, that is, the audible and visual alarm 95 will not be energized. If the wear of the side wall of the fixed tank 21 is greater than the specified range, the transmission fluid pushes the detection column 92 to move upward a large distance. At this time, the detection column 92 contacts the two conductor blocks 94 on the side wall of the detection hole 24 at the same time, that is, the audible and visual alarm 95 is energized, thereby causing the audible and visual alarm 95 to sound an alarm, reminding the staff that the side wall of the fixed tank 21 is severely worn and the rotating material plate 2 needs to be replaced.

[0030] It should be noted that the length of the detection column 92 is greater than the distance between the two conductor blocks 94. When wear occurs on the side wall of the fixed groove 21, during the feeding process of the hexagonal nut, the displacement of the power plate 81 and the sliding block I 82 by the hexagonal nut increases. At this time, after the transmission fluid pushes the sliding block II 84 and the support plate 83 to the designated position, the transmission fluid in the power groove 22 and the bottom plate groove 23 is further squeezed, so that the transmission fluid enters the detection hole 24 through the connecting hole 25, pushing the detection column 92 to squeeze the elastic block 93. When the wear degree is greater than the error range, it is ensured that the upward-moving detection column 92 can contact the two conductor blocks 94 at the same time, and powering on the audible and visual alarm 95.

[0031] In addition, a rubber block 91 is fixedly installed at the bottom of the detection column 92, and the rubber block 91 is slidably and sealed in the detection hole 24. The rubber block 91 is used to prevent the detection column 92 from contacting the transmission fluid. The rubber block 91 and the elastic block 93 are used to insulate and isolate the detection column 92.

[0032] Example 3 Example 3 is a further improvement based on Example 2.

[0033] Unlike Example 2, please refer to Figures 1-7 A compensation groove 27 is provided in the rotating material tray 2 above the detection hole 24. A compensation block 28 is slidably and sealed in the compensation groove 27. The bottom end of the compensation block 28 is fixedly connected to the top end of the elastic block 93. The width of the compensation block 28 is smaller than the width of the fixed groove 21. After the compensation block 28 moves to the designated position, there is a certain gap between the side wall of the compensation block 28 and the side wall of the support plate 83.

[0034] When feeding hexagonal nuts, the vibrating plate 51 and the conveyor belt 52 push the hexagonal nuts into the fixed groove 21 of the rotating material tray 2, causing the hexagonal nuts to squeeze the power plate 81 in the fixed groove 21. In the initial process, the sliding block I 82 squeezes the transmission fluid in the power groove 22, causing the transmission fluid to push the sliding block II 84 and the support plate 83. At the same time, the transmission fluid enters the detection hole 24 through the connecting hole 25, pushing the detection column 92, the elastic block 93 and the compensation block 28 upward until the support plate 83 and the compensation block 28 reach the designated position, that is, the compensation block 28 extends out of the compensation groove 27. At this time, the upwardly extending compensation block 28 generates an upward supporting force on the hexagonal nuts, preventing the hexagonal nuts that have entered the fixed groove 21 from getting stuck on the side wall of the support plate 83 and hindering the feeding of the hexagonal nuts.

[0035] A manufacturing process for a nut manufacturing apparatus includes the following steps: S1. When tapping hexagonal nuts using the nut production device, the vibrating plate 51 and the conveyor belt 52 feed the hexagonal nuts. At the same time, the stepper motor in the frame 1 drives the rotating material plate 2 to rotate intermittently. S2. When the hexagonal nut is pushed into the fixed groove 21 of the rotating material tray 2, the hexagonal nut squeezes the power plate 81 in the fixed groove 21, causing the power plate 81 to push the sliding block I 82 to squeeze the transmission fluid. The transmission fluid pushes the sliding block II 84 and the support plate 83 to move, causing the support plate 83 to move into the fixed groove 21. The extended support plate 83 supports the hexagonal nut, and there are no tapping debris on the upper surface of the newly extended support plate 83. S3. After tapping is completed, the stepper motor in the frame 1 drives the rotating material tray 2 to rotate as a whole. When the opening of the fixed groove 21 is no longer blocked by the material blocking arc block 31, the tension spring 85 in the bottom plate groove 23 pulls the sliding block II 84 and the support plate 83 to reset. During the process of the support plate 83 resetting and entering the bottom plate groove 23, the debris on the support plate 83 is scraped off, and the debris on the support plate 83 is cleaned. S4. The reset sliding block II 84 pushes the sliding block I 82 and the power plate 81 to move through the transmission fluid, so that the power plate 81 pushes the side wall of the hexagonal nut to assist the hexagonal nut in unloading. S5. When the hexagonal nut is being fed, the hexagonal nut squeezes the power plate 81 and sliding block I 82 in the fixing groove 21. In the initial process, the sliding block I 82 squeezes the transmission fluid in the power groove 22, so that the transmission fluid pushes the sliding block II 84 and the support plate 83. At the same time, the transmission fluid enters through the connecting hole 25 to push the detection column 92, the elastic block 93 and the compensation block 28 to move upward. The upwardly extended compensation block 28 generates an upward supporting force on the hexagonal nut. S6. When the tapping station is reached, the output shaft of the cylinder 41 pushes the fixing head 42, so that the fixing head 42 presses against the side wall of the hexagonal nut. The fixing head 42 pushes the hexagonal nut to fix it. When there is wear on the side wall of the fixing groove 21, the distance that the fixing head 42 pushes the hexagonal nut to squeeze the power plate 81 increases. After the support plate 83 and the compensation block 28 reach the designated position, the hexagonal nut continues to push the power plate 81 until the power plate 81 is pushed into the power groove 22 as a whole. At this time, the transmission fluid pushed by the power plate 81 and the sliding block I 82 enters the detection hole 24 through the connecting hole 25. The transmission fluid pushes the detection column 92, so that the detection column 92 squeezes the elastic block 93. S7. If the wear of the side wall of the fixed groove 21 is within the specified range, the transmission fluid will push the detection column 92 to move upward a small distance. At this time, the detection column 92 will not contact the two conductor blocks 94 on the side wall of the detection hole 24 at the same time, that is, the audible and visual alarm 95 will not be energized. If the wear of the side wall of the fixed groove 21 is greater than the specified range, the transmission fluid will push the detection column 92 to move upward a large distance. At this time, the detection column 92 will contact the two conductor blocks 94 on the side wall of the detection hole 24 at the same time, energizing the audible and visual alarm 95 and causing the audible and visual alarm 95 to generate an alarm.
