Description

Technical Field

[0001] This application relates to the technical field of inspection devices, and specifically relates to a safety inspection device. Background Art

[0002] Industrial safety inspection devices are used for the safety monitoring of industrial plants and production equipment. They play an important role in providing inspection information to safety personnel in a timely manner, and have functions such as accident prevention and control, timely loss prevention, and subsequent liability tracking. Industrial security generally monitors physical signals in the area through monitoring devices and feeds back monitoring information to safety personnel in a timely manner through security terminals, such as monitoring images.

[0003] When the existing monitoring devices for safety inspection are in use, they move on the track to inspect the specified area. However, during operation, they are easily contaminated by dust in the air, and when the device is used for a long time, dust is also likely to accumulate on the lens of the monitoring device, resulting in poor monitoring effects.

[0004] Therefore, the present invention proposes a safety inspection device to improve this problem. Summary of the Invention

[0005] The purpose of this application is to provide a safety inspection device to solve the problems in the above background art.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0008] A suspension plate, on which a track groove is provided;

[0009] A moving plate, on which track wheels rollingly engaged with the track groove are installed, and a camera is installed on the moving plate;

[0010] An air guide cylinder, installed on the moving plate, one end of the air guide cylinder faces the traveling direction of the moving plate, and the other end faces the camera. An electrostatic plate is installed on the moving plate, and opposite charges for adsorbing dust are attached to the electrostatic plate;

[0011] A scraping plate, slidably installed on the moving plate, the scraping plate is in contact with the surface of the electrostatic plate, and dust collecting boxes are installed below both ends of the electrostatic plate on the moving plate.

[0012] Further, the static plate is arc-shaped, and the distance from the horizontal planes where the two ends of the static plate are located to the horizontal plane where the camera is located is less than the distance from the horizontal plane where the lowest point of the static plate is located to the horizontal plane where the camera is located. A rack is installed on the suspension plate, and a gear set is rotatably installed on the moving plate. One of the gears of the gear set meshes with the rack, and a hinged rod is hinged to another gear. A sliding plate is slidably installed on the moving plate, the free end of the hinged rod is hinged to the sliding plate, a connecting spring is installed on the sliding plate, a connecting frame is installed at the free end of the connecting spring, and a friction roller in contact with the static plate is rotatably installed on the connecting frame. The scraping plate is installed on the connecting frame through a spring rope.

[0013] Further, the moving plate includes a moving part and a mounting part, and the camera is installed on the mounting part. A concentration box is installed on the moving part, the dust collection box is installed on the concentration box through a connecting rod, and a cavity for communicating the dust collection box and the concentration box is provided on the connecting rod. A fan is rotatably installed in the concentration box, and a filter plate is installed above the fan in the concentration box.

[0014] Further, a mounting rod is installed on the air guide tube, and the mounting rod is connected to the mounting part. An auxiliary rod is also installed on the air guide tube, and an insertion rod is slidably installed on the auxiliary rod through a sliding spring. A surrounding frame is installed on the moving part, and insertion holes for accommodating the insertion rod are provided on the surrounding frame and the concentration box.

[0015] Further, the concentration box includes a housing and a cover plate. An insertion plate is installed on the housing, and a contact rod is slidably installed on the cover plate through a contact spring. A contact hole for accommodating the contact rod is provided on the insertion plate. When the concentration box is connected to the moving part, the end of the contact rod abuts against the side wall of the mounting part.

[0016] Further, a rotating column is installed on the mounting part. One of the gears of the gear set is rotatably connected to the rotating column. An oil storage cavity is provided on the rotating column, and an oil outlet is provided on the rotating column. A shielding shell that is movably inserted into the oil outlet is slidably installed in the oil storage cavity. A notch is provided on the shielding shell, and a return spring is installed between the oil storage cavity and the shielding shell. An oil passage is provided on the gear of the gear set that is rotatably connected to the rotating column. When the inner diameter of the gear abuts against the shielding shell, the notch is located in the oil outlet. When the shielding shell communicates with the oil passage, the notch communicates with the oil passage.

[0017] Further, the end face of the shielding shell facing away from the inner end of the oil storage cavity is an arc surface.

[0018] Further, a plurality of extension rods are installed on the mounting part, and insertion rods are also slidably installed on the extension rods through sliding springs. An extension plate is installed on the insertion rod, and a unified rod is installed between adjacent extension plates.

[0019] Furthermore, a vertical groove is formed on the cover plate, and a vertical block for slidingly inserting into the vertical groove is installed on the accommodating shell.

[0020] Furthermore, a guide groove is provided on the mounting portion, and a guide block which is slidably matched with the guide groove is installed on the sliding plate.

[0021] The beneficial effects of this application are as follows:

[0022] 1. When the present application is in use, the camera moves on the hanging plate with the moving plate through the track wheels to inspect a specific area. During the process, the airflow generated when the device moves forward is guided to the camera through the air guide tube, so that the airflow can blow to the camera more concentratedly. An electrostatic plate is installed on the moving plate. When the airflow blows dust off the camera lens, the adsorption of opposite charges on the electrostatic plate reduces the possibility of dust adhering to the camera lens again, and reduces the possibility of blurring the monitoring screen due to dust when the device is in use.

[0023] 2. When the device of the present application is in use, when the moving plate moves on the hanging plate, the moving plate and the hanging plate move relative to each other, so that the rack can drive the gear in the gear set to rotate, and then the rotation of the gear drives the hinged rod to drive the sliding plate, causing the sliding plate to drive the friction roller and the scraper plate to reciprocate on the electrostatic plate. During the process, the scraper plate scrapes the dust on the electrostatic plate, and the friction roller rubs against the electrostatic plate, so that the heterogeneous charges on the electrostatic plate are supplemented, thereby increasing the practicality of the device.

[0024] 3. In the present application, the fan is driven by a motor or other power source. The fan is installed at the bottom of the centralizing box. A hole is opened at the bottom of the centralizing box for air flow in and out. When the device is in use, air is sucked into the centralizing box by the fan. Since the air flow has a low pressure when the flow rate is fast, the air pressure in the centralizing box is lower than the air pressure in the dust collecting box, so that dust can enter the centralizing box through the cavity of the connecting rod. The filter plate is located above the fan to block the dust, reducing the possibility of dust contacting the fan. The dust is further collected and stored in the centralizing box. The installation position of the connecting rod reduces the possibility of dust leaking out of the centralizing box, thereby reducing the possibility of dust being raised again, thereby increasing the practicality of the device.

[0025] 4. In this application, the surrounding frame is used to accommodate the centralized box. When the device is installed, the end of the centralized box is inserted into the interior of the surrounding frame. During this process, the inner wall of the surrounding frame closely adheres to the outer wall of the centralized box, initially connecting the centralized box and reducing the possibility of the centralized box falling. During this process, the insertion rod is pulled to slide away from the surrounding frame. When the insertion hole on the centralized box aligns with the insertion hole on the surrounding frame, the insertion rod is released, and the sliding spring's reset force pushes the insertion rod into the insertion hole. By the insertion rod's side wall blocking the inner wall of the insertion hole, the tendency of the centralized box to move away from the moving part is restricted, increasing the stability of the centralized box during use. When the device has been used for some time, the insertion rod is slid to separate it from the insertion hole, disassembling the centralized box from the moving part, and cleaning the interior of the centralized box through the passage on it, increasing the practicality of the device.

Detailed implementation mode

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0039] Embodiment 1

[0040] As Figure 1 - Figure 11 shown, a safety inspection device proposed in Embodiment 1 of the present application includes:

[0041] A suspension plate 1, on which a track groove 101 is provided. The suspension plate 1 has two straight plates and two arc plates for connecting the two ends of the straight plates, so that the shape of the suspension plate 1 is similar to the shape of a runway. The inner circle of the suspension plate 1 is a specific area to be inspected;

[0042] A moving plate 2, on which a track wheel 102 that is in rolling fit with the track groove 101 is installed. A camera 201 is installed on the moving plate 2. As Figure 6 shown, a hole is provided in the moving plate 2. A plate body is installed in the hole through a spring. The track wheel 102 is installed on the plate body. The position of the track wheel 102 is adjusted by the deformation of the spring, so that when the track wheel 102 moves in the track groove 101, it can turn smoothly. The track wheel 102 can be driven by a motor or other power sources, and the specific area is monitored and inspected by the camera 201;

[0043] The air guide tube 3 is installed on the moving plate 2. One end of the air guide tube 3 faces the advancing direction of the moving plate 2, and the other end faces the camera 201. An electrostatic plate 4 is installed on the moving plate 2, and opposite charges for adsorbing dust are attached to the electrostatic plate 4. The air guide tube 3 is L-shaped, with one opening facing the advancing direction of the moving plate 2 and the other opening located above the camera 201. A flared tube is installed on the air guide tube 3. The diameter of the flared tube in the direction away from the air guide tube 3 is larger than the diameter at its connection with the air guide tube 3. When the moving plate 2 is moving, air flow can enter the air guide tube 3 through the flared tube. When it moves into the air guide tube 3, due to the narrowing of the diameter of the flared tube, the air flow speed increases, and through the guidance of the air guide tube 3, the air flow can blow the dust on the lens of the camera 201, reducing the possibility of dust adhering to the lens of the camera 201, and reducing the possibility that the inspection result is damaged due to dust blockage when the device conducts inspection. By cleaning the lens with air flow, the possibility of affecting the monitoring effect of the camera 201 is reduced;

[0044] When the dust is blown by the air flow, the electrostatic plate 4 is located below the camera 201. Through the blowing of the air flow and the action of gravity, the blown dust moves towards the electrostatic plate 4. The opposite charges on the electrostatic plate 4 are the static electricity in colloquial terms. The blown dust is adsorbed through the adsorption of static electricity, reducing the possibility of the dust being lifted up to the camera 201 again, and increasing the practicability of the device;

[0045] The scraping plate 5 is slidably installed on the moving plate 2. The scraping plate 5 is in contact with the surface of the electrostatic plate 4. Dust collection boxes 6 are installed below both ends of the electrostatic plate 4 on the moving plate 2. When the dust is adsorbed on the electrostatic plate 4, in order to reduce the situation where excessive dust accumulation causes the electrostatic plate 4 to have a weak adsorption ability for the dust above the dust pile, the scraping plate 5 reciprocally slides on the electrostatic plate 4, and the dust adsorbed by the electrostatic plate 4 is scraped to fall into the dust collection box 6. Because the dust falling on the electrostatic plate 4 will form a dust cluster under the influence of static electricity, when the scraping plate 5 scrapes it, the dust can fall into the dust collection box 6 in a cluster, reducing the possibility of the dust being lifted up again during the process of falling into the dust collection box 6, and increasing the feasibility of the device;

[0046] Compared with the prior art, when in use, the camera 201 moves on the hanging plate 1 through the track wheels 102 along with the moving plate 2 to conduct inspection on a specific area. During the process, the air flow generated when the device advances is guided to the camera 201 through the air guide tube 3, so that the air flow can blow towards the camera 201 more concentratedly. An electrostatic plate 4 is installed on the moving plate 2. When the air flow blows the dust off the lens of the camera 201, through the adsorption of the opposite charges on the electrostatic plate 4, the possibility of the dust adhering to the lens of the camera 201 again is reduced, and the possibility that the monitoring picture is blurred due to dust during the use of the device is reduced.

[0047] Example 2

[0048] As Figure 2 , Figure 3 and Figure 7 shown, Example 2 further discloses the moving plate 2, the static plate 4, the scraping plate 5 and the dust collecting box 6 on the basis of Example 1. In Example 2, the static plate 4 is arc-shaped. The distance from the horizontal plane where the two ends of the static plate 4 are located to the horizontal plane where the camera 201 is located is less than the distance from the horizontal plane where the lowest point of the static plate 4 is located to the horizontal plane where the camera 201 is located. The two ends of the static plate 4 are upturned. As Figure 7 shown, the arc diameter of the static plate 4 is larger than the arc diameter of the lens of the camera 201, so that the static plate 4 can block the periphery of the lens of the camera 201 in a large range while reducing the blockage of the shooting range of the camera 201, increasing the practicability of the device;

[0049] A rack 401 is installed on the suspension plate 1, a gear set 402 is rotatably installed on the moving plate 2, and a housing is installed on the moving plate 2 to protect the outside of the camera 201 through the housing. One of the gears of the gear set 402 is rotatably installed on the housing, providing an installation position for the gear and also reducing the possibility of the gear affecting the lens of the camera 201;

[0050] One of the gears of the gear set 402 meshes with the rack 401, and a hinge rod 403 is hinged to the other gear. A sliding plate 404 is slidably installed on the moving plate 2. The free end of the hinge rod 403 is hinged to the sliding plate 404. The hinge rod 403 is eccentrically hinged to the gear in the gear set 402. The sliding plate 404, the hinge rod 403 and the gear form a crank-slider structure, so that when the gear rotates, it drives the position of the hinge rod 403 in the horizontal direction to change, and then the sliding plate 404 can reciprocate on the moving plate 2 by the pulling or pushing of the hinge rod 403;

[0051] Among them, a rod body is installed on the moving plate 2, a groove plate is installed on the rod body, a vertical rod is installed on the groove plate, and one side of the two ends of the static plate 4 is connected to the vertical rod. As Figure 7 shown, the static plate 4 is installed through the vertical rod, and the maximum movement limit of the scraping plate 5 only moves to the end of the static plate 4. Therefore, the influence of the vertical rod on the movement limit of the scraping plate 5 is reduced, and the feasibility of the device is increased;

[0052] A connecting spring 405 is installed on the sliding plate 404, and a connecting frame 406 is installed on the free end of the connecting spring 405. A friction roller 407 in contact with the electrostatic plate 4 is rotatably installed on the connecting frame 406. The scraper plate 5 is installed on the connecting frame 406 through a spring rope. The scraper plate 5 and the friction roller 407 are respectively located on both sides of the electrostatic plate 4. The scraper plate 5 is located on the side of the electrostatic plate 4 facing the camera 201, that is, the upper surface, and the friction roller 407 is located on the lower surface of the electrostatic plate 4. The two sandwich the electrostatic plate 4 in the middle so that they will not interfere with each other. The electrostatic plate 4 and the friction roller 407 are both made of plastic. Figure 1 From the main perspective, the axis of the connecting spring 405 is in the vertical direction. When the sliding plate 404 moves in the horizontal direction, the connecting frame 406 is driven to move in the horizontal direction, and then the friction roller 407 is driven to reciprocate in the horizontal direction. The relative displacement between the friction roller 407 and the electrostatic plate 4 is directly caused, so that static electricity is generated between the two by friction, so that the electrostatic plate 4 can maintain heterogeneous charges for a long time, which increases the feasibility of the device. When the sliding plate 404 moves to the lowest part of the arc of the electrostatic plate 4, the electrostatic plate 4 resists the friction roller 407 and the elastic deformation of the connecting spring 405, so that the lowest point of the electrostatic plate 4 will not block the movement of the friction roller 407 and the sliding plate 404, which increases the feasibility of the device. In this process, the scraper plate 5 is connected to the connecting frame 406 by a spring rope. When the connecting frame 406 moves downward, the elastic deformation of the spring rope enables the scraper plate 5 to still contact the upper surface of the electrostatic plate 4, which further increases the feasibility of the device.

[0053] When the device is in use, when the moving plate 2 moves on the hanging plate 1, the moving plate 2 and the hanging plate 1 move relative to each other, so that the rack 401 can drive the gear in the gear set 402 to rotate, and then the rotation of the gear drives the hinge rod 403 to change its position in the horizontal direction to push and pull the sliding plate 404, so that the sliding plate 404 can drive the friction roller 407 and the scraping plate 5 to reciprocate on the electrostatic plate 4. During the process, the scraping plate 5 scrapes the dust on the electrostatic plate 4, and the friction roller 407 rubs against the electrostatic plate 4, so that the heterogeneous charges on the electrostatic plate 4 are supplemented, which increases the practicality of the device.

[0054] The hanging plate 1 is not equipped with a rack 401 in the arc section, so the sliding plate 404 and the scraper plate 5 slide in sections. The length of the straight section of the hanging plate 1 is greater than the length of the arc section. Even if the scraper plate 5 does not move in the arc section, the dust accumulated on the electrostatic plate 4 will not reach the level that the scraper plate 5 cannot scrape, which increases the feasibility of the device.

[0055] Among them, Figure 2As shown in the figure, the hinge point of the hinge rod 403 and the pinion is set as point A. When the pinion rotates 180 degrees, it becomes point B. Then, an auxiliary line in the vertical direction is drawn with the center of the large gear as the center. The projections of the centers of the arcs of the static plate 4 and the center of the large gear housing installed on the moving plate 2 are both located on the auxiliary line. The centers of the pinion and the large gear are also located on the auxiliary line. It can be concluded that the projection of the midpoint of the static plate 4 is also located on the auxiliary line, resulting in the midpoint of the static plate 4 being located between point A and point B. And because the midpoint of the static plate 4 is located between point A and point B, when the pinion rotates 180 degrees, the position of the hinge rod 403 must be able to move to the other side of the static plate 4, increasing the feasibility of the device.

[0056] As Figure 3 , Figure 6 and Figure 10 shown in the figure, in the second embodiment, the moving plate 2 includes a moving part 202 and a mounting part 203. The camera 201 is mounted on the mounting part 203. A concentration box 7 is mounted on the moving part 202. The dust collection box 6 is mounted on the concentration box 7 through a connecting rod 8. A cavity for communicating the dust collection box 6 and the concentration box 7 is provided on the connecting rod 8. A fan 9 is rotatably mounted in the concentration box 7. A filter plate 10 is mounted above the fan 9 in the concentration box 7. The connecting rod 8 not only provides an installation position for the dust collection box 6 but also functions as a pipeline, enabling the interior of the dust collection box 6 to communicate with the interior of the concentration box 7, so that dust can enter the concentration box 7 through the connecting rod 8. Figure 1 Taking the main perspective, the axis of the connecting rod 8 is in the horizontal direction and perpendicular to the advancing direction of the moving plate 2, making it difficult for the dust to move outside the concentration box 7 again under the action of external forces after entering the concentration box 7.

[0057] The fan 9 is driven by a motor or other power source. The fan 9 is mounted at the bottom of the concentration box 7. A hole is provided at the bottom of the concentration box 7 for the air flow to enter and exit. When the device is in use, the fan 9 sucks air into the concentration box 7. Since the air pressure is low when the air flow velocity is fast, the air pressure in the concentration box 7 is less than the air pressure in the dust collection box 6, enabling the dust to enter the concentration box 7 through the cavity of the connecting rod 8. The filter plate 10 is located above the fan 9 to block the dust, reducing the possibility of the dust contacting the fan 9. The concentration box 7 further collects and stores the dust. The installation position of the connecting rod 8 reduces the possibility of the dust leaking out of the concentration box 7, thereby reducing the possibility of the dust being raised again and increasing the practicality of the device.

[0058] As Figure 4 , Figure 5 and Figure 8As shown, in the second embodiment, a mounting rod 11 is installed on the air guide tube 3, and the mounting rod 11 is connected to the mounting portion 203. An auxiliary rod 12 is also installed on the air guide tube 3, and an insertion rod 14 is slidably installed on the auxiliary rod 12 through a sliding spring 13. A surrounding frame 15 is installed on the moving portion 202, and an insertion hole 16 for accommodating the insertion rod 14 is opened on the surrounding frame 15 and the centralizing box 7. The inner wall of the surrounding frame 15 is used to fit tightly with the outer wall of the centralizing box 7, thereby increasing the contact area between the moving portion 202 and the centralizing box 7, so that the centralizing box 7 can be more stably installed on the moving portion 202. The mounting rod 11 and the auxiliary rod 12 are used to install the air guide tube 3 on the mounting portion 203. An opening is opened on the top of the centralizing box 7, through which the inside of the centralizing box 7 is connected with the outside, so that the inside of the centralizing box 7 is easy to clean.

[0059] The frame 15 is used to accommodate the centralized box 7. When the device is installed, the end of the centralized box 7 is inserted into the interior of the frame 15. During the process, the inner wall of the frame 15 is tightly fitted with the outer wall of the centralized box 7, and the centralized box 7 is preliminarily connected, which reduces the possibility of the centralized box 7 falling. The insertion rod 14 is pulled to slide it away from the frame 15. When the insertion hole 16 on the centralized box 7 is aligned with the insertion hole 16 on the frame 15, the insertion rod 14 is released, and the insertion rod 14 is pushed to be inserted into the insertion hole 16 by the reset of the sliding spring 13. The side wall of the insertion rod 14 blocks the inner wall of the insertion hole 16 to limit the tendency of the centralized box 7 to move away from the moving part 202, thereby increasing the stability of the centralized box 7 during use. After the device has been used for a period of time, the insertion rod 14 is slid to separate it from the insertion hole 16, the centralized box 7 and the moving part 202 are disassembled, and the inside of the centralized box 7 is cleaned through the opening thereon, thereby increasing the practicality of the device.

[0060] like Figure 9 and Figure 10 As shown, in the second embodiment, the centralized box 7 includes a housing shell 701 and a cover plate 702, a plug-in plate 703 is installed on the housing shell 701, a resisting rod 705 is slidably installed on the cover plate 702 through a resisting spring 704, and a resisting hole 706 for accommodating the resisting rod 705 is opened on the plug-in plate 703. When the centralized box 7 is connected to the moving part 202, the end of the resisting rod 705 resists the side wall of the mounting part 203. The centralized box 7 is U-shaped, and the cover plate 702 is also U-shaped. When the cover plate 702 is separated from the housing shell 701, the caliber of the opening on the centralized box 7 is increased, which further facilitates the cleaning of the centralized box 7. The cover plate 702 is made of plastic or other elastic materials;

[0061] When installing the centralized box 7, the cover plate 702 is installed on the receiving shell 701 by inserting. The abutting spring 704 forces the abutting rod 705 to move away from the U-shaped inner wall of the cover plate 702. When installing the cover plate 702, press the abutting rod 705 or bend the two ends parallel to the cover plate 702 to approach each other, so that the abutting rod 705 will not block the insertion plate 703 during the process of inserting the cover plate 702 into the receiving shell 701. When the abutting rod 705 moves to align with the abutting hole 706, the abutting rod 705 is inserted into the abutting hole 706, restricting the tendency of the cover plate 702 to move away from the receiving shell 701, enabling the normal use of the formed centralized box 7. However, when the centralized box 7 needs to be cleaned, pull the abutting rod 705 to separate it from the abutting hole 706, facilitating the upward extraction of the cover plate 702 to separate the cover plate 702 from the receiving shell 701, facilitating the cleaning of the centralized box 7;

[0062] After the centralized box 7 is connected to the moving part 202, the inside of the U-shaped cover plate 702 fits against the outer wall of the installation part 203. At this time, one end of the abutting rod 705 is located inside the centralized box 7, and external forces are not likely to affect it. The other end of the abutting rod 705 is abutted by the side wall of the installation part 203, restricting the sliding of the abutting rod 705. At this time, the installation part 203 functions as a limiting part, further increasing the stability of the abutting rod 705 during use and reducing the possibility of the cover plate 702 separating from the receiving shell 701 when the device is in use.

[0063] As Figure 11 shown, in the second embodiment, a rotating column 17 is installed on the installation part 203. One of the gears of the gear set 402 is rotatably connected to the rotating column 17. An oil storage cavity 1701 is formed on the rotating column 17. The rotating column 17 is also provided with an inlet for adding lubricating oil into the oil storage cavity 1701. A plug is inserted into the inlet, reducing the possibility of oil leakage during the use of the device and reducing the waste of lubricating oil;

[0064] An oil outlet 1702 is formed on the rotating column 17. A shielding shell 1704 that is slidably installed in the oil storage cavity 1701 and is inserted into the oil outlet 1702 is provided. A notch 1705 is formed on the shielding shell 1704. A return spring 1703 is installed between the oil storage cavity 1701 and the shielding shell 1704. The return spring 1703 forces the shielding shell 1704 to move towards the outside of the oil storage cavity 1701;

[0065] An oil passage 1706 is formed on the gear of the gear set 402 that is rotatably connected to the rotating column 17. When the inner diameter of the gear abuts against the shielding shell 1704, the notch 1705 is retracted into the oil outlet 1702. When the shielding shell 1704 communicates with the oil passage 1706, the notch 1705 communicates with the oil passage 1706;

[0066] The inner wall of the gear fits with the outer wall of the rotating column 17, so that the inner wall of the gear always presses the shielding shell 1704 into the oil outlet 1702, so that the gap 1705 is located at the oil outlet 1702, thereby preventing the lubricating oil in the oil storage chamber 1701 from moving to the outside of the oil storage chamber 1701. When the gear rotates, it drives the oil channel 1706 to make a circular motion around the axis of the rotating column 17. When the oil channel 1706 rotates to align with the oil outlet 1702, the inner wall of the gear releases the shielding shell. The shielding of 1704 causes the return spring 1703 to push the shielding shell 1704 to drive the notch 1705 to move to the outside of the oil storage chamber 1701, so that the lubricating oil can move into the oil passage 1706 through the notch 1705. When the gear continues to rotate, the inner wall of the oil passage 1706 resists the end of the shielding shell 1704, so that it is immersed in the oil storage chamber 1701 again, so that the lubricating oil intermittently enters the oil passage 1706, thereby increasing the utilization rate of the lubricating oil.

[0067] Among them, the oil outlet 1702 is facing a vertically downward position, so that when the lubricating oil enters the oil channel 1706, it can be affected by gravity and can move to the outside of the gear, and then through the meshing between the gears of the gear set 402, the meshing between the gear set 402 and the rack 401, the lubricating oil can lubricate the gear set 402 and the rack 401, thereby increasing the lubrication between the rack 401 and the gear set 402, allowing the gear to rotate more smoothly, thereby increasing the practicality of the device.

[0068] Embodiment 3

[0069] like Figure 1 - Figure 11 As shown, the third embodiment is further disclosed on the basis of the second embodiment. In the third embodiment, when the oil passage 1706 rotates to align with the oil outlet 1702, the inner wall of the gear releases the shielding shell 1704, so that the return spring 1703 pushes the shielding shell 1704 to drive the notch 1705 to move to the outside of the oil storage chamber 1701, so that the lubricating oil can move into the oil passage 1706 through the notch 1705. When the gear continues to rotate, the inner wall of the oil passage 1706 pushes the shielding shell 1704 to drive the notch 1705 to move to the outside of the oil storage chamber 1701. 04 end portion is resisted, so that it is immersed in the oil storage chamber 1701 again, so that the lubricating oil intermittently enters the oil channel 1706. During the process, since the end face of the shielding shell 1704 facing away from the oil storage chamber 1701 is an arc-shaped surface, when the inner wall of the oil channel 1706 resists the end of the shielding shell 1704, the shielding shell 1704 can be better pressed into the oil storage chamber 1701 through the guidance of its arc-shaped surface, which is similar to the telescopic protrusion structure on the handle of a folding umbrella, thereby increasing the feasibility of the device.

[0070] In the third embodiment, a plurality of extension rods 18 are installed on the installation part 203. The insertion rods 14 are also slidably installed on the extension rods 18 through sliding springs 13. Insertion holes 16 with the same number as the insertion rods 14 are also formed on the centralized box 7, the installation part 203 and the moving part 202. An extension plate 19 is installed on the insertion rod 14, and a unified rod 20 is installed between adjacent extension plates 19. By installing the insertion rods 14 on the plurality of extension rods 18 on the installation part 203, the contact sites between the installation part 203 and the moving part 202 and between the centralized box 7 are increased, thereby further increasing the stability of the centralized box 7 during the use of the device. When it is necessary to disassemble the centralized box 7, by pulling the unified rod 20, the insertion rods 14 connected to the unified rod 20 are simultaneously separated from the insertion holes 16. While enhancing the installation strength of the centralized box 7, the unified rod 20 also facilitates the separation of the insertion rods 14 from the insertion holes 16, making the disassembly of the centralized box 7 not overly complicated and increasing the practicality of the device.

[0071] In the third embodiment, a vertical groove 21 is formed on the cover plate 702, and a vertical block 22 for slidably inserting into the vertical groove 21 is installed on the receiving shell 701. The vertical groove 21 penetrates the cover plate 702 in the vertical direction. When the cover plate 702 is installed, the vertical groove 21 and the vertical block 22 are aligned, and then the cover plate 702 is inserted. During use, the contact area between the cover plate 702 and the receiving shell 701 is increased, thereby increasing the stability of the cover plate 702 on the receiving shell 701. Moreover, by the vertical block 22 blocking the inner wall of the vertical groove 21, the tendency of the two parallel sections of the cover plate 702 to approach each other is restricted, thereby reducing the possibility of the cover plate 702 separating from the receiving shell 701 and increasing the stability of the centralized box 7 during use.

[0072] In the third embodiment, a guiding groove 23 is formed on the installation part 203, and a guiding block 24 slidably engaged with the guiding groove 23 is installed on the sliding plate 404. The guiding groove 23 is formed in the horizontal direction, and the guiding block 24 is blocked by the inner wall of the guiding groove 23, so that the guiding block 24 can only slide in the horizontal direction, thereby restricting the sliding direction of the sliding plate 404 and increasing the stability of the sliding plate 404 during sliding.
