Description

Technical Field

[0001] This utility model relates to the field of wall heavy metal detection technology, specifically a wall heavy metal detection swab. Background Technology

[0002] The construction and decoration of houses require the use of a large amount of paint and waterproof coatings. During actual use, these coatings, including those inside the building itself, may contain high levels of heavy metals. Therefore, for health reasons, it is necessary to test the walls for heavy metals.

[0003] When testing for heavy metals in soil, users need to place the probe on the ground. However, sometimes the soil heavy metal detector cannot penetrate deep into the soil to detect heavy metals quickly and effectively. Furthermore, prolonged use can cause the soil heavy metal detector probe to become contaminated with debris and soil, thereby reducing the accuracy and efficiency of subsequent tests.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN114062655B, publication date: 2024-03-29) discloses a soil heavy metal pollution detection device, belonging to the field of soil testing. This soil heavy metal pollution detection device includes an outer shell, a pair of main support components, a drilling component, a pair of auxiliary support components, a detection component, a pair of soil heavy metal detectors, a soil removal component, and a propulsion component. The outer shell is detachably connected, and a receiving cavity is formed between the outer shells. During soil testing, the device allows the drill bit to penetrate the soil to loosen the soil layer beforehand, enabling the soil heavy metal detector to penetrate deep into the ground for in-depth heavy metal detection. The soil heavy metal detector's probe surface does not directly contact the hard soil clods due to the double barrier of the observation window and the opening on the soil-blocking ring, as well as the rotation of the outer detection sleeve pushing away soil clods, thus preventing damage to the soil heavy metal detector.

[0005] While the above design can solve the aforementioned problems, it is not convenient enough when the swab needs to be removed in time to complete the testing operation. This makes the swab testing work easily affected, reducing the stability and accuracy of the equipment. At the same time, when conducting wall testing, the hard wall material makes direct contact with the wall less accurate, affecting the final test accuracy. Utility Model Content

[0006] The purpose of this utility model is to provide a wall heavy metal detection swab to solve the problem mentioned in the background art, which is not convenient enough when the swab needs to be pulled out in time to complete the detection operation, making the swab detection work easily affected and reducing the stability and accuracy of the equipment. At the same time, when conducting wall detection, the hard wall material makes direct contact with the wall less accurate, affecting the accuracy of the final detection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wall heavy metal detection swab, including a metal detection swab, a support frame is installed on the outside of the metal detection swab, and a quick-adjustment drive adjustment mechanism is provided between the support frame and the metal detection swab.

[0008] Furthermore, the drive adjustment mechanism includes an extended transmission rod and a drive rotary motor, and an elastic sliding mechanism for moving the rotating buffer rod up and down is installed inside the vertical sliding frame. The drive adjustment mechanism includes a drive rotary motor, which is fixedly installed on the upper surface of the support and bonding frame. A friction transmission rod is installed on the outer surface of the output end of the rotating cleaning rod, and a series transmission belt is installed on the outer surface of the friction transmission rod.

[0009] Furthermore, the rotating cleaning rod is rotatably installed inside the rotating stabilizing frame, and an integrated fixed gear is installed on the back of the rotating stabilizing frame. Connecting meshing worm gears are installed on the left and right sides of the supporting fitting frame, and the connecting meshing worm gears mesh with the integrated fixed gear.

[0010] Furthermore, the upper and lower sides of the extended transmission rod slide along the interior of the limiting sliding groove, and an L-shaped connecting rod is installed on the outer surface of the end of the extended transmission rod. A rotating buffer rod is installed at the end of the L-shaped connecting rod, and the end of the rotating buffer rod slides vertically along the interior of the vertical sliding frame. The elastic sliding mechanism includes the extended transmission rod, which is slidably installed inside the support bonding frame. A metal detection swab is installed at the front end of the extended transmission rod, and limiting sliding grooves are opened on the upper and lower sides of the support bonding frame.

[0011] Furthermore, the top of the rotating buffer rod is rotatably mounted inside the end of the L-shaped connecting rod, and a compression spring is installed on the outer surface of the support fitting frame. The other end of the compression spring is fixedly mounted on the inner surface of the rotating buffer rod. The L-shaped connecting rod, the rotating buffer rod, the vertical sliding frame, and the compression spring are symmetrically installed in two sets about the center point of the support fitting frame. Rotational stabilizing frames are installed on the left and right sides of the support fitting frame, and a meshing transmission mechanism for rotating the rotating cleaning rod is installed inside the rotational stabilizing frame.

[0012] Furthermore, the extended transmission rod and the metal detection swab are designed as a single unit, and the extended transmission rod slides along the inside of the limiting sliding groove. The outer surface of the rotating buffer rod contacts the inner surface of the vertical sliding frame to form a sliding structure, and the inner surface of the rotating buffer rod contacts the top of the compression spring to form an elastic structure.

[0013] Furthermore, the interior of the series transmission belt is in contact with the top outer surface of the connecting meshing worm gear, and the front end of the rotating cleaning rod corresponds to the front end of the metal detection swab. The outer surface of the connecting meshing worm gear contacts the outer surface of the integral fixed gear to form a meshing structure, and the friction transmission rod contacts the top of the integral fixed gear through the interior of the series transmission belt to form a transmission structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the wall heavy metal detection swab needs to be attached to the wall, the extension transmission rod is pushed directly along the limiting sliding inner groove to make the metal detection swab contact the wall. After the measurement is completed, when the extension transmission rod is no longer under force, the compression spring will reset the metal detection swab through the L-shaped connecting rod and the rotating buffer rod. This design makes the reset faster when the detection operation is completed, and the swab can be moved more quickly, improving the efficiency of use and the accuracy of the swab detection results. In addition, the front end of the swab is replaceable, which reduces the cost of using the swab.

[0015] Furthermore, when more precise wall inspection is required, the drive motor can be directly started to drive the rotating cleaning rod and the connecting transmission belt to drive the connecting worm gear. At this time, the connecting worm gear rotates the rotating cleaning rod by meshing with the integrated fixed gear. The powder generated by the rotation of the rotating cleaning rod will be detected by the metal detection swab. This design makes the test results more accurate and improves the final detection accuracy.

[0016] Furthermore, the limiting sliding groove will keep the upper and lower sides of the extension transmission rod stable and limit their movement, making the equipment more stable in use. At the same time, the mutual rotation of the L-shaped connecting rod and the rotating buffer rod will make the equipment more precise in use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 The present invention provides the following technical solution: a wall heavy metal detection swab, including a metal detection swab 9, and a support frame 1 installed on the outside of the metal detection swab 9, characterized in that: a quick-adjustment drive adjustment mechanism is provided between the support frame 1 and the metal detection swab 9.

[0026] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem that the design is not convenient enough when the swab needs to be removed promptly to complete the testing operation, which easily affects the swab testing work and reduces the stability and accuracy of the equipment. The solution discloses that: the upper and lower sides of the extension transmission rod 3 slide along the interior of the limiting sliding groove 2, and an L-shaped connecting rod 4 is installed on the outer surface of the end of the extension transmission rod 3. A rotating buffer rod 5 is installed at the end of the L-shaped connecting rod 4, and the end of the rotating buffer rod 5 slides vertically along the interior of the vertical sliding frame 6. The top of the rotating buffer rod 5 is rotatably installed inside the end of the L-shaped connecting rod 4. Figure 4As shown, a compression spring 7 is installed on the outer surface of the support frame 1. The other end of the compression spring 7 is fixedly installed on the inner surface of the rotating buffer rod 5. The L-shaped connecting rod 4, the rotating buffer rod 5, the vertical sliding frame 6 and the compression spring 7 are symmetrically installed in two sets about the center point of the support frame 1. The extension transmission rod 3 and the metal detection swab 9 are integrated into one piece. The extension transmission rod 3 slides along the inside of the limiting sliding groove 2. The outer surface of the rotating buffer rod 5 contacts the inner surface of the vertical sliding frame 6 to form a sliding structure. The inner surface of the rotating buffer rod 5 contacts the top of the compression spring 7 to form an elastic structure.

[0027] When it is necessary to attach the metal detection swab 9 to the wall for detection, the extension transmission rod 3 is pushed forward along the inside of the support frame 1. This causes the extension transmission rod 3 to slide within the limiting sliding grooves 2 on both the upper and lower sides of the support frame 1. The movement of the extension transmission rod 3 synchronously drives the metal detection swab 9, which is fixedly installed at its end. As the metal detection swab 9 moves, it comes into contact with the outside of the wall and begins metal detection. During the movement of the extension transmission rod 3, the L-shaped connecting rod 4, which is fixedly installed on the outer surface of its end, is driven to move synchronously. The rotating buffer rod 5, which is rotatably installed inside the end of the L-shaped connecting rod 4, also moves synchronously. Due to the compression of the end of the rotating buffer rod 5, such as... Figure 4 As shown, at this time, the rotating buffer rod 5 will slide within the vertical sliding frame 6 fixedly installed on the outer surface of the support frame 1. As the vertical sliding frame 6 slides outward, the compression spring 7 fixedly installed on the inner surface of the vertical sliding frame 6 will correspondingly produce an extension and elongation effect.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6The technical solution shown addresses the problem that direct contact with hard wall materials during wall inspection can lead to inaccurate test results, affecting the final inspection accuracy. It discloses the following: a rotating cleaning rod 11 is rotatably mounted inside a rotating stabilizing frame 8, with an integrated fixed gear 13 mounted on the back of the stabilizing frame 8. Connecting worm gears 12 are mounted on the left and right sides of the supporting frame 1, meshing with the integrated fixed gear 13. The upper and lower sides of the extending transmission rod 3 slide within the limiting sliding groove 2, and an L-shaped connecting rod 4 is mounted on the outer surface of the end of the extending transmission rod 3. A rotating buffer rod 5 is mounted at the end of the L-shaped connecting rod 4, and the end of the rotating buffer rod 5 slides vertically within the vertical sliding frame 6. The sliding mechanism includes an extension transmission rod 3, which is slidably installed inside the support frame 1. A metal detection swab 9 is installed at the front end of the extension transmission rod 3. Limiting sliding grooves 2 are formed on the upper and lower sides of the support frame 1. The top of the rotating buffer rod 5 is rotatably installed inside the end of the L-shaped connecting rod 4. A compression spring 7 is installed on the outer surface of the support frame 1, and the other end of the compression spring 7 is fixedly installed on the inner surface of the rotating buffer rod 5. Two sets of L-shaped connecting rods 4, rotating buffer rods 5, vertical sliding frames 6, and compression springs 7 are symmetrically installed about the center point of the support frame 1. Rotational stabilizing frames 8 are installed on the left and right sides of the support frame 1, and a meshing transmission mechanism for rotating the rotating cleaning rod 11 is installed inside the rotational stabilizing frames 8.

[0029] When more efficient and accurate testing results are required, the drive rotary motor 10, fixedly mounted on the upper surface of the support bonding frame 1, is directly started. At this time, the friction transmission rod 14, fixedly mounted on the outer surface of the output end of the drive rotary motor 10, is driven to perform stable circumferential rotation. The rotation of the friction transmission rod 14 synchronously drives the series transmission belt 15, which is mounted on the outer surface and is in contact with each other. As the series transmission belt 15 rotates, the two sets of connecting meshing worm gears 12, which are also in contact with each other at both ends inside the series transmission belt 15, are synchronously driven, causing the connecting meshing worm gears 12 to continuously rotate vertically along the left and right sides of the support bonding frame 1. During the rotation of the support bonding frame 1, the integral fixed gear 13, which is in contact with the outer surface, engages and is driven by it. Figure 6 As shown, the integrated fixed gear 13 will rotate stably in a circular motion due to the meshing motion. Since the integrated fixed gear 13 is fixedly installed at the end of the rotating cleaning rod 11, the rotating cleaning rod 11 will be driven to rotate stably along the inside of the rotating stabilizing frame 8 fixedly installed on the inner surface of the support and bonding frame 1. At the same time, the rotation of the rotating cleaning rod 11 will adhere to the outside of the wall, causing the dust outside the wall to fall off and fly away, ensuring that the detection effect of the metal detection swab 9 is more accurate.

[0030] Example 3: When no force is applied to the extension transmission rod 3, the compression spring 7 will contract rapidly due to its own elastic potential energy, producing a slight "click" sound. This process is accompanied by a vibration. By rotating the buffer rod 5 and the L-shaped connecting rod 4, the extension transmission rod 3 can be smoothly reset. This design not only ensures more stable use of the equipment, but also improves the smoothness and comfort of operation, allowing users to experience delicate mechanical feedback and reliable performance during use.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
