Abstract
Description
Technical Field
[0001] This utility model relates to the field of sharp point testing instruments, and more specifically, to an inspection module and inspection system for a sharp point testing instrument. Background Technology
[0002] A sharp point tester is a device used to detect the presence of potentially dangerous sharp points in accessible areas of toys. The device is designed according to multiple international and domestic standards, such as GB 6675.2-2014 Toy Safety Part 2: Mechanical and Physical Properties. The tester typically includes a measuring slot, measuring cover, sensor head, locking ring, battery, and indicator light. The testing method involves placing the sharp point tester on an accessible sharp point, inserting the point into the measuring slot, and checking if the point can penetrate to the specified depth. When the insertion depth exceeds the specified depth, the point compresses the sensor head, causing it to move and contact the battery, forming a closed circuit. The indicator light on the top of the tester will illuminate, indicating that the point is sharp. Conversely, when the insertion depth is less than the specified depth, the indicator light will not illuminate, indicating that the point is acceptable. In practical use, the depth of the measuring slot is typically 0.38 mm, and the critical value for the standard height of the point is 0.50 mm; that is, points below 0.50 mm are considered acceptable.
[0003] When calibrating the illumination depth of a sharp point tester, it is usually necessary to loosen the locking ring, rotate the measuring cover to the target scale according to the calibration reference mark, and adjust the distance between the sensor head and the battery to the specified value to bring the tester to a standard state. This specified value is usually 0.12mm, resulting in an illumination depth of 0.50mm. Because the calibration values are quite precise, the sharp point tester usually needs to be sent to a relevant institution for calibration before being returned to the place of use. Even self-calibration is time-consuming. Generally, a sharp point tester can have a long service life after one calibration. However, due to repeated use or malfunctions of components such as springs, the illumination depth may be significantly affected. In actual toy production, the detection of toy sharp points involves a large workload, and performing precise calibration before each test would greatly impact production efficiency. Therefore, researching a detection device to efficiently detect whether the illumination depth of a sharp point tester has a large error, and to promptly recalibrate the illumination depth of the sharp point tester, has significant practical value. Utility Model Content
[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide an inspection module and inspection system for a sharp tip tester, which facilitates the detection of the illumination depth status of the tip tester.
[0005] One objective of this utility model is to provide an inspection module for a sharp tip tester, including a base, on which at least a first inspection post, a second inspection post, and a third inspection post are fixedly connected, wherein the first inspection post, the second inspection post, and the third inspection post are all vertically connected to the base and their heights increase sequentially.
[0006] The first and second inspection posts are configured such that, when the sharp tip tester is in its standard state, neither the first nor the second inspection post illuminates, and the height difference between the first and second inspection posts is 0.02 mm to 0.50 mm. Preferably, the height difference between the first and second inspection posts is 0.10 to 0.30 mm.
[0007] In this technical solution, the heights of the first, second, and third inspection posts are all numerical values based on the base surface. The first, second, and third inspection posts are designed to mimic a sharp point. During testing, the testing instrument needs to be inserted along the direction of the strongest rigidity of the sharp point. Therefore, the inspection posts are set perpendicular to the base. During debugging, the testing instrument only needs to be inserted into the inspection post in a vertical direction, which facilitates debugging and improves the accuracy of debugging.
[0008] The sharp tip tester being in standard condition can be understood as follows: the distance between the tester's sensor head and the battery is at a specified value, and the tester is also at a specified lighting depth, such as 0.50mm as specified in the standard. The specified lighting depth here should include the allowable error range.
[0009] When the tester does not illuminate when testing the first inspection post but illuminates when testing the second inspection post, it indicates that the illumination depth of the tester is between the heights of the first and second inspection posts. This confirms that the illumination depth is within the range of the height difference between the two inspection posts. Combined with the small height difference between these two posts, this means that the illumination depth of the tester does not have a significant error, and recalibration is unnecessary. Conversely, if the tester illuminates when testing the first inspection post, it indicates that the illumination depth is less than or equal to the height of that inspection post, meaning there is a significant error in the illumination depth. Recalibration is required, and the adjustment should be made towards the larger value. This provides a valuable reference for the calibration process. Similarly, if the tester does not illuminate when testing the second inspection post, it indicates that the illumination depth is greater than the height of that inspection post, also indicating a significant error in the illumination depth. Recalibration is required, and the adjustment should be made towards the smaller value. This also provides a valuable reference for the calibration process.
[0010] This solution directly detects whether there are significant errors in the illumination depth of the tester by checking the illumination status. It is highly efficient and convenient, ensuring the reliability of toy tip detection results during production. Furthermore, this solution provides adjustment references for calibration work, improving the efficiency of calibration processes.
[0011] Furthermore, if the second inspection column does not light up, the illumination depth of the tester needs to be reduced. In this case, the test can be performed on the third inspection column. If the third inspection column lights up, the illumination depth should be less than or equal to that of the third inspection column. Only minor adjustments to the tester are needed. Conversely, a larger adjustment is required. This further facilitates the calibration process.
[0012] Furthermore, the height of the first inspection column is 0.30–0.45 mm, the height of the second inspection column is 0.55–0.70 mm, and the height of the third inspection column is 0.80–1.00 mm.
[0013] In practice, the standard illumination depth of a sharp tip tester is usually 0.50mm. The inspection column height setting in this application is suitable for common debugging, thus improving applicability and practicality.
[0014] Furthermore, the heights of the first inspection post, the second inspection post, and the third inspection post increase arithmetically.
[0015] Furthermore, the base is provided with fixing holes, and the first inspection post, the second inspection post and the third inspection post are respectively embedded in the corresponding matching fixing holes.
[0016] In this technical solution, compared to the test column being directly connected to the surface of the base, the embedded connection method can improve the stability and firmness of the connection between the test column and the base, extend its service life, and also ensure the accuracy of the test results.
[0017] Furthermore, the base, the first inspection post, the second inspection post, and the third inspection post are all made of stainless steel.
[0018] Another objective of this invention is to provide an inspection system comprising a fixed bracket, a limiting component, a sharp tip tester, and an inspection module of any of the above, wherein the fixed bracket comprises a vertical rod and a horizontal rod connected to the top of the vertical rod.
[0019] The limiting component includes a suspension frame, the sharp tip tester is detachably vertically connected to the suspension frame, the suspension frame is suspended from the horizontal bar and movably connected to it in the vertical direction, and the inspection module is located below the sharp tip tester.
[0020] Traditional testing methods typically involve hand-holding the tester to assess the pointed tip. This handheld approach can lead to instability and instrument displacement, making it difficult to ensure the tester is dropped vertically into the tip, thus affecting test results. This solution addresses this by vertically connecting the suspension frame to the horizontal bar, and the tester to the suspension frame, thereby vertically limiting the tester's movement. This facilitates vertical dropping of the tester, reduces operational difficulty, and improves the accuracy of test results.
[0021] Furthermore, a suspension rod is connected to the top of the suspension frame, the horizontal rod has a through hole, the suspension rod passes through the through hole and is movably connected to the horizontal rod, and a counterweight is connected to the top of the suspension rod.
[0022] In this technical solution, the counterweight can apply a downward force to the tester. Its weight is set according to actual needs, preferably providing a force of 4.5N. Compared with hand-held control of the force, the counterweight improves the accuracy of the applied force, thereby improving the reliability of the test results.
[0023] Furthermore, a bearing sleeve is provided on the inner wall of the perforation.
[0024] Furthermore, the suspension frame includes a top plate, a bottom plate, and a connecting rod connecting the top plate and the bottom plate. The top plate is connected to the suspension rod, and the sharp tip tester is detachably and vertically connected to the bottom plate.
[0025] Furthermore, a base is connected to the bottom of the vertical rod of the fixed bracket, and the inspection module is placed on the base.
[0026] In this technical solution, the base can prevent unevenness of the debugging desktop from interfering with the debugging results. Therefore, the base can improve the adaptability of the inspection system.
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] (1) The setup of this scheme directly detects whether there is a large error in the lighting depth of the tester by checking the lighting status. It is efficient and convenient, which ensures the reliability of the test results of the toy's sharp points during production. At the same time, this scheme also provides an adjustment reference for calibration work, which improves the efficiency of calibration work.
[0029] (2) When the second inspection column does not light up, the lighting depth of the tester needs to be reduced. At this time, the test can be performed on the third inspection column. If the third inspection column lights up, the lighting depth is less than or equal to that of the third inspection column. Only a fine adjustment of the tester is needed. Otherwise, a larger adjustment is needed. This further facilitates the calibration work.
[0030] (3) By checking the setting of the fixed bracket and limit components of the system, the tester is vertically limited, which makes it easier to operate the tester to fall vertically, reduces the difficulty of operation, and improves the accuracy of the test results. At the same time, by setting the counterweight, the tester is precisely force-applied, which further improves the accuracy of the debugging results, thereby improving the reliability of the test results.

Detailed Implementation
[0039] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0040] Example 1
[0041] Combination Figures 1-6This embodiment provides an inspection module for a sharp tip tester 200, including a base 100. At least a first inspection post 110, a second inspection post 120, and a third inspection post 130 are fixedly connected to the base 100. The first inspection post 110, the second inspection post 120, and the third inspection post 130 are all vertically connected to the base 100 and their heights increase sequentially.
[0042] The first inspection post 110 and the second inspection post 120 are configured such that, when the sharp tip tester 200 is in its standard state, the first inspection post 110 does not light up, and the second inspection post 120 does not light up. The height difference between the first and second inspection posts is 0.02mm to 0.50mm, for example, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.10mm, 0.20mm, 0.30mm, or 0.40mm. The heights of the first inspection post 110, the second inspection post 120, and the third inspection post 130 increase arithmetically.
[0043] The height of the first inspection post 110 is 0.30–0.45 mm, the height of the second inspection post 120 is 0.55–0.70 mm, and the height of the third inspection post 130 is 0.80–1.00 mm. Preferably, the illumination depth of the tester is the median of the heights of the first inspection post 110 and the second inspection post 120, which can further reduce debugging errors and improve the accuracy of the tester.
[0044] The tip tester includes a measuring slot 210, a sensor head 220, a battery 230, an indicator light 240, and other structures. The measuring slot 210 has a depth of 0.38 mm and a square opening with dimensions of 1.02 × 1.15 mm. The distance between the sensor head 220 and the battery 230 is 0.12 mm at the standard illumination depth, i.e., the illumination depth is 0.50 mm. Figure 2 As shown in the diagram, when the height of the tip is less than the depth of the light, the indicator light 240 on the tester will not light up; Figure 3 As shown, when the height of the tip is greater than the depth of the light, indicator light 240 on the tester illuminates.
[0045] In this embodiment, the height of the first inspection column 110 is 0.40 mm, the height of the second inspection column 120 is 0.60 mm, and the height of the third inspection column 130 is 0.80 mm. The specified illumination depth of the tester is 0.50 mm. When checking the illumination depth, if the first inspection column 110 does not illuminate while the second inspection column 120 does, the instruction manual indicates that the illumination depth of the tester is between 0.40 and 0.60 mm, which is within the standard illumination state, or the error from the standard illumination depth is only within the allowable range, and it can continue to be used without recalibration. However, when the first inspection column 110 illuminates, the illumination depth of the tester is less than or equal to 0.40 mm, requiring recalibration, and the adjustment should be made towards the larger value. Similarly, when the tester does not illuminate the second inspection column 120, it indicates that the illumination depth of the tester is greater than 0.60 mm, requiring recalibration, and the adjustment should be made towards the smaller value. Furthermore, if neither the second inspection column 120 nor the third inspection column 130 lights up when tested, the instruction manual indicates that the lighting depth of the tester is greater than 0.80mm, and the calibration requires a significant reduction in the lighting depth.
[0046] Furthermore, the base 100 and the inspection column can be connected integrally, or the base 100 can be provided with fixing holes, and the first inspection column 110, the second inspection column 120, and the third inspection column 130 can be respectively embedded in the corresponding matching fixing holes. Compared with the inspection column being directly connected to the surface of the base 100, the embedded connection method can improve the stability and firmness of the connection between the inspection column and the base 100, extend its service life, and also ensure the accuracy of the test results.
[0047] The base 100, the first inspection post 110, the second inspection post 120, and the third inspection post 130 are all made of stainless steel. Compared to materials such as plastic, the stainless steel base 100 has a certain weight, which can prevent displacement of the base 100 during debugging and improve stability. The base 100 is rectangular, with a length of 6cm, a width of 3cm, and a height of 1cm. All the inspection posts are cylindrical with a cross-sectional diameter of 0.95mm. The first inspection post 110, the second inspection post 120, and the third inspection post 130 are arranged linearly.
[0048] Example 2
[0049] This embodiment provides an inspection module for a sharp tip tester 200, which has a similar structure to that of Embodiment 1, except that: in this embodiment, the height of the first inspection post 110 is 0.40mm, the height of the second inspection post 120 is 0.70mm, and the height of the third inspection post 130 is 1.00mm.
[0050] Example 3
[0051] like Figure 7 As shown, this embodiment provides an inspection system for a sharp tip tester 200, including a fixed bracket, a limiting component, a sharp tip tester 200, and the inspection module provided in Embodiment 1. The fixed bracket includes a vertical rod 310 and a horizontal rod 320 connected to the top of the vertical rod 310.
[0052] The limiting component includes a suspension bracket 420, and the sharp tip tester 200 is detachably vertically connected to the suspension bracket 420. The suspension bracket 420 is suspended from the horizontal bar 320 and is movably connected to it in the vertical direction. The inspection module is located below the sharp tip tester 200.
[0053] Traditional testing methods typically involve hand-holding the tester to evaluate the pointed tip. This handheld approach can lead to instability and instrument displacement, making it difficult to ensure the tester is dropped vertically into the pointed tip, thus affecting test results. This solution addresses this by vertically connecting the suspension bracket 420 to the horizontal bar 320, and also vertically connecting the tester to the suspension bracket 420. This vertically limits the tester's movement, facilitating a smooth vertical drop, reducing operational difficulty, and improving the accuracy of test results.
[0054] Furthermore, a suspension rod 410 is connected to the top of the suspension frame 420, and the horizontal rod 320 has a through hole, the inner wall of which is provided with a bearing sleeve 321. The suspension rod 410 passes through the through hole and is movably connected to the horizontal rod 320, and a counterweight 411 is connected to the top of the suspension rod 410.
[0055] The weight of the counterweight 411 is set according to actual needs, preferably providing a force of 4.5N. Compared with hand-held control of force, the setting of the counterweight 411 improves the accuracy of force application, thereby improving the reliability of test results.
[0056] Furthermore, the suspension bracket 420 includes a top plate 421, a bottom plate 422, and a connecting rod 423 connecting the top plate 421 and the bottom plate 422. The top plate 421 connects to the suspension rod 410, and the sharp tip tester 200 is detachably and vertically connected to the bottom plate 422. The sharp tip tester 200 can be connected to the bottom plate 422 in various ways, as long as a detachable connection and fixation can be achieved. Connection methods include, but are not limited to, abutting screws passing through the side of the bottom plate 422 and abutting against the tester, and being fixed by nuts.
[0057] Furthermore, a base 330 is connected to the bottom of the vertical rod 310 of the fixed bracket, and the inspection module is placed on the base 330. The base 330 can prevent unevenness of the debugging desktop from interfering with the debugging results; therefore, the base 330 can improve the adaptability of the inspection system.
[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
