Abstract
Description
Technical Field
[0001] This utility model relates to the field of mounting hole detection technology, specifically an adjustable refrigerator upper shelf mounting hole detection device. Background Technology
[0002] After the refrigerator's upper shelf is manufactured, mounting holes are left on it for easy installation. Once the upper shelf is finished, in order to ensure that subsequent shelves can be installed normally, it is usually necessary to check the position and depth of the mounting holes.
[0003] When the mounting holes are positioned accurately, their depth directly affects the installation quality: insufficient depth may result in insecure installation; excessive depth may waste materials or increase installation difficulty.
[0004] Currently, hole depth inspection methods include manual or mechanical inspection. Automated inspection on production lines typically employs machine vision-based automated optical inspection, using industrial cameras to acquire images of the mounting holes. After preprocessing and feature extraction, the results are judged. However, this method requires qualified personnel with specialized knowledge to adjust the industrial camera parameters according to the mounting hole specifications. Furthermore, external light sources can cause the edges of the mounting holes to become unclear during inspection, leading to blurred images captured by the industrial camera and ultimately resulting in errors in the judgment, thus affecting the final product quality. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable refrigerator upper shelf mounting hole detection device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An adjustable refrigerator shelf mounting hole detection device includes: a detection box, in which a support platform and a vertical plate are fixedly installed, and the support platform is used to place the shelf;
[0008] A shelf is slidably mounted on the support platform, and a depth measuring component is mounted on the shelf. The depth measuring component includes a fixed cylinder fixedly mounted on the shelf, and a depth measuring structure is mounted inside the fixed cylinder. During the descent of the shelf, the depth measuring structure can be inserted into the mounting hole on the partition, and the length of the depth measuring structure can be adjusted according to the appropriate depth of the mounting hole.
[0009] The fixed cylinder is equipped with a positioning component. During the descent of the depth measuring structure, the depth measuring structure can drive the positioning component to move according to the depth of the mounting hole. When the depth of the mounting hole is appropriate or insufficient, the positioning component can lock the position of the depth measuring structure. When the depth of the mounting hole is insufficient, the depth measuring structure can simultaneously turn on the signal light installed inside the fixed cylinder.
[0010] The adjustable refrigerator upper shelf mounting hole detection device as described above: the depth measuring structure includes a trigger rod slidably disposed in the fixed cylinder, a sleeve ring fixedly disposed on the trigger rod, a second protrusion formed on the outer wall of the sleeve ring, and the second protrusion slidably disposed in a through groove opened on the fixed cylinder.
[0011] The adjustable refrigerator upper shelf mounting hole detection device described above: the depth measuring structure further includes a plug-in cylinder coaxially fixedly arranged with the trigger rod, and a plug rod is slidably arranged inside the plug-in cylinder, and the plug rod is threadedly connected to a rotating cylinder rotatably mounted on the plug-in cylinder.
[0012] The adjustable refrigerator upper shelf mounting hole detection device described above: the positioning component includes a rotating sleeve rotatably mounted on the fixed cylinder, the inner wall of the rotating sleeve is provided with a composite groove, the second protrusion is slidably disposed in the composite groove, during the descent of the shelf, the second protrusion cooperates with the composite groove, which can drive the rotating sleeve to rotate and position the trigger rod.
[0013] The adjustable refrigerator upper shelf mounting hole detection device described above: the composite groove includes a spiral groove formed on the inner wall of the rotating sleeve, one end of the spiral groove is connected to a vertical groove, and the other end is connected to a buffer groove.
[0014] The adjustable refrigerator upper shelf mounting hole detection device described above: the rotating sleeve is further provided with an unlocking structure, the unlocking structure includes a piston cylinder fixedly mounted on the fixed cylinder, a piston rod slidably mounted inside the piston cylinder, the piston rod being fixedly connected to a sleeve sleeve mounted on the rotating sleeve, and a first protrusion being formed on the inner wall of the sleeve sleeve, the first protrusion being slidably mounted in a rotating groove opened on the outer wall of the rotating sleeve.
[0015] The adjustable refrigerator shelf mounting hole detection device described above: the unlocking structure further includes a trigger, the trigger including a fixed plate fixedly mounted on the upright plate, and an abutment rod fixedly mounted on the fixed plate. During the rising of the shelf, the abutment rod can force the piston rod to slide relative to the piston cylinder.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] By setting up multiple sets of depth measuring components and using the shelf to drive the multiple sets of depth measuring components to move synchronously, the depth of the mounting holes on the upper shelf of the refrigerator can be detected at one time, thereby improving the detection efficiency.
[0018] Meanwhile, by utilizing the depth measuring structure within the depth measuring component, the extension length of the insertion rod can be adjusted by rotating the rotating cylinder, and the required qualified depth of the mounting hole can be set, enabling the device to flexibly adapt to the depth detection of mounting holes with different depth specifications.
[0019] During the depth measurement process, the probe rod, rotating sleeve, and composite groove work together to lock the position of the depth measurement structure when the hole depth is acceptable, and the indicator light remains off. When the hole depth is shallow, the depth measurement structure is locked, and the indicator light is triggered to illuminate, allowing inspectors to locate unacceptable holes. When the hole depth is deep, the depth measurement structure will not be locked during the reset process, and the probe rod will automatically return to its initial position. For probe rods that are lower than the corresponding positions of acceptable and shallow installation holes, inspectors can identify unacceptable holes by observing the difference in probe rod position.
[0020] The entire test result is intuitive and unaffected by external light sources, making it easy for inspectors to mark non-conforming products. The test results are highly effective and accurate, and the operation is simple, while reducing manual labor intensity and human error. Attached Figure Description

Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.
[0033] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.
[0034] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0035] Please see Figures 1-10 In this embodiment of the present invention, an adjustable refrigerator upper shelf mounting hole detection device includes:
[0036] The testing box 1 is equipped with a support platform 2 and a vertical plate 3, and the support platform 2 is used to place the partition.
[0037] A shelf 4 is slidably mounted on the support platform 2, and a depth measuring component is mounted on the shelf 4. For details, please refer to [link to relevant documentation]. Figure 3 , Figure 4 The support platform 2 is provided with a lifting plate 301, which is controlled by a lifting mechanism (not shown in the figure) provided on the upright plate 3, and can drive the storage plate 4 to move up and down along the longitudinal direction of the upright plate 3.
[0038] Preferably, the aforementioned depth measuring components are provided in four sets, and the four sets of depth measuring components correspond exactly to the four sets of mounting holes on the partition. When the shelf 4 is lowered, the four sets of depth measuring components can be inserted into the mounting holes to perform depth detection on the mounting holes.
[0039] The depth measuring component includes a fixed cylinder 7 fixedly mounted on the shelf 4. A depth measuring structure is provided inside the fixed cylinder 7. During the descent of the shelf 4, the depth measuring structure can be inserted into the mounting hole on the partition, and the length of the depth measuring structure can be adjusted according to the appropriate depth of the mounting hole.
[0040] The depth measuring structure includes a trigger rod 13 slidably disposed within the fixed cylinder 7. A sleeve ring 1301 is fixedly disposed on the trigger rod 13. A second protrusion 1302 is formed on the outer wall of the sleeve ring 1301. The second protrusion 1302 is slidably disposed within a through groove 701 opened on the fixed cylinder 7. Figure 5 , Figure 6 Due to the cooperation between the second protrusion 1302 and the through groove 701, the trigger rod 13 of the sleeve ring 1301 can only slide along the axial direction of the fixed cylinder 7.
[0041] The depth measuring structure also includes a plug tube 16 fixedly coaxially with the trigger rod 13, and a plug rod 14 is slidably disposed inside the plug tube 16. The plug rod 14 is threadedly connected to a rotating cylinder 15 rotatably mounted on the plug tube 16.
[0042] Specifically, please refer to Figure 5 , Figure 6 , Figure 7The outer wall of the aforementioned insertion rod 14 is provided with an external thread 1401, which is threadedly connected to the internal thread formed on the inner wall of the rotating cylinder 15; and a fixing rod 17 is coaxially fixedly provided inside the aforementioned insertion cylinder 16, which is inserted into the insertion slot 18 opened on the insertion rod 14; in particular, a protrusion 1701 is fixedly provided on the outer wall of the fixing rod 17, which is slidably provided in the groove 1801 opened on the inner wall of the insertion slot 18. With the cooperation of the protrusion 1701 and the groove 1801, the insertion rod 14 can only move up and down along the axial direction of the fixing cylinder 7; therefore, the rotation of the rotating cylinder 15 can change the distance between the lower end face of the insertion rod 14 and the shelf 4, so that during the movement of the shelf 4, the depth of the mounting holes with different depth requirements can be detected, and the overall operation is simple.
[0043] Further, please refer to Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 The fixed cylinder 7 is provided with a positioning component. During the descent of the depth measuring structure, the depth measuring structure can drive the positioning component to move according to the depth of the mounting hole. When the depth of the mounting hole is appropriate or insufficient, the positioning component can lock the position of the depth measuring structure. When the depth of the mounting hole is insufficient, the depth measuring structure can simultaneously turn on the signal light 20 provided in the fixed cylinder 7.
[0044] Specifically, please refer to Figure 5 , Figure 6 The aforementioned signal light 20 is fixedly installed inside the fixed cylinder 7, and an elastic trigger button is provided on the side of the signal light 20 facing the support platform 2. When the trigger button is subjected to external force, the signal light 20 will be lit, and after the external force is removed, the trigger button will reset, and the signal light 20 will turn off automatically after being lit for a period of time, so that the inspectors can identify the lit signal light 20 and mark the unqualified installation holes.
[0045] The positioning component includes a rotating sleeve 8 rotatably mounted on the fixed cylinder 7. The inner wall of the rotating sleeve 8 is provided with a composite groove. The second protrusion 1302 is slidably disposed in the composite groove. During the descent of the placement plate 4, the second protrusion 1302 cooperates with the composite groove to drive the rotating sleeve 8 to rotate and position the trigger rod 13.
[0046] For details, please refer to Figure 5 , Figure 6The aforementioned fixed cylinder 7 is also equipped with a spring 12, one end of which abuts against the signal light 20, and the other end abuts against the sleeve ring 1301. Specifically, the spring 12 is always in a compressed state, pushing the sleeve ring 1301 away from the signal light 20, so that in the initial state, the sleeve ring 1301 is in contact with the lower end face of the fixed cylinder 7. When performing the installation hole depth test, first rotate the rotating cylinder 15 to change the distance between the lower end face of the insertion rod 14 and the rotating cylinder 15, so that this distance is equal to the qualified hole depth of the installation hole to be tested. Then, use the lifting mechanism to control the placement plate 4 to descend. During the descent, the bottom surface of the installation hole presses against the insertion rod 14, forcing the insertion rod 14 to drive the trigger rod 13 to rise relative to the fixed cylinder 7. During this process, the second protrusion 1302 cooperates with the composite groove to ultimately lock the position of the trigger rod 13. The specific details are as follows:
[0047] When the depth of the installation hole to be tested is qualified, the composite groove cooperates with the second protrusion 1302 so that the rotating sleeve 8 locks the position of the trigger rod 13 and the trigger rod 13 does not trigger the signal light 20.
[0048] When the depth of the mounting hole to be tested is shallow, the trigger rod 13 rises to a higher height, which can trigger the indicator light 20. At the same time, the rotating sleeve 8 locks the position of the trigger rod 13. During the subsequent reset of the placement plate 4, the indicator light 20 will flash in the fixing cylinder 7 corresponding to the shallow mounting hole, so that the testing personnel can mark it.
[0049] When the depth of the mounting hole to be tested is relatively deep, the trigger rod 13 rises to a relatively low height. At this time, the trigger rod 13 fails to trigger the indicator light 20, and the rotating sleeve 8 cannot lock the position of the trigger rod 13. During the subsequent reset process of the placement plate 4, the insertion rod 14 returns to its initial state under the action of the spring 12. That is, the lower end face of the insertion rod 14 corresponding to the deeper mounting hole is lower than the lower end face of the insertion rod 14 that is found to have a qualified mounting hole depth and is too shallow, so that the testing personnel can mark it.
[0050] For details, please refer to Figure 9 , Figure 10 The composite groove includes a spiral groove 803 formed on the inner wall of the rotating sleeve 8. One end of the spiral groove 803 is connected to a vertical groove 802, and the other end is connected to a buffer groove 19. The buffer groove 19 is as follows: Figure 10 As shown, it includes a lower groove surface 1902 and an inclined groove surface 1901;
[0051] In conjunction with the above, during the descent of the shelf 4, the mounting hole forces the insert rod 14 to rise relative to the fixed cylinder 7. During this process, the second protrusion 1302 first slides within the vertical groove 802, and then engages with the spiral groove 803. As the shelf 4 continues to descend, the second protrusion 1302 can force the rotating sleeve 8 to rotate counterclockwise (see reference). Figure 9 , Figure 10 (Description) When the mounting hole depth is qualified, after the shelf 4 descends to the lowest height, the second protrusion 1302 just disengages from the spiral groove 803. Then, when the shelf 4 rises, during the process of the spring 12 pushing the trigger rod 13 to reset, the second protrusion 1302 will fall onto the lower groove surface 1902, thereby locking the position of the trigger rod 13.
[0052] When the mounting hole is shallow, when the shelf 4 descends to the lowest position, the relative displacement of the trigger rod 13 increases compared to the above qualified condition. At this time, the trigger rod 13 can trigger the indicator light 20 so that the indicator light 20 emits a light signal. During the subsequent process of the spring 12 pushing the trigger rod 13 to reset, the second protrusion 1302 will fall onto the inclined groove surface 1901 and, under the guidance of the inclined groove surface 1901, finally combine with the lower groove surface 1902, thereby locking the position of the trigger rod 13.
[0053] When the mounting hole is deep, when the placement plate 4 descends to the lowest position, compared with the above qualified condition, the relative displacement of the trigger rod 13 is reduced. At this time, the trigger rod 13 fails to trigger the signal light 20. At the same time, the second protrusion 1302 fails to move to the position of disengaging from the spiral groove 803. Subsequently, the spring 12 pushes the trigger rod 13 back to the initial position so that the inspection personnel can mark and position it.
[0054] Furthermore, please refer to Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 The rotating sleeve 8 is also provided with an unlocking structure, which includes a piston cylinder 9 fixedly mounted on the fixed cylinder 7, a piston rod 10 slidably mounted inside the piston cylinder 9, the piston rod 10 being fixedly connected to a sleeve cylinder 11 mounted on the rotating sleeve 8, and a first protrusion 1101 being formed on the inner wall of the sleeve cylinder 11, the first protrusion 1101 being slidably mounted in a rotating groove 801 opened on the outer wall of the rotating sleeve 8;
[0055] Specifically, there is a certain frictional resistance between the piston rod 10 and the piston cylinder 9, so that the piston rod 10 can slide relative to the piston cylinder 9 only when subjected to external force.
[0056] The unlocking structure also includes a trigger, which includes a fixing plate 5 fixedly mounted on the upright plate 3. An abutment rod 6 is fixedly mounted on the fixing plate 5. During the upward movement of the placement plate 4, the abutment rod 6 can force the piston rod 10 to slide relative to the piston cylinder 9.
[0057] In the initial state, the first protrusion 1101 is located at the end of the stroke of the rotating groove 801 near the support platform 2. In conjunction with the above, when the depth of the mounting hole is qualified or too shallow, the rotating sleeve 8 rotates counterclockwise. During this process, the rotating groove 801 can force the first protrusion 1101 to drive the sleeve 11 and the piston rod 10 to rise relative to the piston cylinder 9 until the rotating sleeve 8 is locked. Then, the first protrusion 1101 moves to the end of the stroke of the rotating groove 801. During the subsequent rise of the shelf 4, the piston rod 10 will contact the abutment rod 6. As the shelf 4 continues to rise, the abutment rod 6 forces the piston rod 10 to fall. At this time, the first protrusion 1101 cooperates with the rotating groove 801 to force the rotating sleeve 8 to rotate clockwise so that the second protrusion 1302 disengages from the lower groove surface 1902. Combined with the release of elastic potential energy by the spring 12, when the shelf 4 is reset, all the insert rods 14 return to the initial state so that the depth of the mounting hole of the partition can be checked again.
