Description

Technical Field

[0001] This utility model relates to the technical field of bucket lid inspection tools, and in particular to a tool for inspecting the installation of bucket lid gaskets. Background Technology

[0002] There are significant quality control and safety risks in the production and use of cleanroom containers. Cleanroom containers are typically pre-installed with gaskets and liquid-collecting tubes before leaving the factory. However, during subsequent filling, operators only open the end without the tube. Therefore, whether the container lid with the liquid-collecting tube and the double gaskets were correctly installed before leaving the factory becomes a critical quality control point. Currently, conventional inspection methods mainly rely on visual inspection, sometimes even requiring unscrewing the lid for secondary confirmation. However, this method, when performed in non-cleanroom areas, easily introduces the risk of contamination. Furthermore, the process of inserting and removing the liquid-collecting tube and gaskets is complex, with a high possibility of omissions. If an omission occurs, it could lead to liquid leakage, resulting in serious production accidents and economic losses. Utility Model Content

[0023] The technical solutions in specific embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] In this embodiment of the utility model, in conjunction with reference to the reference Figures 1 to 4 As shown, a tool for inspecting the installation of bucket lid gaskets is provided. This tool mainly consists of a fastening part 1 and a sinking detection part 2. The bottom of the fastening part 1 has a fastening connection structure that precisely matches the outer contour of the bucket lid, and its interior has a through-groove running vertically, providing a guiding channel and accommodating space for the movement of the sinking detection part 2. The sinking detection part 2 moves smoothly along the axial direction of the through-groove, moving within the through-groove of the fastening part 1 based on its own weight or external pressure. When the fastening part 1 is fastened onto a bucket lid with a gasket, the height of the upper end face of the sinking detection part 2 from the gasket is higher than or equal to the height of the upper end face of the fastening part 1 from the gasket, thus forming a clear observation mark. In actual testing, if the height difference between the two upper ends changes abnormally, it means that no gasket is installed on the bucket lid, thereby achieving rapid and accurate detection of the bucket lid gasket installation status.

[0026] Specifically, the bottom of the fastening part 1 is provided with a ring-shaped array of snap-fit ​​structures 3. These snap-fit ​​structures 3 are specially designed to form a firm and stable snap-fit ​​with the grooves or recesses on the outer circumference of the lid. This design not only facilitates the quick and accurate installation of the fastening part 1 into the recesses on the outer circumference of the lid, but also effectively maintains the structural stability of the entire testing tool during operation, avoiding inaccurate test results due to external vibration or operational errors. The bottom of the sinking detection part 2 is provided with a lid opening block 4 whose shape matches the opening of the lid. It can pass through the lid opening and abut against the surface of the gasket when there is a gasket inside the lid, and abut against the inner bottom surface of the lid when there is no gasket inside the lid, thereby achieving accurate detection of the installation status of the lid gasket.

[0027] To ensure the stability and controllability of the sinking detection unit 2 during movement, a double limiting structure is set between the sinking detection unit 2 and the fastening part 1. First, an annular limiting piece 5 is provided on the outer periphery of the sinking detection unit 2 and above the lid latch 4. This annular limiting piece 5 is located between the fastening part 1 and the lid latch 4, and its outer diameter is larger than the inner diameter of the groove of the fastening part 1. It can limit the excessive upward movement of the sinking detection unit 2 from below, ensuring that the sinking detection unit 2 always remains within its effective working range. Second, a U-shaped bracket 6 is fixedly installed on the top of the fastening part 1 and connected to the top of the sinking detection unit 2 through a telescopic rod 7. The extension stroke of the telescopic rod 7 is calculated to be slightly greater than the distance from the lid latch 4 to the inner bottom surface of the lid. It can limit the movement range of the sinking detection unit 2 from above, preventing it from detaching from the fastening part 1 due to excessive downward movement, thereby ensuring the structural integrity and operational reliability of the entire detection tool.

[0028] In this embodiment, regarding the detection and judgment mechanism: when the fastening part 1 is fastened to a bucket lid with a gasket, the upper surface of the sinking detection part 2 is flush with the upper surface of the fastening part 1; when the fastening part 1 is fastened to a bucket lid without a gasket, the upper surface of the sinking detection part 2 is lower than the upper surface of the fastening part 1. This change in height difference forms an intuitive detection indicator. Operators only need to observe the height difference between the sinking detection part 2 and the fastening part 1 to quickly and accurately determine whether a gasket is installed inside the bucket lid. To further enhance the visualization and warning effect of the detection results, a photosensitive sensor 8 is embedded in the inner wall of the top of the slot of the fastening part 1. This sensor is specially configured to quickly generate a detection signal when it detects that the upper surface of the sinking detection part 2 is lower than the upper surface of the fastening part 1, i.e., when it is determined that no gasket is installed inside the bucket lid. In this embodiment, the photosensitive sensor 8 specifically adopts an LED indicator light, which emits a bright red light when triggered. In actual operation, when there is a gasket inside the lid, the sinking detection part 2 cannot descend, and the indicator light can be blocked. When there is no gasket inside the lid, the sinking detection part 2 descends, the indicator light is exposed, and it emits a red light to illuminate the inside of the groove. This design allows operators to determine whether the upper surface of the sinking detection part 2 is lower than the upper surface of the fastening part 1 without relying on direct visual observation of the height difference. Instead, they can make a clearer and more precise judgment by observing the changes in the indicator light, greatly improving detection efficiency and accuracy. At the same time, the red light, as an internationally recognized warning signal, also corresponds to the potential safety risks when the gasket is not installed, playing a good safety reminder role. Preferably, an alarm can also be equipped, electrically connected to the photosensitive sensor 8. When the photosensitive sensor 8 generates a detection signal, the alarm will simultaneously emit an audible alarm, forming a dual audible and visual warning system.

[0029] In other specific embodiments, the detection and judgment mechanism can be adjusted by modifying the structural parameters of the fastening part 1 and the sinking detection part 2 to achieve different judgment logics. For example, when the fastening part 1 is fastened to a bucket lid with a gasket, the upper surface of the sinking detection part 2 is higher than the upper surface of the fastening part 1; when the fastening part 1 is fastened to a bucket lid without a gasket, the upper surface of the sinking detection part 2 is level with the upper surface of the fastening part 1. This reverse height difference detection logic can also effectively determine the installation status of the gasket. In addition, a scale mark can be set on the outer wall of the sinking detection part 2. By observing the relative change between the scale mark and the upper surface of the fastening part 1, the operator can intuitively and quantitatively determine whether a gasket is installed inside the bucket lid. This utility model is not limited to the above specific embodiments. Those skilled in the art can freely choose any of the aforementioned technical solutions based on actual application scenarios, or combine and optimize multiple solutions, or reset the detection logic according to specific working conditions, equipment parameters, and other actual situations.

[0030] In summary, this utility model, through the ingenious cooperation of the fastening part 1 and the sinking detection part 2, utilizes the difference in descent height of the sinking detection part 2 when the gasket is installed inside the lid versus when it is not, to achieve rapid and accurate detection of the gasket installation status inside the lid. The entire detection tool has a simple and practical structure, good detection effect, low risk of misjudgment, and high practical value and market promotion prospects.

[0031] It should be noted that, for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
