Description

Technical Field

[0001] The utility model relates to the field of air tightness detection devices, in particular to a simple device for detecting air tightness. Background Art

[0002] The air tightness of the device deserves attention during the production process. Leakage of the device may lead to leakage of harmful gases, failure to meet the specified production conditions, etc. Therefore, a good air tightness of the device is conducive to safe production and production efficiency.

[0003] The principles of the current common methods for detecting gas leaks vary, and they mainly detect changes in gas concentration, temperature, sound or smell to find leaks, including the use of gas detection instruments, infrared cameras, ultrasonic detection, odor detection and other methods. Compared with the above methods, the bubble detection method has the characteristics of easy availability of raw materials and convenient use, and has been widely used in the production process. However, the bubble method requires the operator to pay great attention, and it may happen that the bubbles cannot be observed or the bubbles will burst and disappear quickly, making observation difficult. Therefore, this application proposes a simple device for detecting airtightness, which has a simple overall structure and low production cost, and is convenient for detection personnel to quickly determine whether there is a leak and the leak point. Utility Model Content

[0004] The utility model aims to provide a simple device for detecting air tightness to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A simple device for detecting air tightness comprises a whistle and a connecting belt, wherein the whistle and the connecting belt are respectively provided with a plurality of groups, the whistle is connected with a clamping ring, and buckles are respectively connected at both ends of the connecting belt, the buckles cooperate with the clamping ring, the buckles are rotatably connected with a sealing rod, the buckles are connected with a spring, and the free end of the spring is connected with the sealing rod.

[0007] Preferably, the whistle is connected with a rubber grommet.

[0008] Compared with the prior art, this technical solution produces the following beneficial effects:

[0009] (1) The technical solution uses multiple groups of whistles to detect the air tightness of the device. The multiple groups of whistles are connected in series through connecting belts, so that the multiple groups of whistles can be tied to the device to be detected, which is easy to operate. When the device leaks, the leaked gas will make the whistle make a sound. The inspector can quickly determine the leakage of the device and the leakage point. There is no need for the inspector to concentrate for a long time, which improves the sensitivity of the detection signal; the whistle and the connecting belt are fastened together by means of buckles and clamps, and the corresponding number of whistles can be connected according to the actual situation. It is also convenient to select the corresponding length of the connecting belt according to the actual situation to adjust the distance between two adjacent groups of whistles, which greatly improves the applicability of the device and is convenient for disassembly and storage, which greatly improves the practicality.

[0010] (2) The whistle of the present technical solution is connected with a rubber gasket, so that it can fit the device more closely to avoid air leakage, so that even a small airflow can make the whistle make a sound, thereby improving the detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0017] like Figures 1 to 4 A simple device for detecting air tightness shown in the figure includes a whistle 1 and a connecting belt 5. The structure of the whistle 1 and the principle of how the whistle 1 makes a sound are well known to practitioners in the field and will not be elaborated here. The whistle 1 and the connecting belt 5 are respectively provided with several groups. The left and right sides of the whistle 1 are respectively connected with a clamping ring 2, and the two ends of the connecting belt 5 are respectively connected with a buckle 4. The buckle 4 cooperates with the clamping ring 2, and the buckle 4 can be buckled with the clamping ring 2 to realize the series connection of multiple groups of whistles 1. The buckle 4 is rotatably connected to a sealing rod 6, and the buckle 4 is connected to a spring 7, and the free end of the spring 7 is connected to the sealing rod 6; the whistle 1 is connected to a rubber gasket 3; the rubber gasket 3 is located at the air inlet of the whistle 1.

[0018] The specific implementation process is as follows:

[0019] like Figure 2 As shown, when the buckle 4 is not in use, the sealing rod 6 contacts the buckle 4 under the action of the spring 7, so that the buckle 4 is closed. When in use, the sealing plate is pressed to rotate it clockwise, thereby opening the opening of the buckle 4 and compressing the spring 7. Then, the buckle 4 can be clamped on the clamping ring 2, and then the sealing rod 6 is loosened. Under the action of the restoring force of the spring 7, the sealing rod 6 rebounds and closes the opening of the buckle 4, completing the connection between the connecting belt 5 and the whistle 1. In the above manner, multiple groups of whistles 1 are connected in series. After the connection is completed, both ends of the detection device are connected with the connecting belt 5, and then the device is sleeved on the outside of the device to be detected, so that the rubber gasket 3 is connected to the device to be detected. The surface of the device is in contact with each other, and then the two groups of connecting belts 5 are fastened to each other or fixed in a binding manner through two groups of buckles 4, so that the detection device can be stably wrapped and bound on the outer surface of the device to be detected, and then the ventilation detection is started. When the device does leak, air will escape from the leakage point, and the air will make the whistle 1 make a sound after being ejected from the leakage point. The staff can quickly determine whether there is a leak and the leakage point, and can adjust the position of the whistle 1 and the device to be detected according to the detection situation to conduct a comprehensive detection of the device. After the detection is completed, the device can be removed. The structure is simple, easy to use, and the production cost and use cost are low.

[0020] The technical solution detects the air tightness of the device through multiple groups of whistles, and connects the multiple groups of whistles in series through the connecting belt 5, so that the multiple groups of whistles can be tied to the device to be detected, which is easy to operate. When the device leaks, the leaked gas will make the whistle make a sound, and the detection personnel can quickly determine the leakage of the device and the leakage point, without the need for the detection personnel to concentrate for a long time, thereby improving the sensitivity of the detection signal; the whistle and the connecting belt 5 are fastened together by means of the buckle 4 and the clamp ring 2, and the corresponding number of whistles can be connected according to the actual situation. It is also convenient to select the corresponding length of the connecting belt 5 according to the actual situation to adjust the distance between the two adjacent groups of whistles, which greatly improves the applicability of the device and is convenient for disassembly and storage, greatly improving the practicality; the whistle 1 is connected with a rubber gasket 3, so that it can fit the device more closely to avoid air leakage, so that a smaller airflow can also make the whistle make a sound, thereby improving the detection accuracy.

[0021] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
