Description

Technical Field

[0001] The utility model relates to the technical field of zipper air tightness testing, in particular to a zipper air tightness testing device. Background Art

[0002] Airtight zipper is a zipper that uses airtight materials and special structural design to achieve high waterproof performance. Airtight zipper is mainly used in occasions that require high sealing, such as waterproof clothing, diving suits, etc., which can effectively prevent the intrusion of air and liquid.

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 5 , which is a zipper air tightness testing device of an embodiment of the utility model, includes a base 10, a sealing ring 20 attached to the top surface of the base 10, a pressing plate 30 installed on the top surface of the sealing ring 20, and a gas processing component 40 located on one side of the base 10; the gas processing component 40 is used to connect to the interior of the base 10.

[0030] The base 10 has a receiving cavity 11 in the middle, and an air passage 12 is provided on one side of the base 10 corresponding to the receiving cavity 11. One end of the air passage 12 is connected to the receiving cavity 11 inwardly, and the other end of the air passage 12 extends outwardly to the outside of the base 10 and is connected to the gas processing assembly 40. A plurality of internal thread holes 13 are evenly spaced around the periphery of the top of the base 10, and the internal thread holes 13 are used to position and connect the pressure plate 30.

[0031] The sealing ring 20 has a first through groove 21 in the middle thereof, which corresponds to the accommodating cavity 11. The sealing ring 20 has a plurality of first through holes 22 evenly spaced around its periphery, which correspond to the internal threaded holes 13 one by one.

[0032] The middle of the pressing plate 30 is provided with a second through slot 31, which corresponds to the first through slot 21. The periphery of the pressing plate 30 is evenly spaced with a plurality of second through holes 32, which correspond to the first through holes 22 one by one.

[0033] During the test, the zipper 50 is first placed between the sealing ring 20 and the pressing plate 30, and then the bolt 33 is used to penetrate the second through hole 32 and the first through hole 22 and then match the internal threaded hole 13 to achieve a fixed connection between the pressing plate 30, the sealing ring 20 and the base 10. Figure 4 and Figure 5 As shown, the zipper 50 is tightly sandwiched between the sealing ring 20 and the pressing plate 30, and the zipper 50 covers the accommodating cavity 11. The length of the zipper 50 is greater than the length of the accommodating cavity 11, and the width of the zipper 50 is greater than the width of the accommodating cavity 11.

[0034] The gas processing assembly 40 includes a column 41 located on one side of the base 10, an air intake pipe 42 passing through the column 41, and a barometer 43 installed on the front of the column 41; the barometer 43 is connected to the air intake pipe 42. One end of the air intake pipe 42 is connected to the airway 12 through a conduit 44, and the other end of the air intake pipe 42 is used to connect to a gas supply device, such as an air pump.

[0035] During the test, the air supply device is used to supply air to the interior of the accommodating cavity 11 to a certain amount and then the air supply device is turned off. Since the zipper 50 covers the top of the accommodating cavity 11, the air pressure in the accommodating cavity 11 is greater than the external atmospheric pressure. At this time, observe whether the air pressure measured by the barometer 43 decreases. If the count of the barometer 43 decreases, it means that the zipper 50 is leaking and the air tightness is unqualified; on the contrary, if the count of the barometer 42 remains stable, it means that the air tightness of the zipper 50 is qualified. Furthermore, a small amount of water can be injected into the interior of the second slot 31, and the water pressure is applied to the zipper 50. If the zipper 50 is leaking, the generation of bubbles can be visually observed.

[0036] The above-mentioned zipper air tightness testing device has a simple structure and is easy to use. The zipper 50 is tightly clamped between the sealing ring 20 and the pressure plate 30. The zipper 50 covers the accommodating cavity 11. The gas processing component 40 is used to supply gas to the inside of the accommodating cavity 11. The air tightness of the zipper 50 can be effectively detected by the barometer 43, which greatly improves the detection efficiency and is convenient and intuitive.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
