Description

Technical Field

[0001] The utility model belongs to the field of pipeline interfaces, and in particular relates to a pipeline interface structure and gas leak detection equipment. Background Art

[0002] A gas leak detector is an analytical instrument that uses the mass-to-charge ratio of ionized molecules or atoms to determine the composition and structure of a sample. Its working principle is based on the principle that charged particles can be deflected in an electromagnetic field. By separating and detecting the mass differences of atoms, molecules, or molecular fragments of a substance, it can analyze the composition of the substance. With the rapid development of the domestic electrical industry, gas leak detection equipment has been widely used in lithium battery gas leakage detection scenarios. For example: Application No. 202311816948.X, named, Electrolyte Leak Detection Method and Device, discloses leakage detection of lithium batteries.

[0003] In the prior art, a leakage detection device for a lithium battery typically includes a vacuum chamber, the interior of which is used to place the battery cell to be tested. Specifically, during use, when it is necessary to test the battery cell to be tested, the vacuum chamber is opened and the battery cell to be tested is placed into the vacuum chamber; after the test of the battery cell to be tested is completed, the vacuum chamber is opened again and the battery cell to be tested is removed from the vacuum chamber. Therefore, during the process of taking the battery cell in and out, the vacuum chamber is connected to the outside, and impurities and foreign matter in the external environment can easily enter the interior of the vacuum chamber. Once impurities enter the vacuum chamber, the impurities and foreign matter will move along the pipes connected to the vacuum chamber, posing a risk of impurities and foreign matter entering the components and causing damage. Utility Model Content

[0004] The utility model provides a pipeline interface structure and a gas leak detection device, which aims to solve the problem of impurities entering the pipeline.

[0005] In order to achieve the above object, the utility model provides a pipeline interface structure, comprising

[0006] A vacuum chamber, wherein a side wall of the vacuum chamber is configured with a mounting groove, and an inner wall of the mounting groove is provided with a locking unit;

[0007] The locking unit includes a sliding cavity, a locking pin and a spring. The locking pin is slidably mounted in the sliding cavity. The sliding cavity is constructed on the inner wall of the mounting groove. The locking pin is mounted inside the sliding cavity, and the front end of the locking pin extends to the mounting groove. The spring is mounted in the sliding cavity, and the two ends of the spring are respectively connected to the locking pin and the bottom of the sliding cavity.

[0008] a pipeline, wherein the pipeline is installed on the side wall of the vacuum chamber, and the inlet of the pipeline is located in the installation groove;

[0009] A filter component is installed in the installation groove, and a locking groove is provided on the outer side wall of the filter component, and the locking groove is used to be engaged with the locking pin.

[0010] In this solution, a filter is installed at the entrance of the pipeline to block impurities in the vacuum chamber and prevent them from entering the pipeline. At the same time, this solution uses the locking unit and locking groove to achieve a detachable connection, facilitating subsequent cleaning and maintenance of the filter.

[0011] Preferably, in order to ensure a better locking effect of the locking unit on the filter component and a more stable fixation of the filter component, the locking units of this solution are provided with at least two, and are respectively provided on the inner walls of both sides of the mounting groove; the filter component is also constructed with at least two locking grooves, and the locking grooves correspond one-to-one with the locking structures.

[0012] This solution is adapted by at least two locking units and locking grooves. Compared with only one locking unit and locking groove, the locking effect of the filter component by the locking unit is better, and the filter component is not easily separated from the side wall of the vacuum chamber.

[0013] Preferably, in order to facilitate the installation of the filter component into the installation groove without distinguishing between the upper and lower ends, the locking units on both sides and the locking grooves on both sides of the present solution are arranged to be symmetrical to each other.

[0014] In this solution, the locking unit and the locking groove are symmetrical, so the upper and lower ends of the filter component are not restricted. Even if the upper and lower ends of the filter component are reversed, the locking unit and the locking groove can still correspond one to one. This design reduces the steps for the user to distinguish the upper and lower ends of the filter component, making it easier to use.

[0015] Preferably, in order to facilitate the separation of the locking groove and the ejector pin, the front end of the locking pin in this solution is hemispherical, and the locking groove is a hemispherical groove.

[0016] Preferably, in order to facilitate the user to remove the filter component from the installation groove, the side wall of the filter component of this solution is provided with an operating groove, and the operating groove is symmetrically arranged on the side walls of the filter component.

[0017] Preferably, in order to solve the problem that the operating groove is blocked by the side wall of the installation groove, the operating groove in this solution is located outside the locking groove.

[0018] In order to make it easier to remove the filter component, the operating groove and the locking groove in this solution are distributed in a cross shape.

[0019] Preferably, in order to achieve directional positioning of the filter component and ensure that the locking groove is accurately moved to a position adapted to the locking unit, the mounting groove and the filter component in this solution are both elliptical, and the filter component is installed in the mounting groove.

[0020] In this solution, because both the mounting slot and the filter element are elliptical, the filter element can only be installed into the mounting slot at a specific angle. When the filter element enters the mounting slot at that specific angle, the locking slot moves along a specific path, precisely moving to a position that matches the locking unit.

[0021] In order to solve the problem of impurities entering the pipeline of a gas leak detection device, the second aspect of the present invention discloses a gas leak detection device including the above-mentioned pipeline interface structure. The above-mentioned pipeline interface structure is used in the gas leak detection device to prevent impurities from entering the pipeline.

[0022] The beneficial effects of the present invention are as follows: 1. A filter component is arranged at the inlet of the pipeline, which blocks impurities in the vacuum chamber and prevents the impurities from entering the pipeline.

[0023] 2. The locking unit and the locking groove cooperate with each other to achieve a detachable connection, which is convenient for subsequent cleaning and maintenance of the filter components. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the objectives, technical solutions, and advantages of the embodiments more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0031] In this disclosure, unless otherwise specified, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not convey order or importance.

[0032] Example 1

[0033] Basically as attached Figure 1 As shown, a pipeline interface structure includes a vacuum chamber, a pipeline 2 and a filter component 3. The interior of the vacuum chamber is used to place the battery cell to be tested. The specific shape and structure of the vacuum chamber can be a vacuum chamber used for placing battery cells in the prior art, and this embodiment does not limit it. Pipeline 2 is specifically a metal pipeline 2, and pipeline 2 is used for the electrolyte to be tested to pass through. Pipeline 2 is installed on the outer wall of the vacuum chamber, and pipeline 2 is in a connected state with the interior of the vacuum chamber. Filter component 3 is installed at the inlet of pipeline 2, and filter component 3 can filter impurities to prevent impurities from entering the interior of pipeline 2.

[0034] like Figure 2 As shown, to facilitate subsequent cleaning and replacement of the filter component 3, the filter component 3 is detachably mounted. During implementation, the inner sidewall of the vacuum chamber is configured with a mounting groove 11, which is specifically an elliptical groove. Locking units 4 are symmetrically disposed on the left and right sidewalls of the mounting groove 11. At least two locking units 4 are provided, and in implementation, two, three, or four locking units can be provided on each side. The at least two locking units 4 can better secure the filter component 3, preventing the filter component 3 from becoming disengaged from the mounting groove 11.

[0035] like Figure 3As shown, the specific structure of the locking unit 4 in the embodiment of the present disclosure includes a sliding cavity 41, a locking pin and a spring 43. The sliding cavity 41 is arranged on the inner wall of the mounting groove 11, and the sliding cavity 41 is a cylindrical slide. The entrance of the sliding cavity 41 faces the middle of the mounting groove 11. The locking pin is cylindrical as a whole, and the top of the locking pin is hemispherical. The locking pin is installed inside the sliding cavity 41, and the locking pin can slide inside the sliding cavity 41. The bottom of the locking pin is fixedly connected to one end of the spring 43, for example, by welding. The other end of the spring 43 is connected to the inner bottom of the sliding cavity 41, for example, by bonding. The spring 43 is used to hold the locking pin against the front end of the locking pin so that the front end of the locking pin extends into the mounting groove 11. At the same time, when the front end of the locking pin is subjected to extrusion force, the locking pin can be pressed into the sliding cavity 41.

[0036] like Figure 4 As shown, the filter component 3 of the disclosed embodiment includes a filter screen and a mounting ring. The mounting ring is an elliptical ring, and the filter screen is disposed on the inner ring of the mounting ring. The size of the mounting ring is slightly smaller than the size of the mounting groove 11, so that the mounting ring can be embedded and installed inside the mounting groove 11. To adapt to the locking unit 4, the mounting ring of the disclosed embodiment is provided with locking grooves 31 on the left and right sides. The locking grooves 31 are preferably hemispherical grooves. There are also at least two locking grooves 31, the number of which is the same as the number of locking units 4, and the locking grooves 31 and the locking units 4 are provided in a one-to-one correspondence.

[0037] For example, when filter component 3 is inserted into mounting slot 11, the locking pin in locking unit 4 fits into locking slot 31 on the side of filter component 3. The locking pin and locking slot 31 engage with each other, securing filter component 3 within mounting slot 11. To remove filter component 3 for cleaning or replacement, simply pull filter component 3 toward the outside of mounting slot 11 to remove it.

[0038] It should be noted that because the mounting groove 11 and the filter element 3 are elliptical, the filter element 3 must be installed at a specific angle when it is installed into the mounting groove 11. The mounting groove 11 has a certain positioning function. Through the above design, when the filter element 3 is installed into the mounting groove 11, the locking pin of the locking unit 4 can be accurately embedded in the mounting groove 11, ensuring that the locking pin can effectively lock the filter element 3.

[0039] In order to facilitate the removal of the filter component 3 from the outside of the installation groove 11, an operation groove 32 is further provided on the outside of the installation ring in the embodiment of the present disclosure. Figure 4As shown. The operating groove 32 can be a circular groove or a rectangular groove, etc. The operating groove 32 is located at the top and bottom of the mounting ring. That is, the operating grooves 32 located at the top and bottom of the mounting ring and the locking grooves 31 located on the left and right sides of the mounting ring are distributed in a cross shape. At the same time, in order to prevent the operating groove 32 from being blocked by the side walls of the mounting groove 11, the embodiment of the present disclosure sets the operating groove 32 on the outside of the locking groove 31. That is to say, when the filter component 3 is installed on the mounting groove 11, the operating groove 32 is in an exposed state, which is convenient for the user to remove the filter component 3 from the mounting groove 11 through the operating groove 32.

[0040] To ensure a tight seal between the filter component 3 and the mounting groove 11, an annular sealing ring, which can be a rubber ring, is provided at the inner bottom of the mounting groove 11 in the disclosed embodiment. When the filter component 3 is installed in the mounting groove 11, the outer contour of the bottom of the filter component 3 contacts the sealing ring, which deforms to fill the gap between the filter component 3 and the mounting groove 11, preventing impurities from entering the pipe 2 through the gap.

[0041] The following is a further detailed description using a specific embodiment: During normal use, the filter component 3 is installed in the mounting groove 11 and is secured by the locking unit 4 and the locking groove 31. When cleaning and maintenance of the filter component 3 is required, the filter component 3 can be separated from the mounting groove 11 by pulling the filter component 3 outward. The separated filter component 3 can be cleaned and maintained.

[0042] Example 2

[0043] The embodiment of the present disclosure is improved on the basis of embodiment 1, such as Figure 5 As shown, in embodiment 1, each time the filter element 3 is removed, the ejector pin 42 will scrape against the side of the locking groove 31. Therefore, after repeated use, the locking groove 31 or the ejector pin 42 is easily damaged.

[0044] To address the aforementioned issues, in the disclosed embodiment, a long copper block 33 is preferably provided on the sidewall of the filter element 3, with a locking groove 31 formed on the copper block 33. The copper block 33 is configured with fasteners to enable detachable installation. Furthermore, the ejector pin 42 is preferably made of high-strength steel.

[0045] For example, if the ejector pin 42 scrapes against the side of the locking groove 31, the locking groove 31 is easily damaged by the scraping because it is constructed on the copper block 33, while the ejector pin 42 is not easily damaged. If the locking groove 31 is damaged by the scraping, only the copper block 33 needs to be removed and replaced.

[0046] Example 3

[0047] The present disclosure provides a gas leak detection device, which includes the pipeline interface structure and a gas leak detection device body in Example 1. The gas leak detection device body can be a gas leak detection device in the prior art, such as the gas leak detection device disclosed in Application No. 202311816948.X.

[0048] The vacuum chamber described in Example 1 was incorporated into conventional gas leak detection equipment. The vacuum chamber specifically accommodates the sample being tested. A pipe 2 connects to the vacuum chamber, allowing the sample to flow through. A filter 3 is located at the inlet of pipe 2, acting as a barrier.

[0049] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
