[0028] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0029] In the description of this application, it should be understood that the terms "height", "thickness", "up", "down", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting this application. In the description of this application, "plurality" means two or more, and at least one means one, two, or more than two, unless otherwise clearly and specifically defined.

[0030] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked X indicates the length direction of the box, the arrow marked Y indicates the width direction Y of the box, and the arrow marked Z indicates the height direction of the box. The length direction X, width direction Y and height direction Z are introduced to more clearly express the structure and relative position relationship of each component in the airtight detection equipment. In actual application, the length direction X, width direction Y and height direction Z may change according to the different placement methods of the airtight detection equipment.

[0031] As a preface to the embodiments of the present application, the airtightness detection equipment mainly includes an air pump, an airtightness detector, and a power supply, which are connected to each other through corresponding air paths and / or circuits; when there is a need for airtightness detection in outdoor scenes, the equipment needs to be carried to the site. At this time, each component needs to be moved one by one, which is relatively time-consuming. Especially when it is operated by an individual, the time required will increase, which brings many inconveniences to carrying and using the airtightness detection equipment on site.

[0032] Please combine Figure 1 and Figure 2 The airtightness detection device of the embodiment of the present application includes a housing 1, an air pump 2 and an airtightness detector 3. The housing 1 has a receiving cavity 111, and the housing 1 is provided with an operation port 121 connected to the receiving cavity 111. The air pump 2 and the airtightness detector 3 are both arranged in the receiving cavity 111, wherein the air pump 2 is connected to the airtightness detector 3 through a pipeline so that the airtightness detector 3 can obtain gas pressure or vacuum, and the operation end of the airtightness detector 3 is exposed through the operation port 121. The air pump 2 and the airtightness detector 3 are isolated from the external environment by the housing 1 to play a protective role.

[0033] Specifically, the operating port 121 is arranged on one side surface of the outer periphery of the box body 1. The operating end of the airtightness detector 3 refers to the side of the airtightness detector 3 having the operating panel and the connection port. The inspector can directly connect and use it without taking out the airtightness detector 3, which is simple and convenient.

[0034] Since the air pump 2 and the air tightness detector 3 are integrated in the box body 1, the air pump 2 and the air tightness detector 3 can be transported to the site together by simply moving the box body 1, saving the time required for multiple transports, thereby facilitating on-site use. In addition, the setting of the operating port 121 makes it unnecessary to remove the air tightness detector 3 after the equipment arrives at the site, so the pipelines of the air pump 2 and the air tightness detector 3 can be connected in advance, and the air tightness detector 3 can be connected for operation after the equipment is in place, which is conducive to further improving the convenience of on-site use.

[0035] Please refer to Figure 2In some embodiments, the airtightness testing device further includes a power module 4, which is disposed in the accommodating cavity 111 and electrically connected to the airtightness detector 3. The power module 4 is used to power the airtightness testing device, eliminating the need for additional on-site power connection of the airtightness testing device and facilitating the use of the device.

[0036] Please combine Figure 2 and Figure 3 In some embodiments, the airtightness testing device further includes a bracket 5, which is fixed to the bottom wall of the box 1. The airtightness tester 3 is connected to the top side of the bracket 5, and the power module 4 is disposed between the bracket 5 and the bottom wall of the box 1. Specifically, the power module 4 can be located directly below the airtightness tester 3, or can be offset from the airtightness tester 3 to a certain extent. The main purpose is to arrange the power module 4 and the airtightness tester 3 along the height direction Z of the box 1 to fully utilize the space of the box 1 in the height direction Z, thereby reducing the size requirement of the box 1 in the width direction Y.

[0037] In the embodiment of the present application, the airtightness detector 3 and the power module 4 are fixed by a detachable connection to facilitate the replacement of airtightness detectors 3 and power modules 4 of different specifications, and the detachable connection structure can adopt one of screws, bolts, and pins. In some other embodiments, the airtightness detector 3 and the power module 4 can also be installed by welding.

[0038] In some other embodiments, the power module 4 is connected to the top side of the bracket 5, and the airtightness detector 3 is arranged between the bracket 5 and the bottom wall of the box 1. The relative positions of the power module 4 and the airtightness detector 3 can be adjusted according to their own specifications to avoid interference with the air pump 2.

[0039] Please combine Figure 3 、 Figure 4 and Figure 5 In some embodiments, the airtightness detection device further includes a bracket 5, an adapter 6 and a fastener 7. The adapter 6 is respectively connected to the bracket 5 and the airtightness detector 3 through the fastener 7, so that the airtightness detector 3 is fixed to the top side of the bracket 5. The number of adapters 6 can be multiple, and at least a portion of each adapter 6 is located between the airtightness detector 3 and the bracket 5. Alternatively, the adapter 6 is respectively connected to the bracket 5 and the power module 4 through the fastener 7, so that the power module 4 is fixed to the top side of the bracket 5. Accordingly, the number of adapters 6 can be multiple, and at least a portion of each adapter 6 is located between the power module 4 and the bracket 5.

[0040] The adapter 6 is provided with a plurality of mounting holes 61 and a plurality of waist-shaped holes 62 at one end close to the bracket 5. Each mounting hole 61 is connected to a waist-shaped hole 62, and each waist-shaped hole 62 extends along a first direction, which is the width direction Y or the length direction X of the box body 1. The inner diameter of the mounting hole 61 is larger than the width of the waist-shaped hole 62. The fastener 7 passes through the waist-shaped hole 62 to form a snap fit with the waist-shaped hole 62.

[0041] The adapter 6 is Z-shaped as a whole and can be processed by sheet metal bending technology; the fastener 7 can be one of screws, bolts, and pins. For example, the fastener 7 in this embodiment is connected by screws. When connecting the adapter 6 and the airtightness detector 3, the threaded section of the screw passes through the adapter 6 and the housing of the airtightness detector 3 from bottom to top, and is threadedly connected to the housing of the airtightness detector 3; when connecting the adapter 6 and the bracket 5, the threaded section of the screw can be connected to the bracket 5 in advance, and then the head of the screw is passed through the mounting hole 61, and the airtightness detector 3 is moved along the extension direction of the waist-shaped hole 62, so that the threaded section of the screw is relatively moved into the waist-shaped hole 62. At this time, this side of the adapter 6 is stuck between the bracket 5 and the head of the screw, which limits the displacement of the adapter 6, thereby completing the fixation of the airtightness detector 3, which is convenient and quick. When it is necessary to connect the adapter 6 and the bracket 5, its connection method can refer to the airtightness detector 3 and will not be repeated here.

[0042] Please refer to Figure 3 In some embodiments, the bracket 5 is provided with an escape portion 51, and at least a portion of the air pump 2 is located within the escape portion 51. The escape portion 51 allows the air pump 2 to occupy a portion of the space of the bracket 5 when placed, thereby meeting the placement requirements of the overall size of the air pump 2. At the same time, the escape portion 51 also increases the horizontal dimension between the escape portion 51 and the inner side surface of the accommodating cavity 111 opposite to it, thereby allowing the installation of air pumps 2 of different specifications and increasing the adaptability of the device.

[0043] Please refer to Figure 3 In some embodiments, the air pump 2 and the bracket 5 are arranged along the length direction X of the box 1. That is, the air tank of the air pump 2 is placed along the length direction X of the box 1. The arrangement of the air pump 2 and the bracket 5 can fully utilize the space along the length direction X of the box 1, minimize the width requirement of the box 1 due to the placement of the air pump 2, and thus reduce the volume of the box 1 for easier portability.

[0044] Please refer to Figure 3In some embodiments, the airtightness detection device further includes a plurality of support frames 8, which connect the box body 1 and the air pump 2 to achieve a detachable connection of the air pump 2, thereby assembling air pumps 2 of different specifications. Specifically, the support frame 8 is fixed to the inner bottom wall of the accommodating cavity 111 by screws, and a recess is provided on the top side of the support frame 8. The recess is arc-shaped, and the gas tank of the air pump 2 is clamped in the recess and then supported above the bottom wall of the box body 1 by each support frame 8. In some other embodiments, one end of the support frame 8 can also be screwed or welded to the gas tank of the air pump 2, and the other end can be screwed to any inner wall of the accommodating cavity 111.

[0045] Please combine Figure 1 、 Figure 2 and Figure 3 In some embodiments, the housing 1 includes a main body 11 and a door 12. The main body 11 has a accommodating cavity 111. The main body 11 is provided with a first opening 112 connected to the accommodating cavity 111. The door 12 is hinged to the main body 11 and has an open state and a closed state. When the door 12 is in the open state, the first opening is exposed to facilitate assembly, maintenance and other operations. When the door 12 is in the closed state, the door 12 covers the first opening 112 to protect the equipment inside the housing 1. The door 12 is provided with an operating port 121 that passes through it in the thickness direction. The operating end of the airtightness detector 3 is arranged on the side of the first opening 112, which can facilitate the adjustment of its relative position with the operating port 121 when the airtightness detector 3 is assembled through the first opening 112 without changing the orientation.

[0046] Please combine Figure 1 、 Figure 2 and Figure 3 In some embodiments, the airtightness detection device further includes a cover plate 9 and a flange 100. A second opening 113 is provided on the top side of the main body 11. The second opening 113 is connected to the accommodating cavity 111. The cover plate 9 is covered on the second opening 113. The flange 100 is provided around the outer periphery of the cover plate 9 and is connected to the cover plate 9, forming a 90° angle between the two. The second opening 113 is located on the inner side of the flange 100. The second opening 113 increases the operable space during equipment assembly, and the equipment can be flexibly placed from the side of the box body 1 or hung from the top of the box body 1. In addition, the main body 11 in this embodiment is mainly composed of profiles and plates. The profiles form a rectangular frame structure, and the plates are connected between two adjacent profiles to form the accommodating cavity 111. At this time, the flange 100 surrounds the outer side of the vertically arranged profiles and plates, playing a role in stabilizing the frame structure.
