[0022] The following describes the embodiments of the present invention in detail.
[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and are not to be construed as limiting the present invention.
[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0025] See also Figure 1-4 , the utility model provides a technical solution:
[0026] A shell sealing structure includes a shell 1, a through opening is provided on the front side of the shell 1, a sealing plate 2 is installed in the through opening, a mounting assembly is provided between the shell 1 and the sealing plate 2, the mounting assembly includes an insert plate 4 and an elastic card plate 5 respectively arranged at the bottom and top of the sealing plate 2, two insert plates 4 are symmetrically arranged on both sides of the bottom surface of the sealing plate 2, the two insert plates 4 can disperse stress and prevent the insert plates 4 from breaking due to stress concentration, thereby indirectly improving the service life of the insert plates 4 and the device, the elastic card plate 5 is composed of a V-shaped plate of elastic material and a flat extension plate, the V-shaped plate of elastic material makes the front end of 5 deformable and can be inserted into the card slot 105, and after being inserted into the card slot 105, it can also tightly contact the card slot 105 to limit the sealing plate 2, the bottom and top of the plate slot 101 are respectively provided with a slot 104 and a card slot 105 corresponding to the insert plate 4 and the elastic card plate 5.
[0027] During installation, first insert the inserting plate 4 into the slot 104 , and then push the sealing plate 2 upwards. The elastic clamping plate 5 is elastically deformed into the clamping groove 105 after being squeezed, thereby achieving installation positioning and preliminary sealing of the sealing plate 2 .
[0028] The above design eliminates the need for third-party tools to install and connect the housing 1 and the sealing plate 2 , making assembly and disassembly of the sealing plate 2 more convenient during installation and maintenance.
[0029] A sealing assembly is installed on the sealing plate 2, and the sealing assembly includes an airbag 3, which is inflatable; a mounting ring 201 is provided on the sealing plate 2, and the airbag 3 is sleeved on the mounting ring 201; a plate groove 101 is provided in the shell 1, and an airbag groove 102 is provided in the plate groove 101, the plate groove 101 is adapted to the sealing plate 2, and the airbag groove 102 is adapted to the airbag 3, and an inflation port 301 is provided on the front of the airbag 3, and a connecting hole 204 is provided on the sealing plate 2, and the inflation port 301 passes through the connecting hole 204 and is provided on the front of the shell 1.
[0030] The airbag 3 can fit tightly against the inner wall of the mounting ring 201 and the airbag groove 102 by inflation, forming an effective sealing barrier. This sealing method can significantly reduce or eliminate leakage problems caused by gaps or uneven surfaces, ensuring that the sealing performance of the equipment or system meets the design requirements.
[0031] The sealing assembly has a simple and clear structural design, and the installation process is convenient and quick. At the same time, when the sealing assembly needs to be maintained or replaced, it can be carried out by simply disassembling it, which greatly reduces maintenance costs and time.
[0032] Moreover, the inflation port 301 is arranged on the front of the housing 1, which is convenient for the user to perform the inflation operation and improves the user's convenience. At the same time, this design also makes the monitoring and inspection of the sealing state more intuitive and convenient.
[0033] By adopting the above design, the sealing cap on the inflation port 301 can be unscrewed during use, and the airbag 3 can be inflated through the inflation port 301, so that the airbag 3 is inflated and expanded, fitting tightly on the inner wall of the mounting ring 201 and the airbag groove 102, thereby achieving complete sealing between the shell 1 and the sealing plate 2.
[0034] In this way, even if an error occurs in the installation of the sealing ring 203, the inflation seal of the airbag 3 can completely block the airbag groove 102, thereby completely sealing the connection between the shell 1 and the sealing plate 2 to prevent water from entering the interior of the shell 1.
[0035] It also includes a secondary sealing component, which includes a sealing ring 203. A mounting groove 202 is provided on the mounting ring 201. The sealing ring 203 is sleeved in the mounting groove 202. The mounting grooves 202 have three linear arrays and are evenly spaced at the lower end of the outer wall of the mounting ring 201. A docking groove 103 is provided on the airbag groove 102. The docking groove 103 is adapted to the sealing ring 203. The number and position of the docking grooves 103 correspond to the mounting grooves 202.
[0036] By adding a sealing ring 203 to the mounting ring 201 of the sealing plate 2 and opening a corresponding docking groove 103 on the airbag groove 102 of the housing 1, a double sealing structure is achieved, thereby effectively enhancing the overall sealing reliability and reducing the risk of leakage.
[0037] The design of the mounting grooves 202 and the docking grooves 103 adopts a linear array with equal spacing, making the distribution of the sealing rings 203 more uniform on the sealing surface. This design helps to achieve a more uniform sealing pressure distribution and avoids the problem of sealing failure caused by local pressure concentration.
[0038] In this solution, the airbag 3 is used as the main sealing element, which is inflated to achieve a tight fit with the shell 1 to form a first sealing barrier.
[0039] At the same time, the compression deformation of the sealing ring 203 is utilized to achieve close cooperation with the docking groove 103, thereby forming a second sealing barrier. The two sealing barriers work together to ensure the waterproof performance of the housing.
[0040] Even if there is an error in the installation of the sealing ring 203, the sealing cap on the inflation port 301 can be unscrewed, and the airbag 3 can be inflated through the inflation port 301, so that the airbag 3 is inflated and expanded, completely filling the airbag groove 102, thereby achieving complete sealing between the shell 1 and the sealing plate 2.
[0041] Furthermore, a heat dissipation component is also provided on the sealing plate 2, and the heat dissipation component includes a breathable waterproof membrane 6. A heat dissipation port connected to the shell 1 is opened on the sealing plate 2, and the breathable waterproof membrane 6 is arranged in the heat dissipation port. There are multiple heat dissipation ports opened at equal intervals in a linear array.
[0042] The breathable waterproof membrane 6 is a PVC waterproof breathable membrane with excellent water resistance, acid and alkali resistance, and chemical corrosion resistance.
[0043] A protective cover 601 is provided on the outside of the heat dissipation port. The protective cover 601 is L-shaped, with its opening facing downward and closed on both sides. The number and position of the protective cover 601 correspond to the heat dissipation port.
[0044] The provision of the breathable waterproof membrane 6 allows the heat dissipation vent to allow air to circulate freely and take away the heat generated inside the device, while also ensuring that moisture does not enter the device. The protective cover 601, through its special L-shaped structure, effectively blocks rain and debris, protecting the heat dissipation vent and the breathable waterproof membrane 6 therein from rain.
[0045] The combined use of the breathable waterproof membrane 6 and the protective cover 601 effectively improves the heat dissipation effect of the device while ensuring waterproof performance, thereby extending the service life of the device.
[0046] Working principle:
[0047] During installation, first insert the plug plate 4 into the slot 104, and then push the sealing plate 2 upward so that the sealing ring 203 enters the docking groove 103. The elastic card plate 5 is elastically deformed and enters the card slot 105 after being squeezed, thereby achieving the installation positioning and preliminary sealing of the sealing plate 2.
[0048] Then the sealing cap on the inflation port 301 can be unscrewed, and the airbag 3 can be inflated through the inflation port 301, so that the airbag 3 is inflated and expanded, and the airbag 3 is inflated and expanded, and fits tightly on the inner wall of the mounting ring 201 and the airbag groove 102, thereby achieving complete sealing between the shell 1 and the sealing plate 2.
[0049] In this way, even if an error occurs in the installation of the sealing ring 203, the inflation seal of the airbag 3 can completely block the airbag groove 102, thereby completely sealing the connection between the shell 1 and the sealing plate 2 to prevent water from entering the interior of the shell 1.
[0050] When the device is working, such as in hot weather, the heat generated by the device in the shell 1 can also be discharged through the heat dissipation vents. The breathable waterproof membrane 6 in the heat dissipation vents can prevent moisture from entering while allowing air to circulate in the heat dissipation vents, thereby preventing water from entering the shell 1 and causing short circuit damage to electrical components.
[0051] Since the breathable waterproof membrane 6 is relatively soft, it is easy to break due to external influences. The setting of the protective cover 601 can ensure the ventilation effect of the breathable waterproof membrane 6 while preventing external debris from contacting the breathable waterproof membrane 6 and causing the breathable waterproof membrane 6 to break and be damaged.
[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
