[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0023] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0025] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central 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 a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0028] A profile sealing structure includes a first elastic gasket 3 and a profile 2. The end face of the profile 2 is provided with a groove 21 for installing the first elastic gasket 3. The depth of the groove 21 is less than the thickness of the first elastic gasket 3. The first elastic gasket 3 is installed in the groove 21. When two profiles are fixed, the end face of one of the profiles is fixed to the side face of the other profile. The first elastic gasket 3 on the end face abuts against the side face of the other profile, and the first elastic gasket 3 is squeezed, thereby ensuring the sealing between the profiles.

[0029] In the profile sealing structure, since the depth of the slot 21 is less than the thickness of the first elastic gasket 3, the first elastic gasket 3 is squeezed between the profile 2 and fits tightly with the profile 2. When two profiles 2 need to be installed together, the end face of one of the profiles 2 is fixed to the side of the other profile 2, and the end face of the first elastic gasket 3 abuts against the side of the other profile 2 to form a seal. The slot 21 position has no gaps due to the first elastic gasket 3 inserted, achieving a sealing effect. In the same way, multiple profiles can be fixed together and assembled to form a complete profile frame 4, so that the joints of each profile can achieve a sealing effect. In addition, using this method, welding or gluing processes can be avoided, saving a lot of time and technical requirements required for welding; professional tools required for the gluing process are eliminated, saving the time required for manual gluing, and saving costs.

[0030] In the utility model, a plurality of fixing areas 20 are further provided at the end of the profile, and the plurality of fixing areas 20 are arranged at intervals around the periphery of the slot; when the end face of one of the profiles is fixed to the side face of the other profile, the fixing area 20 on the end face of the profile presses against the side face of the other profile, thereby ensuring the strength of the connection between the two profiles, and at the same time, the first elastic gasket 3 in the slot is compressed between the two profiles, thereby ensuring the sealing of the connection between the two profiles.

[0031] In the present invention, the side of the groove 21 extends to the outside of the profile 2. When the two profiles 2 are fixed, since the width of the first elastic gasket 3 is greater than the width of the groove 21, the side of the first elastic gasket 3 will also protrude and appear on the outside of the profile 2, and appear between two adjacent fixing areas 20. In this way, when another profile 2 is continued to be fixed on the side of the profile 2, the first elastic gasket 3 exposed on the side of the profile 2 is pressed against the first elastic gasket 3 exposed on the other profile 2 to form a seal (such as Figure 4 As shown), and the width R of the first elastic gasket 3 exposed between two adjacent fixing areas 20 is greater than the width between the two adjacent fixing areas 20 (as shown Figure 3 As shown), the sealing between the fixing area 20 and the first elastic gasket 3 can be ensured, thereby improving the overall sealing effect.

[0032] The following takes the assembly of a cubic sealed box using 4040 profile as an example (other profiles can also be used, and different profiles can be selected according to needs). First, multiple profiles are assembled using the above method to form a cubic sealed box frame 4. The connection between each profile is ensured by the fixing area 20 to ensure the strength, and the sealing effect is ensured by the first elastic gasket 3; the upper and lower surfaces and sides of the sealed box are all sealed and assembled.

[0033] In this embodiment, the upper and lower surfaces of the sealing box are respectively assembled with upper and lower sealing assemblies 5, and the upper and lower sealing assemblies 5 include a pressing plate 50 and fixing screws 51 for fixing the pressing plate 50, upper and lower sealing plates 52, and a second elastic gasket 53. The second elastic gasket 53 is laid flat on the profile 2, and the upper and lower sealing plates 52 cover the second elastic gasket 53 to squeeze the second elastic gasket 53 to play a sealing role. The pressing plate 50 plays a role in protecting the upper and lower sealing plates 52. The fixing screws 51 fix the pressing plate 50 to the profile 2, and the upper and lower sealing assemblies 5 are respectively installed on the top and bottom of the sealing box to achieve sealing of the top and bottom of the sealing box.

[0034] The side sealing assembly 6 of the sealing box includes a U-shaped sealing strip 60 and a side sealing plate 61. The U-shaped sealing strip 60 is U-shaped, wraps around the side sealing plate 61, and is embedded in the mounting groove 1, thereby ensuring the sealing of three sides.

[0035] The fourth side is used to install the movable door 7. The movable door 7 assembly includes a door panel 70, a door fixing screw 71, an external fixing plate 72, a hinge 73, a hinge fixing block 74, a magnet suction plate 75 and a door sealing strip 76. The door sealing strip 76 includes a straight segment and an arc segment. The straight segment is embedded in the installation groove 1, and the arc segment is embedded in the post-processed arc groove. The door panel 70 has an external fixing plate 72 and a magnet suction plate 75 fixed by the door fixing screw 71. The external fixing plate 72 plays a role in protecting the door panel 70. The magnet suction plate 75 is attracted with the magnet 8 to ensure that the door sealing strip 76 fits the door panel 70, thereby ensuring the sealing of the movable door 7 assembly. The movable door 7 assembly is fixed to the frame 4 through the hinge 73 and the hinge fixing block 74, which ensures the strength of the frame and the overall sealing.

[0036] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
