Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1 to 3, a double ring glass assembly 100 provided in the present embodiment includes an outer casing 10, an inner glass 20 and an outer glass 30 disposed in the outer casing 10, and further includes a first sealing ring 40, a second sealing ring 50, a third sealing ring 60, an isolation assembly 70, a first fixing member 80, a pressure plate 90 and a second fixing member (not shown).

The inner glass 20 has a flat plate-like structure. The first sealing ring 40 is sleeved on the outer side surface of the inner glass 20 and can extend towards two oppositely arranged surfaces of the inner glass 20 to form a first skirt edge 41. In this embodiment, the first sealing ring 40 is made of a material with good elasticity, such as silicone.

The outer ring glass 30 is a ring structure, and is sleeved outside the inner glass 20. The outer ring glass 30 includes an inner peripheral surface 31 and an outer peripheral surface 32 which are opposite to each other. The second sealing ring 50 is sleeved on the inner circumferential surface 31 and can extend towards two opposite surfaces of the outer ring glass 30 to form a second skirt 51. The second seal ring 50 is disposed opposite the first seal ring 40. The third seal ring 60 is disposed on the outer peripheral surface 32 and extends toward two opposite surfaces of the outer ring glass 30 to form a third skirt 61. The third seal ring 60 is sandwiched between the housing 10 and the outer ring glass 30. In the embodiment, the second sealing ring 50 and the third sealing ring 60 are made of a material with good elasticity (such as silicone), so that the elastic characteristics of the first sealing ring 40, the second sealing ring 50 and the third sealing ring 60 are utilized to effectively enhance the sealing effect among the inner glass 20, the outer ring glass 30 and the outer shell 10.

The isolation assembly 70 is used for isolating the inner glass 20 from the outer ring glass 30, and simultaneously, by extruding the first sealing ring 40 and the second sealing ring 50, the gap between the first sealing ring 40 and the inner glass 20 and the gap between the second sealing ring 50 and the outer ring glass 30 are reduced, so that the air tightness between the inner glass 20 and the outer ring glass 30 is improved, and the waterproof effect is enhanced. The spacer assembly 70 includes a spacer 71 and a positioning member 72. In the present embodiment, the spacer 71 and the positioning element 72 are both ring-shaped structures. The spacer 71 includes a pressing portion 711 and an extending portion 712. The pressing portion 711 is pressed on the same side of the first skirt 41 as the second skirt 51. The extension 712 is interposed between the first and second seal rings 40 and 50 until it protrudes from the other sides of the first and second skirts 41 and 51. The positioning member 72 is pressed against the other sides of the first skirt edge 41 and the second skirt edge 51 and is fixedly connected with the spacer 71, thereby completing the assembly of the inner glass 20 and the outer ring glass 30, improving the air tightness between the outer ring glass 30 and the inner glass 20, and enhancing the waterproof effect.

The first fixing member 80 is used for locking the isolation member 71 and the positioning member 72, so that the isolation member 71 and the positioning member 72 are fixed more firmly; and simultaneously, the inner glass 20 is fixedly connected with the outer ring glass 30 by matching with the isolation component 70. The first fixing member 80 may be at least one of a screw, a bolt, and a pin.

The outer peripheral surface of the outer ring glass 30 is fixedly connected to the housing 10. The pressing plate 90 is used to improve the air tightness between the outer ring glass 30 and the outer casing 10 and enhance the waterproof effect. Specifically, a stepped annular groove 11 is formed on an end surface of the housing 10, and includes an inner groove 110 and an outer groove 112 that are coaxially disposed. The inner groove 110 has a smaller diameter than the outer groove 112 to form a stepped surface 113. The outer ring glass 30 is embedded in the inner groove 110 and pressed against the bottom surface of the inner groove 110. The third seal ring 60 fills the gap between the outer ring glass 30 and the sidewall of the inner groove 110, thereby improving the airtightness between the outer ring glass 30 and the casing 10 and enhancing the waterproof effect. The pressing plate 90 is pressed on the step surface 113 and the third seal ring 60 at the same time.

The second fixing member is used for fixing the pressing plate 90 on the step surface 113, and is matched with the pressing plate 90 to realize the fixed connection between the outer ring glass 30 and the outer shell 10. The second fixing member may be at least one of a screw, a bolt, and a pin.

The assembly process of the double ring glass assembly 100 is as follows: fixing a first seal ring 40 on the side surface of the inner glass 20, and fixing a second seal ring 50 and a third seal ring 60 on the inner circumferential surface 31 and the outer circumferential surface 32 of the outer ring glass 30 respectively; an isolation assembly 70 and a first fixing member 80 are arranged between the inner glass 20 and the outer ring glass 30, so that the inner glass 20 is fixedly connected with the outer ring glass 30; next, the pressing plate 90 and the second fixing member are installed between the outer glass 30 and the housing 10, thereby fixing the inner glass 20 and the outer glass 30 to the housing 10.

Compared with the prior art, the double-ring glass assembly has the advantages that the first sealing ring, the second sealing ring and the third sealing ring are used for filling gaps among the inner glass, the outer ring glass and the shell respectively, so that the situation that the outer ring glass and the inner glass are easy to fall off or crack due to stress concentration of the glass can be effectively avoided, and the air tightness is improved; meanwhile, the inner glass, the outer ring glass and the shell are assembled and fixed in a mechanical connection mode, so that the glass is suitable for the outer ring glass and/or the inner glass which are large in area and heavy in weight. Further, the dicyclo glass subassembly of this application can also carry out dismouting or maintenance according to the user's demand, and is very convenient.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
