Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass installation protection technology, and more specifically, to a concealed fan structure with high safety performance. Background Technology
[0002] While aluminum alloy concealed sash casement windows currently on the market look attractive, they pose significant safety hazards. This is primarily because the glass in the concealed sash is directly glued to the operable sash with structural adhesive, without any other safety measures. Often, the glued glass can fall due to external forces, or the adhesive may crack over time, causing the glass to detach and jeopardize the window, posing a serious risk to people's lives and property. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a concealed fan structure with high safety performance.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A high-safety concealed sash structure includes a concealed sash body for mounting glass. The concealed sash body has a left side and a right side. A left limiting frame is provided on the left side of the concealed sash body, and a support strip is detachably connected to the right side of the concealed sash body. A stop edge is provided on the side of the support strip away from the concealed sash body. After the glass is installed on the concealed sash body, the left limiting frame and the stop edge cooperate to prevent the glass from moving left or right on the concealed sash body.
[0006] Furthermore, in this invention, the aforementioned retaining edge and the aforementioned support strip are detachably connected via an adjustment mechanism.
[0007] Furthermore, in this utility model, the aforementioned adjustment mechanism is a screw.
[0008] Furthermore, in this invention, the glass is bonded to the aforementioned concealed fan body using structural adhesive.
[0009] The beneficial effects of this utility model are:
[0010] This invention provides a high-safety concealed sash structure. A stop is installed at the right end of the support strip using screws. The height of the stop can be designed according to actual conditions. After the glass is installed, the portion of the glass between the left limiting frame and the stop is prevented from shifting in the lateral direction, thus ensuring structural stability. Furthermore, the distance between the stop and the support strip can be adjusted by adjusting the screws, allowing this concealed sash structure to accommodate glass of varying thicknesses within a certain size range. Attached Figure Description
[0011] Figure 1This is a structural schematic diagram of an embodiment of the present utility model.
[0012] In the diagram: 101 - concealed fan body; 201 - left limiting frame; 301 - support strip; 401 - edge guard; 501 - screw; 601 - structural adhesive; 701 - glass. Detailed Implementation
[0013] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0014] Please see Figure 1 This utility model provides a technical solution:
[0015] A high-safety concealed sash structure includes a concealed sash body 101 for mounting glass 701, which is connected to the outer frame of the window. The concealed sash body 101 has a left side and a right side. A left limiting frame 201 is installed on the left side of the concealed sash body 101, and a support strip 301 is detachably connected to the right side of the concealed sash body 101. To facilitate the installation of the support strip 301, a special limiting groove is designed on the concealed sash body 101. Correspondingly, a limiting block that matches the limiting groove is installed at one end of the support strip 301. After the limiting block is engaged with the limiting groove, a stable connection is achieved between the support strip 301 and the concealed sash body 101.
[0016] To improve the stability of the glass 701 mounted on the concealed fan body 101, from Figure 1 From a certain perspective, a retaining edge 401 is installed on the right end of the support strip 301 using screws 501. The height of the retaining edge 401 can be designed according to the actual situation. In this way, after the glass 701 is installed, on the one hand, the part of the glass 701 located between the left limiting frame 201 and the retaining edge 401 is restricted by the two and cannot be displaced in the left and right directions, thus ensuring the stability of the structure; on the other hand, the distance between the retaining edge 401 and the support strip 301 can be adjusted by adjusting the screws 501, so that this concealed sash structure can install glass 701 of different thicknesses within a certain size range.
[0017] To facilitate the connection between the glass 701 and the concealed fan body 101, and to ensure a soft contact between the glass 701 and the concealed fan body 101, in this embodiment, the glass 701 can be bonded to the concealed fan body 101 using structural adhesive 601. Structural adhesive 601 can also be injected between the edge 401 and the glass 701.
[0018] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
