Description

Technical Field

[0001] The utility model belongs to the technical field of casement windows, in particular to a casement window which is convenient for replacing a screen window. Background Art

[0002] The window sash opens and closes along a certain horizontal direction, so it is called a "casement window".

[0003] When replacing the existing window screen net, the window screen frame needs to be completely disassembled and the window screen frame needs to be separated from the window screen track. Based on the above, the present application designs a method that can replace the window screen net without leaving the window screen frame off the track. Utility Model Content

[0004] The utility model aims at solving the problems existing in the prior art and proposes the following technical solutions:

[0005] A casement window for easy replacement of screens, comprising a screen frame and a screen panel spliced ​​and installed with the screen frame by bolts;

[0006] A pressing plate is installed on one side of the screen window panel close to the screen window frame, and the pressing plate is inserted into a pressing groove, and the pressing groove is arranged on the outer wall of the screen window frame.

[0007] When the screen mesh needs to be replaced, the bolts are removed. At this time, only the screen panel needs to be removed from the front of the screen frame to complete the replacement and removal of the screen mesh. There is no need to separate the screen frame from the screen track, and the replacement operation is convenient;

[0008] When the screen mesh is pre-installed between the screen frame and the screen panel, the side of the screen mesh is pressed into the pressing groove under the pressure cover of the pressing plate, so that the stability of the screen mesh pre-installed between the screen frame and the screen panel is guaranteed.

[0009] As a preferred embodiment of the above technical solution, an arc-shaped groove is opened on the inner wall of the pressing groove, and an arc-shaped block is inserted in the arc-shaped groove, and the arc-shaped block is installed at the end of the pressing plate.

[0010] The static friction between the screen window mesh, the screen window frame and the screen window panel during installation is increased, so that the stability of the installation is further improved.

[0011] As a preferred embodiment of the above technical solution, the bottom ends of the arc blocks are connected to the limiting grooves through elastic members, and the limiting grooves are provided at the top of the pressure plate.

[0012] Under the action of the elastic potential energy of the elastic member, after the bolt is removed, the screen panel can be slightly popped out with a certain gap between it and the screen frame, so as to facilitate the removal of the entire cover plate.

[0013] As a preferred embodiment of the above technical solution, the inner wall of the screen window panel is provided with a soft pad that contacts the screen window frame.

[0014] The soft pad forms a space between the screen frame and the screen panel to prevent the two from direct contact and collision.

[0015] The beneficial effects of the utility model are:

[0016] In the present application, when the screen mesh needs to be replaced, the bolts are removed. At this time, only the screen panel needs to be removed from the front of the screen frame to complete the replacement and disassembly of the screen mesh. There is no need to detach the screen frame from the screen track, and the replacement operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model: it includes: a screen window frame 1, a screen window panel 8 spliced ​​and installed with the screen window frame 1 by bolts 10; after the screen window mesh that needs to be replaced is placed on the front end of the screen window frame 1, the screen window panel 8 is covered on the front end of the screen window frame 1, and the screen window frame 1 and the screen window panel 8 and the screen window mesh are locked and installed by bolts 10. When the screen window mesh needs to be replaced, the bolts 10 are removed. At this time, it is only necessary to remove the screen window panel 8 from the front of the screen window frame 1 to complete the work of replacing and disassembling the screen window mesh, and there is no need to detach the screen window frame 1 from the screen window track, and the replacement operation is convenient.

[0024] like Figure 2 and Figure 3As shown, a pressure plate 3 is installed on the side of the screen panel 8 close to the screen frame 1, and the pressure plate 3 is inserted into the pressure groove 2, which is opened on the outer wall of the screen frame 1; when the screen mesh is pre-installed between the screen frame 1 and the screen panel 8, the side edge of the screen mesh is pressed into the pressure groove 2 under the pressure of the pressure plate 3, so that the stability of the pre-installation of the screen mesh between the screen frame 1 and the screen panel 8 is guaranteed.

[0025] like Figure 2 and Figure 3 As shown, an arc groove 7 is opened on the inner wall of the pressing groove 2, and an arc block 6 is inserted in the arc groove 7, and the arc block 6 is installed at the end of the pressing plate 3; under the understanding of Euler's formula, the static friction between the screen mesh and the screen frame 1 and the screen panel 8 is increased, so that the stability of the installation is further improved.

[0026] like Figure 3 As shown, the bottom ends of the arc blocks 6 are connected to the limit grooves 4 through elastic members 5, and the limit grooves 4 are provided at the top of the pressure plate 3; under the action of the elastic potential energy of the elastic members 5, after the bolts 10 are removed, the screen panel 8 can be slightly popped out with a certain gap between it and the screen frame 1, so as to facilitate the removal of the entire cover.

[0027] It should be noted that if Figure 3 As shown, in this embodiment, a spring is used as an elastic component to force the arc block 6 to pop out in the limiting groove 4, but in some other embodiments, other elastic components such as a spring leaf, an elastic pick, etc. can also be used.

[0028] like Figure 2 and Figure 3 As shown, the inner wall of the screen panel 8 is provided with a cushion 9 which abuts against the screen frame 1; the cushion 9 forms a gap between the screen frame 1 and the screen panel 8 to avoid direct contact and collision between the two, and the cushion 9 can be made of other soft materials such as rubber.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
