Description

Technical Field

[0001] The utility model relates to the technical field of screen windows, in particular to a screen window body lock for a casement screen window. Background Art

[0002] A screen is a fabric installed on a window or door to block insects from entering the house. It is made of a thin mesh material that can block mosquitoes, flies and other small insects while allowing air to circulate to keep the room clean and cool. Window screens are fixed to the window frame and slide inside the window's mounting frame.

[0003] A Chinese patent discloses an easy-to-clean screen with a protective function (authorization announcement number CN202544722U). The patented technology includes a screen frame and a screen net. The junction of the screen frame and the screen net is fixed and pasted by a mother-and-child sticker. The plastic surface of the mother-and-child sticker is arranged around the screen frame, and the silk surface of the mother-and-child sticker is arranged around the screen net. A protective rod is arranged horizontally on the screen frame. Compared with the prior art, the easy-to-clean screen with a protective function of the utility model has the characteristics of simple structure, easy processing, easy cleaning and replacement of the screen net, protective function, and easy maintenance.

[0004] This patented technology has the advantage of being significantly easier to clean and disassemble when in use, but there are still some shortcomings during use. The screen window is slidably installed inside the mounting frame, and there is a lack of a locking structure between the screen window and the mounting frame, so that the screen window is easy to slide in the frame under strong winds or under the influence of external impacts, causing the window to open and lose the function of intercepting mosquitoes, flies and other small insects. The use process is unstable. Therefore, a technician in this field provides a screen window lock for a casement screen window to solve the problems raised in the above background technology.

[0039] Example 1

[0040] See also Figure 1-Figure 4 As shown, this embodiment is a screen window lock for a casement screen window, comprising a mounting frame 100,

[0041] The screen window structure 200 includes a window frame 201, an upper guide rail 202 located on the inner wall of the upper end of the installation frame 100, a lower guide rail 204 located on the inner wall of the lower end of the installation frame 100, a slider 203 fixed to the upper end of the window frame 201, a docking seat 205 located on the outer side of the lower end of the window frame 201, a screen 206 located inside the window frame 201, and a slide groove 209 opened inside the lower end of the docking seat 205 and slidably sleeved on the outer wall of the lower guide rail 204;

[0042] The slider 203 is slidably sleeved on the outer wall of the upper guide rail 202;

[0043] A travel groove 207 is provided inside the docking seat 205, and the lower end of the window frame 201 is slidably installed inside the travel groove 207;

[0044] A symmetrically distributed compression spring 208 is provided at the upper end of the travel groove 207, and the upper and lower ends of the compression spring 208 are respectively connected to the outer wall of the lower end of the window frame 201 and the inner wall of the lower end of the travel groove 207;

[0045] The lower end of the window frame 201 is provided with symmetrically distributed travel holes 211, and the upper end of the travel groove 207 is provided with a guide rod 210 located inside the compression spring 208, and the upper end of the guide rod 210 is slidably inserted into the travel hole 211;

[0046] Using the screen window structure 200;

[0047] When the window frame 201 is installed, the docking seat 205 is docked on the lower guide rail 204, and the window frame 201 applies a downward force to the docking seat 205. The window frame 201 squeezes the compression spring 208, and the compression spring 208 shrinks under the force, the window frame 201 drops, and the slider 203 is located under the upper guide rail 202, relaxing the window frame 201. The compression spring 208 lifts the window frame 201 through its own elasticity, and the upper end of the window frame 201 is installed on the outer side of the upper guide rail 202 through the slider 203, thereby realizing the convenient installation of the window frame 201.

[0048] Example 2

[0049] See also Figure 1-Figure 4 As shown, this embodiment is based on the embodiment 1 and also includes:

[0050] as well as;

[0051] The locking structure 300 includes a mounting hole 307, an insertion rod 301 opened inside the window frame 201 and the slider 203, located inside the mounting hole 307, a positioning block 305 located at the upper end of the insertion rod 301, a spring 302 sleeved on the outside of the insertion rod 301, and a positioning hole 306 opened inside the lower end of the upper slider 203.

[0052] A support ring 304 is provided on the inner wall of the mounting hole 307, a limit ring 303 is sleeved on the outer wall of the upper end of the insertion rod 301, the upper and lower ends of the spring 302 are respectively connected to the limit ring 303 and the support ring 304, a pull ring 308 is provided on the lower end of the insertion rod 301, the positioning holes 306 are equidistantly distributed, and the upper end of the positioning block 305 is inserted into the positioning hole 306;

[0053] Performing the use of the locking structure 300;

[0054] When the screen window is in use, the pull ring 308 is pulled to pull the insertion rod 301, which drives the support ring 304 to apply force to the spring 302. The spring 302 contracts under the force, and the plug moves out of the positioning hole 306, and the window frame 201 is slid. After the window frame 201 reaches the specified position, the pull ring 308 is loosened, and the spring 302 pushes the insertion rod 301 to rise through its own elasticity. When the plug is inserted into the corresponding positioning hole 306, the window frame 201 is elastically engaged. When the screen window needs to be opened to let in sunlight, the screen window is kept stable to avoid sliding and closing due to wind, which causes the sunlight of the screen 206 to be weakened. When it needs to be closed to intercept mosquitoes, the closed window frame 201 is engaged and positioned to avoid the problem of opening due to wind.
