Abstract
Description
Technical Field
[0001] The invention belongs to the field of invisible screen windows, and in particular relates to a screen window slideway and a screen window. Background Art
[0002] In the prior art, invisible screens are rolled up or unfolded by a rotating shaft, and are also provided with a screen slideway, in which there is a clamping groove, and a wool strip is embedded in the clamping groove to install the screen. The wool strip has limited clamping force on the screen, and the screen will fall out of the clamping structure when encountering wind or other external forces, and the screen cannot play its due role. Summary of the invention
[0003] The purpose of the present invention is to provide a screen window slideway, which can effectively clamp the window screen so that the window screen is not easy to fall off.
[0004] The technical solution of the present invention is:
[0005] A screen window slideway comprises a shell and clamping wheels fixed in the shell, wherein the clamping wheels are arranged in pairs and the paired clamping wheels are pressed against each other.
[0006] The screen window slideway of the present invention is provided with clamping wheels, and the paired clamping wheels are pressed against each other, and when the invisible screen window is installed, the window screen can be clamped and fixed between the paired clamping wheels. In this way, when the screen window is opened or closed, the window screen is unrolled or rolled up by the reel under the rolling clamping of the clamping wheels, and when the screen window is used normally, the window screen is clamped and fixed between the paired clamping wheels, and at this time, it is not easy to fall out of the screen window slideway under the action of gravity or wind, and it is firm and reliable.
[0007] Preferably, the clamping wheel is a smooth wheel. Even if the clamping wheel is a smooth wheel, since the clamping wheels are arranged in pairs, the paired clamping wheels squeeze and press each other, and the clamping effect on the window screen is much greater than the technical solution without any clamping in the prior art. The wool strips in the prior art only play a dust-proof role, and have no clamping force on the window screen at all. Under the action of gravity or wind, the screen window will often fall out of the slide to form a gap, and flying insects and mosquitoes and flies will enter and exit from the gap, which will not play the role of the screen window. After the present invention uses a smooth wheel for clamping, the screen window is suspended in the screen window slideway, and will not fall off the slideway even if there is wind, and the entire screen window is tight and seamless. A more preferred solution is to set multiple pairs of clamping wheels along the slideway, so that the clamping effect is better.
[0008] Preferably, at least one of the paired clamping wheels is a toothed wheel. When there is a toothed wheel in the paired clamping wheels, the teeth of the toothed wheel will generate greater friction and the clamping effect will be better.
[0009] More preferably, the pair of clamping wheels is a pair of gears meshing with each other. When the pair of clamping wheels is a pair of gears meshing with each other, the window screen is clamped between the pair of gears, and when the screen window is opened or closed, the window screen is clamped in the meshing teeth of the two gears, and the window screen is unrolled or rolled up on the reel by the rotation of the two gears. When the screen window is in normal use, the window screen is clamped and fixed between the meshing teeth of the two clamped gears, and the clamping is firm and reliable. At this time, even if a certain external force is applied, it is not easy to fall out of the screen window slideway.
[0010] More preferably, one of the paired clamping wheels is a toothed wheel and the other is a grooved wheel, and the teeth of the toothed wheel and the grooves of the grooved wheel are pressed against each other. When one of the paired clamping wheels is a toothed wheel and the other is a grooved wheel, the window screen is clamped between the teeth of the toothed wheel and the grooves of the grooved wheel when the screen window is installed. When the screen window is opened or closed, the window screen is clamped between the teeth and the grooves, and the window screen is unrolled or rolled up on the reel by the rotation of the toothed wheel and the grooved wheel; and when the screen window is in normal use, the window screen is clamped and fixed between the relatively squeezed teeth and the grooves, and the clamping is firm and reliable. At this time, it is not easy to fall out of the screen window slideway under the action of a certain external force.
[0011] Preferably, the pair of clamping wheels is a first clamping wheel and a second clamping wheel; the first clamping wheel is a step wheel, and both wheel surfaces of the first clamping wheel are cylindrical surfaces; the second clamping wheel is a cylindrical wheel, and the small cylindrical wheel surface of the first clamping wheel is clamped with the wheel surface of the second clamping wheel, and the step surface of the first clamping wheel is clamped with the top surface of the second clamping wheel.
[0012] When installing the screen window, the window screen is clamped between the step surface of the first clamping wheel and the top surface of the second clamping wheel, and the small cylindrical wheel surface of the first clamping wheel and the wheel surface of the second clamping wheel are bent to bend the reinforcing edge of the screen window 90 degrees and clamp it to be installed on the screen window. When the screen window is opened or closed, the window screen is clamped under the rotation of the first clamping wheel and the second clamping wheel so that the window screen is unfolded or rolled up on the reel; and when the screen window is in normal use, the window screen is bent, clamped and fixed between the first clamping wheel and the second clamping wheel that are relatively squeezed. The 90-degree bend makes the clamping of the window screen less likely to fall off from between the first clamping wheel and the second clamping wheel, more firm and reliable, and less likely to fall off from the screen window slideway under the action of a certain external force.
[0013] The present invention also provides a screen window, which includes the above-mentioned screen window slide and window screen of the present invention, and a window screen clamping part is provided on the window screen, and the window screen clamping part is located at the two edges of the window screen, and the thickness of the window screen of the window screen clamping part is thickened; the window screen clamping part is used to clamp the window screen with a pair of clamping wheels.
[0014] After the window screen clamping part is provided, the thickness of the window screen at the window screen clamping part is thickened, and the clamping wheel in the window screen slideway clamps the window screen at the window screen clamping part, so the clamping effect is better and more durable. Since a pair of clamping wheels are installed in the window screen slideway of the present invention, the window screen can be effectively clamped when opening, closing and in normal use, so the window screen is not easy to fall off.
[0015] Preferably, a strip of polyurethane film for thickening the window screen is fixed to the window screen clamping portion.
[0016] The polyurethane film is arranged on the window screen clamping part, so that the window screen clamping part is stronger and has a certain hardness and toughness, which is conducive to the clamping of the clamping wheel. In addition, the polyurethane film has a certain bending resistance, making the window screen more durable when clamped by the clamping wheel.
[0017] More preferably, the window screen clamping part is provided with a row of square holes, and the row of square holes meshes with the toothed wheel. A row of square holes meshes with the toothed wheel, so that the gear teeth of the toothed wheel pass through the square holes, and the window screen is hung on the toothed wheel. Such a window screen will only fall off when the gear teeth are damaged, so the window screen is less likely to fall off.
[0018] The beneficial effects of the present invention are:
[0019] The screen window slideway of the present invention is provided with a pair of clamping wheels for squeezing and clamping the window screen, so that the window screen is firmly installed in the screen window slideway and is not easy to fall off. The screen window including the screen window slideway of the present invention is provided with a window screen clamping part at the top and bottom of the window screen for clamping the window screen by the pair of clamping wheels, so that the screen window can be effectively clamped when opening, closing and in normal use, and the window screen is not easy to fall off.

DETAILED DESCRIPTION
[0028] A screen window slideway of the present invention comprises a housing and clamping wheels fixed in the housing, wherein the clamping wheels are arranged in pairs, and the paired clamping wheels squeeze and press each other. The screen window including the screen window slideway of the present invention is provided with a screen clamping part on the screen, wherein the screen clamping part is located at both edges of the screen, and the screen thickness of the screen clamping part is thickened; the screen clamping part is used for clamping the screen by the paired clamping wheels. In this way, the present invention squeezes and clamps the screen by the paired clamping wheels in the screen window slideway, so that the screen is firmly installed in the screen window slideway and is not easy to fall off.
[0029] The present invention is described in detail below with reference to specific embodiments and accompanying drawings.
[0030] Example 1
[0031] This embodiment provides a screen window. Figure 1 : is the screen window structure diagram in this embodiment. Figure 1 As shown, the screen window includes a screen window slideway and a window screen 4, the screen window slideway includes a housing 1 and a clamping wheel fixed in the housing 1, the clamping wheels are arranged in pairs, and the pairs of clamping wheels squeeze and press each other: for example, the first clamping wheel 2 and the second clamping wheel 3 are a pair of clamping wheels, the first clamping wheel 2 and the second clamping wheel 3 are both smooth wheels, and the two squeeze each other to clamp and fix the window screen 4. In this embodiment, the slideways of the screen window are respectively arranged at both ends of the screen window, and multiple pairs of such clamping wheels are arranged in each screen window slideway to clamp the window screen together, Figure 2 FIG. 2 is a schematic diagram of the window screen clamping state in this embodiment. Figure 2, a window screen clamping part 41 is also provided on the window screen 4, and the window screen clamping part 41 is located at both edges of the window screen, and the window screen thickness of the window screen clamping part is thickened; the window screen clamping part is used for clamping the window screen 4 by the paired clamping wheels. In this embodiment, since the clamping wheels are arranged in pairs, the paired clamping wheels squeeze and press each other, and the clamping effect on the window screen is also much greater than the technical solution without any clamping in the prior art. The wool strips in the prior art only play a dustproof role and have no clamping force on the window screen at all. When installing the invisible screen window, the window screen is clamped and fixed in the screen window slideway with multiple pairs of clamping wheels. In this way, when the screen window is opened or closed, the window screen 4 is unfolded or rolled up on the reel 5 under the rolling clamping of multiple pairs of clamping wheels, and when the screen window is used normally, the window screen 4 is clamped and fixed between the paired clamping wheels. At this time, it is not easy to get out of the screen window slideway under the action of gravity or wind, and it is firm and reliable.
[0032] Example 2
[0033] This embodiment provides a screen window. Figure 3 is a structural diagram of the screen window in this embodiment. The difference between this embodiment and embodiment 1 is that one of the pair of clamping wheels is a toothed wheel and the other is a grooved wheel. Figure 3 As shown, in the housing 1 of the screen slideway, the clamping wheels are arranged in pairs, and the pairs of clamping wheels are pressed against each other. Figure 3 In the embodiment, the first clamping wheel 2 and the second clamping wheel 3 are a pair of clamping wheels, wherein the first clamping wheel 2 is a groove wheel and the second clamping wheel 3 is a toothed wheel. Figure 4 FIG. 2 is a schematic diagram of the clamping state of the window screen in the window screen slideway in this embodiment. Figure 4 As shown, the gear teeth 31 of the second clamping wheel 3 and the wheel groove 21 of the first clamping wheel 2 are pressed against each other, and a window screen clamping portion 41 is provided at the edge of the window screen. When the screen window is installed, the clamping portion 41 of the window screen 4 is clamped between the gear teeth 31 of the toothed wheel and the wheel groove 21 of the groove wheel. When the screen window is opened or closed, the window screen 4 is clamped between the gear teeth 31 and the wheel groove 21, and the window screen 4 is unfolded or rolled up on the reel 5 by the rotation of the geared wheel and the groove wheel; and when the screen window is in normal use, the window screen 4 is clamped and fixed between the relatively pressed gear teeth 31 and the wheel groove 21, and the clamping is firm and reliable. At this time, it is not easy to escape from the screen window slideway under the action of a certain external force. In the screen window slideway in this embodiment, multiple pairs of paired toothed wheels and groove wheels are provided to clamp and fix the window screen together.
[0034] The window screen clamping part 41 in this embodiment is thickened by using a strip of polyurethane film. The polyurethane film is used to be arranged on the window screen clamping part, so that the window screen clamping part is stronger and has a certain hardness and toughness, which is conducive to the clamping of the clamping wheel. In addition, the polyurethane film has a certain bending resistance and is durable.
[0035] You can also optimize the solution, such as setting the window screen to Figure 5 As shown, a row of square holes 42 are provided on the clamping portion 41 of the window screen 4, and the row of square holes 42 mesh with the gear teeth 31 of the second clamping wheel. A row of square holes 42 mesh with the toothed wheel, so that the gear teeth 31 of the toothed wheel pass through the square holes 42, thereby hanging the window screen 4 on the gear teeth of the toothed wheel. Such a window screen will only fall off when the gear teeth are damaged, so the window screen is less likely to fall off when subjected to external forces such as wind.
[0036] Example 3
[0037] This embodiment provides a screen window. Figure 6 Schematic diagram of the clamping state of the window screen in the window screen slideway in this embodiment. Figure 6 As shown, the difference between this embodiment and implementation 1 is that the pair of clamping wheels in this embodiment is a first clamping wheel 2 and a second clamping wheel 3; the first clamping wheel 2 is a step wheel (the step wheel is a wheel in which a large diameter wheel and a small diameter wheel are coaxially connected as one, wherein the cylindrical surface of the large diameter wheel is called the first wheel surface, the cylindrical surface of the small diameter wheel is called the second wheel surface, and the plane of the cylinder of the large diameter wheel where the first wheel surface and the second wheel surface are connected is called the step surface), and the first wheel surface 22 and the second wheel surface 23 of the first clamping wheel 2 are both cylindrical surfaces. The second clamping wheel 3 is a cylindrical wheel, the small cylindrical wheel surface (i.e., the second wheel surface 23) of the first clamping wheel 2 is clamped with the wheel surface of the second clamping wheel 3, and the step surface 24 of the first clamping wheel 2 is clamped with the top surface 32 of the second clamping wheel 3. The two edges of the window screen 4 are provided with window screen clamping parts 41. When installing the screen window, the window screen clamping part 41 of the window screen 4 is clamped between the step surface 24 of the first clamping wheel 2 and the top surface 32 of the second clamping wheel 3, and the second wheel surface 23 of the first clamping wheel 2 and the wheel surface of the second clamping wheel 3 are bent to make the reinforcing edge of the screen window bend 90 degrees and then clamped and installed on the screen window. Figure 7 FIG. 2 is a schematic diagram of the front view of the screen window in this embodiment. Figure 7 As shown, when the screen window is opened or closed, the window screen 4 is clamped and rotated by the first clamping wheel 2 and the second clamping wheel 3 so that the window screen 4 is unfolded or rolled up on the reel 5; and when the screen window is in normal use, the window screen 4 is bent, clamped and fixed between the relatively squeezed first clamping wheel 2 and the second clamping wheel 3. The bending makes it more difficult for the window screen to fall off from between the first clamping wheel 2 and the second clamping wheel 3, and it is more firm and reliable. At this time, it is more difficult to fall off from the screen window slide under the action of a certain external force.
[0038] Example 4
[0039] This embodiment provides a screen window, and the difference between this embodiment and embodiment 1 is that the pair of clamping wheels is a pair of gears meshing with each other. When the pair of clamping wheels is a pair of gears meshing with each other, the window screen is clamped between the pair of gears, and when the screen window is opened or closed, the window screen is clamped between the meshing teeth of the two gears, and the window screen is unfolded or rolled up on the reel by the rotation of the two gears. When the screen window is in normal use, the window screen is clamped and fixed between the meshing teeth of the two clamping gears, and the clamping is firm and reliable. At this time, the window screen is not easy to fall out of the screen window slideway under the action of a certain external force.
[0040] It can be seen from the above-mentioned embodiments that the clamping wheels that are arranged in pairs to squeeze and press each other can be smooth wheels, or at least one of them can be a toothed wheel, and of course it can also be two toothed wheels. Those skilled in the art will know that as long as clamping wheels are provided to squeeze and clamp the window screen, the clamping effect of the window screen in the prior art will be improved, so that the window screen will not easily fall out of the window screen slide, and mosquitoes can be prevented from entering due to gaps formed by the window screen falling out.
[0041] It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other. In addition, the above are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.
