Description

Screen automatic installer for screen door and screen window

The present invention relates to a gauze installer, especially an automatic gauze installer for screen doors and screen windows.

Press, Taiwan is located in the subtropical zone, and the warm climate is very suitable for mosquitoes to grow. After all kinds of mosquitoes breed and roam around and bite the human body, it is easy to infect the bacteria attached to the mosquitoes and cause diseases. Among the many methods to prevent mosquitoes from invading the human living environment, the safest, most environmentally friendly, durable and economical is to set up screen meshes on doors and windows to form screen doors or screen windows, and use the screen mesh to interlace tiny meshes to prevent mosquitoes from entering human activities. range, while ensuring air circulation.

Generally, screen doors and screen windows are composed of a frame and a gauze. The frame is mainly used to support the gauze. The gauze is installed to the frame through a tedious process. In order to install the gauze, there is an installation slot on the frame. When installing the gauze , Lay the gauze on the frame, and use the beading roller to press the bead and the edge of the gauze into the installation groove of the frame, so that the gauze is combined with the frame.

However, in the above installation process, it is necessary to operate the bead rollers to roll back and forth, so that the bead and the edge of the gauze can be pressed into the installation groove of the frame, so the installation is time-consuming and laborious, the work efficiency is low, and the gauze is prone to slip during the installation process. The smaller the mesh, the easier it is for the gauze to slide and shift, so that the gauze cannot be flat after installation, which affects the appearance.

In view of the above-mentioned shortcomings of the conventional beading roller, the inventor of the present invention finally came up with the present invention after many discussions, trial production and sample tests, and many revisions and improvements.

The invention provides an automatic screen mesh installation device for screen doors and screen windows, comprising: a lower pressing piece, a lower pressing part is arranged at the lower end; two positioning pressing pieces are assembled on both sides of the lower pressing piece, the two positioning pressing pieces are connected with The lower pressing pieces can slide relatively up and down, the lower ends of the two positioning pressing pieces are provided with a pressing portion, and an accommodation space is formed between the pressing portions at the lower ends of the two positioning pressing pieces and the pressing portion at the lower end of the lower pressing piece; and A limiting means is used to limit the relative up and down sliding range of the two positioning pressing pieces and the lower pressing piece.

The main purpose of the automatic screen installation device for screen doors and screen windows of the present invention is that when it is used, the pressing parts of the two positioning pressing pieces can be used to press the positioning screen net, and then the lower pressing part of the lower pressing piece can press the bar together with the screen net. The edge is pressed into the installation slot of the frame and fixed, which saves time and effort in the installation of the gauze, and improves the work efficiency.

The second purpose of the automatic screen mesh installation device for screen doors and screen windows of the present invention is that the installation process can prevent the screen mesh from sliding and shifting, so that the screen mesh can be flat after installation and ensure beautiful appearance.

The following descriptions are further described below in conjunction with the drawings of the preferred embodiments of the present invention, in order to enable those who are familiar with the related art of the present invention to implement according to the statements in this specification.

First of all, please refer to the first to fourth figures, it is an automatic screen installation device for screen doors and screen windows of the present invention. The installation device 1 includes: a first pressing piece 10, two positioning pressing pieces 20, an elastic The unit 30 and a limiting means.

The lower pressing member 10 is in the shape of a horizontally upright long sheet, the lower end is provided with a lower pressing portion 11 , and the upper end is provided with an operating portion 12 .

The two positioning pressure pieces 20 are assembled on both sides of the lower pressure piece 10 , and the two positioning pressure pieces 20 and the lower pressure piece 10 can slide up and down relative to each other. The pressing portion 21 is provided with an embedded groove 211 , and an elastic protective strip 212 is embedded in the embedded groove 211 . The protective strip 212 protrudes downwards partially outside the embedded groove 211 in normal state. The two positioning pressures An accommodating space S1 is formed between the pressing portion 21 at the lower end of the pressing member 20 and the pressing portion 11 at the lower end of the pressing member 10 .

The abutting unit 30 is disposed between the pressing member 10 and the two positioning pressing members 20, and is used for bouncing the two positioning pressing members 20 downward. One end of the four-axis column 31 is inserted and fixed on both sides of the upper ends of the two positioning pressing pieces 20 respectively. The other end of the column 31 is slidably arranged, and the four springs 32 are respectively sleeved on the outer edge of the four-axis column 31 and spring against the operating portion 12 of the lower pressing member 10 and the upper ends of the two positioning pressing members 20 .

The limiting means is that the lower pressing piece 10 is provided with two rows of longitudinally arranged plural perforations 13 (the perforations 13 are screw holes in this embodiment), and the two positioning pressing pieces 20 are provided with two longitudinally arranged pluralities The elongated hole 22 is matched with a plurality of limiting members 40 to penetrate through the plurality of through holes 13 of the lower pressing member 10 and the plurality of elongated holes 22 of the two positioning pressing members 20 (the limiting member 40 is a bolt in this embodiment. With a nut), the plurality of limiting members 40 are combined with the plurality of through holes 13 of the lower pressing member 10, and both ends of the plurality of limiting members 40 are slidably sleeved in the plurality of elongated holes of the two positioning pressing members 20. 22, so that the two positioning pressing pieces 20 and the lower pressing piece 10 can slide relatively up and down, and limit the range that the two positioning pressing pieces 20 and the lower pressing piece 10 can slide relatively up and down.

When the gauze 60 is installed on the frame 50, as shown in Figs. 5 to 7, the frame 50 is provided with an installation surface 51, and the installation surface 51 is provided with a rectangular installation groove 511, and the gauze 60 is laid on the frame 50. On the mounting surface 51 of the frame 50, place a bead 70 on the screen 60 and align with the mounting groove 511 of the frame 50, and use the lower ends of the two positioning pressing pieces 20 of the mounting device 1 to abut against the pressing portion 21. The protective strip 212 presses the gauze 60 to position the gauze 60, and at the same time, the pressing strip 70 is accommodated in the accommodating space S1 and located below the lower pressing portion 11 of the lower pressing member 10. As shown in Figure 8 and Figure 9, the lower pressing member 10 is operated by the operating portion 12 of the lower pressing member 10 to be pressed and displaced relative to the two positioning pressing members 20, and the pressing portion 11 of the lower pressing member 10 is used to press the bar. 70 together with the edge of the gauze 60 is pressed into the installation groove 511 of the frame 50 to be fastened, so that the gauze 60 is combined with the frame 50. At this time, the springs 32 are in a compressed state, as shown in Figure 10, Lift the installer 1 upwards, so that the lower pressing portion 11 of the lower pressing member 10 is separated from the pressing bar 70, the protection bars 212 of the pressing portions 21 at the lower ends of the two positioning pressing members 20 are separated from the gauze 60, and the two positioning pressing members 20 are separated from the gauze 60. The component 20 is restored to its original position by the elastic force of the springs 32 to complete the installation.
