Embodiment Construction

[0015] The accompanying drawings disclose the specific structure involved in an embodiment of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0016] As can be seen from Figure 1, the invention includes a profile 1 with a length equal to that of the bottom edge of the door. The notch of the profile 1 is equipped with a strip-shaped positioning bead 3 of the same length, and a dust-proof wall with the same length as the positioning bead 3 is inlaid on the bottom of the positioning bead 3. Sealing rubber strip 4.

[0017] It can be seen from Figure 2 that the section of the profile 1 is "∏" shape and the lower edge of the two side walls of the notch 5 has inner and outer flanging, and the notch 5 of the profile 1 is equipped with protruding edges 6 on both sides of the top. The positioning bead 3 of the profile 1 is provided with at least two spring seats 2 in the notch 5 of the p...

Abstract

The invention relates to a dustproof oriented door reed that includes section bar, which the section is n-shaped and the length is the same as hemline of the door. The rabbet of the section bar has bar oriented layering and at least two spring bases. The spring in the spring base is pressed on the top surface of the oriented layering. And on the bottom of the oriented layering, an axial through groove is set, and a dustproof sealed rubber strip that has the same length as the oriented layering is inlayed in the groove. The invention has compact structure and has the function of dustproof.

Description

technical field [0001] The invention relates to a door positioning device, in particular to a dust-proof positioning door spring. Background technique [0002] In order to prevent the opened door from being inadvertently closed by wind or other external forces, people generally set up magnetic door stoppers on the bottom corner of the door and the wall corresponding to the bottom corner when the door is opened to achieve positioning. This positioning method, although it can also prevent the room from The door is closed unintentionally, but there is only one positioning point, and it can only be fully opened, and other states cannot be realized. [0003] Unsealable door bottom seam is also one of the main channels for dust to enter the room. Lin Qinghai and Ding Guozhen applied for a utility model patent application named "Automatic Sealing Device for Door Bottom Seam" to the Chinese Patent Office on July 13, 1999, and granted the patent Right, the patent number is 99224434....
