Description

Technical Field

[0001] The present invention relates to the field of building materials, and in particular to a louver corner code and a louver corner assembly. Background Art

[0002] With the development of the current construction industry, blinds are widely used as good packaging and decorative building materials. When in use, blinds often need to be installed and fixed on walls or other buildings of various shapes. For example, when blinds are used to close a wall, a column is usually set up at the corner, and the blinds are fixed to the column to achieve the connection at the blind corner, forming a blind protection frame. However, with the influence of external environmental factors during long-term use, the blinds will show different degrees of aging and damage. When replacement is needed, since the blinds are fixed to the column, it is inconvenient to disassemble. Therefore, the entire blind needs to be replaced together with the column. The replacement operation is complicated and costly. Summary of the Invention

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See Figure 1 and Figure 2 , a blind corner assembly 999 provided in one embodiment of the present invention. The blind corner assembly 999 includes two blind frame bars 800 and a blind corner bracket 900 provided in one embodiment of the present invention. The blind corner bracket 900 is used to clamp and fix the two blind frame bars 800 at the corner.

[0023] See Figure 1 and Figure 2 The two louver bars 800 include a first louver bar 801 and a second louver bar 802. Both the first louver bar 801 and the second louver bar 802 are elongated strips with uniform cross-sections. Each of the first louver bar 801 and the second louver bar 802 includes a snap-on portion 820 and an externally visible portion 840. The snap-on portion 820 is fixedly connected to the inner side of the externally visible portion 840. The externally visible portion 840 is a vertically symmetrical structure with the snap-on portion 820 as the axis. The snap-on portion 820 is inserted into the louver corner bracket 900 along the extension direction of the louver bar 800. The externally visible portion 840 is disposed on the inner side 910 of the louver corner bracket 900. The upper side 821 of the snap-on portion 820 is provided with two parallel upper snap-on slots 822 extending in the extension direction. The lower side 823 of the snap-on portion 820 is provided with two parallel lower snap-on slots 824 extending in the extension direction. In this embodiment, the number of the louver frame bars 800 is two. In other embodiments, the number of the louver frame bars 800 may also be three or more.
