Anti-skid profile corner brace device locked by expansion force

Abstract

The invention relates to an anti-skid profile corner brace device locked by expansion force. The device comprises two hollow corner profile bodies, screws and connecting pins, wherein reinforcing ribsor reinforcing blocks are arranged in cavities at two ends of the hollow corner profile bodies correspondingly, expansion screw holes are arranged between the reinforcing ribs or the reinforcing blocks correspondingly, apertures of the expansion screw holes are smaller than diameters of the screws so as to achieve a purpose of expansion, pin holes are further formed in the cavities of the hollowcorner profile bodies correspondingly, the connecting pins are sleeved with the pin holes in a penetrating mode so as to connect the two hollow corner profile bodies, and anti-skidding insections arefurther arranged on sections of the outer side ends of the two hollow corner profile bodies correspondingly. Expansion locking force of a corner brace is firmer, a loosening phenomenon is avoided, a glue injection process is omitted, a corner assembling process is simplified, the assembling efficiency is improved, no formaldehyde and methylbenzene pollutants are generated, and a safe, environmentally friendly and efficient effect is achieved.

Description

technical field [0001] The invention relates to the field of a corner code mechanism used for the corner assembly and connection of aluminum profiles and aluminum profiles, in particular to a corner code mechanism that relies on expansion force for fixing. Background technique [0002] The door and window corner code is the key component of the corner connection of the aluminum alloy door and window frame, which ensures the strength and flatness of the corner of the door and window frame. The Chinese patent number is CN201410374377.3, and the patent literature titled "a compound corner code for profile group corners" discloses a composite corner code scheme, which includes a symmetrically arranged first corner code body and a second corner code body, The first corner code body and the second corner code body are spliced ​​and set together, and a screw hole is respectively provided on the upper surface between the two ends of the first corner code body and the second corner c...

AI Technical Summary

Problems solved by technology

[0003] In practice, the above-mentioned expansion-type fixed corner code mechanism has been found to have the following disadvantages: (1) It needs to be provided with multiple glue injection grooves on the first corner code body and the second corner code body respectively As a result, it must be processed by mold opening die-casting. When aluminum alloy profiles of different specifications are used, they must be molded and processed according to the model specifications, resulting in a large number of molds, high mold opening costs, and high processing and production costs; (2 ) It needs the help of glue injection and bonding to ensure the firmness of its locking connection, which adds to the complexity and cumbersomeness of assembly and operation, the assembly efficiency is low, and it is easy to cause the formaldehyde and toluene of door and window products to exceed the standard, affecting people's home environment and environment. healthy
