Section bar connection device and section bar apparatus with the same

Abstract

The invention provides a profile connecting device and a profile device with the profile connecting device. The profile device comprises a first profile piece, a second profile piece and the profile connecting device connecting the first profile piece and the second profile piece; the profile connecting device comprises a left wing and a right wing which are provided with corresponding parts and connecting parts respectively connected with the first profile piece and the second profile piece; the corresponding parts are oppositely arranged, and the corresponding positions of the sides of the corresponding parts are provided with lug bosses mutually abutted; and each connecting part is connected with each corresponding part and positioned at one side of each lug boss, and the other side of the lug boss on the corresponding part is connected with a force application piece applying pressure to the corresponding part. The corresponding parts use the lug boss as the fulcrum after being pressed, the connecting parts press the first profile piece by utilizing the lever principle, profile connecting device is connected with the first profile piece by the connecting part on the profile connecting device, so that the stress area is increased, the tensile strength is ensured, and the firm connection between profiles is realized.

Description

technical field [0001] The invention relates to a profile connecting device and profile equipment using the profile connecting device. Background technique [0002] At present, most of the common profile connection methods on the market use L-shaped right-angled connection. The advantage of this connection method is that the installation speed is fast, but because one of the L-codes must be exposed outside, it destroys the overall appearance. The connecting parts are fastened by the straight connection between the self-tapping screw and the connecting code. Since the stress area of ​​the screw or pull nail is small, its pulling strength is insufficient, so that the connection is not firm enough. Another type of connection is the built-in U-code. This connection is also connected vertically with the profile with screws or pull rivets. Its defect is still that the pulling strength is insufficient, and the vertical and horizontal profiles are not firmly connected. Contents of...

[0002] At present, most of the common profile connection methods on the market use L-shaped right-angled connection. The advantage of this connection method is that the installation speed is fast, but because one of the L-codes must be exposed outside, it destroys the overall appearance. The connecting parts are fastened by the straight connection between the self-tapping screw and the connecting code. Due to the small stress area of ​​the screw or pull nail, the pulling strength is not enough, so the connection is not firm enough.

Another type of connection is the built-in U-code. This connection method is also connected to the profile with screws or pull nails. The defect is still that the pulling strength is insufficient, and the vertical and horizontal profiles are not connected firmly enough.
