Problems solved by technology
The above-mentioned profile connection lock can complete the connection between the profiles, and can complete the connection and disassembly of the profiles without using additional tools, but the pressing block of the profile connection lock is easy to fall off, and the positioning is unstable, especially in the profile When the connecting lock is not inserted into the groove of the profile, the pressing block is not fully positioned. At this time, the pressing block can slide away from the main body through the gaps on the left and right sides of the main body that communicate with the T-shaped groove, that is, the pressing block will automatically fall off.

Embodiment Construction
[0041] Such as Figure 1 to Figure 18As shown, a profile connection lock includes a main body 1, a pressure block 2 and a cam member. The main body 1 has opposite front sides 11 and rear sides 12. A slide groove 13 is provided on the main body 1. The front side 11 is provided with a front notch 131 communicating with the chute 13, the pressure block 2 is slidably placed in the chute 13 and guided by the chute 13, the cam member is pivotally mounted on the main body 1, The pressure block 2 slides along the sliding groove 13 under the push of the cam member and can partially protrude from the front side 11 of the main body;
[0042] The pressing block 2 is provided with a strip-shaped limiting groove 21, and the length direction of the limiting groove 21 is parallel to the length direction of the chute 13; the limiting groove 21 can be in the shape of a racetrack. In this embodiment, the number of pressing blocks on the main body can be one, two, three, etc., and each pressing ...

The invention relates to a sectional material connecting lock which is mainly used for connecting two or more sectional materials. The sectional material connecting lock comprises a body, a pressing block and a cam piece. The body is provided with a front side and a rear side opposite to the front side. The body is provided with a sliding groove. The front side of the body is provided with a front notch communicated with the sliding groove. The pressing block can be arranged in the sliding groove in a sliding mode and is guided by the sliding groove. The cam piece is pivoted to the body. The pressing block slides along the sliding groove under the push of the cam piece and can locally extend out of the front side of the body. The pressing block is provided with a limiting groove. The body is provided with a limiting pin capable of sliding in the limiting groove in the pressing block. The limiting groove is provided with a first end and a second end opposite to the first end. The pressing block slides in the sliding groove and is limited when the limiting pin abuts against the first end or the second end. Due to the fact that the sliding groove and the limiting pin are used for positioning the pressing block, the pressing block can stably slide in the sliding groove and will not be automatically disengaged or slide away from the body, and the sectional material connecting lock is simple in structure.
Description
technical field [0001] The invention relates to a profile connection lock, which is mainly used for connecting two or more profiles. Background technique [0002] Profiles are often used in display equipment, and profiles need to be connected. For example, the Chinese Utility Model Patent Specification CN203374585U discloses a profile quick-connect lock (i.e., a profile connection lock), which includes a main body, two pressing blocks and two cam parts, and the upper and lower parts of the front half of the main body are respectively provided with penetrating left and right sides. Inverted T-shaped slots, the second half of the main body corresponds to two inverted T-shaped slots, each with a square hole and a channel communicating with the square hole and the end face of the main body on the same side, the pressing block is inverted T-shaped, and the bottom of the pressing block is set There is an arc-shaped concave area, and the pressing block is inserted into the inverte...
