DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Please refer to 1-3. An embodiment of the present invention is provided: a double-pin pressing groove and pin assembly assembly, including a bottom positioning component 1, an upper positioning component 2 and a positioning block 3. The bottom of the profile is placed above the bottom positioning component 1, and the upper positioning component 2 is located above the profile. The bottom positioning component 1 includes a bottom positioning block 11, and the bottom positioning block 11 is provided with a waist-shaped long hole 12. The waist-shaped long hole 12 is plugged with a base cylindrical pin 13. The waist-shaped long hole 12 allows the base cylindrical pin 13 to have a certain tilting space, which is convenient for profile adjustment. The upper positioning component 2 includes a double-cone pressing block 21. When installing, as shown in FIG. Figure 2The bottom surface of the double-cone tightening block 21 shown is facing upward, and a double-pin limit block 22 is provided above the double-cone tightening block 21. The double-cone pin 23 is inserted into the double-cone tightening block 21 and the double-pin limit block 22. The double-cone pin 23 passes through the double-pin limit block 22 and passes through one side of the double-cone tightening block 21. The double-cone tightening block 21 and the double-pin limit block 22 are connected by a hexagon socket head screw 24. The hexagon socket head screw 24 can be fixed by rotating and locking the distance between the double-cone tightening block 21 and the double-pin limit block 22. In this way, when the cross-section of the profile is directly against the ground or wall, an extended hexagonal plate can be used. The hand goes deep into the profile groove to lock it. A cylindrical pin 26 and a spring 25 are provided between the double-cone tightening block 21 and the double-pin limit block 22. The cylindrical pin 26 plays a guiding role to ensure that the double-cone tightening block 21 and the double-pin limit block 22 can only move in the upward and downward directions, and the spring 25 provides elastic force to expand the distance between the double-cone tightening block 21 and the double-pin limit block 22 to facilitate the movement and adjustment of the double-cone pin 23. The guide pin 27 is inserted into the side of the double-pin limit block 22. The guide pin 27 makes the double-cone pin 23 only move laterally. The bottom positioning component 1 is located at the bottom surface of the aluminum profile, and the upper positioning component 2 is located at the upper end of the aluminum profile.

[0019] The upper and lower ends of the base cylindrical pin 13 and the double-taper pin 23 are both conical structures. The conical structure allows the base cylindrical pin 13 and the double-taper pin 23 to have a certain inclination, which makes it easier to move when adjusting the aluminum profile. A T-shaped limit block is provided at the bottom of the bottom positioning block 11, so that the profile is parallel after the base cylindrical pin 13 is brought close.

[0020] A guide groove is provided on the double-taper pin 23 , and the guide pin 27 is slidably connected to the guide groove, so as to limit the moving direction of the double-taper pin 23 .

[0021] There are two cylindrical pins 26 and two springs 25 , and the cylindrical pins 26 and the springs 25 are set diagonally. The diagonal setting can ensure uniform force. A movable hole is provided on the double-pin limit block 22 to facilitate adjustment of the double-taper pin 23.

[0022] Working principle: When in use, first place the bottom positioning component 1 horizontally on the installation surface, and then stretch the base cylindrical pin 13 outward. After completion, the two profiles are respectively installed in the positioning blocks 3 and placed on the base cylindrical pin 13, so that the two base cylindrical pins 13 are respectively inserted into the two profiles with positioning blocks 3, so that the two profiles squeeze the base cylindrical pin 13 to fix the gap below the profile. Then, the double-cone pin 23 of the upper positioning component 2 is plugged in above the two profiles. At this time, since there is a groove forming a channel on the double-cone tightening block 21 and the double-pin limit block 22, the top of the two profiles are fixed. During insertion, since the top of the profile is fixed, the base cylindrical pin 13 below is squeezed by the profile and moves toward the center. After completing the installation of the upper positioning component 2, the hexagonal socket head screw 24 can be rotated with an extended hexagonal wrench to retract the double-cone tightening block 21 and the double-pin limit block 22 to achieve locking.
