DETAILED DESCRIPTION

[0023] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0024] See also Figure 6 The existing aluminum alloy profile (hereinafter referred to as aluminum profile 5) is a widely used building material, which is used to manufacture various furniture, display racks, flag stands, equipment housings, mechanical equipment stands, etc. One of the functions of the slot 51 of the aluminum profile 5 is to connect multiple profiles, which can be matched with different accessories for connection, and can be combined into profiles of different shapes, sizes and uses. The main function of this application is to connect two aluminum profiles 5.

[0025] Specific embodiment 1: Please refer to Figure 1-5 An aluminum profile connecting frame, comprising:

[0026] Angle bracket 1, the angle bracket 1 is a right-angle bucket-shaped structure formed by two straight plates 11 and two triangular plates 12. Specifically, the two straight plates 11 are arranged perpendicular to each other, and the two triangular plates 12 are arranged facing each other. Two slots 13 are opened on the end of the angle bracket 1;

[0027] The rear cover 2 is arranged on the port of the angle frame 1 to close the internal space of the angle frame 1; in order to connect and fix the rear cover 2 with the angle frame 1, two protruding inserts 21 are arranged on the body of the rear cover 2, and the inserts 21 and the slots 13 cooperate with each other and correspond one to one. After the rear cover 2 is arranged on the angle frame 1, the inserts 21 are embedded in the slots 13, and the rear cover 2 and the angle frame 1 are connected and fixed by interference connection;

[0028] In other embodiments, the connection and fixation between the rear cover 2 and the corner bracket 1 can also be achieved by other methods, for example, a magnetic block with opposite magnetic poles can be arranged between the rear cover 2 and the corner bracket 1 by magnetic attraction so that the rear cover 2 and the corner bracket 1 are connected and fixed, or the rear cover 2 and the corner bracket 1 can be connected and fixed by threading.

[0029] Furthermore, a receiving groove 22 is provided on one end of the rear cover 2 facing the inner space of the angle frame 1;

[0030] Internal screwdriver 4, see Figure 4, the inner angle screwdriver 4 is arranged in the accommodating groove 22; specifically, the inner angle screwdriver 4 includes a cutter head 41, a connecting rod 42 and a pin 43, the cutter head 41 is fixedly arranged at the head end of the connecting rod 42, and the pin 43 is fixedly arranged at the tail end of the connecting rod 42; the tail end of the connecting rod 42 is hinged to the rear cover 2 through the pin 43, and under the drive of external force, the cutter head 41 and the connecting rod 42 can be turned up and down relative to the rear cover 2 around the axis of the pin 43. Through such a setting, the inner angle screwdriver 4 can be stored in the accommodating groove 22 in a folded manner, and the inner angle screwdriver 4 can be turned out when in use;

[0031] The connecting member 3 has two connecting members 3, and the two connecting members 3 are arranged corresponding to the two straight plates 11, and are used to connect the two aluminum profiles 5; specifically, the connecting member 3 is composed of an internal angle bolt 31 and a clamping block 32, wherein the screw of the internal angle bolt 31 passes through the straight plate 11 at the corresponding position and is threadedly connected with the clamping block 32. When in use, the clamping block 32 is arranged in the clamping groove 51 of the aluminum profile 5 at the corresponding position. Rotating the internal angle bolt 31 can make the clamping block 32 press the aluminum profile 5 to fix it to the connecting frame.

[0032] In this embodiment, the model of the cutter head 41 is compatible with the model of the internal angle bolt 31. When in use, the internal angle screwdriver 4 can be turned out, and the cutter head 41 can be used to tighten or loosen the internal angle bolt 31. There is no need to prepare installation tools of corresponding models, which makes the connection and fixation between aluminum profiles more convenient, time-saving and labor-saving; in other preferred implementation schemes, the cutter head 41 can be threadedly connected to the head end of the connecting rod 42, and the model of the cutter head 41 can be adjusted according to the model of the internal angle bolt 31 installed on the angle frame 1, thereby improving the practicality of the present connecting frame.

[0033] It should be noted that the back cover 2 is arranged on the port of the angle bracket 1 to seal the internal space of the angle bracket 1. On the one hand, it can prevent dust or moisture from entering and corroding the internal angle bolts 31, thereby increasing the service life of the connecting frame; on the other hand, the internal angle screwdriver 4 can be stored in the internal space of the angle bracket 1 to ensure the working performance of the internal angle screwdriver 4.

[0034] Through the technical solution, a movable internal angle screwdriver is provided in the space between the angle bracket and the back cover, and the model of the internal angle screwdriver corresponds to the model of the internal angle bolt of the connecting piece. When in use, there is no need to prepare installation tools of the model corresponding to the model of the internal angle bolt, thereby making the connection and fixation between aluminum profiles more convenient, time-saving and labor-saving.
