Description

Technical Field

[0001] The invention relates to an aluminum profile connection and assembly structure, which is used for connecting various aluminum alloy cabinets, racks and table structures. Background Art

[0002] At present, the connection between the columns and beams and longitudinal beams of aluminum alloy lockers generally adopts a lock-type structure, such as Figure 9 、 Figure 10 、 Figure 11 As shown, the elliptical lock cap end of the lock pin at one end of the lock-type structure is inserted into the elliptical hole on the connecting surface of the cabinet column and rotated 90 degrees. The elliptical lock cap is clamped in the elliptical hole of the cabinet column. The other end of the lock-type structure is inserted into the cavity of the beam and tightly fits with the cavity of the beam. The threaded top screw on the lock-type structure is exposed in the hole on the side of the beam. By rotating the top screw, the top screw enters the V-shaped notch of the lock pin, causing the lock pin with the V-shaped notch to undergo axial displacement to fix and lock the column and the beam.

[0003] Its shortcomings are:

[0004] 1. In actual application, after the top screw is tightened, the lock pin is prone to rotation due to the axial tension, causing the lock to loosen. 2. Because the axial displacement of the lock pin is fixed, any deviation when processing the top screw fixing hole in the aluminum profile will cause the lock pin to not return to its original position, resulting in the column and beam not being locked. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an aluminum profile connection assembly structure, through which the connection between the columns of the aluminum alloy locker cabinet and the crossbeams and longitudinal beams is achieved, and the loosening phenomenon will not occur after the structure is tightened.

[0006] The technical solution adopted by the present invention is: an aluminum profile connection assembly structure, including cabinet columns, cabinet beams, cabinet longitudinal beams, and also includes plastic plug-in blocks, hexagon socket screws, decorative hole covers and separable plastic tensioning blocks;

[0007] The separate plastic expansion block is composed of an expansion block I and an expansion block II which are connected as one;

[0008] Fold the tensioning block I and the tensioning block II together, and connect a section of the semicircular groove I of the tensioning block I with a section of the semicircular groove II of the tensioning block II to form a circular hole;

[0009] Insert the short protruding end of the separate plastic tensioning block into the cabinet crossbeam cavity II, so that the end surface of the circular hole of the separate plastic tensioning block is flush with the end surface of the cabinet crossbeam;

[0010] Insert the ends of the hexagon socket screws into the large hole on the outer column surface at the upper end of the cabinet column, the small hole on the inner column surface, and screw them together with a circular hole of the detachable plastic tensioning block. Turn the hexagon socket screw clockwise, and the hexagon socket screw moves forward in the circular hole to expand the tensioning blocks I and II. The long raised strips I and short raised strips I of the tensioning block I and the long raised strips II and short raised strips II of the tensioning block II are respectively tightened with the upper and lower surfaces of the cabinet beam cavity II. The nut surface of the hexagon socket screw fits with the small hole surface on the inner column surface of the cabinet column to connect the cabinet column and the cabinet beam together. Install the decorative hole cover on the large hole on the outer column surface of the cabinet column.

[0011] Insert the four raised wall ends of the plastic plug-in block into the cabinet longitudinal beam cavity III, and use a wooden hammer to knock the end surface of the large plug-in block of the plastic plug-in block until the raised wall between the large plug-in block and the middle plug-in block is completely in contact with the cabinet longitudinal beam cavity III, so that the four raised walls are tightened against the four sides of cavity III, and the plastic plug-in block is fixed to the cabinet longitudinal beam;

[0012] Place the large plastic plug-in block above the cabinet column cavity I, with the bent edge of the cabinet column corresponding to the toothed notch of the plastic plug-in block. Use a wooden hammer to knock the plastic plug-in block downward to place the large plastic plug-in block in the cabinet column cavity I, and insert the bent edge of the cabinet column into the toothed notch of the plastic plug-in block until the upper end surface of the cabinet column is flush with the top surface of the cabinet longitudinal beam, so that the cabinet longitudinal beam and the cabinet column are connected together.

[0013] The beneficial effects of the present invention are:

[0014] 1) Using the aluminum alloy profile structure, the plastic tensioning block is placed in the beam, and the screws are screwed into the plastic tensioning block through the column, so that the tensioning block is separated and deformed, and then tightened in the aluminum alloy cavity to achieve the fastening of the beam and the column. It is easy to install. According to tests, a single tensioning block can withstand a tensile force of not less than 25 kg.

[0015] 2) Connect the two ends of the plastic plug-in block to the cabinet column and the cabinet longitudinal beam to form a right-angle fastening structure, and then tighten the connection.

[0016] 3) Through the above two steps, the three-dimensional structure of the cabinet can be realized quickly and easily, and the structure will not become loose after being tightened. BRIEF DESCRIPTION OF THE DRAWINGS
