[0025] Embodiment

[0026] Please refer to Figures 1-4 As shown, a technical solution for an aluminum profile connection structure provided by the present utility model: An aluminum profile connection structure includes a bidirectional screw 1. Threaded portions at both ends of the bidirectional screw 1 are connected with movable plates 2. Upper and lower ends of the movable plates 2 are movably connected with a plurality of sliding wheels 3 through sliding holes opened. A positioning mechanism 4 and a resistance mechanism 5 are arranged on the movable plates 2. In this embodiment, the 40-series aluminum profile 8-4040A is taken as an example. When connecting, the two connection structures as a whole are placed into the groove bodies of the two bosses of the aluminum profile 9, and slide to a predetermined position through the sliding wheels 3. Then, the lower end of the groove body of the boss of another aluminum profile 9 is aligned with the sliding wheels 3 at the upper end of the connection structure as a whole and placed in. At this time, the upper and lower aluminum profiles 9 can move freely. During the movement process, the positioning mechanism 4 can fix the positions of the upper and lower sliding wheels 3, avoid the tangential force of the sliding wheels 3 when the two aluminum profiles 9 move, improve the sliding efficiency, and reduce wear. When moving to the required position, it can be locked through the resistance mechanism 5.

[0027] The positioning mechanism 4 includes a number of positioning wheels 401 and inlets and outlets 402. The positioning wheels 401 are respectively installed on the facing surfaces of the two movable plates 2, and the positioning wheels 401 on the two movable plates 2 are arranged in a staggered manner. The inlets and outlets 402 are respectively opened on the two movable plates 2, and the position of each inlet and outlet 402 corresponds to the movement path of the corresponding positioning wheel 401. During the sliding process, when the connection structure needs to be positioned, the operator first fixes the movable plate 2, and then simultaneously rotates the two bidirectional screws 1 located at the center of the plate body. At this time, the two movable plates 2 move in opposite directions, and the positioning wheels 401 extend out of the corresponding inlets and outlets 402 until the two positioning wheels 401 abut against the side surfaces of the boss grooves of the aluminum profile 9, so as to achieve the active positioning effect of the sliding wheel 3. The process of releasing the positioning is the reverse process of the above operation and will not be elaborated here.

[0028] The resistance mechanism 5 includes friction plates 501, and the friction plates 501 are respectively installed at both ends of the outside of the movable plate 2. In the specific implementation process, the friction plates 501 can be made of rubber materials. When the positions of the two aluminum profiles 9 are determined, the operator rotates the bidirectional screw 1 in the reverse direction (i.e., the direction opposite to the positioning tightening). At this time, the two positioning wheels 401 contract toward the inside of the inlets and outlets 402 and separate from the side surfaces of the boss grooves of the aluminum profile 9. As the bidirectional screw 1 continues to rotate, the two movable plates 2 displace outward. When the friction plates 501 on the plate surfaces abut against the side surfaces of the boss grooves of the aluminum profile 9, stop rotating. At this time, the entire connection structure will be in a relatively fixed state, so as to maintain the fixed connection state of the two aluminum profiles 9.

[0029] The side surface of the movable plate 2 is provided with a strengthening part 6. In the specific implementation process, threads matching the bidirectional screw 1 can be opened inside the strengthening part 6. By widening this connection part, the thread depth can be increased, the thread engagement stability can be improved, and the loosening risk can be reduced.

[0030] The end of the bidirectional screw 1 is connected with a locking nut 7, and the locking nut 7 is located outside the strengthening part 6. After the resistance mechanism 5 completes the position limitation of the two aluminum profiles 9, a locking nut 7 can be added to one end of the bidirectional screw 1. By rotating the locking nut 7, the side surface of the locking nut 7 abuts against the strengthening part 6 of the movable plate 2 to prevent the resistance mechanism 5 from loosening under external force.

[0031] The surfaces of the locking nut 7 and / or the strengthening part 6 on the side of the movable plate 2 have a rubber layer 8. This design can further improve the fastening force between the locking nut 7 and the strengthening part 6 of the movable plate 2 and avoid loosening in a vibrating environment.

[0032] The working principle of the present utility model is as follows:

[0033] When the aluminum profile connection structure of this embodiment is in use, first, the operator aligns the boss grooves of the two aluminum profiles 9 with the sliding wheels 3 of the connection structure respectively and slides them to the predetermined positions. During the sliding process, the positioning wheels 401 inside the positioning mechanism 4 slide along the side surfaces of the boss grooves of the aluminum profiles 9, thereby achieving precise positioning of the sliding wheels 3, preventing the sliding wheels 3 from being affected by tangential forces, improving the sliding efficiency of the overall structure, and reducing the wear of the components.

[0034] After the two aluminum profiles 9 are moved to the predetermined positions, the operator reversely rotates the bidirectional screw 1 to gradually move the movable plate 2 outward until the friction plate 501 is in close contact with the side surface of the boss groove of the aluminum profile 9. At this time, the positioning wheels 401 retract, and the positions of the two aluminum profiles 9 are firmly fixed to ensure the stability of the connection structure during use.

[0035] Finally, the operator installs a locking nut 7 at one end of the bidirectional screw 1 and tightens it to the strengthening part 6 of the movable plate 2 to reduce the risk of the connection structure loosening under vibration or external forces.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
