[0002] Aluminum plate refers to a rectangular plate made by rolling aluminum ingots. It is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium and thick aluminum plate, patterned aluminum plate, etc. Aluminum plate not only retains the main characteristics of the original component materials (aluminum alloy plate, non-metallic polyethylene plastic), but also overcomes the shortcomings of the original component materials, and thus obtains many excellent material properties: high strength, corrosion resistance, fire resistance, moisture resistance, sound insulation, heat insulation, shock resistance, light weight, easy processing and molding, and can be recycled repeatedly. It is widely used in the decoration of curtain walls, interior and exterior walls, foyers, hotels, shops, conference rooms, etc., and in the production of aluminum furniture, etc.

[0023] In order to make the technical means, technical features, purpose of the utility model and technical effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Example 1

[0025] like Figure 1-Figure 4 As shown, a connection structure of an aluminum plate includes a connection base 1 and a connection base 2. The connection base 2 is connected to the connection base 1 in a detachable manner. Specifically, the connection base 2 can be connected to the four side walls of the connection base 1. After connection, the plate can be installed and connected in the horizontal direction and / or vertical direction.

[0026] like Figure 1 and Figure 2 As shown, the four side walls of the connection base 1 are all processed with plug-in grooves 3, and the lower surface of the connection base 1 is processed with four connection countersunk holes 4. The four connection holes are respectively adapted to the plug-in grooves 3 on the four side walls. The connection countersunk holes 4 include a large diameter hole 41 and a small diameter hole 42. The large diameter hole 41 and the small diameter hole 42 are coaxially processed. A connecting pin 5 is installed in the small diameter hole 42. The connecting pin 5 can slide and retract in the small diameter hole 42. The upper end of the connecting pin 5 passes through the small diameter hole 42 and extends into the plug-in groove 3. An adjusting nut 7 is installed at the end of 41 away from the small diameter hole 42, and the adjusting nut 7 is threadedly connected to the large diameter hole 41. An elastic member 6 is installed in the large diameter hole 41, and the elastic member 6 is located between the adjusting nut 7 and the connecting pin 5. In this embodiment, the elastic member 6 is a spring, one end of the spring abuts on the adjusting nut 7, and the other end of the spring abuts on the connecting pin 5. The spring pushes the connecting pin 5 to extend into the plug-in slot 3, and the connecting pin 5 extends to the upper end of the plug-in slot 3 and is processed into an arc shape or a chamfered form.

[0027] like Figure 4As shown, a plug-in block 8 is integrally processed on the side surface of one end and / or both ends in the length direction of the connecting seat 2. The plug-in block 8 is adapted to the plug-in slot 3. The plug-in block 8 can be inserted and installed in the plug-in slot 3. A plug-in hole 9 is processed on the plug-in block 8, and the plug-in hole 9 passes through the plug-in block 8. When the plug-in block 8 is inserted and installed in the plug-in slot 3, the connecting pin 5 is correspondingly inserted and connected in the plug-in hole 9, so that the connection and fixation of the connecting seat 2 on the connecting base 1 are realized. In order to facilitate the insertion and connection of the plug-in block 8 into the plug-in slot 3, the lower surface of the end of the plug-in block 8 away from the connecting seat 2 is processed into an arc shape or chamfered structure. During the insertion process, the arc or chamfer of the plug-in block 8 contacts and squeezes with the arc or chamfer of the connecting pin 5, and the elastic The spring is squeezed and retracts relative to the small diameter hole 42, so that the plug-in block 8 can be inserted into the plug-in slot 3. After being inserted into place, the plug-in hole 9 corresponds to the coaxial center of the connecting pin 5. The connecting pin 5 is extended again under the action of the spring and inserted into the plug-in hole 9. A fixing groove 10 is processed on the upper surface of the connecting seat 2 throughout its length direction for the plug-in installation of the plate. In order to improve the stability of the plate connection, a fastener is processed on the connecting seat 2. In this embodiment, the fastener is an elastic clip 11. There are two elastic clips 11. The two elastic clips 11 are respectively connected to the side walls of the fixing slot 10. The plate is installed in the fixing slot 10, and the elastic clips 11 on both sides are squeezed to generate deformation elastic force to clamp the plate.

[0028] like Figure 1-Figure 3 As shown, a cross groove 14 is processed on the upper surface of the connecting base 1, and the cross groove 14 corresponds to the fixing groove 10, which is convenient for the cross-connection installation of the plate. The cross groove 14 structure can meet the cross-connection requirements when the plate is installed horizontally and vertically.

[0029] like Figure 3 As shown, an unlocking hole 15 is processed on the bottom plane of the cross groove 14, and the unlocking hole 15 is adapted to the plug-in slot 3, that is, the number of unlocking holes 15 is processed into four. After processing, the unlocking hole 15 is coaxial with the connecting countersunk hole 4, and the diameter of the unlocking hole 15 is smaller than the diameter of the connecting pin 5. When it is necessary to release the connection of the connecting seat 2 on the connecting base 1, a tool is inserted into the unlocking hole 15 to push the connecting pin 5 to compress the elastic member 6, so that the connecting pin 5 retracts. Since the diameter of the unlocking hole 15 is smaller than the diameter of the connecting pin 5, there is a gap between the tool and the plug-in hole 9, and the connecting seat 2 can be pulled out a certain distance so that the plug-in block 8 blocks the connecting pin 5, thereby preventing the connecting pin 5 from rebounding after the tool is removed, thereby removing the connecting seat 2 from the connecting base 1.

[0030] During use, according to the needs of installing the aluminum plate, multiple connecting seats 2 are installed horizontally or vertically on the connecting base 1. When connecting, the plug-in block 8 of the connecting seat 2 is inserted into the plug-in slot 3 on the side wall of the connecting base 1. During the insertion process, the plug-in block 8 pushes the connecting pin 5 to compress the elastic member 6 to retract the connecting pin 5, which facilitates the insertion of the plug-in block 8. When the plug-in block 8 is inserted into the plug-in slot 3, the connecting pin 5 extends and resets under the action of the elastic member 6, and is correspondingly inserted into the plug-in hole 9 to realize the connection and fixation of the connecting seat 2 on the connecting base 1. The plate is inserted into the fixed groove 10 and the plate squeezes the elastic clamp 11 in the fixed groove 10. The elastic clamp 11 deforms and clamps the plate, clamps the plate, and realizes the connection of the plate.

[0031] Example 2

[0032] like Figure 5 As described above, the structure of this embodiment is basically the same as that of the first embodiment, the difference being that the fastener in this embodiment is a set screw 12. Specifically, a set hole 13 is processed on both side walls of the fixing groove 10. There are multiple set holes 13 on each side, and the multiple set holes 13 are evenly distributed to ensure a stable and balanced connection of the plate. The set screw 12 is threadedly connected in the set hole 13, and the plate is inserted and installed in the fixing groove 10. By screwing the set screw 12, the plate is fixedly connected to the fixing groove 10 to achieve the installation connection of the plate. The set screw 12 can be screwed from both sides or from one side at the same time to achieve fixation.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the technical scope of the present invention.
