Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a fastener for dry-hanging wall tiles. Background Art

[0002] In the existing dry-hanging implementation process of wall tiles, fasteners are commonly used. The fasteners include installation limit plates with installation holes and in an L-shaped structure, which are arranged in two groups and oppositely. Both installation limit plates are fixed on the installation plate, and a notch adapted to the keel is arranged between the two installation limit plates. The size of the notch of the above fasteners cannot be adjusted, so that it cannot adapt to the installation of keels with different widths. Therefore, this application provides a fastener for dry-hanging wall tiles to meet the requirements. Summary of the Utility Model

[0003] The purpose of this application is to provide a fastener for dry-hanging wall tiles, which is used to solve the technical problem that the size of the notch of the existing fastener cannot be adjusted, so that it cannot adapt to the installation of keels with different widths.

[0004] To achieve the above purpose, this application provides the following technical solution: A fastener for dry-hanging wall tiles includes an installation plate on which two installation limit plates in an L-shaped structure are arranged. A notch adapted to the keel is arranged between the two installation limit plates. The installation plate includes a first plate body and a second plate body. An insertion plate is installed at the right end of the first plate body, and a rectangular accommodating cavity adapted to the insertion plate is arranged at the left end of the second plate body. Limit strips are fixed at both ends of the insertion plate, and a U-shaped limit cavity adapted to the limit strips is arranged at the left end of the second plate body. The two installation limit plates are respectively installed on the first plate body and the second plate body.

[0005] As a preferred implementation manner in this embodiment, semi-circular elastic protrusions are arranged on the left sides of the two limit strips. The protruding end of the elastic protrusion extends beyond the outer plane end of the limit strip by 2mm4, and an arc-shaped groove adapted to the elastic protrusion is arranged on the inner cavity wall of the U-shaped limit cavity.

[0006] As a preferred implementation manner in this embodiment, the elastic protrusion is made of a mixture of magnetic powder and rubber materials.

[0007] As a preferred implementation manner in this embodiment, the magnetic force between the elastic protrusion and the second plate body is controlled between 1 and 3N.

[0008] As a preferred implementation manner in this embodiment, a plurality of reinforcing strips in a T-shaped structure are arranged in a row on the top wall of the rectangular accommodating cavity, and a T-shaped slot adapted to the reinforcing strips is arranged at the upper end of the insertion plate.

[0009] In summary, the technical effects and advantages of the utility model:

[0010] The structure of the utility model is reasonable. The fastener can adjust the size of the notch according to needs, so that the fastener can meet the installation requirements for keels of different widths.

[0011] In the utility model, an elastic protrusion and an arc-shaped groove adapted thereto are provided, which can prevent the first plate body and the second plate body from being easily separated after being inserted and installed.

[0012] In the utility model, the protruding end of the elastic protrusion exceeds the outer plane end of the limiting strip by 2 to 4 mm. If the exceeding distance is too large, it will take a lot of effort to complete the insertion of the insertion plate into the rectangular accommodation cavity, which is rather laborious. If the exceeding distance is too small, the extrusion force is likely to be too small, which is likely to cause the first plate body and the second plate body to be separated after the insertion is completed.

[0013] In the utility model, a reinforcing strip and a T-shaped slot are provided. Through the insertion fit of the T-shaped reinforcing strip and the T-shaped slot 10, the structural strength between the first plate body and the second plate body after the insertion is completed can be enhanced.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-3 A fastener for dry-hanging wall tiles as shown, which includes a mounting plate provided with two L-shaped mounting limit plates 1 thereon. A notch adapted to the keel is provided between the two mounting limit plates 1. The mounting plate includes a first plate body 2 and a second plate body 3. A plug plate 4 is installed at the right end of the first plate body 2. A rectangular accommodating cavity adapted to the plug plate 4 is provided at the left end of the second plate body 3. Limit strips 5 are fixed at both ends of the plug plate 4. A U-shaped limit cavity 7 adapted to the limit strips 5 is provided at the left end of the second plate body 3. The two mounting limit plates 1 are respectively installed on the first plate body 2 and the second plate body 3.

[0023] During installation, the plug block 4 is inserted into the rectangular accommodating cavity provided on the second plate body 3, and by moving the second plate body 3 relative to the first plate body 2, the distance between the two mounting limit plates 1 is adjusted, and then the size of the notch is adjusted, so that the fastener can adapt to the installation requirements of keels with different widths.

[0024] It should be noted that, first, since the first plate body 2 and the second plate body 3 of the fastener can be disassembled, when the first plate body 2 or the second plate body 3 is damaged, the damaged part can be directly replaced, avoiding the replacement of the entire fastener and reducing property losses; second, through the insertion and cooperation of the limit strips 5 and the U-shaped limit cavity 7, the first plate body 2 and the second plate body 3 can only move horizontally (its horizontal movement can adjust the size of the notch).

[0025] As a preferred implementation manner in this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, semi-circular elastic protrusions 6 are provided on the left sides of the two limit strips 5. The protruding ends of the elastic protrusions 6 extend 2 to 4 mm beyond the outer plane end of the limit strips 5. Arc-shaped grooves 8 adapted to the elastic protrusions 6 are provided on the inner cavity wall of the U-shaped limit cavity 7.

[0026] During the process of inserting the plug board 4 into the rectangular accommodating cavity, at the initial stage, it will be subjected to a relatively large extrusion force from the elastic protrusion 6. When the outer surface of the semi-circular elastic protrusion 6 moves into the arc-shaped groove 8 (at this time, the extrusion effect of the elastic protrusion 6 on the second plate body 3 is relatively small), the extrusion force is released. At this time, a relatively small force can be used to move the plug board 4 in the rectangular accommodating cavity, which is convenient for personnel to adjust the size of the notch. After installation, the elastic protrusion 6 will form an extrusion effect with the side wall of the arc-shaped groove 8, which can prevent the first plate body 2 and the second plate body 3 from separating easily after installation. If necessary, a relatively large force needs to be applied to separate the first plate body 2 and the second plate body 3.

[0027] It should be noted that, first, the protruding end of the elastic protrusion 6 exceeds the outer plane end of the limiting strip 5 by 2 to 4 mm. If the exceeding distance is too large, it will be very laborious to complete the insertion of the plug board 4 into the rectangular accommodating cavity. If the exceeding distance is too small, the extrusion force is likely to be too small, which is likely to cause the first plate body 2 and the second plate body 3 to separate after insertion. Second, both ends of the arc-shaped groove 8 are closed ends.

[0028] As a preferred implementation manner in this embodiment, the elastic protrusion 6 is made of a mixture of magnetic powder and rubber material.

[0029] The elastic protrusion 6 made of a mixture of magnetic powder and rubber material has improved wear resistance and service life compared with the elastic protrusion 6 made of rubber material, and it also has magnetism. Through its magnetism (which can generate magnetic adsorption with the second plate body 3 made of alloy material), the extrusion effect between the elastic protrusion 6 and the second plate body 2 is enhanced, so that a relatively small area of the elastic protrusion 6 can also provide a sufficient large force, and at the same time, it also provides a relatively large adjustment range for the subsequent movement of the second plate body 3 relative to the first plate body 2.

[0030] As a preferred implementation manner in this embodiment, the magnetic force between the elastic protrusion 6 and the second plate body 3 is controlled between 1 and 3 N.

[0031] If the magnetic effect is too small, the force between the elastic protrusion 6 and the second plate body 3 will be too small, resulting in easy separation after insertion. If the magnetic force is too large, the operator needs to apply a relatively large force to complete the insertion of the first plate body 2 and the second plate body 3 and the subsequent separation of the insertion. Controlling the magnetic force between 1 and 3 N can not only prevent separation easily, but also facilitate the insertion and installation of personnel and the subsequent separation of the insertion.

[0032] As a preferred implementation manner in this embodiment, as Figures 3-5 shown, a plurality of reinforcing strips 9 with a T-shaped structure are arranged on the top wall of the rectangular accommodating cavity, and a T-shaped slot 10 adapted to the reinforcing strips 9 is provided at the upper end of the plug board 4.

[0033] Through the insertion and cooperation of the reinforcing strip 9 with a T-shaped structure and the T-shaped slot 10, the structural strength between the first plate body 2 and the second plate body 3 after the insertion can be enhanced.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
