[0037] like Figures 1 to 8 As shown; the utility model provides a fastening nut, which includes a locking member 1, a cushion member 2 and an extension member 3; the locking member 1 is provided with a threaded hole 11 and at least two first through holes 12, the first through holes 12 are arranged at intervals along the locking member 1, and the threaded hole 11 is arranged between any two adjacent first through holes 12; the cushion member 2 and the locking member 1 are arranged at intervals up and down, and the cushion member 2 is provided with a second through hole 21 corresponding to the threaded hole 11; the extension member 3 is arranged in a one-to-one correspondence with the first through holes 12, one end of the extension member 3 is connected to the cushion member 2, and the other end of the extension member 3 extends in a direction away from the cushion member 2; the locking member 1 is movably arranged on the extension member 3 through the first through hole 12, and a limiting protrusion 31 is provided at the end of the extension member 3 away from the cushion member 2 to limit the locking member 1 from detaching from the extension member 3; the extension member 3 is elastic.

[0038] Through the above structure, such as Figures 6 to 8When installing and fastening on the mounting hole of the ceramic as shown, it is only necessary to apply force to the extension piece 3 to make it elastically deform, and the horizontal locking piece 1 becomes inclined, so that the locking piece 1 can be inserted into the mounting hole from the top of the mounting hole. After insertion, the locking piece 1 can be restored to the horizontal position by the restoring force of the extension piece 3, so that the pad body 2 and the locking piece 1 can be located on both sides of the mounting hole, and then the screw or bolt can be extended into the threaded hole 11 through the second through hole 21, and screwing the screw or bolt can make the locking piece 1 move along the extension piece 3 toward the mounting hole to complete the fastening operation; the whole process does not require hands or tools to extend under the ceramic, so that the installation is easier, and there is no need to set up an installation space for installation, which can provide a larger installation space for other components.

[0039] like Figure 4 As shown, in some embodiments, the number of the first through holes 12 can be two or more than two. In the current embodiment, for a single mounting hole and in order to save resources, the number of the first through holes 12 can be set to two, and the threaded hole 11 is located between the two first through holes 12. In addition, in order to facilitate installation and facilitate the locking member 1 to move up along the extension member 3 as quickly as possible when screwing, when the locking member 1 is parallel to the cushion member 2, the first through hole 12 on the locking member 1 is coaxial with the second through hole 21 on the cushion member 2.

[0040] like Figure 4 As shown, in some embodiments, the first through hole 12 includes a first hole 121 and a second hole 122, wherein the first hole 121 and the second hole 122 are cross-connected; in the current embodiment, the first hole 121 and the second hole 122 are both rectangular, and the two are cross-connected to form a cross-shaped first through hole 12, the size of the first hole 121 is larger than the size of the second hole 122, and the extension piece 3 is sheet-shaped, so that the extension piece 3 can be inserted from the first hole 121 through the deformation characteristics of the extension piece 3, and then transferred to the second hole 122, so that the locking piece 1 can be slidably connected to the extension piece 3 through the second hole 122, that is, the first hole 121 and the second hole 122 of different sizes are used to facilitate the installation of the locking piece 1 to the first through hole 12, which is convenient for production and installation; the above structure also facilitates the replacement of the locking piece 1.

[0041] like Figure 3 As shown, in some embodiments, the size of the limiting protrusion 31 gradually decreases from one end close to the extension member 3 to the other end, that is, the limiting protrusion 31 is pointed, which facilitates the extension member 3 to be inserted through the first hole 121. It can be understood here that the pointed limiting protrusion 31 can also facilitate the extension member 3 to pass through the mounting hole on the ceramic.

[0042] like Figure 3As shown, in some embodiments, the extension member 3 also includes a large diameter section and a small diameter section connected in sequence, wherein the large diameter section is connected to the cushion member 2, and the limiting protrusion 31 is located at the end of the small diameter section away from the large diameter section, and at least the above-mentioned large diameter section is elastic, that is, at least the large diameter section can undergo a certain elastic deformation, so that the locking member 1 can be inserted through the mounting hole. Exemplarily, the large diameter section can be made of rubber. In some other embodiments, plastic materials can also be used. It should be noted here that in other embodiments, the above-mentioned small diameter section and the limiting protrusion 31 can be made of elastic materials as long as they do not affect the screwing.

[0043] like Figure 4 As shown, in some embodiments, a protruding wing 13 is provided on the side of the locking member 1 facing the pad member 2, the two protruding wings 13 are arranged opposite to each other, and the threaded hole 11 is located between the two protruding wings 13. When the locking member 1 is tightened, the protruding wing 13 can abut against the ceramic to prevent the locking member 1 from being squeezed and deformed around the threaded hole 11, thereby losing the locking function. Exemplarily, the protruding wing 13 is formed by bending the opposite edges of the locking member 1 in one piece, which is convenient for manufacturing.

[0044] like Figures 1 to 3 As shown, in some embodiments, the pad member 2 includes a shell 22, and the shell 22 can be made of a hard material such as plastic or metal. A groove is provided on the side of the shell 22 facing the locking member 1, and a gasket 23 is embedded in the groove. The gasket 23 can be made of rubber. The second through hole 21 passes through the groove and the above-mentioned gasket 23, so that when screwing, the gasket 23 can be prevented from being squeezed into the mounting hole by the screw or bolt being screwed through the protection of the shell 22, thereby avoiding the failure of the anti-slip effect. It should be noted here that the large diameter section of the extension member 3 is connected to the shell 22 or the gasket 23. In one embodiment, an embedding protrusion 24 is provided on the gasket 23, and the embedding protrusion 24 extends into the mounting hole during installation. The embedding protrusion 24 can be integrally formed with the gasket 23, and the second through hole 21 passes through the above-mentioned embedding protrusion 24. The extension member 3 is connected to the opposite sides of the embedding protrusion 24, thereby ensuring the stability of the installation. In another embodiment, the embedding protrusion 24 can be arranged at the bottom of the groove, that is, the embedding protrusion 24 can be arranged on the shell 22 and be integrally formed with the shell 22, so that the gasket 23 is an annular gasket, and the gasket 23 is sleeved on the embedding protrusion 24 and embedded in the above-mentioned groove.

[0045] The utility model also provides a fastening assembly, which includes a screw or a bolt, and also includes the above-mentioned fastening nut. The screw or bolt can pass through the second through hole 21 and be screwed into the threaded hole 11, so that the above-mentioned fastening assembly can be fixed without manual labor or tools during installation, making the installation easier and eliminating the need to set up an installation space for installation.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
