[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0023] like Figure 1 The nut 10 for fixing a smart central control panel of the present application is shown, comprising: a threaded portion 11, a clamping groove 12 and a covering disc 13, wherein the covering disc 13 is arranged above the clamping groove 12, and the threaded portion 11 is arranged below the clamping groove 12. The threaded portion 11 is used to be screwed into the pre-installation hole 101 of the smart central control panel, thereby fixing the smart central control panel to the pre-installation position, the clamping groove 12 is used for the plastic part 100 at the end of the pre-installation hole 101 of the smart central control panel to be clamped to prevent the nut 10 from loosening, and the covering disc 13 is used to cover the plastic part 100 on the upper side of the end of the pre-installation hole 101.

[0024] That is to say, when the threaded portion 11 of the nut 10 is screwed into the pre-installed hole 101 to a preset position, the plastic part 100 on the upper side of the end of the pre-installed hole 101 is snapped into the snapping groove 12. In this way, the screwed-in position of the nut 10 can be locked through the snapping cooperation between the snapping groove 12 and the plastic part 100, thereby preventing the nut 10 from loosening and falling off.

[0025] Furthermore, a plurality of anti-rotation protrusions 131 are formed on the circumferential side of the covering disc 13, and the anti-rotation protrusions 131 can increase the contact area between the covering disc 13 and the plastic part 100, thereby preventing the nut 10 from rotating relative to the plastic part 100, thereby improving the locking ability of the overall installation structure of the nut 10.

[0026] Furthermore, the lower end of the anti-rotation protrusion 131 is formed with an insertion slope 132. The insertion slope 132 can guide the lower end of the covering disc 13 to be inserted into the pre-installed hole 101 during the screwing process of the threaded portion 11, so that the locking performance of the screwing structure of the nut 10 can be improved by the compression structure between the insertion slope 132 and the hole wall of the pre-installed hole 101, thereby further improving the installation stability of the nut 10 relative to the pre-installed hole 101.

[0027] In addition, the inner circumferential surface of the bottom of the clamping groove 12 is formed with a plurality of anti-rotation ridges 121 in its circumferential direction. When the plastic part 100 is clamped into the clamping groove 12, the anti-rotation ridges 121 can increase the friction between the clamping groove 12 and the hole wall of the pre-installed hole 101, thereby further locking the nut 10 to prevent the nut 10 from rotating.

[0028] As a specific implementation, the outer diameter of the covering disk 13 is greater than the outer diameter of the threaded portion 11 , so that the thread gap can be covered and the stability of the installation structure of the nut 10 is improved.

[0029] Through the above technical solution, a larger covering disc 13 is designed on the top of the nut 10, and the diameter of the covering disc 13 is larger than the diameter of the threaded portion 11 of the nut 10, so that it can cover the surface of the plastic part 100 more widely. The circumferential surface of the covering disc 13 adopts an anti-slip texture design of a rotation-blocking protrusion 131 to increase the friction between the plastic part 100 and further improve the stability of the connection of the nut 10. In the transition area between the covering disc 13 and the threaded portion 11, a clamping groove 12 is designed. The edge of the upper end of the pre-installed hole 101 of the plastic part 100 can be accommodated by the clamping groove 12. When the nut 10 is tightened, the edge of the upper end of the pre-installed hole 101 of the plastic part 100 will be embedded in the clamping groove 12 to form a mechanical locking structure. This design not only increases the contact area, realizes multiple locking mechanisms, and makes the nut 10 and the plastic part 100 tightly connected, but also improves the anti-torsion ability of the connection, which can effectively prevent the nut 10 from loosening and falling off during vibration.

[0030] Therefore, the threaded mounting structure of the nut 10 used to fix the smart central control panel is stable and has a good locking function, which can effectively prevent the nut 10 from loosening and falling off, thereby ensuring the installation stability of the smart central control panel.

[0031] As a specific embodiment, a cylindrical hollow 111 is formed in the center of the threaded portion 11. The cylindrical hollow 111 is used for the threaded portion 11 to shrink when it is screwed into the pre-installed hole 101, thereby allowing the nut 10 to shrink and screw in, so that the edge of the plastic part 100 is stuck in the clamping groove 12. The threaded portion 11 here is an elastic structure with the performance of elastically shrinking in coordination with the hole wall of the pre-installed hole 101. While ensuring the stability of the structural installation, it also improves the smoothness of the installation of the nut 10. While using its elastic performance to lock, the edge of the plastic part 100 is safely stuck in the clamping groove 12 without cracking due to hard screwing.

[0032] Specifically, the diameter of the cylindrical hollow 111 is smaller than the radial thickness of the threaded portion 11 to ensure the stability of the threaded installation and locking structure of the threaded portion 11 .

[0033] A buffer portion 133 is formed on the upper edge of the covering disk 13, and the buffer portion 133 is used to relieve and release the stress between the covering disk 13 and the hole wall of the pre-installation hole 101 to avoid causing hard damage to the plastic part 100 at the pre-installation position and cracking thereof when the threaded locking installation nut 10 is installed.

[0034] Figure 2 , which is a second embodiment of the present technical solution, and which differs from the first embodiment in that the outer diameter of the covering disk 13a is equal to the outer diameter of the threaded portion 11a.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
