Description
Technical Field
The utility model relates to the technical field of fasteners, in particular to an integrated anti-loosening nut component.
Background
Nuts are common fastener fittings, often used with bolts. Under high frequency, large amplitude vibration or impact conditions, the nut typically moves relative to the bolt, resulting in loose displacement of the fastened object, i.e., failure of the fastening. For this reason, the search for anti-loosening fasteners has been ongoing.
The better mode of locking effect at present just sets up the interlocking structure of nut, nut. For example, in the integrally movably connected nut and washer assembly structure disclosed in the chinese application CN202011057385, wedge-shaped blocks engaged with each other are arranged on the contact surfaces of the nut and the washer, so that the wedge-shaped blocks are staggered to press the washer when the nut is loosened, and the nut and the washer are still kept in a fastened state. For the screw cap, a matched screw cap and a matched gasket are required to be adopted when the screw cap is used, otherwise, the wedge block is not matched, the using effect is influenced, and in the actual using process, due to the error of workers, the conditions of wrong installation direction of the gasket, wrong specification use of the gasket and the like exist.

The specific scheme of the utility model is as follows:
an integrated anti-loosening nut component comprises a nut and a gasket which are coaxially arranged, wherein the nut and the gasket are movably connected through an interlocking retaining structure, the interlocking retaining structure comprises a retaining block A positioned at the bottom of the nut and a retaining block B positioned at the top of the gasket, the retaining block A and the retaining block B can be completely wedged, and the vertical distance between the top of the nut and the bottom of the gasket is shortest when the retaining block A and the retaining block B are completely wedged; when the nut and the gasket rotate relatively, the stopping block A and the stopping block B slide relatively to increase the vertical distance between the top of the nut and the bottom of the gasket gradually, and the bottom of the gasket is provided with anti-slip teeth; be provided with limit structure on the terminal surface of nut and gasket contact, limit structure inserts the middle part through-hole of gasket and with gasket clearance fit for restriction gasket and nut separation, make gasket and nut even as an organic whole and the gasket can be for the nut rotation.
As an embodiment of the present invention, the height of the limiting structure is lower than the thickness of the gasket, so that the other end of the limiting structure does not extend out of the middle through hole of the gasket after the gasket is completely wedged with the nut, thereby completely avoiding the possibility of the limiting structure contacting with the object to be fixed, and improving the application range of the nut.
As an embodiment of the present invention, the through hole in the middle of the gasket is in a bell mouth shape; the limiting structure is a limiting ring, the outer wall of the peripheral side face of the limiting ring is in a horn mouth shape, one end with the smaller outer diameter of the limiting ring is connected with the nut, and the outer diameter of one end with the larger outer diameter is between the maximum value and the minimum value of the inner diameter of the through hole in the middle of the gasket.
As an embodiment of the present invention, when the nut assembly is disassembled, the nut and the gasket need to be rotated together, and usually the wrench locks the non-return block B and the nut, and for the anti-theft requirement, the overall height of the non-return block B is made very low, so that the wrench cannot lock the non-return block B, the gasket is made into a circular shape, and the peripheral side surface of the gasket is provided with the groove, so that the bolt can be smoothly disassembled only when the nut and the gasket are locked by a specific tool.
In one embodiment of the present invention, the grooves are distributed uniformly around the circumference.
Compared with the prior art, the method has the following advantages:
the nut and the gasket are integrally connected, the nut and the gasket cannot fall off, the carrying is convenient, and the direction and gasket specification use errors in the installation process are avoided.

Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited to these examples.
In the description of the present invention, it is to be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and should not be construed as limiting the present invention.
Example 1:
referring to fig. 1 to 4, an integrated anti-loosening nut assembly includes a nut 1 and a washer 2 coaxially disposed, the nut 1 is a hexagonal nut, the nut 1 and the washer 2 are movably connected by an interlocking retaining structure, the interlocking retaining structure includes a retaining block a 101 located at the bottom of the nut 1 and a retaining block B201 located at the top of the washer 2, the retaining block a 101 and the retaining block B201 can be completely wedged, and when the two are completely wedged, the vertical distance between the top of the nut 1 and the bottom of the washer 2 is shortest; when the nut 1 and the washer 2 rotate relatively, the stopping block a 101 and the stopping block B201 slide relatively to each other, so that the vertical distance between the top of the nut 1 and the bottom of the washer 2 is gradually increased, and the bottom of the washer 2 is provided with the anti-slip teeth 202.
