Abstract
The utility model discloses a self-locking flare-in nut, which comprises a nut body with a threaded hole. The nut body is cylindrical, one end of the nut body is provided with a cylindrical flare-in, the outer circle diameter of the flare-in is smaller than that of the nut body, the inner circle diameter of the flare-in is larger than that of the threaded hole of the nut body, an end face of the end of the nut body with the flare-in is provided with end face teeth, and separating slots are arranged on the cylinder of the nut body. During mounting, as a screw can be screwed onto the nut without being clamped by other tools, the nut has the advantages of small space occupation. Besides, the self-locking flare-in nut has the advantages of convenient use, loosening resistance during usage, safe and reliable connection, simple structure, fine processing and the like.
Description
Technical field
The utility model relates to a kind of riveting self-locking nut that turns over, and belongs to the technical field that is threaded.
Background technique
At present, nut of the prior art generally adopts square nut or six-sided nut, and these nuts must the employing instrument block nut in use, prevent its rotation, screw could be screwed in the nut.But, in some use occasion, can't nut be blocked tool using, thereby also screw can't be screwed in the nut.Therefore, existing square nut or six-sided nut exist problems such as the space of occupying is big, installation is not too convenient and occur easily becoming flexible in use in the process of using.
The model utility content
The purpose of this utility model is: provide a kind of do not need with instrument block nut just can be screwed into screw in the nut and nut take up space less, easy to use, be difficult for when using taking place loosening, connect and turn over the riveting self-locking nut reliably, thereby overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of riveting self-locking nut that turns over of the present utility model comprises the nut body that is provided with tapped hole, the profile of nut body is a cylinder type, turn over riveting skirt body what an end of nut body was provided with cylinder type, turn over the outside diameter D of the outside diameter D1 of riveting skirt body, turn over the tapped hole diameter d of the interior circular diameter D2 of riveting skirt body greater than nut body less than nut body; Be provided with on the end face that turns over riveting skirt body one end at nut body and also be provided with the end face tooth, on the cylinder of nut body, be provided with the separation groove.
The groove depth H of above-mentioned separation groove is (D+d)/2≤H＜D.
The groove width B of above-mentioned separation groove is 1～5 millimeter.
Owing to adopted technique scheme, the utility model is designed to cylindrical body to the change of the hexagon of plain nut, and realized nut is fixed on purpose on the connected panel reliably with the end face tooth after turning over riveting by turning over riveting skirt body, when turning screw, can prevent that also nut from rotating.And because the utility model partly processes the separation groove with the conventional machinery method for processing at nut body, make the nut body part be divided into two-part naturally, along with screw is screwed into when the tight condition, upper half part nut body still can be one until screw is firmly locked to axial generation one little displacement, and lower nut produces loosening problem thereby solved in working order effectively.Therefore, the utility model compared with prior art, because the utility model does not need to block nut with instrument when mounted and just screw can be screwed in the nut, so have the nut less advantage that takes up space, in addition the utility model also have easy to use, be difficult for taking place advantages such as loosening, that attachment security is reliable, simple in structure, processability is good when using.

Fig. 2 is the left TV structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: make of the present utility model a kind of when turning over the riveting self-locking nut, its nut body 3 that is provided with tapped hole can adopt traditional nut Manufacturing material to make, the screw thread of its tapped hole can be determined by traditional approach and makes according to the needs that use, during making, the shape fabricating of nut body 3 is become cylinder type, and turn over riveting skirt body 1 what an end of nut body 3 was produced cylinder type, the outside diameter D1 that turns over riveting skirt body 1 is made into outside diameter D less than nut body 3, and the interior circular diameter D2 that will turn over riveting skirt body 1 is made into the tapped hole diameter d greater than nut body 3; Be provided with on the end face that turns over riveting skirt body 1 one ends at nut body 3 and produce end face tooth 4 simultaneously, and the mode by machining processes and separates groove 2 on the cylinder of nut body 3; When make separating groove, the groove depth H that separates groove 2 is controlled at the scope of (D+d)/2≤H＜D, and the groove width B that will separate groove 2 is controlled at 1～5 millimeter scope.
Claims (3)
