Abstract
The utility model discloses a flange face lock nut, including the hexagon, establish the screw hole in the hexagon, the lower part body coupling flange body of hexagon, its characterized in that: the lower end face of the flange body is provided with a tapered hole which is coaxial with the threaded hole in the center position, a locking ring made of plastic is arranged in the tapered hole, the bottom end face of the locking ring protrudes out of the lower end face of the flange body, the outer circle of the locking ring is provided with an outer conical surface which is matched with the inner conical surface of the tapered hole, the height of the locking ring is smaller than the depth of the tapered hole, the locking ring is provided with a cutting notch in the outer circle so that the locking ring has radial shrinkage capacity, and the diameter of the inner hole of the locking ring. The utility model discloses can realize fastening locking function in flange face department, make the nut appearance of installation more succinct pleasing to the eye, change the locking ring moreover and can repetitious usage, guarantee good locking function.
Description
Technical Field
The utility model relates to a fastener product, concretely relates to flange face lock nut.
Background
The flange nut is widely applied due to the large fastening area, if the flange nut needs to realize the locking function, a locking sheet or a locking ring needs to be arranged at the top of the nut like other nuts, and the locking sheet or the locking ring needs to be riveted and fixed by using a flange of a thin-wall sleeve structure at the top of the nut, so that the flange nut with the locking function has a more complex structure and a concise and attractive appearance compared with a common flange nut; in addition, after the flange nut with the locking structure is used for one time, the locking function is greatly weakened, and the whole nut is generally scrapped.
Disclosure of Invention
The utility model aims at providing a not enough to prior art, the utility model aims at providing a can locate to realize fastening locking function in the flange face, make the installation appearance more succinct pleasing to the eye, change the locking ring moreover and can repetitious usage, guarantee the flange face lock nut of good locking function.
The utility model discloses a through following technical scheme implementation:
flange face lock nut establishes the screw hole including the hexagon in the hexagon, the lower part body coupling flange body of hexagon, its characterized in that: the lower end face of the flange body is provided with a tapered hole which is coaxial with the threaded hole in the center position, a locking ring made of plastic is arranged in the tapered hole, the bottom end face of the locking ring protrudes out of the lower end face of the flange body, the outer circle of the locking ring is provided with an outer conical surface which is matched with the inner conical surface of the tapered hole, the height of the locking ring is smaller than the depth of the tapered hole, the locking ring is provided with a cutting notch in the outer circle so that the locking ring has radial shrinkage capacity, and the diameter of the inner hole of the locking ring.
Above-mentioned technical scheme's flange face lock nut can realize fastening locking function in flange face department, and the use is: when the nut is screwed, the locking ring is firstly contacted with the fastening end face and then is pressed tightly by the tapered hole, in the pressing process, under the pushing action of the tapered surface, the inner hole of the locking ring generates radial contraction, and finally when the nut is screwed tightly, the inner hole of the locking ring can be tightly held on the excircle of the bolt and the screw rod, so that the reliable locking effect is achieved; above-mentioned flange face lock nut after installation, because the locking position is sheltered from, is as good as with ordinary flange face nut, and the appearance is more succinct pleasing to the eye. In addition, the flange surface locking nut only shows a locking effect when the nut is screwed up quickly, so that the locking function is better ensured; in addition, the flange surface locking nut can realize a new nut locking function only by replacing the locking ring after being used every time, and the replacement of the locking ring is very convenient.
Preferably, the diameter of the inner bore of the locking ring is equal to the major diameter of the threaded bore.
Drawings
The utility model discloses there is following figure:
figure 1 is a half-sectional view of the present invention,
fig. 2 is a bottom view of fig. 1.
Detailed Description
As shown in the figure, the utility model discloses a flange face lock nut, including hexagon 1, establish screw hole 3 in the hexagon 1, the integrative flange body 2 of lower part of hexagon 1, flange body 2's lower terminal surface is equipped with bell mouth 4 coaxial with screw hole 3 at central point, the locking ring 5 of packing into the plastics material in bell mouth 4, the bottom terminal surface protrusion of locking ring 5 is in flange body 2's lower terminal surface, the excircle of locking ring 5 has the interior conical surface phase-match of the external conical surface and bell mouth 4, locking ring 5 highly is less than the degree of depth of bell mouth 4, locking ring 5 is equipped with at the excircle and cuts off breach 7 and makes locking ring 5 have radial contraction ability, the hole 6 diameter of locking ring 5 equals the big footpath of screw hole 3. The flange face locking nut only embodies the locking effect when the nut is screwed up soon, and the locking function is better guaranteed, and the locking ring locking nut in the prior art starts to play a role when the nut is screwed into the bolt and the screw, and finally the locking effect has certain discount.
Claims (2)
1. Flange face lock nut establishes the screw hole including the hexagon in the hexagon, the lower part body coupling flange body of hexagon, its characterized in that: the lower end face of the flange body is provided with a tapered hole which is coaxial with the threaded hole in the center position, a locking ring made of plastic is arranged in the tapered hole, the bottom end face of the locking ring protrudes out of the lower end face of the flange body, the outer circle of the locking ring is provided with an outer conical surface which is matched with the inner conical surface of the tapered hole, the height of the locking ring is smaller than the depth of the tapered hole, the locking ring is provided with a cutting notch in the outer circle so that the locking ring has radial shrinkage capacity, and the diameter of the inner hole of the locking ring.
2. The flange face lock nut of claim 1, wherein: the diameter of the inner hole of the locking ring is equal to the major diameter of the threaded hole.
