According to the patent document with the publication number of CN202790011U, the anti-loose flange nut is disclosed, and belongs to the technical field of machinery. The problems that thread loads of all parts of an existing flange nut are uneven in distribution and poor in anti-loosening effect are solved. The anti-loose flange nut comprises a nut body, wherein the nut body comprises an annular flange part and a connecting part which is connected with the flange part into a whole, and one end of the connecting part, which is close to the flange part, is provided with an annular groove. The anti-loosening flange nut has the advantages of high fatigue strength of threaded connection, uniform distribution of threaded loads of all parts, good anti-loosening effect of the nut, simple structure, convenience in manufacturing and long service life; but it has the following disadvantages:

it only increases frictional force through anti-skidding tooth to play locking effect, but when flange nut received external continuous vibration influence, still can take place not hard up phenomenon, thereby lead to flange nut not hard up to drop.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a multiple locking flange nut, the effectual solution only increases frictional force through the antiskid tooth to play locking effect, but when flange nut received external continuous vibration influence, still can take place not hard up phenomenon, thereby lead to the not hard up problem that drops of flange nut.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a multiple locking flange nut, includes the nut body, and the center of nut body forms the screw, the top of nut body evenly is formed with locking arch, and the mounting groove has still evenly been seted up on the top of nut body, and the length direction perpendicular to nut body's of mounting groove radial direction is provided with anti-loosening member in the mounting groove.

Preferably, the locking member includes an inclined portion fixedly connected to the mounting groove and a vertical portion integrally connected to the inclined portion.

Preferably, the inclined portion has an arc-shaped geometry and protrudes outward.

Preferably, a through hole communicated with the screw hole is formed in the mounting groove, an extrusion block is arranged inside the through hole, and the extrusion block drives the anti-loosening piece to move out of the mounting groove when being pressed.

Preferably, one end of the extrusion block close to the screw hole forms an extrusion surface, one end of the extrusion block far away from the screw hole forms an extrusion groove, and the bottom end of the vertical part forms an inclined surface matched with the extrusion groove.

Compared with the prior art, the beneficial effects of the utility model are that:

in operation, through the cooperation use of the locking arch that sets up and anti-loosening piece, can increase the friction dynamics between nut body and the object through locking arch when using, play locking effect, the use of anti-loosening piece is prevented in the cooperation simultaneously, can avoid the nut body to take place not hard up phenomenon of backing up when receiving the exogenic action, stability when further improving the nut body and using.

in the figure: 1. a nut body; 2. a screw hole; 3. anti-loosening bulges are arranged; 4. mounting grooves; 5. an anti-loosening element; 501. an inclined portion; 502. a vertical portion; 503. a bevel; 6. a through hole; 7. extruding the block; 701. extruding surface; 702. the groove is pressed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is given by figures 1-3, the utility model relates to a multiple anti-loosening flange nut, which comprises a nut body 1, wherein a screw hole 2 is formed in the center of the nut body 1, anti-loosening protrusions 3 are uniformly formed on the top end of the nut body 1, mounting grooves 4 are also uniformly formed on the top end of the nut body 1, the length direction of the mounting grooves 4 is vertical to the radial direction of the nut body 1, and anti-loosening elements 5 are arranged in the mounting grooves 4; the anti-loosening element 5 comprises an inclined part 501 fixedly connected with the mounting groove 4 and a vertical part 502 connected with the inclined part 501 into a whole; the inclined portion 501 is arc-shaped in geometry and protrudes outward;

under the user state, when nut body 1 and screw cooperation are fixed the object, through the locking arch 3 that sets up, can form the extrusion to the surface of object, play locking effect, simultaneously when rotating nut body 1, because rake 501 is the arc, consequently can not block its rotation, and when rotating nut body 1 in the opposite direction, because the obstruction of perpendicular portion 502 to avoid nut body 1 to take place the antiport, further play locking effect.

Furthermore, a through hole 6 communicated with the screw hole 2 is formed in the mounting groove 4, an extrusion block 7 is arranged inside the through hole 6, and the extrusion block 7 drives the anti-loosening element 5 to move out of the mounting groove 4 when being pressed; one end of the extrusion block 7 close to the screw hole 2 forms an extrusion surface 701, one end of the extrusion block 7 far away from the screw hole 2 forms an extrusion groove 702, and the bottom end of the vertical part 502 forms an inclined surface 503 matched with the extrusion groove 702;

under the user state, after the screw enters into screw 2 in the nut body 1, the pin head of screw produces the extrusion to the extrusion face 701 on the extrusion piece 7, thereby make extrusion piece 7 along the motion of through-hole 6, extrusion groove 702 on the extrusion piece 7 produces the extrusion to inclined plane 503 on the perpendicular part 502, thereby make anti-loosening member 5 stretch out mounting groove 4, so that play locking effect when using, and when not using, anti-loosening member 5 is located the inside of mounting groove 4, thereby can not make the more arch of surface formation of nut body 1, be convenient for the staff takes it, can not produce the damage to the staff.
