Technical Field

The invention relates to the field of fasteners, in particular to a three-dimensional multi-dimensional anti-loosening structure which is never loosened.

Background

The nut and the bolt or the screw are screwed together to form the anti-loosening assembly, the anti-loosening assembly is a part with a fastening effect, and an element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metal (such as copper) and other types according to different materials.

The existing anti-loosening fastener is mostly prevented from loosening by adopting two types, one type is famous for preventing loosening by inserting a wedge into a Japanese Hard LocK nut, but the design of a wedge boss of the Japanese Hard LocK nut has the following problems: when the nut needs to be locked, the nut can be locked by using larger torsion, so that the nut on the concave table is often forced to be opened by the nut on the convex table until the clamping effect is lost and the thread is slipped, and a great accident can be caused when the nut is used on an airplane or a high-speed rail or an aerospace; another is by incorporating a locdi washer on the bolt, but this prevention makes the fastening process of the bolt slower and also adds to the cost.

The existing patent numbers are: 202021856388.2, the patent name is a three-dimensional multidimension never-loosening anti-loosening structure, it prevents that the bolt from becoming flexible, and the piece of pressing from both sides through lower nut closely contradicts with the screw rod, and the border position that the piece of pressing from both sides kept away from lower nut tip realizes and screw rod in close contact with promptly, reaches the nut with the screw rod lateral wall and closely interlocks, and the other positions of the piece of pressing from both sides are compared and are kept away from lower nut one end tip position in the piece of pressing from both sides, and interlock intensity is little to influence whole locking effect.

Therefore, there is a need for an improved structure that overcomes the above-mentioned deficiencies.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the invention is further described with reference to the figures and the specific embodiments.

As shown in fig. 1 to 5, the three-dimensional multidimensional never-loosening anti-loosening structure provided by the invention comprises a screw rod 1, wherein an upper nut 2 and a lower nut 3 are screwed on the screw rod 1, an installation groove 4 is formed in one end, facing the lower nut 3, of the upper nut 2, and the installation groove 4 is communicated with an inner diameter hole of the upper nut 2; the lower nut 3 is provided with a plurality of clamping pieces 5 which are in a circumferential array and can be inserted into the mounting groove 4, the number of the clamping pieces 5 is four in the embodiment, a movable groove 6 is formed between every two adjacent clamping pieces 5, and the inner sides of the clamping pieces 5 are in threaded connection with the screw rod 1.

During the use, go up nut 2 and 3 butts of lower nut, and press from both sides tight piece 5 and insert in mounting groove 4, screw rod 1 penetrates nut 2, lower nut 3 and realizes threaded connection.

It realizes pressing from both sides the interlock structure of tight interlock of piece 5 and screw rod 1 to press from both sides to be provided with between piece 5 and the mounting groove 4, interlock structure is including seting up in press from both sides the deformation groove 7 of piece 5 towards 1 one side lateral wall of screw rod, set up in press from both sides tight piece 5 deviate from 1 one side lateral wall of screw rod and with deformation groove 7 lie in the bellying 8 of same position, set up in 4 lateral walls of mounting groove and can the butt portion 9 of bellying 8, bellying 8 all are the arc setting with butt portion 9 cross-section, butt portion 9 with 8 butt of bellying makes and press from both sides tight piece 5 deformation, and the position that presss from both sides tight piece 5 lies in deformation groove 7 both sides closely interlocks with 1 lateral wall of screw rod. When screw rod 1 twists in nut 2 and down between the nut 3 and screw up when targetting in place, go up nut 2 and nut 3 inseparable conflict down, and this moment, press from both sides tight piece 5 and go deep into in mounting groove 4, and bellying 8 contradicts with butt portion 9, and bellying 8, butt portion 9, deformation groove 7 is located the coplanar position, bellying 8 is after propping with butt portion 9, make and press from both sides tight piece 5 and produce deformation, press from both sides tight piece 5 and deform towards screw rod 1 direction at deformation groove 7 position promptly, and the border of deformation groove 7 both sides and screw rod 1 thread face in close contact with, realize the interlock effect, and effort is reverse setting when deformation groove 7 both sides border and screw rod 1 thread face interlock, press from both sides tight piece 5 all the other positions also produce corresponding deformation simultaneously and then with screw rod 1's screw thread is obviously cohesive, reach and prevent that screw rod 1 from becoming flexible function.

In this embodiment, the clearance of the movable groove 6 is gradually reduced in the direction away from the lower nut 3, and the side walls of two adjacent clamping pieces 5 far away from one end of the lower nut 3 are mutually closed. Pressing from both sides tight piece 5 and keeping away from 3 one end lateral wall positions of lower nut and being provided with touch multitouch 10, touch multitouch 10 is close to in the screw thread position of screw rod 1, and touch multitouch 10 is three horn shapes and sets up, and 3 one end borders of nut are kept away from down to two adjacent tight pieces 5 after each other supporting, and two adjacent touch multitouch 10 are contradicted and are deformed towards 1 direction of screw rod, and touch multitouch 10 is contradicted in 1 lateral wall of screw rod. The side wall of the mounting groove 4 is abutted against the edge position of one end, far away from the lower screw cap 3, of the clamping piece 5, so that the side walls of the two adjacent clamping pieces 5 are abutted. During the use, closely support the back when last nut 2 and lower nut 3, press from both sides tight piece 5 and deform 7 positions in the groove of deformation and towards 1 orientation deformation of screw rod, and press from both sides tight piece 5 this moment and keep away from 3 one ends of lower nut and also be and draw close each other, 4 lateral walls in mounting groove are the slope in addition and support the back with pressing from both sides tight piece 5 tip, make two adjacent 5 lateral wall positions of pressing from both sides tight piece contradict each other, thereby make two contact block 10 produce the deformation back, it is outstanding towards 1 orientation of screw rod, make contact block 10 pierce screw rod 1, and then play effective clamping screw 1, prevent that screw rod 1 is not hard up.

A clamping groove 11 is formed between the clamping piece 5 and the lower nut 3, the clamping groove 11 is located at the position where the clamping piece 5 deviates from the side wall of the screw rod 1, and the clamping groove 11 is parallel to the deformation groove 7. The clamping plate 5 is elastically deformed relative to the lower nut 3 by the clamping groove 11.

Go up nut 2 and be provided with first locking sawtooth structure 12 towards the terminal surface of nut 3 down, nut 3 is provided with the locking sawtooth structure 13 of second with first locking sawtooth structure 12 complex towards the terminal surface of nut 2 down, first locking sawtooth structure 12, the locking sawtooth structure 13 of second all are the setting of radiantly form. Through intermeshing between first locking sawtooth structure 12 and the locking sawtooth structure 13 of second, effectively avoid going up nut 2 and rotating each other between nut 3 down, play nut 2 and the effective fixed action of nut 3 down, make nut 2 and nut 3 be a holistic effect down.
