The specific implementation mode is as follows:
in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:
referring to fig. 1-7, a novel fast-assembling nut comprises a male nut 1, a female nut 2 and a screw rod 3;
the male nut 1 is provided with a frustum-shaped plug 11, the frustum-shaped plug 11 is provided with an eccentric circular through hole 12 for the screw rod 3 to pass through, and the inner side surface of the eccentric circular through hole 12 is provided with a fan-shaped arc internal thread 13; the eccentric circular through hole 12 is formed by overlapping and combining a circular through hole 121 in clearance fit with the screw rod 3 and an internal thread through hole 122 meshed with the screw rod 3. The inner side surface of the circular through hole 121 is a smooth arc surface. The circular through hole 121 of the eccentric circular through hole 12 is in clearance fit with the screw rod 3, so that the male nut 1 can freely slide on the screw rod 3.
The female nut 2 is provided with a frustum-shaped through hole 21 which is in axial sliding fit with the frustum-shaped plug 11; the screw rod 3 penetrates through the male nut 1 and the female nut 2; when the male nut 1 is sleeved with the female nut 2, the external thread of the screw rod 3 is meshed with the sector arc internal thread 13 of the male nut 1. Therefore, when the male nut 1 and the female nut 2 are combined into a whole, the quick-assembly nut limits the sliding track of the male nut 1 by using the female nut 2, so that the male nut 1 must work in the thread track, and the effect of quick thread locking is achieved.
And a circular through hole 22 in clearance fit with the screw rod 3 is arranged above the frustum-shaped through hole 21 of the female nut 2, and the circular through hole 22 is communicated with the frustum-shaped through hole 21. The circular through hole 22 and the frustum-shaped through hole 21 of the female nut 2 and the circular through hole 121 of the male nut 1 are coaxial. The circular through hole 22 and the frustum-shaped through hole 21 of the female nut 2 are designed as concentric circles, and can play a role in guiding. The conical surface of the frustum-shaped through hole 21 of the female nut 2 is in transition fit with the conical surface of the frustum-shaped plug 11 of the male nut 1. When the male nut 1 and the female nut 2 are combined into a whole, since the tapered surface of the frustum-shaped through hole 21 of the female nut 2 contacts with the tapered surface of the frustum-shaped plug 11 of the male nut 1, the screw 3 is displaced from the circular through hole 121 of the male nut 1 to the sector-shaped internal thread 13, so that the external thread of the screw 3 is engaged with the sector-shaped internal thread 13 of the male nut 1.
The connection part of the circular through hole 22 and the frustum-shaped through hole 21 is provided with a first step part 23 used for clamping the top of the frustum-shaped plug 11 of the male nut 1. When the male nut 1 and the female nut 2 are combined into a whole, the top of the frustum-shaped plug 11 of the male nut 1 abuts against the first step portion 23, and the first step portion 23 prevents the male nut 1 from continuously moving towards the reducing direction of the frustum-shaped through hole 21. The bottom of the frustum-shaped plug 11 of the male nut 1 is provided with a second stepped part 14 for clamping the end part of the female nut 2, and the second stepped part 14 can prevent the female nut 2 from continuously moving towards the diameter expanding direction of the frustum-shaped plug 11.
The male nut 1 is provided with two concave positions 15 which are convenient for rotating the male nut 1 on the circumferential side surface opposite to the other end of the frustum-shaped plug 11, and the two concave positions 15 are symmetrically distributed. When the male nut 1 and the female nut 2 are combined into a whole, the two concave parts 15 are clamped by using auxiliary tools such as a spanner or pliers and the like to rotate, so that the locking degree of the male nut 1, the female nut 2 and the screw rod 3 can be further strengthened.
The using method comprises the following steps: firstly, respectively sleeving a male nut 1 and a female nut 2 on a screw rod 3, enabling one end of the screw rod 3 to penetrate through a mounting hole at a position to be fixed, then pushing the male nut 1 towards the female nut 2 until the male nut 1 and the female nut 2 are combined into a whole, and enabling a fan-shaped arc internal thread 13 of the male nut 1 to be meshed with the screw rod 3; then, the male nut 1 is rotated while being held between the two recesses 15 by an auxiliary tool such as a wrench or pliers, thereby further reinforcing the degree of engagement between the male nut 1 and the screw 3.
The utility model discloses a fast-assembling nut, because female nut 2 does not have the screw thread restriction, can slide freely; when the male nut 1 is separated from the female nut 2, the screw rod 3 slides freely in the eccentric circular through hole 12, and the design can greatly reduce the sliding time of the nut. When the female nut 2 and the male nut 1 are integrated, the female nut 2 limits the sliding track of the male nut 1, and the male nut 1 must work in the thread track in the sector arc internal thread 13 and cannot freely slide on the screw rod 3, so that the thread locking effect is achieved.
Finally, it should be noted that: the above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
