As shown in fig. 3, the circumferential arc length of the sleeve 10 occupied by the receding groove 11 is greater than the circumferential arc length occupied by the side wall of the sleeve 10, so as to ensure that there is enough internal thread surface to fit with the screw rod 1.
The number of the positioning blocks 12 is one, and the abdicating notch 11 is divided into two by the positioning blocks 12. The number of the positioning blocks 12 may also be two or three, but not limited thereto.
In this embodiment, as shown in fig. 2, the inner side of the positioning block 12 and the inner side of the abdicating slot 11 are located on the same circumferential surface.
One end of the threaded seat 20 is hinged with the sleeve seat 10, and the threaded seat 20 is provided with at least one second positioning part which can be matched with the first positioning part; the sleeve seat 10 is sleeved outside the screw rod 1, and the top surface of the sleeve seat 10 abuts against the mounting surface, so that the screw thread seat 20 is rotated to enable the other end of the screw thread seat 20 to penetrate through the abdicating open groove 11, then the other end of the screw thread seat is inserted between the screw rod 1 and the sleeve seat 10, and the internal thread of the screw thread seat 20 penetrates through the abdicating open groove 11 and then is tightly held with the external thread of the screw rod 1 to be in threaded fit through the positioning fit of the first positioning part and the second.
In this embodiment, the projection of the inner side surface of the threaded seat 20 on the bottom surface is an arc, and the diameter corresponding to the arc is smaller than the inner diameter of the sleeve seat 10. As shown in fig. 5, when the other end of the screw seat 20 is inserted between the screw 1 and the sleeve seat 10 and the first positioning portion and the second positioning portion are in positioning engagement, the inner side surface of the screw seat 20 is located in the inner side surface of the sleeve seat 10.
In this embodiment, the second positioning portion is a positioning groove 21 extending along the longitudinal direction of the threaded seat 20. The number of the positioning slots 21 may be designed to be plural, and is the same as the number of the positioning blocks 12, but not limited thereto.
In this embodiment, as shown in fig. 4, the positioning slot 21 includes a first slot sidewall 211, a slot sidewall 212, and a second slot sidewall 213, which are connected in sequence, and the top end of the first slot sidewall 211 and the top end of the second slot sidewall 212 are both connected to the inner side surface of the screw seat 20.
In this embodiment, the top ends of the first groove sidewall 211 and the second groove sidewall 212 are located on the same arc line projected from the bottom surface of the inner side surface of the threaded seat 20.
In this embodiment, the other end of the threaded seat 20 is provided with a guiding inclined surface 22.
In this embodiment, the outer side surface of the threaded seat 20 is provided with a toggle block 23.
In this embodiment, a fixing shaft 13 is disposed on an outer side surface of the sleeve seat 10, and bosses 14 are disposed at two ends of the fixing shaft 13; the outer side surface of the threaded seat 20 is further provided with a rotating sleeve 24 with an opening, and the rotating sleeve 24 is rotatably sleeved outside the fixed shaft 13 and located between the two bosses 14.
In this embodiment, the threaded seat 20 is made of a flexible material.
In the initial state, the screw seat 20 and the sleeve seat 10 are in the open state, as shown in fig. 1, when the quick-mounting nut and the screw rod 1 need to be quickly mounted, the sleeve seat 10 is sleeved outside the screw rod 1, and the top end face of the sleeve seat is abutted against the mounting table; then, the screw seat 20 is rotated to enable the other end of the screw seat to penetrate through the abdicating slot 11 and then to be inserted between the sleeve seat 10 and the screw rod 1, a certain deformation is generated under the elastic action of the screw seat 20 in the inserting process to enable the positioning block 12 to be clamped into the positioning slot 21, and after the positioning block 12 is completely clamped into the positioning slot 21, the internal thread of the screw seat 20 is just tightly held and in threaded connection with the external screw rod of the screw rod 1, so that the installation of the quick-assembly nut is completed.
When the quick-assembly nut needs to be disassembled, the toggle block 23 is pulled outwards only to enable the other end of the threaded seat 20 to be separated from the space between the screw rod 1 and the sleeve seat 10, meanwhile, the positioning block 12 is separated from the positioning groove 21, the quick-assembly nut is disassembled, and the sleeve seat 10 can be taken out of the screw rod 1.
The whole installation and disassembly process is very simple and convenient, and does not need to consume too much labor. And the whole quick-mounting nut structure is also extremely simple.
