Description

Technical Field

[0001] The invention relates to a bolt-nut connecting fastener, in particular to a quick-install nut which can be quickly connected with a bolt. Background Art

[0002] As we all know, nuts and bolts are used in the fields of construction, electrical engineering, machinery, etc. to fasten components or equipment. According to the needs of the application, nuts have various structural forms, but the disadvantage of most existing nuts is that they cannot be installed quickly, or even if they can be installed quickly, the idle stroke during the tightening of the nuts is long, and it takes a long time to tighten. Especially during the installation of faucets and countertops, the limited installation space makes the screw connection of nuts and bolts more inconvenient. Therefore, quick-install nuts came into being.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN203129257U and the patent name of a faucet quick assembly and disassembly structure can realize the quick assembly and disassembly of the screw rod, but it has many parts, a complex structure, and the assembly process is time-consuming and laborious. It is necessary to improve the existing quick nut structure. Summary of the invention

[0004] The present invention provides a quick-install nut, which overcomes the shortcomings of the background technology. The technical solution adopted by the present invention to solve the technical problem is:

[0005] Quick-release nut, comprising:

[0006] A hollow sleeve, which is sleeved outside the screw rod, and a side wall of which is provided with a recessed groove and at least one first positioning portion;

[0007] A threaded seat with an internal thread, one end of which is hingedly connected to the sleeve, and the threaded seat is provided with at least one second positioning portion that can cooperate with the first positioning portion;

[0008] When the sleeve is sleeved outside the screw and its top surface is against the installation surface, the threaded seat is rotated to allow the other end of the threaded seat to pass through the paving groove and then be inserted between the screw and the sleeve, and the first positioning part and the second positioning part are positioned to cooperate so that the internal thread of the threaded seat passes through the paving groove and is tightly threadedly engaged with the external thread of the screw to achieve quick installation.

[0009] In a preferred embodiment, the projection of the inner side surface of the threaded seat on the bottom surface is an arc shape, and the diameter corresponding to the arc shape is smaller than the inner diameter of the sleeve.

[0010] In a preferred embodiment: the first positioning portion is a positioning block extending along the longitudinal direction of the sleeve; the second positioning portion is a positioning groove extending along the longitudinal direction of the threaded seat.

[0011] In a preferred embodiment: the positioning groove includes a first groove side wall, a groove bottom wall and a second groove side wall connected in sequence, the top of the first groove side wall and the top of the second groove side wall are both connected to the inner side surface of the threaded seat; the clearance groove extends along the circumference of the sleeve, and the positioning block is located in the clearance groove.

[0012] In a preferred embodiment: the top of the first groove side wall and the top of the second groove side wall are both located on the same arc line of the projection of the bottom surface of the inner side of the threaded seat; the inner side of the positioning block and the inner side of the clearance groove are located on the same circumferential surface.

[0013] In a preferred embodiment: the other end of the threaded seat is provided with a guiding slope.

[0014] In a preferred embodiment: a toggle block is provided on the outer side of the threaded seat.

[0015] In a preferred embodiment: a fixed shaft is provided on the outer side of the sleeve seat, and bosses are provided at both ends of the fixed shaft; a rotating sleeve with an opening is also provided on the outer side of the threaded seat, and the rotating sleeve is rotatably connected to the outside of the fixed shaft and is located between the two bosses.

[0016] In a preferred embodiment: the threaded seat is made of a flexible material.

[0017] Compared with the background technology, this technical solution has the following advantages:

[0018] 1. When quick installation is required, first place the sleeve outside the screw and place its top surface against the installation surface. Then, rotate the threaded seat to insert the other end of the threaded seat through the clearance slot and insert it between the screw and the sleeve seat. Then, through the positioning cooperation of the first positioning part and the second positioning part, the internal thread of the threaded seat passes through the clearance slot and is tightly threaded with the external thread of the screw. Since the other end of the threaded seat is inserted between the screw and the sleeve seat, and the threaded seat can always remain stable and motionless under the positioning cooperation of the first positioning part and the second positioning part, the stability is increased while maintaining tightness. Moreover, the quick-install nut has a simple structure, is easy to use, and is fast. Compared with traditional quick-install nuts, the quick-install nut of the present invention can greatly reduce production costs and is suitable for popularization and use.

[0019] 2. The projection of the inner side of the threaded seat on the bottom surface is an arc shape, and the diameter corresponding to the arc shape is smaller than the inner diameter of the sleeve seat, so that the internal thread of the threaded seat can be tightly embraced with the external thread of the screw to avoid the loosening phenomenon caused by the lack of contact between the two.

[0020] 3. The first positioning part is a positioning block, and the second positioning part is a positioning groove. The structures of the two positioning parts are relatively simple and the positioning and matching are relatively convenient.

[0021] 4. The top ends of the side walls of the first groove and the second groove are both located on the same circular arc line of the bottom surface projection of the inner side surface of the threaded seat; the inner side of the positioning block and the inner side of the relief slot are located on the same circumferential surface, which can ensure that the positioning block is always located in the positioning groove when the internal thread of the threaded seat is tightly held with the external thread of the screw rod, further ensuring the stable cooperation between the threaded seat and the screw rod.

[0022] 5. The inner side surface of the other end of the threaded seat is provided with a guiding inclined surface, which plays a guiding role when the other end of the threaded seat is inserted between the threaded seat and the screw rod.

[0023] 6. The threaded seat is made of a flexible material such as rubber. When the positioning groove and the positioning block are in positioning cooperation, they can be well matched only through the elastic deformation of the threaded seat itself. Description of the Drawings

The relief slot 11 extends circumferentially along the socket 10, and the positioning block 12 is located in the relief slot 11. AsFigure 3 As shown, the circumferential arc length of the sleeve 10 occupied by the clearance 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 cooperate with the screw 1.

[0035] The number of the positioning block 12 is set to one, and the positioning block 12 divides the clearance slot 11 into two. According to needs, the number of the positioning block 12 can also be two or three, but is not limited thereto.

[0036] In this embodiment, Figure 2 As shown, the inner side of the positioning block 12 and the inner side of the clearance groove 11 are located on the same circumferential surface.

[0037] One end of the threaded seat 20 is hingedly connected to the sleeve 10, and the threaded seat 20 is provided with at least one second positioning portion that can cooperate with the first positioning portion; when the sleeve 10 is sleeved outside the screw 1 and its top surface is against the mounting surface, the threaded seat 20 is rotated to allow the other end of the threaded seat 20 to pass through the clearance groove 11 and then be inserted between the screw 1 and the sleeve 10, and through the positioning cooperation of the first positioning portion and the second positioning portion, the internal thread of the threaded seat 20 passes through the clearance groove 11 and is tightly threadedly cooperated with the external thread of the screw 1 to achieve quick installation.

[0038] In this embodiment, the projection of the inner side surface of the threaded seat 20 on the bottom surface is an arc shape, and the diameter corresponding to the arc shape is smaller than the inner diameter of the sleeve seat 10. Figure 5 As shown, when the other end of the threaded seat 20 is inserted between the screw rod 1 and the sleeve 10 and the first positioning portion is positioned and matched with the second positioning portion, the inner side surface of the threaded seat 20 is located inside the inner side surface of the sleeve 10.

[0039] In this embodiment, the second positioning portion is a positioning groove 21 extending longitudinally along the threaded seat 20. The number of the positioning grooves 21 can be designed to be multiple, the same as the number of the positioning blocks 12, but is not limited thereto.

[0040] In this embodiment, Figure 4 As shown, the positioning groove 21 includes a first groove side wall 211 , a groove bottom wall 212 and a second groove side wall 213 connected in sequence, and the top of the first groove side wall 211 and the top of the second groove side wall 212 are both connected to the inner side surface of the threaded seat 20 .

[0041] In this embodiment, the top of the first groove side wall 211 and the top of the second groove side wall 212 are both located on the same arc line of the projection of the bottom surface of the inner side surface of the threaded seat 20 .

[0042] In this embodiment, a guiding inclined surface 22 is disposed at the other end of the threaded seat 20 .

[0043] In this embodiment, a toggle block 23 is disposed on the outer side of the threaded seat 20 .

[0044] In this embodiment, a fixed shaft 13 is provided on the outer side of the sleeve 10, and bosses 14 are provided at both ends of the fixed shaft 13; a rotating sleeve 24 with an opening is also provided on the outer side of the threaded seat 20, and the rotating sleeve 24 is rotatably connected to the outside of the fixed shaft 13 and located between the two bosses 14.

[0045] In this embodiment, the threaded seat 20 is made of a flexible material.

[0046] In the initial state, the threaded seat 20 and the sleeve seat 10 are in an open state. Figure 1 As shown, when the quick-release nut and the screw rod 1 need to be quickly installed, it is only necessary to first place the sleeve 10 on the outside of the screw rod 1 with its top end against the installation table; then, rotate the threaded seat 20 so that the other end thereof passes through the accommodating slot 11 and is inserted between the sleeve 10 and the screw rod 1. During the insertion process, the threaded seat 20 undergoes a certain deformation under the elastic action of the threaded seat 20 itself so that the positioning block 12 is inserted into the positioning slot 21. When the positioning block 12 is completely inserted into the positioning slot 21, the internal thread of the threaded seat 20 and the external screw of the screw rod 1 are tightly threaded together, and the installation of the quick-release nut is completed.

[0047] When disassembly is required, it is only necessary to pull the toggle block 23 outward to disengage the other end of the threaded seat 20 from between the screw rod 1 and the sleeve 10, and at the same time, the positioning block 12 leaves the positioning groove 21, and the disassembly of the quick-release nut is completed. At this time, the sleeve 10 can be taken out of the screw rod 1.

[0048] The entire installation and disassembly process is very simple and convenient, and does not require much effort. The entire quick-release nut structure is also extremely simple.

[0049] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
