Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a quick-install nut. Background Art
[0002] When installing a countertop faucet, the installation screw of the faucet body is inserted into the countertop, and the screw extending under the countertop is often locked by a nut. However, when locking, due to the small size of the nut and the small space under the countertop, it is difficult to use a wrench to lock the nut, or the wrench needs to be repeatedly re-stuck on the nut, which makes installation inconvenient and slow. For this reason, many quick-release nuts have appeared on the market. These quick-release nuts have a locking block that can be pressed to pop out. After the locking block pops out, it can hold the faucet screw through the thread. When disassembling, the locking block can automatically retract and release the faucet screw through the reset structure, which has the advantages of convenient and fast disassembly and assembly. However, the above-mentioned reset structure is often set on the hand-held seat of the quick-release nut, which makes the hand-held seat structure more complicated and difficult to form. For this reason, the present invention provides a quick-release nut structure that can solve the above-mentioned technical problems. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a quick-install nut structure with low molding difficulty.
[0004] A quick-install nut includes a hand-held seat, a locking block and a pressing seat, wherein:
[0005] The hand-held seat is tubular as a whole, with a head at one end and a mounting step surrounding the inner tube.
[0006] The locking block is arc-shaped, with a threaded inner concave surface. At least two locking blocks are circumferentially and movably mounted on the mounting step of the handle base, with the blocks having translational freedom toward and away from the central axis of the handle base. This allows the locking blocks to be positioned near the center of the handle base to clamp the faucet's screw, or to release the faucet's screw when disassembling.
[0007] The pressing seat is annular and movably mounted on the head end of the hand-held seat. A pushing structure and an elastic reset structure are provided between the pressing seat and the locking block.
[0008] During installation, the pressing seat presses against the bottom of the table, causing it to press. The pressing seat, through the pushing structure, forces the locking block to move toward the middle of the hand-held seat, causing the elastic return structure to deform. During disassembly, the pressing seat separates from the bottom of the table and is released. The elastic return structure then returns to its original position, forcing the locking block away from the middle of the hand-held seat.
[0009] The elastic reset structure of the quick-release nut provided by the utility model is arranged on the locking block and the pressing seat, avoiding the hand-held seat, so that the elastic reset structure is transferred from the installation step to the locking block and the pressing seat, forming an exposed state, which is easy to shape.
[0010] Preferably, the elastic reset structure includes a push surface and an elastic member, wherein the push surface is provided on one of the locking block and the pressing seat, and the elastic member is provided on the other of the locking block and the pressing seat. During installation, when the locking block moves toward the middle of the handheld seat, the push surface presses against the elastic member, and the elastic member is in a deformed state, thereby providing elastic force to push the locking block back into place during removal.
[0011] Preferably, the elastic member is an elastic rod, which is perpendicular to the moving direction of the locking block, has a simple structure and is easy to form.
[0012] Preferably, the elastic rod is arranged on the side of the pressing seat facing the hand-held seat, and the pushing surface is arranged at the end of the locking block, which is conducive to molding.
[0013] Preferably, in order to provide a balanced thrust, there are two sets of elastic reset structures between each locking block and the pressing seat, which are respectively arranged at both ends of the locking block.
[0014] Preferably, a slope is provided on the side of the end of the elastic rod facing the pushing surface, and the pushing surface is also a slope facing the elastic rod, which can avoid a sense of getting stuck or blocked.
[0015] Preferably, the pushing structure includes a first inclined surface and a second inclined surface, which is simple in structure and easy to form. The first inclined surface and the second inclined surface are respectively arranged on the locking block and the pressing seat and are opposite to each other. The pressing seat presses down and pushes the locking block toward the middle of the hand-held seat through the inclined surface.
[0016] Preferably, the mounting step is provided with a guide opening between the locking blocks, the guide opening being parallel to the axial direction of the hand-held seat, and the wall surface of the guide opening being provided with a limiting groove. The pressing seat is provided with a guide post inserted into the guide opening, and the end of the guide post is provided with an undercut that engages with the limiting groove, so that the pressing seat is movably mounted on the end of the movable seat through the undercut.
[0017] Preferably, the mounting step is provided with guide grooves at both ends of the locking block, the direction of the guide grooves being parallel to the line connecting the center of the locking block and the center of the handheld base. Guide strips are provided on the outer sides of both ends of the locking block, which slide within the guide grooves. Thus, the locking block is restrained by the guide strips and installed within the guide grooves, thereby preventing the locking block from deviating from the correct position during use.
[0018] Preferably, the outward side of the pressing seat is provided with a one-way tooth with a non-return function, which can effectively form a self-locking function and prevent the quick-release nut from loosening.
[0019] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:
[0020] The elastic reset structure of the quick-install nut provided by the utility model is arranged on the locking block and the pressing seat, avoiding the hand-held seat, so that the elastic reset structure is transferred from the installation step to the locking block and the pressing seat, forming an exposed state, which is easy to shape;
[0021] The elastic member is an elastic rod and is perpendicular to the moving direction of the locking block, with a simple structure and easy molding;
[0022] The pressing seat is movably mounted on the end of the movable seat by means of an inverted buckle, and the mounting structure is simple and can be quickly assembled and disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0036] See also Figures 1 to 9 A quick-install nut, comprising a hand-held seat 1, a locking block 2 and a pressing seat 3, wherein,
[0037] The handheld seat 1 is tubular as a whole, with a head at one end and a mounting step 11 surrounding the inner tube.
[0038] The locking block 2 is arc-shaped, with a threaded inner concave surface. At least two locking blocks 2 are movably mounted around the mounting step 11 of the handle base 1, with the ability to translate toward and away from the central axis of the handle base 1. This allows the locking block 2 to be positioned near the center of the handle base 1 to clamp the faucet's screw, or to release the faucet's screw when disassembling.
[0039] In one embodiment, the mounting step 11 is provided with guide slots 12 at both ends of the locking block 2. The direction of the guide slots 12 is parallel to the line connecting the center of the locking block 2 and the center of the handheld base 1. Guide bars 21 are provided on the outer sides of both ends of the locking block 2, which slide within the guide slots 12. The guide bars 21 thus constrain the locking block 2 to be installed within the guide slots 12, preventing the locking block 2 from deviating from the correct position during use.
[0040] The pressing seat 3 is annular and movably mounted on the head end of the hand-held seat 1. In one embodiment, the mounting step 11 is provided with a guide opening 13 between the locking blocks 2. The guide opening 13 is parallel to the axial direction of the hand-held seat 1 and has a retaining groove 14 on its wall. The pressing seat 3 is provided with a guide post that is inserted into the guide opening 13. The end of the guide post is provided with an undercut 31 that engages with the retaining groove 14. Thus, the pressing seat 3 is movably mounted on the end of the movable seat via the undercut 31.
[0041] A push-up structure and an elastic return structure are provided between the pressing seat 3 and the locking block 2. In this embodiment, the elastic return structure comprises a push-up surface 22 and an elastic member 32. The push-up surface 22 is provided on one of the locking block 2 and the pressing seat 3, while the elastic member 32 is provided on the other. During installation, when the locking block 2 moves toward the center of the handheld holder 1, the push-up surface 22 presses against the elastic member 32. The elastic member 32 is deformed, providing the elastic force to push the locking block 2 back into place during removal.
[0042] On the basis of the above embodiment, in another embodiment, the elastic member 32 is an elastic rod and is perpendicular to the moving direction of the locking block 2 , which has a simple structure and is easy to form.
[0043] Preferably, the elastic rod is positioned on the side of the pressing seat 3 facing the handle 1, and the pushing surface 22 is positioned at the end of the locking block 2, facilitating molding. Furthermore, the end of the elastic rod facing the pushing surface 22 is provided with an inclined surface, and the pushing surface 22 is also inclined toward the elastic rod, thereby preventing a sense of jamming or obstruction. Furthermore, to provide a balanced thrust, each locking block 2 and pressing seat 3 is provided with two sets of elastic reset structures, one at each end of the locking block 2.
[0044] In one embodiment, the push structure includes a first inclined surface 23 and a second inclined surface 33, which are simple and easy to form. The first inclined surface 23 and the second inclined surface 33 are respectively provided on the locking block 2 and the pressing seat 3, and are opposite to each other. The pressing seat 3 presses down and pushes the locking block 2 toward the middle of the handheld seat 1 via the inclined surfaces.
[0045] On the basis of the above embodiment, in one embodiment, a one-way tooth 34 with a reverse-stop function is provided on the outward side of the pressing seat 3 , which can effectively form a self-locking function and prevent the quick-release nut from loosening.
[0046] During installation, the pressing seat 3 presses against the bottom of the table, causing the pressing seat 3 to push the locking block 2 toward the middle of the hand-held holder 1 through the pushing structure, and causing the elastic return structure to deform. During removal, the pressing seat 3 separates from the bottom of the table and is released. The pressing seat 3, through the recovery of the elastic return structure, drives the locking block 2 away from the middle of the hand-held holder 1.
[0047] The elastic reset structure of the quick-release nut provided by the present invention is arranged on the locking block 2 and the pressing seat 3, avoiding the hand-held seat 1, so that the elastic reset structure is transferred from the installation step 11 to the locking block 2 and the pressing seat 3, forming an exposed state, which is easy to shape.
