Description

Technical Field

[0001] This utility model relates to a nut structure, and more particularly to a nut that allows for quick installation. Background Technology

[0002] Many devices, equipment, or accessories require the use of threaded components such as screws, bolts, or threaded tubes. These components often need to be fastened with nuts. However, in many cases, the nut must rotate a long distance on the component to achieve the locking effect, which leads to several problems. For example, the long engagement time reduces the efficiency of the installation operation. If the installation space is small, it is even more difficult to rotate the nut for a long distance, and it may even be difficult to apply force, thus affecting the reliability of the lock.

[0003] To address the shortcomings of traditional nuts, Chinese utility model patent CN 206738362 U discloses a quick-tightening nut to solve the aforementioned problems. This nut includes a nut body with a threaded hole and a through hole. The threaded hole has a vertical axis, while the through hole has an inclined axis. The threads of the threaded hole and the through hole are coplanar and form an acute angle. The through hole design removes part of the thread in the threaded hole. In use, tilting the threaded hole allows the screw to be quickly inserted into place through the through hole. Finally, the nut is straightened, and the nut body is locked onto the screw through the threaded hole. This achieves the effect of quick nut assembly.

[0004] However, the structural design of this nut still has some drawbacks. For example, the screw hole is completely enclosed within the nut body. Therefore, the internal threads on the inner surface of the screw hole cannot be integrally formed using a mold through drafting. Instead, the screw hole and internal threads must first be machined from metal, and then a through hole is formed by drilling to remove part of the internal threads. As a result, the metal processing of the internal threads and through holes is limited, and it is not possible to integrally mold them from plastic materials. This restricts the manufacturing efficiency and forces the use of expensive metal materials, making it impossible to reduce manufacturing and material costs.

[0005] Although the nut is designed with a through hole to avoid the external threads of the screw, allowing the screw to pass through quickly, the closed through hole design also restricts the space available for the screw to avoid it. This limits the tilt angle of the nut. Therefore, when the nut must be designed to be relatively slender, the closed through hole design cannot provide enough space for avoidance. As a result, even at the maximum tilt angle, the external threads of the screw may still bite and contact the internal threads of the screw hole, causing the nut to be unable to move smoothly on the screw after tilting. Thus, its application range will be greatly limited. Utility Model Content

[0006] The main purpose of this utility model is to provide a quick-installation nut that can achieve a simple, labor-saving, fast and reliable installation and locking effect. It can be used in particular for the installation and locking of various faucets, toilets and other bathroom equipment or accessories.

[0007] To achieve the above objectives, this utility model provides a quick-installation nut, comprising:

[0008] A cylindrical body has an inlet end and an outlet end, and a cylindrical groove is formed inside, through which a screw-on component can pass. The cylindrical groove has a first side and a second side opposite to each other. A first internal thread is formed in part on the first side of the inner peripheral wall of the cylindrical groove, and an installation groove is formed on the second side of the inner peripheral wall of the cylindrical groove.

[0009] An elastic clamping block is installed and positioned in the mounting groove of the cylindrical body, and has a receiving part and at least one elastically deformable part abutting against the opposite part of the mounting groove. When the receiving part is subjected to force, it can force the elastic clamping block to move radially toward the center of the cylindrical groove and clamp the threaded part, thereby causing the first internal thread of the cylindrical body to move radially and engage with the threaded part. At the same time, the elastically deformable part generates elastic deformation and accumulates elastic restoring force.

[0010] A clamping ring is installed at the insertion end of the cylindrical body and can be restricted to move between an open position and a closed position along the axial direction of the cylindrical body. The ring has a through-hole, a clamping wall surface, and a stop position. The through-hole is opposite to the cylindrical groove of the insertion end and allows the threaded member to pass through and enter the cylindrical groove. After being abutted by the clamping wall surface, the clamping ring can move axially from the open position to the closed position and force the stop position to abut against the abutted part of the elastic clamping block, thereby actuating the first internal thread of the cylindrical body to engage with the threaded member.

[0011] The cylindrical body of the quick-install nut has an indented arc-shaped groove at its insertion end relative to the second side, which defines the installation groove. The arc-shaped groove has a notch relative to the center of the cylindrical groove, and a positioning wall is formed on each of the two inner walls of the arc-shaped groove on the two sides of the notch. The elastic clamping block has a clamping part and two elastic pieces that extend integrally from the two sides of the clamping part. The inner side of the clamping part has an arc-shaped clamping wall, which can fit and clamp the external thread of the threaded part through the notch. The outer side of the clamping part has the abutting part. The elastic pieces are used to form the elastic deformation part, which can abut and be positioned against the positioning wall.

[0012] A second internal thread is formed on the arc-shaped clamping wall of the quick-install nut, which can clamp and engage with the external thread of the threaded part together with the first internal thread of the cylindrical body.

[0013] The arc-shaped clamping wall of the quick-install nut is a plane that can abut against and clamp the external thread of the threaded component, and force the first internal thread of the cylindrical body to engage with the external thread of the threaded component alone.

[0014] The elastic clamping block of the quick-install nut has an abutting part that is an inclined wall surface; the clamping ring has a abutting block protruding on one side relative to the cylindrical body, the abutting block has an abutting position formed on the abutting block, the abutting position is an inclined wall surface, and it fits against the inclined wall surface of the elastic clamping block.

[0015] The elastic clamping block of the quick-install nut has an inclined wall surface as the abutting part; the clamping ring has an abutting block protruding on one side relative to the cylindrical body, and the abutting block has the abutting position formed on the abutting position, which is a spherical surface.

[0016] The cylindrical body of the quick-install nut has a plurality of limiting slots and at least one working wall at its insertion end; the clamping ring has a plurality of elastic hooks and at least one elastic foot; the elastic hooks can be elastically retracted and deformed to lock into the limiting slots, thereby restricting the clamping ring to move between the open and closed positions; the elastic foot can abut against the working wall when the clamping ring moves from the open position to the closed position, and generate elastic deformation to accumulate elastic restoring force.

[0017] The clamping ring of the quick-install nut has an elastic hook that abuts against the corresponding part of the limiting groove of the cylindrical body when the clamping ring moves from the open position to the closed position, and generates elastic deformation to accumulate elastic restoring force.

[0018] The cylindrical body of the quick-install nut has an engagement ring portion and a gripping ring portion extending from the engagement ring portion; the engagement ring portion has a first internal thread, an installation groove, and a portion of the cylindrical groove formed inside; the gripping ring portion has another portion of the cylindrical groove formed inside, and a gripping surface is formed on its outside for the user to grip and operate.

[0019] In this utility model nut, since the clamping ring of the nut is normally in the open position, the elastic clamping block is positioned by the elastic deformation of its two sides, and is located away from the center of the cylindrical groove of the cylindrical body. During installation, the screw can quickly pass along the axial direction of the cylindrical body between the first internal thread of the cylindrical body and the arc-shaped clamping wall or the second internal thread of the elastic clamping block. Therefore, the nut can easily and quickly move along the screw until the clamping wall of the clamping ring is abutted. With a slight application of force, the clamping ring can be moved from the open position to the closed position, and the elastic clamping block will also be moved away from the center of the cylindrical groove. The center of the groove moves radially closer to the center of the cylindrical groove, forcing the arc-shaped clamping wall on it to abut against and clamp the threaded part, or forcing the second internal thread on it to engage and clamp the external thread of the threaded part. At the same time, it can also drive the radial displacement of the cylindrical body, so that the first internal thread in its cylindrical groove can smoothly engage and clamp the external thread of the threaded part. In this way, the nut as a whole can be screwed with the screw. The installer only needs to slightly rotate the nut through the holding ring to tighten it, and can easily and quickly achieve the clamping and locking effect with one hand. Therefore, the overall locking operation of the nut and the threaded part is very simple, fast and firm, and the operation does not require tilting the nut for installation.

[0020] By using the first internal thread integrally formed by the cylindrical body as the main meshing structure, the meshing structure can be effectively ensured to have sufficient strength and firmness. There is no need to set the second internal thread on the elastic clamping block. It is only necessary to set the arc-shaped clamping wall to provide radial abutment clamping. Alternatively, the second internal thread can be set to further improve the strength and firmness of the overall meshing structure.

[0021] Since the nut does not need to be installed at an angle, it is particularly suitable for the installation and locking of various bathroom equipment or accessories such as faucets or toilets. It can significantly shorten the engagement time of long threads and improve the ease of installation, while ensuring the reliability and durability of the installation and locking.

[0022] The nut is not a one-piece molded component, but is assembled from a cylindrical body, an elastic clamping block and a clamping ring. Therefore, the components can be molded separately from plastic materials through a mold, making the production and manufacturing simple and fast, and also lightweight.

[0023] The nut can be designed with a structure that makes it easy for installers to hold and rotate it, such as the grip ring and the grip surface thereon. Therefore, it can achieve the effect of easy gripping and rotation and labor-saving operation. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 7 As shown, this utility model provides a preferred embodiment of a quick-installation nut 1, which can be screwed onto a threaded component, such as various types of bolts, screws, or threaded tubes, to quickly lock two objects together or together onto a third object. For example, as Figure 8 As shown, a first object 2 has a screw 2a at its bottom end, and a second object 3 has at least one mounting hole 3a through which the screw 2a can pass from top to bottom. The nut 1 can be quickly threaded onto the screw 2a and screwed onto the lower surface 3b of the second object 3, thereby forcing the lower surface 2b of the first object 2 to be tightly fixed to the upper surface 3c of the second object 3, thus quickly installing and locking the first object 2 onto the second object 3.

[0036] The first object 2 can be a common faucet assembly of various shapes or types, and its bottom end usually has at least one of the aforementioned screws 2a; the second object 3 can be a common sink or bathtub, etc., and the sink usually has at least one of the aforementioned mounting holes 3a.

[0037] The nut 1 in this embodiment includes a cylindrical body 10, an elastic clamping block 20, and a clamping ring 30; wherein:

[0038] like Figure 3 , 4 As shown, the cylindrical body 10 has an insertion end 11 and an exit end 12, and a cylindrical groove 13 is formed inside, through which the screw 2a can pass. The cylindrical groove 13 has a first side 131 and a second side 132 opposite to each other. A first internal thread 133 is formed in part on the first side 131 of the inner peripheral wall of the cylindrical groove 13, and an installation groove 134 is formed on the second side 132 of the inner peripheral wall of the cylindrical groove 13.

[0039] like Figure 2 , 3 As shown in Figure 6, the elastic clamping block 20 is installed and positioned in the mounting groove 134 of the cylindrical body 10, and has a receiving part 21 and at least one elastically deformable part 22 abutting against the opposite part of the mounting groove 134. When the receiving part 21 is subjected to force, it can force the elastic clamping block 20 to move radially toward the center of the cylindrical groove 13 and clamp the screw 2a, thereby causing the first internal thread 133 of the cylindrical body 10 to move radially and engage with the external thread of the screw 20a. At the same time, the elastically deformable part 22 generates elastic deformation and accumulates elastic restoring force. Using this elastic restoring force, after the abutting force of the receiving part 21 is released, the elastic clamping block 20 can be elastically radially reset and released from the screw 2a. At the same time, the first internal thread 133 of the cylindrical body 20 also releases from the screw 2a and disengages from the mutual engagement relationship.

[0040] like Figure 2 , 3 As shown in Figure 7, the clamping ring 30 is installed at the insertion end 11 of the cylindrical body 10 and can be restricted to move between an open position and a closed position along the axial direction of the cylindrical body 10. It has a through-hole 31, a clamping wall surface 32 and an abutment position 33. The through-hole 31 is opposite to the cylindrical groove 13 of the insertion end 11 and allows the screw 2a to pass through and enter the cylindrical groove 13. After the clamping wall surface 32 is abutted, the clamping ring 30 can move axially from the open position to the closed position and force the abutment position 33 to abut against the abutment portion 21 of the elastic clamping block 20, thereby causing the first internal thread 133 of the cylindrical body 10 to engage with the external thread of the screw 2a.

[0041] like Figure 3 As shown, the clamping wall 32 in this embodiment is composed of a plurality of radially distributed annular wall surfaces 320, but it is not limited thereto and can also be a complete annular wall surface.

[0042] like Figure 7 As shown, in this embodiment, the clamping ring 30 can be positioned in the closed position by forming a bottom ring wall 301 at the bottom of the clamping ring 30 and forming an upper ring edge 110 at the top of the cylindrical body 10 relative to the insertion end 11.

[0043] It should be noted that, such as Figure 2 , 8 As shown, when the clamping ring 30 is in the open position, it allows the screw 2a to quickly pass through the through-hole 31 of the clamping ring 30 and the cylindrical groove 13 of the cylindrical body 10. Therefore, during installation, the nut 1 can quickly move through the screw 2a. When the clamping wall surface 32 above the clamping ring 30 abuts against the lower surface 3b of the second object 3, the clamping ring 30 can be moved from the open position to the closed position. Figure 7 As shown, at this time, the elastic clamping block 20 can be moved radially to clamp the external thread of the screw 2a. It is easy to understand that the cylindrical body 10 will also be affected, causing its first internal thread 133 to engage with the external thread of the screw 2a, thus smoothly creating an engagement relationship. Accordingly, the installer only needs to slightly tighten the nut 1 to make the clamping wall 32 of the clamping ring 30 further adhere to and clamp the lower surface 3b of the second object 3, thereby quickly and firmly installing and locking the first object 2 onto the second object 3.

[0044] In this embodiment, as Figure 4 As shown, the insertion end 11 of the cylindrical body 10 has an indentation with an arc-shaped groove at the location relative to the second side 132, which defines the mounting groove 134. The arc-shaped groove has a notch 135 relative to the center of the cylindrical groove 13, and a positioning wall 136 is formed on each of the two inner walls of the arc-shaped groove on the two sides of the notch 135; Figure 2 , 6 As shown, the elastic clamping block 20 has a clamping portion 23 and two elastic pieces that extend integrally from two sides of the clamping portion 23. The inner side of the clamping portion 23 has an arc-shaped clamping wall 231, which can be fitted and clamped to the external thread of the screw 2a through the notch 135. The outer side of the clamping portion 23 has the abutment portion 21. The elastic pieces are used to form the elastic deformation portion 22, which can respectively abut and be positioned against the positioning wall 136.

[0045] Preferably, a second internal thread 232 is formed on the arc-shaped clamping wall 231, which can be clamped and engaged with the first internal thread 133 of the cylindrical body 10 to the external thread of the screw 2a.

[0046] It should be noted that the main function of the elastic clamping block 20 is to apply a radial pushing and clamping force to the opposite part of the screw 2a, thereby driving the cylindrical body 10 to move its first internal thread 133 radially and tightly engage with the external thread of the screw 2a, thus achieving the engagement effect. Therefore, the main engagement structure is composed of the first internal thread 133 and the external thread of the screw 2a. As for the elastic clamping block 20, the formation of the second internal thread 232 can further improve the engagement effect. If only a flat surface is formed on the arc-shaped clamping wall 231, such as... Figure 9 As shown, by simply using it to press against and tighten the screw 2a, the first internal thread 133 of the cylindrical body 10 can be forced to engage with the external thread of the screw 2a alone, which can still achieve the required engagement effect and meet the basic requirements.

[0047] In this embodiment, the abutting portion 21 of the elastic clamping block 20 is an inclined wall surface; the clamping ring 30 has an abutting block 34 protruding from one side relative to the cylindrical body 10, and the abutting block 34 has an abutting position 33 formed on the abutting block 34. The abutting position 33 is an inclined wall surface and fits against the inclined wall surface of the elastic clamping block 20. It is understood that the abutting position 33 of the abutting block 34 is not limited to an inclined wall surface, but can also be other common and feasible structural shapes, such as a spherical surface, such as... Figure 10 As shown.

[0048] In this embodiment, as Figure 4 , 5 As shown, the insertion end 11 of the cylindrical body 10 has a plurality of limiting slots 14 and at least one actuating wall 15; the clamping ring 30 has a plurality of elastic hooks 35 and at least one elastic foot 36; the elastic hooks 35 can elastically retract and deform to lock into the limiting slots 14, thereby restricting the clamping ring 30 to move between the open and closed positions; the elastic foot 36 can abut against the actuating wall 15 when the clamping ring 30 moves from the open position to the closed position, and generate elastic deformation to accumulate elastic restoring force. The elastic restoring force of the elastic foot 36, when the clamping force on the clamping wall 32 of the clamping ring 30 is released, ensures that the clamping ring 30 automatically returns from the closed position to the normally open position.

[0049] It is understandable that providing a plurality of grooves on the insertion end 11 of the cylindrical body 10, and providing the limiting grooves 14 and the actuating walls 15 on the outer groove walls of the grooves is a feasible implementation. In this embodiment, a total of four appropriately spaced limiting grooves 14 and four elastic hooks 35 relative to the limiting grooves 14 are provided, which can ensure the smoothness and stability of the assembly and movement between the clamping ring 30 and the cylindrical body 10. Two of the limiting grooves 14 can be formed on the outer groove walls of the two sides of the mounting groove 134, and the other two limiting grooves 14 are respectively provided on the outer groove wall of a first groove 140. In this embodiment, two appropriately spaced actuating walls 15 and two elastic feet 36 relative to the actuating walls 15 are provided on opposite sides of the mounting groove 134 or relative to the first side 131. The actuating walls 15 can be respectively formed on the outer groove wall of a second groove 150.

[0050] In this embodiment, the elastic hook 35 of the clamping ring 30 can abut against the corresponding part of the limiting groove 14 of the cylindrical body 10 when the clamping ring 30 moves from the open position to the closed position, and generate elastic deformation to accumulate elastic restoring force. The elastic restoring force of the elastic hook 35 functions approximately the same as the elastic restoring force of the elastic foot 36, ensuring that after the clamping force acting on the clamping wall 32 of the clamping ring 30 is released, the clamping ring 30 automatically and more smoothly returns to the normally open position from the closed position.

[0051] In this embodiment, the cylindrical body 10 has an engagement ring portion 101 and a gripping ring portion 102 extending from the engagement ring portion 101; the engagement ring portion 101 has a first internal thread 133, a mounting groove 134, and a portion of the cylindrical groove 13 formed inside; the gripping ring portion 102 has another portion of the cylindrical groove 13 formed inside, and a gripping surface 16 is formed on its outside, which can be gripped and rotated by a user to tighten or loosen the nut 1.

[0052] As can be seen from the above, if Figure 8As shown, since the clamping ring 30 of the nut 1 is normally in the open position, the elastic clamping block 20 is positioned by the elastic deformation parts 22 on both sides, and is located away from the center of the cylindrical groove 13 of the cylindrical body 10. During installation, the screw 2a can quickly pass along the axial direction of the cylindrical body 10 between the first internal thread 133 of the cylindrical body 10 and the arc-shaped clamping wall 231 or the second internal thread 232 of the elastic clamping block 20. In other words, the nut 1 can easily and quickly slide along the screw 2a until the clamping wall surface 32 of the clamping ring 30 abuts against the lower surface 3b of the second object 3. Then, with a slight force, the clamping ring 30 can be moved from the open position to the closed position. At this time, the elastic clamping block 20 will also be moved away from the cylindrical groove. The center of 13 moves radially closer to the center of the cylindrical groove 13, forcing the arc-shaped clamping wall 231 on it to abut against and clamp the outer thread of the screw 2a, or forcing the second inner thread 232 on it to engage and clamp the outer thread of the screw 2a. At the same time, it can also drive the radial displacement of the cylindrical body 10, so that the first inner thread 133 in the cylindrical groove 13 can smoothly engage and clamp the outer thread of the screw 2a. In this way, the nut 1 can be screwed with the screw 2a. The installer only needs to slightly rotate the nut 1 through the grip ring 102 to tighten it, and can easily and quickly achieve the clamping and locking effect with one hand, so that the first object 2 can be smoothly installed and locked to the second object 3. Therefore, the locking operation of the nut 1 and the screw 2a is quite simple, fast and firm. The operation process does not require tilting the nut 1 for installation.

[0053] It should be emphasized that by using the first internal thread 133 integrally formed by the cylindrical body 10 as the main meshing structure, the meshing structure can be effectively ensured to have sufficient strength and firmness. There is no need to set the second internal thread 232 on the elastic clamping block 20. It is only necessary to set the arc-shaped clamping wall 231 to provide radial abutment clamping. Of course, the second internal thread 232 can also be selected to further improve the strength and firmness of the overall meshing structure.

[0054] Since the nut 1 does not need to be installed at an angle, it is particularly suitable for the installation and locking of various bathroom equipment or accessories such as faucets or toilets. It can significantly shorten the screwing time of long threads and improve the ease of installation, while taking into account the reliability and durability of the installation and locking.

[0055] The nut 1 is not a one-piece molded component, but is assembled from a cylindrical body 10, an elastic clamping block 20 and a clamping ring 30. Therefore, the components can be molded from plastic materials through a mold, making the production and manufacturing simple and fast, and also lightweight.

[0056] The nut 1 can be designed with a structure that makes it easy for installers to hold and rotate it, such as the grip ring 102 and the grip surface 16 thereon, so as to achieve the effect of easy gripping and rotation and labor-saving operation.

[0057] The present invention has been described in detail above and embodiments have been cited. For those skilled in the art, it is obvious that various alternatives or modifications can be made based on the above description; therefore, all alternatives and modifications made on this basis are included within the spirit and scope of the claims.
