Abstract
Description
Technical Field
[0001] The utility model relates to a nut structure, in particular to a nut which can be quickly installed. Background Art
[0002] In many devices, equipment or accessories, screws, bolts or screw tubes with long threads are required. These screw parts often have to be screwed and locked with nuts. However, in many cases, the nut must be rotated and moved on the screw part for a long distance to achieve the locking effect, which leads to some problems. For example, the screwing operation takes a long time, which reduces the efficiency of the installation operation. If the installation operation space is small, it is not conducive to the long-stroke rotation operation of the nut, and it is even difficult to apply rotation force, which affects the reliability of the locking.
[0003] In view of the shortcomings of the use of the above-mentioned traditional nuts, the utility model patent with Chinese authorization announcement number CN 219795808 U discloses a quick-install nut to solve the above-mentioned problems. The quick-install nut basically has an entry end, an exit end, a first half-shell-shaped screw-on portion relative to the entry end, and a second half-shell-shaped screw-on portion relative to the exit end and connected to the first screw-on portion; the first screw-on portion has a first hole groove, and a first internal thread formed on the inner surface of the first hole groove, and a first escape space is connected at the radial opening of the first hole groove; the second screw-on portion has a second hole groove, and a second internal thread formed on the inner surface of the second hole groove, and a second escape space is connected at the radial opening of the second hole groove, the second hole groove and the first hole groove are staggered along a central axis, so that the radial opening directions of the two differ by 180 degrees, and the first screw-on portion forms a tightening end wall.
[0004] The quick-install nut disclosed in the above utility model patent can be installed and applied to a variety of faucets or bathroom fixtures, and can be particularly applied to the installation of various types of toilets, such as side-lock toilets, all-inclusive toilets or bowel-exposed toilets, etc. The user can tighten or loosen the nut manually or with the help of a specific tool. One installation method is to pass two fixing bolts pre-assembled and fixed to a toilet flange from bottom to top through two opposite mounting holes on the bottom wall of the side-lock toilet, and then use two nuts to pass through the operating holes on the two side walls of the side-lock toilet, and quickly put them on each fixing bolt from top to bottom to perform a screw-locking operation, so that the side-lock toilet is quickly installed and locked on the toilet flange and the surrounding floor.
[0005] Another installation method is roughly the same as the above installation method, with the only difference being that an embedding portion is further configured on the periphery of the second threaded portion of the nut, and a plurality of slots are formed on the embedding portion so that the installer can use a turning tool, such as a flat-head or cross-head screwdriver, to pass through the operating hole of the side-lock toilet or the full-inclusive toilet and then embed and position it in any two relative slots for turning operations.
[0006] However, the design of the above-mentioned quick-install nut is still not perfect. For example, although the nut can be quickly put on each fixing bolt for screwing and locking operation, in the case of not directly manual operation or difficult manual operation, such as the case of turning the nut through a tool, it is difficult for the installer to stably control the nut in a vertical state after being aligned or guided through the tool. In addition, the nut does not have any mandatory alignment or guiding structure design, resulting in the nut still being tilted or shaken to varying degrees during the tool turning operation. Such tilting or shaking conditions will make it impossible for the first inner thread and the second inner thread of the nut to smoothly or effectively engage with the outer thread on the fixing bolt, thereby causing the screwing to be not smooth or the engagement to be incorrect. During the tightening process, it may also be necessary to use the operation of loosening, returning and tightening again many times before the locking operation can be successfully completed. In addition, the tightening operation will become very dependent on the installer's experience or operating feel. Therefore, it is extremely necessary to further improve the simplicity and stability of the operation to make it more in line with humanized operating demands. Utility Model Content

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0032] like Figures 1 to 4 As shown, the utility model provides a first embodiment of a quick-install nut. The nut 10 can be used to cooperate with a screw-fitting member such as a bolt 1 or the like to quickly lock two objects together, or to lock them together on a third object.
[0033] Furthermore, the nut 10 has a hole slot 11 extending along an axis X1, an opening 12 connected to the hole slot 11, and at least one positioning spring 13 protruding from the inside; the hole slot 11 is formed with a section of internal thread 111 relative to the opening 12, so that the bolt 1 passing through the opening 12 transversely into the hole slot 11 can be elastically resisted by the positioning spring 13, such as Figure 4 As shown, it meshes with the internal thread 111.
[0034] In this embodiment, the nut 10 has a cylindrical wall 101, and the cylindrical wall 101 has a threaded section 102 and a positioning section 103 located above the threaded section 102; the threaded section 102 is formed with the hole groove 11 and a lower opening 121 for forming a part of the opening 12; the positioning spring piece 13 is formed on the positioning section 103, and an upper opening 122 is formed for forming another part of the opening 12.
[0035] In this embodiment, the cylindrical wall 101 of the positioning section 103 protrudes two positioning springs 13 radially and symmetrically inward, and the positioning springs 13 define the upper opening 122 between each other. The minimum width of the upper opening 122 is smaller than the body diameter of the bolt 1, so that the bolt 1 entering the upper opening 122 can elastically open the positioning springs 13 and then enter the hole groove 11.
[0036] It should be noted that the present embodiment designs two symmetrical positioning spring pieces 13, which can achieve a relatively stable and even elastic resistance effect. However, it is still a feasible technical solution to achieve a similar elastic resistance effect using a single positioning spring piece 13 with a special shape design. Therefore, the present embodiment is not limited to the two positioning spring pieces 13, and the single positioning spring piece 13 is still within the scope of protection claimed by the present embodiment.
[0037] Secondly, the positioning spring 13 protrudes radially inward from the cylindrical wall 101. The radial protrusion does not mean protruding precisely in the radial direction or the axis X1 direction. In principle, it only needs to protrude roughly in the radial direction or the axis X1 direction to usually meet structural and functional requirements.
[0038] In this embodiment, the ends of the positioning spring pieces 13 are respectively formed with a top arc surface 131 , which can be elastically pressed against the outer thread of the bolt 1 in a matching manner.
[0039] In this embodiment, a chamber 14 is defined inside the cylindrical wall 101 of the positioning section 103 . The inner diameter of the chamber 14 is larger than the hole 11 , and the positioning spring 13 protrudes into the chamber 14 .
[0040] In this embodiment, the cylindrical wall 101 has an opposing top end 15 and a free end 16; the top end 15 is opposite to the screwing section 102 and is formed with a tightening end wall 151 for abutment; the free end 16 is opposite to the positioning section 103 and protrudes from the end of the cylindrical wall 101 to surround a plurality of blocks 161, and a slot 162 for inserting and turning a tool is defined between any two of the blocks 161. The tool can be a long object, a rod-shaped object, or a common tool such as a flathead screwdriver or a cross screwdriver.
[0041] As described above, the nut 10 of this embodiment can be used in conjunction with a screw-in part such as a bolt 1 or the like to quickly lock two objects together, or to lock them together on a third object, and can be particularly applied to various faucets or bathroom equipment. Taking a fully-inclusive toilet as an example, the nut 10 can be inserted through the operating holes on the left and right side walls of the toilet, and then directly use lateral movement to align its opening 12 and insert it into the bolt 1 that is pre-locked on a toilet flange and extends upward from the mounting hole on the bottom wall of the toilet. During the process, the bolt 1 will elastically expand the positioning spring sheet 13 and enter the hole 11 of the nut 10, as shown in FIG. Figure 4As shown, the arc surface 131 at the end of the positioning spring piece 13 is elastically pressed against the bolt 1, so that the bolt 1 can be stably and securely engaged with the internal thread 111 in the hole groove 11, and the nut 10 can be effectively prevented from tilting or shaking. In this way, the installer can use a tool to pass through the operating hole and insert it into any two suitable and opposite grooves 162 on the free end 16 of the nut 10 to perform a turning operation, so as to easily and smoothly lock the nut 10 on the bolt 1, and use the tightening end wall 151 on the top end 15 of the nut 10 to tighten it to the bottom wall of the toilet, so as to achieve the effect of firmly locking the toilet on the toilet flange.
[0042] like Figures 5 to 10 As shown, the utility model further provides a second embodiment of a quick-install nut. Compared with the nut 10 of the first embodiment, the nut 20 can provide a different assembly method by utilizing a slight structural design difference. That is, the nut 10 of the first embodiment allows the installer to directly insert it into the bolt 1 horizontally, while the nut 20 of this embodiment allows the installer to insert it into the bolt 1 at an appropriate tilt angle and then align it for assembly. Therefore, the assembly method is slightly different, but the tightening operation after assembly is roughly the same.
[0043] Specifically, the nut 20 of the present embodiment has a first hole groove 21, a second hole groove 22, a first opening 23 connected to the first hole groove 21, a second opening 24 connected to the second hole groove 22, and at least one positioning spring 25 protruding from the inside, which are staggered and spaced from each other along an axis X2; a first internal screw thread 211 is formed on the first hole groove 21 relative to the first opening 23, and a second internal screw thread 221 is formed on the second hole groove 22 relative to the second opening 24, so that the bolt 1 that is relatively inclined and sequentially passes through the first opening 23, a partition groove 26 formed between the first hole groove 21 and the second hole groove 22, and the second opening 24 can enter the first hole groove 21 and the second hole groove 22 synchronously after being guided, as shown in FIG. Figures 8 to 10 As shown, the first inner screw thread 211 and the second inner screw thread 221 are meshed with each other due to the elastic resistance of the positioning spring piece 25 .
[0044] In this embodiment, the nut 20 has a cylindrical wall 201, and the cylindrical wall 201 has a threaded section 202 and a positioning section 203 located above the threaded section 202; the threaded section 202 is formed with the first hole groove 21, the second hole groove 22, the partition groove 26, the first opening 23, and a lower opening 241 for forming a part of the second opening 24; the positioning spring piece 25 and an upper opening 242 are formed on the positioning section 203 for forming another part of the second opening 24.
[0045] In this embodiment, the cylindrical wall 201 of the positioning section 203 protrudes two positioning springs 25 radially and symmetrically inward, and the positioning springs 25 define the upper opening 231 between each other. The minimum width of the upper opening 231 is smaller than the body diameter of the bolt 1, so that the bolt 1 entering the upper opening 231 can elastically open the positioning springs 25 and then enter the first hole groove 21 and the second hole groove 22.
[0046] In this embodiment, the ends of the positioning spring pieces 25 are respectively formed with a top arc surface 251 , which can be elastically pressed against the outer thread of the bolt 1 in a matching manner.
[0047] In this embodiment, a chamber 27 is defined inside the cylindrical wall 201 of the positioning section 203 . The inner diameter of the chamber 27 is larger than the first hole 21 and the second hole 22 , and the positioning spring 25 protrudes into the chamber 27 .
[0048] In this embodiment, the cylindrical wall 201 has an abutting top end 28 and a free end 29 opposite to each other; the abutting top end 28 is opposite to the threaded section 202, and is formed with a tightening end wall 281 for abutting against; the free end 29 is opposite to the positioning section 203, and protrudes from the end of the cylindrical wall 201 to form a plurality of blocks 291, and a slot 292 for inserting a tool to turn is defined between any two of the blocks 291.
[0049] The nut 20 of this embodiment can also cooperate with the bolt 1 or other screw-in parts or the like to quickly lock two objects together, or to lock them together on a third object, and can be particularly applied to various faucets or bathroom equipment. Still taking the all-inclusive toilet as an example, the nut 20 can be inserted into the operation holes on the left and right side walls of the toilet, and then tilted appropriately, such as Figure 8 As shown, after the end of the bolt 1 is aligned with the first opening 23 of the nut 20, it can pass through the partition groove 26 and the lower opening 241 of the second opening 24 in sequence from the first opening 23, as shown in FIG. Fig. 9 As shown, then, the nut 20 is guided or adjusted so that the nut 20 is parallel to the bolt 1, as shown in FIG. Fig.10As shown, in this way, the bolt 1 can rotate and swing relatively through the first opening 23, the lower opening 241 and the upper opening 242 of the second opening 24, and the positioning spring piece 25 is elastically expanded and expanded, and simultaneously enters the first hole groove 21 and the second hole groove 22, and the top arc surface 251 at the end of the positioning spring piece 25 elastically presses against the bolt 1, so that the bolt 1 can be stably and securely engaged with the first internal thread 211 in the first hole groove 21 and the first internal thread 211 in the second hole groove 22. The second inner thread 221 is formed on the nut 20, thereby effectively preventing the nut 20 from tilting or shaking. Accordingly, the installer can use a tool to pass through the operating hole and insert it into any two suitable and opposite grooves 292 on the free end 29 of the nut 20 for turning operation, thereby easily and smoothly locking the nut 20 on the bolt 1, and using the tightening end wall 281 on the top end 28 of the nut 20 to tighten it to the bottom wall of the toilet. Similarly, the toilet can be securely locked on the toilet flange.
[0050] As can be seen from the above, the quick-install nut of the utility model, whether it adopts the assembly method of the first embodiment in which the nut 10 is moved horizontally and inserted, or the assembly method of the second embodiment in which the nut 20 is first tilted at an appropriate angle and then inserted and then guided, can be matched with the positioning spring pieces 13, 25 thereon to ensure that after the nuts 10, 20 are initially assembled and inserted or inserted into the bolt 1, it can ensure that the nuts 10, 20 can be stably and securely maintained in a good meshing state with the bolt 1 during the tightening operation, without worrying about tilting or shaking during the tightening operation, resulting in difficulty in effective meshing, or having to be overcome by loosening and then tightening the operation method, thereby achieving a simple, smooth, fast and secure locking effect.
[0051] The utility model has been described in detail above and embodiments have been cited. It is obvious that a person skilled in the art can make various alternatives or modifications according to the above description; therefore, all alternatives and modifications made on this basis are included in the spirit and scope of the claims.
