Description

Technical Field

[0001] The utility model relates to the technical field of nut fastening, in particular to a nut fastening device. Background Art

[0002] Super nuts are mainly used in applications that require high torque and high locking force. Super nuts are high-strength fasteners whose design features include a special geometric shape to generate greater friction when tightening, and multiple locking elements to evenly distribute the load when subjected to high torque, thereby improving the tightening performance. This nut can effectively prevent loosening and falling off, providing a more reliable connection. The main structure of the super nut is to evenly process several small screw holes around the large nut and install a push screw. The existing method is mostly to use an ordinary torque wrench to tighten the push screw, thereby tightening the large nut.

[0003] Chinese utility model CN219747792U discloses a super nut fastening device, which designs a super nut fastening structure. The principle is to drive the driven gear to rotate through the active gear, so that the first sleeve and the second sleeve rotate, and the first bolt and the second bolt are rotated to connect with the super nut and tighten them.

[0004] However, the thread directions of the two thread grooves on most existing super nuts are the same, which means that when the first bolt and the second bolt are rotated, they must also be rotated in the same direction. In order to connect with the super nut, but the directions of the first sleeve and the second sleeve driven by the meshing of the driving gear and the driven gear are opposite, which cannot be used to tighten most super nuts, so it is less practical. Therefore, in response to the above-mentioned problems, a method is designed that can simultaneously control the same direction rotation of sleeve one and sleeve two to tighten the bolts.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] Super nuts are mainly used in applications that require high torque and high locking force. Super nuts are high-strength fasteners whose design features include a special geometric shape to generate greater friction when tightening, and multiple locking elements to evenly distribute the load when subjected to high torque, thereby improving the tightening performance. This nut can effectively prevent loosening and falling off, providing a more reliable connection. The main structure of the super nut is to evenly process several small screw holes around the large nut and install a push screw. The existing method is mostly to use an ordinary torque wrench to tighten the push screw, thereby tightening the large nut.

[0033] In the related art, the driving gear drives the driven gear to rotate, so that the first sleeve and the second sleeve rotate, and the first bolt and the second bolt are rotated to connect with the super nut and tighten. However, the thread directions in the two thread grooves on most existing super nuts are the same, which means that when the first bolt and the second bolt are rotated, they must also be rotated in the same direction. Only in this way can they be connected with the super nut, but the directions of the first sleeve and the second sleeve driven by the meshing of the driving gear and the driven gear are opposite, which cannot be used to tighten most super nuts, so it is less practical.

[0034] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a nut fastening device. When it is necessary to fasten the super nut 11, only the sleeve one 22 and the sleeve two 24 above the housing 14 need to be sleeved on the bolt one 12 and the bolt two 13. At this time, the electric drill is connected to the bottom end of the vertical rod one 21. The electric drill drives the vertical rod one 21 to rotate, and at the same time drives the gear one 25 to rotate. While the gear one 25 rotates, it meshes with the gear two 27 to drive the gear two 27 to rotate. At the same time, the gear two 27 meshes with the gear three 28 to drive the gear three 28 to rotate. At this time, the rotation directions of the gear one 25 and the gear three 28 are the same. At the same time, the vertical rod one 21 and the vertical rod two 23 rotate together and in the same rotation direction, driving the sleeve one 22 and the sleeve two 24 to rotate, and the bolt one 12 and the bolt two 13 can be rotationally installed on the super nut 11 for fastening the super nut.

[0035] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0036] Combined with Figures 1 - 5 , the embodiment of the present application provides a nut fastening device, including; a super nut 11 with a bolt one 12 arranged inside; a bolt two 13 arranged inside the super nut 11; a housing 14 arranged below the super nut 11; a rotating assembly 2 is arranged inside the housing 14, and the rotating assembly 2 includes: a vertical rod one 21 arranged inside the housing 14, and both ends penetrate the inner side wall of the housing 14 and are rotatably connected to the housing 14; a sleeve one 22 is arranged at the top of the vertical rod one 21; the bottom of the vertical rod two 23 penetrates the outer side wall of the housing 14 and is inserted into the inside and rotatably connected to the inner side wall of the housing 14; a sleeve two 24 is arranged at the top of the vertical rod two 23; a gear one 25 is fixedly sleeved on the outer side wall of the vertical rod one 21; a connecting rod 26 is arranged inside the housing 14, and the bottom is rotatably connected to the inner side wall of the housing 14; a gear two 27 is fixedly sleeved on the outer side wall of the connecting rod 26 and meshes with the gear one 25; a gear three 28 is fixedly sleeved on the outer side wall of the sleeve one 22 and meshes with the gear two 27.

[0037] Specifically, the bottom end of the vertical rod one 21 can be connected to the output shaft of the electric drill by means of a card slot, so that the electric drill drives the vertical rod one 21 to rotate. The super nut 11 is a high-strength fastener, and its design features include adopting a special geometric shape to generate greater friction during fastening, and adopting multiple locking elements to evenly distribute the load when bearing large torque, thereby improving the fastening performance.

[0038] When in use and when it is necessary to tighten the super nut 11, only the sleeve one 22 and the sleeve two 24 above the housing 14 need to be sleeved on the bolt one 12 and the bolt two 13. At this time, connect the electric drill to the bottom end of the vertical rod one 21, drive the vertical rod one 21 to rotate through the electric drill, and at the same time drive the gear one 25 to rotate. While the gear one 25 is rotating, it will mesh with the gear two 27 to drive the gear two 27 to rotate. At the same time, the gear two 27 will mesh with the gear three 28 to drive the gear three 28 to rotate. At this time, the rotation directions of the gear one 25 and the gear three 28 are the same, and at the same time, the vertical rod one 21 and the vertical rod two 23 rotate together and in the same rotation direction, driving the sleeve one 22 and the sleeve two 24 to rotate, and the bolt one 12 and the bolt two 13 can be rotationally installed on the super nut 11 to tighten the super nut 11.

[0039] In some embodiments, the number of the sleeve one 22 can be correspondingly set according to the specific number of the bolt two 13 on the super nut 11.

[0040] When in use, the same number of the bolt two 13 and the sleeve one 22 can enable all the bolt two 13 to be installed on the super nut 11 while tightening the super nut 11.

[0041] In some embodiments, the outer side walls of the tops of the bolt one 12 and the bolt two 13 are attached to the inner side walls of the sleeve one 22 and the sleeve two 24.

[0042] When in use, the attached design can make the connection between the bolt one 12 and the bolt two 13 and the sleeve one 22 and the sleeve two 24 closer, and it is not easy to slip when driving the bolt one 12 and the bolt two 13 to rotate.

[0043] In some embodiments, both the vertical rod two 23 and the sleeve two 24 are connected by a buckle.

[0044] Specifically, the sleeve two 24 can be disassembled through the buckle connection. The principle of the buckle connection is mainly based on simple mechanical principles. Through the design of the positioning part and the fastening part, the embedded connection or overall locking of parts is realized.

[0045] When in use, the sleeve two 24 can be disassembled by the buckle connection method, which is convenient for replacing the sleeve two 24 that matches the bolt two 13.

[0046] In some embodiments, the rotating assembly 2 further includes: a plurality of convex strips 29 are provided on the outer side wall of the housing 14.

[0047] When in use, the setting of the convex strips 29 can increase the friction when grasping the housing 14, thereby reducing the occurrence of slipping.

[0048] In some embodiments, the outer side walls of the sleeve 1 22 and the sleeve 2 24 are both cylindrical in design.

[0049] The cylindrical design has a smooth surface when in use, which can reduce scratches between them when rotating.

[0050] In some embodiments, rectangular grooves 31 are provided at the upper and lower ends of the vertical pole 21, and a rectangular block 32 is provided at the bottom of the sleeve 22. The rectangular block 32 is inserted into the rectangular groove 31, and the sleeve 22 can be installed on one end of the vertical pole 21.

[0051] When in use, the sleeve 1 22 can be disassembled and installed at the bottom of the vertical pole 1 21, and the rectangular block 32 can be inserted into the rectangular groove 31. At this time, the electric drill can be connected to the top of the vertical pole 1 21 to drive the vertical pole 1 21 to rotate so that the sleeve 1 22 and the bolt 1 12 can be tightened, or the sleeve 1 22 can be disassembled and the vertical pole 1 21 can be rotated by the electric drill, and the vertical pole 23 can be rotated through the transmission of the gear 2 27 and the gear 3 28 to control the sleeve 2 24 to rotate and tighten the bolt 2 13 alone. It can be operated according to the actual situation.

[0052] In some embodiments, a magnetic block 33 is disposed at the bottom of the rectangular block 32 , and the magnetic block 33 is magnetically attracted to the inner wall of the rectangular groove 31 .

[0053] During use, the magnetic block 33 can be arranged so that when the rectangular block 32 is inserted into the rectangular groove 31 , the magnetic block 33 and the inner wall of the rectangular groove 31 are attracted to stabilize the position of the rectangular block 32 so that the rectangular block 32 will not be easily separated from the rectangular groove 31 .

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0055] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
