[0002] Fasteners, also known as standard parts in the market, are mechanical components that can mechanically fix or snap together two or more components. They are characterized by a wide variety of varieties and specifications, different performance and uses, and a high degree of standardization, serialization, and generalization, including fasteners with snap-fit ​​structures.

[0003] However, the existing fasteners with a snap-fit ​​structure do not have high strength, and thus cannot meet people's usage needs.

[0004] For example, Chinese patent publication number CN213929094U discloses a fastener with a snap-fit ​​structure, which solves the problem that existing fasteners with a snap-fit ​​structure do not have high strength and therefore cannot meet people's usage needs.

[0005] However, when this structure is actually used, existing fasteners, such as bolts and nuts, need to be operated with the help of tools such as wrenches. Once the wrench is forgotten, the fastener cannot be installed normally. In addition, during actual use, once vibration occurs, the nut is easily loosened, resulting in poor fastening effect. In view of this, the present invention proposes a fastener with a snap-fit ​​structure. Utility Model Content

[0008] It can be seen that in the above structure, one end of the screw is passed through the surface of the object to be fastened, and the hexagonal nut is rotated on the thread outside the screw to achieve the fastening effect of the object. The fastening pad can improve the tightness of the fastener to a greater extent.

[0009] In order to be able to rotate and tighten the fastener in the absence of tools such as wrenches, preferably, the two outer walls of the hexagonal screw head and the hexagonal nut are provided with an auxiliary rotation structure, and the auxiliary rotation structure includes a rotating shaft, and the two outer walls of the hexagonal screw head and the hexagonal nut are provided with rectangular grooves, and the rotating shaft is rotatably installed inside the rectangular groove, a sleeve is fixedly provided on the surface of the rotating shaft, and a sleeve rod is slidably provided inside the sleeve, and the two inner walls of the rectangular groove are provided with shaft holes, and shaft pins are fixedly provided at both ends of the rotating shaft, and the shaft pins are tightly rotated and connected inside the shaft hole.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As attached Figure 1-4 The fastener of the snap-fit ​​structure shown includes a hexagonal screw head 1, a screw rod 2 is fixedly provided at one end of the hexagonal screw head 1, a fastening pad 3 is provided on the outside of the screw rod 2, a hexagonal nut 4 is provided on the outside of the screw rod 2 on one side of the fastening pad 3, the fastening pad 3 is movably sleeved on the outside of the screw rod 2, and the hexagonal nut 4 is threadedly connected to the screw rod 2.

[0022] Specifically, in this structure, the fastener of the snap-fit ​​structure is composed of a hexagonal screw head 1, a screw 2 fixed to one end of the hexagonal screw head 1, a fastening pad 3 movably sleeved on the screw 2, and a hexagonal nut 4 threadedly installed on the screw 2. During the specific fastening, one end of the screw 2 is passed through the surface of the object to be fastened, and the hexagonal nut 4 is threadedly rotated on the outside of the screw 2 to achieve the fastening effect of the object. The fastening pad 3 is made of rubber material, which can improve the tightness of the fastener to a greater extent.

[0023] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown in Figures 3 and 4, the two outer walls of the hexagonal screw head 1 and the hexagonal nut 4 are provided with an auxiliary rotation structure, which includes a rotating shaft 5. The two outer walls of the hexagonal screw head 1 and the hexagonal nut 4 are provided with a rectangular groove 6. The rotating shaft 5 is rotatably installed inside the rectangular groove 6. A sleeve 7 is fixedly provided on the surface of the rotating shaft 5, and a sleeve rod 8 is slidably provided inside the sleeve 7. A shaft hole 13 is provided on the two inner walls of the rectangular groove 6. A shaft pin 14 is fixedly provided at both ends of the rotating shaft 5, and the shaft pin 14 is tightly rotatably connected inside the shaft hole 13.

[0024] Specifically, in this structure, when the hexagonal screw head 1 and the hexagonal nut 4 are rotated, the rotating shaft 5 rotates tightly inside the shaft hole 13 through the shaft pin 14, and the sleeve 7 and the sleeve rod 8 inside the rectangular groove 6 can be rotated from the vertical state to the horizontal state. At this time, the sleeve 7 and the sleeve rod 8 are rotated out from the inside of the rectangular groove 6 and are in a horizontal state. The operator extends the sleeve rod 8 from the inside of the sleeve 7 to a certain length according to the actual situation, and then can rotate the hexagonal screw head 1 and the hexagonal nut 4 respectively by holding the sleeve rod 8 or the sleeve 7 to achieve the tightening of the object. This structure can perform tightening operations in the absence of tools such as wrenches. At the same time, a wrench can also be used to rotate the hexagonal screw head 1 and the hexagonal nut 4;

[0025] The sleeve rod 8 can be shortened inside the sleeve 7 and rotated inside the rectangular groove 6 through the rotating shaft 5, so that the shortened sleeve 7 or sleeve rod 8 can be re-stored into the rectangular groove 6 without affecting normal use.

[0026] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, a cover plate 9 is provided at one end of the screw rod 2, a threaded column 10 is provided at one end of the cover plate 9, a threaded hole 11 is provided at the end of the screw rod 2, the threaded column 10 is threadedly connected to the threaded hole 11, and a stop rod 12 is fixedly provided at the top and bottom of the threaded column 10 at one end of the cover plate 9. The lengths of the stop rod 12, the threaded column 10 and the threaded hole 11 are all set to be the same, and one end of the stop rod 12 is attached to the surface of the hexagonal nut 4.

[0027] Specifically, in this structure, in order to prevent the hexagonal nut 4 on the screw rod 2 from loosening due to the vibration of the buckling structure, specifically, after the hexagonal nut 4 is threadedly installed on the screw rod 2 to tighten the object, the operator threadedly connects the threaded column 10 at one end of the cover plate 9 with the threaded hole 11 on the screw rod 2. When the threaded column 10 is threadedly rotated to the end of the threaded hole 11, the two stop rods 12 on the cover plate 9 are pressed against the surface of the hexagonal nut 4. Once vibration occurs, the threaded position of the threaded column 10 and the threaded hole 11 is limited, so that the stop rod 12 limits the displacement of the hexagonal nut 4 outside the screw rod 2, thereby improving the fastening effect of the fastener;

[0028] It is worth noting that the length of the stop rod 12, the threaded column 10 and the threaded hole 11 needs to meet the distance that the hexagonal nut 4 moves on the external thread of the screw 2 to ensure that the stop rod 12 can resist the hexagonal nut 4. It can be customized according to the specific situation.

[0029] Working principle of this utility model:

[0030] The present application provides a fastener with a snap-fit ​​structure. When in use, one end of a screw rod 2 is passed through the surface of an object to be fastened, and the object is fastened by rotating a hexagonal nut 4 on the outside of the screw rod 2. The fastening pad 3 is made of rubber material, which can greatly improve the tightness of the fastener.

[0031] When the hexagonal screw head 1 and the hexagonal nut 4 are rotated in the absence of a wrench tool, the rotating shaft 5 rotates tightly inside the shaft hole 13 through the shaft pin 14, and the sleeve 7 and the sleeve rod 8 inside the rectangular groove 6 are rotated from the vertical state to the horizontal state. According to the actual situation, the sleeve rod 8 is extended from the inside of the sleeve 7 to a certain length. Then, the hexagonal screw head 1 and the hexagonal nut 4 can be rotated respectively by holding the sleeve rod 8 or the sleeve 7 to achieve the tightening of the object. A wrench can also be used for fixing;

[0032] After the hexagonal nut 4 is threadedly installed on the screw rod 2 to tighten the object, the threaded column 10 at one end of the cover plate 9 is threadedly connected to the threaded hole 11 on the screw rod 2, so that the two stop rods 12 on the cover plate 9 are against the surface of the hexagonal nut 4. Once vibration occurs, the stop rods 12 limit the displacement of the hexagonal nut 4 outside the screw rod 2 due to the threaded limitation of the threaded column 10 and the threaded hole 11, thereby improving the fastening effect of the fastener.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
