DETAILED DESCRIPTION

The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

As shown in Figures 1, 2, 3 and 4, an anti-deformation nut is provided, in which a main body 1 is rotatably connected to a threaded body 2, the threaded body 2 can slide and rotate in the main body 1, the threaded body 2 can extend out of the main body 1, the main body 1 is provided with a groove 4, the threaded body 2 is provided with an abutment 3, the abutment 3 can be engaged with the groove 4, and the abutment 3 can slide with the groove 4 along the length direction, and the two ends of the spring 5 respectively abut the main body 1 and the threaded body 2. The purpose of this design is that since the main body 1 and the threaded body 2 are two separate parts, the threaded body 2 is rotatably connected to the main body 1 and the threaded body 2 can slide inside the main body 1, since a groove 4 is provided inside the main body 1, a protrusion 6 is provided on the threaded body 2, and the protrusion 6 abuts against the groove 4, so that the main body 1 can be turned to The threaded body 2 inside the main body 1 rotates together. Since a spring 5 is provided inside the main body 1, the two ends of the spring 5 are respectively abutted against the threaded body 2 and the main body 1, and the threaded body 2 can extend out of the main body 1. When the threaded body 2 extending out of the main body 1 abuts against the fastener, or the threaded body 2 has been screwed to the end of the thread of the fastener, when the main body 1 is continued to be screwed, the threaded body 2 stops rotating due to resistance. Since the threaded body 2 cannot move forward due to resistance, the threaded body 2 extending out of the main body 1 moves into the main body 1, so that the abutment 3 is away from the groove and squeezes the spring 5 inside the main body 1. At this time, continuing to screw the main body 1 will cause the main body 1 to rotate idly while the threaded body 2 does not rotate, thereby avoiding deformation of the fastener and wear and deformation of the thread due to over-tightening.

The threaded body 2 is provided with a protrusion 6, and the spring 5 is respectively abutted against the protrusion 6 and the main body 1. The purpose of this design is to ensure that one end of the spring 5 can always abut against the threaded body 2 and the main body 1. When the threaded body 2 and the main body 1 slide up and down, the spring 5 will be squeezed. When there is no movement between the threaded body 2 and the main body 1, the function of the spring 5 is to keep the abutment 3 in abutment with the groove 4 when there is no external force, so that the stability of this product can be guaranteed when it is not in use, and the spring 5 also has the function of driving the abutment 3 to abut against the groove 4.

The main body 1 is provided with a groove 27 which can slide against the protrusion 6, and the groove 27 is inclined. The purpose of this design is that the groove 27 which slides against the protrusion 6 can make the protrusion 6 stuck in the groove 27 of the main body 1, so that the spring 5 is always in contact with the protrusion 6, so that the stability of the spring 5 inside the main body 1 is improved, and the spring 5 will not fall off due to factors such as transportation, making the main body 1 unusable, and the inclined groove 27 can make the protrusion 6 slide in the groove 27. When the threaded body 2 encounters resistance and cannot rotate, the protrusion 6 can slide upward along the groove 27 and squeeze the spring 5, so that the abutment 3 and the groove 1 4 are separated. When the abutment 3 is separated from the groove 1 4, the threaded body 2 will not rotate with the main body 1 when the user twists the main body 1. At this time, the inclined groove 27 plays a role in enabling the protrusion 6 to drive the threaded body 2 to move upward along the main body 1.

The inclination direction of groove 2 7 is the same as the direction of the thread and the inclination angle is greater than the helix angle of the threaded body 2. The purpose of this design is that this product is usually used in conjunction with bolts, and this product only needs to be screwed in one direction when in use. Therefore, the inclination direction of groove 2 7 must be the same as the direction of the thread, otherwise the product will be stuck and cannot be used. At the same time, the inclination angle of groove 2 7 must also be greater than the helix angle of the threaded body 2. When the inclination angle of groove 2 7 is greater than the helix angle of the threaded body 2, when the threaded body 2 is subjected to external force and cannot be tightened further, the protrusion 6 will slide along the inclination direction of groove 2 7, thereby causing the protrusion 6 to drive the threaded body 2 to move upward, causing the abutment 3 to move away from groove 1 4.

One end of the groove 2 7 is connected to the groove 3 8 which is annularly arranged in the body 1, and the protrusion 6 can slide in the groove 2 7 and/or the groove 3 8. The purpose of this design is that when the abutment member 3 and the groove 1 4 are no longer abutted, the protrusion 6 slides into the groove 3 8. Since the groove 3 8 is annularly arranged in the body 1, the protrusion 6 will slide along the groove 3 8. At this time, if the body 1 is rotated in the original direction, the body 1 will only idle, and the threaded body 2 cannot rotate with the body 1. If the user wants to unscrew this product, the user only needs to twist the body in the opposite direction. 1, since the protrusion 6 will slide in the groove three 8 at this time, when the user twists the body 1 in the opposite direction, there will be a period of idling. When the protrusion 6 reaches the junction of the groove two 7 and the groove three 8, under the elastic force of the spring 5 that drives the abutment 3 to approach the groove one 4, the protrusion 6 will tend to slide into the groove two 7. When the protrusion 6 slides along the groove two 7 to the end point, the abutment 3 will abut against the groove one 4. At this time, when the user rotates the body 1 in the opposite direction, the threaded body 2 will also rotate in the opposite direction, so that the product can be reused.

The main body 1 is provided with a welding portion 9, which divides the groove 2 7. The purpose of this design is that when this product is produced, the spring 5 needs to be installed first and the protrusion 6 and the groove 2 7 need to be abutted before assembly and welding, otherwise this product will not be able to be produced.
