[0020] 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.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fastener that is easy to disassemble and assemble in this embodiment includes a bolt and a main body. The main body is composed of a number of independent nut bodies 1 cut along the central axis of the threaded hole. An abutment plate 2 is provided on one side of the main body. A hole 3 with a diameter larger than the threaded hole is formed in the center of the abutment plate 2. A slider 4 that is slidably connected to the abutment plate 2 is provided on the side of the main body close to the abutment plate 2. The abutment plate 2 is rotatably provided with a push rod 5 that can drive the nut body 1 to slide in the direction of the central axis of the abutment plate 2. The end of the push rod 5 away from the nut body 1 extends out of the side of the abutment plate 2 away from the main body.

[0022] When using this product, the user inserts the bolt into the mounting plate and then fits the nut. Since the spacing between the nut bodies 1 is larger than the diameter of the bolt under normal conditions, the user can directly sleeve the main body along the length direction of the bolt until the end of the push rod 5 extending out of the main body abuts against the mounting plate. At this time, the user pushes the main body toward the mounting plate to rotate the push rod 5, thereby causing the push rod 5 to drive the nut body 1 to slide toward the central axis of the bolt, thereby causing the nut body 1 to slide to the joint with the bolt, and then slightly rotate the nut body 1 to tighten the thread of the nut body 1 with the thread of the bolt to complete the installation, thereby solving the problem of complicated installation of the bolt and nut.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, one end of the push rod 5 abuts against the side wall of the nut body 1 to form a force transmission end 6, and the other end extends out of the abutment plate 2 to form a force applying end 7. The middle section of the push rod 5 is rotationally connected to the abutment plate 2, and the force applying end 7 is arranged on the side of the rotational connection with the abutment plate 2 away from the abutment plate 2. The force transmission end 6 is arc-shaped, and the force applying end 7 is arranged parallel to the abutment plate 2.

[0024] When this product is in use, when the user pushes the main body to slide to the point where the force-applying end 7 abuts the mounting plate, the user continues to push the main body toward the mounting plate, so that the force-applying end 7 is subjected to a vertical downward thrust from the mounting plate, thereby causing the push rod 5 to rotate along the middle section and the rotational connection with the abutment plate 2, thereby causing the force-transmitting end 6 to rotate toward the center axis of the hole 3 to be horizontal with the abutment plate 2, thereby applying a thrust toward the center axis of the hole 3 to the nut body 1. When the nut body 1 is pushed to the point where it cooperates with the mating bolt, the force-applying end 7 rotates to be parallel to the abutment plate 2, so that the abutment plate 2 is completely fitted with the mounting plate, and the force-transmitting end 6 is in an arc shape, thereby preventing the force-transmitting end 6 from getting stuck when it rotates.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a slide groove 8 is formed on the side of the abutment plate 2 close to the nut body 1, and the slider 4 slides in the slide groove 8. A clamping groove 9 is formed on the slide groove 8 close to the central axis of the abutment plate 2. The slider 4 can be limitedly connected with the clamping groove 9. A spring 10 that can make the slider 4 slide toward the abutment plate 2 is fixed in the nut body 1 on the side of the slider 4 away from the abutment plate 2, and the side wall of the slider 4 can abut against the inner wall of the clamping groove 9.

[0026] When the product is in use, when the push rod 5 rotates to slide the nut body 1 to the position where it cooperates with the bolt, the user rotates the main body in the tightening direction to prompt the nut body 1 to fit the bolt thread toward the mounting plate, so that the mounting plate pushes the force-applying end 7 to continue to rotate. When the nut body 1 is rotated and tightly fitted with the bolt, the abutment plate 2 and the mounting plate are tightly fitted, and the force-applying end 7 is rotated to be parallel to the side of the abutment plate 2 close to the mounting plate. The slider 4 slides along the slide groove 8 to the card groove 9. The slider 4 is pushed by the spring 10 and slides into the card groove 9, so that the slider 4 cannot slide, thereby completing the tightening installation and achieving the effect of quick installation.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a reset rod 11 extending out of the nut body 1 away from the abutment plate 2 is fixedly provided on the side of the slider 4 away from the abutment plate 2, a force plate 12 is formed on the end of the reset rod 11 away from the slider 4, and an anti-slip strip 13 is formed on the side of the force plate 12 away from the threaded hole.

[0028] When the product is in use, when the user needs to disassemble it, the user can use a tool to clamp the force plate 12 and push it away from the mounting plate, so that the tool abuts the anti-slip strip 13 and applies a thrust in the direction away from the mounting plate to the anti-slip strip 13, prompting the reset rod 11 to slide in the direction away from the slot 9, thereby driving the slider 4 to slide out of the slot 9. At this time, the user applies a rotational force to the force plate 12 in the direction of loosening the main body. At this time, the user applies a rotational force to the force end 7 in the direction of the mounting plate with his other hand, and at the same time releases the clamping force on the force plate 12, prompting the nut body 1 to slide in the direction away from the central axis of the bolt, so that the distance between the nut bodies 1 is greater than the diameter of the bolt. The user can directly slide the main body along the length direction of the bolt to complete the disassembly, thereby achieving the effect of quick disassembly.

[0029] like Figure 1 and Figure 2 As shown, a groove 14 having a diameter larger than that of the hole 3 is formed on the side of the abutment plate 2 away from the nut body 1 .

[0030] When this product is used, in order to disperse the pressure and increase the reliability of the connection after installation, a gasket is often added between the nut and the bolt. During installation, the user can place a suitable gasket in the groove 14 to prevent the gasket from moving during the fitting process, which would reduce the effect.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
