Description

Technical Field

[0001] The utility model relates to the field of bolts, in particular to a durable stop eye bolt. Background Technique

[0002] Eye bolts, also known as hole bolts in China, are widely used in: low-temperature and high-pressure valves, pressure pipelines, fluid engineering, oil drilling and production equipment, oilfield equipment and other fields, and are often used in occasions or tools where connections are disassembled, such as the valve industry, folding bicycles, and baby carriages. Because eye bolts are convenient and fast to use, they play a role in connecting and fastening when used with matching nuts, and have a very wide range of applications.

[0003] For example, the patent with the authorization announcement number CN221097155U applied by our company earlier discloses a fixed eye bolt, which includes a screw rod and a nut that are cooperatively arranged. The screw rod includes a screw rod section, a smooth shaft section, and an annular part. Among them, the annular part, the screw rod section, and the smooth shaft section are arranged in sequence from top to bottom. The surface of the screw rod section is provided with external threads. The smooth shaft section is located below the screw rod section and the diameter of the smooth shaft section is smaller than that of the screw rod section. A movable groove is vertically opened along the radial direction at the lower end of the smooth shaft section, and a pin is fixedly connected in the movable groove, and a clamping part is movably connected to the pin.

[0004] The above patent realizes the stop of the nut through the clamping part, ensuring the firmness of the use of the eye bolt; compared with the method of drilling holes and adding pins on the stud, the fixing method of the present utility model is more reliable, and at the same time, the present utility model can be disassembled and assembled repeatedly; however, the disadvantage of the above patent is that during use, since the clamping block itself is small and there are only two of them, the stop effect of the clamping part can be ensured during the first few times of repeated disassembly and assembly. However, as the number of uses increases or decreases, when the nut is rotated downward, the card slot on the nut itself will hit the clamping block, and a single clamping block is prone to wear and deformation, resulting in the failure of the stop effect.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above defects. Summary of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5 , a durable stop turnbuckle bolt, comprising a screw rod 1 and a nut 2 which are arranged in cooperation with each other.

[0024] Similar to a fixed turnbuckle bolt previously applied by our company in the background art, likewise, the screw rod 1 includes a screw rod section 101, a smooth shaft section 102 and an annular part 103, wherein the annular part 103, the screw rod section 101 and the smooth shaft section 102 are arranged in sequence from top to bottom. External threads are provided on the surface of the screw rod section 101. The smooth shaft section 102 is located below the screw rod section 101 and the diameter of the smooth shaft section 102 is smaller than that of the screw rod section 101.

[0025] As Figures 3-5 shown, in this embodiment, two receiving grooves 3 are symmetrically opened at the lower end of the smooth shaft section 102. A stop plate 301 is rotatably arranged in the receiving grooves 3. The stop plate 301 is generally comma-shaped. At the same time, the shape of the receiving grooves 3 is similar to that of the stop plate 301.

[0026] The stop plate 301 includes a stop part 302 and a rotating part 303. The rotating part 303 is generally circular. The stop part 302 extends from the rotating part 303. A countersunk hole 304 is opened at the center of the rotating part 302. A connecting pin 305 is arranged in the countersunk hole 304 of the rotating part 302. The connecting pin 305 passes through the countersunk hole 304 and is fixedly connected to the bottom of the receiving groove 3, and the rotating part 302 is rotatably connected to the connecting pin 305.

[0027] At the same time, the receiving groove 3 is provided with a boss 306 at a position corresponding to the rotating portion 302; at least three clamping blocks 307 are evenly spaced at the top of the stopper portion 302.

[0028] Similarly, one side of the block 307 is inclined, and the other side is vertically arranged;

[0029] At the same time, the height of the boss 306 is consistent with or slightly greater than the height of the block 307; the boss 306 is mainly used to prevent the block 307 from being blocked when the stop plate 301 is received in the receiving groove 3, so that the block 307 can enter the receiving groove 3;

[0030] At the same time, the inner side of the stopper portion 302 of the stopper plate 301 is also provided with an edge chamfer 308, so as to facilitate the movement of the stopper plate 301;

[0031] In this embodiment, a plurality of slots 201 are provided in a circular array on the bottom end of the nut 2, and the slots 201 are matched with the block 307;

[0032] like Figures 6-7 As shown, when the bolt of the present solution is put into use, the stop plate 301 is first received in the receiving groove 3, and the outer wall of the stop plate 301 is aligned with the outer wall of the optical axis section 102, and the stop plate 301 will not prevent the nut 2 from entering the screw rod; nor will it prevent the screw rod from passing through the mounting surface 900;

[0033] The screw rod 1 is screwed through the threaded hole of the mounting surface 900, and then the nut 2 is screwed into the bolt 1 at the other end of the mounting surface 900, and the nut is completely passed through the optical axis section 102.

[0034] Then rotate the stop plate 301 90 degrees. At this time, the stop plate 301 is blocked by the inner wall of the receiving groove 3 and cannot continue to rotate. Then slightly rotate the nut 2 downward so that the block 307 is stuck in the groove 201, thereby preventing the nut 2 from rotating.

[0035] The downward rotation direction of the nut 2 is consistent with the direction of rotating the stop plate 301 in the above step. If the nut continues to rotate downward, the nut will not be blocked by the stop plate 301, and the stop plate 301 will be blocked by the receiving groove 3, and the nut cannot continue to rotate.
