Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more specifically, to a fastener with high stability. Background Art

[0002] Fasteners are a type of parts used to connect and fix parts, but they still have some shortcomings in actual use. For example, existing fasteners mainly include bolts. During the bolt fixing process, the vibration generated by the outside world will cause the bolts to loosen. If they are in such a state for a long time, it is easy for the bolts to fall off and separate from the object. In addition, existing bolts are usually an integrated structure with a relatively simple structure and lack of protection for the screw head. Therefore, when the bolts are installed, the screw heads are exposed to the air for a long time and are easily oxidized and corroded, thereby shortening the service life of the fasteners and affecting the stability of the fastener connection. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a fastener with high stability to solve the problems that the fasteners in the prior art are easily loosened due to vibration, and the screw heads are easily oxidized and corroded when exposed to the air.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a fastener with high stability, comprising

[0005] A bolt body, wherein the bolt body is configured as a hollow structure;

[0006] A mounting end, the mounting end is fixedly connected to the top end of the bolt body, and a limiting plate is arranged on the surface of the mounting end;

[0007] A screw head, which is arranged at the top end of the bolt body, and the interior of the screw head is in contact with the surface of the mounting end and the limiting plate;

[0008] A connecting rod, the top of which is fixedly connected to the top of the inner wall of the screw head, a fixing plate is fixedly installed on the bottom end of the connecting rod, a connecting column is arranged at the bottom of the fixing plate, and racks are arranged opposite to each other on both sides of the width direction of the connecting column.

[0009] It also includes a gear, a mounting rod, a flip plate, and a contact pad. The outer edge of the gear is meshed with the outer edge of the rack. The gear is fixedly mounted on the surface of the mounting rod. Both ends of the mounting rod are rotatably connected to the inner wall of the bolt body. The bottom of the flip plate is fixedly connected to the surface of the mounting rod, and the contact pad is arranged on the top of the flip plate.

[0010] Among them, it also includes an auxiliary component, which is arranged on the surface of the screw head.

[0011] Among them, the auxiliary component includes a covering sleeve, a movable ring, an extension sleeve, a fitting pad, and a rotating end. The covering sleeve is fixedly sleeved on the surface of the screw head, the movable ring is movably installed inside the covering sleeve, the bottom surface of the movable ring is fixedly connected to the top surface of the extension sleeve, the fitting pad is arranged on the bottom surface of the extension sleeve, and the rotating end is fixedly connected to the center of the top surface of the covering sleeve.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] In the above scheme, the bottom end of the bolt body is first placed at the connection, and then the bolt body is rotated as a whole, and the fastener is installed in the connection by using the thread structure. When the fastener is installed in place, the screw head is vertically moved upward, so that the fixing plate connected to the bottom end of the connecting rod and the connecting column can move synchronously. During the movement of the connecting column, the rack and the gear can mesh with each other, so that the flip plate is flipped through the meshing and moved out from the inside of the bolt body, driving the contact pad to abut against the inner wall of the connection, so as to perform secondary fixation on the fastener as a whole, so as to avoid the fastener from being loosened due to external vibration after installation, and ensure that the fastener can be tightly connected to the object;

[0014] By setting a covering sleeve on the outside of the screw head, the entire screw head can be covered. At the same time, when the screw head moves up, the extension sleeve together with the movable ring can be moved down as a whole to expand the coverage area of ​​the screw head by the covering sleeve, avoiding the screw head from being exposed to the air for a long time and being affected by corrosion and oxidation, thereby extending the service life of the fastener.

[0024] The screw head 4 is arranged at the top of the bolt body 1, and the interior of the screw head 4 is in contact with the surfaces of the mounting end 2 and the limiting plate 3;

[0025] A connecting rod 5, the top of which is fixedly connected to the top of the inner wall of the screw head 4, a fixing plate 6 is fixedly installed on the bottom end of the connecting rod 5, a connecting column 7 is arranged at the bottom of the fixing plate 6, and racks 8 are arranged opposite to each other on both sides of the connecting column 7 in the width direction.

[0026] It also includes a gear 9, a mounting rod 10, a flip plate 11, and a contact pad 12. The outer edge of the gear 9 is meshed with the outer edge of the rack 8. The gear 9 is fixedly mounted on the surface of the mounting rod 10. Both ends of the mounting rod 10 are rotatably connected to the inner wall of the bolt body 1. The bottom of the flip plate 11 is fixedly connected to the surface of the mounting rod 10. The contact pad 12 is arranged on the top of the flip plate 11. Through the contact pad 12, the flipping of the flip plate 11 can drive the contact pad 12 to contact the inner wall of the mounting bolt position of the object, thereby increasing the friction between the bolt as a whole and the bolt, so as to improve the fixing strength of the bolt.

[0027] It also includes an auxiliary component 13 which is arranged on the surface of the screw head 4 .

[0028] The auxiliary component 13 includes a covering sleeve 131, a movable ring 132, an extension sleeve 133, a fitting pad 134, and a rotating end 135. The covering sleeve 131 is fixedly sleeved on the surface of the screw head 4, the movable ring 132 is movably installed inside the covering sleeve 131, the bottom surface of the movable ring 132 is fixedly connected to the top surface of the extension sleeve 133, the fitting pad 134 is arranged on the bottom surface of the extension sleeve 133, and the rotating end 135 is fixedly connected to the center of the top surface of the covering sleeve 131. Through the provided fitting pad 134, the screw head 4 can be moved upward as a whole and contacted with the installation plane, thereby ensuring that the screw head 4 will not leak into the air and avoid oxidation corrosion.

[0029] The surfaces of the covering sleeve 131, the movable sleeve 132 and the extension sleeve 133 provided in this embodiment form a corrosion-resistant layer on the surface of the substrate by an electrochemical method. The electroplating coating provided can form a dense protective layer, which effectively isolates the substrate from oxygen and moisture in the environment, thereby preventing the substrate from oxidation and corrosion, thereby further improving the anti-oxidation and corrosion effect on the basis of covering and protecting the fasteners.

[0030] The working process of the utility model is as follows: first, the bottom end of the bolt body 1 is placed at the connection, and then the bolt body 1 is rotated as a whole, and the fastener can be installed in the connection by using the threaded structure. When the fastener is installed in place, the screw head 4 is moved vertically upward so that the fixing plate 6 connected to the bottom end of the connecting rod 5 and the connecting column 7 can move synchronously. During the movement of the connecting column 7, the rack 8 and the gear 9 can engage with each other, so that the flip plate 11 is flipped through the engagement and moved out from the inside of the bolt body 1, driving the contact pad 12 to abut against the inner wall of the connection to perform secondary fixation on the fastener as a whole.
