Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically a quick-assembly bolt. Background Technology

[0002] Bolts are a common type of mechanical fastener, widely used in machinery manufacturing, construction engineering, transportation and other fields. They are simple in structure, easy to install and reliable in connection. They are mainly composed of three parts: head, shank and thread. The head is used to apply torque, the shank bears tensile or shear force, and the thread achieves the fastening function by cooperating with the nut. In the field of mechanical assembly, bolt connection is the most basic fastening method, and its assembly efficiency and reliability directly affect the overall performance of the equipment.

[0003] However, it still has some drawbacks, such as poor tool compatibility, various bolt and nut sizes in complex mechanical structures, special wrenches required for different specifications of bolts, and inconvenience in installation due to frequent changes in assembly tools.

[0004] To address the aforementioned issues, this application proposes a quick-assembly bolt. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly bolt to solve the problem of strong coupling between tool and bolt specifications mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick-assembly bolt, including a bolt head, a bolt assembly size control device installed above the bolt head, an anti-slip pad installed on the outer surface of the bolt assembly size control device, and a bolt rod fixedly connected below the bolt head. The bolt assembly size control device facilitates the use of the same fastening tool to fasten nuts and threads on bolts of different sizes in different environments by adjusting the extension length of the rotating telescopic area adjustment plate.

[0007] Preferably, a threaded rod is fixedly connected to the lower end of the bolt rod.

[0008] Preferably, the lower end of the threaded rod is detachable from the internal thread groove, which is located inside the nut.

[0009] Preferably, a rotating limiting plate is installed below the bolt assembly size control device, and a linkage rod is fixedly connected below the bolt assembly size control device.

[0010] Preferably, the linkage is equipped with a gear, and toothed plates mesh on both sides of the gear. A limit plate is fixedly connected to one end of the toothed plate, and a rotating telescopic area adjustment plate is fixedly connected to the other end of the toothed plate.

[0011] Preferably, the toothed plates are provided in two sets and mirror images of each other. The linkage rod is movable inside the bolt head, and the rotating telescopic area adjustment plate is movable on both sides of the bolt head. This is a bolt assembly size control device for a quick-assembly bolt. By adjusting the telescopic length of the rotating telescopic area adjustment plate, bolts of different sizes can be fastened to nuts and threads using the same fastening tool in different environments. The rotation of the bolt assembly size control device drives the linkage rod and gear 9 to rotate. At the same time, the gear meshes with the two sets of toothed plates, causing one end of the rotating telescopic area adjustment plate to move back and forth. The two sets of rotating telescopic area adjustment plates extend out as force points for the assembly tool. After fastening, the bolt assembly size control device is rotated in the opposite direction, causing the rotating telescopic area adjustment plate to retract into the bolt head.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the bolt assembly size control device, facilitates universal assembly by adjusting the telescopic length of the rotating telescopic area adjustment plate, allowing bolts of different specifications to be used with the same wrench in different environments.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4A quick-assembly bolt includes a bolt head 1, a bolt assembly size control device 6 installed above the bolt head 1, an anti-slip pad 7 installed on the outer surface of the bolt assembly size control device 6, and a bolt rod 2 fixedly connected below the bolt head 1. By adjusting the extension length of the rotating telescopic area adjustment plate 12 through the bolt assembly size control device 6, bolts of different sizes can be fastened to nuts and threads using the same assembly tool in different environments.

[0021] In this embodiment, as shown... Figures 1-2 As shown, a threaded rod 3 is fixedly connected to the lower end of the bolt rod 2. The lower end of the threaded rod 3 is detachable from the internal thread groove 5, which is located inside the nut 4.

[0022] In this embodiment, as shown... Figures 3-4 As shown, a rotating limiting plate 13 is installed below the bolt assembly size control device 6. A linkage rod 8 is fixedly connected below the bolt assembly size control device 6. A gear 9 is installed on the linkage rod 8. Gear plates 10 mesh on both sides of the gear 9. A limiting plate 11 is fixedly connected to one end of the gear plate 10, and a rotating telescopic area adjustment plate 12 is fixedly connected to the other end of the gear plate 10. Two sets of gear plates 10 are provided and mirror-correspond to each other. The linkage rod 8 moves inside the bolt head 1, and the rotating telescopic area adjustment plate 12 moves on both sides of the bolt head 1. The bolt assembly size control device 6 rotates, driving the linkage rod 8 and the gear 9 to rotate. At the same time, the gear 9 meshes with the two sets of gear plates 10, driving one end of the rotating telescopic area adjustment plate 12 to move back and forth. The two sets of rotating telescopic area adjustment plates 12 extend out as force points for the assembly tool. After tightening, the bolt assembly size control device 6 is rotated in the opposite direction, causing the rotating telescopic area adjustment plate 12 to retract into the bolt head 1.

[0023] Working principle

[0024] A bolt assembly size control device 6 for quick-assembly bolts achieves universal assembly by adjusting the telescopic length of the rotating telescopic area adjustment plate 12. This allows bolts of different sizes to be fastened to nuts and threads using the same assembly tool in different environments. The bolt assembly size control device 6 rotates, driving the linkage rod 8 and gear 9 to rotate. Simultaneously, the gear 9 meshes with two sets of toothed plates 10, causing one end of the rotating telescopic area adjustment plate 12 to move back and forth. The two sets of rotating telescopic area adjustment plates 12 extend to serve as the force points for the assembly tool wrench. After tightening, rotating the bolt assembly size control device 6 in the opposite direction causes the rotating telescopic area adjustment plate 12 to retract into the bolt head 1.
