[0002] Hardware fittings refer to various metal accessories used to fasten and connect two or more parts in construction, furniture manufacturing, mechanical equipment installation and other fields. They usually include screws, nuts, washers, rivets, pins, hinges, latches, buckles and other types.

[0003] Most of the existing traditional hardware fasteners cannot quickly self-lock, and usually require additional manual steps after assembly to ensure secure locking. This makes the actual operation process inconvenient and may also cause insufficient locking due to human factors, thereby reducing the reliability of the hardware fastener connection. Utility Model Content

[0004] In view of this, the utility model provides a hardware connector with a self-locking structure, which can achieve the effect of locking by tightening through the coordinated cooperation of the self-locking mechanism and the self-locking mechanism, and can effectively prevent the nut from rotating counterclockwise. It can also achieve self-locking when connecting hardware of different thicknesses, ensuring that the hardware is stable and not loose, enhancing the reliability of the connection of the hardware connector, realizing convenient self-locking and unlocking operations, and improving the safety and practicality of the hardware connector.

[0005] In order to solve the above technical problems, the utility model provides a hardware connecting piece with a self-locking structure, including a bolt and a nut threadedly connected to the lower end of the bolt, a self-locking mechanism is also provided between the nut and the bolt, the self-locking mechanism includes a rectangular mounting groove arranged at the front end of the outer arc surface of the bolt, a ratchet plate is provided on the rear wall of the rectangular mounting groove, the lower end surface of the nut is rotatably connected to a limiting collar, the boss on the limiting collar is cooperated with the rectangular mounting groove, a sliding limiting clamp is slidably connected in a limiting groove arranged in the middle part of the rear surface of the limiting collar, the rear end of the sliding limiting clamp is cooperated with the ratchet plate, a spring is provided between the rear wall surface of the sliding limiting clamp and the front wall surface of the limiting groove in which it is located, and an unlocking component for pushing the sliding limiting clamp to move is also provided at the front end of the bolt.

[0006] The rear end of the sliding limit clamp is arranged to be tilted downward from front to rear.

[0007] The unlocking component includes a rectangular slide groove arranged on the rear wall of the rectangular mounting groove, a top plate is slidably connected in the rectangular slide groove, a rectangular through-hole adapted to the top plate is opened in the middle of the ratchet plate, a rectangular slot is arranged in the front end of the upper end face of the bolt, the rectangular slot is connected with the rectangular slide groove, a spring 2 is arranged at the lower end of the rear wall of the rectangular slide groove and the upper end of the rear wall of the rectangular slot, and the upper and lower ends of the rear surface of the top plate are respectively fixedly connected to the front end of the spring 2 adjacent to the same side; the unlocking component also includes a frame-type sliding plate slidably connected to the rectangular slot, an inclined plate is arranged at the lower end between the left and right walls of the frame-type sliding plate, and the inclined plate is matched with the inclined surface arranged at the rear end of the top plate; the unlocking component also includes a spring 3 arranged between the bottom wall of the rectangular slot and the lower surface of the frame-type sliding plate; the unlocking component also includes a button arranged on the upper surface of the frame-type sliding plate.

[0008] The upper surface of the bolt is provided with a recessed groove matched with the button.

[0009] The beneficial effects of the above technical solution of the utility model are as follows:

[0010] 1. First, the user passes the bolts through the holes of the hardware to be connected in sequence, and then screws the nut into the lower end of the bolt. During the operation, adjust the position of the limit collar to ensure that its boss is accurately matched with the rectangular mounting groove. As the nut is gradually tightened, the limit collar and its related structures slide upward along the rectangular mounting groove. In this process, the ratchet plate will continuously push the sliding limit clamp, and the sliding limit clamp will overcome the elastic force of the spring and move into the limiting slide groove for avoidance. When the sliding limit clamp passes through each ratchet tooth of the ratchet plate, it will reset under the action of the rebound force of the spring and embed into the next ratchet groove. This step is repeated. After the bolt is screwed into place, the sliding limit clamp is clamped into the corresponding ratchet groove of the ratchet plate under the action of the elastic force of the spring, achieving the effect of locking when tightening, which can effectively prevent the nut from rotating counterclockwise, and can also achieve self-locking when dealing with hardware connections of different thicknesses, ensuring that the hardware is stable and not loose, and enhancing the reliability of the connection of the hardware connector.

[0011] 2. When unlocking is required, the user presses the button, and the button moves downward, driving the frame-shaped sliding plate and the inclined plate to overcome the elastic force of spring three and slide downward, so that the inclined plate pushes the top plate to overcome the elastic force of spring two and move forward. When the top plate moves forward, its front end pushes the sliding limit clamp through the rectangular through-hole, so that the sliding limit clamp overcomes the elastic force of spring one and separates from the ratchet plate, thereby releasing the self-locking state, and then the nut can be removed, realizing convenient self-locking and unlocking operations, and improving the safety and practicality of hardware connectors.

[0024] The working principle of a hardware connector with a self-locking structure provided by the utility model is as follows: first, the user sequentially passes the bolt 100 through the opening of the hardware to be connected, and then screws the nut 200 into the lower end of the bolt 100. During the operation, the position of the limit collar 302 is adjusted to ensure that its boss is accurately matched with the rectangular mounting groove 300. As the nut 200 is gradually tightened, the limit collar 302 and its related structures slide upward along the rectangular mounting groove 300. During this process, the ratchet plate 301 will continuously push the sliding limit card The cam 303 is pressed against the locking cam 304 and the locking cam 303 is pressed against the locking cam 304.
