[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1 to 6 As shown, a typical embodiment of this utility model provides a novel screw with an anti-loosening clip, including a bolt 1, a nut 2 and an anti-loosening component 3; the nut 2 is threadedly connected to the bolt 1, the anti-loosening component 3 is disposed on the bolt 1, the anti-loosening component 3 can contact the side of the nut 2 away from the tail of the bolt 1, and the anti-loosening component 3 can limit the movement distance of the nut 2 on the bolt 1.
[0021] In use, bolt 1 is passed through the hole to be fixed and installed, and then nut 2 is threaded to bolt 1 so that the tail of bolt 1 and nut 2 are in contact with the two sides of the hole, thus completing the installation of bolt 1 and nut 2. By adjusting the anti-loosening component 3, the anti-loosening component 3 can contact the side of nut 2 away from the tail of bolt 1, so that nut 2 cannot move towards the head of bolt 1, thus achieving the effect of preventing nut 2 from loosening.
[0022] The bolt 1 has a slot 1-1. The anti-loosening component 3 includes a moving rod 3-1, a stop block 3-2 and a rack 3-3. The moving stop block 3-2 is rotatably mounted on the end of the moving rod 3-1. The rack 3-3 is slidably mounted on the moving rod 3-1. The moving rod 3-1 is slidably mounted inside the slot 1-1 and passes through the tail of the bolt 1. The stop block 3-2 can contact the side of the nut 2 away from the tail of the bolt 1.
[0023] When adjusting the anti-loosening component 3, by moving the rack 3-3, the moving rod 3-1 and the stop block 3-2 are driven to move towards the tail of the bolt 1 inside the strip groove 1-1. When the stop block 3-2 contacts the side of the nut 2 away from the tail of the bolt 1, the nut 2 cannot move towards the head of the bolt 1, thus achieving the effect of preventing the nut 2 from loosening.
[0024] The moving rod 3-1 is rotationally connected with one side of the bottom end of the block 3-2, the block 3-2 can be switched between horizontal to the moving rod 3-1 and vertical to the moving rod 3-1, when the block 3-2 is horizontal to the moving rod 3-1, the bottom surface of the block 3-2 is in contact with the outer surface of the head of the bolt 1, when the block 3-2 is vertical to the moving rod 3-1, the bottom surface of the block 3-2 is in contact with the bottom surface of the strip-shaped groove 1-1.
[0025] When the block 3-2 is horizontal to the moving rod 3-1, the bottom surface of the block 3-2 is in contact with the end surface of the bolt 1, which facilitates the block 3-2 to remain stable, at this time, the block 3-2 is located within the diameter range of the bolt 1, which facilitates the block 3-2 to be inserted into the hole;
[0026] When the rack 3-3 drives the moving rod 3-1 to move, the bottom surface of the block 3-2 is in contact with the end of the strip-shaped groove 1-1, the rack 3-3 is continuously pulled, so that the block 3-2 can be blocked by the end of the strip-shaped groove 1-1, so that the block 3-2 can be flipped, so that the block 3-2 is switched from the state of being horizontal to the moving rod 3-1 to the state of being vertical to the moving rod 3-1;
[0027] When the block 3-2 is vertical to the moving rod 3-1, the bottom surface of the block 3-2 is in contact with the bottom surface of the strip-shaped groove 1-1, so that the block 3-2 can remain in the vertical state, which facilitates the block 3-2 to be in contact with the nut 2, when the rack 3-3 moves, the block 3-2 is tightly attached to the nut 2, which facilitates the block 3-2 to lock the nut 2, so as to achieve the effect of preventing the nut 2 from being detached.
[0028] The tail of the bolt 1 is rotationally installed with a rotating head 1-3, the rotating head 1-3 is internally provided with a thread, the thread on the rotating head 1-3 is oppositely arranged with the thread of the bolt 1, the teeth of the rack 3-3 can be threadedly connected with the thread of the rotating head 1-3.
[0029] After the nut 2 and the bolt 1 are threadedly connected, the rotating head 1-3 is rotated, so that the thread of the rotating head 1-3 is rotated, since the teeth are threadedly connected with the thread of the rotating head 1-3, when the rotating head 1-3 is rotated, the rack 3-3 can be driven to move, so that the block 3-2 can be tightly in contact with the nut 2;
[0030] After the installation is completed, since the thread of the rotating head 1-3 is oppositely arranged with the thread of the bolt 1, the nut 2 is locked on the bolt 1.
[0031] The bottom surface of the strip-shaped groove 1-1 is provided with a sliding groove 1-2, the inside of the moving rod 3-1 is slidingly installed with a top rod 3-4, the top surface of the top rod 3-4 is in contact with the bottom surface of the rack 3-3, the bottom surface of the top rod 3-4 penetrates through the bottom surface of the moving rod 3-1 and extends downward, and the bottom surface of the top rod 3-4 is slidingly installed in the sliding groove 1-2.
[0032] When the jacking rod 3-4 rises, it can slide inside the sliding groove 1-2 and push the rack 3-3 to move upwards, so that the rack 3-3 can be screwed with the threads of the rotating head 1-3, and when the rotating head 1-3 is rotated, the rack 3-3 can be driven to move towards the nut 2;
[0033] When the jacking rod 3-4 descends, the rack 3-3 loses the support of the jacking rod 3-4 and falls downwards, so that the teeth are separated from the threads of the rotating head 1-3, and the rack 3-3 loses the locking force of the rotating head 1-3. At this time, rotating the nut 2 can drive the nut 2 and the one-end rod to move towards the head of the bolt 1, so as to disassemble the nut 2, which has the advantage of not needing to disassemble the moving rod 3-1 first and then disassemble the nut 2.
[0034] The tail of the thread is provided with a rotating rod 4, the end of the rotating rod 4 penetrates the tail of the thread, and a rotating lever 4-1 is fixedly installed. The two ends of the rotating rod 4 are fixedly installed with a rotating ring 5, the rotating ring 5 is rotatably installed at the tail of the bolt 1, the bottom surface of the jacking rod 3-4 is in contact with the outer wall of the rotating ring 5, the two ends of the rotating ring 5 are provided with inclined surfaces 5-1, and the outer surface of the rotating ring 5 is provided with a groove 5-2. The bottom surface of the jacking rod 3-4 can be inserted into the groove 5-2.
[0035] When the jacking rod 3-4 needs to descend, the rotating lever 4-1 is rotated to drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it can drive the rotating ring 5 to move, so that the bottom surface of the jacking rod 3-4 can be separated from the groove 5-2. When the bottom surface of the jacking rod 3-4 is in contact with the outer surface of the rotating ring 5, the teeth move to the highest point, so that the teeth are closely combined with the rotating head 1-3. When the bottom surface of the jacking rod 3-4 is in contact with the groove 5-2, the teeth have a certain gap with the rotating head 1-3, which is convenient for the rotating head 1-3 to rotate. When the bottom surface of the jacking rod 3-4 moves to the opening of the rotating ring 5, the jacking rod 3-4 moves downwards.
[0036] When the jacking rod 3-4 needs to rise, the rotating lever 4-1 is rotated to drive the rotating rod 4 to rotate. When the rotating ring 5 rotates, it can be extruded by the inclined surface 5-1, so that the bottom surface of the jacking rod 3-4 can be extruded upwards by the inclined surface 5-1 and drive the teeth to move upwards, so that the teeth can be in contact with the rotating head 1-3.
[0037] When the jacking rod 3-4 is located in the groove 5-2 or the opening of the rotating ring 5, the jacking rod 3-4 can lock the rotating ring 5, so that the rotating ring 5 cannot be easily rotated, and the rack 3-3 can be locked in the state of being in contact with the rotating head 1-3 or being separated from the rotating head 1-3.
[0038] The technical scope of the utility model is not only limited to the content in the above description, and the person skilled in the art can make various deformations and modifications to the above implementation manners without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the range of the utility model.
