Technical Field
[0001] The utility model relates to the technical field of self-locking copper nuts, in particular to an anti-deformation self-locking copper nut. Background Art
[0002] Self-locking nuts are a special type of nut whose main feature is that they can prevent loosening after tightening. This type of nut is usually used in environments with large vibrations or impacts, such as mechanical equipment, aerospace, and automobile manufacturing. The working principle of self-locking nuts mainly relies on friction. Their special design (such as polygonal threads or flange threads) can tightly engage with the metal surface after tightening, increasing friction and preventing loosening under vibration or impact. In addition, self-locking nuts also have many types, such as those with embedded nylon rings, those with neck closures, and those with metal anti-loosening devices. These types are designed to provide a more reliable tightening effect.
[0003] Since the nut is made of metal material, its plasticity is poor. When the nut is impacted by the outside world, it is easy to cause local deformation of the nut. After the surface of the nut is deformed, its internal self-locking structure will be affected, which will cause the nut to loosen when vibrating and detach from the target of the threaded connection. The nut is small in size and is often used in a narrow space. It is not convenient to connect an anti-deformation and anti-collision mechanism to the outside of the nut. Therefore, the nut itself needs to have an anti-deformation function to ensure the normal use of the self-locking structure.
[0004] Therefore, it is urgent to provide an anti-deformation self-locking copper nut to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the general anti-deformation self-locking nut is inconvenient to disassemble and assemble in order to realize the anti-deformation function, and cannot be adjusted when the anti-deformation structure has problems.
[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an anti-deformation self-locking copper nut, including a positioning component, the outer side of the positioning component is rotatably connected with a damping component, and the outer side of the positioning component is provided with a clamping component, and the clamping component limits the damping component;
[0007] Two flipping components are symmetrically arranged inside the shock absorbing component, and a stop component is slidably connected to one side of the shock absorbing component, and the friction force is increased when the stop component contacts the positioning component;
[0008] A guiding component is provided between the positioning component and the shock absorbing component.
[0009] The utility model is further configured as follows: the positioning assembly comprises a body, a clamping ring is arranged on the outer side of the body, and a gasket is embedded in the inner side of the body.
[0010] Through the above technical solution, washer locking is one of the most common self-locking methods of nuts. It adds a washer at the bottom of the nut or at the junction of the nut and the thread, so that the washer is subjected to tensile force, thereby causing the nut to be subjected to a preload force to achieve a self-locking function.
[0011] The utility model is further configured as follows: the shock-absorbing assembly includes a first shell and a second shell, the first shell and the second shell are rotatably connected to the retaining ring respectively, two through holes are opened on one side of the first shell, plug blocks are slidably connected in the through holes, the two plug blocks are respectively inserted into one side of the second shell, a slide plate is slidably connected in the plug blocks, a first spring is arranged between the slide plate and the inside of the plug blocks, two rotating holes are symmetrically opened inside the first shell, two plug holes are symmetrically opened inside the first shell, and a groove is opened on one side of the second shell.
[0012] Through the above technical solution, the first shell and the second shell are spliced together to form an annular structure and are rotatably connected to the outside of the retaining ring. Two plug-ins connect the first shell and the second shell so that the two can rotate together. When the outside of the first shell and the second shell is impacted, the first shell and the second shell will rotate around the retaining ring to unload the force, and the protector body will not be deformed, so that the gasket can work normally for self-locking, and the slide plate can be retracted into the first shell. When in use, the first spring will pop it out of the first shell.
[0013] The utility model is further configured as follows: the locking assembly includes a swivel, the swivel is threadedly connected to the device body, a baffle is provided below the swivel, the baffle is sleeved with the device body, an insert ring is provided at the bottom of the swivel, and a slot is opened inside the baffle.
[0014] Through the above technical solution, the first shell and the second shell can be easily installed after the swivel and the baffle are disassembled, and the baffle can limit the first shell and the second shell.
[0015] The utility model is further configured as follows: the flip assembly comprises a rotating plate, the rotating plate is rotatably connected to the rotating hole, an inserting plate is slidably connected inside the rotating plate, and the inserting plate is adapted to the inserting hole.
[0016] Through the above technical solution, when the plug block is plugged into the second shell, in order to prevent the slide plate from popping out, the rotating plate can be made parallel to the top of the first shell and the plug plate and the socket can be plugged in to limit the position of the slide plate. When the plug block is not plugged into the second shell, the first shell is not fully installed. At this time, the rotating plate is rotated to a position perpendicular to the top of the first shell and the plug plate is slid between the plug block and the inner wall of the first shell. The plug block can be limited so that the plug block will not extend out when it is not spliced to prevent unnecessary wear.
[0017] The utility model is further configured as follows: the stop assembly includes a protection plate, the protection plate is slidably connected to the second shell, two second springs are symmetrically provided on one side of the protection plate, the stop assembly includes a rotating shaft, the rotating shaft is rotatably connected to the groove, and a partition is provided on one side of the rotating shaft.
[0018] Through the above technical solution, the inner wall of the protective plate is very rough, and the sliding protective plate fits with the retaining ring to increase the friction. When the rotating shaft is rotated to allow the partition to rotate to fit with the protective plate, the protective plate can continue to fit with the retaining ring, making the first shell and the second shell unable to rotate, and the whole can be restored to a normal nut, which prevents the first shell and the second shell from rotating during installation to cause inconvenience, and can also increase stability without the need for anti-deformation.
[0019] The utility model is further configured as follows: the guiding assembly comprises a fixed plate and a plurality of movable plates, the fixed plate is embedded in the bottom of the baffle, and the plurality of movable plates are respectively embedded in the top of the first shell and the second shell.
[0020] Through the above technical solution, when any moving plate is aligned with the fixed plate, the first shell, the second shell, the device body and the baffle are aligned, preventing the first shell and the second shell from protruding when the protective plate and the snap ring are fitted, thereby reducing the occurrence of wear.
[0021] The beneficial effects of the utility model are as follows:
[0022] 1. The utility model splices the first shell and the second shell into an annular structure, and protects the outer side of the clamp ring. When a foreign object impacts the first shell and the second shell, the first shell and the second shell will rotate around the clamp ring to unload the force, and has an anti-deformation function. Even if the first shell and the second shell are deformed under the impact, they can be disassembled for maintenance or replacement, so that the body can always be self-locking, with a long service life and high stability;
[0023] 2. The utility model can increase the friction of the contact surface through the contact between the protection plate and the retaining ring, so that the first shell and the second shell cannot rotate. Adjustment can be made under specified circumstances, and the overall structure can be adjusted to be unable to rotate like an ordinary nut, which is convenient for adjustment according to different usage environments.
