Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 3, the present invention provides a technical solution: including the threaded rod 1 that runs through equipment and installed object, its characterized in that: the surface of a threaded rod 1 is provided with left-handed thread teeth 2, the surface of the left-handed thread teeth 2 is movably connected with a first threaded cap 3, the inside of the first threaded cap 3 is provided with a mounting groove 4, the inside of the mounting groove 4 is provided with clamping pieces 5, one end of the threaded rod 1 is fixedly connected with a thin screw rod 6, the surface of the thin screw rod 6 is provided with right-handed thread teeth 7, the other end of the threaded rod 1 is fixedly connected with an end cap 8, the surface of the first threaded cap 3 is in threaded connection with a second threaded cap 9, the surface of the threaded rod 1 is sleeved with a gasket 10, the upper surface of the gasket 10 is provided with left-handed anti-reversion teeth 11, the lower surface of the first threaded cap 3 is provided with right-handed anti-reversion teeth 12, the upper surface of the end cap 8 is provided with a circular groove 13, the inside of the circular groove 13 is provided with a spring 14, one end of the spring 14 is provided with a small steel column 15, through the arrangement of a multiple anti-loosening structure, the clamping pieces can be installed after the equipment, the threaded rod at the center thereof is clamped to keep the position of the first threaded cap fixed, while the second threaded cap is arranged to be connected with the threaded rod and the first threaded cap through a thread tooth with different rotation directions, even if the first screw cap is loosened under the action of vibration or impact force, the first screw cap can not be retracted due to the action of the second screw cap, thereby playing the role of anti-loosening, and the gasket is also provided with anti-reverse teeth for preventing back-off, therefore, even if the thread teeth are worn, the anti-loosening function can be achieved to a certain extent, the reliability of the device in use is increased, therefore, the device can keep the equipment fixed in a more complex environment, the application range is increased, the detailed description of the known functions and the known components is omitted in the specific embodiment of the disclosure, and the adopted operation means are consistent with the parameters of the instruments on the market in order to ensure the compatibility of the equipment.
