[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Depend on Figure 1 、 Figure 2 and Figure 3The utility model provides an anti-seismic locking nut for a lathe. The top wall of the nut body 100 is provided with a telescopic groove, which is convenient for limiting and guiding the movement of the protective sleeve 101. The inner wall of the telescopic groove is slidably connected with the protective sleeve 101, which is convenient for protecting the part leaking out of the upper end of the bolt. The top wall of the protective sleeve 101 is screwed with a fastening screw 102, which is convenient for driving the pushing piece 103 to move. The bottom end of the fastening screw 102 passes through the bottom wall of the inner cavity of the protective sleeve 101 and is rotatably connected with the pushing piece 103. The pushing piece 103 is convenient for abutting against the bolt, and the bottom wall of the protective sleeve 101 is fixedly connected with a limiting ring 104, which is convenient for sliding on the inner wall of the telescopic groove through the limiting ring 104. The telescopic groove facilitates the movement of the limiting ring 104, and the limiting ring 104 is located on the inner wall of the telescopic groove.

[0021] In this embodiment: the nut body 100 is twisted by a tool so that the nut body 100 is connected to the bolt for easy tightening and installation on a lathe. The protective sleeve 101 can be raised and lowered during twisting, which is convenient for protecting the protruding bolt. The fastening screw 102 is rotated to make it move on the top wall of the protective sleeve 101. The fastening screw 102 is used to drive the pushing piece 103 to move. The pushing piece 103 moves to push the bolt, so that the protective sleeve 101 drives the limiting ring 104 to move, and the limiting ring 104 is limited by the telescopic groove, thereby applying a force in the opposite direction to the nut body 100, which can effectively prevent the nut from loosening, and can make the device convenient for protecting the exposed part of the bolt to avoid corrosion of the bolt, which is beneficial to the installation and tightening of the nut body 100.

[0022] A groove is provided on the bottom wall of the nut body 100, and a fastening ring 105 is slidably connected to the inner wall of the groove. The fastening ring 105 facilitates mechanical pushing of the anti-slip pad 106, and the bottom wall of the fastening ring 105 is fixedly connected to the anti-slip pad 106, which facilitates anti-slipping and avoids deflection.

[0023] In this embodiment: the nut body 100 is screwed for tightening and installation, the nut body 100 drives the fastening ring 105 to move, and the fastening ring 105 drives the anti-slip pad 106 to move, so that the anti-slip pad 106 fits the surface of the component for limiting. When tightening, the fastening ring 105 is moved in the inner cavity of the groove to squeeze the gas in the inner cavity of the groove. The fastening ring 105 is pushed to move by the air pressure, and the anti-slip pad 106 is driven by the movement of the fastening ring 105, so that the anti-slip pad 106 fits on the component for limiting. This can make it easy for the device to fasten the component and make the anti-slip pad 106 fit on the component for limiting, so as to avoid the deflection of the nut body 100 due to vibration and cause loosening.

[0024] The inner wall of the groove is polygonal, and the outer wall of the fastening ring 105 matches the inner wall of the groove. The inner and outer walls of the fastening ring 105 are fixedly connected with a sealing ring 107, which facilitates sealing the joint. The sealing ring 107 is located on the inner wall of the groove.

[0025] In this embodiment: by providing a sealing ring 107, it is convenient to seal the gap between the inner and outer walls of the fastening ring 105, avoiding gas leakage, so that the air pressure can push the fastening ring 105, and the device can facilitate the sealing of the gap between the inner and outer walls of the fastening ring 105, avoiding gas leakage affecting the pushing of the fastening ring 105, which is conducive to fastening and locking.

[0026] The bottom wall of the nut body 100 is fixedly connected with a waterproof ring 108, and the waterproof ring 108 is convenient for fitting the model and sealing on the component. The waterproof ring 108 is made of rubber material.

[0027] In this embodiment, the waterproof ring 108 is used to seal the bottom wall of the nut body 100, thereby preventing water from entering the thread of the bolt from the bottom wall of the nut body 100 and preventing corrosion.

[0028] The left and right side walls of the telescopic slot are both provided with sliding grooves, and the left and right side walls of the limit ring 104 are fixedly connected to the limit blocks 109. The limit blocks 109 facilitate the limiting and guiding of the movement of the limit ring 104. The limit blocks 109 are located in the inner cavity of the sliding groove.

[0029] In this embodiment, the sliding groove facilitates the movement of the limit block 109 to limit and guide the movement of the limit ring 104, and the limit block 109 facilitates the movement of the limit ring 104 to limit and guide the movement, thereby avoiding the deflection of the limit ring 104 and facilitating the lifting and lowering of the protective cover 101.
