DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figure 1-4 The utility model provides a technical solution: an adjusting nut anti-loosening device, comprising a connecting disk 1, a screw rod 2 is connected to the top of the connecting disk 1, a nut 3 is threadedly connected to the outer ring of the screw rod 2, a receiving groove 5 is opened on the top of the connecting disk 1, a fixing ring 16 is arranged at one end of the receiving groove 5, a first connecting ring 6 is movably arranged in the inner cavity of the fixing ring 16, a plurality of first latch teeth 8 are distributed in an annular shape on the top of the first connecting ring 6, a second connecting ring 9 is connected to the bottom of the nut 3, a plurality of second latch teeth 10 are distributed in an annular shape on the bottom of the second connecting ring 9.

[0022] One side of the first latching tooth 8 and the second latching tooth 10 are both arc-shaped.

[0023] A plurality of compression springs 15 are distributed in a ring shape at the bottom of the first connecting ring 6 .

[0024] In this embodiment, Figure 1 As shown, when the nut 3 is connected to the screw rod 2, one side of the plane of the first latch tooth 8 and the second latch tooth 10 fits with each other; in actual use, the nut 3 is rotated clockwise, and the nut 3 is continuously moved down on the outer ring of the screw rod 2 through the thread until the first latch tooth 8 comes into contact with the second latch tooth 10. At this time, the arc surface of the second latch tooth 10 fits with the arc surface of the first latch tooth 8, and pushes the first latch tooth 8 downward during the downward movement of the nut 3. At this time, the first latch tooth 8 compresses the compression spring 15 through the first connecting ring 6, and then when the first latch tooth 10 is no longer in contact with the second latch tooth 8, The compression spring 15 loses pressure and pushes the first clamping block 8 upward until the first clamping tooth 8 and the second clamping tooth 10 are engaged. At this time, the first clamping tooth 8 will restrain the second clamping tooth 10 to achieve the purpose of preventing loosening; that is, affected by the arc surface of the first clamping tooth 8 and the second clamping tooth 10, the first clamping tooth 8 allows the second clamping tooth 10 to rotate clockwise, and affected by the plane of the first clamping tooth 8 and the second clamping tooth 10, the first clamping tooth 8 refuses the second clamping tooth 10 to rotate counterclockwise to prevent the nut 3 from loosening, thereby improving the anti-loosening effect of the device. The overall structure of the device is simple, practical, and suitable for popularization and use.

[0025] Among them, the inner cavity of the connecting disk 1 is provided with multiple limit grooves 17, the bottom of the connecting disk 1 is provided with a groove 14, the inner cavity of the limit groove 17 is movably provided with a limit rod 18, the inner cavity of the groove 14 is movably provided with an adjustment block 11, the top of the adjustment block 11 is provided with a threaded connection groove 13, the limit rod 18 is movably connected to the threaded connection groove 13, the outer circle of the adjustment block 11 is distributed with a plurality of anti-slip grooves 12, the top of the limit rod 18 is fixedly connected to the bottom of the first connecting ring 6, and the outer circle of the first connecting ring 6 is connected to the limit ring 7.

[0026] In this embodiment, Figure 4 As shown, there are four limit rods 18 arranged in a ring shape, which can play a limiting role and prevent the first connecting ring 6 from rotating, thereby improving the stability of the device; the adjusting block 11 is used to limit the bottom end of the limit rod 18, and the connection length between the adjusting block 11 and the limit rod 18 can be adjusted through the threaded connection groove 13, thereby adjusting the extension length of the first clamping tooth 8 from the storage groove 5, so that the staff can adjust the distance between the nut 3 and the connecting disk 1 according to actual needs, further improving the practicality of the device; when the nut 3 needs to be removed, the staff can pull down the limit rod 18 through the adjusting block 11, and at this time the limit rod 18 can pull down the first connecting ring 6 until the first clamping tooth 8 is disconnected from the second clamping tooth 10, and the overall operation is simple and convenient to use.

[0027] Wherein, a sealing sleeve 4 is provided on the outer ring movable sleeve at the bottom end of the connecting disk 1 .

[0028] In this embodiment, the sealing sleeve 4 is made of rubber. After the nut 3 and the screw rod 2 are connected, the sealing sleeve 4 is sleeved on the bottom end of the connecting plate 1. At this time, the sealing sleeve 4 can seal the groove 14 to prevent dust, rainwater and other substances from entering the device through the groove 14, causing a situation that is difficult to occur.
