In the figure: the anti-skid device comprises a first nut 1, a second nut 2, a sliding rod 3, a sliding sleeve 4, a pull rod 5, a spring 6, a limiting block 7, a wear-resistant pad 8, a rubber gasket 9 and an anti-skid bump 10.

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. 1-2, a novel anti-loose nut comprises a first nut 1 and a second nut 2, wherein internal threads of the first nut 1 and the second nut 2 are reversely arranged to prevent the first nut 1 and the second nut 2 from synchronously rotating, a rubber gasket 9 is fixedly connected to the bottom of the second nut 2, and a plurality of anti-skid lugs 10 are arranged on the outer wall of the second nut 2 to facilitate the rotation of the second nut 2;

in this embodiment, a plurality of sliding grooves are formed in the outer wall of the first nut 1 in a surrounding manner, a sliding rod 3 is fixedly connected in each sliding groove and used for supporting a sliding sleeve 4, the sliding sleeve 4 is slidably sleeved at the bottom of the sliding rod 3 and used for fixing the second nut 2 and the first nut 1, a plurality of wear pads 8 are fixedly connected to the bottom of the first nut 1, friction force between the first nut 1 and the second nut 2 is enhanced, and through holes corresponding to the sliding sleeves 4 are formed in the wear pads 8;

in the embodiment, the sliding rod 3 is sleeved with the spring 6 in a sliding manner, two ends of the spring 6 are respectively and fixedly connected with the sliding sleeve 4 and the inner wall of the sliding groove, a certain elastic extrusion effect is exerted on the sliding sleeve 4, and one end of the sliding rod 3, which is positioned in the sliding sleeve 4, is fixedly connected with the limiting block 7, so that the sliding rod 3 is prevented from falling off from the sliding sleeve 4;

in this embodiment, fixedly connected with pull rod 5 on the outer wall of sliding sleeve 4 conveniently stimulates sliding sleeve 4, and the bottom of sliding sleeve 4 runs through the interior bottom and the downwardly extending of spout, and the top of second nut 2 is encircleed and is equipped with a plurality of slots that correspond with sliding sleeve 4.

In this embodiment, through after selecting the screw rod with second nut 2, then with 1 screw in screw rod of first nut, then insert the slot on the second nut 2 with sliding sleeve 4 in, spring 6 can play certain elasticity extrusion effect to sliding sleeve 4 simultaneously, because the reverse setting of first nut 1 and 2 inside screw threads of second nut, can effectively prevent not hard up of first nut 1 and second nut 2 simultaneously.

In this embodiment, stopper 7 can prevent that slide bar 3 from droing from sliding sleeve 4, and pull rod 5 can conveniently stimulate sliding sleeve 4, and the frictional force between first nut 1 and the second nut 2 can be strengthened in the setting of wear pad 8 simultaneously, and the setting of while skid proof block 10 can conveniently rotate second nut 2.
