Abstract
The invention discloses a self-locking and anti-loosening screw rod and a self-locking and anti-loosening nut. Four slope-shaped grooves are formed on the screw rod at equal intervals (one or more slope-shaped grooves can also be formed as required), so that a movable self-locking iron piece on the nut can be locked automatically. When the nut is screwed into the screw rod in a using process, the movable self-locking iron piece on the nut slides into the slope-shaped groove for self-locking every time the nut is screwed into the screw rod for a quarter of a circle. After self-locking, the nut can be prevented from loosening and sliding away. When the nut needs detaching, the movable self-locking iron piece on the nut is reset forcibly and clamped on an unlocking bayonet, so that the nut can be detached normally. The nut can be used again after forced resetting is removed.
Description
Technical field
The present invention relates to a kind of screw rod, nut, can prevent its screw rod, nut loosening and slippage when especially using.
Background technique
At present, various screw rods, nut in use, in the time of especially in being in strenuous vibration, usually can become flexible, even the phenomenon of slippage.Often cause various security incidents thus, even casualties.
Summary of the invention
The problem of the easily loosening and slippage that in use exists at various screw rods, nut, but I have invented the anti-loose screw rod of self-locking, nut.
Description of drawings
Among Fig. 1, the 1st, nut; The 2nd, have the screw rod of four slope shape grooves.
Among Fig. 2, the 1st, nut; The 2nd, have the screw rod of four slope shape grooves.The 3rd, the slope shape groove.
Among Fig. 3, the 1st, nut; The 2nd, but the self-locking iron plate on the nut; The 3rd, the release bayonet socket.
Embodiment
1, on screw rod, equidistantly leave four slope shape grooves (also can leave one or more slope shape groove as required), but for the self-locking activity iron plate self-locking on the nut.
2, but self-locking active iron sheet device is set on nut.But this device is made up of self-locking activity iron plate (but self-locking activity iron plate comprises movable iron plate and spring sheet), release bayonet socket.
During use, when nut precession screw rod, when every precession 1/4th is enclosed, but the self-locking activity iron plate on the nut slips into the self-locking of slope shape groove.Can prevent its loosening and slippage after the nut self-locking.
In the time will unloading lower nut, the self-locking activity iron plate forced resetting with on the nut blocks the self-locking activity iron plate on the nut at the release bayonet socket, just can normally unload lower nut.When reusing, remove forced resetting and get final product.
Claims (4)
1. but the anti-loose screw rod of self-locking, nut is characterized in that equidistantly leaving four slope shape grooves (also can leave one or more slope shape groove as required) on screw rod, but for the self-locking activity iron plate self-locking on the nut.
But 2. the anti-loose screw rod of self-locking according to claim 1, nut, but it is characterized in that on nut, being provided with self-locking active iron sheet device, but this device is made up of self-locking activity iron plate, spring, release bayonet socket.
3. but the anti-loose screw rod of self-locking according to claim 1, nut is characterized in that in use, and when nut precession screw rod, but the self-locking activity iron plate on the nut slips into the self-locking of slope shape groove, can prevent its loosening and slippage after the nut self-locking.
4. but the anti-loose screw rod of self-locking according to claim 1, nut is characterized in that in use, and when nut precession screw rod, but the self-locking activity iron plate on the nut slips into the self-locking of slope shape groove, can prevent its loosening and slippage after the nut self-locking.
