Abstract
The invention discloses a looseness-free screw cap which is the best fastener for a transportation tool and vibrating machinery. The operating principle of the looseness-free screw cap is as follows: when a screw cap 1 is screwed, a ratchet 2 at the upper end of the screw cap 1 is firmly resisted against a ratchet 5 arranged at the top of a screw 4 under the action of a spring 8 (the spring 8 is arranged between the ratchet 2 and the screw cap 1).
Description
One, technical field
The present invention discloses a kind of not loose nut of fastening piece that is applied to means of transportation and vibrations machinery.
Two, technical background
The screw nut of on market, supplying at present all can become flexible because of the reason great majority of vibrations in use for some time, and this just often needs inspection.And concerning means of transportation and vibrations were mechanical, nut is loosening just might cause danger and disaster.There has been not loose everything problem of nut just to be readily solved.
Three, summary of the invention
The object of the invention is providing a kind of not loose nut.Critical piece is made up of ratchet, ratchet, axle, axis hole, spring etc.After nut was screwed, the ratchet (spring is located at the centre of ratchet and nut) that the ratchet that is located at the screw top will be located at the nut upper end pushed up firmly on ratchet in that the following ratchet of the effect of spring is counter, and nut just can not be become flexible.All be provided with spring seat (spring is installed in the spring seat) on nut and the ratchet.
Four, description of drawings
Not loose nut schematic representation
Five, practical implementation method
Now combine accompanying drawing that the structure of loose nut is not further set forth: after nut (1) is screwed; It is firm on ratchet (5) that the ratchet (2) that the ratchet (5) that is located at screw (4) top will be located at nut (1) upper end and pawl base (3) (spring (8) is located at the centre of ratchet (2) and nut (1)) instead push up at the following ratchet of the effect of spring (8) (2), and nut (1) just can not be become flexible.All be provided with spring seat (9) (spring (8) is installed in the spring seat (9)) on nut (1) and the ratchet (2).Be provided with axle (6) in ratchet (2) rear end, be provided with axis hole (7) in axle (6) lower end.
Claims (1)
1. the not loose nut of fastening piece that is applied to means of transportation and vibrations machinery is characterized in that being provided with spring (8) by on nut (1), being provided with ratchet (2) in the centre of ratchet (2) and nut (1), on screw (4), is provided with ratchet (5).
