Description
Technical field
This utility model relates to check bolt, a kind of check bolt increasing nylon plastic(s) loose-proof sleeve between plain bolt and nut.
Background technology
Existing nylon stop nut, can effectively realize the locking of bolt.Also have on bolt, scribble anaerobic adhesive, locking effect can be played equally.But, common bolts and nuts are not through gluing or increase nylon parts, spring washer can only be relied on to realize locking, and anti-loosing effect is relatively limited.
Summary of the invention
The purpose of this utility model is to provide plastic sheath check bolt, by between plain bolt and nut, increases the nylon sleeve of a hollow, plays the effect of increasing friction force, reach locking purpose.Nut is threaded onto the position of plastics loose-proof sleeve by the screw rod on bolt, continues turn-knob until the whole outside being wrapped in plastics loose-proof sleeve of nut.The crimp between bolts and nuts of plastics loose-proof sleeve, and produce powerful frictional force, it is achieved locking effect.
For achieving the above object, this utility model provides following technical scheme: plastic sheath check bolt, it is made up of bolt, nut, plastics loose-proof sleeve, packing ring, packing ring, plastics loose-proof sleeve are enclosed within the screw rod of bolt, after the fastening of bolts and nuts turn-knob, plastics loose-proof sleeve is clipped between the two connection, junction；Plastics loose-proof sleeve is a hollow nylon pipe, and its diameter is more than nut internal diameter, and internal diameter is more than the diameter of screw rod on bolt, and plastics loose-proof sleeve sidewall has certain thickness, upper/lower terminal exit, and at least one end side is trapezoidal annular ring hypotenuse.
Further, plastics loose-proof sleeve is provided with screw thread.
Further, plastics loose-proof sleeve can save the design of exit, two ends annular ring hypotenuse.
Further, the wall thickness of plastics loose-proof sleeve strengthens with Bolt sizes and thickens, and concrete size carries out the setting of correspondence according to the diameter of screw rod.
Further, as required, screw rod increases spring washer.
Good result of the present utility model is: allow common bolts and nuts reach locking effect after connecting by increasing plastics loose-proof sleeve.Have an advantage in that and need not bolt or nut exclusively carry out the processing such as gluing.Plastics loose-proof sleeve is placed on the screw rod of bolt, can be achieved with locking effect, and effect is suitable with the anti-loosing effect of existing gluing bolt and nylon stop nut after being normally connected with nut.It can be as the succedaneum of spring washer, it is possible to be used in combination.Plastics loose-proof sleeve can also be supplied to market separately as a parts product.And production cost is low, simple in construction, anti-loosing effect is good, has market prospect widely.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.
As shown in figures 1-8, plastic sheath check bolt, forms including by bolt 1, nut 2, plastics loose-proof sleeve 3, packing ring 4, and packing ring 4, plastics loose-proof sleeve 3 are enclosed within the screw rod 11 of bolt 1, after bolt 1 fastens with nut 2 turn-knob, plastics loose-proof sleeve 3 is clipped between the two connection, junction；Plastics loose-proof sleeve 3 is a hollow nylon pipe, its diameter is more than nut 2 internal diameter, internal diameter is more than the diameter of screw rod 11 on bolt 1, highly it is equal to, more than nut 2 height, plastics loose-proof sleeve 3 sidewall has certain thickness, upper/lower terminal exit, at least one end side is trapezoidal, outward-dipping annular ring hypotenuse 31；Plastics loose-proof sleeve 3 is nylon material.
Concrete, the screw rod 11 of bolt 1, through connected thing, is inserted in packing ring 4 at the other end, then is inserted in plastics loose-proof sleeve 3, and nut 2 is connected on screw rod 11 by the way of turn-knob.When being threaded onto plastics loose-proof sleeve 3, the female thread of nut 2 is by bigger torsion extruding plastics loose-proof sleeve 3, and continues downward turn-knob, fits until bolt 1 is connected with nut 2.Annular ring hypotenuse on plastics loose-proof sleeve 3 31 is conducive to the female thread turn-knob smoothly of nut 2 to plastics loose-proof sleeve 3.Between bolt 1 and nut 2 after tightening, clip the plastics loose-proof sleeve 3 being deformed.The plastics loose-proof sleeve 3 being deformed is when nut 2 stops after twisting, and its counteracting force and frictional force can realize the effect of a fastening to bolt 1 and nut 2, thus reach locking purpose.
Nut 2 internal diameter refers to that the distance between nut 2 female thread, screw rod 11 diameter comprise externally threaded diameter length.Plastics loose-proof sleeve 3 is provided with screw thread, more effectively downwards, the realization of anti-loosing effect can be also beneficial to by guiding nut 2 turn-knob.On some bolts 1 being relatively small in size, use plastics loose-proof sleeve 3, the structure of annular ring hypotenuse 31 can be saved.Certainly, termination can also be fabricated to semicircular ring, and purpose is all that effective guiding nut 2 turn-knob smoothly enters on plastics loose-proof sleeve 3.Rows of loop hypotenuse is in the case of plastics loose-proof sleeve 3 thickness is relatively thick, and exit the most at one end is configured.It is respectively provided with on both sides, meeting enhanced convenience during use, but premise is not affect to be connected between nut 2 with plastics loose-proof sleeve 3, and ensure that contact surface reaches the area of effective anti-loosing effect.
The plastics or other materials that use need have anti-skidding, wear-resisting characteristic, its situation about can loosen between effectively preventing bolt 1 and nut 2.Wear-resisting characteristic beneficially nut 2 can repeatedly tighten and take off, moreover it is possible to keep a good anti-loosing effect.The plastics loose-proof sleeve 3 made for rubber, anaerobic adhesive, quoit, canvas etc., also can play locking effect.But, the effect of nylon is the most better.Plastics loose-proof sleeve 3 is the difference according to bolt 1 size and carries out different setting, namely its size having multiple model and size.Bolt 1 is the biggest, and plastics loose-proof sleeve 3 size is the biggest, and the wall thickness of sidewall is the thickest.Packing ring 4 increases spring washer, does not interferes with the use of plastics loose-proof sleeve 3.And plastics loose-proof sleeve 3 is the substituting product of one of spring washer, the effect played is identical with spring washer.Plastics loose-proof sleeve 3 can be supplied to market separately as a product, provides a locking accessory simple, effective for common bolt 1.
