Abstract

The utility model discloses a kind of bolt easy to clean, its drip irrigation device comprises bolt head, screw rod, screw rod and bolt head are wholely set, bolt head is provided with fixed groove, fixed groove bottom-hinged has turnover panel, turnover panel can with fixed groove bottom fit, turnover panel is fitted in bottom fixed groove, be hedged off from the outer world by the part that turnover panel is fitted bottom fixed groove, when foreign material descend slowly and lightly to fixed groove, can only drop on turnover panel, thus avoid external impurities and fall bottom fixed groove, turnover panel overturns along hinged place by people, thus turnover panel is flipped to one side, thus the foreign material sticked on turnover panel are routed up by turnover panel, foreign material are effectively made to clear up away rapidly, make people spanner can easily be put into fixed groove to rotate, turnover panel can be turned back after screws and continue to use, be convenient for people to use bolt, and turnover panel materials are less, structure is simple, effectively decrease the cost of generation.

Description

Bolt easy to clean

Technical field

The utility model relates to a kind of bolt easy to clean.

Background technique

Bolt is by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, and coordinate with the tapped hole on part and be fixedly connected with part, this Connecting format claims bolt to connect.As bolt is screwed off from tapped hole, can make again part separately, therefore bolt connection belongs to removably connect.

When bolt uses in the presence of a harsh environment, fixed groove on bolt head is easily adhered to blocking by foreign material to be caused spanner cannot insert fixed groove causing bolt not back-out, people need to take sharper object foreign material to be picked out bolt of just back-outing, and make bolt trouble very of back-outing.

And somebody overlaps a protective cover again to protect bolt head after bolt is fixing; but relatively add the thickness of bolt head after loading onto protective cover; cause protective cover can be convex in part surface; and protective cover is easily lost after taking out; inconvenience uses next time, and protective cover covers whole bolt causes manufacturing protective cover and substantially increase the materials cost of single bolt.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide one to facilitate foreign material to take out, and the bolt easy to clean that structure simply, is not easily lost.

For achieving the above object, the utility model provides following technological scheme: a kind of bolt, comprises bolt head, screw rod, described screw rod and bolt head are wholely set, described bolt head is provided with fixed groove, and described fixed groove bottom-hinged has turnover panel, described turnover panel can with fixed groove bottom fit.

Preferably, described turnover panel one end is hinged with pulling-on piece.

Preferably, described pulling-on piece is provided with catching groove, and described bolt head is provided with the discount matched with catching groove.

Preferably, described turnover panel shape matches with fixed groove bottom shape.

Preferably, described turnover panel is made up of plastic materials.

Compared with prior art, the beneficial effects of the utility model are: when bolt does not use or when being bolted on tapped hole, turnover panel is fitted in bottom fixed groove, make to be hedged off from the outer world by the part that turnover panel is fitted bottom fixed groove, when external impurities descends slowly and lightly to fixed groove, can only drop on turnover panel, thus avoid external impurities and fall bottom fixed groove, when people need to carry out rotating bolt by spanner, as long as turnover panel is overturn along hinged place, thus turnover panel is flipped to one side, thus the foreign material sticked on turnover panel are routed up by turnover panel, foreign material are effectively made to clear up away rapidly, make people spanner can easily be put into fixed groove and carry out rotating bolt, turnover panel can be turned back after screws and continue to use, due to turnover panel and fixed groove bottom-hinged, effectively avoid turnover panel to lose, and when turnover panel there is no foreign material, when turnover panel is fitted in bottom fixed groove, spanner also can insert fixed groove, when not having foreign material, turnover panel also can not produce larger impact to rotating bolt, be convenient for people to use bolt, and turnover panel materials are less, structure is simple, effectively decrease the cost of generation.

Embodiment

Referring to figs. 1 through Fig. 3, the screw embodiment that the utility model is easy to clean is described further.

A kind of bolt easy to clean, comprise bolt head 1, screw rod 2, described screw rod 2 is wholely set with bolt head 1, described bolt head 1 is provided with fixed groove 11, described fixed groove 11 bottom-hinged has turnover panel 3, described turnover panel 3 can with fixed groove 11 bottom fit, when bolt does not use or when being bolted on tapped hole, turnover panel 3 is fitted in bottom fixed groove 11, make to be hedged off from the outer world by the part that turnover panel 3 is fitted bottom fixed groove 11, when external impurities descends slowly and lightly to fixed groove 11, can only drop on turnover panel 3, thus avoid external impurities and fall bottom fixed groove 11, when people need to carry out rotating bolt by spanner, as long as turnover panel 3 is overturn along hinged place, thus turnover panel 3 is flipped to one side, thus the foreign material sticked on turnover panel 3 are routed up by turnover panel 3, foreign material are effectively made to clear up away rapidly, make people spanner can easily be put into fixed groove 11 and carry out rotating bolt, turnover panel 3 can be turned back after screws and continue to use, due to turnover panel 3 and fixed groove 11 bottom-hinged, effectively avoid turnover panel 3 to lose, and when turnover panel 3 there is no foreign material, when turnover panel 3 is fitted in bottom fixed groove 11, spanner also can insert fixed groove 11, when not having foreign material, turnover panel 3 also can not produce larger impact to rotating bolt, be convenient for people to use bolt, and turnover panel 3 materials are less, structure is simple, effectively decrease the cost of generation.

Turnover panel 3 one end is hinged with pulling-on piece 4, when people need to rotate turnover panel 3, just turnover panel 3 can be mentioned on pulling-on piece 4 as long as will pull, pulling-on piece 4 improves the area of contact with people's hand, effectively prevent, turnover panel 3 is less and produces when pulling and slide with people's hand comes in contact area, and due to pulling-on piece 4 and turnover panel 3 hinged, when people's pull-up turnover panel 3, hand does not need to rotate, more comfortable when people are used.

Pulling-on piece 4 is provided with catching groove 5, described bolt head 1 is provided with the discount 51 matched with catching groove 5, when bolt does not use or when being bolted on tapped hole, turnover panel 3 is fitted in bottom fixed groove 11, pulling-on piece 4 is fixed with bolt head 1 with coordinating of discount 51 by catching groove 5, thus time turnover panel 3 can be fixed on bottom fixed groove 11, the generation that effectively prevents turnover panel 3 random upset.

Turnover panel 3 shape matches with fixed groove 11 bottom shape, turnover panel 3 can just all be covered bottom fixed groove 11 completely, effectively avoid foreign material to drop on bottom fixed groove 11, cleaning effect after turnover panel 3 is routed up improves, turnover panel 3 is made up of plastic materials, plastic materials cost is low, and can not get rusty.
