Abstract
The utility model discloses a kind of encapsulate sealing bolt, be enclosed with rubber sleeve (2) at the head of bolt (1), rubber sleeve (2) is provided with the rubber ring (3) in parcel bolt (1) bar portion.Rubber sleeve is closely wrapped in the head of bolt by the utility model, and the rubber ring be provided with on rubber sleeve as seal washer, thus solve rubber washer in prior art and easily drop from bolt, affect the technical problem of installation efficiency, substantially increase installation efficiency.Therefore, the utility model not only structure is simple, easy for installation, quick, and integral sealing effect is better, and can disposablely be in place, and effectively improves installation efficiency.<b/>
Description
Technical field
The utility model relates to a kind of encapsulate sealing bolt, belongs to standard piece manufacturing technology field.
Background technique
In some machinery, convenient in order to change machine oil, usually can drain tap be set, when machine oil changed by needs, the bolt on drain tap and packing ring be turned on, the machine oil in fuel tank is bled off, then bolt and packing ring are screwed on, in fuel tank, add clean machine oil.Often these drain taps are all be located at tank bottoms, and because spatial position is very narrow and small, hand is inconvenient to enter, and not only dismantle very difficult, and screw on bolt and packing ring time harder.Common sequence of operation be first by gasket sleeve on screw plug, and then bolt is screwed on the outside thread of drain tap, owing to being face upward upwards to operate, just easy the rubber washer be enclosed within bolt or packing ring to be got rid of slightly because of carelessness, not only increase operation easier, and waste time and energy.
Model utility content
The purpose of this utility model is, provides that a kind of structure is simple, cost is low, good sealing effect, can avoid the encapsulate sealing bolt that rubber washer or packing ring drop when assembling, to overcome prior art deficiency.
The technical solution of the utility model: a kind of encapsulate sealing bolt, is enclosed with rubber sleeve at the head of bolt, rubber sleeve is provided with the rubber ring of parcel bolt shank.
Described bolt is hexagon head bolt, and its head is cone structure, can not only ensure that rubber sleeve is closely wrapped in bolt head like this, and when bolt can also be prevented to be screwed into, its head skids in rubber sleeve.
The excircle of rubber sleeve is provided with clamp face symmetrically, spanner therefore can be used to be stuck in clamp face by bolt tightening, convenient installation.
Owing to adopting technique scheme, the utility model has the advantage of: rubber sleeve is closely wrapped in the head of bolt by the utility model, and the rubber ring be provided with on rubber sleeve as seal washer, thus solve rubber washer in prior art and easily drop from bolt, affect the technical problem of installation efficiency, substantially increase installation efficiency.Therefore, the utility model not only structure is simple, easy for installation, quick, and integral sealing effect is better, and can disposablely be in place, and effectively improves installation efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Description of reference numerals: 1-bolt, 2-rubber sleeve, 3-rubber ring, 4-clamp face.
Embodiment
In order to make the utility model object, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The structural representation of a kind of encapsulate sealing bolt of the present utility model as shown in Figures 1 and 2, is enclosed with rubber sleeve 2 at the head of bolt 1, and rubber sleeve 2 is provided with the rubber ring 3 in parcel bolt 1 bar portion.
Further, described bolt 1 is hexagon head bolt, and its head is cone structure, can not only ensure that rubber sleeve 2 is closely wrapped in bolt 1 head like this, and when bolt can also be prevented to be screwed into, its head skids in rubber sleeve 2.
Further, the excircle of rubber sleeve 2 is provided with clamp face 4 symmetrically, spanner therefore can be used to be stuck in clamp face by bolt tightening, convenient installation.
