Abstract

The utility model discloses a kind of ears sealed self-locking nut, comprise anchor locking-nuts with twolug, described anchor locking-nuts with twolug top is closed end, lower end oral area is provided with counterbore, in counterbore, be provided with rubber washer, in anchor locking-nuts with twolug, be provided with internal thread, be provided with closing in cylindrical at internal thread place, anchor locking-nuts with twolug lower end is provided with supporting plate, is provided with two apertures at the two ends of supporting plate.Rubber washer is directly arranged in the counterbore of nut lower end by the utility model, and anti-decylization is provided with on counterbore inwall, thus effectively prevent rubber washer from dropping in counterbore, the supporting plate of nut lower end instead of the packing ring on existing screw plug simultaneously, therefore do not deposit the problem that rubber washer or packing ring when mounted drop, substantially increase installation efficiency.

Description

A kind of ears sealed self-locking nut
Technical field
The utility model relates to a kind of ears sealed self-locking nut, 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 screw plug on drain tap be turned on, the machine oil in fuel tank is bled off, then screw plug is 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 screw plug time harder.Common sequence of operation is first enclosed within screw plug by rubber washer, then on rubber washer, upper gasket is overlapped again, finally again screw plug 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 screw plug 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 ears sealed self-locking nut that rubber washer or packing ring drop when assembling, to overcome prior art deficiency.
The technical solution of the utility model: a kind of ears sealed self-locking nut, comprise anchor locking-nuts with twolug, described anchor locking-nuts with twolug top is closed end, lower end oral area is provided with counterbore, in counterbore, be provided with rubber washer, in anchor locking-nuts with twolug, be provided with internal thread, be provided with closing in cylindrical at internal thread place, anchor locking-nuts with twolug lower end is provided with supporting plate, is provided with two apertures at the two ends of supporting plate.
Counterbore inwall is provided with anti-decylization, effectively prevents rubber washer from dropping in counterbore.
Owing to adopting technique scheme, the utility model has the advantage of: rubber washer is directly arranged in the counterbore of nut lower end by the utility model, and anti-decylization is provided with on counterbore inwall, thus effectively prevent rubber washer from dropping in counterbore, the supporting plate of nut lower end instead of the packing ring on existing screw plug simultaneously, therefore do not deposit the problem that rubber washer or packing ring when mounted drop, 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;
Description of reference numerals: 1-anchor locking-nuts with twolug, 2-rubber washer, 3-closed end, 4-counterbore, 5-internal thread, 6-closing in cylindrical, 7-supporting plate, 8-aperture, the anti-decylization of 9-.
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 the structure of a kind of ears sealed self-locking nut of the present utility model as shown in Figure 1, comprise anchor locking-nuts with twolug 1, described anchor locking-nuts with twolug 1 top is closed end 3, lower end oral area is provided with counterbore 4, rubber washer 2 is provided with in counterbore 4, further, counterbore 4 inwall is provided with anti-decylization 9, thus effectively prevents rubber washer 2 from dropping in counterbore 4.In anchor locking-nuts with twolug 1, be provided with internal thread 5, at internal thread 5, place is provided with closing in cylindrical 6, and anchor locking-nuts with twolug 1 lower end is provided with supporting plate 7, is provided with two apertures 8 at the two ends of supporting plate 7.
