The utility model is equipped with cover for seat on lock body, the position of corresponding keyhole has the through hole that supplies key to insert on this cover for seat; The below of said through hole is provided with hard hat, and an end of this hard hat is articulated in cover for seat, and the other end is a free end, and through hole is opened or closed through the rotation of said hard hat.

Wherein: an end of said hard hat is hinged through cap compression axis and cover for seat; One end of this cap compression axis is connected on the hard hat; The other end passes said cover for seat and is plugged in first groove of offering on the lock body, between the other end of cap compression axis and cover for seat, is provided with the holddown spring that is enclosed within on the cap compression axis; The two ends of said cap compression axis are hemispherical; Form seam between the axis body of the hemispherical at two ends and centre; Wherein the seam of an end is connected to the soffit of hard hat; One end of said holddown spring is connected to the seam of the cap compression axis other end, and the other end of holddown spring is connected on the Stretch slipcovers; Said through hole extends to form seam downwards, the upper surface of hard hat be provided with through hole on corresponding second groove of seam, the seam on the said through hole is contained in second groove; Be provided with the 3rd groove on the said lock body along its length, the inwall that the 3rd groove is relative on cover for seat and the lock body is provided with elastic bumps, and this elastic bumps is placed in said the 3rd groove; Said cover for seat is a cuboid, and inside is and the corresponding square groove of lock body shape, and lock body is contained in this square groove, connects as one through elastic bumps and the 3rd groove and cover for seat.

Advantage of the utility model and good effect are:

1. the utility model is provided with cover for seat and hard hat outside keyhole, has avoided dust, sleet etc. to stop up keyhole.

2. the utility model only needs that hard hat is pulled up rotation and can keyhole be exposed fully, with after rotate hard hat again and reset and get final product, easy to use, simple in structure, cost is low.

3. the hard hat of the utility model is corresponding with the seam on the through hole, and hard hat firm position when closing keyhole play can not take place.

4. be fixed together through groove and convexity between lock body of the utility model and the cover for seat, install firmly, do not come off.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to detail.

As shown in Figure 1, the spring padlock of the utility model is through the mode of exerting pressure cover for seat 2 to be fixed on the lock body 1, and the position of corresponding keyhole 3 has the through hole 4 that supplies key to insert on cover for seat 2; The below of through hole 4 is provided with hard hat 5, and an end of this hard hat 5 is articulated in cover for seat 2, and the other end is a free end, and through hole 4 is opened or closed through the rotation of said hard hat 5.

Like Fig. 6, shown in Figure 7, two relative faces are provided with the 3rd groove 9 along its length on the lock body 1.Cover for seat 2 is a cuboid, and inside is and the corresponding square groove of lock body 1 shape; On cover for seat 2 and the lock body 1 the 3rd groove 9 relative two on be respectively equipped with elastic bumps 10 on the inwall, lock body 1 is contained in this square groove, through cover for seat 2 is exerted pressure, elastic bumps 10 is placed in the 3rd groove 9, and cover for seat 2 and lock body 1 are connected as one, and prevents to come off.

Shown in Fig. 2～5; Through hole 4 on the cover for seat 2 extends to form seam downwards; Hard hat 5 is positioned at the below of through hole 4, and an end is hinged through cap compression axis 6 and cover for seat 2, and the other end is a free end; And the upper surface of hard hat 5 be provided with through hole 4 on corresponding second groove of seam, the seam on the through hole 4 is contained in second groove.The two ends of said cap compression axis 6 are hemispherical, form seam between the axis body of the hemispherical at two ends and centre; One end seam of cap compression axis 6 is connected to the soffit of hard hat 5; The other end is passed, is plugged in first groove of offering on the lock body 18 by cover for seat 2; Between cap compression axis 6 other ends and cover for seat 2, be provided with the holddown spring 7 that is enclosed within on the cap compression axis 6; One end of this holddown spring 7 is connected to the seam of cap compression axis 6 other ends, and the other end of holddown spring 7 is connected on the Stretch slipcovers 2.

The operating principle of the utility model is:

At ordinary times, the keyhole 3 on the lock body 1 is closed by hard hat 5, does not receive the influence of factors such as environment, weather, can not get into dust, sleet in the keyhole 3, avoids keyhole 3 to stop up.

In the time of need unblanking, hard hat 5 is spurred the other end compression holddown spring 7 of cap compression axis 6 downwards; Make hard hat 5 around 6 rotations of cap compression axis, expose fully, can unclamp hard hat 5 until keyhole 3; Cap compression axis 6 resets under the elastic force effect of holddown spring 7, can insert key unlocking.After the use, lock body 1 is locked, spur hard hat 5 downwards, second groove that rotates on the hard hat 5 is relative with the seam on the through hole 4, unclamps hard hat 5, and hard hat 5 cuts out through hole 4 under the elastic force effect of holddown spring 7.

The utility model be substitute the applicant in application on November 7th, 2008, the patent No. is the former common padlock of 200820210134.6 " a kind of anti-prying and anti-shearing lock ", its effect is better.
