Abstract
A water-proof cover unit for lock can prevent rain from intruding the lock and features that its cover has no obtacle imposed on operating lock. Said cover unit is composed of a main base, a bearing part on the main base, a first and a second recesses intervally arranged on the bearing part by a certain angle, a cover plate rotationally pivoted on main base by means of its end part and axle pin of the bearing part, an inserting hole on extended shoulder of cover plate, small stopping ball moving back and forth for reception in inserting hole, and a spring for pressing said small stopping ball toward projection direction.
Description
The present invention relates to waterproof cover for lock, it is to be used for stoping the keyhole of the lock that rainwater etc. set from the door that is arranged on outdoor instrument to enter.
Existing waterproof cover for lock is to open the 1st recess and the 2nd recess place that the certain angle compartment of terrain is provided with in the bearing portion sky of this susceptor body, enable to be housed in movably and be located at stretching out of cover plate pallet bead in the jack on the shoulder and that suppressed towards projected direction and combine with the 1st recess when the closing cap, combine with the 2nd recess opening when covering along fore-and-aft direction.
Though this waterproof cover for lock can remain on any state of closing or opening with cover plate definitely by the frictional force that acts between the 1st recess, the 2nd recess and the pallet bead, in off position down can be owing to capillarity, rainwater etc. still can be invaded.
The purpose of this invention is to provide a kind of waterproof cover for lock, it is that cover plate can not become obstacle when operable lock, can guarantee abundant sealing simultaneously when locking, can stop rainwater to be invaded really.
Fig. 1 is the oblique view that the door of the waterproof cover for lock that one embodiment of the invention relate to is being adorned in expression.
Fig. 2 is the elevation of waterproof cover for lock shown in Figure 1.
Fig. 3 is the right side view of waterproof cover for lock shown in Figure 1.
Fig. 4 is the A-A line sectional view of Fig. 2.
Fig. 5 is the B-B line sectional view of Fig. 2.
Below, be illustrated as waterproof cover for lock of the present invention and the embodiment that achieves the above object and make with reference to accompanying drawing.Waterproof cover for lock of the present invention is made up of following member: promptly, portion carves to establish ditch 9 and to carve with this ditch 9 with being connected and establishing gutter 10 and be fixed tightly in this susceptor body 2 on 1 in front; Sky is arranged on the 1st recess 2b and the 2nd recess 2c on the 2a of bearing portion of this susceptor body 2 with opening certain angle intervals; By the cover plate 3 on the pivot Zhi Zaiben susceptor body 2 pivotally of the pivot pin 4 by base end part and the above-mentioned bearing 2a of portion, 2a; Be arranged on the jack 3b on the shoulder portion 3a of stretching out of cover plate 3; Can be housed in this jack 3b movably and the pallet bead 5 that when lid is closed, combines, when lid is opened, combines along fore-and-aft direction with the 2nd recess 2c with the 1st recess 2b; This pallet bead 5 is suppressed spring 6 to projected direction.
Since lid when closing pallet bead 5 combine with the 1st recess 2b, by spring 6 pallet bead 5 is suppressed towards projected direction, thereby frictional force acts between the 1st recess 2b and the pallet bead 5, thereby cover plate 3 stably remained under the closed condition.Owing to the meetings such as rainwater that invaded by capillarity between this susceptor body 2 and the cover plate 3 are wandered by gutter 10 from ditch 9, thereby can not invade inside.
When operable lock 7, making cover plate 3 is that center steering is opened with pivot pin 4.When opening operation begins, with the conjugate pallet bead 5 of the 1st recess 2b by apply for revolution make every effort to overcome clothes spring 6 elastic force pressure and retreat in the jack 3a, removed above-mentioned combination thus.When continuing to make cover plate 3 revolutions and making it forward predetermined angular to, pallet bead 5 combines with the 2nd recess 2c, makes it give prominence to and combine with the 2nd recess 2c by the elastic force of spring 6.Therefore cover plate 3 is held in open mode, can hinder the operation of lock 7.
If cover plate 3 depressed downwards and made it revert to closed condition, then can pallet bead 5 be combined with the 1st recess 1b by process opposite when opening, thus it is held in closed condition.
In illustrated embodiment, the peristome 8 of accommodating the head of lock 7 is arranged on this susceptor body 2 along fore-and-aft direction with connecting, at the upper end of this susceptor body 2 front surface the pair of right and left bearing 2a of portion, 2a are being set highlightedly.The 1st recess 2b and the 2nd recess 2c are configured in pivot pin 4 and are on the same circumference at center, form the alms bowl shape.Jack 3b is arranged on along the length direction of cover plate 3 and stretches out on the shoulder portion 3a.Spring 6 is made of compression helical spring.Leading section at cover plate 3 is provided with the 3c of handle portion that switching manipulation is used.
