Abstract

The utility model relates to a fully sealing type code safety lock. The key hole of the existing safety lock is exposed outside, the safe performance when a key is lost or is imitated can not be ensured. A lock core is eccentrically arranged in a cylindrical lock core body by the fully sealing type code safety lock, and a blocking cover, a sleeve cylinder with a blocking sheet, a code positioning and adjusting device, etc. are additionally added to the outer surface of the fully sealing type code safety lock. A key hole can be closed by the blocking cover from the exterior. Only when a code is correctly aligned, the blocking cover can be rotated, and the key hole is exposed. The fully sealing type code safety lock has a compact and simple structure. The safety performance and the durable performance of the fully sealing type code safety lock are enhanced.

Description

Fully sealing cipher safety lock

The utility model belongs to a kind of safety lock, particularly uses the safety lock of puzzle-sealed key hole.

The safety lock keyhole that generally uses all is emerging in the outside at present, the keyhole of this form is easy on the one hand be had a mind to or is not intended to fill in foreign matter and makes tapered end be difficult to open, the more important thing is and under the key loss or the situation of being copied, promptly cannot say for sure its safety by other people, 92109125 patent applications disclose a kind of safety lock with puzzle-sealed key hole, embodiment 1 blocks keyhole internally in this application file, be that the keyhole inlet is still exposed externally, be inserted into foreign matter easily.Embodiment 2 has sealed keyhole from the outside with catch, but its password location adjustment member and lock core are separated into two parts, complex structure not only, and not compact, volume is big, and not attractive in appearance.

The utility model is intended at the aforementioned techniques weak point, design a kind of can be from the outside whole sealed key holes, can make password location adjustment member and lock core partly be integrated the simple full-enclosed cipher lock of compact conformation again.

The technical solution that realizes above-mentioned purpose is: common lock core is vertically run through the fastening diameter that is loaded on be not less than in the cylinder-type lock core body of 2 times of lock core diameters, lock core is positioned at lock core body central axis one side, outside the end face of keyhole is exposed in the lock core body front portion, a door is set, the eccentric open keyhole that can expose keyhole after rotating that is provided with on the door, door rear portion and one is enclosed within the sleeve relative fixed that lock core body is outer and can be slidingly matched and rotate, have the catch slotted eye that penetrates barrel on the sleeve, the lock core body surface also has and sleeve catch slotted eye position, the corresponding catch groove of size, be provided with the catch that can push freely or release in the space that two hole slots overlap, sleeve is provided with the password positioning adjustment device of the groove alignment catch slotted eye that is provided with on the inwall that it can be slided outward with being slidingly matched.

The operating principle of this device is: the lock core body of dead bolt is relatively-stationary with door in the control lock body, because catch is positioned at the space that lock core body catch groove overlaps with sleeve catch slotted eye, so the normal conditions lower sleeve is pinned and can not rotate by catch, nature can not rotate with the relatively-stationary door that has blocked keyhole of sleeve, when the groove alignment catch slotted eye on the password location adjustment ring inwall that will be enclosed within by the adjustment of password location outside the sleeve, twist door again and give sleeve one rotatory force, can catch be pushed in the groove of outer password adjustment ring inwall by the rotatory force that sleeve lining produces, sleeve can be rotated, thereby turn door to the position of exposing keyhole.

This safety lock has not only all sealed keyhole from the outside, improved the safety of lock, and simple and compact for structure, and password adjustment member and lock core are integrated, and volume is little, and is handsome in appearance, has improved the durability of lock, and making and installation are also very convenient.

Now in conjunction with the embodiments the present invention is further described.

Embodiment 1: present embodiment is identical with common latch by the dead bolt and the lock body part of 21 controls of lock core 1 rear portion plectrum, does not omit and draws.The present invention is primarily aimed at lock core and has partly carried out architecture advances, common lock core 1 is vertically connected fastening being loaded in the cylinder-type lock core body 2, lock core diameter is slightly less than the lock core body radius and is positioned at lock core body central axis one side, outside the end face of keyhole 22 is exposed in lock core body 2 front portions, a door 4 that can rotate is set, in door semicircle scope, establish the open keyhole 5 that to aim at keyhole 22, the sleeve 7 that lock core body 2 peripheral hardwares one can be slidingly matched and rotate, see Fig. 2, Fig. 3, sleeve outer wall 7 is a step, its front end is the high step identical with the door diameter, jackscrew 6 passes step and is screwed into door 4 with the two relative fixed, vertically have the catch slotted eye 8 that penetrates barrel on the sleeve, lock core body 2 surfaces also have and sleeve catch slotted eye 8 sizes, the corresponding catch groove 3 in position, 3, adorn a catch 9 that can push release freely in the relative space of 8 liang of hole slots, catch cross section Lower Half is approximate del, first half two edges are parallel, when the catch lower end is positioned at catch groove 3 bottom lands, the upper end is positioned at corresponding sleeve catch slotted eye 8, the outer wall position that sleeve 7 is positioned at catch slotted eye 8 is with side by side that ring 10 is adjusted in the password location that is slidingly matched and ring 12 is adjusted in the location, two the ring inwalls vertically have respectively can with sleeve catch slotted eye 8

corresponding detents

11 and 13, the groove size should satisfy has only two grooves that catch 9 is inserted, and its degree of depth is not less than the degree of depth of lock core body catch groove 3.The external diameter that is positioned at anterior password location adjustment ring 10 is located the external diameter of adjusting ring 12 thereafter greater than being positioned at, adjust ring 10 front portions withstands on the sleeve 7 vertical stand terraces with being slidingly matched, the circumferentia that exceeds step is marked with this degree of password, be screwed with jackscrew on the vertical stand terrace that rear end face forms and stir pin 14, be screwed with jackscrew on adjustment ring 12 outer walls and stir pin 15.

The cross section of lock core body catch groove 3 is similar to catch 9 Lower Half cross sections, be del, sleeve catch slotted eye 8 cross section two edges lines can be parallel (Fig. 4), also can be at a subtended angle (as Fig. 5) slightly on the sleeve outer wall direction, be beneficial to the release catch like this, catch cross section first half two edges line also can be at a subtended angle slightly on the direction of outer wall.

Embodiment 2 is referring to Fig. 6, on the vertical annular end face of the anterior high step of sleeve 7 outer walls, be provided with the identical at interval recess 16 of right quantity, (jackscrew 6 is lower than end face and also forms a recess), the password location is adjusted ring 10 inwalls and is provided with and the corresponding step of sleeve 7 outer wall front ends, be provided with at itself and sleeve 7 on the step surface of vertical stand terrace sliding-contact of recess 16, one recess 17 also is set, spheroid 18 is pressed into this recess by spring 19, the starting point 23 that one projection can touch with hand is set on simultaneously adjusting the scale of ring 10 front end faces in the password location, the anchor point 24 that one projection can touch with hand also is set at door 4 edges, secretly do not see at light under the situation of scale, can aim at the anchor point of door edge protuberance by touching the starting point that to adjust ring scale projection earlier, rotate then and adjust ring 10, because when being located at the recess that its anterior spheroid 18 revolutions are provided with to sleeve 7 vertical stand terraces, promptly can be sprung into once, send the vibration and the sound, so just can open keyhole with feel or sound check mark location.
