Description

Combination lock limit lock

Technical field:

The utility model relates to a kind of combination lock limit lock, is used for the locking of combination lock, belongs to the hardware ﹠ tools technical field.

Technical background:

Before the utility model was made, in prior art, the general limit lock of combination lock mainly was to adopt compositions such as lock housing body, dead bolt, latch hook, spring.This kind structure limit when locking lock, when combination lock loam cake and lower cover close the back, to allow lock tongue embed the latch hook groove with the subordinate latch hook of pressing, combination lock limit lock is with regard to pinning.When combination lock limit lock was opened, mobile dead bolt, dead bolt just left the latch hook groove, under the effect of spring force, the latch hook unlatching of pivoting.Bigger owing to using than strong spring unlatching sound, to use the hand latch hook during locking, seem that concerning the combination lock of top grade some is uncivil, and get to hand easily, cause use dangerous.

Technology contents:

The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation, rationally is provided, and is safe and reliable, and it is convenient to open locking, low cost of manufacture, and can play the combination lock limit lock of secure lock combination lock.

The utility model adopts locking ball 8 and lock core latch 7 to load onto spring respectively to pack in the lock core 6, and be installed in the lock core shell 16 of limit lock shell 10, commentaries on classics tongue 3, rotor plate 1 are loaded onto torsion spring 11 respectively, spring divides in the carrier base 11,12 that is installed in limit lock shell 10 in addition, lock slide plate 5, locking post 2 are installed in the lock shell 10 of limit, and connection presses.

The specific embodiment:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described.

The utility model installs locking ball 8 and lock core latch 7 respectively in the lock core 6 of packing into behind the spring, the more above-mentioned parts that assemble is installed in the lock core shell 16 of limit lock shell 10.Install torsion spring, spring and pivot pin respectively and put into limit lock shell 10 carrier base 11,12 separately changeing tongue 3 and rotor plate 1, lock slide plate 5 is contained in the lock shell 10 of limit and refills locking post 2 and the spring and the connection that presses, after pressing should and the limit lock 10 on shell certain glade plane space arranged, can allow the lock slide plate drive the locking post and in the lock shell groove of limit, vertically move easily.

The operating principle of the utility model combination lock limit lock:

Figure 2 shows that the lock-out state of combination lock:

Close upper box lid, latch hook 4 (being fixed in the combination lock loam cake) overcomes the torsion spring power of changeing on the tongue, impelling commentaries on classics tongue 3 its square holes of rotation to screw in changes in tongue, goes to spacing position (case lid closes tightly up and down) locking post 2 and embed the commentaries on classics tongue under the effect of elastic force, and lock with regard to secure lock on the utility model combination lock limit.For reliable this limit lock that guarantees locks; as long as inserting lock core 6 its inclined-planes with this lock key 9 pulls pin to lock core latch 7; 180 ° of lock cores turn clockwise; make the locking protection projection 13 that is shaped on the lock core go to the locking protection hook 14 that is shaped on the locking post; so just limit vertically moving of locking post, guaranteed can not opening of the utility model combination lock limit lock.Locking ball 8 ejects in the lock housing groove that falls into limit lock shell 10 simultaneously, makes it that better location sensation (feel and phonoreception) be arranged, and also stops the lock core inhour to be rotated.The locating piece 15 that is shaped on the lock core has been run into the limited block 17 that is shaped on the lock core shell 16 simultaneously, has obtained reliable location, and the rear lock core latch that guarantees to pull key can insert lock core shell groove location smoothly, guarantees that reliably lock core does not rotate.

Shown in Figure 3:

If will open this combination lock limit lock, pull out locking post 2 before combination lock is opened and located.Its process is inserted this lock key 9 for the limit lock pin, and its inclined-plane pulls out lock core latch 7,180 ° of counter-clockwise rotary locking cylinders.Make the locking protection projection 13 on the lock core protect hook 14 away from the locking on the locking post 2; vertically move lock slide plate 5 then; the locking post that is riveted on just moves to spacing position together; rotor plate 1 makes the locking post be positioned under the effect of spring force; the locking post just can't oppositely move, and the upper box lid of the utility model combination lock limit lock just can be opened at any time.

Shown in Figure 4:

The combination lock opening, open upper box lid, latch hook drives to be changeed tongue 3 rotations and impels rotor plate 1 to rotate, make locking post 2 lose the location, move forward under the effect of locking post spring force, the latch ramp end is bumped above three actions in commentaries on classics tongue side limited (latch hook 4 left and changeed tongue this moment) and has just been finished the utility model combination lock limit and be locked in the whole course of action of opening and automatically locking on the combination lock.

Compared with the prior art the utility model has the following advantages:

1. simple, compact and reasonable for structure, low cost of manufacture; 2. as long as the case lid that slightly firmly closes, the limit lock just can automatically lock when automatically locking, as long as vertically move the lock slide plate during unlatching, the upper box lid of combination lock just can be used to open, when opening or lock latch hook, shell is locked on the limit does not have spring; 3. the civilization of unblanking does not need the hand latch hook, and promptly safety is convenient again; 4. the lock housing global design becomes cambered surface, and appearance integral is strong, and is elegant in appearance.
