Abstract

The utility model relates to a locking hole protector, particularly a locking hole protection device. A transversal push-pull rod and a longitudinal torsion shaft which are perpendicular mutually are arranged in a shell, and the longitudinal torsion shaft faces to the locking hole; the transversal push-pull rod and the longitudinal torsion shaft are respectively sheathed with return springs, and the inner ends are all provided with elastic opening clamps; the end heads of the elastic opening clamps are provided with clamping grooves which are clamped with key pieces; the inner end of the transversal push-pull rod is connected with a movable guard sheet for shielding the locking hole; the movable guard sheet is sheathed in a sliding groove in the shell, and one side end of the shell close to the transversal push-pull rod is provided with an aisle groove with a key inserting hole; the aisle groove in the shell is in communication with the position of the longitudinal torsion shaft. The utility model has the advantage of theft protection performance of a reinforced lock; the locking hole can be protected from exposedness directly; the key must be loaded to open the lock via the locking hole protector; thus, the utility model prevents the existing locking hole from being the exposed effectively and the hidden danger of being stolen and unlocking.

Description

Protector for lock hole

Technical field: the utility model relates to a kind of lockset annex, particularly Protector for lock hole.

Background technology: existing various locks, as family expenses door lock, safety cabinet lock, lock for motorcycle etc., lockhole directly exposes, except that supporting key operated of available lock itself, also easy-to-use steel wire, iron plate, the master key cover is opened, even open after can filling in flexible glue and so on material, there is serious potential safety hazard.

Summary of the invention: the purpose of this utility model is to provide a kind of device, and the lockhole of the existing various locks of protection does not expose, and must send into key by this device and just can unblank.

Technical solution of the present utility model is a kind of Protector for lock hole; it is a kind of lockhole protector; it is by being provided with mutually perpendicular horizontal pull bar and vertical torsional axis in the housing; vertically torsional axis is over against lockhole; laterally respectively be set with back-moving spring on pull bar and the vertical torsional axis; each flexible opening folder on the inner; there is the draw-in groove that clamps key piece elastic opening folder termination; laterally inner connection of pull bar blocked lockhole active catch bluff piece; the active catch bluff piece is sleeved in the interior slippage slot of housing; housing has key insertion hole and passageway groove near a side of horizontal pull bar, and the passageway groove is communicated to vertical torsional axis place in housing.

The specific embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of Protector for lock hole, it is used to protect lockhole directly not expose, and strengthens the theftproof performance of lock, and it is loaded on when using on the door of lockhole one side, or on the lockhole one side object of the object of dress lock.

Protector for lock hole is by mutually perpendicular horizontal pull bar [2] and vertical torsional axis [3] are set in the housing [1]; referring to accompanying drawing 1; 2; vertically torsional axis [3] is over against lockhole [12]; horizontal pull bar [2]; vertically be respectively installed with back-moving spring A[7 separately on the torsional axis [3]] and B[8]; referring to accompanying drawing 5; 6; each have elastic opening folder [16] and [17] on its inner; elastic opening folder [16] elastic force is bigger; elastic opening folder [17] elastic force is less; elastic opening folder [16]; [17] termination has the draw-in groove E[9 that clamps key piece respectively] and F[10]; laterally pull bar [2] the inner connects lockhole active catch bluff piece [6]; active catch bluff piece [6] by the chute above it [11] be set in chute in the driving lever [13] that is fixed in [11] on the horizontal pull bar [2] connect with horizontal pull bar [2]; lockhole retaining bluff piece [6] is sleeved in the interior slippage slot [19] of housing [1]; bluff piece one end is connected on the housing [1] through spring [14]; housing [1] has concave station rank [20] near a side of horizontal pull bar [2]; referring to accompanying drawing 1; key insertion hole [21] and passageway groove [22] are arranged on the concave station rank [20], and passageway groove [22] is communicated to vertical torsional axis [3] and locates in housing [1].

The operating principle of the utility model Protector for lock hole is that in the time of need unblanking, axle [3] is vertically turned round in extraction, makes horizontal pull bar [2] removable (otherwise lockhole bluff piece [6] limits it and moves), and moves to maximum shift position outward.Unclamp and vertically turn round axle [3], key is inserted from key socket [21], the anterior major part of key enters the key draw-in groove E[9 on the horizontal pull bar [2]].Axle [3] is outer to be pulled to maximum position vertically turning round again, and red-label C is alignd with red-label D on the Protector for lock hole housing [1].Inwardly push away horizontal pull bar [2], the elastic force that adds upper spring [7] A makes horizontal pull bar [2] promote towards the lockhole direction, key is admitted to the key draw-in groove F[10 that into vertically turns round on the axle [3]], inwardly axle [3] is vertically turned round in pushing, add the elastic force of spring B [8], make vertical and turn round axle [3] and move to lockhole [12] direction.With pulling moving horizontal pull bar [2], make it to break away from key simultaneously; This moment lockhole and key to send into locality vertical, must reverse and vertically turn round spool [3], key is pushed lockhole.In order to guarantee that horizontal pull bar can send, get key reliably, laterally pull bar [2] is gone up live splint [16] folder power and must be gone up the folder power of live splint [17] greater than vertically turning round axle [3].

The lockhole bluff piece [6] that links to each other with horizontal pull bar [2] sets back this moment, and it covers lockhole when moving outside horizontal pull bar.

In the lockhole outside, 2 or 4 elasticity tongues [15] are set, shown in Fig. 4,5.In order to remove the flexible glue class material that adheres on the key.

When key operated or lock when finishing, vertically turn round axle [3] and be drawn out to outer maximum position, rotate again, make that red-label C aims at D on it.At this moment, promote horizontal pull bar [2] and allow it bite key, then, be drawn out to maximum position, the position when promptly inserting key is unclamped and is vertically turned round axle [3], takes out key from key socket [21], promptly finishes one and opens, locks overall process.

Protector for lock hole avoids keyhole directly to expose, and as much as possible limits his human other things except that key and unblanks, and improves the safety of lock, the relative uniqueness that lockset is had have only this lock key to open.

Protector for lock hole is the patron saint of lockset; with compatibilities such as family expenses safe-guard door lock, lock for motorcycle, safety cabinet locks; make lockset that real safety be arranged, also can on existing door lock, add one and have the lock of Protector for lock hole, and make two to be locked in an inboard and to connect like latch with connecting rod.The people locks first lock at the outdoor available lock that adds, play to be equivalent to the effect of dark bolt, greatly prolong the time of being locked by people's pirate of the open, possibility with foreign matter pirate of the open lock has been dropped to minimum point, if link to each other, can also prevent to cut and unblank, therefore with the infrared heat alarm, the design's market prospects are extremely wide, must greatly welcome for each family.

The utility model manufacturing is simple, and simple to operate.Can be existing every Yishanmen the market demand that the lock of Protector for lock hole is housed is provided again.
