Description
The utility model relates to a kind of door lock.
As everyone knows, the installation of door latch structure except aiming to provide a body closed orientation, also can utilize internal lock that a body can not be opened by the outside, so door lock is because the usability difference also has very big difference in its function design.Generally speaking, has the door lock of locking function, because of its latent close safety of using co-relation housing or room, so the consideration of its structural design and lockset intensity is the survivable and difficult surreptitiously property opened of definitely paying attention to door lock.Therefore, the door lock that is sold at present, can be divided into lock construction and not reach lock construction two big classes, wherein, last lock construction still is distinguished into one section, two sections or the above locking structure of multistage, and its locking is the door lock of section the more, and structure is formed and designed promptly more complicated, and price also is quite expensive, so be to use the door lock at the gate mostly.And general room door, the door lock of lavatory or access door, then based on the measurement of using on needs and the price, be to adopt one section locking function of tool only or do not have the horn lock of locking function mostly, wherein, the horn lock of tool locking function, utilize in the concentric transmission, the outside fix tapered end, establish one by press button in the inner lock head end nipple, when pressing down, can provide the axle center braking action by press button, to stop the rotation of contracting in the outer tapered end control lock tongue, make outer tapered end can not finish opening door operation, must will locate from locking by the press button bullet, just can make the axle center transmission reply normal action via the inner lock head turn, but the difficult tool locking of the structure of this kind door lock, but because of it can back down last locking bit by press button by lock core hole position, the outside, and stolen easily opening, so its locking function still has the anxiety of safety.As for a horn lock of not having a locking function, then be two-way all door locks of turn-off arbitrarily, because the application of locking function can not be provided,, only do the positioning control of door body closure so be mostly to be installed on the door body that need not pay attention to safety and confidentiality; In addition, the lock of commonly using the horn lock is normally integrated, make so only can produce the moulding of single color and luster or single material, so that it lacks aesthetic in appearance.Obvious traditional simple door lock, reach in the use still have on the structure design to be strengthened with the improvement.
The purpose of this utility model provides a kind of safe and reliable, simple and practical door lock.
For achieving the above object, the utility model is taked following design scheme: this door lock is by the flexible dead bolt of emergence end tool, be embedded within the axle sleeve in the groove and press on the spring, the slotted eye, the hollow slots that run through axle sleeve and dead bolt again with axle, can control the location of dead bolt, and the axle two ends are established liner, lock in passing respectively and are pulled behind the lock of sheet, join with the end alveolus of inner lock head and outer tapered end, and lock the side screw by a locked bolt and produce and to be tight against effect, lock then is to utilize positioning bolt to lock respectively in the medial and lateral of door body; It is characterized in that: dead bolt hollow slots inner edge is provided with the projection that is the top of the horn shape, and axle is the arc edge body that is provided with the angle breach with the stage casing, and the generation normality is located (being the kayser situation of dead bolt end evagination) with the dead bolt projection is chimeric, and two ends is set as the square bar of thread segment; Be fixed in lock in the inboard lock sheet of pulling, it is a central round-meshed wafer body, its circular hole left and right side sets up symmetrical hole slot separately, and be that the center dashes left and right side and is recessed into shape with the hole slot, form a salient point in inner edge hole slot side, control strip is utilized towards the recess difference be set in the hole slot, its medium pore still is made up of arc and square hole, the hole lateral margin has the calixconcavity that cooperates salient point in addition, side and extend be bending the pull handle projection in interior lock outer rim.Described door lock is set as ring body and seat surface two parts with the lock branch.Described door lock is pulled at lock and is installed a volute spring between sheet and the lock.
Owing to adopt above technical scheme, promptly provide dead bolt displacement start, and can make door lock produce the effect of locking via the braking of control strip by the axle configuration; It utilizes the angle breach design of axle stage casing arc edge body, and the hollow slots inner edge that dead bolt cooperates axle to place has a top of the horn shape projection, can be via tapered end mandrel mode, make the chimeric disengaging of angle breach and projection, become arc edge surface conflict projection peak, because revolving the position, axle cause projection to produce displacement difference, thereby the variation of contracting in having of this displacement official post dead bolt, finish the lock control operation of opening the door; But if will be installed in the control strip of locking on the sheet of pulling in the interior lock, outwards pull formation square hole engages the location with the square bar of axle, this moment, square bar promptly was subjected to the square hole system of arresting and can't turn, therefore also can not implement to rotate with the tapered end of axle interlocking, what form dead bolt stop ends the lock effect, has that door lock is controlled, the enforcement effect of the simple and easy effect of locking is simplified and effectively produced in moulding.
In addition,, make lock see effect to strengthen outside the lock, therefore have the use effect of promoting lock moulding, installing aesthetic feeling by ring body, the seat surface winding moulding of different color and lusters because the utility model can be set as the lock branch ring body and seat surface two parts.
Because the utility model can install a volute spring between locking sheet and lock, the lock sheet of pulling is not closely pasted with lock under the spring tension effect, to reduce control strip is formed resistance, therefore reach the enhancement control strip and pull and support smooth slippage, laborsaving enforcement effect.
Have, because the utility model locking effect of utilizing control strip sidesway mode to be produced, the location of tapered end is located outside again, and surreptitiously the opening of locking property releasing has the result of use of the implementation safety of guaranteeing to lock then.
The utility model is described in further detail below in conjunction with accompanying drawing
