Description

Roller type dead bolt positioner

The utility model relates to a kind of security door dead bolt detent mechanism, relates in particular to a kind of roller type dead bolt positioner.

General safe-guard door lock normally utilizes an oblique tongue to realize the lock core location of many dead bolts and the common locking at the back door of unblanking.There is very big mechanical pressure usually in this locate mode between the dead bolt hole on oblique tongue and the doorframe, must just can overcome oblique tongue and the force of sliding friction of lock between the frame applying bigger mechanical torque on the key when opening the door, sometimes even have to door-plate is additionally exerted pressure and could be opened door.This force of sliding friction also can aggravate the mechanical wear between dead bolt and the dead bolt hole, and the positioning accuracy of door lock is descended.More and more automatically lock security door at present and generally adopt single lock structure, cancelled oblique tongue, the mechanical pressure that is added in originally between oblique tongue and the dead bolt hole directly has been added between cylinder dead bolt and the dead bolt hole now.Modern security door is in order to increase the sealing performance of door, generally adopted rubber gasket, mechanical pressure between cylinder dead bolt and the dead bolt hole is increased, thereby when opening the door, bigger mechanical torque must applied on the key, the phenomenon of key fracture happens occasionally, and has all brought very burden for user and producer.Because the uncertainty of this stiction size, if door lock adopts driven by power, motor then is difficult to adapt to this significantly static pressure to be changed, and makes the design of drive system and power-supply system become very difficult.

The purpose of this utility model is to provide a kind of novel roller type dead bolt positioner, improve the deficiency of existing locate mode: the sliding friction between location dead bolt and the lockhole is become rolling friction, thereby reduce the mechanical friction power between location dead bolt and the lockhole significantly, reduce mechanical wear; Adopt the dead bolt structure not isometric, that the top is circular platform type simultaneously, can reduce requirement greatly the dead bolt positioning accuracy.

The purpose of this utility model is achieved in that a kind of roller type dead bolt positioner, comprising:

Have location dead bolt hole and main dead bolt hole on doorframe, the diameter of location dead bolt hole is more bigger than main dead bolt hole.Location roller bearing and roller support constitute the dead bolt locator, and are installed in the back of the location dead bolt hole of doorframe.With screw the dead bolt fixed base plate is installed on the door-plate, location dead bolt and main dead bolt are installed on the dead bolt support.The garden cylindricality profile of the garden arc profile of roller bearing and location dead bolt is complementary.Dead bolt on the door is made up of location dead bolt and main dead bolt, wherein locatees dead bolt and omits length than main dead bolt, and the head of location dead bolt is done in the arc-shaped, and the head of main dead bolt is made the truncated conical shape of suitable length.

When locking a door, because the location dead bolt is the longest, at first from door-plate, skid off, add that the location dead bolt hole on the door-plate is bigger, the location dead bolt is easy to enter into the dead bolt locator that is contained in this position on the doorframe, owing to be subjected to the constraint of dead bolt locator location roller bearing, the location dead bolt can only move in the space between two location roller bearings of dead bolt locator, thereby realizes the accurate location to the dead bolt group.Suitably the length of Design Orientation dead bolt and main dead bolt just can guarantee dead bolt after fully accurately locating, and main dead bolt just begins to enter the main dead bolt hole on the doorframe, and when dead bolt skidded off specific length from door-plate, the locking work of door was finished.Because main dead bolt hole can be accomplished and main dead bolt between relatively more accurate cooperation, in case door is subjected to the invasion of external mechanical force, main dead bolt just can play a role immediately.

Because two location roller bearings can rotate flexibly, so dead bolt is going deep in the process in the dead bolt locator gradually when the location, only has rolling friction between them.And because main dead bolt leading section is designed to the truncated cone-shaped structure of certain-length, makes winner's dead bolt in the process that from door-plate, skids off, can machinery not take place with dead bolt hole substantially and contact, just sliding friction can not take place substantially yet.Opening the door is the inverse process of closing the door, and along with dead bolt is regained in door, main dead bolt at first leaves main dead bolt hole, and at this moment whole door-plate is just temporarily by dead bolt location, location.Along with the location dead bolt also leaves the dead bolt locator gradually, door-plate outwards rotates under the elastic force effect of seal gasket gradually, the location dead bolt can contact to some extent with the location dead bolt hole, but because location dead bolt hole diameter is bigger, at this moment the elastic force of seal gasket has obtained release to a certain degree, so the force of sliding friction between location dead bolt and the location dead bolt hole is very little.

Accompanying drawing and drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the lateral view of the utility model dead bolt locator;

Fig. 3 is the A-A sectional view of the utility model dead bolt locator.

Fig. 4, Fig. 5, Fig. 6, Fig. 7 are the installation and the action schematic diagrames of the utility model dead bolt locator and dead bolt.

Wherein, 1-doorframe, 2-door-plate, 3-location roller bearing, 4-main dead bolt, 5-location dead bolt, 6-dead bolt positioning plate, 7-screw, 8-pick-proof limit, 9-seal gasket, 10-location dead bolt hole, 11-main dead bolt hole, 12-roller support, 13-dead bolt support.

Seal gasket 9 is housed on doorframe 1, and on doorframe 1, have location dead bolt hole 10 and a main dead bolt hole 11, the dead bolt locator that is made of location roller bearing 3 and roller support 12 is installed in the back of the location dead bolt hole 10 of doorframe 1 by suitable mode, by screw 7 dead bolt fixed base plate 6 is installed on the door-plate 2, location dead bolt 5 and main dead bolt 4 are installed on the dead bolt support 13, also are provided with pick-proof limit 8 on door-plate 2.

The location roller bearing 3 of the dead bolt locator that the utility model adopts can rotate on roller support 12 flexibly, the cylindrical shape of its stage casing circular arc profile and location dead bolt 5 is complementary simultaneously, make that location roller bearing 3 can freely rotate when location dead bolt 5 inserted the dead bolt locator, can also keep bigger constraint to location dead bolt 5 simultaneously.As can see from Figure 4: location dead bolt hole 10 is bigger than the diameter of main dead bolt hole 11, has also done bigger chamfering on the dead bolt hole 10 of location.Can also see from Fig. 4: the main dead bolt 4 that is contained on the dead bolt support 13 is different with the length of location dead bolt 5, location dead bolt 5 is longer than main dead bolt 4 outlines, locate dead bolt 5 simultaneously and have slick and sly head, be illustrated as and locate dead bolt 5 and main dead bolt 4 residing positions when door is opened.At closing time, the dead bolt group skids off from door-plate 2 under the driving of driving mechanism, because the diameter of location dead bolt hole 10 is bigger, the reasonable Arrangement of dead bolt locator in addition, location dead bolt 5 can be easy to enter in the dead bolt locator, Figure 5 shows that the dead bolt group position when location dead bolt 5 is just accurately located, as can be seen from the figure, at this moment and bigger move place still arranged between the main dead bolt hole 11 because the design of the circular platform type of main dead bolt 4 front ends.Sight when Fig. 7 puts in place fully for dead bolt skids off, as seen from the figure, because the pinpoint result of dead bolt locator, main dead bolt 4 and main dead bolt hole 11 can design less spacing, be subjected to external force to do the time spent at door-plate, this is very favourable to the external force resistance effect of bringing into play main dead bolt 4, makes that location dead bolt 5 is unlikely in this case to bear too big applied external force separately.Fig. 6 is that location dead bolt 5 has just broken away from the dead bolt locator in the process of opening the door, sight when also not breaking away from doorframe, at this moment locate dead bolt 5 meetings and locate dead bolt hole 10 and come in contact and then between them, produce sliding friction, but because door-plate has outwards moved certain distance, seal gasket 9 has discharged part elastic force, at this moment sliding friction has reduced, and therefore, can not produce great sliding-frictional resistance.

Location roller bearing 3 on the roller type locator also deformable is the structure of location ball.Roller type dead bolt positioner can be directly and door on main lock cooperate, also can cooperate with other auxiliary lock point installation one or several.

Advantage of the present utility model:

1. the sliding friction between dead bolt and the dead bolt hole is become rolling friction, can fundamentally reduce out, The mechanical resistance of closing the door makes the unlatching of door more light, reduces the fracture damage of key, user friendly making With.

2. reduce significantly the mechanical wear of parts, prolong the service life of parts, make the long-term maintenance of a body High locking precision has improved the long-term reliability of product.

3. because rolling frictional resistance is very little, the fluctuation of the absolute value of stiction very between dead bolt and the dead bolt hole Little, therefore be particularly suitable for the fluctuation of stiction is required very harsh driven by power lockset, can be big Amplitude reduces the driving moment of motor, saves the energy, simplifies the design of drive system and dynamical system.
