Abstract

The utility model discloses a lock tongue structure, which comprises a lock tongue; an external sleeve and an internal sleeve, wherein the external sleeve is sheathed outside of the internal sleeve and can be comparatively rotated to the internal sleeve and at least one spiral groove with the same revolving direction is arranged on the sleeve wall; at least one axial groove that runs through the sleeve wall is arranged on the internal sleeve wall; and the lock tongue is movably positioned in the internal sleeve and stretches out from one end of the internal sleeve, on which at least one blocking column is arranged that stretches out from the axial groove in a radial direction and then is blocked in the spiral groove. By adopting the above structure, the utility model not only can be well connected with the electromotor to form an electromotor lock, but also can be connected with the conventional locking core structure to form a new mechanical lock.

Description

A kind of dead bolt structure

Technical field

The utility model relates to the lock construction parts, is specifically related to a kind of dead bolt structure.

Background technology

Existing lockset generally is made of lock core structure and dead bolt, and lock core structure and dead bolt interlock are provided with, and promptly when masterpiece is used for lock core structure, can drives dead bolt and finish locking or unlocking action.Yet, because existing dead bolt is generally the passive-type integral type member that needs by the lock core drive, therefore, when lockset need be realized motorized, will can realize lock core structure transformation, and limit by the composition of lock core structure and volume, often the structure of modification that carries out is difficult to the effect that reaches desirable.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of dead bolt structure simple in structure is provided, and it both can well connect with motor drive mechanism realizes the lockset motorized, can connect the function that realizes mechanical lock with conventional lock construction again.

For achieving the above object, the technical solution of the utility model is as follows: a kind of dead bolt structure comprises dead bolt; One outer sleeve and an inner sleeve are arranged, and outer sleeve is sheathed on inner sleeve and also can rotates relatively outward, offers the identical spiral groove of at least one rotation direction on its barrel; Have at least one axial groove that runs through barrel on the inner sleeve barrel; Dead bolt is movably placed in the inner sleeve and can stretches out from inner sleeve one end, and at least one card post is arranged, extend radially out and be placed in the spiral groove from axial groove.When the turn outer sleeve, spiral groove can contact the card post make it vertically that groove does reciprocating linear motion, and then dead bolt is done reciprocating linear motion in inner sleeve.

Above-mentioned outer sleeve one end has the connection part that is connected with rotary lock core structure or motor drive mechanism.

The rotation direction initial angle of above-mentioned spiral groove is about 45 degree.

Above-mentioned inner sleeve one end is a blind end, has the through hole that stretches out for dead bolt on the blind end.

Above-mentioned dead bolt is a cylinder, and the footpath is a bit larger tham the external diameter of cylinder dead bolt within the inner sleeve.

Above-mentioned inner sleeve blind end outer rim forms a circle boss, and both are integrated from the outward appearance observation so that outer sleeve is inserted in the back with the inner sleeve main part.

Above-mentioned spiral groove is two, and accordingly, axial groove is two, and the card post is two.

The utility model is by adopting said structure, both can well connect with motor drive mechanism and forms the motorized lockset, can be connected to form novel mechanical formula lockset with conventional lock core structure again.

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:

The specific embodiment

As shown in Figures 1 to 4, the utility model is made up of cylinder bodily form dead bolt 1, outer sleeve 2 and inner sleeve 3.It is outer and can rotate relatively that outer sleeve 2 is sheathed on inner sleeve 3, offers the spiral grooves 21 that the identical and rotation direction initial angle of two rotation directions is about 45 degree on its barrel; Inner sleeve 3 leading sections are blind end, have on it and have two axial grooves 31 that run through barrel on through hole 33 and the barrel thereof; The footpath is a bit larger tham the external diameter of cylinder dead bolt within the inner sleeve 3, so that cylinder bodily form dead bolt 1 movable placing in the inner sleeve 3; The dead bolt leading section inserts in the through hole 33, and there are two card posts 11 end thereafter, extends radially out and is placed in the spiral groove 21 from axial groove 31.Inner sleeve 3 leading section outer rims form a circle boss 32, and both are integrated from the outward appearance observation so that outer sleeve is inserted in the back with the inner sleeve main part.Outer sleeve 2 rearward end have a connection part 22.

Extremely shown in Figure 4 as Fig. 2, when the turn outer sleeve, the cell wall contact card post of two spiral grooves makes it moving linearly in the axial groove of inner sleeve, and then drive dead bolt moving linearly in inner sleeve, the main part branch of dead bolt stretches out from through hole in the motion process, when moving to extreme position, the extension elongation maximum of the main part of dead bolt, the duty of this moment is lockup state.Otherwise, reverse turn outer sleeve, then the main part of dead bolt is in through hole income inner sleeve, and when arriving another extreme position, the main part of dead bolt is taken in the inner sleeve fully, and the duty of this moment is opening.

Application Example 1

As shown in Figure 5, should be with among the embodiment, after the rotary lock core structure 5 of dead bolt structure 4 and routine links together by the connection part on the outer sleeve rearward end, promptly form a kind of novel mechanical formula lockset, have and the suitable result of use of conventional mechanical formula lockset.

Application Example 2

As shown in Figure 6, dead bolt structure 4 can connect with motor drive mechanism forms the motorized lockset, and that the form of structure of motor drive mechanism can have is multiple.Should use among the embodiment, motor drive mechanism is made up of motor 51, distance type control circuit 52 and remote controller 53.The power transmission shaft of motor 51 is connected with the connection part of dead bolt structure 4.After instructing to the distance type control circuit by the remote controller output function, distance type control circuit drive motor is just being made or counter steer rotates, and then the turn that drives outer sleeve makes the driving of dead bolt be able to be controlled by remote controller, realizes the effect of lockset motorized.

The form of structure of above-mentioned motor drive mechanism is not limited to use the described form of embodiment, and other motor drive mechanism that can realize constructed effect should be prior art, describes in detail no longer one by one at this.
