Abstract

The utility model relates to a turning lock, comprising a sleeve barrel and a lock core. A key hole is arranged at the center of the lock core; at least one row of pin holes penetrate into the key hole and are used for placing pushing pins; a perforation having the same diameter as that of the pin hole, a clamping pin, and a spring are arranged on the sleeve barrel corresponding to the locking position of the lock core. The utility model is characterized in that through holes used for placing the supporting pins and the spring are arranged on the sleeve barrel corresponding to the unlocking position of the lock core, and the diameter of the through hole is larger than the diameter of the pin hole. The utility model has simple and reasonable structure, the key can be easily pulled out whether the lock core is at a locking position or an unlocking position, and the utility model can be used on various occasions.

Description

Turning lockset

The utility model relates to a kind of Turning lockset, be meant a kind of rotary lock especially, when no matter core is at locking position or tripper, key all can be transferred to smoothly, so that be applied to multiple occasion, especially do not need key to cooperate and core can be able to be turned to locking condition from the release shape, quite convenient in the use.

As shown in Figure 1, traditional rotary lock, include a sleeve 10 and a core 20 constitutes, its middle sleeve 10 is provided with majority and wears 1 hole 1 for the blocking tip 30 and spring 40 settings, core 20 is provided with the corresponding tip 21 through keyhole 22 in the relative position of perforation 11, for pushing away the tip 50 setting, on sleeve 10, be provided with the through hole 12 that is same as tip hole 21 with respect to the tip 21 and diameter in addition with respect to the unlocked position of core 20, be provided with spring 40 for holding the tip 70.

When core 20 is positioned at locking position, this blocking tip 30 will be passed by the elastic force of spring 40 and enter among the tip hole 21, just between core 20 and sleeve 10, make sleeve 10 and core 20 relatively rotate, form locking condition, again when key 60 inserts keyhole 22, must make double wedge 61 on the key 60 will respectively push away the tip 50 upwards moves on the top, height by double wedge 61 distributes the end that will respectively push away the tip 50 to trim between core 20 and sleeve 10, and can make the relative released state that turns between sleeve 10 and the core 20, hold the tip 70 this moment and promptly can be subjected to the elastic force of spring 40 to pass and enter in the tip hole 21, core 20 is fixed in released state.

Yet, the disappearance of this kind lockset maximum is to desire when the release state turns to locking condition when sleeve 10 and core 20, because of being equipped between core 20 and the sleeve 10, the ejection tip 70 can't rotate, (as shown in Figure 2), must cooperate key core 20 can be rotated locking position, cause user's inconvenience greatly, also therefore a shortcoming causes the purposes of this kind lockset limited.

Main purpose of the present utility model is to provide a kind of Turning lockset, and though when core be at locking position or unlocked position, key all can be transferred to smoothly, so that be applied to multiple occasion.

The purpose of this utility model is achieved in that a kind of Turning lockset comprises that a sleeve and a core constitute, wherein the sidewall of this core is provided with at least one row's tip hole, for pushing away tip setting, be provided with respect to the locking position place of core on the sleeve and correspond to tip hole and the identical perforation of diameter, for the blocking tip and spring setting, in addition on sleeve, be provided with a row with respect to tip hole and diameter through hole, for holding the tip and spring setting greater than tip hole with respect to the unlocked position of core.

The bottom in tip hole is provided with a stop edge, in stop edge and push away a flexible member is set between the tip.

The elastic acting force of this flexible member is less than the elastic acting force of spring.

According to the technique scheme analysis as can be known, the utility model is rational in infrastructure, when the core of lockset is unlocked position and key is outwards transferred to, on the key with being that the top is moved the double wedge that pushes away the tip and must be headed in the through hole pushing away the tip, and can make key transfer to keyhole smoothly, particularly do not need key to cooperate and core can be turned to locking condition from the release state, quite convenient in the use.

Further specify as follows below in conjunction with drawings and Examples:

Fig. 1 is a sectional view of commonly using the rotary lock locking condition.

Fig. 2 is a sectional view of commonly using the rotary lock released state.

Fig. 3 is the sectional view of locking condition for the utility model.

Fig. 4 is the sectional view of the utility model after key inserts.

Fig. 5 is the sectional view of released state for the utility model.

Another is the sectional view of released state to Fig. 6 for the utility model.

As shown in Figure 3, Turning lockset of the present utility model, including a sleeve 10 and core 20 constitutes, wherein: the center of this core 20 is provided with a keyhole 22, sidewall is provided with at least one row's tip 21 and is through to keyhole 22 for pushing away the tip 50 settings, the bottom in tip hole 21 is provided with a stop edge 23, in stop edge 23 and push away and a spring element 24 is set between the tip 50 will pushes away the tip 50 and upwards hold.

Be provided with respect to the locking position place of core 20 on the sleeve 10 and correspond to tip hole 21 and the identical perforation 11 of diameter, be provided with for the blocking tip 30 and spring 40, on sleeve 10, be provided with respect to tip hole 21 and diameter through hole 12 in addition greater than tip hole 21 with respect to the unlocked position of core 20, be provided with spring 40 for holding the tip 70, this diameter that holds the tip 70 is also greater than tip hole 21 diameters, hold in the tip 70 immigration tip holes 21 and be unlikely order, in addition, the elastic acting force of spring 40 is greater than the elastic acting force of above-mentioned flexible member 24, can make to push away the tip 50 and remain in 21 inside, tip hole.

After above-mentioned structure assembling, when sleeve 10 and core 20 are positioned at the pin maintenance and put, the blocking tip 30 will be held by the elastic acting force of spring 40 and the end of the blocking tip 30 is moved in the tip hole 21, make between sleeve 10 and the core 20 and must can't relatively rotate, promptly be locking condition by the blocking of the blocking tip 30.

In addition in key 60 is inserted during the inside of key 22, each double wedge 61 can upwards the top move the blocking tip 30 to trim in the boundary (as shown in Figure 4) of sleeve 10 with core 20 by respectively pushing away the tip 50, and sleeve 10 gets final product the relative unlocked position that turns to core 20 at this moment.

As shown in Figure 5, when core 20 and sleeve 10 are positioned at the relative position of release, must move into through hole 12 inside owing to respectively push away the tip 50, therefore when key 60 was outwards transferred to, each double wedge 61 can will push away logical 12 inside in the tip 50 tops, and key 60 is taken out smoothly.

As shown in Figure 6, what deserves to be mentioned is, because this diameter that holds the tip 70 is greater than tip hole 21, therefore holding the tip 70 when core 20 is positioned at unlocked position entered among the tip hole 21 by the passing of spring 40 elastic force, core 20 can be fixed in unlocked position, thereby do not need to cooperate by key 60, core 20 can be turned to locking condition, quite convenient in the use.

In addition, flexible member 24 its main purposes of being located at 21 inside, tip hole are that prevention pushes away the tip 50 and rocks in tip hole 21, so the setting of this flexible member 24, and the action that should not hinder the blocking tip 30 is a principle, that is the elastic acting force of this spring element 24 needs the elastic acting force less than spring 40.
