Description

Handle type lockset with improvement rotating shaft collar

The utility model relates to a kind of handle type lockset.

Press, can see on the market at present and lockset in, the fixed lockset that comprises the first generation, and do not have the structure of interchangeable core, that is in a single day the lockset of this fixed is installed on after the door-plate, if will change lockset suffers deathwatch's problems such as copy with the key that prevents the public place, promptly whole lockset must be removed, use and be unsuitable for regular replacing.

And the lockset of the second generation, changed though core can be taken out, yet, this interchangeable core formula lockset, the distinguishing that does not have direction, and if be applied among the handle type lockset, can not be along with the rotation direction difference of door, and determine among the core the card pearl towards, so the installing of the interchangeable core formula handle type lockset of this second generation, it is applied in left-handed door or the dextrorotation door, promptly can't differentiate key towards, the latch of key should be faced upward or downward to insert actually and just belong to correctly in the keyhole, and this shortcoming for the user, if be in the middle of the comparatively dangerous dark or unfamiliar environment, then caused sizable inconvenience, for this reason, this creator once designed a kind of this lock structure towards problem that solves, and announced the 31730 No. six [the driving section improvement of interchangeable core formula handle type lockset], and can be according to the in addition conversion of rotation direction of door, no matter the rotation direction that makes door is for dextrorotation or when left-handed, latch that all can the erbium spoon towards on open lockset, reach the remarkable efficacy of ease of use.

This one [driving section improvement of interchangeable core formula handle type lockset], can cooperate referring to Fig. 5, shown in 6, wherein, this driving section is by handle 60, be positioned at the interchangeable core 90 of handle 60, the rotating shaft 70 that is connected with handle 60 nose bar portions and the collar 80 that is positioned at rotating shaft 70 front ends are formed, rotating shaft 70 forms core draw-in groove 71 towards handle 60 directions, 72, and form larger-diameter blocking part 81 at the collar 80 front ends, form groove 83 on the projecting ring section 82 of the collar 80, projecting ring section 82 downsides form protuberance 84, wherein, rotating shaft 70 end faces are the two corresponding core draw-in grooves 71 that are provided with, 72, and can be according to rotation direction the rotation collar 80 and different core draw-in grooves 72 of door, 73 correspondences, therefore, no matter the design of left-handed door or dextrorotation door, the collar 80 all can rotate 180 degree thereupon, and make protuberance 84 can be plugged at arbitrary core draw-in groove 71, in 72, again core 90 is inserted in the open-work 61 of handle 60, make the projecting ring section 82 of the collar 80 can be coated on lock core rod 91 peripheries of core 90, as shown in Figure 6, at this moment, key 94 inserts keyhole 92 and rotates, and make the clip projection 93 of core 90 transfer to, and clip is finished the replacing assembling of core 90 in projecting ring section 82 rear ends of the collar 80.

This structure design, though can reach the purpose that conversion turns to, no matter make that the lock core rod 91 of core 90 is left, the design of dextrorotation door, all can allow the latch 941 of the key 94 opened, form same towards, and can make things convenient for the user to open lockset, yet, the positioning design of the collar 80, but only there is protuberance 84 to insert the core draw-in groove 71 of rotating shaft 70, in 72, and can only determine that the collar 80 can be not left, right rotation, desire can not guarantee that the collar 80 can not hauled out totally by axial strength, because, when the clip projection 93 of core 90 is transferred to, be projecting ring section 82 ends of clip in the collar 80, and the collar 80 insert in the rotating shafts 70 axially, but without any clip positioning action, for this reason, thief such as desire are destroyed lockset, then can be drilled with screw on core 90 front end faces, and lock wherein with the instrument that tool is established thread head, firmly hale core 90 again and promptly can spur the collars 80 by clip projection 93, make the protuberance 84 of the collar 80 break away from the core draw-in groove 71 of rotating shaft 70,72 and destroyed, therefore,, its design can consider a left side though going up, the dextrorotation door turn to problem, yet, the stretching resistance intensity of the collar 80 may be dragged out away from the shortcoming of rotating shaft 70 in destroying by force, the necessity that is improved is then obviously arranged.

In view of this, the purpose of this utility model provides a kind of handle type lockset with improvement rotating shaft collar, it is that pothook clip with the collar is in the hook groove of rotating shaft, what make the collar axially has supporting of the tension intensity of pulling, and formed locating slot can form clip with the formed protuberance of the open-work root edge of handle in the clip flange of the collar.

The purpose of this utility model is achieved in that a kind of handle type lockset with improvement rotating shaft collar comprises handle, be positioned at the interchangeable core of handle, the rotating shaft that handle nose bar portion is connected, and the collar that is positioned at the rotating shaft front end, the body of its shaft forms towards the handle direction, under the core draw-in groove, and the open-work of splay configuration is set on the shell ends panel of handle, and the core of splay configuration is by inserting in this open-work in the body ring of the collar, it is characterized in that: in the rotating shaft, on the following core draw-in groove front end, following place is provided with bevelled edge respectively, and relative hook groove is set respectively on the end limit of two core draw-in grooves; The body front end of the collar forms projecting ring section, and the less clip flange in footpath that goes too far is extended at this projecting ring section root edge place forward, and the body bottom of this collar is extended extension board backwards again, and the terminal both sides of this extension board form the outer pothook of opening.

The clip flange middle section of the described collar is provided with locating slot, and the open-work root edge of the end plates of handle forms protuberance.

Owing to adopt such scheme: the intensity of pulling of supporting that axially has tension of the collar, and have left and right commutation of revolving door, and guarantee the steadiness of the collar.

Below in conjunction with drawings and Examples the utility model is further specified.
