Described rod member 9 is to be combined by first rod member 91 and second rod member 92, it is made up of a square bar 921 and a round bar 922 this second rod member 92 by class's bar, this first rod member 91 is a square tube, the centre has a hole 911, this first rod member 91 and second rod member 92 can be installed on inboard door leaf and outside door leaf respectively, first rod member 91 is inserted in second cam 62 and breast wheel 63, second rod member 92 is inserted in first cam 61, and the rod member surface in first rod member 91 and second rod member 92 has a projection 914 respectively, 924 to provide the location of rod member, installation member is when door leaf, can be according to the actual requirements first rod member 91 and second rod member 92 be done and exchange installation, then can be applicable to L.H.flapped door or R.H.flapped door respectively.

When entire combination, as Fig. 2, shown in Figure 3, if stir the function that first rod member, 91 interlocks, second cam 62 promptly has automatic unlocking (following lock bolt 7 get back to the second place by primary importance) with the handling device (not shown) in the door leaf inboard; When promptly lock bolt 7 is the primary importance of stretching out outside casing 1 instantly (lock is blocking), this at present the stop part 72 of lock bolt 7 be subjected to the bias voltage of a flexible member 5, produce one and remove the restoring force of receipts to casing 1 inside, but because of the retainer 34 engagements effect of the locking groove 73 of lock bolt 7 down that is subjected to setting element 3, and will descend lock bolt 7 to be positioned primary importance, operate internal handle device (not shown) this moment, rotate second cam 62 by first rod member 91, as shown in Figure 3, make the clicking section 623 of second cam 62 stir the drive division 22 of lock bolt 2, make lock bolt 2 remove the time receiving (door opening state) to casing 1 inside, the first 632 of the breast wheel 63 of this first thrust unit 6 can spur the wing 31 of these setting elements 3 at this moment, and make setting element 3 produce length travel, this moment, the retainer 34 of this setting element 3 separated with locking groove 73 generations of following lock bolt 7, and then the stop part 72 that makes down lock bolt 7 is subjected to the bias voltage of flexible member 5 and produces transverse shift and get back to the second place, to reach the function of lock bolt 7 automatic unlockings down.

When with second thrust unit 8 (similar items such as lock group or key) when unblanking, as Fig. 4, shown in Figure 5, promptly descend lock bolt 7 to be the primary importance (lock is blocking) of partly stretching out at casing 1, rotate the impeller 81 of second thrust unit 8 this moment, the impeller 81 of this second thrust unit 8 can be stirred down the tooth 71 of lock bolt 7, make down lock bolt 7 get back to the second place by horizontal primary importance, when lock bolt 7 is positioned at the second place instantly, this moment is if rotate the impeller 81 of this second thrust unit 8 again, this impeller 81 can promote the plane 102 of trace 10, produce leverage by trace 10, and the hook 101 of this trace 10 meshes the recess 23 of lock bolt 2 on this, make these trace 10 meeting pullings go up lock bolt 2 and remove receipts to casing 1 inside, to reach the effect of opening door leaf with the biasing force of offsetting spring 21.

When being positioned at blocking, baffle plate 4 is positioned at second jiao of position, when lock is desired to reach the function of automatic unlocking, as described in Figure 6, when promptly lock bolt 7 is the primary importance of stretching out outside casing 1 instantly (lock is blocking), and baffle plate 4 is when being positioned at second jiao of position, this at present the stop part 72 of lock bolt 7 be subjected to the bias voltage of a flexible member 5, produce one and remove the restoring force of receipts to casing 1 inside, but because of the retainer 34 engagements effect of the locking groove 73 of lock bolt 7 down that is subjected to setting element 3, and will descend lock bolt 7 to be positioned primary importance, this moment operating handle device (not shown), this first rod member 91 rotates the breast wheel 63 of first thrust unit 8, second part 633 of this breast wheel 63 can promote second part 43 of these baffle plates 4, make the baffle plate 4 that is subjected to spring 35 bias voltages get back to first jiao of position by second jiao of position, promptly first of this baffle plate 4 part 42 can be away from the bearing surface 32 of setting element 3, rotate second cam 62 by first rod member 91 simultaneously, the clicking section 623 of this second cam 62 and stir the drive division 22 of lock bolt 2, make lock bolt 2 remove the time receiving (door opening state) to casing 1 inside, first of the breast wheel 63 of this first thrust unit 6 partly 632 can spur the wing 31 of these setting elements 3 and make setting element 3 produce length travels at this moment, this moment, locking groove 73 generations of retainer 34 and following lock bolt 7 of this setting element 3 separated, and then made down lock bolt 7 be subjected to the bias voltage of flexible member 5 and produce transverse shift and get back to primary importance.

The utility model is used in door-plate when left and right door leaf is installed, as shown in Figure 7, no matter its installation exercise is left-handed door or dextrorotation door, all can directly select the right position and the directly directed installation of do, it only will unload the handle assembling and dismantling first rod member 91 and second rod member 92 are done exchange, reconfigures installation again; Promptly change to first rod member, 91 plant first cam 61, second rod member, 92 plant breast wheels 63 and second cams 62 by original first rod member, 91 plants, second cam 62 and breast wheel 63, second rod member, 92 plants, first cam 61, because first rod member 91 and second rod member 92 are respectively equipped with a projection 914,924 so that location usefulness to be provided in the surface of rod member, it is no matter for the mfg. moulding die or the assembling process of simplification factory and save manufacturing cost or provide the convenience of user's installation exercise to be all existing product can't be obtained during plant.

The utility model is because the left side that changes the outfit, during the dextrorotation door, when first rod member 91 and second rod member 92 are substituted, may cause the rotation of breast wheel 63 or move and the hole 612 of causing first cam 61, the hole 622 of second cam 62 can't align to cause in line with the hole 631 of breast wheel 63 installs difficulty, for solving this problem, the utility model further has two positioners in first cam 61 with breast wheel 63 places as shown in Figure 8, this positioner is by a steel ball 635, one spring 636, one plunger 637, and these first cam, 61 surfaces have two depressions 615,615; These breast wheel 63 surfaces have two bellmouths 634, when installing, steel ball 635, spring 636 are positioned in the bellmouth 634 of breast wheel 63, clog bellmouth 634 with plunger 637 again, make steel ball 635 outstanding breast wheel 63 surfaces and with depression 615 engagements of first cam 61, promptly produce locating effect, make change the outfit first rod member 91 and second rod member 92, breast wheel 63 does not rotate and displacement, and it is identical that this positioner also can be installed between breast wheel 63 and second cam 62 its locating effect.

Preferred embodiment of the present utility model is modified as a key or its similar item with the impeller of wherein said lock group and lock group; And setting element is modified as a plurality of screenings, also can reach the purpose of this utility model.

But all embodiment of above-mentioned the utility model only are preferable possible embodiments of the present utility model, and non-is in order to limit enforcement of the present utility model.
