Embodiment:

As shown in Figure 1, 2, the pilot pin of the utility model door, window (lock) structure-improved mainly comprises a pedestal 20, and a through hole is arranged on pedestal 20, and the outer peritreme of this through hole forms side-looking and is

Shape hole 23, and the opposite side nose end forms the circular port 24 with big external diameter,

Shape hole 23 endoporus rims have internal face 233 (as shown in Figure 6); A positioning rod 30, its front end is spheroid 32, the rear of spheroid 32 forms a torus 34, the rear of torus 34 be provided with Shape hole 23 is identical shaped

Shape block holder 35, the rear of block holder 35 is round bar body 38, and the end of round bar body 38 has screw thread 381, the cylinder 39 of the big external diameter that can be spirally connected, wherein block holder 35, round bar body 38 and cylinder 39 can penetrate In shape hole 23 and the circular port 24; One spring 40 is to be socketed on the round bar body 38, and its an end roof pressure exists On the internal face 233 in shape hole 23, and other end roof pressure makes backstay 30 form a rubber-like fastener (as shown in Figure 6) on the internal face 391 of cylinder 39.With regard to the said structure feature, wherein Shape block holder 35 forms clip location division 382 with the boundary of the round bar body 38 of less external diameter, and this clip location division 382 can select clip to be positioned at On the outer peritreme wall in shape hole 23 (as shown in Figure 4).In addition, pedestal 20 is can fix (or pre-buried) in door, window 10 (or doorframe 12), and wherein cylinder 39 can be selected to penetrate doorframe 12 (or door, window 10) and goes up in the default locating hole 52 (shown in Fig. 5,6,9,10).

Said structure is specifically implemented shown in Fig. 1,3,5,6, pedestal 20 of the present utility model is fixed on the side fixed frame 12 of door, window 10 or door, window by means of bolt 15, as pedestal 20 is when being fixed on door, the window 10, then with pedestal 20 corresponding doorframes 12 on, be provided with the jack base 50 that has locating hole 52 in the middle of; When door or window 10 will fix (lock) with doorframe 12, then with finger to the 32 operation turns of bad body, rotate an angle, when clip location division 382 exists When shape hole 23 outer peritreme walls were done the turn of contact, bilateral arcwall face 351 correspondences of block holder 35 entered The bilateral arcwall face 231 in shape hole 23, upper and lower planar portions 352 correspondences of block holder 35 enter During the upper and lower planar portions 232 in shape hole 23, because the elastic reset effect of spring 40, block holder 35 promptly enters

Shown in (as Fig. 4 B), at this moment, cylinder 39 is run out of outside the circular port 24 in 23 inside, shape hole, penetrates just in the locating hole 52 of jack base 50 shown in (as Fig. 5,6), just can reach door or window 10 are fixed on the doorframe 12.

By Fig. 3,4A as can be known, in the time door or window 10 will being separated with doorframe 12, then with finger spheroid 32 is pulled outwardly, and rotates an angle (about 90 degree), then bilateral arcwall face 351 clips of block holder 35 are positioned at In the shape hole 23, the rim of its upper and lower planar portions 232, then the cylinder 39 of backstay 30 promptly collapses in the circular port 24, will not run out of outside the circular port 24, and this moment, spring 40 was contraction-like, because the effect of spring 40, even block holder 35, clip is positioned at The peritreme in shape hole 23 will not dystopy.So door or window 10 can be opened and separate (shown in Fig. 5,6 dotted lines) with doorframe 12.

Another embodiment of the utility model is shown in Fig. 7,8,9,10, it mainly is to be designed to pedestal 20 cylindric, do not need the bolt hole seat, this pedestal 20 can be embedded on door, the window 10 (or doorframe 12), also be provided with locating hole 52 in doorframe 12 positions of pedestal 20 relatively, this locating hole 52 can be directly on doorframe 12, directly boring cooperates the jack base 50 of sheet, promptly can this locating hole 52 do the action of grafting with the cylinder 39 in the pedestal 20, fixing or be separated in the action of locating hole 52 with the cylinder 39 on the pedestal 20.
