The specific embodiment

Please refer to Fig. 1, on a pair of, lower locking plate 1,18 form male and female each other cooperates, also be front end or claim the first half one to be concaved with to be used for holding jointly dead bolt 7 at their aspectant ends, lock hook 13, the lock tongue cavity 26 of 36 leading section, lock hook chamber 28 and be used for holding jointly whole lock dog 20, the lock dog chamber 17 of lock core 23, lock core cavity 40, and on edge, chamber, be formed with a pair of retaining prominent 29 corresponding to a pair of lock hook chamber 28, last, lower locking plate 1,18 the other end also is that the both sides one extension of end, rear end constitutes a pair of fork pin 4,9, thus make a pair of on, lower locking plate 1,18 form one on the whole

Shape.Wherein, a pair of fork pin 4 is being formed with a disappearance part on a side side of a pair of fork pin 9, by read disappearance part constitute lock hook chamber 5,5 ', this holds to go into for a pair of lock hook 13,36 to lock hook chamber 5,5 ' be used for, and does not show in order to the lock hook 13,36 between a pair of fork pin 4,9 and is obstructed and can be free movable.The leading section of a pair of lock hook 13,36 respectively by lock hook axle 16,33 through screw 30 and hub setting on lower locking plate 18, and be accommodated in by in 1,18 lock hook chambeies 28 that form jointly of upper and lower jam plate, the middle part of a pair of lock hook 13,36 is corresponding between a pair of fork pin 4,9, promptly be contained in movably in the described lock hook chamber 5, the rearward end of a pair of lock hook 13,36 respectively be formed with pitch pin chamber 12 bending towards each other a pair of collude pawl 6,6 ', a pair of like this lock hook 13,36 forms between upper and lower jam plate 1,18 and exactly likes chela.Collude pawl 6,6 ' on to set firmly material can be to mould to tremble, also can be rubber, can also be the pawl of nylon etc. collude cover 8,8 ', this colludes cover 8,8 ' can be avoided lock hook 13,36 to pawl, and it colludes that pawl 6,6 ' with the vehicle steel ring takes place to rub and the situation that undermines vehicle when the On/Off.The leading section of dead bolt 7 places lock tongue cavity 26 slidably, and offer an elongated slot in the central authorities of this leading section, this elongated slot promptly constitutes spring groove 34, the groove content is gone into spring 35, one of spring 35 end is kept out on the bottom land wall of spring groove 34, the other end then is supported on corresponding spring groove groove 34 and extends on the stop screw 25 in spring groove 34, stop screw 25 is installed on the lower locking plate 18, like this, spring 35 just maintains certain predetermincd tension, and this predetermincd tension can also be regulated by the trimming screw on screw 32 31.Dead bolt 7 has been recessed to form meniscate cavity 11,38 in the both sides that are arranged in lock tongue cavity 26, should to meniscate cavity 11,38 respectively with form in a pair of lock hook 13,36 on flange 24,24 ' match, because this cooperation is similar to cooperating of bulb and ball bowl-type formula, therefore all cooperations with other similar type of being easy to know by inference also will be understood that within technical solutions of the utility model, for example with the position of described cavity 11,38 and flange 24,24 ' the position exchange also and be fine.Side is formed with a lock dog groove 14 near cavity 11 places one of at the position of lock tongue cavity 28 that dead bolt 7 is arranged in.The part that the rearward end of dead bolt 7 promptly stretches outside lock tongue cavity 26 is entreated among pitching pin chamber 12.Lock dog 20 carries spring 19 and is installed with in lock dog chamber 17, and the one end bearing is on spring 19, and the other end is then joined with lock dog groove 14 door bolts.Being installed with the lock core shaft 22 of the lock core 23 in lock dog chamber 40 matches with lock core axial trough 21 on the lock dog 20.

By above-mentioned will be of the present utility model each about parts after setting completed, through screw 41 upper and lower jam plate 1,18 is closed admittedly through screw 3,15 and by screw 10 by screw 2.

Please refer to Fig. 2, Fig. 3, the applicant will specifically tell about action of the present utility model and service condition in conjunction with this two width of cloth accompanying drawing.When inserting lock core 23 and cw turn key 42 with key 42, because the lock core shaft 22 of lock core 23 is in the lock core axial trough 21 that is plugged on the lock dog 20, therefore, at lock core 23 in right handed process, just driving lock dog 20 by lock core shaft 22 moves to right, overcome at lock dog 20 under the elastic force effect of spring 19, make in the lock dog groove 14 of lock dog 20 on dead bolt 7, dead bolt 7 is carried out release.At this moment, dead bolt 7 is under the restoring force effect of spring 35, stretch to fork pin chamber 12, in this process, drive a pair of lock hook 13,36, that end that makes the front end of lock hook 13,36 promptly be positioned at lock hook chamber 28 is done inwardly to draw in opposite directions, and the end is promptly done the action of outwards dehiscing respectively corresponding to that end in lock hook chamber 5 after a pair of lock hook 13,36, make a pair of pawl 6,6 ' the become open state of colluding, be state shown in Figure 2, thereby get so that the vehicle tyre 44 that pool is put on parking frame 43 is recessed fork pin chamber 12.And when the people comes to park, as soon as vehicle tyre 44 enters fork pin chamber 12, the personnel that keep an eye in place of parking pinch as long as the afterbody of dead bolt 7 gently added to push away, make dead bolt 7 overcome the elastic force of spring 35 and slightly contract to lock tongue cavity 26, in this process, the lock dog 20 that before had been disengaged position just enters in the lock dog groove 14, and a pair of lock hook 13,36 just presents and aforementioned opposite state, promptly present state shown in Figure 3, with Vehicle locking on parking frame 43.Because the key 42 of this lock is the personal management of keeping an eye on by the place of parking, therefore for the person of parking, need only to pay and park, adopting when getting vehicle checks the number opens.And this texture ratio is more reasonable and firm, can prevent from fully effectively to have things stolen.
