The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Embodiment mono-:
As shown in Fig. 1~5, in the present embodiment, a kind of door lock described in the utility model, comprise the first lock piece 10 and the second lock piece 11 that cooperatively interact, in the present embodiment, the first lock piece 10 is arranged on a body, it can together rotate with door body, the second lock piece 11 is arranged on position corresponding with the first lock piece 10 on doorframe, wherein the second lock piece 11 is arranged on doorframe by rotating shaft 12 is rotating, the second lock piece 11 tools have to realize described the first lock piece 10 are entered line-locked primary importance and removes the second place to the first lock piece 10 lockings in its slewing area, the first lock piece 10 coordinates with the second lock piece 11, when primary importance, the second lock piece 11 is by the first lock piece 10 lockings, when the second lock piece 11 the first lock piece 10 shift-in freely during in the second place, shift out lock body.
The rotation of the second lock piece 11 is promoted by the first lock piece 10, concrete, the second lock piece 11 has and drives at closing time the second lock piece 11 to turn around the shaft 12 moving touch poles 13 and the check lock lever 14 to the first lock piece 10 lockings when primary importance, on the second lock piece 11 between check lock lever 14 and touch pole 13, be provided with an end opening and with the suitable groove of the first lock piece 10 shapes, check lock lever 14 also has the function that drives the second lock piece 11 to rotate when opening the door simultaneously, and touch pole 13 is structure as a whole with check lock lever 14.
The first lock piece 10 comprises a gate stop 15 and connects gate stop 15 and the connecting rod 16 of door body, connecting rod 16 is warp architecture, its crooked radian is consistent with the movement locus of gate stop 15, connecting rod 16 one end are fixedly mounted on a body, gate stop 15 and the perpendicular setting of connecting rod 16, one end of gate stop 15 is fixedly connected with the other end with connecting rod 16 be free end.Gate stop 15 and the second lock piece 11 upper grooves are suitable, and at door lock, regularly gate stop 15 is in groove, and the motion that limits gate stop 15 in the direction of motion of check lock lever 14 gate stop 15 when opening the door realizes locking.
On gate stop 15 and touch pole 13 and be positioned at the position that both contact and be provided with chamfering 17.Check lock lever 14 is provided with chamfering 17 away from the end of rotating shaft 12 side being positioned near touch pole 13.
The locking process of door is: promote door body and rotate around jointed shaft, the first lock piece 10 is with Men Tiyi doorframe direction motion in the same way, after moving to certain position, first gate stop 15 contacts with touch pole 13, promoting touch pole 13 moves, touch pole 13 drives the second lock piece 11 12 to rotate around the shaft, check lock lever 14 is structure as a whole and together rotates with touch pole 13 with touch pole 13, after turning to primary importance, gate stop 15 is locked, the size of coupling mechanism force is determined by the size that limits the power of the second lock piece 11 rotations, in the present embodiment, coupling mechanism force is the frictional force between the second lock piece 11 and rotating shaft 12.
In the process of closing the door, because connecting rod 16 is warp architecture, and its crooked radian is identical with the running orbit of gate stop 15 in switch gate process.Therefore can guarantee that gate stop 15 is substantially vertical with the first lock piece direction of motion (direction shown in A in Fig. 2) with the common tangent 18 of touch pole 13 contact positions when gate stop 15 contacts with touch pole 13, angular range can be between 85-105 degree, be preferably 87-93 degree, therefore can produce the component of other direction hardly, gate stop 15 also can contact with check lock lever 14 hardly in the process of closing the door simultaneously, reduces the frictional dissipation that the surface of check lock lever 14 is caused.
The releasing process of door is: pull a body to carry out the motion of opposite direction when locking a door, the first lock piece 10 moves away from the direction of doorframe in the same way with Men Tiyi, gate stop 15 contacts with check lock lever 14 by check lock lever 14 and drives the second lock piece 11 12 to rotate around the shaft, when the second lock piece 11 turns to the second place, gate stop 15 can be skidded off by the second lock piece 11 internal freedoms, realizes release.
Because gate stop in the process of closing the door 15 does not contact with check lock lever 14, therefore can not cause friction to check lock lever 14 surfaces, therefore when opening the door, frictional force is constant, and the required opening force size of door capable of being opened also keeps constant, and the comfort level of opening the door is high.
Embodiment bis-:
The door latch structure of the present embodiment and embodiment mono-is basic identical, and its difference is mainly that the structure of the first lock piece is different.As shown in Figure 6, in the present embodiment, the first lock piece comprises two connecting rods that are parallel to each other, be respectively head rod 21 and the second connecting rod 22, at head rod 21, away from the end of door body, be connected respectively the two ends of gate stop 23 with the second connecting rod 22, make the first lock piece be on the whole " Jiong " type.On gate stop 23, be arranged with the sleeve pipe 24 that can rotate voluntarily with respect to gate stop.
In the present embodiment, the first lock piece is set to be " Jiong " type structure, makes gate stop two ends all be connected with connecting rod, guarantees the stability of gate stop 23 in the process of closing the door of opening the door, and makes it not yielding, and it is constant that the opening force of door keeps.Sleeve pipe 24 is set can change sliding friction originally into rolling friction in the process of switch gate, can significantly reduce frictional force the loss of lock piece is increased the service life.
The term " first " that this programme adopts, " second " etc. are just distinguished on describing, and there is no special implication.
What need statement is; the above-mentioned specific embodiment is only preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with easily expect or replacement, all should be encompassed in protection domain of the present utility model.
