Abstract
A door lock structure comprises a lock cover, an inclined tongue, a first elastic member, a rotary knob, a second elastic member, a transmission block, a pulling block, a stagnating tongue and a locking block. The lock cover comprises a base plate and a side plate, and the inclined tongue and the stagnating tongue penetrate through the side plate. The rotary knob, the transmission block, the pulling block and the locking block are all connected with the base plate in a rotating mode. The rotary knob is provided with a first door opening arm and a second door opening arm, and the first door opening arm and the second door opening arm are connected with the inclined tongue and the transmission block in an abutting mode respectively. The two ends of the pulling block are connected with the transmission block and the stagnating tongue in an abutting mode respectively. The stagnating tongue comprises a locking pin, a press plate connected with the locking pin in a sliding mode and a third elastic member, wherein a groove is formed in the locking pin, a lug is arranged on the press plate, the third elastic member is contained in the groove, the two ends of the third elastic member are connected with the lug and the groove in an abutting mode respectively, and a protruding pillar on the locking block is connected with the transmission block and the press plate in an abutting mode. The locking block is rotated to enable the stagnating tongue to stretch out of the side plate, due to the fact that the protruding pillar is connected with the press plate in the mutual abutting mode, the press plate forces the protruding pillar to rotate towards the side far away from the stagnating tongue under the effect of the third elastic member, the fact that the protruding pillar is directly connected with the stagnating tongue in an abutting mode is avoided, smoothness of door opening is ensured, and the door lock structure is prevented from being damaged.

The specific embodiment
For the ease of understanding the utility model, the below is described more fully the utility model with reference to relevant drawings.Provided preferred embodiment of the present utility model in accompanying drawing.But the utility model can be realized in many different forms, is not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present utility model more comprehensively thorough.
Please consult simultaneously Fig. 1 and Fig. 2, it is respectively the structural representation after the structural representation of door latch structure 10 of an embodiment and door latch structure 10 are removed pressing plates.Door latch structure 10 comprises: locking closure 100, latch bolt 200, the first elastic component 300, knob 400, the second elastic component 500, drive block 600, shifting block 700, slow-witted tongue 800 and lock dog 900.
Latch bolt 200 and slow-witted tongue 800 pass side plate 120 and arrange.
The first elastic component 300 be located on substrate 110 and with latch bolt 200 1 end butts.The first elastic component 300 is used for providing elastic-restoring force in latch bolt 200.In the present embodiment, the first elastic component 300 is torsion spring.
Knob 400 is rotationally connected with substrate 110, and the second elastic component 500 is located on substrate 110 and with knob 400 and is connected.The second elastic component 500 is used for providing elastic-restoring force in knob 400.In the present embodiment, the second elastic component 500 is torsion spring.
Knob 400 is provided with first arm 410 and second the open the door end butt of arm 410 and latch bolt 200 of arm 420, the first that opens the door that opens the door.Drive first arm 410 rotations of opening the door when knob 400 rotates, first arm 410 that opens the door drives latch bolts 200 and shrinks toward side plate 120 1 sides.
Shifting block 700 is rotationally connected with substrate 110, shifting block 700 1 ends and drive block 600 butts, the other end and slow-witted tongue 800 butts.Drive block 600 rotates and drives shifting block 700 rotations, and it is flexible that shifting block 700 drives slow-witted tongues 800.
Slow-witted tongue 800 comprises lock pin 810, pressing plate 820 and the 3rd elastic component 830.
Lock pin 810 passes side plate 120 and arranges, and offers groove 812 on lock pin 810.
See also Fig. 3, it is the structural representation of pressing plate 820.Pressing plate 820 is slidably connected with lock pin 810, and the glide direction of pressing plate 820 is vertical with lock pin 810 glide directions, and pressing plate 820 is provided with projection 821.
In the present embodiment, lock pin 810 is provided with guide post 814, offers the bar shaped bullport 823 vertical with lock pin 810 glide directions that is socketed on guide post 814 on pressing plate 820, and guide post 814 coordinates with bullport 823 to be realized being slidably connected.
The 3rd elastic component 830 is contained in groove 812, its two ends respectively with the side arm butt of projection 821 and groove 812.The 3rd elastic component 830 is used for providing the active force that makes pressing plate 820 glide directions.In the present embodiment, the 3rd elastic component 830 is spring.
The operating principle of door latch structure 10 is as follows:
In the time of need to opening the door fast, by the handle rotating knob 400 that is connected with knob 400, first opens the door arm 410 drive latch bolts 200 toward the interior contraction of side plate 120, simultaneously second arm 420 that opens the door drives drive blocks 600 and rotates, drive block 600 drives shifting block 700 and rotates, and shifting block 700 drives slow-witted tongue 800 toward the interior contraction of side plate 120.As seen, as long as turning knob 400, latch bolt 200 is shunk toward side plate 120 simultaneously with slow-witted tongue 800, has realized opening the door fast, the present unlocking condition of door latch structure that is shown in Figure 4, and this moment, latch bolt 200 was in contraction state simultaneously with slow-witted tongue 800.
Rotating lock dog 900, make slow-witted tongue 800 stretch out side plate 120 when outer, due to projection 910 and the mutual butt of pressing plate 820, the resilient force that pressing plate 820 is provided by the 3rd elastic component 830, pressing plate 820 acts on active force on projection 910, makes projection 910 toward rotating away from slow-witted tongue 800 1 sides, avoids projection 910 and the direct butt of slow-witted tongue 800, guarantee that the fast open gate open is freely without hindrance, make door latch structure 10 avoid damaging.
When needing the slow-witted tongue 800 of manual unlocking, rotate lock dog 900, it is past away from lock dog 900 1 Slideslips that projection 910 on lock dog 900 promotes pressing plate 820, the 3rd elastic component 830 compressions, make projection 910 and drive block 600 butts, be rotated further lock dog 900 and drive drive block 600 rotations, drive block 600 drives shifting blocks 700 and rotates, shifting block 700 drives slow-witted tongues 800 and shrinks toward side plate 120 1 sides, realizes that manual unlocking stays tongue 800.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
