Specific embodiment

Referring to Fig. 3 to Figure 10, it is automatic in control latch lock, including be set on gate 1 latch head 2, be fixedly installed on it is big Panel 3 on door 1, the panel 3 are fixedly connected with shell 4, the movement that spanner 5 is arranged, connect with latch head 2 in the shell 4 Pull rod 6, wherein moving pull rod 6 connects spanner 5, described 5 one end of spanner is flexibly connected block 51, and wherein block 51 is embedded in panel In 3, it is flexibly connected one end in the shell 4 and mobile pull rod 6 contradicts the cramp 7 limited, the cramp 7 is " J " font. The cramp 7 connects the first spring 8, wherein the first spring 8 is specially torsionspring, the mobile pull rod 6 connects tension spring 9, institute 9 one end of tension spring is stated to be fixedly connected with shell 4.Wherein gate 1 is corresponding closes in doorframe, and wherein latch head is convenient in setting in doorframe 2 stretch out the lockhole for carrying out padlock gate 1, and latch head 2 need to be shunk when needing to unlock, and are arranged with mobile pull rod 6 mutually Contradict the cramp 7 that is limited, 7 pairs of 6 defined positions of mobile pull rod of cramp achieve the effect that self-locking, prevent latch head 2 after enabling Stretching and ground face contact, avoid damage latch head, and secondly block 51 is movably set in the end of spanner 5 and is embedded in panel 3, Make not box out cave on panel 3, prevent dust, sundries from entering inside shell 4, avoids generating and 4 internal structure Caton of shell is asked Topic occurs.

The mobile pull rod 6 includes being connected with each other and the upper connecting rod 61, the lower pull rod 62 that are moved backward, upper connecting rod 61, Lower pull rod 62 is arranged in parallel, and the spanner 5 is mutually flexibly connected with lower pull rod 62, and the spanner 5 is movably set in shell 4 Interior, described 9 one end of tension spring is fixedly connected with lower pull rod 62, and specifically 9 one end of tension spring is fixedly connected on lower pull rod 62 and spanner 5 Active connection place, wherein through-hole 623 is arranged in lower pull rod 62, the setting of spanner 5 is flexibly connected the first cylinder with lower pull rod 62, In the first cylinder run through and be limited in through-hole 623, wherein corresponding with the first cylinder active path waist type groove is arranged in shell 4 44, the setting of upper connecting rod 61 mutually contradicts the resistance surface 611 limited with cramp 7.Wherein upper connecting rod 61 and lower pull rod 62 The folding condition of control latch head 2 is connect and carried out by moving up and down respectively with latch head 2, wherein block 51 and spanner 5 End is hinged, and axis body is fixedly installed in shell 4, and wherein spanner 5 is in nearly 51 end of block and axis body transition fit, make spanner 5 and Shell 4 is mutually flexibly connected.Axis body is arranged in shell 4 at cramp 7, and cramp 7 and axis body transition fit make it be movably connected on shell In body 4, the first spring 8 is set between cramp 7 and shell 4, and 8 one end of the first spring is fixedly connected on cramp 7 and connect with shell 4 Place, 8 other end of the first spring are set to 7 one end of cramp, provide the rotation of cramp 7 to the twisting resistance inconsistent with upper connecting rod 61.Button When piece 7 and resistance surface 611 mutually contradict, upper connecting rod 61 can not be displaced outwardly, thus achieve the purpose that locking, next first spring 8 make the rotation of spanner 5 restore to 623 lower end of through-hole to contradict.

Activity setting connection upper connecting rod 61 and lower pull rod 62 and the gear 41 being driven, the pull-up on the shell 4 The first groove 612 is arranged in 61 one end of bar, and the second groove 621 is arranged in described lower 62 one end of pull rod, and the gear 41 is set to first Between groove 612 and the second groove 621, wherein the first groove 612, the second groove 621 are engaged with gear 41.Reverse movement Upper connecting rod 61, lower pull rod 62 are driven by gear 41, and wherein resistance surface 611, resistance surface 611 and cramp is arranged in upper connecting rod 61 7 contradict and carry out limitation upper connecting rod 61 and lower pull rod 62 is mobile, achieve the effect that self-locking, and the structure is simple, and the kind of drive is easy.

The first slot 613 is arranged in the shell 4, and the second slot 622 is arranged in the lower pull rod 62, and the upper connecting rod 61 is fixed Corresponding with the first slot 613 first limited post 42 is set, is fixedly installed the second limited post 43 on the shell 4, described the One limited post 42 is set in the first slot 613, and second limited post 43 is set in the second slot 622.First limited post 42, the setting of the first slot 613 defines the movement routine of upper connecting rod 61, is movably set in shell 4 by this kind of mode It and move up and down it only can.The setting of second limited post 43, the second slot 622 defines the movement routine of lower pull rod 62, It is movably set in shell 4 by this kind of mode and move up and down it only can.

The spanner 5 connects second spring 52, and wherein 52 one end of second spring is fixedly connected with block 51.Block 51 is arranged Second spring 52 is released to the state for making it keep being in same level with panel 3 after the contact of block 51.

Wherein 7 one end of cramp and the upper end inner surface of block 51 mutually contradict, pressing 51 upper end of block make cramp 7 rotation from And cramp 7 is made to be detached from the contact to resistance surface 611, so that upper connecting rod 61 is in the state of unlock, tension spring 9 pulls lower pull rod 62 and leads to It crosses gear 41 and drives upper connecting rod 61, be displaced outwardly upper connecting rod 61, lower pull rod 62 can and tightening state and extensive is released to latch head 2 Multiple freely to flex outward, latch head 2 releases pulling force contraction state and can pop up to complete movement of locking a door.

When needing to keep tightening state to latch head 2,51 lower section of pressing block simultaneously makes spanner 5 by pushing 51 upper end of block It is rotated along it with 4 active connection place of shell, the rotation of spanner 5 drives lower pull rod 62 to rise while making upper connecting rod by the transmission of gear 41 61 declines be retracted in shell 4 while pulling latch head 2 to contract, when latch head 2 is retracted in gate, gate It opens, since the first spring 8 is arranged in cramp 7,7 upper end of cramp is made to keep being bonded with upper connecting rod 61, release the pushing to block 51 Afterwards, tension spring 9 makes lower pull rod 62 and upper connecting rod 61 have the tendency that being displaced outwardly, and the mutually conflict of cramp 7 and resistance surface 611 makes Pull rod 61, lower pull rod 62, which can not be displaced outwardly, be displaced outwardly latch head 2 can not to realize self-locking function.

In the present invention: setting mutually contradicts the cramp 7 limited, 7 pairs of cramp mobile pull rods with mobile pull rod 6 6 defined positions achieve the effect that it is self-locking, prevent open the door after latch head 2 stretch out with ground face contact, avoid damage latch head 2.Block 51 are movably set in the end of spanner 5 and are embedded in panel 3, make not box out cave on panel 3, prevent dust, sundries from entering shell Inside body 4, avoid the problem that generating to 4 internal structure Caton generation of shell.
