Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a full hook lock of sliding door, as shown in fig. 1-3, including a lock body 1 and a hook plate 2, wherein, the lock body 1 is installed in the sliding door, and the hook plate 2 is fixedly installed on the corresponding position of the door frame, when the sliding door is closed, the lock body 1 can be matched and connected with the hook plate 2, so as to realize the function of locking the sliding door. Specifically, be provided with mobilizable circular arc gib head 3 in the lock body 1, be provided with on the lock body 1 and stretch out hole 101 and stretch into hole 102, circular arc gib head 3 can stretch out from stretching out hole 101 and stretch into hole 102 and return to in the lock body 1, be provided with first connecting hole 201 and second connecting hole 202 on the hook plate 2, circular arc gib head 3 passes first connecting hole 201 and second connecting hole 202 in proper order when stretching out, therefore, when locking, circular arc gib head 3 can be complete pass whole hook plate 2, after connecting through this kind of mode, circular arc gib head 3 is connected with hook plate 2 completely, like this when transversely pulling or lifting to the door, circular arc gib head 3 homoenergetic be firm with hook plate 2 is connected, in order to keep the lockout state of door, the security is very high.
Further, a driving part 4 is arranged in the lock body 1, the driving part 4 comprises a driving gear 401, a transmission gear 402 and a driven gear 403, a driving hole 5 is formed in the middle of the driving gear 401, two ends of the driving hole are communicated with the outside of the lock body 1, the transmission gear 402 is respectively meshed with the driving gear 401 and the driven gear 403, the driven gear 403 is fixedly connected with the arc hook head 3, the driving hole 5 is specifically arranged into a square hole structure which is in plug-in fit with external transmission square steel (not shown in the figure), the transmission square steel is controlled by structures such as a knob or a handle on the inner side and the outer side of the sliding door, when a person rotates the knob or the handle, the transmission square steel is driven to rotate, the driving gear 401 is driven to rotate, the transmission gear and the driven gear are driven to rotate, and finally the arc hook head 3 extends out of the lock body or retracts into the lock body through the driven gear, and the extending and retracting correspond to locking and unlocking respectively.
