The multifunctional door lock structure has the advantages of having an anti-insertion function, an escape function, a channel switching function and the function that a lock end can unlock the latch bolt, wherein in a door locking state, a door frame enables the prying-resistant bolt to be retracted inward, the anti-insertion spring is used for enabling the anti-insertion plate to pop up toward the direction of the latch bolt assembly, and the latch bolt assembly can not be pressed downward, so that the anti-insertion and anti-theft functions are achieved.

Description

A kind of multi-function door lock construction
Technical field
The utility model relates to lockset kind, relates in particular to a kind of multi-function door lock construction.
Background technology
The classification of door lock is a lot, each occasion to door lock require differently, average family is generally used safe-guard door lock, and is safe and price is more cheap; Can use coded lock, Fingerprint Lock at some high-end places, privacy mechanism, safety is very high, expensive.Door lock must have safety, stability as the safety precaution product; Safety can be weighed from two aspects: the one, resist the violence damage such as intentional destruction, mischief and premeditated sled, brill, in this regard, the mechanical strength of mechanical lock and electronic lock generally can both reach requirement at present, and in all kinds of door locks, only having electronic lock of radio frequency card is full-closed structure; The 2nd, precautionary technology is opened, and the poor ability of the anti-technical opening of mechanical lock is no matter the mechanical lock of which kind of structure all can be opened by other means; As door lock, its stability is extremely important equally, and this does not close door at closing time may bring heavy losses to financial company.For the analysis of above existing door latch structure, in like product, to limit because of structure at present to lack anti-plug function and escaping function, this can cause fatal loss and serious threat personal safety when special event occurs.Therefore, for above aspect, need to reasonably improve prior art.
The utility model content
For above defective, the multi-function door lock construction that the utility model provides a kind of and has anti-plug function, can reach emergency life escaping function, can realize Channel-shifted, tapered end can be opened the latch bolt function is to solve the many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of multi-function door lock construction, comprise cover plate, anti-plug module, bottom deck assembly, described anti-plug module is comprised of latch bolt assembly, anti-plate, anti-plug spring, pick-proof tongue and slide plate, this latch bolt assembly below connects inserts the anti-plate with the anti-plug spring in a pick-proof tongue and this pick-proof hypogloeeis end jack, simultaneously, described anti-plate end cover has a column turning set;
Pulling part is installed in slide plate upper end wherein and this pulling part connects a sliding block spring, back-moving spring of the outside connection of anti-plate turning set wherein; The bottom deck assembly inner surface that is positioned at the slide plate below is installed slow-witted tongue assembly, pulling part assembly and this pulling part assembly lower end are housed with clutch block in the installing hole of described cover plate and bottom deck assembly, this pulling part assembly is fixedly connected with the plectrum assembly, described pulling part assembly arranged on left and right sides dispose respectively one set aside the peach assembly, on dial the peach assembly; In addition, described bottom deck assembly inner surface is installed a slice side's tongue shifting block.
Described latch bolt assembly and slide plate be corresponding being installed on bottom deck assembly inner surface upside, the lower right double-screw bolt respectively; Follow closely with push jack described plectrum assembly lower end, and described bottom deck assembly side is fixedly connected with the liner plate assembly.
The beneficial effect of multi-function door lock construction described in the utility model is:
⑴ have anti-plug function: when locking a door state, doorframe is inwardly retracted the pick-proof tongue, utilizes the anti-plug spring that anti-plate is ejected toward latch bolt assembly direction, the latch bolt assembly can't past be pressed down, thereby play the anti-plug anti-theft feature;
⑵ have escaping function: 1. for outdoors: when on the door lock, clutch block breaks away from and ejects, and handle can only dally outdoors, can not drive other accessory; 2. in the door: drive the pulling part assembly by handle in the lower pressure gate, anti-plate is rotated, regain inward, can regain the latch bolt assembly simultaneously, drive the pulling part assembly by handle in the lower pressure gate, slide plate is deviate from from slow-witted tongue assembly screens, then the pulling part assembly side of drive tongue shifting block rotates, slow-witted tongue assembly is down regained, by these escape principles, can be reached the function of the escape of promptly opening the door;
⑶ have the Channel-shifted function: when slow-witted tongue group is regained, clutch block withdrawals of closing inward, on dial the peach assembly, set aside the peach assembly and can drive the pulling part assembly by clutch block the latch bolt assembly is regained, thereby reach the purpose that the front and back handle can both open the door;
⑷ have tapered end can open the latch bolt function: when slow-witted tongue assembly was regained, door lock core rotated the plectrum assembly, and the latch bolt assembly is regained, and door is opened.
