Description

A kind of safe-guard door lock

Technical field

The present invention relates to a kind of door lock, and in particular to a kind of safe-guard door lock.

Background technology

Each lock constructively has difference, and this just determines the difference of its function, in order to which public security needs, typically Lock either Nei Kai or external-open all relatively time-consuming, and it is certain external to need some to bear in some special occasions The extruding of active force, again can be from the door lock of inside and outside convenient enabling, and therefore, Tiandi lock just arises at the historic moment.

World door lock is mainly made up of three kinds of upper, middle and lower lock body and push rod and connecting rod, be divided into press-down type Tiandi lock and Flat push type Tiandi lock, at present, Tiandi lock can be used as the fire exit door escape lock such as market, supermarket, theater, auditorium, but the existing world Door latch structure is complex, especially transmission mechanism parts are more, and requires the smooth gapless of door body, therefore, existing Not only manufacturing cost is high for world door lock, and operation inconvenience is unable to water-proof anti-theft in particular circumstances.

In summary, it is necessary to which a kind of door lock of waterproof antirust pick-proof simple in construction is provided.

The content of the invention

In order to solve the problem of Tiandi lock is complicated, cost is high, the invention provides a kind of door lock simple in construction, tool There is waterproof antirust tamper-resistant function.

Technical scheme：A kind of safe-guard door lock, including guard member and door latch structure, wherein, the door latch structure Including fixed bottom surface, lock shaft, hinge and lock ring, fixing hole and lock ring are provided with the fixed bottom surface, the lock shaft is worn Cross fixing hole and enter guard member, the hinge is set in lock shaft, and with lock ring snap lock, the guard member and door latch structure are big Structure is surrounded, the door latch structure is connected with guard member by lock shaft and realizes lock function.

Further, needed for the guard member and door latch structure inner rivet are fixed at combination lock.

Further, the lock shaft can be around own axis.

Further, the material of the guard member and door latch structure is 304 stainless steels.

The present invention has the advantages that compared with prior art：The present invention provides a kind of antitheft, waterproof lockset, uses 304 stainless steels are raw material, and waterproof antirust pick-proof is designed as surrounding structure greatly, main part is two parts, and left side body is guard member, Right member main body is door latch structure, and the lock shaft of main part is connected into guard member through the hole at top, and lock shaft Front-end Design has One male means, after lock shaft penetrates left side guard member corresponding hole, rotates down lock shaft, realizes lock function, then Locked in right side body protection with conventional padlock.The present invention is fixed on casing junction using inner rivet, and outside be can't see Any fixed part, so that anti-theft and waterproof anti-theft function is played, novel in design, practical function, valency is than high, practicality By force, it is with low cost, be easy to batch micro operations production, therefore with very good popularization and application basis, masses are met well The need for.

Brief description of the drawings

Fig. 1 is the structural representation of the present invention；

Wherein, fixed bottom surface 1, lock shaft 2, hinge 3, lock ring 4, fixing hole 5, enter guard member 6.

Embodiment

In order that those skilled in the art more fully understand the objects, technical solutions and advantages of the present invention, with reference to saying The present invention will be described in further detail for bright book accompanying drawing.It should be appreciated that specific embodiment described herein is only to solve The present invention is released, is not intended to limit the present invention.
