Description
Technical field
The present invention relates to Household door knob technical field, especially relate to a kind of door handle with secure latch function.
Background technology
Being designed with opal on the antitheft door of present many families, facilitate owner to observe situation outdoors, unexpectedly this but becomes the leak of thief's burglary.Thief utilizes opal to peep mirror and checks interior decoration and personnel's situation, then screw out opal insert instrument just can unlatching burglar-proof door.Can just can smooth opening antitheft door within the time less than two minutes it is to say, there is people to pass through opal.The door handle used on the market at present mostly is inside and outside each one, uses in pairs, and exterior door handle only rotates when lock is unlocked state could effectively open entering house door；Interior door handle is then configured to no matter door lock can be transferred through rotating by door unlatching under which kind of state, such design gate handle has two reasons: one be think indoor toward outward swinging door time be the open mode under one " safety " state, thieves etc. are generally in outer inlet chamber, do not have thief before this in indoor situation, for the form just can opened the door without first opening door lock when facilitating indoor occupant therefore be designed to outwards be opened by indoor by door handle.What is more, for the door lock with anti-theft protection or guard against theft and alarm system that some are comparatively senior, just " single step " can open gate without any unblock formality, and do not touch any antitheft or alarm device when being also designed to by interior unlatching outward.Two allow for conveniently, if will be also designed to as the form opened from outside to inside by the interior door lock opened outward, each user will pass through key etc. and first unlock, then opens the door, and so can significantly lose time, and can bring great inconvenience.Given this two reasons, and door lock is designed to above-mentioned unlatching form, this adds increased risk.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of door handle with secure latch function, be avoided that outside personnel just can open door lock by opal hole unlocking tool and carry out burglary.
nullFor reaching above-mentioned purpose，The technical scheme is that a kind of door handle with secure latch function，Including fixed disk、Axle sleeve、Spring and rotating shaft，Described axle sleeve includes the cap body linked into an integrated entity from top to bottom、Hollow pipe and location dish，The upper surface of described location dish is provided with two symmetrical rectangular ribs，The outer rim of described rib is beyond the outer rim of location dish，The second square groove it is provided with in described cap body，It is provided with rotating shaft in described axle sleeve，Described rotating shaft includes the circular shaft of centre and the square shaft of both sides，Wherein the square shaft of side is positioned at the second square groove and its top top lower than the second square groove，The square shaft of opposite side is through fixed disk and stretches in rotating disk，Described fixed disk includes the lower and upper disk being arranged concentrically，Described upper dish inner hollow and in set spring，The upper wall center of upper dish is provided with through hole，The connection of described upper through hole outer rim is provided with two symmetrical square openings.
Described center of turntable is provided with the first square groove.
The invention has the beneficial effects as follows: be stuck in square opening by rib so that rotating shaft and fixed disk are relatively fixed can not be freely rotatable, it is to avoid outside personnel just can open door lock by opal hole unlocking tool and carry out burglary.

Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, technical scheme is described in further detail.
As shown in Fig. 1～Fig. 9, a kind of door handle with secure latch function, including fixed disk 2, axle sleeve 3, spring 4 and rotating shaft 5, described axle sleeve 3 includes the cap body 32, hollow pipe 31 and the location dish 33 that link into an integrated entity from top to bottom, cap body 32, hollow pipe 31 are internal with location dish 33 to be connected, the upper surface of described location dish 33 is provided with two symmetrical rectangular ribs 34, and the outer rim of described rib 34 is beyond the outer rim of location dish 33.
The second square groove 35 it is provided with in described cap body 32, second square groove 35 can match grafting with square shaft 52, it is provided with rotating shaft 5 in described axle sleeve 3, described rotating shaft 5 includes the circular shaft 51 of centre and the square shaft 52 of both sides, wherein the square shaft 52 of side is positioned at the second square groove 35 and its top top lower than the second square groove 35, this setting makes axle sleeve 3 have the space that past fixed disk 2 direction is moved, the square shaft 52 of opposite side is through fixed disk 2 and stretches in rotating disk 1, and described rotating disk 1 center is provided with the first square groove 11.
Described fixed disk 2 includes the lower wall 21 and the upper dish 22 that are arranged concentrically, lower wall 21 is circumferentially with the screw hole 23 and oval hole 24 that are distributed between two, namely two screw holes 23 and two oval holes 24 are and are oppositely arranged, lower wall 21 center is additionally provided with the lower through-hole 25 for rotating shaft 5 traverse, lower wall 21 is fixed on door by squeezing into screw in screw hole 23, two oval holes 24 are to design to facilitate uniformly manufactured, also can play the effect of loss of weight simultaneously.
Described upper dish 22 inner hollow and in set spring 4, the upper wall center of upper dish 22 is provided with through hole 26, and upper through hole 26 is available for location dish 33 traverse, described upper through hole 26 outer rim connection be provided with two symmetrical square openings 27.
The operation principle of the present invention is: during original state, owing to the active force of spring 4 makes two ribs 34 of axle sleeve 3 be stuck in two square openings 27, and fixed disk 2 is fixed on door by its screw hole 23 offered above, so cannot rotary axle box 3, namely be relatively fixed can not be freely rotatable for rotating shaft 5 and fixed disk 2.When under holding cap body 32 and exerting oneself by axle sleeve 3, axle sleeve 3 overcomes the active force of spring 4 to move toward direction, fixed disk 2 place so that two ribs 34 depart from square opening 27, and such axle sleeve 3 just can be freely rotatable, rotated by axle sleeve 3 and drive rotating shaft 5 and rotating disk 1, thus can smoothly door be opened.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention.
