Description

Push button Anti-theft door handle

Technical field

The present invention relates to Household door knob technical fields, more particularly, to a kind of push button Anti-theft door handle.

Background technique

It is designed with opal on the security door of present many families, facilitates owner's observation situation outdoors, unexpectedly this but becomes small The loophole of burglary steathily.Thief peeps mirror using opal and checks interior decoration and personnel's situation, then screws out opal insertion tool It being capable of unlatching burglar-proof door.That is, someone being capable of smooth opening within the time less than two minutes by opal Security door.Current door handle used on the market is mostly each one inside and outside, use in pairs, and outdoor door handle only has when lock is opened Rotation could effectively open entering house door when opening state；And indoor door handle be then configured to no matter door lock under which kind of state all Rotation can be passed through by Men Kaiqi, there are two reasons for design door handle in this way: first is that thinking is a kind of " peace when indoor past outward swinging door Open mode under state entirely ", thief etc. be usually all it is outer enter the room, be not in thief before this indoors the case where, be Facilitate indoor occupant thus by door handle be designed to by it is indoor open outward when the form that can open the door without first opening door lock.More Have notably, for some more advanced door locks with anti-theft protection or anti-theft alarm system, is also designed to from interior toward external-open Gate is opened without any unlock formality energy " single step " when opening, without touching any antitheft or warning device.Second is that considering To convenience, if each user will pass through by the form that picture is opened from outside to inside is also designed to by the interior door lock opened outward Key etc. first unlocks, then opens the door, and can waste time significantly in this way, and can bring great inconvenience.Given this two reasons, And door lock is designed to above-mentioned unlatching form, this adds increased risks.

Summary of the invention

It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of push button with secure latch function is provided Anti-theft door handle is avoided that outside personnel can open door lock with unlocking tool by opal hole and carry out burglary.

In order to achieve the above objectives, the technical scheme is that push button Anti-theft door handle, including fixed disk, axle sleeve, hand Handle, shaft and spring, the axle sleeve include the cap body to link into an integrated entity from top to bottom, hollow tube and positioning disk, the positioning disk Upper surface set there are two symmetrical rectangular rib, the outer rim of the rib exceeds the outer rim of positioning disk, the axis Handle is plugged in set, cap body side lower end and the corresponding side upper end of hollow tube are equipped with the slot being inserted into for handle, the hand Handle includes the stock outside axle sleeve and the quarter butt inside axle sleeve, the length of the slot on the diameter and cap body of the stock Equal, the quarter butt end is equipped with the second square groove, and the fixed disk includes the lower and upper disk being arranged concentrically, the upper disk Inner hollow and it is interior set spring, the upper wall center of upper disk is equipped with upper through-hole, and the upper through-hole outer rim connection sets that there are two symmetrical point The square hole of cloth wears shaft in the axle sleeve, and the shaft includes the square shaft of intermediate circular shaft and two sides, wherein one The square shaft of side is located in the second square groove, and the square shaft of the other side passes through fixed disk and protrudes into turntable.

The stock and quarter butt are to be vertically arranged.

The hollow tube upper end is equipped with raised line, and the quarter butt outer wall is set there are two symmetrical groove, the groove and raised line It matches.

The beneficial effects of the present invention are: be stuck in square hole by rib so that shaft with fixed disk is relatively fixed cannot It is freely rotated, avoids outside personnel that from capable of opening door lock with unlocking tool by opal hole and carry out burglary.

Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

As shown in Fig. 1~Figure 11, push button Anti-theft door handle, including fixed disk 2, axle sleeve 3, handle 4, shaft 5 and spring 6, the axle sleeve 3 includes cap body 32, hollow tube 31 and the positioning disk 34 to link into an integrated entity from top to bottom, cap body 32, hollow tube 31 With positioning disk 34 be cylindrical and internal be connected to is protruded into for handle 4 and shaft 5, there are two the upper surface of the positioning disk 34 is set Symmetrical rectangular rib 35, the outer rim of the rib 35 exceed the outer rim of positioning disk 34.

Handle 4 is plugged in the axle sleeve 3, the 32 side lower end of cap body and the corresponding side upper end of hollow tube 31, which are equipped with, to be supplied The slot that handle 4 is inserted into, the handle 4 includes being located at the stock 41 outside axle sleeve 3 and the quarter butt 42 inside axle sleeve 3, described The diameter of stock 41 and the equal length of the slot in cap body 32, prevent handle 4 is from the left-right rotation in slot, 42 end of quarter butt Portion is equipped with the second square groove 43, and the second square groove 43 can match grafting, 31 upper end of hollow tube with square shaft 52 Equipped with raised line 33,42 outer wall of quarter butt is set there are two symmetrical groove 44, and the groove 44 and raised line 33 match, the setting So that having positioning action when the quarter butt 42 of handle 4 is inserted into, while guiding role is played to moving up and down for axle sleeve 3, the length Bar 41 and quarter butt 42 are to be vertically arranged, stock 41 facilitate people when opening the door with strength.

The fixed disk 2 includes the lower wall 21 and upper disk 22 being arranged concentrically, and is circumferentially with the spiral shell being distributed two-by-two on lower wall 21 Wire hole 23 and waist round hole 24, i.e. two screw holes 23 and two waist round hole 24 are to be oppositely arranged, and 21 center of lower wall is additionally provided with confession The lower through-hole 25 that shaft 5 passes through, lower wall 21 are fixed on door by squeezing into screw in screw hole 23, two waist round hole 24 be for Facilitate uniformly manufactured and design, while can also play the role of loss of weight.

22 inner hollow of upper disk and it is interior set spring 6, the upper wall center of upper disk 22 is equipped with upper through-hole 26, and upper through-hole 26 can It is passed through for positioning disk 34, upper 26 outer rim of the through-hole connection is set there are two symmetrical square hole 27, is worn in the axle sleeve 3 Shaft 5, the shaft 5 include the square shaft 52 of intermediate circular shaft 51 and two sides, and wherein the square shaft 52 of side is located at In second square groove 43, the square shaft 52 of the other side passes through fixed disk 2 and protrudes into turntable 1, and 1 center of turntable is equipped with mating The first square groove 11.

The working principle of the invention is: when original state, two ribs 35 of axle sleeve 3 are stuck in two square holes 27, and Fixed disk 2 is fixed on door by its screw hole 23 opened up above, in this way can not rotary axle box 3, i.e. shaft 5 by handle 4 With fixed disk 2 is relatively fixed to be freely rotated.When holding stop handle 4 and 32 position of cap body with thumb by Lower shaft sleeve 3, make Axle sleeve 3 overcomes the active force of spring 6 to push toward 2 direction of fixed disk, so that two ribs 35 are detached from square hole 27, such hand Handle 4 just can be freely rotated, and rotated by handle 4 and drive shaft 5 and turntable 1, thus can be smoothly by Men Kaiqi.
