Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
The door handle mechanism that this anti-opal is opened, including unlocking button 1, door handle 3, slide bar 5, straight pin 6, spring 7, Door lock casing 8 and base plate 9, door handle 3 has rotating shaft section 3.1, axle bed section 3.2 and operation handle 3.3, inner end in axle bed section 3.2 is connected with rotating shaft section 3.1, is fixed with operation handle 3.3 in axle bed section 3.2；It is fixed with base plate 9 at the back side of Door lock casing 8, the rotating shaft section 3.1 of door handle 3 is rotatably installed on Door lock casing 8, unblock button jack 3.4 is offered in rotating shaft section 3.1 and axle bed section 3.2, in the leading portion unlocking button jack 3.4, sliding plug has and unlocks button 1 and offer at the inner end of rotating shaft section 3.1 and lock groove 3.5, notch one offside locking groove 3.5 has chamfering, and another offside keeps right angle；The outer section of described slide bar 5 is cylindrical section 5.1, the inner segment of slide bar 5 is for limiting meander sections 5.2, and the size of cylindrical section 5.1 is more than the size limiting meander sections 5.2, base plate 9 offers and limits the restriction rotary hole 9.1 that meander sections 5.2 matches, the restriction meander sections of slide bar 5 is inserted in the restriction rotary hole 5.2 of base plate 9, cylindrical section 5.1 sliding plug is in the back segment unlocking button jack 3.4, rearward end at cylindrical section 5.1 offers straight pin jack 5.3 along its diametric(al), it is fitted with straight pin 6 at straight pin jack 5.3, the restriction meander sections of slide bar 5 is socketed with spring 7, the inner end of spring 7 offsets with base plate 9, the outer end of spring 7 is against on the rear end face of cylindrical section 5.1.
The rotating shaft section 3.1 inner end cylindrical of door handle 3 offers the first jump ring mounting groove, the first jump ring 2 is installed in the first jump ring mounting groove.
The inner end cylindrical unlocking button 1 offers the second jump ring mounting groove, the second jump ring 4 is installed in the second jump ring mounting groove.
The shape of cross section of described restriction meander sections 5.2 is triangle, square, rectangle or other polygons.
The rotating shaft section 3.1 of door handle 3 is rotatably installed on Door lock casing 8 by this utility model by the first jump ring 2, the axis unlocking button 1 through the unblock button jack 3.4 of door handle 3 and is fixed against abjection by the second jump ring 4, the cylindrical section 5.1 of slide bar 5 is matched in clearance with the unblock button jack 3.4 of door handle 3, and the restriction meander sections 5.2 of slide bar 5 is through the restriction rotary hole 9.1 on base plate 9.Spring 7 is enclosed within restriction meander sections 5.2, and the inner end of spring 7 withstands base plate 9, and slide bar 5 is pushed up to unlocking button 1 by the outer end of spring 7.Straight pin 6 passes the straight pin jack 5.3 of slide bar 5 and sinks to locking in groove 3.5 on door handle 3.
As it is shown in figure 5, rotating shaft section 3.1 position of door handle 3 has and locks groove 3.5, notch one offside locking groove 3.5 has chamfering, and another offside keeps right angle.
During normal door, pressure unlocks button 1, unlocks button 1 and promotes slide bar 5 to slide axially rearward, and what straight pin 6 departed from door handle 3 locks groove 3.5, and the operation handle 3.3 of lower door handle 3 can open the door.
If not depressing unblock button 1, straight pin 6 is stuck in the groove 3.5 inner barrier door handle 3 of locking of door handle 3 and rotates, and now door handle 3 cannot press off door down.
Carrying when locking on the operation handle 3.3 of door handle 3, exist because locking the notch offside chamfering of groove 3.5 on door handle 3, straight pin 6 is skidded off by this chamfering to be locked outside groove 3.5, and door handle 3 completes to carry on normal, and antitheft door is locked.
