Abstract

The utility model discloses the lock body of the down pressing type lock opening, comprising a lock shell, an oblique spring bolt which is connected with an oblique spring bolt linkage rod, a rotary oblique spring bolt shifting block and a shifting piece. The utility model is characterized in that the shifting piece is provided with a reset torsion spring, a positioning hole which is matched with the handle, and a downward concave part; the shifting piece is abutted with the upper end of the oblique spring bolt shifting block through the downward concave part, and the oblique spring bolt shifting block plays the linkage action and drives the oblique spring bolt linkage rod to move into the lock shell; the utility model has simple structure, easy use and labor saving. When in use, the door handle is downward pressed, and the oblique spring bolt retracts into the lock shell to open the door, through the synchronized motion of the shifting piece, the oblique spring bolt shifting block and the oblique spring bolt linkage rod. The lock body of the down pressing type lock opening is applied to various anti-theft locksets.

Description

The press-down type lock body of unblanking

Technical field

The utility model relates to a kind of lockset.

Background technology

At present, door lock on the market for insure, antitheft for the purpose of, generally all adopt double lock tongue (skew bolt lock and cylinder dead bolt) mode, the stretching motion of cylinder dead bolt generally drives by the rotation of key, and tiltedly the stretching motion of tongue then generally is to drive by rotating inside and outside handle, owing to adopt the mode of rotating, apply relatively difficulty of external force, if particularly the door opener has taken thing or old man, child etc. to open the door on hand, it is just relatively more difficult to reverse handle, therefore uses comparatively inconvenient.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides more laborsaving, the press-down type lock body of unblanking easily of a kind of use.

The purpose of this utility model is achieved in that a kind of press-down type lock body of unblanking, comprise lock housing, the oblique tongue that links to each other with oblique tongue connecting rod and rotating oblique tongue shifting block and plectrum, it is characterized in that: described plectrum is provided with reduction torsion spring, the locating hole that cooperates with handle and protuberance down, plectrum by protuberance down with play the oblique tongue shifting block that the oblique tongue connecting rod of driving of interlock effect moves in lock housing on offset.

The utility model is simple in structure, and is easy to use and laborsaving, during use, as long as Door handle is pressed toward next, and by plectrum, tiltedly tongue shifting block and oblique being synchronized with the movement of tongue connecting rod, can be with oblique tongue retraction lock housing, thus door is opened.The utility model can be applicable on the various locks.

Description of drawings

Fig. 1 is a cut-away view of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model comprises, comprises lock housing 1, oblique tongue connecting rod 43, oblique tongue 4, oblique tongue shifting block 3 and plectrum 2 etc.Lock housing 1 is fixed in by rivet 21 in plectrum 2 middle parts, can rotate for the axle center by rivet 21, and a reduction torsion spring 22 is socketed on rivet 21, one ends and props up lock housing 1 inwall, and the other end props up plectrum 2, and plectrum 2 is automatically reset.The location square hole 24 that plectrum 2 is provided with down protuberance 23 and can be used with handle.Tiltedly tongue shifting block 3 is fixed in lock housing 1 by rivet 31, can rotate for the axle center by rivet 31, and its upper end offsets with the following protuberance 23 of plectrum 2, and the lower end links to each other with oblique tongue connecting rod 43 latter ends.Tiltedly tongue connecting rod 43 runs through a stator 42 that is fixed on the lock housing 1, socket one back-moving spring 41 on the body of rod between stator 42 and the oblique tongue 4.

During use, with Fig. 1 is example, the handle that will be fixed in location square hole 24 is toward pressing down, driving plectrum 2 rotates counterclockwise, compression torsion spring 22, oblique tongue shifting block 3 of protuberance 23 drives clockwise rotates under it, promptly drives oblique tongue connecting rod 43 toward right motions, compression reseting spring 41, thus tiltedly in the tongue 4 retraction lock housings 1 door is opened simultaneously.Men Kaihou looses one's grip, and the reaction force of torsion spring 22 upwards resets plectrum 2, and the reaction force of back-moving spring 41 ejects oblique tongue 4 outside the lock housing 1 again simultaneously.

The utility model can be used according to antitheft requirement and various antitheft cylinder dead bolt.In the present embodiment, as shown in Figure 1, the side's of being provided with tongue 5 also below oblique tongue, the end of the double wedge side of the being connected in tongue 5 of side's tongue thumb wheel 51, this double wedge links to each other with back-moving spring 52, and the other end of back-moving spring 52 is fixed on the lock housing 1 with rivet 53, side's tongue 5 is provided with a upper convex portion 54, be positioned at oblique tongue 4 and move on the moving passage, can hinder oblique tongue 4 and in lock housing 1, move, but the other side's tongue 5 carries out spacing simultaneously.Flexible by the key side of drive tongue 5 during use, after laying the key under the door, square tongue 5 stretches out lock housing 1 to upper convex portion 54 to the right and props up lock housing 1 inwall, and this moment, upper convex portion 54 upper ends propped up the end of oblique tongue 4 simultaneously, thereby had played the effect of double anti-theft.
