Description

A kind of security door lock structure

Technical field

The utility model relates to a kind of security door lock structure, relates in particular to simple in structure, the durable security door lock structure of a kind of handle device.

Background technology

Security door lock structure (shown in accompanying drawing 1-3) is to adopt lock body 1 and handle device to combine in the market, wherein lock body 1 structure as shown in Figure 1, tiltedly tongue 2, back-moving spring 9, hyoplastron 7, back-moving spring 8 all are buckled on the tongue bar 10 in the lock body 1; Back-moving spring 12 is buckled between stator 6a and the main dead bolt 3, and stator 6a one end is buckled between the hyoplastron 7, and the other end and trace 11 be buckle mutually; Trace 11 is snapped on the fixed axis 16, and main dead bolt 3 is fixed on the fixed axis 13; Square lock bolt 4 is independent interlock, is provided with locating slot and is buckled on the lock body 1, rotates by fork 15, drives Square lock bolt 4 move left and right; Lock core hole 14 is located between main dead bolt 3 and the Square lock bolt 4; Lock core is inserted lock core hole, drive main dead bolt 3 move left and right by key rotation lock core, pull back stator 6a because the displacement of main dead bolt drives trace 11 when being moved to the left, stator 6a promotes hyoplastron 7, band mobile tongue rod 10 moves right, thereby opens oblique tongue 2.

The handle device of above-mentioned available technology adopting such as Fig. 2, shown in Figure 3, handle device is made up of square shaft 25, u generating gear spacer 24, back-moving spring 23, the clamp 26 of poke rod 28 cover plates 27, band gear, its structure is that back-moving spring 23 is buckled between u generating gear spacer 24 and the clamp 26, the square shaft 25 of band gear is buckled in the u generating gear spacer 24, the tail end of square shaft 25 is buckled in the square opening of stator 6a of lock body 1 (as shown in Figure 1), and poke rod 28 passes the bottom that cover plate 27 is buckled in u generating gear spacer 24; Stir the rotation that u generating gear spacer 24 move left and right drive square shaft 25 by poke rod, rotate thereby drive stator 6a, stator 6a promotes hyoplastron 7, and band mobile tongue rod 10 moves right, thereby open oblique tongue 2, drive poke rod 28 by back-moving spring 23 again and reset.

Adopt prior art, because the U type gear spacer 24 in the handle device cooperates the square shaft 25 of band gear to rotate, make friction frequent, gear polishes easily; And often compression fracture easily of back-moving spring 23, thereby lose the function of opening oblique tongue, make troubles to daily life.

Summary of the invention

The utility model purpose is to solve above-mentioned weak point of the prior art and a kind of security door lock structure with simple in structure, convenient durable and appearance looks elegant of providing.

The utility model realizes that in the following way a kind of security door lock structure comprises lock body 1, handle, it is characterized in that: the driving lever 19 that is provided with in the described handle is provided with stator 6 in the lock body 1; Driving lever 19 is stirred the stator 6 that is provided with in the lock body 1, to open oblique tongue 2.

Described driving lever 19 is divided into A, B two ends, and the B end is buckled in the U type mouth of stator 6.

Described stator 6 is an integral body, which is provided with U type mouth, circular hole, protrudingly buckles 61 and sliding piece 62, is buckled on the fixed axis 5 by circular hole, and sliding piece 62 is buckled between two hyoplastrons 7, and protruding button 61 and trace 11 be buckle mutually.

The utlity model has handle device durable and appearance looks elegant simple in structure, firm, convenient, is a kind of desirable security door lock structure.

The specific embodiment

The utility model specific embodiment now is described in detail in detail in conjunction with the accompanying drawings, and to shown in Figure 7, the utility model is a kind of security door lock structure, comprises lock body 1, handle, it is characterized in that: the driving lever 19 that is provided with in the described handle is provided with stator 6 in the lock body 1 as Fig. 1; Driving lever 19 is stirred the stator 6 that is provided with in the lock body 1, to open oblique tongue 2.

Described handle is provided with trim 21, driving lever 19, passes the fixed axis 18 of back-moving spring 22, groove cover 20, handle 17, wherein the B of driving lever 19 end passes trim 21, be nested in the groove cover 20, fixed axis 18 passes back-moving spring 22, groove cover 20, driving lever 19 and is riveted on the groove cover 20; The B end of back-moving spring 22 and driving lever 19 and trim 21 be buckle mutually.

The utility model adopts the mounting method of normal door lock to install, and earlier lock body 1 is fixed on the door, and the handle device is fixed on the door again, allows the B of driving lever 19 holds the U type mouth place that just is buckled in stator 6 in the lock body 1 in the handle device; It is the axle center move left and right with fixed axis 5 that thereby the A end of stirring driving lever 19 drives stator 6, promotes hyoplastron 7, and band mobile tongue rod 10 moves right, thereby opens oblique tongue 2.
