Embodiment

A kind of lock for theft-proof door as shown in Fig. 1-Fig. 7, including handle head 100 and square core print seat 200, square core print seat 200 pass through Socket mode is inserted in handle head 100, and handle head 100 has with square core print seat 200 rotates against state and linkage status, handle head 100 side walls are equipped with the first through hole 110 moved back and forth for removable pin 120, and the side wall of square core print seat 200 is equipped with fits with removable pin 120 The groove 210 matched somebody with somebody, further includes the push-rod assembly 300 that control removable pin 120 moves back and forth, rotates against state and linkage status lead to Mutually switching is realized in the reciprocating motion for crossing removable pin 120, and square core print seat 200 is for being inserted into Fang Xin, Fang Xin and door handle 400 Dynamic, handle head 100 and square core print seat 200 are fixed in panel 600 by cover board 500, and with fastened by screw, 120 He of removable pin What the cooperation of groove 210 was used for switching handle head 100 and square core print seat 200 rotates against state and linkage status, when removable pin 120 When being inserted into groove 210, handle head 100 and square core print seat 200 realize linkage status, when removable pin 120 leaves groove 210, hold 100 state is rotated against with the square realization of core print seat 200 at hand, the state that rotates against is tamper-proof.

The hole sectional area of the first through hole 110 tapers into from outside to inside, this is to make spring 140 logical first Blocked in hole 110.

Including fixing sleeve 130 and spring 140, fixing sleeve 130, removable pin 120 and spring 140 in first through hole 110 according to Secondary assembling；Fixing sleeve 130 is fixedly connected with the inner wall of first through hole 110, and 130 center of fixing sleeve is equipped with and leads to for removable pin 120 The second through hole 131 crossed；Removable pin 120 has elastic restoring force, fixing sleeve 130 and first through hole 110 in first through hole 110 Inner wall the mode such as tight fit can be used to be fixedly connected, the length of removable pin 120 is more than the depth of first through hole 110, spring 140 Under in the raw, one end of removable pin 120 is protruded outside handle head 100.

120 side wall of removable pin has receiving part 121, and the receiving part 121 of removable pin 120 is inserted into fixing sleeve 130 and bullet Between spring 140, the sectional area of receiving part 121 is more than the hole sectional area of the second through hole 131, and thus 121 side of receiving part is played To the spacing of removable pin 120, opposite side coordinates spring 140 removable pin 120 is had elastic restoring force.

The push-rod assembly 300 includes impeller 310, and one end of impeller 310 is equipped with fitting removable pin 120 vertically upward Flange 311；Impeller 310 is equipped with two guide grooves 312, including two screws 340 coordinated with two guide grooves 312, Impeller 310, which is realized, to be moved back and forth；The hole 313 for the installation of switch 320, switch 320 and impeller are additionally provided with impeller 310 310 realize linkage, and switch 320 is consolidated with the hole 313 on impeller 310 by modes such as tight fit mode, socket mode or buckles Fixed connection；Two screws 340 are integrally fixed in panel 600, and impeller 310 is past under the cooperation of guide groove 312 and screw 340 Multiple movement；Flange 311 is linked for coordinating with removable pin 120.

The flange 311 is curved flanges 311, and flange 311 designs camber, is to allow door handle 400 in 100 He of handle head Rotated under square 200 linkage status of core print seat more smooth.

The push-rod assembly 300 includes the spacing strip 330 with elastic restoring force, in spacing strip 330 it is symmetrical inwardly Equipped with limit protrusion 331, spacing strip 330 is fixedly connected similar to U-typed structure, bending place with screw 340, can be by screw The modes such as nut and gasket are inserted in 340 fastens spacing strip 330, and limit protrusion 331 can be triangle or arc etc., limit Position protrusion 331 is located at the opposite parallel-segment of spacing strip 330, plus the elastic restoring force of spacing strip 330, limit protrusion 331 Just play spacing transitional function, during moving switch 320, switch 320 makes at the limit protrusion 331 of spacing strip 330 Deform upon and force spacing strip 330 that there is reaction force, when switch 320 is moved to more than maximum high spot, in reaction The lower of power can allow switch 320 to move to destination locations rapidly.

320 side walls of the switch are equipped with the first grooving 321 and the second grooving 322, and switch 320 passes through 321 He of the first grooving Spacing strip 330 is flexibly connected, and switchs 320 cooperations by the first grooving 321 and spacing strip 330, is realized and is moved back and forth, face Plate 600 is equipped with the mounting hole for installation switch 320, and the second grooving 322 is flexibly connected for coordinating with the hole wall of mounting hole.

One end of the spacing strip 330 is fixedly connected with one of screw 340, and the of other end insertion switch 320 One grooving 321, switch 320 are located at the side of limit protrusion 331.

Under normal use pattern, switch 320 is up pushed away, push-rod assembly 300 under being linked of switch 320 up Movement, due to switch 320 and the position relationship of spacing strip 330, push-rod assembly 300 is in the top clamping, at this time in impeller Under the cooperation of 310 flange 311 and removable pin 120, in the groove 210 of 120 entrance side's core print seat 200 of removable pin, 100 He of handle head Square core print seat 200 is in linkage status, is at this moment just opened the door with door handle 400, and door handle 400 is during rotating, flange 311 are bonded removable pin 120 always；When anti-theft modes to be switched to, switch 320 down pushes away, and push-rod assembly 300 is in switch 320 Being linked under down move, due to switch 320 and spacing strip 330 position relationship, push-rod assembly 300 is in bottom card Tightly, removable pin 120 moves and the groove of the side's of leaving core print seat 200 210 under the action of spring 140 to outside handle head 100 at this time, Handle head 100 and square core print seat 200 are in and rotate against state, at this moment rotate door handle 400 for idle running, play anti-theft function, pin To the criminal offence by destroying opal burglary.

The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description The principle for simply illustrating the utility model, it is on the premise of not departing from the spirit and scope of the utility model, in the art common Technical staff simple change and to replace all be within the scope of protection of the utility model.
