Specific embodiment

In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it is necessary to explanation is, On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

The utility model provides a kind of anti-theft handle, as shown in Figure 1, including handle 1, mounting box 2 and locking piece 3, such as schemes Shown in 2-3, rotating member 4, driven wheel 5, chuck 6 and latch assembly 7 are further included；Handle 1 links with rotating member 4, and driven wheel 5 is with turning Moving part 4 engages face-to-face, and rotating member 4 links with locking piece 3；

Chuck 6 is equipped with the circular groove 61 to match with 5 outer diameter of driven wheel；Latch assembly 7 includes spring 71 and holding part 72, one end and the driven wheel 5 of spring 71 other end that offsets couple with holding part 72, the other end and circular groove of holding part 72 61 madial wall offsets.

The anti-theft handle operation principle is as follows：

Opening procedure：Hand-held handle 1 simultaneously rotates, and handle 1 drives rotating member 4 to rotate, and rotating member 4 drives driven wheel 5 to rotate, So as to linkage locking part 3, to complete handle opening procedure, sound can be sent in the process；

Locking process：71 one end of spring squeezes driven wheel 5, the other end squeezes holding part 72, so that holding part 72 and circle 61 inner wall of groove generates big frictional force, so that driven wheel 5 is difficult to opposing circular groove 61 and rotates, and then locking piece 3 is locked Tightly.When lawless people attempts to stir locking piece 3 to open door and window, because of its huge torque, can not possibly substantially complete.And In opening procedure, because rotating member 4 is engaged with institute driven wheel 5 face-to-face, powerful torque is generated, so as to drive spring 71 and clamping Part 72 rotates.

In the utility model, locking piece 3 includes but not limited to the component that shift fork or square shaft etc. are used to be connected locking with door and window.

In the utility model, further, in order to improve active force when holding part 72 and circular groove 61 support, simultaneously Convenient to be rotated under the effect of powerful torque, holding part 72 and the supporting surface of circular groove 61 are in curved surface, and holding part 72 and circle are recessed Slot 61 uses line-line contact.

In the utility model, during in order to improve each rotation, the accuracy for the angle that driven wheel 5 rotates, chuck 6 is along circle The edge of groove 61 is equipped with several arc bayonets 62 to match with holding part 72.I.e. in rotation process, when holding part 72 enters During arc bayonet 62, that is, locking state is presented, until swing handle 1 next time.

In the utility model, the part at least to offset with circular groove 61 is in semi-cylindrical, even more preferably, holding part 72 be cylinder, and the axis direction of the holding part 72 is parallel with the axis direction of driven wheel 5.The latch assembly 7 is preferably with circle The axis of groove 61 is set for symmetry axis in symmetry status, i.e., the latch assembly 7 includes a pair of of spring 71 and a pair of of holding part 72, it is diametrically opposite arranged in circular groove 61.

In the utility model, in order to limit the angle of each rotating handles 1, excessively rotation damage caused by handle is reduced Evil, can further, and anti-theft handle further includes shrapnel 8, and shrapnel 8 is equipped with the V-type holding section 81 with 4 clamping of rotating member, rotates Part 4 is equipped with the rectangle bayonet 41 for 81 clamping of V-type holding section.Yet further, as above, shrapnel 8 compared with rotating member 4 axis Line is in symmetry status, i.e., anti-theft handle includes a pair of of shrapnel 8, diametrically opposite clamping rotating member 4.Matchingly, 4 side of rotating member Edge is equipped with 4 rectangle bayonets, 41,4 rectangular card opening's edge even circumferential distributions.

In the utility model, the driven direction of locking piece 3 and driven wheel 5 include but not limited to that this field often knows by circumference Conversion of motion is the combiner of linear motion：1) when locking piece 3 is shift fork, shift fork moves up and down,：Locking piece 3 The row's driven tooth 31 arranged from top to bottom is equipped with, as shown in figure 4, the another side of driven wheel 5 is equipped with and 31 phase of driven tooth The annular gear wheel 51 matched somebody with somebody；2) when locking piece 3 is square shaft, square shaft is directly sticked in the centre bore of driven wheel 5.

The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model Scope, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to In the utility model scope claimed.
