Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
The present invention provides a kind of anti-theft handle, as shown in figure 1, including handle 1, mounting box 2 and locking piece 3, such as Fig. 2-3 institutes
Show, in addition to tumbler 4, driven pulley 5, chuck 6 and latch assembly 7；Handle 1 links with tumbler 4, driven pulley 5 and tumbler 4
Engagement, tumbler 4 link with locking piece 3 face-to-face；
Chuck 6 is provided with the circular groove 61 to match with the external diameter of driven pulley 5；Latch assembly 7 includes spring 71 and holding part
72, one end and the driven pulley 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 tumbler 4 to rotate, and tumbler 4 drives driven pulley 5 to rotate,
So as to linkage locking part 3, to complete handle opening procedure, during can send sound；
Locking process：The one end of spring 71 extruding driven pulley 5, other end extruding holding part 72, so that holding part 72 and circle
The inwall of groove 61 produces big frictional force, so that driven pulley 5 is difficult to opposing circular groove 61 and rotated, 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 moment of torsion, can not possibly substantially complete.And
In opening procedure, because tumbler 4 engages with institute driven pulley 5 face-to-face, powerful moment of torsion is produced, so as to drive spring 71 and clamping
Part 72 rotates.
In the present invention, locking piece 3 includes but is not limited to the part that shift fork or square shaft etc. are used to be connected locking with door and window.
In the present invention, further, in order to improve active force when holding part 72 and circular groove 61 support while conveniently
Rotated under the effect of powerful moment of torsion, the supporting surface of holding part 72 and circular groove 61 is in curved surface, holding part 72 and circular groove 61
Using line linear contact lay.
In the present invention, during in order to improve each rotation, the accuracy for the angle that driven pulley 5 rotates, chuck 6 is along circular groove
61 edge is provided with some arc bayonet sockets 62 to match with holding part 72.I.e. in rotation process, when holding part 72 enters arc
During bayonet socket 62, that is, locking state is presented, until swing handle 1 next time.
In the present invention, the part at least to be offseted with circular groove 61 is in semi-cylindrical, and even more preferably, holding part 72 is
Cylinder, the axis direction of the holding part 72 are parallel with the axis direction of driven pulley 5.The latch assembly 7 is preferably with circular groove
61 axis is that symmetry axis is set in symmetry status, i.e., the latch assembly 7 includes a pair of springs 71 and a pair of holding parts 72, footpath
To being oppositely disposed in circular groove 61.
In the present invention, in order to limit the angle of each rotating handles 1, excessively rotation infringement to caused by handle is reduced, can
With further, anti-theft handle also includes shell fragment 8, and shell fragment 8 is provided with the V-type holding section 81 with the clamping of tumbler 4, on tumbler 4
Provided with the rectangle bayonet socket 41 for the clamping of V-type holding section 81.Yet further, as above, shell fragment 8 is in relative to the axis of tumbler 4
Symmetry status, i.e. anti-theft handle include a pair of shell fragments 8, diametrically opposite clamping tumbler 4.Matchingly, the edge of tumbler 4 is set
There are 4 rectangle bayonet sockets, 41,4 rectangular card opening's edge even circumferential distributions.
In the present invention, the driven direction of locking piece 3 and driven pulley 5 include but is not limited to that this area often knows by circular motion
It is converted into the combiner of linear motion：1) when locking piece 3 is shift fork, shift fork moves up and down,：Set on locking piece 3
There is the row's driven tooth 31 arranged from top to bottom, as shown in figure 4, the another side of driven pulley 5 is provided with what is matched with driven tooth 31
Annular gear wheel 51；2) when locking piece 3 is square shaft, square shaft is directly sticked in the centre bore of driven pulley 5.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
