Detailed description of the invention
Fig. 1 is a kind of schematic front view of anti-theft type U-shield；
The enlarged diagram that Fig. 2 is in anti-theft type U-shield described in Fig. 1 I；
Fig. 3 is the structural schematic diagram of elastic component in Fig. 2.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
As shown in Figs. 1-2, a kind of anti-theft type U-shield, including U-shield ontology 1, one end of U-shield ontology 1 are connected with hanging fastener 2,
It is characterized in, is connected with shell 3 at the open end of the hanging fastener 2, the inner rotation of shell 3 is equipped with gear 4, and the one of gear 4
Side engagement is connected with the rack gear 13 being slidably connected with shell 3, and one end of rack gear 13 is connected with the moving member 14 through shell 3, moves
The end of moving part 14 can be contacting and separating to be closed and open hanging fastener 2 with hanging fastener 2, be arranged between two teeth of the gear 4
Have a unidirectional limited block 5, unidirectional limited block 5 be in towards gear 4 one end is narrow and right-angled trapezium shape that the other end is wide, turn in shell 3
It is dynamic that U-shaped board body 6 is installed, and the pivot center of U-shaped board body 6 is overlapped setting, the unidirectional limited block with the pivot center of gear 4
5 side is connected with the mobile bar 7 across U-shaped board body 6, and unidirectional limited block 5 is connect by elastic component with U-shaped board body 6, the shell
Strip notch 10 is offered on the wall body of body 3, mobile bar 7 passes through strip notch 10；
As shown in Fig. 2, inclined-plane in the right-angled trapezium shape of unidirectional limited block 5 at this time towards downside and with gear 4
Tooth contact, and unidirectionally the plane in the right-angled trapezium shape of limited block 5 is towards the upside also tooth contact with gear 4, then back and forth
With mobile bar 7 is stirred down on hand, since the pivot center of U-shaped board body 6 is overlapped setting with the pivot center of gear 4, on
When back and forth stirring mobile bar 7 down, it will drive the one end of U-shaped board body 6 far from gear 4 and also move back and forth up and down, and U-shaped board body 6
It can up and down reciprocatingly be swung around 4 axis of gear, therefore make unidirectional limited block 5 also around the axis oscillating of gear 4；When unidirectional
Limited block 5 around gear 4 axis to lower swing when, the downside inclined-plane of unidirectional limited block 5 receives the shock of the tooth on gear 4
Power, therefore the separation for keeping unidirectional limited block 5 mobile towards left side by one, to make unidirectional limited block 5 around gear 4
When axis is to lower swing, unidirectional limited block 5 is jacked up and crosses the tooth on gear 4, at this time can not be with the rotation of moving gear 4；
And after unidirectional limited block 5 is to lower swing a certain range, then move up mobile bar 7, so that U-shaped board body 6 be made to put upwards
Dynamic, the axis with unidirectional limited block 5 around gear 4 is swung up, and makes the upper side plane and gear 4 of unidirectional limited block 5 at this time
Tooth contact, then unidirectional limited block 5 will not be jacked up towards left side, but the tooth headed on gear 4 is swung, to make
The clockwise rotation of gear 4 moves down moving member 14 to move down with carry-over bar 13, i.e. openable at this time
Hanging fastener 2, convenient for hanging over hanging fastener 2 at the positions such as trousers ring.
After the mounting well of hanging fastener 2, then towards left side pull-up mobile bar 7, and mobile bar 7 is rotated 180 °, list at this time
It is the shape that inclined-plane is towards upside and plane is towards downside, reciprocal again to stir mobile bar 7, principle and above-mentioned to limited block 5
Process is almost the same, the differ in that being that gear 4 is carried out anticlockwise rotation at this time, then makes on rack gear 13
It moves, hanging fastener 2 is moved up and be closed with moving member 14, and since the plane of unidirectional limited block 5 at this time is directed towards downside
(being not shown in the figure, shape is the shape that the unidirectional limited block 5 in Fig. 2 overturns 180 °), therefore unidirectional limited block 5 hinders tooth
The clockwise rotation of wheel 4, so that being in gear 4 can rotate in an anti-clockwise direction but clockwise cannot rotate
Unidirectional locking state, therefore prevent moving member 14 from moving down, then cannot open hanging fastener 2, only being drawn towards left side again
Mobile bar 7 is played, and mobile bar 7 is rotated 180 °, unidirectional limited block 5 is made to be again at state as shown in Figure 2, and past physical pendulum
Dynamic mobile bar 7, could open hanging fastener 2.
After moving member 14 after hanging fastener 2 is shifted up is closed, only reciprocally swinging mobile bar 7 can just make moving member in person
14 move down to open hanging fastener 2, and the utility model has good anti-theft capability, and there is no the feelings not paid attention in user
The problem of being taken down hanging fastener 2 under condition, improves security capabilities.
Further, as shown in Fig. 2, the inner wall of the shell 3 is connected with elastic telescopic device, the work of elastic telescopic device
Moved end is connected with two-way resistance limited block 18, and two-way resistance limited block 18 is located between two teeth of gear 4, and two-way resistance limits
Block 18 hinders the rotation of gear 4 in certain range of resistance, and the two-way resistance limited block 18 is in isosceles-trapezium-shaped, and two
The inclined-plane of side is respectively facing two teeth of gear 4；Turn counterclockwise by the effect of two-way resistance limited block 18, therefore to gear 4
It is dynamic and when rotating clockwise, it is required to eject two-way resistance limited block 18, gear 4 is made to overcome certain resistance just and can be carried out turn
It is dynamic, therefore avoid due to gravity of moving member 14 etc. and driving to gear 4 makes gear 4 rotate；It should be noted that gear
The shock for the tooth for overcoming the resistance of two-way resistance limited block 18 to be greater than on the inclined-plane shock gear 4 of unidirectional limited block 5 when 4 rotation
Power avoids gear 4 that from also rotating when the inclined-plane of unidirectional limited block 5 hits gear 4.
As shown in figure 3, the elastic telescopic device includes the cylinder 16 connecting with the inner wall of shell 3, setting in cylinder 16
There is the first compressed spring 19, cylinder 16 is towards one end of gear 4 inserted with movable part 17, one end of movable part 17 and the first compression
Spring 19 connects, and the other end of movable part 17 connect with two-way resistance limited block 18, makes two-way resistance limited block 18 due to gear
4 rotation and when being ejected between two teeth, the first compressed spring 19 has certain retraction ability.
Further, the inner wall of the shell 3 is fixedly connected with fixed plate 12, and the side of fixed plate 12 towards gear 4 is opened
Equipped with sliding slot, rack gear 13 is slidably connected in sliding slot, improves the stability that rack gear 13 slides.
Further, the end of the moving member 14 forms salient point 15, and salient point 15 can be accommodated by offering on hanging fastener 2
Groove, when moving up moving member 14 with the closure of hanging fastener 2, salient point 15 is entered in groove, improves the stability of closure.
Preferably, the elastic component is the helical spring 9 being set in mobile bar 7, the manufacture or buying of helical spring 9
Cost is relatively low, and has enough strokes.
Preferably, the U-shaped board body 6 is connect by the second compressed spring 11 with the inner wall of shell 3, convenient for moving down
After mobile bar 7, by the reset capability of the second compressed spring 11, move up mobile bar 7 automatically to reset, using more
It is convenient.
Preferably, the end of the mobile bar 7 outside shell 3 is connected with handle 8, convenient for hand-held 8 side of handle
Just mobile mobile bar 7, it is easy to use.
