Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in detail.This figure is the schematic diagram simplified, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Refer to shown in Fig. 1-Fig. 3, a kind of guardrail of the present utility model, including locking device with by the interconnective column of this locking device 3 and mesh sheet 4.
Wherein, locking device includes that locking body 1 lock onto well the latch hook 2 on body 1, locks the lock housing 11 that body 1 includes a pair mutually fastening, fixing connection by the way of welding between the two lock housing 11.Corresponding on the medial wall that two lock housings 11 are relative offering tilting chute 12, between two chutes 12, travelling carriage is provided with lock pin 13.Latch hook 2 one end is set to inclined-plane 21, top end opening and tilting draw-in groove 22 is offered on latch hook 2, draw-in groove 22 is contrary with the incline direction of chute 12, one end of lock housing 11 offers socket 14, socket 14 is inserted in the one end on latch hook 2 with inclined-plane 21, (i.e. inserting along the direction of arrow as shown in Figure 2) lock pin 13 is connected to inclined-plane 21 and can slide to draw-in groove 22 porch on latch hook 2 top along inclined-plane 21, now change the moving direction (i.e. moving) of latch hook 2 along the arrow wind opposite direction shown in Fig. 2, lock pin 13 is made to be connected in draw-in groove 22, thus latch hook 2 is lock onto on body 1.
Moving in chute 12 and draw-in groove 22 for the ease of lock pin 13, the lock pin 13 in the present embodiment is designed as cylindrical structural.
In order to ensure the inclined-plane 21 that lock pin 13 can be connected on latch hook 2, the lower surface height of latch hook 2 is less than the lowest part height of chute 12；In order to ensure that lock pin 13 can arrive the top of latch hook 2, the upper surface height of latch hook 2 is less than the height of at least one lock pin 13 diameter of highest point of chute 12.
Crooked in order to ensure that lock pin 13 does not occur during by the slope driving of latch hook 2, so that the two ends of lock pin 13 depart from the axis perpendicular of chute 12, the moving direction of latch hook 2 and described lock pin 13, the middle part of lock pin 13 is connected to inclined-plane 21.
Chute 12 inclined angle alpha with respect to the horizontal plane is 120 °～150 °, and draw-in groove 22 angle of inclination beta with respect to the horizontal plane is 30 °～60 °.In the present embodiment, the value of α is 135 °, and the value of β is 45 °.
The edge of above-mentioned mesh sheet 4 is fixed with framework 41, and framework 41 is connected away from the one end on inclined-plane 21 is fixing with on latch hook 2, and column 3 is fixed with one end away from socket 14 in lock housing 11 and is connected.
Locking device of the present utility model, latch hook 2 once lock onto on body 1, anyway pulls latch hook 2, it all can not be made to depart from from lock body 1, serve good locking effect, be used in guardrail by this locking device, it is possible to be greatly improved the anti-theft feature of guardrail.Locking device of the present utility model, simple in construction, easy to operate, remarkably productive, be suitable to promote.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this utility model.The technical scope of this utility model is not limited to the content in description, it is necessary to determine its technical scope according to right.
