The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
As Fig. 1, shown in Fig. 2 and Fig. 3, the improved capper of a kind of latching device, comprise capper main body 11, be movably connected on upper cover (not shown) and the latching device 16 of this capper main body 11, this latching device 16 comprises the latch hook 1 that is fixed at described upper cover and is installed in capper main body 11 and the catch means 14 of the location of matching with latch hook 1, capper main body 11 is provided with lifting groove 13, catch means 14 is fixed in lifting groove 13, the bottom of lifting groove 13 is provided with the lifting mechanism 15(that can control these lifting groove 13 liftings can certainly be provided with in the side of lifting groove 13 lifting mechanism 15 that can control these lifting groove 13 liftings).Capper main body 11 is provided with lifting groove 13, the bottom of lifting groove 13 is provided with the lifting mechanism 15 that can control these lifting groove 13 liftings, catch means 14 is fixed in lifting groove 13, can adjust by lifting mechanism 15 rising and the decline of lifting groove 13, thereby adjust the position of lifting groove 13 interior catch means 14, make catch means 14 coordinate the use of latch hook 1 by position adjustment.
As shown in Figures 2 and 3, catch means 14 comprises mounting groove 12, is installed in the coil tension spring 3 of the spring leaf 4 of mounting groove 12 bottoms, the lock dog 2 that can move up and down and connection groove 12 bottoms and lock dog 2 in mounting groove 12.Lock dog 2 can move downward under the pushing of latch hook 1, upward movement under the effect of coil tension spring 3.By upper cover and 16 pressings of capper main body, catch means 14 is pinned latch hook 1, and upper cover and capper main body 16 are just pinned, and again press upper cover, and catch means 14 is untied the locking to latch hook 1, the latch hook 1 of upspringing, and upper cover and capper main body 16 just can flick.Catch means 14 has been design known in those skilled in the art with this Position Design that coordinates of latch hook 1.Mounting groove 12 bottoms fixedly are equiped with restriction protrusion 10, and coil tension spring 3 is fixed at restriction protrusion 10, make like this coil tension spring 3 more firm with being connected of mounting groove 12 bottoms.
As shown in Figures 2 and 3, lifting mechanism 15 is to arrange like this: lifting mechanism 15 comprise screw rod 7 and with the suitable nut 5 of screw rod 7, screw rod 7 is meshed with nut 5.Nut 5 is fixed at the bottom of lifting groove 13, and screw rod 7 one ends are arranged in nut 5, and screw rod 7 other ends run through the 11 ground settings of capper main body.Screw rod 7 is provided with projection 9, and capper main body 11 is provided with for limiting the up and down position-limited trough of this projection 96.Projection 9 on screw rod 7 and the position-limited trough 6 on capper main body 11 can limit the position of screw rod 7, guarantee that screw rod 7 can not come off,, make in the process of screw rod 7 rotations simultaneously, screw rod 7 is motionless with respect to capper main body 11, and the position of nut 5 can move up and down in capper main body 11.The end that turn screw rod 7 stretches out capper main body 11 can be regulated the oscilaltion of the nut 5 that is sheathed on screw rod 7 outsides, and nut 5 is the bottoms that are fixed at lifting groove 13, so the oscilaltion of nut 5 can drive 13 oscilaltions of lifting groove.The end that screw rod 7 stretches out capper main body 11 is equipped with nut 8, the turn that the setting of nut 8 can convenient screw rod 7.
As shown in Figures 2 and 3, by improvement of the present utility model, capper is after manufacture completes, catch means 14 can also be carried out the position adjustment, greatly reduce in the course of processing requirement to the accuracy rate of the installation site of catch means 14 in latching device 16, also reduce the technical requirements to the producer, greatly improved the efficiency of production work.
Above are only the specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
