Embodiment
Embodiment：As shown in figures 1-8, the invention provides a kind of specific embodiment of hanging locking device, it include lock frame 5,
The fixed plate 6 that is fixedly connected with lock frame 5, it is arranged on passing through and being connected by locking element 7, by the one end of lock frame 5 for the lower section of fixed plate 6
Lock shaft 3, be arranged on lock frame 5 it is interior and adjacent with lock shaft 3 and can be pivoted latch hook 8, be arranged on it is on lock shaft 3 and rotatable
Push rod 14, key 1, one end and the abutting contact of key 1 coordinated with lock shaft 3 and ejector pin 2 that the other end is then in contact with push rod 14,
The first spring 4 between lock shaft 3 and push rod 14 is arranged on, the second spring 13 of the side of push rod 14 is arranged on, is fixed to latch hook 8
Lock frame 5 on steady pin 10, the spacer pin 9 for latch hook 8 to be carried out to rotary stopper, the wind spring 11 being set on steady pin 10,
Lock shaft 3 is fixed to the lock shaft pin 12 locked on frame 5 and push rod 14 is fixed to the crown bar pin 15 on lock frame 5.
Original state is as shown in Fig. 2 ejector pin 2 is assemblied in the centre bore of lock shaft 3, and push rod 14 is arranged on by crown bar pin 15
In the groove of lock shaft 3, second spring 13 is arranged between lock shaft pin 12 and the lower push rod first 142 of push rod 14, the second compressed bullet
Spring 13 makes push rod 14 keep original state, and lock shaft 3 is arranged in lock frame 5 by lock shaft pin 12, and latch hook 8, wind spring 11 pass through fixation
Pin 10 is assemblied on lock frame 5, while the two of wind spring 11 is respectively assembled on lock frame 5 and latch hook 8, the latch hook 8 under the effect of wind spring 11
Trend is rotated clockwise in holding figure, latch hook 8 is maintained in extreme position by spacer pin 9.Simultaneously in latch hook 8 and lock shaft 3
Between the first spring 4 is installed, it is ensured that lock shaft 3 in releasing process can automatic spring reset.Pre- locking function is realized such as Fig. 3 institutes
Show, will by locking element 7 one sections be caught on the hanging column of fixed plate 6, due to latch hook 8 the lower surface of hook portion 81 be inclined-plane, by locking element 7
Hammerlock 71 makes latch hook 8 be rotated around steady pin 10 along diagram opening direction when loading, after being installed in place by locking element 7, in wind spring 11
Under effect, latch hook 8 is rotated around steady pin 10 along diagram prelock direction, now completes the pre- locking function of padlock.When locking padlock
As illustrated in figures 4-5, in the key slot of the insertion of key 1 lock shaft 3, the leading portion of key 1, which withstands ejector pin 2, makes it along diagram compaction direction fortune
It is dynamic, and then push rod 14 is turned to maximum angle along diagram push rod around crown bar pin 15, make in the follow-up rotation process of lock shaft 3,
Upper ejector pin first 141 will not encounter latch hook 8, so as to ensure that locking will not fall off by locking element 7.Key 1 makes lock shaft 3 overall along compression
Direction is moved, and lock shaft pin 12 is departed from the initial slot of lock frame 5, is that next step rotation lock shaft 3 to locked position is ready.As schemed
Shown in 6-7, after key 1 turns to locked position along diagram locking direction, lock shaft projection 31 withstands latch hook 8, makes latch hook 8 can not
Rotated around steady pin 10, while the first spring 4 holds out against lock shaft pin 12 on lock frame 5, it is ensured that lock shaft 3 will not occur during use
Rotate, and then ensure that during use that latch hook 8 by effectively spacing, will not fall off by locking element 7.Releasing process inserts key 1
Afterwards, the jack-up of push rod 14 is made that in first 141 turning course of upper ejector pin latch hook 8 will not be encountered by ejector pin 2, in opposite direction by being locked with Fig. 4
Direction, which rotates key, can complete pre- unblock, and padlock is in pre- lock status after the completion of pre- unblock, as shown in Figure 8, it is necessary to remove by
Locking element, along diagram finger compaction direction pressure lock shaft 3, now second spring 13, which compresses push rod 14, makes it not rotate, lock shaft 3
Moved along finger compaction direction, upper ejector pin first 141 promotes the top of latch hook 8, latch hook 8 is turned around steady pin 10 along diagram unlocking direction
Move to hook portion 81 and separated completely with hammerlock 71, can now be removed by locking element 7.
The present invention coordinates wind spring 11 by the inclined-plane hook portion of latch hook 8, and latch hook after prelock and unblock can be achieved and resets；It is spacing
Pin 9 ensures that latch hook is reset to specified angle, does not result in assembling next time difficult；Pass through the first spring 4 between latch hook 8 and lock shaft 3
Compression is compressed, it is ensured that lock shaft 3 will not rotate after locking；Lock shaft projection 31 is only rotated to can just withstand up to after specified location
Latch hook 8, it is ensured that latch hook 8 is effectively locked；Key 1 coordinates ejector pin 2, push rod 14 is not triggered latch hook 8 during locking and rotates,
Ensure in locking and pre- releasing process, pinned by locking element 7 by latch hook 8；Second spring 13 ensures that push rod 14 is in reset state,
Ensure that push rod 14 can effectively promote latch hook 8 in releasing process simultaneously.The present invention also provides a kind of with above-mentioned padlock simultaneously
The infusion pump of device, can equally realize the object of the invention.
Thus the present invention will be positioned by locking in advance by locking element and padlock, it is to avoid need to hold during existing padlock locking
It is continuous to compress padlock and by locking element.Lock shaft is withstood by key again after pre- locking, locked position is turned to, now latch hook position quilt
Limit the reliable locking for realizing padlock.When needing to remove by locking element, lock shaft is turned into unlocked position with key, now by
Locking element is in pre- locking state, injures ground or people by a crashing object without worrying to be come off by locking element, then the lower lock shaft that press...withes one's finger can use
It is lower by locking element.
Although making specific descriptions to the present invention with reference to the above embodiments, for the ordinary skill people of this area
For member, it should be appreciated that can be carried out within the spirit and scope for not departing from the present invention based on present disclosure
Modification is improved also all within the spirit and scope of the present invention.
