The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Figure 2-5, a kind of pressure handle locking device 001 of this utility model, comprise compacting part, for syringe being pressed on to the pump housing of syringe pump, this compacting part comprises pressure handle 101 and guide rod 102, this pressure handle locking device also comprises: locking member and driver part, and this locking member is connected with this driver part with this compacting part, and this driver part drives this locking member to be locked or release this compacting part.
This locking member comprises housing 203, is placed in the jacking block 202 of housing 203 and is oppositely arranged and is fixed on the slide block 201 on guide rod 102 with jacking block 202 cooperatings and with jacking block 202, guide rod 102 is through housing 203 and slide block 201, and slide block 201 moves along guide rod 102 axial directions housing 203 is interior.This driver part comprises lock core 301 and unlock piece 302, and lock core 301 is provided with lockhole, and unlock piece 302 1 ends coordinate band movable lock core 301 to rotate with this lockhole, and drive jacking block 202 along towards or the direction that deviates from slide block 201 move.
Also be provided with guide pillar 2022 on jacking block 202, accordingly, on housing 203, the position corresponding with guide pillar 2022 is provided with the cavity of annular and both ends open, to accommodate guide pillar 2022, the outer spring 2024 that is arranged with of guide pillar 2022, for making spring 2024 provide active force to jacking block 202, concrete, guide pillar 2022 is provided with the screwed hole be complementary with screw 2025, spring 2024 is through guide pillar 2022, spring 2,024 one ends are fixed on the cyclic convex edge 2031 of cavity one end of housing 203, the other end is fixed on the nut of screw 2025, the diameter of spring is less than the nut diameter of screw 2025, in order to make spring 2024 fixedly on guide pillar 2022, can also be on screw 2025 a sheathed diameter be greater than the pad of spring diameter, pad 2026 pads are below the nut of screw 2025, accordingly, spring 2,024 one ends are fixed on the cyclic convex edge 2031 of housing 203, and the other end is fixed on pad 2026.Lock core 301 1 ends and jacking block 202 junctions are provided with inclined-plane projection 3011, and jacking block 202 is provided with the valley gutter 2023 coordinated with inclined-plane projection 3011, and inclined-plane projection 3011 is rotated with valley gutter 2023 butts and along valley gutter 2023.When unlock piece 302 drives lock core 301 to rotate along a direction in Fig. 4, drive jacking block 202 along moving towards the direction of slide block 201, spring 2024 is compressed, the restoring force contrary with its direction of motion is provided to jacking block 202 simultaneously; When unlock piece 302 drives lock cores 301 when in Fig. 4, a direction rotates backward, drive jacking block 202 to move along the direction that deviates from slide block 201 under the effect of spring 2024.
When being rotated counterclockwise, unlock piece 302 (along a direction in Fig. 4, rotates), unlock piece 302 rotates with movable lock core 301 thereby drives jacking block 202 along moving towards the direction of slide block 201, when jacking block 202 moves to latched position, this latched position is the friction tight position of jacking block and slide block, and jacking block 202 and slide block 201 lockings, during locking, slide block 201 can not move, thereby pressure handle 101 is stretchy not, therefore, syringe is locked on syringe pump.When unlock piece 302 turns clockwise (along a counter-rotation in Fig. 4), unlock piece 302 rotates with movable lock core 301 thereby drives jacking block 202 to move along the direction that deviates from slide block 201, when jacking block 202 moves to unlocked position, this unlocked position is the position that slide block can just slide on jacking block, jacking block 202 and slide block 201 releases, during release, slide block 201 can move by the axial direction along guide rod 102 above jacking block, thereby can pull pressure handle, take off syringe.
Clearly, the direction of rotation difference of unlock piece, while driving the jacking block motion, its direction of motion is also different, can do different settings according to use habit, on bevel direction that can also be by adjusting the inclined-plane projection on lock core and jacking block, the bevel direction of valley gutter is adjusted.
A kind of pressure handle locking device of this utility model, by locking member and driver part are set, this driver part can drive described locking member to be locked or release this compacting part, when compacting part locks, fixedly the pressure handle of syringe can't move, need corresponding unlock piece carry out release to locking member, and make just can pull pressure handle after the compacting part release, can effectively prevent other people syringe that helps himself freely to.
This utility model also provides a kind of syringe pump, as shown in Figure 1, this syringe pump 002 comprises the pump housing 50, is arranged on syringe 40 and this pressure handle locking device on the pump housing 50, this pressure handle locking device can be locked in syringe 40 on syringe pump, during locking, does not have corresponding unlock piece can't take off syringe, when needs take off syringe, get final product release with corresponding unlock piece, after release, pull pressure handle can take off syringe.Therefore, limited the use of syringe pump, the potential safety hazard of having avoided other people random operating syringe to bring, improved the security performance of syringe pump.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace.
