Abstract
A kind of liquid getting device preventing rifle head from coming off.It is provided with on the top of body to get liquid control button and rifle head exit button, capacity adjustable spiral mechanism, piston rod and elastic suction nozzle is respectively equipped with in the below of getting liquid control button, sleeve is provided with in the below of rifle head exit button, be provided with elastic claw at the bottom margin of sleeve, the bottom of elastic claw is provided with the raised line of lockable rifle head.During use by rifle headgear on elastic suction nozzle, the top circle hat of rifle head will enter in elastic claw, and pinned by elastic claw, when pressing rifle head exit button, rifle head is released by sleeve, because rifle head is pinned by elastic claw, thus can't be ejected when rifle head exits elastic suction nozzle completely, ensure that the security of operation.
Description
Technical field
The utility model relates to a kind of use for laboratory product, is a kind of liquid getting device preventing rifle head from coming off specifically.
Background technology
Existing liquid getting device is be provided with on the top of body to get liquid control button and rifle head exit button at it, is respectively equipped with capacity adjustable spiral mechanism, piston rod and elastic suction nozzle, is provided with sleeve in the below of rifle head exit button in the below of getting liquid control button.During use, first by rifle headgear on elastic suction nozzle, then pressing is got liquid control button and can be carried out getting liquid operation, and after completing and getting liquid, pressing is got liquid control button and the liquid in rifle head can be discharged again.After completing discharge opeing operation, pressing rifle head exit button, rifle head exit button drives the sleeve below it that rifle head is released elastic suction nozzle.In actual mechanical process, easily occurring that rifle head and elastic suction nozzle fix phenomenon loosely, there is the problem of landing from elastic suction nozzle in rifle head in operation.And after drained got liquid, when pressing rifle head exit button carries out exiting operation, because rifle head is connected comparatively tight with elastic suction nozzle, stronger resistance will be subject in the starting stage of pressing rifle head exit button, the strength that people use also will strengthen thereupon.Also can't disappear immediately in the strength of the moment people that rifle head exits, thus easily occur the phenomenon that rifle head ejects from elastic suction nozzle.If rifle head is getting landing in liquid process, then got liquid can spill from rifle head, impacts the safety of environment and people.Due to rifle first as small volume and be water white transparency object, if rifle head ejects from elastic suction nozzle when normally exiting, it falls on the ground also pole and not easily be it is found that, is not easy to people and processes refuse, makes troubles to the use of people.
Summary of the invention
In order to solve existing liquid getting device Problems existing, the utility model provides a kind of liquid getting device preventing rifle head from coming off, and this liquid getting device not only conveniently carries out liquid sampling, and can effectively prevent rifle head from coming off from the elastic suction nozzle of liquid getting device.
The utility model solves the technical scheme that its technical problem adopts: it is provided with on the top of body to get liquid control button and rifle head exit button, capacity adjustable spiral mechanism, piston rod and elastic suction nozzle is respectively equipped with in the below of getting liquid control button, sleeve is provided with in the below of rifle head exit button, simultaneously bottom margin is under a bushing provided with elastic claw, and the bottom of elastic claw is provided with the raised line of lockable rifle crown portion circle hat.During operation, by rifle headgear on elastic suction nozzle, the top circle hat of rifle head pins by the elastic claw under sleeve, to guarantee that rifle head can not come off in operation.
The beneficial effects of the utility model are: do not affect get liquid operation while, rifle head effectively can be avoided to come off from liquid getting device, be beneficial to people and operate.The utility model product structure is simple, and cost is low, easy to operate, is beneficial to and promotes the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is portion of the present utility model face structural representation.
Code description in figure: 1-body; 2-gets liquid control button; 3-rifle head exit button; 4-capacity adjustable spiral mechanism; 5-piston rod; 6-elastic suction nozzle; 7-sleeve; 8-elastic claw; 9-raised line.
Detailed description of the invention
As shown in Figure 1, be provided with on the top of body (1) and get liquid control button (2) and rifle head exit button (3), capacity adjustable spiral mechanism (4), piston rod (5) and elastic suction nozzle (6) is respectively equipped with in the below of getting liquid control button, sleeve (7) is provided with in the below of rifle head exit button, simultaneously bottom margin is under a bushing provided with elastic claw (8), and the bottom of elastic claw is provided with the raised line (9) of lockable rifle crown portion circle hat.During practice, elastic claw adopts elastic caoutchouc to make, general side under a bushing establishes 3-4 elastic claw, leave space between elastic claw, on elastic claw, the thickness of raised line can touch elastic suction nozzle with it and is advisable, and can effectively lock rifle head like this, thus can guarantee that rifle head in operation can not self falling, even if when carrying out exiting operation, rifle head also can not eject from suction nozzle by sleeve thrust, reaches the object be convenient to people and used.
