Abstract
The utility model discloses a chemical detection sampler which comprises a screw rod, a needle head and a pipe body with graduations; a push rod is arranged in the pipe body; the length of the push rod is the same as that of the screw rod; a fixed ring is sleeved outside the pipe body; an inner threaded hole is formed in the fixed ring; the front end of the screw rod passes through the inner threaded hole in the fixed ring; the tail end of the screw rod is movably connected with a positioning rod. When the chemical detection sampler is used, at first, corresponding graduations are found according to the sample quantity requirement, then the screw rod is moved forwards to enable the front end of the screw rod to be positioned at corresponding graduations, at the moment, the push rod in the pipe body is pushed, a liquid to be detected is sucked in the pipe body from the needle head, and as the length of the push rod is the same as that of the screw rod, when the push rod is moved backwards and is in contact with the positioning rod at the tail end of the screw rod, the quantity of the drawn liquid to be detected can meet the requirement and working personnel is reminded to finish the sampling.
Description
Technical field
The utility model relates to applied chemistry instrument field used, especially a kind of chemical detection sampler.
Background technology
In the applied chemistry field, the detection of liquid chemicals is frequent work, and the taken amount of detected liquid requires very strictly mostly the time, but lacks at present corresponding sampler.
The utility model content
The utility model technical assignment is for above-mentioned technical deficiency, and a kind of chemical detection sampler is provided.
The technical scheme that the utility model technical solution problem adopts is: the chemical detection sampler, comprise screw rod, syringe needle and with the body of scale, be provided with push rod in described body, the length of described push rod equates with spiro rod length, described body is socketed with set collar outward, this set collar is provided with an internal thread hole, and described screw front end is through the internal thread hole on set collar, and described screw rod end is connected with backstay.
The beneficial effect that the utility model can bring is: effectively improved the precision of quantity of sampling quantity when liquid chemicals detects, and also simple in structure, easy to operate.
The accompanying drawing explanation
Fig. 1, the utility model one-piece construction schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described below:
As shown in Figure 1, the utility model discloses a kind of chemical detection sampler, comprise screw rod 6, syringe needle 5 and with the body 4 of scale, be provided with push rod 2 in described body 4, the length of described push rod 2 and screw rod 6 are equal in length, and described body 4 is outer is socketed with set collar 3, and this set collar 3 is provided with an internal thread hole 7, described screw rod 6 front ends are through the internal thread hole 7 on set collar 3, and described screw rod 6 ends are connected with backstay 1.
During use, first according to the quantity of sampling quantity requirement, find corresponding scale on body 4, then move forward screw rod 6, make screw rod 6 front ends be positioned at corresponding scale place, at this moment pull the push rod 2 in body 4, testing liquid in syringe needle 5 is drawn into body 4, because length and the screw rod 6 of described push rod 2 are equal in length, thus when push rod 2 mobile while encountering the backstay 1 of screw rod 6 ends backward, mean that the testing liquid quantity that extracts has satisfied the demands, remind the staff to sample end.The precision of quantity of sampling quantity when the utility model can effectively improve the liquid chemicals detection, and simple in structure, easy to operate.
