Description

Inhale appearance needle depth setting device Technical Field The utility model relates to the technical field of medicine dissolution detection, in particular to a sample suction needle depth setting device. Background In the detection process of the medicine dissolution rate, rapid and accurate sampling is an important link, the existing determination of the depth of the sample suction needle is generally positioned by using a ruler or a positioning plate, and the problems of low positioning accuracy, large artificial operation error, repeated confirmation in the sampling process and the like exist. Disclosure of utility model In order to solve the problems, the utility model provides the sample suction needle depth setting device which can realize accurate positioning, is easy to adjust and has stable and reliable sample suction process. In order to achieve the purpose, the utility model adopts the following technical scheme that the sample suction needle depth fixing device comprises a sample suction needle and a depth fixing clamping block, wherein the bending end of the sample suction needle is sleeved with a hoop, an elastic sheet is arranged on the hoop, the tail end of the elastic sheet is provided with a bulge, the depth fixing clamping block is in a ladder shape, each step is provided with a groove, and each step of the depth fixing clamping block is carved with a corresponding depth. The sample sucking needle is also sleeved with a separation sheet, and the separation sheet is arranged at the lower end of the anchor ear. The sample suction needle is made of corrosion-resistant plastic. The width of each step of the depth fixing fixture block is consistent with the width of the sample sucking needle. The fixed-depth clamping block is made of corrosion-resistant plastic. Compared with the prior art, the utility model has the beneficial effects that the positioning of the depth of the sample sucking needle is realized by arranging the stepped depth fixing clamping blocks and matching the protrusions on the elastic sheet with the grooves of the depth fixing clamping blocks, and the redundant length of the sample sucking needle can be directly sheared, so that the effects of easiness in operation and high positioning precision are achieved. Drawings The utility model is further described below with reference to the accompanying drawings: FIG. 1 is a front view of the present utility model; FIG. 2 is a side view of the present utility model; In the figure, 1, a sample suction needle, 2, a depth fixing clamping block, 3, a hoop, 4, an elastic sheet, 5, a separation sheet, 201, a groove, 401 and a bulge. Detailed Description For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. The technical scheme of the utility model is described in detail below by specific examples. The following specific embodiments may be combined with or replaced with each other according to actual situations, and the same or similar concepts or processes may not be described in detail in some embodiments.
