Description

A take out pole accessory for liquid extraction sampling

Technical Field

The utility model belongs to liquid sampling detects the field, concretely relates to take out pole accessory for liquid extraction sampling.

Background

No matter whether new crown sampling detects or sewage detects, still chemical liquid detects, all involves and need carry out the extraction sampling to liquid, and the extraction sampling just need use the pole accessory of taking out.

The existing drawing rod accessory technology is monopolized abroad, a drawing rod and an accessory head are integrally formed abroad, but the design has high requirements on a mould, the precision of the mould needs to be improved due to the small size of the accessory, so that the manufacturing cost is correspondingly improved, and the existing domestic drawing rod is not designed in a targeted manner, such as a drawing type liquid sampling device (publication No. CN 207649957U) in the patent, which discloses a sampling design in the general sense, the drawing rod is extracted by applying force through a drawing plate, and the drawing plate is provided with a through hole which can facilitate tying a drawing rope for indirect force application. The first problem that this design exists is that need artifical supplementary realization, has not realized the automation yet, and is inefficient, and although disclosing the design of carrying the arm-tie, but specifically how to keep the structural stability of carrying the arm-tie and pull pole, not disclosing, and according to the integration of prior art, still generally adopt the design of carrying the arm-tie and pull pole integration, if the pull board and the pull pole of beating the syringe are just as an organic whole, the required precision is high, and the cost of manufacturing is relatively high.

SUMMERY OF THE UTILITY MODEL

The technical problem is as follows: the utility model discloses a solve current pole implementation mode of taking out and fall behind, take out pole and the first integration design required precision of accessory high, the problem with high costs of manufacturing.

The technical scheme is as follows: the utility model adopts the following technical scheme:

the utility model provides a take out pole accessory for liquid extraction sampling, includes accessory head that can dismantle each other, takes out the pole and cup joints the rubber sleeve of taking out the pole and keeping away from the one end of accessory head, the accessory head is plastics accessory head, it takes out the pole for the pottery to take out the pole, the accessory head is circular with the cross-section of taking out the pole along length direction, and the one end of accessory head length direction forms and supplies to take out pole male slot, and the outer wall of the nearly length direction other end of accessory head rest forms the block groove that can extract the sampling device block with liquid, the circumference wall of accessory head slot forms a plurality of conical archs towards the slot center, and the conical archs extend and form the prism along the length direction of slot, the pointedness of cone and the pottery that inserts in the slot take out pole interference fit for the prismatic pointe of cone is extruded and is formed the laminating plane.

The pole can be taken out through design accessory head and pottery and can be dismantled the connection for two accessories all can be produced alone and make, eliminate foreign technology blockade, design this scheme, and to single production, it is simpler to produce manufacturing, nevertheless in order to realize the firm connection between two accessories, be the working of plastics through the accessory head, take out the pole for the prerequisite of ceramic part under, there is the prismatic and pole interference fit of taking out of taper in the design slot, realize stable connection between them.

In the production and manufacturing process, the ceramic pull rod is firstly produced, then the accessory head is directly prepared on the periphery of the ceramic pull rod through thermosetting plastics, and then the accessory head is enlarged after curing, so that the ceramic pull rod is in interference fit with the accessory head.

Furthermore, the part of the drawing rod inserted into the slot forms a clamping groove which is inwards sunken along the circumferential direction of the drawing rod, and the pointed end part of the conical prism in interference fit with the drawing rod is clamped in the clamping groove.

Through the design joint groove for the sharp head part of the tapered prism of the accessory head after solidification can insert in the joint inslot, and the cooperation of interference fit's partial sharp head part, form and prevent that the accessory head from taking place relative slip's structure with taking out the pole in length direction.

Furthermore, the diameter of an inner ring formed by the surrounding of the pointed parts of the conical prisms in the slot is smaller than that of the pull rod.

Further, the diameter of the slot is larger than that of the draw rod.

Providing a condition in which the tip portion of the tapered prism can be inserted into the catching groove.

Furthermore, the clamping groove is far away from the upper edge of the pumping rod to form a clamping bulge which can be clamped on the liquid extraction sampling device.

Furthermore, a U-shaped groove which can be clamped into the clamping protrusion from one side is arranged on a manipulator which can move up and down of the liquid extraction and sampling device.

Further, the thickness of the clamping protrusion is smaller than the thickness of the U-shaped groove.

The purpose of this is in order to make the pole of taking out can take place a bit angular deviation in vertical direction, prevents that the outer wall rubber sleeve of the pole of taking out that does not totally counterpoint from taking place excessive friction with the outer wall of being taken out, destroying the rubber sleeve.

Furthermore, the head of the draw-bar in the slot is also provided with a head bulge, and the bottom surface of the slot corresponding to the position of the head bulge is provided with a positioning groove matched with the head bulge.

The cooperation joint groove can accomplish better location to the length direction of taking out the pole and circumference, also can know simultaneously through observing whether the pole has accomplished the butt joint.

Has the beneficial effects that: compared with the prior art, the utility model has the advantages of it is following:

adopt the design scheme of the utility model, take out pole interference fit through class dentate taper prism and pottery, accomplish stable connection, improve and take out the stability that pole and accessory head are connected, abolished foreign technique blockade, and the manufacturing cost of this scheme of adoption is foreign one tenth, greatly reduced manufacturing cost.
