Abstract
The utility model discloses a positioner for test tube, including being equipped with a plurality of lower extremes for the adapter of the test tube hole of circular conical surface, establishing test tube hole upper end through elastic claw with the fixed positioning fixture in test tube upper portion, be equipped with the round hole that the test tube hole on the adapter corresponds just is located fix positioning fixture fixes the clamp plate on the adapter above the positioning fixture. The utility model discloses a characteristics are with increasing positioning fixture between adapter and the test tube, through the upper portion of the fixed test tube of elastic claw on the positioning fixture, the lower extreme of the fixed test tube of conical surface in test tube hole forms the fixed mode to test tube two point location, can change along with test tube diameter size between the elastic claw, can solve the accurate positioning of different pipe diameter test tubes like this, can satisfy the manipulator and snatch the test tube and to the accurate requirement of position, be applicable to automatic centrifugal system, the test tube location that can extensively be used for various occasions simultaneously.
Description
Technical Field
The utility model belongs to centrifuge's adapter structure, concretely relates to a positioner for test tube.
Background
The centrifugal machine is used for separating matter, belongs to basic laboratory equipment and is used widely in life science, medicine, chemistry, environment protection and other fields. Along with the development of the market, the recruitment is more and more difficult and the manual operation is easy to make mistakes, so that all hospitals need a full-automatic system to replace the manual operation, and the efficiency is improved. The test tube on original adapter does not have the positioning fixture device, and the position size that repeatedly places is inaccurate, and like this the manipulator does not grab and gets, just so can not be applicable to on the automatic centrifugal system.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a be suitable for automatic work's positioner for test tube.
Realize the utility model discloses the technical scheme of purpose is:
the utility model provides a positioner for test tube, including being equipped with a plurality of lower extremes for conical surface's test tube hole's adapter, establishing test tube hole upper end through elastic claw with the fixed positioning fixture in test tube upper portion, be equipped with the round hole that test tube hole on the adapter corresponds just is located fix the clamp plate on the adapter with positioning fixture above the positioning fixture.
The positioning clamp comprises an annular body and inwards convex elastic claws which are uniformly arranged at the lower part of the annular body, the elastic claws of the positioning clamp are clamped in the hole of the test tube hole, the annular body is positioned at the end part outside the hole of the test tube hole, the pressing plate covers the annular body of the positioning clamp, and the positioning clamp is fixed on the adapter through screws.
Has the advantages that:
the utility model discloses a characteristics are with increasing positioning fixture between adapter and the test tube, through the upper portion of the fixed test tube of elastic claw on the positioning fixture, the lower extreme of the fixed test tube of conical surface in test tube hole forms the fixed mode to test tube two point location, can change along with test tube diameter size between the elastic claw, can solve the accurate positioning of different pipe diameter test tubes like this, can satisfy the manipulator and snatch the test tube and to the accurate requirement of position, be applicable to automatic centrifugal system, the test tube location that can extensively be used for various occasions simultaneously.
The technical scheme of the utility model is further explained in the following with the attached drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a plan view of the present invention.
Fig. 3 is a schematic structural view of the middle positioning fixture of the present invention.
In the figure:
1. an adapter; 101. a conical surface; 102. a test tube hole; 2. positioning a clamp; 201. an annular body; 202. an elastic claw; 3. pressing a plate; 4. a test tube; 5. and (4) screws.
Detailed Description
Referring to fig. 1-3, the positioning device for test tubes provided by the present invention comprises an adapter 1 provided with a plurality of test tube holes 102, a positioning fixture 2 and a pressing plate 3, wherein the lower end of the test tube hole 102 is a conical surface 101, the positioning fixture 2 comprises an annular body 201 and 4 inward convex elastic claws 202 uniformly arranged at the lower part of the annular body 201, and the pressing plate 3 is provided with a circular hole corresponding to the test tube hole 102 on the adapter 1; the opening of each test tube hole 102 is provided with a positioning clamp 2, an elastic claw 202 of the positioning clamp 2 is clamped in the opening of the test tube hole 102, the annular body 201 is positioned at the end part outside the opening of the test tube hole 102, the pressing plate 3 covers the annular body 201 of the positioning clamp 2, and the positioning clamp 2 is fixed on the adapter through a screw 5.
The utility model discloses during the use, the manipulator can place and snatch test tube 4 in adapter 1's test tube hole 102 is automatic, coordinates the operation of a whole set of automatic system. Test tube 4 passes the round hole of clamp plate 3 and the ring body 201 of positioning fixture 2 and inserts in adapter 1's test tube hole 102, and the lower extreme of test tube 4 and adapter 1's test tube hole 102 lower extreme circular conical surface 101 cooperation location, and the upper portion of test tube 4 and positioning fixture 2's elastic claw 202 cooperation location, and positioning fixture 2 is fixed on adapter 1 by clamp plate 3, and positioning fixture 2 takes off when can preventing that the manipulator from repeatedly snatching test tube 4, will form the fixed mode of two point location to test tube 4 like this.
