Abstract
The utility model provides a positive and negative support of placing test tube, this support of has a base of a disc, is equipped with a pipy arch of circle at the mid portion of base, bellied center open have one with half ball grooves of test tube bottom matching, in the bottom of recess, be equipped with a round hole that matches with the bracing piece, be equipped with annular aqua storage tank around the boss, for curved wall that shelters from around the aqua storage tank, this positive and negative support of placing test tube simple structure, forward or the reverse test tube of placing can dry fast and can store water stain that the test tube flowed down to the test tube after the washing as required.
Description
Technical field
This utility model relates to the device of a kind of holding test tubes, the bearing of especially a kind of positive and negative holding test tubes.
Background technology
Test tube is the instrument that laboratory is common, it is possible to carry out the transfer of liquid reagent, can also serve as the reaction vessel of a small amount of reagent. The instrument of common holding test tubes is test tube rack, it is a shelf with multiple circular holes coordinated with test tube, this test tube rack generally can only just put test tube, and placement can not be swung to, this kind of test tube rack is unfavorable for the water rapid airing inside and outside firm washed test tube, and the water capacity dripped of test tube is easily made dirty desktop, therefore, exploitation a kind of can forward and reverse can holding test tubes, and the test tube placement device that can store the water that washed test tube flows down is particularly significant.
Summary of the invention
In order to overcome current test tube laying state single, not easily dry after washing and easily make dirty desktop problem, this utility model provides the bearing of a kind of positive and negative holding test tubes, the seat structure of this positive and negative holding test tubes is simple, can holding test tubes forward or backwards as required, for the test tube energy rapid airing after washing and can store that test tube flows down water stain.
This utility model solves its technical problem and be the technical scheme is that the bearing of this positive and negative holding test tubes, including: base, support bar; The bearing of this positive and negative holding test tubes has a discoidal base, and the mid portion at base is provided with the projection of a circular tube shaped, and protruding center has a hemispherical groove mated with test tube bottom; In the bottom of groove, it is provided with a circular hole mated with support bar; At the aqua storage tank being formed around annular of boss, the surrounding of aqua storage tank is the shelter wall of arc.
During use, when test tube is just put, will be placed in bottom test tube in hemispherical groove; When the test tube after washing needs to be inverted, being inserted by support bar in bottom portion of groove circular hole, be then upside down on support bar by test tube, the aquiform stool after washing can flow in aqua storage tank.
The beneficial effects of the utility model are: the seat structure of this positive and negative holding test tubes is simple, it is possible to holding test tubes forward or backwards as required, for the test tube energy rapid airing after washing and can store that test tube flows down water stain.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the structural representation of the bearing of positive and negative holding test tubes.
In Fig. 1,1. base, 2. support bar.
Detailed description of the invention
In Fig. 1, the bearing of positive and negative holding test tubes, including: base 1, support bar 2; The bearing of this positive and negative holding test tubes has a discoidal base 1, and the mid portion at base 1 is provided with the projection of a circular tube shaped, and protruding center has a hemispherical groove mated with test tube bottom; In the bottom of groove, it is provided with a circular hole mated with support bar 2; At the aqua storage tank being formed around annular of boss, the surrounding of aqua storage tank is the shelter wall of arc.
During use, when test tube is just put, will be placed in bottom test tube in hemispherical groove; When the test tube after washing needs to be inverted, being inserted by support bar 2 in bottom portion of groove circular hole, be then upside down in by test tube on support bar 2, the aquiform stool after washing can flow in aqua storage tank.
