Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1:

the utility model provides a simple and easy universal test tube anchor clamps that vibrate, includes test tube anchor clamps 1 and fixed plate 2, fixed plate 2 passes through bolted connection on the installation carrier, and the installation carrier is the used machine that vibrates in laboratory.

As shown in fig. 1 and 2, the test tube holder 1 is of a regular tetrahedron shape, and the test tube holder 1 is provided with a receiving hole 3, and the diameter of the receiving hole 3 is larger than the outer diameter of the test tube. The accommodating hole 3 is a blind hole, the inner side wall of the accommodating hole 3 is twisted with threads, and the accommodating hole 3 is connected with a gland 4 in a threaded manner. Open on the fixed plate 2 and have a sliding tray 5, sliding tray 5 is provided with threely about the central symmetry of fixed plate 2, and sliding connection has positioning seat 6 in sliding tray 5, and test tube anchor clamps 1 are placed on fixed plate 2 for one of them face of test tube anchor clamps 1 pastes tightly on fixed plate 2, adjusts positioning seat 6 and supports tightly at the lateral wall of test tube anchor clamps 1.

As shown in fig. 1 and 2, the worker seals the open end of the test tube filled with the liquid, then inserts the test tube into the accommodating hole 3, and takes up the pressing cover 4 to screw into the accommodating hole 3, so that the pressing cover 4 is pressed against the upper end of the test tube, thereby stably placing the test tube in the test tube holder 1. Then the staff adjusts positioning seat 6 and removes to the direction of keeping away from fixed plate 2 center, places test tube fixture 1 on fixed plate 2, then adjusts positioning seat 6 and moves to the direction that is close to test tube fixture 1 for test tube fixture 1 is fixed on fixed plate 2 steadily.

As shown in fig. 2, in order to reduce the shaking of the test tube in the test tube holder 1 during the shaking process. The bottom of the accommodating hole 3 is arc-shaped, the lower part of the gland 4 is provided with a pressure hole 7, the upper part of the gland 4 is fixedly connected with a handle 8, and the handle 8 and the gland 4 are integrally formed. The staff places the test tube in accommodation hole 3, and the bottom of test tube is hugged closely in accommodation hole 3's bottom, and the open end alternate of test tube is in pressing hole 7, then screws up gland 4 and makes the test tube support tightly in accommodation hole 3. The setting of handle 8 can improve the convenience that the staff picked up gland 4.

As shown in fig. 1 and 3, because positioning seat 6 is in sliding connection in sliding groove 5, when the shock test is reduced, positioning seat 6 slides along sliding groove 5, resulting in unstable positioning of test tube fixture 1, the cross-section that sets up sliding groove 5 is "T" shape, and positioning bolt 9 is worn to be equipped with on positioning seat 6, and positioning bolt 9 runs through positioning seat 6 and contradicts at the tank bottom of sliding groove 5. After the test tube fixture 1 is placed on the fixing plate 2, the adjusting and positioning seat 6 is tightly abutted to three side faces of the test tube fixture 1, and then the positioning bolt 9 is screwed down and tightly abutted to the bottom of the sliding groove 5, so that the position of the positioning seat 6 is fixed.

The specific implementation process comprises the following steps: first, the operator seals the open end of the test tube filled with liquid, then inserts the test tube into the receiving hole 3, picks up the gland 4 and screws into the receiving hole 3, so that the gland 4 is pressed against the upper end of the test tube. At this moment, the staff utilizes the bolt to install fixed plate 2 on shaking the machine, then places test tube fixture 1 in the middle of three positioning seat 6, adjusts positioning seat 6 and supports tightly in the three side of test tube fixture 1, realizes the location to test tube fixture 1. At this moment, the staff opens the switch of shaking the machine, and the liquid in the test tube shakes along with shaking the machine, shakes after a period of time, and the staff can change the direction of test tube anchor clamps 1, realizes the vibration of different angles for the liquid phase in the test tube obtains abundant mixture.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
