An experimental thermostatic shaking test tube fixing rack

Abstract

The utility model discloses a kind of experimental constant-temperature oscillation test tube fixing frame, it is related to experimental equipment technical field, including: two clamps one, for parallel arrangement, its upper and lower are uniformly provided with notched; clamp two, between two described clamps one, it is elastically slidably arranged, it is also provided with described notched on it, the notched on the clamp one and the notched lateral wall on the clamp two form test tube clamping area;The test tube in this scheme is placed, will not directly fall into the bottom of clamping area, can be first fallen on step, after transverse moving clamp two, can make test tube reach the bottom, by twice operation, reduce the speed of test tube falling, avoid test tube because of rapid falling and the violent collision of clamping area bottom, effectively protect test tube from being damaged, only need to insert test tube into the notched of clamp one in upper side during use, it is simple and quick to operate.

Claims

1. A test tube holder for laboratory use with constant temperature shaking, characterized in that, include: The two clamps (1) are set in parallel, and slots are evenly provided on their upper and lower sides; The second clamp (2) is elastically slidably disposed between the two first clamps (1), and the groove is also provided thereon. The groove on the first clamp (1) and the groove sidewall on the second clamp (2) form a test tube clamping area. In the case where the test tube is not clamped, the vertical projection of the groove on clamp one (1) and the groove on clamp two (2) is smaller than the cross-section of the test tube. Clamp two (2) separates the two corresponding grooves on clamp one (1).

2. The experimental constant-temperature shaking test tube holder according to claim 1, characterized in that: A crossbar (11) is fixedly installed on one side of each of the two clamping plates (1), and a connecting frame (13) is fixedly installed on the other side of the two clamping plates (1). A sliding frame (21) is fixedly installed on one side of the clamping plate (2). The sliding frame (21) is sleeved on the two crossbars (11), and a spring (12) is also provided on the crossbars (11).

3. The experimental constant-temperature shaking test tube holder according to claim 2, characterized in that: One end of the sliding frame (21) is slidably inserted into the connecting frame (13), and the connection between the sliding frame (21) and the connecting frame (13) is at the same height as the clamping plate (2).

4. The experimental constant-temperature shaking test tube holder according to claim 1, characterized in that: The cross-section of the slot is set as an elongated strip, and the two ends of the elongated strip are set as arcs.

5. The experimental constant-temperature shaking test tube holder according to claim 4, characterized in that: The diameter of the arc at both ends of the groove is equal to the diameter of the test tube, and the width of the groove is also equal to the diameter of the test tube.
