Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an adjustable water bath pot pipe rack. Background Art

[0002] The container or substance to be heated in a water bath is placed in another container filled with water, and the internal container is indirectly heated by heating the external water. The advantages of water bath heating include: stable temperature control. Due to the large specific heat capacity of water, water bath heating can provide a uniform and stable temperature environment for testing drugs in the laboratory for biochemical and physicochemical reactions in a water bath. In the prior art, there are many water baths that can realize temperature control. When a test tube or centrifuge tube is heated in a water bath, a tube rack needs to be set in the pot to clamp and fix the heated test tube or centrifuge tube. During the use of the water bath, due to the influence of factors such as the amount of water added and the consumption of water, it is difficult to control the height of the water level in the pot during actual use, so the height of the submerged reaction container is also difficult to control. The prior patent CN202823451U discloses a special test tube rack for a water bath, and there are protrusions corresponding to the grooves on both sides of the test tube support plate. The test tube support plate can slide up and down along the groove, so that the experimenter can adjust the height of the test tube support plate according to the water level of the water bath at any time. Although the above patent can adjust the height of the test tube support plate, this adjustment method has a height gradient and the adjustment options are very limited. In addition, once the test tube rack is placed in a water bath in the above solution, it is difficult to adjust it in the pot. Utility Model Content

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0012] See also Figure 1-2 The utility model provides a technical solution: an adjustable water bath pot tube rack, including a disc-shaped base 1 and a support plate 5. A plurality of evenly distributed support legs 10 are installed at the bottom of the base 1. The support legs 10 support the base 1 to reduce the contact area with the bottom of the pot. The support plate 5 is provided with a plurality of circular holes penetrating from top to bottom. The circular holes are of different sizes to accommodate centrifuge tubes or test tubes of different diameters. A vertical guide column 2 is fixedly installed in the middle of the upper side of the base 1. The guide column 2 is a square tube structure and an end cover is fixedly installed at the upper end. A screw rod 11 is rotatably connected to the middle of the end cover. The screw rod 11 axially penetrates the guide column 2 and the lower end is connected to the base 1. A hand wheel 3 is fixedly installed at the upper end of the screw rod 11.

[0013] The four sides of the guide column 2 are respectively provided with vertical long holes 6, and a matching slider 7 is slidably connected in the guide column 2. The four sides of the slider 7 are respectively provided with mounting arms extending from the long holes 6. A penetrating square hole is provided in the middle of the support plate 5, and the support plate 5 is sleeved on the guide column 2 through the square hole. The support plate 5 is fixedly connected to the mounting arm, and the screw rod 11 passes through the slider 7 up and down and is screwed thereto. The screw rod 11 is rotated by the hand wheel, and the screw rod 11 drives the slider 7 to slide up and down in the guide column 2, thereby synchronously driving the support plate 5 to move up and down to adjust the height.

[0014] The outer side of the base 1 is provided with three radial spokes evenly distributed along the circumference, each spoke correspondingly provided with a slot 9 extending radially inward, a matching plug block 4 is slidably connected in the slot 9, and a spring 8 is connected between the inner end of the plug block 4 and the bottom of the slot 9. The outer end of the plug block 4 is an arc surface, and the plug block 4 is made of high temperature resistant plastic material. The spring 8 applies an outward thrust to the plug block 4, so that the outer end of the plug block 4 is against the inner wall of the water bath pot to improve stability.

[0015] Working principle: When in use, place the tube rack in a water bath pot, and the plug block 4 on the outside of the base 1 can be pressed against the inner wall of the pot to prevent shaking due to the influence of bubbles when heated in the water bath. Tube containers can be inserted into the round holes on the support plate 5 for clamping. Turning the hand wheel 3 on the top can drive the support plate 5 to move vertically, thereby facilitating the adjustment of the height of hot water immersion according to test needs.
