[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-2 The test tube heater shown includes a base 1, with a heating block 2 fixedly connected to the top of the base 1. The heating block 2 is made of a heat-conducting material. The base 1 has a heating element inside for heating the heating block 2. The heating block 2 has multiple tube grooves 3 arranged in a matrix. A movable plate 4 is located directly above the heating block 2. The movable plate 4 has multiple through holes 6 that cooperate with the tube grooves 3. The diameter of the through holes 6 is the same as that of the tube grooves 3. Multiple limiting posts 5 are fixedly connected to the bottom of the movable plate 4. The top of the base 1 has multiple limiting holes 9 that match the limiting posts 5. The limiting posts 5 are inserted into the limiting holes 9. The movable plate 4 is made of a heat-insulating material, and a pair of symmetrical handles 8 are fixedly connected to the top of the movable plate 4. The surface area of ​​the movable plate 4 is larger than that of the heating block 2, and the movable plate 4 can completely cover the surface of the heating block 2.

[0019] The test tube heater is a device for heating chemical substances in test tubes, mainly used for heating solutions or substances in test tubes in laboratories to promote chemical reactions or perform material heating treatment. The heater mainly includes a base and a heating block. The heating block is made of heat-conducting material. A plurality of tube slots for inserting test tubes are formed on the heating block. The base is internally provided with a heating element for heating the heating block.

[0020] In the scheme, the user can first insert the test tube into the plurality of through holes 6. The test tube enters the tube slot 3 through the through hole 6. The user starts the heating element in the base 1 to heat the heating block 2, and then heats the test tubes in the plurality of tube slots 3. During the process of taking and placing the test tube, the handle 8 is always covered on the top end of the heating block 2, and the user's hand cannot contact the heating block 2, which fundamentally avoids the possibility of scalding. At the same time, the user can pull a pair of handles 8 upwards to make the movable plate 4 drive the plurality of limiting columns 5 to slide upwards in the limiting hole 9, and then pull out all the test tubes from the heating block 2 at one time, and quickly cut off the heating of the test tube by the heating block 2.

[0021] As shown in Figure 3 The edge position of the upper side of the plurality of through holes 6 is provided with a pair of symmetrical support plates 7. The support plates 7 are arranged around the through holes 6, and the support plates 7 are arranged in an arc shape matched with the through holes 6. The plurality of support plates 7 are fixedly connected with the movable plate 4.

[0022] In the scheme, the plurality of support plates 7 support the test tube, so that the top end of the test tube is higher than the surface of the movable plate 4 by a certain distance. The raised part is convenient for the user to place and take the test tube.

[0023] The inner wall of the limiting hole 9 is provided with a damping pad, which tightly abuts against the outer surface of the limiting column 5.

[0024] In the scheme, the damping pad in the limiting hole 9 can play a damping effect between the limiting hole 9 and the limiting column 5, so that the user can hover after pulling up the movable plate 4, which is convenient for the user to place and take the test tube.

[0025] The specific implementation process is as follows:

[0026] In use, the user first inserts the test tubes into the plurality of through holes 6, with the top of the test tubes abutting against the pair of support plates 7, and the lower part of the test tubes entering the tube grooves 3 through the through holes 6, the user presses the movable plate 4 downward to cover the heating block 2, then the user starts the heating element inside the base 1 to heat the heating block 2, so that the test tubes in the plurality of tube grooves 3 are heated, after the heating is completed, the user pulls the handle 8 upward to drive the plurality of limiting columns 5 to slide upward in the limiting holes 9, thereby pulling out all the test tubes from the heating block 2 at one time, and quickly cutting off the heating of the test tubes by the heating block 2.

[0027] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
