[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment: a multi-hole plate heating carrier, including an electric heating plate 1, the electric heating plate 1 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The electric heating plate 1 can control the heating temperature. The upper surface of the electric heating plate 1 is provided with a quick-release component, and the quick-release component includes a slot 402. The inner wall of the slot 402 is plugged with a plug rod 43. The slot 402 and the plug rod 43 are provided with three groups, which are respectively located at the left front, left rear and right rear triangles of the upper surface of the electric heating plate 1. The upper surface of the plug rod 43 is fixedly connected to the multi-hole plate body 2, and the multi-hole plate body 2 and the electric heating plate 1 The upper surface of the porous plate body 2 is made of aluminum, which has good thermal conductivity and can ensure the utilization rate of heat. A positioning component is provided on the upper surface of the porous plate body 2, which can clamp and fix the test tube that needs to be heated. The positioning component includes a placement groove 301, and the test tube is inserted into the placement groove 301. The aperture of the placement groove 301 is relatively large, so that a large test tube can also be inserted. A support ring 32 is fixedly connected to the upper surface of the porous plate body 2, and a positioning ring 31 is threadedly connected to the outer wall of the support ring 32. When the positioning ring 31 rotates, it will slide longitudinally along the outer wall of the support ring 32. The front surface of the support ring 32 is penetrated and slidably connected with a positioning block 33, and the positioning block 33 slides in the front and rear directions.

[0031] Reference Figure 1 , Figure 4 The positioning assembly also includes a clamping plate 36 , and the inner wall of the support ring 32 is elastically connected to a pressing block 34 via a compression spring 35 .

[0032] Reference Figure 1 - Figure 3 The quick-release assembly also includes a card slot 401, which is opened at the right front corner of the upper surface of the electric heating plate 1. The inner wall of the porous plate body 2 is elastically connected to the rotating shaft 41 through a torsion spring 44. The top of the rotating shaft 41 is set to be convex, and the bottom end of the rear surface of the rotating shaft 41 is fixedly connected to a card block 42. When the rotating shaft 41 rotates, it will drive the card block 42 to move, and the direction of the card block 42 will change.

[0033] Reference Figure 1 - Figure 3 The slot 401 is opened on the upper surface of the electric heating plate 1, and the bottom end of the slot 401 is opened in a circular ring shape. The front side of the top opening of the slot 401 is square, and the back side is arc-shaped. The block 42 can be inserted from the square direction. One end of the torsion spring 44 is fixedly connected to the left surface of the rotating shaft 41, and the other end of the torsion spring 44 is fixedly connected to the inner wall of the left side of the porous plate body 2. When the rotating shaft 41 rotates, the torsion spring 44 will be squeezed to generate a reaction force. The rotating shaft 41 is plugged into the inner wall of the slot 401, and the block 42 is plugged into the inner wall of the slot 401. Under the action of the torsion spring 44, when the block 42 and the slot 401 are plugged, they will not be aligned with the square opening of the top end of the slot 401. The rotating shaft 41 passes through and is rotatably connected to the upper surface of the porous plate body 2.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The slot 402 is opened on the upper surface of the electric heating plate 1, the placement groove 301 is opened on the upper surface of the porous plate body 2, and the placement groove 301 is opened in multiple groups and distributed in an array. The support ring 32 is fixed at the placement groove 301, and the lower surface of the positioning ring 31 is provided with a protrusion, and the upper surface of the positioning block 33 is set as an inclined surface. When the positioning ring 31 moves downward, it will squeeze the inclined surface of the positioning block 33. A threaded groove is opened on the upper position of the outer wall of the support ring 32. The thread lead angle of the threaded groove is less than five degrees, which has a self-locking effect. When the rotation stops, the stability of the device can be maintained.

[0035] Reference Figure 1 , Figure 4 The front surface of the clamp 36 is fixedly connected to the rear surface of the positioning block 33, and the positioning block 33 and the clamp 36 will move synchronously. The rear surface of the clamp 36 is set to an arc surface, which can better fit the outer wall of the test tube and ensure stability during clamping. The left surface of the pressing block 34 is fixedly connected to the right surface of the positioning block 33, and the positioning block 33 and the pressing block 34 will also move synchronously.

[0036] Reference Figure 1 , Figure 4 The pressure block 34 is slidably connected to the inner wall of the support ring 32, one end of the compression spring 35 is fixedly connected to the rear surface of the pressure block 34, and the other end of the compression spring 35 is fixedly connected to the inner wall of the rear side of the support ring 32. When the pressure block 34 moves backward, it will squeeze the compression spring 35 to generate a reaction force.

[0037] Reference Figure 1 , Figure 4 There are multiple groups of positioning blocks 33, pressure blocks 34, compression springs 35, and clamps 36. The multiple groups of positioning blocks 33, pressure blocks 34, compression springs 35, and clamps 36 are arranged in a circular array with the center of the support ring 32 as the origin. The test tube can be clamped and fixed from multiple directions, ensuring that the test tube remains centered and ensuring stability during clamping.

[0038] Working principle: When the device is used, first, the test tube to be heated is passed through the support ring 32 and inserted into the placement groove 301. When the lower surface of the test tube contacts the upper surface of the electric heating plate 1, the positioning ring 31 is rotated to move the positioning ring 31 downward. The downward moving positioning ring 31 will squeeze the inclined surface of the positioning block 33. The inclined surface of the positioning block 33 will be squeezed and move toward the center of the support ring 32. When the positioning block 33 moves, it will drive the pressing block 34 and the clamping plate 36 to move synchronously. When the pressing block 34 moves toward the center of the support ring 32, it will squeeze the compression spring 35 to generate a reaction force. When the clamping plate 36 moves toward the center of the support ring 32, it will clamp the test tube. When the clamping plate 36 completes fixing the test tube, the positioning ring 31 is released. The self-locking effect of the threaded groove can keep the device stable and ensure the stability of the test tube clamping. Then the electric heating plate 1 is started to heat the test tube.

[0039] After heating is completed, the test tube needs to be removed. When removing it, first turn off the electric heating plate 1, then rotate the positioning ring 31 in the opposite direction to move the positioning ring 31 upward, and the positioning ring 31 moving upward will release the squeezing of the inclined surface of the positioning block 33, and the reaction force of the compression spring 35 will push the pressing block 34, the positioning block 33 and the clamping plate 36 to move toward the surroundings of the support ring 32, and the clamping plate 36 will separate from the test tube to release the clamping of the test tube, and then the test tube can be removed.

[0040] When the porous plate body 2 needs to be disassembled from the electric heating plate 1 for replacement or cleaning, the rotating shaft 41 is first rotated to drive the block 42 to rotate. When the block 42 and the square of the opening of the card slot 401 are aligned, the porous plate body 2 is moved upward, the plug rod 43 is disengaged from the slot 402, the rotating shaft 41 and the block 42 are disengaged from the card slot 401, and the porous plate body 2 is disassembled. After cleaning, the rotating shaft 41 is rotated to align the block 42 and the square of the opening of the card slot 401, and then The rotating shaft 41 and the block 42 are inserted into the card slot 401, and the insertion rod 43 and the slot 402 are plugged in. When the rotating shaft 41 rotates, it will also squeeze the torsion spring 44 to generate a reaction force. When the rotating shaft 41 and the block 42 are plugged into the card slot 401, the block 42 will be located at the bottom ring of the card slot 401. Driven by the reaction force of the torsion spring 44, the rotating shaft 41 will rotate and the block 42 will move. At this time, the upper surface of the block 42 will be blocked, and the porous plate body 2 will be installed on the electric heating plate 1.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
