[0002] A water bath heating pot is a common laboratory heating equipment. Its main functions are as follows: 1. It can provide a temperature-stable heating environment, which is suitable for experimental operations that require precise temperature control; 2. Water can effectively disperse heat to avoid direct heating that may cause the sample to be burned or the container to be damaged; 3. The temperature range is wide. A water bath heating pot can generally provide a heating range from room temperature to 100°C to meet various experimental needs.

[0003] like Figure 1 As shown, the top of the water bath heating pot is provided with a plurality of lids 11. When the lids 11 are opened, the following tasks can be performed: placing a container in the pot body 12, or adding other reagents into the container, or stirring the sample in the container, or taking the container out of the pot body 12. The problem is that each lid 11 is independently provided, and the staff can only open the lids 11 one by one. After the tasks to be performed are completed, the staff still needs to cover the lids 11 one by one, which is too inefficient. Utility Model Content

[0009] Two lifting mechanisms are respectively arranged at both ends of the pot body, and a support plate is arranged on the top of the lifting mechanism to adjust the height of the support plate;

[0010] The linear travel mechanism is arranged on one of the support plates and is connected to one end of the rectangular frame, so as to enable the rectangular frame to move horizontally along the direction of the symmetry axis of the arc ring itself.

[0011] Furthermore, a cover plate is provided on the top of the pot body, and a plurality of through holes are arranged in an array on the cover plate. A circle of steps is provided on the outer periphery of the top surface of each through hole. The lid covers the through hole and is supported on the steps.

[0012] Furthermore, it also includes a limit frame, the top surface of the limit frame is not higher than the bottom surface of the arc ring, and the end of the limit frame is fixedly connected to the support plate.

The lid 11 covers the through hole 14 and is supported on the steps 15 .

[0025] Specifically, Figure 2 , Figure 6 , Figure 7 As shown, the control frame 4 includes a rectangular frame 41 and 6 arc rings 42, and the 6 arc rings 42 are connected to the rectangular frame 41. The specific connection method is: three gaps are respectively disconnected on the two long sides of the rectangular frame 41, and an arc ring 42 is set at each gap. The bottom surface of the rectangular frame 41 is flush with the bottom surface of the arc ring 42. The 6 arc rings 42 are distributed in an array. The number and position of the arc rings 42 correspond to the cover 11. The arc ring 42 itself is axially symmetrical. The arc ring 42 includes The first ring 421 and the second ring 422, two straight plates 423 are arranged between the first ring 421 and the second ring 422, the end of the first ring 421 is tangent to the corresponding straight plates 423, a channel is formed between the two straight plates 423, the channel is connected to the second ring 422, the inner diameter of the second ring 422 is larger than the diameter of the convex plate 112, the second ring 422 is used to allow the convex plate 112 to pass through, the inner diameter of the first ring 421 is consistent with the diameter of the column 111, and the first ring 421 is used to cover the column 111.

[0026] Specifically, Figure 2 As shown, two lifting mechanisms 2 are respectively arranged at both ends of the pot body 12, and a support plate 21 is provided on the top of the lifting mechanism 2. The power source of the lifting mechanism 2 can be driven by a cylinder, an oil cylinder or a hydraulic cylinder to adjust the height of the support plate 21. The linear stroke mechanism 3 is arranged on one of the support plates 21, and the linear stroke mechanism 3 is connected to one end of the rectangular frame 41 to make the rectangular frame 41 move horizontally along the direction of the symmetry axis of the arc ring 42 itself.

[0027] There are many ways to implement the linear travel mechanism 3. This embodiment adopts the following methods: Figure 2-Figure 4 As shown, a guide block 22 is provided on the top of the support plate 21, and the guide block 22 is provided with a guide groove running through it. The end of the rectangular frame 41 is slidably matched with the corresponding guide groove. The linear travel mechanism 3 includes a motor 31, a gear 32 and a rack 33. The rack 33 is provided at one end of the rectangular frame 41, and the rack 33 is meshed with the gear 32. The motor 31 is provided at the bottom of the support plate 21, and the output shaft of the motor 31 passes through the support plate 21 and is connected to the gear 32.

[0028] exist Figure 3In this state, the covers 11 all cover the through holes 14, and the first ring 421 covers the pillars 111. Next, the arc ring 42 needs to release all the covers 11. For the convenience of description, Figure 3 The four directions are assumed to be front, back, left and right, respectively. The same applies to the following. The specific method is as follows: first, the motor 31 is used to drive the gear 32 to prompt the regulating frame 4 to move backward, and the second ring 422 stops when it moves to just below the convex plate 112, and then the lifting mechanism 2 is used to move the support plate 21 upward, so that the linear stroke mechanism 3 and the regulating frame 4 move upward, and all the covers 11 continue to cover the through hole 14; when it is necessary to open individual covers 11, the staff manually opens the corresponding cover 11; when it is necessary to open all the covers 11 at the same time, the lifting mechanism 2 is used to move the support plate 21 downward, so that the linear stroke mechanism 3 and the regulating frame 4 move downward, and when the convex plate 112 passes through the second ring 422, the support plate 21 stops moving downward, and then the motor 31 is used to drive the gear 32 to prompt the regulating frame 4 to move forward until the first ring 421 covers the column 111, and finally the lifting mechanism 2 is used to move the support plate 21 upward, so that the regulating frame 4 and all the covers 11 move upward.

[0029] In order to make the first ring 421 fit the pillar 111 more smoothly, and also to make the arc ring 42 release the cover 11 smoothly, the present embodiment adopts the following measures: Figure 2-Figure 4 As shown, the device also includes a limit frame 5, the top surface of the limit frame 5 is not higher than the bottom surface of the arc ring 42, the limit frame 5 will not interfere with the forward and backward movement of the regulating frame 4, the end of the limit frame 5 is fixedly connected to the support plate 21 or fixedly connected to the guide block 22, when the regulating frame 4 moves downward and the protruding plate 112 just passes through the second ring 422, the bottom surface of the limit frame 5 is close to the top surface of the cover 11.

[0030] The principle is as follows: after the arc ring 42 releases all the covers 11, when all the covers 11 need to be opened at the same time, the lifting mechanism 2 is used to move the support plate 21 downward to move the linear travel mechanism 3 and the regulating frame 4 downward. When the convex plate 112 passes through the second ring 422, the support plate 21 stops moving downward. At this time, the bottom surface of the limit frame 5 is close to the top surface of the cover 11. The limit frame 5 presses the cover 11 to increase the stability of the cover 11. Then the motor 31 is used to drive the gear 32 to move the regulating frame 4 forward until the first ring 421 covers the column 111. During the forward movement of the regulating frame 4, the limit frame 5 always remains stationary. Finally, the lifting mechanism 2 is used to move the support plate 21 upward, thereby moving the regulating frame 4 and all the covers 11 upward.

[0031] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
