Description

Technical Field

[0001] The utility model relates to the technical field of water bath pots, in particular to a water bath pot for food safety testing. Background Art

[0002] At present, constant temperature water bath is an essential tool for scientific research in the fields of biology, environmental protection, medicine, health, chemical laboratories and fine chemical analysis. Food safety testing is no exception. Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators.

[0003] In the prior art, for example, the patent application with the authorization publication number CN216573180U and the authorization publication date 2022-05-24, entitled "An Electric Constant Temperature Water Bath for Food Safety Testing", sets a constant temperature water bath body, a fixing plate, a square block, a positioning groove, a positioning block, a square groove, a clamping mechanism, a clamping groove and a transmission mechanism for coordinated use, and then rotates the rotating rod, and then places the fixing plate into the inner cavity of the constant temperature water bath, and finally releases the rotating rod to complete the installation, thereby achieving the effect of easy fixation, and solving the problem that the fixing plate inside the existing constant temperature water bath cannot be fixed to it. During the experiment, the fixing plate moves with the boiling water flow, causing the glass equipment containing the test food to break, thereby causing the test to be terminated, which brings unnecessary trouble to the user;

[0004] During the actual use of the above device, the fixed plate is fixed in the pot, and the distance between the cover plate and the fixed plate remains unchanged, so that the height range of the container that can be detected is fixed, which is not very applicable. In addition, the glassware containing the food to be tested is located on the fixed plate. When it needs to be taken out for experiment after heating, it is easy to get burned due to the high temperature of the water bath pot.

[0005] Therefore, we propose a water bath for food safety testing to solve the above problems. Utility Model Content

Inside the upper end of the water bath body, a frame is provided, and a limiting mechanism is installed between the frame and the water bath body. The frame moves up and down inside the water bath body through the limiting mechanism. A fixing plate is slidably installed in the middle of the frame, and a threaded rod is threadedly connected to the middle of the fixing plate. Moreover, the threaded rod is installed by bearings in the middle of the frame;

[0010] On the front and back sides of the left end of the water bath body, guide plates are fixedly installed. On the outer side of the left end of the water bath body, a "C"-shaped movable rod is slidably installed. The middle parts of both ends of the movable rod are respectively slidably installed inside the two guide plates. Moreover, a driving mechanism is installed between the movable rod and the frame, and the driving mechanism is used to drive the frame to move upward.

[0011] Furthermore, a positioning block is slidably installed inside the upper end of the guide plate, and a compression spring is connected between the positioning block and the guide plate.

[0012] Through the above technical solution, when the positioning block faces the positioning groove, the positioning block can extend into the positioning groove under the action of the compression spring to fix the moved movable rod.

[0013] Furthermore, positioning grooves that are concavo-convexly matched with the bottom end of the positioning block are opened on the upper sides of both ends of the movable rod, and a handle is fixedly installed in the middle of the left side of the movable rod.

[0014] Through the above technical solution, the movable rod can be pulled to move through the handle.

[0015] Furthermore, the driving mechanism includes two driving plates respectively fixedly installed at both ends of the movable rod. A stress plate is attached to the side of the driving plate, and the two stress plates are respectively installed on the front and back sides of the frame. Moreover, the stress plate is trapezoidally designed.

[0016] Through the above technical solution, the driving plate can drive the stress plate to move.

[0017] Furthermore, a fixing mechanism for fixing test tubes is installed inside the fixing plate. The limiting mechanism includes a guide ring fixedly installed on the side of the frame. The guide ring slides up and down on the outside of the guide rod, and the guide rod is fixedly installed inside the water bath body.

[0018] Through the above technical solution, the fixing plate can move upward under force under the guidance of the limiting mechanism.

[0019] Furthermore, the side of the fixing plate is attached to the side wall of the frame.

[0020] Through the above technical solution, after the threaded rod is rotated, the fixing plate can move up and down to be adjusted according to the height of the test tube.

[0021] 3. Beneficial effects:

The specific contents are as follows:

[0023] (1) After heating is finished, the cover is removed from the water bath body, and then the movable rod is pulled by the handle to move to the left inside the guide plate, and the driving plate installed at the end of the movable rod moves accordingly. During the displacement of the driving plate, the frame is driven to move upward inside the water bath body by the contact with the force-bearing plate until the positioning groove is opposite to the positioning block. The positioning block extends into the positioning groove under the action of the pressure spring to fix the movable rod after it moves, so that the test tube installed on the fixing plate can be extracted from the water bath body to avoid scalding.

[0024] (2) When adjustment is required according to the specifications of the test tube, the threaded rod is rotated, and the fixing plate threadedly sleeved on the outside of the threaded rod can move up and down on the frame by virtue of the fit between the fixing plate and the frame. Then the fixing plate fixes the test tube through the fixing mechanism to adapt to different test tube heights, thereby improving applicability. BRIEF DESCRIPTION OF THE DRAWINGS
