Technical Field

[0001] The utility model relates to the technical field of test instruments, in particular to a placement rack for water bath heating. Background Art

[0002] Water bath heating is a common heating method used in pharmaceutical test preparation and testing. Conventional water bath heating uses a floating plate or a storage rack to secure test tubes, beakers, and other containers during heating. Since commonly used test tubes and beakers come in a wide variety of capacities and sizes, ensuring container stability is crucial. While the aforementioned floating plate effectively secures the container, boiling water at temperatures above 100°C can affect the container's stability. Furthermore, the aforementioned storage rack also suffers from poor stability. Utility Model Content

[0003] The utility model provides a placement rack for water bath heating, which solves the above-mentioned deficiencies in the prior art and the problem of poor fixing stability of the heating container, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

A nut is engaged with the upper end of the connecting rods through a thread. The nut is located on the upper side of the upper plate. Multiple circular holes are formed on the upper plate. Multiple pairs of waist-shaped holes are formed on the upper plate. Each pair of waist-shaped holes is located on one side of the circular hole. A movable rod is inserted into the waist-shaped hole. The lower end of the movable rod is engaged with the lower plate through a thread. A clamping arm is provided at the upper end of the movable rod. The clamping arms are brought close to each other to limit the circumference of a container placed in the circular hole, thereby ensuring the stability of the container after placement. Furthermore, the bottom of the container is supported by the base plate, further enhancing the stability of the container after placement.

[0006] Furthermore, in order to level the entire placement rack, four supporting legs are threadedly engaged at the four corners of the bottom plate.

[0007] Furthermore, in order to increase the supporting area of ​​the lower end of the supporting leg and improve the stability after placement, the cross-section of the supporting leg is T-shaped.

[0008] Furthermore, in order to reduce the buoyancy of the bottom plate when the bottom plate is placed or used, holes are opened in the bottom plate.

[0009] Furthermore, in order to reduce the contact area between the bottom plate and the container and improve the water bath heating effect, a plurality of support rods are provided on the bottom plate, and the circular holes and the support rods are in a one-to-one correspondence, and the circular holes and the corresponding support rods are coaxially arranged.

[0010] Furthermore, in order to further reduce the contact area between the support rod and the container, the upper end of the support rod is provided with an arc-shaped structure.

[0011] Furthermore, in order to facilitate the placement and removal of containers and the placement rack, an L-shaped plate is provided at the upper end of the connecting middle rod at the same end, and a concave rod is provided at the outer end of each pair of L-shaped plates.

[0012] Furthermore, in order to lock the state of the clamping arm, a movable pin is provided on the lower plate, and the upper end of the movable pin is fixed to the outer end of the clamping arm. A spring is sleeved on the movable pin, and the spring is located between the lower plate and the clamping arm. The movable rod is passed through the clamping arm, and a circular sleeve is sleeved on the movable rod. The lower end of the circular sleeve is fixed to the clamping arm, and the upper end of the circular sleeve is provided with an upper convex arc plate. The upper end of the movable rod is provided with a swing plate, and a lower push rod is provided on the lower walls of both ends of the swing plate. The lower end of the lower push rod acts on the upper end of the circular sleeve, and a T-shaped rod is inserted into the outer end of the swing plate, and the upper end of the T-shaped rod is provided with a connecting plate. The lower wall of the connecting plate is provided with a T-shaped slot, the upper end of the T-shaped rod is passed through the T-shaped slot, and the upper end of the T-shaped rod is engaged with a locking nut through a thread, and the locking nut is located on the lower side of the connecting plate.

[0013] Furthermore, in order to facilitate the movement of the connecting plate, a holding rod is provided on the connecting plate.

[0014] The advantages of the above technical solution are:

[0015] The utility model can stably support the container and support it with a smaller contact area, thereby improving the heating effect without affecting the support stability. At the same time, it can also stably limit the container. BRIEF DESCRIPTION OF THE DRAWINGS
