[0030] A test stand for placement in a constant temperature bath according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 A test rack for placement in a constant temperature chamber according to an embodiment of the utility model includes a rack body 100 and a supporting assembly.

[0032] Among them, the frame body 100 includes an upper limit frame 110, a lower limit frame 120 and a connecting rod 130, the connecting rod 130 connects the upper limit frame 110 and the lower limit frame 120, and a storage cavity is formed between the upper limit frame 110 and the lower limit frame 120, and the storage cavity is used to accommodate the temperature-controlled items.

[0033] Therefore, when doing some physical and chemical tests, the items can be placed in a beaker, and then the beaker is placed in the storage cavity. Usually, in order to maintain the uniformity of the water temperature in the constant temperature bath, a stirrer or a water pump is used to agitate the water flow. At this time, the upper limit frame 110 and the lower limit frame 120 can limit the beaker to prevent the beaker from shaking up and down, ensuring that the beaker is in a suitable position in the constant temperature bath to ensure normal testing.

[0034] In some embodiments of the present invention, referring to Figure 2 The upper limit frame 110 includes a square frame 170, a first limit bar 180 and a second limit bar 190 disposed in the square frame 170, and the first limit bar 180 and the second limit bar 190 are distributed in a cross shape.

[0035] The first limiting strip 180 and the second limiting strip 190 can limit the temperature-controlled object to prevent the temperature-controlled object from leaving the accommodation chamber, ensure uniform water temperature in the accommodation chamber, and reduce the weight of the test stand.

[0036] In some embodiments of the present invention, the lower limit frame 120 is a flat plate having a plurality of water holes 210, and the water holes 210 are used to guide the liquid in the constant temperature bath into the receiving cavity, so that the water in the constant temperature bath can enter the receiving cavity from the water holes 210 to ensure that the water temperature in the receiving cavity is uniform.

[0037] In some embodiments of the present invention, four connecting rods 130 are provided, and the four connecting rods 130 are distributed at four corners of the flat plate, so that the temperature-controlled objects can be placed into the storage cavity from the side of the test rack.

[0038] Among them, the supporting assembly is provided with several, including a socket 140 and a telescopic rod device 150. The socket 140 is arranged at the bottom of the lower limit frame 120. The socket 140 is provided with a mounting hole 160 extending downward. The socket 140 is plugged into the telescopic rod device 150 through the mounting hole 160, and the telescopic rod device 150 can adjust its own length.

[0039] It can be understood that the telescopic rod device 150 can be inserted into the mounting hole 160 on the socket 140 so that the telescopic rod device 150 supports the frame 100. The telescopic rod device 150 can change its own length, and thus the height of the test frame can be changed to adapt to being placed in constant temperature baths of different depths, thereby improving the versatility of the test frame and eliminating the need to manufacture test frames of different specifications, thereby reducing manufacturing costs. At the same time, the telescopic rod device 150 can be removed from the mounting hole 160 on the socket 140. When stored, the space occupied by the test frame is reduced, making it convenient to store.

[0040] In some embodiments of the present invention, a support plate 220 is provided at one end of the telescopic rod device 150 away from the socket 140 , and the support plate 220 is used to abut against the bottom wall of the thermostatic bath.

[0041] Therefore, the support plate 220 increases the contact area between the test rack and the bottom wall of the constant temperature bath, so that the test rack is placed stably and is not easy to shake.

[0042] In some embodiments of the present invention, the telescopic rod device 150 includes a first tube body 230 and a second tube body 240 that are coaxially arranged. The first tube body 230 is located in the second tube body 240, and the second tube body 240 and the first tube body 230 can be relatively slidably arranged. One end of the first tube body 230 is inserted into the mounting hole 160. The telescopic rod device 150 also includes a locking structure, which is used to connect and fix the second tube body 240 and the first tube body 230.

[0043] Therefore, the second tube body 240 and the first tube body 230 can slide relative to each other to change the length of the telescopic rod device 150, and the second tube body 240 and the first tube body 230 are locked using a locking structure, so that the height of the test stand can be changed to adapt to being placed in a constant temperature bath of different depths.

[0044] In some embodiments of the present invention, referring to Figure 3 The locking structure includes a locking nut 250 and a sleeve 260. The locking nut 250 is threadedly connected to the outer surface of the second tube body 240. The sleeve 260 is sleeved on the first tube body 230 and is located on the inner side of the locking nut 250. The sleeve 260 can be elastically deformed to clamp the first tube body 230. The locking nut 250 is provided with an abutment portion 270. The sleeve 260 is provided with a convex ring 280 abutting against the end of the first tube body 230. A wedge-shaped inclined surface 290 is provided between the abutment portion 270 and the convex ring 280.

[0045] It is understandable that by tightening the locking nut 250 with the outer surface of the second tube body 240, the abutment portion 270 and the convex ring 280 are in contact and matched through the wedge-shaped inclined surface 290, and the sleeve 260 is elastically deformed to clamp the first tube body 230, thereby connecting and fixing the second tube body 240 and the first tube body 230.

[0046] The locking nut 250 is loosened from the outer surface of the second tube body 240, and the first tube body 230 can slide in the jacket 260, so that the length of the telescopic rod device 150 can be freely changed, thus making it simple and convenient to change the length of the telescopic rod device 150 itself.

[0047] In some embodiments of the present invention, referring to Figure 4 A through groove 300 is provided on the outer surface of the jacket 260 , and the through groove 300 extends along the end of the jacket 260 .

[0048] It should be noted that the jacket 260 may be made of plastic material, and the through groove 300 is used to facilitate elastic deformation of the jacket 260 , so that the jacket 260 firmly clamps the first tube 230 .

[0049] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
