Description

Technical Field

[0001] The invention belongs to the technical field of test instruments, and in particular relates to a test tube rack for an oil bath pot. Background Art

[0002] The oil bath is an instrument commonly used in chemical or biological laboratories for heating experiments. It is widely used for distillation, drying, concentration and impregnation of chemicals or biological products. It is an ideal and necessary tool for laboratory personnel in universities, colleges, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical industry, medical and other units. For example, when conducting food or drug testing, an oil bath is usually used. Generally, the bracket is placed in the oil bath first, and then the test tube is placed in the socket of the bracket so that the test tube is in direct contact with the heat transfer oil for oil bath operation. In the prior art, when the test tube is taken out of the oil bath, it is necessary to wipe it separately or let it stand to prevent the oil attached to the surface of the test tube from contaminating the test tube rack or even the work surface. The operation is cumbersome and the efficiency is low. Therefore, it is necessary to improve the existing test tube rack to facilitate and simplify the test operation. Summary of the invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and provides a test tube rack for an oil bath pot.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A test tube rack for an oil bath pot comprises a base and a top frame fixed to the base by a plurality of pillars; the top frame comprises an annular fixing plate, and an upturned outer edge is arranged on the outer side of the fixing plate; a concave platform is arranged in the middle of the upper surface of the base, and a liquid storage cavity is arranged inside the concave platform, and a discharge port connected with the liquid storage cavity is arranged at the edge of the base; a plurality of insertion holes are arranged on the fixing plate along the circumferential direction, and a liquid flow hole is arranged on the upper surface of the base corresponding to each insertion hole, the liquid flow hole is connected with the liquid storage cavity, and a supporting net is installed in the liquid flow hole; a liquid flow groove is arranged on the side wall of the insertion hole.

[0006] Furthermore, the jacks are evenly distributed along the center of the fixing plate.

[0007] Furthermore, the outer eaves and the fixing plate are an integrally formed structure.

[0008] Furthermore, an upper surface of the base is provided with an inclined surface inclined toward the concave platform.

[0009] Furthermore, a liquid passage hole communicating with the liquid storage cavity is provided at the bottom of the concave platform.

[0010] Furthermore, the fixing plate is provided with 6-10 sockets.

[0011] Furthermore, a cross bar is provided on the inner side of the fixing plate.

[0012] Furthermore, the support mesh is made of stainless steel mesh.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The invention has a reasonable structural design. When taking out the test tube from the oil bath pot, there is no need to wipe it. The test tube only needs to be placed in the jack of the fixed plate of the test tube rack, and the bottom of the test tube is against the supporting net in the liquid flow hole, and the test tube is left to stand. The oil will flow along the test tube to the base and enter the liquid storage cavity for collection, thereby avoiding pollution to the external environment, reducing the operation steps, and improving work efficiency.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] A test tube rack for an oil bath pot, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a top frame 3 fixed to the base by a plurality of pillars 2; the top frame includes a ring-shaped fixed plate 4, and an upturned outer edge 5 is provided on the outer side of the fixed plate; a concave platform 6 is provided in the middle of the upper surface of the base, and a liquid storage cavity is provided inside it, and a discharge port 7 connected to the liquid storage cavity is provided on the edge of the base; a plurality of plug holes 8 are provided on the fixed plate along the circumferential direction, and a liquid flow hole is provided on the upper surface of the base corresponding to each plug hole, and the liquid flow hole is connected to the liquid storage cavity, and a support net 9 is installed in the liquid flow hole; a liquid flow groove 10 is provided on the side wall of the plug hole. The test tube 14 is placed in the plug hole of the fixed plate of the test tube rack, and the bottom of the test tube is against the support net in the liquid flow hole.

[0023] Usually, the sockets are evenly distributed along the center of the fixed plate. The fixed plate is provided with 6-10 sockets. The support net is made of stainless steel net. A cross bar 13 is provided on the inner side of the fixed plate, which is very convenient for holding the test tube rack when lifting and placing it.

[0024] The outer eaves and the fixed plate are an integrally formed structure. The test tube taken out of the oil bath can be directly inserted into the fixed plate socket of the test tube rack. The oil on the outer wall of the test tube will flow downward along the test tube wall. The part of the test tube above the fixed plate will not overflow under the obstruction of the outer eaves, and will only flow downward along the socket on the fixed plate. The liquid flow trough provided ensures that the oil flowing downward passes through the socket smoothly. Of course, even if part of the oil flows downward without passing through the socket, it will flow downward to the base through the hollow part on the inner side of the fixed plate.

[0025] The oil flowing down the test tube will flow into the liquid storage cavity through the liquid flow hole, and the support net plays the role of supporting the test tube and allowing the oil to leak into the liquid storage cavity. Since the upper surface of the base is provided with an inclined surface 11 inclined toward the concave platform, the oil flowing to the surface of the base is allowed to flow into the concave platform. In an optional embodiment, the bottom of the concave platform is provided with a liquid hole 12 connected to the liquid storage cavity, and the oil flowing into the concave platform can flow into the liquid storage cavity through the liquid hole.

[0026] The invention has a reasonable structural design. When taking out the test tube from the oil bath pot, there is no need to wipe it. The test tube only needs to be placed in the jack of the fixed plate of the test tube rack, and the bottom of the test tube is against the supporting net in the liquid flow hole, and the test tube is left to stand. The oil will flow along the test tube to the base and enter the liquid storage cavity for collection, thereby avoiding pollution to the external environment, reducing the operation steps, and improving work efficiency.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
