[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] like Figure 1-6 As shown, the utility model provides a measurement tray, including a base body 1, a bracket 2, a flat support strip 3 and a test tube 4, the base body 1 is provided with a plurality of positioning pins 101, four positioning pins 101 form a group, corresponding to a bracket 2, for quickly positioning the bracket 2, optionally, the top of the base body 1 is also provided with a groove, the positioning pin 101 is provided on the inner bottom wall of the groove, and the outer side of the bracket 2 is fitted with the side wall of the groove, and the bracket 2 is doubly positioned by the groove and the positioning pin 101, thereby improving the positioning speed and the stability of the placement of the bracket 2; the bracket 2 is provided with a plurality of insertion holes 201 distributed in an array, and the bottom thereof is provided with positioning grooves 202 corresponding to the positioning pins 101 one by one, and the positioning grooves 202 are connected with the positioning pins 101, and the bracket 2 can be quickly positioned to prevent the bracket 2 from being stuck in the test tube 4; During the measurement, position shift occurs; the flat support strip 3 has a plurality of test tube holes 301 arranged in a linear manner, and the test tube holes 301 are aligned with the corresponding insertion holes 201. Correspondingly, it can be aligned with the array hole positions of the insertion holes 201, flat on its horizontal or vertical columns, and the test tube holes 301 on it are aligned with the insertion holes 201 below it, so that the test tubes 4 can be inserted. By placing a plurality of flat support strips 3 on the top of the bracket 2, the flat support strips 3 are used to distinguish test tubes containing different types of samples, which is convenient for distinction after measurement and for transferring the same type of test tubes together; the test tubes 4 are inserted into the aligned test tube holes 301 and the insertion holes 201 in sequence from top to bottom, and a step is provided on the outside of the test tube 4, which is placed on the top of the test tube hole 301, so that the flat support strip 3 can support the test tube 4.

[0029] It can be understood that at least one bracket 2 can be inserted on a base body 1. The length of the base body 1 can be increased according to needs, and the number of groups of positioning pins 101 can be increased synchronously according to the increased length; one flat support strip 3 corresponds to one type of sample test tube. When the test tube is inserted, different types are classified at the same time. When taking, the flat support strip 3 can be lifted at one time to transfer the sample test tubes of the same category together, thereby improving the convenience of operation; the measurement tray can be used in conjunction with automatic measurement instruments, and can also be used as a tray for sample test tubes in manual measurements, and can be used in conjunction with handheld measurement instruments for manual detection.

[0030] In this embodiment, in order to provide sufficient stability when placing the test tube 4, refer to Figure 2 The bracket 2 includes a plurality of layers 21, the number of which is three and distributed in sequence from top to bottom, and two fixing frames 22 arranged between the front and rear sides of the layers 21, which are used to fix the layers 21, wherein the jacks 201 are provided on the layers 21, that is, each layer 21 is provided with jacks 201 in an array. The upper, middle and lower parts of the test tube 4 can be supported by the plurality of layers 21 from top to bottom, thereby improving the stability of the bracket for the test tube 4.

[0031] In this embodiment, in order to provide quick positioning when the flat support strip 3 is installed flat, refer to Figure 2 and Figure 3 A plurality of through holes 203 are arranged in an array on the top of the bracket 2, and the through holes 203 are distributed in the intervals between the insertion holes 201. A positioning column 302 is arranged on the bottom of the flat support strip 3, and the positioning column 302 is plugged into the corresponding through hole 203. By plugging the positioning column 302 into the through hole 203, the flat support strip 3 is quickly positioned.

[0032] It is understandable that the number of flat support strips 3 is placed in accordance with the number of test tubes to be placed until the demand is met, and the through holes 203 distributed in the array can meet the positioning requirements of placing different numbers of flat support strips 3 within the array interval.

[0033] Furthermore, in order to be able to support the test tube 4 as a stand after it is taken out, the number of the positioning columns 302 is four, and the four positioning columns 302 all extend downward to penetrate the bottom of the bracket 2, so that after taking it out, the four positioning columns 302 can be used as support feet to support the test tube 4 as a stand, saving the use of an additional placement rack. In terms of operation, it also saves the step of placing the test tube on the placement rack separately after transferring it.

[0034] In order not to affect the installation of the adjacent flat support strips 3, the through hole 203 is circular in shape, and the positioning column 302 is semi-cylindrical in shape, that is, the positioning columns 302 on two adjacent flat support strips 3 can be inserted into the same through hole 203, and each occupies half of the space of the through hole 203.

[0035] In this embodiment, in order to facilitate the lifting of the flat support strip 3, refer to Figure 3 A lifting ear 303 is provided on the top of the flat support strip 3.

[0036] Specifically, the number of the lifting ears 303 is three, and the three lifting ears 303 are triangularly staggered on the top of the flat support strip 3, one lifting ear 303 is set at the top of the flat support strip 3 near the side, and the other two lifting ears 303 are set at the top of the flat support strip 3 near the other side, and the two lifting ears 303 are respectively located at the side front and side rear of one lifting ear 303, thereby forming a triangular staggered distribution. The effect of this distribution is that when adjacent flat support strips 3 are placed, the lifting ears 303 on them can be staggered to avoid the lifting ears 303 from sticking to each other and affecting the normal lifting operation.

[0037] In this embodiment, in order to meet the heating requirements of the test tube 4, the seat body 1 is a graphite plate heating seat, and the bottom end of the test tube 4 is flush with the top of the graphite plate heating seat, and the test tube 4 can be heated by the graphite heating seat.

[0038] It can be understood that the graphite heating seat is an existing mature equipment, which is heated by a graphite plate, and will not be described in detail here.

[0039] In this embodiment, refer to Figure 1 The flat support strips 3 are parallel to the longitudinal columns in which the insertion holes 201 are distributed in an array, and are inserted in the longitudinal columns.

[0040] For further information, see Figure 6 The flat support strips are parallel to the horizontal rows in which the insertion holes 201 are distributed in an array, and are inserted in the horizontal rows.

[0041] The length of the flat support strip 3 at least matches the linear length of three through holes 203 in a row. The flat support strip 3 can be manufactured in different lengths for combined use.

[0042] It can be understood that flat support strips 3 of different lengths can be made according to the number of test tubes 4 that need to be inserted, that is, the flat support strips 3 for three test tubes 4 correspond to the length of three insertion holes 201. On this column of the bracket 2, if the total vertical insertion holes 201 are eight, then a flat support strip 3 for five test tubes 4 can be inserted, or a flat support strip 3 for two test tubes 4 and a flat support strip 3 for three test tubes 4 can be inserted; in addition, the horizontal and vertical directions can be used in combination, and the flat support strips 3 can not only be inserted in the horizontal row, but also in the vertical row, and the operation can be performed according to the needs.

[0043] The specific working process of the utility model is as follows: the bracket 2 is inserted into the top of the base body 1, and the bracket 2 is positioned by plugging the positioning pin 101 into the positioning groove 202. In the measurement of the same type of samples to be measured, the test tube 4 can be directly inserted into the bracket 2 through the socket 201; in the measurement of different types of samples to be measured, the flat support strips 3 are first inserted into the top of the bracket 2 accordingly, one flat support strip 3 corresponds to one type of sample to be measured, or multiple flat support strips correspond to one type of sample to be measured, and the test tube 4 is inserted thereon and penetrated into the socket 201 of the bracket 2; after the measurement, the lifting ears 303 on the flat support strips 3 are used for hand-lifting, and the test tubes 4 of the same type are transferred together, and the positioning columns 302 are used as legs to form a bracket in conjunction with the flat support strips 3 to support and place the transferred test tubes 4.

[0044] The entire workflow is completed, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
