Description

Technical Field

[0001] This application belongs to the field of spectroscopic analysis equipment technology, and more specifically, relates to a sample tray structure. Background Technology

[0002] Atomic fluorescence spectrometers mainly use spectral analysis technology to detect the heavy metal content in samples. The sample tray used with its automatic sample introduction component is usually composed of multiple support plates and a base plate. Each support plate is arranged at intervals along the vertical direction and has multiple fixing holes to fix multiple sample tubes containing the test samples for batch sample introduction.

[0003] Due to the corrosion resistance requirements during testing, existing support plates are mostly made of rigid materials such as quartz glass or polytetrafluoroethylene (PTFE). However, the production of these plates relies on laser cutting or hot injection molding, which is costly and not suitable for small-scale customization by small laboratories or research institutions. Although support plates made of soft PVC sheets can meet the same corrosion resistance requirements, their soft nature makes them easy to cut and drill manually, resulting in relatively low production costs and no reliance on industrial equipment, the structural strength of soft PVC sheets is insufficient when they meet the condition of being easy to cut and drill manually. This leads to insufficient support strength and poor stability of the final assembled sample tray, making it easy for the sample tube to tip over accidentally during sample injection. Utility Model Content

[0004] The purpose of this application is to provide a sample tray structure that addresses the problem that while flexible PVC sheets are easy to cut and drill, their structural strength is insufficient, resulting in inadequate support strength and poor stability in the final assembled sample tray. Consequently, the sample tubes are prone to tipping over during sample injection.

[0005] To achieve the above objectives, the technical solution adopted in this application is to provide a sample tray structure, including a rotating shaft fixing support, a first soft support plate, a second soft support plate, a reinforcing soft ring plate, and a reinforcing hard ring pad.

[0008] In one embodiment, the axial height of the first support column is less than the axial height of the second support column, which results in the vertical distance between the support base body and the first flexible support plate being less than the vertical distance between the first flexible support plate and the second flexible support plate.

[0009] In one embodiment, the first soft support plate and the reinforcing soft ring plate are stitched together by 2N first suture units equidistantly arranged along the circumference of the first soft support plate, and the 2N first suture units are centrally symmetrically arranged along any radial direction of the first soft support plate; the second soft support plate and the reinforcing soft ring plate are stitched together by 2N second suture units equidistantly arranged along the circumference of the second soft support plate, and the 2N second suture units are centrally symmetrically arranged along any radial direction of the second soft support plate; wherein, N is a natural number greater than 0.

The second suture unit includes a second suture thread, a fourth preset suture hole, a fifth preset suture hole, and a sixth preset suture hole. The fourth, fifth, and sixth preset suture holes are arranged sequentially and at intervals along the circumference of the second soft support plate on the same horizontal plane. The fourth and sixth preset suture holes are both opened on the reinforcing flexible ring plate, and the fifth preset suture hole is opened on the second soft support plate.

After passing through the vertical gap between the reinforcing hard ring pad and the second soft support plate, a fifth pre-set slot is provided on the underside of the second soft support plate, and a sixth pre-set slot is provided on the inner side of the reinforcing soft ring plate. The end of the third tie wire is fixed on the outer side of the reinforcing soft ring plate to form a third abutting point abutting against the outer peripheral edge of the fourth pre-set slot, and the end of the fourth tie wire is fixed on the outer side of the reinforcing soft ring plate to form a fourth abutting point abutting against the outer peripheral edge of the sixth pre-set slot.

[0012] In one embodiment, the thickness of the first soft support plate, the second soft support plate, and the reinforcing soft ring plate is 0.3-1.0 mm, the vertical distance between the first soft support plate and the base connecting ring plate is 16-20 mm, the vertical distance between the second soft support plate and the first soft support plate is 46-50 mm, and the vertical height of the reinforcing hard ring pad is 43-46 mm.

[0013] In one embodiment, the bottom of the support base body is provided with an installation groove, and the second flexible support plate is provided with multiple through hole markings that correspond one-to-one with multiple second fixing through holes.

[0014] The beneficial effects of the sample tray structure provided in this application are that, compared with the prior art, the sample tray structure still uses a rotating shaft fixing support, a first soft support plate, and a second soft support plate to support and fix the sample tube. Due to the structural characteristics of the first soft support plate, the second soft support plate, and the reinforcing soft ring plate, it is easy to manually cut and open holes during the preparation process, thus making the preparation cost relatively low. In addition, by further utilizing the soft properties of the first soft support plate, the second soft support plate, and the reinforcing soft ring plate, the first soft support plate and the second soft support plate are stitched together with the reinforcing soft ring plate. Furthermore, an additional reinforcing hard ring pad is set between the first soft support plate and the second soft support plate to effectively improve the structural strength of the first soft support plate and the second soft support plate. Thus, while maintaining the relatively low preparation cost of the sample tray structure, the supporting strength of the sample tray structure is effectively strengthened, thereby improving the stability of the sample tray structure and avoiding the accidental tipping of the sample tube during sample injection.

[0026] Please refer to the following: Figure 1 and Figure 2The sample tray structure 10 provided in one embodiment of this application will now be described. The sample tray structure 10 includes a rotating shaft fixing support 100, a first soft support plate 200, a second soft support plate 300, a reinforcing soft ring plate 400, and a reinforcing hard ring pad 500. The first soft support plate 200 and the second soft support plate 300 are vertically spaced on the rotating shaft fixing support 100. The first soft support plate 200 and the second soft support plate 300 are respectively provided with a plurality of first fixing through holes 210 and a plurality of second fixing through holes 310. Each first fixing through hole 210 and each second fixing through hole 310 are vertically aligned and communicate with each other. The rotating shaft fixing support 100, the first soft support plate 200, and the second soft support plate 300 cooperate to allow passage through the plurality of vertically aligned first fixing through holes. Hole 210 and multiple second fixed through holes 310 support and fix the sample tube (not shown in the figure). That is, the sample tube passes through the corresponding first fixed through hole 210 and second fixed through hole 310 and is supported on the rotating shaft fixed support 100. The reinforcing soft ring plate 400 is arranged around the outer periphery of the first soft support plate 200 and the second soft support plate 300, and the outer periphery edges of the first soft support plate 200 and the second soft support plate 300 are respectively sewn together. The reinforcing hard ring pad 500 is arranged around the inner side of the reinforcing soft ring plate 400 and is supported between the first soft support plate 200 and the second soft support plate 300. The reinforcing soft ring plate 400 and the reinforcing hard ring pad 500 are used to improve the structural strength of the first soft support plate 200 and the second soft support plate 300, thereby improving the support strength of the sample plate structure 10.

[0027] It should be noted that, in this embodiment, the second flexible support plate 300 is provided with multiple through hole markings (not shown in the figure) corresponding one-to-one with multiple second fixing through holes 310. The first flexible support plate 200, the second flexible support plate 300 and the reinforcing flexible ring plate 400 are all transparent polyvinyl chloride sheets with a plasticizer content of 30-50%, so as to have relatively suitable flexible properties. In a specific embodiment, the plasticizer content in the first flexible support plate 200, the second flexible support plate 300 and the reinforcing flexible ring plate 400 is 35%.

[0028] The beneficial effect of the sample tray structure 10 provided in this application is that, compared with the prior art, the sample tray structure 10 still uses the rotating shaft fixing support 100, the first soft support plate 200, and the second soft support plate 300 to achieve the supporting and fixing function of the sample tube. Due to the structural characteristics of the first soft support plate 200, the second soft support plate 300, and the reinforcing soft ring plate 400, it is easy to manually cut and open holes during the preparation process, thus making the preparation cost relatively low. In addition, by further utilizing the first soft support plate 200, the second soft support plate 300, and the reinforcing soft ring plate 400... The soft properties of the sample tray structure 10 enable the stitching connection between the first soft support plate 200 and the second soft support plate 300 and the reinforcing soft ring plate 400. Furthermore, a reinforcing hard ring pad 500 is added between the first soft support plate 200 and the second soft support plate 300 to effectively improve the structural strength of the first soft support plate 200 and the second soft support plate 300. In this way, while maintaining the relatively low preparation cost of the sample tray structure 10, the support strength of the sample tray structure 10 is effectively strengthened, the stability of the sample tray structure 10 is effectively improved, and the sample tube is prevented from accidentally tipping over during sample injection.

[0029] Furthermore, in this embodiment, the aforementioned rotating shaft fixing support 100 includes a supporting base body 110, a connecting rotating shaft body 120, and a base connecting ring plate 130. The supporting base body 110, the first flexible support plate 200, and the second flexible support plate 300 are all disc structures and are arranged coaxially at intervals along the vertical direction. The connecting rotating shaft body 120 is coaxially disposed on the supporting base body 110, and the first flexible support plate 200 and the second flexible support plate 300 are correspondingly coaxially inserted in sequence. The base connecting ring plate 130 is ring-shaped. The base is located on the outer periphery of the base body, and the base connecting ring plate 130 is bonded to the base body. The reinforcing soft ring plate 400 is bonded to the base connecting ring plate 130. The corresponding sample tubes are inserted through the corresponding connected first fixed through hole 210 and second fixed through hole 310 and supported on the base connecting ring plate 130. In some other embodiments, the corresponding sample tubes are inserted through the corresponding connected first fixed through hole 210 and second fixed through hole 310 and supported on the base connecting ring plate 130 or on the base body 110.

[0030] Furthermore, in this embodiment, the aforementioned support base body 110 is provided with an installation slot (not shown in the figure) for forming an insertion fit with a photometer (not shown in the figure), the base connecting ring plate 130 is a paper board covered with waterproof tape, the base connecting ring plate 130 is bonded to the support base body 110 by adhesive tape, and the reinforcing soft ring plate 400 is bonded to the base connecting ring plate 130 by adhesive tape.

[0031] Furthermore, in this embodiment, the aforementioned rotating shaft fixing support 100 also includes a plurality of reinforcing support columns 140 equidistantly arranged on the support base body 110 along the circumference of the support base body 110. The reinforcing support columns 140 are used to support the first soft support plate 200 and the second soft support plate 300 together, thereby further improving the structural strength of the first soft support plate 200 and the second soft support plate 300.

[0032] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the aforementioned reinforcing support column 140 includes a first support column 141, a second support column 142, a first connecting screw 143, and a second connecting screw 144. The first support column 141 and the second support column 142 are coaxially spaced along the vertical direction. The first support column 141 is supported between the support base body 110 and the first flexible support plate 200, and the second support column 142 is supported between the first flexible support plate 200 and the second flexible support plate 300. The first connecting screw 143 is located on the back of the support base body 110. A support base body 110, a first support column 141, a first flexible support plate 200, and a second support column 142 are sequentially inserted through one end of the first flexible support plate 200.

An abutment washer 145 is provided between the head of the second connecting screw 144 and the second flexible support plate 300.

[0033] Furthermore, in this embodiment, the axial height of the first support column 141 in the vertical direction is less than the axial height of the second support column 142 in the vertical direction, which makes the vertical distance between the support base body 110 and the first soft support plate 200 less than the vertical distance between the first soft support plate 200 and the second soft support plate 300, so as to improve the overall stability of the sample plate structure 10.

[0034] Furthermore, in this embodiment, the first soft support plate 200 and the reinforcing soft ring plate 400 are stitched together by 2N first suture units 600 arranged equidistantly along the circumference of the first soft support plate 200. The 2N first suture units 600 are centrally symmetrically arranged radially along the first soft support plate 200. Similarly, the second soft support plate 300 and the reinforcing soft ring plate 400 are stitched together by 2N second suture units 700 arranged equidistantly along the circumference of the second soft support plate 300. The 2N second suture units 700 are centrally symmetrically arranged radially along the second soft support plate 300. Here, N is a natural number greater than 0. It should be noted that during the stitching process of the multiple first suture units 600, any two first suture units 600 stitched sequentially are mirror-symmetrical. Similarly, during the stitching process of the multiple second suture units 700, any two second suture units 700 stitched sequentially are mirror-symmetrical.

The outer side of the strong soft ring plate 400 is fixed to form a second abutment point abutting against the outer peripheral edge of the third preset suture hole 630, so as to form a relatively stable multi-strand cross tension between the first soft support plate 200 and the reinforcing soft ring plate 400. It should be noted that, due to the soft characteristics of the first soft support plate 200 and the reinforcing soft ring plate 400, the first soft support plate 200 and / or the reinforcing soft ring plate 400 can be appropriately bent and deformed at appropriate times during the suturing process, so as to perform the corresponding suturing operation.

[0036] Please see Figure 2 and Figure 5In this embodiment, the vertical height of the reinforcing rigid ring pad 500 is less than the vertical distance between the first soft support plate 200 and the second soft support plate 300, thereby reserving a suturing gap for subsequent suturing operations.
