Description

Technical Field

[0001] The utility model relates to the technical field of atomic fluorescence photometers, and particularly relates to a matching storage device for an atomic fluorescence photometer. Background Art

[0002] A fluorescence spectrophotometer is an instrument used to scan the fluorescence spectra emitted by liquid-phase fluorescent markers. It can provide many physical parameters including excitation spectra, emission spectra, fluorescence intensity, quantum yield, fluorescence lifetime, fluorescence polarization, etc., which reflect the bonding and structure of molecules from various angles. By measuring these parameters, not only can general quantitative analysis be performed, but also the conformational changes of molecules in various environments can be inferred, thereby clarifying the relationship between molecular structure and function.

[0003] Currently, when an atomic fluorescence photometer needs to be transported, it is first placed in a storage box and then transported. The existing storage box for storing an atomic fluorescence photometer includes a box body and a box cover. A placement cavity is formed by the upper side of the box body recessing downward, that is, the opening of the box body faces upward. When placing the atomic fluorescence photometer into the storage box, the atomic fluorescence photometer is placed into the placement cavity through the opening at the upper end of the box body. Although the above storage box can accommodate the atomic fluorescence photometer, when the atomic fluorescence photometer needs to be taken out of the above storage box, the storage box needs to be placed on the tabletop of a placement table first, and then the atomic fluorescence photometer is removed from the opening at the upper end of the storage box by hand. When the bottom of the atomic fluorescence photometer moves to the upper side of the opening, the height difference between the atomic fluorescence photometer and the tabletop of the placement table is relatively large. If the atomic fluorescence photometer accidentally slips out of the hand at this time, the atomic fluorescence photometer is very likely to be damaged. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a matching storage device for an atomic fluorescence photometer to solve the technical problem that the atomic fluorescence photometer may be damaged when removed from the existing storage box.

[0005] The utility model is realized through the following technical solutions:

[0009] Further defined, a stop block is further included, and the stop block is arranged at one end of the sliding groove close to the opening.

[0010] Further defined, a support portion is further included, and the support portion is arranged on the carrier plate and is used to support the first end of the carrier plate when the carrier plate is moved out of the inner cavity of the box body.

[0011] Further defined, a groove is formed by downward depression on the lower side surface of the first end of the carrier plate; the support portion includes a support column and a torsion spring. One end of the support column is rotatably arranged in the groove, the other end of the support column protrudes downward from the groove, the end surface of the other end of the support column is flush with the lower side surface of the box body, and one end of the torsion spring is fixedly connected to the support column and the other end is fixedly connected to the side wall of the groove.

[0012] Further defined, the support portion further includes a shaft rod and a sleeve. The two ends of the shaft rod are respectively fixedly connected to the two side walls of the groove. The sleeve is sleeved on the shaft rod. The torsion spring is sleeved on the shaft rod and is located inside the sleeve.

One end of the support column is fixedly connected to the outer surface of the sleeve.

[0013] Further defined, the groove is arranged along the moving direction of the carrier plate, the shaft rod is arranged at one end of the groove close to the second end of the carrier plate, and the shaft rod is arranged perpendicular to the moving direction of the carrier plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] For the atom fluorescence photometer supporting storage device of the present utility model, since the opening is provided on a vertical side surface of the box body, after the carrier plate and the atom fluorescence photometer are horizontally removed from the inner cavity of the box body, the height difference between the atom fluorescence photometer and the tabletop is approximately the sum of the thicknesses of the bottom wall of the box body and the carrier plate. During the process of horizontally removing the atom fluorescence photometer from one side of the carrier plate by hand, the height difference between the atom fluorescence photometer and the tabletop is small.

[0031] Please refer to Figures 1-7, the present utility model provides a technical solution: a storage device for supporting an atomic fluorescence photometer, comprising a carrier plate 2, a box body 3, a cover plate 4 and a locking part 5. The carrier plate 2 is used for supporting the atomic fluorescence photometer 1, the box body 3 is used for accommodating the carrier plate 2 and the atomic fluorescence photometer 1, an opening is formed on the box body 3, and the opening is used for allowing the carrier plate 2 and the atomic fluorescence photometer 1 to horizontally move into or out of the inner cavity of the box body 3. The cover plate 4 is used for covering the opening, and the locking part 5 is used for locking the cover plate 4 on the box body 3.

[0032] When the storage device for supporting the atomic fluorescence photometer of the present utility model is in the initial state, the carrier plate 2 is located inside the box body 3, the cover plate 4 covers the opening, and the locking part locks the cover plate 4 on the box body 3. When the carrier plate 2 is located inside the inner cavity of the box body 3 and the cover plate 4 covers the opening, one end of the carrier plate 2 close to the opening is the first end of the carrier plate 2, and the end of the carrier plate 2 far from the opening is called the second end of the carrier plate 2. In the subsequent description, the first end and the second end of the carrier plate 2 both have this meaning.

[0033] Before transporting the atomic fluorescence photometer 1, place the box body 3 on the tabletop of the placement table, release the locking of the cover plate 4 by the locking part 5, then make the cover plate 4 separate from the box body 3, then horizontally move most of the carrier plate 2 out of the inner cavity of the box body 3 through the opening, and keep the second end of the carrier plate 2 supported on the bottom wall of the inner cavity of the box body 3. At this time, place the atomic fluorescence photometer 1 on the carrier plate 2 (please refer to Figure 8 shown), push the carrier plate 2, and the carrier plate 2 can drive the atomic fluorescence photometer 1 to horizontally move into the inner cavity of the box body 3 from the opening, then re-cover the cover plate 4 on the opening and lock the cover plate 4 on the box body 3 through the locking part 5.

[0034] When it is necessary to transport the atomic fluorescence photometer 1, the atomic fluorescence photometer 1 can be transported by carrying the box body 3.

[0035] After transporting the atomic fluorescence photometer 1 to the next use point and it is necessary to take out the atomic fluorescence photometer 1, place the box body 3 on the tabletop of the placement table, release the locking of the cover plate 4 by the locking part 5, then make the cover plate 4 separate from the box body 3, then horizontally move the carrier plate 2 and the atomic fluorescence photometer 1 out of the inner cavity of the box body 3 through the opening, make the first end of the carrier plate 2 supported on the tabletop of the placement table, and keep the second end of the carrier plate 2 supported on the bottom wall of the inner cavity of the box body 3 (please refer to Figure 8 shown). At this time, only need to horizontally move the atomic fluorescence photometer 1 from one side of the carrier plate 2 by hand and place the atomic fluorescence photometer 1 on the tabletop of the placement table. Please refer toFigure 2 and Figure 8 Since the opening is provided on a vertical side surface of the box body 3, after horizontally moving the carrier plate 2 and the atomic fluorescence spectrometer 1 out of the inner cavity of the box body 3, the height difference between the atomic fluorescence spectrometer 1 and the tabletop is approximately the sum of the thicknesses of the bottom wall of the box body 3 and the carrier plate 2. During the process of horizontally moving the atomic fluorescence spectrometer 1 from one side of the carrier plate 2 by hand, the height difference between the atomic fluorescence spectrometer 1 and the tabletop is small. Even if the atomic fluorescence spectrometer 1 accidentally slips out of the hand, the possibility of the atomic fluorescence spectrometer 1 being damaged is relatively low. Therefore, during the use of the atomic fluorescence spectrometer supporting storage device of the present utility model, the possibility of the atomic fluorescence spectrometer being damaged can be reduced.

[0036] In this embodiment, the cover plate 4 is fixedly connected to the first end of the carrier plate 2; the locking portion 5 includes a locking block 501 and a locking bolt 502. The locking block 501 is fixedly connected to the upper side surface of the cover plate 4. A first screw hole 6 is provided on the locking block 501, and a second screw hole 7 is provided on the box body 3. The first screw hole 6 corresponds to the second screw hole 7, and the locking bolt 502 is screwed into the first screw hole 6 and the second screw hole 7.

[0037] When the locking portion 5 locks the cover plate 4 to the box body 3, screw the screwing end of the locking bolt 502 into the first screw hole 6, and the screwing end of the locking bolt 502 passes through the first screw hole 6 and screws into the second screw hole 7, so that the cover plate 4 can be locked to the box body 3. With this structure, the locking portion 5 can lock the cover plate 4 to the box body 3.

[0038] When it is necessary to release the locking of the cover plate 4 by the locking portion 5, rotate the locking bolt 502 so that the screwing end of the locking bolt 502 is screwed out of the second screw hole 7, and the locking of the locking portion 5 to the cover plate 4 can be released. It is relatively convenient both when locking the cover plate 4 to the box body 3 and when releasing the locking of the locking portion 5.

[0039] In this embodiment, a sliding groove 8 is provided on the bottom wall of the inner cavity of the box body 3. The sliding groove 8 is arranged along the moving direction of the carrier plate 2. The notch size of the sliding groove 8 is smaller than the cavity size of the sliding groove 8. Specifically, the cross section of the sliding groove 8 is an inverted "T" shape. With this structure, the notch size of the sliding groove 8 can be smaller than the cavity size of the sliding groove 8; it further includes a sliding block 9. The sliding block 9 is fixedly connected to the lower side surface of the second end of the carrier plate 2, and the sliding block 9 is slidably matched in the sliding groove 8.

[0040] Since the sliding groove 8 is arranged along the moving direction of the bearing plate 2, and the slider 9 is slidably engaged in the sliding groove 8, the slider 9 cooperating with the sliding groove 8 can guide the movement of the bearing plate 2, making the horizontal movement of the bearing plate 2 more stable; since the notch size of the sliding groove 8 is smaller than the cavity size of the sliding groove 8, the possibility of the slider 9 disengaging from the sliding groove 8 upward can be reduced, that is, the possibility of the bearing plate 2 disengaging from the box body 3 upward can be reduced.

[0041] In this embodiment, the accessory storage device of the atomic fluorescence photometer of the present utility model further includes a stopper 10, and the stopper 10 is arranged at one end of the sliding groove 8 close to the opening.

[0042] The stopper 10 and the box body 3 are integrally formed. The stopper 10 is used to block one end of the sliding groove 8 close to the opening, so that the slider 9 cannot disengage from the sliding groove 8 after horizontal sliding, so that the bearing plate 2 can always be connected to the box body 3 during the process of moving out of the inner cavity of the box body 3, and further the second end of the bearing plate 2 can be kept supported on the bottom wall of the inner cavity of the box body 3.

[0043] In this embodiment, please refer to Figure 2 and Figure 8 , the accessory storage device of the atomic fluorescence photometer of the present utility model further includes a support portion 11, the support portion 11 is arranged on the bearing plate 2, and the support portion 11 is used to support the first end of the bearing plate 2 when the bearing plate 2 moves out of the inner cavity of the box body 3.

[0044] During the process of moving the bearing plate 2 and the atomic fluorescence photometer 1 out of the inner cavity of the box body 3, the lower end of the support portion 11 can be supported on the tabletop of the placement table, and the upper end can support the first end of the bearing plate 2, so that when the bearing plate 2 and the atomic fluorescence photometer 1 are moved out of the inner cavity of the box body 3, the bearing plate 2 can be kept in a relatively stable horizontal state.

[0045] In this embodiment, a groove 12 is formed by recessing the lower side surface of the first end of the bearing plate 2 upward; the support portion 11 includes a support column 1101 and a torsion spring 1102. One end of the support column 1101 is rotatably arranged in the groove 12, the other end of the support column 1101 protrudes downward from the groove 12, the end surface of the other end of the support column 1101 is flush with the lower side surface of the box body 3, and one end of the torsion spring 1102 is fixedly connected to the support column 1101 and the other end is fixedly connected to the side wall of the groove 12.

[0046] When moving the carrier plate 2 and the atomic fluorescence photometer 1 into the inner cavity of the box body 3 through the opening, rotate the support column 1101. The torsion spring 1102 connected to the support column 1101 deforms under the action of torsion. After the support column 1101 rotates, it is completely received in the groove 12, and then the carrier plate 2 can be completely moved into the inner cavity of the box body 3. When the carrier plate 2 is located in the inner cavity of the box body 3, the support column 1101 can be received in the groove 12 and will not protrude from the lower side surface of the carrier plate 2.

[0047] During the process of moving the carrier plate 2 and the atomic fluorescence photometer 1 out of the inner cavity of the box body 3 through the opening, the torsion spring 1102 can restore deformation and drive the support column 1101 to rotate. The other end of the support column 1101 can protrude from the groove 12 and support on the tabletop of the placement table, and the support column 1101 can support the first end of the carrier plate 2. With this structure, the support portion 11 can support the first end of the carrier plate 2 when the carrier plate 2 is moved out of the inner cavity of the box body 3.

[0048] In this embodiment, the support portion 11 further includes a shaft rod 1103 and a sleeve 1104. The two ends of the shaft rod 1103 are respectively fixedly connected to the two side walls of the groove 12. The sleeve 1104 is sleeved on the shaft rod 1103. The torsion spring 1102 is sleeved on the shaft rod 1103 and is located inside the sleeve 1104. One end of the torsion spring 1102 is fixedly connected to the sleeve 1104, that is, one end of the torsion spring is fixedly connected to the support column through the sleeve. It can be understood that in some embodiments, one end of the torsion spring 1102 can also be directly connected to the support column 1101. The other end of the torsion spring 1102 is fixedly connected to the side wall of the groove 12, and one end of the support column 1101 is fixedly connected to the outer surface of the sleeve 1104.

[0049] Since the support column 1101 is fixedly connected to the sleeve 1104, the sleeve 1104 is sleeved on the shaft rod 1103, and the two ends of the shaft rod 1103 are fixedly connected to the two side walls of the groove 12, one end of the support column 1101 can be rotatably arranged in the groove 12, and the rotation center line of the support column 1101 is the axis line of the shaft rod 1103.

[0050] When moving the carrier plate 2 and the atomic fluorescence photometer 1 out of the inner cavity of the box body 3, under the action of the torsion of the torsion spring 1102, the sleeve 1104 rotates, and the sleeve 1104 drives the support column 1101 to rotate, so that the other end of the support column 1101 protrudes from the groove 12 and supports on the tabletop, so that the support column 1101 can support the first end of the carrier plate 2.

[0051] In this embodiment, please refer to Figure 4 , Figure 5 and Figure 6 . The groove 12 is arranged along the moving direction of the bearing plate 2. The shaft rod 1103 is arranged at one end of the groove 12 close to the second end of the bearing plate 2, and the shaft rod 1103 is arranged perpendicular to the moving direction of the bearing plate 2.

[0052] Since the shaft rod 1103 is arranged at one end of the groove 12 close to the second end of the bearing plate 2, when the support column 1101 is retracted into the groove 12, the other end of the support column 1101 rotates towards the first end close to the bearing plate 2.

[0053] During the process of horizontally moving the bearing plate 2 into the inner cavity of the box body 3, the bearing plate 2 moves towards the inner cavity of the box body 3, and the support column 1101 also gradually approaches the box body 3 until one side surface of the support column 1101 abuts against the opening side of the box body 3. At this time, after continuing to push the bearing plate 2 into the inner cavity of the box body 3, the support column 1101 rotates around the shaft rod 1103 and is retracted into the groove 12 under the abutment of the opening side of the box body 3. With this structure, it is more convenient to retract the support column 1101 into the groove 12.

[0054] In this embodiment, the atom fluorescence photometer supporting storage device of the present utility model further includes a handle 13, and the handle 13 is fixedly connected to the upper side surface of the box body 3.

[0055] When it is necessary to carry the atom fluorescence photometer 1, hold the handle 13 to carry the atom fluorescence photometer supporting storage device of the present utility model, making it more convenient to carry the atom fluorescence photometer supporting storage device of the present utility model.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
