Description

Technical Field

[0001] This utility model belongs to the field of analytical testing technology, specifically relating to a placement box suitable for circular targets in laser ablation technology. Background Technology

[0002] Laser ablation-internal plasma micro-area (LA-ICP-MS) depth profiling technique enables high-resolution analysis of elements and isotopes with increasing depth by ablating the mineral surface layer by layer. A focused laser (193–266 nm) creates micron-sized ablation pits on the mineral surface, and the resulting aerosol particles are transported by a carrier gas (nitrogen / helium) to be detected by ICP-MS or a spectrometer. This method offers advantages such as minimal damage, in-situ measurement, and simultaneous multi-element determination, and is widely used in geodynamics research, resource exploration, and advanced materials development.

[0003] In the depth profiling method of in-situ laser micro-area ablation (LA-ICP-MS), different targets (carriers for fixing and supporting the sample) are used in the element determination process. Currently, the targets are mainly stored in target boxes, one target per box. However, since a large number of targets are required, the number of target boxes is also large. Cylindrical target boxes are easy to get messy when stacked, which can easily lead to the loss of target boxes. In addition, there are no labels on the target boxes. When changing targets, it is necessary to search for them and open the boxes to confirm whether they are the required targets. During the target change process, the targets are also easy to touch and cause wear. Utility Model Content

Detailed Implementation

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] This embodiment provides a storage box for circular targets used in laser ablation technology, addressing the technical problem of inconvenient storage of circular targets in existing technologies. The storage box for circular targets used in laser ablation technology includes a box body 2, a locking assembly 3, and a cover 9, wherein: refer to Figure 1 The box 2 has multiple orderly arranged placement cavities 21 that are adapted to the circular target 1. Specifically, the multiple placement cavities 21 can be arranged in a matrix, and the multiple circular targets 1 are placed in the multiple placement cavities 21 respectively. In this way, the placement cavities 21 adapted to the circular target 1 allow the circular target 1 to be placed more stably in the placement cavity 21, avoiding collision between the circular target 1 and the inner wall of the placement cavity 21 during the experiment.

[0020] refer to Figure 2 and Figure 4 There are multiple locking components 3, which are installed in multiple placement cavities 21 respectively. The multiple locking components 3 are arranged in a one-to-one correspondence with the multiple placement cavities 21, that is, each placement cavity 21 is provided with a set of locking components 3. The locking components 3 have a locked position and an unlocked position. The locking components 3 are configured such that: in response to being pressed, the locking components 3 are pressed from the unlocked position to the locked position. At this time, the top of the circular target 1 on the locking components 3 is in the same horizontal plane as the top of the box 2. This allows the circular target 1 to be placed more stably in the placement cavity 21. This also makes it convenient for the box 2 to be placed in the testing instrument as a target holder during experimental operations. In response to being pressed again, the locking components 3 are pushed from the locked position to the unlocked position. At this time, the circular target 1 on the locking components 3 protrudes from the placement cavity 21. This makes it easy to remove the circular target 1 and thus facilitates the replacement of the target in the box 2.

[0021] There are multiple covers 9, which are placed in multiple placement cavities 21. When the circular target 1 is placed in the placement cavity 21, the corresponding cover 9 is placed on the circular target. When an experiment is to be performed, the cover 9 can be removed.

[0022] The locking assembly 3 includes a mounting block 31, a locking block 32, an unlocking slider 33, a driving block 34, a locking pin 35, and a first elastic element 36, wherein: The mounting block 31 is installed inside the placement cavity 21. Optionally, the mounting block 31 is coaxially arranged with the placement cavity 21, so that the force on the mounting block 31 is more even.

[0023] The locking block 32 is fixedly installed on the top of the mounting block 31, and the locking block 32 and the mounting block 31 are coaxially arranged.

[0024] The unlocking slider 33 is slidably mounted on the mounting block 31. Specifically, the top of the unlocking slider 33 has a through hole that is adapted to the mounting block 31. The unlocking slider 33 is slidably mounted on the mounting block 31 through the through hole. The bottom wall of the unlocking slider 33 is inclined from the end away from the mounting block 31 to the end close to the mounting block 31 in a direction that is gradually away from the locking block 32. That is, the bottom wall of the unlocking slider 33 is an inclined surface. That is, there is an angle between the bottom wall of the unlocking slider 33 and the straight line containing the axis of the placement cavity 21. The angle ranges from 30° to 70°.

[0025] The drive block 34 is slidably installed in the placement cavity 21. The bottom wall of the drive block 34 is provided with a relief groove that is adapted to the mounting block 31. The inner diameter of the relief groove is equal to the maximum outer diameter of the unlocking slider 33, that is, the inner diameter of the relief groove is equal to the maximum outer diameter of the unlocking slider 33.

[0026] The locking pin 35 is slidably mounted in the drive block 34 along the radial direction of the clearance groove. In the initial state, one end of the locking pin 35 extends out of the drive block 34, and the side of the locking pin 35 near the mounting block 31 has an inclined surface from the end near the locking block 32 to the end away from the locking block 32, meaning that the side of the locking pin 35 near the mounting block 31 is an inclined surface. This means that the side of the locking pin 35 near the mounting block 31 forms an angle with the straight line containing the axis of the placement cavity 21, and this angle ranges from 30° to 70°. This inclined surface of the locking pin 35 facilitates the locking block 32 and the unlocking slider 33 in pushing the locking pin 35.

[0027] The first elastic element 36 is sleeved outside the unlocking slider 33 and located between the placement cavity 21 and the drive block 34. In this way, the setting of the first elastic element 36 makes it easy to push the drive block 34 to reset.

[0028] With the above structure, when the locking assembly 3 needs to be moved to the locking position, pressing the driving block 34 causes it to slide downwards within the placement cavity 21, compressing the first elastic element 36. Simultaneously, this causes the locking pin 35, installed within the driving block 34, to move downwards until the bottom edge of the inclined surface of the locking pin 35 contacts the locking block 32. Further pressing the driving block 34 downwards causes the inclined surface of the locking pin 35 to be compressed by the mounting block 31, and the inclined surface of the locking pin 35 to continue sliding downwards against the outer wall of the locking block 32. As the locking pin 35 gradually moves away from the mounting block 31, until the inclined surface of the locking pin 35 is completely separated from the outer wall of the locking block 32, the force squeezing the locking pin 35 disappears, the locking pin 35 returns, and at the same time the locking pin 35 engages in the gap between the locking block 32 and the unlocking slider 33, the driving block 34 is released, the first elastic element 36 returns, and the driving block 34 is squeezed upward, so that the top of the locking pin 35 extending from the driving block 34 abuts against the bottom of the locking block 32, that is, the latch assembly 3 is pressed to the locked position;When the locking assembly 3 needs to be moved to the unlocked position again, press the drive block 34 again. The drive block 34 continues to move downward, causing the locking pin 35 mounted on the drive block 34 to move downward synchronously until the locking pin 35 extends out of one end of the drive block 34, that is, the inclined surface of the locking pin 35 abuts against the side of the top of the unlocking slider 33. Continue pressing the drive block 34, and the inclined surface of the locking pin 35 pushes the unlocking slider 33 downward synchronously until the unlocking slider 33 slides to the bottom of the mounting block 31. Continue pressing the drive block 34 again, and the unlocking action is initiated by the inclined surface of the locking pin 35. The side edge of the top of slider 33 begins to press against locking pin 35, and locking pin 35 gradually moves away from mounting block 31. Simultaneously, the inclined surface of locking pin 35 continues to slide downwards against the side edge of the top of unlocking slider 33 until the inclined surface of locking pin 35 completely separates from the side edge of the top of unlocking slider 33, and the top edge of the inclined surface of locking pin 35 abuts against the outer wall of unlocking slider 33. Continue pressing drive block 34 until the top edge of the inclined surface of locking pin 35 abuts against the inclined surface of unlocking slider 33, the force pressing on locking pin 35 disappears, locking pin 35 returns to its original position, and simultaneously pushes unlocking slider 33 upwards. Sliding, at this point, the drive block 34 is released again, the first elastic element 36 returns to its original position, driving the drive block 34 to slide upward, simultaneously causing the locking pin 35 to push the unlocking slider 33 to continue sliding upward until the top of the unlocking slider 33 is in contact with the bottom of the locking block 32. Driven by the first elastic element 36, the drive block 34 continues to move upward. As the locking pin 35 is squeezed, the top edge of the inclined surface of the locking pin 35 slides upward against the inclined surface of the unlocking slider 33 until the top edge of the inclined surface of the locking pin 35 is completely separated from the inclined surface of the unlocking slider 33. The outer walls of block 33 abut against each other, and the top edge of the inclined surface of locking pin 35 continues to slide upward against the outer wall of unlocking slider 33. Because the maximum outer diameter of unlocking slider 33 is equal to the outer diameter of locking block 32, the outer wall of unlocking slider 33 is in contact with the outer wall of locking block 32. After the top edge of the inclined surface of locking pin 35 separates from the outer wall of unlocking slider 33, it continues to slide to the outer wall of locking block 32. At this time, the first elastic element 36 continues to return until the top edge of the inclined surface of locking pin 35 is completely separated from the outer wall of locking block 32, that is, the latch assembly 3 is pushed to the unlock position.

[0029] Optionally, the top wall of the unlocking slider 33 is inclined from the end away from the mounting block 31 to the end closer to the mounting block 31 towards the locking block 32. That is, the top wall of the unlocking slider 33 is also an inclined surface. The bottom wall of the locking block 32 is provided with an inlay groove 321 that matches the top of the unlocking slider 33. In this way, the inclined top edge makes it easier for the locking pin 35 to connect with the unlocking slider 33. The inlay groove 321 prevents the locking pin 35 from sliding smoothly from the side wall of the unlocking slider 33 to the outer side wall of the locking block 32 during the unlocking process.

[0030] refer to Figure 3It also includes a base 4, a connecting rod 5, and a second elastic element 6, wherein: The inner wall of the relief groove is provided with an installation groove, and the installation groove is set along the radial direction of the relief groove. The inner diameter of the installation groove is equal to the outer diameter of the locking pin 35. The base 4 is installed at the bottom of the installation groove. The connection rod 5 is more easily slidably installed by the base 4.

[0031] The base 4 has a groove that matches the connecting rod 5. One end of the connecting rod 5 is slidably installed in the groove, and one end of the locking pin 35 extends into the groove and is connected to the other end of the connecting rod 5. In this way, the locking pin 35 can move in the radial direction of the placement cavity 21 through the cooperation of the connecting rod 5 and the groove.

[0032] The second elastic element 6 is sleeved outside the connecting rod 5 and located between the base 4 and the locking pin 35. In this way, the setting of the second elastic element 6 makes it easier to drive the locking pin 35 to reset.

[0033] With the above structure, when the locking pin 35 is squeezed by an external force, the locking pin 35 moves toward the base 4 and squeezes the second elastic member 6 installed between the locking pin 35 and the base 4. When the external force squeezing the locking pin 35 disappears, the force squeezing the second elastic member 6 also disappears, the second elastic member 6 returns, and pushes the locking pin 35 and the connecting rod 5 connected to the locking pin 35 to move synchronously away from the base 4.

[0034] Optionally, there are multiple locking pins 35, all of which are slidably installed in the drive block 34 and evenly distributed along the circumferential direction of the clearance groove. In this way, by setting multiple locking pins 35, the failure of the locking pin 35 will prevent the locking assembly 3 from also failing, thus reducing the probability of the locking assembly 3 failing. The evenly distributed locking pins 35 also make the force on each locking pin 35 more uniform, preventing the locking assembly 3 from failing due to uneven force on the locking pin 35.

[0035] Optionally, both the first elastic element 36 and the second elastic element 6 are springs, which can store energy and release the energy at the appropriate time to drive the drive block 34 and the locking pin 35 to reset. The spring has a simple structure and low cost.

[0036] The outer diameter of the locking block 32 gradually increases from the bottom end to the top end of the locking block 32. The maximum outer diameter of the unlocking slider 33 is equal to the outer diameter of the well section of the locking block 32. In this way, the locking block 32, which is shaped like a frustum, makes it easier for the locking pin 35 to abut against the outer wall of the locking block 32.

[0037] Mounting block 31 includes frustum-shaped pad block 311 and connecting block 312, wherein: The large-diameter end of the frustum pad 311 is installed on the bottom wall of the placement cavity 21. In this way, the frustum pad 311 prevents the gap between the unlocking slider 33 and the bottom wall of the placement cavity 21 from being too small, which would prevent the locking pin 35 from engaging in the gap between the bottom wall of the unlocking slider 33 and the bottom wall of the placement cavity 21, thus causing the unlocking to fail.

[0038] One end of the connecting block 312 is installed on the small diameter end of the frustum pad 311, and the outer diameter of the connecting block 312 is smaller than the outer diameter of the small diameter end of the frustum pad 311, so as to prevent the unlocking slider 33 from coming off the connecting block 312.

[0039] It also includes a label 7, which is set on the top of the box 2. There are multiple labels 7, and each label 7 is set in a one-to-one correspondence with a multiple placement cavity 21. In this way, the setting of the label 7 makes it easier to quickly identify the circular target 1 inside the box 2.

[0040] It also includes a sponge layer 8, which is disposed on the outer side wall of the drive block 34 and the inner top wall of the cover 9. In this way, by disposing of the sponge layer 8 on the drive block, the friction between the drive block 34 and the inner side wall of the placement cavity 21 is increased, so as to prevent the circular target 1 from being ejected from the placement cavity 21 too quickly when the drive block 34 rises; while the sponge layer 8 disposed on the inner top wall of the cover 9 reduces the probability of the circular target 1 being damaged.

[0041] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
