[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the graphite tube installation device provided by the embodiment of the utility model includes a clamping assembly 100 and a vertical detection assembly 200. The clamping assembly 100 includes a clamping jaw 110 and a supporting component 120. The lower end of the supporting component 120 is connected to the clamping jaw 110. The upper end of the supporting component 120 is provided with the vertical detection assembly 200. The vertical detection assembly 200 is used to detect the verticality of the injection hole 510 on the graphite tube 500 clamped by the clamping jaw 110.

[0034] In the graphite tube installation device of the embodiment of the utility model, the support component 120 of the clamping assembly 100 is connected to the clamping jaw 110. The staff can operate the support component 120 to drive the clamping jaw 110 to move, and then clamp the graphite tube 500 through the clamping jaw 110. The vertical detection component 200 is set on the support component 120.

[0035] The graphite tube installation device of this embodiment is used to install the graphite tube 500 on an atomic absorption spectrometer for element detection experiments. During the installation process, the clamping component 100 cooperates with the vertical detection component 200 to continuously adjust the position of the injection hole 510 of the graphite tube 500 and fine-tune the position of the instrument injection needle until the detection requirements are met, which saves time and effort and effectively improves the installation efficiency of the graphite tube 500 and the element detection efficiency. The device has a simple structure, low cost, and is easy to operate.

[0036] According to an embodiment provided by the utility model, the supporting component 120 includes a first supporting plate 121, a second supporting plate 122 and a connecting plate 123, the clamping jaw 110 includes a first clamping plate 111 and a second clamping plate 112, the first clamping plate 111 and the second clamping plate 112 are arranged opposite to each other, the upper end of the first supporting plate 121 is connected to the upper end of the second supporting plate 122 through the connecting plate 123, the lower end of the first supporting plate 121 is connected to the first clamping plate 111, and the lower end of the second supporting plate 122 is connected to the second clamping plate 112.

[0037] In this embodiment, the support component 120 and the clamping jaw 110 form a clamping assembly 100 in the shape of tweezers. The support component 120 is composed of a first support plate 121, a second support plate 122 and a connecting plate 123. The first support plate 121 and the second support plate 122 are both vertically arranged, and the connecting plate 123 is horizontally arranged and connected to the upper ends of the first support plate 121 and the second support plate 122. The clamping jaw 110 is composed of a first clamping plate 111 and a second clamping plate 112. The first support plate 121 is connected to the first clamping plate 111, and the second support plate 122 is connected to the second clamping plate 112. Therefore, the staff controls the movement of the first support plate 121 and the second support plate 122, thereby controlling the movement of the first clamping plate 111 and the second clamping plate 112. The first clamping plate 111 and the second clamping plate 112 cooperate to clamp the graphite tube 500. The support component 120 and the clamping jaw 110 have a simple structure, are easy to manufacture, save costs, and are convenient to operate.

[0038] In other embodiments, the support component 120 and the clamp 110 may also adopt other structures, and the clamp 110 can only achieve the effect of clamping and fixing the graphite tube 500, and the support component 120 can be held by the staff and drive the clamp 110 to move and adjust the position.

[0039] According to an embodiment provided by the utility model, the first support plate 121 and the second support plate 122 are arranged opposite to each other, the first support plate 121, the connecting plate 123 and the second support plate 122 enclose an accommodation space 125, and the vertical detection assembly 200 is arranged in the accommodation space 125. In this embodiment, the first support plate 121 and the second support plate 122 are plates with a certain width, the first support plate 121 and the second support plate 122 are arranged relatively parallel, and the first support plate 121 and the second support plate 122 are spaced a certain distance apart, the connecting plate 123 cooperates with the first support plate 121 and the second support plate 122 to limit the accommodation space 125, that is, the accommodation space 125 is located above the clamping jaw 110, the vertical detection assembly 200 is arranged in the accommodation space 125, the overall structure is more compact, and the vertical detection assembly 200 does not occupy the space outside the support component 120.

[0040] In this embodiment, the vertical detection assembly 200 is located directly above the clamping jaw 110 , that is, the vertical detection assembly 200 detects the verticality of the injection hole 510 above the graphite tube 500 , which better meets the installation requirements of the graphite tube 500 .

[0041] According to an embodiment provided by the utility model, the vertical detection assembly 200 includes a control component 210, a sphere 220 and a suspension rope 230. The control component 210 is arranged in the accommodating space 125. The two ends of the control component 210 are respectively connected to the first support plate 121 and the second support plate 122. The sphere 220 is suspended under the control component 210 by the suspension rope 230, and there is a gap between the sphere 220 and the first support plate 121 and the second support plate 122. In this embodiment, the vertical detection assembly 200 includes a control component 210, a suspension rope 230 and a sphere 220 from top to bottom. The control component 210 is horizontally placed between the first support plate 121 and the second support plate 122, and is located below the connecting plate 123. The suspension rope 230 is connected to the bottom of the control component 210, and the sphere 220 is connected through the suspension rope 230, so that the sphere 220 is suspended below the control component 210. The diameter of the sphere 220 is smaller than the distance between the first support plate 121 and the second support plate 122, so there is a gap between the sphere 220 and the first support plate 121, and there is also a gap between the sphere 220 and the second support plate 122.

[0042] In this embodiment, since the sphere 220 is in a suspended state, when the clamping assembly 100 is in a vertical state, the sphere 220 is suspended vertically to maintain the gap between the sphere 220 and the first support plate 121 and the second support plate 122. The control component 210 has no detection result, indicating that the sampling hole 510 of the graphite tube 500 clamped by the clamping assembly 100 is also maintained in a vertical state. However, when the clamping assembly 100 deviates at a certain angle in the intersecting vertical direction, the sampling hole 510 of the clamped graphite tube 500 will also be offset at an angle, thereby causing its vertical position to change greatly. The sphere 220 will continue to remain vertically suspended due to the influence of gravity in the suspended state. Compared with the sphere 220 when the clamping assembly 100 is in a vertical state, it will swing. Therefore, the deflection of the first support plate 121 or the second support plate 122 will reduce the gap between it and the sphere 220 until it contacts the sphere 220. The control component 210 obtains a detection result, indicating that the sampling hole 510 of the graphite tube 500 clamped by the clamping assembly 100 has been deflected.

[0043] The vertical detection assembly 200 suspended by the sphere 220 cooperates with the first support plate 121 and the second support plate 122 corresponding to the setting position of the sphere 220 on the support component 120. The overall structure is simple and the detection result is accurate and reasonable. The staff can not only learn the vertical state of the sampling hole 510 of the graphite tube 500 from the feedback of the control component 210, but also judge the vertical state of the sampling hole 510 of the graphite tube 500 by observing the shaking of the sphere 220, which is more intuitive and convenient.

[0044] In this embodiment, the gap between the sphere 220 and the first support plate 121 is about 1-2 mm, and the gap between the sphere 220 and the second support plate 122 is about 1-2 mm, so as to ensure that the clamping assembly 100 can make the sphere 220 contact with the first support plate 121 or the second support plate 122 as long as it is deflected at a small angle, and the control component 210 can detect the change in the verticality of the injection hole 510 of the graphite tube 500. The control component 210 includes a housing and a control element located in the housing, and a corresponding induction circuit connected to the control element is set on the first support plate 121 and the second support plate 122. When the sphere 220 contacts the first support plate 121 or the second support plate 122, the circuit connection signal is transmitted to the control element.

[0045] The outer shell includes a cross bar 211 and four support rods 212. The four support rods 212 are grouped in pairs. The two support rods 212 in each group of support rods 212 are connected to the support component 120 at one end, and the other ends gradually gather toward the middle from top to bottom until they are connected to each other. The connection positions of the two groups of support rods 212 are connected through the cross bar 211. The cross bar 211 is horizontally arranged and perpendicular to the direction from the first support plate 121 to the second support plate 122. Two hanging rings 213 are arranged on the cross bar 211, and each hanging ring 213 is arranged on a hanging rope 230, that is, two hanging ropes 230 are symmetrically arranged on the sphere 220 to be connected to the control component 210.

[0046] In other embodiments, the vertical detection assembly 200 may also be other structures, such as a verticality detection sensor, etc., which emits infrared rays or lasers, etc., aimed at the injection hole 510 of the graphite tube 500, and receives the reflected signal to detect the verticality of the injection hole 510.

[0047] According to an embodiment provided by the utility model, the graphite tube installation device further includes an alarm indicator light 300, and the alarm indicator light 300 is connected to the control component 210. In this embodiment, the alarm indicator light 300 is arranged on the upper surface of the connecting plate 123, and when the control component 210 obtains a detection signal, proving that the verticality of the injection hole 510 of the graphite tube 500 changes, the control component 210 can control the alarm indicator light 300 to light up, and the staff can know whether the position of the injection hole 510 of the graphite tube 500 is appropriate through the light signal of the alarm indicator light 300.

[0048] In this embodiment, the control elements in the control component 210 include electronic elements for the vertical detection assembly 200 and also include electronic elements for the alarm indicator light 300 .

[0049] According to an embodiment provided by the utility model, the supporting component 120 also includes a partition 124, the two ends of which are respectively connected to the first support plate 121 and the second support plate 122, and the partition 124, the first support plate 121, the connecting plate 123 and the second support plate 122 enclose a accommodating space 125, and there is a gap between the partition 124 and the sphere 220.

[0050] In this embodiment, the space between the first support plate 121 and the second support plate 122 is divided into two parts by the partition 124, that is, the partition 124 separates the accommodating space 125 where the vertical detection component 200 is located from the clamping space 113 involved in the clamping claw 110, so that the position of the accommodating space 125 is relatively independent, ensuring the spatial range of the accommodating space 125, and cooperating with the connecting plate 123 to support and increase the strength of the first support plate 121 and the second support plate 122 corresponding to the accommodating space 125 to prevent deformation, effectively preventing the first support plate 121 and the second support plate 122 corresponding to the vertical detection component 200 from partially deforming when the staff applies force to the first support plate 121 and the second support plate 122 to make the first clamping plate 111 and the second clamping plate 112 close to the clamping graphite tube 500, even when the sphere 220 is vertically suspended, the first support plate 121 or the second support plate 122 contacts the sphere 220 due to deformation, resulting in inaccurate detection results.

[0051] In order to ensure that the sphere 220 is always in a suspended state, a certain gap needs to be provided between the sphere 220 and the partition 124 therebelow, and the partition 124 does not contact the sphere 220 and does not exert any force on the sphere 220 .

[0052] According to an embodiment provided by the utility model, the first clamping plate 111 and the second clamping plate 112 are both arc-shaped plates that match the shape of the outer wall of the graphite tube 500, and the concave surfaces of the two arc-shaped plates are arranged opposite to each other. In this embodiment, the first clamping plate 111 and the second clamping plate 112 are both arc-shaped plates, and the bending state of the arc-shaped plates matches the shape of the outer wall of the graphite tube 500. The concave surfaces of the first clamping plate 111 and the second clamping plate 112 are arranged opposite to each other, and a clamping space 113 is formed between the two opposite concave surfaces, which can form an embracing clamping form for the graphite tube 500, increase the contact area with the graphite tube 500, and make the clamping work more stable and reliable. Moreover, the clamping jaws 110 composed of the arc-shaped plates can adapt to different types of graphite tubes 500, so that the application range of the graphite tube installation device is wider.

[0053] According to an embodiment provided by the utility model, the clamping assembly 100 further includes a positioning component 140, which is disposed on the supporting component 120, and is used to vertically position the axial direction of the injection hole 510. In this embodiment, during the process of the clamping assembly 100 clamping the graphite tube 500, in order to ensure that the injection hole 510 of the graphite tube 500 is consistent with the vertical state of the supporting component 120 after clamping, the positioning component 140 positions the injection hole 510, that is, after the staff controls the clamping jaws 110 to clamp the graphite tube 500, the injection hole 510 must correspond to the positioning component 140, so that it can be confirmed that the graphite tube 500 is clamped in place.

[0054] In this embodiment, after the injection hole 510 is positioned by the positioning component 140, it can ensure that the axial direction of the injection hole 510 is consistent with the vertical extension direction of the support component 120. Therefore, when the support component 120 produces an angular deviation in the vertical direction, the injection hole 510 also produces an angular deviation, thereby improving the accuracy of clamping the graphite tube 500 and the accuracy of the subsequent verticality detection during the installation process of the graphite tube 500.

[0055] According to an embodiment provided by the utility model, the positioning component 140 includes a first connecting rod 141 and a second connecting rod 142, the first connecting rod 141 and the second connecting rod 142 are both located above the clamp 110, one end of the first connecting rod 141 is connected to the first support plate 121, and the other end is provided with a first positioning rod 143, the second connecting rod 142 is connected to the second support plate 122, and the other end is provided with a second positioning rod 144, the first positioning rod 143 and the second positioning rod 144 are both arc-shaped rods, and the two arc-shaped rods enclose a positioning space 145, and the positioning space 145 is located above the injection hole 510 and aligned with the injection hole 510.

[0056] In this embodiment, the positioning component 140 is arranged at the lower end of the supporting component 120, located at the connecting position between the clamping jaw 110 and the supporting component 120, the first connecting rod 141 and the second connecting rod 142 of the positioning component 140 are arranged opposite to each other, and are respectively connected to the first supporting plate 121 and the second supporting plate 122, and the first positioning rod 143 and the second positioning rod 144 are respectively arranged at the ends close to the first connecting rod 141 and the second connecting rod 142, and the first positioning rod 143 and the second positioning rod 144 are both arc-shaped rods, and the positioning space 145 of the injection hole 510 is surrounded by the first positioning rod 143 and the second positioning rod 144, that is, after the clamping jaw 110 clamps the graphite tube 500, the injection hole 510 needs to face the positioning space 145. The first connecting rod 141 and the second connecting rod 142 can move synchronously with the first supporting plate 121 and the second supporting plate 122, that is, the first positioning rod 143 and the second positioning rod 144 gradually approach to limit the circular positioning space 145, and the circular positioning space 145 is aligned with the injection hole 510, indicating that the clamping jaws 110 clamp the graphite tube 500 in place.

[0057] In other embodiments, the positioning component 140 may also adopt other structures, such as a positioning sensor, which transmits infrared or laser signals and receives reflected signals to determine the axial verticality of the injection hole 510 when the jaws 110 initially clamp the graphite tube 500.

[0058] According to an embodiment provided by the utility model, the graphite tube installation device further includes an illumination lamp 400, which is arranged at the upper end of the support component 120. Compared with the prior art, when the graphite tube 500 is installed on the atomic absorption spectrometer, it must be illuminated by an external light source such as a flashlight, which is inconvenient to operate and affects work efficiency. In this embodiment, by arranging the illumination lamp 400 at the upper end of the support component 120 to provide a light source for illumination, the installation work is ensured to proceed smoothly and the work efficiency is improved.
