Dustproof sealing cover for spectrometer sample chamber

Abstract

This utility model relates to the field of spectrometer sample chamber technology and discloses a dustproof sealing cover for a spectrometer sample chamber. It includes a spectrometer body, a sample chamber on the top of the spectrometer body, a dustproof cover rotatably connected to one side of the spectrometer body, and a motion module on one side of the spectrometer body. This side of the spectrometer body is rotatably connected to one end of the dustproof cover via the motion module. This utility model, through the sliding connection of the rotating shaft within a fixed hinge and the setting of a pulling spring, allows the dustproof cover to perform a vertical lifting action at the initial opening stage. Only after it disengages from the sealing surface of the sample chamber and reaches a certain height can it automatically rotate and open under the action of the spring force. This avoids the instantaneous direct channel formed when a traditional sealing cover rotates directly, significantly slowing down the speed and flow of external air entering the sample chamber, thereby minimizing the disturbance of airflow to the molecular stability environment inside the sample chamber and providing a more reliable environmental guarantee for spectroscopic detection.

Description

Technical Field

[0001] This utility model belongs to the technical field of spectrometer sample chambers, and specifically relates to a dustproof sealing cover for a spectrometer sample chamber. Background Technology

[0002] The spectrometer sample chamber is an enclosed space in an optoelectronic measurement system used to fix and hold the sample to be measured. By optimizing the optical path and environmental control, it ensures that the sample is subjected to light excitation or signal collection under specific conditions.

[0003] In the current technology, the design of the sealing cover of the sample chamber in the use of current spectroscopic analysis instruments has a key impact on maintaining the stability of the detection environment.

[0004] However, existing sample chambers generally use direct rotating sealing covers. When these traditional sealing covers are opened, a momentary direct channel is formed between the cover and the sample chamber, and external air rushes into the sample chamber rapidly under the action of pressure difference.

[0005] Such sudden airflow disturbances can disrupt the molecular environment inside the sample chamber, destroying the stable detection atmosphere established in the early stages. Secondly, they can easily bring external dust particles directly into the optical detection path. These contaminants will adhere to the surface of precision optical components, which will not only increase background noise and reduce detection sensitivity, but also accelerate the aging of optical components, increasing maintenance frequency and usage costs. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dustproof sealing cover for the sample chamber of a spectrometer.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a dustproof sealing cover for a spectrometer sample chamber, comprising a spectrometer body, a sample chamber on the top of the spectrometer body, a dustproof cover rotatably connected to one side of the spectrometer body, a motion module on one side of the spectrometer body, and a motion module rotatably connected to one end of the dustproof cover via the motion module; a fixing module on the other side of the spectrometer body, and a fixing module engaging with the other end of the dustproof cover via the fixing module; the motion module comprises: a fixed hinge, one side of which is fixed to one side of the spectrometer body; a movable hinge, one side of which is fixed to one side of the dustproof cover; and a movable rotating shaft, the circumferential surface of which is fixed to the inner wall of the movable hinge, and the circumferential surface of the movable rotating shaft is slidably connected to the inner wall of the fixed hinge.

[0008] Preferably, the motion module further includes: a moving shaft, one side of which is fixed to one side of the moving hinge; a limiting slider, the limiting sliders being symmetrically distributed and fixed at both ends of the moving shaft, the surface of the limiting sliders being slidably connected to the inner wall of the fixed hinge; an L-shaped lifting member, the side of which is slidably connected to the inner wall of the fixed hinge, one end of which is in contact with one side of the moving hinge; a fixed shaft, one side of which is fixed to one side of the fixed hinge; and a pulling spring, the pulling springs being symmetrically distributed and snap-fitted to both ends of the fixed shaft, the other end of which is snap-fitted to both ends of the moving shaft.

[0009] Preferably, the fixed hinge member has a reserved swivel groove on its inner surface near the limiting slider, and the inner wall of the reserved swivel groove is in contact with the side of the limiting slider.

[0010] Preferably, a lifting spring is snapped onto one side of the parallel section of the L-shaped lifting member, and the other end of the lifting spring is snapped onto the inner wall of the fixed hinge member; the fixed hinge member has symmetrically formed limiting vertical grooves on its surface near the lifting spring, and a limiting vertical member is slidably connected to the inner wall of the limiting vertical groove, and one side of the limiting vertical member is fixed to the side of the L-shaped lifting member.

[0011] Preferably, the side of the L-shaped lifting member away from the lifting spring is provided as a reinforcing slope.

[0012] Preferably, the fixing module includes: a round-end column, one side of which is fixed to the inner surface of the dust cover, and a slot is formed on one side of the circumferential surface of the round-end column; a mounting component, one side of which is fixed to the inner surface of the spectrometer body; a J-shaped component, the surface of which is slidably connected to the inner wall of the mounting component; and a return spring, one end of which is fixed to the vertical section of the J-shaped component, and the other end of which is fixed to the inner wall of the mounting component.

[0013] Preferably, an auxiliary button is snapped onto one end of the J-shaped member, the area of ​​the auxiliary button is larger than the cross-sectional area of ​​the J-shaped member, and the side of the auxiliary button is slidably connected to the inner wall of the spectrometer body.

[0014] Preferably, the end of the round-end post near the J-shaped member is set as a round end, the end of the J-shaped member near the round-end post is set as a guide slope, and the end of the guide slope of the J-shaped member is in contact with the inner wall of the groove of the round-end post.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model, through the specific structure of the motion module, especially the sliding connection of the moving shaft in the fixed hinge and the setting of the pull spring, ensures that the dust cover must first perform a vertical lifting action when it is initially opened. Only after it is separated from the sealing surface of the sample chamber and reaches a certain height can it automatically rotate and open under the action of the spring force. This two-stage opening method of lifting first and then rotating avoids the instantaneous direct channel formed when the traditional sealing cover rotates directly, which significantly slows down the speed and flow of external air entering the sample chamber, thereby minimizing the disturbance of airflow to the molecular stability environment inside the sample chamber and providing a more reliable environmental guarantee for spectral detection.

[0017] 2. The configuration of the pull spring in the motion module of this utility model provides the driving force for automatic rotation and opening after the cover is raised, making the operation more convenient. After the cover is rotated to the position, the pull spring provides a self-locking effect to the cover, improving the stability of the equipment.

[0018] 3. This utility model, through the cooperation of the L-shaped lifting component and the lifting spring, as well as the sliding connection that restricts the slider in the reserved rotating groove, together guides and restricts the lifting of the dust cover. This ensures that when the lifting spring releases its elastic potential energy to lift the moving hinge and the dust cover upward after the fixed module is unlocked, the lifting motion is smooth and controllable, avoiding shaking or collision of the cover, improving the operating feel and the service life of the equipment.

[0019] 4. This utility model achieves automatic locking of the dust cover when it is closed by using a fixing module set on the other side of the spectrometer body, which utilizes the snap-fit ​​cooperation between the round end column and the J-shaped part under the action of the return spring, thus ensuring the tightness of the seal.

[0020] 5. This utility model, through the guide slope at the end of the J-shaped component and the round end design of the round end column, enables the closing process to be automatically completed by locking without additional operation. The auxiliary button allows the user to easily apply force to overcome the force of the reset spring, release the locking state, and open the cover. The structure is simple and effective, reduces the production cost of the equipment, and takes into account both the reliability of the seal and the ease of opening and closing operation.

[0039] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0041] Example 1:

[0042] refer to Figures 1-10 The dustproof sealing cover for the spectrometer sample chamber includes a spectrometer body 1, a sample chamber 101 on the top of the spectrometer body 1, a dustproof cover 102 rotatably connected to one side of the spectrometer body 1, a motion module 2 on one side of the spectrometer body 1, and a motion module 2 rotatably connected to one end of the dustproof cover 102 via the motion module 2; a fixing module 6 on the other side of the spectrometer body 1, and a fixing module 6 snapping into the other end of the dustproof cover 102 via the fixing module 6; the motion module 2 includes: a fixed hinge 206, one side of which is fixed to one side of the spectrometer body 1; a movable hinge 201, one side of which is fixed to one side of the dustproof cover 102; and a movable rotating shaft 203, the circumferential surface of which is fixed to the inner wall of the movable hinge 201, and the circumferential surface of the movable rotating shaft 203 is slidably connected to the inner wall of the fixed hinge 206.

[0043] Specifically, by setting the motion module 2 and the fixed module 6 on both sides of the spectrometer body 1 respectively, they together form the support and opening and closing system of the dust cover 102. This layout allows the dust cover 102 to move along a specific trajectory at one end through the motion module 2, and to reliably lock and release at the other end through the fixed module 6. This lays the structural foundation for realizing the core opening method of lifting first and then rotating, thus fundamentally different from the traditional direct rotation sealing cover, and aims to solve the problem of airflow disturbance when opening the cover.

[0044] The motion module 2 also includes: a moving shaft 202, one side of which is fixed to one side of a moving hinge 201; a limiting slider 204, which is symmetrically distributed and fixed at both ends of the moving shaft 203, and the surface of the limiting slider 204 is slidably connected to the inner wall of the fixed hinge 206; an L-shaped lifting member 205, the side of which is slidably connected to the inner wall of the fixed hinge 206, and one end of which is in contact with one side of the moving hinge 201; a fixed shaft 207, one side of which is fixed to one side of the fixed hinge 206; and a pulling spring 208, which is symmetrically distributed and snapped onto both ends of the fixed shaft 207, and the other end of which is snapped onto both ends of the moving shaft 202.

[0045] Specifically, through the coordinated action of the moving shaft 202, the limiting slider 204, the L-shaped lifting component 205, the fixed shaft 207, and the pulling spring 208, together with the core components such as the moving rotating shaft 203, the complete motion module 2 function is formed. After the dust cover 102 is lifted, the pulling spring 208 provides the driving force for automatic rotation and opening, and after rotating to the position, it makes the mechanism tend to stabilize, achieving a self-locking effect, which improves the convenience of operation and the stability of the equipment.

[0046] The fixed hinge 206 has a reserved rotary groove 3 on its inner surface near the limiting slider 204, and the inner wall of the reserved rotary groove 3 fits against the side of the limiting slider 204.

[0047] Specifically, the cooperation between the reserved rotary groove 3 and the limiting slider 204 provides precise guidance and movement space restriction for the sliding and rotation of the movable rotary shaft 203. The limiting slider 204 first restricts the rotation of the movable rotary shaft 203, so that the movable rotary shaft 203 rises with the movable hinge 201 pushed by the L-shaped lifting member 205. When the movable rotary shaft 203 rises to the predetermined position, the limiting slider 204 reaches the reserved rotary groove 3. The reserved rotary groove 3 provides rotation space for the limiting slider 204, so that the movable rotary shaft 203 loses the restriction of the limiting slider 204 and can rotate under the pull of the pull spring 208, ensuring the accuracy and controllability of the movement trajectory of the dust cover 102.

[0048] A lifting spring 4 is snapped onto one side of the parallel section of the L-shaped lifting member 205, and the other end of the lifting spring 4 is snapped onto the inner wall of the fixed hinge member 206. A limiting vertical groove 401 is symmetrically opened on the surface of the fixed hinge member 206 near the lifting spring 4. A limiting vertical member 402 is slidably connected to the inner wall of the limiting vertical groove 401, and one side of the limiting vertical member 402 is fixed to the side of the L-shaped lifting member 205.

[0049] The side of the L-shaped lifting member 205 away from the lifting spring 4 is set as a reinforcing slope 5.

[0050] Specifically, the lifting spring 4, the limiting vertical groove 401, the limiting vertical member 402, and the reinforcing inclined surface 5 of the L-shaped lifting member 205 together constitute the lifting execution and buffering mechanism. The lifting spring 4 provides the initial lifting force after the fixed module 6 is unlocked. The limiting vertical groove 401 and the limiting vertical member 402 ensure that the lifting process is a stable linear motion. The reinforcing inclined surface 5 enhances the strength of the contact area between the L-shaped lifting member 205 and the moving hinge member 201, ensuring the smoothness, reliability, and stability of the dust cover 102 during the lifting stage.

[0051] The fixing module 6 includes: a round-end post 601, one side of which is fixed to the inner surface of the dust cover 102, and a slot is provided on one side of the circumference of the round-end post 601; a mounting part 605, one side of which is fixed to the inner surface of the spectrometer body 1; a J-shaped part 602, the surface of which is slidably connected to the inner wall of the mounting part 605; and a return spring 603, one end of which is fixed to the vertical section of the J-shaped part 602, and the other end of which is fixed to the inner wall of the mounting part 605.

[0052] Specifically, the basic locking function of the fixing module 6 is formed by the cooperation of the round end post 601, the mounting part 605, the J-shaped part 602 and the return spring 603. The return spring 603 provides a continuous clamping force to the J-shaped part 602, so that it can automatically lock into the slot of the round end post 601, realizing automatic locking when the dust cover 102 is closed, and ensuring the tightness of the seal.

[0053] An auxiliary button 604 is snapped onto one end of the J-shaped member 602. The area of ​​the auxiliary button 604 is larger than the cross-sectional area of ​​the J-shaped member 602. The side of the auxiliary button 604 is slidably connected to the inner wall of the spectrometer body 1.

[0054] Specifically, by setting a larger auxiliary button 604, a user interface that facilitates the application of force is provided, making it easier and more convenient to press the J-shaped member 602 to overcome the return spring 603, thus improving the user experience.

[0055] The end of the round-end column 601 near the J-shaped member 602 is set as a round end, and the end of the J-shaped member 602 near the round-end column 601 is set as a guide slope 7. One end of the guide slope 7 of the J-shaped member 602 is in contact with the inner wall of the slot of the round-end column 601.

[0056] Specifically, by setting the end of the round-end post 601 near the J-shaped member 602 as a round end, and setting the corresponding end of the J-shaped member 602 as a guide slope 7, when the dust cover 102 is closed, the round-end post 601 can slide in along the guide slope 7 of the J-shaped member 602 by relying on its round end structure, and finally automatically complete the locking under the action of the return spring 603, thus realizing the automation of the closing process, eliminating the need for additional manual locking operations, and simplifying the usage steps.

[0057] Example 2:

[0058] refer to Figures 1-10 Staff members use the structure disclosed in this utility model in a precision analysis laboratory;

[0059] An iCAP7600 ICP spectrometer is performing routine testing of high-purity metal samples. Its top sample chamber 101 needs to be opened and closed frequently to hold the samples.

[0060] The dustproof sealing cover for the sample chamber of the spectrometer of this utility model is applied to this scenario. In the motion module 2 on one side of the spectrometer body 1, the fixed hinge 206 is fixed to the spectrometer housing by four M4 internal hex screws and is made of 6061 aluminum alloy; the movable hinge 201 is also made of aluminum alloy and is fixed to the side of the dustproof cover 102 by screws.

[0061] The rotating shaft 203 is a 5 mm diameter stainless steel shaft, with nylon limiting sliders 204 pressed at both ends. The sliders slide within the reserved groove 3 on the inner side of the fixed hinge 206. The groove is 5.2 mm wide and has a 0.1 mm gap to ensure smooth movement. The L-shaped lifting member 205 is made of 45# steel. The lifting spring 4, which is snapped onto the back of its vertical section, is a Japanese SWP-0.8-10 model with an initial pressure of 8 Newtons. The other end of the spring is snapped into the groove on the inner wall of the fixed hinge 206. The limiting vertical member 402 welded to the side of the L-shaped lifting member 205 is a 3 mm diameter stainless steel pin, which slides for 12 mm within the limiting vertical groove 401 of the fixed hinge 206.

[0062] The pull spring 208 is a MISUMI brand SCW2-5 model with a wire diameter of 0.5 mm. Its two ends are hooked to the fixed shaft 207 and the moving shaft 202, respectively. The fixed shaft 207 is a 4 mm diameter stainless steel rod fixed to the fixed hinge 206. On the other side of the spectrometer, the round-end post 601 of the fixing module 6 is made of POM plastic and is fixed to the inner side of the dust cover 102 with screws. Its surface groove depth is 1.5 mm. The mounting part 605 is an ABS injection molded part, fixed inside the spectrometer housing. The J-shaped part 602 is made of 65Mn spring steel with a nickel-plated surface. Its tail end is fitted with an auxiliary button 604 made of black nylon, with a diameter of 12 mm, protruding 2 mm from the housing surface. The return spring 603 is a stainless steel compression spring with an initial pressure of 5 Newtons.

[0063] When the operator needs to change the sample, press the auxiliary button 604 with your finger to push the J-shaped part 602 backward by 3 mm to release the locking of the round end post 601. At this time, the lifting spring 4 immediately pushes the L-shaped lifting part 205 upward, and the hinge 201 is activated by the reinforcing inclined surface 5 at its top, so that the dust cover 102 is first lifted vertically by 10 mm. This process completely avoids the instantaneous airflow channel formed by the traditional rotating opening. When the limiting slider 204 rises to the reserved rotating groove 3 position, the pulling spring 208 quickly pulls the moving shaft 202, which drives the dust cover 102 to automatically rotate and open to a 75-degree angle around the rotating shaft 203, so that the operator can put in the sample cup with a diameter of 30 mm.

[0064] When closing, simply rotate the dust cover 102 in the opposite direction. The round end of the cylindrical member 601 slides down along the guide slope 7 at the front end of the J-shaped member 602, compressing the reset spring 603 until the slot is aligned. Then the J-shaped member 602 automatically springs back and locks. At the same time, the dust cover 102 presses down the L-shaped lifting member 205 to recompress the lifting spring 4, thus completing the seal.

[0065] The entire opening and closing process effectively prevents external dust from entering the optical path, ensuring that the spectrometer's detection accuracy remains at a stable level of ±0.1 nanometers.

[0066] The working principle of this utility model:

[0067] Step 1: In the closed state, the two ends of the dust cover 102 are fixed by the motion module 2 and the fixing module 6 respectively.

[0068] On one side of the fixed module 6, the slot on the round end post 601 is tightly locked by the end of the J-shaped member 602. The return spring 603 continuously provides clamping force to the J-shaped member 602 to ensure reliable locking, thereby ensuring that the dust cover 102 and the sealing surface of the sample chamber 101 are tightly fitted to form an effective seal.

[0069] On one side of the motion module 2, the pull spring 208 is in a stretched state, storing elastic potential energy, and has a tendency to pull the moving shaft 202 and the moving hinge 201 to rotate. However, since the limiting slider 204 is restricted within the vertical slide of the fixed hinge 206, the rotation of the moving shaft 203 is prevented, so that the entire cover is stably locked in the closed position.

[0070] Step 2: The operator presses the auxiliary button 604. The button pushes the J-shaped member 602 backward against the force of the return spring 603, causing its end to disengage from the slot of the round end post 601, thus releasing the lock on that side of the dust cover 102.

[0071] Once the locking of the fixed module 6 is released, the lifting spring 4 in the motion module 2 releases its elastic potential energy, and its elastic force pushes the L-shaped lifting member 205 upward. The L-shaped lifting member 205 pushes the movable hinge member 201, thereby driving the entire dust cover 102 to perform a vertical upward movement.

[0072] The limiting vertical member 402 slides within the limiting vertical groove 401, ensuring the stability and stability of the L-shaped lifting member 205 and the entire lifting process without shaking. At the same time, the limiting sliders 204 at both ends of the moving rotating shaft 203 slide upward within the vertical slide of the fixed hinge member 206, continuing to prevent the cover from rotating.

[0073] This vertical lifting action causes the sealing surface of the dust cover 102 to first separate parallel from the opening of the sample chamber 101, avoiding the wedge-shaped gap formed when a traditional hinge rotates directly. External air can only enter through this slowly increasing, uniformly narrow gap, which greatly slows down the airflow speed and effectively prevents the airflow from drastically disturbing the molecular stability environment inside the sample chamber.

[0074] Step 3: When the dust cover 102 is raised to the predetermined height, the limiting slider 204 slides precisely to the position of the reserved rotating groove 3. This groove provides rotation space for the limiting slider 204, releasing the rotation restriction on the moving rotating shaft 203.

[0075] The previously stored-energy spring 208 immediately releases its energy, pulling the moving shaft 202 and driving the moving hinge 201 and the moving rotating shaft 203 to rotate around the fixed hinge 206.

[0076] Driven by the pull spring 208, the dust cover 102 automatically and smoothly rotates and opens from its raised position to the fully open state, making it convenient for users to place or remove samples.

[0077] Step 4: The operator rotates the dust cover 102 in the opposite direction to return it to a vertical position. During the closing process, the round end of the round end post 601 on the side of the fixing module 6 will first contact the guide slope 7 at the front end of the J-shaped member 602. As the cover is pressed down, the round end post 601 will press the J-shaped member 602 along the guide slope 7, causing it to retract backward against the force of the return spring 603 until the slot of the round end post 601 moves to the end position of the J-shaped member 602. At this time, the return spring 603 pushes the J-shaped member 602 forward quickly, automatically locking it into the slot to complete the locking.

[0078] As the pressure is applied to close, the dust cover 102 presses the L-shaped lifting member 205 downward via the movable hinge 201, compressing the lifting spring 4 and storing energy for the next opening. The limiting slider 204 also slides back to the vertical slide, relocking the movable shaft 203, ready for the next cycle.

[0079] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
