Description

Technical Field

[0001] The present application relates to the field of industrial detection, in particular to the field of slurry detection and analysis, and more particularly to a window assembly, a probe including the window assembly, and an XRF analyzer including the probe. Background Art

[0002] It is known that in the mining industry, slurry analysis is very important. This is because slurry directly affects multiple aspects such as mineral processing efficiency, resource utilization, and environmental protection. As the main means of analyzing slurry, an analyzer such as an XRF analyzer is generally used, which usually includes a multi-element probe. Specifically, the multi-element probe is inserted into a container storing the slurry, and at least the portion of the multi-element probe containing the window assembly is completely inserted and immersed in the slurry. Then, light (e.g., X-rays) emitted by a light source (e.g., an X-ray light source) disposed inside the probe is irradiated from the inside of the probe to the slurry stored in the container through a light-transmitting window member in the window assembly. Under the irradiation of the light emitted by the light source, the electrons of the atoms of the substances constituting the slurry are moved from low-energy orbits to high-energy orbits, and after a period of time, they are de-excited from the high-energy orbits to low-energy orbits. As a result, fluorescence is emitted from the slurry. These fluorescent lights are transmitted from the interior of the container to the interior of the probe via the window member of the window assembly and are detected by a detector (e.g., a solids detector) located within the probe. The detector converts the received optical signals into electrical signals and transmits these signals to an analysis module. Based on the received electrical signals, the analysis module analyzes the solids content, particle size distribution, mineral composition, solution pH, and other parameters of the slurry. By accurately measuring and analyzing these parameters of the slurry, it is possible to optimize the mineral processing process, improve ore recovery, reduce energy consumption, and minimize environmental pollution.

[0003] Generally speaking, the probe's window assembly consists of two separate window components, commonly referred to as the inner window and outer window. When the window assembly is mounted on the probe and the portion of the probe, including the window assembly, is immersed in the ore slurry, the outer window comes into direct contact with the ore slurry. However, the inner window, located inside the probe's housing, is shielded from direct contact. Since the outer window is constantly exposed to the harsh working environment of ore slurry during operation, dirt and substances that may affect detection accuracy will accumulate on the outer window over time. Therefore, the outer window needs to be replaced after a period of use.

[0004] Figure 8 A perspective view of a probe including a conventional window assembly is shown. Figure 9 Shows the view from one direction Figure 8A perspective view of a conventional window assembly is shown. Figure 10 Shown from another direction Figure 8 A perspective view of a conventional window assembly is shown. Figure 11 FIG. 4 shows a cross-sectional view of the existing window assembly. Figure 8 As shown, the probe P0 has a housing C0 for housing components such as a light source and a detector, and the window assembly A0 is connected to the housing C0 at one end of the probe P0. Figures 9 to 11 As shown, the window assembly A0 includes a base portion 100, an outer window portion A100 and an inner window portion A200. The outer window portion A100 and the inner window portion A200 are attached together in the axial direction, and a plurality of (eight) bolt holes 200 are formed at prescribed intervals in the circumferential direction of the inner window portion A200. By screwing bolts into these bolt holes 200, the outer window portion A100 and the inner window portion A200 are fixedly connected to the base portion 100 together. In addition, a pair of sleeves 300 with built-in threads are formed on the surface of the inner window portion A200 on the side away from the outer window portion A100. After completing the assembly of the window assembly A0, the sleeve 300 is aligned with the threaded hole of the housing C0 of the probe P0, and the bolts are screwed into the threaded hole and the sleeve 300. Thus, the window assembly A0 is connected to the probe P0.

[0005] On the other hand, when the window components of the outer window portion A100 are to be replaced, the probe P0 needs to be removed from the ore slurry, and the window assembly A0 needs to be disassembled from the probe P0, and then the front window portion A100 needs to be disassembled from the window assembly A0. Generally speaking, the disassembly action is performed above the container in which the ore slurry is stored. Specifically, it is necessary to first unscrew the two bolts from the sleeve 300, disassemble the window assembly A0 from the probe P0, and then loosen and remove the eight bolts connecting the outer window portion A100 and the inner window portion A200 to the base portion 100, thereby separating the outer window portion A100 from the base portion 100 and the inner window portion A200, and replacing the window components of the outer window portion A100.

[0006] However, such disassembly is cumbersome and requires additional tools (e.g., a screwdriver). Using a screwdriver to loosen and remove the bolts is both time-consuming and labor-intensive. Furthermore, there is a risk that the loosened bolts may fall directly into the ore slurry due to careless operation.

[0007] Furthermore, detection and analysis work may be performed at a considerable height. The floor on which workers stand may have a mesh floor. Therefore, when using a screwdriver to loosen and remove a bolt, there is a risk that the loosened bolt could fall through the mesh due to careless handling.

[0008] In order to avoid the above situation, operators often move to other environments to replace window components, which takes a lot of time and greatly prolongs the replacement time of window components, thereby reducing work efficiency. Utility Model Content

[0009] The present application is formed to solve the above-mentioned technical problems, and its purpose is to provide a window assembly and a probe including the window assembly, which can save the energy and time spent on disassembly work while avoiding time delays caused by disassembly errors.

[0010] The present application provides a window assembly, characterized by comprising:

[0011] a first window portion having a first window member;

[0012] a second window portion having a second window member, the second window portion being arranged side by side with the first window portion in one direction; and

[0013] A bayonet-type locking mechanism is configured to be switchable between a locked state and an unlocked state. In the locked state, the first window portion and the second window portion are fixed. In the unlocked state, the first window portion and the second window portion can move relative to each other and can be separated.

[0014] According to the window assembly described in this technical solution, by using a bayonet-type locking mechanism to connect the first window portion and the second window portion, the first window portion and the second window portion can be fixed and separated with a simple structure. Specifically, when the window components of the first window portion and / or the second window portion need to be replaced, the first window portion and the second window portion can be separated without the use of external tools, simply by changing the bayonet-type locking mechanism from a locked state to an unlocked state. Therefore, compared with the bolt connection method used in the prior art, it can significantly save the time and effort spent on disassembly work, and there is no risk of small disassembled parts being easily lost.

[0015] Optionally, the bayonet locking mechanism includes a pressing member and a recess, one of the recess and the pressing member being formed in one of the first window portion and the second window portion. The other of the recess and the pressing member is configured to: in the locked state, engage with the one of the recess and the pressing member to prevent relative rotation of the first window portion and the second window portion; and in the unlocked state, disengage from the one of the recess and the pressing member to allow relative rotation of the first window portion and the second window portion.

[0016] According to the window assembly described in this technical solution, by engaging and releasing the pressing member with the recessed portion, the first window portion and the second window portion can be fixed and removed with a simple structure without using additional tools.

[0017] Alternatively, the other of the recess and the pressing member is formed in the other of the first window and the second window.

[0018] According to the window assembly described in this technical solution, the connection and disassembly between the first window portion and the second window portion can be easily achieved without the aid of additional tools.

[0019] Optionally, one of the first window portion and the second window portion is connected to another component.

[0020] Optionally, the first window portion and the second window portion abut against each other in the one direction. The second window portion is located closer to the other component than the first window portion in the one direction and is connected to the other component. One of the recess and the pressing member is formed in the second window portion.

[0021] Optionally, the first window portion further comprises a first window frame for receiving the first window member, the second window portion further comprises a second window frame for receiving the second window member, and one of the recess and the pressing member is formed in the second window frame.

[0022] Optionally, the first window portion includes a snap-fit ​​mechanism, and the first window component is fixed to the first window portion via the snap-fit ​​mechanism. The second window portion includes a bolt fixing mechanism, and the second window component is fixed to the second window portion via the bolt fixing mechanism.

[0023] According to the window assembly described in this technical solution, the first window member and the second window member are fixed to the first window portion and the second window portion, respectively, using a snap-fit ​​mechanism and a bolt fixing structure. Because completely different fixing mechanisms are used, when performing replacement operations, the operator can quickly distinguish between the two and identify the window portion where the window member to be replaced is located. Furthermore, as mentioned above, since the first window member of the first window portion is easily contaminated with dirt, etc., it needs to be replaced frequently. To this end, in the window assembly described in this technical solution, the first window member is fixed to the first window portion using a snap-fit ​​mechanism that is easy to disassemble. This allows the operator to remove the snap-fit ​​mechanism and replace the first window member without the use of additional tools. Furthermore, since the second window portion is located away from the external environment relative to the first window portion, the second window member in the second window portion is less likely to be contaminated with dirt, etc. Therefore, fixing the second window member to the second window portion using a bolt fixing mechanism can improve the stability of the second window member's fixation; in other words, it can be more securely fixed. Furthermore, by fixing the second window member to the second window portion using the bolt fixing mechanism, the sealing performance of the second window portion can be improved.

[0024] Optionally, the snap-fit ​​mechanism is a first window frame that receives the first window member, the first window frame comprising a pair of first frames that engage with each other to clamp the first window member. The second window portion comprises a second window frame that receives the second window member, the second window frame comprising a pair of second frames, the second window member being clamped between the pair of second frames and fixed to the second window portion by the bolt fixing mechanism.

[0025] According to the window assembly described in this technical solution, by respectively providing a pair of first frames and a pair of second frames to fix the first window member and the second window member, the first window member and the second window member can be firmly fixed to prevent the first window member and the second window member from being misaligned.

[0026] Optionally, the bolt fixing mechanism includes a pair of fixing frames and bolts, and the pair of fixing frames are connected by the bolts to clamp the pair of second frames and the second window member.

[0027] According to the window assembly described in this technical solution, it is possible to securely fix the second window member while ensuring a certain degree of sealing.

[0028] Optionally, one of the pair of fixing frames is formed in a cylindrical shape, and a threaded portion is formed along the circumferential direction on at least a portion of a side surface of the one of the pair of fixing frames, and the second window portion is connected to the other member via the threaded portion.

[0029] According to the window assembly described in this technical solution, the window assembly can be connected and fixed to another component as an external component without using additional parts, and the window assembly can be disassembled without using additional tools.

[0030] Optionally, a foreign matter sensing portion is further included, the foreign matter sensing portion being disposed between the first window portion and the second window portion and sensing whether foreign matter has leaked from either the first window portion or the second window portion.

[0031] The window assembly according to the technical solution can sense whether foreign matter has invaded the interior of the window assembly from the outside of the probe, thereby preventing the probe from being damaged due to working in a state where foreign matter has invaded.

[0032] Optionally, the second window portion further includes a second annular member, and the second annular member is disposed in a gap between the second window member and the pair of fixing frames.

[0033] According to the window assembly described in this technical solution, the space between the second window member and the fixing frame can be sealed, thereby preventing foreign matter from intruding into the interior of the window assembly from the outside.

[0034] Optionally, it further includes a base portion, which abuts against the first window portion.

[0035] Optionally, the first window portion further includes a first annular member, and the first annular member is arranged in a gap between the first window member and the base portion.

[0036] According to the window assembly described in this technical solution, the first window portion (specifically, the first window member) and the base portion can be sealed, thereby preventing foreign matter from invading the interior of the window assembly from the outside.

[0037] Optionally, a protrusion is formed on the base portion, and the protrusion protrudes from the base portion toward a side opposite to the first window portion relative to the base portion.

[0038] According to the window assembly described in this technical solution, the window assembly can be conveniently installed and disassembled by operating the protruding portion.

[0039] Optionally, the recess is formed in the second window portion, and the pressing member is formed in the base portion.

[0040] Optionally, the second window portion is formed with at least one pair of lugs spaced apart from each other to form the recess therebetween. The base portion is further formed with a recess configured to allow the press member to be pressed into the recess. In the locked state, the press member is at least partially exposed from the recess to engage with the recess. In the unlocked state, the press member is pressed into the recess to disengage the press member from the recess.

[0041] Optionally, the bayonet lock mechanism further comprises a displacement limiting member configured to limit the displacement of the first window portion and the second window portion in the direction.

[0042] According to the technical solution, the first window portion and the second window portion can be prevented from being separated due to the displacement in the axial direction.

[0043] In addition, the present application further provides a probe comprising the window assembly according to any one of the technical solutions and a housing for accommodating the window assembly.

[0044] In addition, the present application further provides an XRF analyzer comprising the probe.

[0045] According to the window assembly, the probe and the XRF analyzer, the time and energy spent on disassembly can be saved, and the time delay caused by disassembly failure can be avoided. BRIEF DESCRIPTION OF DRAWINGS

[0093] Below, refer to Figures 1 to 7 , the main structure of the window assembly and the probe including the window assembly according to one embodiment of the present application is described.

[0094] Figure 1 FIG1 shows a schematic diagram of the lower half of a probe P including a window assembly A according to an embodiment of the present application. Figure 1As shown, probe P is a multi-element probe used, for example, in mining applications, to be immersed in slurry and analyzed. It includes a housing C, a window assembly A, and various components used for detection and analysis. Housing C forms the outer shield of probe P, preventing foreign matter from entering the interior of probe P from the outside. The various components used for detection and analysis include a light source element and a solid-state detector. Window assembly A is mounted to the portion of housing C located at one end of probe P and includes a transparent member, such as a window, through which light passes. Specifically, when probe P is immersed in slurry, the end of probe P to which window assembly A is mounted is completely immersed in the slurry. At this point, under the action of electrical power, the light source element emits light, such as X-rays, which pass through the window of window assembly A and irradiate the slurry outside probe P. Under the irradiation of X-rays, electrons in the atoms of the substance constituting the slurry transition from low-energy orbits to high-energy orbits, and then return to low-energy orbits after a certain period of time, thereby generating fluorescence. The generated fluorescence is emitted from the slurry and passes through the window of the window assembly A and is received by a solid detector arranged inside the housing C of the probe P. The solid detector converts the received light information into an electrical signal and further transmits it to the analytical instrument for analysis.

[0095] As described above, the window assembly A allows light from the light source element to be irradiated from the inside of the probe P to the outside and allows external light to enter the inside of the probe P. Figure 2 A perspective view of a window assembly A according to an embodiment of the present application viewed from one direction is shown. Figure 3 FIG. 2 shows a perspective view of the window assembly A of this embodiment viewed from another direction. Figure 2 and Figure 3 Both show the window assembly A in a fully assembled state. Figure 4 A cross-sectional view of the window assembly A of this embodiment cut along the radial direction is shown. Figure 5 An exploded view of the window assembly A of this embodiment is shown. Figure 6 FIG1 shows an exploded view of the window assembly A of this embodiment after the first window portion A1 and the second window portion A2 are assembled. Figure 7 FIG. 1 shows an exploded view of the first window portion A1 constituting a part of the window assembly A of this embodiment. Figures 2 to 8 , the main structure of the window assembly A of one embodiment of the present application is described in detail.

[0096] like Figure 5 As shown, the window assembly A mainly includes a base portion 1, a pair of first frames (i.e., first window frames) 2, a first window member 3, a pushing member 4, a pair of second frames (i.e., second window frames) 5, a pair of fixing frames 6, a second window member 7, a bolt 8, a foreign object sensing member 9 and a limiting member (displacement limiting member) 10.

[0097] The base portion 1 is as follows Figure 2 As shown, the base 1 is provided on the housing C of the probe P in a snap-fit ​​manner, for example, with one side facing the slurry when the probe P is immersed in the slurry. Preferably, the base 1 is made of a material having good corrosion resistance to the slurry. The base 1 is an annular member having a central hole O formed in its radial center portion and extending through the base 1 in the axial direction. In addition, as shown Figure 2 As shown, a pair of protrusions 12 can be formed on the edge portion of the outer surface of the base portion 1, and the pair of protrusions 12 allow the user to rotate the base portion 1 and even the entire window assembly A, so as to remove the window assembly A from the housing C of the probe P. This point will be explained in detail in conjunction with the second frame 5.

[0098] In addition, if Figure 5 As shown, on the surface of the base portion 1 on the side close to the inside of the probe P, a plurality of (three in this embodiment) protrusions 13 are formed at intervals along the circumferential direction, and a plurality of (four in this embodiment) screw holes are formed in each protrusion 13. Each protrusion 13 is used to install the limiting member 10. In particular, among the three protrusions 13, Figure 5 The convex block portions 13 on the upper side and the left side are all formed continuously along the circumferential direction, and the three convex block portions 13 are formed on the upper side and the left side. Figure 5 The convex portion 13 on the right side is not formed continuously along the circumferential direction. Figure 4 and Figure 5 As shown in FIG. 1 , a groove G is formed at approximately the middle of the circumference of the projection 13 , and a pressing member 14 is provided at the groove G so as to be movable relative to the groove G. Specifically, as shown in FIG. Figure 5 As shown, a spring is provided in the groove G, and the pressing member 14 is sleeved on the spring. Thus, when the pressing member 14 is not pressed, at least a portion of the pressing member 14 is located outside the groove G relative to the groove G. In other words, at least a portion of the pressing member 14 protrudes to the outside relative to the groove G, and the spring is in a relaxed state. On the other hand, if the pressing member 14 is pressed, the pressing member 14 is pressed as a whole into the groove G under the action of the pressing force, and the spring is in a compressed state at this time. More specifically, the pressing member 14 includes a pressing portion 14A and a block portion 14B connected to the pressing portion 14A. In particular, as shown in FIG. Figure 4 and Figure 5As shown, the block portion 14B extends radially inward relative to the protrusion portion 13 to a position closer to the central hole O than the protrusion portion 13. As will be described later, when the pressing member 14 is not pressed, at least a portion of the block portion 14B protrudes outward from the groove G. Therefore, it engages with the recessed portion 17 formed between the pair of claw portions 16 described later, thereby restricting the relative rotation of the claw portions 16. It should be noted that although the present embodiment shows a case where only one protrusion portion 13 is formed with a groove G and a corresponding pressing member 14 is provided, the present invention is not limited to this. For example, grooves may be formed on all or two protrusion portions 13 and pressing members 14 may be provided accordingly.

[0099] In this embodiment, the groove 13, the pressing member 14, and the recess 17 together constitute a bayonet-type locking mechanism. Through the cooperation of the above-mentioned components, the open-type locking mechanism can switch between a locked state and an unlocked state. Specifically, when the block 14B of the pressing member 14 is engaged with the recess 17, the bayonet-type locking mechanism is in a locked state, and the first window portion A1 and the second window portion A2 cannot be displaced relative to each other. When the block 14B of the pressing member 14 and the recess 17 are released, the bayonet-type locking mechanism is in an unlocked state, and the first window portion A1 and the second window portion A2 can rotate relative to each other.

[0100] In addition, if Figure 4 and Figure 5 As shown, an annular groove B is formed along the entire circumference of the radially outer surface of the base portion 1, and a base-side O-ring R0 is fitted into this annular groove B. By fitting the base-side O-ring R0 into the annular groove B, when the assembled window assembly A is mounted on the housing of the probe P, the base-side O-ring provides a seal, thereby preventing foreign matter from intruding into the interior of the window assembly A through the gap between the housing C and the window assembly A.

[0101] The above describes the main structure of the base portion 1 included in the window assembly A of the present embodiment. However, it should be noted that the base portion 1 is not an essential component, and as long as the technical effect of the window assembly A of the present embodiment can be achieved, the window assembly A may not include the base portion 1. In addition, in the present embodiment, the case where a pair of protrusions 12 are provided on the surface of the base portion 1 on the slurry side is described as an example, but the invention is not limited thereto. That is, as long as the base portion 1 can be rotated relative to the housing C, the base portion 1 may not include a pair of protrusions 12. In addition, in the case where the window assembly A does not include the base portion 1, the above-mentioned protrusion portion 13, the groove G, and the pressing member 14 may be provided on the housing C of the probe P.

[0102] The pair of first frames 2 , the first window member 3 , and the pressing member 4 together constitute a first window portion A1 of the window assembly A of the present embodiment. Figure 7 An exploded view of the first window portion A1 including a pair of frames 2 , a first window member 3 , and a pressing member 4 is shown.

[0103] The pair of first frames 2 is an example of a snap-fit ​​mechanism, including a first front frame 2A located closer to the base 1 in the assembled state and a first rear frame 2B located farther from the base 1 than the first front frame 2A in the assembled state. Figure 5 As shown, the first front frame 2A and the first rear frame 2B are both annular members that are open in the axial direction, and have flanges protruding in the axial direction formed on their respective circumferential edges. The first window member 3 is a light-transmitting member with a certain degree of transparency (transmittance), such as a glass sheet or a polyester film (mylar). Figure 5 and Figure 7 As shown, the first front frame 2A, the first window member 3, and the first rear frame 2B are arranged approximately parallel to each other, spaced apart in the axial direction. In this arrangement, the first front frame 2A and the first rear frame 2B are simultaneously brought into proximity with the first window member 3, thereby sandwiching the first window member 3 between the first and rear frames 2A, i.e., the pair of first frames 2. More specifically, the first front frame 2A and the first rear frame 2B are both made of an elastic material, and the outer diameter of the first rear frame 2B is slightly larger than the inner diameter of the first front frame 2A but smaller than the outer diameter of the first front frame 2A. Thus, when the first front frame 2A and the first rear frame 2B simultaneously approach and abut the first window member 3, a certain amount of pushing force causes the first rear frame 2B to engage with the first front frame 2A, thereby securely sandwiching the first window member 3 between the first front frame 2A and the first rear frame 2B. The above description uses the example of a case where the outer diameter of the first rear frame 2B is slightly larger than the inner diameter of the first front frame 2A. However, this is not limiting. Alternatively, the outer diameter of the first front frame 2A may be slightly larger than the inner diameter of the second rear frame 2B but smaller than the outer diameter of the second rear frame 2B. Since the pair of first frames 2 are configured as a snap-fit ​​mechanism as described above, they are easily disassembled. Therefore, if the first window member 3 needs to be replaced, the snap-fit ​​mechanism can be manually separated without the use of additional tools, thereby allowing the first window member 3 to be replaced.

[0104] The pushing member 4 is also formed as an annular member, and its outer diameter is smaller than the inner diameter of the first rear frame 2B. In this way, the pushing member 4 pushes the first window member 3 toward the base portion 1 from the rear side of the first rear frame 2B, and the first window member 3 can be firmly fixed between the pushing member 4 and the base portion 1, thereby further fixing the first window member 3. In addition, as Figure 5 As shown, one side of the pushing member 4 abuts against the first window member 3, and the other side abuts against the foreign matter sensing member 9, thereby achieving the fixation of the pushing member 4. Preferably, as Figure 4 As shown, a first frame side O-ring (i.e., a first annular member) R1 can be provided in the gap between the pushing member 4 and / or the base portion 1 and the first window member 3. In this way, the first frame side O-ring R1 can seal the pushing member 4 and / or the base portion 1 and the first window member 3. As a result, it is possible to prevent foreign matter from reaching the first window member 3 from the outside through the gap between the base portion 1 and the first window member 3 and contaminating the first window member 3, and it is possible to prevent foreign matter from reaching the first window member 3 through the gap between the pushing member 4 and the first window member 3 and contaminating the first window member 3. It should be noted that the "abutment" mentioned above refers to a relationship in which the surfaces of the two components are in contact with each other, rather than being connected.

[0105] The pair of second frames 5, the pair of fixing frames 6, the second window member 7 and the bolts 8 together constitute the second window portion A2 of the window assembly A of this embodiment. More specifically, the pair of fixing frames 6 and the bolts 8 constitute an example of a bolt fixing mechanism. In this embodiment, as Figure 5 As shown, the second window portion A2 and the first window portion A1 are arranged side by side in one direction, i.e., in the axial direction, with a gap therebetween, so that the first window member 3 and the second window member 7 are arranged in the axial direction, so that the sheet-like first window member 3 and the sheet-like second window member 7 are parallel to each other in a manner that their respective main surfaces are orthogonal to the axial direction, or the sheet-like first window member 3 and the sheet-like second window member 7 are opposite to each other in a manner that their respective main surfaces are basically parallel, or the sheet-like first window member 3 and the sheet-like second window member 7 are opposite to each other in a manner that their planes can intersect. However, it should be noted that when the sheet-like first window member 3 and the sheet-like second window member 7 are opposite to each other in a manner that their planes can intersect, it is necessary to ensure that light can be irradiated from the outside of the window assembly A to the inside or from the inside to the outside. Similar to the first window member 3, the second window member 7 is a light-transmitting member with a certain transparency (transmittance), such as a glass sheet or polyester film (mylar). As Figure 5 As shown, the second front frame 5A, the second window member 7, and the second rear frame 5B are spaced apart in the axial direction and arranged substantially parallel to each other. In this arrangement, the second front frame 5A and the second rear frame 5B are simultaneously brought close to the second window member 7, so that the second window member 7 is sandwiched between the second front frame 5A and the second rear frame 5B, that is, between the pair of second frames 5.

[0106] The pair of second frames 5 includes a second front frame 5A located closer to the first window portion A1 in the assembled state and a second rear frame 5B located farther from the first window portion A2 relative to the second front frame 5A in the assembled state. Figure 5As shown, similar to the first front frame 2A and the first rear frame 2B, the second front frame 5A and the second rear frame 5B are also formed as annular members opened in the axial direction. Figure 4 and Figure 5 As shown, a flange protruding toward the second rear frame 5B is formed on the circumferential edge of the second front frame 5A, and a threaded portion 15 extending along the entire circumference and a plurality of pairs (three pairs in this embodiment) of dog portions 16 are formed on the flange.

[0107] As the threaded portion 15, for example, a three-start thread can be used, more specifically, a three-start ACME thread can be used. Corresponding to the threaded portion 15 formed on the circumferential edge of the second front frame 5A, a threaded portion is also provided on the housing C of the probe P, which is another component, or other components of the probe P. In this way, the second front frame 5A can be connected to the other component by a threaded connection. More specifically, the assembled window assembly A including the second front frame 5A can be connected to the other component by a threaded connection, thereby securing the window assembly A to the probe P. Furthermore, since the window assembly A is directly connected to the other component by a threaded connection, no unnecessary other components are generated when the window assembly A is removed from the other component. This prevents the other components used for connection from falling or being lost due to the removal of the window assembly A when the window assembly A is connected to the other component via other components. It should be noted that the "other component" mentioned in this application refers to a component other than the window assembly A.

[0108] The claw portions 16 are provided corresponding to the aforementioned protrusions 13. In this embodiment, since there are three protrusions 13, the number of pairs of claw portions 16 is correspondingly three. Each pair of claw portions 16 includes two claw portions 16 spaced apart circumferentially, with the gap between the two claw portions 16 forming a recess 17. As described above, the recess 17 is capable of engaging with the block portion 14B of the pressing member 14 corresponding to the groove G formed in the middle of one of the protrusions 13 on the base 1. Specifically, to engage the recess 17 with the block portion 14B of the pressing member 14, the pressing member 14 is first pressed until the block portion 14B of the pressing member 14 is completely inserted into the groove G. Then, after the second front frame 5A abuts the base 1, the pressure on the pressing member 14 is released, allowing the block portion 14 to at least partially emerge from the groove G. This completes the engagement of the recess 17 with the block 14. In this case, due to the engagement of the recess 17 with the block 14, the second front frame 5A cannot rotate circumferentially, thereby securing the second window portion A2 and, consequently, all parts of the window assembly A except the base 1. Furthermore, while this embodiment illustrates an example in which the number of pairs of claws 16 corresponds to the number of protrusions 13, and each pair of claws 16 is formed with a recess 17, this is not limiting. For example, the number of pairs of claws 16 may correspond to the number of protrusions 13 having grooves G and pressing members 14 formed therein. Alternatively, rather than providing claws 16 in accordance with the number of protrusions 13, only one pair of claws 16 may be provided, with a recess 17 formed between the pair. In short, any appropriate deformation can be made as long as the recessed portions 17 of at least one pair of claw portions 16 can be engaged with at least one pressing member 14 .

[0109] Preferably, if Figure 4 and Figure 5 As shown, a second frame-side O-ring (i.e., a second annular member) R2 is interposed between the second window member 7 and the second front frame 5A and / or the second rear frame 5B. In other words, preferably, the second frame-side O-ring (second annular member) R2 is disposed in the gap between the second window member 7 and the second front frame 5A and / or the second rear frame 5B. In this manner, the second frame-side O-ring R2 seals the second window member 7 against the second front frame 5A and / or the second rear frame 5B, thereby preventing foreign matter from reaching the second window member 7 through the gap between the second window member 7 and the second front frame 5A and / or the second rear frame 5B and contaminating the second window member 7.

[0110] A pair of fixing frames 6 Figure 4As shown, the front fixing frame 6A is arranged radially outside the second front frame 5A and the second rear frame 5B, and includes a front fixing frame 6A located axially forward of the second front frame 5A and a rear fixing frame 6B located axially rearward of the second rear frame 5B. Figure 5 As shown, a plurality of (eight in this embodiment) threaded holes for screwing the screw 8 therethrough are formed at regular intervals on the circumference of the front fixing frame 6A and the rear fixing frame 6B. In this way, when assembling the second window portion A2, after the second window member 7 is sandwiched between the second front frame 5A and the second rear frame 5B, the front fixing frame 6A and the rear fixing frame 6B clamp the second front frame 5A and the second rear frame 5B from both sides in the axial direction, and then the screw 8 is screwed into the above-mentioned threaded holes, thereby completing the assembly of the second window portion A2. The above description uses the combination of a pair of fixing frames 6 and screw 8 as an example to illustrate the screw fixing mechanism, but is not limited to this. For example, it is also possible to not include a pair of fixing frames 6, but to form a plurality of threaded holes on the second front frame 5A and the second rear frame 5B, and directly screw the screw 8 into these threaded holes, so that the second window member 7 can be fixed by screw connection.

[0111] The limiting member 10 is used to limit the axial movement of the claw portion 16 relative to the bump portion 13. Figure 5 As shown in FIG. 1 , in this embodiment, three position-limiting members 10 are provided corresponding to the number of the protrusions 13 . The position-limiting members 10 have the same strip shape as the protrusions 13 and have a plurality of screw holes. Figure 6 As shown, by aligning the screw holes of the limiting member 10 with the screw holes of the protruding block 13 and screwing the screws in, each limiting member 10 is fixed to the corresponding protruding block 13. In particular, the radial dimension of the limiting member 10 is designed so that when the recessed portion 17 of the pawl portion 16 is engaged with the block portion 14B of the pressing member 14, it at least partially overlaps with the pawl portion 16 in the radial direction (refer to Figure 3 As a result, when the second front frame 5A attempts to move axially away from the base portion 1, at least a portion of the protruding claw portion 16 is blocked by the limiting member 10 and cannot move further. This effectively limits the axial movement of the protruding claw portion 16, the second front frame 5A, and even the entire second window portion A2.

[0112] The foreign matter sensing member 9 is a member for sensing foreign matter that invades the window assembly A from the outside. Figures 3 to 6As shown, the foreign object sensing component 9 is axially sandwiched between the first window portion A1 and the second window portion A2. Specifically, the foreign object sensing component 9 is axially arranged between the pushing member 4 and the second front side frame 5A. It should be noted that when the first window portion A1 does not include the pushing member 4, the foreign object sensing component 9 is axially arranged between the first rear side frame 2B and the second front side frame 5A. The foreign object sensing component 9 is formed by performing processing such as punching on a circuit substrate printed with a sensing pattern. Specifically, an intermediate hole 9A is formed in the central part of the foreign object sensing component 9 by, for example, punching, etc., and the intermediate hole 9A is formed to ensure the continuity of the light path from the outside to the inside or from the inside to the outside. In addition, three strip holes 9B are formed in the portion of the foreign object sensing component 9 corresponding to the protrusion portion 13 formed on the base portion 1, and the protrusion portion 13 is inserted into the strip holes 9B. When a foreign object invades the interior of the probe P from the outside and touches the sensing pattern of the foreign object sensing component 9, the foreign object sensing component 9 can sense the presence of the foreign object and send a corresponding signal to the control unit of the probe P, thereby notifying the user that a foreign object has invaded. After receiving the notification, the user can decide whether to continue using the probe P for detection according to the actual situation. In this way, it is possible to avoid the situation where the probe P continues to work and is damaged when a foreign object invades. The above description uses the foreign object sensing component 9 as an example of a component that senses whether a foreign object exists, but is not limited to this. The foreign object sensing component 9 can also be a humidity sensing component that senses the surrounding humidity. By sensing the surrounding humidity, it can also be determined whether a foreign object has invaded the probe P.

[0113] The window assembly A described in this embodiment differs from the prior art, in which the rear window portion (i.e., the second window portion) is fixed to the base portion via bolts. In this embodiment, a bayonet-type locking mechanism is used to connect the second window portion A2 to the base portion 1 via a bayonet connection. This allows the bayonet-type locking mechanism to be changed from a locked state to an unlocked state, such as by pressing, allowing the first window portion A1 and the second window portion A2 to rotate relative to each other. This relative rotation causes the recess 17 and the pressing member 17 to circumferentially shift, while also causing the protruding claw portion 16 and the limiting member 10 to circumferentially shift, thereby separating the first window portion A1 from the second window portion A2. On the other hand, as described above, in the prior art, the front window portion (i.e., the first window portion) and the rear window portion (i.e., the second window portion) are bonded together and connected to the base portion via bolts. To replace the first window member in the front window section or the first window portion, the bolts must be removed from the threaded holes using a screwdriver or other tool before the first window portion can be separated from the second window portion. In this situation, the removed bolts are prone to falling and being lost. Especially when working at height or in an environment with a certain height, if the floor has a meshed surface, the tiny bolts can easily fall through the mesh. This significantly increases the time required to replace the window member and reduces work efficiency. Furthermore, to avoid this, workers must temporarily leave the work site and travel to another environment, such as a factory, to replace the window member, which also increases replacement time and reduces work efficiency. In contrast, in this embodiment, since the second window portion A2 is directly connected to the base portion 1 via the bayonet-type locking mechanism, there are no extra bolts or other tiny parts required to connect the two when removing the second window portion A2 (and the first window portion A1) from the base portion 1, thus preventing this problem. Therefore, the replacement time of window member can be shortened significantly. In addition, compared with bolt connection, the snap connection based on the bayonet type locking mechanism is easy to disassemble, therefore, can also save disassembly time.

[0114] In addition, in the present embodiment, a threaded portion 15 extending along the entire circumference is formed on the surface of the circumferential edge of the front fixing frame 6A in the pair of fixing frames 6 of the second window portion A2. The threaded portion 15 is threadedly connected to the threaded portion of another component (for example, the housing C) provided on the probe P, so that the entire window assembly A can be quickly and firmly fixed to the probe P. In this way, compared with the use of independent bolts and nuts to connect the window assembly A and the probe P in the prior art, it is possible to save loading and unloading time, reduce the difficulty of loading and unloading, and avoid the occurrence of situations such as the loss of independent bolts and nuts during disassembly in the prior art. However, it should be noted that the present invention can also use the connection method in the prior art to fix the window assembly A toward the probe P. However, compared with the prior art, the connection method adopted in this embodiment is a more preferred solution. In addition, when a pair of fixing frames 6 are not included, a threaded portion 15 extending along the entire circumference can be formed on the surface of the circumferential edge of the second front side frame 6A of a pair of second frames 2. By threading the threaded portion 15 with the threaded portion of another component provided on the probe P, a simple connection can also be achieved.

[0115] Furthermore, in the above embodiment, a case where a portion of the bayonet-type locking mechanism, namely the pressing member 14 and the groove 16, is formed in the base portion 1, and another portion, namely the recess 17, is formed in the second window portion A2 (in this case, the recess 17 is configured as one of the recess 17 and the pressing member 14, and the second window portion A2 is configured as one of the first window portion A1 and the second window portion A2) is described as an example, but the present invention is not limited to this. For example, in a case where the base portion 1 is not included, a portion of the bayonet-type locking mechanism may be formed in the first window portion A1, and another portion may be formed in the second window portion A2. Specifically, the pressing member 14 is formed in the first window portion A1, and the recess 17 is formed in the second window portion A2. In this case, the pressing member 14 constitutes one of the pressing member 14 and the recess 17, the first window portion A1 constitutes one of the first window portion A1 and the second window portion A2, the recess 17 constitutes the other of the pressing member 14 and the recess 17, and the second window portion A2 constitutes the other of the first window portion A1 and the second window portion A2. In the case of being set to the above-mentioned structure, when in a locked state, the pressing member 14 formed on the first window portion A1 engages with the recess 17 formed on the second window portion A2 so that the first window portion A1 and the second window portion A2 cannot rotate with each other. On the other hand, when in an unlocked state, the engagement between the pressing member 14 formed on the first window portion A1 and the recess 17 formed on the second window portion A2 is released so that the first window portion A1 and the second window portion A2 can rotate with each other and separate. In this way, there is no need to disassemble multiple (for example, eight) bolts as in the prior art, and the replacement of the first window member 3 of the first window portion A1 can be completed quickly without the help of additional tools. In addition, when the base portion 1 is included, the recessed portion 17 may be formed in the base portion 1 , and the pressing member 14 and the groove 16 may be formed in the second window portion A2 .

[0116] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
