Description

Technical Field

[0001] This disclosure relates to the field of waveguide technology, specifically to a waveguide with anti-loosening function. Background Technology

[0002] Waveguides are an important component of microwave measurement and transmission systems, and their connection stability directly affects the quality of microwave transmission and the accuracy of measurement.

[0003] Existing waveguide connection methods typically involve abutting the ends of two waveguides together, with each waveguide end having a threaded structure. These threads connect multiple waveguides to form a new waveguide of the desired length. In this method, each waveguide usually has an internal thread at one end and an external thread at the other. Due to the weight and relatively small size of the waveguides themselves, coupled with the limited length of the threads, stripping and detachment can occur at the connection points over time, leading to unstable waveguide connections.

[0004] Alternatively, a connecting fastener can be installed between the two waveguides, connecting them together via the fastener and threaded structure. This connection method securely links the two waveguides, but because the fastener requires threaded holes to connect them, its outer diameter is relatively large. This results in the waveguides occupying a significant amount of installation space, and interference waves may occur during microwave transmission, potentially affecting microwave measurements.

[0005] Therefore, there is an urgent need in the field for a new type of waveguide rod that can increase connection strength while also ensuring uniform waveguide performance. Summary of the Invention

[0006] To address the technical problems existing in current waveguide connection methods and achieve the technical effects of secure connection between different waveguides, convenient installation and operation, and no change in outer diameter after connection, this invention provides a waveguide with anti-loosening function.

[0007] The technical solution adopted by the present invention to solve its technical problem is: to provide a waveguide rod with anti-loosening function, which includes at least a waveguide rod body, one end of the waveguide rod body is provided with a stepped protrusion structure, and the other end of the waveguide rod body is provided with a stepped groove structure. The stepped protrusion structure and the stepped groove structure are matched and configured to detachably connect different waveguide rods through the stepped protrusion structure and the stepped groove structure.

[0008] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function has a stepped protrusion structure at one end of the waveguide rod body whose dimensions gradually decrease along the direction away from the waveguide rod body.

[0009] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function has a stepped groove structure at the other end of the waveguide rod body whose dimensions gradually decrease along the direction close to the waveguide rod body.

[0010] According to at least one embodiment of the waveguide rod with anti-loosening function, the stepped protrusion structure at one end of the waveguide rod body includes a first protrusion and a second protrusion, wherein the outer diameter of the first protrusion is smaller than the outer diameter of the second protrusion; correspondingly, the stepped groove structure at the other end of the waveguide rod body includes a first groove and a second groove, wherein the inner diameter of the first groove is smaller than the inner diameter of the second groove; the first protrusion matches the first groove, and the second protrusion matches the second groove.

[0011] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function is provided, wherein the first protrusion is configured with an external thread structure, the first groove is configured with an internal thread structure, and the first protrusion and the first groove are fixedly connected to the waveguide rod through the thread structure.

[0012] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function is provided on the second protrusion, a first anti-loosening hole / first anti-loosening groove is provided on the second groove, and a second anti-loosening hole / second anti-loosening groove is correspondingly provided on the second groove. The waveguide rod is prevented from rotating by aligning the first anti-loosening hole / first anti-loosening groove with the second anti-loosening hole / second anti-loosening groove and inserting anti-loosening pins into the first anti-loosening hole / first anti-loosening groove and the second anti-loosening hole / second anti-loosening groove.

[0013] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function is provided, wherein the first anti-loosening hole / first anti-loosening groove is configured as a threaded hole / threaded groove, and the anti-loosening pin is configured as a threaded pin.

[0014] According to at least one embodiment of the present disclosure, a waveguide rod with anti-loosening function is provided, wherein both the first anti-loosening hole and the second anti-loosening hole are round holes, and the anti-loosening pin is a round rod.

[0015] According to at least one embodiment of the present disclosure, a waveguide rod with an anti-loosening function is provided, wherein the first anti-loosening hole is a circular hole and the second anti-loosening groove is a U-shaped groove.

[0016] According to at least one embodiment of the waveguide rod with anti-loosening function, the stepped protrusion structure at one end of the waveguide rod body further includes a third protrusion, which is configured as a wedge-shaped surface, and the outer diameter of the third protrusion is larger than the outer diameter of the second protrusion; correspondingly, the stepped groove structure at the other end of the waveguide rod body further includes a third groove, which is configured as a wedge-shaped surface, and the inner diameter of the third groove is greater than or equal to the inner diameter of the second groove; the wedge-shaped surfaces of the third protrusion and the third groove enable different waveguide rods to be tightly connected.

[0017] The advantages of this disclosure compared to the prior art are as follows:

[0018] 1. This disclosure achieves a detachable connection between different waveguides by setting a stepped protrusion structure at one end of the waveguide body and a stepped groove structure at the other end, with the two matched together, thus overcoming the problem of unstable connection of existing waveguides.

[0019] 2. By setting the first protrusion as an external thread structure and the first groove as an internal thread structure, the different waveguide rods are fixedly connected through the thread structure, thereby enhancing the connection strength.

[0020] 3. This disclosure effectively prevents the waveguide rod from rotating during use by setting a first anti-loosening hole / first anti-loosening groove and a second anti-loosening hole / second anti-loosening groove on the second protrusion and the second groove respectively, and by inserting an anti-loosening pin, thereby further ensuring the firmness of the connection between different waveguide rods.

[0021] 4. This disclosure achieves an interference wedge connection through the wedge-shaped surface design of the third protrusion and the third groove, which facilitates the alignment of the first anti-loosening hole / first anti-loosening groove and the second anti-loosening hole / second anti-loosening groove, allowing the anti-loosening pin to be quickly inserted. This ensures a firm connection of the waveguide rod while avoiding a change in the outer diameter of the waveguide rod, thus reducing the space occupied by the entire waveguide rod in the equipment installation.

[0022] 5. This disclosure employs various methods, such as threaded connection, combination of anti-loosening holes and anti-loosening pins, and interference wedge fit, to achieve a firm connection between different waveguide rods. The installation and operation are convenient, and the outer diameter of the connected waveguide rods has no change structure, which effectively avoids the interference waves generated by the connecting fasteners in the prior art during microwave transmission, and improves the accuracy of microwave measurement.

[0038] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0039] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1-2 As shown, this disclosure provides a waveguide rod with anti-loosening function, including at least a waveguide rod body 1. One end of the waveguide rod body 1 is provided with a stepped protrusion structure 2, and the other end of the waveguide rod body 1 is provided with a stepped groove structure 3. The stepped protrusion structure 2 and the stepped groove structure 3 are matched and configured to detachably connect different waveguide rods through the stepped protrusion structure 2 and the stepped groove structure 3.

[0042] In practical applications, due to the large size of the container containing the medium to be measured, a long waveguide is required. Different waveguides can be connected to measure the medium information within the container at the target depth. In this disclosure, one end of the waveguide body 1 is configured as a stepped groove structure 3, and the other end as a stepped protrusion structure 2. The stepped groove structure 3 and the stepped protrusion structure 2 can be cleverly combined, making the outer diameter of the newly connected waveguide close to or the same as the outer diameter of the initially connected segmented waveguides. Compared to the prior art, which adds a connecting fastener between two waveguides, causing the outer surface to protrude and resulting in interference waves during measurement, this disclosure achieves uniform waveguide effect simply through the clever connection of the waveguides themselves.

[0043] like Figure 3 As shown, when the waveguide rods of this disclosure are connected to form new longer waveguide rods, the first and last ends of the waveguide rods have only a stepped protrusion structure 2 (the end connected to the meter head) or only a stepped groove structure 3 (the end that is in direct contact with the medium inside the container).

[0044] To quickly install two waveguides together, mounting slots 4 are provided at both ends of the waveguide body 1 near the stepped protrusion structure 2 and the stepped groove structure 3, so that installation tools such as wrenches can be clamped in the mounting slots 4 to quickly install multiple waveguides into a new waveguide of the required length.

[0045] Preferably, the waveguide body 1 is cylindrical and made of metal, possessing good waveguide performance and mechanical strength. The length of the waveguide body 1 can be designed in different specifications according to actual application requirements, typically ranging from 200mm to 1000mm, with a diameter from 10mm to 50mm. The surface of the waveguide body 1 is precision-machined, with a surface roughness not exceeding Ra1.6μm to ensure stable waveguide performance.

[0046] The stepped protrusion 2 at one end of the waveguide body 1 gradually decreases in size along the direction away from the waveguide body 1. Specifically, the stepped protrusion 2 decreases in size sequentially outward from the waveguide body 1, forming a multi-level stepped structure. This design allows for precise alignment during connection and provides sufficient contact area, enhancing connection strength.

[0047] The stepped groove structure 3 at the other end of the waveguide body 1 gradually decreases in size along the direction close to the waveguide body 1. The stepped groove structure 3 decreases in size sequentially from the outside to the inside along the axial direction of the waveguide body 1, forming a multi-level stepped groove that perfectly matches the stepped protrusion structure 2. This corresponding design ensures precise fit when different waveguides are connected, and the outer diameter of the new waveguide after precise fit is the same as the outer diameter of multiple original waveguide segments, preventing diameter changes at the connection point. This results in more stable and uniform waveguide information when measuring medium information.

[0048] The stepped protrusion structure 2 at one end of the waveguide body 1 includes a first protrusion 21 and a second protrusion 22, wherein the outer diameter of the first protrusion 21 is smaller than the outer diameter of the second protrusion 22. The first protrusion 21 is located at the outermost end of the stepped protrusion structure 2, and the second protrusion 22 is located between the first protrusion 21 and the waveguide body 1. The typical outer diameter of the first protrusion 21 is 15mm to 25mm, and the typical outer diameter of the second protrusion 22 is 25mm to 35mm.

[0049] Correspondingly, the stepped groove structure 3 at the other end of the waveguide rod body 1 includes a first groove 31 and a second groove 32, wherein the inner diameter of the first groove 31 is smaller than the inner diameter of the second groove 32. The first groove 31 is located at the innermost end of the stepped groove structure 3, and the second groove 32 is located on the side of the first groove 31 away from the waveguide rod body 1. The inner diameter of the first groove 31 matches the outer diameter of the first protrusion 21, typically ranging from 15.05 mm to 25.05 mm, with a 0.05 mm assembly clearance; the inner diameter of the second groove 32 matches the outer diameter of the second protrusion 22, typically ranging from 25.05 mm to 35.05 mm, also with an appropriate assembly clearance.

[0050] It should be noted that the first protrusion 21 matches the first groove 31, and the second protrusion 22 matches the second groove 32. When the two waveguide rods are connected, the stepped protrusion structure 2 of one waveguide rod is inserted into the stepped groove structure 3 of the other waveguide rod, the first protrusion 21 is inserted into the first groove 31, and the second protrusion 22 is inserted into the second groove 32, forming a stable connection.

[0051] In addition, in order to ensure the smooth transition between different stages of the multi-stage stepped structure of the stepped groove structure 3 and the stepped protrusion structure 2, the transition connection of the multi-stage stepped structure can be set as a smooth inclined surface, such as a wedge-shaped surface. This will ensure that there are no gaps at the connection of different waveguide rods and that the connection stability is good.

[0052] Specifically, the first protrusion 21 is configured with an external thread structure, and the first groove 31 is configured with an internal thread structure. The first protrusion 21 and the first groove 31 are fixedly connected to each other through the threaded structure. The external and internal threads adopt standard metric threads with a pitch of 1.5 mm and a thread length of 10 mm to 15 mm. Through the threaded connection, the two waveguides can be tightly connected in the axial direction to prevent axial loosening.

[0053] Furthermore, a first anti-loosening hole 221 is provided on the second protrusion 22, and a corresponding second anti-loosening hole is provided on the second groove 32. By aligning the first anti-loosening hole 221 and the second anti-loosening hole and inserting an anti-loosening pin 5 into the first anti-loosening hole 221 and the second anti-loosening hole, the waveguide rod is prevented from rotating. The diameters of the first anti-loosening hole 221 and the second anti-loosening hole can be the same, typically 3mm to 5mm, and the central axis of the hole is perpendicular to the axis of the waveguide rod body 1. The diameter of the anti-loosening pin 5 matches the diameter of the anti-loosening hole, slightly smaller by 0.05mm to 0.1mm, to facilitate insertion and removal. Alternatively, the diameter of the second anti-loosening hole can be designed to be slightly larger than the diameter of the first anti-loosening hole 221, thereby facilitating the quick insertion of the anti-loosening pin 5 into the first anti-loosening hole 221 and the second anti-loosening hole.

[0054] Specifically, the first anti-loosening hole 221 can be a threaded hole, and the anti-loosening pin 5 can be a threaded pin. The threaded hole uses an M4 internal thread, and the threaded pin uses a matching M4 external thread. By screwing the threaded pin into the threaded hole, axial or radial movement of the waveguide rod can be prevented, thus more securely locking the two waveguide rods and preventing loosening due to vibration during use. Since the inner diameter of the second groove 32 matches the outer diameter of the second protrusion 22, the second anti-loosening hole provided on the second groove 32 can be a threaded hole or a smooth hole. After the threaded pin is inserted into the first anti-loosening hole 221 and the second anti-loosening hole, its end abuts against the outside of the second anti-loosening hole, and the end size is larger than the outer diameter of the second anti-loosening hole, thereby preventing axial or radial movement of the waveguide rod during use.

[0055] Alternatively, the first anti-loosening hole 221 can be configured as a blind hole, also known as a first anti-loosening groove, which can be specifically configured as a threaded groove. In this case, the second anti-loosening hole can be a threaded hole or a smooth hole. After the threaded pin is inserted into the first anti-loosening hole 221 and the second anti-loosening hole, the end cap abuts against or outside the second anti-loosening hole, and the size of the end cap is slightly larger than or close to the outer diameter of the second anti-loosening hole, thereby preventing the waveguide rod from moving axially or radially during use. To achieve uniformity of the waveguide after connection, it is preferable that the length of the threaded pin matches the depth of the first and second anti-loosening holes, that is, while preventing the waveguide rod from moving axially or radially, a new waveguide rod outer diameter-free structure is also achieved, resulting in a firm connection and stable waveguide performance.

[0056] Alternatively, the second protrusion 22 can be configured with an external thread structure, and the second groove 32 with an internal thread structure. The second protrusion 22 and the second groove 32 can be fixedly connected between different waveguide rods through the threaded structure. The external and internal threads adopt standard metric threads with a pitch of 1.5 mm and a thread length of 10 mm to 15 mm. Through the threaded connection structure, the two waveguide rods can be tightly connected axially, preventing axial loosening. In this case, the first protrusion 21 and the first groove 31 can be smooth cylindrical structures or threaded structures.

[0057] The stepped protrusion structure 2 at one end of the waveguide body 1 also includes a third protrusion 23, which is configured as a wedge-shaped surface. The outer diameter of the third protrusion 23 is larger than that of the second protrusion 22. The third protrusion 23 is located between the second protrusion 22 and the waveguide body 1, and its outer diameter is typically 35mm to 45mm. The inclination angle of the wedge-shaped surface is 5° to 10°, which can produce a wedge-tightening effect during connection.

[0058] Correspondingly, the stepped groove structure 3 at the other end of the waveguide body 1 also includes a third groove 33. The third groove 33 is configured with a wedge-shaped surface, and its inner diameter is larger than that of the second groove 32. The third groove 33 is located on the side of the second groove 32 away from the waveguide body 1, and its inner diameter matches the outer diameter of the third protrusion 23, typically ranging from 35.05 mm to 45.05 mm. The wedge angle of the third groove 33 is completely consistent with the wedge angle of the third protrusion 23.

[0059] The wedge-shaped surfaces of the third protrusion 23 and the third groove 33 enable a tight connection between the different waveguide rods. When two waveguide rods are connected and tightened by threads, radial pressure is generated between the wedge-shaped surfaces, further enhancing the stability and sealing of the connection and effectively preventing loosening.

[0060] Since the third protrusion 23 and the third groove 33 in this disclosure are connected by an interference fit through a wedge-shaped surface, the maximum inner diameter of the third groove 33 is set to match the minimum outer diameter of the third protrusion 23 (for example, the maximum inner diameter of the third groove 33 is slightly greater than or equal to the minimum outer diameter of the third protrusion 23, so that the third protrusion 23 can enter the third groove 33, and the third protrusion 23 and the third groove 33 are tightly connected as the waveguide rod is turned). Alternatively, the inner diameter of the third groove 33 can be set to be close to the inner diameter of the second groove 32 (the minimum inner diameter of the third groove 33 is slightly greater than or equal to the inner diameter of the second groove 32). This makes the connection between the third protrusion 23 and the third groove 33 tighter, and the connection between the two waveguide rods more robust and stable.

[0061] In practical use, align the stepped protrusion structure 2 of one waveguide rod with the stepped groove structure 3 of the other waveguide rod, gently insert and rotate to engage the external thread of the first protrusion 21 with the internal thread of the first groove 31. Continue rotating until the two waveguide rods are tightly connected. At this point, the second protrusion 22 is fully inserted into the second groove 32, and the wedge-shaped surface of the third protrusion 23 is tightly fitted with the wedge-shaped surface of the third groove 33. Then align the first anti-loosening hole 221 with the second anti-loosening hole, insert the threaded pin and tighten it to complete the anti-loosening fixation.

[0062] Alternatively, the stepped groove structure 3 and stepped protrusion structure 2 of this disclosure can also be provided with a fourth groove and a fourth protrusion. In this case, the first protrusion 21 and the second protrusion 22 can be configured as external thread structures, the first groove 31 and the second groove 32 as internal thread structures, the third protrusion 23 and the third groove 33 as cylindrical structures, and the fourth protrusion and the fourth groove as wedge-shaped surfaces. Of course, the connection points between the first protrusion 21 and the second protrusion 22, the second protrusion 22 and the third protrusion 23, and the third protrusion 23 and the fourth protrusion can be configured as wedge-shaped surfaces, smoothly connected curved surfaces, right-angle structures, or other structures. Correspondingly, the connection points between the first groove 31 and the second groove 32, the second groove 32 and the third groove 33, and the third groove 33 and the fourth groove can be configured as wedge-shaped surfaces, smoothly connected curved surfaces, right-angle structures, or other structures. This design can enhance the strength of the connection points.

[0063] This waveguide rod structure, with its anti-loosening function, is rationally designed and has a firm and reliable connection. It effectively prevents loosening due to vibration or other external forces during use, ensuring the stability and reliability of the waveguide system. Furthermore, the structure is easy to disassemble, facilitating maintenance and replacement.

[0064] Example 2

[0065] A waveguide rod with anti-loosening function has the same basic structure as Embodiment 1, except that: the first anti-loosening hole 221 and the second anti-loosening hole are both round holes, and the anti-loosening pin 5 is a round rod.

[0066] Specifically, both the first and second anti-loosening holes 221 and 221 have a diameter of 4mm and smooth, threadless walls. The anti-loosening pin 5 is a cylindrical metal rod with a diameter of 3.95mm and a length of 30mm, slightly longer than the total depth of the two anti-loosening holes. One end of the anti-loosening pin 5 has a stop to prevent it from being fully inserted into the hole; the other end may have an elastic snap-lock structure that self-locks after insertion to prevent it from falling out.

[0067] This design simplifies the anti-loosening structure, eliminating the need for threaded connections and making installation and disassembly more convenient, suitable for applications requiring frequent assembly and disassembly. The round rod-type anti-loosening pin 5 can be quickly inserted and removed, saving operation time, while still effectively preventing the waveguide rod from rotating radially.

[0068] Example 3

[0069] like Figure 4-6 As shown, a waveguide rod with anti-loosening function has the same basic structure as Embodiment 1, except that: the first anti-loosening hole 221 is set as a round hole, and the second anti-loosening groove 321 is set as a U-shaped groove.

[0070] Specifically, the first anti-loosening hole 221 is a round hole with a diameter of 4mm and a depth of 10mm. The second anti-loosening groove 321 is a U-shaped groove with a width of 4.5mm, a depth of 5mm, and a length of 10mm. The anti-loosening pin 5 is a cylindrical metal rod with a diameter of 3.95mm and a length of 15mm.

[0071] like Figure 4-6 As shown, when the two waveguide rods are connected, the first anti-loosening hole 221 and the second anti-loosening groove 321 partially overlap, forming a channel for the insertion of the anti-loosening pin 5. After the anti-loosening pin 5 is inserted, part of it is located in the first anti-loosening hole 221 and the other part is located in the second anti-loosening groove 321, effectively restricting the relative rotation between the two waveguide rods.

[0072] In this disclosure, by setting the third protrusion 23 and the third groove 33 as a wedge-shaped structure, it is easy to align the first anti-loosening hole 221 and the second anti-loosening groove 321. Combined with the second anti-loosening groove 321 being set as an open U-shaped groove (at this time, the U-shaped groove is set on the second groove and the third groove), even if the angle alignment of the two waveguide rods is not precise, the interference fit can quickly align the first anti-loosening hole 221 and the second anti-loosening groove 321, thereby quickly inserting the anti-loosening pin 5, increasing the fault tolerance of the operation. At the same time, the structure of the U-shaped groove makes the anti-loosening pin 5 easier to insert and remove, further improving the convenience of operation.

[0073] like Figure 6As shown, after the two waveguide rods are connected by matching the first protrusion 21 with the first groove 31 and the second protrusion 22 with the second groove 32, there is still a connection gap in the first groove 31. Then, the two waveguide rods are tightened by clamping the mounting groove 4 with a wrench. Combined with the wedge-shaped surface design of the third protrusion 23 and the third groove 33, the interference fit makes the first protrusion 21 and the first groove 31 match and connect tightly. Furthermore, the outer surface of the new waveguide rod after connection has no protrusion or diameter change structure, thereby achieving stable connection and uniform waveguide.

[0074] It should be noted that Embodiment 1, Embodiment 2, and Embodiment 3 are all types of waveguide rods with anti-loosening function.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0076] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
