Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic testing equipment technology, specifically to a lightweight ultrasonic C-scan probe quick-change interface. Background Technology
[0002] The lightweight ultrasonic C-scan probe quick-change interface is the core component in ultrasonic testing equipment that enables rapid connection between the probe and the main unit. Its main function is to stably connect the ultrasonic probe (including transducer, signal transmission module, etc.) to the testing main unit through standardized mechanical and electrical interfaces, while supporting quick disassembly and assembly to adapt to probes with different testing needs.
[0003] Traditional ultrasonic probe interfaces are mostly machined from a single metal block, which has the following prominent problems: First, the overall structure is thick and heavy (the wall thickness often exceeds 5mm), increasing the overall weight of the probe and easily causing operator fatigue during prolonged hand-held operation; second, the positioning and locking mechanisms rely on bolts or threaded connections, requiring tools for disassembly and assembly, which is time-consuming (a single disassembly or assembly takes more than 30 seconds), seriously affecting detection efficiency; third, the lack of a guiding and limiting structure makes it easy for misalignment during insertion to cause wear of the probe pins or poor electrical contact. Therefore, there is an urgent need for a quick-change probe interface that combines lightweight design, rapid disassembly and assembly, and high-precision guidance. Utility Model Content
[0004] The purpose of this invention is to provide a lightweight quick-change interface for an ultrasound C-scan probe. Through structural optimization design, it solves the problems of heavy weight, low disassembly and assembly efficiency, and insufficient guiding accuracy of traditional interfaces, thereby achieving rapid probe replacement and stable connection.
[0005] The technical solution provided by this utility model is a lightweight ultrasound C-scan probe quick-change interface, including a probe connection part and an interface seat. The interface seat and the probe connection part are detachably connected through a quick-disassembly connection structure, which includes a positioning mechanism and a quick-locking mechanism.
[0006] The interface base is made of lightweight material, and its main structure is a thin-walled frame with reinforcing ribs inside.
[0007] The positioning mechanism includes a plug interface disposed on the end face of the interface seat, the plug interface having an elastic stylus assembly inside, and a stylus hole correspondingly opened on the end face of the probe connection part.
[0008] The quick-lock mechanism includes an elastic buckle disposed on one side of the interface seat and a corresponding slot opened on the probe connection part. The elastic buckle achieves engagement or disengagement with the slot through elastic deformation.
[0009] As a preferred embodiment of this utility model, the lightweight material is aluminum alloy or carbon fiber composite, and the wall thickness of the thin-walled frame is 1-3mm.
[0010] As a preferred embodiment of this utility model, the reinforcing ribs are mesh-like or honeycomb-like structures, distributed radially along the frame.
[0011] As a preferred embodiment of this utility model, the elastic stylus assembly consists of multiple beryllium copper styluses evenly distributed along the circumference within the insertion interface, and the height of the elastic stylus assembly is less than the height of the insertion interface. One end of the elastic stylus assembly is electrically connected to the signal line of the ultrasonic testing equipment, and the other end is inserted through the stylus hole of the probe connection part.
[0012] As a preferred embodiment of this utility model, a guide pin is provided on one side of the insertion interface to restrict the insertion direction, and a corresponding guide groove is provided at the guide pin of the probe connection part, with the guide pin and the guide groove having a clearance fit.
[0013] As a preferred technical solution of this utility model, the elastic buckle includes an integrally formed pressing part, a connecting arm and a snap-fit part. The pressing part is exposed on the side of the interface seat, and the inner side of the pressing part is rotatably connected to the interface seat. The inner side of the connecting arm is provided with a V-shaped spring sheet. The end of the snap-fit part is provided with a barb, and the barb is interference-fitted with the groove of the snap-fit slot.
[0014] As a preferred technical solution of this utility model, the outer side of the probe connection part is provided with a reinforcing cylinder that wraps around the front end of the interface seat, and the slot is formed on the reinforcing cylinder.
[0015] As a preferred embodiment of this utility model, the connecting end faces of the probe connection part and the interface seat are provided with sealing grooves, and O-rings are embedded in the sealing grooves. The O-rings are made of fluororubber or silicone rubber.
[0016] The advantages of this utility model compared with the prior art are as follows:
[0017] 1. Balance between lightweight and high strength: The interface seat is made of aluminum alloy or carbon fiber composite material to form a thin-walled frame (wall thickness 1-3mm), combined with grid-like / honeycomb reinforcing ribs. While reducing the weight by 40%-60%, the structural optimization ensures impact resistance and deformation resistance, effectively reducing the operator's hand burden.
[0018] 2. Quick disassembly and high reliability: The elastic buckle drives the V-shaped spring sheet to deform through the pressing part, realizing one-handed operation for snapping and separating (single disassembly and assembly time < 5 seconds). The interference fit design of the barb and the slot avoids accidental loosening and improves the reliability of use.
[0019] 3. High-precision guidance and stable connection: The clearance fit between the guide pin and the guide groove (0.1-0.3mm) ensures the axial alignment accuracy of the probe and the interface, avoiding wear or poor contact caused by the stylus misalignment; the circumferentially evenly distributed design of the beryllium copper elastic stylus assembly (number ≥6) realizes the stable transmission of multi-channel signals.
[0020] 4. Enhanced environmental adaptability: The reinforcing sleeve wraps around the front end of the interface seat to protect the slot from external wear; the fluororubber / silicone rubber O-ring fills the end face sealing groove, which can still maintain a good seal in dusty, oily or humid environments (tested to have no leakage under 1 meter water pressure).

[0030] Example 1:
[0031] As per the instruction manual Figure 1-5 As shown, a lightweight ultrasound C-scan probe quick-change interface includes a probe connection part 1 and an interface seat 2. The interface seat 2 and the probe connection part 1 are detachably connected through a quick-release connection structure, which includes a positioning mechanism and a quick-locking mechanism.
[0032] In this utility model, the interface seat 2 is made of lightweight material, and its main structure is a thin-walled frame with reinforcing ribs 3 inside the frame. The lightweight material is aluminum alloy, the wall thickness of the thin-walled frame is 1-3mm, and the reinforcing ribs 3 are a grid or honeycomb structure distributed radially along the frame.
[0033] In this utility model, the positioning mechanism includes a plug interface 4 disposed on the end face of the interface seat 2. The plug interface 4 is provided with an elastic stylus assembly 5 and a stylus hole 6 correspondingly opened on the end face of the probe connection part 1. The elastic stylus assembly 5 consists of multiple beryllium copper stylus evenly distributed along the circumference in the plug interface 4, and the height of the elastic stylus assembly 5 is less than the height of the plug interface 4. One end of the elastic stylus assembly 5 is electrically connected to the signal line of the ultrasonic testing equipment, and the other end passes through the stylus hole 6 of the probe connection part 1 and is plugged in.
[0034] In this utility model, a guide pin 9 is provided on one side of the insertion interface 4 to restrict the insertion direction. The probe connection part 1 is provided with a corresponding guide groove 10 at the guide pin 9. The guide pin 9 and the guide groove 10 are fitted with a clearance. The top of the guide pin 9 is provided with a bevel for easy guidance.
[0035] In this utility model, the quick-lock mechanism includes an elastic buckle 7 disposed on one side of the interface seat 2, and a corresponding slot 8 opened on the probe connection part 1. The elastic buckle 7 achieves engagement or disengagement with the slot 8 through elastic deformation.
[0036] As per the instruction manual Figure 3As shown, the elastic buckle 7 includes an integrally formed pressing part 11, a connecting arm 12, and a locking part 13. The pressing part 11 is exposed on the side of the interface seat 2, and the inner side of the pressing part 11 is rotatably connected to the interface seat 2. The inner side of the connecting arm 12 is provided with a V-shaped spring sheet 14. The end of the locking part 13 is provided with a barb 15, which is interference-fitted with the groove of the slot 8. The interior of the interface seat 2 is provided with a corresponding movable cavity at the elastic buckle 7. When in use, by pressing down the pressing part 11, the connecting arm 12 and the locking part 13 are rotated inward and stored, thereby separating the barb 15 from the slot 8. The probe connecting part 1 is provided with a reinforcing cylinder 16 that wraps around the front end of the interface seat 2, and the slot 8 is opened on the reinforcing cylinder 16.
[0037] As per the instruction manual Figure 4 As shown, both the probe connector 1 and the interface base 2 have a sealing groove 17 on their connecting end faces. An O-ring 18 is embedded in the sealing groove 17. The O-ring 18 is made of fluororubber or silicone rubber.
[0038] Working principle
[0039] 1. Guiding and alignment: Align the guide groove 10 of the probe connector 1 with the guide pin 9 of the interface seat 2 and push it in axially. The lateral displacement is limited by the gap fit between the guide pin 9 and the guide groove 10 to ensure that the stylus and the stylus hole 6 are coaxial.
[0040] 2. Contact of the stylus: When the probe connection part 1 is pushed to the limit position, the beryllium copper stylus of the elastic stylus assembly 5 undergoes a slight deformation due to its own elasticity (deformation ≤ 0.5 mm), inserts into the stylus hole 6 and contacts the signal line inside the probe to achieve electrical conduction.
[0041] 3. Locking and fixing: Continue to push the probe connecting part 1 until the groove of the card slot 8 contacts the barb 15 of the elastic buckle 7; under the squeezing action of the barb 15, the connecting arm 12 of the elastic buckle 7 drives the pressing part 11 to close inward (the V-shaped spring plate 14 is compressed and stores energy). When the barb 15 is fully inserted into the card slot 8, the V-shaped spring plate 14 returns to its original position and pushes the connecting arm 12 to move outward. The barb 15 and the groove of the card slot 8 are interference-fitted to lock the interface seat 2.
[0042] 4. Unlocking operation: Press the pressing part 11 on the side of the interface seat 2 with your hand. The pressing part 11 rotates downward around the rotating axis, causing the connecting arm 12 and the locking part 13 to rotate inward and be stored (the V-shaped spring sheet 14 is compressed) until the barb 15 disengages from the slot 8.
[0043] 5. Pull out the probe: Slowly pull out the probe connector 1 along the axis, the guide pin 9 separates from the guide groove 10, the elastic stylus assembly 5 separates from the stylus hole 6, and the interface separation is completed.
[0044] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
