A support device for an ultrasonic probe

Abstract

This invention provides a support device for an ultrasonic probe, applicable to the installation of ultrasonic probes. The device includes a housing with a coiled iron inside. A fixing device is installed at the end of the coiled iron, and the probe is inserted into the fixing device. A positioning device is installed on the inner wall of the fixing device. A rectangular groove is formed at the top of the housing, and a limiting device is installed on the side of the housing near the rectangular groove. By inserting the probe into the fixing device inside the housing and then pulling out the end of the coiled iron, the coiled iron is fixed in a suitable position. During the pulling out process, the coiled iron tightens along the fixing device, compressing the auxiliary protrusions on the surface of the moving teeth. The moving teeth compress the probe inside the mounting sleeve during movement, ensuring the probe is securely installed within the mounting sleeve. After the coiled iron is stretched to a suitable length, it is fixed by the limiting device to prevent the coiled iron from retracting, allowing the ultrasonic probe to perform detection within a radius of the coiled iron, centered on its fixed position.

Description

Technical Field

[0001] This invention relates to the field of ultrasonic probe application and installation, and more particularly to a support device for an ultrasonic probe. Background Technology

[0002] An ultrasonic probe is a device that emits and receives ultrasonic waves during ultrasonic testing. The performance of the probe directly affects the characteristics of the ultrasonic waves and the detection performance. Because it needs to maintain close contact with the object being tested for a long time in order to obtain better detection results, a support device is usually used to fix the ultrasonic probe during use.

[0003] In general, the ultrasonic probe is first installed on one end of the support device, and then the other end is fixed in a suitable position. The ultrasonic probe is supported in the appropriate position by the support device and then the required detection position is detected. However, when performing tasks such as wall detection or large-area detection, the ultrasonic probe needs to detect multiple detection positions. When using the existing support device to support the ultrasonic probe, the ultrasonic probe is fixed in one detection position. When it is necessary to change the detection position, it is necessary to go beyond the support device to change the position and reinstall it and continue the detection. This will leave multiple installation points on the surface of the wall and the object to be detected. Repeated disassembly and reassembly will prolong the working time, reduce the work efficiency, and affect the progress of subsequent work. Summary of the Invention

[0004] The purpose of this invention is to provide a support device for an ultrasonic probe. In general, during use, the ultrasonic probe is first installed at one end of the support device, and then the other end is fixed in a suitable position. The ultrasonic probe is supported by the support device and can then be used to detect the desired location. However, for tasks such as wall inspection or large-area inspection, the ultrasonic probe needs to detect multiple locations. Using existing support devices, the ultrasonic probe is fixed at one detection position. When the detection position needs to be changed, it must be moved beyond the support device and reinstalled to continue testing. This leaves multiple installation points on the surface of the wall or the object to be inspected, and the repeated disassembly and reassembly prolongs working time, reduces work efficiency, and affects the progress of subsequent work. This addresses a technical problem.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: including a shell, wherein a coiled iron is disposed inside the shell, a fixing device is installed at the end of the coiled iron, a probe is inserted into the fixing device, and a positioning device is installed on the inner wall of the fixing device;

[0011] Preferably, the mounting sleeve consists of a base plate and a sleeve. A through groove is provided on the surface of the sleeve, and the through groove is S-shaped. The S-shaped through groove divides the surface of the sleeve of the mounting sleeve into four intersecting moving teeth. The end surface of the moving teeth is provided with auxiliary protrusions. The sleeve is a cylindrical tubular structure with an opening at one end and a closed end. The closed end of the sleeve has an opening adapted to the probe. The base plate is installed on the side of the sleeve away from the opening adapted to the probe.

[0012] Preferably, the mounting groove is divided into a rectangular part and a cylindrical part. The extrusion plate is set inside the rectangular part, and the connecting rod set at the top of the extrusion plate passes through the rectangular part and enters the cylindrical part to connect with the push rod. A retaining ring is set on the inner wall of the cylindrical part, and a spring is set at the bottom of the retaining ring. The other end of the spring is connected to the push rod.

[0013] The connecting rod passes through the rectangular part and enters the cylindrical part. The inner diameter of the groove where the rectangular part and the cylindrical part connect is larger than the diameter of the connecting rod, and the top of the groove inner wall is provided with a rounded chamfer.

[0018] Preferably, the inner wall of the mounting sleeve is provided with a groove that matches the raised texture on the probe surface, and the probe output end extends through the opening at one end of the mounting sleeve and the housing to the outside of the housing.

[0019] Preferably, the base plate of the mounting sleeve is provided with a rubber ring, and the length of the rubber ring protruding from the base plate is greater than the length of the probe protruding from the base plate.

[0020] The beneficial effects of this invention are:

[0021] This invention involves inserting the probe into a fixing device inside the housing, then pulling out the end of the coiled iron. After the coiled iron is pulled out, it is fixed in a suitable position. During the pulling out process, the coiled iron tightens along the fixing device, and during the tightening process, it squeezes the auxiliary protrusions on the surface of the moving teeth, causing the moving teeth to shift into the mounting sleeve. During the movement, the moving teeth squeeze the probe inside the mounting sleeve, ensuring that the probe is securely installed inside the mounting sleeve. When the probe is inserted into the mounting sleeve, the positioning device ensures that the probe is located in the center position of the mounting sleeve and pre-fixes the probe to prevent it from falling off. After the coiled iron is stretched to a suitable length, it is fixed by a limiting device to prevent the coiled iron from retracting. This allows the ultrasonic probe to perform detection within a range centered on the fixed position of the coiled iron and with the coiled iron as the radius. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0030] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0031] Example 1

[0032] In this embodiment, a support device for an ultrasonic probe is proposed, which includes a housing 1 and a coiled iron 2 installed inside the housing 1. A fixing device 3 is installed at the end of the coiled iron 2, a probe 4 is inserted into the fixing device 3, and a positioning device 5 is installed on the inner wall of the fixing device 3.

[0033] The fixing device 3 includes a mounting sleeve 301 and a through groove 302 formed on the surface of the mounting sleeve 301. The inner wall of the mounting sleeve 301 is provided with a groove that matches the raised texture on the surface of the probe 4. The output end of the probe 4 extends to the outside of the housing 1 through the opening at one end of the mounting sleeve 301 and the housing 1. The mounting sleeve 301 is divided into a base plate and a sleeve. The through groove 302 is provided on the surface of the sleeve and is S-shaped. The S-shaped through groove 302 divides the surface of the sleeve of the mounting sleeve 301 into four intersecting moving teeth 303. The end surface of the moving teeth 303 is provided with an auxiliary protrusion 304. The sleeve is a cylindrical tubular structure with an opening at one end and a closed end. The closed end of the sleeve has an opening that matches the probe 4. The base plate is installed on the side of the sleeve away from the opening that matches the probe 4.

[0034] The portion of the coil 2 extending to the outside of the housing 1 is provided with a mounting plate. The mounting plate is perpendicular to the coil 2 and is located on one side of the coil 2.

[0035] The mounting sleeve 301 has a rubber ring on its base plate surface, and the length of the rubber ring protruding from the base plate is greater than the length of the probe 4 protruding from the base plate.

[0036] The positioning device 5 includes a mounting groove 501 formed in the inner wall of the mounting sleeve 301. A pressing plate 502 is provided inside the mounting groove 501, and a connecting rod 503 is mounted on the top of the pressing plate 502 via a hinge. A push rod 504 is mounted on the other end of the connecting rod 503 via a hinge. The mounting groove 501 is divided into a rectangular part and a cylindrical part. The pressing plate 502 is set inside the rectangular part, and the connecting rod 503 set on the top of the pressing plate 502 passes through the rectangular part and enters the cylindrical part to connect with the push rod 504. A retaining ring 505 is provided on the inner wall of the cylindrical part, and a spring 506 is provided at the bottom of the retaining ring 505. The other end of the spring 506 is connected to the push rod 504.

[0037] Where the connecting rod 503 passes through the rectangular part and enters the cylindrical part, the inner diameter of the groove at the connection between the rectangular part and the cylindrical part is larger than the diameter of the connecting rod 503, and the top of the inner wall of the groove is provided with a rounded chamfer.

[0038] For details, please refer to Figure 1-4 This embodiment proposes an ultrasonic probe support device, which combines a housing 1, a coiled iron 2, a fixing device 3, a probe 4, and a positioning device 5. The device aims to place the probe 4 within the inner cavity of the mounting sleeve 301. When the probe 4 is inserted into the mounting sleeve 301, the shape of the probe 4 surface itself pushes the push rod 504 upward. As the push rod 504 moves upward, it rotates along the mounting groove 501, thereby driving the extrusion plate 502 to move towards the center of the mounting sleeve 301. During the movement, the extrusion plate 502 contacts the probe 4, so that the probe 4 is pre-fixed inside the mounting sleeve 301.

[0039] Next, pull out the end of the coil 2. After the coil 2 is pulled out, fix it in a suitable position. During the process of pulling out the coil 2, it tightens along the mounting sleeve 301. During the tightening process, the auxiliary protrusion 304 on the surface of the moving tooth 303 on the surface of the mounting sleeve 301 is squeezed, causing the moving tooth 303 to shift into the mounting sleeve 301. During the movement, the moving tooth 303 squeezes the probe 4 inside the mounting sleeve 301 to ensure that the probe 4 is installed firmly inside the mounting sleeve 301.

[0040] Example 2

[0041] In this embodiment, a support device for an ultrasonic probe is proposed, which includes a housing 1 and a coiled iron 2 installed inside the housing 1. A fixing device 3 is installed at the end of the coiled iron 2, a probe 4 is inserted into the fixing device 3, and a positioning device 5 is installed on the inner wall of the fixing device 3.

[0042] The top of the housing 1 is provided with a rectangular groove 6, and an annular cavity is left between the housing 1 and the fixing device 3. The coiled iron 2 is set inside the annular cavity and extends through the rectangular groove 6 to the outside of the housing 1. A limiting device 7 is installed on the side of the housing 1 near the rectangular groove 6.

[0043] The rubber strip 701 is made of a high-friction flexible material and is installed on one side of the rectangular groove 6. The movable plate 702 on the other side of the rectangular groove 6 is connected to the housing 1 by a hinge. The movable plate 702 is L-shaped and extends into the interior of the rectangular groove 6.

[0044] The movable plate 702 located inside the rectangular groove 6 has a protrusion made of the same material as the adhesive strip 701 on one side and a fixed protrusion on the other side. The inner wall of the rectangular groove 6 has a groove that matches the fixed protrusion.

[0045] For details, please refer to Figure 1-6 This embodiment proposes a support device for an ultrasonic probe. This support device combines a housing 1, a coil 2, a fixing device 3, a probe 4, a positioning device 5, a rectangular groove 6, and a limiting device 7. After performing the steps of Embodiment 1, the rectangular groove 6 allows the end of the coil 2 to extend to the outside of the housing 1. When the coil 2 is stretched outward, it also activates the movable plate 702, allowing the end of the movable plate 702 to enter the interior of the rectangular groove 6. The protrusions on the surface of the movable plate 702 contact the coil 2 and deform during the process of pushing the coil 2 towards the adhesive strip 701. The deformation continues until the fixing protrusion on the other side of the movable plate 702 and the groove on the inner wall of the rectangular groove 6, which is adapted to the fixing protrusion, engage with each other and stop. At this time, the adhesive strip 701 and the protrusions on the surface of the movable plate 702 clamp the coil 2, ensuring that the coil 2 will not continue to move outward or rewind and reset.

[0046] Working principle description: First, when using the device, insert the probe 4 into the mounting sleeve 301. When the probe 4 is inserted into the mounting sleeve 301, the shape of the probe surface itself pushes the push rod 504 upward. When the push rod 504 moves upward, it rotates along the mounting groove 501, thereby driving the extrusion plate 502 to move towards the center of the mounting sleeve 301. During the movement, the extrusion plate 502 contacts the probe 4, so that the probe 4 is pre-fixed inside the mounting sleeve 301. Then, pull out the end of the coil 2. After the coil 2 is pulled out, it is fixed in a suitable position. During the pulling out process, the coil 2 tightens along the mounting sleeve 301. During the tightening process, it squeezes the auxiliary protrusion 304 on the surface of the moving teeth 303 on the surface of the mounting sleeve 301, causing the moving teeth 303 to shift into the mounting sleeve 301. During the movement, the moving teeth 303 squeeze the probe 4 inside the mounting sleeve 301, ensuring that the probe 4 is installed firmly inside the mounting sleeve 301.

[0047] When the end of the coil 2 is pulled out, it extends along the rectangular groove 6 to the outside of the housing 1. When the coil 2 is stretched outward, the movable plate 702 is also moved, so that the end of the movable plate 702 enters the interior of the rectangular groove 6. The protrusion on the surface of the movable plate 702 contacts the coil 2 and deforms during the process of pushing the coil 2 towards the rubber strip 701. It stops when the fixed protrusion on the other side of the movable plate 702 and the groove on the inner wall of the rectangular groove 6 that matches the fixed protrusion are engaged with each other. At this time, the rubber strip 701 and the protrusion on the surface of the movable plate 702 clamp the coil 2, ensuring that the coil 2 will not continue to move outward or rewind and reset.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
