Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology for metal surfaces, and specifically to a probe anti-scratch protection device for non-destructive testing of metal surfaces. Background Technology

[0002] Non-destructive testing (NDT) technology plays a crucial role in the production and quality inspection of metal materials and products. As a key component of testing equipment, NDT probes directly contact the metal surface to obtain test data. However, in actual testing work, probes face many risks of being scratched.

[0003] Existing protection methods are relatively simple, such as simply using a regular rubber sleeve to wrap the probe. However, the wear resistance and fit of the rubber sleeve are limited. Under conditions of frequent probe movement and uneven force, it is difficult to continuously and effectively protect the probe and cannot fully play its protective role. Therefore, there is an urgent need for a probe anti-scratch protection device for non-destructive testing of metal surfaces to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to provide a scratch-resistant protection device for probes used in non-destructive testing of metal surfaces, which has the advantage of good protection effect, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant protection device for a probe used in non-destructive testing of metal surfaces, comprising a protective component and a detection probe, wherein the detection probe is disposed within the inner cavity of the protective component, and the protective component comprises a protective cover, a cross-shaped protective fixing cover, a first sliding groove, a first spring, a limiting plate, a first slider, a through groove, a sliding sleeve, a limiting sliding rod bracket, a second spring, an annular seat, a universal wheel, a positioning groove, a fixing rod, a positioning sliding rod, a third spring, and a second sliding groove.

[0006] Furthermore, a through groove is provided at the bottom of the inner cavity of the protective cover, and sliding sleeves are fixedly installed around the bottom of the protective cover. The inner cavity of the sliding sleeves is slidably connected to a limit sliding rod frame.

[0007] Furthermore, an annular seat is fixedly installed at the bottom of the limiting slide bar frame, and evenly distributed casters are fixedly installed at the bottom of the annular seat. A second spring is sleeved on the surface of the limiting slide bar frame.

[0008] Furthermore, positioning grooves are provided on both sides of the top of the protective cover, a third spring is fixedly installed in the inner cavity of the positioning groove, and a fixing rod is fixedly installed on the top of the third spring.

[0009] Furthermore, a second sliding groove is provided inside the fixing rod, and a positioning sliding rod is slidably connected inside the second sliding groove. The two sides of the positioning sliding rod are fixedly connected to the inner cavity of the positioning groove.

[0010] Furthermore, a cross-shaped protective cover is fixedly installed on the top of the fixed rod, and a first sliding groove is provided around the top of the cross-shaped protective cover. A first slider is slidably connected inside the first sliding groove.

[0011] Furthermore, a limiting plate is fixedly installed on the top of the first slider, and a first spring is fixedly installed in the inner cavity of the first groove on the side relatively far away from the first slider.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention protects the detection probe by setting up a protective component. During installation, first, the protective cover is placed on the surface of the detection probe. Then, the cross-shaped protective fixing cover is pulled upward. Under the action of force, the cross-shaped protective fixing cover moves the fixing rod upward, thereby deforming the third spring. Then, the limiting plate is released. Under the action of the first spring, the first slider moves the limiting plate inward, thereby limiting the top of the detection probe. Then, under the action of the third spring, the limiting plate is pressed tightly against the top of the detection probe. In use, simply press the protective cover, which moves the limiting slide rod and caster downward through the protective cover, leaving a gap with the metal surface. It has the advantage of good protection effect and solves the problem that some existing protection methods are relatively simple, such as simply using a common rubber sleeve to wrap the probe. However, the wear resistance and fit of the rubber sleeve are limited, and it is difficult to continuously and effectively protect the probe under frequent movement and uneven force, thus failing to give full play to the protective function.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figure 1-4 As shown, a scratch-resistant protection device for a probe used in non-destructive testing of metal surfaces includes a protection component 1 and a detection probe 2. The detection probe 2 is disposed in the inner cavity of the protection component 1. The protection component 1 includes a protective cover 11, a cross-shaped protective fixing cover 12, a first sliding groove 13, a first spring 14, a limiting plate 15, a first slider 16, a through groove 17, a sliding sleeve 18, a limiting sliding rod bracket 19, a second spring 191, an annular seat 192, a universal wheel 193, a positioning groove 194, a fixing rod 195, a positioning sliding rod 196, a third spring 197, and a second sliding groove 198.

[0021] More specifically, the detection probe 2 is protected by a protective component 1. During installation, the protective cover 11 is first placed on the surface of the detection probe 2. Then, the cross-shaped protective fixing cover 12 is pulled upward. Under the action of force, the cross-shaped protective fixing cover 12 moves the fixing rod 195 upward, thereby deforming the third spring 197. Then, the limiting plate 15 is released. Under the action of the first spring 14, the first slider 16 moves the limiting plate 15 inward, thereby limiting the top of the detection probe 2. Then, under the action of the third spring 197, the limiting plate 15 is tightly attached to the top of the detection probe 2. In use, simply press the protective cover 11, which moves the limiting slide rod 19 and the universal wheel 193 downward, leaving a gap with the metal surface. This has the advantage of good protection effect and solves the problem that some existing protection methods are relatively simple, such as simply using a common rubber sleeve to wrap the probe. However, the wear resistance and fit of the rubber sleeve are limited, and it is difficult to continuously and effectively protect the probe under frequent movement and uneven force, thus failing to fully exert the protective function.

[0022] In some embodiments, a through groove 17 is provided at the bottom of the inner cavity of the protective cover 11, and a sliding sleeve 18 is fixedly installed around the bottom of the protective cover 11. The inner cavity of the sliding sleeve 18 is slidably connected to a limiting slide rod frame 19. More specifically, the through groove 17 facilitates the detection probe 2 to detect the metal surface, and the sliding sleeve 18 limits the limiting slide rod frame 19 to prevent the limiting slide rod frame 19 from shaking during movement.

[0023] In some embodiments, an annular seat 192 is fixedly installed at the bottom of the limiting slide bar 19, and a uniformly distributed caster wheel 193 is fixedly installed at the bottom of the annular seat 192. A second spring 191 is sleeved on the surface of the limiting slide bar 19. More specifically, the limiting slide bar 19 is used to limit the protective cover 11, and the caster wheel 193 is used to facilitate the movement of the entire device on the metal surface.

[0024] In some embodiments, positioning grooves 194 are provided on both sides of the top of the protective cover 11. A third spring 197 is fixedly installed in the inner cavity of the positioning groove 194, and a fixing rod 195 is fixedly installed on the top of the third spring 197. More specifically, the third spring 197 is installed by setting the positioning groove 194, and the fixing rod 195 is reset by setting the third spring 197.

[0025] In some embodiments, a second sliding groove 198 is provided inside the fixed rod 195, and a positioning sliding rod 196 is slidably connected inside the second sliding groove 198. The two sides of the positioning sliding rod 196 are fixedly connected to the inner cavity of the positioning groove 194. More specifically, the positioning sliding rod 196 is limited by the second sliding groove 198, and the fixed rod 195 is limited by the positioning sliding rod 196 to prevent the fixed rod 195 from shaking during movement.

[0026] In some embodiments, a cross-shaped protective cover 12 is fixedly installed on the top of the fixing rod 195. A first sliding groove 13 is provided around the top of the cross-shaped protective cover 12. A first slider 16 is slidably connected inside the first sliding groove 13. More specifically, the cross-shaped protective cover 12 is limited by the fixing rod 195 to prevent the cross-shaped protective cover 12 from shaking during movement.

[0027] In some embodiments, a limiting plate 15 is fixedly installed on the top of the first slider 16, and a first spring 14 is fixedly installed in the inner cavity of the first groove 13 on the side relatively far away from the first slider 16. More specifically, the first slider 16 is limited by the first groove 13 to prevent the first slider 16 from shaking during movement, and the limiting plate 15 is limited by the first slider 16 to prevent the limiting plate 15 from shaking during movement.

[0028] Working principle:

[0029] Step 1: During installation, first, put the protective cover 11 on the surface of the detection probe 2, then pull the cross protective fixing cover 12 upward. Under the action of force, the cross protective fixing cover 12 drives the fixing rod 195 to move upward, thereby deforming the third spring 197. Then, release the limiting plate 15. Under the action of the first spring 14, the first slider 16 drives the limiting plate 15 to move inward, thereby limiting the top of the detection probe 2.

[0030] Step 2: Next, under the action of the third spring 197, the limiting plate 15 is pressed tightly against the top of the detection probe 2. When in use, simply press the protective cover 11, and the limiting slide bar 19 and the universal wheel 193 will move downward through the protective cover 11, and there will be a gap with the metal surface, which has the advantage of good protection effect.
