Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, specifically a protective structure for a steel structure ultrasonic detector. Background Technology

[0002] Steel plates are generally used to construct railway or highway bridges, requiring high strength, toughness, and the ability to withstand the loads and impacts of locomotives and rolling stock. They also need to have good fatigue resistance, certain low-temperature toughness, and resistance to atmospheric corrosion. Furthermore, the surface quality of the steel is required to be high. Therefore, an ultrasonic testing device for bridge steel structure inspection mainly uses ultrasonic waves to inspect the bridge steel structure, thereby determining whether the steel structure has aged or is abnormal through the returned ultrasonic waves.

[0003] Chinese Utility Model Patent Publication No. CN219533022U discloses an ultrasonic testing device for steel structure inspection. This device comprises a testing instrument, a neck strap, a testing rod, a storage box, a sliding groove, and a dust cover. During use, the operator can hang the neck strap around their neck while inspecting steel plates, allowing the testing rod to be stored in the storage box. The dust cover is then secured to the testing rod along the sliding groove, enabling storage when the operator is not using the instrument. The neck strap facilitates carrying the testing instrument. However, this ultrasonic testing device for steel structure inspection lacks a protective structure for the detector screen and probe connection port. This makes the detector susceptible to damage from the external environment during transport, affecting its normal operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a protective structure for a steel structure ultrasonic detector. It can effectively solve the problem that the existing technology does not have a screen protection structure for the detector, which makes the display screen and operation buttons of the detector body easily damaged by the external environment during the transport process, thus affecting normal use.

[0005] The technical solution adopted by this utility model is: a protective structure for a steel structure ultrasonic detector, including a detector body and a locking assembly. The detector body is provided with an indicator light, an operation button and a display screen. A protective cover is wrapped around the outer edge of the detector body. A connecting end is provided at one end of the detector body. A protective cover is fixedly installed at the end of the detector body near the connecting end. A groove is opened at the end of the protective cover away from the detector body. A rubber sleeve is provided at the end of the protective cover away from the detector body. A sliding cover limiting component is fixedly installed at the end of the protective cover away from the protective cover, and the detector body is slidably connected to the protective cover through the sliding cover limiting component; The locking assembly includes a sliding sleeve with a guide groove extending from top to bottom. A limit block is slidably connected in the guide groove, and the side of the limit block away from the protective cover is designed with an angle.

[0006] Preferably, the sliding cover limiting assembly includes a slide rail, with a positioning bolt threaded to the end of the slide rail away from the detector body, and a slide groove provided at the end of the slide rail near the protective cover, through which the protective cover is slidably connected.

[0007] Through the above technical solution, the design of the slide groove and the positioning bolt allows the slide rail to be installed on one end of the protective cover via the positioning bolt. Then, the protective cover slides above the detector body via the slide groove. When not in use, it can be closed to prevent damage to the display screen on the detector body during transport.

[0008] Preferably, the protective cover is made of iron, and a magnetic block is fixedly installed at one end of the protective cover near the protective cover. The magnetic block is magnetically connected to the protective cover.

[0009] With the above technical solution, when the protective cover is closed, the magnetic block and the iron protective cover form a magnetic connection, which can automatically attract and keep it closed. This can prevent the protective cover from being accidentally opened due to shaking during carrying, and effectively protect the display screen and operation buttons of the detector body from damage by the external environment.

[0010] Preferably, a spring is provided at one end of the limiting block, the other end of the spring away from the limiting block is connected to the sliding sleeve, and a pull rod is fixedly installed at the other end of the limiting block away from the detector body.

[0011] Through the above technical solution, the elastic reset effect of the spring can keep the limit block in the locked state at all times. When the pull rod is pulled, the spring can be compressed to drive the limit block out of the locked position, which makes it easy to open the protective cover quickly. The angled design of the limit block allows it to slide into the guide groove automatically when the protective cover is closed, and locking can be completed without additional operation. This improves the convenience of use and ensures that the protective cover will not unlock itself in a vibration environment.

[0012] Preferably, the outer edge of the connecting end is provided with an external thread, and a detection probe is provided at the end of the connecting end away from the detector body. The detection probe passes through the protective cover and is connected to the detection probe.

[0013] Through the above technical solution, the external thread design of the connecting end can realize the quick disassembly and assembly of the detection probe, making it easy to replace the adapter probe according to different detection needs. The protective cover can provide physical protection for the detection probe and prevent the probe from being damaged by collision when it comes into contact with the steel structure surface.

[0014] Preferably, a shoulder strap assembly is fixedly installed at one end of the protective cover away from the protective cover. The shoulder strap assembly includes a mounting base, and a connecting frame is fixedly installed at the other end of the mounting base away from the detector body. A connecting strap is provided at the other end of the connecting frame away from the mounting base.

[0015] Through the above technical solution, the mounting base and connecting frame of the shoulder strap assembly provide a stable mounting point for the shoulder strap. The connecting strap can attach the detector body to the operator's body, which can effectively reduce the burden of hand-held operation in high-altitude steel structure inspection or long-distance movement scenarios.

[0016] Preferably, there are two identical connecting frames and mounting bases, and the connecting strip connects the two connecting frames and mounting bases. The outer surface of the connecting strip is provided with anti-slip texture.

[0017] Through the above technical solution, the two symmetrically arranged connecting frames and mounting bases can make the strap assembly bear force evenly, preventing the detector body from tilting when carried. The anti-slip texture on the outer surface of the connecting strap can increase the friction with clothing and prevent the strap from slipping during movement.

[0018] Compared with the prior art, this utility model provides a protective structure for a steel structure ultrasonic detector, which has the following beneficial effects: 1. The protective structure of this steel structure ultrasonic detector uses a sliding groove and positioning bolt design. The sliding rail can be installed to one end of the protective cover through the positioning bolt, and then the protective cover can slide above the detector body through the sliding groove. When not in use, it can be closed to avoid damage to the display screen on the detector body during carrying. The elastic return action of the spring can keep the limit block in the locked state. When the pull rod is pulled, the spring can be compressed to drive the limit block out of the locked position, which facilitates quick opening of the protective cover. The angled design of the limit block allows it to automatically slide into the guide groove when the protective cover is closed, and locking can be completed without additional operation. This improves the convenience of use and ensures that the protective cover will not unlock itself in the vibration environment. 2. The steel structure ultrasonic detector uses a protective structure. The mounting base and connecting frame of the shoulder strap assembly provide a stable mounting point for the shoulder strap. The connecting strap allows the detector body to be attached to the operator's body. In high-altitude inspection of steel structures or long-distance movement scenarios, it can effectively reduce the burden on the hand. The external thread design of the connecting end can realize the quick disassembly and assembly of the detection probe, which is convenient for changing the adapter probe according to different detection needs. The protective cover can provide physical protection for the detection probe and prevent the probe from being damaged by collision when it comes into contact with the surface of the steel structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-8 As shown, the present invention provides a protective structure for a steel structure ultrasonic detector, including a detector body 1 and a locking assembly 14. The detector body 1 is provided with an indicator light 2, an operation button 3 and a display screen 4. A protective cover 16 is wrapped around the outer edge of the detector body 1. A connecting end 5 is provided at one end of the detector body 1. A protective cover 8 is fixedly installed at the end of the detector body 1 near the connecting end 5. A groove 9 is provided at the end of the protective cover 8 away from the detector body 1. A rubber sleeve 10 is provided at the end of the protective cover 8 away from the detector body 1. A sliding cover limiting component 11 is fixedly installed at the end of the protective cover 16 away from the protective cover 8, and the detector body 1 is slidably connected to the protective cover 15 through the sliding cover limiting component 11; The locking assembly 14 includes a sliding sleeve 1401, which has a guide groove 1402 extending from top to bottom. A limit block 1404 is slidably connected in the guide groove 1402, and the side of the limit block 1404 away from the protective cover 15 is designed with an angle.

[0023] Specifically, the sliding cover limiting assembly 11 includes a slide rail 1101. The end of the slide rail 1101 away from the detector body 1 is threaded with a positioning bolt 1102. The end of the slide rail 1101 near the protective cover 15 is provided with a slide groove 1103. The slide rail 1101 is slidably connected to the protective cover 15 through the slide groove 1103. The advantage is that, through the design of the slide groove 1103 and the positioning bolt 1102, the slide rail 1101 can be installed on one end of the protective cover 16 through the positioning bolt 1102. Then, the protective cover 15 slides above the detector body 1 through the slide groove 1103. When not in use, it can be closed to avoid damage to the display screen 4 on the detector body 1 during carrying.

[0024] Specifically, the protective cover 15 is made of iron. A magnetic block 12 is fixedly installed at one end of the protective cover 16 near the protective cover 8. The magnetic block 12 and the protective cover 15 are magnetically connected. The advantage is that when the protective cover 15 is closed, the magnetic block 12 and the iron protective cover 15 form a magnetic connection, which can automatically attract and keep it closed. This can prevent the protective cover 15 from being accidentally opened due to shaking during carrying, and effectively protect the display screen 4 and operation button 3 of the detector body 1 from damage by the external environment.

[0025] Specifically, a spring 1403 is provided at one end of the limiting block 1404, and the other end of the spring 1403 away from the limiting block 1404 is connected to the sliding sleeve 1401. A pull rod 1405 is fixedly installed at the other end of the limiting block 1404 away from the detector body 1. The advantage is that the elastic restoring effect of the spring 1403 can keep the limiting block 1404 in a locked state. When the pull rod 1405 is pulled, the spring 1403 can be compressed to drive the limiting block 1404 out of the locked position, which facilitates the quick opening of the protective cover 15. The angled design of the limiting block 1404 allows it to automatically slide into the guide groove 1402 when the protective cover 15 is closed, and locking can be completed without additional operation. This improves the convenience of use and ensures that the protective cover 15 will not unlock itself in a vibration environment.

[0026] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, an external thread 6 is provided on the outer edge of the connecting end 5, and a detection probe 7 is provided at the end of the connecting end 5 away from the detector body 1. The detection probe 7 passes through the protective cover 8 and is connected to the detection probe 7. The advantage is that the design of the external thread 6 of the connecting end 5 can realize the quick installation and removal of the detection probe 7, which is convenient for replacing the adapter probe according to different detection needs. The protective cover 8 can provide physical protection for the detection probe 7 and prevent the probe from being damaged by collision when it comes into contact with the steel structure surface.

[0028] Specifically, a shoulder strap assembly 13 is fixedly installed at one end of the protective cover 16 away from the protective cover 8. The shoulder strap assembly 13 includes a mounting base 1301. A connecting frame 1302 is fixedly installed at the other end of the mounting base 1301 away from the detector body 1. A connecting strap 1303 is provided at the other end of the connecting frame 1302 away from the mounting base 1301. The advantage is that the mounting base 1301 and the connecting frame 1302 of the shoulder strap assembly 13 provide a stable mounting support for the shoulder strap. The connecting strap 1303 can attach the detector body 1 to the operator's back, which can effectively reduce the burden of hand holding in high-altitude steel structure inspection or long-distance movement scenarios.

[0029] Specifically, there are two identical connecting frames 1302 and mounting bases 1301. A connecting strap 1303 connects the two connecting frames 1302 and mounting bases 1301. The outer surface of the connecting strap 1303 is provided with anti-slip textures 1304. The advantage is that the two symmetrically arranged connecting frames 1302 and mounting bases 1301 can make the strap assembly 13 evenly stressed, preventing the detector body 1 from tilting when carried. The anti-slip textures 1304 on the outer surface of the connecting strap 1303 can increase the friction with clothing and prevent the strap from slipping during movement.

[0030] Working principle: During use, the slide rail 1101 is installed on one end of the protective cover 16 via the positioning bolt 1102, thanks to the design of the slide groove 1103 and positioning bolt 1102. The protective cover 15 then slides above the detector body 1 via the slide groove 1103. When not in use, it can be closed to prevent damage to the display screen 4 on the detector body 1 during transport. When the protective cover 15 is closed, the magnetic block 12 forms a magnetic connection with the iron protective cover 15, automatically adsorbing and maintaining a closed state. This prevents the protective cover 15 from accidentally opening due to shaking during transport, effectively protecting the display screen 4 and operation buttons 3 of the detector body 1 from external environmental damage. The elastic return action of the spring 1403 keeps the limit block 1404 locked. Pulling the lever 1405 compresses the spring 1403, causing the limit block 1404 to disengage from the locked position, facilitating quick opening of the protective cover 15. The angled design of the limit block 1404 ensures that the protective cover 15 remains closed. The device can automatically slide into the guide groove 1402 and lock without additional operation, improving ease of use and ensuring that the protective cover 15 will not unlock on its own in a vibration environment. The external thread 6 design of the connecting end 5 allows for quick installation and removal of the detection probe 7, facilitating the replacement of the appropriate probe according to different detection needs. The protective cover 8 provides physical protection for the detection probe 7, preventing it from being damaged by impact when in contact with the steel structure surface. The mounting base 1301 and connecting frame 1302 of the shoulder strap assembly 13 provide a stable mounting point for the shoulder strap. The connecting strap 1303 allows the detector body 1 to be attached to the operator's body, effectively reducing the burden of holding the device in high-altitude steel structure inspection or long-distance movement scenarios. The two symmetrically arranged connecting frames 1302 and mounting base 1301 ensure that the shoulder strap assembly 13 is evenly stressed, preventing the detector body 1 from tilting when carried. The anti-slip texture 1304 on the outer surface of the connecting strap 1303 increases the friction with clothing, preventing the shoulder strap from slipping during movement.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
