Description

Technical Field

[0001] This utility model relates to the field of detection tools, specifically a handheld drone detection tool. Background Technology

[0002] In the field of detection tool technology, handheld or drone-mounted ultrasonic detection equipment often faces the challenge of balancing operational flexibility and structural stability. Traditional tools typically have fixed or single-degree-of-freedom adjustable detection angles, making them unsuitable for detecting complex equipment surfaces or confined spaces. Operators must frequently move their hands or adjust the drone's attitude, leading to reduced detection efficiency. Furthermore, the signal transmission cables of existing tools are often directly run inside the housing without specific buffering and protective structures, making them prone to poor contact or cable wear under bending or vibration conditions, affecting signal transmission stability. In addition, the grip design of some tools does not adequately consider ergonomics, leading to hand fatigue after prolonged use. Drone-mounted devices lack a balance between lightweight structure and vibration resistance, making them susceptible to airflow disturbances that can affect detection accuracy. Regarding environmental adaptability, traditional tools have relatively simple sealing and dustproof designs, making internal components susceptible to corrosion in humid and dusty outdoor environments, shortening the equipment's lifespan. These issues collectively restrict the reliability and ease of operation of ultrasonic detection tools in complex scenarios. Utility Model Content

[0017] In this embodiment, the probe fixing ring 1 is the lower base support component, and a fixing base plate 12 is horizontally arranged inside it. The fixing base plate 12 is fixedly connected to the inner wall of the probe fixing ring 1 by bolts to form a stable structure of the detection end.

[0018] like Figure 1 and Figure 3 As shown, in this embodiment, a circular detection groove 13 is provided on the upper part of the fixed base plate 12, and an ultrasonic detection head 11 is provided directly above the detection groove 13. The ultrasonic detection head 11 is embedded in the inner side of the tool protective housing 2, and its lower end is aligned with the detection groove 13 and fixed to the fixed base plate 12 by bolts to ensure accurate alignment between the detection head and the area to be detected.

[0019] In this embodiment, the upper end of the tool protective housing 2 is fixedly connected to the connecting pipe 3. A sleeve 9 is fitted inside the upper part of the connecting pipe 3. The sleeve 9 is a rubber component and is fixed to the inner wall of the connecting pipe 3 by interference fit. The inner side of the sleeve wraps the connecting wire 7, which can buffer the stress of the connecting wire 7 when bending and avoid wire wear.

[0020] like Figure 2 As shown, in this embodiment, the upper end of the ultrasonic probe 11 is integrally formed with a wire fixing sleeve 10, and the lower end of the connecting wire 7 is fixed to the signal interface of the ultrasonic probe 11 through the wire fixing sleeve 10 to prevent signal interruption due to loose connection.

[0021] like Figure 1 As shown, in this embodiment, the upper end of the connecting pipe 3 is connected to the multi-segment rigid universal joint mechanism 4 through the adjuster 14. The adjuster 14 is a threaded connector with locking function, which can adjust the initial angle of the universal joint mechanism by rotation. The upper end of the multi-segment rigid universal joint mechanism 4 is connected to the protective pipe housing 5 through another adjuster 14, forming a middle section structure that can be bent at multiple angles to adapt to the angle requirements of different detection scenarios.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, the upper end of the protective tube housing 5 is welded and fixed to the fixing ring 6. A spring-type sensor 8 is vertically welded to the upper part of the fixing ring 6. The central axis of the spring-type sensor 8 coincides with the fixing ring 6. A through hole is opened inside the spring-type sensor 8. The connecting line 7 passes through the through hole and extends to the upper part of the spring-type sensor 8. The inner wall of the through hole and the connecting line 7 are fixed with sealant to achieve waterproof and dustproof protection.

[0023] like Figure 2 As shown, in this embodiment, the connecting wire 7 passes through the interior of the ultrasonic probe 11, the wire fixing sleeve 10, the sleeve 9 of the connecting tube 3, the hollow channel of the multi-segment rigid universal joint mechanism 4, the protective tube housing 5 and the fixing ring 6 in sequence, and finally extends to the outside through the through hole of the spring-type induction 8, forming a complete signal transmission path.

[0024] like Figure 4 As shown, in this embodiment, the multi-segment rigid universal joint mechanism 4 is composed of multiple metal universal joint units connected in series. Each unit is connected by a damping shaft, which can be bent arbitrarily within a multi-angle range and maintain a fixed angle, making it convenient for operators to adjust the detection direction without moving their hands.

[0025] like Figures 1-3 As shown, in this embodiment, the tool protective housing 2, the connecting tube 3, and the protective tube housing 5 are all made of engineering plastic, which combines lightweight and structural strength, and are suitable for handheld or drone mounting.

[0026] In this embodiment, the outer wall of the fixing ring 6 is provided with anti-slip texture, which conforms to the ergonomic design and makes it easy for operators to hold or quickly dock with the drone mounting device.

[0027] like Figure 2 and Figure 4As shown, in this embodiment, both the sleeve 9 and the wire fixing sleeve 10 are made of high and low temperature resistant rubber material, which is suitable for complex outdoor working conditions.

[0028] like Figure 5 As shown, in this embodiment, annular damping pads are provided between the metal universal joint units of the multi-segment rigid universal joint mechanism 4. The damping pads are made of nitrile rubber and are fitted to the end face of the universal joint unit through embedded installation. When the universal joint mechanism is bent, the damping pads can provide uniform friction force to ensure that there is no loosening after the bending angle is locked, while reducing direct wear between metal parts.

[0029] like Figure 6 As shown in this embodiment, the outer wall of the adjuster 14 has two strip-shaped anti-slip protrusions symmetrically distributed. The height of the protrusions is adapted to the diameter of the adjuster body.

[0031] In this embodiment, three reinforcing ribs are evenly distributed along the axial direction on the inner wall of the protective tube shell 5. The reinforcing ribs are integrally formed with the protective tube shell 5 and have a triangular cross-section. The reinforcing ribs can enhance the bending strength of the protective tube shell 5 and prevent the shell from deforming due to airflow vibration when the UAV is mounted.

[0032] like Figure 5 and Figure 7 As shown, in this embodiment, annular sealing rings are provided at both ends of the multi-segment rigid universal joint mechanism 4. The sealing rings are made of fluororubber and are installed by groove embedding. When the universal joint mechanism is threadedly connected to the adjuster 14, the sealing rings are compressed to form a sealing cavity to prevent rainwater or moisture from seeping into the interior and corroding the connecting line 7.
