Description

Technical Field

[0001] This utility model relates to the field of cable path detectors, specifically a universal testing frame for cable path detectors. Background Technology

[0002] Cable path detectors are common tools used to locate and trace the paths of underground cables and pipelines. They typically consist of a transmitter, a receiver, and a detection frame (or probe, sensor) connected to the receiver. During operation, the operator holds the detection frame and moves it close to the ground to detect the electromagnetic field signals generated by the underground cables.

[0003] In existing technologies, most detection frames are fixedly connected to the receiver host or handle or have limited hinged connections. This structure makes it difficult to keep the detection frame parallel to the ground or at the optimal detection angle when operating in complex terrain. This results in unstable signal reception, reduced detection accuracy, and the operator needs to constantly bend over or adjust their body posture to adapt to the terrain, increasing labor intensity and reducing detection efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a universal testing frame for a cable path detector. This universal testing frame for a cable path detector has a simple structure and is easy to operate. It can flexibly adjust the detection angle to adapt to the detection needs of complex terrain, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal testing frame for a cable path detector, comprising a ball cup base, a ball cup bolted to the lower end of the ball cup base, a ball head embedded in the ball cup, a connecting flange mounted on the protruding movable end of the ball head, and a path detector mounted on the connecting flange by bolts. A first connecting plate is mounted on the outer surface of the ball cup base, a second connecting plate abutting against the first connecting plate, an inclined plate mounted on one end of the second connecting plate, fixing blocks mounted on both sides of the upper end of the inclined plate, a damping rotating shaft mounted on one side of the fixing block, the two ends of the damping rotating shaft connected to the fixing blocks, a connecting sleeve mounted on the middle section of the damping rotating shaft, and a threaded hole provided on the connecting sleeve.

[0006] Furthermore, a threaded post is installed inside the threaded hole, and the threaded post is inserted into the threaded hole and connected to the hole wall by threads.

[0007] Furthermore, a hand handle is installed on one end of the threaded post, and the hand handle is integrally formed with the threaded post.

[0008] Furthermore, a handle is installed on the end of the hand-held rod away from the threaded post, and the handle is adhesively connected to the hand-held rod.

[0009] Furthermore, first connecting blocks are installed on both sides of the first connecting plate, and the first connecting blocks are integrally formed with the first connecting plate.

[0010] Furthermore, second connecting blocks are installed on both sides of the second connecting plate at corresponding positions to the first connecting block, and the first connecting block is connected to the second connecting block by bolts.

[0011] Furthermore, a handle bracket is installed on the outer surface of the ball bowl, and the handle bracket is integrally formed with the ball bowl.

[0012] Furthermore, a screwdriver is abutted against one end of the handle bracket, and the screwdriver passes through a through hole in the handle bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves multi-angle universal adjustment of the testing frame through three core mechanical components: ball head, ball cup seat, and locking sleeve. It has a compact structure and low manufacturing and maintenance costs. The ball head and ball cup seat cooperate to allow the ball cup base to pitch and rotate at large angles relative to the handle in any direction, easily handling various complex and uneven ground. This ensures that the path detector is always close to the area being tested at the optimal angle. Furthermore, the ball head and ball cup are universal damping ball head structures, which not only allow free rotation but also self-lock when rotation stops. Attached Figure Description

[0016] 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.

[0017] To address the problem that existing technologies often use fixed or limited hinged connections between the detection frame and the receiver host or handle, which makes it difficult to maintain the detection frame parallel to the ground or at the optimal detection angle when operating in complex terrain, leading to unstable signal reception, decreased detection accuracy, and requiring operators to constantly bend over or adjust their body posture to adapt to the terrain, increasing labor intensity and reducing detection efficiency, this embodiment provides the following technical solution: Example 1: As Figures 1-4 As shown, the device of this utility model mainly consists of a ball bowl base 1, a ball bowl 2, a ball head 3, and a handheld component. The ball bowl 2 is bolted to the lower end of the ball bowl base 1, and the ball head 3 is embedded within the ball bowl 2. A connecting flange 4 is installed on the protruding movable end of the ball head 3, and the path detector 5 is bolted to the connecting flange 4. A first connecting plate 101 is fixed to the outer surface of the ball bowl base 1, and integrally formed first connecting blocks 102 are provided on both sides of the first connecting plate 101. A second connecting plate 7 abuts against the first connecting plate 101, and second connecting blocks 701 are provided at corresponding positions on both sides of the second connecting plate 7. The first connecting blocks 102 and the second connecting blocks 701 are fixedly connected by bolts. An inclined plate 702 is installed at one end of the second connecting plate 7, and fixing blocks 703 are installed on both sides of the upper end of the inclined plate 702. Both ends of a damping rotating shaft 704 are installed on the fixing blocks 703. A connecting sleeve 705 is fixed to the middle section of the damping rotating shaft 704, and a threaded hole 706 is provided on the connecting sleeve 705. A threaded post 8 is screwed into the threaded hole 706. One end of the threaded post 8 is integrally set with the hand handle 801. A handle 802 is installed on the end of the hand handle 801 away from the threaded post 8.

[0018] During operation, the operator holds the handle 802. When adjusting the detection angle in complex terrain, the operator can apply forces in multiple directions to the path detector 5 due to the ball joint connection formed by the ball head 3 and the ball cup 2, causing the ball cup base 1 to rotate omnidirectionally relative to the ball head 3. Simultaneously, the entire ball joint assembly, ball cup base 1 and ball cup 2, can rotate horizontally relative to the hand lever 801 via the damping rotation shaft 704. This dual-degree-of-freedom design allows the path detector 5 to flexibly adapt to uneven ground and maintain the optimal detection posture. Once the angle is adjusted to the correct position, a certain self-locking friction force is generated between the ball head 3 and the ball cup 2 due to the omnidirectional damping structure, which can temporarily maintain the angle.

[0019] Example 2: Based on Example 1, to improve the durability and ease of operation of key components, the materials and some structures of this device are enhanced. The ball joint 2 is made of wear-resistant nylon material to ensure long-term smooth rotation and self-locking reliability of the ball joint; the handle 801 is made of aluminum alloy tube to reduce the overall weight; a handle bracket 201 is integrally provided on the outer surface of the ball joint 2, and a screwdriver 6 can pass through the through hole on the bracket for easy tightening or loosening of the connecting bolts on site.

[0020] When in operation, its basic angle adjustment and self-locking mechanism are exactly the same as in Embodiment 1. The enhanced materials make the device more durable in harsh outdoor environments. The additional handle bracket 201 and the readily available screwdriver 6 facilitate quick assembly and disassembly of the path detector 5 or fastening of connecting parts, further improving the efficiency of fieldwork.

[0021] The working principle summarized above is as follows: First, the operator securely mounts the path detector 5 onto the ball joint 3 via the connecting flange 4. During operation, the operator holds the handle 802 and brings the path detector 5 close to the ground to be measured. When encountering uneven terrain, the pitch and tilt angles of the path detector 5 are adjusted via the universal ball joint structure ball joint 3 and ball cup 2, while its horizontal orientation can be adjusted via the damping rotation shaft 704. The built-in damping of the ball joint structure provides tactile feedback during adjustment and temporary self-locking after releasing the handle at any angle. For conditions requiring complete locking, the damping friction of the universal damping ball joint ultimately fixes the angle. This practical application achieves flexible and stable adjustment with multiple degrees of freedom through a purely mechanical structure, effectively ensuring detection accuracy and significantly reducing the operator's workload.
