[0032] 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.

[0033] Example: Reference Figures 1-5 The portable equipment safety inspection device shown includes a telescopic support rod 1 with adjustable length, a detection head 2 installed at the upper end of the telescopic support rod 1, and an operation box 3 installed at the lower end of the telescopic support rod 1. The operation box 3 is equipped with a telescopic operation part 4, which is used to adjust the overall length of the telescopic support rod 1.

[0034] The upper end of the telescopic support rod 1 is rotatably connected to the detection head 2 through the movable connecting mechanism 5. The movable connecting mechanism 5 is used to drive the detection head 2 to rotate along its own central axis. The rotation angle of the detection head 2 is greater than 180°.

[0035] The operation box 3 is also equipped with a rotating operation unit 6, which is used to control the movable connecting mechanism 5 to drive the detection head 2 to rotate.

[0036] Based on the above structure, the operator can control the movable connecting mechanism 5 to drive the detection head 2 to rotate by rotating the operating part 6, thereby changing the orientation of the detection head 2. This allows the detection head 2 to be inserted into the cable from multiple directions to perform leakage detection on the cable. This enables the portable equipment safety inspection device to meet the needs of inserting cables from multiple directions, improving its flexibility and applicability during use, and bringing convenience to the inspection operation.

[0037] It should be noted that the specific structure and working principle of the telescopic support rod 1, the detection head 2, the operation box 3, and the telescopic operation part 4 are all existing technologies (refer to the structure and working principle disclosed in the patent documents with announcement number "CN212160043U" or "CN209373018U"), which are well known to those skilled in the art, and will not be described in detail here.

[0038] Furthermore, the active connection mechanism 5 includes:

[0039] Connecting block 51, the lower end of connecting block 51 is fixed to the top of the movable end of telescopic support rod 1, and an installation cavity 511 is provided inside the connecting block 51, with openings at both the upper and lower ends of the installation cavity 511.

[0040] The arc-shaped support 52 is integrally formed with the upper end of the connecting block 51. The arc-shaped support 52 is an arc-shaped plate structure that fits the outer arc surface of the detection head 2. The arc-shaped support 52 is slidably connected to the detection head 2.

[0041] The drive gear 53 is rotatably mounted in the mounting cavity 511, with its upper end extending out of the upper opening of the mounting cavity 511.

[0042] A transmission assembly is used to drive the drive gear 53 to rotate in accordance with the operation of the rotating operating unit 6;

[0043] Among them, the outer side wall of the detection head 2 is provided with an arc-shaped toothed groove 21 that meshes with the drive gear 53 for transmission;

[0044] The transmission components include:

[0045] Two winding wheels 54 are provided and are respectively located on both sides of the drive gear 53. Both winding wheels 54 are coaxially fixed to the drive gear 53 via a connecting shaft 55.

[0046] The drive rope 56 has its two ends wound around two winding wheels 54 respectively, and its middle part is wound around the rotating operating part 6 and rotated by the rotating operating part 6.

[0047] The rotating operation unit 6 includes a drive shaft 61 and a winding wheel 62. The drive shaft 61 is rotatably connected to the inside of the operation box 3. One end of the drive shaft 61 extends to the outside of the operation box 3 and is provided with a throttle. The winding wheel 62 is fixedly sleeved on the drive shaft 61. The drive rope 56 is wound around the drive shaft 61 in the middle and wound at least twice.

[0048] When the orientation of the detection head 2 needs to be adjusted, the operator only needs to rotate the drive shaft 61, which drives the winding wheel 62 to rotate. When the winding wheel 62 rotates, it pulls the drive rope 56 to one side, causing one of the winding wheels 54 to rotate. When one winding wheel 54 rotates, it drives the drive gear 53 and the other winding wheel 54 to rotate synchronously through the connecting shaft 55. When the other winding wheel 54 rotates, it winds up the excess drive rope 56 on the other side. The rotation of the drive gear 53 drives the detection head 2 to rotate through the arc-shaped toothed groove 21, thereby changing the orientation of the detection head 2. This achieves the purpose of adapting to the cable insertion requirements under different conditions, and the operation is simple and convenient.

[0049] Furthermore, the side walls on both the front and rear sides of the arc-shaped support 52 are integrally formed with side support plates 521, and the two side support plates 521 are attached to the front and rear sides of the detection head 2.

[0050] The edge of the side support plate 521 is fixedly formed with an arc-shaped retaining strip 522, and the front and rear sides of the detection head 2 are provided with a retaining groove 22 that slides and cooperates with the arc-shaped retaining strip 522.

[0051] The side support plate 521 and the arc-shaped retaining strip 522 are designed to allow the arc-shaped support 52 to slide and connect with the detection head 2, so that the detection head 2 will not detach from the arc-shaped support 52 when changing its angle, and the detection head 2 will be more stable during rotation.

[0052] Furthermore, the extension length of the arc-shaped support 52 is less than one-third of the extension length of the arc-shaped arm of the detection head 2, the extension angle of the arc-shaped support 52 is less than 90° and greater than 35°, and the rotation angle of the detection head 2 is a maximum of 270°, thereby meeting the insertion requirements of most cables (except for inverted insertion, it can be inserted at an angle, on both sides and at the top), thereby further improving the adaptability of the portable equipment safety inspection device and enhancing its flexibility in use.

[0053] The working principle of this utility model is as follows: In daily use, the operator only needs to rotate the drive shaft 61, which drives the winding wheel 62 to rotate. When the winding wheel 62 rotates, it pulls the drive rope 56 to one side, causing one of the winding wheels 54 to rotate. When one winding wheel 54 rotates, it drives the drive gear 53 and the other winding wheel 54 to rotate synchronously through the connecting shaft 55. When the other winding wheel 54 rotates, it winds up the excess drive rope 56 on the other side. Due to the setting of the side support plate 521 and the arc-shaped locking strip 522, the arc-shaped support 52 is slidably connected to the detection head 2. The rotation of the drive gear 53 drives the detection head 2 to rotate through the arc-shaped toothed groove 21, thereby changing the orientation of the detection head 2. This allows the detection head 2 to change its opening orientation within a maximum range of 270°, ultimately adapting to the cable insertion requirements under different conditions and performing leakage detection on the cable. This makes the portable safety inspection device applicable to multiple directions of cable insertion, improving its flexibility and applicability, and bringing convenience to the inspection operation.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
