[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0032] Example 1

[0033] Reference Figure 1-3 This embodiment provides a portable hanging device, including a fixing assembly 100, including a fixing rod 101, a receiving chamber 102 inside the fixing rod 101, and a winding component 103 inside the receiving chamber 102; a stud 101a is provided at the bottom of the fixing rod 101; the receiving chamber 102 is located at the top of the fixing rod 101, and an arc-shaped plate 102a is symmetrically provided in the middle of the receiving chamber 102; a locking rod 102b is provided at the axis of the receiving chamber 102; the winding component 103 includes a ruler spring 103a and a hanging rope 103b, and a collar 103a-1 is provided at one end of the ruler spring 103a, which is fixed to one end of the hanging rope.

[0034] Specifically, threaded holes are reserved at the top of large equipment such as generator sets. The stud 101a at the bottom of the fixing rod 101 is engaged with the threaded hole. Rotating the fixing rod 101 inserts the stud 101a into the threaded hole to achieve reliable fixing of the fixing rod 101.

[0035] Preferably, one end of the ruler spring 103a is fixed to the locking rod 102b, and the other end passes through the gap between the two arc-shaped plates 102a and extends out. One end of the hanging rope 103b is fixed by the collar 103a-1 on the ruler spring 103a and then wrapped around the outer wall of the arc-shaped plate 102a. After that, the hanging rope 103b extends out of the fixing rod 101. The arc-shaped plate 102a is rotatably connected to the accommodating chamber 102.

[0036] Furthermore, there are two sets of winding components 103. The hanging rope 103b on one set of winding components 103 is fixed to the male end 200, and the hanging rope 103b on the other set of winding components 103 is fixed to the outer shell 301. The two sets of winding components 103 are arranged symmetrically.

[0037] During use, since one end of the hanging rope 103b is fixed to the ruler spring 103a, and the ruler spring 103a is fixed to the arc plate 102a, pulling the hanging rope 103b will cause the arc plate 102a to rotate. When the arc plate 102a rotates, the hanging rope 103b wrapped around its outer wall will extend out with the rotation of the arc plate 102a. Since both ends of the ruler spring 103a are fixed, the ruler spring 103a is gradually compressed as the arc plate 102a rotates. When the hanging rope 103b is released, the ruler spring 103a loses tension and gradually recovers, causing the arc plate 102a to reverse. When the arc plate 102a reverses, it will rewrap the pulled-out hanging rope 103b around its outer wall, which can realize the automatic winding of the hanging rope 103b.

[0038] By cooperating with the ruler spring 103a and the arc plate 102a, the hanging rope 103b can be fixed inside the fixing rod 101, and the hanging rope 103b can be automatically stored without the need to prepare a separate hanging rope 103b, thus improving the portability of the device.

[0039] Example 2

[0040] Reference Figure 3-6This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that: Male connector 200; the male connector 200 is sequentially provided with a first locking groove 201, a second locking groove 202, a push block 203, and a wiring groove 204; the second locking groove 202 is provided with an elliptical block 202a; the push block 203 is symmetrically arranged on the outer wall of the male connector 200; female connector assembly 300, including a housing 301, a movable stage 302 is provided inside the housing 301, and a rotating disk 303 is provided inside the movable stage 302. A push rod 304 is provided, which is connected to a locking block 305; a connecting cylinder 301a is provided at the center of the outer shell 301; a sealing plate 301b is provided on the front side of the outer shell 301; a vertical groove 301b-1 is symmetrically provided on the sealing plate 301b; an arc-shaped groove 301c is provided on the inner circumference of the sealing plate 301b; an arc-shaped spring 301c-1 is provided in the arc-shaped groove 301c; a spring 301d is provided at the bottom inside the outer shell 301; a rotating groove 301e is provided on the inner wall of the outer shell 301; an opening 301e-1 is provided at one end of the rotating groove 301e; the outer shell 301... 1. A wiring sleeve 301f is provided at the bottom; the movable platform 302 includes a limiting platform 302a and a base plate 302b. The movable platform 302 has a through hole 302c. The limiting platform 302a has symmetrically arranged slots 302a-1. The slots 302a-1 have pins 302a-2. The bottom of the pins 302a-2 has a telescopic spring 302a-3. One end of the limiting platform 302a is surrounded by a first connecting rod 302d. A second connecting rod 302e is provided on the limiting platform 302a near the through hole 302c. The base plate 302b has a groove. 302b-1; The rotating disk 303 has an arc hole 303a on its upper ring, the inner wall of the rotating disk 303 has a first connecting part 303b, the outer wall of the rotating disk 303 has a limiting post 303c, and the limiting post 303c has a spring block 303c-1 inside; the locking block 305 is sleeved on the second connecting rod 302e, and the locking block 305 has a second connecting part 305a; the push rod 304 is arc-shaped, one end of the push rod 304 is rotatably connected to the first connecting part 303b, and the other end of the push rod 304 is rotatably connected to the second connecting part 305a.

[0041] Specifically, the width of the rotating groove 301e matches the diameter of the limiting post 303c. The limiting post 303c can move within the rotating groove 301e. When the limiting post 303c is within the rotating groove 301e, the spring block 303c-1 is compressed. When the limiting post 303c moves to the opening, the spring block 303c-1 pops out and jams the limiting post 303c, preventing the limiting post 303c from continuing to move along the rotating groove 301e.

[0042] Preferably, the first connecting rod 302d is placed inside the arc hole 303a, and the locking block 305 is fixed by the second connecting rod 302e and rotates around the second connecting rod 302e.

[0043] Furthermore, when there is no external force, the moving stage 302 is pressed tightly against the sealing plate 301b by the restriction of the spring 301d. At this time, the limiting post 303c on the rotating disk 303 is located at one end of the rotating groove 301e, and the locking block 305 is also retracted into the rotating disk 301e.

[0044] When the male connector 200 is inserted into the outer casing 301, the end of the male connector 200 is inserted into the groove 302b-1. Continuing to push the male connector 200 causes the moving platform 302 to move inward and compress the spring 301d. The movement of the moving platform 302, in turn, causes the rotating disk 303 to move. Because the limiting post 303c on the rotating disk 303 is embedded in the rotating groove 301e, the rotating disk 303 rotates as it moves inward. The rotation of the rotating disk 303 causes the push rod 304 to push the locking block 305. The locking block 305 moves along the second connecting... The connecting rod 302e rotates and extends out of the rotating disk 303, eventually embedding into the first locking groove 201 of the male head 200 to complete the first fixation; as the moving stage 302 moves inward, the pin 302a-1 located in the slot 302a-1 is no longer restricted by the connecting cylinder 301a and pops out, finally extending into the second locking groove 202 of the male head 200 to complete the second fixation of the male head 200; when the male head 200 is fully inserted into the female head assembly 300, the push block 203 on the male head 200 is just embedded in the vertical groove 301b-1.

[0045] After the male head 200 is fully inserted into the female head assembly 300, the male head 200 can be fixed again, which can ensure the reliability of the connection of the hanging rope 103b and the safety of the staff at the hanging point.

[0046] Example 3

[0047] Reference Figure 1-9 This is the third embodiment of the present invention. This embodiment provides a portable attachment device. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: male head 200; female head assembly 300, including housing 301, a moving platform 302 is provided inside the housing 301, a rotating disk 303 is provided inside the moving platform 302, a push rod 304 is provided on the rotating disk 303, and the push rod 304 is connected to the locking block 305.

[0048] When it is necessary to disconnect the connection between the male connector 200 and the female connector assembly 300, simply rotate the male connector 200. At this time, the push block 203 inserted into the vertical slot 301b-1 rotates into the arc-shaped slot 301c and compresses the arc-shaped spring 301c-1. When the male connector 200 rotates, the longer end of the elliptical block 202a contacts the pin 302a-2. As the elliptical block 202a continues to rotate, it pushes the pin 302a-2 out of the second locking slot 202, completing one unlocking of the male connector 200. Then, press and hold the spring block 303c-1, causing it to retract into the limiting post 303c. The limiting post 303c can continue to move within the rotating slot 301e, allowing the rotating disk 303 to rotate again. After one unlocking, the compressed spring 301d opens. The moving platform 302 is pushed outward, and the movement of the moving platform 302 will drive the rotating disk 303 to move outward. Since the limiting post 303c can only move within the rotating groove 301e, the rotating disk 303 will also rotate when it moves outward. At this time, the direction of rotation of the rotating disk 303 is opposite to the direction of rotation of the rotating disk 303 when the male head 200 is inserted. The rotation of the rotating disk 303 will drive the push rod 304 to move. The movement of the push rod 304 will drive the locking block 305 to rotate into the rotating disk 303. The locking block 305 will no longer be inserted into the first locking groove 201, completing the second unlocking of the male head 200. At this time, the male head 200 can be taken out smoothly. After releasing the male head 200 and the female head assembly 300, the hanging rope 103b can be automatically retracted by the ruler spring 103a.

[0049] With the cooperation of the male head 200 and the female head assembly 300, the second unlocking can be completed simply by rotating the male head 200 and pressing the spring block 303c-1, which greatly improves work efficiency.
