DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: A simple portable safety belt hanging point device, such as Figure 1 The hanging rod 3 is used to pass through the reserved hole 2 on the wall 1, and the reserved hole 2 is a left-right transparent structure.

[0026] The left end of the hanging rod body 3 is integrally bent to form a hanging ring 302, and the right end of the hanging rod body 3 is welded with a stopper 4, the diameter of which is smaller than the inner diameter of the reserved hole 2 and larger than the diameter of the hanging rod body 3.

[0027] A double-hole hanging ring 5 is hung on the hanging point rod body 3, and the double-hole hanging ring 5 includes a first ring hole 501 and a second ring hole 503 spaced apart from each other. The bottom of the first ring hole 501 is connected to the top of the second ring hole 503 to form a slideway 502.

[0028] The inner diameter of the first annular hole 501 is equal to the outer diameter of the hanging point rod 3, and the outer diameter of the first annular hole 501 is larger than the inner diameter of the reserved hole 2. The transverse width of the slideway 502 is equal to the outer diameter of the hanging point rod 3, and the transverse width of the slideway 502 is smaller than the inner diameter of the first annular hole 501. The inner diameter of the second annular hole 503 is equal to the outer diameter of the stopper 4.

[0029] In order to facilitate the first ring hole 501 to be automatically located above the second ring hole 503 when the double-hole hanging ring 5 naturally droops after installation, in this embodiment, the center of gravity of the double-hole hanging ring 5 is located below the upper and lower height bisectors thereof.

[0030] In order to prevent the hanging point rod body 3 from moving left and right in the reserved hole 2 during use, Figure 1 As shown, a threaded section 301 is provided on the hanging point rod body 3, and a fastening nut 8 is sleeved on the threaded section 301 and threadedly connected thereto. The fastening nut 8 is located on the left side of the reserved hole 2, and the outer diameter of the fastening nut 8 is larger than the inner diameter of the reserved hole 2.

[0031] Working principle: When in use, pass the right end of the hanging point rod body 3 and the stop block 4 through the reserved hole 2, and then pass the double-hole hanging ring 5 through the second ring hole 502 and the stop block 4. Then, move the double-hole hanging ring 5 downward to make the hanging point rod body 3 slide from the second ring hole 502 through the slide 502 into the first ring hole 501. Since the inner diameter of the first ring hole 501 is smaller than the diameter of the stop block 4, and the outer diameter of the first ring hole 501 is larger than the outer diameter of the reserved hole 2, the double-hole hanging ring 5 can quickly form an effect of preventing the hanging point rod body 3 from falling out of the reserved hole 2.

[0032] Then, the fastening nut 8 is rotated, and the block 4 presses the double-hole hanging ring 5 against the wall 1 to prevent the hanging point rod 3 from moving left and right in the reserved hole 2 and the double-hole hanging ring 5 from rotating during use.

[0033] Example 2: A simple portable safety belt hanging point device, in order to prevent the hanging point rod 3 from accidentally re-entering the second ring hole 503 along the slide 502 from the first ring hole 501 during use, causing the hanging point rod 3 and the stopper 4 to accidentally fall out of the second ring hole 503, in this embodiment, as shown in FIG. Figure 3 As shown, a first receptacle 504 with a rearward opening is defined on the front side of the slideway 502, and a second receptacle 505 with front-to-back transparency is defined on the rear side of the slideway 502. The first and second receptacles 504 and 505 correspond front to back, and are both arranged slanted from front to back and from bottom to top. A retaining rod 6 is movably and obliquely inserted into the second receptacle 505. One end of the retaining rod 6 passes through the slideway 502 and is inserted into the first receptacle 504. The other end of the retaining rod 6 extends to the exterior of the double-hole hanging ring 5. A handle 7 is fixed to the end of the retaining rod 6 that extends outside the double-hole hanging ring 5. The remaining structure is the same as in Example 1.

[0034] Example 3: A simple portable safety belt attachment point device. In this embodiment, the inner diameter of the first annular hole 501 is larger than the outer diameter of the attachment point rod 3 and smaller than the diameter of the stopper 4. The lateral width of the slideway 502 is larger than the outer diameter of the attachment point rod 3, and the inner diameter of the second annular hole 503 is larger than the outer diameter of the stopper 4. The lateral width of the slideway 502 is smaller than the inner diameter of the first annular hole 501. The rest of the structure is the same as in Example 1.

[0035] Example 4: A simple portable safety belt hanging point device, in this example, the threaded section 301 and the fastening nut 8 are not provided. The other structures are the same as those in Example 1.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
