They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model is a portable and reusable seat belt attachment device, whose structure mainly includes an L-shaped screw 1, a connecting washer 2, a circular washer 4, an adjusting nut 3, and a fixing nut 5.

[0021] Among them, two L-shaped screws 1 are required for use together. The L-shaped screw 1 includes a through-wall rod 1-1 and an adjusting rod 1-2. The through-wall rod 1-1 and the adjusting rod 1-2 are an integral structure or are fixedly connected by welding. The through-wall rod 1-1 and the adjusting rod 1-2 are perpendicular to each other to form an L-shaped structure.

[0022] During the pouring and casting of the building structure, tie bolt holes 7 are left for connecting tie bolts. This utility model utilizes the existing tie bolt holes 7 on the building wall 6 to form the attachment points for safety belts. The through-wall rods 1-1 of the two L-shaped screw rods 1 are respectively inserted into the two tie bolt holes 7 of the building wall 6, with the through-wall rods 1-1 passing through the tie bolt holes 7 and the ends protruding for a certain length.

[0023] The end of the through-wall rod 1-1 is provided with an external thread, and the adjusting rod 1-2 is also provided with an external thread. The external thread at the end of the through-wall rod 1-1 is used to thread-connect and fix the nut 5, and the external thread on the adjusting rod 1-2 is used to thread-connect and adjust the nut 3.

[0024] Two through holes 2-1 are provided on the connecting gasket 2, and the through holes 2-1 are used to pass through the adjusting rod 1-2.

[0025] Install connecting washers 2 on the two adjusting rods 1-2. Thread two adjusting nuts 3 onto each adjusting rod 1-2. The two adjusting nuts 3 are located on both sides of the connecting washers 2. The connecting washers 2 are fixed by the adjusting nuts 3 on both sides of the connecting washers 2, thereby fixing the two adjusting rods 1-2 together.

[0026] A circular washer 4 is fitted onto the exposed end of the through-wall rod 1-1 and a fixing nut 5 is threaded onto it, forming a tensile structure through the fixing nut 5 and the circular washer 4.

[0027] Generally, only the end of the through-wall rod 1-1 has an external thread of a certain length, and the part of the through-wall rod 1-1 near the adjusting rod 1-2 is a smooth rod structure. The external thread of a certain length is used to adjust the relative position of the fixing nut 5 and the washer, so that this utility model can be applied to walls 6 of different thicknesses. The smooth rod part of the through-wall rod 1-1 is used to attach the hook of the safety belt.

[0028] The adjusting rods 1-2 are generally fully threaded rods, which give them a large adjustment range to accommodate the tie bolt holes 7 with different spacing on the wall 6.

[0029] To ensure safety, two fixing nuts 5 are threaded to the end of each through-wall rod 1-1 to provide sufficient tensile strength.

[0030] Specifically, the connecting gasket 2 is an 8-shaped gasket.

[0031] Among them, the fixing nut 5 and the adjusting nut 3 are both flange nuts.

[0032] like Figure 4 As shown, in one embodiment of this utility model, a limiting structure 8 is also provided on the through-wall rod 1-1. The limiting structure 8 and the fixing nut 5 can fix the through-wall rod 1-1 to the wall 6, and after fixing, it can prevent the through-wall rod 1-1 from moving axially. The limiting structure 8 can be a ring of protrusions on the through-wall rod or a gasket structure welded to the through-wall rod, etc.

[0033] The method of using this utility model is as follows: First, screw an adjusting nut 3 into each of the two adjusting rods 1-2. Then, pass the two adjusting rods 1-2 through the two through holes 2-1 of the connecting washer 2, facing each other. Adjust the position of the connecting washer 2 according to the spacing of the two tie bolt holes 7 on the wall 6 at the predetermined position. Then, insert an adjusting nut 3 into each of the two adjusting rods 1-2 and fix the connecting washer 2 by adjusting the nuts 3 on both sides of the connecting washer 2. Pass the two through-wall rods 1-1 with the adjusted spacing through the two tie bolt holes 7 of the wall 6. Fit a circular washer 4 onto the exposed end of the through-wall rod 1-1 and insert a fixing nut 5 to complete the fixing of the safety belt hanging point of this utility model. When using the hanging point, hang the hook of the safety belt on the bare part of the through-wall rod 1-1.
