Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to an adjustable three-way fastener. Background Art

[0002] Fasteners are particularly important building materials in engineering construction, especially in the scaffolding construction process, as an indispensable auxiliary material. However, nowadays there are only fasteners that fix two steel pipes, that is, the fixation of steel pipes in two directions. For the corner parts in three directions, welding or other reinforcement forms are required for fixation, resulting in a certain amount of resource waste. How to achieve the fixation of steel pipes in three directions is a technical doubt of fasteners.

[0003] After searching, the applicant discovered a Chinese patent for "a steel pipe scaffolding fastener" with the publication (announcement) number "CN202644970U." This patent primarily uses a single fastener to connect and secure three steel pipes in three different directions, making installation and disassembly easy and reducing production and construction costs. However, the fastener's tab can only secure steel pipes of a specific size, limiting its scope of use. Furthermore, long-term contact between the tab and the steel pipe can easily lead to frictional damage. Therefore, we propose an adjustable three-way fastener. Utility Model Content

[0010] As a preferred solution, a second threaded hole is passed through the side of the tongue away from the adapter groove. The size of the second threaded hole is consistent with that of the first threaded hole. The internal thread of the second threaded hole is connected to a fixing bolt, and a slot is provided on the inner wall of the tongue.

[0011] As a preferred solution, the connecting block is inserted into the card slot.

[0012] Features and beneficial effects of this utility model:

[0025] One end of the connector 505 has a threaded outer wall, while the other end does not. The threaded end is threadedly connected to the third threaded hole 504, and the unthreaded end is rotatably connected to the rotating hole 507. The protective sleeve 506 is also replaced according to the size of the steel pipe. The clamping diameter can be changed according to the length of the connector 505, thereby increasing the scope of application and reducing the friction between the tongue 403 and the steel pipe.

[0026] Specifically, the distance between the protective sleeve 506 and the adjustment frame 501 can be changed by rotating the connecting piece 505 on the third threaded hole 504 in the limit block 503, thereby adapting to steel pipes of different diameters and improving the use range of the fastener. At the same time, the protective sleeve 506 can be used to protect the steel pipe to avoid wear caused by friction between the steel pipe and the fastener. The protective sleeve 506 is also easy to replace.

[0027] Example 2:

[0028] Please see the attached Figure 1 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 6 , and on the basis of Example 1, it is further obtained that a locking mechanism 4 is provided on the outside of the pipe groove 2, and the locking mechanism 4 includes a fixing piece 401, which is fixedly installed on the fastener body 1, and oranges 402 are fixedly installed on both sides of the fixing piece 401, and a rotating frame 405 is rotatably connected to the outer wall of the orange 402, and a tongue 403 is fixedly installed on the side of the rotating frame 405, and an adapting groove 404 is provided on the side of the tongue 403 and the rotating frame 405 close to the fixing piece 401, and a second threaded hole 406 is penetrated on the side of the tongue 403 away from the adapting groove 404, and the size of the second threaded hole 406 is consistent with that of the first threaded hole 3, and a fixing bolt 407 is threadedly connected to the internal thread of the second threaded hole 406, and a slot 408 is provided on the inner wall of the tongue 403, and the clamping block 502 is inserted into the inside of the slot 408.

[0029] The angles between the pipe grooves 2 are all ninety degrees. The adapter groove 404 ensures that the tongue 403 is not restricted when rotating along the orange 402. The initial diameter of the tongue 403 is designed to be the largest of commonly used steel pipes. The groove 408 is particularly non-slip, and the clamping block 502 is difficult to move after being inserted into the groove 408.

[0030] Specifically, the tongue 403 can be rotated along the orange 402 to clamp the steel pipe in the space formed by the tongue 403 and the pipe groove 2, and fixed by the fixing bolt 407. At the same time, the three sets of locking mechanisms 4 can fix the steel pipe at the corners in three directions, thereby improving the installation efficiency.

[0031] Working principle of the utility model: The utility model is an adjustable three-way fastener. First, a protective sleeve 506 of a suitable steel pipe size is selected and sleeved on the outer wall of the steel pipe. Then, the rotating frame 405 is rotated along the orange 402 so that the tongue 403 is close to the fastener body 1. The clamping block 502 is inserted into the clamping groove 408 to connect the adjustment frame 501 with the tongue 403. The steel pipe with the protective sleeve 506 is inserted into the circular hole formed by the tongue 403 and the pipe groove 2. Finally, the connecting piece 505 is slowly unscrewed from the third threaded hole 504 until its outer end completely enters the rotating hole 507 of the protective sleeve 506. The fixing bolt 407 is tightened inside the second threaded hole 406 and the first threaded hole 3 to fix and limit the steel pipe.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
