[0028] Example 1:
[0029] like Figures 1 to 4 As shown in the figure, this embodiment provides a convenient, non-drilling adjustable square column template fastener, including: a square column 1 and a fastening mechanism 2. The fastening mechanism 2 includes a fastening frame 1 211 arranged on one side of the square column 1. A rotating shaft 21 is rotatably provided on one side of the fastening frame 1 211, and a fastening frame 212 is rotatably provided on the rotating shaft 21. A fastening frame 4 222 is provided on the side of the square column 1 away from the fastening frame 1 211, and a rotating shaft 22 is rotatably provided on one side of the fastening frame 4 222. A fastening frame 3 221 is also provided on the rotating shaft 22. Fixing components are provided on the fastening frame 4 222, the fastening frame 3 221, the fastening frame 1 211, and the fastening frame 212.
[0030] In this embodiment, the square column 1 and the fastening mechanism 2 are the convenient, non-drilling adjustable square column template fastener device involved in the cost application, realizing a convenient, non-drilling adjustable square column template fastener.
[0031] In this embodiment, a fastening frame 212 is rotatably connected to the rotating shaft 21. The fastening frame 212 and the fastening frame 211 cooperate with each other. When it is necessary to fasten the square column, the fastening frame 212 can be rotated to fit against the other side of the square column, preparing for subsequent fixing operations.
[0032] In this embodiment, a fastening frame 221 is provided on the rotating shaft 22. The fastening frame 221 and the fastening frame 222 cooperate with each other to fasten the square column from the other side, forming an all-round fastening system for the square column 1 with the fastening frame 1 211 and the fastening frame 212.
[0033] It should be noted that the fastening frame 211 is arranged on one side of the square column 1 and can be made of high-strength steel or aluminum alloy material. It has good compressive and bending resistance and can withstand the large pressure applied during the fastening process.
[0034] Specifically, the fixing components include: a fastening groove 223, arranged on the fastening frame four 222 and the fastening frame three 221, for fastening frame one 211 and the fastening frame two 212 to slide inside; pin holes two 225, provided in multiple sets, all arranged on the surface of the fastening frame three 221 and the fastening frame four 222; pin holes one 214, provided in multiple sets, all arranged through the fastening frame two 212 and the fastening frame one 211; and a fastening pin 23, which slides through the pin holes two 225 and the pin holes one 214.
[0035] In this embodiment, fastening frame one 211 and fastening frame two 212 are slid to a suitable position through fastening groove 223, and then further fixed using pin holes and fastening pins.
[0036] Specifically, the fourth fastening frame 222 and the third fastening frame 221 are hinged together by the second rotating shaft 22, and the second fastening frame 212 and the first fastening frame 211 are hinged together by the first rotating shaft 21. The second fastening frame 212 slides inside the fastening groove 223 provided in the fourth fastening frame 222, and the first fastening frame 211 slides inside the fastening groove 223 provided in the third fastening frame 221, for clamping the square post 1.
[0037] As a preferred embodiment, the fastening frame 1 211 slides inside the fastening groove 223 provided in the fastening frame 3 221, thereby enabling the clamping function of square columns of different sizes and improving the versatility and adjustability of the fastener.
[0038] Example 2:
[0039] Based on Example 1, in order to further clamp the square post 1, a fastening pin 23 is slidably provided inside the pin hole 214 and the pin hole 225;
[0040] Specifically, the fastening pin 23 is in the shape of a flat triangle and is used to insert into the pin hole 214 and the pin hole 225.
[0041] It should be noted that the fastening pin 23 is a flat triangular shape. Insertion can effectively connect different parts, enhance the stability of the fastening mechanism, and prevent relative displacement between the fastening frames.
[0042] Specifically, the fastening pins 23 are provided in multiple sets. By folding the fastening frame four 222 and fastening frame three 221 and folding the fastening frame two 212 and fastening frame one 211, the two sets of fastening pins 23 are inserted into the pin hole two 225 and the fastening frame two 212 respectively. This makes the inside of one set of fastening pins 23 abut against one side of fastening frame one 211 and the bottom of the other set of fastening pins 23 abut against one side of fastening frame three 221, thereby fixing the square column 1.
[0043] As a preferred implementation, by folding, the fastening frame 4 222 and fastening frame 3 221, and fastening frame 212 and fastening frame 1 211 are adjusted to the appropriate positions. Then, multiple sets of fastening pins 23 are inserted into pin holes 225 and fastening frame 212 respectively, so that the fastening pins 23 abut against one side of different frames to fix the square post 1.
[0044] Specifically, the inner sides of the fastening frame 3 221 and fastening frame 4 222, and the fastening frame 1 211 and fastening frame 2 212 all abut against the square post 1.
[0045] It should be noted that the inner sides of fastening frame 3 221 and fastening frame 4 222, and fastening frame 1 211 and fastening frame 2 212 are in contact with the surface of square column 1. Friction and pressure are generated through surface contact, which enhances the fastening.
[0046] Specifically, the square column 1 is in the shape of a rectangular column 1.
[0047] In this embodiment, the fastener is specifically designed for rectangular column 1, providing a suitable fastening solution and ensuring the applicability of the fastener.
[0048] When using the square column 1 template, if it needs to be tightened, the user takes out rotating shaft 1 21 and rotating shaft 22, folds fastening frame 1 211 and fastening frame 212 into an L-shape, and fastening frame 3 221 and fastening frame 4 222 in the same way. Rotating shaft 1 21 and rotating shaft 22 are attached to the two corresponding corners of square column 1, and fastening frame 1 211 and fastening frame 212 are passed through the corresponding fastening groove 223 respectively. After they are attached, the user passes the four-sided fastening pin 23 through the corresponding four-sided pin hole 1 214 and pin hole 225, and tightens it with a hammer.
[0049] 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.
