[0031] Example 1:
[0032] Reference Figure 1 This utility model discloses an adjustable sub-frame adjustment block 1, which is disposed in the gap between the energy-saving sub-frame 2 and the wall. (See reference...) Figure 2 The sub-frame adjustment block 1 includes an adjustment block base 11 and an adjustment block body 12 that is detachably fixed on the adjustment block base 11. An adjustment screw 13 is installed inside the adjustment block base 11, and one end of the adjustment screw 13 is threadedly connected to the adjustment block body 12. Rotating the adjustment screw 13 adjusts the position of the adjustment block body 12 on the adjustment block base 11, thereby changing the thickness of the sub-frame adjustment block 1.
[0033] Reference Figure 5 and Figure 6 The adjusting block body 12 has a nut 14 installed inside, and the adjusting screw 13 is threadedly connected to the nut 14. The adjusting screw 13 is an M6 socket head cap screw, and the nut 14 is an M6 nut. (Refer to...) Figure 9 and Figure 10 A limiting groove 113 is provided on the base 11 of the adjusting block, and the head of the adjusting screw 13 is embedded in the limiting groove 113. A ramp 115 is provided on one side of the inner wall of the limiting groove 113.
[0034] Reference Figure 3 and Figure 4 The base 11 of the adjusting block has a first inclined surface 111 on one side, and the body 12 of the adjusting block has a second inclined surface 121 on one side that slides with the first inclined surface 111. The first inclined surface 111 has a first anti-slip tooth 112, and the second inclined surface 121 has a second anti-slip tooth 122 that cooperates with the first anti-slip tooth 112.
[0035] The adjusting block base 11 extends outward on both sides of the first inclined surface 111 to form skirts 114 (see...). Figure 3 The adjusting block body 12 is fixedly connected to buckles 123 on both sides of the second inclined surface 121, which are engaged with the skirt edge 114 (see...). Figure 4 ).
[0036] This is an adjustable sub-frame adjustment block 1. There is a gap between the sub-frame and the wall opening. The sub-frame adjustment block 1 is inserted into the gap to fill the gap and level the sub-frame.
[0037] During assembly, the latches 123 vertically engage with the skirts 114 on both sides of the base 11 of the adjusting block from top to bottom. The latches 123 open outwards in a slightly deformed state. After engaging with the skirts 114, the latches 123 return to their initial state, and the sub-frame adjusting block 1 is assembled. During the adjustment of the sub-frame adjusting block 1, this latch structure prevents it from wobbling left or right, acting as a limit. It also ensures precise vertical movement of the sub-frame adjusting block 1.
[0038] The limiting structure for the M6 socket head cap screw head on the sub-frame adjusting block base is the ramp 115 in the limiting groove 113 mentioned above. When the M6 socket head cap screw is rotated clockwise, this ramp 115 guides the M6 socket head cap screw head to move upwards, making it easier to rotate the M6 socket head cap screw with an Allen wrench. When the M6 socket head cap screw is rotated counterclockwise, this ramp 115 guides the M6 socket head cap screw head to move downwards. This limiting structure prevents the M6 socket head cap screw and M6 nut from separating and falling off.
[0039] The adjusting block base 11 and the adjusting block body 12 are connected to each other using M6 hex socket screws and M6 nuts. (Refer to...) Figure 11 The secondary frame adjustment blocks 1 are used alternately on the indoor and outdoor sides to make the secondary frame more stable under force, making it easier to level and reach the set state, and improving the load-bearing effect.
[0040] Product differences: The conventional sub-frame adjustment block 1 can only be used alone or multiple blocks can be stacked together, and its height adjustment function is not as convenient as the current sub-frame adjustment block 1.
[0041] The implementation principle of this utility model is as follows: This utility model discloses an adjustable sub-frame adjustment block. During installation, the sub-frame adjustment block 1 is inserted into the gap between the sub-frame and the wall opening. An M6 hex wrench is used to rotate the M6 hex screw clockwise. The M6 hex screw and M6 nut work together to cause the adjustment block body 12 to rise along the adjustment block base 11, thereby achieving the upward adjustment purpose of the adjustment block body 12 and increasing the overall thickness of the sub-frame adjustment block 1 (see...). Figure 7 and Figure 8 Using an M6 hex wrench, rotate the M6 hex screw counterclockwise. The M6 hex screw and M6 nut work together to lower the adjusting block body 12 along the adjusting block base 11, thereby achieving the purpose of downward adjustment of the adjusting block body 12 and reducing the overall thickness of the sub-frame adjusting block 1. This can quickly fill gaps and level the sub-frame, which is convenient and quick.
[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
