When the screw rod 8 rotates, the connecting plate 11 can be driven to move, and an arc-shaped clamping plate 12 is arranged on one side of the connecting plate 11;

[0037] A vertical rod is fixedly arranged on one side of the upper surface of the bottom plate 1 close to the second support column 10, a connecting plate 11 is arranged on the top of the vertical rod, and an arc-shaped clamping plate 12 is arranged on the top of the connecting plate 11;

[0038] A connecting rod is fixedly arranged between the bottoms of the two first support columns 4, a connecting plate 11 is arranged on the top of the connecting rod, and an arc-shaped clamping plate 12 is arranged on the top of the connecting plate 11;

[0040] The center of the connecting plate 11 on the connecting rod corresponds vertically to the center of the connecting plate 11 connected to the fixing plate 7 connected to the top end of the first supporting column 4;

[0041] The connecting plate 11 on the vertical plate and the connecting plate 11 on the connecting rod are in the same horizontal direction;

[0042] One end of the screw rod 8 away from the rotating block 5 is threadedly connected to the connecting plate 11 .

[0043] The movement of the connecting plate 11 can drive the arc-shaped clamping plate 12 to move, and the outer wall of the HVAC pipe can be clamped by the movement of the arc-shaped clamping plate 12;

[0044] The rotating blocks 5 arranged on both sides of the first support column 4 and the second support column 10 are symmetrically structured relative to the center line of the top plate 9. By rotating the rotating blocks 5, the screw rod 8 can be driven to rotate together, which is convenient for clamping the HVAC pipe. After the HVAC pipe is clamped and fixed, it is convenient to connect.

[0045] A buffer mechanism 6 is provided between the connecting plate 11 and the side wall of the arc-shaped clamping plate 12, and three groups of buffer mechanisms 6 are provided. The three groups of buffer mechanisms 6 can adjust the tightness of the clamping when the arc-shaped clamping plate 12 clamps the HVAC pipe, thereby effectively protecting the outer wall of the HVAC pipe.

[0046] The buffer mechanism 6 includes a second slide groove 601, a fixed block 602, a first connecting spring 603, a sliding plate 604, and a second connecting spring 605. One side of the fixed block 602 is fixedly connected to the side wall of the connecting plate 11. The second slide groove 601 is provided on both sides of the interior of the fixed block 602. The sliding plate 604 is slidably connected inside the second slide groove 601. One end of the first connecting spring 603 is fixedly connected to the inner side wall of the fixed block 602, and the other end of the first connecting spring 603 is fixedly connected to one side of the sliding plate 604. One end of the second connecting spring 605 is fixedly connected to the inner side wall of the fixed block 602. The first end of the second connecting spring 605 is fixedly connected to the side of the sliding plate 604 away from the first connecting spring 603, and the other end of the second connecting spring 605 is fixedly connected to the side wall of the arc-shaped clamping plate 12. When the HVAC pipe is clamped, the force applied to the second connecting spring 605 slides inward on the inner side of the second sliding groove 601 through the sliding plate 604, so that the first connecting spring 603 can be compressed. Then, the second connecting spring 605 and the first connecting spring 603 cooperate with each other to provide buffer protection for the clamping of the HVAC pipe and reduce the wear of the HVAC pipe.

[0047] A first slide groove 2 is provided at one end of the top of the base plate 1, and an adjustment mechanism 3 is provided at one end inside the first slide groove 2. The adjustment mechanism 3 includes a driving motor 301, a slider 302, a threaded groove 303 and a threaded rod 304. The driving motor 301 is fixedly installed on the inner wall of the base plate 1, and the output end of the driving motor 301 is connected to the threaded rod 304. After the driving motor 301 is powered on and started, the threaded rod 304 can be rotated. A slider 302 is provided on the outer wall of the threaded rod 304, and a threaded groove 303 is provided inside the slider 302. A threaded connection structure is formed between the threaded rod 304 and the inner side of the threaded groove 303. When the outer wall of the threaded rod 304 is threadedly connected to the inner wall of the threaded groove 303, the rotation of the threaded rod 304 can drive the slider 302 to move back and forth left and right on the inner side of the first slide groove 2, and the movement of the slider 302 can drive the first support column 4 to move left and right. The position of the first support column 4 can be adjusted according to the length of the HVAC pipe, thereby improving the practical performance of the clamp.

[0048] Working principle: When in use, first rotate the rotating block 5, the rotating block 5 drives the screw rod 8 to rotate, the rotation of the screw rod 8 drives the connecting plate 11 to move, the movement of the connecting plate 11 drives the arc clamping plate 12 to move synchronously, until the arc clamping plate 12 is clamped and fixed on the outer wall of the HVAC pipe. The arc clamping plate 12 can clamp and fix the outer wall of the HVAC pipe up, down, left, and right, and the fixing effect is good;

[0049] Secondly, the position of the first support column 4 is adjusted according to the length of the HVAC pipe, and the driving motor 301 is started by an external power supply to rotate the threaded rod 304. Under the connection between the outer thread of the threaded rod 304 and the inner thread of the thread groove 303, the rotation of the threaded rod 304 can drive the slider 302 to move left and right inside the first slide groove 2, and the movement of the slider 302 can drive the first support column 4 to move synchronously. When the first support column 4 is adjusted to a suitable position, the HVAC pipe is clamped, which improves the flexibility of the device.

[0050] Finally, when clamping the HVAC pipe, the second connecting spring 605 is forced to make the sliding plate 604 slide inward on the inner side of the second sliding groove 601. When the sliding plate 604 slides toward the inner side of the fixed block 602, the first connecting spring 603 is compressed. When the arc-shaped clamping plate 12 clamps the HVAC pipe, the cushioning effect is increased to avoid wear of the outer wall of the HVAC pipe due to excessive clamping, thereby providing protection for the HVAC pipe when clamping.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
