[0012] The advantages of this utility model are:

[0013] 1. This utility model uses a first screw and a second screw structure to fix the mounting bracket to the ceiling with bolts. Then, the heating and ventilation pipes are fixed between the fixed base and the fixed plate, so that the fixed base and the fixed plate support the heating and ventilation pipes. Then, the first knob and the second knob can be rotated to drive the two fixed bases to slide left and right through the first screw, thereby changing the position of the fixed bases so that they can be adjusted according to the gap of the heating and ventilation pipes, thus improving the practicality of the bracket.

[0014] 2. Through the structural design of the transmission mechanism, this utility model can drive the sliding push block to move the second knob to the right and drive the two transmission plates to move to opposite sides, so that the transmission plates enter the clamping groove, thereby restricting the second knob.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 As shown, the pipe fixing device for HVAC engineering includes a base plate 1. Two mounting brackets 2 are fixedly connected to both sides of the top of the base plate 1. Two fixed bases 3 located between the two mounting brackets 2 are slidably connected to the top of the base plate 1. A fixing plate 4 is fixedly connected to the top of the fixed base 3 by bolts. A first screw 5 and a second screw 6 are threadedly connected to the inside of the two fixed bases 3 respectively. One end of the first screw 5 and the second screw 6 are rotatably connected to the mounting bracket 2. The right side of the first screw 5 is rotatably connected to the left side of the second screw 6. A first knob 7 is fixedly connected to the top of the first screw 5. A second knob 8 is slidably connected to the outside of the second screw 6. A transmission mechanism is slidably connected inside the second knob 8.

[0024] During operation, the mounting bracket 2 is fixed to the ceiling with bolts. Then, the HVAC pipes are fixed between the fixed base 3 and the fixed plate 4, so that the fixed base 3 and the fixed plate 4 support the HVAC pipes. Then, the first knob 7 and the second knob 8 can be rotated, so that the first screw 5 drives the two fixed bases 3 to slide left and right, thereby changing the position of the fixed bases 3. This allows them to be adjusted according to the gap of the HVAC pipes, improving the practicality of the bracket.

[0025] Furthermore, the transmission mechanism includes a first toothed plate 901, a transmission plate 902 is fixedly connected to one side of the first toothed plate 901, one side of the transmission plate 902 extends into the interior of the first screw 5, and a gear 903 is meshed with the other side of the first toothed plate 901. The end of the gear 903 is rotatably connected to the inner wall of the second knob 8 through a rotating shaft.

[0026] Furthermore, a second toothed plate 904 is meshed with one side of the gear 903, and a sliding push block 905 is fixedly connected to one side of the second toothed plate 904. The sliding push block 905 is slidably connected to the top and bottom of the second knob 8.

[0027] During operation, pushing the sliding push block 905 can move the second knob 8 to the right. When the second knob 8 moves to the right, due to the restriction of the first screw 5, the sliding push block 905 will not initially move the transmission plate 902 in the vertical direction. After the second knob 8 moves the transmission plate 902 away from the inside of the first screw 5, the sliding push block 905 continues to move to the right, which will move the two transmission plates 902 to opposite sides, so that the transmission plates 902 enter the locking groove 10, thereby restricting the second knob 8. At this time, the first knob 7 or the second knob 8 can be rotated alone, so that the first screw 5 or the second screw 6 can be rotated independently, making the adjustment of the distance between the two fixed bases 3 more flexible.

[0028] Furthermore, the interior of the second screw 6 is hollow, and two locking grooves 10 are provided at the top and bottom of the left side of the second screw 6. The two locking grooves 10 are symmetrically arranged, and an opening for the transmission plate 902 to enter is provided on the right side of the first screw 5.

[0029] During operation, when the transmission plate 902 enters the clamping groove 10, the transmission plate 902 contacts the inner wall of the clamping groove 10, which can prevent the second knob 8 from sliding back to the left.

[0030] Furthermore, two guide plates 11 are fixedly connected to the outer side of the second screw 6, and two guide grooves 12 are opened on the inner side of the second knob 8. The guide plates 11 are in clearance fit with the wire groove.

[0031] During operation, the guide plate 11 and the guide groove 12 can restrict the movement of the second knob 8, making the second knob 8 more stable when it moves to the outside of the second screw 6.

[0032] Furthermore, the inner side of the second screw 6 is slidably connected to the first extension plate 13, and the left side of the first extension plate 13 is fixedly connected to the second extension plate 14. The top and bottom of the second extension plate 14 are in contact with the first toothed plate 901.

[0033] Furthermore, the top and bottom of the second extension plate 14 are fixedly connected to a limiting plate 15, one end of which extends through the interior of the first toothed plate 901.

[0034] During operation, the limiting plate 15 enters the first toothed plate 901 and restricts the first toothed plate 901, making the first toothed plate 901 more stable when moving up and down, and less prone to shaking or displacement during movement.

[0035] Working principle: In the initial state, the first knob 7 and the second knob 8 are in contact. At this time, the transmission plate 902 inside the second knob 8 will enter the opening on the right side of the first screw 5, so that the first knob 7 and the second knob 8 are connected. When the first knob 7 or the second knob 8 is rotated, the first screw 5 and the second screw 6 will rotate at the same time, so that the two fixed bases 3 can move in the same direction or in opposite directions.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
