[0002] HVAC engineering includes heating, ventilation and air conditioning. Heating is to supply load to the building as needed to ensure that the indoor temperature is continuously higher than the external environment as required by people. Ventilation is the process of supplying air into or exhausting air from the room. Air conditioning is a building environment control system used to adjust the temperature, humidity, cleanliness and air flow rate in a room or space and provide sufficient fresh air.

[0003] At present, the installation of HVAC pipes is generally fixed on the ceiling by means of staples or half-moon clamps, wherein the clamps also need to be fixed with nails to make the installation of the HVAC pipes more secure. However, when maintenance is required later, the nails need to be removed by tools to disassemble the HVAC pipes. In addition, it is difficult to remove the nails after they are nailed in, which increases the maintenance workload. At the same time, after maintenance, it is necessary to find a place on the ceiling to fix the staples or half-moon clamps again, leaving many nail holes on the ceiling, which not only causes damage but also affects the appearance. Therefore, a HVAC pipe installation structure for HVAC engineering is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 In this embodiment, a HVAC pipe installation structure for HVAC engineering includes a ceiling 1, characterized in that: four screw rods 2 in a group are fixedly installed on the ceiling 1, a fixing assembly 3 is installed on the four screw rods 2, nuts 4 are threadedly connected on the four screw rods 2, and the fixing assembly 3 is fixed on the four screw rods 2 through four nuts 4;

[0025] Two symmetrically arranged clamping plates 5 are movably mounted on the upper surface of the fixing component 3 , and transverse arc grooves are opened and closed on the opposite surfaces of the two clamping plates 5 . An adjusting plate 6 and a toggle rod 7 are also mounted on the bottom of the fixing component 3 .

[0026] In this embodiment, when the HVAC pipe needs to be maintained, first rotate the nut 4 to separate it from the screw 2, then remove the fixing assembly 3 from the four screws 2 fixedly installed on the ceiling 1, and then just push the toggle rod 7 to move to the left, so that the limit plate 309 moves to the left synchronously and disengages from the tooth groove of the gear 308, and then rotate the adjusting disk 6 to drive the gear 308 to rotate clockwise, thereby controlling the two clamping plates 5 to move backwards to loosen the clamped HVAC pipe, thereby achieving the purpose of quickly disassembling the HVAC pipe.

[0027] It should be noted that the length of the screw rod 2 is greater than the distance between the top of the clamping plate 5 and the bottom of the base 301, so as to avoid the situation where the fixing component 3 cannot pass through the mounting hole 302 of the base 301 after clamping the HVAC pipe due to the screw rod 2 being too short, thereby preventing the fixing component 3 from being installed on the screw rod 2.

[0028] See also Figure 5 In order to avoid damaging the ceiling and facilitate disassembly, the four corners of the base 301 in this embodiment are provided with mounting holes 302 that are compatible with the screw rod 2 and are slidably connected thereto.

[0029] In this embodiment, the screw rods 2 are fixedly installed on the ceiling 1 in groups of four, and the base 301 is fixed by the nut 4 threadedly connected thereto. When the HVAC pipe is maintained, the fixing component 3 can be removed from the screw rod 2 by simply rotating the nut 4. After the maintenance, the screw rod 2 on the ceiling 1 can be reused to fix the fixing component 3, and there is no need to find a new place to install the screw 2, thereby avoiding damage to the ceiling 1, reducing the difficulty of maintenance and installation, and improving maintenance efficiency.

[0030] See also Figure 1-4In order to quickly install and fix the HVAC pipe, the fixing component 3 in this embodiment includes a base 301, a mounting groove 303 is opened inside the base 301, two sliding frames 304 are slidably connected in the mounting groove 303, two sliding blocks 305 are fixedly connected to the upper surfaces of the opposite sides of the two sliding frames 304, and a clamping plate 5 is fixedly installed on the top of the two sliding blocks 305 on the same side. Four sliding holes 306 are opened on the upper surface of the base 301 and communicate with the mounting groove 303. The four sliding blocks 305 are respectively connected to the corresponding sliding holes 306 and slidably connected thereto. Two arc blocks 307 are fixedly installed at the center of the inner bottom wall of the base 301 and are located in the middle of the two sliding frames 304. A gear 308 is arranged in the middle of the two arc blocks 307. The two sliding frames 304 are arranged to slide in opposite directions, and a gear is opened on the inner wall opposite to one side. The groove is meshed with the gear 308. The bottom of the base 301 is rotatably connected with an adjusting disk 6. The rotating shaft of the adjusting disk 6 is fixedly connected to the center of the lower end surface of the gear 308. A groove is opened in the middle of the arc block 307 on one side and is slidably connected with a limit plate 309. A sliding rod 310 and a toggle rod 7 are fixedly installed on the side of the limit plate 309 away from the gear 308. A spring 312 is movably mounted on the outer wall of the sliding rod 310. The thickness of the limit plate 309 is matched with the tooth groove of the gear 308. A fixing plate 311 is fixedly connected to the inner bottom wall of the base 301. A through hole is opened on the fixing plate 311 for the sliding rod 310 to be retracted and slidably connected to it. The bottom groove of the fixing plate 311 is slidably connected to the toggle rod 7. A reset groove 313 is opened on the lower surface of the base 301. The toggle rod 7 is L-shaped and extends from the reset groove 313 to the bottom of the base 301.

[0031] In this embodiment, the adjusting disk 6 is rotated to drive the gear 308 fixedly connected thereto to rotate. Under the action of meshing, the gear 308 rotates to control the movement of the two sliding frames 304, thereby causing the clamping plates 5 fixedly installed on the two sliding frames 304 to move in the same direction to fix the HVAC pipe placed in the middle, thereby achieving quick removal of the HVAC pipe.

[0032] It should be noted that a slope is provided on the side of the limit plate 309 close to the gear 308. When the gear 308 rotates counterclockwise, its tooth block pushes the limit plate 309 from the slope in turn to retract. At the same time, the limit plate 309 is supported by the set spring 312, so that the limit plate 309 retracts and extends along with the interval between the tooth block and the tooth groove, thereby clamping the main gear 308 to limit it, preventing the gear 308 from loosening after the two clamping plates 5 clamp the HVAC pipe, thereby causing the HVAC pipe to fall off due to loose clamping.

[0033] It can be understood that the function of the toggle rod 7 is to push the toggle rod 7 to shrink the limit plate 309 when maintaining the HVAC pipe, thereby canceling the limit on the gear 308, allowing the adjustment disk 6 to drive the gear 308 to rotate, thereby allowing the two clamping plates 5 to loosen the fixed HVAC pipe to achieve the purpose of quick removal.

[0034] The working principle of the above embodiment is:

[0035] (1) First, turn the nuts 4 on the four screw rods 2 to separate them, and then remove the fixing assembly 3 from the four screw rods 2.

[0036] (2) After the fixing assembly 3 is removed, the toggle lever 7 is first pushed to move to the left, so that the limit plate 309 fixedly connected thereto moves to the left synchronously. At this time, the limit plate 309 no longer blocks the tooth block from the tooth groove on the gear 308. Then, the adjusting disk 6 is turned to make it rotate clockwise, thereby driving the gear 308 fixedly connected to its rotating shaft to rotate. Under the action of meshing, the two sliding frames 304 are controlled to slide in the installation groove 303, and the two clamping plates 5 fixedly installed above them are driven to move synchronously in the opposite direction, so that the two clamping plates 5 loosen the HVAC pipe clamped in the middle, so as to achieve the purpose of quickly removing the HVAC pipe, which is convenient for maintenance personnel to disassemble and improves the maintenance work efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
