Technical Field

[0001] The utility model relates to the technical field of HVAC facility installation, in particular to a general clamp for building HVAC. Background Art

[0002] The main functions of HVAC include: heating, ventilation and air conditioning. The comprehensive abbreviation of these three functions is HVAC. HVAC is a household central air-conditioning. Central air-conditioning is divided into water system and Freon system. The general split Freon air-conditioning in the home can only solve the heating and cooling problems, but cannot solve the air treatment process. The thickness and specifications of HVAC pipes can be changed according to requirements. Usually when connecting, the two ends of the air duct are always connected to the accessories. Under normal circumstances, there are no grooves at both ends of the HVAC pipe and they are equipped with sealing rings. The application range of HVAC pipes is very wide, including purification system return air ducts, central air-conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, mining rubberized cloth air ducts, etc.

[0003] However, when welding existing HVAC pipes, clamps are needed to ensure the accuracy of the HVAC pipes during installation. However, since the surface of the HVAC pipes is relatively smooth, general clamps are prone to cause the pipes to slip during use, resulting in pipe damage and increasing the work cost of HVAC installation. Therefore, a new type of universal clamp for building heating is needed. Utility Model Content

[0006] Preferably, four mounting plates are fastened to one side of the top wall of the working box, and a clamping box is fastened to one side of the surface wall of the slide plate.

[0007] Preferably, a mounting groove is provided on one side of the inner wall of the clamping box, and a cylinder is installed on one side of the inner wall of the mounting groove.

[0008] Preferably, the output end of the cylinder is fastened with a second connecting plate, and a second movable groove is provided on one side of the surface wall of the clamping box.

[0009] Preferably, a movable clamping plate is fastened to one side of the surface wall of the second connecting plate, and a third guide rail is installed on one side of the top wall of the clamping box.

[0010] Preferably, the third guide rail and the movable clamp are slidably connected, and a first friction pad is fastened to one side of the surface wall of the movable clamp.

[0011] Preferably, a fixing clamping plate is fastened to one side of the bottom wall of the clamping box, and a second friction pad is fastened to one side of the surface wall of the fixing clamping plate.
