Technical Field

[0001] This utility model relates to the field of air conditioning duct protection technology, and in particular to a protective device for grinding air conditioning ducts. Background Technology

[0002] Air conditioning piping is a complex and crucial system component, with different definitions and functions depending on the application scenario. Automotive air conditioning piping refers to the piping system within a car's air conditioning system, responsible for connecting various components to ensure orderly operation. These components typically include aluminum pipes, connectors, air conditioning hoses, air conditioning corrugated pipes, aluminum sleeves, filling ports, sight glasses, pressure switches, O-rings, and plastic caps. Household air conditioning piping mainly refers to the pipes connecting the indoor and outdoor units of the air conditioner, including copper pipes, used to conduct refrigerant and achieve the cooling or heating functions of the air conditioner. It also includes pipes for draining condensate. Both automotive and household air conditioning piping require certain high-temperature and high-pressure resistance to ensure the system can operate normally under high-temperature and high-pressure environments. Protective devices for air conditioning piping grinding are specialized devices designed to address the potential hazards and contamination that may occur during the grinding process. The main purpose of these devices is to protect operators from the splashes, noise, and vibration generated during grinding, while ensuring efficient and safe grinding operations.

[0003] To this end, Chinese patent application number CN216371706U discloses a protective device for grinding neodymium iron boron magnets, including a fixed protective plate, a worktable, a support plate, a fixed base, and a lifting assembly. The support plate is fixedly mounted on the upper side of the fixed base, the worktable is fixedly mounted on the support plate, the fixed protective plate is fixedly mounted on the worktable, and the lifting assembly is mounted on the fixed base. The lifting assembly includes a drive motor, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a rotating rod, a screw, a threaded block, and a movable protective plate. The drive motor is fixedly mounted on the fixed base, the rotating rod is rotatably mounted on the support plate, the output end of the drive motor is fixedly connected to one end of the rotating rod, and the screw is rotatably mounted on the worktable. This utility model belongs to the field of neodymium iron boron magnet processing technology, specifically a convenient and highly safe protective device for grinding neodymium iron boron magnets.

[0004] While current protective devices for grinding air conditioning pipes generally meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of protective devices used for grinding air conditioning pipes is that they cannot protect the eyes and ears of operators. During the grinding process, a large number of sparks, debris and noise are generated. Sparks and debris will fly everywhere and are very likely to fly into the eyes of operators, causing great harm to them. Prolonged exposure to the noise environment will also damage the ears of operators and cause hearing damage.

[0006] 2. The problem of the protective device for grinding air conditioning pipes is that it is difficult to collect the grinding debris. When the operator grinds the air conditioning pipes, some burrs and uneven parts will be cut and ground flat, which will produce a large number of fine metal fragments and dust. This is difficult to clean and will also block the gaps of the machine, affecting the service life of the machine and affecting the health of the operator. Utility Model Content

[0007] The purpose of this utility model is to provide a protective device for grinding air conditioning pipes, in order to solve the defects of existing protective devices for grinding air conditioning pipes, which are difficult to protect the eyes and ears of operators and difficult to collect grinding debris.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective device for grinding air conditioning pipes, including support legs;

[0009] A support frame is fixed to the top of the support leg, and an operating table is fixed to the top of the support frame.

[0010] The support frame is equipped with a lifting mechanism, and a protective structure is installed at one end of the top of the operating table;

[0011] Both sides of the top of the operating table are equipped with fixing plates, and the top of the fixing plates is through a fixing screw. A dust collection mechanism is installed at one end of the operating table.

[0012] In use, first turn on the servo motor to drive the rotating shaft and the drive gear to rotate. Through the meshing transmission of the driven gear, the lifting rod is driven to rotate. The rotation of the lifting rod can drive the moving block and the lifting plate to rise and fall, thereby adjusting the height of the operating table. Before grinding, place the air conditioning pipe in the fixed plate. The fixed plate at one end can be moved and the pipe is fixed by tightening the fixing screw. Before grinding, turn on the fan. The air can suck the grinding debris to the baffle and fall into the dust collection box. During grinding, the operator can rotate the adjustment rod to adjust the position of the protective plate and take out the earplugs from the storage box to protect the ears. The vent holes and vent grooves on the protective plate can ensure that the operator will not inhale the debris.

[0013] Furthermore, the lifting mechanism includes a servo motor, a rotating shaft, a driving gear, a driven gear, a lifting rod, a moving block, a lifting plate, and an auxiliary rod. The servo motor is installed at the bottom end of one side of the support frame, and a rotating shaft is installed at the output end of the servo motor. Driving gears are fixed on the outer sides of both sides of the rotating shaft. The top of the driving gear is meshed with a driven gear, and a lifting rod is fixed to the top of the driven gear. A moving block is threaded to the outer side of the lifting rod, and a lifting plate is fixed on one side of the moving block. The auxiliary rod is fixed at both ends of the bottom of the operating table, and the height of the operating table can be adjusted according to the needs of the operator.

[0014] Furthermore, both the driving gear and the driven gear are provided with retaining teeth on their outer sides, and the driving gear and the driven gear are meshed together, so that the servo motor can drive the shaft and the driving gear to rotate at the same time.

[0015] Furthermore, the protective structure includes a mounting block, a storage box, an anti-loss cable, earplugs, an adjusting rod, a connecting block, a protective plate, ventilation holes, and ventilation slots. The mounting block is fixed to both sides of the top of the operating table. A storage box is installed on the top of the mounting block. An anti-loss cable is glued to the bottom of the storage box. An earplug is glued to one end of the anti-loss cable. An adjusting rod runs through the interior of the mounting block. A connecting block is threaded to the outside of the adjusting rod. A protective plate is fixed to the top of the connecting block. Ventilation holes are provided inside the protective plate. A ventilation slot is integrally formed at one end of the protective plate, which can protect the operator's eyes and ears.

[0016] Furthermore, the outer side wall of the adjusting rod is uniformly provided with external threads, and the inner side wall of the connecting block is uniformly provided with internal threads that cooperate with the external threads. The adjusting rod and the connecting block are threadedly connected, and the rotation of the threaded rod can drive the connecting block to move, so that the position of the protective plate can be adjusted according to the needs of the operator.

[0017] Furthermore, the dust collection mechanism includes a baffle, a fan, an air duct, a filter, a dust suction hole, a material discharge port, and a dust collection box. The baffle is fixed to one end of the top of the operating table, the fan is installed at one end of the operating table, an air duct is installed at one end of the fan, and dust suction holes are evenly installed at one end of the air duct. A filter is installed inside the dust suction hole, the material discharge port is opened inside one end of the operating table, and a dust collection box is provided at the bottom of the material discharge port, which can automatically clean up debris in the air and on the operating table.

[0018] Furthermore, both ends of the top of the dust collection box are equipped with sliders, and one end of the bottom of the operating table is equipped with a sliding groove. The dust collection box and the operating table are slidably connected, which facilitates the centralized cleaning of debris after grinding.

[0019] This utility model provides a protective device for grinding air conditioning pipes. Its advantages are as follows: By installing an installation block at the top of the workbench and rotating the adjusting rod passing through the installation block, the position of the protective plate can be adjusted according to the operator's needs. The protective plate is made of transparent acrylic material, protecting the operator's eyes without obstructing observation. Ventilation holes and grooves are provided on the protective plate to prevent the operator from inhaling debris. A storage box is fixed to the top of the installation block, containing earplugs connected via an anti-loss cable. Wearing the earplugs during grinding protects the operator's ears and prevents hearing damage. The anti-loss cable prevents the earplugs from being lost. Thus, the protective device for grinding air conditioning pipes protects the operator's eyes and ears.

[0020] By installing a baffle and a fan at one end of the operating table, turning on the fan generates suction, which is transmitted through the air duct and dust suction hole to attract the debris generated during the grinding of the air conditioning ducts. The debris in the air and on the operating table is sucked towards the baffle. The dust suction hole is equipped with a filter to prevent debris from entering the air duct and dust suction hole, thus avoiding damage to the fan. The collected debris will fall into the dust collection box under the action of gravity through the discharge port. The dust collection box can be removed from the bottom of the operating table by sliding, making it easy to collect and clean the debris after grinding. This achieves the purpose of the protective device for grinding air conditioning ducts, which can collect the grinding debris. Attached Figure Description
