Description

Technical Field

[0002] Fan coil units are one of the terminal devices in an air conditioning system, consisting of a small fan, motor, and coil. When refrigerant or heat transfer medium flows through the coil, it exchanges heat with the outside air, cooling, dehumidifying, or heating the air to regulate indoor air parameters. The surface cooler is a crucial component of the fan coil unit, mainly consisting of metal pipes and several fins. The metal pipes are embedded within the fins, which facilitate heat exchange. During the production of fan coil units, multiple processes require different equipment, necessitating the handling of the surface cooler between these machines. Currently, this is typically done by hand, with workers grasping the outer edges of the fins. During handling, the fins can be damaged by external forces, causing them to tilt and affecting the heat exchange efficiency and appearance of the surface cooler. Utility Model Content

[0025] Please see Figures 1 to 6This utility model provides a handling fixture for a fan coil unit surface cooler, comprising: two clamping plates 100, a rack assembly 200, a drive assembly 300, and a handle assembly 400. Each of the two clamping plates 100 has an anti-slip pad 110 on its opposing surfaces, the anti-slip pad 110 being arranged along the extending direction of the clamping plates 100. A pressure plate 120 is mounted on each of the two clamping plates 100 on their opposite surfaces. The rack assembly 200 includes a first rack 210, a second rack 220, and two connecting plates 230. The two connecting plates 230 are respectively arranged along the top surfaces of the two clamping plates 100 and are fixedly connected to the two pressure plates 120. One end of the first rack 210 and the second rack 220 are respectively vertically fixedly connected to the middle of the opposing surfaces of the two connecting plates 230. The drive assembly 300 includes a drive box 310, in which the first rack 210 and the second rack 220 pass through. A first gear 311 is rotatably mounted inside the drive box 310, and the first gear 311 meshes with the first rack 210 and the second rack 220 respectively. A gearbox 320 is provided on the top of the drive box 310, and a gear assembly 330 is provided inside the gearbox 320. The gear assembly 330 is connected to the first gear 311 in a transmission manner. A locking assembly 340 is provided on the outside of the gearbox 320, and the locking assembly 340 cooperates with the gear assembly 330. The locking assembly 340 is used to control the locking or rotation of the gear assembly 330. The handle assembly 400 includes a handle frame 410 and a handle 420. The handle frame 410 is mounted on the top of the gearbox 320, and the handle 420 is slidably mounted inside the handle frame 410.
