Description

Technical Field

[0001] The utility model relates to the field of coil flexible connectors, in particular to a fan coil flexible connector. Background Art

[0002] The fan coil unit flexible joint is composed of a hose, a connecting pipe and a connector. It is a device used to connect fan coil units and is more common in daily life.

[0003] The prior art, such as the utility model with publication number CN206875005U, discloses a fan coil flexible connection mechanism. The patent adopts a bellows, a double-headed tooth joint, a silicone gasket and a loose nut. The double-headed tooth joint is installed at both ends of the bellows; the bellows end is integrally formed with an extension portion, the extension portion includes a front straight edge and a rear straight edge, a bellows clamp is provided between the front straight edge and the rear straight edge, the loose nut is sleeved on the rear straight edge, and a silicone gasket is sleeved on the front straight edge. The double-headed tooth joint is pressed on the silicone gasket and the loose nut is screwed on the double-headed tooth joint, which is more convenient to install in the central air-conditioning system, so that the connection between the host and the pipeline is added with a flexible connection, reducing the transmission of vibration, and at the same time, it can better protect the fan coil flexible connection from colliding with the loose nut and being damaged during actuation. The silicone gasket is not easy to fall off during installation, which solves the problem that the fan coil flexible connection interface is sealed by a double-headed tooth joint and a loose nut tightening a silicone gasket. During installation, the double-threaded joint must be removed to connect to the pipe joint. Once the double-threaded joint is removed, the silicone gasket will fall to the ground without support, causing significant installation inconvenience. The first two crests of the fan coil unit's bellows can easily come into contact with the loose nuts during operation. Since the bellows are extruded from thin-walled stainless steel, prolonged contact with the loose nuts can damage the bellows.

[0004] The inventor found in his daily work that in the process of using the hose, the existing technology uses nuts to connect the hose to other pipes, which means that multiple nuts need to be turned multiple times to fix the hose when connecting it. Therefore, it is time-consuming to install or remove the hose. Moreover, if the nut is misplaced when installing the hose, it is very easy to get stuck, and the nut is difficult to tighten by manpower and requires the use of tools.

[0005] Therefore, it is necessary to provide a new fan coil flexible connector to solve the above technical problems. Utility Model Content

The end of the slide 409 away from the fixed plate 403 is fixedly connected to the hook plate 410. A number of clamping blocks 411 are fixedly connected to the side of the connector 3 close to the hook plate 410. The hook plate 410 is clamped with the clamping block 411. When the connector 401 needs to be connected to the connector 3, the connector 401 is pulled to move, the connector 401 drives the limit block 402 to move, the limit block 402 drives the fixed plate 403 to move, the fixed plate 403 drives the insertion rod 404 and the slide 409 to move, the slide 409 drives the hook plate 410 to move, and then the fixed plate 403 is pulled to adjust the angle. After adjusting to the appropriate angle, the hook plate 410 is adjusted to move, and then the hook plate 410 is aligned with the After the block 411 is aligned and moved to the appropriate position, the slide 409 is pulled to move, and then the slide 409 drives the socket 406 to move.

Then, the insertion rod 404 is pulled to move, and the insertion rod 404 is aligned with the fixing plate 403 and the socket 406. Then, the insertion rod 404 is inserted into the socket 406 and fixed. The inner wall of the hook plate 410 is fixedly connected with an anti-slip cover 412, which is a rubber cover. The anti-slip cover 412 can increase the friction between the hook plate 410 and the block 411 to prevent the block 411 from slipping when connected to the hook plate 410. The arc surface of the insertion rod 404 is covered with a spring 405, and the two ends of the spring 405 are respectively fixedly connected to the insertion rod 404 and the fixing plate 403.

When the insertion rod 404 needs to be inserted for fixing, the insertion rod 404 is pulled to drive the spring 405 to stretch, and then the insertion rod 404 is aligned with the fixing plate 403 and the insertion hole 406. Then the insertion rod 404 is released and the spring 405 is contracted to drive the insertion rod 404 to be inserted for fixing. When the fixing plate 403 is pulled for adjustment, the fixing block drives the coil spring 408 to contract. After the adjustment is completed, the rebound force of the coil spring 408 can drive the fixing plate 403 to reset, and the sliding rod 413 can position the connector 401 to prevent the connector 401 from deviating when connected to the connector 3 and the connecting pipe 2, thereby improving the connection efficiency of the connector 401.
