[0025] As mentioned above, the prior art uses bolt locking to achieve the installation of the rotor. The space in the fresh air system is compact and the installation operation space is limited, which makes it inconvenient to tighten the bolts, which in turn causes low production efficiency, especially for mass production, which seriously hinders work efficiency. Therefore, there is an urgent need for a structure for quickly installing a rotor heat exchanger. The shaft of the rotor is inserted into the guide rail and slides along the guide rail, so that the middle hole at the end of the shaft is easily aligned with the plug-in part of the spring latch. The installation can be achieved by inserting the plug-in part into the middle hole. Compared with traditional bolt installation, it is quick to install; without increasing the operating space, it has the characteristics of quick installation, improves the efficiency of assembly production, and is suitable for mass production.

[0026] The following will introduce the application of the structure of the quick-install rotary heat exchanger provided by the present invention in the rotary wheel assembly process during the production of the fresh air system.

[0027] Please refer to Figure 1 and Figure 7 A structure for quickly installing a rotary heat exchanger comprises: a rotary bracket, which provides a mounting position for the rotary wheel; a spring latch, which is mounted on the rotary bracket, and has a plug-in portion, and the plug-in portion is movable; a guide rail, which is arranged on the rotary bracket, and the end of the shaft body of the rotary wheel is inserted into the guide rail, and the shaft body slides along the length direction of the guide rail to adjust the middle hole opened at the end of the shaft body to align with the plug-in portion.

[0028] Exemplarily, the plug-in portion includes a pin and a pull ring; one end of the pin is used to be inserted into the middle hole of the shaft body, and the other end is provided with an end hole; the pull ring passes through the end hole and is connected to the pin.

[0029] Exemplarily, the spring latch includes an externally threaded sleeve and a coil spring; the externally threaded sleeve is sleeved onto the column pin, and the column pin and the externally threaded sleeve are elastically connected via the coil spring.

[0030] Exemplarily, the pin is composed of two cylinders, the cylinder with a larger diameter on the pin cooperates with the inner wall of the external threaded sleeve, and one end of the cylinder with a smaller diameter on the pin cooperates with the hole body at one end of the external threaded sleeve. The coil spring is sleeved on the cylinder with a smaller diameter on the pin, and the coil spring is located in the external threaded sleeve.

[0031] Exemplarily, a nut sleeve is fixedly mounted on the rotating wheel bracket, and the nut sleeve is connected to the guide rail, and the external threaded sleeve of the spring latch is threadedly connected to the nut sleeve.

[0032] Exemplarily, one end of the guide rail is provided with a retaining edge for blocking the shaft body; the shaft body contacts the retaining edge, and the middle hole of the shaft body is aligned with the plug-in portion.

[0033] Exemplarily, the guide rail is fixed to the rotating wheel bracket by countersunk rivets.

[0034] Specifically, Figure 1 and Figure 7 As shown, the structure of a quick-installation rotary heat exchanger described in this scheme includes a rotary wheel 1, a rotary wheel bracket 2, a nut sleeve 3, a spring latch 4, a column pin 401, an end hole 4011, an external threaded sleeve 402, a coil spring 403, a pull ring 404, a countersunk rivet 5, a guide rail 6, a positioning rib 601, a shaft body 7, and a center hole 701.

[0035] The shaft body 7 is fixedly installed on the runner 1, and the two form an integral body. The nut sleeve 3 is riveted to the runner bracket 2, and then the guide rail 6 is riveted to the runner bracket 2 with a countersunk rivet 5, the coil spring 403 is sleeved on the small diameter cylinder of the pin 401, and then the external threaded sleeve 402 is sleeved on the pin 401, the pull ring 404 is inserted into the end hole 4011 of the pin 401 exposed from the external threaded sleeve 402, and then the external threaded sleeve 402 is screwed into the nut sleeve 3.

[0036] Usage and steps:

[0037] 1) Pull the pull ring 404, the pull ring 404 drives the pin 401 to move along the length direction of the external threaded sleeve 402, so that the end of the pin 401 away from the pull ring 404 is received into the external threaded sleeve 402, and at the same time, the pin 401 compresses the coil spring 403, causing the coil spring 403 to produce compression deformation;

[0038] 2) Insert the end of the shaft body 7 on the rotating wheel 1 into the guide rail 6, and slide the end of the shaft body 7 along the guide rail 6 until the shaft body 7 contacts the in-position retaining edge 601, and the middle hole of the shaft body 7 is aligned with the pin 401;

[0039] 3) Loosen the pull ring 404, and push the pin 401 to move outward from the external threaded sleeve 402 through the elastic force of the coil spring 403, so that the end of the pin 401 is inserted into the middle hole to complete the installation.

[0040] In the prior art, bolt locking is used to achieve the installation of the rotor. The space inside the fresh air system is compact and the installation operation space is limited, which makes it inconvenient to tighten the bolts, thereby causing low production efficiency. Compared with the prior art, the technical solution uses a specific structure for quickly installing the rotor heat exchanger to insert the shaft of the rotor into the guide rail and slide along the guide rail, so that the middle hole at the end of the shaft is easily aligned with the plug-in part of the spring latch. The installation can be achieved by inserting the plug-in part into the middle hole. Compared with traditional bolt installation, it is quick to install. It has the characteristics of fast installation without increasing the operating space, improves the efficiency of assembly production, and is suitable for mass production.
