[0041] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] A cross-flow fan is a special fan, usually in the shape of a tower column or a large cylinder. The wind blown out is concentrated and columnar, so it can be used in combination to form a relay air flow transmission. It is generally used in the field of air conditioning. One end is connected to the fan output end, and the other end is usually connected to a connecting block by a bearing, and the connecting block is fixed inside the air conditioner by bolts. However, the connection method between the cross-flow fan blade and the air conditioner used in the prior art is cumbersome to disassemble when the cross-flow fan blade is damaged and needs to be replaced or cleaned.

[0043] In order to solve the above technical problems, in at least one embodiment, an injection molded crossflow fan blade fixing device is provided, comprising: a fixing block 2, on which a through slot 26 is formed; an automatic snap-fit ​​mechanism is arranged in the through slot 26; and a connecting rod 10, connected to one end of the crossflow fan blade, on which a connecting mechanism is arranged; wherein the connecting mechanism is suitable for being inserted into the through slot and cooperating with the snap-fit ​​mechanism, so that the connecting rod 10 is connected to the fixing block 2, and thus the crossflow fan blade 1 is connected to the fixing block 2;

[0044] By providing a connecting mechanism and an automatic snap-fit ​​mechanism, before the cross-flow fan blades are connected to the air conditioner, the fixing block is fixed to the air conditioner, and then the connecting mechanism is connected to the automatic snap-fit ​​mechanism, so that the cross-flow fan blades and the air conditioner can be connected. When the cross-flow fan blades need to be removed, it is only necessary to push the cross-flow fan blades to make the automatic snap-fit ​​mechanism disengage from the connecting mechanism. The structure is simple, and disassembling and installing the cross-flow fan blades saves time and effort.

[0045] In some embodiments, before connecting the crossflow fan blade 1 to the inside of the air conditioner, the fixing block 2 is preferably fixed to the inner wall of the air conditioner. The connection method between the fixing block 2 and the air conditioner is a prior art and will not be repeated here. Subsequently, when installing the crossflow fan blade 1, one end of it is connected to the motor and a connecting rod 10 is fixed to the other end. The connecting rod 10 is inserted into the through groove 26 opened on the fixing block 2 to connect the connecting rod 10 to the fixing block 2.

[0046] In some embodiments, a connecting piece 11 is fixed at the end of the connecting rod 10, and the cross section of the end of the connecting piece 11 facing the fixing block 2 is trapezoidal. As the connecting rod 10 inserts the connecting piece 11 into the through groove 26, as shown in FIG. Figure 2As shown, the inclined surface of the connecting member 11 first contacts the block 24. In order to make the block 24 and the inclined surface of the connecting member 11 fit better, an inclined surface is opened at the end of the block 24 so that the inclined surface of the block 24 contacts the inclined surface of the connecting member 11. Preferably, two blocks 24 are provided. At this time, the connecting member 11 pushes the two blocks 24 to slide in the square groove 23 and move away from each other, driving the slide bar 21 connected to each block 24 to slide in the cylindrical groove 22. At this time, the spring 25 is compressed. When the connecting member 11 passes through the two blocks 24, the spring 25 is reset and the two blocks 24 are pushed out, so that the block 24 is located between the connecting member 11 and the auxiliary split member 13. At this time, the crossflow fan blade 1 is connected to the fixed block 2, that is, at this time, the crossflow fan blade 1 is connected to the air conditioner.

[0047] In some embodiments, when the crossflow fan blade 1 needs to be disassembled, the operator manually grasps and pushes the crossflow fan blade 1, so that the crossflow fan blade 1 moves toward the fixing block 2. At this time, the block 24 moves toward the connecting plate 16 on the crossflow fan blade 1 until it contacts the auxiliary split piece 13. The two blocks 24 squeeze the auxiliary split piece 3 and move away from each other again until the auxiliary split piece 13 completely passes through the two blocks 24. Then, the operator pulls the crossflow fan blade 1 away from the fixing block 2. At this time, the two blocks 24 contact the auxiliary split piece 13 again. Figure 2 It can be known that the cross-section of one end of the auxiliary split piece 13 facing the connecting plate 16 is trapezoidal, that is, at this time, the block 24 pushes the auxiliary split piece 13 to slide on the connecting rod 10 until the annular piece 14 is inserted into the annular hollow part 12. As the cross-flow fan blade 1 continues to move, the block 24 slides along the surface of the auxiliary split piece 13 until it slides to the outer wall of the connecting piece 11 and disengages from the connecting piece 11, so that the cross-flow fan blade 1 can be disassembled. The structure is simple and the installation and disassembly are convenient.

[0048] On the other hand, an injection molded crossflow fan blade is provided, which is connected to an air conditioner using the above-mentioned fixing device.

[0049] To summarize, by providing a connecting mechanism and an automatic snap-fit ​​mechanism, before the cross-flow fan blades are connected to the air conditioner, the fixing block is fixed to the air conditioner, and then the connecting mechanism is connected to the automatic snap-fit ​​mechanism, so that the cross-flow fan blades can be connected to the air conditioner. When the cross-flow fan blades need to be removed, it is only necessary to push the cross-flow fan blades so that the automatic snap-fit ​​mechanism is disengaged from the connecting mechanism. The structure is simple, and the removal and installation of the cross-flow fan blades saves time and effort.
