As shown in fig. 1, 2 and 4, a through hole 13 is formed in a side wall of the first end of the first connecting member 10, and a long side direction of the through hole 13 extends along an axial direction of the first connecting member 10. Set up like this and make the back-off face that produces because of axial demolding can follow through-hole side demolding to avoid causing the interior circumference size reduction because of the step that the die joint produced, influence the problem of assembly. Preferably, the through hole 13 is plural. A plurality of through holes 13 are provided at intervals in the circumferential direction of the first connecting member 10.

As shown in fig. 1 and 3, the outer surfaces of the plurality of second protrusions 21 are each provided with a protrusion 30. The protrusions 30 are plural, and the plural protrusions 30 are provided at intervals along the circumferential direction of the second bump 21 to form an annular protrusion. The arrangement can effectively avoid the influence of the step generated by the parting line on the size of the matching surface. Meanwhile, the contact form of the protrusion 30 is changed from surface contact to line contact, and the clearance fit is changed into interference fit, so that the first connecting piece and the second connecting piece are matched more tightly, and the fan blade running shake caused by the assembly clearance is avoided. The first connecting piece and the second connecting piece are connected with the motor output shaft and can be called as motor shaft sleeves, and the first connecting piece and the second connecting piece are connected with the fan blade shaft and can be called as fan blade shaft sleeves.

The connecting assembly in the above embodiment may also be used in the technical field of air conditioner equipment, that is, according to another aspect of the present invention, there is provided an air conditioner, including the connecting assembly in the above embodiment.

Specifically, in the prior art, the existing fan blade and motor shaft connecting mechanism can solve the problem of quick disassembly, but due to the limitation of an assembly process, clearance fit needs to be adopted, and the smaller the fit clearance, the higher the requirement on a machining process is, so that the cost is increased. Due to the assembly clearance, the fan blade can vibrate in the operation process.

To the defect problem that above technique brought, this application provides a new-type transmission structure, increases the arch on original structural basis, and the quick separation of realization fan blade and motor that can be simple can guarantee driven stability simultaneously, reduces fan blade running noise. Meanwhile, the optimization of the structure reduces the requirement on the processing technology, thereby reducing the cost.

Aiming at the defect problems brought by the technology, the structure realizes the conical surface matching through the connecting column and the first lug, improves the coaxiality of the fan blade and the motor, and ensures the stability of the operation of the fan blade. The structure can be used for easily disassembling the air duct component, ensuring stable operation and reducing the running noise of the fan blade. Meanwhile, the safety of operators is improved without disassembling the charged part. The connecting assembly adopts a line-surface matching structure, and the bulges are added on the basis of the original matching surface, so that the matching clearance is smaller, and the fan blade runs more stably. The fan blade and the motor are quickly connected and separated, so that the fan blade and the motor can be easily connected and separated, and the whole air duct component can be detached and cleaned.

In this embodiment, a schematic structural diagram of the motor shaft sleeve is shown in fig. 3, a schematic structural diagram of the fan blade shaft sleeve is shown in fig. 2, and a connection structure between the fan blade and the shaft sleeve may be adopted on the side of the fan blade, or the fan blade and the shaft sleeve may be integrally formed. The fan blade adopts detachable construction with the motor shaft cooperation: the fan blade and the motor are matched with the spiral surface of the fan blade by the motor shaft sleeve. The fan blades are arranged on the bottom shell through the structure to form an air duct component, the motor component is arranged on the base, and the fan blades are not directly connected with the motor component.

The motor shaft sleeve moving surface and the wind blade end surface shaft sleeve are designed into a spiral structure, so that when the moving part operates, an axial force exists on the matching surface of the wind blade shaft sleeve and the wind blade, and the wind blade can not be separated from the motor shaft sleeve and can firmly operate due to the axial force. The specific operation is as follows: because of the existence of the spiral structure, when the distance between the motor shaft sleeve and the fan blade end surface shaft sleeve is close to a certain distance, the motor is started to rotate, the motor shaft sleeve and the fan blade end surface shaft sleeve are influenced by the spiral structure to be closer and closer until the motor shaft sleeve and the fan blade end surface shaft sleeve are meshed in place, the structure is not required to be influenced by the corresponding positions of the motor and the fan blade end surface shaft sleeve, and 360-degree complete. Meanwhile, the motor rotates forwards all the time, so that the matching structure of the motor and the motor is tighter and tighter. When the air duct component needs to be cleaned, the fan blade is only required to be reversed and slightly pushed in the direction away from the motor, and then the fan blade and the motor can be separated. Thereby realized motor element and kept alone on the base, realized motor element and air duct system separation, avoided the hidden danger of human electric shock because of not electrified machine element when wasing the wind channel.

Preferably, the embodiment shown in the figures all have three helical structures, and other numbers of helical structures may be used to satisfy this installation. The fan blade and the fixed shaft sleeve can be integrally formed, and a structural form that the fan blade is connected with the shaft sleeve through screws and clamping positions can also be adopted. Meanwhile, the motor and the fixed shaft sleeve thereof can also adopt a structure form of fixing screws and clamping positions, and the motor and the shaft sleeve structure can adopt an integrated structure form, but the existing motor is mature, so the change is large, and the cost is high. The shaft sleeve component assembled by the fan blade and the shaft sleeve component assembled by the motor can be exchanged with each other, and the motor can drive the fan blade to rotate. The bulge of the motor shaft sleeve can also be arranged on the fan blade shaft sleeve, and the realization of the bulge can also adopt embedded steel balls or other movable designs.

In the embodiment shown in fig. 4, the protrusion structure may be eliminated to increase the fit clearance of the fit surface, and at the same time, a conical surface is added at one end of the motor shaft sleeve to fit with the fan shaft sleeve through the conical surface. Axial tension towards the motor end can be generated in the operation process of the fan blades, the radial tight fit of the motor shaft sleeve and the fan blade shaft sleeve is ensured through the conical surface matching, and the coaxiality of the motor shaft and the fan blade shaft is improved.
