Embodiment
Joint 1(is hereinafter to be referred as middle joint 1 in the axial-flow fan of the present utility model) structure is as shown in Figure 1 and Figure 2, mainly comprise blade 2, end cap 3, wherein, have groove (not indicating among the figure) on the described end cap 3, described blade 2 is installed on the groove, particularly, be provided with at least 2 locating buttons 4 on the described end cap 3, preferably, the quantity of described locating button 4 is 3, two upper and lower parts that are separately positioned on end cap 3 wherein, and another one is arranged on the medium position near end cap 3.Further, described middle joint 1 also comprises boss stiffening rib 5, wherein, the quantity of described boss stiffening rib 5 is also decided as required, preferably, and in the present embodiment, described boss stiffening rib 5 is 1, described boss stiffening rib 5 is arranged on the described end cap 3, and preferably, described boss stiffening rib 5 is arranged on the upper position of described end cap 3.Need to prove that described middle joint 1 is provided with two end caps 3, wherein said end cap 3 corresponding settings are respectively left end cap 3, right end cap 3.
A plurality of middle joints 1 connect and compose the impeller of fan vertically, and the axial centre of impeller is provided with turning axle 7(and sees Fig. 3).Behind a plurality of middle joint 1 integrated positionings, it is welding fabrication, wherein the mode of welding has multiplely, this is not restricted, as preferably herein, described a plurality of middle joint 1 is with the ultrasonic welding moulding, described locating button 4 in each on the joint 1 fastens mutually with the locating button 4 of adjacent middle joint 1, a plurality of middle joints 1 can be located fast, and then use the ultrasonic welding moulding, improve manufacturing efficiency, also can prevent to a certain extent in addition middle joint 1 distortion.Because joint is provided with boss stiffening rib 5 in each, when a plurality of middle joint 1 combination, can prevent to a certain extent middle joint 1 distortion, strengthen combined strength, strengthen the protection to falling.
For the ease of understanding, the below is combined as the detailed process of a plurality of middle joints 1 combinations of example explanation with joint 1 in two:
When saving 1 amalgamation in two, in one the locating button 4 of the left end cap 3 of joint on 1 with another in locating button 4 overlap joints on the right end cap 3 of joint 1, the boss stiffening rib 5 of adjacent middle joint 1 bumps and connects, then respectively in two between one group of locating button 4 of joint 1 correspondence, adopt ultrasonic welding between one group of boss stiffening rib 5 of joint 1 correspondence in two.When joint in two 1 connects, by the leading role of boss stiffening rib 5 and locating button 4, can guarantee that joint 1 can be realized fast and accurately docking of head and the tail in two, guaranteed that a plurality of middle joints 1 have enough intensity behind independent assortment, can prevent again middle joint 1 modification simultaneously.The utility model can make and save in a plurality of axial-flow fans when independent assortment, can simply, quick locate, and enhances productivity.
