Embodiment:
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1 to shown in Figure 8, fan blade of the present invention, it comprises the fan blade seat 1 that is in the central position, be arranged on fan blade seat 1 edge and the blade 2 that is connected as a single entity with fan blade seat 1 and be installed in fan blade seat end cap 3 on the fan blade seat 1.Be provided with a core 1.1 in the described fan blade seat 1, the axial hole 1.11 that the output shaft that described seat core 1.1 is provided with the power supply motivation inserts.Described fan blade also comprises the fixing device on the output shaft that fan blade can be fixed on motor, and described fixing device is arranged on the fan blade seat 1.
Described fixing device comprises pushing block 4, limited post 5 and is connected fastener 6.For realizing that described pushing block 4 is movably arranged on the fan blade seat 1, the edge of described fan blade seat 1 is provided with the limited step 1.2 that the aft bulkhead 4.1 with pushing block 4 matches, and the madial wall of described fan blade seat end cap 3 is provided with the spacing block set 3.1 that the side projection 4.2 with pushing block 4 matches.Described limited post 5 is fixedly installed on the fan blade seat 1, and for ease of machine shaping, described limited post 5 is connected as a single entity with fan blade seat 1.Described connection fastener 6 comprises inserted part and the spacing pressure-bearing portion on limited post 5 on the output shaft that can be connected to motor.The front end of the top of described inserted part and pushing block 4 matches, and described pressure-bearing portion is connected the end of inserted part.
Described inserted part is made of top bending section 7 and the two top straightways 8 that are connected top bending section 7 two ends, and described two top straightways 8 distance each other from top to bottom reduces gradually.
For ease of bending and molding, described top bending section 7 is formed by the fillet bending.The front end of the top of described inserted part and pushing block 4 matches, be that the male part of described top bending section 7 and the front end of pushing block 4 match, in fact the front end that refers to described pushing block 4 is provided with the square hole 4.3 that can stretch into for top bending section 7, and the middle part of described top bending section 7 is provided with and is convenient to and the contacted straightway 7.1 of the inwall of square hole 4.3.Described square hole 4.3 is convenient to pushing block 4 with the setting of straightway 7.1 and is promoted to be connected fastener 6.
Described two top straightways 8 are positioned at the top of the axial hole 1.11 of described seat core 1.1.Be connected on the output shaft of motor for ease of two top straightways 8, the output the tip of the axis of described motor is provided with the limited impression 13 that matches with two top straightways 8, and this limited impression 13 is actually an annular groove.
Described pressure-bearing portion is made up of the both sides bending section 9 consistent with top bending section 7 opening directions.Described both sides bending section 9 all forms through the fillet bending.In fact the end that described pressure-bearing portion is connected the inserted part refers to that described both sides bending section 9 is connected to the end of two top straightways 8.The inner fovea part of described both sides bending section 9 matches with corresponding limited post 5 respectively, thereby makes both sides bending section 9 spacing on corresponding limited post 5, even pressure-bearing portion is spacing on limited post 5.
Also be arranged with guide holder 12 on the described inserted part, described guide holder 12 is fixedly installed on the fan blade seat 1.Described guide holder 12 is the bar blocks of two band endoporus, is set in the upper and lower of described two top straightways 8 respectively.Arranging of described guide holder 12 can be played leading role to connecting the moving direction of fastener 6 under the promotion of pushing block 4.
For ease of being connected of inserted part and pressure-bearing portion, also be provided with joint between continuous top straightway 8 and the Edge Bend section 9.Described joint is made of end straightway 11 and the end bending section 10 opposite with top bending section 7 opening directions.Bending section of the described end 10 forms through the fillet bending.Straightway of the described end 11 is connected with Edge Bend section 9, and bending section of the described end 10 is connected with top straightway 8.The setting of this joint also helps the pressure-bearing of pressure-bearing portion, makes pressure-bearing portion gather more spring-back force in the process of pushing block 4 promotion connection fasteners 6.
Described inserted part, pressure-bearing portion and to connect the joint of inserted part and pressure-bearing portion all one-body molded namely form through fillet bending repeatedly by connecting fastener 6.
In the time of fan blade need being fixed on the output shaft of motor, as shown in Figure 1, installing at fan blade seat 1 and to connect fastener 6 and fan blade seat end cap 3, the output shaft of motor is inserted in the axial hole 1.11 of seat core 1.1 of fan blade seat 1.Promote pushing block 4 this moment, makes pushing block 4 promote to connect fastener 6 and move forward, and along with the movement that connects fastener 6, the distance between the two top straightways 8 of inserted part increases gradually, and the both sides bending section 9 of pressure-bearing portion then pushes limited post 5, and spacing on limited post 5.Press fan blade seat 1 this moment, and the output shaft of the motor in the axial hole 1.11 that is inserted into a core 1.1 is extend between the two top straightways 8.Unclamp pushing block 4 this moment, connects fastener 6 resiliences, the distance between the two top straightways 8 of inserted part reduce gradually and the limited impression 13 on spacing output shaft top at motor on, final fan blade is completely fixed on the output shaft of motor through fixing device.
As needs fan blade is disassembled from motor output shaft, promote pushing block 4 earlier, making distance between the two top straightways 8 of inserted part increase to the output shaft that can make motor spins off between two top straightways 8, just can take off the output shaft of fan blade from motor this moment, very simple, convenient.
On the output shaft that is fixed on motor that fan blade of the present invention can be very firm, can not fall down, as safe as a house, and when dismounting is also very simple, convenient.
