Optionally, as analyzed in conjunction with fig. 5, 6 and 7, fig. 5 is a schematic structural view of a first blade root holder in the propeller of the embodiment of fig. 1; FIG. 6 is a schematic structural view of a second blade root gripping member of the propeller of the embodiment of FIG. 1; FIG. 7 is a schematic view of the assembly of a first root clamp and a second root clamp in the propeller of the embodiment of FIG. 1; the fixing mechanism 110 includes a first blade root clamping piece 111 and a second blade root clamping piece 112 stacked with the first blade root clamping piece 111, wherein a first mounting groove 1111 is formed at one end of the first blade root clamping piece 111 facing the second blade root clamping piece 112, and a second mounting groove 1121 is formed at one end of the second blade root clamping piece 112 facing the first blade root clamping piece 111; the first mounting groove 1111 is spliced with the second mounting groove 1121 to form the mounting hole 190.
Optionally, the propeller 100 includes a fixing member 170, and the first blade root clamping member 111 and the second blade root clamping member 112 are connected and fixed by the fixing member 170.
As will be appreciated with reference to fig. 5 and 6, the securing mechanism 110 specifically includes a first root clamp 111 and a second root clamp 112. The number of the blades 120 on the axial side wall of the first blade root clamping piece 111 perpendicular to the axial direction is equal to that of the blades, and a plurality of first mounting grooves 1111 are uniformly arranged along the radial direction of the second blade root clamping piece 112 (the first mounting grooves 1111 are arranged in a corresponding number according to the number of the blades 120).

Here, an end surface (an end surface perpendicular to the axial direction of the first blade root clamping piece 111) of the first blade root clamping piece 111 provided with the first mounting groove 1111 is connected with an end surface (an end surface perpendicular to the axial direction of the second blade root clamping piece 112) of the second blade root clamping piece 112 provided with the second mounting groove 1121 to assemble the fixing mechanism 110. It is noted that when the first and second blade root clamps 111, 112 are connected, the first mounting slot 1111 of the first and second blade root clamps 111, 112 is correspondingly spliced with the second mounting slot 1121 to form the mounting hole 190 for mounting the blade 120.
As shown in fig. 6, on the end surface of the second blade root holding member 112 away from the end surface thereof where the second mounting grooves 1121 are provided, adjusting grooves 1123 are provided corresponding to the positions and the number of the second mounting grooves 1121. When the blade 120 is mounted on the mounting hole 190 of the fixing mechanism 110, a portion of the adjusting rod 130 (i.e., the second end 131 of the adjusting rod 130) is disposed in the mounting hole 190 along with the blade root 122, and the rest of the adjusting rod 130 passes through the adjusting slot 1123, so that the second end 131 of the adjusting rod 130 is located outside the second blade root holder 112, and thus the second end 131 of the adjusting rod 130 is pulled to adjust the pitch of the propeller 100 without being interfered by the second blade root holder 112. Meanwhile, the slotting direction of the adjusting slot 1123 is consistent with the rotation direction of the blades 120, so that the adjusting rod 130 can rotate in the adjusting slot 1123 by a certain angle around the axial direction of the blade root 122, thereby realizing the adjustable pitch of the propeller 100.
Wherein the first and second blade root clamps 111, 112 connected in the above manner are fixed by at least three fixtures 170. At least three fixing members 170 are symmetrically disposed around the axial direction of the fixing mechanism 110, respectively, so as to fixedly connect the first blade root clamping member 111 and the second blade root clamping member 112. Specifically, the fixing member 170 may be a standard member such as a long screw.
Optionally, as shown in fig. 5, 6 and 7, an annular sliding groove 191 is formed in an inner wall of the mounting hole 190, an annular sliding rail 1221 is formed in a side wall of one end of the blade root 122 close to the blade 121, the annular sliding rail 1221 is located in the annular sliding groove 191, and the annular sliding groove 191 rotates relative to the annular sliding rail 1221 in a rotation plane of the blade 120, so that the blade 120 rotates in the rotation plane.
Specifically, as shown in fig. 5 and 6, a first sliding groove 1112 and a second sliding groove 1122 are respectively disposed on the inner walls of the first mounting groove 1111 and the second mounting groove 1121, wherein after the first blade root clamping piece 111 and the second blade root clamping piece 112 are connected in the above manner, the first sliding groove 1112 and the second sliding groove 1122 are butted to form an annular sliding groove 191 on the inner wall of the mounting hole 190. As shown in fig. 3, an annular sliding track 1221 surrounding the axial direction of the blade root is disposed on the side wall of the blade root 122, wherein when the blade root 122 is disposed in the mounting hole 190, the annular sliding track 1221 is slidably engaged with the annular sliding slot 191, so that when the second end 131 of the adjusting rod 130 is pulled, the blade 120 can rotate around the axial direction of the annular sliding slot 191, thereby adjusting the pitch of the propeller 100. Meanwhile, the sliding fit of the annular slide rail 1221 and the annular slide groove 191 can limit the degree of freedom of the blade 120 in moving along the axial direction thereof, so as to connect and fix the blade 120 and the fixing mechanism 110.
Optionally, as shown in fig. 1, 2 and 8, fig. 8 is a schematic structural diagram of an adjusting mechanism in the propeller of the embodiment of fig. 1; the propeller 100 further includes: the adjusting mechanism 140, the adjusting mechanism 140 is rotatably connected to the fixing mechanism 110 and coaxially disposed with the fixing mechanism 110, the adjusting mechanism 140 has an adjusting portion 144, the adjusting portion 144 is connected to the second end 131 of the adjusting rod 130, and the adjusting portion 144 can drive the second end 131 of the adjusting rod 130 to rotate in the rotation plane of the blade 120, so that the first end 132 of the adjusting rod 130 drives the blade 120 to rotate.
Optionally, the adjusting portion 144 is provided with a limiting hole 141, and the second end 131 of the adjusting rod 130 is embedded in the limiting hole 141; the adjusting portion 144 drives the second end 131 of the adjusting rod 130 disposed in the limiting hole 141 to rotate in the rotation plane of the blade 120.
Optionally, as shown in fig. 1 and 2, the propeller 100 further includes a locking member 150, and the adjusting mechanism 140 is locked with the fixing mechanism 110 by the locking member 150 after the adjusting lever 130 is adjusted.
Specifically, the adjusting mechanism 140 is a disk-shaped structure, one end of the adjusting mechanism 140 is connected to an end surface of the second blade root clamping element 112, which is away from the end provided with the second mounting groove 1121, and the adjusting mechanism 140 is coaxial with the fixing mechanism 110 in the axial direction. A plurality of limiting holes 141 are uniformly arranged on the adjusting mechanism 140 along the axial direction thereof, and the number of the limiting holes 141 corresponds to the number of the paddles 120 (i.e., several paddles correspond to several limiting holes 141). The limiting hole 141 is a concrete structure embodiment of the adjusting portion 144 on the adjusting mechanism 140. As described above, the second end 131 of the adjustment rod 130 is embedded in the limiting hole 141, and the adjustment mechanism 140 is rotated around the axial direction of the fixing mechanism 110, so that the inner wall 143 of the limiting hole 141 pushes the second end of the adjustment rod 130 while the limiting hole 141 rotates along with the adjustment mechanism 140, so that the adjustment rod 130 rotates around the axial direction of the blade 120 as a rotation axis. The adjusting mechanism 140 is rotated in the above manner, so that the adjusting rods 130 can be simultaneously driven to rotate around the axial direction of the blades 120 as a rotating axis at one time, and the blades 120 are driven to rotate around the axial direction, so as to adjust the pitch of the propeller 100. The adjusting mechanism 140 is rotatable about its axial direction relative to the fixing mechanism 110 during pitch adjustment of the propeller 100, so that the pitch of the propeller 100 can be adjusted by rotating the adjusting mechanism 140 during pitch adjustment of the propeller 100.
The adjusting mechanism 140 is further provided with a plurality of (at least three) third sliding grooves 142 uniformly arranged around the axial direction thereof, wherein a plurality of locking members 150 corresponding to the number of the third sliding grooves 142 respectively pass through the third sliding grooves 142, and press-lock the adjusting mechanism 140 on the fixing mechanism 110 along the fixing mechanism 110. Specifically, for example, as shown in fig. 1, 2, 5 and 6, the locking member 150 has a locking cap 151 and a threaded connection column 152, the first blade root clamping member 111 and the second blade root clamping member 112 are respectively provided with a threaded hole 1113 and a positioning through hole 1124 which are matched with the locking member, wherein the connection columns 152 of the three locking members 150 pass through the third sliding groove 142 and the positioning through hole 1124 and are in threaded fit with the threaded hole 1113 to coaxially and radially fix the adjusting mechanism 140, the first blade root clamping member 111 and the second blade root clamping member 112 so as to prevent the two from moving relative to each other along the radial direction thereof, and meanwhile, the brim of the locking cap 151 of the locking member 150 abuts against the end surface of the adjusting mechanism 140 which is away from the end connected with the second blade root clamping member 112 to provide an abutting force for the adjusting mechanism 140, so as to lock the adjusting mechanism 140 on the fixing mechanism 110, at this time, the adjusting mechanism 140 is acted by the abutting force, such that adjustment mechanism 140 is neither axially movable along the fixation mechanism relative to fixation mechanism 110 nor axially rotatable about fixation mechanism 110. The abutting force applied by the locking cap 151 to the adjusting mechanism 140 can be adjusted by adjusting the degree of the threaded fit between the connecting column 152 and the threaded hole 1113.
It should be noted that the third sliding slot 142 allows the adjusting mechanism 140 to rotate relatively to the locking member 150 in the axial direction around the fixing mechanism 110 (i.e. the adjusting mechanism 140 can rotate around its own axis), in other words, the locking member 150 serves to connect the fixing adjusting mechanism 140 and the fixing mechanism 110 (i.e. the above description), on the one hand, and on the other hand, the locking member 150 provides a guiding function for the adjusting mechanism 140 to rotate around its own axis. Specifically, for example, when the propeller 100 needs to adjust the pitch, the abutting force can be reduced or eliminated by adjusting the degree of matching between the locking member 150 and the threaded hole 1113 (at this time, the locking member 150 still coaxially and radially fixes the adjusting mechanism 140, the first blade root clamping member 111 and the second blade root clamping member 112), so that the adjusting mechanism 140 can rotate around its own axial direction relative to the fixing mechanism 110, wherein the third sliding slot 142 corresponds to the guiding slot, and the locking member 150 corresponds to the guiding rail, and when the adjusting mechanism 140 rotates, while the third sliding slot 142 rotates along with the adjusting mechanism 140, since the plurality of locking members 150 radially pass through the corresponding third sliding slots 142, the inner wall of the third sliding slot 142 is always subjected to the guiding force provided by the locking member 150, which is radially perpendicular to the adjusting mechanism 140, and acts on the axial center of the adjusting mechanism 140, so that the adjusting mechanism 140 can relatively rotate around the axial direction of the fixing mechanism 110 relative to the locking member 150 and the fixing mechanism 110 .
In other words, the plurality of locking members 150 are respectively engaged with the plurality of third sliding grooves 142, and as the adjusting mechanism 140 rotates relative to the fixing mechanism 110, the end of the locking member 150 slides in the third sliding groove 142, so that the relative rotation between the adjusting mechanism 140 and the locking member 150 always rotates around the central axis of the plurality of third sliding grooves 142, that is, when the adjusting mechanism 140 is adjusted, the adjusting mechanism 140 always rotates around the axial direction thereof, thereby driving the plurality of adjusting rods 130 to rotate (for example, the three adjusting rods 130 shown in fig. 1), and further adjusting the pitch of the propeller 100. After the pitch of the propeller 100 is adjusted, the adjusting mechanism 140 and the fixing mechanism 110 can be fixed only by adjusting the degree of the thread fit between the connecting column 152 of the locking member 150 and the threaded hole 1113 to increase the abutting force, so as to restrict the rotation of the adjusting rod 130, and further fix the blades 120, so that the included angle of the blade surface of the blade 121 with respect to the axial vertical end surface of the fixing mechanism 110 is unchanged, and the pitch of the propeller 100 is kept unchanged.
Optionally, as analyzed with reference to fig. 1, fig. 6, and fig. 8, a first scale mark 162 is disposed on the adjusting mechanism 140, a second scale mark 161 corresponding to the first scale mark 162 is disposed on the fixing mechanism 110, and a difference between the first scale mark 162 and the second scale mark 161 is used to mark a rotation angle of the adjusting mechanism 140 relative to the fixing mechanism, so as to mark a rotation angle of the blade 120.
Specifically, the second scale mark 161 and the first scale mark 162 are respectively arranged on the side wall of the connection end of the adjusting mechanism 140 and the second blade root clamping member 112, for example, the second scale mark 161 is used as a scale pointer, the first scale mark 162 is a scale value, when the adjusting mechanism 140 rotates relative to the fixing mechanism 110, the second scale mark 161 points to the scale value corresponding to the first scale mark 162 on the fixing mechanism 110, so as to obtain the specific rotation angle of the adjusting mechanism 140 relative to the fixing mechanism 110, so as to determine the pitch adjustment value of the propeller 100, and further greatly improve the pitch adjustment accuracy of the propeller 100.
In summary, unlike the prior art, the propeller 100 of the present application includes a fixing mechanism 110, a blade 120, and an adjusting rod 130. The propeller 100 adopting the technical means can drive the blades to rotate around the axial direction of the blades by adjusting the second ends 131 of the adjusting rods 130 so as to adjust an included angle between the blade surfaces of the blades 120 and a plane perpendicular to the axial direction of the fixing mechanism 110, namely, adjust an included angle between the blade surfaces of the blades 120 and a rotating plane of the propeller 100, thereby realizing the adjustment of the pitch of the propeller 100, further meeting the use requirements of users under different pitch working conditions and greatly reducing the production cost of the propeller 100. Meanwhile, the fixing mechanism 110 is rotatably connected with the blade 120, so that when the pitch of the propeller is adjusted, the blade 120 and the fixing mechanism 110 do not need to be disassembled, and the pitch of the propeller 100 can be adjusted by stirring the second end 131 of the adjusting rod 130, thereby greatly improving the working efficiency. Wherein, propeller 100 still includes adjustment mechanism 140 and locking piece 150, through the adjustment mechanism 140 and the locking piece 150 of above-mentioned relation of connection, propeller 100 can be through adjusting adjustment mechanism 140 and then the quick pitch of adjusting propeller 100 to lock through locking piece 150, thereby make propeller 100's pitch regulation more high-efficient, and then promoted user's work efficiency greatly. In addition, the propeller 100 is further provided with a first scale mark 162 and a second scale mark 161, so that a user can more accurately adjust the pitch of the propeller 100 required by the user, and the pitch adjustment precision of the propeller 100 is greatly improved.
