Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than those herein described, and those skilled in the art may readily devise numerous other arrangements that do not depart from the spirit of the invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
The invention discloses a rotor fastener, the cross section of which comprises at least three base points and side edges connecting two adjacent base points, the cross section is extended along the vertical direction to obtain a columnar rotor fastener, the middle part of the rotor fastener is provided with a tightening piece, and the rotor fastener is driven to rotate by the tightening piece.
The linear distance between each base point on the rotor fastener and the base point at the opposite end of the side from the base point is different. The rotor fastener is used between two outer side walls, one base point is close to the first outer side wall, the side edge opposite to the base point is close to the second outer side wall, the base point is contacted with the first outer side wall, the side edge opposite to the base point is contacted with the second outer side wall during the rotating fastening process of the rotor fastener, and the straight line distance between the base point and the point or line segment on the side edge contacted with the second outer side wall is increased, so that the outward tensioning force is generated on the two outer side walls.
Example 1
As shown in fig. 2, the cross-sectional shape of the rotor fastener of this embodiment is shown in fig. 3, the cross-section includes three base points and sides connecting two adjacent base points, and the cross-section shown in fig. 2 extends in the vertical direction, so that a columnar rotor fastener can be obtained.
The three base points of the cross section are respectively A point, B point and C point, and the straight line distances among the three base points are different, namely the lengths of the line segment AB, the line segment BC and the line segment CA are different. The difference in length includes that the straight line distances between the three base points are all different, and also includes that two straight line distances among the three straight line distances are the same but different from another straight line distance.
The center of the rotor fastener is provided with a tightening piece 4, and the tightening piece 4 can be a tightening hole or a tightening bulge. When the tightening piece is a tightening hole, the tightening hole can be a through hole or a blind hole. The tightening holes can be inner hexagonal holes and quincuncial holes, and can also be holes with other shapes. Likewise, when the tightening member is an upturned projection, the cross-section of the upturned projection may be hexagonal, quadrilateral, cross-shaped, or any other shape. By means of the tightening piece 4, a rotation of the rotor fastener around its centre is achieved.
In the cross section, the side connecting the point A and the point C is a side I1, the side connecting the point A and the point B is a side II 2, and the side connecting the point B and the point C is a side III 3. Fig. 3 shows an initial state of the rotor fastener just placed between two outer side walls to be tightened, wherein the side where the base point a is located is close to one of the outer side walls, and the side where the side BC is located is close to the other outer side wall. Through the tightening piece 4 in the center of the rotor fastener, the rotor fastener rotates clockwise, in the rotating process, the base point A contacts with the first outer side wall, the side III 3 opposite to the base point A contacts with the second outer side wall, the linear distance between the contact surface or the contact line section time of the point A and the side III 3 and the second outer side wall is gradually increased, the size of the rotor fastener between the two outer side walls is gradually increased, and accordingly tension is generated on the outer side walls of the two sides, the side where the base point A is located generates outward tension on the outer side wall adjacent to the side where the base point A is located, and the side where the side BC is located generates outward tension on the outer side wall adjacent to the side where the base point A is located. When the rotor fastener is rotated to the position shown in fig. 4, the rotor fastener cannot continue to rotate, at which point the tensioning force exerted by the rotor fastener against the outer side walls of the two sides reaches a maximum. In this embodiment, the linear distance between the point a and the point C is greater than the linear distance between the point a and the point B and less than the linear distance between the point B and the point C.
In the invention, the side edge is an arc line which can be continuous, and the corresponding side surface is an arc surface; the three side surfaces can also be edges formed by connecting a plurality of line segments, a plurality of arc lines or a plurality of tooth-shaped edges end to end. The distance between each point on the side involved in the actual fastening process and its corresponding base point must be varied, e.g. gradually increased, so that the side involved in the actual fastening process cannot be a continuous straight line. The side edges not involved in the actual fastening process may be continuous straight lines, continuous arcs, or the side edge forms described above.
When the straight line distance between two base points of one side edge and a third base point opposite to the side edge is different, the connecting line distance between each point on the side edge and the third base point gradually increases along the direction from small to large; or the linear distance between the base points is gradually reduced along the direction from large to small. As shown in fig. 3, two base points of the side ii 2, namely, a point a and a point B, have different linear distances from a point C opposite to the side ii 2, and the linear distance between the point B and the point C is greater than the linear distance between the point a and the point C, and the distance between each point on the side ii 2 and the point C increases in sequence from the point a to the point B; or the direction from the point B to the point A is sequentially reduced. The two base points of the side III 3, namely a point B and a point C, the straight line distances between the two points and a point A opposite to the side III 3 are different, the straight line distance between the point B and the point A is smaller than the straight line distance between the point C and the point A, and the distances between the points on the side III 3 and the point A are sequentially increased from the point B to the point C; or the direction from the point C to the point B is sequentially reduced.
As shown in fig. 5, the rotor fastener placed in the elongated groove of the profile 6 is in a fastened working state, the side edge where the base point a on the cross section is located is in contact with the side wall i 7, and an outward tension is applied to the side wall i 7; the side of the cross-section where the side BC is located is in contact with the side wall ii 8 and applies an outward tension to the side wall ii 8. The sheet 5 is firmly secured in the elongated slot of the profile 6 by the tension applied by the rotor fasteners.
Fig. 4 is a schematic cross-sectional view of the rotor fastener in a fastened state, where the side at the base point a contacts the first outer sidewall and the side at the side BC contacts the second outer sidewall. As mentioned above, the side wall BC may be a continuous arc line or formed by connecting several line segments end to end, so that when the side face where the side wall BC is located contacts the second outer side wall, it may be a line contact, which is reflected on the cross section as a contact point; or may be in surface contact, in cross-section, i.e. a line of contact. In fig. 4, the side edge at the point E on the side edge BC contacts the second outer sidewall, and the side edge BC and the second outer sidewall are in line contact. The closer the AE line is to perpendicular to the outer sidewall, the more advantageous the locking of the rotor fastener.
Example 2
In this embodiment, the side BC and the side AB are each formed by connecting a plurality of line segments end to end, and specifically, each of the eight line segments is formed by connecting eight line segments.
The distance between points on the side BC and the point a increases in sequence from the point B to the point C, so that the side BC and the base point a opposite to the side BC can participate in the actual fastening process. Similarly, the distance between points on the side AB and points C increases in order from point a to point B, so that the side AB and the base point C opposite to the side AB can participate in the actual fastening process. While the side AC is always unable to participate in the clockwise rotational tightening process of the rotor fastener. In this embodiment, the side AC adopts an arc, which can prevent the base point from being too sharp, and improves the smoothness of the base point.
The number of segments constituting the side BC and the side AB is not limited to eight as described in the present embodiment, and other numbers of segments may be adopted, and the specific number of segments needs to be determined according to the length of the side BC and the actually required machining precision.
Otherwise, the same as in example 1 was conducted.

Unlike example 1, the following is: as shown in fig. 7, in this embodiment, the curvature of the side BC toward one side of the rotation direction of the rotor fastener is the largest, and the curvature of the side BC along the direction opposite to the rotation direction of the rotor fastener sequentially becomes smaller, so that the rotor fastener is quickly fastened through the portion with the large curvature first, and then is firmly locked through the portion with the small curvature in the rotation fastening process, thereby improving the fastening efficiency and the fastening effect of the rotor fastener.
Otherwise, the same as in example 1 was conducted.
Example 4
Unlike example 1, the following is: as shown in fig. 8, in this embodiment, the side AB is located facing the first outer sidewall, and the base point C opposite to the side AB is located facing the second outer sidewall. During clockwise rotational tightening of the rotor fastener, the side AB contacts the first outer sidewall and a point C opposite the side AB contacts the second outer sidewall. The linear distance between the base point C and the point or line segment on the side AB contacting the second outer side wall is gradually increased, and the tensioning force on the two outer side walls is gradually increased in the increasing process, so that the fastening effect is achieved.
According to the present embodiment and embodiment 2, the side AC and the base point B opposite to the side AC in the rotor fastener cannot always participate in the clockwise rotation fastening process of the rotor fastener.
Otherwise, the same as in example 1 was conducted.

Unlike example 1, the following is: as shown in fig. 9, in this embodiment, the side AC that does not participate in the actual fastening process is a straight line, and no arc is used, that is, the side of the rotor fastener where the side AC is located is a square surface.
Otherwise, the same as in example 1 was conducted.

Of course, the number of tooth edges is not limited to the number disclosed in the present embodiment. By arranging the side edges into the tooth shape, the rotor fixing piece can only rotate unidirectionally, and the reverse rotation of the rotor fixing piece is effectively prevented. The side AC which does not participate in the actual fastening process can be an arc line or a straight line, and can also be formed by connecting a plurality of sections of tooth-shaped sides end to end.
Otherwise, the same as in example 1 was conducted.
Example 7
Unlike example 1, the following is: as shown in fig. 11, in this embodiment, the side AB and the side BC that participate in the actual fastening process are connected by a plurality of sections of concave arcs, and in this embodiment, the side AB and the side BC are each connected by eight sections of concave arcs. . The number of concave arcs is not limited to the number disclosed in the present embodiment. The side AC which does not participate in the actual fastening process can be an arc line or a straight line, and can also be formed by connecting a plurality of sections of concave arcs end to end.
Otherwise, the same as in example 1 was conducted.
Example 8
Unlike example 1, the following is: as shown in fig. 12, in this embodiment, the side AB and the side BC that participate in the actual fastening process are formed by connecting a plurality of sections of convex arcs, and in this embodiment, the side AB and the side BC are formed by connecting eight sections of convex arcs. The number of convex arcs is not limited to the number disclosed in this embodiment. The side AC which does not participate in the actual fastening process can be an arc line or a straight line, and can also be formed by connecting a plurality of sections of convex arc lines end to end.
Otherwise, the same as in example 1 was conducted.
Example 9
Unlike example 1, the following is: as shown in fig. 13, in the present embodiment, the linear distance between the point C and the point B is equal to the linear distance between the point a and the point C, and the linear distance between the point a and the point B is smaller than the linear distance between the point C and the point B, that is, bc=ac > AB, when the side BC and the base point a opposite to the side BC participate in the actual fastening process. The side BC which can finally apply the outward tension to the outer side wall can be a continuous arc or formed by connecting a plurality of line segments, a plurality of tooth-shaped edges and a plurality of arcs end to end. The side AB and the side AC may be continuous straight lines, continuous arcs, or may be formed by connecting a plurality of line segments, a plurality of tooth-shaped edges, and a plurality of arcs end to end.
Otherwise, the same as in example 1 was conducted.
Example 10
Unlike example 1, the following is: the cross-sectional shape of the rotor fastener of this embodiment is shown in fig. 14, the cross-section includes four base points and side edges connecting two adjacent base points, and the cross-section shown in fig. 14 is extended in the vertical direction, so that a columnar rotor fastener can be obtained.
The four base points of the cross section are respectively A point, B point, C point and D point, and the sides connecting the four base points are respectively side AB, side BC, side CD and side AD. The straight line distance between any base point and the base points at the two ends of the side opposite to the base point is different, namely the lengths of the line segment AB, the line segment BC, the line segment CA and the line segment BD are different, and BD > BC > CA > AB. By providing four base points, the support size of the rotor fastener can be increased.
As shown in fig. 15 (a) and 15 (b), the base point a is directed toward the second outer side wall, and the side BC opposite to the base point a is directed toward the first outer side wall. The rotor fastener is rotationally tightened in a clockwise direction, at which point a is progressively more distant from the point or line segment on the side BC that contacts the first outer sidewall, thereby creating tension on the outer sidewalls of both sides until the rotor fastener cannot continue to rotate. The base point a and the side BC opposite to the base point a then participate in the actual fastening process of the rotor fastener.
As shown in fig. 16 (a) and 16 (b), the base point C is directed toward the first outer side wall, and the side AB opposite to the base point C is directed toward the second outer side wall. The rotor fastener is rotationally fastened in a clockwise direction, at which point the distance between point C and the point or line segment on the side AB that is in contact with the second outer sidewall gradually increases, thereby generating tension on the outer sidewalls of both sides until the rotor fastener cannot continue to rotate. The base point C and the side AB opposite the base point C then take part in the actual fastening process of the rotor fastening.
As shown in fig. 17 (a) and 17 (B), the base point B is directed toward the second outer side wall, and the side CD opposite to the base point B is directed toward the first outer side wall. The rotor fastener is rotationally tightened in a clockwise direction, at which point the distance between point B and the point or line segment on the side CD that contacts the first outer sidewall gradually increases, thereby creating tension on the outer sidewalls of both sides until the rotor fastener cannot continue to rotate. The base point B and the side CD opposite to the base point B now participate in the actual fastening process of the rotor fastener.
In the actual use process, the side AD is not involved in the clockwise rotation fastening process of the rotor fastener all the time, so the side AD is a straight line, and the side face of the rotor fastener where the side AD is located is a square face.
Otherwise, the same as in example 1 was conducted.
