A wedge structure according to a preferred embodiment of the present invention will be described in detail below with reference to fig. 1 to 4 of the specification, wherein the wedge structure has a directional moving portion 10, and a wedge groove 11 is formed at a bottom of the directional moving portion 10. The wedge-shaped groove 11 comprises a fast moving area 111 and a self-locking area 112 which are communicated, wherein the fast moving area 111 is close to the bottom surface of the directional moving part 10, namely the fast moving area 111 is used as an opening of the wedge-shaped groove 11 and forms a passage which can be communicated to the self-locking area 112. Obviously, the specific structure of the fast moving region 111 and whether the wedge-shaped groove 11 includes other passages than the fast moving region 111 and the self-locking region 112 are not specifically limited, and the specific structure of the fast moving region 111 will be defined in the following preferred embodiment. The self-locking region 112 is close to the bottom of the wedge-shaped groove 11, and the extending direction of the groove wall of the self-locking region 112 and the moving direction a of the directional moving part 10 keep a predetermined self-locking angle, the driving part 20 for driving the directional moving part 10 to move directionally includes various components or structures, can form self-locking relative to the directional moving part 10 when moving to the self-locking area 112, i.e., there is no relative displacement between the driving part 20 and the directional moving part 10, thereby ensuring that the driving part 20 does not move reversely along the wedge groove 11, i.e., the directional moving part 10 does not move reversely, thereby enabling the driving part 20 to provide a stable driving force output to the directional moving part 10 through the latching region 112, and accordingly, the directional moving part 10 can also provide a stable power output.
Considering that most of the components or structures for driving are implemented as shaft parts, in order to form a good matching relationship between the driving portion 20 and the wedge-shaped groove 11 and ensure the stability of self-locking, as a preferred embodiment of the present invention, the bottom of the wedge-shaped groove 11 is provided with a curved arc structure 113, and the curved arc structure 113 is matched with the self-locking region 112 to form a self-locking groove 1123 suitable for accommodating the driving portion 20, thereby further improving the stability of self-locking of the driving portion 20 relative to the directional moving portion 10. In addition, the arc curved surface structure 113 can provide an avoiding effect for the self-locking area 112, and the self-locking stability of the driving part 20 in the self-locking area 112 is ensured.
Preferably, the self-locking angle β is set to 64 ° to 80 ° according to a transmission characteristic of a mechanical force to ensure stability of self-locking of the driving part 20.
Further preferably, the self-locking angle β is implemented as 67 °, 74 ° or 76 °.
In addition, before the driving part 20 and the directional moving part 10 form a self-locking relationship, the driving part 20 functions to drive the directional moving part 10 to move directionally. Therefore, in order to increase the moving speed of the directional moving part 10 to improve the working efficiency, as a preferred embodiment of the present invention, the extending direction of the groove wall of the fast moving region 111 and the moving direction α of the directional moving part 10 keep a predetermined fast moving angle γ, wherein the fast moving angle γ is set to 30 ° to 64 °, wherein the smaller the fast moving angle, the faster the moving speed of the directional moving part 10 will be during the up and down movement of the driving part 20.
Preferably, the fast-moving angle γ is implemented as 35 °, 40 °, 55 ° or 60 °.
Secondly, the present invention also provides an orientation driving structure, wherein the orientation driving structure 30 comprises a driving portion 20 and the aforementioned orientation moving portion 10, wherein the driving portion 20 is disposed in the wedge-shaped slot 11 in an orientation movable manner along a moving direction α perpendicular to the orientation moving portion 10.
According to the structural characteristics of the wedge-shaped groove 11, for example, for the fast moving region 111 in the wedge-shaped groove 11, when the driving part 20 moves in the fast moving region 111, according to an included angle formed by the fast moving region 111 relative to the moving direction α of the directional moving part 10, the directional moving part 10 can generate a corresponding moving speed, so as to meet the actual requirement and improve the corresponding working efficiency; for example, when the driving portion 20 moves to the self-locking region 112 in the wedge-shaped groove 11, the self-locking with respect to the directional moving portion 10 can be formed, so as to provide a stable driving force output to the directional moving portion 10, and provide a stable power output to the outside from the directional moving portion 10, thereby ensuring the machining precision or improving the machining quality.
As a preferred embodiment of the present invention, the driving portion 20 is implemented as a driving shaft, and the driving portion 20 is engaged with the wedge-shaped groove 11, so as to ensure that the driving portion 20 can move along the inner side surface of the wedge-shaped groove 11, and ensure the self-locking stability between the driving portion 20 and the directional moving portion 10.
In one possible embodiment, the directional movement part 10 is embodied as a latch.
In addition, the present invention further provides a fixing structure 40 for clamping and fixing a positioning element 50, such as a positioning pin or a blind rivet, wherein the fixing structure 40 includes at least two directional driving structures 30, wherein at least two directional moving portions 10 are symmetrically distributed in a line around the positioning element 50 with the positioning element 50 as a center, so as to be able to directionally drive the corresponding directional moving portion 10 to approach and clamp and fix the positioning element 50 when the driving portion 20 moves to the self-locking area 112.
In combination with the foregoing, for the same reason, in the process that the driving portion 20 drives the directional moving portion 10 to clamp the positioning member 50, according to the characteristics of the wedge-shaped groove 11, the fast moving region 111 can improve the clamping speed of the directional moving portion 10, and the self-locking region 112 can improve the clamping stability of the directional moving portion 10 on the positioning member 50, so that the positioning member 50 can still meet the working requirement even if external forces in various directions affect the positioning member 50 during the use of the positioning member 50.
Further preferably, an inclined structure 12 is disposed at an end of the directional moving part 10 close to the positioning member 50, wherein the inclined structure 12 has a lower end 121 and an upper end 122 opposite to each other, and the upper end 122 is close to the positioning member 50. The inclined structure 12 and the moving direction of the directional moving part 10 keep a predetermined pressing angle Δ, and the pressing angle Δ is smaller than the complementary angle of the self-locking angle β. For example, if the self-locking angle β is implemented as 74 °, the complementary angle of the self-locking angle β is 16 °, and the pressing angle Δ is smaller than 16 °, for example, the pressing angle may be implemented as 15 °, 13 °, or 10 °.
Therefore, the downward pulling force of the inclined structure 12 on the positioning element 50 can be effectively amplified through the matching of the pressing angle Δ and the self-locking angle β, so that the positioning element 50 can be effectively stabilized through the matching of the plurality of directional driving structures 30.
