Detailed Description
To further understand the contents, features and functions of the present invention, the following embodiments are described.
As shown in fig. 1-2, an embodiment of the present invention provides a self-locking positioning hinge, which includes a first fixing plate 1 and a second fixing plate 2, the first fixing plate 1 is fixedly connected with a pair of first bushings 3, the second fixing plate 2 is fixedly connected with a pair of second bushings 4, pin shafts 5 are inserted into the first bushings 3 and the second bushings 4, the pair of first bushings 3 are disposed outside the pair of second bushings 4, a pair of retaining bushings 6 is disposed between the pair of second bushings 4, the retaining bushings 6 are concentrically disposed with the second bushings 4, the end surface of the second bushings 4 is provided with trapezoidal protrusions 41, the end surface of the retaining bushings 6 is provided with trapezoidal grooves 61, the trapezoidal grooves 61 are matched with the trapezoidal protrusions 41, a compression spring 7 is abutted between the pair of retaining bushings 6, the compression spring 7 is always kept in a compressed state, and a slider is fixedly connected to the inner sides of the retaining bushings 6, the pin shaft 5 is provided with a sliding groove 51, the direction of the sliding groove 51 is parallel to the axial direction of the pin shaft 5, and the sliding block is connected with the sliding groove 51 in a sliding manner.
The trapezoidal grooves 61 are equally spaced.
The first shaft sleeve 3 is abutted with a plastic rubber ring 8, the plastic rubber ring 8 and the first shaft sleeve 3 are arranged concentrically, and the other side face of the plastic rubber ring 8 is abutted with the second shaft sleeve 4.
The outer surfaces of the first shaft sleeve 3, the second shaft sleeve 4 and the clamping shaft sleeve 6 are parallel and level with each other.
The corners of the first fixing plate 1 and the second fixing plate 2 are provided with rounded transitions.
The first fixing plate 1 and the second fixing plate 2 are provided with stepped through holes 11.
Specifically, referring to fig. 1-2, the first fixing plate 1 and the first fixing plate 1 are used for connecting with an external mechanism, the first fixing plate 1 or the second fixing plate 2 is rotated, the second shaft sleeve 4 and the clamping shaft sleeve 6 are rotated in opposite directions, the trapezoidal protrusion 41 of the second shaft sleeve 4 and the trapezoidal groove 61 of the clamping shaft sleeve 6 are rotated to opposite positions, and the clamping shaft sleeve 6 engages the trapezoidal groove 61 with the trapezoidal protrusion 41 under the elastic force of the compression spring 7, so as to form self-locking. Under the self-locking state, the fixed plate is rotated by continuously applying the thrust, and the trapezoidal groove 61 and the trapezoidal convex block 41 have inclined edges, so that the hinge is in a contact self-locking state when the trapezoidal convex block 41 slides out of the trapezoidal groove 61 when certain force is reached. The blocking shaft sleeve 6 is connected with the sliding groove 51 on the pin shaft 5 in a sliding mode through the sliding block, and the direction of the sliding groove 51 is parallel to the axial direction of the pin shaft 5, so that the blocking shaft sleeve 6 can only slide along the axial direction of the pin shaft 5, and cannot rotate due to friction force applied by the trapezoid concave blocks.
The trapezoidal grooves 61 are arranged at equal intervals and angles, and are generally self-locked once every 180 degrees or once every 90 degrees. The butt of first axle sleeve 3 has plastics rubber ring 8, and plastics rubber ring 8 sets up with first axle sleeve 3 is concentric, and the another side of plastics rubber ring 8 offsets with second axle sleeve 4, and plastics rubber ring 8 can avoid the direct rigid friction of two axle sleeves when using, effectively reduces the wearing and tearing of axle sleeve, protection hinge outward appearance. The outer surfaces of the first shaft sleeve 3, the second shaft sleeve 4 and the clamping shaft sleeve 6 are parallel and level with each other, and the appearance integrity is better. The edge of the first fixing plate 1 and the second fixing plate 2 is provided with a fillet transition, so that the scratch to a human body caused by the edge is prevented when the human body is installed. The first fixing plate 1 and the second fixing plate 2 are provided with stepped through holes 11, when the screws are used for connection, the head of each screw does not protrude out of the fixing plates, and the screw heads can be embedded into the through hole covers to hide the screw heads, so that the appearance effect of the hinge is improved.
