Detailed Description
The claimed technical solution of the present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 5, a hidden hinge in this embodiment includes a frame connecting seat 1 connected to a frame, a fan connecting seat 2 connected to a fan, a first connecting rod 3, a second connecting rod 4, a third connecting rod 5, and a swinging member 6.
In this embodiment, the frame connecting seat 1 is an L-shaped structure, and the frame connecting seat 1 is provided with a quincunx hole connected with a frame screw. The frame body connecting seat 1 with the L-shaped structure can be connected with the side edge and the bottom edge of the frame body at the same time, and the screw loosening can be avoided by adopting the quincuncial holes for screw connection, so that the connection stability is improved. Similarly, the fan connecting seat 2 is in an L-shaped structure, and the fan connecting seat 2 is provided with a quincunx hole connected with a frame body screw. The fan body connecting seat 2 with the L-shaped structure can be connected with the side edge and the bottom edge of the fan body at the same time, and the screw connection is carried out by adopting the quincuncial holes, so that the loosening of the screws can be avoided, and the connection stability is improved.
The frame connecting seat 1 is pivoted with the first connecting rod 3 and the swinging piece 6 at the same time, the second connecting rod 4 is provided with three pivoting points and is pivoted with the fan connecting seat 2, the first connecting rod 3 and the swinging piece 6 in sequence, and two ends of the third connecting rod 5 are respectively pivoted with the first connecting rod 3 and the fan connecting seat 2.
In this embodiment, an arc-shaped guide groove 11 is left on the frame body connecting seat 1, the swinging member 6 is in sliding fit with the guide groove 11, and a gasket 7 with the arc-shaped guide groove 11 is arranged between the frame body connecting seat 1 and the swinging member 6. The gasket 7 can reduce the friction between the frame body connecting seat 1 and the swinging piece 6, avoid abrasion between the frame body connecting seat and the swinging piece, and simultaneously facilitate noise reduction and resistance reduction. The guide groove 11 can guide the swinging piece 6 to swing along an arc line, and can offset the centrifugal action generated when the swinging piece 6 rotates to a certain extent, so as to keep the pivot between the swinging piece 6 and the frame body connecting seat 1 stable and prevent the deviation.
In addition, in this embodiment, washers 8 are disposed on the pivot points between the frame connecting seat 1 and the first connecting rod 3, between the second connecting rod 4 and the fan connecting seat 2, between the first connecting rod 3 and the swinging member 6, and between the third connecting rod 5 and the first connecting rod 3 and the fan connecting seat 2. The friction between the parts can be reduced by the washers 8, avoiding wear between the parts while facilitating noise reduction and reducing drag.
