The sliding rods 3 extend along the front-back direction D1 and are disposed in the disposing groove 11 at intervals, and both ends of each sliding rod 3 are slidably disposed on the secondary rail sections 122 of the two concave rails 12. In this embodiment, the hinge 100 further includes a sliding frame 5 disposed in the setting groove 11, one of the sliding bars 3, which is the farthest away from the sliding member 2, is formed on the sliding frame 5, the sliding frame 5 further has a tail end sliding bar 51 which is farther away from the sliding member 2 than the one sliding bar 3 and extends along the front-back direction D1, and a connecting portion 52 connected between the one sliding bar 3 and the tail end sliding bar 51, two ends of the tail end sliding bar 51 are slidably disposed on the sub-rail sections 122 of the two concave rails 12, but the hinge 100 may not include the sliding frame 5, and the one sliding bar 3 may be an independent element, which is not limited in this embodiment.
The torsion pieces 4 are respectively tightly fitted and relatively rotatably disposed between the adjacent setting rod 22 and the adjacent sliding rod 3 and between the adjacent two sliding rods 3, so as to connect the setting rod 22 of the sliding piece 2 and the sliding rod 3 in series. In the present embodiment, two torsion members 4 spaced apart in the front-back direction D1 are respectively disposed between the adjacent setting rod 22 and the sliding rod 3 and between the adjacent two sliding rods 3, and the four torsion members 4 disposed on the same sliding rod 3 are overlapped with each other along the front-back direction D1, so that the structure formed by the setting rod 22, the sliding rod 3 and the torsion members 4 is more stable, but in other embodiments, the number and arrangement of the torsion members 4 may be adjusted as required, which should not be limited by the present embodiment.
In the embodiment, each torsion member 4 has a plurality of torsion pieces 41 overlapped in the front-back direction D1, the torsion pieces 41 may be metal pieces manufactured by a precision stamping process, but the torsion pieces 41 may also be pieces manufactured by other methods, and further, the torsion member 4 may not be formed by the torsion pieces 41, which is not limited herein.
Each torsion piece 41 has a middle section 411 between the adjacent setting rod 22 and the adjacent slide rod 3 or between two adjacent slide rods 3, and two elastic sections 412 oppositely extending from the middle section 411, the middle section 411 is formed with two convex portions 411a corresponding to the two elastic sections 412, and each elastic section 412 has two elastic arms 412a clamping the corresponding setting rod 22 or the corresponding slide rod 3 with a mutual tight fit with the corresponding convex portions 411 a. The protruding portion 411a of the torsion bar 41 and the elastic arm 412a are used to tightly fit the torsion piece 4 and rotatably set the setting rod 22 and the sliding rod 3.
Referring to fig. 2, 3 and 5 to 7, when the sliding member 2 slides from the extended position to the retracted position, the sliding rod 3 slides along the two concave rails 12 along with the setting rod 22 of the sliding member 2 through the connection of the torsion member 4. In this embodiment, when the slider 2 is located at the extended position, the sliding rods 3 are disposed on the secondary rail sections 122 of the two concave rails 12, and when the slider 2 is located at the retracted position, the sliding rods 3 all slide to the primary rail sections 121 of the two concave rails 12, in a variation, when the slider 2 is located at the retracted position, only at least one of the sliding rods 3 may slide to the primary rail sections 121 of the two concave rails 12, or may not slide to the primary rail sections 121 of both the concave rails 12, which is not limited in this embodiment.
In the present embodiment, the secondary track segments 122 of the two groove tracks 12 extend along an irregular curve, but the extending path of the secondary track segments 122 of the groove tracks 12 can be adjusted according to the requirement. When the sliding rod 3 is to slide along the secondary rail segment 122 or the primary rail segment 121 of the two groove rails 12 along with the setting rod 22 of the sliding member 2 by the connection of the torsion member 4, the torsion member 4 will rotate relative to the setting lever 22 of the slider 2 and the slide lever 3, however, due to the tight fit arrangement relationship between the torsion member 4 and the setting rod 22 and the sliding rod 3 of the sliding member 2, an acting force for preventing the torsion member 4 and the setting rod 22 and the sliding rod 3 of the sliding member 2 from rotating is generated, in this situation the force will be translated into a resistance preventing a change in the relative position between the setting bar 22 of the slide 2 and the slide bar 3, thereby generating a force to prevent the sliding rod 3 from sliding along the secondary rail section 122 or the primary rail section 121 of the two groove rails 12, thereby providing a positioning torsion force to prevent the sliding of the sliding member 2 relative to the base 1. In addition, during the sliding process of the sliding member 2 relative to the base 1, the positioning torsion can be changed according to the sum of the relative rotation amount between the torsion member 4 and the setting rod 22 and the sliding rod 3 when the sliding member 2 slides, thereby achieving the purpose of providing variable positioning torsion on the premise of simple structure.
In detail, in the present embodiment, since the tail end sliding rod 51 of the sliding frame 5 having the one sliding rod 3 can also slide in the secondary rail sections 122 of the two concave rails 12, the sliding frame 5 can be driven to rotate by the movement of the tail end sliding rod 51, so that the one sliding rod 3 most far away from the sliding member 2 can also rotate relative to the corresponding torsion member 4, thereby increasing the adjustability of the positioning torsion, and the sliding frame 5 can also increase the stability of the hinge 100 during operation.
It should be noted that the sum of the relative rotation amounts can be adjusted and controlled by adjusting the extending path of the secondary rail section 122 or the primary rail section 121 of the groove rail 12, thereby adjusting the magnitude of the positioning torque generated by the sliding member 2 at different positions relative to the base 1. In addition, the tightness degree between the torsion member 4 and the setting rod 22 and the sliding rods 3 can be adjusted, and the size of the torsion member 4 can be adjusted to further adjust the magnitude of the positioning torsion generated by the sliding member 2 at different positions relative to the base 1.
To sum up, the utility model discloses hinge 100 passes through the recessed rail 12 of base 1 slide bar 3 with the cooperation of torsion piece 4 provides the prevention slider 2 for the gliding location torsion of base 1, and slider 2 for the gliding in-process of base 1, location torsion can be according to when slider 2 slides torsion piece 4 with set up the pole 22 and the total sum of the relative rotation volume between the slide bar 3 produces the change, borrows this under simple structure's prerequisite and reaches the purpose that provides changeable location torsion.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
