Description

One-shaped hub

technical field

The utility model relates to an in-line hinge device, in particular to an in-line hinge device installed between an upper cover and a base of a flip-cover device for relatively opening and closing the upper cover on the base.

Background technique

The one-shaped hinge is generally installed between the upper cover and the base of the flip-top device, so that the upper cover is relatively opened and closed on the base. The one-shaped hinge includes a shaft and a bushing, and the shaft and the bushing The upper cover and the base are connected respectively, and the shaft is passed through the sleeve so that the upper cover can rotate relative to the base. The positioning device of the in-line hinge in the prior art is that the shaft rod and the periphery of the shaft sleeve are radially extended and formed with relative protrusions, and the rotation angle of the shaft rod is limited by the mutual abutment of the protrusion edges. However, the mutual The pushed bump can only limit the rotation angle of the shaft, but cannot effectively position the shaft at the desired angle, that is, it can only prevent the upper cover from over-rotating and collide with the base, but it cannot position the shaft The upper cover is indeed positioned at a closed angle relative to the base, which cannot prevent the upper cover from colliding with the base when the upper cover is relatively closed to the base.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the utility model improves the one-shaped hinge device, so that when the one-shaped hinge device is applied to flip-covered items, it can not only avoid the collision between the upper cover and the base, but also effectively secure the upper cover. position.

In order to achieve the above-mentioned purpose, the technical means adopted by the utility model is to design a kind of in-line hinge device, which includes:

A shaft sleeve, one side of which is a fixed part, the other side is a hollow sleeve and has a connecting socket part and a fitting part, and the inner wall of the socket part is axially concavely formed with at least one groove;

A shaft, one side is a fixed part, and the other side is a rod-shaped torsion part. In the socket part, and the outer diameter of the twisted part is larger than the inner diameter of the socket part, two opposite flat walls are formed on the twisted part and the periphery of the fitting end, so that two opposite arcs are formed on the periphery of the twisted part between the two flat walls , the arc part can fall into the groove of the socket part to achieve positioning.

The shaft sleeve and the base of the flipping device are fixed to each other, and the shaft rod and the upper cover of the flipping device are fixed to each other.

The utility model has the advantage that the shaft rod is positioned relative to the shaft sleeve through the arc portion of the twisted part of the shaft being fitted with the groove of the socket part of the shaft sleeve, so that the upper cover is positioned relative to the base, and because The outer diameter of the torsion part is larger than the inner diameter of the sleeve part, and the user must apply force to make the arc part escape from the groove, so that the upper cover can be effectively positioned relative to the base.

Detailed ways

Please refer to FIG. 1 , the utility model includes a shaft sleeve 10 and a shaft rod 20 .

Please refer to Fig. 2, one side of the aforementioned shaft sleeve 10 is a fixed portion 11, and the other side of the shaft sleeve 10 is a connecting sleeve portion 12 and a fitting portion 13, and the fitting portion 13 is arranged on the sleeve portion 12 and the fixing portion. Between the parts 11, the fitting part 11 and the sleeve part 12 are both hollow sleeves. The inner diameter of the socket part 12 is larger than the inner diameter of the fitting part 13, and an arc-shaped gap 14 is formed on the shaft sleeve 10 between the socket part 12 and the fitting part 13 along the side wall surface, and the socket part 12 is axially penetrated. There is an elongated notch 121. Due to the arrangement of the arc-shaped notch 14 and the elongated notch 121, although the sleeve part 12 and the fitting part 13 are connected, the inner diameter thereof can be slightly expanded outwards independently due to external force. At least one groove 122 is formed axially inwardly on the inner wall of the aforementioned socket portion 12. In this embodiment, two opposite 180-degree grooves 122 are formed on the inner wall surface of the socket portion 12 in the axial direction. Or the desired angle of relative positioning, the two grooves 122 are arranged at different relative angles.

One side of the shaft rod 20 is a fixed part 21, and the other side is a rod-shaped twisted part 22. The end of the twisted part 22 is extended to form a fitting end 23, and the twisted part 22 and the fitting end 23 are formed on the 180-degree peripheral edge There are two opposite flat walls 24, so that the peripheral edge of the torsion part 22 is located between the two flat walls 24, and two opposite arcs 221 are formed. The arcs 221 can be formed with a sleeve part 12 for reducing the torsion 22 and the sleeve 10. The lack of groove 222 in the friction area of the inner wall.

The outer diameter of the fitting end 23 of the shaft rod 20 matches the inner diameter of the fitting portion 13 of the shaft sleeve 10 , and the fitting end 23 of the shaft rod 20 is engaged in the fitting portion 13 of the shaft sleeve 10 . As shown in Fig. 3 , the twisted portion 22 passes through the sleeve portion 12, and the outer diameter of the twisted portion 22 is slightly larger than the inner diameter of the sleeve portion 12 of the bushing 10, then the sleeve portion 12 is twisted by the twisted portion 22 at the elongated notch 121. Slightly stretched, and the setting of the arc-shaped notch 14 makes the socket part 12 and the fitting part 13 partly connected, the deformation of the socket part 12 does not make the fitting part 13 deform accordingly, and the fitting part 13 and the shaft The fitting end 23 of 20 can provide greater frictional force. When the shaft 20 rotates so that the arc portion 221 of the torsion portion 22 falls into the groove 122 of the socket portion 12 of the shaft sleeve 10 to fit, the originally stretched socket portion 12 returns to its original shape, and Achieve positioning effect.

In the above-mentioned embodiment, since the two grooves 122 in the sleeve part 12 are arranged at relative 180 degrees, it can be used for flipping devices such as mobile phones to achieve the effect of lifting 180 degrees, but it depends on different usage occasions. , the two grooves 122 can be set at different relative angles according to the relative positioning angle required by the user. As shown in FIG. 5 , when used in a flip device for a computer, the fixed portion 11 of the bushing 10 is fixed to the base 30 of the flip device, and the fixed portion 21 of the shaft 20 is fixed to the upper cover 40 of the flip device. When the upper cover 40 rotates relative to the base 30, the upper cover 40 drives the shaft 20 to rotate, and when the arc portion 221 of the torsion part 22 fits with the groove 122 of the sleeve part 12 of the sleeve 10, the shaft is relatively positioned. 20, so that the upper cover 40 can be positioned when it is closed relative to the base 30, so as to prevent the upper cover 40 from hitting the base 30, and at the same time, because the outer diameter of the torsion part 22 is slightly larger than the inner diameter of the sleeve part 12 of the shaft sleeve 10, when the arc part 221 and When the grooves 122 fit together, the user must apply a large force to rotate the shaft 20 relative to the sleeve 10 , so the relative positions of the upper cover 40 and the base 30 can be effectively positioned.
