Description

Limiting hinge

Technical Field

The utility model relates to a hinge technical field, concretely relates to spacing hinge.

Background

Tablet computer and large-screen cell-phone, in order to prevent falling and protect the screen, more and more people protect with the leather sheath, and in addition for convenient use, the leather sheath has the folding back and has the support effect, can be used to support tablet computer and large-screen cell-phone, makes things convenient for the use of tablet computer.

The existing folding leather sheath is mostly folded by hinges and forms a support by means of external resistance, but the leather sheath formed by the scheme is unstable in support, and once the support is not formed enough due to the fact that no external resistance exists, normal use of the tablet personal computer and the large-screen mobile phone is affected.

Disclosure of Invention

In order to overcome the defects and deficiencies in the prior art, the utility model aims to provide a limiting hinge.

The purpose of the utility model is realized through the following technical scheme: a limiting hinge comprises a hinge body, wherein the hinge body comprises a first blade, a second blade and a rotating shaft, the first blade is provided with a first shaft sleeve, the second blade is provided with a second shaft sleeve, one end of the rotating shaft is inserted into the first shaft sleeve and is fixedly connected with the first shaft sleeve, and the second shaft sleeve is sleeved on the rotating shaft and is rotatably arranged around the rotating shaft; the arc breach has been seted up to the one end of first axle sleeve, the one end of second blade extend have with the spacing piece of arc breach complex, the arc breach is used for the restriction the home range of spacing piece.

Preferably, the limiting hinge further comprises a hollow tube connected with the hinge body, and the rotating shaft penetrates through the second shaft sleeve and is fixedly inserted into one end of the hollow tube.

Preferably, the number of the hinge bodies is two, and the two hinge bodies are symmetrically arranged at two ends of the hollow pipe.

Preferably, the hollow pipe is provided with a yielding through hole.

Preferably, the abdicating through hole is in a long strip shape.

The beneficial effects of the utility model reside in that: the utility model discloses a spacing hinge, with pivot and first axle sleeve fixed connection, pivot and second axle sleeve rotation set up as the basis, the arc breach that again borrows the help first axle sleeve to set up cooperates with the spacing piece that the second blade extends, limits the turned angle of second axle sleeve, when the second axle sleeve rotates and reaches the maximum turned angle, the spacing piece supports and leans on the lateral wall in arc breach to limit the rotation range of second axle sleeve, reach spacing effect; be applied to folding leather sheath with traditional hinge of this spacing hinge replacement, can effectively make folding leather sheath form the support, and lean on self limit structure fixed, the steadiness is higher.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.

As shown in fig. 1 to 5, a limiting hinge comprises a hinge body, wherein the hinge body comprises a first blade 1, a second blade 2 and a rotating shaft 3, the first blade 1 is provided with a first shaft sleeve 4, the second blade 2 is provided with a second shaft sleeve 5, one end of the rotating shaft 3 is inserted into the first shaft sleeve 4 and is fixedly connected with the first shaft sleeve 4, and the second shaft sleeve 5 is sleeved on the rotating shaft 3 and is rotatably arranged around the rotating shaft 3; an arc-shaped notch 6 is formed in one end of the first shaft sleeve 4, a limiting piece 7 matched with the arc-shaped notch 6 extends from one end of the second blade 2, and the arc-shaped notch 6 is used for limiting the moving range of the limiting piece 7.

The limiting hinge is based on the fixed connection of the rotating shaft 3 and the first shaft sleeve 4 and the rotation of the rotating shaft 3 and the second shaft sleeve 5, and limits the rotation angle of the second shaft sleeve 5 by means of the matching of the arc-shaped notch 6 formed in the first shaft sleeve 4 and the limiting sheet 7 extended by the second blade 2, and when the second shaft sleeve 5 rotates to reach the maximum rotation angle, the limiting sheet 7 is abutted against the side wall of the arc-shaped notch 6, so that the rotation range of the second shaft sleeve 5 is limited, and the limiting effect is achieved; be applied to folding leather sheath with traditional hinge of this spacing hinge replacement, can effectively make folding leather sheath form the support, and lean on self limit structure fixed, the steadiness is higher.

In this embodiment, the limiting hinge further includes a hollow tube 8 connected to the hinge body, and the rotating shaft 3 penetrates through the second shaft sleeve 5 and is fixedly inserted into one end of the hollow tube 8.

By adopting the technical scheme, the position of the second shaft sleeve 5 is limited between the first shaft sleeve 4 and the hollow pipe 8, and the limiting failure caused by the separation of the limiting sheet 7 from the arc-shaped notch 6 is avoided.

In this embodiment, the number of the hinge bodies is two, and the two hinge bodies are symmetrically arranged at two ends of the hollow tube 8.

Adopt above-mentioned technical scheme, improve the steadiness of spacing hinge, more be suitable for the firm connection in folding leather sheath, prevent that folding position of folding leather sheath is not hard up.

In this embodiment, the hollow tube 8 is provided with a yielding through hole 9.

By adopting the technical scheme, when the folding leather sheath is provided with the electric wire, the electric wire can be conveniently and intensively run through the abdicating through hole 9 for wiring, the space is saved, and the wiring is more tidy.

In this embodiment, the abdicating through hole 9 is in a long strip shape.

By adopting the technical scheme, the electric wires are more convenient to arrange side by side and run through the yielding through holes 9 for wiring when the electric wires are arranged on the folding leather sheath, so that the space is saved, and the wiring is more tidy.

The above-mentioned embodiment is the utility model discloses the implementation of preferred, in addition, the utility model discloses can also realize by other modes, not deviating from the utility model discloses any obvious replacement is all within the protection scope under the prerequisite of design.
