Abstract

The utility model relates to a pivoting device, which comprises a pivoting element, a fixing element, an open hole part, and a convex part, wherein the pivoting element is provided with two opposite side edges which are respectively and convexly provided with a first pivoting rod and a second pivoting rod; the fixing element is provided with two corresponding pivoting surfaces which are respectively provided with an open hole and a grooving, wherein the open hole is used for containing and pivoting the first pivoting rod, and the grooving comprises a chute part for inserting and sliding the second pivoting rod; the open hole part is used for containing and pivoting the second pivoting rod; the convex part is positioned between the chute part and the open hole part. The second pivoting rod is pivoted behind the open hole part from the chute part through the convex part, is blocked and stopped by the convex part, and is limited to the open hole part. Thereby, the pivoting element and the fixing element have firm combination and easy assembly and disassembly.

Description

Pivot joint

Technical field

The utility model is about a kind of pivot joint, refers in particular to that a kind of easy assembling is disassembled and in conjunction with firm pivot joint.

Background technique

All being provided with Pivot component on many now electronic equipments, generally promptly is to be connected in the pivot joint mode between the battery protecting cover of electronic equipment and housing for example.The design of Pivot component is except that considering that structure simplifies as far as possible saving the cost, if the convenience that process is disassembled in linking steady character can consider that its group is established the time and assembling is then even more ideal.Easy more assembly and disassembly only usually, the low more and easy disengaging of the reliability of its combination under the winding state.

The model utility content

The purpose of this utility model is to provide a kind of pivot joint.

For achieving the above object, the pivot joint that the utility model provides comprises:

One pivot member has two opposition side limits and is convexly equipped with one first hinged arm and one second hinged arm respectively;

One fixed block, have two relative pivot joint faces and offer a perforate and the fluting that this first hinged arm of confession is installed with pivot respectively, this fluting comprises a slide groove portion of sliding for this second hinged arm inserts, and supplies this second hinged arm to be installed with the aperture portion of pivot, and a jut between this slide groove portion and aperture portion, make this second hinged arm after this slide groove portion is hubbed at this aperture portion by this jut, will be subjected to this jut block and arrest and be limited to this aperture portion.

Wherein the perforate that supplies this first hinged arm to be installed with pivot is a circular hole.

Wherein this aperture portion of this fluting is a circular hole.

Wherein this of this fixed block two relative pivot joint faces are positioned at a side, and this slide groove portion has one and is opened in an edge of this side and the opening that inserts for this second hinged arm.

Wherein this jut comprises a pair of summit projection toward each other.

By the above-mentioned pivot joint that the utility model provides, its simple structure and assembling, dismounting are all easy, and be also firm and be difficult for breaking away under the winding user mode, and can be widely used in the various designs that need Pivot component.

Embodiment

Technology contents of the present utility model and effect will elaborate in following conjunction with figs. and preferred embodiment.

As shown in Figure 1 to Figure 3, the preferred embodiment of the utility model pivot joint mainly comprises a pivot member 1 and a fixed block 2.Pivot member 1 generally is a long rectangle block, is positioned at its length to the two opposition side limits 11 at two ends and have, and is convexly equipped with one first hinged arm 111 and one second hinged arm 112 respectively from dual-side 11.

Fixed block 2 is that the housing with a portable electronic devices (figure a do not show) side is an example in the present embodiment, it forms a long rectangular recess 22 in a side 21, and form two relative pivot joint faces 23 to both sides in these side 21 respective slot 22 length, wherein a pivot joint face 23 is offered a perforate 24 that can be installed with pivot for first hinged arm 111 of pivot member 1 near rear side, and 23 in another pivot joint face is offered a fluting 25 along the vertical direction.Fixed block 2 is to be made of plastics in this example, and so other suitable pliability material is also applicable.

Fluting 25 comprises one and can insert for second hinged arm 112 of pivot member 1 and the slide groove portion of sliding 251, is installed with the circle hole shape aperture portion 252 of pivot for second hinged arm 112, and a jut 253 between slide groove portion 251 and aperture portion 252.Slide groove portion 251 has one and is opened in side 21 apical margins and the opening 254 that inserts for second hinged arm 112, and is long rectangle from opening 254 and extends downwards.253 of juts comprise and a pair ofly are positioned at slide groove portion 251 and aperture portion 252 intersections and its summit triangular bump 255 toward each other in the present embodiment, and the gap width between two projections, 255 summits, make second hinged arm 112 from slide groove portion 251 by jut 253 when aperture portion 252 moves, must compress two projections 255 earlier slightly is out of shape it and after gap, projection 255 summit slightly enlarges, begins to such an extent that enter aperture portion 252 by this gap.Otherwise, when second hinged arm 112 is placed in aperture portion 252, will be subjected to two projections, 255 blocks and arrests and to be limited to aperture portion 252, so must compress earlier equally after two projections 255 slightly are out of shape it, second hinged arm 112 begins to such an extent that enter slide groove portion 251 by two projections, 255 gaps.

Cooperate Fig. 4, shown in Figure 5, pivot member 1 is assembled in the process of fixed block 2, be that first first hinged arm 111 with pivot member 1 plugs the perforate 24 that is articulated in fixed block 2 one sides pivot joint face 23, then second hinged arm 112 of pivot member 1 is inserted and moves to jut 253 along slide groove portion 251 from the opening 254 of slide groove portion 251, after further passing jut 253 as described above, the first hinged arm ccontaining aperture portion 252 that is articulated in of 111 beginning, make pivot member 1 relative fixed part 2 and pivoting, and limit the unlikely aperture portion 252 that breaks away from easily because of second hinged arm 112 is arrested by jut 253.

The foregoing description only is to give an example for convenience of description, and the interest field that the utility model is advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
