Abstract
The utility model discloses a rotary limiting component. The rotary limiting component comprises a fixing plate and a rotating plate which are parallel to each other, wherein one side of the fixing plate opposite to the rotating plate is provided with a counter bore and an arc chute which surrounds outer side of the counter bore; two ends of the arc chute are provided with circular through holes; one side of the rotating plate opposite to the fixing plate is provided with a positioning boss and a limiting ball; the limiting ball is connected with the rotating plate through a spring; the fixing plate is attached to the rotating plate and compresses the spring; the positioning boss stretches into the counter bore; when the rotating plate rotates relative to the fixing plate, the limiting ball slides in the arc-shaped chute; and when the limiting ball slips in any one circular through hole, the fixing plate blocks the rotating plate so as to prevent the rotating plate from rotating. The rotary limiting component has a simple structure, is reasonable in concept and easy to arrange and occupies small space.
Description
Technical field
The utility model relates to the mechanical rotation structure, is specifically related to a kind of rotary spacing assembly.
Background technology
Our the frequent printer that uses has top cover in daily life, the tool box has cover plate, similar with it other cover plate, and its right ends links to each other with main body through hinged mode, in the time of need opening cover plate, pulls cover plate with hand and makes its rotation.But these cover plates are not provided with position-limit mechanism usually, when rotateing in place, need support with hand, otherwise cover plate can close automatically always, are inconvenient to very much operate.
The utility model content
The purpose of the utility model provides a kind of rotary spacing assembly that is arranged between stationary body and the rotating main body, when the driven rotary main body turns to opening or closure state, can be blocked firmly, must just can pull rotating main body by external force and rotate.
For this reason, a kind of rotary spacing assembly that the utility model provided comprises fixed head and swivel plate; Both laterally arrange; One side of the relative swivel plate of said fixed head is provided with heavy stand hole and the arc chute outside the heavy stand hole, and the two ends of said arc chute have manhole, and a side of said swivel plate relative fixed plate is provided with positioning round table and spacing ball; Said spacing ball links to each other with swivel plate through spring; Said fixed head and swivel plate are drawn close and are compressed spring, leave gap L between fixed head and the swivel plate, and positioning round table stretches in the heavy stand hole; When swivel plate relative fixed plate rotated, spacing ball slided in arc chute, and in the time of in spacing ball is slipped to wherein any manhole, fixed head blocks swivel plate to prevent that swivel plate from rotating.
The rotary spacing assembly is arranged between stationary body and the rotating main body, and fixed head both can be wholely set with stationary body, also can link to each other with stationary body through bolt; Swivel plate both can be wholely set with rotating main body, also can link to each other with rotating main body through bolt, thereby rotate with swivel plate.
A side that deviates from fixed head of swivel plate is provided with cylinder, and said spring is fixed in the said cylindrical cavity away from an end of spacing ball.Cylinder through independent setting is used for fixing spring, and enough spatial accommodations are arranged when guaranteeing length of spring compressed, thereby reduces the thickness of swivel plate, conserve space, optimizes distribution.
As preferably, the angle of two said manhole axis and heavy stand axially bored line is 105 ± 10 °, to adapt to the rotational angle requirement of most stationary bodies and rotating main body.
Beneficial effect: between stationary body and rotating main body, set up rotary stopper mechanism; When rotating main body turns to extreme position; Spacing ball is slipped in the manhole; Thereby prevent that effectively rotating main body is rotated further, must just can pull rotary body by external force, have simple in structure, reasonable idea, take up room little, be easy to characteristics such as layout.

Fig. 2 is the sketch map that fixed head separates with swivel plate.
Fig. 3 is the stereogram of Fig. 2.
Fig. 4 is the application sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1---a kind of rotary spacing assembly shown in Figure 3, to form by fixed head 1, swivel plate 2, spring 3 and spacing ball 4, fixed head 1 laterally arranges with swivel plate 2.One side of the relative swivel plate of fixed head 1 is provided with heavy stand hole 1a and arc chute 1b, and arc chute 1b is outside the 1a of heavy stand hole, and the two ends of arc chute 1b have manhole 1c.One side of swivel plate 2 relative fixed plates is provided with positioning round table 2a and spacing ball 4, and positioning round table 2a stretches in the 1a of heavy stand hole with the corresponding setting of heavy stand hole 1a, positioning round table 2a, and is spacing to swivel plate 2, makes the axis rotation of swivel plate 2 around positioning round table 2a.Spacing ball 4 links to each other with swivel plate 2 through spring 3.Fixed head 1 is drawn close with swivel plate 2 and is compressed spring 3, leaves gap L between fixed head 1 and the swivel plate 2, can freely rotate between the two with assurance, and spacing ball 4 rotates flexibly simultaneously.When swivel plate 2 relative fixed plates 1 rotated, spacing ball 4 slided in arc chute 1b, and in the time of in spacing ball 4 is slipped to wherein any manhole 1c, fixed head 1 blocks swivel plate 2 to prevent that swivel plate 2 from rotating.Two manhole 1c are two extreme positions of spacing ball 4 slips.
Be to reduce the thickness of swivel plate 2, in the side that deviates from fixed head of swivel plate 2 cylinder 2b is set, an end of spring 3 links to each other with spacing ball 4, the other end of spring 3 is fixed in the cavity of cylinder 2b.Also can be, increase the thickness of swivel plate 2, the cavity that will hold spring 3 be arranged in the swivel plate 2.Like Fig. 3, the angle of the axis of two manhole 1c and heavy stand hole 1a axis is preferably 105 ± 10 °, so that rotary body 2 rotates to suitable height when opening, also other angle can be set as required.
In conjunction with Fig. 1---Fig. 4 can know that the rotary spacing assembly is arranged between stationary body 5 and the rotating main body 6, and a kind of rotary spacing assembly of the left and right sides is symmetrical set.Fixed head 1 is fixed on the stationary body 5 (like printer, tool box etc.) through journal stirrup is installed; Swivel plate 2 is fixed on the rotating main body 6 (like printer top cover, instrument case lid etc.) through journal stirrup is installed; When rotating main body 6 relative fixed main bodys 5 are rotated; Spacing ball 4 slides in arc chute 1b, and when rotating main body 6 is in when opening or closing state, thereby spacing ball 4 is slipped to respectively in one of them manhole 1c rotating main body 6 is blocked.The spacing point of opening and the spacing point of closed condition of two corresponding a kind of rotary spacing assemblies of manhole 1c difference are opened or the spacing point of closed condition when spacing ball 4 rotates to, and rotating main body 6 is blocked firmly.
