Abstract

The utility model discloses a laborsaving key -ring, including the ring body, the ring body is the opening rectangle, its open position is in a long limit of rectangle, this long limit is falld into segment and long section by the opening, set up the external screw thread on the segment, the diameter of long section is less than the diameter of other parts of ring body and sets up the internal thread at the terminal surface, long section goes up the cover and establishes the sleeve, matching the external screw's internal thread on interior setting of sleeve and the segment, telescopic one end setting and long section diameter clearance fit's bulge loop, in one end that soket head cap screw kept away from the bulge loop from the sleeve penetrates the sleeve screw with the internal thread of long section setting in the back, the sleeve lateral wall is close to bulge loop department and sets firmly first even board, and with the articulated second of first even board even board, the second even length of board is less than the first even length of board, and the second even free end of board inlays and establishes strong magnet, strong magnet can with another long limit butt actuation of ring body. Compared with the prior art, the utility model discloses simple structure need not to use very big strength just can penetrate the key and very safe.

Description

A kind of laborsaving key ring

Technical field

This utility model is related to daily life technical field, specifically related to a kind of laborsaving key ring.

Background technology

In order to prevent key landing, the quoit of common key ring is mostly closely against together, sometimes must be very laborious It could be broken into two with one's hands, sometimes also can hurt fingernail.

Content of the invention

The purpose of this utility model still overcomes the deficiencies in the prior art, provides a kind of laborsaving key ring, need not arduously Can allow its on an off, adopt the technical scheme that for this this utility model：

A kind of laborsaving key ring, including ring body it is characterised in that：Described ring body is open rectangle, and its opening is located at square One long side of shape, this long side is divided into segment and long section by opening, and segment arranges external screw thread, the diameter of long section be less than ring body its The diameter of his part simultaneously arranges setting and external screw thread cooperation on segment in female thread, sheathed sleeve in long section, sleeve in end face Female thread, one end setting of sleeve and the bulge loop of long sections of straight footpath gap cooperation, soket head cap screw is from sleeve away from bulge loop One end is penetrated and is screwed with the female thread of setting in long section after in sleeve；Sleeve lateral wall fixed first connecting plate at bulge loop, with Hinged second connecting plate of one connecting plate, the length of the second connecting plate is less than the length of the first connecting plate, and the free end of the second connecting plate is embedded strength Magnet, strong magnets can abut adhesive with another long side of ring body.

Further, another long side of ring body corresponds to position setting notch, strong magnets and the notch of strong magnets Base plane abut.

Compared with prior art, this utility model structure is simple, just key can be penetrated this without using very big strength In utility model, and will not automatic open it is ensured that safety.

Specific embodiment

Referring to accompanying drawing, a kind of laborsaving key ring, including ring body 1 it is characterised in that：Described ring body 1 is open rectangle, its Opening 11 is located at a long side of rectangle, and this long side is divided into segment 14 and long section 12 by opening 11, and segment 14 arranges external screw thread, The diameter of long section 12 is less than the diameter of ring body other parts and arranges female thread, sheathed sleeve 2, sleeve 2 in long section 12 in end face The female thread that interior setting is coordinated with external screw thread on segment, one end setting of sleeve 2 and the bulge loop 21 of long sections of straight footpath gap cooperation, one Individual soket head cap screw 13 from sleeve away from bulge loop 21 one end penetrate in sleeve 2 after screw with the female thread that arranges long section；Set Cylinder 2 side walls fixed first connecting plate 3 at bulge loop, and hinged second connecting plate 4 of the first connecting plate 3, the length of the second connecting plate 4 is less than the The length of one connecting plate, the free end of the second connecting plate is embedded strong magnets 5, and strong magnets 5 can be abutted with another long side of ring body 1 Adhesive.The position that another long side of ring body 1 corresponds to strong magnets 5 arranges notch 15, the bottom of strong magnets 5 and notch 15 Plane abuts.

Passing through during use to fold the first connecting plate and the second connecting plate makes sleeve rotatable, thus arrange from segment is outer Enter on screw thread and exit, thus opening and closing the key ring described in this utility model, when the first connecting plate and the second connecting plate exhibition Open, when strong magnets abut adhesive with another long side, sleeve cannot rotate it is ensured that safety is so that key will not be lost.
