Abstract
The invention discloses a kind of key-ring, including circle body and connector, described connector one end is rotated with circle body by rotating shaft and is connected, the other end is provided with contiguous block, the contiguous block both sides are fixedly installed the projection of semiellipse shape respectively, described circle body one end is connected with the connector by rotating shaft, and the other end is provided with the groove being engaged with the connecting block structure, the cell wall of the groove both sides and is respectively arranged with the neck being engaged with the projection cube structure；The present invention has the advantages that simple to operate, easy to use.
Description
Technical field
The invention belongs to hardware technical field, and in particular to a kind of key-ring.
Background technology
At present, people will be usually enclosed in key-ring in key, and key-ring then is hung on into trousers ear by key chain
On, in order to carry, it is to avoid the loss of key；Existing key-ring is typically rolled by a metal line material and formed, and is formed overlapping
Twin nuclei, be close between two terminations of key-ring and connected key-ring circle body, in use, need first by one end
Head pulls open a low-angle, then key is fitted inside, and is formed because key-ring is rolled by metal wire rod, thus when pulling open elastic force compared with
Greatly, waste time and energy and easily nail is caused damage；To solve the above problems, a kind of key simple to operate, easy to use of exploitation
Spoon circle is necessary.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and provide a kind of key simple to operate, easy to use
Spoon circle.
The object of the present invention is achieved like this：A kind of key-ring, including circle body and connector, described connector one end lead to
Cross rotating shaft to be connected with circle body rotation, the other end is provided with contiguous block, and the contiguous block both sides are fixedly installed semiellipse shape respectively
Projection, described circle body one end is connected with the connector by rotating shaft, and the other end is provided with and the connecting block structure matches
The neck being engaged with the projection cube structure is respectively arranged with the groove of conjunction, the cell wall of the groove both sides.
The connector is 90 around the maximum angle that circle body is rotated by rotating shafto。
The circle body is the annular shape for being provided with opening, and the length of opening is identical with the length of the connector.
The width of the groove is 2mm, and the width of the contiguous block is 1.5mm, and the thickness of the projection is 0.75mm.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The present invention, by the mating connection of projection and neck, completes circle body and connector using the connected mode of projection and neck
Between connection, and then it is closed to complete circle body, and elastic force is larger when solving existing key-ring because pulling open, and wastes time and energy and easily
The problem of being caused damage to nail；
Total, the present invention has the advantages that simple to operate, easy to use.
Brief description of the drawings

Fig. 2 is the front view when present invention is opened.
Fig. 3 is the top view of concave slot structure of the present invention.
Fig. 4 is the local structural graph of connector in the present invention.
In figure：1st, circle body 11, groove 12, neck 2, connector 21, contiguous block 22, projection 3, rotating shaft.
Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4：A kind of key-ring, including circle body 1 and connector 2, described one end of connector 2 lead to
Cross rotating shaft 3 to be connected with the rotation of circle body 1, the other end is provided with contiguous block 21, the both sides of contiguous block 21 are fixedly installed half respectively
Elliptoid projection 22, described one end of circle body 1 is connected with the connector 2 by rotating shaft 3, and the other end is provided with and the connection
It is respectively arranged with and is engaged with the structure of projection 22 on the groove 11 that the structure of block 21 is engaged, the cell wall of the both sides of groove 11
Neck 12.
The connector 2 is 90 around the maximum angle that the circle body 1 is rotated by the rotating shaft 3o；The circle body 1 is
The annular shape of opening is provided with, the length of opening is identical with the length of the connector 2；The width of the groove 11 is 2mm, institute
The width for stating contiguous block 2 is 1.5mm, and the thickness of the projection 22 is 0.75mm.
The present invention is during use, when needing to open key-ring, ecto-entad pressing connector 2, makes semiellipse
The projection 22 of shape is disconnected with neck 12, and projection 22 is easy to the opening and closing of connector 2 using the structure of semiellipse shape, enters
And the connection of connector 2 and circle body 1 is disconnected, make connector 2 around the rotation of circle body 1 90 using rotating shaft 3o, the opening of circle body 1 beats
Open, that is, complete the opening of key-ring；Key-ring presses connector 2, makes the connection of the one end of connector 2 from inside to outside in closure
Projection 22 on block 21 is connected with the neck 12 in groove 11, that is, completes the connection of circle body 1 and connector 2, key-ring closure；Always
, the present invention has the advantages that simple to operate, easy to use.
The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, although with reference to above-described embodiment pair
The present invention is described in detail, it should be understood by a person of ordinary skill in the art that still can be to the specific of the present invention
Embodiment is modified or equivalent substitution, and any modification or equivalent substitution without departing from spirit and scope of the invention,
It all should cover among scope of the presently claimed invention.
