Description

A kind of coin protection box

Technical field

The utility model relates to a kind of coin protection box, relates in particular to a kind of protection box with coin anchor fitting.

Background technology

At present on coin market, for the protection of coin, be to pack coin into a transparent protection box mostly.So both ornamental, had prevented again that coin was worn in circulation storage simultaneously.For various sizes coin not of uniform size, its guard method one is the protection box of selecting corresponding size; The 2nd, the foaming liner that uses various sizes to differ in a larger protection box, embeds wherein coin so that coin and protection box are fixed.For the first way, because coin size of all times is multifarious, in order to protect these coins need to produce the box of a variety of specifications.And the box of a kind of specification of every production just need to be opened the corresponding mould of system, so productive costs is higher.For the user, often collecting a kind of coin of size, just need to select corresponding coin box, is also an inconvenience.Again because box not of uniform size is also not easy to the unified keeping of piling up.The second way, because foaming liner has certain elasticity, it no doubt can be realized coin and protection box are fixed, but owing to often fixing one piece of coin, just needs to find, consume roughly suitable liner of a size, both inconveniently also causes waste simultaneously.Moreover, coin is embedded in foaming liner, make the side of coin invisible, affected user and appreciated for the integral body of this piece of coin.

Utility model content

The purpose of this utility model is; improve the drawback that existing coin protection box exists; provide a kind of and can regulate very easily fixed measure within the scope of certain size, without coin one box or coin one pad, and do not affect the protection box that user appreciates coin on the whole.

Coin protection box is comprised of lower box and upper cover, is at least provided with two chutes in lower box, is equipped with corresponding slide block in chute.The upper surface of slide block is provided with thread groove.In box, be also provided with a control loop, the lower surface of control loop is provided with the screw thread matching with thread groove on slide block.Rotation control loop can make slide block move along the direction of chute.Claimed coin is placed in to box, then rotates control loop, slide block Xiang He center is moved until touch coin, thereby coin is fixed, then cover upper cover.Control loop can design and become round table-likely, and lateral surface and chute clamping, in case it comes off.When coin need be taken out, only need contrarotation control loop, slide block is outwards moved, unclamp coin, can take out.In certain range of sizes, by the adjustable fixed measure of rotation control loop.Realize with a protection box and can carry out protection to the coin of plurality of specifications.For user provides a great convenience.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Embodiment material is transparent plastic material.

Embodiment mono-

Referring to Fig. 1, described lower box 1 is rectangle, the convex tendons 13 that have 4 groups of protrusions suitable for reading, and inside is provided with from four angles the chute 11 extending to center position respectively, has buckle face 12 on chute 11.

With reference to Fig. 2, at the interior slide block 3 that is equipped with respectively of chute 11.The upper surface of slide block 3 is provided with thread groove 31.

With reference to Fig. 3, Fig. 4, Fig. 5, above slide block 3, be provided with a control loop 4, there is the screw thread 41 matching with thread groove 31 on slide block 3 control loop 4 lower surfaces.Control loop 4 profiles are round platform, and its side is circular conical surface 42.

With reference to Fig. 6 and Fig. 7, slide block 3 is placed in chute 11, and the screw thread 41 of control loop is embedded in the thread groove 31 of slide block 3, and the outside circular conical surface 42 of control loop 4 is embedded in the buckle face 12 of chute 11.When having coin to need protection, this coin is placed in to lower box 1, then rotate control loop 4; the screw thread 41 of control loop 4 lower ends drives four slide blocks 3 to move to center position along chute 11 by thread groove 31 simultaneously; until this coin is fixed, then cover upper cover 2, complete coin and enter box protection.In the time of need to taking out, open upper cover 2, contrarotation control loop 4, makes slide block 3 outwards move along chute 11, unclamps coin, can take out.Upper cover 2 is interior fluted 21, during assembling, coordinates with the convex tendon 13 on lower box 1, guarantees that upper cover is unlikely to come off.

Embodiment bis-

With reference to Fig. 8, Fig. 9, its profile of the utility model is not limited to rectangle, also can do circular other shapes such as grade.Its guard method is identical with embodiment mono-.
