Description

A kind of key case

Technical field

The utility model relates to a kind of key case, especially the key case lost of a kind of leather sheath and key difficult drop-off.

Background technology

At present, key case mainly comprises key case body, hook portion, and the connecting portion connecting key case body and hook portion forms, key case body can use a lot of material, as leather etc., and between key case body and hook portion often through some bindiny mechanisms as key-ring, the connections such as screw and nut, original key case, after long-time use, material ageing and screw is got loose, leather sheath and the key phenomenon causing key case to use that comes off is very general, sometimes even the losses such as key loss are caused, therefore the connecting portion between key case body and hook portion needs to have higher intensity, ageing resistance, also need of course simultaneously to have aesthetic concurrently, this problems demand solves.

Utility model content

For solving the problem, the utility model provides a kind of key case, and between key case body and hook portion, arrange new bindiny mechanism, ageing resistance is high, and intensity is higher, avoids rupturing because of it losses such as the key loss caused.

For achieving the above object, the utility model adopts following technical scheme:

A kind of key case, comprise key case body, described key case body has the accommodating cavity holding key, described accommodating cavity is fitted and connected is formed by the base of two side pages, dual-side, formation openend, page top, both sides, described key case body is symmetrical arranged perforation on the both sides page of open end, arranges a detachable band, one end of described detachable band, successively through after the perforation on the page of both sides, is connected with self other end.

Wherein, described detachable band left end arranges the first through hole, right-hand member arranges the second through hole, in the middle part of described detachable band, third through-hole is set, one retaining mechanism is set, described detachable band left end is successively through after the perforation on the page of both sides, bending band two ends make described first through hole, the second through hole aligns with third through-hole, and described retaining mechanism is through locked behind above-mentioned three holes.

Wherein, the described retaining mechanism nut that is bolt and is mated.

Wherein, described first through hole, the second through hole are fixed on the same side of described third through-hole.

Wherein, described first through hole, the second through hole are fixed on the both sides of described third through-hole.

Wherein, described key case body and detachable band use there is certain thickness, flexible leather is made.

Wherein, described retaining mechanism arranges hook portion.

The beneficial effects of the utility model are: key case of the present utility model uses perforate to wear the combination of band, band and keyhole position and inclusion coincide, friction is caused to prevent key and leather sheath, screw and band press face width, utilize the elasticity of leather strap, compress, prevent loosened screw, avoid aging the getting loose of key case Long-Time Service and cause losing the problems such as key.

Detailed description of the invention

Following examples are only for the utility model example is clearly described, and the restriction not to embodiment of the present utility model.For those of ordinary skill in the field; can also make other multi-form change or variations on the basis of the following description, and these belong to the utility model spirit apparent change of drawing or variation is still among protection domain of the present utility model.

As shown in Figure 1, in key case specific embodiment of the present utility model, comprise key case body 1, described key case body 1 has the accommodating cavity holding key, described accommodating cavity is by the base 13 of two side pages, dual-side 11, 12 are fitted and connected formation, formation openend, page top, both sides, described key case body 1 is symmetrical arranged perforation 14 on the both sides page of open end, one detachable band 2 is set, described detachable band 2 one end is successively through after the perforation 14 on the page of both sides, be connected with self other end, as shown in Figure 2, described detachable band 2 left end arranges the first through hole 21, right-hand member arranges the second through hole 22, in the middle part of described detachable band, third through-hole 23 is set, one retaining mechanism 3 is set, described detachable band 2 left end is successively through after the perforation 14 on the page of both sides, bending band two ends make described first through hole 21, second through hole 22 aligns with third through-hole 23, described retaining mechanism 3 is through locked behind above-mentioned three holes, as Fig. 3, shown in Fig. 4, the nut 32 that described retaining mechanism 3 is bolt 31 and is mated, as shown in Figure 4, described retaining mechanism 3 arranges hook portion 33.It is worth mentioning that when above-mentioned three holes alignment, described first through hole, the second through hole can be fixed on the same side of described third through-hole, also the both sides of described third through-hole can be fixed on, described key case body 1 and detachable band 2 uses there is certain thickness, flexible leather is made, detachable band 2 and keyhole position and inclusion identical, cause friction to prevent key and leather sheath, screw and band press face width, utilize the elasticity of band, compress, prevent loosened screw.
