Detailed description of the invention

Below in conjunction with the accompanying drawings, a detailed description of the invention of the present utility model is described in detail, it is to be understood that this The protection domain of utility model is not limited by detailed description of the invention.

The plastic box of this utility model adjustable volume as depicted in figs. 1 and 2, including upper box 1 and lower box 2, institute Stating upper box 1 and be rectangular configuration with lower box 2, and made by plastic material, the height of described upper box 1 is less than lower box The height of 2, the outside of lower box 2 is close in the medial wall in outside and described upper box 1 that described upper box 1 is set in lower box 2 Wall, described upper box 1 along lower box about 2 sliding, can change the volume of Turnover Box, and between upper box 1 and lower box 2 Be provided with locking mechanism, it is possible to make Turnover Box stable be maintained at a certain volume conditions.

As depicted in figs. 1 and 2, four lateral walls of described lower box 2 are provided with the fixed guide fixed column 21 of projection, and Being provided with two on each sidewall, the relative fixed guide fixed column 21 on two sidewalls is in being correspondingly arranged, and described guiding is fixed Post 21 uniform intervals along the side sidewall of the short transverse of lower box 2 is provided with multiple gear groove 211, fixed guide fixed column 21 Being provided with one on outer surface or more than one has resilient locking boss 212, preferably locking boss 212 is arranged on guiding The top of fixing post 21, the upper and lower both sides of the corresponding glide direction of locking chute 13 are arc transition simultaneously, preferably lock boss 212 is semi-cylindrical；The corresponding fixed guide fixed column 21 of described upper box 1 is provided with guide chute 11, and fixed guide fixed column 21 is embedded Guide chute 11 is interior and can carry out sliding, and the corresponding fixed guide fixed column 21 of described upper box 1 is provided with the side of gear groove 211 and arranges Having locking chute 13, in this locking chute 13, sliding is provided with snap close 3, and described guide chute 11 offers one and locking chute The lockhole 111 that 13 are connected, during preferential Turnover Box contraction state, when i.e. upper box 1 is slid onto the bottom of lower box 2, lockhole 111 connections guide the gear groove 211 of locking chute 13 and bottom；Described guide chute 11 extends along direction uniform intervals and sets Being equipped with multiple lock opening 112 matched with locking boss 212, lock opening 112 respective notch groove 211 is arranged, and i.e. locks When boss 212 is embedded into lock opening 112, described gear groove 211 aligns with lockhole 111, and the tapered end 31 of snap close 3 can pass Lockhole 111 inserts gear groove 211 and realizes locking.

As shown in Figure 3 and Figure 4, a locking chute 13 at least sidewall being provided with semi-cylindrical fixture block 131, snap close 3 is right Answering fixture block 131 to be provided with the resilient fixed strip 32 of tool, on fixed strip 32, uniform intervals is provided with and multiple matches with fixture block 131 Bayonet socket 321, snap close 3 locking chute 13 in sliding, it is possible to realize the cooperation of fixture block 131 and different bayonet sockets 321 so that lock Detain 3 stable being maintained to lock or released state；It is provided with positive stop 132 on a sidewall of locking chute 13 simultaneously, should Positive stop 132 is it can be avoided that snap close 3 departs from locking chute 13 in slipping.

As shown in Figure 4, snap close 3 includes lock body, and the front end of lock body is provided with tapered end 31, and the front surface of lock body is provided with shifting block 33, fixed strip 32 is one-body molded with lock body, is provided with breach between fixed strip 32 and lock body, by the setting of this breach, fixing Bar 32 has certain elasticity, it is possible to deform upon to a certain extent；Operator moves with the hand snap close 3, due to card by shifting block 33 The cambered surface of block 131 is arranged, and during moving with the hand, fixture block 131 can make fixed strip 32 that elastic deformation occurs, thus fixture block 131 can Embed bayonet socket 321 easily or depart from bayonet socket 321.

Further, the lateral wall of described lower box 2 is provided with convex tendon 22, described top box along the glide direction of upper box 1 The medial wall correspondence convex tendon 22 of body 1 is provided with groove 12, and convex tendon 22 is embedded in groove 12.

The use of plastic box:

1. the guide chute of upper box is directed at the fixed guide fixed column of lower box firmly toward being pushed down into, it is achieved upper box with under The combination of casing；

2. when upper box and lower box are adjusted, noting holding the catch in released state, tapered end departs from lockhole, thus Firmly it is pulled up or compresses downwards, stretching or be compressed to applicable height, making locking boss be embedded in lock opening, Then sliding snap close, makes tapered end pass lockhole and inserts in gear groove, makes fixture block embed in bayonet socket, it is achieved upper box and nowel simultaneously The positive lock of body.

Compared with prior art, this utility model is simple and reasonable, it is possible to change the volume of Turnover Box easily；Pass through Upper box is set in the outside of lower box and can carry out sliding, by upper box upwards sliding, adds the height of casing, from And add the volume of Turnover Box；The downward sliding of upper box, upper box is disposed entirely within the outside of lower box, thus little reduces Volume, conveniently transports and deposits；Inserted in different gear groove through locking by snap close, it is possible to the case that makes to socialize presents different rule Lattice, and upper box can lock reliably with lower box；Lock opening respective notch groove is arranged simultaneously, is embedded by locking boss In lock opening, snap close card sets gear groove and matches, and two kinds of locking mechanisms improve the effect of upper box and lower box locking.

Only embodiment of the present utility model disclosed above, but, this utility model is not limited to this, any ability What the technical staff in territory can think change all should fall into protection domain of the present utility model.
