Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to fig. 3, the present invention provides an embodiment: a portable file for information technology consultation service comprises three cladding shells 1, wherein the upper surface and the lower surface of a cladding shell 1 positioned in the middle of the three cladding shells 1, the surface of a cladding shell 1 positioned above and the upper surface of a cladding shell 1 positioned below are respectively provided with a storage chute 10, an extension shell 2 is movably arranged between the cladding shell 1 and an adjacent cladding shell 1, the upper surface and the lower surface of the extension shell 2 are respectively provided with a positioning groove 9, the upper end and the lower end of the extension shell 2 are movably arranged at the inner side of the storage chutes 10, a tension spring 7 is arranged between the positioning groove 9 and the storage chute 10, two ends of the tension spring 7 are fixedly connected with the inner side surface of the storage chute 10 and the inner side end surface of the positioning groove 9, wherein, a plurality of anti-falling convex blocks 6 are uniformly and fixedly arranged on the inner wall of one side of the two coating shells 1, and a plurality of positioning grooves 5 are arranged on the inner wall of the other side.

Further, the material of cladding casing 1 and extension casing 2 is PVC plastics, and cladding casing 1 and extension casing 2 are all through integration injection moulding, and cladding casing 1 and extension casing 2 of PVC plastics material have sufficient hardness and toughness, can not appear easily damaging or fracture, guarantee life.

Furthermore, one end of one of the cladding shell 1 is provided with an inserting lock cylinder 3, the other end of the cladding shell 1 is provided with a lock catch 4, and after the inserting lock cylinder 3 is connected with the lock catch 4, the folder can be closed, the folder cannot be opened easily, and the internal files cannot fall off.

Further, one side of the anti-falling convex block 6 is completely attached to the inner wall of the coating shell 1 and the inner wall of the coating shell 1 attached to the coating shell 1, the anti-falling convex block 6 and the coating shell 1 are integrally injection-molded, and parts after the integral injection molding are stably connected and have high mechanical strength, so that the parts cannot easily fall off.

Further, the upper and lower end that extends casing 2 is located intermediate position department and all is provided with limit slide 8,

limit slide

8 and 1 sliding connection of cladding casing, and coarse line can be guaranteed to prevent dropping protruding piece 6 and peg graft and can not separate easily behind constant head tank 5 inside both, further guarantees the stability after the file folder is closed.

Further, the inboard surface of constant head tank 5 all is provided with coarse line with the surface of the protruding piece 6 of preventing falling, and the size of constant head tank 5 is unanimous with the overall dimension of the protruding piece 6 of preventing falling, and coarse line can guarantee that both can not separate easily after the protruding piece 6 of preventing falling is pegged graft in constant head tank 5 is inside, further guarantees the stability after the file closure.

The working principle is as follows: when the folder is used, the bottom edge of a file to be clamped is placed above the anti-falling convex block 6 on the inner wall of the coating shell 1 positioned at the lowest part, then the coating shell 1 at the highest part is pulled upwards, so that the extension shell 2 which is originally positioned between two adjacent coating shells 1 is exposed after the coating shell 1 is pulled, the distance between the two adjacent coating shells 1 is increased, the unfolding area of the whole folder is increased at the moment until the unfolded area can coat the file to be clamped, the folder is closed at the moment, the inserting lock cylinder 3 at one end of the middle coating shell 1 is inserted into the lock catch 4 at the other end to realize locking, the anti-falling convex blocks 6 on the inner walls of the two coating shells 1 at the upper and lower parts are smoothly clamped into the positioning groove 5 at the inner side, and the file is further locked after being closed, the folder is prevented from being opened by itself, the whole folder can be retracted and stored, the size and the occupied space of the folder are effectively reduced, and convenience is brought to users to carry the folder.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
