DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
As shown in FIG. 1 through FIG. 8, the communication box according to a preferred embodiment of the present invention comprises a box body 10 and a box lid 20. The box body 10 has an accommodation space therein. The box lid 20 comprises a lid body 21 and two engaging members 22, as shown in FIG. 2.
The two engaging members 22 are pivotally connected two opposing sides of the lid body 21, respectively. The two engaging members 22 are rotatable relative to the lid body 21. Upper and lower ends of the two engaging members 22 are connected to the box body 10.
Each engaging member 22 comprises a main body 221. The main body 221 has a pivot hole 222 thereon. Left and right sides of the lid body 21 each have a pivot 201. The pivot 201 is inserted in the pivot hole 222 of the relative engaging member 22. In this embodiment, the pivot hole 222 has an axial opening facing the lid body 21. The pivot hole 222 has a C-shaped cross-section. In this way, the two engaging members 22 can be coupled to the pivot 201 with ease. The pivot 201 is aligned with the axial opening of the pivot hole 222 and then pushed into the pivot hole 222. Preferably, the engaging member 22 has two spaced pivot holes 222 in an axial direction. The lid body 21 has two mating pivots 201 at each of the left and right sides thereof.
For the upper and lower ends of the two engaging members 22 to be coupled to the box body 10 with ease, the main body 221 has an upper end formed with two spaced auxiliary engaging hooks 223. The two auxiliary engaging hooks are located between the two pivot holes 222 at the same side. Two opposing sides of the box body 10 each have two spaced auxiliary engaging recesses 11 which are located between the two pivots 201 at the same side. The auxiliary engaging hooks 223 extend from the upper end of the main body 221. As shown in FIG. 8, the auxiliary engaging hooks 223 are engaged in the auxiliary engaging recesses 11. The main body 221 has a lower end formed with a resilient engaging hook 224. The resilient engaging hook 224 has a U-shaped configuration, and comprises a press portion 225 and a connection portion 226. The press portion 225 is integrally formed with the connection portion 226. The press portion 225 has a protrusion 227 protruding downward from a lower end thereof. The two opposing sides of the box body 10 each has a first receiving recess 12 and an engaging groove 13 underneath the first receiving recess 12. The resilient engaging hook 224 is received in the first receiving recess 12. The press portion 225 is exposed out of the box body 10, and the protrusion 227 is engaged in the engaging groove 13. Thus, when one of the engaging members 22 is disengaged, the lid body 21 of the box lid 20 can be opened upward with the other engaging member 22 as a pivot. This won't influence the connection of the other engaged engaging member 22 and the box body 10.
In this embodiment, the two sides of the box body 10 each have an accommodation chamber 14 to accommodate the main body 221 of the relative engaging member 22. When the box lid 20 is locked to the box body 10, the two engaging members 22 are received in the two sides of the box body 10, so that the communication box of the present invention is compact and small in size. The outer surface of the communication box is smooth, which is beneficial for arrangement and storage.
When in use, the box lid 20 is placed on the box body 10 and the two engaging members 22 are engaged with the box body 10 so as to achieve connection of the box lid 20 and the box body 10. As shown in FIG. 3, the box lid 20 and the box body 10 are in an engaged state. The lid body 21 is disposed on top of the box body 10. The two engaging members 22 are engaged with the box body 10.
When the user wants to open the box lid 20, one of the engaging members 22 can be disengaged from the box body 10. The press portion 225 of the resilient engaging hook 224 is pressed upward to release the protrusion 227 from the box body 10, and the resilient engaging hook 224 is disengaged from the first receiving recess 12. After that, the resilient engaging hook 224 is turned upward to release the auxiliary engaging hooks 223 from the auxiliary engaging recesses 11, so that the lid body 21 can be opened with the other engaged engaging member 22 and the relative pivot 201 as the pivot, as shown in FIG. 6. The two engaging members 22 can be disengaged from the box body 10, such that the box lid 20 is detached from the box body 10, as shown in FIG. 7.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
