Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples.

As shown in fig. 1 and 2, the right-angle hinge 2 of the embodiment of the present invention is an injection molding member formed in one piece, and includes two hollow right-angle hinge plates 22 connected together through a flexible belt 21, the cross section of the right-angle hinge plate 22 has a slot 221 with a U-shaped opening, the slot 221 of the two right-angle hinge plates 22 is arranged at a right angle, and a slot wall through hole 222 penetrating through the slot wall is provided on the right-angle hinge plate 22.

As shown in fig. 1, friction lines 2211 are further disposed on the inner side of the slot wall of the insertion slot 221. Referring to fig. 4, when the two enclosing plates 1 are connected by the right-angle hinge 2, the vertical side portions of the enclosing plates 1 are inserted into the insertion grooves 221, so that the friction force between the contact surfaces can be increased, and the connection strength can be improved.

As shown in fig. 2, in the cross section of the right-angle hinge plate 22, the two groove walls of the insertion groove 221 are optimally designed to have different heights, and when the vertical side portion of the surrounding plate 1 is inserted into the insertion groove 221, the high groove wall plays a role in guiding the vertical side portion of the surrounding plate, so that the vertical side portion of the surrounding plate is convenient to insert; further, the outer slot wall is higher than the inner slot wall. Obviously, it is not limited to the manner in which the heights of the two groove walls of the insertion groove 221 are different. The height of the two walls of the slot 221 may be the same.

As shown in fig. 2, wherein the flexible strip 21 is arranged inside the right-angled corner. The right-angled corner outer side is provided with the transition circular arc, so that the assembly and disassembly safety can be improved, and the hand injury by the edge can be avoided. The two right-angle hinge plates 22 are provided with a tooth groove structure 223 at the butt joint of the right-angle corners, and the tooth groove structure 223 comprises teeth and grooves which are matched with each other, so that the connection strength is improved, and a certain sealing effect is achieved.

Among them, the flexible belt 21 is preferably an elastic rubber belt such as TPU (Thermoplastic polyurethanes, named as Thermoplastic polyurethane elastomer rubber). The right-angle hinge plate 22 is a rigid plastic plate, is made of the same material as the enclosing plate 1, and is preferably made of an ABS material or a PP material.

Referring to fig. 4 and 5, the bounding wall case is enclosed by a plurality of bounding walls 1, is preceding bounding wall, back bounding wall, left bounding wall and right bounding wall respectively, and the vertical limit portion of each bounding wall 1 is provided with the bounding wall through-hole (not specifically illustrated in the figure), at the four corners of bounding wall case, passes through between the adjacent bounding wall 1 the utility model discloses right angle hinge 2 and threaded fastener 4 of embodiment connect. Wherein, the enclosing plate box shown in the figure is a foldable enclosing plate box, two enclosing plates which are opposite in position are foldable enclosing plates, namely a left enclosing plate and a right enclosing plate are both foldable enclosing plates; or the front coaming and the rear coaming are both folding coamings; the folding boarding comprises two folding plates 11 connected through a straight angle hinge 3 and a threaded fastener 4, and the vertical edge parts of the folding plates 11 are provided with folding plate through holes (not specifically shown in the figure). Further, right angle hinge 2 is microscler component, and is highly unanimous with bounding wall 1, only can realize the connection of adjacent bounding wall 1 with a right angle hinge 2 in the bight of bounding wall case for the equipment of bounding wall case is convenient quick with the dismantlement. When the coaming box is used, as shown in fig. 4, the coaming is unfolded, and the product is placed in the coaming box, so that the coaming box can be used for packaging, transferring, transporting or storing the product.
