Referring to fig. 1, a perspective view of a container 100 according to the present invention is shown. The container 100 includes a base 110, a pair of opposing short side panels 120, and a pair of opposing long side panels 130. Two pairs of opposing side panels 120 and 130 are foldable relative to the base 110, for example, the two pairs of side panels 120 and 130 are hinged to four edges of the base 110. When the side panels 120 and 130 are folded relative to the base 110, the epicyclic container 100 is in a stowed condition and when the side panels 120 and 130 are erected relative to the base 110, the epicyclic container 100 is in a deployed condition. In the embodiment of fig. 1, the container 100 further includes a cover panel 140, the cover panel 140 being hingedly connected to one of the side panels, such as the upper edge of the side panel 130. It should be understood that the lid 140 of the container 100 may not be hinged or otherwise connected to either side panel, but rather may be placed over the container 100 to close the opening when desired.
The cover panel 140 and the upstanding side panel need to be locked to each other when the container 100 is in use to prevent the cover panel 140 from accidentally falling, and the container 100 is therefore provided with locking formations at the adjacent edges of the cover panel 140 and the adjacent side panel. In addition, adjacent upstanding side panels also need to be locked to one another to prevent accidental folding of the side panels, and thus the container 100 may also be provided with locking structure at the adjacent edges of the adjacent side panels. The section in which the locking structure is provided is broken away in the perspective view in fig. 2. Fig. 2A and 2B show enlarged views of cut-away portions of the locking member in the locked state and the unlocked state, respectively.
As shown in fig. 2A, the cover plate 140 is provided at lateral edges adjacent to the side plates 120 with cover plate lock receiving parts 141, and the cover plate lock receiving parts 141 receive the cover plate locks 150. The cover lock 150 includes a lock operation part 152 and a lock stopper 151, and the lock operation part 152 extends upward from the lock stopper 151. Specifically, as shown in fig. 2A, the locking member operating part 152 and the locking member stopper 151 may be integrally formed, with the locking member operating part 152 being located above the locking member stopper 151. As can also be seen from the figure, the right end of the lock member stopper portion 151 extends farther rightward with respect to the right end of the lock member operating portion 152. Accordingly, the cover-plate lock accommodating portion 141 has an operating portion opening 1411 located above the top of the lock operating portion 152 and a stopper opening 1412 located laterally, specifically on the right side in the drawing, of the lock stopper 151.
The lock member operating portion 152 is accessible through the operating portion opening 1411, thereby performing locking and unlocking operations on the cover plate lock 150. The dimension of the operation portion opening 1411 in the left-right direction is larger than the dimension of the locking member operation portion 152 in that direction, so that the locking member operation portion 152 can move in the left-right direction within the operation portion opening 1411. The locking element operating portion 152 is provided with a textured top surface to facilitate operation thereof. The locking member blocking portion 151 may extend rightward from the blocking portion opening 1412 to be engaged with the side plate limiting portion 121, so that the side plate limiting portion 121 limits the locking member blocking portion 151 and the cover plate 140 to move upward relative to the side plate 120. The side plate stopper 121 is located at the top edge of the side plate 120. Specifically, as shown in the drawing, a cavity with an upward opening is formed on the top edge of the side plate 120, and a cavity facing leftward is formed at the right end of the cavity, and the cavity forms a side plate stopper 121. When the cover panel 140 is closed in place, the cover panel lock receiving portion 141 is located in a cavity opened upward on the top edge of the side panel 120, and when the lock blocking portion 151 protrudes rightward, it enters the side panel stopper portion 121 at the right end thereof, and is thus restricted from moving upward. When the cover 140 is closed in place, the cover lock 150 is biased toward the stop opening 1412 such that the lock stop 151 extends to the right into the side panel restraint 121.
The biasing action described above may be achieved by the biasing member 160. As shown in fig. 2A and 2B, the biasing member 160 is a spring that is located between the cover plate lock accommodating part 141 and the cover plate lock 150, specifically, between the left end of the cover plate lock accommodating part 141 and the right end of the cover plate lock 150 and biases the cover plate lock 150 to the right. In this case, a blind hole is preferably provided at the left end of the cover locking member 150 to accommodate a portion of the spring so that spring displacement will be avoided.
It should be understood that the biasing member 160 may be other resilient members such as a U-shaped spring. In another embodiment, not shown, the locking member stopper 151 may be at least partially made of an elastic material so that the locking member stopper 151 may be compressed in the left-right direction. When unlocking is required, the locking member operating part 152 is accessible through the operating part opening 1411 and the locking member stopper 151 is moved away from the side plate stopper 121 against the biasing force of the biasing member 160 or by compressing the elastic locking member stopper 151 to the left, thereby removing the cover plate 140.
Further, the right end of the locking member stopper 151 includes a locking member guide 1511 which is a slope gradually receding from the top to the other end. The guide portion 1511 facilitates the cover lock 150 to be put in from above when the cover lock 150 is put in the cover lock accommodating portion 141.
Another perspective view of the container 100 is shown in fig. 3, with the cover panel 140 in an open state. The locking structure between the side plates 120 and 130 is cut away. Fig. 3A and 3B show enlarged views of cut-away portions of the side panel lock 170 in the locked state and the unlocked state, respectively. An exploded perspective view of adjacent side panels 120 and 130 is shown in fig. 4. Fig. 4A and 4B show enlarged views of detail C and detail D in fig. 4, respectively.
As shown, the side plate 120 is provided at a lateral edge adjacent to the side plate 130 with a side plate lock receiving portion 131, and the side plate lock receiving portion 131 is for receiving the side plate lock 170. The side plate lock 170 includes a lock operation portion 172 and a lock stopper 171, and the lock operation portion 172 extends laterally, specifically leftward in fig. 3A and 3B, and rightward and upward in fig. 4B from the lock stopper 171. Specifically, as shown in fig. 3A, 3B and 4B, the lock member operating part 172 and the lock member stopper part 171 may be integrally formed. Preferably, as can also be seen in the figures, the tip of the lock operation part 172 is higher relative to the tip of the lock stopper part 171. Accordingly, the side plate lock accommodating part 131 has an operating part opening 1311 located above the top of the lock operating part 172 and a stopper opening 1312 located above the top of the lock stopper 171.
The lock operation part 172 is accessible through the operation part opening 1311 to operate the side plate lock 170. The locking member operating portion 172 is provided with a textured top surface to facilitate operation thereof. The locking member stopper 171 may protrude upward from the stopper opening 1312 to be engaged with the side plate limiting portion 132, so that the side plate limiting portion 132 limits the locking member stopper 171 and the side plate 120 to move laterally relative to the side plate 130. The side plate position-limiting portion 132 is located at an edge of the side plate 130. Specifically, as shown, a downwardly opening cavity is formed in the edge of the side plate 130 near the top, and the cavity forms a side plate stopper 132. When the locking member stopper 171 protrudes upward, it enters the side plate stopper 132, and is thus restricted from moving laterally. When the side plates 120 and 130 are in the standing state, the side plate lock 170 is biased upward so that the lock stopper 171 protrudes upward out of the stopper opening 1312 into the side plate stopper 132. In the illustrated embodiment, the side plate 130 is provided with a rib 134 extending toward the side plate 120, and a concave cavity, i.e., a side plate stopper 132, opened downward is formed inside the rib 134.
The biasing action described above may be achieved by a biasing member 180. As shown in fig. 3A and 3B, the biasing member 180 is a spring that is located between the side plate latch accommodating part 131 and the side plate latch 170, specifically, between the bottom end of the side plate latch accommodating part 131 and the bottom end of the side plate latch 170 and biases the side plate latch 170 upward. In this case, a blind hole is preferably provided at the bottom end of the side plate lock 170 to accommodate a portion of the spring so that spring displacement will be avoided.
It should be understood that the biasing member 180 may be other resilient members such as a U-shaped spring. In another embodiment, not shown, the lock stopper 171 may be at least partially made of an elastic material, such that the lock stopper 171 may be compressed in the vertical direction. When unlocking is required, the locking member operation part 172 is accessible through the operation part opening 1311 and the locking member stopper 171 is moved away from the side plate stopper 132 against the biasing force of the biasing member 180 or the elastic locking member stopper 171 is compressed leftward, so that the cover plate 120 is moved inward of the container 100 with respect to the cover plate 130 to be folded.
Further, the top end of the lock stopper 171 includes a lock guide 1711 which is a slope gradually decreasing in height from the inside to the outside. When the locking member stopper 171 enters the side plate limiting portion 132, the guiding portion 1711 facilitates guiding the entering of the locking member stopper 171, so as to prevent the locking member 170 from being stuck.
When the side plate lock 170 is mounted, the side plate lock accommodating portion 131 is fitted from above.
According to the above locking structure of the present invention, the cover plate locking member 150 and the side plate locking member 170 do not protrude from the outer surface of the side plate or the cover plate after being mounted in place. The surface integrality of curb plate and apron can be guaranteed under the condition that needs have the heat preservation function with curb plate and apron and set up the heat preservation intermediate layer. In addition, the locking structure does not need a handle or a lock catch protruding out of the surface of the cover plate or the side plate, and the compactness of the structure when the cover plate or the side plate is stacked is not influenced. And the locking structure is small in size, and the arrangement of the locking structure does not influence the strength of the side plates and the cover plate.
