Background

The hard open top container is compressed, sealed and locked by arranging a plurality of groups of side compression locks on the side wall. However, two problems exist with conventional hard open top containers:

1. the hard open top box applies acting force through the side pressing lock so that the top cover presses the box top beam through the sealing rubber strip to seal the gap between the top cover and the box top beam. The sealing rubber strip is a vulnerable part, and the sealing rubber strip slowly loses elasticity along with the time. For this purpose, the side-pressure locks are arranged to be adjustable (by adjusting the magnitude of the aforementioned force by means of bolts). With adjustable side compression locks, the nut may loosen from jolting during transportation.

2. At present, a plurality of side-pressing locks compress a pressing block on the upper part of a top cover through the head part of a locking rod so as to compress the top cover. Thus, if an external force impacts the head of the locking lever during transportation (e.g., a human being strikes the head of the locking lever), the head of the locking lever may rotate about the axis of the locking lever until the head of the locking lever disengages from the top cover. The top cap can not be locked by the side-pressing lockset at the moment, and the anti-theft effect is poor.

To this end, the present invention provides a hard open top container for at least partially solving the above problems.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

First embodiment

The preferred embodiment of the present invention provides a hard open top container. As shown in fig. 1 to 3, the hard open top container includes a body 110 and a top cover 120. The case 110 is configured in a substantially rectangular parallelepiped structure. The case 110 includes a bottom frame, side walls 112, and end walls. The top end of the case 110 is provided with a top opening 111. The top cover 120 removably covers the top opening 111.

The hard open top shipping container includes a hold down device 130. When the top cover 120 covers the top opening 111, the pressing device 130 is used for pressing the top cover 120 to the top opening 111.

Referring to fig. 1 to 3, the pressing device 130 includes a fixing base 139, an operating member 131, a movable member 133, a pressing rod 135, an adjusting member 137, and a limiting member 138. The holder 139 and the operating member 131 may be sheet metal parts.

The holder 139 includes a body 147 and a hinge ear 148. The body 147 may be a plate-like structure. The body 147 is fitted and connected (e.g., welded or riveted) to the outer side surface of the side wall 112 (the surface of the side wall 112 away from the inner space of the case 110). Two sides of the body 147 are bent and extended toward the external environment of the case 110 along the width direction of the case 110 to form hinge ears 148. Thus, hinge ears 148 project from body 147. The first end of the operating member 131 is hinged to the hinge ear 148. The second end of the operating member 131 is a free end. So that the worker can operate the second end of the operating member 131 to rotate the operating member 131 between the pressing position and the opening position.

The movable member 133 may be a columnar structure. An axial end of the movable member 133 may be pivotally connected to a first end of the operating member 131. So that the movable member 133 can rotate about its axis. The movable member 133 is provided with a through hole 134 at a substantially middle position in the axial direction thereof.

The lower end of the pressing rod 135 is rotatably inserted through the through hole 134. The top end of the side wall 112 is provided with a roof side beam 113. The roof side rail 113 is provided with a mounting hole 114 extending in the height direction of the case 110. The upper end of the hold down rod 135 extends upwardly through the mounting hole 114. Thus, the pressing rod 135 can rotate about its axis and can move up and down in its axial direction. It should be noted that the size of the mounting hole 114 is a predetermined size so that the pressing lever 135 does not interfere with the top side member 113 when the operating member 131 is rotated between the pressing position and the open position.

The upper end of the pressing rod 135 is provided with a pressing portion 136. The pressing portion 136 extends outward in the radial direction of the pressing rod 135. The pressing portion 136 is located above the top side member 113 in the height direction of the box body 110. The pressing portion 136 is used to press the top cover pressing plate 121.

The adjustment member 137 may be a nut. The adjustment member 137 is located on the side of the movable member 133 away from the pressing portion 136 in the axial direction of the pressing lever 135. The adjusting member 137 is screwed with a portion of the lower end of the pressing rod 135 protruding out of the through hole 134. In this way, the distance between the pressing portion 136 and the adjusting member 137 in the axial direction of the pressing rod 135 can be adjusted by adjusting the position of the adjusting member 137 on the pressing rod 135, and the magnitude of the force with which the pressing portion 136 presses the later top cover pressing plate 121 can be adjusted.

The operator can operate the second end of the operating member 131 to rotate the operating member 131 between the pressed position and the open position. When the operating member 131 is rotated from the open position to the pressing position, the operating member 131 applies a force to the pressing lever 135 to move it via the movable member 133 and the adjusting member 137. The operation member 131 thus moves the pressing lever 135. When the operation member 131 is located at the pressing position, the pressing portion 136 presses the top cover pressing plate 121 to press the top cover 120 to the top opening 111. If it is desired to open the top cover 120, the operating member 131 is moved from the pressing position to the open position. When the operating member 131 is positioned at the open position, only the weight of the pressing lever 135 and the pressing portion 136 acts on the top cover pressing plate 121, and at this time, the worker moves the pressing lever 135 upward to separate the pressing portion 136 from the top cover 120, and then rotates the pressing lever 135 by substantially 90 ° to move the pressing portion 136 to the top side member 113, so that the pressing portion 136 can be moved to the upper surface of the top side member 113 by the weight of the pressing lever 135 and the pressing portion 136 to allow the top side member 113 to support the pressing portion 136.

The stop member 138 is connected (e.g., riveted or welded) to the body 147 of the anchor block 139. Along the width of the case 110, the stop member 138 extends from the body 147 toward the environment of the case 110 to protrude beyond the sidewall 112. The adjustment member 137 is located below the movable member 133 and above the stopper member 138. Thus, when the operating member 131 is located at the pressing position, the stopper member 138 is located on the side of the adjustment member 137 away from the movable member 133 in the height direction of the case 110 (in which the axial direction of the pressing lever 135 extends in the height direction of the case 110), and the stopper member 138 contacts the adjustment member 137 (for example, the stopper member 138 contacts the lower surface of the adjustment member 137).

When the operating member 131 is located at the pressing position, the limiting member 138 can block the adjusting member 137 to prevent the adjusting member 137 from moving downward along the axial direction of the pressing rod 135, so as to prevent the adjusting member 137 from releasing the pressing action of the pressing part 136 on the top cover pressing plate 121. Further, the regulating member 137 can be prevented from coming off the pressing lever 135. For example, during the transportation of a hard open top container (when the operating member 131 is located at the pressing position), the adjusting member 137 may be rotated by the jolt during the transportation, and the limiting member 138 may prevent the adjusting member 137 from moving downward along the axial direction of the pressing rod 135, so as to prevent the adjusting member 137 from releasing the pressing action of the pressing portion 136 on the top cover pressing plate 121. Further, the regulating member 137 can be prevented from coming off the pressing lever 135.

Referring to fig. 2 and 3, when the adjusting member 137 is located at the open position, the pressing rod 135 is rotated, i.e., the distance between the pressing portion 136 and the adjusting member 137 in the axial direction of the pressing rod 135 is adjusted. Thereby, the magnitude of the pressing force of the pressing portion 136 against the top cover 120 is adjusted. For example, increasing the distance between the pressing portion 136 and the adjustment member 137 in the axial direction of the pressing rod 135 may reduce the force with which the pressing portion 136 presses the top cover 120. By decreasing the distance between the pressing portion 136 and the adjustment member 137 in the axial direction of the pressing rod 135, the force with which the pressing portion 136 presses the top cover 120 can be increased.

The operating member 131 is provided with a pin hole 132. The hold down device 130 also includes a locking pin 140. The hinge lug 148 of the fixing seat 139 is provided with a locking hole. When the operating member 131 is in the pressing position, the operating member 131 can be locked to the fixing seat 139 by passing the locking pin 140 through the pin hole 132 and the locking hole.

Preferably, the operating member 131 is provided at the pin hole 132 with a slip-off preventing groove extending outward in a radial direction of the pin hole 132. One end of the locking pin 140 is provided with an anti-slip protrusion, so that the anti-slip protrusion is opposite to the anti-slip groove, that is, the locking pin 140 can pass through the pin hole 132 and the locking hole, and at this time, the locking pin 140 is rotated, so that the anti-slip protrusion and the anti-slip groove are staggered, and the locking pin 140 can be prevented from falling out of the pin hole 132.

Preferably, the pressing device 130 further comprises a chain 142. The chain 142 is connected to the locking pin 140 and the holder 139. Thereby preventing the locking pin 140 from being lost.

The top cover 120 is provided with a top cover pressing plate 121. When the operating member 131 is located at the pressing position, the pressing portion 136 presses the top cover pressing plate 121, thereby pressing the top cover 120 to the top opening 111.

The end of the pressing portion 136 remote from the axis of the pressing rod 135 is provided with a hook 141. The hook 141 is formed by the pressing portion 136 extending toward the adjusting member 137 in the axial direction of the pressing rod 135. The top cover pressing plate 121 is provided with a locking hole 122. When the operating member 131 is in the pressing position, the free end of the hook 141 extends into the locking hole 122. Thus, the locking hole 122 can block the hook 141 from rotating around the axis of the pressing rod 135, thereby preventing the pressing portion 136 pressing the top cover pressing plate 121 from rotating to leave the top cover pressing plate 121. Therefore, the anti-theft effect is good.

The top cover 120 is further provided with a sealing rubber strip 123. The case 110 is provided at the top side beam with a top cover supporter 115. When the top cover 120 covers the top opening 111, the top cover 120 is pressed to the top cover supporter 115 by the sealing rubber strips 123. Thereby, the sealing rubber 123 may seal the gap between the top cover 120 and the case 110. Water leakage from the top opening 111 is avoided.

When the operating member 131 is in the pressing position, the operating member 131 is rotated to the open position. At this time, the worker may move the pressing rod 135 upward to disengage the hook 141 from the locking hole 122; then the hold-down lever 135 is rotated by 90 degrees to extend the hook 141 along the length direction of the case 110, and at this time, the worker can release the hold-down lever 135 to drop the hold-down lever 135 under the action of gravity, so that the hook 141 drops on the upper surface of the top side member 113, thereby facilitating the lifting and dropping of the top cover 120 without damaging the hook 141.

Second embodiment

In the second embodiment, as shown in fig. 4 to 7, the top cover pressing plate 221 of the top cover 220 is not provided with locking holes. At this time, the pressing portion 236 presses the top cover pressing plate 221 through the hook 241. When the pressing portion 236 presses the top cover pressing plate 221, the pressing portion 236 may be prevented from rotating to be separated from the top cover pressing plate 221 by the following rotation stopper 243.

In the second embodiment, the pressing device 230 further includes a rotation stopper 243. The rotation stop member 243 is connected to the side wall 212. The rotation stopper 243 is provided with a rotation stopper hole 244 and a rotation stopper 245. The rotation stop portion 245 is configured as a groove extending outward in the radial direction of the rotation stop hole 244 from the inner wall surface of the rotation stop hole 244. The rotation stop hole 244 is sleeved on the outer periphery of the pressing rod 235. Portions of the hold down bar 235 are provided with projections 246. The projection 246 is configured as a projection extending outward in the radial direction of the pressing rod 235 from a part of the outer periphery of the pressing rod 135. When the operating member 231 is in the pressing position, the projection 246 enters the rotation stopper 245. Thus, the rotation stopper 245 prevents the pressing rod 235 from rotating. Thus, when the operating member 231 is in the pressing position, the rotation stopper 243 may prevent the pressing lever 235 from rotating, thereby preventing the pressing portion 236 from rotating.

Preferably, the rotation stopper 243 is further provided with an escape portion 249. The escape portion 249 and the rotation stop portion 245 are spaced apart from each other in the circumferential direction around the axis of the rotation stop hole 244. The hold down bar 135 is provided with a projection 246. When the pressing portion 236 presses the top cover pressing plate 221, the protrusion 246 is located in the rotation stopping portion 245 (the rotation stopping portion 245 is located at the right side of the rotation stopping hole 244 shown in fig. 7), and the rotation stopping member 243 can prevent the pressing rod 235 from rotating, so that the pressing portion 236 is prevented from rotating to be away from the top cover pressing plate 221.

A line connecting a substantially central position of the stopper 245 and a center of the rotation stop hole 244 in the horizontal direction constitutes a first line, and a line connecting a substantially central position of the escape portion 249 and a center of the rotation stop hole 244 constitutes a second line. The angle alpha between the first and second lines is 90 deg..

When the operating member 231 is in the pressing position, the operating member 231 is rotated to the open position. At this time, the worker can move the pressing rod 235 upwards to separate the hook 241 from the top cover pressing plate 221; then, the pressing rod 235 is rotated by 90 degrees so that the hook 241 extends along the longitudinal direction of the case 210, and the protrusion 246 faces the escape part 249. The worker can release the pressing lever 235 so that the pressing lever 235 falls under the gravity of the pressing lever 235 and the pressing portion 236, and thus the hook 241 falls on the upper surface of the top side member 213. During the dropping of the pressing rod 235, the projection 246 moves through the escape 249. Thus, the top cover 220 can be conveniently lifted and dropped, the hook head 241 cannot be damaged, and the hook head 241 cannot rotate.

When the hook head 241 is located on the upper surface of the top side member 213, the worker may move the pressing rod 235 upward to move the hook head 241 to above the upper surface of the top cover pressing plate 221 in the height direction of the case 210. In this process, the hook 241 is separated from the top side member 213, and the protruding portion 246 moves through the escape portion 249. Then the pressing bar 235 is rotated approximately 90 degrees so that the hook 241 extends in the width direction of the case 210; then, the operating member 231 is rotated from the open position to the pressing position, so that the hook 241 presses the top cover pressing plate 221.

It should be noted that the top opening 211, the mounting hole 214, the top cover support 215, the sealing rubber strip 223, the pin hole 232, the movable member 233, the through hole 234, the adjustment member 237, the stopper member 238, the fixing base 239, the locking pin 240, the chain 242, the body 247, and the hinge lug 248 of the second embodiment are substantially the same as the top opening 111, the mounting hole 114, the top cover support 115, the sealing rubber strip 123, the pin hole 132, the movable member 133, the through hole 134, the adjustment member 137, the stopper member 138, the fixing base 139, the locking pin 140, the chain 142, the body 147, and the hinge lug 148 of the first embodiment.
