Description

Pallet box

Technical Field

The invention relates to the technical field of containers, in particular to a pallet box.

Background

As shown in fig. 1, the tray box is generally composed of a chassis, two side walls disposed on opposite sides of the chassis, and two end walls disposed on the other opposite sides of the chassis, the two end walls being disposed between the two side walls, and tray box locks disposed on the two end walls to lock the assembled end walls and side walls. Tray box locks are commonly in the form of both straight locks and hook locks.

The locking rod of the straight lock is a straight rod, when the tray box lockset is locked, the locking rod is inserted into the round locking hole of the side wall, the movement of the end wall along the up-down direction and the inside-outside direction of the tray box can be limited, the horizontal relative movement between the end wall and the side wall is realized by means of the hook plate arranged on the side wall, but the tray box provided with the hook plate with a general structure is hooked with the end wall and the side wall, and even if the straight lock is opened, the end wall and the side wall cannot be detached towards the outside direction of the box. Therefore, when the end wall or the side wall is required to be detachable in the outer direction of the box, or the half folding door arranged at the upper half part of the end wall or the side wall is required to be opened in the outer direction of the box by rotating downwards, a hook lock is generally adopted, the hook lock is formed by adding a hook head at the head part of a lock rod of a direct lock, and when a tray box lockset is locked, the hook head of the hook lock is inserted into a long lock hole (generally the long lock hole is in the vertical direction) of the side wall, and then the lock rod is rotated for a certain angle, so that the hook head hooks the side wall, and the locking of the end wall and the side wall is realized.

However, since the lock rod is engaged with the long lock hole, there is a possibility of relative movement of the end wall or the side wall in the up-down direction, which is divided into two cases: 1. the tray box lockset faces to the box after being locked, and when the lock rod is inserted into the long lock hole, the lock rod is required to be inserted by the upper end of the long lock hole, namely the hook head is downwards inserted into the long lock hole. After the tray box lockset is locked, a fit gap is formed between the lower surface of the lock rod and the lower end of the long lock hole, and the side wall can move upwards relative to the end wall. If the tray box lock is limited by the structure of the end wall or the side wall, the hook head can only face the box when the tray box lock is locked, the user also requires that the side wall can be detached, and only the end wall can be connected with the chassis, and then the tray box lock can not limit the upward movement of the side wall. 2. The tray box lockset faces the outside of the box after being locked, and when the lock rod is inserted into the long lock hole, the lock rod is required to be inserted by the lower end of the long lock hole, namely the hook head is upwards inserted into the long lock hole. After the tray box lockset is locked, a fit gap is formed between the upper surface of the lock rod and the upper end of the long lock hole, and the end wall can move upwards relative to the side wall. If the tray box lock is limited by the structure of the end wall or the side wall, the hook heads can only face to the outside of the box when the tray box lock is locked, the user also requires that the end wall can be detached, and only the side wall can be connected with the chassis, so that the tray box lock can not limit the upward movement of the end wall. The upward movement of the end walls or side walls can cause gaps between the end wall underbeam or side wall underbeam and the chassis, causing the cargo to scatter, and possibly clamping or damaging the inner liner bag for containing the cargo. The end wall and the side wall are relatively moved to make the locking of the tray box lock unstable, and the tray box has potential safety hazards during transportation.

It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", and the like are used herein for illustrative purposes only and are not limiting.

Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meaning, such as a particular order or the like. Also, for example, the term "first component" does not itself connote the presence of "second component" and the term "second component" does not itself connote the presence of "first component".

First embodiment

As shown in fig. 1, a pallet box 10 according to a preferred embodiment of the present invention is composed of a chassis 1, two side walls 2 oppositely provided on the chassis 1, and two end walls 3 oppositely provided on the chassis 1. The side walls 2 and the end walls 3 are alternately arranged.

As shown in fig. 13, the end wall 3 includes end wall side vertical beams 31, and the end wall side vertical beams 31 are located on both sides of the end wall 3 and have an inner space. When the end wall 3 is assembled in a vertical state, the fixing hole arranged at the lower part of the end wall edge vertical beam 31 is matched with the fixing pin 6 (shown in figure 1) arranged on the chassis 1, so that the end wall 3 is connected with the chassis 1, and the end wall 3 is prevented from moving upwards relative to the chassis 1. The side wall 2 is detachable and not connected to the chassis 1. The end wall 3 is connected to the side wall 2 by a pallet bin lock 4.

Turning now to fig. 2, the side wall 2 includes side wall edge risers 21. The side wall of the side vertical beam 21 is provided with a long lock hole 211, and the outer side wall of the side wall vertical beam 21 is provided with a round lock hole 212.

As shown in fig. 3 and 4, the tray box lock 4 in the present embodiment includes a lock base 43, a lock lever 41, a lock lever hook 411, and a lock lever handle 42.

Specifically, the lock base 43 includes a back plate and two side plates connected to both sides of the back plate, and the back plate and the side plates enclose a structure having a U-shaped cross section, so that the lock base 43 has an accommodation space opened toward one side thereof (the outside of the tray box 10).

The two side plates are respectively provided with a lock lever hole 431 for the lock lever 41 to extend therethrough. The locking lever 41 is connected to the locking seat 43 through the locking lever hole 431, the middle portion of the locking lever 41 is located in the accommodating space, and both ends of the locking lever 41 protrude out of the accommodating space.

Further, both ends of the lock lever 41 are defined herein as a lock lever extending end 412 near the side wall 2 and an outer end opposite to the lock lever extending end 412, the outer end being distant from the side wall 2, respectively. The lock lever 41 is movable in the horizontal direction with respect to the lock base 43, in other words, the lock lever 41 is movable in the axial direction thereof.

With continued reference to fig. 3, the locking lever handle 42 needs to be connected to at least a portion of the locking lever 41 that is located in the receiving space. Fig. 3 exemplarily configures the locking lever handle 42 in a U shape, one of the vertical bars of the U-shaped locking lever handle 42 is connected to a portion of the locking lever 41 located in the receiving space, and the other vertical bar is connected to an outer end of the locking lever 41 located outside the receiving space. To facilitate the operator's handling of the locking lever handle 42, a portion of the locking lever handle 42 may be bent away from the lock base 43. For example, as shown in fig. 3, the lower halves of the two vertical rods of the U-shaped locking lever handle are bent together with the horizontal connecting rod in a direction away from the locking seat 43.

The lock lever hook 411 is provided on the lock lever 41 and protrudes outward in the radial direction of the lock lever 41, and the lock lever hook 411 is close to the lock lever extending end 412 and spaced apart from the lock lever extending end 412. In the illustrated embodiment, the locking bar extension 412 is coaxial with the locking bar 41, but in an embodiment not shown, the locking bar extension 412 may not be coaxial with the locking bar 41, for example, the axis of the locking bar extension 412 may be disposed parallel to the axis of the locking bar 41.

The lock lever 41, the lock lever hook 411, and the lock lever handle 42 are integrally pivotable with respect to the lock base 43 about the axis of the lock lever 41 to switch between the locked state shown in fig. 3 and the unlocked state shown in fig. 13.

The locking bar hook 411 is used to hook the side wall 2 adjacent to the end wall 3 where the pallet bin lock 4 is located in the locked state. Referring to fig. 3 and 5, when the lock lever handle 42 is in a state of extending vertically downward from the lock lever 41, the lock lever hook 411 protrudes from one end of the lock lever in a direction opposite to the opening direction of the accommodating space, and is inclined upward with respect to the horizontal plane to form an angle A1 (fig. 5), at which time the tray box lock 4 is in a locked state.

When unlocking is required, the lock lever handle 42 needs to be lifted up to drive the lock lever hook 411 to rotate anticlockwise (as viewed from the perspective of fig. 5), and when the lock lever hook 411 rotates to the unlocking state, the lock lever handle 42 can be pulled horizontally (along the axial direction of the lock lever 41), so that the lock lever hook 411 withdraws from the long lock hole 211 from the side wall 2, and the connection between the lock lever hook 411 and the connected side wall 2 is released. In the illustrated embodiment, when the lock lever hook 411 is in the unlocked state, the lock lever hook 411 is vertically downward, and the state of the lock lever hook 411 in the unlocked position may be adjusted according to the actual situation.

In the unlocked state, the locking bar hook 411 can extend through the long locking hole 211. In other words, in the unlocked state, the radial cross section formed by the lock lever hook 411 and the lock lever 41 can be substantially aligned with the long lock hole 211, so that the lock lever 41, the lock lever hook 411, and the lock lever handle 42 can be integrally moved along the axis of the lock lever 41 without being blocked by the long lock hole 211. Further, the lock lever 41, the lock lever hook 411, and the lock lever handle 42 are integrally movable along the axis of the lock lever 41 with respect to the lock base 43 between the retracted position and the extended position.

Herein, the retracted position refers to a position where the lock lever 41 is withdrawn from the side wall 2 as shown in fig. 13, where the lock lever 41 does not extend beyond the end wall 3, thereby avoiding interference with the side wall 2. In the extended position, the locking bar extension 412 extends into the round locking hole 212. When the pallet box lock 4 is locked, the lock rod hook 411 passes through the long lock hole 211 on the side vertical beam 21 of the side wall, at this time, because a vertical gap exists between the long lock hole 211 and the lock rod 41, the side wall 2 and the end wall 3 can relatively move in the vertical direction, but after the lock rod extending end 412 outside the lock rod hook 411 passes through the round lock hole 212 on the side vertical beam of the side wall 2, the lock rod 41 can be positioned relative to the side wall 2, so that the relative movement along the radial direction of the lock rod cannot occur between the side wall 2 and the end wall 3.

Preferably, as shown in fig. 3, a pallet may be provided in the accommodation space, for example, the pallet may be provided on the back plate. When the lock lever 41 is attached to the lock base 43, the blade is supported below the lock lever 41, and an upwardly extending edge guard 432 is provided at an end of the blade outside the lock lever 41. As mentioned above, the lock lever handle 42 is connected to at least a portion of the lock lever 41 located in the accommodating space, so that the lock lever handle 42 is held by the edge guard 432 of the pallet to maintain the current state after being lifted and moved to the retracted position, so that when the end wall 3 is folded to be horizontal, the lock lever handle 42 is angled downward at an angle A1 from the vertical surface, and the lock lever handle 42 is rotated downward under its own weight and is abutted against the end wall 3.

Also preferably, since the lock lever handle 42 is connected to at least a portion of the lock lever 41 located in the accommodation space, a stopper 433 may be provided in the accommodation space in order to hold the lock lever handle in its own position when the tray box lock 4 is in the locked position. The stopper 433 is located below the lock lever 41 for blocking movement of the lock lever handle toward the retracted position in the locked state.

In the illustrated embodiment, the stop 433 is located between the side plates on both sides of the lock housing 43 and is configured as a vertical plate, on the side of which facing the side plates a stop projection is provided. Still taking a U-shaped lock lever handle as an example, as shown in fig. 3, one vertical bar of the U-shaped lock lever handle is restricted in a space between the vertical plate and the side plate, and the vertical bar cannot rotate due to friction of the stopper protrusion, so that the lock lever handle is maintained in the locked position, in other words, the stopper protrusion can prevent the lock lever handle from rotating in a direction away from the receiving space.

In addition, the lock base further includes a limiting portion 434, and the limiting portion 434 is connected to the back plate and disposed between the two side plates for blocking movement of the lock lever handle 42 toward the extended position in the unlocked state. When the lock is in the unlocked state, the lock bar hook 411 and the lock bar extension end 412 are retracted into the end wall side vertical beam 31, after the end wall 3 is folded to be horizontal, the lock bar handle 42 rotates downwards under the action of dead weight and is located at the side edge of the limiting part 434, and the lock bar handle 42 cannot move towards the overhanging position due to the blocking of the limiting part 434, so that the lock bar extension end 412 cannot extend out of the end wall side vertical beam 31, and interference with the side wall 2 due to the fact that the lock bar extension end 412 extends out of the end wall side vertical beam 31 can be avoided.

Therefore, the tray box lockset 4 does not need to fix the lock rod handle in the unlocking state, so that the operation of the tray box lockset 4 is simplified and misoperation is avoided.

In order to allow the lock lever handle 42 to smoothly advance to the side of the limit portion 434 when the end wall 3 is folded, the limit portion 434 is optionally provided with a guide slope 435 at a corner portion remote from the back plate and remote from the extended end 412 of the lock lever.

Turning now to fig. 5, when the lock lever hook 411 is configured to face into the box in the locked state, the angle between the lock lever hook 411 and the horizontal plane is A1, as shown in fig. 6, the lock lever 41 penetrates along the upper portion of the long lock hole 211 on the side vertical beam of the side wall 2, that is, the lock lever hook 411 penetrates downward into the long lock hole 211, and the fit gap D1 between the long lock hole 211 and the lock lever 41 is below the lock lever 41. The side wall 2 cannot be lifted up relative to the end wall 3 by the engagement of the extended end 412 of the lock bar on the outside of the lock bar hook 411 with the circular locking hole 212 on the side vertical beam.

In addition, as shown in fig. 4, the lower corners of the side plates may be provided with inclined surfaces 436 to prevent injury to the user when the locking lever handle 42 is operated.

In addition, the lower corners of the side plates are provided with inclined surfaces 2436.

As shown in fig. 8, the locking bar hook 2411 in the locked state faces the outside of the case (the included angle between the locking bar hook 2411 and the horizontal plane is A2), the locking bar 241 penetrates along the lower portion of the long locking hole 211 on the side vertical beam 21 of the side wall 2, and the fit gap D2 between the long locking hole 211 and the locking bar 241 is above the locking bar 241. The end wall 3 cannot be lifted upwards relative to the side wall 2 by matching the extended end 2412 of the lock rod at the outer side of the lock rod hook 2411 with the round lock hole 212 on the side vertical beam 21 of the side wall 2, and the locking device is suitable for the condition that the side wall 2 is connected with the chassis and the end wall 3 is not connected with the chassis.
