Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in Figure 1 and Figure 3, the lockset of the present invention is applied to a pallet box with foldable end and side walls. This pallet box 1 comprises two end walls 100 , two side walls 200 and a chassis 300 . The two end walls 100 and the two side walls 200 are respectively hinged on the four sides of the chassis 300 . Two end walls 100 can be stacked on the chassis 300 , and then two side walls 200 can be stacked on the end walls 100 .

As shown in FIG. 2 , the side wall 200 includes a side wall body 210 and a side wall column 220 located on a side of the side wall body 210 . The end wall 100 includes an end wall body 110 , an end wall top beam 120 located at an upper end of the end wall body 110 , and an end wall column 130 located at a side of the end wall body 110 . The end wall column 130 includes a flat plate portion 131 and a U-shaped portion 132 . The flat plate portion 131 extends laterally from one side of the U-shaped portion 132 to a direction away from the side wall column 220 . Referring to FIG. 4F , the flat plate connection portion 132 a of the U-shaped portion 132 is connected to the flat plate portion 131 , the end wall fitting portion 132 b is closely attached to the end wall, and the side wall column fitting portion is closely attached to the side wall column 220 .

After the pallet box 1 is assembled, the end wall 100 and the side wall 200 are connected together by two locks 400 respectively arranged at the left and right ends of the end wall 100 .

Referring to Fig. 2 and Fig. 4A-Fig. 4F, the lock 400 of this embodiment includes a lock base 410 fixed on the lower side of the end wall top beam 120, an elastic member 420, a lock plate 430 connected with the lock base 410 through a rotating shaft 414, and a connecting The locking catch 440 on the side wall column 220 is used to cooperate with the locking plate 430 .

As shown in Fig. 2 and Fig. 4C, the lock base 410 includes a slender plate-shaped bottom plate 411, a vertical plate 412 located at one end of the bottom plate 411 along the lengthwise direction, and a positioning position positioned at the other end of the bottom plate 411 along the lengthwise direction. pin 413. The upper surface of the bottom plate 411 is closely attached to the lower surface of the end wall top beam 120 . One end of the vertical plate 412 is connected to the lower surface of the bottom plate 411 , and the other end is away from the bottom plate 411 and extends vertically downward. The other end of the vertical plate 412 away from the bottom plate 411 is provided with a hole for installing the rotating shaft 414 . One end of the positioning pin 413 is connected to the lower surface of the bottom plate 411 , and the other end is away from the bottom plate 411 and extends vertically downwards for sheathing the elastic member 420 . Of course, those skilled in the art can understand that the lock seat 410 can also be directly fixed on the top beam of the end wall without including a bottom plate.

As shown in FIG. 2 and FIG. 4A , the locking plate 430 includes an elongated plate-shaped main body portion 434 , a horizontal portion 431 , a retaining portion 433 and a locking portion 432 for cooperating with the locking block 440 .

The horizontal portion 431 is connected to the bottom of the main body 434 and extends horizontally from the outer side of the locking plate 430 toward the end wall. The horizontal portion 431 not only provides the working surface of the elastic member 420 to bear the pressure of the elastic member 420, but also serves as a handle, which is convenient for the operator to operate the lock.

One end of the main body part 434 along the length direction is provided with a hole for installing the rotating shaft 414, and the other end along the length direction is provided with a retaining part 433 and a locking part 432, wherein the retaining part 433 is close to the end wall as a whole relative to the main body part 434 The locking portion 432 protrudes away from the end wall, so that the retaining portion 433 forms a U-shaped depression relative to the main body portion 434 and the locking portion 432 . The flat portion 131 of the end wall column 130 is located in the recessed space formed by the fixing portion 433 , so that the outer surface of the flat portion 131 and the outer surface of the main body portion 434 of the locking plate 430 are in the same plane. In this way, the outer surface of the flat plate portion 131 does not protrude from the outer surface of the end wall top beam 120. On the one hand, the thickness of the end wall 100 can be reduced, and on the other hand, mutual extrusion of the end wall 100 and the side wall 200 can be avoided pressure damage. If the retaining portion 433 is not set in a concave form, the flat plate portion 131 of the end wall column 130 needs to protrude from the outer surface of the main body portion 434 of the locking plate 430, and then protrude from the outer surface of the end wall top beam 120, and the end wall 100 When being folded together with the side wall 200 , the flat plate portion 131 of the protruding end wall column 130 and the side wall 200 may be damaged due to mutual compression. In addition, because the thickness of this lock is thinner than other common types of locks, the thickness of the end wall of the pallet box can be reduced, so the empty box folding height of the pallet box is lower than other common types of pallet boxes, and the empty box is transported More packing capacity can be obtained at the same time, effectively reducing the transportation cost of empty containers, and a larger volume ratio will be obtained after the pallet boxes are assembled.

As shown in FIG. 4E and FIG. 4F , the upper end of the end wall column 130 is provided with a retaining hole 133 at the position corresponding to the lock plate 430 , more specifically, at the connection position between the flat plate portion 131 and the U-shaped portion 132 . The height of the retaining hole 133 is slightly larger than the vertical width of the locking portion 432 and the retaining portion 433 at the end of the locking plate 430 . The locking portion 432 of the locking plate 430 passes through the fixing hole 133 and covers the U-shaped portion 132 of the end wall column 130 . Part of the retaining portion 433 is covered by the flat plate portion 131 , and the retaining hole 133 limits the pivoting range of the locking plate 430 in the first pivoting direction and the second pivoting direction. More specifically, the upper edge and the lower edge of the retaining hole 133 respectively define the highest point H of the upper edge and the lowest point L of the lower edge of the retaining portion 433 of the locking plate 430 within the range of motion.

In addition, as shown in FIG. 4F , the end wall column 130 is provided with a limiting hole 134 on the end wall adhering portion 132 b of the U-shaped portion 132 , so as to cooperate with the locking stopper 440 , which will be described in detail below.

The elastic member 420 is pressed between the bottom plate 411 of the lock seat 410 and the lock plate 430 and sleeved on the positioning pin 413 of the lock seat 410 , as shown in FIG. 4E , one end of the elastic member 420 is close to the bottom plate 411 of the lock seat 410 The other end is close to the horizontal part 431 of the lower end of the lock plate 430, and has a downward elastic force on the horizontal part 431, so that when the lock is locked, the retaining part 433 of the lock plate 430 The lower edge of the lower edge is at the lowest point L, so that the locked state of the lock is more stable. In addition, the free length S of the elastic member 420 is greater than the distance between the horizontal portion 431 and the bottom plate 411. Therefore, the elastic member will be there after installation. A certain initial pressure keeps the locking plate 430 in place.

The elastic member is preferably a cylindrical helical compression spring, or other elastic members such as rubber or leaf spring. Depending on the structural shape of the elastic member, the positioning pin can also be eliminated. The rotating shaft 414 is preferably perpendicular to the end wall body 110, so that the plane where the rotation path of the lock plate 430 is parallel to the plane where the end wall body 110 is located, so that no matter in the open or locked state, the outermost surface of the lock plate 430 does not protrude On the outer surface of the end wall top beam 120 , the end wall top beam 120 plays a role of protecting the lock 400 , and can avoid damages such as extrusion of the side wall 200 to the lock 400 after the end wall 100 is folded. The size of the rotating shaft 414 is designed so that the locking plate 430 can rotate freely.

As can be seen from FIGS. 5 and 6 , the lock block 440 is connected to the side wall column 220 and includes a fixing portion 441 and a stop portion 442 . The fixing portion 441 is fixedly connected with the side wall column 220 . The stop portion 442 is plate-shaped and extends parallel to the side wall body 210 toward the inner side of the end wall 100 of the pallet box. The fixing portion 441 and the stop portion 442 are integrally formed, and the planes where the two are located are perpendicular to each other.

As shown in detail in FIG. 6 , the stopper 442 includes a stopper body 442 a , a first limiter 442 b , a guide slope 442 c and a second limiter 442 d . The first limiting portion 442b is a vertical surface close to the fixing portion 441 and vertically extending upward from the fixing portion top surface 441a of the fixing portion 441 . The guide slope 442c slopes downward from the highest position of the first limiting portion 442b to a side away from the fixing portion 441 . The second limiting portion 442d protrudes from the stopper body 442a in a direction away from the fixing portion 441 to form a hook-shaped protrusion, and its upper surface is in smooth contact with the guiding slope 442c and is on the same plane. The size of the second limiting portion 442d is just enough to be inserted into the limiting hole 134 of the end wall fitting portion 132b of the U-shaped portion 132 of the end wall column 130 , as best shown in FIGS. 13 , 15 and 16 .

The locking and unlocking process of the pallet box 1 will be described below.

Locking process of pallet box 1:

It can be seen from Figs. 7-9 that the operator first lifts the side wall 200, and when the side wall 200 reaches an upright state, the side wall 200 is fixed on the chassis. Next, the end wall 100 is lifted, and as the end face of the end wall 100 is lifted along the inner surface of the side wall, the locking portion 432 of the lock plate 430 arranged on the end wall 100 first contacts the lock block 440 arranged on the side wall The guide slope 442c of the stopper 442 (FIG. 8). At this time, if the end wall 100 continues to be pulled hard, the locking part 432 will abut against the guide inclined surface 442c and move upward, and the guide inclined surface 442c provides an upward supporting force, which is greater than that provided between the end wall 100 and the locking part 432. The downward elastic force provided by the spring makes the locking portion 432 continue to slide upward along the guiding slope 442c. Here, in order to make the lock part 432 slide upwards smoothly along the guide slope 442c, the bottom of the lock part 432 is set as a slope matching the guide slope 442c (as shown in Figures 7 and 8), and this slope is consistent with the guide slope 442c. The incline 442c cooperates so that the lock can smoothly complete the automatic locking process. When the locking portion 432 passes over the top end of the guide inclined surface 442c, the locking portion 432 falls along the first limiting portion 442b, and the inner surface of the locking portion 432 close to the end wall is in close contact with the surface of the first limiting portion 442b , and under the action of the elastic member 420, the lower end of the locking portion 432 leans against the top surface 441a of the fixing portion 441 ( FIG. 9 ). Meanwhile, as shown in FIG. 13 , the second limiting portion 442d is inserted into the limiting hole 134 provided on the end wall column 130 . As shown in FIG. 15 , the side elevation of the stopper body 442 a close to the side wall 200 is in close contact with the inner elevation of the U-shaped portion 132 c of the side wall column fitting portion 132 c of the U-shaped portion 132 of the end wall column 130 , so Through the cooperation of the lock seat 410, the lock plate 430, the lock block 440 and the end wall column 130, the end wall 100 is fixed in front, rear, left, right, up and down directions relative to the side wall 200. Since the side wall 200 is relatively fixed to the chassis, the end wall 100 is relatively fixed to the chassis through the side wall 200 . The entire locking process of the lock does not require the operator to operate the lock, but the operator only needs to pull the end wall to the outside of the box at the same time to lock the lock. Moreover, after the lock is locked, the pressure of the elastic member 420 keeps the lock plate at the locked position all the time, so that the lock always maintains the locked state. In addition, since the first limiting portion 442b is located inside the locking plate, the end wall 100 can be prevented from falling into the box by the first limiting portion 442b, so that the end wall 100 remains stable in the locked state.

10 and 11 show how the lock 400 is unlocked. During the unlocking process, the operator lifts or kneads the lock plate 430 by hand to make it rotate around the rotating shaft 414 to reach or approach the highest position H, which is the uppermost end of the retaining hole 133, and keep pushing it toward the inside of the box. end wall 100 . At this time, the locking portion 432 of the locking plate 430 passes over the first limiting portion 442 b of the stop portion 442 of the locking block 440 , so that the locking plate 430 is separated from the locking block 440 . As a result, the second limiting portion 442d of the lock is also disengaged from the limiting hole 134 provided on the end wall column 130, and the lock 400 is in an unlocked state. The unlocking action can be operated with one hand, so that the operator can operate two locks at the same time with both hands, and the two locks are unlocked at the same time, which greatly improves the operating efficiency.

The matching relationship and dimensional design of various components related to the lock 400 will be described in more detail below.

Fig. 12 is a front view of part A of Fig. 1 . 13 and 14 are cross-sectional views taken along line I-I in FIG. 12 , FIG. 13 shows the lock 400 in a locked state, and FIG. 14 shows the lock 400 in an unlocked state. Fig. 15 is a cross-sectional view taken along line H-H in Fig. 12, and Fig. 16 is a partial perspective view of part A viewed from the inside of the box, at this time, the lock 400 is in a locked state.

In the unlocked state, as shown in FIG. 14 , the second limiting portion 442d is not accommodated in the limiting hole 134 . In the locked state, as shown in Figures 13, 15 and 16, the second limiting portion 442d matches the size of the limiting hole 134, the second limiting portion 442d is accommodated in the limiting hole 134, and the locking plate 430 The locking portion 432 is placed on the fixing portion 441 of the locking block 440 . As an example, the specific dimensions are designed as follows:

When the elastic member 420 exerts an elastic force downward so that the lower edge of the retaining portion 433 of the lock plate 430 is at the lowest point L ( FIG. 17 ), the distance from the upper surface of the retaining portion 433 to the upper opening end of the retaining hole 133 is The vertical distance A (Fig. 17) is greater than or equal to the vertical distance A1 (Fig. The locking part 432 can smoothly pass over the highest position of the first limiting part 442b of the stopper part 442 and abut against the top surface 441a of the fixing part 441 of the fixing part 441, and the locking part 432 can also abut against the first limiting part at the same time. part 442b.

The distance B ( FIG. 17 ) from the lower opening end of the fixing hole 133 to the lower surface of the limiting hole 134 is the same as the distance B1 ( FIG. 20 ) from the top surface 441 a of the fixing part of the fixing part 441 to the bottom end of the second limiting part 442 d. Matching, so that when the lock 400 is in the locked state, the second limiting portion 442d is just inserted into the limiting hole 134, and also ensures that the locking portion 432 of the locking plate 430 can stably abut against the top of the fixing portion of the fixing portion 441 on the surface 441a.

The height C ( FIG. 17 ) of the limiting hole 134 matches the height C1 ( FIG. 20 ) of the second limiting portion 442d, so that when the pallet box is assembled, the end wall 100 is fixedly connected to the chassis 300 .

The thickness D ( FIGS. 17 and 18 ) of the U-shaped portion 132 of the end wall column 130 near the side wall column 220 is smaller than the width D1 ( FIG. 21 ) of the space formed between the stopper 442 and the side wall column 220 . ). In this way, when the lock 400 is locked, the stopper portion 442 and the side wall column 220 just clamp the wall portion of the U-shaped portion 132 of the end wall column 130 near the side wall column 220 .

The width dimension E (FIGS. 17 and 18) of the limiting hole 134 matches the length E1 (FIG. 21) of the second limiting portion 442d of the lock block 440, so that the second limiting portion 442d can be smoothly accommodated in the limiting position. bit hole 134.

The distance F ( FIG. 18 ) from the outer surface of the end wall bonding portion 132b of the U-shaped portion 132 of the end wall column 130 to the inner panel of the box body and the length F1 ( Figure 20) are basically equal. If F1 is obviously greater than F, the second stopper 442d will protrude into the box and form a protrusion in the box. This protrusion will affect the stability of the end wall stacked on the rear end wall of the chassis, and the height of the folded pallet box. It will cause damage to the bottom plate of the chassis 300, and after the pallet box is assembled, the contents may be damaged. If F1 is obviously smaller than F, then the second limiting portion 442d cannot provide a reliable limiting effect.
