At the same time, this box type unit can be assembled in batches. Summary of the Invention

[0003] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is as follows: a drawer-type packaging box that can be opened in multiple directions at the same time, comprising at least an outer shell and an inner box, the outer shell comprising at least a bottom plate, the inner box being divided into an upper part and a lower part, the lower part of the inner box being composed of a plurality of bidirectional drawer-type box-type units arranged in parallel, each bidirectional drawer-type box-type unit comprising two drawer-type box bodies with opening directions opposite to each other and a push-pull mechanism located at the bottom of the two drawer-type box bodies, the push-pull mechanism comprising two chains respectively fixed to the bottom of the drawer-type box bodies and a double-layer gear located in the middle of the bottom of the two drawer-type box bodies, the double-layer gear being The structure is an integrated structure consisting of an upper gear with a smaller diameter and a lower gear with a larger diameter, wherein the lower gear is engaged with two chains at the same time, and the two chains are distributed on both sides of the lower gear; a transmission mechanism is provided in the middle between each two adjacent two-way drawer-type box-shaped units, and the transmission mechanism includes a spring fixed to the bottom plate of the shell and a transmission gear fixed to the upper end of the spring. The diameter of the transmission gear matches the spacing between the two upper gears on both sides. When the spring is compressed, the transmission gear is engaged with the two upper gears on both sides at the same time. When the spring is not compressed, the transmission gear is separated from the upper gears.

[0004] An isolation bar is provided on the upper part of the inner box. A through hole is provided on the isolation bar above the position of each transmission gear. The diameter of the through hole matches the diameter of the transmission gear. The end of the isolation bar on one side of the through hole is provided with a slider and a slide rail, and the end of the isolation bar on the other side is a baffle. The length of the slider and the slide rail is greater than the diameter of the through hole.

[0005] Moreover, a support column is provided between every two adjacent two-way drawer-type box units, and the height of the support column is equal to the distance between the bottom surface of the upper part of the inner box and the bottom plate of the outer shell.

[0006] Moreover, each drawer-type box body is provided with a protruding pull ring or pull rope on the surface where the opening direction is located.

[0007] Moreover, a magnetic sheet is provided on one side of the upper portion of the inner box close to the front plate of the outer shell, and a magnet matching the magnetic sheet is provided on the front plate of the outer shell.

[0008] Moreover, a slide groove is provided on the bottom plate below each chain position, a gear mounting position is provided on the bottom plate below each double-layer gear position, and a spring mounting position is provided on the bottom plate below each spring position.

[0009] Moreover, the shell is composed of a front plate, a top plate, a rear plate and a bottom plate which are sequentially connected as one body, and the size of the bottom plate is equal to or larger than that of the top plate.

[0010] Compared with the existing technology, the beneficial effects of this technical solution are:

[0011] 1. The push-pull mechanism at the bottom of the two drawer-type boxes includes two chains fixed to the bottom of the drawer-type boxes and a double-layer gear located in the middle of the bottom of the two drawer-type boxes. The lower gear is engaged with the two chains at the same time and the two chains are distributed on both sides of the lower gear. When a pull ring or a pull rope is used to open any drawer-type box, the chain will drive the lower gear to rotate, and the rotation of the lower gear will drive the chain on the other side. Since the chain is fixed to the bottom of the drawer-type box, the opposite drawer-type box will be opened at the same time.

[0012] 2. A transmission mechanism is provided in the middle between every two adjacent two-way drawer-type box-type units. When the spring is compressed, the transmission gear engages with the two upper gears on both sides at the same time. Since the upper gear and the lower gear rotate synchronously, when one upper gear drives the transmission gear to rotate, the upper gear of the adjacent other box-type unit will be driven, and then drive the two chains of the box-type unit, so that when any drawer-type box body is opened, the two drawer-type box bodies of the other box-type unit can be opened at the same time.

[0013] 3. A horizontal isolation bar is installed at the top of the inner box. It features a through-hole above each transmission gear. A slider and rail are located at the end of the isolation bar on one side of the through-hole, while a baffle is located at the end of the isolation bar on the other side. When the slider blocks the through-hole and abuts the baffle, the transmission mechanism's spring is compressed, allowing the transmission gear to engage simultaneously with the two upper gears on either side. When the slider is not blocking the through-hole, the spring is uncompressed, and the transmission gear is separated from the upper gears. This allows for simultaneous control of the opening of different cassette units.

[0014] 4. Two-way drawer-type box units can be set up in multiple groups and assembled in batches according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0023] A drawer-type packaging box that can be opened in multiple directions at the same time, comprising at least an outer shell and an inner box, such as Figure 1 and Figure 2 As shown, the outer shell is composed of a front plate 1, a top plate 2, a back plate 3, and a bottom plate 4, which are connected in sequence. The bottom plate can be the same size as the top plate or larger. If the bottom plate is larger than the top plate, the excess portion is designed to bend upward to ensure that the outer shell can form a complete frame. The inner box is divided into an upper part and a lower part. The lower part of the inner box is composed of multiple two-way drawer-type box units 5 arranged in parallel. Each two-way drawer-type box unit includes two drawer-type box bodies 6 with opposite openings and a push-pull mechanism located at the bottom of the two drawer-type box bodies. Each drawer-type box body is provided with a protruding pull ring or pull rope 7 on the surface where its opening is located. A support column 8 is also provided between each two adjacent two-way drawer-type box units. The height of the support column is equal to the distance between the bottom surface of the upper part of the inner box and the bottom plate of the outer shell.

[0024] like Figure 4As shown, the push-pull mechanism includes two chains 9 fixed to the bottom of the drawer-type box body and a double-layer gear located in the middle of the bottom of the two drawer-type box bodies. The double-layer gear is an integrated structure consisting of an upper gear 10 with a smaller diameter and a lower gear 11 with a larger diameter. The lower gear is engaged with the two chains at the same time, and the two chains are distributed on both sides of the lower gear. Since the two chains are fixed to the bottom of the two drawer-type boxes, when a pull ring or a pull rope is used to open any drawer-type box body, the chain will drive the lower gear to rotate, and the rotation of the lower gear will drive the chain on the other side, so the opposite drawer-type box body will be opened at the same time.

[0025] A transmission mechanism is provided in the middle between each two adjacent two-way drawer-type box units. The main view of the transmission mechanism and the two adjacent push-pull mechanisms is as shown in FIG. Figure 5 As shown, the transmission mechanism includes a spring 12 fixed to the bottom plate of the housing and a transmission gear 13 fixed to the upper end of the spring. The diameter of the transmission gear matches the spacing between the two upper gears on both sides. When the spring is compressed, the transmission gear and the two upper gears on both sides are meshed at the same time. When the spring is not compressed, the transmission gear and the upper gears are separated. Because the upper gear and the lower gear rotate synchronously, when one upper gear drives the transmission gear to rotate, the upper gear of the adjacent box-type unit will be driven, and then the two chains of the box-type unit will be driven, so that when any drawer-type box body is opened, the two drawer-type box bodies of the other box-type unit can be opened at the same time.

[0026] The top view of the bottom plate of the housing is as follows Figure 3 As shown, the bottom plate below each chain position is provided with a slide groove 14 to provide and limit the sliding position of the chain, the bottom plate below each double-layer gear position is provided with a gear mounting position 15 to fix the position of the double-layer gear, and the bottom plate below each spring position is provided with a spring mounting position 16 to fix the position of the spring.

[0027] The upper part 17 of the inner box is provided with an isolation bar 18, and the isolation bar is provided with a through hole 19 above the position of each transmission gear. The diameter of the through hole matches the diameter of the transmission gear. The end of the isolation bar on one side of the through hole is provided with a slider 20 and a slide rail, and the end of the isolation bar on the other side is a baffle. The length of the slider and the slide rail is greater than the diameter of the through hole. Figure 1 All the drawer-type boxes are opened at the same time, and the slider slides to block the through hole. The spring of the transmission mechanism is in a compressed state, which allows the transmission gear to engage with the two upper gears on both sides at the same time. At this time, the opening of different box-type units can be controlled at the same time. Figure 2 The middle drawer-type box body is not opened and the slider does not block the through hole, the spring is not compressed, the transmission gear is separated from the upper gear and extends above the through hole. At this time, different box-type units cannot be controlled to open at the same time.

[0028] Moreover, the shape and size of the drawer-type box body must be designed so as not to affect the space required for the transmission gear to move up and down when the spring is compressed.

[0029] Moreover, a magnetic sheet is provided on one side of the upper part of the inner box close to the front plate of the outer shell, or a magnetic sheet is provided on the excess part when the bottom plate size is larger than the top plate size, and a magnet is provided on the front plate of the outer shell to match the magnetic sheet, so as to facilitate closing of the outer shell.

[0030] Moreover, the two-way drawer-type box-type units can be arranged in multiple groups in parallel and assembled in batches according to actual needs. It is only necessary to design the size of the bottom plate according to the number of two-way drawer-type box-type units to be assembled.

[0031] Furthermore, the sides of the two outermost two-way drawer-type box units may be provided with side panels 21 to prevent foreign matter from entering the space where the push-pull mechanism and the transmission mechanism are located from the side.

[0032] Moreover, the height of the double-layer gear must be lower than the distance between the bottom surface of the upper part of the inner box and the bottom plate of the outer shell. When the spring is compressed, the height of the transmission mechanism must be lower than the distance between the bottom surface of the upper part of the inner box and the bottom plate of the outer shell.

[0033] Compared with the existing technology, the beneficial effects of this technical solution are:

[0034] 1. The push-pull mechanism at the bottom of the two drawer-type boxes includes two chains fixed to the bottom of the drawer-type boxes and a double-layer gear located in the middle of the bottom of the two drawer-type boxes. The lower gear is engaged with the two chains at the same time and the two chains are distributed on both sides of the lower gear. When a pull ring or a pull rope is used to open any drawer-type box, the chain will drive the lower gear to rotate, and the rotation of the lower gear will drive the chain on the other side. Since the chain is fixed to the bottom of the drawer-type box, the opposite drawer-type box will be opened at the same time.

[0035] 2. A transmission mechanism is provided in the middle between every two adjacent two-way drawer-type box-type units. When the spring is compressed, the transmission gear engages with the two upper gears on both sides at the same time. Since the upper gear and the lower gear rotate synchronously, when one upper gear drives the transmission gear to rotate, the upper gear of the adjacent other box-type unit will be driven, and then drive the two chains of the box-type unit, so that when any drawer-type box body is opened, the two drawer-type box bodies of the other box-type unit can be opened at the same time.

[0036] 3. A horizontal isolation bar is installed at the top of the inner box. It features a through-hole above each transmission gear. A slider and rail are located at the end of the isolation bar on one side of the through-hole, while a baffle is located at the end of the isolation bar on the other side. When the slider blocks the through-hole and abuts the baffle, the transmission mechanism's spring is compressed, allowing the transmission gear to engage simultaneously with the two upper gears on either side. When the slider is not blocking the through-hole, the spring is uncompressed, and the transmission gear is separated from the upper gears. This allows for simultaneous control of the opening of different cassette units.

[0037] 4. Two-way drawer-type box units can be set up in multiple groups and assembled in batches according to actual needs.
