Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a synchronously opening box body. Background Technology

[0002] Currently, many wine packaging boxes have an opening at the top for inserting and removing the bottle. Because the opening is small, removing the bottle is inconvenient and increases the risk of breakage. Furthermore, many high-end wine bottles have increasingly complex shapes, such as narrower ends and a bulging middle. Traditional packaging boxes are not ideal for securing these bottles from all angles; some can only secure half the bottle, resulting in poor stability. Others use foam padding for full securing, which also makes bottle removal difficult. Additionally, storing bottles in boxes is not ideal for display, and repeatedly removing and placing them increases the risk of breakage. Therefore, it is necessary to research a packaging box that can secure the bottle from all angles, facilitate easy removal, and also improve display. Utility Model Content

[0003] To overcome the aforementioned shortcomings of existing wine bottle packaging boxes, the technical problem to be solved by this utility model is to provide a synchronously opening box that can fix the wine bottle in all directions, facilitate its removal and display.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A synchronous split-opening box includes a support frame and a left half-box and a right half-box symmetrically and slidably disposed on the left and right sides of the support frame. The bottom of the support frame is provided with a synchronous sliding mechanism, which includes a slide rail, a gear rotatably connected to the bottom of the support frame, and two racks meshing with the gear. The two racks are symmetrically arranged about 180° around the gear axis. The length direction of the slide rail and the two racks are parallel to the sliding direction of the left half-box and the right half-box. The bottom of the left half-box and the right half-box is provided with guide members that slide with the slide rail. The two racks are respectively fixed on the guide members of the left half-box and the right half-box.

[0006] Furthermore, the support frame includes a top plate, a bottom plate, and multiple columns connecting the top plate and the bottom plate. The columns are connected to the top plate and the bottom plate by L-shaped connectors and bolts, and the synchronous sliding mechanism is set on the bottom plate.

[0007] Furthermore, the base plate of the support frame is also provided with a base, the synchronous sliding mechanism is located below the base, the positioning groove for fixing the product is provided above the base, the left half box and the right half box are provided with buffers, the two buffers are provided with a fixing groove adapted to the product contour on one side opposite to each other, and the top of the buffers is provided with a receiving groove.

[0008] Furthermore, both racks have a bent portion at the end near the gear, and the base plate has a limiting post. When the left and right racks slide to their respective extreme positions, the bent portion contacts the limiting post, preventing the two racks from moving outwards.

[0009] Furthermore, the top of both the left and right halves of the box is provided with guide posts, and the bottom of the top plate of the support frame is provided with guide grooves. The guide posts are slidably disposed in the guide grooves. When the left and right racks slide to their respective extreme positions, the guide posts contact the two ends of the guide grooves.

[0010] Furthermore, the bottom plate of the support frame is provided with two slide rails, and the bottom of both the left and right half boxes are provided with two guide slides, which are slidably connected to the two slide rails respectively.

[0011] Furthermore, the tops of the left and right half-boxes are also equipped with rollers, and the tops of the left and right half-boxes are slidably connected to the bottom of the top plate via the rollers.

[0012] Furthermore, a pull ring is provided on the opposite side of the left and right halves of the box, and a latch is provided on the side of the joint between the left and right halves of the box.

[0013] Furthermore, the latch includes a left fixing plate and a right fixing plate respectively disposed on the left half box and the right half box. The left fixing plate is provided with a first buckle, and the right fixing plate is provided with a cover plate. The middle part of the cover plate is hinged to the right fixing plate, and a torsion spring is provided at the hinge. The inner side of the cover plate near the left fixing plate is provided with a second buckle. Under the action of the torsion spring, the cover plate causes the second buckle to engage with the first buckle.

[0014] Furthermore, the left and right fixing plates are provided with positioning pins and positioning holes that can be inserted into each other on opposite sides.

[0015] The beneficial effects of this utility model are: the entire box is divided into a left half and a right half that open from left to right, and the left half and the right half are slidably connected to the support frame by a synchronous sliding mechanism, so that the left half and the right half can open to the sides and close to the center at the same time, thereby achieving the purpose of fixing the product placed in the support frame in all directions, and also facilitating the picking up, placing and displaying of the product.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these are used to describe the relative positional relationships between components and are not specific references to the absolute positions of related components or the positional relationships between components. They are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity, such as "many," "multiple," or "several," these specifically refer to two or more.

[0026] like Figure 1 , Figure 2 , Figure 5As shown, the present invention provides a synchronously opening box body, including a support frame 1 and a left half box 2 and a right half box 3 symmetrically and slidably arranged on the left and right sides of the support frame 1. A synchronous sliding mechanism 4 is provided at the bottom of the support frame 1. The synchronous sliding mechanism 4 includes a slide rail 41, a gear 42 rotatably connected to the bottom of the support frame 1, and two racks 43 meshing with the gear 42. The two racks 43 are symmetrically arranged at a 180° rotational angle around the axis of rotation of the gear 42. The length directions of the slide rail 41 and the two racks 43 are parallel to the sliding directions of the left half box 2 and the right half box 3. Guide members 44 that slidably engage with the slide rail 41 are provided at the bottom of the left half box 2 and the right half box 3. The two racks 43 are respectively fixed to the guide members 44 of the left half box 2 and the right half box 3. The sliding directions of the left half box 2 and the right half box 3 are preferably perpendicular to their mating surfaces, facilitating the fixing and handling of the product 6. The meshing structure of gear 42 and two racks 43 allows the two racks 43 to move synchronously towards each other or away from each other, thereby realizing the opening and closing of the left half box 2 and the right half box 3. In practical applications, the packaged product 6 can be placed inside the support frame 1, and then the left half box 2 and the right half box 3 can be used to fix the product 6 from both sides, thereby ensuring the stability of the product 6 placed inside the box. To display or remove the product, simply push the left half box 2 and the right half box 3 to the sides, which is convenient and quick.

[0027] Since the entire box body relies primarily on the supporting frame 1 as its structural skeleton, it is essential to ensure sufficient structural strength and stability. A preferred structure of this invention comprises a top plate 11, a bottom plate 12, and multiple uprights 13 connecting the top plate 11 and the bottom plate 12. The uprights 13 are connected to the top plate 11 and the bottom plate 12 via L-shaped connectors 14 and bolts. The synchronous sliding mechanism 4 is mounted on the bottom plate 12. Preferably, the uprights 13 and the L-shaped connectors 14 are made of metal to enhance structural strength. The entire box body can be rectangular, with four uprights 13 positioned along the four edges. The lengths of the top plate 11 and the bottom plate 12 are preferably the same as the sum of the lengths of the left half of the box 2 and the right half of the box 3, which improves the overall integrity and aesthetic appearance of the box body.

[0028] To facilitate the fixing of product 6 and conceal the synchronous sliding mechanism 4, a preferred embodiment is that the base plate 12 of the support frame 1 is also provided with a base 5, the synchronous sliding mechanism 4 is located below the base 5, and a positioning groove 51 for fixing product 6 is provided above the base 5. Buffer members 7 are provided inside the left half-box 2 and the right half-box 3. A fixing groove 71 adapted to the contour of product 6 is provided on one side of each buffer member 7, and a receiving groove 72 is provided on the top of the buffer member 7. The positioning groove 51 adapts to the bottom structure of product 6 and can position product 6 placed inside. The fixing groove 71 adapts to the shape contour of the left and right sides of product 6, preferably slightly larger than the product contour, so that there is a gap fit between it and the product, avoiding uneven friction on the left and right sides of product 6 during opening the box, which could cause product 6 to tilt. The receiving groove 72 can be used to place other small items such as wine glasses 9. To avoid interference between the guide slide 44 and the base 5, the guide slide 44 can be set in an L-shape, such as... Figure 3 As shown, the guide slide 44 is inserted from both ends of the base 5 and connected to the slide rail 41 and the rack 43.

[0029] When sliding the left half-box 2 and the right half-box 3, their range of movement needs to be limited. When they close, this can be achieved by their docking; when they open, this can be achieved by setting a limiting structure between the support frame 1 and the left half-box 2 and the right half-box 3. The preferred embodiment of this invention is that a bent portion 45 is provided at one end of each rack 43 near the gear 42, and a limiting post 46 is provided on the base plate 12. When the left and right racks 43 slide to their respective extreme positions, the bent portion 45 contacts the limiting post 46, preventing the racks 43 from moving further outward. Using the limiting post 46 to directly limit the racks 43 improves the stability and accuracy of the limiting, effectively preventing the racks 43 from disengaging from the gear 42.

[0030] Limiting the rack 43 only restricts the bottom of the left half of box 2 and the right half of box 3. Uneven force on the upper and lower parts of the box may cause it to wobble or deform. Therefore, a further solution is, such as Figure 4 As shown, both the left half-box 2 and the right half-box 3 are equipped with guide posts 31 at their tops, and the top plate 11 of the support frame 1 is equipped with a guide groove 15 at its bottom. The guide posts 31 are slidably disposed within the guide grooves 15. When the left and right racks 43 slide to their respective extreme positions, the guide posts 31 contact the two ends of the guide grooves 15. This allows for guidance and limitation of both the upper and lower ends of the left half-box 2 and the right half-box 3, improving the reliability of the sliding limitation of the left half-box 2 and the right half-box 3.

[0031] In addition, to ensure smooth sliding of the left half-box 2 and the right half-box 3, two slide rails 41 are provided on the base plate 12 of the support frame 1, and two guide slides 44 are provided at the bottom of both the left half-box 2 and the right half-box 3. The two guide slides 44 are slidably connected to the two slide rails 41 respectively. Rollers 32 are also provided at the top of the left half-box 2 and the right half-box 3, and the top of the left half-box 2 and the right half-box 3 are slidably connected to the bottom of the top plate 11 through the rollers 32. This ensures the smoothness and stability of the sliding of the left half-box 2 and the right half-box 3.

[0032] Furthermore, to improve the ease of opening and closing the box, a pull ring 33 is provided on each of the opposite sides of the left half box 2 and the right half box 3. To close the box, a latch 8 is provided on the side of the joint between the left half box 2 and the right half box 3.

[0033] The latch 8 can be adopted as follows: Figure 5 The structure shown includes a left fixing plate 81 and a right fixing plate 82 respectively disposed on the left half box 2 and the right half box 3. The left fixing plate 81 has a first latch 83, and the right fixing plate 82 has a cover plate 84. The cover plate 84 is hinged to the right fixing plate 82 at its center, and a torsion spring 85 is provided at the hinge. A second latch 86 is provided on the inner side of the cover plate 84 near the left fixing plate 81. In its natural state, the cover plate 84, under the action of the torsion spring 85, engages the second latch 86 with the first latch 83. The opposite sides of the first latch 83 and the second latch 86 have a wedge-shaped structure, allowing the first latch 83 and the second latch 86 to engage when the left half box 2 and the right half box 3 are closed. When it is necessary to open the box, simply press the end of the cover plate 84 away from the left fixing plate 81 to lift the cover plate 84, disengaging the first latch 83 from the second latch 86. Then, pull the left half box 2 or the right half box 3 outwards. In addition, to prevent misalignment of the left fixing plate 81 and the right fixing plate 82 from causing the latch 8 to fail, positioning pins 87 and positioning holes 88 that can be inserted into each other are provided on the opposite side of the left fixing plate 81 and the right fixing plate 82. Figure 6 As shown, when the first latch 83 and the second latch 86 are engaged, the positioning post 87 is inserted into the positioning hole 88, which ensures the reliability of the engagement between the first latch 83 and the second latch 86.
