The self-adsorption box includes a box body with an adsorption tray assembly placed therein, the adsorption tray assembly includes a bottom plate, a mesh sheet stacked on the bottom plate, and a film covering the mesh sheet, the film is bonded to the bottom plate on all sides, and an air hole is opened in the middle of the bottom plate; the box body is composed of an upper cover and a lower cover, the upper cover and the lower cover are hinged together at the rear side, and the upper cover and the lower cover are provided with a buckle structure at the front side, and the inner side of the upper cover is provided with a limit pressure block for pressing down the side of the bottom plate, the limit pressure block is located on the inner side of the two sides of the upper cover, the limit pressure block extends from the lower side of the upper cover, and the outer side of the extended part of the limit pressure block is an inclined surface; two limit pressure blocks are provided on both sides of the upper cover, one in front and one in the back, and the length and width of the box body are slightly larger than the length and width of the bottom plate of the adsorption tray assembly. The patent is easy to use, convenient for the storage and transportation of tiny electronic parts, can well protect electronic parts, avoid damage during transportation, and is safe and reliable.

[0006] However, in the above patent, since the inner length and width of the box body are slightly larger than the bottom length and width of the adsorption tray assembly, and the limiting block only limits the adsorption tray assembly from above, the adsorption tray assembly is prone to shaking in the front, back, left and right directions during actual transportation, which easily affects the firmness of the electronic parts adhering to the film. Therefore, it is necessary to improve this technical problem, and this case is born. Utility model content:

[0008] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a plastic vacuum box structure with reasonable design to reduce the shaking of the adsorption tray assembly during transportation.

[0009] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a plastic vacuum box structure, including a box body with an adsorption tray assembly placed thereon, the adsorption tray assembly including a bottom plate, a mesh stacked on the bottom plate, and a film covering the mesh, the film being bonded to the bottom plate on all sides, the box body consisting of an upper cover and a lower cover, the upper cover and the lower cover being hinged together at the rear sides, the sides of the bottom plate being provided with limiting grooves, the inner sides of the upper cover being provided with limiting pressure blocks which are used to extend downward into the limiting slots and press the bottom of the limiting slots.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] like Figures 1 to 7 As shown, the utility model is a plastic vacuum box structure, which is improved on the basis of the self-adsorption box for easy transportation disclosed in Chinese patent publication No. CN215157545U. The structure includes a box body 1 on which an adsorption tray assembly 2 is placed, and the adsorption tray assembly 2 includes a bottom plate 3, a mesh 4 stacked on the bottom plate 3, and a film 5 covering the mesh 4, and the film 5 is bonded to the bottom plate 3 on all sides. The box body 1 is composed of an upper cover 6 and a lower cover 7, and the upper cover 6 and the lower cover 7 are hinged together at the rear sides. The specific improvement is that: limiting grooves 8 are arranged on the sides of the bottom plate 3, and limiting pressure blocks 9 are arranged on the inner sides of the upper cover 6, and the position of the limiting pressure blocks 9 corresponds to the position of the limiting grooves 8. The limiting pressure blocks 9 are used to extend downward into the limiting slots 8 and press the bottom of the limiting slots 8. By arranging limiting pressure blocks on the inner sides of the sides of the upper cover and limiting grooves on the sides of the bottom of the adsorption tray assembly, the limiting pressure blocks are extended into the limiting grooves, and the limiting pressure blocks on all sides can limit the adsorption tray assembly from the front, back, left and right directions, thereby effectively reducing the shaking of the adsorption tray assembly from the front, back, left and right directions in the box body during transportation.

[0028] In this embodiment, two limiting grooves 8 are arranged on the four sides of the bottom plate 3, that is, two limiting grooves are arranged on each side, and there are eight limiting grooves in total on the bottom plate, and the two limiting grooves 8 are spaced apart along the length direction of the side of the bottom plate 3. Two limiting pressing blocks 9 are also arranged on the four sides of the upper cover 6, and the positions of the limiting pressing blocks 9 correspond to the positions of the limiting grooves, that is, two limiting pressing blocks are arranged on the inner side of each side of the upper cover, and there are eight limiting pressing blocks on the upper cover in total.

[0029] In this embodiment, the shape of the limiting pressing block 9 is adapted to the shape of the limiting groove 8. The length and width of the cross section of the limiting pressing block are slightly larger than the length and width of the limiting groove, for example, 0.8-1.5 mm larger.

[0030] In this embodiment, the limiting pressing block 8 extends out from the lower side of the upper cover 6 .

[0031] In another embodiment, in order to improve the overall sealing effect, upper sealing sheets 10 are fixed to the bottom surfaces of the four sides of the upper cover 6, and lower sealing sheets 11 for contacting the upper sealing sheets 10 are fixed to the top surfaces of the four sides of the lower cover 7. When the box body is closed, the upper cover is placed on the lower cover, and the upper sealing sheet contacts the lower sealing sheet to improve the sealing effect between the upper and lower covers. Preferably, the upper and lower sealing sheets can be made of rubber material.

[0032] In another embodiment, the outer ends of the upper sealing sheet 10 and the lower sealing sheet 11 extend outward, the extended end of the upper sealing sheet is folded upward and fits against the outer side surface of the upper cover, and the extended end of the lower sealing sheet is folded downward and fits against the outer side surface of the lower cover.

[0033] In another embodiment, the top corner of the left rear end of the bottom plate 3 is provided with an anti-fool chamfer 12; the top corner of the left rear end of the lower cover 7 is provided with a right-angled triangle-shaped positioning block 13, the position of the positioning block 13 corresponds to the position of the anti-fool chamfer 12, and the inclined surface of the positioning block is parallel to the inclined surface of the anti-fool chamfer. By providing the anti-fool chamfer and the right-angled triangle-shaped positioning block, it is ensured that the adsorption tray assembly can be accurately placed in the box body, and the positioning effect of the box body is improved.

[0034] It should be noted that, compared with the self-adsorption box for easy transportation disclosed in Chinese Patent Publication No. CN215157545U, this embodiment only increases the number and distribution of limiting pressure blocks, sets limiting grooves on the bottom plate, sets anti-fool chamfers and positioning blocks, sets upper sealing plates and lower sealing plates, and other undisclosed structures are the same as those of the self-adsorption box for easy transportation disclosed in Chinese Patent Publication No. CN215157545U, such as the snap-fit ​​structure between the upper cover and the lower cover, etc., and will not be repeated here.

[0035] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0036] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0037] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
