Description

Technical Field

[0001] The present invention relates to the technical field of prism production, processing, packaging and turnover, and in particular to a packaging structure for edge-contact triangular prisms. Background Art

[0002] The design of the prism packaging box needs to take into account the precision, fragility and protection needs of the prism to ensure that the prism is not damaged during transportation, storage and handling.

[0003] After searching, patent application number CN202022029957.2 discloses a prism packaging box. The prism packaging box includes a base and a cover. The base includes: a base; a plurality of first protrusions, wherein the plurality of first protrusions are arranged in multiple rows on the base along a first direction; and a plurality of second protrusions, wherein the plurality of second protrusions are arranged in multiple rows on the base along a second direction. The plurality of second protrusions are arranged on the base at intervals from the plurality of first protrusions, such that two adjacent first protrusions and two adjacent second protrusions form a cavity for accommodating a prism. The cover is arranged opposite the base. The cover includes: a base plate; a positioning slot, which is arranged on the base plate along the second direction and corresponds to a row of the plurality of second protrusions in the second direction; and a plurality of arc-shaped protrusions, which are arranged at intervals on the positioning slot, such that each arc-shaped protrusion corresponds to each cavity.

[0004] Currently, prism packaging uses a point contact design. The bearing points on the packaging board bear the large flat surface of the hypotenuse of the prism. During the turnover and transportation process, the contact points come into contact with the prism plane, resulting in point scratches and dirt, causing defects. In addition, this type of board design cannot be inverted, and the four-point contact is prone to tilting and misplacement when placed. When using a packaging board with four-point contact, the large flat surface of the prism is seriously contaminated. In addition, the mainstream prism packaging structure uses two mounting plates with limited bearing points to clamp it to prevent it from being shaken out of the mounting position. However, the connection structure between the two mounting plates is relatively cumbersome, and tools are required to separate the two mounting plates before the prism can be removed. Therefore, we need to propose a packaging structure for edge-contact prisms. Summary of the Invention

[0005] The object of the present invention is to provide a packaging structure for edge-contact prisms. Through the design of the support platform, the first slope, the second slope, and the third slope on the base plate, the edge of the prism contacts the packaging board. The surface and corner of the prism will not contact the packaging board regardless of tilting or shaking. The design of the inclined surface of the packaging board contact edge improves the matching gap between the packaging board and the product, and at the same time facilitates placement, it also leaves less room for product shaking. The base plate and the cover plate can be tilted against each other, which can more conveniently realize large-scale inspection without the need for additional design inspection. Through the design of the clamping fixture, after the prism is installed between the two mounting plates, the two mounting plates can be locked to prevent it from being shaken out of the mounting position. The clamping fixture has a reasonable structure and can be installed and disassembled without the aid of external tools, making it easy to remove the prism from between the base plate and the cover plate, so as to solve the problems raised in the above-mentioned background technology.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-14 The present invention provides a technical solution: a packaging structure for an edge-contact prism, comprising:

[0040] The bottom plate 1 is provided with a plurality of first through holes 101 arranged in a matrix. A first mounting frame 100 arranged around the first through holes 101 is installed on the bottom plate 1. The first mounting frame 100 is integrally formed with supporting platforms 102 arranged opposite to each other, and each position corresponding to the first through hole 101 is equipped with two supporting platforms 102 arranged opposite to each other. Figure 4 As shown, the upper surface of the support platform 102 is provided with a first slope 103, and the first mounting frame 100 is further provided with a second slope 104 that docks with the first slope 103. The second slope 104 is located on both sides of the higher end of the first slope 103;

[0041] The cover plate 2 is covered on the bottom plate 1, and a plurality of second through holes 201 are formed on the cover plate 2, which are aligned with the first through holes 101. The design of the first through holes 101 and the second through holes 201 makes the bottom plate 1 and the cover plate 2 hollow. The bottom plate 1 and the cover plate 2 are also provided with drainage grooves to ensure that the prisms can be properly cleaned and dried in the packaging board.

[0042] like Figure 6 、 Figure 7 As shown, a second mounting bracket 200 is provided on the cover plate 2, and protrusions 202 are integrally formed at the four corners of the second mounting bracket 200, and a third slope 203 aligned with the inclined side edge of the prism is provided on one corner of the protrusion 202;

[0043] The angle between the two first slopes 103 opposite to each other is 150°, the angle between the two second slopes 104 opposite to each other is 30°, the gap between the four third slopes 203 and the four side edges of the prism is 0.1-0.2mm, and the angle between the third slope 203 and the side surface of the prism is 45°.

[0044] To address the contamination caused by point contact with the surface, we addressed the contact location. The prisms should not be in full contact, as this would affect the surface quality. Through discussion and verification, we decided to change the prism's edge to contact with the packaging board, leaving other areas and positions clear. This ensures placement while allowing the board to be flipped over for cleaning without contacting any side of the prism.

[0045] Packaging board bottom plate 1: The prism has a large inclined surface facing downward. When designing the packaging board, the two cutting edges of the large surface are in contact with the packaging board. The supporting surface of the packaging board is designed at a certain angle to ensure that the flat surface does not touch the packaging board when the prism is placed. Only the edges are in contact, and the prism is supported on both sides, with no space in the middle, which can ensure the placement effect of the prism.

[0046] Packaging board cover 2: Designed so that the prism's right-angled edges contact cover 2, cover 2 features a third slope 203 at the same angle at the point where the prism's right-angled edges meet, ensuring that the prism's corners don't contact the packaging board and cause corner collapse. During inversion, all four prism edges contact third slope 203, preventing displacement and effectively positioning the prism. After inversion, the prism remains flat, with the large, flat beveled edge facing upward, allowing for normal inspection. After inspection, it can be returned to its original position.

[0047] When the bottom cover of the packaging board is closed, the prism gap is only 0.1mm, ensuring that the prism has little room to move inside the packaging board and will not cause defects such as broken edges and corners due to shaking.

[0048] The bottom cover of the packaging board is designed with large hollow spaces and drainage grooves to ensure that the prisms can be cleaned and dried normally inside the packaging board.

[0049] In this embodiment, the edges of the prisms contact the packaging board. The faces and corners of the prisms will not contact the packaging board regardless of tilt or shaking. The inclined design of the packaging board contact edge improves the clearance between the packaging board and the product, making it easier to place and leaving less room for product shaking. In addition, the bottom plate and cover plate can be reversed, making it easier to implement large-scale inspection without the need for additional design to inspect the reversed plate.

[0050] After using the packaging board with a new structure (bottom plate 1 and cover plate 2), the cleaning, inspection and turnover are integrated, and the defects such as dirt, broken edges and broken corners on the contact surface between the prism and the packaging board are completely improved.

[0051] When in use, the prism is placed above the first through hole 101 on the base plate 1, with the large flat surface of the bottom surface of the prism facing downward, and the edges of the bottom surface of the prism respectively abutting against the first slope 103 and the second slope 104, so that the bottom surface of the prism is in edge contact with the base plate 1. After the base plate 1 is full of prisms, the cover plate 2 is closed on the base plate 1, and the top of the prism is aligned with the second through hole 201, and the inclined side edges of the prism are aligned with the third slope 203, so that the gap between the four third slopes 203 and the four side edges of the prism is 0.1-0.2mm, and the angle between the third slope 203 and the side surface of the prism is 45°, ensuring that the prism has little room for movement in the packaging board and will not cause defects such as broken edges and corners due to shaking;

[0052] Example 2

[0053] In order to enhance the stability of the prism installation, the bottom plate 1 and the cover plate 2 need to be connected to prevent the prism from being separated or deviated due to bumps during transportation. This embodiment adds a structure for connecting the bottom plate 1 and the cover plate 2, that is, the device further includes:

[0054] Two L-shaped clips 5 are used to connect the base plate 1 and the cover plate 2. The two clips 5 are used as a group. Two groups of clips 5 are installed on the non-adjacent two sides of the base plate 1 and the cover plate 2 respectively. The two clips 5 are movably connected by a limiting mechanism 6. The limiting mechanism 6 is set to adjust the distance between the two clips 5 so that it is suitable for base plates 1 and cover plates 2 of different thicknesses.

[0055] Both the base plate 1 and the cover plate 2 are provided with a connecting groove 3 for accommodating the clip 5. The depth of the connecting groove 3 is the same as the thickness of the base plate 1 and the cover plate 2 to ensure the aesthetics of the clip 5 after installation. A first groove 4 is provided at the bottom of the connecting groove 3, and an installation groove 51 is provided on the inner wall of the clip 5. A locking mechanism 7 that is engaged with the inside of the first groove 4 is movably provided inside the installation groove 51. A locking mechanism 8 for locking the base plate 1 and the cover plate 2 is also installed on the clip 5.

[0056] The snap-fit ​​mechanism 7 is the first safeguard to ensure the connection stability between the base plate 1 and the cover plate 2, and the locking mechanism 8 is the second safeguard to ensure the connection stability between the base plate 1 and the cover plate 2, which greatly improves the connection stability between the base plate 1 and the cover plate 2.

[0057] The limiting mechanism 6 includes a connecting plate 61 connected to the upper clamping member 5, a plug post 62 is connected to the connecting plate 61, a limiting sleeve 64 is connected to the lower clamping member 5, and the bottom end of the plug post 62 passes through the limiting sleeve 64 and is connected to a limiting ring 63 to prevent the plug post 62 from detaching.

[0058] The bottom of the upper clamping member 5 is connected to a sleeve 66 , and the lower clamping member 5 is provided with a second groove 67 . A first spring 65 is connected between the bottom of the second groove 67 and the inner top of the sleeve 66 .

[0059] When the thickness of the base plate 1 and the cover plate 2 is relatively thick, when installing the clamping member 5, the distance between the two clamping members 5 is pulled apart during the process from the pressure plate 71 contacting the side of the connecting groove 3 to entering the interior of the connecting groove 3, causing the plug 62 to slide upward inside the limiting sleeve 64 and the first spring 65 to be stretched.

[0060] The locking mechanism 7 includes a pressure plate 71 movably installed inside the mounting groove 51, the side of the pressure plate 71 is connected to a first slider 72, the inner wall of the mounting groove 51 is provided with a first slide groove 52, the first slider 72 is slidably installed inside the first slide groove 52, and a second spring 73 is connected between the top of the pressure plate 71 and the inner top of the first slide groove 52.

[0061] The two clamping members 5 are respectively inserted into the interior of the two connecting grooves 3. During this process, the pressure plate 71 in the locking mechanism 7 first contacts the side of the connecting groove 3, and the pressure plate 71 moves up to squeeze the second spring 73, and the first slider 72 moves inside the first slide groove 52 until the pressure plate 71 fits against the inner wall of the connecting groove 3, and then the pressure plate 71 moves inside the connecting groove 3.

[0062] A circular limiting groove 53 is formed on the inner wall of the clamping member 5 . An accommodating cavity 54 communicating with the limiting groove 53 is provided inside the clamping member 5 . A through hole 56 communicating with the accommodating cavity 54 is formed on the surface of the clamping member 5 .

[0063] The locking mechanism 8 includes a positioning post 81 that is vertically slidably mounted in the limiting groove 53, a push block 84 that is horizontally slidably mounted in the accommodating cavity 54, and a guide post 89 that is vertically slidably mounted in the through hole 56. The position of the guide post 89 is aligned with the position of the push block 84.

[0064] The bottom side of the positioning column 81 is provided with a circular chamfer to facilitate the positioning column 81 to enter the connecting groove 3. One end of the push block 84 is provided with an inclined surface, and a ball is movably mounted on the bottom of the guide column 89. The ball at the bottom of the guide column 89 abuts against the inclined surface of the push block 84, driving the push block 84 to move.

[0065] A third spring 82 is connected between the top of the positioning column 81 and the inner top of the limiting groove 53. A notch 83 with a triangular cross-section is provided on the outer wall of the positioning column 81. A positioning groove 41 corresponding to the positioning column 81 is provided at the bottom of the connecting groove 3. The other end of the push block 84 is connected to a U-shaped connecting frame 86, and a rotating column 87 aligned with the notch 83 is rotatably installed on the connecting frame 86.

[0066] Pressing the pressing block 810 drives the guide column 89 and the first connecting ring 811 to move downward, the fourth spring 812 between the first connecting ring 811 and the second connecting ring 813 is compressed, and the ball at the bottom of the guide column 89 contacts the inclined surface of the push block 84. Under the action of the thrust, the push block 84 is pushed on the roller 88 to move toward the positioning column 81, thereby driving the rotating column 87 to contact the notch 83 on the positioning column 81. The positioning column 81 moves upward under the action of the extrusion force, so that the positioning column 81 disengages from the positioning groove 41.

[0067] The side of the push block 84 is connected to a second slider 85, and the inner wall of the accommodating chamber 54 is provided with a second slide groove 55. The second slider 85 is slidably installed inside the second slide groove 55. A roller 88 for supporting the push block 84 is also rotatably installed inside the accommodating chamber 54, which can make the movement process of the push block 84 smoother.

[0068] The top of the guide column 89 is connected to a pressing block 810, and the inside of the through hole 56 is respectively installed with a fixed second connecting ring 813 and a first connecting ring 811 that slides up and down. The bottom of the guide column 89 passes through the first connecting ring 811 and the second connecting ring 813, and the first connecting ring 811 is fixed on the outer wall of the guide column 89. A fourth spring 812 is connected between the first connecting ring 811 and the second connecting ring 813. After pressing the pressing block 810, the elastic force of the fourth spring 812 can automatically reset the pressing block 810 and the guide column 89.

[0069] When in use, after the prism is loaded, in order to ensure the installation stability of the prism between the base plate 1 and the cover plate 2, the clamping fixture 5 is required to connect and position the two. Specifically:

[0070] When the locking cam 71 is in the state of being pressed down, the locking cam 73 is in the state of being clamped in the locking cam 71, and the first and second locking cams 73 are in the state of being locked.

[0071] When the prism needs to be removed, the connection between the bottom plate 1 and the cover plate 2 is cancelled, and the fastener 5 is disassembled. The specific operation is as follows:

[0072] The pressing block 810 is pressed to drive the guide column 89 and the first connecting ring 811 to move downward, and the fourth spring 812 between the first connecting ring 811 and the second connecting ring 813 is compressed, and the ball at the bottom of the guide column 89 contacts the inclined surface of the push block 84. Under the action of the thrust, the push block 84 is pushed on the roller 88 to move toward the positioning column 81, thereby driving the rotating column 87 to contact the notch 83 on the positioning column 81 (since the cross-section of the notch 83 is triangular, the rotating column 87 contacts the inclined surface of the notch 83). The positioning column 81 moves upward under the action of the extrusion force, so that the positioning column 81 disengages from the positioning groove 41, and then the clamping member 5 is pulled outward, so that the pressure plate 71 also disengages from the first groove 4, and the clamping member 5 can be removed.

[0073] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
