[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0061] In the prior art, there is provided a packaging box stopper 1 and a packaging box 2 that can adapt the packaging box 2 to a variety of display panels 3 with different sizes by adjusting the position of the packaging box stopper 1, but no improvement has been made on the interference problem between the packaging box stopper 1 and the display panel 3.

[0062] Based on this, the embodiment of the present invention provides a packaging box stopper 1, as Figures 1 to 2 shown, Figure 1 which is a schematic structural diagram of the packaging box stopper provided by the embodiment of the present invention, Figure 2 and Figure 1 is a partial schematic diagram when the packaging box stopper in Figure 2, a fixing block 110, which is used to be embedded into the side wall 210 of the packaging box, so that the blocking block 1 is fixed on the inner side wall of the packaging box 2; the side surface of the supporting block 120 is fixedly connected with the fixing block 110, and the bottom surface is used to be mounted on the bottom wall 220 of the packaging box. A first connecting structure 121 is arranged at the top of the supporting block 120; the bottom of the blocking block 130 is hinged to the bottom of the supporting block 120, and the top is hinged to the first side 141 of the adjusting block 140 away from the fixing block 110; a plurality of second connecting structures 143 are arranged at the bottom of the adjusting block 140, and the plurality of second connecting structures 143 are arranged in parallel in sequence along the direction away from the fixing block 110; the plurality of second connecting structures 143 are used to cooperate with the first connecting structure 121 at the top of the supporting block 120 respectively, so as to adjust the distance between the top of the blocking block 130 and the top of the supporting block 120.

[0063] Specifically, before adjustment, as shown in Figure 1 and Figure 2 , the first connecting structure 121 cooperates with the second connecting structure 143 close to the second side 142 of the adjusting block. At this time, the blocking block 130 is in a state perpendicular to the bottom wall 220 of the packaging box; during adjustment, as shown in Figure 3 , Figure 3 is Figure 1 a schematic structural diagram during the adjustment of the adjusting block in the packaging box blocking block in Figure 4 . Lift the adjusting block 140 so that the first connecting structure 121 disengages from the second connecting structure 143; after adjustment, as shown in Figure 4 , Figure 4 is Figure 1 a schematic structural diagram when the blocking block in the packaging box blocking block is inclined. The first connecting structure 121 cooperates with the second connecting structure 143 close to the first side 141 of the adjusting block, so that the distance between the top of the supporting block 120 and the top of the blocking block 130 is shortened, thereby making the blocking block 130 form an inclined angle.

[0064] In this embodiment, by designing the connection between the supporting block 120 and the blocking block 130 of the packaging box blocking block 1 and between the blocking block 130 and the adjusting block 140 as a rotatable hinge structure, it is convenient to adjust the inclination angle of the packaging box blocking block 1, and a detachable connection is formed between each part, which is convenient for replacing key structures. At the same time, a first connecting structure 121 is arranged at the top of the supporting block 120, and a plurality of second connecting structures 143 matching with the first connecting structure 121 are arranged at the bottom of the adjusting block 140, so that the adjusting block 140 and the supporting block 120 can be fixedly connected through the first connecting structure 121 and the second connecting structure 143. The arrangement of the plurality of second connecting structures 143 provides multiple choices for the cooperation between the two. As shown in Figure 1 and Figure 3 , by adjusting the distance between the top of the blocking block 130 and the top of the supporting block 120, the blocking block 130 of the packaging box blocking block 1 can form an inclined angle.

[0065] Since there is an inclined angle between the blocking block 130 of the packaging box block 1 and the product, a gap is generated between the blocking block 130 and the product, which can effectively improve the problem of product breakage caused by interference due to direct contact between the packaging box block 1 and the product when the product is taken out during the turnover and transportation of the product and the process of putting it into the automated production line; thereby improving the yield rate of product manufacturing. Due to the increase in the yield rate, the production cost of product manufacturing is reduced, and the operating rate of the product production equipment is further improved.

[0066] In this embodiment, as Figure 2 shown, the fixing block 110 is used to be embedded into the side wall 210 of the packaging box. At the same time, the side surface of the supporting block 120 is fixedly connected to the fixing block 110, and the bottom surface is used to be installed on the bottom wall 220 of the packaging box, ensuring the stability of the packaging box block 1 during the turnover and transportation and the process of putting it into the production line, thereby realizing the fixing effect on the product. The blocking block of the packaging box block 1 provides a buffering effect for the product.

The fixing block 110 includes a vertical connecting plate 111 and a vertical fixing plate 112 connected in a T shape; one end of the vertical connecting plate 111 is fixedly connected to the vertical fixing plate 112, and the other end is fixedly connected to the side surface of the supporting block 120.In this embodiment, a first connection structure 121 is provided at the top of the support block side plate 122, and a fixed connection can be formed between the support block side plate 122 and the vertical connection plate 111 of the fixed block 110 by means of gluing or welding. To ensure that the connection between the two will not break or become detached due to external forces, the bonding strength between the support block side plate 122 and the fixed block 110 should be ≥ 15 Mpa (megapascals). At the same time, the vertical fixing plate 112 of the fixed block is used to provide a fixing function for the packaging box stopper 1 after the T-shaped fixed block 110 is embedded in the side wall 210 of the packaging box. The support block bottom plate 123 abuts against the bottom wall 220 of the packaging box, so that a more stable installation is formed between the support block 120 and the packaging box 2, effectively preventing the tipping of the packaging box stopper 1. In practical applications, the vertical fixing plate 112 and the vertical connection plate 111 of the fixed block 110 can be set as an integral structure or a split structure.

[0081] In this embodiment, the bottom of the baffle 131 is hinge-connected in a hinge-like manner to the side of the support block bottom plate 123 away from the fixed block 110 through the first hinge member 150A; the top of the baffle 131 is hinge-connected in a hinge-like manner to the first side 141 of the adjustment block 140 away from the fixed block 110 through the second hinge member 150B, which facilitates adjusting the inclination angle of the baffle 130. The first hinge member 150A and the second hinge member 150B are rotationally connected by a fixed rotation hole 151 and a fixed through rod 152. Among them, referring to Figure 12 , the fixed through rod 152 is fixed to the supplementary block 155, such that a gap is left between the fixed through rod 152 and the baffle 131, ensuring that the fixed through rod 152 can be inserted into the fixed rotation hole 151. The inner diameter of the fixed rotation hole 151 is 0.1 mm larger than the outer diameter of the fixed through rod 152, such that a clearance fit is formed between the fixed rotation hole 151 and the fixed through rod 152. At the same time, each set of the first hinge member 150A or the second hinge member 150B includes 2 - 4 fixed rotation holes 151 and fixed through rods 152 corresponding to each of the fixed rotation holes 151 one by one.

[0082] In this embodiment, the first hinge member 150A and the second hinge member 150B further include a locking groove 153 and a locking block 154. The locking groove 153 and the fixed rotation hole 151 are provided on the same structure, and the locking block 154 is provided on the supplementary block 155. As Figure 14 shown, when the first hinge member 150A and the second hinge member 150B rotate to a preset position, the locking block 154 is inserted into the locking groove 153, which is used to restrict the movement between the fixed rotation hole 151 and the fixed through rod 152 along the axial direction of the fixed through rod 152, thereby realizing the self-locking of the first hinge member 150A and the second hinge member 150B along the axial direction. In practical applications, the positions of the fixed rotation hole 151, the fixed through rod 152, the locking groove 153, and the locking block 154 can be adjusted as needed, as long as the rotatable hinge and self-locking of the first hinge member 150A and the second hinge member 150B can be realized.

[0083] The embodiment of the present utility model further provides a packaging material box 2. As Figures 15 to 17 shown, Figure 15 is the top view of the packaging material box provided by the embodiment of the present utility model, Figure 16 is the cross-sectional view when the packaging material box baffle in the packaging material box provided by the embodiment of the present utility model abuts against the display panel, Figure 17 is the cross-sectional view when there is an inclined angle between the packaging material box baffle and the display panel in the packaging material box provided by the embodiment of the present utility model. The packaging material box 2 includes a bottom wall 220 and four side walls 210 surrounding the bottom wall; wherein, at least one of the above-mentioned packaging material box baffles 1 is installed on each side wall 210. A fixing groove 211 matching the fixed block 110 is provided on each side wall 210.

[0084] In this embodiment, by pressing the T-shaped fixing block 110 into the fixing groove 211 on the side wall 210 of the packaging box, the packaging box stopper 1 is fixed in the packaging box 2 through the fixing block 110. As Figure 15 shown, 4 packaging box stoppers 1 are arranged in each rectangular packaging box 2. In practical applications, the number of packaging box stoppers 1 can be adjusted according to actual needs.

[0085] Meanwhile, as Figure 2 , Figures 15 to 17 shown, the bottom wall 221 of the packaging box can also be provided with a bottom groove 221 of the packaging box. When the packaging box stopper 1 is fixed to the packaging box 2, the bottom groove 221 of the packaging box enables the packaging box stopper 1 to be fixed more deeply in the packaging box 2. The support block bottom plate 123 of the packaging box stopper 1 is attached to the bottom groove 221 of the packaging box, making the installation of the packaging box stopper 1 more stable. In practical applications, the length, width, and depth of the bottom groove 221 of the packaging box can be adjusted according to production needs, as long as the packaging box stopper 1 can be fixed more deeply in the packaging box 2.

[0086] In this embodiment, during the process of turnover transportation or putting into the production line, the connection position between the first connection structure 121 and the second connection structure 143 is adjusted, and the second connection structure 143 near the second side 142 of the adjustment block is matched with the first connection structure 121, so that the blocking block 130 is parallel to the thickness direction of the display panel 3, enabling the packaging box stopper 1 to form a limiting and buffering effect on the display panel 3.

[0087] During the process of taking out the display panel 3 from the packaging box 2, the connection position between the first connection structure 121 and the second connection structure 143 is adjusted, and the second connection structure 143 near the first side 141 of the adjustment block is matched with the first connection structure 121, so that an inclined angle is formed between the blocking block 130 and the thickness direction of the display panel 3, ensuring that there is a gap between the packaging box stopper 1 and the display panel 3 during the process of taking out the display panel 3, thereby effectively reducing the problem of damage to the display panel 3 caused by interference between the packaging box stopper 1 and the display panel 3. Thus, the yield rate of manufacturing the display panel 3 is improved, the cost of manufacturing the display panel 3 is reduced, and the operating rate of the production equipment for the display panel 3 is further increased.

[0088] In this embodiment, buffer corners 230 can also be provided at the corners of the four side walls 210 of the packaging box, which are used to unload stress and play a buffering role, thereby enhancing the structural strength of the packaging box 2.
