DETAILED DESCRIPTION

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] The present application will be further described in detail below in combination with specific embodiments, which cannot be understood as limiting the scope of the present application.

[0029] The present application relates to a loading plate 1 for a packaging container 3, which is used to hold pre-packaged appliances 2.

[0030] As shown in Figures 1-3 , the body of the packaging container 3 has a rectangular cavity structure 9 for accommodating the loading plate 1 and the pre-packaged appliances 2 loaded on the loading plate 1. The loading plate 1 comprises a planar support portion 4, and a plurality of accommodating portions 5 are distributed in an array on the planar support portion 4. The accommodating portions 5 have accommodating cavities 6 for accommodating the pre-packaged appliances 2, and the opening outer extension of the accommodating portions 5 is used to support the pre-packaged appliances 2.

[0031] The accommodating cavities 6 extend along one side of the planar support portion 4 to form a tubular structure with both ends open. The planar support portion 4 and the accommodating cavities 6 are formed as an integrated structure by injection molding process. The tubular structure has a top and a bottom, wherein the end close to the planar support portion 4 and adjacent to the planar support portion 4 is the bottom, and the end opposite to the bottom and away from the planar support portion 4 is the top.

[0032] like Figure 4 As shown, in a preferred embodiment, retaining structures 7 are equidistantly distributed on the same circumference of the inner wall of the receiving cavity 6. The retaining structures 7 can position the pre-packaged device 2 during placement into the receiving cavity 6, ensuring high coaxiality between the axis of the pre-packaged device 2 and the axis of the receiving cavity 6. Preferably, during the fabrication of the mounting plate 1, the retaining structures 7, the receiving portion 5, and the planar support portion 4 are integrally molded by injection molding.

[0033] The retaining structure 7 provides full support for the pre-packaged device 2 through a clearance fit with it. Specifically, the retaining structure 7 includes a retaining surface 8, which further comprises three parts: a first retaining surface 8-1, a second retaining surface 8-2, and a third retaining surface 8-3. The width of the second retaining surface 8-2 near the top of the receiving cavity 6 is smaller than the width of the second retaining surface 8-2 near the bottom of the receiving cavity 6, and the width of the second retaining surface 8-2 gradually increases from the top to the bottom.

[0034] In one embodiment, the second retaining surface 8-2 is a plane.

[0035] In another embodiment, the second retaining surface 8-2 is an arc surface.

[0036] The first retaining surface 8-1 and the third retaining surface 8-3 are inclined surfaces that intersect the second retaining surface 8-2. That is, the first retaining surface 8-1 is not parallel to the axis of the receiving cavity 6, and the third retaining surface 8-3 is not parallel to the axis of the receiving cavity 6. Both the first retaining surface 8-1 and the third retaining surface 8-3 form an acute angle with the inner wall of the receiving portion 5. The first retaining surface 8-1 and the third retaining surface 8-3 extend from the second retaining surface 8-2 toward the top and bottom of the receiving cavity 6, respectively. According to another embodiment, the first retaining surface 8-1 and the third retaining surface 8-3 are arc surfaces that intersect the second retaining surface 8-2. The first retaining surface 8-1 is not parallel to the axis of the receiving cavity 6, and the third retaining surface 8-3 is not parallel to the axis of the receiving cavity 6. The first retaining surface 8-1 and the third retaining surface 8-3 extend from the second retaining surface 8-2 toward the top and bottom of the receiving cavity 6, respectively. The first retaining surface 8-1 and the third retaining surface 8-3 intersect with the inner wall of the receiving cavity 6.

[0037] In other embodiments, either the first retaining surface 8-1 or the third retaining surface 8-3 may be the aforementioned inclined surface, and the other may be the aforementioned arc surface. Specifically, in one embodiment, the first retaining surface 8-1 is an inclined surface that intersects the second retaining surface 8-2 and extends from the second retaining surface 8-2 toward the top of the receiving cavity 6, and the third retaining surface 8-3 is an arc surface that intersects the second retaining surface 8-2 and extends from the second retaining surface 8-2 toward the bottom of the receiving cavity 6; in another embodiment, the third retaining surface 8-3 is an inclined surface that intersects the second retaining surface 8-2 and extends from the second retaining surface 8-2 toward the bottom of the receiving cavity 6, and the first retaining surface 8-1 is an arc surface that intersects the second retaining surface 8-2 and extends from the second retaining surface 8-2 toward the top of the receiving cavity 6.

[0038] The supporting effect of the aforementioned retaining structure 7 on the pre-packaged device 2 mainly comes from two aspects: first, the limiting effect of the second retaining surface 8-2 on the pre-packaged device 2, preventing the pre-packaged device 2 from being biased within the cavity of the receiving cavity 6; second, the positioning effect of the first retaining surface 8-1 and the third retaining surface 8-3 on the pre-packaged device 2, enabling the pre-packaged device 2 to be stored with essentially no shaking and to move smoothly and without shaking in the axial direction of the receiving cavity 6 when it is inserted into or removed from the receiving cavity 6.

[0039] Furthermore, the retaining structure 7 and the pre-packaged device 2 are fitted with a clearance fit. This design allows for a certain gap between the inner walls of the pre-packaged device 2 and the retaining structure 7, making the entire assembly and disassembly process faster. Most importantly, the reserved gap can compensate for process errors caused by manufacturing or thermal expansion. However, in order to minimize the swaying of the pre-packaged device 2 within the receiving cavity 6, the clearance distance on one side of the pre-packaged device 2 and the retaining structure 7 should be ≤0.5mm, and the total clearance distance between the pre-packaged device 2 and both sides of the retaining structure 7 should be ≤1mm.

[0040] As mentioned earlier, the planar support part 4 and the receiving part 5 are formed into an integrated structure through injection molding. To improve the success rate of demolding, the diameter of the inner wall of the receiving cavity 6 gradually increases from the top to the bottom of the receiving cavity 6, that is, a structure with a narrower top opening and a wider bottom opening is formed in the receiving cavity 6. This structure with a narrow top and a wide bottom enables the mounting plate 1 to be demolded quickly without sticking.

[0041] like Figure 4 As shown, according to a preferred embodiment, the width of the second retaining surface 8-2 near the top end is smaller than the width near the bottom end. More preferably, the width A of the second retaining surface 8-2 near the top of the receiving cavity 6 is 0.8±0.15mm, and the width B of the second retaining surface 8-2 near the bottom of the receiving cavity 6 is 1.5±0.15mm.

[0042] In the axial direction, the second retaining surface 8-2 is closer to the top end to the top than to the bottom end to the bottom, that is, the axial projection length of the first retaining surface 8-1 is greater than the axial projection length of the third retaining surface 8-3.

[0043] The second retaining surface 8-2 can constitute the minimum inscribed circle in the accommodating cavity 6. As a preferred embodiment, the diameter D of the inscribed circle of the second retaining surface 8-2 ranges from 7.05±0.3mm to 24.60±0.3mm. Specific embodiments are as follows:

[0044]

[0045] According to one of the embodiments, the number of retaining structures 7 on each tubular structure inner wall is greater than or equal to 3, and preferably the number of retaining structures 7 is 6. Each retaining structure 7 is arranged in the axial direction of the accommodating cavity 6 and is uniformly distributed in the circumferential direction of the accommodating cavity 6. It can be seen that a larger number of retaining structures 7 can improve the stability of the pre-packaging device 2.

[0046] According to a preferred embodiment, the long edge of the accommodating plate 1 is symmetrically provided with a gap structure for easy grabbing.

[0047] In actual production, taking 6 retaining structures 7 as an example, when the maximum outer diameter of the pre-packaging device 2 is 16.7mm, the diameter D of the inscribed circle of the second retaining surface 8-2 is 17.00±0.3mm. When packaging the pre-packaging device 2, the pre-packaging device 2 is vertically inserted into the accommodating cavity 6 along the axial direction of the accommodating portion 5. Under the action of the retaining structure 7, the pre-packaging device 2 can always maintain high coaxiality with the axis of the accommodating cavity 6, and the interference of the pre-packaging device 2 when inserted or extracted from the accommodating cavity 6 is maximally eliminated.

[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
