[0037] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0038] like Figure 1-4 As shown, a box cover device for a vacuum setting box is used for a vacuum setting box 1, comprising:

[0039] Two box support ears 2, the box support ears 2 are fixedly installed on the vacuum shaping box 1, the box support ears 2 include a support plate and a side wall connected to the support plate, and the side wall is provided with an arc-shaped through groove;

[0040] Two box cover ears 3, the box cover ears 3 are hinged to the box body ears 2 through a hinge assembly;

[0041] The transparent cover plate 4 is fixedly mounted on the box cover support ear 3;

[0042] Handle 5, the handle 5 is installed on the transparent cover 4;

[0043] The rotating frame 6 is fixed outside the hinge assembly and rotates synchronously with the hinge assembly. The rotating frame 6 is provided with a limit connection groove;

[0044] A limit pin 7 is movably arranged on the rotating frame 6;

[0045] Among them, when the transparent cover plate 4 is rotated to a certain angle, the box cover support ear 3 is suitable for abutting against the support plate of the box body support ear 2 to form a first limit, and at the same time, the limit pin 7 is suitable for passing through the limit connecting groove and the arc-shaped through groove in sequence, and abutting against the inner side of the support plate of the box body support ear 2 to form a second limit.

[0046] In this embodiment, if Figure 1-3 As shown, when the transparent cover 4 is opened and continues to rotate, the box cover lug 3 connected to the transparent cover 4 will abut against the box body lug 2, thereby reaching the maximum opening angle, that is, the first limit. Subsequently, the limit pin 7 passes through the limit connection groove of the rotating frame 6 and the arc-shaped through groove on the side wall of the box body lug 2, and the side of the limit pin 7 abuts against the other side of the box cover lug 3, further forming a second limit, thereby ensuring that when the transparent cover 4 is opened, its position is stably restricted to prevent accidental movement. The number of box body lugs 2 and box cover lugs 3 can be reasonably set according to the size of the vacuum molding box 1. Usually, 2 to 4 box body lugs 2 are symmetrically arranged on both sides of the vacuum molding box 1, and each box lug 2 is connected to a box cover lug 3 to ensure that the transparent cover 4 is evenly stressed and moves smoothly when opening and closing.

[0047] Specifically, such as Figure 1 and Figure 3-4 As shown, the box cover device of the vacuum setting box also includes a sealing component, which includes:

[0048] A first sealing strip mounting frame 81 is annularly mounted on the periphery of the box cover of the vacuum setting box 1, and a first embedding groove is provided on the first sealing strip mounting frame 81;

[0049] A second sealing strip mounting frame 82 is annularly mounted on the periphery of the bottom surface of the transparent cover plate 4, and a second embedding groove is provided on the second sealing strip mounting frame 82;

[0050] A first sealing strip 811, which is embedded in the first sealing strip mounting bracket 81 through a first embedding groove;

[0051] A second sealing strip 821, which is embedded in the second sealing strip mounting bracket 82 through a second embedding groove;

[0052] When the transparent cover 4 is in the closed state, the first sealing strip 811 and the second sealing strip 821 are adapted to abut against each other to form a sealing structure.

[0053] In this embodiment, if Figure 1 and Figure 3-4 As shown, when the transparent cover 4 is in the open state, the first sealing strip 811 and the second sealing strip 821 are separated; when the transparent cover 4 is closed, the first sealing strip 811 and the second sealing strip 821 are attached to each other, forming a sealing structure between the two sealing strips. The sealing surface effectively prevents the circulation of air inside and outside the vacuum setting box 1, thereby ensuring the vacuum degree inside the vacuum setting box 1.

[0054] Specifically, such as Figure 4 As shown, the first sealing strip 811 and the second sealing strip 821 are magnetic sealing strips.

[0055] In this embodiment, if Figure 1 and Figure 3-4 As shown, the first sealing strip 811 and the second sealing strip 821 are designed as magnetic sealing strips, generating a magnetic attraction between the two. When the transparent cover 4 is closed, the magnetic force between the magnetic sealing strips can automatically and tightly attract the two sealing strips together, enhancing the sealing effect and effectively preventing gas leakage in the vacuum setting box 1.

[0056] Specifically, such as Figure 4 As shown, the inner side of the contact surface of the first sealing strip 811 is provided with a protrusion extending along its length direction;

[0057] A groove matching the raised portion is provided on the inner side of the contact surface of the second sealing strip 821 , and the shapes of the raised portion and the groove match.

[0058] Specifically, such as Figure 1 and Figure 3 As shown, the box cover device of the vacuum setting box also includes a clamping mechanism, which includes:

[0059] The card slot seat 91 is fixedly mounted on the front side wall of the vacuum molding box 1 and is provided with a card slot;

[0060] The card protrusion 92 is fixedly provided on the front edge of the transparent cover 4, and the card protrusion 92 is provided with a card protrusion corresponding to the card slot position on the card slot seat;

[0061] When the transparent cover 4 is in the closed state, the latching protrusion is adapted to engage with the latching slot.

[0062] In this embodiment, if Figure 1 and Figure 3 As shown, the arrangement of the snap-fit ​​mechanism provides a reliable mechanical locking function for the vacuum molding box 1. The slot holder 91 is securely mounted on the front side wall of the vacuum molding box 1 and is connected to the vacuum molding box 1 by screw fastening or welding. The snap-fit ​​block 92 is fixed to the front edge of the transparent cover 4 to ensure that the snap-fit ​​block and the slot are precisely aligned when the transparent cover 4 is closed. When the transparent cover 4 is pressed down and closed, the snap-fit ​​block 92's snap-fitting protrusion enters the slot of the slot holder 91 along a preset trajectory. As the transparent cover 4 is fully closed, the snap-fitting protrusion and the slot are snap-fitted. This snap-fitting not only prevents the transparent cover 4 from accidentally opening under vacuum, but also provides a stable pressing force for the sealing assembly, further improving the sealing effect.

[0063] Specifically, such as Figure 1 As shown, the card slot of the card slot seat 91 is provided with an entrance portion and a limiting portion, the opening width of the entrance portion is greater than the width of the card protrusion, and the limiting portion is connected to the entrance portion;

[0064] The entrance of the card slot is in a trumpet shape to guide the card protrusion into the limiting portion.

[0065] In this embodiment, if Figure 1 and Figure 3 As shown, the opening width of the entrance portion is larger than the width of the latch protrusion, facilitating initial insertion of the latch protrusion. The stopper portion is connected to the entrance portion, and its width is adapted to the width of the latch protrusion, enabling precise positioning and reliable locking. The entrance portion adopts a trumpet-shaped design, which can quickly guide the latch protrusion into the stopper portion during the downward pressing of the transparent cover plate 4, improving operational convenience.

[0066] Specifically, such as Figure 1 and Figure 3 As shown, the transparent cover plate 4 is made of tempered glass.

[0067] Specifically, such as Figure 1 As shown, the handle 5 is made of 304 stainless steel.

[0068] In this embodiment, if Figure 1 and Figure 3As shown, the transparent cover 4 is made of tempered glass, which is cheap and transparent enough to allow the operator to clearly observe the working state inside the box. The handle 5 is made of 304 stainless steel, which will not age or break over time compared to injection molded parts.

[0069] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
