Description

Technical Field

[0001] This utility model relates to the field of bag manufacturing, and more specifically, to a foldable internal support positioning fixture. Background Technology

[0002] In the field of bag manufacturing, after the bag body is supported, it will collapse due to the softness of the material and will not form a three-dimensional shape. When processing other processes on the outer surface of the bag, it is necessary to manually support the bag body from the inside to complete the outer surface process. This process of supporting the bag from the inside while processing the outer surface is difficult and results in low processing efficiency. For bags with small openings and large cavities, if a single support block is used to support the inside of the bag, it is difficult to insert the support block into the bag because of the small opening. If it is forced in, it is also difficult to remove, resulting in poor practicality. Therefore, there is an urgent need for a foldable internal support positioning fixture. Utility Model Content

[0003] This utility model provides a foldable internal support positioning fixture, which aims to improve the existing problems of poor practicality caused by the need for manual internal support and the difficulty in inserting a whole support block into the bag body when processing the outer surface of a trapezoidal bag.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a foldable internal support positioning fixture, comprising a first support rod, a second support rod, and a fixing rod arranged symmetrically. The first support rod and the second support rod are both L-shaped. The horizontal ends of the first support rod and the horizontal ends of the second support rod are rotatably connected. The vertical end of the first support rod has a slot, and a protrusion is provided inside the slot. The vertical end of the second support rod has a protrusion. The fixing rod has a strip groove in the middle, a first slot is provided at one end of the fixing rod, and a limiting block is provided at the other end.

[0005] Furthermore, the vertical portions of the first support rod and the second support rod are divided into two sections, which are connected by a hinge, and the protrusion has a second slot.

[0006] Furthermore, the first support rod and the second support rod include a support plate and an intermediate stiffening plate.

[0007] Furthermore, the rib plate at the horizontal end of the first support rod has a U-shaped groove, and the horizontal end of the second support rod protrudes from the mounting block, with through holes in the mounting block and the U-shaped groove.

[0008] Furthermore, the first support rod, the second support rod, and the fixing rod are all made of acrylic sheet.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model discloses a foldable internal support positioning fixture with a simple and ingenious design. It includes symmetrically arranged first support rods, second support rods, and fixing rods. Both the first and second support rods are L-shaped, and their horizontal ends are rotatably connected. The vertical end of the first support rod has a slot with a protrusion inside. The vertical end of the second support rod has a protrusion. The fixing rod has a slot in the middle, a first groove at one end, and a limiting block at the other end. In use, the first and second support rods are rotated around their hinge point, bringing them closer together for easy insertion into a bag. After insertion, the first and second support rods unfold to both sides around their junction point. One end of the fixing rod is secured in the slot via the first groove, while the limiting block at the other end abuts against the protrusion, thus supporting the first and second support rods in an open, supportive state inside the bag. The foldable design facilitates insertion and removal from the bag, improving practicality. Attached Figure Description

[0026] Example

[0027] Reference Figure 1-3 As shown, this utility model discloses a foldable internal support positioning fixture, including a symmetrically arranged first support rod 10, a second support rod 20, and a fixing rod 30. Both the first support rod 10 and the second support rod 20 are L-shaped, and their horizontal ends are rotatably connected. Specifically, the first support rod 10 and the second support rod 20 include a support plate and a central stiffener. The central stiffener strengthens the overall rigidity, and the support plate supports the interior of the bag, increasing the contact area and improving the support effect. The stiffener at the horizontal end of the first support rod 10 has a U-shaped groove, and the horizontal end of the second support rod 20 protrudes from a mounting block. The mounting block and the U-shaped groove have through holes. Bolts pass through the through holes in the mounting block via the U-shaped groove, allowing the first support rod 10 and the second support rod 20 to rotate around the bolts, enabling the opening and closing of the first support rod 10 and the second support rod 20. When closed, they are easily placed inside the bag; when open, they can be used to support the internal structure of the bag.

[0028] Reference Figure 4-6 As shown, the vertical end of the first support rod 10 has a latch 101, the vertical end of the second support rod 20 has a protrusion 201, and the fixing rod 30 has a slot in the middle. One end of the fixing rod 30 has a first latch 301, and the other end has a limiting block 302. Specifically, after the first support rod 10 and the second support rod 20 are placed into the bag, the two support rods unfold on both sides. The first latch 301 of the fixing rod 30 locks into the protrusion 1011 of the latch 101 at the vertical end of the first support rod 10, and the limiting block 302 at the other end of the fixing rod 30 abuts against the protrusion 201. The fixing rod 30 opens the first support rod 10 and the second support rod 20, supporting the internal structure of the bag. Removing the fixing rod 30 allows the first support rod 10 and the second support rod 20 to rotate around the hinge point and move closer to each other, making it easy to take out of the bag.

[0029] Reference Figure 7As shown, in another embodiment, the vertical portions of the first support rod 10 and the second support rod 20 are two segments connected by a hinge. The protruding portion 201 has a second slot 2011, and the slot 101 contains a protrusion 1011. As is well known, bags come in different sizes. When the bag is small, the first support rod 10 and the second support rod 20 are bent around the hinge point. After being placed inside the bag, the upper protruding portion 201 of the second support rod 20 inserts into the slot 101 of the first support rod 10, and the second slot 2011 engages with the protrusion 1011 within the slot 101, thus opening and fixing the first support rod 10 and the second support rod 20. The fixing rod 30 is not needed. The bending of the vertical portions of the first support rod 10 and the second support rod 20 reduces the overall size of the fixture, and the use of the two-end structure for clamping and fixing further improves practicality.

[0030] Furthermore, in this embodiment, the first support rod 10, the second support rod 20, and the fixing rod 30 are all made of acrylic sheet, which is easy to process and has low cost.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
