Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, and in particular to a packaging bag opening sealing and reinforcement clip. Background Technology

[0002] A packaging bag is a bag-shaped container used for packaging, protecting, and transporting goods, typically made of materials such as plastic, paper, or cloth. It can be designed in different shapes, sizes, and thicknesses depending on the nature and purpose of the goods, serving to prevent moisture or dust. The opening of the packaging bag is usually sealed, primarily to prevent the contents from being contaminated by external factors such as moisture, dust, or bacteria, thus maintaining the quality and safety of the goods. To enhance the sealing effect and ensure that the bag opening does not easily crack or loosen during transportation and storage, a packaging bag opening sealing and reinforcing clip is required.

[0003] A packaging bag sealing and reinforcing clip is an auxiliary tool used to enhance the sealing performance of packaging bag openings. In existing technologies, the clamping block of the reinforcing clip is usually integrated with the clip to seal the packaging bag opening. This method cannot adapt the reinforcing clip to packaging bag openings of different shapes or sizes, thus affecting the use of the reinforcing clip. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a packaging bag opening sealing and reinforcement clip, which aims to improve the problem that the reinforcement clip cannot adapt to the openings of packaging bags of different shapes or sizes when in use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A packaging bag opening sealing and reinforcement clip includes a clip body one. An arc-shaped block is provided on the inner wall of the clip body one. A hollow block is fixedly connected to the inner wall of the clip body one. An L-shaped block is slidably connected inside the hollow block. A slide rail one is slidably connected to the inner wall of the L-shaped block. The lower surface of the slide rail one is fixedly connected to the inner wall of the hollow block. A spring one is fixedly connected to the front outer wall of the L-shaped block. The front outer wall of the spring one is fixedly connected to the inner wall of the hollow block. A transmission plate is rotatably connected to the upper outer wall of the L-shaped block. A slider is rotatably connected inside the transmission plate. A slide rail two is slidably connected to the inner wall of the slider. The lower surface of the slide rail two is fixedly connected to the inner wall of the hollow block. A slide rod is fixedly connected to the right outer wall of the slider. The right outer wall of the slide rod is slidably connected to the inner wall of the arc-shaped block. A rotating assembly is provided on the upper surface of the clip body one for rotating the clip body two.

[0007] Preferably, the rotating assembly includes a fixed base, the lower surface of which is fixedly connected to the upper surface of the clamping body one, and the outer wall of the fixed base is rotatably connected to the clamping body two, the lower surface of which is fixedly connected to a U-shaped block.

[0008] Preferably, the middle outer wall of the slide rod is slidably connected to the inside of the clamping body, and the left outer wall of the slide rod is slidably connected to the inside of the hollow block.

[0009] Preferably, a fixing rod is fixedly connected to the inner wall of the clamp body two, and a limit block is rotatably connected to the outer wall of the fixing rod.

[0010] Preferably, a limiting rod is slidably connected to the inner wall of the limiting block, and a fixing block is fixedly connected to the outer wall of the limiting rod.

[0011] Preferably, the inner wall of the fixing block is slidably connected to a fixing frame, and the left outer wall of the fixing frame is fixedly connected to the right outer wall of the clamp.

[0012] Preferably, a push rod is slidably connected inside the fixing frame, and the rear outer wall of the push rod is fixedly connected to the front outer wall of the fixing block.

[0013] Preferably, a second spring is fixedly connected to the rear outer wall of the fixing frame, and the rear outer wall of the second spring is fixedly connected to the front outer wall of the fixing block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pulling the L-shaped block to slide on the outer wall of the slide rail, the spring is squeezed. The transmission plate drives the slider to move to the left through the L-shaped block. The slider drives the slide rod to slide to the left and slides out of the inner wall of the arc-shaped block without restriction, achieving the effect of flexibly replacing the arc-shaped block. At the same time, it is convenient to maintain and clean the reinforcing clamp.

[0016] 2. In this utility model, by rotating the clamping body two, the push rod is pulled to drive the fixed block and the limiting rod to move forward, which compresses the spring two. Under the action of the fixed rod, the limiting block is rotated to a suitable position, the push rod is released, and under the action of the spring two, the limiting rod is driven to move backward, which limits the limiting block and achieves the effect of improving the stability of the packaging bag during transportation and storage.

[0025] Reference Figure 2 The middle outer wall of the slide rod 10 is slidably connected to the inside of the clamp 1, and the left outer wall of the slide rod 10 is slidably connected to the inside of the hollow block 3.

[0026] Specifically, the interior of the hollow block 3 and the interior of the clamp 1 both achieve the effect of offset restriction on the sliding of the slide bar 10.

[0027] Reference Figure 3 A fixing rod 14 is fixedly connected to the inner wall of clamp 12, and a limiting block 15 is rotatably connected to the outer wall of the fixing rod 14; a limiting rod 20 is slidably connected to the inner wall of the limiting block 15, and a fixing block 19 is fixedly connected to the outer wall of the limiting rod 20; a fixing frame 16 is slidably connected to the inner wall of the fixing block 19, and the left outer wall of the fixing frame 16 is fixedly connected to the right outer wall of clamp 1; a push rod 17 is slidably connected inside the fixing frame 16, and the rear outer wall of the push rod 17 is fixedly connected to the front outer wall of the fixing block 19; a spring 18 is fixedly connected to the rear outer wall of the fixing frame 16, and the rear outer wall of the spring 18 is fixedly connected to the front outer wall of the fixing block 19.

[0028] Specifically, the fixing rod 14 of clamp 12 provides support for the limiting block 15, clamp 1 provides fixation for the fixing frame 16, the fixing frame 16 provides support for the push rod 17 and the fixing block 19, the inside of the fixing frame 16 limits the offset of the push rod 17, the outer wall of the fixing frame 16 limits the offset of the sliding of the fixing block 19, the spring 18 limits the range of the sliding of the fixing block 19, a notch is provided on the right side of clamp 1 to prevent interference with the rotation of the limiting block 15, the push rod 17 is pulled to transmit power between the fixing block 19 and the limiting rod 20, and the sliding of the limiting rod 20 limits the limiting block 15 and releases it.

[0029] Working principle: When using this reinforcing clamp, place the opening of the packaging bag on the upper side of the arc-shaped block 2. Under the action of the fixing seat 11, the clamp body 12 rotates to the right, causing the inner wall of the U-shaped block 13 to squeeze the opening of the packaging bag downwards, thereby wrapping the arc-shaped block 2 and achieving the effect of sealing the opening of the packaging bag. At the same time, under the action of the fixing rod 14, the limiting block 15 rotates to the left, pulling the push rod 17 inside the fixing frame 16, causing the fixing block 19 and the limiting rod 20 to move forward, compressing the spring 18. When the limiting block 15 rotates to the appropriate position, the push rod 17 is released. Under the rebound of the spring 18, the fixing block 19 and the limiting rod 20 slide backwards, limiting the movement. Rod 20 slides into the inner wall of limiting block 15 for limiting, achieving the effect of sealing and fixing the bag opening. When not using the reinforcing clip, by pulling L-shaped block 4 to slide on the outer wall of slide rail 1 5, spring 1 6 is squeezed. L-shaped block 4 drives transmission plate 7 to move forward and rotate to the left, driving slider 8 to slide to the left on the outer wall of slide rail 2 9, so that sliding rod 10 slides to the left inside hollow block 3 and slides out of the inner wall of arc block 2 without limiting, achieving the effect of quickly disassembling arc block 2. When using this reinforcing clip, it not only achieves the flexible adjustment of the size or shape of arc block 2 according to the needs of different types or sizes of packaging bags, but also has the effect of preventing the bag opening from loosening or not sealing properly due to external force or vibration.
