Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, in particular to a plastic bag sealing clip. Background Art
[0002] Plastic bags are commonly used items in daily life. When the materials inside the plastic bag have not been completely used up, in order to avoid waste, it is necessary to temporarily seal the opening of the plastic bag for reuse next time. Existing sealing clips generally use a clamp structure to hold the opening of the plastic bag, making the inner walls of the plastic bag fit together to achieve the purpose of sealing the opening. However, when the existing sealing clip holds the plastic bag, most of them make the inner walls of the plastic bag contact each other in a line. When there is liquid in the plastic bag, it is easy to cause liquid leakage. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a plastic bag sealing clip.
[0004] The technical solution of the utility model is as follows: A plastic bag sealing clip includes a first clip block and a second clip block. One end of the first clip block is rotatably connected to one end of the second clip block, and the other ends are clamped. The first clip block is provided with an elastic roller group that is rotatably connected. The second clip block is provided with a fixed seat corresponding to the elastic roller group. The elastic roller group includes a pair of rollers made of elastic materials. The rollers are parallel to each other and their ends are rotatably connected to the first clip block. There is a roller gap between the rollers for cooperating with the fixed seat. The two sides of the fixed seat are provided with curved slopes for cooperating with the rollers.
[0005] Further, one end of the first clip block is provided with a rotating shaft, and one end of the second clip is provided with a positioning cylinder for cooperating with the rotating shaft.
[0006] Further, one end of the first clip block away from the rotating shaft is provided with a convex edge, and the top surface of the convex edge is provided with anti-slip lines.
[0007] Further, the first clip block is provided with an opening for the fixed seat to pass through.
[0008] Further, the two ends of the fixed seat are provided with limiting plates, and the height of the limiting plates is higher than that of the fixed seat.
[0009] Further, the edges of the first clip block and the second clip block are provided with chamfers that cooperate with each other.
[0010] Further, one end of the first clip block is provided with a clamping block, and the second clip block is provided with a clamping plate for cooperating with the clamping block. A plurality of teeth meshing with the clamping block are provided along the length direction of the clamping plate.
[0011] Further, the clamping plate is an arc-shaped plate that fits the arc-shaped movement track of the clamping block, and the teeth are evenly distributed along the length direction of the arc-shaped plate.
[0012] Compared with the prior art, the advantages of the present utility model are as follows: The cooperation between the first clamping block and the second clamping block is utilized to freely open or seal the opening of the plastic bag. When the fixed seat is embedded in the roll gap, due to the elastic deformation of the roller and its fitting with the curved slope, the part of the plastic bag clamped between the roller and the curved slope achieves the effect of contact fitting on the inner wall surface, improving the sealing effect of the sealing clip and preventing liquid from leaking out of the plastic bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope protected by the present utility model.
[0020] The following will describe the specific embodiments of the present utility model in conjunction with the drawings:
[0021] Such as Figures 1 to 4As shown in the figure, a plastic bag sealing clip includes a first clip block 1 and a second clip block 2. One end of the first clip block 1 is provided with a rotating shaft 11, and one end of the second clip is provided with a positioning cylinder 21 that cooperates with the rotating shaft 11. The first clip block 1 and the second clip block 2 are rotationally connected through the cooperation of the rotating shaft 11 and the positioning cylinder 21. The other end of the first clip block 1 is provided with a clamping block 14, and the second clip block 2 is provided with a clamping plate 23 that cooperates with the clamping block 14. The first clip block 1 and the second clip block 2 are clamped through the cooperation of the clamping block 14 and the clamping plate 23. The thicknesses of different plastic bags are different, and different requirements are needed for the clamping angle between the first clip block 1 and the second clip block 2. A plurality of teeth 231 meshing with the clamping block 14 are provided in the length direction of the clamping plate 23. By adjusting the clamping plate 23 to mesh with different teeth 231, the angle between the first clip block 1 and the second clip block 2 is adjusted to adapt to plastic bags of different thicknesses. The clamping plate 23 is an arc-shaped plate that fits the arc-shaped movement track of the clamping block 14, and the teeth 231 are evenly distributed along the length direction of the arc-shaped plate. The arc-shaped plate can make the meshing degree of the clamping block 14 with each tooth 231 the same, making the clamping effect between the clamping block 14 and the clamping plate 23 stable.
[0022] A convex edge 13 is provided at the end of the first clip block 1 away from the rotating shaft 11, and anti-slip lines are provided on the top surface of the convex edge 13. The convex edge 13 facilitates the manual operation of the sealing clip for clamping. A plurality of uniformly distributed reinforcing ribs 12 are provided in the length direction of both the first clip block 1 and the second clip block 2. During the clamping process of the first clip block 1 and the second clip block 2, a relatively large load is applied in the length direction. The reinforcing ribs 12 facilitate improving the anti-deformation ability of the first clip block 1 and the second clip block 2. Chamfers 3 that cooperate with each other are provided at the edges of the first clip block 1 and the second clip block 2. When the first clip block 1 and the second clip block 2 are attached to each other, a secondary clamping of the plastic bag is formed, and the mutually cooperating chamfers 3 can increase the clamping area of the plastic bag, further improving the sealing effect of the sealing clip on the plastic bag.
[0023] The first clamping block 1 is provided with an elastic roller group 15 connected in a rotating manner, and the second clamping block 2 is provided with a fixed seat 22 corresponding to the elastic roller group 15. The elastic roller group 15 includes a pair of rollers 151 made of elastic material. The rollers 151 are parallel to each other and their ends are rotatably connected to the first clamping block 1. A roller gap for cooperating with the fixed seat 22 is provided between the rollers 151. The top of the fixed seat 22 is narrow and the bottom is wide. The top of the fixed seat 22 enters the roller gap. The rotating rollers 151 facilitate spreading the plastic bag along the two sides of the fixed seat 22 and matching the curved slopes 222 of the rollers 151. At the same time, the rollers 151 apply elastic force to the plastic bag due to elastic deformation, making the plastic bag closely adhere to the curved slopes 222. Thus, surface-contact fitting of the inner wall of the plastic bag is achieved, improving the sealing effect of the sealing clip on the plastic bag. Limiting plates 221 are provided at both ends of the fixed seat 22, and the height of the limiting plates 221 is higher than that of the fixed seat 22. The clamping part at the opening 16 of the plastic bag is restricted between the limiting plates 221 through the limiting plates 221, preventing insufficient clamping of the opening 16 of the plastic bag. The first clamping block 1 is provided with an opening 16 for the fixed seat 22 to pass through. Both the fixed seat 22 and the limiting plates 221 can pass through the opening 16, thereby increasing the clamping area of the plastic bag and optimizing the clamping tightness.
[0024] The working principle of the specific embodiment of the present utility model is as follows: Place the clamping part of the plastic bag between the limiting plates 221 of the fixed seat 22, and press the convex edge 13 to make the angle between the first clamping block 1 and the second clamping block 2 smaller. When the top of the fixed seat 22 presses against the plastic bag and passes through the roller gap formed by the elastic roller group 15, the plastic bag spreads along the curved slopes 222 on both sides of the fixed seat 22, and the plastic bag closely adheres to the curved slopes 222 under the elastic force of the rollers 151, achieving surface-contact fitting of the inner wall of the plastic bag.
