Technical Field

[0001] The utility model belongs to the technical field related to manual air pumps, and particularly relates to a manual air pump. Background Technique

[0002] A manual air pump is a small and portable device used to evacuate air from compression bags. It mainly consists of a handle and a piston. By manually operating the piston, users can effectively extract the air inside the bag, thereby creating a vacuum state inside the bag. This can not only greatly save storage space but also protect the items inside the bag from moisture, dust, or pests. The manual air pump is easy to operate and does not require a power source, making it suitable for the vacuum storage of various types of clothes and quilts in the family.

[0003] When injecting glue into the traditional glue injection holes on the bottom cover plate, the glue will splash out and overflow onto the surface of the product, affecting the appearance. The overflowing glue will stick to the hands of the assembly workers, affecting the health of the workers. Therefore, the market needs a new device to solve the problems currently faced. Content of the Utility Model

[0004] The purpose of the utility model is to provide a manual air pump to solve the problems that when injecting glue into the traditional glue injection holes on the bottom cover plate, the glue will splash out and overflow onto the surface of the product, affecting the appearance. The overflowing glue will stick to the hands of the assembly workers, affecting the health of the workers. Therefore, the market needs a new device to solve the problems currently faced.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a manual air pump, including a main body cylinder, a pull rod is installed inside the main body cylinder, a grip is installed at the upper end of the pull rod, a silica gel ring is installed at the lower end of the pull rod, a convex mechanism is arranged at the lower position on the outer wall of the main body cylinder, the main body cylinder is clamped with a bottom cover plate at the lower end through the convex mechanism, the bottom cover plate is installed with the main body cylinder through a buckle on the inner wall, a threaded structure is arranged at the inner wall position of the bottom cover plate, and glue injection holes are arranged at the left and right ends at the lower end of the bottom cover plate.

[0006] Preferably, an anti-slip groove is arranged at the upper end position of the grip.

[0007] Preferably, the grip controls the movement of the pull rod through a manual operation method.

[0008] Preferably, the pull rod drives the silica gel ring to move, and the silica gel ring moves along the inner wall of the main body cylinder.

[0009] Preferably, when the bottom cover plate is installed with the main body cylinder, the buckle and the convex mechanism are clamped.

[0010] Preferably, glue can be injected into the bottom cover plate through the glue injection holes at the lower end position.

[0011] Preferably, the structure of the handle is set as an arc structure.

[0012] Preferably, the bottom cover plate is screwed tightly with the external thread of the air outlet of the compression bag through the thread structure on the inner wall.

[0013] Compared with the prior art, the present utility model provides a manual air pump, which has the following beneficial effects:

[0014] 1. There are two glue injection holes in the bottom cover plate of the device. After the overall product, especially the main cylinder and the bottom cover plate, are generally assembled, glue is injected through these holes to firmly connect the main cylinder and the bottom cover plate, preventing the risk of separation of the product due to strong pulling during use. At the same time, through the glue injection holes in the bottom cover plate, glue connection can be realized after the overall product assembly is completed, avoiding the situation in the same type of products where glue is adhered to the lower edge of the main cylinder or the inner side of the bottom cover plate and then assembled.

[0015] 2. The two sides of the top end of the handle of the device are provided with anti-slip grooves, which can make the use process more comfortable and reliable, and at the same time reduce the weight of the plastic parts without affecting the structural strength.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The utility model provides a manual air pump as Figures 1-4 shown, which includes a main body cylinder 1. A pull rod 5 is installed at the inner position of the main body cylinder 1. A grip 3 is installed at the upper end of the pull rod 5. A silica gel ring 6 is installed at the lower end of the pull rod 5. A convex mechanism 9 is arranged at the lower position of the outer wall of the main body cylinder 1. The main body cylinder 1 is clamped with a bottom cover plate 2 at the lower end through the convex mechanism 9. The bottom cover plate 2 is installed with the main body cylinder 1 through a buckle 8 at the inner wall position. A threaded structure 7 is arranged at the inner wall position of the bottom cover plate 2. Glue injection holes 4 are arranged at the left and right ends of the lower end of the bottom cover plate 2.

[0023] Screw the external thread of the air outlet of the compression bag onto the threaded structure 7 of the bottom cover plate 2. The operator holds the grip 3 tightly and starts to move the silica gel ring 6 up and down inside the main body cylinder 1. At this time, the air pump will suck out the air in the bag, and the bag will gradually shrink and become tight until the bag looks completely compressed and there is no air left.

[0024] As Figure 2 and Figure 3 shown, an anti-slip groove 10 is arranged at the upper end of the grip 3. The grip 3 controls the movement of the pull rod 5 through manual operation. The pull rod 5 drives the silica gel ring 6 to move. The silica gel ring 6 fits and moves along the inner wall of the main body cylinder 1. The installation of the bottom cover plate 2 and the main body cylinder 1 clamps the buckle 8 and the convex mechanism 9. Glue can be injected through the glue injection holes 4 at the lower end of the bottom cover plate 2. The structure of the grip 3 is set as an arc structure. The bottom cover plate 2 is screwed tightly with the external thread of the air outlet of the compression bag through the threaded structure 7 at the inner wall.

[0025] There are two glue injection holes 4 on the bottom cover plate 2. After the whole product, especially the main body cylinder 1 and the bottom cover plate 2, are generally assembled, glue is injected through these holes to firmly connect the main body cylinder 1 and the bottom cover plate 2, preventing the risk of separation of the product due to strong pulling during use. At the same time, at the glue injection holes 4 of the bottom cover plate 2, glue connection can be realized after the whole product is assembled, avoiding the situation of the same type of product sticking glue on the lower edge of the main body cylinder 1 or the inner side of the bottom cover plate 2 and then assembling them together.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
