Description

Technical Field

[0001] The utility model relates to the field of air pumps, in particular to a foldable air pump. Background Art

[0002] Common existing manual pressing and inflating devices include air pumps or other items. The principle is that the device is composed of a base, a cylinder body, a piston inner rod, a handle and other parts that can be pressed to generate high-pressure gas. Because the base needs to be stable and cannot move when manually pressing and inflating, the base is often provided with pressure plates or pressure rods on both sides that can be stepped on by the feet to stabilize the base and prevent it from moving. The handle part needs to be held tightly with both hands when pressing and inflating, and the handle is in a horizontal state at this time. Only in this way can the force required for inflating be completed.

[0003] The horizontal position of the handle makes the air pump inconvenient to carry. Generally, a foldable structure is used to fold the handle to reduce the space it occupies. Existing air pumps require an external positioning mechanism to position the handle in the folded and unfolded states during the folding process. This not only makes the overall structure more complex and the assembly process more troublesome, but also makes the folding and unfolding operations more cumbersome, affecting the user experience. Therefore, it is necessary to further improve the existing air pump structure. Utility Model Content

[0026] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present utility model, which includes a base component 1, a barrel component 2 and a handle component 4.

[0027] The base assembly 1 includes a base shell 1-1 and an elastic pressure rod 1-4; the base shell 1-1 is provided with movable grooves at equal angles on all sides, and the bottom of each movable groove is inwardly recessed with a first positioning groove 1-2 and a second positioning groove 1-3; the first positioning groove 1-2 and the second positioning groove 1-3 are arranged at a certain angle between their extension directions, and the first positioning groove 1-2 and the second positioning groove 1-3 are transitionally connected by a sliding surface; the elastic pressure rod 1-4 is set in two, and each elastic pressure rod 1-4 has positioning rods at both ends that are bent to cooperate with the first positioning groove 1-2 and the second positioning groove 1-3. After the outer end of the positioning rod is bent, it is hinged between the side wall of the movable groove, and each elastic pressure rod 1-4 is flipped and positioned between the base shell 1-1 through the cooperation of the positioning rod with the first positioning groove 1-2 and the second positioning groove 1-3 respectively, so that the elastic pressure rod 1-4 is positioned after rotation through the cooperation of the elastic pressure rod 1-4 itself with the first positioning groove 1-2 and the second positioning groove 1-3. No external positioning mechanism is required, and the overall structure is simpler.

[0028] In the present embodiment, the first positioning groove 1-2 and the second positioning groove 1-3 extend in a right angle with each other, and the first positioning groove 1-2 is extended up and down. The elastic pressure rod 1-4 can be turned up and down 90 degrees in the movable groove by the cooperation of the positioning rod with the first positioning groove 1-2 and the second positioning groove 1-3 respectively. At this time, when the elastic pressure rod 1-4 is folded and retracted, it is just in the vertical direction and fits against the side wall of the barrel assembly 2, so that the space occupied by it is minimized. In other embodiments, the angle between the first positioning groove 1-2 and the second positioning groove 1-3 can also be other angles, as long as it can meet the requirements of folding and retracting the elastic pressure rod 1-4. The first positioning groove 1-2 and the second positioning groove 1-3 are both semicircular, and correspondingly, the cross section of the positioning rod is circular, so that it is convenient for the positioning rod to leave the first positioning groove 1-2 and the second positioning groove 1-3, and the folding process is more convenient. The first positioning groove 1-2 and the second positioning groove 1-3 are respectively located on the inner side of the side wall of the movable groove. When the positioning rod is positioned in the first positioning groove 1-2 and the second positioning groove 1-3, they respectively abut against the corresponding side wall, thereby limiting the position of the elastic pressure rod 1-4 through the corresponding side wall, making the overall structure more stable. The elastic pressure rod 1-4 is made of elastic metal.

[0029] The barrel assembly 2 is arranged on the base assembly 1; in this embodiment, an inner rod 3 extending up and down is provided at the upper end of the barrel assembly 2.

[0030] The grip assembly 4 is arranged at the upper end of the barrel assembly 2, and the grip assembly 4 includes a grip shell 4-1, a grip 4-5 and an elastic member 4-6; the grip shell 4-1 is arranged at the upper end of the barrel assembly 2, and the grip shell 4-1 is symmetrically provided with two mounting grooves with two outer ends and a lower end opening on the left and right sides; the grip 4-5 is arranged in two, and the inner end of each grip 4-5 can be flipped up and down and slid back and forth in the corresponding mounting groove; the elastic member 4-6 is at least two, and the at least two elastic members 4-6 are respectively connected to the grip shell 4-1 and the corresponding grip 4-5, and drive the corresponding inner end of the grip 4-5 to rest against the side wall of the mounting groove. In this embodiment, the handle assembly 4 is mounted on the upper end of the inner rod 3. A fixed shaft 4-7 is integrally extended outward from the inner sidewall of the mounting slot. A sliding groove 4-9 is formed at the inner end of the handle 4-5, which cooperates with the fixed shaft 4-7. The sliding groove 4-9 extends in the same direction as the handle 4-5. The handle 4-5 continues to slide and rotate with the handle housing 4-1 through the cooperation of the sliding groove 4-9 and the fixed shaft 4-7. A positioning pin 4-8 is provided at the outer end of the handle 4-5. Two elastic members 4-6 are provided, and the two ends of each elastic member 4-6 are respectively connected to the corresponding fixed shaft 4-7 and positioning pin 4-8. The mounting slot includes a first sidewall 4-4 facing downward and a second sidewall 4-2 facing outward from the handle housing 4-1. A curved ear 4-3 with an arc-shaped sidewall protrudes outward between the first sidewall 4-4 and the second sidewall 4-2. The sidewall of the curved ear 4-3 not only limits the inner end of the handle 4-5 but also facilitates the rotation of the handle 4-5. The elastic member 4-6 is a tension spring. Similarly, the elastic member 4-6 can also be other components that can press the handle 4-5 toward the sidewall of the mounting slot.

[0031] The usage process of this embodiment is described in detail as follows:

[0032] When the elastic pressure rods 1-4 on the base assembly 1 are opened, it is only necessary to push the two elastic pressure rods 1-4 outward. At this time, the two ends of the two elastic pressure rods 1-4 are stretched outward and leave the first positioning groove 1-2, and flip outward under the action of external force until the two ends of the elastic pressure rods 1-4 move to the second positioning groove 1-3. At this time, the two ends of the elastic pressure rods 1-4 are positioned in the second positioning groove 1-3 under the action of their own elasticity; when the elastic pressure rods 1-4 need to be folded up, it is only necessary to push the two elastic pressure rods 1-4 upward.

[0033] When opening the handle assembly 4, it is only necessary to pull the two handles 4-5 downward first. At this time, the inner ends of the handles 4-5 leave the first side wall 4-4, and the elastic member 4-6 is stretched. Then, the two handles 4-5 are flipped upward along the side walls of the arc-shaped ears 4-3, and then the two handles 4-5 are released. At this time, the inner ends of the handles 4-5 move inward under the action of the elastic member 4-6 and rest on the second side wall 4-2. When the handle 4-5 needs to be folded up, it is only necessary to pull the handle 4-5 outward first, turn the handle 4-5 downward, and then release the handle 4-5 so that it can be reset under the action of the elastic member 4-6.

[0034] The design focus of the present invention is that the inner end of the handle can be flipped up and down and slid back and forth in the corresponding installation groove, and is respectively connected to the handle shell and the corresponding handle with at least two elastic parts, and drives the corresponding inner end of the handle to rest against the side wall of the installation groove; the handle assembly is positioned after folding by the internal elastic part, and there is no need to operate the external positioning mechanism. Not only is the structure simpler, but the assembly and use process is also more convenient, and the user experience is also better.

[0035] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
