Technical Field

[0001] This utility model belongs to the field of air pump technology, and specifically relates to an air belt storage structure for an air pump. Background Technology

[0002] An air pump, also called a tire inflator, is used to pump air. When the air pump draws air, the valve of the inflator is opened by atmospheric pressure, and the air enters the cylinder. When inflating the tire, the valve is closed by the air pressure inside the cylinder, and the air enters the tire.

[0003] Traditional air pumps typically have freely coiled and twisted inflation hoses, which can easily damage the hoses and make storage and transportation inconvenient. Some air pumps on the market now have storage slots on their casings to hold the inflation hoses. For example, Chinese Utility Model Patent Application No. CN 202120889850.7 discloses a portable inflation device, which includes an air pump body, a casing, and an air source component housed within the casing. A switch component is fixedly mounted on the front end of the casing, and an air hose storage slot is located on the rear end.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, the inflation tube can move into the storage cavity along with the mounting frame, and the end cap can cover the end of the storage cavity. During the storage and transportation of the air pump, the inflation tube is not easily touched by gaseous objects, which can prevent the inflation tube from freely extending or being damaged by other items during storage and transportation. This facilitates the storage and transportation of the air pump and helps extend its service life. During the use of the air pump, the elastic element can drive the mounting frame and inflation tube to pass out of the storage cavity, making it convenient for users to use the air pump quickly. This structure can also prevent the mounting frame from accidentally retracting into the storage cavity during the use of the air pump, and prevent the mounting frame and the outer shell from clamping the inflation tube and causing damage. The locking element and the connecting part can prevent the mounting frame and inflation tube from accidentally passing out of the storage cavity during storage and transportation, which facilitates the storage and transportation of the air pump.

[0020] 2. The driving surface in this utility model facilitates the automatic engagement of the locking component and the connecting part, allowing the user to quickly retract the inflation tube and mounting bracket into the storage cavity, thus facilitating the storage of the air pump. The press-lock structure not only makes it easy for the user to quickly retract the inflation tube and mounting bracket into the storage cavity, but also makes it easy for the user to control the inflation tube and mounting bracket to pass out of the storage cavity, making it convenient for the user.

[0021] 3. The movable connecting rod and connecting pipe in this utility model can prevent deformation of the inflation pipe during the relative movement of the mounting frame and the outer shell, thus avoiding damage to the inflation pipe or the connection between the inflation pipe and the air pump, and helping to extend the service life of the air pump. The design of the connecting rod and the hinge hole allows the inflation pipe and the mounting frame to rotate relative to each other, making it convenient for the user to flexibly control the connection between the inflation pipe and the inflated item. The design of the hinge protrusion and hinge groove facilitates the stable rotation of the inflation pipe and the mounting frame, preventing the hinge part from tilting towards the hinge hole side during the use of the air pump, which could lead to damage to the hinge part and the hinge hole, and further extending the service life of the air pump.

[0022] 4. The mounting groove in this utility model facilitates the winding and storage of the inflation tube, avoids knotting, and makes it convenient for the storage and extension of the inflation tube, making it convenient for users to use. The anti-tightening protrusion reduces the friction between the inflation tube and the mounting groove, making it easier for users to control the storage and extension of the inflation tube, and can prevent the inflation tube and the mounting groove from being severely worn after long-term use, which would affect the stable installation of the inflation tube.

[0023] 5. The guide rod and guide groove in this utility model facilitate the stable sliding of the mounting frame and the outer shell, while the limiting groove and limiting protrusion can limit the range of motion of the mounting frame and the outer shell, allowing the mounting frame and the outer shell to swing freely during the use of the air pump, which is convenient for the user; since the elastic element is set in the guide groove, the elastic element can deform stably during the relative movement of the mounting frame and the outer shell, avoiding the bending deformation of the elastic element from affecting the reset of the mounting frame.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0036] See Figures 1 to 10 As shown, an air pump 2 air-belt storage structure includes a housing 1 and an air pump 2. The housing 1 is equipped with a controller 6 for controlling the air pump 2. An air pump 2 is connected to an air tube 4. The housing 1 has a storage cavity 11, and a mounting frame 3 is movably disposed in the storage cavity 11. An end cap 36 is provided on the mounting frame 3. The air tube 4 is wound or stored on the mounting frame 3. The air tube 4 can move into the storage cavity 11 together with the mounting frame 3, so that the air tube 4 is stored in the storage cavity 11 and the end cap 36 covers the end of the storage cavity 11. This structure makes it difficult for the air tube 4 to be touched by gaseous objects during the storage and transportation of the air pump 2, which can prevent the air tube 4 from freely extending or being damaged by other objects during storage and transportation, facilitates the storage and transportation of the air pump 2, and helps to extend the service life of the air pump 2.

[0037] The outer shell 1 is provided with an elastic element 5, which can drive the mounting frame 3 to move and allow the inflation tube 4 to pass through the storage cavity 11. The outer shell 1 and the mounting frame 3 are respectively provided with a locking element 7 and a connecting part 35. The locking element 7 and the connecting part 35 cooperate to control the relative fixation of the outer shell 1 and the mounting frame 3 and to store the inflation tube 4 in the storage cavity 11. During the use of the air pump 2, the elastic element 5 can drive the mounting frame 3 and the inflation tube 4 to pass through the storage cavity 11, which is convenient for users to use the air pump 2 quickly. This structure can prevent the mounting frame 3 from accidentally retracting into the storage cavity 11 during the use of the air pump 2, and prevent the mounting frame 3 and the outer shell 1 from clamping the inflation tube 4 and causing damage to the inflation tube 4. The setting of the locking element 7 and the connecting part 35 can prevent the mounting frame 3 and the inflation tube 4 from accidentally passing through the storage cavity 11 during storage and transportation, which is convenient for the storage and transportation of the air pump 2.

[0038] The outer casing 1 of this utility model is provided with a power supply 8, which can store electrical energy, making it convenient for users to use the air pump 2 outdoors.

[0039] In this utility model, the locking member 7 and the connecting part 35 can be connected by a plug-in structure, a snap-fit ​​structure or other structures. When in use, the user can control the displacement of the locking member 7 or the connecting part 35 separately, thereby connecting or disengaging the locking member 7 and the connecting part 35.

[0040] When the locking member 7 and the connecting part 35 are connected by a snap-fit ​​structure, preferably, the connecting part 35 can be provided with a driving surface to control the mounting bracket 3 to move into the storage cavity 11. The driving surface can drive the locking member 7 to move and make the locking member 7 and the connecting part 35 cooperate. The driving surface facilitates the automatic cooperation between the locking member 7 and the connecting part 35, and makes it easy for the user to control the inflation tube 4 and the mounting bracket 3 to be quickly stored in the storage cavity 11, which is convenient for the storage of the air pump 2. In this structure, preferably, the locking member 7 is provided with an elastic arm. The driving surface can drive the locking member 7 to move and deform the elastic arm. The elastic arm can drive the locking member 7 to reset and make the locking member 7 cooperate with the connecting part 35.

[0041] The locking element 7 described in the accompanying drawings of this utility model is a press-lock buckle that controls the movement of the mounting bracket 3 into the storage cavity 11. The connecting part 35 can drive the locking element 7 to move, and make the connecting part 35 engage or disengage with the locking element 7, so that the inflation tube 4 can be stored in the storage cavity 11, or the inflation tube 4 can move with the mounting bracket 3 and pass out of the storage cavity 11. The press-lock buckle structure not only makes it easy for the user to control the inflation tube 4 and the mounting bracket 3 to be quickly stored in the storage cavity 11, but also makes it easy for the user to control the inflation tube 4 and the mounting bracket 3 to pass out of the storage cavity 11, which is convenient for the user.

[0042] Push-button latches are common latch structures widely used in home furnishings, appliances, and children's products, such as trash cans and microwave ovens. Since push-button latches are outsourced components, manufacturers can produce the corresponding parts according to our functional and installation requirements, which we can then assemble and use. Therefore, although this utility model does not specifically show the push-button latch structure, those skilled in the art can implement the technical solution of this utility model. The structure of a push-button latch is similar to the push-button switch in a push-button trash can as described in Chinese Utility Model Patent Application No. CN200720056442.3.

[0043] The air pump 2 is equipped with a connecting pipe 21, and the inflation pipe 4 is equipped with a connecting rod 41. The connecting rod 41 is movably connected to the connecting pipe 21. The air pump 2 delivers gas to the inflation pipe 4 through the connecting pipe 21 and the connecting rod 41. The mounting frame 3 is controlled to move relative to the outer shell 1. The inflation pipe 4 can move with the mounting frame 3 and cause the connecting rod 41 to move relative to the connecting pipe 21. The movably connected connecting rod 41 and connecting pipe 21 can prevent the inflation pipe 4 from deforming during the relative movement of the mounting frame 3 and the outer shell 1, thus avoiding damage to the inflation pipe 4 or the connection position between the inflation pipe 4 and the air pump 2, which helps to extend the service life of the air pump 2.

[0044] The connecting tube 21 of this utility model is provided with a hinge hole 22. The connecting rod 41 is rotatably connected to the hinge hole 22 and can move along the axial direction of the hinge hole 22. The extension of the inflation tube 4 is controlled. The hinge part can rotate relative to the hinge hole 22 and make the inflation tube 4 and the mounting frame 3 rotate relative to each other. The setting of the connecting rod 41 and the hinge hole 22 allows the inflation tube 4 and the mounting frame 3 to rotate relative to each other, which makes it convenient for the user to flexibly control the connection between the inflation tube 4 and the inflated item, and is convenient for the user to use.

[0045] In this embodiment, the connecting rod 41 is provided with a hinge protrusion 43, and the hinge protrusion 43 and the hinge part are respectively provided on both sides of the connecting rod 41. The mounting frame 3 is provided with a hinge groove 37 that is adapted to the hinge protrusion 43. The inflation tube 4 is controlled to detach from the mounting frame 3 and rotate relative to the hinge groove 37. The setting of the hinge protrusion 43 and the hinge groove 37 facilitates the stable rotation of the inflation tube 4 and the mounting frame 3, and avoids the hinge part from deflecting to the side of the hinge hole 22 during the use of the air pump 2, which would cause damage to the hinge part and the hinge hole 22, and helps to extend the service life of the air pump 2.

[0046] The inflation tube 4 is provided with a connecting rod 41 and a connector 42 for connecting to the inflated item at both ends. Preferably, a sealing ring 411 is fitted on the connecting rod 41 and the sealing ring 411 abuts against the hinge hole 22.

[0047] The mounting bracket 3 is slidably disposed in the storage cavity 11. The mounting bracket 3 has a mounting groove 31 on its outer periphery. The inflation tube 4 is a flexible hose. The inflation tube 4 can be wound around the mounting bracket 3 and stored in the mounting groove 31. The mounting groove 31 facilitates the winding and storage of the inflation tube 4, avoids knotting of the inflation tube 4, and makes it convenient for the storage and extension of the inflation tube 4, making it convenient for the user.

[0048] In this invention, the mounting groove 31 has several abutting protrusions 33 spaced apart on its side wall. The abutting protrusions 33 press against the inflation tube 4 and fix the inflation tube 4 in the mounting groove 31. The abutting protrusions 33 can reduce the friction between the inflation tube 4 and the mounting groove 31, making it easier for the user to control the retraction and extension of the inflation tube 4. They can also prevent the inflation tube 4 and the mounting groove 31 from being severely worn after long-term use, which would affect the stable installation of the inflation tube 4.

[0049] In this embodiment, the abutting protrusion 33 preferably has a guide surface 34 at one end near the outer periphery of the mounting groove 31. The inflation tube 4 can be guided and installed onto the side of the abutting protrusion 33 through the guide surface 34. This structure makes it easy for the user to control the inflation tube 4 to be quickly stored in the mounting groove 31.

[0050] The mounting frame 3 is provided with several guide rods 32, and the outer shell 1 is provided with guide grooves 12 that are adapted to the guide rods 32. The guide rods 32 and guide grooves 12 are slidably connected, and the guide rods 32 are provided with limit grooves 321. The side wall of the guide groove 12 is provided with limit protrusions 13 that are adapted to the limit grooves 321. The elastic element 5 drives the mounting frame 3 to reset and makes the limit protrusions 13 abut against the end of the limit grooves 321. The arrangement of the guide rods 32 and the guide grooves 12 facilitates the stable sliding of the mounting frame 3 and the outer shell 1, while the limit grooves 321 and limit protrusions 13 can limit the range of motion of the mounting frame 3 and the outer shell 1, so that the mounting frame 3 and the outer shell 1 can swing freely during the use of the air pump 2, which is convenient for the user.

[0051] In this invention, the elastic element 5 is disposed in the guide groove 12. During the relative movement of the mounting frame 3 and the outer shell 1, the guide rod 32 can be driven to compress along the length direction of the guide groove 12. Since the elastic element 5 is disposed in the guide groove 12, the elastic element 5 can be stably deformed during the relative movement of the mounting frame 3 and the outer shell 1, thus avoiding the bending deformation of the elastic element 5 from affecting the reset of the mounting frame 3.

[0052] In this embodiment, the guide rod 32 is provided with limiting grooves 321 on both sides, and the guide groove 12 is provided with limiting protrusions 13 that are adapted to the limiting grooves 321 on both sides. In this embodiment, the elastic element 5 is a compression spring, and the guide groove 12 is provided with elastic elements 5.

[0053] This application relates to the air pump 2 and the circuit control section. The air pump 2 is a well-known technology in the industry. Therefore, although this utility model does not specifically describe this part, those skilled in the art can implement the structure of inflation through the air pump 2 and the inflation tube 4 based on their own knowledge. The controller 6 is an outsourced component. According to our functional and installation requirements, the outsourced manufacturer can produce the corresponding accessories, which we can then assemble and use. Therefore, although this utility model does not specifically show the structure of the controller 6, those skilled in the art can implement the technical solution of this utility model.

[0054] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
