Description

Technical Field

[0001] This utility model relates to the field of air pump technology, specifically a protective structure for an air pump. Background Technology

[0002] In scenarios such as emergency car inflation and outdoor equipment inflation, handheld air pumps have become an important tool for ensuring tire pressure and maintaining equipment performance due to their portability and efficiency. With the diversification of travel needs and the popularization of outdoor activities, users are constantly increasing their requirements for the reliability and durability of air pumps. Their structural design needs to take into account both portability and impact resistance to adapt to complex usage environments (such as vehicle bumps and outdoor collisions), driving the development of air pump protection technology towards a more comprehensive and reliable direction.

[0003] The existing handheld air pump mainly consists of a main body (integrating an inflation module, pressure monitoring module, and control buttons), an inflation hose, a metal connecting pipe, an air nozzle connector, and an air nozzle locking buckle. The air nozzle locking buckle is rotatably mounted on the air nozzle connector via a connecting shaft, used to lock the air nozzle during inflation and prevent it from falling off. During operation, the user connects the air nozzle connector to the tire valve, rotates the air nozzle locking buckle to lock it, and then starts the main body to begin inflation. The pressure monitoring module provides real-time feedback of air pressure data, and the control buttons enable inflation start / stop and mode adjustment. This structure relies on the mechanical locking function of the air nozzle locking buckle to ensure the stability of the inflation process and meet basic usage requirements.

[0004] The valve locking clips and valve connectors of existing air pumps are directly exposed to the external environment, making them susceptible to bumps and impacts. Since most valve locking clips on the market are made of plastic, they are easily broken and damaged when impacted. Even if metal is used, the connecting shaft is relatively small and is easily deformed or broken after impact, causing the locking function to fail and the air pump to malfunction. This results in a relatively short service life for existing handheld air pumps. Therefore, there is an urgent need to develop a protective structure for air pumps to solve these problems. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a protective structure for an air pump to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective structure for an air pump, comprising a structural body and an air pump body, wherein the structural body is disposed on a pump housing within the air pump body, and the structural body includes a protective groove formed on the outer wall of the pump housing for placing an air nozzle connector and an air nozzle locking buckle in the air pump body; a support plate for supporting the pump housing is slidably installed inside the outer wall of the pump housing, and a spring connected to the pump housing is installed at the bottom of the support plate; The main body of the structure also includes a pipe seat and a pipe buckle installed on the outer wall of the pump body. The pipe seat is used to restrict the position of the metal connecting pipe in the air pump body, and the pipe buckle is used to restrict the position of the air charging pipe in the air pump body. The bottom of the pipe seat is located outside the protective groove and covers the top of the air nozzle locking buckle. After the metal connecting pipe is clamped onto the pipe seat, the end of the air nozzle connector is in contact with the inner wall of the protective groove, and at this time the top of the air nozzle locking buckle is restricted by the bottom of the pipe seat.

[0007] By adopting the above technical solution, the protective groove houses the air nozzle connector and air nozzle locking buckle, and the pipe seat and pipe buckle fix the metal connecting pipe and the air inlet pipe to avoid exposure to impact. The support plate and spring work together to enhance fixation and extend service life.

[0008] Furthermore, the outer end of the support plate protrudes from the pump body shell, and the width of the outer end of the support plate is greater than the width of the protective groove. A buffer wheel that is in contact with the outer wall of the pump body shell is rotatably installed on the inner wall of the outer end of the support plate.

[0009] By adopting the above technical solution, the buffer wheel reduces sliding friction, ensuring that the support plate rises and falls smoothly.

[0010] Furthermore, the bottom of the support plate is equipped with multiple sets of limiting rods that are slidably connected to the pump body shell, and the outer wall of each limiting rod is fitted with a spring, and the pump body shell is provided with mounting grooves corresponding to the limiting rods and springs.

[0011] By adopting the above technical solution, multiple sets of limit rods guide the support plate to slide, preventing the support plate from shifting and ensuring stable support for the air nozzle connector.

[0012] Furthermore, a limiting groove corresponding to the support plate is provided inside the pump body shell, and the limiting groove is connected to the protective groove. The distance between the inner wall of the limiting groove and the outer wall of the pump body shell is greater than the distance between the protective groove and the outer wall of the pump body shell.

[0013] By adopting the above technical solution, the limiting groove provides sufficient space for the support plate to rise and fall, preventing it from sliding excessively and ensuring smooth storage and removal of the air nozzle connector.

[0014] Furthermore, an outer protective plate is installed on the bottom surface of the middle part of the support plate, which is slidably connected to the outer wall of the pump body shell. This outer protective plate is used to cover the limiting groove, the limiting rod, and the spring, and its length is greater than the distance the support plate can move up and down.

[0015] By adopting the above technical solution, the outer protective plate covers the limiting groove, limiting rod and spring, and the length is adapted to the lifting distance of the support plate, preventing large particles of impurities from entering and affecting operation, and improving structural durability.

[0016] Furthermore, the opening width of the tube seat and the tube buckle is smaller than the diameter of the corresponding metal connecting tube and the air inlet tube, and the inner wall of the opening position of the tube seat and the tube buckle is made of rubber material.

[0017] By adopting the above technical solution, the rubber inner wall firmly clamps the metal connecting pipe and the inflation pipe.

[0018] Furthermore, the distance between the bottom surface of the tube seat and the top surface of the protective groove is less than the distance of the support plate sliding up and down, and a guide wheel for guiding the nozzle locking buckle is rotatably installed at the bottom of the tube seat near the corner of the protective groove. When the nozzle connector moves out of the protective groove, the nozzle locking buckle will contact the guide wheel.

[0019] By adopting the above technical solution, the guide wheel guides the air nozzle locking buckle to unfold, making it easy to remove the air nozzle connector.

[0020] In summary, the present invention has the following main advantages: This utility model achieves both protection and ease of use through multiple collaborative designs. The protective groove houses the air nozzle connector and the air nozzle locking buckle, while the pipe seat and pipe buckle respectively fix the metal connecting pipe and the inflation pipe, preventing the components from being exposed and damaged. The support plate is pressed upward under the action of the spring, and together with the pipe seat, it blocks and restricts the air nozzle locking buckle, enhancing the fixing effect. Components such as buffer wheels and guide wheels reduce friction and collision, and the outer protective plate protects the internal structure. Overall, it takes into account both protection reliability and ease of operation, and extends the service life of the air pump. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A protective structure for an air pump, such as Figure 1 - Figure 6 As shown, the air pump body includes a structural body and an air pump body consisting of a pump housing 1, an air inlet pipe 2, a metal connecting pipe 3, an air nozzle connector 4, and an air nozzle locking buckle 5. The structural body is installed on the pump housing 1 of the air pump body and is used to protect the key components of the air pump.

[0026] The structural body in this embodiment specifically includes components such as a protective groove 6, a support plate 7, a pipe seat 13, and a pipe buckle 14; Among them, the protective groove 6 is opened on the outer wall of the pump body shell 1 to house the air nozzle connector 4 and the air nozzle locking buckle 5 in the air pump body, so as to prevent the two from being directly exposed to the external environment. Secondly, the support plate 7 is slidably installed inside the outer wall of the pump body shell 1 to support the pump body shell 1 and assist in fixing the air nozzle connector 4. At the same time, a spring 10 connected to the pump body shell 1 is installed at the bottom of the support plate 7, and the spring 10 provides an upward elastic force to the support plate 7. Both the pipe seat 13 and the pipe buckle 14 are installed on the outer wall of the pump body shell 1; The tube seat 13 is used to restrict the position of the metal connecting tube 3 in the air pump body, and the tube buckle 14 is used to restrict the position of the air charging tube 2 in the air pump body. At the same time, the bottom of the tube seat 13 is located outside the protective groove 6, which can cover the top of the air nozzle locking buckle 5 and enhance the protective effect. When the metal connecting tube 3 is locked on the tube seat 13, the end of the air nozzle connector 4 is in contact with the inner wall of the protective groove 6. At this time, the top of the air nozzle locking buckle 5 is restricted by the bottom of the tube seat 13 to prevent it from accidentally coming out.

[0027] For example, the outer end of the support plate 7 protrudes from the pump housing 1, making it easier for the user to press the support plate 7 later, thereby reducing the difficulty of inserting the air nozzle connector 4 and the air nozzle locking buckle 5 into the protective groove 6. The width of the outer end is greater than the width of the protective groove 6. At the same time, a buffer wheel 12 is rotatably installed on the inner wall of the outer end of the support plate 7. The buffer wheel 12 is in contact with the outer wall of the pump housing 1, reducing friction when the support plate 7 slides, and supporting the outer end of the support plate 7 to prevent the support plate 7 from changing angle.

[0028] In this embodiment, multiple sets of limiting rods 9 are installed at the bottom of the support plate 7. The limiting rods 9 are slidably connected to the pump body shell 1. Springs 10 are sleeved on the outer wall of each rod. The pump body shell 1 has mounting grooves corresponding to the limiting rods 9 and springs 10. The limiting rods 9 are used to guide the support plate 7 to rise and fall, and prevent it from deviating. Meanwhile, a limiting groove 8 corresponding to the support plate 7 is provided inside the pump body shell 1. The limiting groove 8 is connected to the protective groove 6, and the distance between the inner wall of the limiting groove 8 and the outer wall of the pump body shell 1 is greater than the distance between the protective groove 6 and the outer wall of the pump body shell 1. This provides sufficient sliding space for the support plate 7 and restricts the sliding trajectory of the support plate 7 to prevent the support plate 7 from moving too far upward, which could lead to an accident where the pressure on the air nozzle locking buckle 5 is too high.

[0029] In this embodiment, an outer protective plate 11 is installed on the bottom surface of the middle part of the support plate 7. The outer protective plate 11 is slidably connected to the outer wall of the pump body shell 1 and is used to shield the limiting groove 8, the limiting rod 9 and the spring 10 to prevent large particles from entering the limiting groove 8 and affecting the operation of the limiting rod 9, the support plate 7 and the spring 10. The length of the outer protective plate 11 is greater than the lifting distance of the support plate 7, ensuring that it can always play a shielding role during the sliding process of the support plate 7.

[0030] For example, the opening width of the pipe seat 13 and the pipe buckle 14 is smaller than the diameter of the corresponding metal connecting pipe 3 and the air inflator 2, and the inner wall of the opening is made of rubber, which can not only firmly clamp the corresponding metal connecting pipe 3 and the air inflator 2, but also avoid scratching the pipe. The distance between the bottom surface of the tube seat 13 and the top surface of the protective groove 6 is less than the distance of the support plate 7 sliding up and down, ensuring that after the support plate 7 slides down, the air nozzle connector 4 and the air nozzle locking buckle 5 can be smoothly pushed into the protective groove 6; a guide wheel 15 is rotatably installed at the bottom of the tube seat 13 near the corner of the protective groove 6. The guide wheel 15 is used to guide the air nozzle locking buckle 5. When the air nozzle connector 4 moves out of the protective groove 6, the air nozzle locking buckle 5 will contact the guide wheel 15, so that it can be smoothly unfolded. Through the coordinated operation of the above components, when storing, the air nozzle connector 4 and the air nozzle locking buckle 5 are placed into the protective groove 6, the metal connecting tube 3 is inserted into the tube seat 13, and the inflation tube 2 is inserted into the tube buckle 14. The support plate 7 pushes the air nozzle connector 4 upward under the action of the spring 10, which, together with the tube seat 13, covers the air nozzle locking buckle 5 to achieve protection. When using it in the future, pulling the metal connecting tube 3 or the inflation tube 2 will bring the air nozzle connector 4 out of the protective groove 6. The guide wheel 15 guides the air nozzle locking buckle 5 to unfold. The operation is convenient and effectively extends the service life of the air pump.

[0031] The working principle of this utility model is as follows: When the air pump body is finished and the inflation pipe 2, metal connecting pipe 3, air nozzle connector 4, and air nozzle locking buckle 5 need to be stored and protected, first press the support plate 7 downward through the end of the air nozzle connector 4, so that the support plate 7 drives the limiting rod 9 and the outer protective plate 11 to slide downward, causing part of the limiting groove 8 to be exposed. Since the limiting groove 8 is connected to the protective groove 6, part of the opening of the limiting groove 8 will be exposed, making it easy for the user to push the air nozzle locking buckle 5 and the air nozzle connector 4 into the protective groove 6. Then, the user pushes the air nozzle connector 4 and the air nozzle locking buckle 5 into the protective groove 6 until the end of the air nozzle connector 4 is in contact with the inner wall of the protective groove 6. At this time, the metal connecting pipe 3 also smoothly enters the pipe seat 13. Since the inner wall of the opening at the end of the pipe seat 13 is made of rubber material, it will restrict the position of the metal connecting pipe 3. At this time, the user can release the air nozzle connector 4. The rear support plate 7 moves upward under the action of multiple sets of springs 10, thereby pushing the air nozzle connector 4 and the air nozzle locking buckle 5 upward until the top surface of the support plate 7 is in contact with the limiting groove 8. At this time, the air nozzle locking buckle 5 is pushed to the state where its end is in contact with the top surface of the protective groove 6. Because part of the opening of the protective groove 6 is blocked by the bottom of the tube seat 13, the top of the air nozzle locking buckle 5 will be blocked by the tube seat 13 and cannot move directly outward. With the support plate 7 giving the air nozzle connector 4 an upward push, and the tube seat 13 restricting the metal connecting tube 3, the position of the air nozzle connector 4 and the air nozzle locking buckle 5 in the protective groove 6 is restricted. Since the air nozzle connector 4 and the air nozzle locking buckle 5 are both located in the protective groove 6 and are not directly exposed to the external environment, the air nozzle locking buckle 5 is prevented from being impacted when not in use. Then the inflation tube 2 is locked on the corresponding tube buckle 14 to restrict the inflation tube 2. When the air nozzle connector 4 is needed, pull the inflation tube 2 or the metal connecting tube 3 or the air nozzle connector 4 to pull the air nozzle connector 4 outward into the protective groove 6. As the air nozzle connector 4 and the metal connecting tube 3 slide outward, the air nozzle locking buckle 5 will move outward synchronously with the air nozzle connector 4. As the air nozzle locking buckle 5 moves outward, its top will contact the guide wheel 15, causing it to begin to change angle. Thus, when the air nozzle connector 4 is completely pulled out of the protective groove 6, the distance between the top outer wall of the air nozzle locking buckle 5 and the metal connecting tube 3 is convenient for the user to pull and rotate the air nozzle locking buckle 5. This makes the distance between the top of the air nozzle locking buckle 5 and the metal connecting tube 3 larger during the process of pulling out the air nozzle connector 4, which is convenient for subsequent operations. Of course, in non-emergency situations, you can also press down on the nozzle connector 4 to make the support plate 7 slide down, so that the nozzle connector 4 drives the nozzle locking buckle 5 to be misaligned with the pipe seat 13, and then pull the nozzle connector 4 outward. In the same way, the nozzle connector 4 and the nozzle locking buckle 5 can be taken out smoothly.

[0032] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
