Description

Technical Field

[0001] This utility model relates to the field of outdoor air pump technology, specifically a prefabricated outdoor air pump. Background Technology

[0002] An outdoor air pump is an air pump specifically designed for outdoor activities. It is mainly used to quickly inflate outdoor equipment such as air mattresses, motorboats, and tents. The modular design of the outdoor air pump allows for easy storage when not in use, reducing space occupation. However, traditional outdoor air pumps do not provide adequate support and protection for the connecting wires, which can lead to the wires being pulled by gravity during use, causing the connection to loosen.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent No. CN221723011U, Publication Date: 2024-09-17) discloses an outdoor air pump, comprising a housing and two pump bodies fixed within the housing. At least some sections of the two pump bodies are parallel to each other, and these parallel sections are fixed together by a connecting mechanism, which includes either a detachable connecting mechanism or a welded connecting mechanism. The pump bodies are electrically connected to a power supply battery pack. This method utilizes the parallel arrangement of the two air pumps for inflation, and modular assembly improves disassembly and assembly efficiency while reducing the failure rate.

[0004] The aforementioned mechanism improves assembly and disassembly efficiency by using two air pumps in parallel for inflation and modular assembly. However, in actual use, setting up two air pumps increases the overall cost and the overall wear and tear during use, which in turn reduces the applicability of the entire system in subsequent use. Utility Model Content

[0005] The purpose of this utility model is to provide a modular outdoor air pump to solve the problem mentioned in the background art that traditional outdoor air pumps are not convenient to support the inflation connection position during use, resulting in the inflation connection position folding, which affects the air intake during inflation and thus affects the inflation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembled outdoor air pump, comprising an air pump body, wherein a fan blade is provided inside the air pump body, and an air inlet is installed at the top of the air pump body, and an air outlet is provided at the bottom of the air pump body; a plug-in interface is provided on the side of the air pump body, and a support mechanism for supporting the wire is rotatably connected to the outer side of the air pump body below the plug-in interface, the support mechanism including a hinge seat, and the hinge seat is rotatably connected to the outer side of the air pump body below the plug-in interface, and a support tray is installed at the bottom of the hinge seat by bolts; a threaded rod is threadedly connected to the front end of the hinge seat, and a handle is fixedly connected to the front end of the threaded rod; a threaded sleeve matching the threaded rod is provided at the rear end of the hinge seat; hinge blocks are hinged at both the front and rear ends of the air pump body, and a protective mechanism for protecting the plug-in interface is engaged at one end between the hinge blocks.

[0007] Furthermore, one end of the threaded rod passes through the air pump body and the hinge seat and extends into the interior of the threaded sleeve, and the support plate is located below the insertion interface.

[0008] Furthermore, a fixing block is provided on the side of the air pump body, and the fixing blocks are distributed at equal angles on the outside of the plug interface.

[0009] Furthermore, the protective mechanism includes a protective ring, which is sleeved on the outside of the air pump body, and a sealing ring is engaged with one side of the air pump body and the protective ring. The inner side of the protective ring is provided with internal threads.

[0010] Furthermore, a positioning block is provided on the side of the hinge block near the protective ring, and a positioning groove matching the positioning block is provided on the outer side of the protective ring.

[0011] Furthermore, the cross-section of the positioning groove is annular, and the outer side of the positioning block fits into the inner side of the positioning groove.

[0012] Furthermore, a connecting spring is wound around one end of the hinge block near the air pump body, and the hinge block and the air pump body form an elastic structure through the connecting spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the air pump body is powered by a wire, the remaining length of the wire will sag due to gravity after the wire is plugged in, pulling the wire connected to the plug outwards. This makes the connection of the wire unstable. Therefore, when plugging in the wire, the support tray can support the wire and reduce the sag of the wire. At the same time, the excess length of the wire can be stored and placed on the top of the support tray, thus achieving wire storage.

[0015] Furthermore, by rotating the handle, the threaded rod can be driven to rotate synchronously. The threaded rod and the threaded sleeve are connected by threads. When the threaded rod rotates, it will separate from the threaded sleeve by a certain distance, thereby loosening the connection between the hinge seat and the air pump body. This allows the angle of the support tray to be adjusted flexibly. After fixing the angle, by rotating the handle in the opposite direction, the handle drives the threaded rod to rotate and connect with the threaded sleeve by threads and lock it, thereby fixing the angle of the support tray and making it easier to use the support tray to support the wire.

[0016] Furthermore, by tightening the protective ring, the internal thread and the external thread of the wire are locked together, making the connection between the wire and the connector more stable. In addition, the sealing ring set at the connection between the protective ring and the air pump body can limit the position of the protective ring and prevent the protective ring from shaking and causing the locking to be insufficient.

[0017] 2. By pressing the hinge block, the angle of the hinge block itself deflects, connecting the protective ring with the air pump body. Then, the pressure applied to the hinge block is removed, allowing the hinge block to reset its angle through the elastic force of the connecting spring. At the same time, the positioning block engages with the positioning groove on the outside of the protective ring, thereby limiting and locking the position of the protective ring.

[0018] Furthermore, due to the annular groove of the positioning slot, the protective ring can be rotated during subsequent use to lock and protect the wires at the connector connection. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 5 The technical solution shown addresses the problem of traditional outdoor air pumps where the connecting wires are difficult to support and protect during use, leading to the wires being pulled by gravity and causing loosening at the connection. This modular outdoor air pump discloses a support mechanism including an air pump body 1. The air pump body 1 has a fan blade 18 inside, an air inlet 2 at its top, and an air outlet 3 at its bottom. A connector 5 is located on the side of the air pump body 1, and the outer side of the air pump body 1 below the connector 5 rotates... The movable connection includes a support mechanism for supporting the wire. The support mechanism includes a hinge seat 9, which is rotatably connected to the outside of the air pump body 1 below the plug interface 5. The bottom end of the hinge seat 9 is bolted with a support tray 10. The front end of the hinge seat 9 is threadedly connected with a threaded rod 12, and the front end of the threaded rod 12 is fixedly connected with a handle 11. The rear end of the hinge seat 9 is provided with a threaded sleeve 13 that matches the threaded rod 12. One end of the threaded rod 12 passes through the air pump body 1 and the hinge seat 9 and extends into the interior of the threaded sleeve 13. The support tray 10 is located below the plug interface 5.

[0028] In this example, the motor and blades inside the air pump body 1 work together. The motor drives the fan blades 18 to rotate. When the fan blades 18 rotate, they create a low-pressure area, drawing external gas into the air pump body 1. As the fan blades 18 continue to rotate, this gas is compressed and pushed towards the output end of the air pump body 1. Finally, the gas is output through the air outlet 3 to the object that needs to be inflated. When using the air pump body 1, it needs to be powered by a wire. After the wire is plugged into the connector 5, the remaining length of the wire will sag due to gravity and pull the wire connected at the connector 5 outward, resulting in an unstable connection. Therefore, the support tray 10 can support the wire during plugging to reduce the sag and also allow excess length to be supported. The wires are stored and placed on top of the support tray 10, thus achieving wire storage. When connecting the wires, the support angle of the support tray 10 can be adjusted to ensure the stability of the connection, making the wire connection more stable. By rotating the handle 11, the threaded rod 12 can be driven to rotate synchronously. The threaded rod 12 and the threaded sleeve 13 are threadedly connected. When the threaded rod 12 rotates, it will separate from the threaded sleeve 13 by a certain distance, thereby loosening the connection between the hinge seat 9 and the air pump body 1, allowing the angle of the support tray 10 to be flexibly adjusted. After fixing the angle, by rotating the handle 11 in the opposite direction, the handle 11 drives the threaded rod 12 to rotate and connect with the threaded sleeve 13 and lock it, thereby fixing the angle of the support tray 10.

[0029] Example 2: Figure 1 , Figure 2 and Figure 4 The technical solution shown here is designed to address the problem that when connecting the wire to the connector 5, the angle of connection may shift, resulting in unstable connection. The assembled outdoor air pump discloses a foolproof mechanism, in which a fixing block 6 is provided on the side of the air pump body 1, and the fixing blocks 6 are evenly distributed on the outside of the connector 5.

[0030] In this example, after the wire is connected to the connector 5, the fixing block 6 on the outside of the connector 5 can guide the connection position of the wire to avoid misalignment of the insertion direction. When inserting, the protective ring 4 is fitted on the outside of the wire. By screwing the protective ring 4, the internal thread 8 is locked with the thread on the outside of the wire, so that the insertion of the wire and the connector 5 can be more stable. In addition, the sealing ring 7 set at the connection between the protective ring 4 and the air pump body 1 can limit the position of the protective ring 4 and prevent the protective ring 4 from shaking and causing the locking to be not firm enough.

[0031] Example 3: Figure 1 , Figure 2 , Figure 5and Figure 6 The technical solution shown addresses the problem that the connector 5 is easily damaged by impact when directly exposed to the outside environment during use. This assembled outdoor air pump discloses a protective mechanism: hinge blocks 14 are hinged to both ends of the air pump body 1, and a protective mechanism for protecting the connector 5 is engaged at one end of the hinge blocks 14. The protective mechanism includes a protective ring 4, which is sleeved on the outside of the air pump body 1. A sealing ring 7 is engaged between the air pump body 1 and the protective ring 4 on one side. The inner side of the protective ring 4 has an internal thread 8. A positioning block 15 is provided on the side of the hinge block 14 near the protective ring 4, and a positioning groove 16 matching the positioning block 15 is opened on the outer side of the protective ring 4. The positioning groove 16 has an annular cross-section, and the outer side of the positioning block 15 fits against the inner side of the positioning groove 16. A connecting spring 17 is wound around the end of the hinge block 14 near the air pump body 1, and the hinge block 14 and the air pump body 1 form an elastic structure through the connecting spring 17.

[0032] In this example, by pressing the hinge block 14, the angle of the hinge block 14 is deflected, connecting the protective ring 4 with the air pump body 1. Then, the pressure applied to the hinge block 14 is removed, allowing the hinge block 14 to return to its original angle through the elastic force of the connecting spring 17. At the same time, the positioning block 15 engages with the positioning groove 16 on the outer side of the protective ring 4, thereby limiting and locking the position of the protective ring 4. Since the positioning groove 16 is an annular groove, the protective ring 4 can rotate during subsequent use to lock and protect the wires at the connector 5 connection.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
