Description

Technical Field

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

[0002] Inflatable tents are popular among consumers due to their sturdy structure and ease of carrying. To use them, simply inflate the tent's air hoses using an air pump, causing the air hoses to form the tent's frame structure. To prevent the inability to inflate the tent if the air pump is lost during outdoor use, it is usually sewn or welded to the inflation port of the tent's air hoses. However, this method requires an additional hole for the air pump to be connected to a power source, resulting in high manufacturing costs and a complex, easily damaged structure. Utility Model Content

[0003] The purpose of this invention is to provide a circuit connection structure for an air pump to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An air pump circuit connection structure includes an air inlet, a power connector, and a sealing cap. The air inlet has an air inlet that runs vertically through it. An installation ring is fixedly connected to the inner wall of the air inlet by a connecting rib. An air inlet gap is provided between the outer wall of the installation ring and the inner wall of the air inlet. The power connector is inserted into the installation ring and connected to the air pump body. The sealing cap is detachably placed on the air inlet of the air inlet.

[0006] Preferably, the top end of the power connector is provided with a limiting part, and the outer diameter of the limiting part is larger than the inner diameter of the mounting ring.

[0007] Preferably, a connecting sleeve is fixedly connected to the side wall of the air pump body, and the bottom end of the air inlet is detachably inserted into the connecting sleeve through a threaded structure. A clamping structure for clamping and fixing the tent air hose tarpaulin is formed between the inner wall of the air inlet and the outer wall of the connecting sleeve and above the threaded structure.

[0008] Preferably, the threaded structure includes an internal thread on the inner wall of the connecting sleeve and an external thread on the outer wall of the air inlet. The tent air hose tarpaulin is fitted outside the housing of the air pump body and extends from the outer wall of the connecting sleeve into the inner wall of the connecting sleeve, where it is clamped and fixed by the clamping structure.

[0009] Preferably, the inner wall of the connecting sleeve and above the internal thread is provided with a sloping surface, and an upper step is provided on the sloping surface. The upper outer wall of the air inlet extends outward to form a fixing ring, and the outer wall of the fixing ring is provided with a lower step that cooperates with the upper step to form the clamping structure.

[0010] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] This utility model provides a circuit connection structure for an air pump. An installation ring for fixing the power connector is set inside the air inlet of the air inlet nozzle. In use, the air inlet is opened and the wire harness is directly inserted into the power connector. External gas enters the air pump through the air inlet gap between the installation ring and the air inlet nozzle to inflate the tent air tube. The power supply structure of the air pump is integrated into the air inlet. The structure is simple, the manufacturing cost is low, and it is convenient to use and has good practicality.

[0021] Please refer to Figures 1 to 7As shown, this utility model discloses a circuit connection structure for an air pump, including an air inlet 1, a power connector 2, and a sealing cover 3. The air inlet 1 is provided with an air inlet 11 that runs vertically through the air inlet. The inner wall of the air inlet 11 is fixedly connected to an mounting ring 13 by a connecting rib 12. An air inlet gap 14 is provided between the outer wall of the mounting ring 13 and the inner wall of the air inlet 11. The power connector 2 is inserted into the mounting ring 13 and connected to the air pump body 4. The sealing cover 3 is detachably placed on the air inlet 11 of the air inlet 1.

[0022] The top of the power connector 2 is provided with a limiting part 21. The outer diameter of the limiting part 21 is larger than the inner diameter of the mounting ring 13 to prevent the power connector 2 from being inserted too deeply.

[0023] The air pump body 4 is inserted into the connection port 51 of the tent air pipe 5. The air pump body 4 includes a housing 41 and a pump body 42. The pump body 42 is installed inside the housing 41. A connecting sleeve 43 is provided on the side wall of the housing 41 and communicates with the housing 41. The bottom end of the air inlet 1 is detachably inserted into the connecting sleeve 43 through a threaded structure 44. A clamping structure 45 for clamping and fixing the tent air pipe 5 tent fabric is formed between the inner wall of the air inlet 1 and the outer wall of the connecting sleeve 43.

[0024] The threaded structure 44 includes an internal thread 441 on the inner wall of the connecting sleeve 43 and an external thread 442 on the outer wall of the air inlet 1. The tent air pipe 5 is covered by the tent fabric outside the shell 41 and extends from the outer wall of the connecting sleeve 43 into the inner wall of the connecting sleeve 43, where it is clamped and fixed by the clamping structure 45.

[0025] A ramp 431 is provided on the inner wall of the connecting sleeve 43 above the internal thread 441. An upper step 432 is provided on the ramp 431. A fixing ring 15 is formed by extending the upper outer wall of the air inlet 1 outward. A lower step 16 is provided on the outer wall of the fixing ring 15, which cooperates with the upper step 432 to form a clamping structure 45. The tent air pipe 5 tent fabric extends from the outer wall of the connecting sleeve 43 into the inner wall of the connecting sleeve 43. The air inlet 1 is fixedly connected to the connecting sleeve 43 by the cooperation of the internal thread 441 and the external thread 442. At the same time, the tent air pipe 5 tent fabric is fixed to the clamping structure 45 between the inner wall of the connecting sleeve 43 and the outer wall of the air inlet 1.

[0026] A support ring 433 extends inward from the inner wall of the connecting sleeve 43 and below the internal thread 441. The lower end of the air inlet 1 is provided with an insertion part 17 that passes through the support ring 443. A sealing ring 18 is fitted on the outer wall of the insertion part 17, and the sealing ring 18 is located between the support ring 443 and the thread structure 44, thereby achieving a sealing effect between the air inlet 1 and the connecting sleeve 43.

[0027] The bottom surface of the sealing cover 3 is provided with a fixing hook 31, and the side wall of the fixing hook 31 is provided with a fixing groove 32 for the connecting rib 12 to be inserted. Insert the fixing hook 31 into the air intake gap 14, and then rotate the sealing cover 3 so that the connecting rib 12 is inserted into the fixing groove 32, thereby fixing the sealing cover 3 on the air intake port 11 of the air intake nozzle 1.

[0028] When in use, open the air inlet 11 of the air inlet 1 and directly plug the wiring harness into the power connector 2. External gas enters the air pump body 4 through the air inlet gap 14 between the mounting ring 13 and the air inlet 11 to inflate the tent air pipe 5.
