Description

Technical Field

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

[0002] A kayak inflatable pump is a tool for quickly inflating a kayak. There are various types, including electric inflatable ones that use a motor to drive a compressor to work. By compressing air and discharging the air into the kayak interior, rapid inflation is achieved.

[0003] During application, according to the interface sizes of the inflatable pump and the kayak inflation valve, a suitable connecting pipe will be selected for connection. The connection method mostly uses threaded connection. However, since the equipment often needs to be used in complex and changeable outdoor environments, it will inevitably be affected by external forces such as vibration and impact. If these external forces accumulate over a long time or the instantaneous intensity is too large, it is possible that the originally tightened threaded connection shows signs of loosening. To further improve the connection stability, a kayak inflatable pump is proposed. Summary of the Utility Model

[0004] In view of the deficiencies in the prior art, the utility model provides a kayak inflatable pump. The kayak air intake pipe and the power supply wire are connected by a threaded connector. To ensure the stability of the connection between the threaded connector and the power supply wire, there is a mutual cooperation of an outer limiting ring, a limiting slot, and a positioning rod. When the threaded connector is rotated into the power supply wire, it drives the positioning rod to be inserted into the limiting slot for lateral limitation. A sleeve cover is rotatably sleeved on the positioning rod and can exert a pressure towards the inflatable pump body on the outer limiting ring, thereby performing longitudinal limitation. In this way, when the power supply wire is connected to the kayak air intake pipe, some influences caused by external forces can be reduced, the loosening risk can be lowered, and at the same time, the connection stability can be improved.

[0005] To solve the above technical problems, the utility model solves the problem of further improving the connection stability of the kayak inflatable pump during application through the following technical solutions.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A kayak inflatable pump includes an air pump outlet provided on the inflatable pump body. A kayak air intake pipe with a pipe interface is provided at the air pump outlet. The kayak air intake pipe is connected to the air pump outlet through a threaded connector. An outer limiting ring with a limiting slot is provided outside the threaded connector. A positioning rod is provided on the inflatable pump body and is clamped in the limiting slot and is threadedly connected with a sleeve cover.

[0008] Preferably, an interface sleeve with an anti-slip convex layer is provided outside the air pump outlet.

[0009] Preferably, the anti-slip convex layer is evenly distributed on the surface of the interface sleeve and is in a state of mutual extrusion with the outer limit ring.

[0010] Preferably, the two ends of the outer limit ring are provided with arc-shaped guide plates, and the pipe interface is located therein and is threadedly connected with the threaded connector.

[0011] Preferably, the bottom of the positioning rod is connected with a fixing plate, and a support member is provided on the fixing plate to connect it with the air pump body.

[0012] Preferably, one end of the positioning rod extending out of the limit slot is provided with a thread, and the thread enables the cover to be connected thereto and to contact the outer limit ring.

[0013] Preferably, an outer stabilizing ring is adhesively attached to the end of the cover contacting the outer limit ring, and the outer stabilizing ring is designed with a rubber material.

[0014] Preferably, support bottoms are provided at the four corners of the back of the air pump body, and anti-slip pads are provided on the support bottoms for anti-slip.

[0015] Preferably, a power connection wire is provided on the air pump body, and a plurality of wire clamping hoops are evenly distributed at one end of the air pump body facing the air pump outlet.

[0016] Preferably, the plurality of wire clamping hoops are all connected to the side of the air pump body through a connecting plate.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] The kayak air pump provided in this application connects the kayak air pipe and the air pump outlet through a threaded connector. In order to ensure the stability of the connection between the threaded connector and the air pump outlet, the outer limit ring, the limit slot and the positioning rod cooperate with each other. When the threaded connector is rotated into the air pump outlet, the positioning rod is driven to be inserted into the limit slot for lateral limitation. The positioning rod is rotatably sleeved with a cover, which can apply pressure to the outer limit ring towards the air pump body for longitudinal limitation. In this way, when the air pump outlet is connected to the kayak air pipe, some influences caused by external forces can be reduced, the risk of loosening can be reduced, and the stability of the connection can be improved.

[0019] This application is provided with guide plates, and the guide plates are provided with arcs. When the pipe interface is rotated to make the upper part of the threaded connector threadedly connected thereto, the pipe interface is located inside the guide plates on both sides, so as to perform a limiting operation on it.

[0020] This application is provided with a positioning rod and a support member. After the positioning rod enters from the opening of the limit slot, the outer limit ring is located above the fixing plate, which can limit the outer limit ring, and the support member can support and fix the overall structure on the fixing plate.

[0021] By providing an outer stabilizing ring in this application, the outer stabilizing ring can increase the friction force of the contact surface, making the contact between the cover and the outer limiting ring more stable and improving the limiting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Please refer to Figure 1 - Figure 7 , a kayak inflator, including an air pump outlet 101 provided on the inflator body 1. A kayak connecting air pipe 2 with a pipe interface 201 is provided at the air pump outlet 101. The kayak connecting air pipe 2 is connected to the air pump outlet 101 through a threaded connector 3. An outer limiting ring 4 with a limiting slot 401 is provided outside the threaded connector 3. A positioning latch 601 is provided on the inflator body 1 and is clamped in the limiting slot 401 and is threadedly connected with a cover 602.

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, the kayak inflator of the present application mainly consists of an inflator body 1, an air pump outlet 101, a power connection wire 102 and other structures used in combination. During the application process, a kayak connecting tube 2 is connected at the air pump outlet 101 and connected to the kayak inflation valve port. A tube interface 201 is provided on the kayak connecting tube 2. The kayak connecting tube 2 and the tube interface 201 are integrally structured. One end of it is threadedly connected into the air pump outlet 101 through a threaded connector 3, and the other end is threadedly connected to the inside of the tube interface 201. When connecting to the air pump outlet 101, an outer limit ring 4 is provided outside the threaded connector 3 to separate the air pump outlet 101 from the tube interface 201. Limit slots 401 are opened on both sides of the outer limit ring 4. A fixed positioning rod 601 is provided on the periphery of the air pump outlet 101, that is, on the inflator body 1. When the threaded connector 3 is rotated into the air pump outlet 101, it also drives the positioning rod 601 to be inserted into the limit slot 401. While making lateral limitation in this way, a thread is provided at one end of the positioning rod 601 extending out of the limit slot 401. This thread cooperates with the internal thread of the cover 602, so that while the cover 602 is rotated and sleeved thereon, a pressure towards the inflator body 1 is applied to the outer limit ring 4 to make longitudinal limitation. In this way, when the air pump outlet 101 is connected to the kayak connecting tube 2, some influences caused by external forces can be reduced, the loosening risk can be lowered, and the stability of the connection can be improved.

[0037] An interface sleeve 5 and an anti-slip convex layer 501 are also provided in the present application. The anti-slip convex layer 501 is evenly distributed on the upper surface of the interface sleeve 5. When the interface sleeve 5 is sleeved outside the interface of the air pump outlet 101, due to the elasticity of the provided interface sleeve 5 and the anti-slip convex layer 501 being made of rubber material, when the threaded connector 3 is connected to the air pump outlet 101 and the outer limit ring 4 limits the opening of the air pump outlet 101, a mutual extrusion force can be generated between its bottom and the anti-slip convex layer 501. In this way, while increasing the friction at the connection, the stability is also ensured.

[0038] A guide plate 402 is also provided in the present application. The guide plate 402 is fixedly installed on both sides of the top of the outer limit ring 4 and has a curvature. When the tube interface 201 is rotated to make the upper part of the threaded connector 3 threadedly connected thereto, the tube interface 201 can be located inside the guide plates 402 on both sides. While performing a limiting operation on it in this way, a guiding operation can be performed during the rotational connection to prevent the problem of deviation during the connection.

[0039] In this application, a positioning rod 601 and a support member 7 are also provided. The positioning rod 601 and the positioning rod 601 are designed as an integral structure. When the positioning rod 601 enters and is clamped in the limit slot 401 from the opening of the limit slot 401, the outer limit ring 4 is positioned above the fixing plate 6 to limit the outer limit ring 4. The support member 7 is fixedly installed at the bottom of the fixing plate 6, and the bottom of the support member 7 is connected to the air pump body 1 by gluing, so as to support and fix the overall structure above the fixing plate 6.

[0040] In this application, an outer stabilizing ring 603 is also provided. The outer stabilizing ring 603 is designed with a rubber material and is glued to the outer ring at the bottom of the sleeve cover 602. When the sleeve cover 602 is rotated and connected to the positioning rod 601 and pressure is applied to the outer limit ring 4 to contact it, the friction between the two contact surfaces can be increased, making the contact between the sleeve cover 602 and the outer limit ring 4 more stable and improving the limiting effect.

[0041] Please refer to Figure 2 and Figure 3 In this application, a support base 9 and an anti-slip pad 901 are also provided. The support base 9 is arranged at the four corners on the back of the air pump body 1, so that when used in the outside world, the air pump body 1 is erected and used by the support base 9. While preventing direct contact and wear, the anti-slip pad 901 is glued to the side where the support base 9 is placed and is designed with a rubber material. Therefore, when placed, it can increase the contact area of the placement surface and also enhance the stability during the placement process.

[0042] In this application, a connecting plate 8 and a wire clamp 801 are also provided. The power connection wire 102 is used to connect the air pump body 1 to the power supply. The connecting plate 8 is glued to the side of the air pump body 1, so that a plurality of wire clamps 801 can be rotatably connected thereto. The wire clamp 801 has an opening and is elastic, so that when storing or arranging the wires at the air pump outlet 101, it can be fixed and the convenience during storage can also be improved.
