Abstract

A clip-type inflation joint includes a joint body, a pressure injection device, and a clip assembly. The joint body has an inflation passage and an inlet port and an outlet port communicating the inflation passage with the outside. The pressure injection device is provided in the inflation passage of the joint body, and has a pressure injection passage communicated with the inflation passage and a pressure injection protrusion facing the outlet port. The clip assembly has two clipping sheets pivoted at the opposite sides of the joint body, and is capable of performing the clipping-loosing operation back and forth between a clipping position and a loosing position under an external force. When the clipping sheets are located at the loosing position, the clipping assembly moves away from the outlet port in order to loose a nozzle; when the clipping sheets are located at the clipping position, the clipping assembly movies toward the outlet port in order to clip the nozzle. As such, the convenience of inflation can be enhanced through a simpler operation.

Description

Clamped inflation joint

The present invention relates to an inflation joint, and more particularly to a clamped inflation joint.

According to the current leisure style, it is quite popular, and the bicycle with sports and environmental protection functions has caused a wave.

Bicycle tires are often inflated to ensure safety during riding. Inflating generally uses an inflatable device (such as a pump or an air pump) and is connected to an inflation joint to be connected to the air nozzle of the tire by the inflation joint to achieve the effect of inflation.

However, a conventionally known and commonly used inflation joint mainly has a joint body, a trigger rod disposed on the joint body and a pressing ring disposed in the joint body, to utilize the pull lever The rod acts to deform the compression ring to press or loosen the nozzle. However, such a conventional inflation joint structure is not straightforward in operation and has a problem in that it is difficult to handle, and the joint effect with the gas nozzle is not good, and there is often a problem of air leakage.

In view of the above, in order to improve the lack of conventional knowledge, it is an object of the present invention to provide a clamped inflation joint which is relatively easy to handle and straightforward.

Another object of the present invention is to provide a clamp-type inflation joint which is combined with the air nozzle by a clamping method, so that the effect of the combination is better and the air leakage is not easy.

Therefore, in order to achieve the above object, the present invention provides a pinch-type inflation joint, which mainly comprises: a joint body having an inflation flow passage therein, and the outer side of the joint body has a communication flow passage to An input port and an output port; an injector is disposed in the inflation flow passage of the joint body, and has an injection flow passage communicating with the inflation flow passage and a pressure injection toward the outlet a clamping portion; a clamping component having two clips pivotally disposed on opposite sides of the joint body, capable of being externally applied to a clamping position to a loose position for reciprocating clamping, when the clip is When it is in the loose position, it moves away from the output port. When the clip is in the clamping position, it moves toward the output port to achieve direct and easy operation and excellent combined effect. By.

The injector 20 has an injection flow passage 21 communicating with the inflation flow passage 11, The input port 12 and the output port 13 have a beading projection 22 facing the output port 13 at a central position of the bottom end of the injector 20.

Referring to FIGS. 1 to 3, the airtight ring 30 is a ring body having a predetermined elasticity. The airtight ring 30 is a rubber ring which is disposed in the inflation flow passage 11 of the joint body 10 and is The top end abuts against the bottom end of the injector 20 and surrounds the outer circumference of the bead projection 22.

Referring to FIGS. 1 to 3, the limiting ring 40 is a circular ring body having an externally threaded portion 41 on its outer peripheral surface to be screwed to the internal threaded portion of the joint body 10 by the externally threaded portion 41. 16, the limiting ring 40 is located in the inflation flow channel 11 of the connector body 10 adjacent to the output port 13, and the limiting ring 40 abuts the bottom end of the airtight ring 30 with its top end, so that The airtight ring 30 and the injector 20 are restrained by the limiting ring 40 and are confined in a predetermined position of the inflation flow passage 11 to prevent the injector 20 from coming off the airtight ring 30. Out of the output port 13 of the joint body 10.

Referring to FIGS. 1 to 3, the clamping assembly 50 is disposed on the joint body 10, and is capable of reciprocating pivotal movement by an external force acting between a clamping position and a releasing position. The clamping assembly 50 has a spring 51, two clips 52 and two pivots 53. The spring 51 penetrates into the through hole 14 of the joint body 10. The two clips 52 can respectively define a sheet shape. a pressing portion 521, a clamping portion 522 connected to one end of the pressing portion 521 at a predetermined angle, and two wing portions 523 connected to opposite sides of the pressing portion 521. The edge of the clamping portion 522 has a clamping groove 524. The two wing portions 523 respectively have a corresponding pivot hole 525 for placing the respective pivot holes 525 on the clips 52 outside the two ends of the pivot hole 15 of the joint body 10 and communicating with each other.

Therefore, the above is a description of the components of the clip-on inflation joint 100 and a method of assembling the same according to a preferred embodiment of the present invention, and then the advantages thereof are as follows:

First, the present invention is not subjected to an external force. As shown in FIG. 3, the clip 52 of the clamping assembly 50 is pushed outward by the elastic force of the spring 51, so that the clip 52 is clamped. At the position, the clip portion 522 of the clip 51 is moved toward the output port 13 of the joint main body 10.

When the nozzle of a tire is to be inflated using the present invention, first, an air tube 92 (which may be an inflator or an air pump, not shown) is connected to the pipe joint 60 (such as Figure 6 shows). Then, the user can move the clamping component 50 from the clamping position to the releasing position (as shown in FIG. 4), that is, the user's hand simultaneously presses the pressing portion 521 of the clamping component 50. The spring portion 51 is compressed by the pressing portion 521, so that the clamping portion 522 of the clip 52 is pivoted with the pivot 53 as an axis and is opened (ie, the clamping portion 522 is away from the output port 13). In this state, the air nozzle 91 is inserted into the inflation flow passage 11 from the output port 13, and the indentation projection 22 of the injector 20 is pressed against the ejector pin of the air nozzle 91. On 911. In this way, the user's hand can be released, and the clip 52 can be moved from the loose position to the clamping position by the elastic force provided by the spring 51, so that the clip 524 of the clip 52 is clamped. On the outer peripheral surface of the gas nozzle 91 (as shown in Fig. 5), the original creation 100 and the gas nozzle 91 are fixed by the clip groove 524 of the clip 522.

In this way, the user can control the gas-filled device to perform gas output from the gas pipe 92, the pipe joint 60, the input port 12, the inflation flow path 11, and the injection flow path 21 from the output port 13 The gas nozzle 92 is output and filled, so that the tire can be inflated by the injection of gas. After the inflation is completed, the clip 52 of the clamping assembly 50 can be moved from the clamping position to the release position, and the creation 100 can be separated from the air nozzle 91 to complete the inflation operation.

Therefore, the present invention can be easily fixedly connected to the gas nozzle 91 in a clamping manner by using the clamping unit 50, and at the same time, the gas nozzle 91 can be turned on to achieve an easier and convenient use.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all of the related art in the art according to the present invention are equivalent to the present invention. The scope of coverage.
