Description

TECHNICAL FIELD

[0001] The utility model relates to a structure of automatic insertion locking quick connector, especially to a combination of male connector, female connector and sleeve, and the female connector is provided with a swing body and an elastic device to achieve labor-saving operation and automatic locking. BACKGROUND

[0002] Fluid pipe lines for cooling fluid of liquid cooling system or water circulation system applied to electric machines or electronic devices (such as computers or servers) are well known in the art. In practice, fluid couplings or quick connectors are used to connect the fluid pipe lines. For example, a patent application for a pipe connector provides a typical embodiment.

[0003] The embodiment includes a combination of a sleeve and a spigot. The sleeve is provided with a channel and a steel ball moving in the channel, and the sleeve is provided with a first valve element. The spigot is provided with a second valve element. The sleeve is combined with a bushing, and an elastic member is arranged between the sleeve and the bushing. When the spigot is inserted into the sleeve along the axial direction, the operator must first push the sleeve forward and pull the bushing outward or backward to make the steel ball free and allow the spigot to be inserted into the sleeve to complete the connection of the spigot and the sleeve.

[0004] One problem related to the structure and operation of the fluid (quick) connector is that the operator must push the sleeve forward and pull the bushing backward, which is opposite (or contradictory) to the force direction of the operator's operation or action. This not only makes the operation inconvenient (or troublesome), but also does not conform to the ergonomics. This is not what we expect.

[0005] Representatively, these references show the use and structure design of the existing fluid quick connector or its related combination components. If the structure of the fluid quick connector is redesigned and the application is considered, it will be different from the prior art, which will change its use form, increase its application effect, and be different from the prior art. For example, under the condition of considering the structure and operation convenience, a connector structure is provided to obtain quick and stable connection (or automatic locking) and / or disconnection (or unlocking) action. And, the operation is labor-saving, which improves the operation connection or (must overcome the weight of the steel ball laterally (component force) to push the steel ball upward) disconnection operation of the existing component, which is more troublesome, does not conform to the ergonomics or the unlocking operation is not smooth.

[0006] These problems are not taught or specifically disclosed in the above-mentioned references. UTILITY MODEL CONTENT

[0007] The utility model discloses a main purpose is to provide a kind of automatic insertion locking quick connector, provide a simple operation, labor-saving and automatic locking (or lock connection) and so on effect. Including the combination of male connector, female connector and sleeve;Male connector defines chamber, the combination end at the both ends area of chamber and the pivot end away from the combination end. Female connector defines sub-chamber, the sub-combination end at the both ends area of sub-chamber and the sub-pivot end away from the sub-combination end. And, female connector combination sleeve can move in axial direction, swing body and elastic device are arranged between sleeve and female connector;Without the effect of pulling sleeve, when operating male connector to connect female connector, swing body (swing movement is generated) can be forced to push elastic device, and automatic connection (or automatic locking (or buckling)) operation is completed;And / or after operating sleeve to move and push swing body, elastic device, the above-mentioned connection operation is released, improve the operation connection and / or release connection operation in prior art, it is more troublesome, not in line with ergonomics or unlocking operation is not smooth and so on situation.

[0008] According to the automatic insertion locking quick connector of the utility model, the female connector is provided with a blocking portion between the sub-combination end and the sub-pivot end. The sleeve defines a first end and a second end away from the first end. The first end of the sleeve is bent to form a space capable of accommodating at least a partial region of the swing body in the internal direction and the second end direction. A linkage member is arranged between the female connector and the sleeve (or the swing body and the elastic device). Therefore, when the male connector is connected to the female connector, the swing body pushes the linkage member and the elastic device, so that the automatic connection operation (or the locking operation) can be completed without pulling the sleeve. When the sleeve is operated to move, the swing body is forced to move away from the male connector and push the linkage member and the elastic device, so that the above-mentioned connection operation (or the unlocking operation) can be released (simultaneously).

[0074] 1. The convex structure 14 (or the inclined surface 15) of the male connector 10 pushes the main end 61 of the swing body 60, and the sub-end 62 is the (virtual) fulcrum, so that the swing body 60 (or the main end 61) swings (towards the upper direction in the figure or the direction of the sleeve 30) and pushes the link member 65 and the elastic member 70 (compresses or accumulates energy), until the swing body 60 (or the main end 61) passes through the flat surface 16.

[0075] 2. The combination end 12 of the male connector 10 pushes the sub-piston 45 to move towards the left direction in the figure, so that the shoulder portion 49 pushes the sub-spring 46 (with the head region 53 of the plunger 50 as the support point) to compress or accumulate energy.
