Description

Technical Field

[0001] This application relates to the field of Venturi diluter technology, specifically a Venturi diluter water gun quick connector. Background Technology

[0002] The working principle of a Venturi diluter is primarily based on the Venturi effect, a physical phenomenon where the flow velocity increases as fluid passes through a gradually narrowing channel, creating negative pressure that draws in or mixes with other fluids. Specifically, a Venturi diluter utilizes the negative pressure generated by a high-speed fluid flow to draw in or mix with another fluid, achieving dilution. This type of device is commonly used in applications requiring precise control of fluid mixing ratios, such as chemical processing and environmental engineering.

[0003] Venturi diluters are typically equipped with hose connectors at the outlet end for hose connection and to use the hose's elasticity to tighten the connector, thus completing the hose installation. However, under certain high-pressure conditions, especially when the other end of the hose is connected to a high-pressure water gun, the hose may expand under high pressure and detach from the Venturi diluter connector, affecting operations and causing losses.

[0004] Therefore, this application provides a quick connector for a Venturi diluter water gun to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a quick connector for a Venturi diluter water gun, which aims to solve the problem mentioned in the background art that existing Venturi diluter quick connectors are prone to hose expansion due to hydraulic pressure in high-pressure scenarios, thereby detaching from the connector, affecting operations and causing losses.

[0006] To achieve the above objectives, this application provides the following technical solution: a quick connector for a Venturi diluter water gun, comprising a Venturi diluter and a tapered hose connector fixedly connected to the outlet end of the Venturi diluter.

[0007] The tapered hose connector is fitted with a threaded ring seat at its root, which is fixedly connected to the Venturi diluter. A locking sleeve, screwed onto the threaded ring seat, is fitted over the threaded ring seat. Inside the locking sleeve, a clamping ring is rotatably mounted to press the hose against the side wall of the tapered hose connector. The inclination of the inner wall of the clamping ring matches the inclination of the outer wall of the tapered hose connector. Two sets of parallel balls are embedded in the inner wall of the locking sleeve, contacting the outer wall of the clamping ring. The outer wall of the clamping ring has two grooves to accommodate the two sets of balls. Thus, the clamping ring and locking sleeve work together to achieve uniform and tight compression of the hose, effectively preventing the hose from expanding and detaching from the connector under high pressure. This connector is suitable for hoses of different diameters; adaptation can be achieved simply by adjusting the tightness of the locking sleeve.

[0008] Preferably, the inner wall of the locking sleeve near the tapered hose connector has a nut thread that matches the threaded ring seat.

[0009] Preferably, the end of the locking sleeve away from the tapered hose connector has a dustproof plate covering the end of the hoop.

[0010] Preferably, the inner surface of the hoop ring has a rubber pad for contacting the hose connection end.

[0011] Preferably, the outer wall of the locking sleeve has a plurality of friction patterns distributed in a ring array.

[0012] Preferably, a flange is fixedly connected to the outer wall of the locking sleeve near the tapered hose connector, and a pin for locking the locking sleeve onto the Venturi diluter is screwed onto the flange.

[0013] Preferably, the outlet end of the tapered hose connector has a plurality of pin holes arranged in a ring array for the insertion of the pin rod.

[0014] This Venturi diluter water gun quick connector uses a clamp and locking sleeve to achieve uniform and tight compression of the hose, effectively preventing the hose from expanding and detaching from the connector under high pressure. This connector is suitable for hoses of different diameters; simply adjust the tightness of the locking sleeve to achieve a fit.

[0015] This Venturi diluter water gun quick connector, through the addition of flanges and pins, effectively prevents the locking sleeve from loosening and dislodging from the threaded ring seat under vibration, thus improving the stability and reliability of the connector.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 This embodiment provides a quick-connect head for a Venturi diluter water gun, such as... Figures 1-4 As shown, the Venturi diluter water gun quick connector includes a Venturi diluter 1 and a tapered hose connector 11 fixedly connected to the outlet end of the Venturi diluter 1.

[0020] The tapered hose connector 11 is fitted with a threaded ring seat 12 that is fixedly connected to the Venturi diluter 1. The threaded ring seat 12 is fitted with a locking sleeve 2 that is screwed onto the threaded ring seat 12. A clamping ring 3 is rotatably installed inside the locking sleeve 2 to press the hose on the side wall of the tapered hose connector 11. The inclination of the inner wall of the clamping ring 3 is consistent with the inclination of the outer wall of the tapered hose connector 11. Two sets of balls 4 arranged in parallel and in contact with the outer wall of the clamping ring 3 are embedded in the inner wall of the locking sleeve 2. Two grooves 31 are opened on the outer wall of the clamping ring 3 to accommodate the two sets of balls 4.

[0021] In use, pass the hose connection end through the end of the locking sleeve 2 away from the tapered hose connector 11 and fit it onto the tapered hose connector 11. Then align the locking sleeve 2 with the threaded ring seat 12 and rotate the locking sleeve 2 so that it moves along the threaded ring seat 12 toward the tapered hose connector 11 until the clamping ring 3 completely presses the hose. Start the Venturi diluter 1 to perform fluid mixing. Under high pressure, the clamping ring 3 ensures that the hose will not expand and detach from the connector. When it is necessary to disconnect, rotate the locking sleeve 2 in the opposite direction so that it moves along the threaded ring seat 12 away from the tapered hose connector 11, and then remove the hose.

[0022] Among them, the inner wall of the locking sleeve 2 near the tapered hose connector 11 has a nut thread 21 that matches the threaded ring seat 12; when the locking sleeve 2 is rotated, it will gradually move forward or backward along the thread of the threaded ring seat 12. This design allows users to adjust the position of the locking sleeve 2 by simple rotation, thereby achieving the tightening or release of the clamping ring 3.

[0023] Furthermore, the end of the locking sleeve 2 away from the tapered hose connector 11 has a dustproof plate 23 covering the end of the hoop 3; the dustproof plate 23 is an annular plate structure fixed to the end of the locking sleeve 2, which covers the end of the hoop 3 to prevent dust, dirt or other impurities from entering the gap between the locking sleeve 2 and the hoop 3.

[0024] Furthermore, the inner surface of the clamp ring 3 has a rubber pad 5 for contacting the hose connection end; when the clamp ring 3 presses against the hose, the rubber pad 5 provides additional sealing and cushioning, reducing the direct pressure of the clamp ring 3 on the hose and lowering the risk of hose damage.

[0025] It should be noted that the outer wall of the lock sleeve 2 has several friction textures 22 distributed in a ring array; this makes it easy for the user to rotate the lock sleeve 2, and can be easily operated even when hands are wet or gloves are worn.

[0026] Example 2 Unlike Example 1, when the Venturi diluter 1 is connected to equipment that may vibrate, the threaded connection is prone to loosening, causing the locking sleeve 2 to disengage from the threaded ring seat 12. Therefore, as follows: Figure 5 As shown, a flange 24 is fixedly connected to the outer wall of the locking sleeve 2 near the tapered hose connector 11. A pin 6 for locking the locking sleeve 2 on the venturi diluter 1 is screwed onto the flange 24. The outlet end of the tapered hose connector 11 has several pin holes 13 arranged in a ring array for the pin 6 to be inserted.

[0027] After the locking sleeve 2 is installed on the threaded ring seat 12, the pin 6 is rotated so that its end is inserted into the aligned pin hole 13, thereby limiting the locking sleeve 2 from rotating due to vibration and preventing it from loosening. By adding the flange 24 and the pin 6, the problem of the locking sleeve 2 loosening and detaching from the threaded ring seat 12 under vibration is effectively prevented, and the stability and reliability of the connector are improved.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
