Description

Technical Field

[0001] This utility model relates to the field of anti-overflow connector technology, specifically to an anti-overflow connector for a lubricating oil delivery pipeline. Background Technology

[0002] The publication (announcement) number is CN103267189A, the publication (announcement) date is 2013-08-28, and the name is "Anti-overflow Water Pressure Boosting Connector". It includes a connector body with an inlet and outlet water channel within it. The connector body also has a pressure boosting channel that connects the inlet and outlet water channels. An anti-overflow device connected to the pressure boosting channel and capable of injecting air is provided on the connector body. This connector can enhance the water pressure during the use of faucets, shower heads, spray guns, shower hoses, and other products, thereby achieving water conservation and environmental protection while increasing water flow, allowing bathroom products to reach their optimal performance limits. It can also provide high-pressure, high-flow showering even in areas with insufficient water pressure.

[0003] In the aforementioned patent process, air is injected into the interface to make the pressure inside the connector greater than that of hydraulic pressure, thereby preventing overflow. However, it requires an external air injection device and an air discharge device, and the pressure inside the connector may be greater than atmospheric pressure. Long-term operation may lead to a difference in air pressure inside and outside the connector, resulting in cracking of the connector. Utility Model Content

[0004] The purpose of this invention is to provide an anti-overflow connector for lubricating oil delivery pipelines to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-overflow connector for a lubricating oil delivery pipeline includes a housing with a liquid inlet connected through it. A buoyancy member is slidably connected inside the housing. The buoyancy member has a position for closing the liquid inlet and a position for opening the closure. When the liquid level inside the housing reaches a preset position, the buoyancy member seals the liquid inlet.

[0007] Three mounting seats are fixedly connected around the inner wall of the housing near the liquid inlet. Each mounting seat has a plug-in block slidably connected inside it, and each plug-in block is connected to its corresponding mounting seat by a spring.

[0008] Each of the plug blocks has a transmission pin fixedly connected to its opposite sides, and each of the mounting bases has a first waist-shaped groove that matches the position of each transmission pin.

[0009] A lifting seat is slidably connected to the axial direction of the housing. Each lifting seat has a second waist-shaped groove corresponding to the position of the first waist-shaped groove. Each transmission pin is located in the first waist-shaped groove and the second waist-shaped groove respectively.

[0010] Each buoyancy component has a matching insertion slot at the radial position corresponding to the position of each insertion block.

[0011] In the above technical solution, the present invention provides a lubricating oil delivery pipeline anti-overflow joint, which causes the buoyancy component to move upward as the liquid level rises, thereby sealing the liquid inlet.

[0012] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0022] Reference Figure 1-4 As shown, this utility model provides an anti-overflow connector for a lubricating oil delivery pipeline, including a housing 1, with a liquid inlet 1.01 connected through the housing 1, and a buoyancy member 1.1 slidably connected inside the housing 1. The buoyancy member 1.1 has a position for closing the liquid inlet 1.01 and a position for opening the closure. When the liquid level inside the housing 1 reaches the preset position, the buoyancy member 1.1 seals the liquid inlet 1.01.

[0023] Among them, three mounting seats 1.2 are fixedly connected around the inner wall of the housing 1 near the liquid inlet 1.01. Each mounting seat 1.2 has a plug block 1.3 slidably connected inside it. Each plug block 1.3 is connected to its corresponding mounting seat 1.2 by a spring 1.4.

[0024] Each plug block 1.3 has a transmission pin 1.30 fixedly connected to its opposite sides, and each mounting base 1.2 has a first waist-shaped groove that matches the position of each transmission pin 1.30.

[0025] A lifting seat 1.5 is slidably connected to the housing 1 in the axial direction. Each lifting seat 1.5 has a second waist-shaped groove 1.50 corresponding to the position of the first waist-shaped groove 1.20. Each transmission pin 1.30 is located in the first waist-shaped groove 1.20 and the second waist-shaped groove 1.50 respectively.

[0026] Each buoyancy component 1.1 has a matching insertion slot 1.10 at the radial position corresponding to each insertion block 1.3.

[0027] Specifically, a liquid inlet 1.01 is connected to the upper end of the housing 1, and a liquid outlet 1.02 is connected to the bottom end of the housing 1. A buoyancy member 1.1 is slidably connected to the inner wall of the housing 1. The buoyancy member 1.1 has a position for closing the liquid inlet 1.01 and a position for opening and closing. Three mounting seats 1.2 are fixedly connected around the inner wall of the housing 1 near the liquid inlet 1.01. Each mounting seat 1.2 has a first waist-shaped groove 1.20 on its opposite sides. A plug-in block 1.3 is slidably connected in each mounting seat 1.2. A transmission pin 1.30 that matches the first waist-shaped groove 1.20 is fixedly connected to the opposite side walls of the plug-in block 1.3. The plug-in block 1.3 and its corresponding mounting seat 1.2 are fixedly connected by a spring 1.4. A lifting seat 1.5 is coaxially sleeved inside the housing 1. The lifting seat 1.5 slides in the axial direction of the housing 1. A second waist-shaped groove 1.50 is opened on the lifting seat 1.5 at the position corresponding to each plug block 1.3. Each transmission pin 1.30 on the plug block 1.3 corresponds to the first waist-shaped groove 1.20 and the second waist-shaped groove 1.50. A matching plug groove 1.10 is opened on the radial direction of the buoyancy member 1.1 at the position corresponding to each plug block 1.3. A matching plug groove 1.10 is opened on the radial direction of the buoyancy member 1.1 at the position corresponding to each plug block 1.3. Three plug posts 1.11 are fixedly connected around the buoyancy member 1.1. A corresponding plug hole 1.51 is opened on the lifting seat 1.5 at the position corresponding to each plug post.

[0028] In use, when the user introduces liquid into the inlet 1.01, the buoyancy component 1.1 disengages from the inlet 1.01 under hydraulic pressure. When the liquid level inside the housing 1 rises, the buoyancy component 1.1 moves upward with the liquid level. When the buoyancy component 1.1 abuts against the lifting seat 1.5, the lifting seat 1.5 moves upward, thereby compressing the spring 1.4 of the plug-in block 1.3 until each plug-in slot 1.10 corresponds to the plug-in block 1.3. This locks and limits the buoyancy component 1.1 within the plug-in slot 1.10 of the plug-in block 1.3, thus blocking the inlet 1.01.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
