Description

Technical Field

[0001] This utility model relates to the field of carburetor technology, and in particular to a powerful, high-response carburetor. Background Technology

[0002] A carburetor is a core device in an internal combustion engine (such as a gasoline engine) used to mix fuel and air in a specific ratio to form a combustible mixture. It was once widely used in motorcycles, older cars, small generators, garden machinery, and other equipment, and is a crucial component of the fuel supply system. Its working principle is based on the "Venturi effect": when the engine draws in air, the air flows at high speed through a narrow passage (Venturi tube) within the carburetor. The air pressure within the passage decreases, creating a negative pressure that draws the gasoline stored in the float chamber through the metering orifice. The drawn-out gasoline is atomized and broken up by the high-speed airflow, mixing thoroughly with the air to form a suitable air-fuel mixture (the air-fuel ratio is typically around 14.7:1, suitable for complete combustion). This mixture is then drawn into the cylinder, compressed, ignited, and burned to produce power. The carburetor is powerful and highly responsive.

[0003] Existing high-response carburetors typically have a throttle limit screw on their surface, which is the core component controlling the throttle opening. However, after adjustment, the screw often loosens due to significant vibrations when the vehicle moves on bumpy roads. This causes the screw to lose its limiting function on the throttle, resulting in the throttle opening deviating from the preset position and causing an unexpected increase in throttle opening, which affects normal operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the throttle limit screw loosens due to vibration after adjustment, causing it to lose its limiting function on the throttle, resulting in the throttle opening deviating from the preset position and an unexpected increase in throttle opening, thus affecting normal operation. Therefore, this invention proposes a powerful high-response carburetor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powerful high-response carburetor, comprising a carburetor body, a fuel inlet pipe installed on the surface of the carburetor body, a throttle valve mechanism provided on the inner wall of the carburetor body, an air inlet provided on one side of the carburetor body, and a limit device provided on the surface of the carburetor body. The limiting device includes a hollow sleeve fixed to the surface of the carburetor body. A limiting post is slidably connected to the inner wall of the hollow sleeve to limit the opening and closing degree of the throttle mechanism. A threaded rod is rotatably connected to the inner wall of the hollow sleeve, and the threaded rod is threadedly connected to the inner wall of the limiting post. A control shaft is rotatably connected to the inner wall of the hollow sleeve. A transmission assembly is provided between the control shaft and the threaded rod for transmission. A limiting assembly is provided on the surface of the control shaft to limit the rotation of the control shaft. Through the above components, in use, the control shaft can first cooperate with the transmission assembly to control the rotation of the threaded rod, thereby controlling the sliding of the limiting post in the hollow sleeve. The position of the limiting post corresponds to the degree of throttle opening and closing. At the same time, the limiting assembly can further improve the stability effect.

[0006] Preferably, the transmission assembly includes a worm fixed to the surface of the control shaft, an extension shaft fixedly connected to the upper end of the threaded rod, a worm wheel fixedly connected to the surface of the extension shaft, and the worm meshing with the worm wheel. Through the above components, when the control shaft rotates, it can drive the worm to rotate, and the worm, in conjunction with the worm wheel, can drive the extension shaft and the threaded rod to rotate, thereby realizing the transmission operation.

[0007] Preferably, the limiting assembly includes a slide column slidably connected to the inner wall of the control shaft. One end of the slide column is fixedly connected to a limiting head. An extension sleeve is fixedly connected to the surface of the hollow sleeve. A limiting ring is fixedly connected to the inner wall of the extension sleeve. The surface of the limiting ring has multiple limiting grooves. The limiting head is inserted into the inner wall of the limiting groove. A spring is fixedly connected to the side of the slide column corresponding to the inner wall of the control shaft. A control groove is formed on the surface of the limiting head. Through the above components, a tool can be inserted into the control groove, and then the slide column can be pushed to move, causing the limiting head to move out of the limiting groove in the limiting ring. Then, the tool is rotated to drive the control shaft to rotate. When the spring drives the limiting head to reset and insert into the limiting groove on the surface of the limiting ring, the limiting operation can be realized.

[0008] Preferably, the control slot is arranged in a cross shape.

[0009] Preferably, the limiting head is composed of a ring and four locking blocks fixed on the surface of the ring.

[0010] Preferably, the surface of the extension sleeve is provided with an auxiliary component, the auxiliary component including a protective sleeve fitted on the surface of the extension sleeve, a connecting strap fixedly connected to the surface of the protective sleeve, and the other end of the connecting strap fixedly connected to the surface of the hollow sleeve. Through the above components, and by the protective sleeve fitted on the extension sleeve, the area of ​​the limiting component can be shielded and protected.

[0011] Preferably, the inner wall of the protective sleeve is fixedly connected with multiple sets of rubber rings, and the surface of the extension sleeve is fixedly connected with two convex rings. Through the above components, after the protective sleeve is inserted into the extension sleeve, the convex rings can block the rubber rings, thereby improving the overall stability.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a limiting device, and through the cooperation of the control shaft, transmission components, and threaded rod, the sliding position of the limiting post in the hollow sleeve can be precisely controlled, thereby accurately limiting the opening and closing degree of the throttle mechanism. At the same time, the limiting component can improve the stability of the control shaft after adjustment, reduce the loosening phenomenon of traditional screw adjustment, accurately adjust the intake air volume, and ensure that the engine can obtain the best air-fuel mixture concentration under various operating conditions, further enhancing the function.

[0013] In this invention, by setting an auxiliary component, the protective sleeve is fitted into the extension sleeve, and the rubber ring, together with the convex ring, can achieve a limiting position, thereby effectively shielding and protecting the area of ​​the limiting component.

After moving to a certain position, the limit head 511 moves out of the limit groove on the surface of the limit ring 58. Then, the tool drives the limit head 511, slide column 59, and control shaft 54 ​​to rotate. When the control shaft 54 ​​rotates, it drives the worm gear 55 to rotate. The worm gear 55 cooperates with... The worm gear 56 can drive the extension shaft 57 and the threaded rod 53 to rotate, realizing the transmission operation. The threaded rod 53 controls the sliding of the limit post 52 in the hollow sleeve 51. The position of the limit post 52 corresponds to the degree of throttle opening and closing. After the adjustment is completed, the spring 510 drives the sliding post 59 and the limit head 511 to reset.
