Description

Technical Field

[0001] The utility model relates to the technical field of carburetors, and particularly relates to a carburetor with anti-interference adjustment. Background Art

[0002] Adjusting screws are provided on a general carburetor. The adjusting screws include a high-speed adjusting screw and an idle-speed adjusting screw, which are used to adjust the high-speed fuel supply amount and the idle-speed or low-speed fuel supply amount of the carburetor. Generally, the high-speed adjusting screw and the idle-speed adjusting screw are both exposed outside the carburetor. However, since the carburetor is installed near the engine, various pipelines, wires, and devices are densely arranged, resulting in interference. Therefore, if it is necessary to adjust the high-speed adjusting screw and the idle-speed adjusting screw, it is difficult for the adjusting screwdriver to reach in for adjustment, resulting in difficult adjustment. Or it can only be adjusted by disassembling the machine, which will also interfere with other components, and it is very inconvenient. Summary of the Utility Model

The flexible transmission shaft includes a free end and a connecting end, and the adjusting head 42 is connected to the free end of the flexible transmission shaft. The connectors 41 of the two regulators 4 are respectively connected to the corresponding bodies 1 of the high-speed adjusting screw 2 and the idle-speed adjusting screw 3. The connecting ends of the flexible transmission shafts of the two regulators 4 are respectively drivingly connected to the high-speed adjusting screw 2 and the idle-speed adjusting screw 3.

[0024] As can be seen from the above description, by providing the regulator 4, the flexible transmission shaft can extend to the high-speed adjusting screw 2 and the idle-speed adjusting screw 3 respectively, and can be transmitted to the high-speed adjusting screw 2 and the idle-speed adjusting screw 3 by screwing the adjusting head 42 through the flexible transmission shaft from various angles and directions, thereby meeting the adjustment requirements. At the same time, it can prevent interference from other components or interfere with other components, reduce the design difficulty of the engine part, and ensure the convenience of adjustment.

[0025] Further, the regulator 4 further includes a flexible outer sleeve 43. The flexible outer sleeve 43 is sleeved on the flexible transmission shaft and connected to the connector 41. The flexible transmission shaft can rotate relative to the flexible outer sleeve 43.

[0026] As can be seen from the above description, through the flexible sleeve, the flexible transmission shaft can be protected to avoid rust or breakage.

[0027] Further, the flexible outer sleeve 43 is made of rubber material.

[0028] Further, the regulator 4 further includes a binding band, and the binding band is connected to the flexible outer sleeve 43.

[0029] As can be seen from the above description, through the setting of the binding band, the fixing of the regulator 4 can be facilitated, and it can be prevented from swinging randomly during the movement of the vehicle.

[0030] Further, a reinforcing sleeve 44 is provided at the connection between the connector 41 and the flexible outer sleeve 43.

[0031] As can be seen from the above description, through the reinforcing sleeve 44, the direct friction between the flexible outer sleeve 43 and the connector 41 is prevented, thereby preventing the connection from being quickly worn and broken.

[0032] Further, the two regulators 4 are different in color or size.

[0033] As can be seen from the above description, through the regulators 4 with different colors and sizes, the adjustment relationship between the high-speed adjusting screw 2 and the idle-speed adjusting screw 3 can be conveniently and quickly distinguished.

[0034] Further, the adjusting head 42 is a flat groove 45, a cross groove, or a plum blossom hand-tightening type.

[0035] As can be seen from the above description, through the slotted groove 45, cross groove or plum blossom hand-twisting, it can be directly adjusted with a slotted screwdriver, cross screwdriver or directly by hand. The structure is simple and the adjustment is convenient.

[0036] Furthermore, the connector 41 and the body 1 are fixed by screws 5.

[0037] Furthermore, the connector 41 and the body 1 are in threaded fit 6.

[0038] Furthermore, a washer 7 is provided between the connector 41 and the body 1.

[0039] As can be seen from the above description, through the setting of the washer 7, the sealing performance can be improved and the looseness at the connection can be avoided. Embodiment 1
