Abstract
The invention relates to an oil injection nozzle. The oil injection nozzle comprises an oil injection nozzle body, an inverted-cone-shaped oil injection head is arranged at the end of the oil injection nozzle body and sequentially connected with a conical section and a cylindrical section, an axial oil channel is arranged at the axial center of the oil injection nozzle body, and the cylindrical section is provided with a radial oil channel communicated with the axial oil channel. Preferably, an annular groove is disposed at the position where the inverted-cone-shaped oil injection head and the conical section are connected. More preferably, the diameter of the radial oil channel is larger than that of the axial oil channel. The oil injection nozzle is simple in structure and convenient to install and maintain. The diameter of the radial oil channel is larger than that of the axial oil channel, so that when gasoline enters the axial oil channel from the radial oil channel, the injection pressure can increase suddenly.
Description
Technical field
The present invention relates to a kind of auto parts machinery, be specifically related to a kind of oil nozzle.
Background technique
The structure of the oil nozzle of prior art is used assemblies such as steel loop, bolt and pipe, complex structure, and difficulty of processing is big.And existing oil nozzle is generally some tiny metallic conduits, need be arranged on cylinder body or other component.Oil nozzle needs professional tool to cause to be not easy to install and maintenance when mounted, and easily coming off during use causes other component impaired.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of simple in structure, oil nozzle of being easy for installation and maintenance is provided.
For achieving the above object, the technical solution used in the present invention is as follows.
A kind of oil nozzle comprises the oil nozzle body, and the end of described oil nozzle body is provided with the inverted cone nozzle tip, and described inverted cone nozzle tip is connected with conical section and cylindrical portion in turn; The axial centre of described oil nozzle body is provided with axial oil circuit, and described cylindrical portion is provided with the radially oil circuit that connects with described axial oil circuit.
Further, the joint of described inverted cone nozzle tip and described conical section is provided with circular groove.
Further, the diameter of described radially oil circuit is greater than the diameter of described axial oil circuit.
The invention has the beneficial effects as follows: oil nozzle of the present invention is simple in structure, be easy for installation and maintenance.Because radially the diameter of oil circuit is greater than the axial diameter of oil circuit, thus gasoline when radially oil circuit enters axial oil circuit, jet pressure can become big suddenly.
Description of drawings
Fig. 1 is the structural representation of oil nozzle of the present invention.
Among the figure, 1-inverted cone nozzle tip, the 2-conical section, the 3-cylindrical portion, the 4-circular groove, 5-is oil circuit radially, the axial oil circuit of 6-.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Oil nozzle of the present invention as shown in Figure 1, comprise the oil nozzle body, the end of oil nozzle body is provided with inverted cone nozzle tip 1, institute's inverted cone nozzle tip 1 is connected with conical section 2 and cylindrical portion 3 in turn, inverted cone nozzle tip 1 is provided with circular groove 4 with the joint of conical section 2, the axial centre of oil nozzle body is provided with axial oil circuit 6, and cylindrical portion 3 is provided with the radially oil circuit 5 that connects with axial oil circuit 6.Radially the diameter of oil circuit 5 is greater than the diameter of axial oil circuit 6.
Because radially the diameter of oil circuit is greater than the axial diameter of oil circuit, thus gasoline when radially oil circuit enters axial oil circuit, jet pressure can become big suddenly.Oil nozzle of the present invention is simple in structure, be easy for installation and maintenance.
The above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
Claims (3)
1. an oil nozzle comprises the oil nozzle body, it is characterized in that, the end of described oil nozzle body is provided with the inverted cone nozzle tip, and described inverted cone nozzle tip is connected with conical section and cylindrical portion in turn; The axial centre of described oil nozzle body is provided with axial oil circuit, and described cylindrical portion is provided with the radially oil circuit that connects with described axial oil circuit.
2. oil nozzle according to claim 1 is characterized in that, the joint of described inverted cone nozzle tip and described conical section is provided with circular groove.
