Description

Quick plug injector mounting bracket

technical field

The utility model relates to a component of an electric jet motorcycle, in particular to a fast plug-in fuel injector mounting bracket of the electric jet motorcycle.

Background technique

The fuel injector is an important part of the EFI motorcycle, which atomizes the fuel at a certain pressure and sprays it into the intake pipe. At present, the fuel injector is usually installed on the engine intake pipe with a sleeve-type bracket, and the inlet of the fuel injector and the sleeve-type bracket, as well as between the sleeve-type bracket and the oil pipe, are directly inserted and fixed with a clamp , the assembly process is more complicated, the assembly efficiency is low, and the inspection and maintenance of the oil circuit is inconvenient. In addition, the socket-type bracket is a metal stamping part, which not only has high material cost, but also has difficulty in ensuring versatility and production consistency, and must be galvanized for anti-rust treatment, which increases the process and production costs. After the socket bracket is galvanized, the smoothness of the inner wall is poor. On the one hand, it will form a large installation resistance, which will affect the speed of assembly; The gap, resulting in oil seepage, leakage and so on.

Utility model content

The technical problem to be solved by the utility model is to provide a quick-insert bracket that can facilitate the installation of the fuel injector.

The technical scheme of the utility model is as follows: a fast plug-in fuel injector mounting bracket, which is composed of a sleeve, a positioning tube and a lug, wherein the mouth of the sleeve faces downward, and the bottom of the sleeve is connected to the lower end of the positioning tube , the central hole of the positioning tube communicates with the inner cavity of the sleeve, and an annular boss is provided on the outer wall of the lower part of the positioning tube; a lug is provided on the outer wall of the sleeve, and a circular lug is opened on the lug Via.

Using the above technical scheme, the sleeve is set on the inlet of the fuel injector, the bolt passes through the circular hole on the lug, and the utility model is fixed on the engine intake pipe, and the positioning pipe is inserted into the quick plug of the oil pipe, and the lower part of the positioning pipe The ring-shaped boss of the valve acts as a positioning function to prevent the positioning tube from withdrawing from the quick plug. It can be seen that the utility model can facilitate the installation of the fuel injector, not only the assembly process is simple, the assembly efficiency is high, but also the disassembly and assembly are easy, and the inspection and maintenance of the oil circuit is convenient.

The sleeve, the positioning tube and the lug are integrally formed by injection molding of nylon. In this way, on the one hand, the processing is easy, the cost is low, the versatility and the production consistency are good; on the other hand, the smoothness of the inner and outer surfaces is good, and the installation resistance is small, which further improves the assembly speed and can effectively prevent oil leakage and leakage. And so on.

In order to conveniently fit the sleeve on the inlet of the fuel injector, the mouth of the sleeve is trumpet-shaped.

An annular groove is arranged on the outer wall of the lower part of the sleeve, and the annular groove is located below the lug. The ring groove is used for clamp installation, so that after the sleeve is set at the inlet of the fuel injector, it is fixed by the clamp, which enhances the reliability of the connection between the sleeve and the fuel injector.

Beneficial effects: the utility model has the characteristics of ingenious design, easy processing, low cost, versatility and good production consistency, and can facilitate the installation of the fuel injector. It is convenient for inspection and maintenance, and effectively eliminates oil seepage and leakage.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figures 1 and 2, the utility model is composed of a sleeve 1, a positioning tube 2 and a lug 3, and the sleeve 1, the positioning tube 2 and the lug 3 are integrally formed by injection molding of nylon. The mouth of the sleeve 1 faces downwards, and the mouth of the sleeve 1 is trumpet-shaped, which acts as a guide, so that the sleeve 1 is fitted on the inlet of the fuel injector 4 . There is a ring groove 1a on the outer wall of the lower part of the sleeve 1, and the ring groove 1a is used for clamp installation, so that after the sleeve 1 is set on the inlet of the fuel injector 4, it is fixed by a clamp to make the connection between the sleeve and the fuel injector The connection between them is firm to avoid falling off. The bottom of the sleeve 1 is connected to the lower end of the positioning tube 2, the axis of the positioning tube 2 is on the same line as the axis of the sleeve 1, the central hole of the positioning tube 2 communicates with the inner cavity of the sleeve 1, and the positioning tube 2 An annular boss 2a is integrally formed on the outer wall of the lower part. The positioning pipe 2 is inserted into the oil pipe quick plug 5, and the oil pipe quick plug 5 is connected with the oil pump through the oil pipe. The annular boss 2a at the bottom of the positioning tube 2 plays a positioning role to prevent the positioning tube 2 from withdrawing from the quick plug 5 .

As can be seen from FIG. 1 , a lug 3 is integrally formed on the outer wall of the sleeve 1 , the lug 3 is located above the ring groove 1 a, and a circular through hole 3 a is opened on the lug 3 . The bolt passes through the circular through hole 3a on the lug 3, and the utility model is fixed on the engine intake pipe.
