Abstract

The utility model discloses a joint device for an automobile fuel tank. The joint device comprises a fixed base and a welding elbow, wherein one end of the welding elbow is connected with a cylindrical table, a fixed part is arranged on the cylindrical table, a step is formed between the cylindrical table and the fixed part, the fixed base is clamped on the step and fixed with the cylindrical table through welding, and a sealing groove is formed in the fixed part. According to the joint device, the cylindrical table and the fixed part are sequentially connected to the top end of the welding elbow, and the fixed base is clamped on the step and fixed with the cylindrical table through welding, so that the fixed part is located below the fixed base and can be embedded in a fuel mouth of the fuel tank during installation, and the butt joint with the fuel mouth can be realized more conveniently; the sealing groove is formed in the fixed part and used for installing a sealing ring, so that the improvement on the sealing performance of the joint device after installation is facilitated; and compared with the prior art, the joint device has the advantages that the device is more accurate and convenient to connect and better in sealing performance.

Description

A kind of piecing devices for automotive oil tank
[technical field]
The utility model relates to vehicular spare parts technical field, particularly a kind of piecing devices for automotive oil tank.
[background technology]
In automobile, fuel tank and oil pipe are to carry out the direct of " mouth-to-mouth " by flange and connection pipe with hydraulic fluid port to be connected, connection pipe is connected with oil pipe again, due to the most complicated structures of attachment flange, manufacturing cost is higher, developers have designed a kind of automotive oil tank piecing devices that are made up of the permanent seat with screw and bend pipe, one end of bend pipe is directly welded on permanent seat, the other end of bend pipe is used for being set with oil pipe, permanent seat has been realized after the screw at two ends is connected with fuel tank being connected of oil pipe and fuel tank by being positioned at, in actual use, because permanent seat bottom is planar structure, and non-structure extend in fuel tank, make permanent seat be difficult for aliging with the hydraulic fluid port of fuel tank, when making troubles to installation, in sealing property, be also difficult to meet the demands.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of piecing devices for automotive oil tank, can conveniently realize and the docking of hydraulic fluid port, and improves the leak tightness of oil port, guarantees effective oil suction.
For achieving the above object, the utility model proposes a kind of piecing devices for automotive oil tank, comprise permanent seat and welding bend pipe, one end of described welding bend pipe is connected with cylinder table, on described cylinder table, be provided with fixed part, between described cylinder table and fixed part, be formed with step, described permanent seat is stuck on step and with cylinder table and is welded and fixed, and on described fixed part, offers seal groove.
As preferably, on the other end of described welding bend pipe, be connected with tube socket portion, in described tube socket portion, be radially provided with protruding ring.
As preferably, described welding bend pipe and the junction of tube socket portion are provided with the second protruding ring.
As preferably, on described permanent seat, offer fixed orifice.
The beneficial effects of the utility model: the utility model is by top connecting cylinder platform and the fixed part successively at welding bend pipe, permanent seat is stuck on step and with cylinder table and is welded and fixed, make fixed position in the below of permanent seat, fixed part can be embedded in the hydraulic fluid port of fuel tank when mounted, can more facilitate and realize and the docking of hydraulic fluid port, by offer seal groove on fixed part, be used for installing seal ring, be conducive to improve the leak tightness after the utility model is installed, compared with prior art, the utlity model has connection more accurate, convenient, the advantage of better tightness.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is solid of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: 1-permanent seat, 2-welding bend pipe, 3-cylinder table, 4-fixed part, 5-step, 6-seal groove, 7-tube socket portion, 8-protruding ring, 9-the second protruding ring, 10-fixed orifice.
[specific embodiment]
Consult Fig. 1 and Fig. 2, the utility model comprises permanent seat 1 and welding bend pipe 2, one end of described welding bend pipe 2 is connected with cylinder table 3, on described cylinder table 3, be provided with fixed part 4, between described cylinder table 3 and fixed part 4, be formed with step 5, permanent seat 1 is stuck on step 5 and with described cylinder table 3 and is welded and fixed, on described fixed part 4, offer seal groove 6, on the other end of described welding bend pipe 2, be connected with tube socket portion 7, in described tube socket portion 7, be radially provided with protruding ring 8, described welding bend pipe 2 is provided with the second protruding ring 9 with the junction of tube socket portion 7, on described permanent seat 1, offer fixed orifice 10.
Principle of work of the present utility model: the utility model is by one end connecting cylinder platform 3 at welding bend pipe 2, fixed part 4 is set on cylinder table 3, make to form step 5 between fixed part 4 and cylinder table 3, permanent seat 1 is stuck in rear on step 5 and is welded and fixed with cylinder table 3, thereby make fixed part 4 be positioned at the below of permanent seat 1, fixed part 4 can be embedded in the hydraulic fluid port of fuel tank when mounted, can more facilitate and realize and the docking of hydraulic fluid port, by offer seal groove 6 on fixed part 4, seal groove 6 is for installing seal ring, be conducive to improve the leak tightness after the utility model is installed, guarantee actv. oil suction, the top of welding bend pipe 2 arranges tube socket portion 7, be used for installing oil pipe, in tube socket portion 7, be radially provided with protruding ring 8, protruding ring 8 has reinforcement effect for oil pipe, the second 9 of bulge loops progress has improved the fixing fastness of oil pipe.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
