Abstract
The utility model discloses an oil supply pipe joint of an automobile internal combustion engine. The oil supply pipe joint comprises a connecting pipe with a right angle, seal rings and one-way check valves, wherein the vertical segment of the connecting pipe is communicated with a transfer pump of the internal combustion engine and is sealed through the seal rings; the one-way check valves are respectively arranged inside the vertical segment and the horizontal segment of the connecting pipe; the seal rings are arranged inside a seal groove formed in the outer wall of the connecting pipe and are tightly close to the inner wall of the transfer pump; and the amount of the seal rings is 2-3. The oil supply pipe joint is compact in structure; one-way transferring of oil is reliably ensured through the two one-way check valves; meanwhile, transferring can be carried out on oil supply pipes at different angles and positions through the connecting pipe with the right angle; and the oil supply pipe joint is suitable for changing working environment, is flexible to use, and is good in sealing property during the rotation process.
Description
Technical field
The utility model relates to a kind of oil pipe, is specifically related to a kind of car combustion engine fuel supply line joint.
Background technique
The oil connection of car combustion engine is the joint that the transfer pump of car combustion engine is connected to the fuel supply line of fuel tank, this joint have a bearing that is connected with transfer pump and with the suitable connecting tube of bearing, usually connecting tube is to be fixed on the bearing by latch, so the position of connecting tube is locked in the bearing, not rotatable, this kind means of fixation has limited the working state of oil pipe greatly, simultaneously, if oil pipe is subjected to displacement deviation at work, the sealability of joint can not get guaranteeing, produces oil leakage.
The model utility content
The model utility purpose: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of can different amount work and the car combustion engine fuel supply line joint of good seal performance.
Technological scheme: a kind of car combustion engine fuel supply line of the utility model joint, comprise the connecting tube, seal ring and the one way stop peturn valve that have the right angle, vertical section of described connecting tube communicates with the transfer pump of internal-combustion engine and seals by described seal ring, in vertical section of described connecting tube and horizontal segment a described one way stop peturn valve is set respectively and is used for preventing that fluid from refluxing.
In order to prevent the fluid leakage, described seal ring is arranged in the seal groove of described connecting tube outer wall, near the inwall of transfer pump, improves sealing.
Preferably, the quantity of described seal ring is 2 ~ 3, and the size deviation in the time of can compensating oil connection and be moved guarantees that sealing is reliable.
Further, the outer wall of described connecting tube is provided with shoulder block, and described shoulder block is limited in the opening of transfer pump to the position of described connecting tube, and connecting tube can 360 ° of rotations satisfy the different station needs to be connected with fuel supply line without angle on horizontal plane.
Further, the adapter section outer wall of described connecting tube and transfer pump is screw thread or profile of tooth, and is tightr with the combination of transfer pump, improved sealing.
Beneficial effect: the utility model compact structure, two one way stop peturn valves are set, guaranteed the unidirectional conveying of fluid reliably, simultaneously, the connecting tube that has the right angle can carrying to the fuel supply line of different amount position, be adapted to changeable working environment, use flexibly, and in rotating process favorable sealing property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Embodiment:A kind of car combustion engine fuel supply line joint comprises the connecting tube 1, the seal ring 201 that have the right angle; 202 and one way stop peturn valve 301; 302, vertical section of connecting tube 1 communicates with the transfer pump 4 of internal-combustion engine, and fluid enters 1, two seal ring 201 of connecting tube; 202 are arranged in the seal groove of connecting tube 1 outer wall, inwall near transfer pump 4 seals, connecting tube 1 is screw thread with the adapter section outer wall of transfer pump 4, with transfer pump 4 for being threaded, the enhanced leaktightness performance arranges an one way stop peturn valve 301 respectively in vertical section of connecting tube 1 and horizontal segment; 302 are used for preventing that fluid from refluxing, and the outer wall of connecting tube 1 is provided with shoulder block 5, and shoulder block 5 is limited in the opening of transfer pump 4 to the position of connecting tube 1, and connecting tube 1 can 360 ° of rotations satisfy the different station needs to be connected with fuel supply line without angle on horizontal plane.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
