[0002] An oil cooler is a heat exchange device used to cool lubricating oil or hydraulic oil. It is usually composed of a series of pipes, fins and a shell. When working, hot oil passes through the pipes, and the surrounding air or coolant (such as water) takes away the heat in the oil, thereby reducing the oil temperature.

[0003] Oil coolers are used in many fields, such as automobile engines, industrial machinery, transformers, etc. In automobiles, they help maintain the appropriate temperature of the engine lubricating oil, ensure the normal operation of the engine and extend its service life; in the industrial field, they can cool the hydraulic system and lubrication system of various equipment to ensure stable operation of the equipment.

[0004] When the existing oil cooler pipeline is connected to another set of pipelines, the two sets of pipelines are connected by a flange. During the connection, the flange needs to be manually supported and aligned to fix the flange, so as to achieve the purpose of pipeline connection. However, it is difficult to ensure that the position of the flange is always accurate and stable, which affects the accuracy and sealing of the connection. To address this problem, we propose an oil cooler pipeline connection structure. Utility Model Content

[0026] As Figures 1 - 6 shown, the utility model provides a technical solution: an oil cooler pipeline connection structure, including an oil cooler 1 and a connecting pipe 6.

[0027] A round rod 72 is fixedly installed on the surface of the clamping block 71. The round rod 72 penetrates through the fixing plate 4 and is rotatably connected to the fixing plate 4. The round rod 72 penetrates through the positioning block 5 and is rotatably connected to the positioning block 5. A flat plate 74 is fixedly installed on the inner wall of the positioning block 5. The surface of the flat plate 74 is rotatably connected to the gear 73. The gear 73 is penetrated by the round rod 72 and is fixedly connected to the round rod 72. A vertical rod 76 penetrates through the flat plate 74 and is slidably connected to the flat plate 74. A rack 75 is fixedly installed on the surface of the vertical rod 76. The rack 75 meshes with the gear 73. A rotating part 77 for rotating the round rod 72 is arranged in the positioning block 5. When the pressing rod 773 is pressed into the positioning block 5, the connecting plate 771 fixed on the surface of the pressing rod 773 can move horizontally in the positioning block 5 under the support of the spring 772. When the connecting plate 771 moves, the vertical rod 76 fixed on the surface of the connecting plate 771 can drive the rack 75 to slide on the surface of the gear 73. The gear 73 is stressed to drive the round rod 72 to perform a circular motion on the surface of the flat plate 74. When the round rod 72 rotates, the clamping block 71 fixed on the surface of the round rod 72 forms an interlaced state with the horizontal hole 10 after rotation. This method can initially fix the output pipe 2 and the connecting pipe 6 during connection, and can keep the position of the flange on the pipeline surface accurate and stable all the time, thereby avoiding affecting the connection accuracy and sealing performance.

[0028] The rotating member 77 includes: a connecting plate 771, the surface of the connecting plate 771 is fixedly connected to the surface of the vertical rod 76. When the connecting plate 771 moves, the vertical rod 76 can move stably within the flat plate 74. The surface of the connecting plate 771 is fixedly connected to one end of a spring 772, and the other end of the spring 772 is fixedly installed on the inner wall of the positioning block 5. A pressing rod 773 is fixedly installed on the surface of the connecting plate 771. The pressing rod 773 penetrates through the positioning block 5 and is slidably connected to the positioning block 5. When the pressing rod 773 presses the connecting plate 771, the connecting plate 771 can slide under the support of the spring 772. A connecting rod 774 is fixedly installed on the surface of the connecting plate 771. The surface of the connecting rod 774 is hinged to a limiting rod 775. One side of the limiting rod 775 is fixedly connected to a torsion spring 776, and the other side of the torsion spring 776 is fixedly installed on the surface of the connecting rod 774. A limiting block 777 is fixedly installed on the surface of the connecting rod 774. When the limiting rod 775 is resisted, it can be folded on the surface of the connecting rod 774 under the support of the torsion spring 776. The top of the limiting rod 775 is arc-shaped. When the limiting rod 775 with an arc-shaped top is resisted, it can be folded stably. The driven assembly 8 includes: a cylinder 81, the cylinder 81 is rotatably connected to the inner wall of the positioning block 5. An arc groove 82 is formed inside the cylinder 81. A support hole 83 is formed on the surface of the cylinder 81. When the support hole 83 and the limiting rod 775 are staggered, the connecting rod 774 cannot be removed from the cylinder 81. A rotating rod 84 is fixedly installed on the surface of the cylinder 81. The rotating rod 84 penetrates through the positioning block 5 and is rotatably connected to the positioning block 5. One end of a scroll spring 86 is fixedly connected to the surface of the positioning block 5, and the other end of the scroll spring 86 is fixedly installed on the surface of the rotating rod 84. A turntable 85 is fixedly installed on the surface of the rotating rod 84. When the turntable 85 rotates, the rotating rod 84 can drive the cylinder 81 to perform a circular motion within the positioning block 5.

[0029] In the present utility model, during use, when it is necessary to connect the connecting pipe 6 to the output pipe 2 on the surface of the oil cooler 1, the support plate 9 fixed on the surface of the connecting pipe 6 is fitted with the clamping block 71. The clamping block 71 passes through the transverse hole 10 and is parallel to the transverse hole 10, so that the connecting pipe 6 and the flange on the surface of the output pipe 2 are initially positioned. After positioning, the pressing rod 773 is pressed into the positioning block 5. The connecting plate 771 fixed on the surface of the pressing rod 773 can move horizontally in the positioning block 5 under the support of the spring 772. When the connecting plate 771 moves, the vertical rod 76 fixed on the surface of the connecting plate 771 can drive the rack 75 to slide on the surface of the gear 73. The gear 73 is stressed to drive the round rod 72 to perform a circular motion on the surface of the flat plate 74. When the round rod 72 rotates, the clamping block 71 fixed on the surface of the round rod 72, after rotation, forms an interlaced state with the transverse hole 10. This method can initially fix the output pipe 2 and the connecting pipe 6 during connection, and this method can keep the position of the flange on the pipe surface always accurate and stable, thus avoiding affecting the connection accuracy and sealing performance. At the same time, when the connecting plate 771 moves, the connecting rod 774 enters the cylinder 81. When the support hole 83 opened on the surface of the cylinder 81 touches the limiting rod 775, the limiting rod 775 is stressed and enters the arc groove 82 in the cylinder 81 from the support hole 83 under the support of the torsion spring 776. When the limiting rod 775 is no longer touched, the limiting rod 775 bounces up under the support of the torsion spring 776 to complete the initial fixation. Then the operator can connect the flange on the pipe surface and can avoid the situation of deviation. When it is necessary to separate the output pipe 2 and the connecting pipe 6, the bolts on the flange surface are removed. After removal, the turntable 85 is rotated on the surface of the positioning block 5. Then the rotating rod 84 fixed on the surface of the turntable 85 can drive the cylinder 81 to rotate synchronously. After the support hole 83 opened on the surface of the cylinder 81 rotates, it will be parallel to the limiting rod 775, so that the cylinder 81 can release the fixation of the connecting rod 774. The connecting plate 771 bounces up under the support of the spring 772, and then the clamping block 71 will be parallel to the transverse hole 10 again, so that the output pipe 2 and the connecting pipe 6 can be separated.

[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and concept of the present utility model are all within the protection scope of the present utility model.
