Description

Technical Field

[0001] The present application relates to the technical field of engine cylinder heads, and in particular to an engine cylinder head that is easy to install. Background Art

[0002] The engine cylinder head is a component installed on the cylinder block, sealing the cylinder from the top to form a combustion chamber. Its main function is to draw air into the cylinder, and the spark plug ignites the combustible mixture, driving the piston to work, and the exhaust gas is discharged from the exhaust pipe.

[0003] Existing engine cylinder heads are all installed by screwing with bolts, which makes the engine cylinder heads inconvenient to disassemble and assemble. Therefore, we propose an engine cylinder head that is easy to install. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide an engine cylinder head that is easy to install, so as to solve the technical problem in the existing technology that the engine cylinder head is difficult to disassemble and assemble.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an engine cylinder head that is easy to install, comprising an engine cylinder block, an engine cylinder head body, fixed blocks fixedly arranged on both sides of the engine cylinder block, and connecting members arranged on both sides of the engine cylinder head body, wherein both sides of the engine cylinder head body are provided with sliding grooves along the height direction of the engine cylinder head body, and the connecting members include a slider connected to the engine cylinder head body by sliding in the sliding groove and a rotating block rotatably connected to the end of the slider away from the sliding groove, a connecting block is laterally extended from the end of the rotating block away from the slider, and a plug interface is provided on the side of the fixed block away from the engine cylinder block.

[0006] By adopting the above technical solution, the engine cylinder head body is placed on the engine cylinder block, so that the slider is aligned with the fixed block, and then the slider is slid downward, and the rotating block is rotated at the same time, so that the connecting block extends into the plug-in interface, thereby fixing the engine cylinder block and the engine cylinder head body together, making the installation of the engine cylinder head body more convenient.

[0007] Furthermore, the left and right sides of the connecting block and the left and right sides inside the plug interface are provided with fixing structures for preventing the connecting block from being separated from the plug interface.

[0008] Furthermore, the fixing structure includes two receiving grooves opened on the left and right sides of the connecting block, two clamping columns respectively inserted into the two receiving grooves, and connecting grooves opened in the fixing block on the left and right sides of the inside of the plug-in interface, and a fixing component for fixing the clamping columns is provided at the opposite ends of the two clamping columns.

[0009] Furthermore, a connection port that passes through the receiving groove is opened at one end of the connecting block close to the rotating block, and the fixing assembly includes two fixing plates respectively fixed on two clamping columns and a threaded column passing through the two fixing plates, the threaded column is threadedly connected to the fixing plate, and the two fixing plates extend out of the connecting block through the connection port, and the threaded column is located outside the connecting block.

[0010] By adopting the above technical solution, although the setting of the connecting piece and the fixing block can make the installation of the engine cylinder head body more convenient, the frequency of vibration of the engine during use is very high, which may cause the connecting block to vibrate and move outside the plug-in interface, causing the connecting block to detach from the plug-in interface. The setting of the fixed structure solves this technical problem. After the connecting block is inserted into the plug-in interface, the two clamping columns are pushed into the connecting groove through the two fixing plates, and then the two fixing plates are supported and the threaded columns are screwed on to fix the positions of the two clamping columns. In this way, the connecting block is confined in the fixing block, thereby improving the stability of the installation of the connecting piece.

[0011] Furthermore, the upper surface of the engine cylinder block and the bottom surface of the engine cylinder head body are provided with a guide structure for facilitating the installation of the engine cylinder head body.

[0012] Furthermore, the guide structure includes a plurality of guide holes opened on the engine cylinder block and a plurality of guide columns fixedly connected to the engine cylinder head body.

[0013] By adopting the above technical solution, although the setting of the connecting parts and the fixing block can make the installation of the engine cylinder head body more convenient, when the staff places the engine cylinder head body on the engine cylinder block, the slider cannot be directly aligned with the fixing block, resulting in the staff needing to adjust when installing the engine cylinder head body and the slider cannot be aligned with the fixing block very accurately during adjustment, which is very inconvenient. The setting of the guide structure solves this technical problem. When placing the engine cylinder head body, the guide column is aligned with the guide hole, and then the engine cylinder head body is placed so that the guide column is inserted into the guide hole, so that the position of the engine cylinder head body is limited, thereby aligning the slider with the fixing block. When adjusting, it is only necessary to swing the engine cylinder head body so that the guide column is inserted into the guide hole, making the installation of the engine cylinder head body more convenient.

[0014] Furthermore, a connecting tension spring is provided in the slide groove, one end of the connecting tension spring is fixed on the top surface of the slide groove and connected to the engine cylinder head body, and the other end is fixedly connected to the slider.

[0015] By adopting the above technical solution, although the setting of the connecting piece makes the installation of the engine cylinder head body more convenient, the engine cylinder head body does not have a top-down force acting on the engine cylinder block, which may cause a gap to appear between the engine cylinder head body and the engine cylinder block. The existing technology fills the gap by placing a sealing oil gasket between the engine cylinder head body and the engine cylinder block, but without this top-down force, the sealing oil gasket cannot be pressed. Although the gravity of the engine cylinder head body itself can provide this force, it is still not enough to press the sealing oil gasket to completely fill the gap. The setting of the connecting tension spring solves this technical problem. By pulling the slider downward and then rotating the rotating block, the connecting block is extended into the plug-in interface. At this time, the tension of the connecting tension spring will act on the engine cylinder block through the connecting piece as a whole, so that the connecting tension spring pulls the engine cylinder head body to press the engine cylinder block, thereby reducing the possibility of a gap between the engine cylinder head body and the engine cylinder block.

[0016] Furthermore, protective structures are provided on the left and right sides of the slide and on the left and right sides of the slider to prevent the slider from leaving the slide. The protective structure includes protective grooves provided on the left and right sides of the slide along the height direction of the slide, and protective blocks fixed on the left and right sides of the slider with one end extending into the protective groove.

[0017] By adopting the above technical solution, the connecting tension spring may break after aging and rusting. The force generated after breaking may cause the slider to be thrown out of the slide groove. The setting of the protective structure prevents this situation from occurring. The protective block extends into the protective groove to limit the slider from leaving the slide groove, but does not affect the up and down sliding of the slider.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The arrangement of the connecting piece, the fixing block and the guide structure makes the installation of the engine cylinder head body more convenient, and the arrangement of the fixing structure and the connecting tension spring makes the installation of the engine cylinder head body more stable.

[0024] The present application is further described in detail below with reference to the accompanying drawings.

[0025] Example, see Figure 1 、 Figure 2 、 Figure 3 The cam 32 is connected to the cam 31 on both sides of the cam 32 so that the cam 32 is inserted into the cam 31 and the cam 32 is inserted into the cam 31, thereby fixing the cam 32 and the cam 32 to the cam 31.

[0026] Although the arrangement of the connecting piece 3 and the fixing block 10 can make the installation of the engine cylinder head body 2 more convenient, the frequency of vibration of the engine during use is very large, which may cause the connecting block 32 to vibrate and move toward the outside of the plug-in interface 11, causing the connecting block 32 to detach from the plug-in interface 11. In order to solve this technical problem, this embodiment provides a fixing structure 4 on the left and right sides of the connecting block 32 and on the left and right sides inside the plug-in interface 11 to prevent the connecting block 32 from detaching from the plug-in interface 11. The fixing structure 4 includes two receiving grooves 40 on the left and right sides of the connecting block 32, two clamping posts 41 respectively inserted into the two receiving grooves 40, and a connecting groove 42 located on the left and right sides of the inside of the plug-in interface 11. The opposite ends of the two clamping posts 41 are provided with a fixing structure for fixing the clamping post. The fixing component 5 of the column 41, the connecting block 32 is provided with a connecting port 33 that passes through the receiving groove 40 at one end near the rotating block 31, the fixing component 5 includes two fixing plates 50 respectively fixed on the two clamping columns 41 and a threaded column 51 passing through the two fixing plates 50, the threaded column 51 is threadedly connected to the fixing plate 50, the two fixing plates 50 extend out of the connecting block 32 through the connecting port 33, the threaded column 51 is located outside the connecting block 32, after the connecting block 32 is extended into the plug-in port 11, the two fixing plates 50 are used to push the two clamping columns 41 into the connecting groove 42, and then the two fixing plates 50 are supported and the threaded column 51 is screwed on to fix the positions of the two clamping columns 41, so that the connecting block 32 is confined in the fixing block 10, thereby improving the stability of the installation of the connecting member 3.

[0027] Although the provision of the connecting member 3 and the fixing block 10 can make the installation of the engine cylinder head body 2 more convenient, when the staff places the engine cylinder head body 2 on the engine cylinder block 1, it is not possible to directly align the slider 30 with the fixing block 10. As a result, the staff needs to adjust the engine cylinder head body 2 when installing the engine cylinder head body 2, and the slider 30 cannot be accurately aligned with the fixing block 10 during adjustment, which is very inconvenient. To solve this technical problem, the present embodiment provides a guide structure 6 on the upper surface of the engine cylinder block 1 and the bottom surface of the engine cylinder head body 2 for facilitating the installation of the engine cylinder head body 2. The guide structure 6 includes a plurality of guide holes 60 opened on the engine cylinder block 1 and a plurality of guide posts 61 fixedly connected to the engine cylinder head body 2. When the engine cylinder head body 2 is placed, the guide posts 61 are aligned with the guide holes 60. Then, the engine cylinder head body 2 is placed so that the guide posts 61 are inserted into the guide holes 60, so that the position of the engine cylinder head body 2 is defined, thereby aligning the slider 30 with the fixing block 10. When adjusting, it is only necessary to swing the engine cylinder head body 2 so that the guide posts 61 are inserted into the guide holes 60, making the installation of the engine cylinder head body 2 more convenient.

[0028] Although the setting of the connecting piece 3 makes the installation of the engine cylinder head body 2 more convenient, the engine cylinder head body 2 does not have a top-down force acting on the engine cylinder block 1, which may cause a gap between the engine cylinder head body 2 and the engine cylinder block 1. The existing technology fills the gap by placing a sealing oil gasket between the engine cylinder head body 2 and the engine cylinder block 1, but without this top-down force, the sealing oil gasket cannot be pressed. Although the gravity of the engine cylinder head body 2 itself can provide this force, it is still not enough to press the sealing oil gasket to completely fill the gap. To solve this technical problem, the present embodiment provides a connecting tension spring 7 in the slide groove 20, one end of the connecting tension spring 7 is located on the top surface of the slide groove 20 and is fixedly connected to the engine cylinder head body 2, and the other end is fixedly connected to the slider 30. By pulling the slider 30 downward and then rotating the rotating block 31, the connecting block 32 is extended into the plug-in interface 11. At this time, the tension of the connecting tension spring 7 will act on the engine cylinder body 1 as a whole through the connecting member 3, so that the connecting tension spring 7 pulls the engine cylinder head body 2 to compress the engine cylinder body 1, thereby reducing the possibility of a gap between the engine cylinder head body 2 and the engine cylinder body 1.

[0029] After the connecting tension spring 7 ages and rusts, it may break. The force generated after the breakage may cause the slider 30 to be thrown out of the slide groove 20. In order to solve this technical problem, in this embodiment, a protective structure 8 is provided on the left and right sides of the slide groove 20 and the left and right sides of the slider 30 to prevent the slider 30 from escaping from the slide groove 20. The protective structure 8 includes a protective groove 80 arranged on the left and right sides of the slide groove 20 along the height direction of the slide groove 20 and a protective block 81 fixedly arranged on the left and right sides of the slider 30 and one end extending into the protective groove 80. The protective block 81 extends into the protective groove 80 to limit the slider 30 from escaping from the slide groove 20, but does not affect the up and down sliding of the slider 30.

[0030] Specific implementation process: pick up the engine cylinder head body 2 so that the guide column 61 is aligned with the guide hole 60, then place the engine cylinder head body 2 on the engine cylinder block 1, so that the guide column 61 is inserted into the guide hole 60, then pull the slider 30 downward, and then rotate the rotating block 31 so that the connecting block 32 extends into the plug-in interface 11. At this time, the tension of the connecting spring 7 will act on the engine cylinder block 1 as a whole through the connecting member 3, and then push the two clamping columns 41 into the connecting groove 42 through the two fixing plates 50, and then hold the two fixing plates 50 and screw on the threaded column 51 to fix the position of the two clamping columns 41, so that the installation of the engine cylinder head body 2 is completed.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
