Description

Technical Field

[0001] The utility model relates to the technical field of valve tappets, in particular to an impact-resistant high-power internal combustion engine hydraulic buffer valve tappet. Background Art

[0002] The valve tappet is an important part of the engine valve train, which consists of two parts: the valve group and the valve drive group. As one of the main components of the valve drive group, the valve tappet is responsible for transmitting the movement and force of the cam to the valve, thereby controlling the opening and closing action of the valve and ensuring the normal flow of gas in the combustion chamber.

[0003] A large number of valve lifters are contained in the power system of an automobile. When the valve lifters are disassembled for maintenance or repair, all the valve lifters inside the vehicle need to be removed. After the repair is completed, the valve lifters need to be reinstalled. Due to the excessive number of valve lifters, the positions of the valve lifters may be disordered during reinstallation, causing the valve lifters to make abnormal noises when in use. In the prior art, marks are usually added to the outside of the valve lifters with a marker to identify the position of the valve lifters. However, the outside of the valve lifters is often stained with engine oil during repair, which causes the marks on the outside of the valve lifters to be easily erased, thereby affecting the normal assembly of the valve lifters and increasing the repair time of the valve lifters.

The one-way valve 2 is assembled on the top of the second cylinder 3, and the second cylinder 3 is assembled on the top of the first cylinder 1. The oil drain hole 4 is opened on the outside of the second cylinder 3 and the first cylinder 1.

[0025] See also Figure 2 and Figure 3 The first column 1 is externally sleeved with an assembly ring 7, and grooves 71 are evenly distributed on the bottom of the assembly ring 7. The grooves 71 facilitate the assembly of the first column 1 inside the car. At the same time, the assembly ring 7 can prevent external forces from directly acting on the outside of the first column 1, thereby increasing the impact resistance of the first column 1. The interior of the assembly ring 7 is equipped with a shock-absorbing ring made of polyimide, which can absorb part of the impact force.

[0026] See also Figure 4 and Figure 5 The outside of the first column 1 is sleeved with a marking mechanism 5, and the marking mechanism 5 includes an upper ring 51, which can rotate outside the first column 1. A circular groove 53 is opened on the top of the upper ring 51, and the circular groove 53 facilitates the number plate 55 to be identified by the staff, and a glass plate 57 is embedded in the circular groove 53, and the glass plate 57 can protect the number plate 55.

[0027] The bottom of the upper ring 51 is connected with an annular slider 56, and the top of the lower ring 54 is provided with an annular groove matched with the annular slider 56. The annular slider 56 can support the upper ring 51 to slide on the top of the lower ring 54. The bottom of the annular slider 56 is slidably connected with the lower ring 54, and the lower ring 54 can support the upper ring 51. The top of the lower ring 54 is evenly distributed with number plates 55. Numbers can be marked on the top of the number plates 55, and then the device can be marked by different number plates 55.

[0028] A bearing 52 is embedded inside the upper ring 51 , and the bearing 52 is connected to the first column 1 . The lower ring 54 is connected to the first column 1 . The bearing 52 can support the upper ring 51 to facilitate the rotation of the upper ring 51 . Square grooves 58 are provided at both ends of the lower ring 54 .

[0029] The square groove 58 is connected to the spring 62, and the square groove 58 can be used to assemble the locking mechanism 6. The outside of the annular slider 56 is evenly provided with card grooves 59, and the card grooves 59 are adapted to the T-shaped card plate 61. The card grooves 59 facilitate the T-shaped card plate 61 to be inserted into the interior to lock the position of the annular slider 56. Both ends of the lower ring 54 are equipped with locking mechanisms 6.

[0030] The locking mechanism 6 includes a T-shaped card plate 61, which can limit the position of the annular slider 56. The outside of the T-shaped card plate 61 is connected to a T-shaped push plate 63, which facilitates driving the T-shaped card plate 61 to move.

The T-shaped push plate 63 can protect the junction between the T-shaped card plate 61 and the lower ring 54.

[0031] In this solution, the first column 1 is first assembled, and when in use, the assembly ring 7 is used to prevent external impact from directly acting on the outside of the first column 1, thereby increasing the impact resistance of the device;

[0032] Before assembling the first column 1, first press the T-shaped push plate 63 to move, and then drive the T-shaped card plate 61 to move out from the inside of the card slot 59, and then release the limit of the annular slider 56. At this time, the upper ring 51 can be rotated, and then the corresponding positions of the circular groove 53 and the number plate 55 can be adjusted, and then different devices can be marked. After the marking is completed, the locking mechanism 6 is released by releasing the pressure on the locking mechanism 6, and the locking mechanism 6 returns to fix the position of the upper ring 51;

[0033] When the device is in use, the assembled assembly ring 7 is used to prevent external impacts from directly acting on the outside of the first column 1, thereby increasing the impact resistance of the device. The added marking mechanism 5 can quickly mark different devices, thereby avoiding the problem of abnormal noise caused by the disordered position of the device during assembly. At the same time, the added locking mechanism 6 automatically locks the position of the marking mechanism 5 when the marking mechanism 5 is adjusted to complete the marking, thereby preventing the device from being misplaced due to external collisions during maintenance, resulting in the inability to normally distinguish the assembly position of the device.
