[0002] Timing chain guide bolts are a crucial component of the engine's timing chain system. They secure the guide rails, ensuring the timing chain maintains correct position and tension during engine operation. The design and manufacture of timing chain guide bolts are crucial to proper engine operation, as they directly impact the engine's timing accuracy and reliability.
[0003] Although the existing timing chain guide bolt has the advantages of preventing the chain from jumping or falling off and having sufficient strength.
[0004] However, the timing chain guide bolt has the following disadvantages: during the operation of the guide chain, vibration or thermal stress will be generated, which will cause the bolt surface to be easily stripped or broken if used for too long, resulting in a reduced service life of the bolt and affecting the operation of the equipment.

It solves the problem raised in the above background technology that vibration or thermal stress will be generated during the operation of the guiding chain, causing the bolt surface to be easily stripped or broken after being used for too long, resulting in a reduced service life of the bolt and affecting the operation of the equipment.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: the timing chain guide bolt includes a hollow rod, a reinforcement component is fixedly installed inside the hollow rod, a connecting block is fixedly installed at the bottom of the hollow rod, a gasket is attached to the bottom of the connecting block, a circular block is fixedly installed at the bottom of the gasket, and torsion rods are fixedly installed on both sides of the circular block.
[0007] Optionally, the reinforcement component includes reinforcing ribs, the interior of the hollow rod is provided with reinforcing ribs, and the other side of the outer surface of the hollow rod is provided with an anti-oxidation coating.
[0008] Optionally, a magnetic film is attached to the outer surface of the connecting block, and a round block is provided at the bottom of the round block.
[0009] Optionally, a cross slot is provided on the surface of the round block, and an outer surface of the torsion rod is provided with anti-slip coating.

[0011] Optionally, a counterweight block is provided inside the circular block, and a waterproof membrane for increasing waterproofness is attached to the outer surface of the circular block.
[0012] The utility model provides a timing chain guide bolt, which has the following beneficial effects:
[0013] 1. The timing chain guide bolt, through the arrangement of the reinforcement assembly, the hollow rod and the screw rod, will generate continuous vibration during the operation of the timing chain guide when the staff installs the screw rod and the hollow rod to the specified position. The reinforcing ribs and the anti-oxidation coating can further reinforce the hollow rod and the screw rod, thereby increasing the service life of the hollow rod and the screw rod.
[0014] 2. The timing chain guide bolt is provided with a circular block, a gasket and a torsion rod. When maintenance personnel need to disassemble the hollow rod and the screw rod, they can rotate the torsion rod to drive the circular block to rotate clockwise, so that the screw rod can be quickly disassembled, thereby facilitating the removal of the screw rod.

At the same time, when the timing chain guide generates vibration during operation, the reinforcing ribs 21 and the anti-oxidation coating 22 can reinforce the screw rod 8 and the hollow rod 1, thereby effectively improving the service life of the screw rod 8. Secondly, when personnel need to disassemble the screw rod 8 and the hollow rod 1, they can use the cross slot inside the circular block 7 to disassemble them, or when it is inconvenient to use external tools, personnel can directly rotate the torsion rod 6 to drive the hollow rod 1 and the screw 8 to be quickly disassembled.
