Detailed Description

In order to facilitate replacement of a new corrosion-resistant cap and further solve the problem that rust formed by corrosion-resistant paint on the top of a piston is not convenient to clean in the prior art, the embodiment of the utility model provides a corrosion-resistant engine piston. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present embodiment provides a corrosion-resistant engine piston, which includes a piston body 1, and a ring groove 11 for installing an air ring is formed on an outer side wall of the piston body 1.

1 top slidable mounting of piston body has corrosion-resistant cap 2, and corrosion-resistant cap 2 replaces the corrosion-resistant coating to the corrosion-resistant function on piston body 1's top to through the corrosion-resistant cap 2 of being convenient for more renew, solve the problem that the corrosion-resistant coating at piston top formed rust of being not convenient for clear up among the prior art.

The two side walls of the inner cavity of the corrosion-resistant cap 2 are rotatably provided with fixing devices 4 which play a role in connecting and fixing the piston body 1, one side of each fixing device 4 is connected with an adjusting device 3 for controlling the rotation of the fixing device 4, and the fixing devices 4 are controlled by the adjusting devices 3 to connect the corrosion-resistant cap 2 with the top of the piston body 1.

When the corrosion-resistant cap 2 needs to be replaced, the fixing device 4 can not fix the corrosion-resistant cap 2 any more only by reversely sliding the adjusting device 3, so that the purpose of convenient replacement is achieved.

For better corrosion-resistant effect to

piston body

1, 2 inside recesses 23 of having seted up of corrosion-resistant cap, the top of recess 23 and piston body 1 all sets up to round platform type structure, the area of contact on increase corrosion-resistant cap 2 and piston body 1 top, thereby make the sealed effect between corrosion-resistant cap 2 and the piston body 1 better, prevented that fluid from getting into the top of piston body 1 and corroding, thereby reach the better purpose of corrosion-resistant effect to piston body 1.

In order to fix the corrosion-resistant cap 2 conveniently, the two sides of the groove 23 are provided with rotating grooves 22 for rotating the fixing device 4, the fixing device 4 comprises a rotating block 41 and a clamping block 42, one end of the rotating block 41 is rotatably installed inside the rotating groove 22, the other end of the rotating block 41 is connected with the adjusting device 3, the rotating block 41 is connected with the adjusting device 3 and the clamping block 42, the rotating block 41 is rotated through the adjusting device 3, and therefore the rotating block 41 drives the clamping block 42 to be clamped with the clamping groove 12.

The outer side wall of the rotating block 41 is fixedly connected with the clamping block 42, the clamping groove 12 matched with the clamping block 42 is formed in the outer wall of the top end of the piston body 1, and the clamping block 42 and the clamping groove 12 are matched for use, so that the corrosion-resistant cap 2 is limited, and the corrosion-resistant cap 2 is not prone to being separated from the piston body 1.

In order to control the fixing device 4 to rotate, the adjusting device 3 includes a handle 31 and a push rod 32, a limit slot 411 is formed in the outer surface of the rotating block 41, one end of the push rod 32 slides in the limit slot 411, and the limit slot 411 enables the sliding force of the push rod 32 in the horizontal direction to be changed into the rotating force of the rotating block 41, so that the control effect is achieved.

The other end of the push rod 32 is fixedly connected with the handle 31, the push rod 32 is limited, and the situation that the push rod 32 cannot be taken out due to too deep sliding is avoided.

The outer side wall of the corrosion-resistant cap 2 is provided with a placing groove 21 matched with the handle 31, so that the normal work of the piston body 1 is not hindered.

In order to improve the adjusting effect of the adjusting device 3 on the fixing device 4, the outer surface of the push rod 32 is sleeved with the compression spring 5, and the compression spring 5 provides elastic force for the push rod 32, so that the rotation of the rotating block 41 controlled by the push rod 32 is faster.

In order to avoid influencing the normal use of the piston body 1, the maximum diameter of the corrosion-resistant cap 2 is the same as that of the piston body 1, and the corrosion-resistant cap 2 is ensured not to influence the normal movement of the piston body 1 in the cylinder.
