At the same time, by arranging the steps, it is convenient to install the reinforcement. When in use, the user can embed the circular ring on the top of the piston. After embedding, the circular ring can improve the deformation resistance of the top and the head. Then the reinforcement can be placed in the piston and contact with the step, and then fixed by bolts for installation. After installation, the reinforcement can improve the deformation resistance of the skirt. Finally, the fixing ring can be embedded in the interior of the piston and contact with the pin seat.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0021] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide a locomotive piston with strong deformation resistance.
[0022] Embodiment 1:
[0023] Reference Figure 1-4, which is the first embodiment of the utility model, provides a locomotive piston with strong anti-deformation properties, including a piston member 100, a ring 200, a reinforcement member 300 and a fixing ring 400.
[0024] Specifically, the piston member 100 includes a piston body 101, a step 104 arranged on the inner side of the piston body 101, and a pin seat 105 arranged on the inner side of the piston body 101. The pin seat 105 is used to install a connecting rod. A plurality of grooves 102 are provided on the outer side of the piston body 101. The plurality of grooves 102 are all annular and are used to install piston rings. A plurality of through holes 103 are provided on the outer side of the piston body 101. The plurality of through holes 103 are equidistantly arranged. The plurality of through holes 103 mainly function to allow the oil scraped off by the oil ring to flow into the inner cavity of the piston.
[0025] Furthermore, an anti-expansion steel sheet 106 is provided inside the piston body 101. The anti-expansion steel sheet 106 can reduce the thermal expansion of the piston body 101, thereby preventing the piston from getting stuck due to thermal expansion, and has an excellent anti-thermal expansion effect.
[0026] Specifically, the ring 200 is embedded in the top of the piston body 101. The ring 200 is a fiber-reinforced aluminum alloy ring 200. The ring 200 can be embedded in the top of the piston body 101. Due to the high strength of the ring 200, the ring 200 can improve the deformation resistance of the top and head of the piston body 101 after embedding.
[0027] Specifically, the reinforcement 300 includes a connecting rod 301 bolted to the step 104 and reinforcement plates 302 arranged at both ends of the connecting rod 301. The outer sides of the two reinforcement plates 302 are in contact with the inner side of the piston body 101. The two reinforcement plates 302 are arc-shaped. The reinforcement 300 can be placed in the piston body 101 and contact with the step 104, and then fixed by bolts for installation. After installation, the reinforcement 300 can increase the thickness of the piston body 101, thereby improving the deformation resistance of the skirt of the piston body 101.
[0028] Specifically, the fixing ring 400 is embedded in the interior of the piston body 101 and can be embedded in the interior of the piston body 101 and contact the pin seat 105. After embedding, the fixing ring 400 can increase the thickness of the piston body 101, that is, improve the deformation resistance of the skirt of the piston body 101 for easy use.
[0029] The working principle and use process of the utility model are as follows: when in use, the user can embed the ring 200 on the top of the piston body 101. Due to the high strength of the ring 200, the deformation resistance of the top and head of the piston body 101 can be improved through the ring 200 after embedding. Then the reinforcement 300 can be placed in the piston body 101 and contact with the step 104, and then fixed by bolts for installation. After installation, the reinforcement 300 can increase the thickness of the piston body 101, which can improve the deformation resistance of the skirt of the piston body 101. Finally, the fixing ring 400 can be embedded in the interior of the piston body 101 and contact with the pin seat 105. After embedding, the fixing ring 400 can increase the thickness of the piston body 101, which can further improve the deformation resistance of the skirt of the piston body 101 for use. Then, the anti-expansion steel sheet 106 can reduce the thermal expansion of the piston body 101 to prevent the piston from getting stuck due to thermal expansion, and the anti-thermal expansion effect is excellent.
