Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment: As Figures 1-4 shown, a novel sealed plastic ring structure includes plastic arc strips 1 and positioning mortise pins 2. There are four plastic arc strips 1 and four positioning mortise pins 2. Both ends of the plastic arc strip 1 are integrally formed with tenons 101, and the two tenons 101 are arranged vertically and mirror-symmetrically. Mortise holes 102 are formed on both tenons 101. Multiple oil absorption grooves 105 are equidistantly formed on both end faces of the plastic arc strip 1, and oil absorption cotton pads 106 are filled in the oil absorption grooves 105. Multiple carbon fiber strips 107 are filled in the plastic arc strip 1. During use, sealing oil is added to the oil absorption grooves 105, and the oil storage capacity is increased by adsorption through the oil absorption cotton pads 106;
[0023] Both the plastic arc strip 1 and the positioning mortise pin 2 are made of high-temperature resistant and anti-corrosive fluoroplastics. During use, the use of fluoroplastics enhances the overall high-temperature resistance and anti-corrosion ability of the sealed plastic ring;
[0024] The four plastic arc strips 1 are connected end to end to form a ring, and the positioning mortise pins 2 are inserted into the mortise holes 102 between adjacent two plastic arc strips 1. During use, the four plastic arc strips 1 are connected end to end to form a ring, and then the positioning mortise pins 2 are inserted into the mortise holes 102 for fixation;
[0025] Both ends of the positioning mortise pin 2 are circular, and a connecting strip is integrally formed between them. During use, the design with wide ends and a narrow middle achieves the function of mortise and tenon, improving the firmness of positioning;
[0026] Multiple oil seal grooves 103 are longitudinally and equidistantly formed on the inner circumferential wall of the plastic arc strip 1. Chamfers 104 are formed at both ends of the inner circle of the plastic arc strip 1. A communication groove is formed between the oil absorption groove 105 and the chamfer 104. During use, adding heat-conducting oil to the oil seal grooves 103 can effectively improve the heat conduction and lubrication effects of the sealed plastic ring, extending the overall service life. The sealing oil added to the oil absorption groove 105 flows into the chamfer 104 through the communication groove to form an oil seal, enhancing the overall sealing effect;
[0027] The carbon fiber strip 107 is woven from multiple carbon fiber filaments. During use, the overall tear resistance is improved by adding the carbon fiber strip 107.
[0028] Specifically, when the utility model is in use, four plastic arc strips 1 are sequentially inserted between the cathode roller and the sealing end cover, and the four plastic arc strips 1 are connected end to end to form a ring. Then, the positioning dowel pin 2 is inserted into the dowel hole 102 for fixation. Due to the design of the positioning dowel pin 2 with wide ends and a narrow middle, the mortise and tenon effect is achieved, improving the firmness of positioning. During use, the overall tear resistance is improved by adding the carbon fiber strip 107. Also, before use, sealing oil can be added to the oil absorption groove 105, and the oil absorption cotton pad 106 adsorbs it to increase the oil storage capacity. The sealing oil added to the oil absorption groove 105 flows into the chamfer 104 through the communication groove to form an oil seal, improving the overall sealing effect. By adding heat-conducting oil to the oil seal groove 103, the heat conduction and lubrication effects of the sealing plastic ring can be effectively improved, extending the overall service life.
