DETAILED DESCRIPTION

[0015] The utility model will be further explained in conjunction with the drawings.

[0016] REFERENCE Figs. 1-2As shown, the anti-deformation plastic bearing comprises an outer ring body 1, an inner ring body 2 arranged inside the outer ring body 1, and balls 3 and a retainer 4 arranged between the outer ring body 1 and the inner ring body 2. The outer ring body 1 is composed of a first annular shell 101, a second annular shell 102, a center reinforcing circular ring 103, and an annular reinforcing framework 104. The first annular shell 101 and the second annular shell 102 are fixedly connected. The first annular shell 101 and the second annular shell 102 are fixedly connected by welding. The first annular shell 101 is provided with a first recess 105 on the side close to the second annular shell 102. The second annular shell 102 is provided with a second recess 106 on the side close to the first annular shell 101. The first recess 105 and the second recess 106 are matched to form a receiving groove matched with the center reinforcing circular ring 103. The center reinforcing circular ring 103 is arranged between the first annular shell 101 and the second annular shell 102. The center reinforcing circular ring 103 is symmetrically provided with an annular reinforcing groove 107 at both ends. The annular reinforcing framework 104 is arranged inside the annular reinforcing groove 107. The side wall of the annular reinforcing framework 104 and the reinforcing block 108 is flush with the side wall of the center reinforcing circular ring 103. The center reinforcing circular ring 103, the annular reinforcing framework 104, and the reinforcing block 108 can be made of stainless steel, metal, or the like. The structural strength of the annular reinforcing framework 104 and the reinforcing block 108 is higher than that of the center reinforcing circular ring 103. The center reinforcing circular ring 103 increases the structural strength and stability of the first annular shell 101 and the second annular shell 102. When the first annular shell 101 and the second annular shell 102 are subjected to external force, the force can be transmitted to the center reinforcing circular ring 103 for support and resistance. The annular reinforcing framework 104 increases the structural strength and rigidity of the center reinforcing circular ring 103, effectively supporting the first annular shell 101 and the second annular shell 102. The cooperation of the center reinforcing circular ring 103, the annular reinforcing framework 104, and the reinforcing block 108 effectively increases the wall thickness and structural stability of the first annular shell 101 and the second annular shell 102, thereby improving the structural strength and rigidity of the inner ring body and the outer ring body, and preventing deformation and damage caused by external force.

[0017] A plurality of reinforcing blocks 108 are annularly arranged on the annular reinforcing framework 104. A placing groove 109 is annularly arranged on the annular reinforcing groove 107 and communicates with the annular reinforcing groove 107. The reinforcing block 108 is perpendicular to the annular reinforcing framework 104 to increase the structural strength of the edge of the annular reinforcing framework 104, thereby improving the support performance and further improving the structural stability of the first annular shell 101 and the second annular shell 102.

[0018] The structure of the inner ring body 2 is the same as that of the outer ring body 1. The same structural strength and rigidity make the service life of the plastic bearing more durable.

[0019] The inner walls of the first recess 105 and the second recess 106 respectively abut against the outer walls of the center reinforcing circular ring 103, the annular reinforcing framework 104, and the reinforcing block 108.

[0020] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification or equivalent change of the above embodiment according to the technical essence of the present application falls within the protection scope of the present application.
