[0003] However, since the existing plastic shells are arranged on the two outer sides of the tripod by engaging the tenons and the fixing holes with each other, it is often difficult to align the position during assembly and it is time-consuming. In addition, after a period of use, the The plastic shells are easily subject to repeated impacts by external forces, causing the tenon and the fixing hole to loosen, and the plastic shells are peeled off from both sides of the tripod; in addition, the tenon and the fixing hole are easily broken or deformed due to the limited plastic material. As a result, the plastic shells cannot be firmly combined with the tripod. This not only causes more obvious damage, but also produces abnormal noises of wear and tear during use. It is really necessary to improve the invention

Abstract

The invention relates to a manufacture method of a trundle protection frame, which comprises the steps of: taking a die, placing a trundle body in the die, ejecting plastics in the die to ensure that the plastics cover the whole trundle body, after the plastics are cooled, taking the trundle body from the die so that the plastics form a plastic housing covering on the surface of the trundle body, and further forming a protection frame for a trundle. Therefore, the plastic housing is stably combined and integrally wrapped on the surface of the trundle body so as to be difficult to strip and drop completely; and the trundle protection frame has the effects of strengthening supporting degree of the protection frame and preventing the trundle from being easily damaged under external force.

Description

technical field [0001] The invention relates to a method for manufacturing a caster protective frame, especially a method that can firmly combine the plastic shell and completely cover the surface of the tripod body, so that it is not easy to peel off at all, and has the ability to strengthen the support of the protective frame and block external forces. Effects that are easily destroyed. Background technique [0002] Generally, the protective frame of existing casters at least includes a tripod and two plastic shells respectively assembled on both sides of the tripod. Fixing holes are provided on the two outer sides of the tripod so that the plastic shells can be snapped together to protect the tripod. [0003] However, since the existing plastic shells are arranged on the two outer sides of the tripod by engaging the tenons and the fixing holes with each other, it is often difficult to align the position during assembly and it is time-consuming. In addition, after a perio...
