Elastic castor assembly applied to household movable door window

Abstract

The invention discloses an elastic castor assembly applied to a household movable door window. The elastic castor assembly comprises a self-locking lever shrapnel and a non-metallic shell. The lower portion of the non-metallic shell is provided with a pulley groove. The front ends of the two sides of the pulley groove are provided with pulley bearing holes. A pulley is arranged between the pulleybearing holes through a bearing. Positioning piece openings are formed in the back ends of the two sides of the pulley groove. Positioning pieces are arranged in the positioning piece openings. The upper end of the non-metallic shell is provided with a shrapnel inserting opening. The shrapnel inserting opening extends to the interior of the non-metallic shell. A thimble inserting hole is formed inthe upper portion of the back end of the non-metallic shell. The thimble inserting hole horizontally extends to the interior of the non-metallic shell and communicates with the lower portion of the shrapnel inserting opening. The self-locking lever shrapnel is inserted into the shrapnel inserting opening on the upper portion of the non-metallic shell. A self-locking fixing buckle at the lower endof the self-locking lever shrapnel is in clamped combination with the end part of the thimble inserting hole. According to the elastic castor assembly, the cost is reduced, pushing and pulling are smooth, no noise is generated during using, installation is convenient, production process steps are simple, and environmental protection and energy saving are achieved.

Description

technical field [0001] The invention relates to the technical field of household accessories, in particular to a caster, in particular to an elastic caster assembly applied to movable doors and windows of household. Background technique [0002] With the improvement of people's living standards, more and more household items have entered people's homes. In order to save space, many household items will choose to install movable doors and windows, which are not only beautiful in appearance, but also convenient to open and close. There is no need to carefully calculate whether the indoor space will affect It opens and closes. [0003] Mobile doors and windows, wardrobe doors and windows, or glass sliding doors can be seen everywhere in life, and the lower end is usually equipped with elastic caster components. Such as figure 1 As shown, the currently commonly used elastic caster assembly usually consists of a metal wheel frame for installing pulleys and bearings, a nylon / rub...

AI Technical Summary

Problems solved by technology

[0005] 1. During the use of the metal wheel frame, the push and pull is not smooth enough, and it is easy to produce sharp and harsh noises;

[0006] 2. The cost of the metal material itself is relatively high, and noise pollution will also be generated during the production process;

[0007] 3. Due to the need to use oil materials in the metal processing process, this not only increases the cost, but also pollutes the environment;

[0008] 4. After the stamping is completed, the metal wheel frame needs to undergo secondary processing, such as: electroplating, blackening, electrophoresis, painting, cooling, etc. These process steps usually produce substances that pollute the environment, which increases the process steps , which increases the production cost and reduces the production efficiency
