Abstract

The invention discloses an elastic caster assembly applied to household mobile doors and windows, which comprises a self-locking lever shrapnel and a non-metallic shell, the lower part of the non-metallic shell is provided with a pulley groove, and the front ends of both sides of the pulley groove are provided with pulley bearing holes , the pulley is installed between the pulley bearing holes through bearings; the rear ends of both sides of the pulley groove are provided with positioning pieces, and the positioning pieces are installed in the positioning pieces; the upper end of the non-metal shell is provided with a shrapnel insertion port, and the shrapnel insertion port extends to the The inside of the metal shell; the upper part of the rear end of the non-metallic shell is provided with a thimble insertion hole, and the thimble insertion hole extends horizontally to the interior of the non-metallic shell and communicates with the lower part of the shrapnel insertion port; the self-locking lever shrapnel is inserted into the non-metallic shell The shrapnel on the upper part of the body is inserted into the opening, and the self-locking fixing buckle at the lower end of the self-locking lever shrapnel is engaged with the end of the thimble insertion hole. It reduces costs, pushes and pulls smoothly, produces no noise during use, is easy to install, has simple production process steps, and is environmentally friendly and energy-saving.

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
