Description

Combined roller seat

This creation belongs to the field of cabinet furniture accessories, especially for a combined roller seat, which is used to drive the slide rails for relative sliding. The modular design can be used to change the length of the slide rails of different lengths, greatly reducing the manufacturing. The time of the mold opening cost.

According to the following, the general hidden slide rail is installed between a drawer and a cabinet body in the following manner, so that the existence of the slide rail is not seen from the outer side surface, and the hidden slide rail has the same two-section or The three-section structure is designed to drive the hidden slide rails to be relatively slipped by a sliding member. The slider is usually designed as a ball bushing by a G-shaped bushing body spaced on the sides thereof. A plurality of accommodating grooves are provided, and the predetermined dies and the special machine are respectively used to respectively insert the upper and lower sides of the bushing body into the balls. After the balls are respectively assembled with the corresponding rail members, the two opposite rail members can be relatively slipped, but the ball bushings are designed to pass the balls one by one through a special mold and a special machine. The bushing body is installed in the body, so that the length cannot be adjusted according to actual needs, and the mold opening and adjustment must be repeated, which not only increases the manufacturing difficulty, but also increases the manufacturing cost.

For example, the Republic of China New Patent Publication No. M272893 "Improvement of Ball Bushing for Slide Rails in Concealed Slide Rails" is disclosed in the vicinity of the upper wall of the bushing body of the ball bushing, and has a thinner portion. The mold is easy to spread and placed in a simple structure. The special machine combines the balls into its respective receiving slots, which not only assembles quickly but also greatly reduces the group. Special machine and mold costs. Another example is the Republic of China New Patent Bulletin No. M319340, "Improved Slide Rail Ball Bushings for Concealed Slide Rails", which is disclosed on the two sides of the bushing body by a plurality of pivoting slots and two spaced apart The pivoting of the pivoting block of the side lining plate allows the lining plates to be pivotally spread and placed in a mold of a simple structure, and the number of balls and the number of wheel bodies are set with a simple special machine. The assembly speed is fast, and the cost of assembling the special machine and the mold can be greatly reduced, and the positioning concave edges of the bushing body can respectively provide the two positioning balls of the pivoting block of the side lining plate respectively. Side embedding to prevent ball detachment, and better positioning effect, which can improve product yield and assembly process without worrying about ball falling out, and can be directly placed on hidden slide rails by simple special unit. Above, it also achieves the effect of saving manufacturing costs and assembling quickly and easily.

However, the various ball bushings described above greatly increase the convenience of assembling the balls, and reduce the cost of assembling the special machine and the mold. However, when the applicability of the slide rails of different lengths is required, it is necessary to separately manufacture the mold. In view of this, the creator designed a modular combined roller seat structure that can be assembled through the male and female connectors to quickly adjust the length according to the needs of the use, without the need to open a separate mold or use special Assembly machine, so it can reduce manufacturing costs
