Description

Technical Field

[0001] This utility model relates to the field of sliding frame technology, specifically a novel sliding frame for electric telescopic sofas. Background Technology

[0002] Electric retractable sofas are a common piece of living room furniture in modern homes, combining comfort and functionality. These sofas feature an electric retractable function, allowing the length to be adjusted to accommodate different numbers of people. With the diversification of lifestyles, this multifunctional furniture is becoming increasingly popular. Especially in small apartments, electric retractable sofas serve as both a place to sit and lie down, while also saving space. Currently, most electric retractable sofas on the market use sliding rails or hydraulic telescopic rods for their sliding frames. Under frequent use, sliding rails can experience wear, noise, limited load-bearing capacity, lubrication issues, and are also complex to install and have poor environmental adaptability. Hydraulic telescopic rods, on the other hand, are prone to oil leaks, slow response, complex maintenance, high cost, temperature sensitivity, and difficulty in controlling force, all of which affect performance and lifespan.

[0003] Patent document CN222486772U discloses a bottom telescopic adjustable frame for an electric sofa, which "relates to the field of furniture." The bottom telescopic adjustable frame of the electric sofa includes a fixed frame and a sliding support frame slidably disposed inside the fixed frame. The sliding support frame includes a sliding base, a rotating backrest, an auxiliary support rod, and a silent sliding bar. When the bottom telescopic adjustable frame of the electric sofa is extended, the top end of the auxiliary support rod rotates on the back of the rotating backrest and moves with the rotating backrest, while the bottom end of the auxiliary support rod rotates on the fixed frame. This ensures the stability of the rotating backrest when it is flipped. Furthermore, when the rotating backrest is rotated to the top, the auxiliary support rod abuts against the back of the fixed frame for support, thus effectively supporting the rotating backrest and preventing deformation and breakage.

[0004] However, the bottom telescopic adjustment frame of the electric sofa in the aforementioned published literature mainly considers the issue of effectively supporting the rotating backrest to prevent deformation and breakage, which is not conducive to reducing friction and making the sofa telescopic movement smoother.

[0005] In view of this, it is necessary to develop a protective mechanism to reduce friction, make the sofa extend and retract more smoothly, and reduce the load on the motor. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of sliding frame for electric telescopic sofas, so as to solve the technical problem mentioned in the background art of enabling the new type of sliding frame for electric telescopic sofas to have a protective function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel sliding frame for an electric telescopic sofa, comprising: an electric push rod, a push-pull frame, a reinforcing rod, and a pulley sliding device;

[0008] The pulley sliding device includes a pulley guide rail, a connector, and a pulley body. The outer wall of the pulley guide rail is provided with a slide rail. The connector is located on the outer wall of the slide rail. The outer wall of the slide rail is provided with a placement opening that matches the size of the pulley body. The pulley body is located on the outer wall of the connector. The outer wall of the pulley guide rail is provided with an adjustment hole. The pulley bodies are horizontally installed on both sides of the outer wall of the longitudinal panel of the connector. The outer wall of the connector is evenly provided with connection holes. The pulley body is connected to the connector by screws.

[0009] Preferably, the electric push rod is located at the center of the inner bottom of the push-pull frame, the reinforcing rods are respectively located above the side walls of the push-pull frame, the pulley sliding device is located above the reinforcing rod, and the pulley sliding device and the reinforcing rod are fixedly connected and connected to the front and rear end frame rods of the push-pull frame.

[0010] Preferably, the pulley guide rail is a square groove guide rail, and the square groove matches the pulley body. The adjusting hole is used to adjust the tightness of the pulley body, and the cross-section of the connecting member is inverted L-shaped.

[0011] Preferably, the pulley body is placed on the inner wall of the pulley guide rail through the placement port to form a pulley sliding device.

[0012] Preferably, the top of the connector is at the same level as the sliding block on the electric push rod, for connecting to the bottom of the sofa.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by installing a protective mechanism, reduces friction, making the sofa's extension and retraction smoother and reducing the motor load. The sliding frame is placed at the bottom of the sofa, and then the sliding blocks on the connecting parts and the electric push rod are connected to the bottom of the sofa with bolts.
