Description

Technical Field

[0001] The present application relates to the field of sofa connectors, and in particular to a sofa connector with an elastic hook. Background Art

[0002] Sofas are usually placed in living rooms or lounges for people to sit or lie down. They are generally composed of seat cushions, backrests and armrests, providing a comfortable sitting experience. Sofas are made of various materials, including leather, fabric, wood, etc., to meet different styles and needs. In order to facilitate the transportation of sofas, connectors are usually fixed on the side of the modular sofa to enable the assembly of multiple sofas. This not only facilitates the transportation of the sofa, but also avoids the problem of displacement of the modular sofa during use.

[0003] Existing sofa connectors are generally male and female connectors, and the two sofas are connected and fixed by interlocking the two connectors. However, this connection method can only achieve left-right connection and fixation, and cannot be locked in the vertical direction. As a result, the connection between the sofas is not stable and can easily cause the two sofas to detach from each other. There is also a risk of pinching hands during installation, which is not conducive to use. Summary of the Invention

[0004] The purpose of the present application is to provide a sofa connector with an elastic hook, which has the advantages of firmly connecting two sofas, preventing them from loosening, and improving the stability of the connection between sofas.

[0007] Preferably, a hand wheel is fixedly connected to the bottom of the rotating shaft, a positioning frame is movably connected to the surface of the rotating shaft, and the rear side of the positioning frame is fixedly connected to the fixing frame.

[0008] Preferably, both sides of the rear side of the inner cavity of the fixing frame are fixedly connected to the limiting rods, the surfaces of the limiting rods are slidably connected to the limiting sleeves, and the opposite sides of the two limiting sleeves are fixedly connected to the first ratchet plate.

[0009] Preferably, a knob is fixedly connected to the front side of the screw, and the rear side of the screw is movably connected to the inner wall of the connection box via a bearing.

[0010] Preferably, a slide rail is fixedly connected to the left side of the inner cavity of the connection box, a slider is slidably connected to the inner cavity of the slide rail, and the right side of the slider is fixedly connected to the second ratchet plate.

[0011] Preferably, mounting holes are provided on the front and rear sides of the top of the mounting plate, and mounting blocks are fixedly connected to both sides of the front and rear sides of the fixing frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By providing a fixing frame, a spring, a first ratchet plate, a mounting plate, a connecting box, a screw, a threaded sleeve, a second ratchet plate, and a tensioning assembly, the mounting plate and the fixing frame can be connected through the cooperation of the first ratchet plate and the second ratchet plate. The elasticity of the spring ensures that the first ratchet plate is always engaged with the second ratchet plate to prevent the two from loosening, so that the two sofas connected to the two can be firmly connected, and the installation process is quick and convenient without the risk of pinching hands.

[0014] 2. By providing a limit rod and a limit sleeve, the first ratchet plate can be limited so that it can only move forward and backward to prevent it from being displaced left and right.

[0025] Embodiment 1: By setting a fixing frame 1, a spring 2, a first ratchet plate 3, a mounting plate 4, a connecting box 5, a screw 6, a threaded sleeve 7, a second ratchet plate 8 and a tensioning assembly 9, the mounting plate 4 and the fixing frame 1 can be connected through the cooperation of the first ratchet plate 3 and the second ratchet plate 8. The elasticity of the spring 2 is utilized to ensure that the first ratchet plate 3 is always engaged with the second ratchet plate 8 to prevent the two from loosening, so that the two sofas connected to the two can be firmly connected, and the installation process is quick and convenient without the risk of pinching hands.

[0026] In one possible implementation, see Figure 1-5 , a sofa connector with an elastic hook, both sides of the rear side of the inner cavity of the fixed frame 1 are fixedly connected to the limit rod, the surface of the limit rod is slidably connected to the limit sleeve, and the opposite sides of the two limit sleeves are fixedly connected to the first ratchet plate 3, the front side of the screw 6 is fixedly connected to the knob 10, the rear side of the screw 6 is movably connected to the inner wall of the connecting box 5 through a bearing, the left side of the inner cavity of the connecting box 5 is fixedly connected to the slide rail, the inner cavity of the slide rail is slidably connected to the slider, and the right side of the slider is fixedly connected to the second ratchet plate 8, the front and rear sides of the top of the mounting plate 4 are provided with mounting holes 11, and the front and rear sides of the fixed frame 1 are fixedly connected to the mounting blocks 12.

[0027] Embodiment 2: By providing a limiting rod and a limiting sleeve, the first ratchet plate 3 can be limited so that it can only move forward and backward to prevent it from being displaced left and right. By providing a knob 10, it is convenient for the user to rotate the screw 6. By providing a bearing, the stability of the screw 6 during rotation can be increased. By providing a slide rail and a slider, the second ratchet plate 8 can be limited so that it can move forward and backward stably. By providing a mounting hole 11, the installation and fixation of the mounting plate 4 can be facilitated. By providing a mounting block 12, the fixing frame 1 can be conveniently installed on the bottom of the sofa.

[0028] On the basis of Example 1, this embodiment describes the tensioning assembly 9 in Example 1. The tensioning assembly 9 includes a rotating shaft 901. The top of the rotating shaft 901 is movably connected to the inner wall of the fixed frame 1. The surface of the rotating shaft 901 is fixedly connected to a cam 902. A push plate 903 is provided on the left side of the cam 902. The right side of the push plate 903 is movably connected to the connecting box 5 through a rotating rod 904. The bottom of the rotating shaft 901 is fixedly connected to a handwheel 905. The surface of the rotating shaft 901 is movably connected to a positioning frame 906. The rear side of the positioning frame 906 is fixedly connected to the fixed frame 1. The push plate 903 is leveled so that it contacts the cam 902. The handwheel 905 is rotated. The handwheel 905 is used to control the rotating shaft 901 and the cam 902 to rotate. The cam 902 rotates and squeezes the push plate 903. After the push plate 903 is squeezed, it drives the rotating rod 904 and the connecting box 5 to move, so that the two sofas are brought closer to each other, preventing a large gap from being formed at the connection after the two sofas are fixed.

[0029] Working principle: Fix the mounting plate 4 and the fixing frame 1 to the bottom of the two sofas to be connected respectively by bolts, then turn the knob 10, and the screw 6 is driven to rotate by the knob 10. The screw 6 cooperates with the threaded sleeve 7 to drive the second ratchet plate 8 to move to the outside of the connection box 5, and then the two sofas are brought closer to each other. At the same time, the connection box 5 enters the inner cavity of the fixing frame 1. Through the cooperation of the spring 2 and the first ratchet plate 3, the first ratchet plate 3 and the second ratchet plate 8 are engaged with each other to complete the connection of the two sofas. When the sofas are separated, the knob 10 is reversed to make the second ratchet plate 8 return to the connecting box 5 to separate the two sofas. After the connection is completed, the push plate 903 can be pushed to make the push plate 903 contact the cam 902, and then the hand wheel 905 is turned. The hand wheel 905 cooperates with the rotating shaft 901 to drive the cam 902 to rotate. The cam 902 rotates and squeezes the push plate 903. After the push plate 903 is squeezed, it drives the rotating rod 904 and the connecting box 5 to move, so that the two sofas are close to each other, avoiding a large gap at the connection after the two sofas are connected.
