Description

Technical Field

[0001] The utility model relates to a sofa spring, and more specifically, mainly relates to a sofa spring with multi-directional connection ends. Background Art

[0002] The support spring installed on the sofa base can not only play a supporting role, but also play a buffering role for the sofa's load-bearing capacity, so that it can cooperate with the sponge pad and other facilities on the sofa to improve the comfort of sitting and lying on the sofa. When installing, this type of support spring can be directly hung on the frame of the sofa base in the form of a hook. However, since the size of the sofa frame is not standard, and the support spring is usually considered in terms of efficiency, it is generally mass-produced with uniform specifications. This will result in different sizes of sofa frames When installing support springs of uniform specifications, the length of the support spring cannot be completely matched with it, affecting the use effect of the spring. Therefore, it is necessary to study and improve the support spring structure of uniform specifications. Utility Model Content

[0003] One of the purposes of the present invention is to provide a sofa spring with multi-directional connection ends in view of the above-mentioned shortcomings, so as to solve the technical problems in the prior art that similar supporting springs are limited by their structures and cannot be fully matched and installed on sofa frames of different specifications.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a sofa spring with a multi-directional connection end, comprising a spring body bent in an S shape, one end of the spring body having an S-shaped connection hook, the other end of the spring body being a multi-directional connection end, the multi-directional connection end being a hook bent in an S shape along an X axis, a Y axis and a Z axis, and the hook bent in an S shape along the X axis, the Y axis and the Z axis having at least three connection positions.

[0006] Preferably, a further technical solution is that the terminal end of the multi-directional connection end is U-shaped.

[0007] A further technical solution is: there is a bending portion between the end of the multi-directional connection end and the spring body, there is a gap between the bottom of the bending portion and the bottom of the spring body, and the end and the bottom of the spring body are on the same straight line extending along the spring body.

[0008] A further technical solution is that the material of the spring body is a metal with toughness.

[0009] A further technical solution is: the spring body is used for connecting the hook and the multi-directional connection end, which are respectively mounted between the sofa base frames.

[0010] Compared with the prior art, one of the beneficial effects of the utility model is that a multi-directional connection end is designed at one end of the spring body, and a hook structure that is S-bent along the X-axis, Y-axis, and Z-axis is used, so that the multi-directional connection end can form at least three connection positions in different directions, thereby being adaptable to installation on sofa frames of different widths. In particular, when the specifications of the sofa frame fluctuate, the spring body and the sofa frame can be installed in a completely matching manner through different connection positions. At the same time, the sofa spring with a multi-directional connection end provided by the utility model has a simple structure, is suitable for industrial production, and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram for illustrating an embodiment of the utility model.

[0012] Figure 2 It is a schematic diagram of the installation structure for illustrating an embodiment of the utility model.

[0013] In the figure, 1 is a spring body, 2 is a multi-directional connection end, 21 is a first connection position, 22 is a second connection position, 23 is a third connection position, 3 is a sofa base frame, and 4 is a bending part. DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] refer to Figure 1 As shown, one embodiment of the utility model is a sofa spring with a multi-directional connection end, comprising a spring body 1 bent in an S shape, the spring body 1 can be made of a tough metal; one end of the spring body 1 has an S-shaped connection hook, and different from similar supporting spring structures, the inventor designs the other end of the spring body 1 as a multi-directional connection end 2, and from a three-dimensional coordinate perspective, the multi-directional connection end 2 is a hook bent in an S shape along the X axis, the Y axis, and the Z axis. As shown in the figure, in this embodiment, the hook bent in an S shape along the X axis, the Y axis, and the Z axis has three connection positions after the aforementioned bending, namely, a first connection position 21 closest to the aforementioned connection hook, a second connection position 22 farthest from the aforementioned connection hook, and a third connection position 23 located between the first connection position 21 and the second connection position 22, so that three connection positions in different positions and directions can be realized through the aforementioned bending, and by bending in an S shape along the X axis, the Y axis, and the Z axis, the spring body 1 can also be closely attached to the bottom of the sofa during installation to ensure its elastic support effect.

[0016] In this embodiment, a multi-directional connection end is designed at one end of the spring body 1, and a hook structure is formed that is S-shaped along the X-axis, Y-axis, and Z-axis, so that the multi-directional connection end can form at least three connection positions in different directions, thereby being adaptable to installation on sofa frames of different widths. In particular, when the specifications of the sofa frame fluctuate or differ slightly, the spring body and the sofa frame can be installed in a completely matched manner through different first connection positions 21, second connection positions 22, and third connection positions 23.

[0017] Furthermore, in order to facilitate the use of the same installation method as the same type of supporting spring under normal conditions, the terminal end of the multi-directional connection end 2 may be U-shaped; and as Figure 1 As shown, there is a bending portion 4 between the end of the multi-directional connection end 2 and the spring body 1, and there is a gap between the bottom of the bending portion 4 and the bottom of the spring body 1, and at the same time, the end of the multi-directional connection end 2 and the bottom of the spring body 1 are on the same straight line extending along the spring body 1, that is, the bottom of the bending portion 4 and the spring body 1 and the end of the multi-directional connection end 2 are staggered and are not on the same straight line extending along the spring body 1.

[0018] refer to Figure 1 and Figure 2 As shown, when in use, the spring body 1 is used to be mounted between the sofa base frames 3 respectively through the connecting hooks and the multi-directional connecting ends 2. For sofa base frames 3 of different sizes, the first connecting position 21, the second connecting position 22, and the third connecting position 23 located at different positions at one end of the spring body 1 are connected to the inner hook of the sofa base frame 3. After selecting the most suitable connecting position and the hook for mounting, the spring body 1 is attached to and in close contact with the bottom of the sofa, ensuring that its supporting force can be applied to the bottom of the sofa.
