They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0045] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0046] The utility model provides a spring installation auxiliary tool, which is suitable for the application scenario of installing and fixing a spring component on a spring bracket during the production process of furniture such as sofas. The tool can assist in the installation and fixing operation of the spring component, thereby saving effort and improving efficiency.

[0047] See also Figure 1 and Figure 2The spring installation auxiliary tool provided in this embodiment includes a clamping and fixing component 1 for clamping and fixing a spring bracket 200, a sliding hook plate 2 for hooking and pulling a spring component 100 and slidably connected to the clamping and fixing component 1, and a rotating operation component 3 rotatably mounted on the clamping and fixing component 1. The rotating operation component 3 has a state in which, after being driven to rotate, the sliding hook plate 2 slides relative to the clamping and fixing component 1 and stretches the spring component 100.

[0048] The spring installation auxiliary tool provided in this embodiment is used as follows:

[0049] S10: First, one end of the spring assembly 100 is mounted and fixed on one end of the spring bracket 200;

[0050] S20: Then, the clamping and fixing assembly 1 clamps and fixes the other end of the spring bracket 200;

[0051] In this embodiment, the clamping and fixing assembly 1 includes a U-shaped plate frame 101 , a plurality of transverse hand-tightening bolts 102 , an adjustable base 103 , and a longitudinal hand-tightening screw 104 .

[0052] The U-shaped plate frame 101 surrounds and forms a bracket insertion space 1011 for one end of the spring bracket 200 to enter; the transverse hand-tightening bolt 102 is threadedly connected to the U-shaped plate frame 101, and is used to clamp and fix the spring bracket 200. Optionally, the number of the transverse hand-tightening bolts 102 is two, and the two transverse hand-tightening bolts 102 are arranged opposite to each other, so as to clamp the spring bracket 200 from the left and right sides.

[0053] S30: Next, the sliding hook plate 2 is slid toward the direction close to the spring assembly 100, and the other end of the spring assembly 100 is hung on the sliding hook plate 2;

[0054] In this embodiment, the sliding hook plate 2 includes a horizontal slide plate 201 and an L-shaped hook plate 202, wherein the L-shaped hook plate 202 is fixed to one end of the horizontal slide plate 201 close to the spring assembly 100. Accordingly, the upper portion of the adjustable base 103 is provided with a hook plate sliding groove 1031 for the horizontal slide plate 201 to slide through. By pushing the horizontal slide plate 201 in a direction close to the spring assembly 100, the L-shaped hook plate 202 can hook and pull the other end of the spring assembly 100.

[0055] S40: rotating the rotating operating assembly 3 so that the sliding hook plate 2 slides relative to the clamping and fixing assembly 1 in a direction away from the spring assembly 100 and stretches the spring assembly 100;

[0056] In this embodiment, the rotating operating assembly 3 is meshedly connected with the sliding hook plate 2. Specifically, the top surface of the horizontal slide plate 201 is provided with a rack portion 2011; the top surface of the adjustable base 103 is provided with a gear groove downwardly connected to the hook plate sliding groove 1031.

[0057] The rotating operating assembly 3 includes a fixed rotating shaft 301 , a rotating gear 302 , a U-shaped rotating frame 303 , an operating rod 304 , and an eccentric arc plate 305 .

[0058] The fixed rotating shaft 301 is fixed on the adjustable base 103 and is located above the gear slot. The rotating gear 302 is rotatably mounted on the middle part of the fixed rotating shaft 301 and is meshed and connected with the rack part 2011 through the gear slot. The U-shaped rotating frame 303 is rotatably connected to the end of the fixed rotating shaft 301. The operating rod 304 is fixed on the top surface of the U-shaped rotating frame 303. The upper end of the eccentric arc plate 305 is fixed on the side of the U-shaped rotating frame 303.

[0059] Specifically, when the operating rod 304 is in a vertical state, the lower end of the eccentric arc plate 305 is separated from the rotating gear 302. Without the eccentric arc plate 305 to resist the rotating gear 302, the rotating gear 302 cannot hinder the sliding of the sliding hook plate 2. Therefore, the sliding hook plate 2 can slide back and forth at will, so that the other end of the spring assembly 100 is hung on the sliding hook plate 2 in step S30.

[0060] The axes of the eccentric arc plate 305 and the rotating gear 302 do not overlap. In the process of gradually rotating the operating rod 304 in the horizontal direction, the distance between the eccentric arc plate 305 and the rotating gear 302 gradually decreases. When the operating rod 304 is at a certain tilt angle, the lower end of the eccentric arc plate 305 will be stuck in the tooth groove of the rotating gear 302. At this time, by continuing to rotate the operating rod 304, the rotating gear 302 can be driven to rotate through the eccentric arc plate 305. The rotating gear 302 will overcome the elastic force of the spring assembly 100 and drive the sliding hook plate 2 to slide in the direction away from the spring assembly 100, thereby achieving the effect of stretching the spring assembly 100.

[0061] S50: After rotating the rotating operating assembly 3 to the tension spring state, fix the other end of the spring assembly 100 to the other end of the spring bracket 200;

[0062] When the operating rod 304 is rotated to a horizontal state, the rotating operating assembly 3 enters a tension spring state. At this time, the other end of the spring assembly 100 is stretched to align with the other end of the spring bracket 200. Therefore, the other end of the spring assembly 100 can be easily installed and fixed on the other end of the spring bracket 200.

[0063] S60: Release the rotating operating component 3 and reset the sliding hook plate 2 to complete the installation and fixing operation of the first spring component 100.

[0064] S70: Adjust the position of the adjustable base 103 and install and fix the second spring assembly 100 .

[0065] In this embodiment, the lower part of the adjustable base 103 is provided with a frame slot 1032 for the U-shaped plate frame 101 to slide through; the longitudinal hand screw 104 is threadedly connected to the bottom surface of the adjustable base 103, and is used to extend into the frame slot 1032 to abut against the U-shaped plate frame 101. Optionally, a scale ruler 1012 is provided on the U-shaped plate frame 101 for indicating the relative position between the adjustable base 103 and the U-shaped plate frame 101.

[0066] When the installation and fixing operation of the second spring assembly 100 needs to be completed, the longitudinal hand screw 104 needs to be loosened first; then the adjustable base 103 needs to be slid to a position aligned with the second spring assembly 100 (the scale 1012 can be used to determine whether the position of the adjustable base 103 is appropriate); then, the longitudinal hand screw 104 needs to be tightened to prevent the adjustable base 103 from sliding; finally, steps S20-S60 can be repeated.

[0067] In summary, the spring installation auxiliary tool provided by the utility model can assist in the installation and fixing of the spring assembly 100 by rotating the rotating operating assembly 3, which greatly saves the effort required by the workers and can effectively improve the installation and fixing efficiency of the spring assembly 100.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
