Modes for Carrying Out the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Referring to Figures 1-5: A spring pad with a pull plate adjustment includes a base plate 1, a plurality of support springs 2 are provided on the base plate 1, a bracket 28 and a lifting rod 24 are provided inside the support spring 2, a rubber support 25 is provided on the lifting rod 24, rollers E20 and F26 are provided on both sides above the bracket 28, and a pull adjustment device 38 is provided on the base plate 1;

[0020] The pulling adjustment device 38 includes a pull rope A22, a pull rope B27, a pull rope C32, and a pull rope D34. The lower part of the base plate 1 is provided with a pull plate A23, a pull plate B30, a pull plate C31, and a pull plate D33 corresponding to the four pull ropes. The four pull plates are arranged side by side, and each pull plate is provided with an adjustment knob 17 at one end. The other end of the pull plate is fixedly connected to the bracket fixed on the base plate 1 through a tension spring A16. The bracket is provided with rollers ABCD corresponding to the pull plates. After the pull rope A22 is connected to the roller A39, one end is fixedly connected to the bottom end of the support spring 2, and the other end passes through the base plate 1 and the roller A39 on the bracket A3 and is fixedly connected to the pull plate A23; one end of the pull rope B27 is connected to the lifting After the bottom end of the lowering rod 24 is fixedly connected, it passes through the bottom plate and the roller B40 on the bracket B4 and is fixedly connected to the pull plate B30. The other end of the pull rope B27 passes through the roller F26 and is fixedly connected to the roller B40 on the bracket and the tension spring B36 on the pull plate B30. The two ends of the pull rope B27 cross the roller B40 on the bracket; one end of the pull rope C32 is fixedly connected to the upper end of the support spring 2, and the other end passes through the bottom plate and the roller C41 on the bracket C5 and is fixedly connected to the pull plate C31; one end of the pull rope D34 is fixedly connected to the upper end of the soft spring 12, and the other end passes through the bottom plate and the roller D29 on the bracket D6 and is fixedly connected to the pull plate D33. The bracket and the bracket are both movably connected.

[0021] Specifically, by rotating the adjustment knob 17 at one end of the pull plate A 23 in the forward direction, the pull plate A 23 and the pull rope A 22 are driven to move toward the adjustment knob 17, and the pull rope A 22 pulls the bottom end of the support spring 2 to gradually rise. After the support spring 2 is compressed, the supporting force increases, and the human body feels that the spring pad changes from soft to hard, and vice versa, it is adjusted from hard to soft, thereby achieving the purpose of adjusting the hard support layer at the bottom of the spring pad. The same as the above-mentioned adjustment method and structure, by rotating the adjustment knob at one end of the pull plate B 30, the pull plate B 30 is driven to pull the lifting rod 24 and the rubber support 25 to gradually rise. When the upper part of the support spring is subjected to the upper weight pressure, the contact distance with the rubber support 25 changes from large to small, and vice versa, the adjustment changes from small to large. A heavier part of the human body feels that the spring pad drops smaller or larger, and the tension of the pull rope B 36 can alleviate the tension of the pull rope B 27 reverse pulling force, so that the rubber support 25 can be lowered, that is, the purpose of adjusting the spring pad to be lowered is achieved; the same as the above adjustment method and structure, by rotating the adjustment knob at one end of the pull plate C 31, the pull plate C 31 and the pull rope C 32 are driven to pull the upper end of the support spring 2 gradually downward, and the human body feels that the spring pad is concave and deepened, and conversely, the adjustment feeling is from concave to convex, that is, the adjustment spring pad has a relatively balanced support force on the curved part of the human body; the same as the above adjustment method and structure, the pull plate D 33 and the pull rope D 34 pulls the upper end of the soft spring 12 downward gradually, and the human body's feeling of the spring pad changes from soft to hard, and vice versa, the human body's feeling of the spring pad changes from hard to soft, thereby achieving the purpose of adjusting the soft or hardness of the soft support layer on the spring pad. The support spring 2 provides hard support for the hard support layer on the lower part of the spring pad, and the soft spring 12 provides soft support for the soft support layer on the upper part of the spring pad. Through the above adjustment method, the adjustment function of the spring pad is simple and easy to operate, with low cost, and is suitable for use by the elderly, minors, students, soldiers and people in special occupations.
