Description

Technical Field

[0001] This utility model relates to the technical field of sofas and chairs, and in particular to the technical field of a spring-loaded, limit-positioning, flexible spring-operated chair. Background Technology

[0002] Driven by modern health concepts, horizontal rhythmic devices, with their functions of promoting blood circulation and relieving fatigue, are widely used in rehabilitation therapy and home health care. Furthermore, spring-supported rhythmic chairs offer a gentler and more comfortable feel compared to those with guide rails and spring-loaded mechanisms. A utility model patent with patent number CN221750032U discloses an elastic base frame assembly and massage furniture. The horizontal rhythmic device uses a structure combining spring support and mechanical drive to achieve the device's horizontal swing function. However, this device has revealed several technical defects in actual use: First, traditional support structures often use a method of fixing the spring ends with welded discs. The welding process easily damages the spring surface, forming cracks or gaps. Under long-term high-frequency vibration, the springs are prone to breakage, significantly shortening the device's lifespan. Second, during operation, due to uneven weight distribution, the springs tilt 360 degrees horizontally, causing the drive mechanism to bear significant torque. After prolonged operation, the drive components deform or wear, creating gaps and increasing operating noise, severely impacting the user experience. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a flexible spring rhythmic chair with spring plate limiting, which solves the problem that existing spring-supported rhythmic sofas do not have limiting in the left and right directions, which can easily lead to damage to the drive mechanism.

[0004] To achieve the above objectives, this utility model proposes a flexible spring rhythmic chair with a spring plate limiting mechanism, comprising a base frame, a horizontal rhythmic frame, and a support spring module. The support spring module for horizontally supporting the horizontal rhythmic frame is provided between the base frame and the horizontal rhythmic frame; a drive mechanism is fixed on the base frame for driving the horizontal rhythmic frame to vibrate back and forth; and a bidirectional spring plate is provided between the base frame and the horizontal rhythmic frame for limiting only the left and right movement of the horizontal rhythmic frame.

[0005] Preferably, the drive mechanism includes a drive base, a drive motor, a crankshaft, a rocker arm, and a connecting push-pull seat. The drive motor is fixed on the drive base, and the rotation shaft of the drive motor is connected to the crankshaft via a transmission belt. One end of the rocker arm is mounted on the crankshaft, and the other end is hinged to the connecting push-pull seat, which is fixed on a horizontal rhythm frame.

[0006] Preferably, the support spring module includes a spring and a cast iron block, with the cast iron block being heat-melted and solidified at both ends of the spring.

[0007] Preferably, the cast iron block is provided with threaded holes, which are fixed to the base frame or horizontal rhythm frame by bolts.

[0008] Preferably, the bidirectional spring plate includes upper and lower spring plates and front and rear spring plates. The front and rear spring plates are vertically arranged with their surfaces facing the direction of movement. The upper and lower spring plates are horizontally arranged and are integrally bent and formed with the front and rear spring plates.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a two-way spring plate to limit the horizontal rhythm frame in the left and right directions, while not affecting the characteristics of the support spring module's up, down, forward and backward movement. This ensures the comfort of the spring rhythm chair, avoids damage to the drive mechanism, and has a simple structure and low cost. Attached Figure Description

Detailed Implementation

[0016] See Figure 1This utility model discloses a flexible spring-loaded rhythmic chair with a spring plate limiting mechanism, comprising a base frame 1, a horizontal rhythmic frame 2, and supporting spring modules 4. A supporting spring module 4 is disposed between the base frame 1 and the horizontal rhythmic frame 2 to horizontally support the horizontal rhythmic frame 2. A sofa or bed can be fixed on the horizontal rhythmic frame 2. The supporting spring module 4 needs to have a certain strength to support a human body, and the number of supporting spring modules 4 can be set according to actual needs. A drive mechanism 3 is fixed on the base frame 1 to drive the horizontal rhythmic frame 2 to vibrate back and forth. The drive mechanism 3 is used for... The drive mechanism 3 can be a crankshaft 33 mechanism, a cam mechanism, or a linear motion motor mechanism. A bidirectional spring plate 5 is set between the base frame 1 and the horizontal rhythm frame 2 to limit the left and right movement of the horizontal rhythm frame 2. Since the spring 41 can tilt horizontally 360 degrees, the uneven distribution of human body weight will cause tilting during the drive mechanism 3 to drive the horizontal rhythm frame 2 to move back and forth. The drive mechanism 3 itself has to bear a large torque. After long-term operation, the components of the drive mechanism 3 will form gaps due to deformation or wear, resulting in increased noise.

[0017] Specifically, such as Figure 2 As shown, the drive mechanism 3 includes a drive base 31, a drive motor 32, a crankshaft 33, a rocker arm 34, and a connecting push-pull seat 35. The drive motor 32 is fixed on the drive base 31, and the rotation shaft of the drive motor 32 is connected to the crankshaft 33 via a transmission belt. One end of the rocker arm 34 is mounted on the crankshaft 33, and the other end is hinged to the connecting push-pull seat 35. The connecting push-pull seat 35 is fixed on the horizontal rhythm frame 2. The drive motor 32 drives the crankshaft 33 to rotate, which in turn drives the rocker arm 34 to vibrate back and forth, ultimately driving the horizontal rhythm frame 2 to reciprocate. Specifically, as shown... Figure 4 As shown, the supporting spring module 4 includes a spring 41 and a cast iron block 42. The cast iron block 42 is heat-melted and solidified at both ends of the spring 41. Traditionally, discs are welded to both ends of the spring 41, holes are drilled in the discs, and the spring 41 is then fixed to the base frame 1 and the horizontal vibration frame 2. However, welding can damage the surface of the spring 41, causing cracks or gaps, making it prone to breakage under prolonged vibration. By melting molten iron and placing the ends of the spring 41 in the molten iron, followed by rapid cooling, a cast iron block 42 is formed at the ends of the spring 41. This method does not damage the surface of the spring 41 and extends its lifespan. It should be noted that the cast iron block 42 has threaded holes, which are bolted to the base frame 1 or the horizontal vibration frame 2. The upper end of the cast iron block 42 of the spring 41 is fixed to the horizontal vibration frame 2, and the lower end of the cast iron block 42 of the spring 41 is fixed to the base frame 1.

[0018] It is understandable that, such as Figure 3As shown, the bidirectional spring plate 5 includes upper and lower spring plates 51 and front and rear spring plates 52. The front and rear spring plates 52 are vertically arranged with their surfaces facing the direction of movement. The upper and lower spring plates 51 are horizontally arranged and are integrally bent with the front and rear spring plates 52. During the forward and backward movement of the bidirectional spring plate 5, the upper and lower spring plates 51 will move up and down slightly with the horizontal rhythm frame 2, and the front and rear spring plates 52 will swing back and forth with the horizontal rhythm frame 2.

[0019] The working process of this utility model:

[0020] In the operation of this utility model, a flexible spring rhythm chair with spring plate limiting works by driving a crankshaft 33 to rotate via a drive motor 32, which in turn drives a rocker arm 34 to vibrate back and forth, ultimately driving a horizontal rhythm frame 2 to reciprocate back and forth. The spring 41 swings back and forth in the front-to-back direction with the drive of the rocker arm 34, and also moves up and down due to inertia. During this process, the upper and lower spring plates 51 move up and down slightly with the horizontal rhythm frame 2, and the front and rear spring plates 52 swing back and forth with the horizontal rhythm frame 2, limiting the left and right movement of the horizontal rhythm frame 2.

[0021] This utility model discloses a flexible spring rhythmic chair with a spring plate limiting mechanism. By using a bidirectional spring plate 5 to limit the horizontal rhythmic frame 2 in the left and right directions, it does not affect the up, down, forward, and backward movement of the supporting spring module 4. This ensures the comfort of the spring 41 rhythmic chair and avoids damage to the drive mechanism 3. The structure is simple and the cost is low. By using a hot-melt method to connect the cast iron block 42 to the spring 41, the damage to the spring 41 is minimal, which can extend the life of the spring 41 and reduce the maintenance rate.

[0022] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
