DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will further elaborate on the present utility model in conjunction with the embodiments given in the drawings.

[0029] Referring to Figures 1-6 as shown,

[0030] A double-calf structure of a spring telescopic massage chair includes a bracket 1, a calf placement member 2, and a foot placement member 3. The calf placement member 2 is installed on the bracket 1. The foot placement member 3 includes a left foot placement member 31 and a right foot placement member 32. Left and right sliding frames 41 and 42 are provided at positions on the bracket 1 corresponding to the left foot placement member 31 and the right foot placement member 32, and the left foot placement member 31 and the right foot placement member 32 are respectively installed on the left and right sliding frames 41 and 42; Springs 5 are connected between both the left sliding frame 41 and the right sliding frame 42 and the bracket 1; When the left foot placement member 31 or the right foot placement member 32 is pushed by the foot, the sliding frame slides on the bracket 1, and the spring 5 stretches and stores elastic potential energy.

[0031] The bracket 1 is used for installation in cooperation with the external massage chair main body. The foot placement member 3 is divided into a left foot placement member 31 and a right foot placement member 32, and can perform independent stretching. The stretching function of this solution is achieved by the user kicking their legs independently. In this solution, a massage component for massage, which can be an airbag or a massage wheel, is provided on the calf placement member 2. When the massage chair is started, the user's left and right feet are respectively located on the left foot placement member 31 and the right foot placement member 32, and the calves are located on the calf placement member 2. The massage chair adjusts the angle, and the left foot placement member 31 and the right foot placement member 32 are lifted off the ground. At this time, the massage chair main body and the calf placement member 2 perform massage actions. The user can perform stretching by retracting and kicking their legs. When kicking the legs, the left sliding frame 41 and the right sliding frame 42 slide outwards on the bracket 1 and stretch the spring 5. At this time, the spring 5 accumulates elastic potential energy to generate elastic force. When the user retracts their legs, the spring 5 provides a reset elastic force to the left sliding frame 41 and the right sliding frame 42. At this time, the left foot placement member 31 and the right foot placement member 32 can maintain contact with the left and right feet, and at the same time provide an auxiliary effect for leg retraction, making it easier for the user to retract their legs and facilitating the user to perform kicking stretching. Moreover, after kicking stretching, the calves are in a straightened state, which can cooperate with the massage component on the calf placement member 2 for massage and relaxation. Through repeated stretching and massage, it is more helpful for the user to relax the legs.

[0032] This solution is based on the manual kicking and retracting of legs for stretching actions, with relatively low costs, and will not generate excessive weight on the bracket 1, avoiding the problem that the connection parts are easily damaged due to the weight of the bracket 1. The design structure is relatively simple, easy to install, and the production efficiency can also be improved. In addition, this structure can provide an effect of adapting to the leg length even when the user does not need to perform stretching actions. The left and right feet can be independently operated. Compared with kicking the legs simultaneously with both feet, it can also improve the user experience and help maintain the body balance state.

[0033] Moreover, compared with the existing technology with electric drive, it can reduce the discomfort caused by the mechanical stretching solution to the user, simplify the structure, reduce costs, and improve production efficiency.

[0034] For convenient installation, as shown in Figure 2 、 3 、4, a number of positioning members 11 are arranged on the bracket 1 along the left sliding frame 41 and the right sliding frame 42. The left sliding frame 41 and the right sliding frame 42 are slidably inserted into the corresponding positioning members 11 and are slidably connected to the positioning members 11.

[0035] The positioning member 11 can be fixed on the bracket 1 or connected to the bracket 1 in a plug-in relationship. At the same time, the left sliding frame 41 and the right sliding frame 42 are also plugged in with the positioning member 11 to form a penetrating state. When the left sliding frame 41 and the right sliding frame 42 slide, they can slide in the positioning member 11. This structure is simpler and also facilitates the connection between the left sliding frame 41 and the right sliding frame 42 and the bracket 1.

[0036] In a further preferred embodiment, referring to Figure 3 and 4 As shown, a limit member 43 is provided at one end of the left sliding frame 41 and the right sliding frame 42 away from the left foot placement member 31 and the right foot placement member 32 respectively. The limit member 43 is used to cooperate with the positioning member 11 to limit the maximum sliding stroke of the left sliding frame 41 and the right sliding frame 42.

[0037] When the left sliding frame 41 and the right sliding frame 42 slide to the maximum stroke, they can be limited by the abutment between the limit member 43 and the positioning member 11, avoiding the maximum extension length of the left sliding frame 41 and the right sliding frame 42, causing the left sliding frame 41 and the right sliding frame 42 to be out of assembly with the bracket 1.

[0038] Of course, in order to facilitate the installation of the limiter 43, the following solution can be adopted for implementation: the limiter 43 is detachably mounted on the left sliding frame 41 and the right sliding frame 42 by bolts. This structure also allows the left sliding frame 41 and the right sliding frame 42 to be easily installed with the positioning member 11.

[0039] Reference Figure 6 As shown, since the left sliding frame 41 or the right sliding frame 42 needs to slide, in order to facilitate its sliding, a plurality of grooves 111 are provided on the inner wall of the through hole on the positioning member 11 for passing the left sliding frame 41 or the right sliding frame 42, and the grooves 111 extend along the sliding direction of the left sliding frame 41 and the right sliding frame 42.

[0040] The contact surface can be reduced by providing the groove 111 , and the groove 111 extends along the sliding direction, making the sliding smoother and reducing the resistance more significantly.

[0041] The through-holes on positioning member 11 corresponding to bracket 1 have the same structure and dimensions as the through-holes on left and right sliding frames 41 and 42. This identical through-hole structure and dimensions allows for a symmetrical design of positioning member 11, eliminating the need to distinguish between bracket 1 and the sliding frames, making production and installation more convenient. The through-hole structure also includes a groove 111 formed in the hole wall.

[0042] Reference Figure 2 and 3As shown in the figure, in a further setting, pulleys 6 are provided at the bottoms of the left sliding frame 41 and the right sliding frame 42. The pulleys 6 can facilitate the handling of the massage chair and at the same time provide a supporting function for the left foot placement member 31 and the right foot placement member 32, avoiding the collision and friction between the left foot placement member 31 and the right foot placement member 32 and the ground when the user steps on them. Similarly, when the massage chair adjusts its posture, it can also avoid the friction between the left foot placement member 31 and the right foot placement member 32 and the ground.

[0043] The above is described in detail as one of the components of the massage chair. When it is applied to the overall structure of the massage chair, the following solutions can also be formed:

[0044] A massage chair includes a seat main body and a double calf structure installed on the seat main body. The double calf structure adopts the spring telescopic massage chair double calf structure as described above, and the bracket 1 is installed on the seat main body.

[0045] Among them, both sides of the bracket 1 are hingedly and cooperatively installed with the seat main body. The hinged cooperative installation can set connecting shafts on both sides of the bracket 1 and use the connecting shafts to be rotatably installed on the massage chair main body to form a hinged cooperation. This hinged cooperation can provide the connecting part for the hinge, but specific posture adjustment still needs to cooperate with the structure of the massage chair main body, such as a hydraulic push rod and other structures, which can push the bracket 1 to rotate and at the same time provide a supporting function.

[0046] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
