Description

Technical Field

[0001] The utility model relates to a telescopic bracket of a leg and foot massager. Background Art

[0002] A leg and foot massager is a device specifically for massaging the leg and foot parts, and it is usually used in conjunction with a massage chair. In order to meet the requirements of different users for the calf length, the leg and foot massager usually includes a telescopic bracket. The telescopic bracket of the existing leg and foot massager either drives its telescopic movement through an electric actuator, with a relatively complex structure and high manufacturing cost; or drives the telescopic bracket to extend by the user stepping on it with the foot, so that it can adapt to the calf length of the user. After the foot leaves, the telescopic bracket contracts and resets under the drive of a spring. The structure is relatively simple, but during the massage process, the force of the spring continuously presses on the user's foot, and it is easy to cause a sense of fatigue after long-term use, reducing the massage experience. Summary of the Invention

[0003] The utility model provides a telescopic bracket of a leg and foot massager, which has a simple structure, low manufacturing cost, can avoid the fatigue caused by long-term stepping on the calf, and improves the comfort of massage.

[0004] The telescopic bracket of the leg and foot massager of the utility model includes a leg bracket and a foot bracket which are slidably connected. A first elastic reset member is arranged between the leg bracket and the foot bracket for driving the two to slide relatively in the direction of approaching each other. A guide rod is arranged on the leg bracket, and the length direction of the guide rod is consistent with the sliding direction of the leg bracket and the foot bracket. A sliding member capable of sliding along the length direction of the guide rod is arranged on the guide rod. A tooth row arranged along the length direction is fixed on the guide rod. A claw is rotatably arranged on the sliding member. One end of the claw is engaged and positioned with the tooth row. A support rod is arranged on the foot bracket. A connecting rod is rotatably connected between the end of the support rod and the other end of the claw. The claw is connected with a second elastic reset member for driving one end of the claw to rotate in the direction of being engaged and positioned with the tooth row. Through the engagement and positioning cooperation between the claw and the tooth row, the locking between the guide rod and the sliding member can be carried out to prohibit the sliding member from sliding along the guide rod. Preferably, the length direction of the support rod is consistent with the sliding direction of the leg bracket and the foot bracket.

[0005] When the user steps on the footrest downward with the foot, the support rod on the footrest drives the claw to rotate through the connecting rod, causing one end of the claw to rotate in a direction away from the tooth row, releasing the locking of the sliding member and the guide rod. The sliding member is driven to slide downward along the guide rod, causing the footrest to slide downward relative to the leg rest, realizing the elongation of the telescopic bracket. When the telescopic bracket extends to the required length, quickly retract the foot, and the stepping force disappears. Under the action of the second elastic reset member, the claw rotates and engages with the tooth row again for positioning and cooperation, forming a lock between the sliding member and the guide rod, preventing the first elastic reset member from driving the footrest to slide upward relative to the leg rest, and keeping the telescopic bracket at this telescopic length. When the user is massaging, the acting force of the first elastic reset member will not press on the user's foot, which can improve the comfort of the massage. After the massage is over, step on the footrest again to separate the claw from the tooth row again, releasing the lock of the sliding member and the guide rod. The acting force of the second elastic reset member presses on the sole of the foot. Since the connecting rod and the claw are in a tensioned state at this time, when slowly lifting the foot, driven by the first elastic reset member, when the support rod moves upward, it pushes the claw and the sliding member upward through the pushing action of the connecting rod, realizing the contraction and reset of the telescopic bracket.

[0006] Further, the tooth row is a ratchet tooth row, and the claw is a ratchet claw. When the ratchet claw moves downward relative to the ratchet tooth row, through the contact and cooperation between the ratchet claw and the ratchet tooth row, the ratchet claw will rotate in a direction away from the ratchet tooth row, so that the elongation action of the telescopic bracket can be smoother and more labor-saving.

[0007] Further, a connecting shaft for rotational cooperation with the claw is provided on the sliding member, and the second elastic reset member is a torsion spring sleeved on the connecting shaft and abutted between the claw and the sliding member, with a compact structure and improved driving effect on the claw.

[0008] Further, the tooth row is fixed on one side of the guide rod, and the width of the tooth row is smaller than the width of this side of the guide rod. The sliding member includes a connecting hole for sliding and sleeving cooperation with the guide rod, and a through groove located on one side of the connecting hole and connected to the connecting hole. The width of the through groove is smaller than the width of this side of the connecting hole. The tooth row is movably arranged at the through groove, which is convenient for the cooperation between the tooth row and the claw, and also improves the sliding cooperation effect between the sliding member and the guide rod, making it not easy for the guide rod and the sliding member to relatively shake.

[0009] Further, a convex column for limiting cooperation with the claw is provided on the sliding member. The setting of the convex column can limit the rotation angle of the claw and improve the linkage cooperation effect between the connecting rod and the claw.

[0010] Furthermore, both the leg support and the foot support include a cross beam and two vertical rods connected to both ends of the cross beam. A sliding connection is formed between the two vertical rods of the leg support and the foot support through sliding sleeves. The cross beam and the two vertical rods of the leg support and the foot support enclose a frame body. The guide rod is arranged at the middle position of the cross beam of the leg support, and the support rod is arranged at the middle position of the cross beam of the foot support, and both are located inside the frame body, improving the force-bearing effect between the leg support and the foot support and making the overall structure of the telescopic support more compact.

[0011] Furthermore, the first elastic reset member is two tension springs arranged inside the frame body. The two tension springs are respectively arranged at positions close to the two vertical rods of the leg support and the foot support. Both ends of the tension springs are respectively connected to the cross beams of the leg support and the foot support, improving the force-bearing effect between the leg support and the foot support and making the overall structure of the telescopic support more compact.

[0012] The beneficial effects of the present utility model are as follows: simple structure, simple operation, low production cost, no pressure on the user's foot during massage, and improved comfort during massage. Description of the Drawings

Through the engagement and positioning between the claw 6 and the tooth row 5, the guide rod 3 and the sliding member 4 can be locked, and the sliding member 4 is prohibited from sliding along the guide rod 3. The axis position of rotation between the connecting rod 8 and the support rod 7 is in an obliquely distributed position relative to the axis position of rotation between the claw 6 and the sliding member 4. When the foot steps on the tripod 2, the support rod 7 pulls the claw 6 to rotate through the connecting rod 8, which can make the connecting rod 8 and the claw 6 in a tensioned state, such as Figure 6 The state shown in FIG. 1 is a state in which the sliding member 4 and the guide rod 3 can be unlocked so that the telescopic bracket can move telescopically.

[0020] Preferably, the length direction of the support rod 7 is consistent with the sliding direction of the leg frame 1 and the foot frame 2.

[0021] When the user steps on the tripod 2 downward with his foot, the support rod 7 on the tripod 2 drives the claw 6 to rotate through the connecting rod 8, so that one end of the claw 6 rotates in the direction of separation from the tooth row 5, so that the lock of the sliding member 4 and the guide rod 3 is released, and the sliding member 4 is driven to slide downward along the guide rod 3, so that the tripod 2 slides downward relative to the leg frame 1, and the telescopic bracket is extended; when the telescopic bracket is extended to the required length, the foot is quickly retracted, the stepping force disappears, and the claw 6 rotates under the action of the second elastic reset member 92 and re-engages with the tooth row 5 to form a locking and positioning match, forming a pair of The locking between the sliding member 4 and the guide rod 3 prevents the first elastic reset member 91 from driving the foot frame 2 to slide upward relative to the leg frame 1, so that the telescopic frame is maintained at the telescopic length. When the user is massaging, the force of the first elastic reset member 91 will not be applied to the user's feet, which can improve the comfort of the massage. When the massage is over, the foot frame 2 is stepped on again to separate the claw 6 from the tooth row 5 again, so that the locking of the sliding member 4 and the guide rod 3 is released, and the force of the second elastic reset member 92 is applied to the sole of the foot. Since the connecting rod 8 and the claw 6 are in a tensioned state (such as Figure 6 As shown in the state shown in the figure, when the foot is slowly lifted, driven by the first elastic reset member 91, the support rod 7 pushes the claw 6 and the sliding member 4 upward through the pushing action of the connecting rod 8 when moving upward, thereby realizing the contraction and reset of the telescopic bracket.
