The outer cover wraps the massage movement 11 and the flexible guide rail 12. The massage movement 11 is movably connected to the flexible guide rail 12. The massage movement 11 can move up and down along the flexible guide rail 12. A number of waist belts 3 are connected to the outer sides of the flexible guide rail 12. The waist belts 3 are arranged corresponding to each other on the left and right. The waist belts 3 are elastic bandage structures. After being put on, the waist belts 3 are tightened to fit the theater chair 2, and the deformation of the flexible guide rail 12 can achieve the effect of back fitting. A fixing component is arranged at the end of the waist belt 3.

[0021] The fixing assembly includes a connecting block 4 fixedly connected to the end of the waist belt 3, and a cylinder 41 is fixedly arranged inside the two opposite connecting blocks 4 on one side. The connecting block 4 is provided with an embedded card slot on both sides of the cylinder 41. The fixing assembly also includes a bidirectional screw rod 42. The two sides of the bidirectional screw rod 42 are rotated and inserted into the two adjacent cylinders 41. The two sides of the bidirectional screw rod 42 are threadedly connected with a pressure plate 43. The pressure plates 43 on both sides are moved closer to the center or separated to the two ends by rotating the bidirectional screw rod 42. Two guide rods are arranged inside the cylinder 41, and the two guide rods are symmetrical about the central axis of the pressure plate 43. Slide grooves matching the guide rods are opened at both ends of the pressure plate 43, and the pressure plate 43 is slidably sleeved on the outer wall of the guide rod through the slide groove; a rotating shaft is rotatably arranged on the two side walls inside the cylinder 41, and a movable plate 44 is fixedly connected to the rotating shaft, and an extrusion block 45 abutting against the pressure plate 43 is also arranged on the rotating shaft, and the pressure plate 43 abuts against the extrusion block 45 to drive the movable plate 44 to rotate, and limit outlets for the rotation of the movable plate 44 are arranged on both sides of the cylinder 41, and the limit outlets match the embedded card slots.

[0022] Specifically, the extrusion block 45 and the movable plate 44 are in an "L" shape and are both fixed on the rotating shaft. Under normal conditions, the movable plate 44 is away from the pressure plate 43 relative to the extrusion block 45. Therefore, when the pressure plate 43 moves toward the extrusion block 45 on the bidirectional screw rod 42 until it touches the extrusion block 45, under the extrusion of the pressure plate 43, the extrusion block 45 rotates toward the limit outlet, driving the rotating shaft and the movable plate 44 to rotate outward, that is, the movable plate 44 can be unfolded, so that the movable plate 44 is unfolded outward and stuck in the embedded card slot; that is, the two adjacent connecting blocks 4 are connected together; when used specifically, the massage cushion 1 is spread to the shadow When the backrest of the theater chair 2 is moved, the waist belts 3 on both sides are pulled to the back of the theater chair 2, and then the waist belts 3 on both sides are pulled close to insert the bidirectional screw rods 42 and the pressure plates 43 on both sides into the connecting blocks 4 of the two waist belts 3 respectively, and then the bidirectional screw rods 42 are rotated to drive the pressure plates 43 on both sides to go deeper into the two cylinders 41 respectively. Under the extrusion of the pressure plates 43, the extrusion blocks 45 rotate toward the limit outlet, driving the rotating shaft and the movable plate 44 to rotate outward, that is, the movable plate 44 can be unfolded, so that the movable plate 44 is unfolded outward and clamped into the embedded clamping groove, which can achieve the effect of clamping, so that the two waist belts 3 are connected together.

[0023] At the same time, in order to prevent the bidirectional screw rod 42 from rotating in the opposite direction to lock the two connecting blocks 4 under natural conditions, thereby causing the movable plate 44 to retract inward and disengage from the embedded card slot, as a preferred embodiment, the fixing assembly also includes a fixing seat 48 and a one-way ratchet 47, and the two ends of the bidirectional screw rod 42 are sleeved with a sleeve 46, the inner side of the sleeve 46 abuts against the top of the guide rod, the fixing seat 48 is fixedly installed on the back of the theater chair 2, and the stop claw of the one-way ratchet 47 is set on the sleeve 4 6, the inner teeth of the one-way ratchet 47 are arranged on the inner wall surface of the outer end of the cylinder 41, and the inner teeth of the one-way ratchet 47 cooperate with the stop pawl of the one-way ratchet 47 to limit the one-way rotation of the one-way ratchet 47; according to the nature of the one-way ratchet 47, when the two-way screw rod 42 is rotated clockwise, the movable plate 44 can be driven to expand outward, and after expansion, since the stop pawl is stuck to the inner teeth of the one-way ratchet 47, the two-way screw rod 42 cannot be rotated counterclockwise, and therefore the movable plate 44 cannot be retracted, thereby achieving the effect of preventing the occurrence of loosening;

[0024] One end of the sleeve 46 extends beyond the outer end of the cylinder 41, and the outer surface of the sleeve 46 extending beyond the outer end of the cylinder 41 is provided with an external thread, and the fixing seat 48 is provided with an internal thread matching the sleeve 46, and the fixing seat 48 is threadedly locked between two adjacent cylinders 41; during specific use, when the massage cushion 1 is laid on the backrest of the theater chair 2, the waist belts 3 on both sides are pulled to the rear of the theater chair 2, and then the waist belts 3 on both sides are pulled closer, and the two-way screw rod 42 is passed through the fixing seat 48, and the sleeve 46 and the pressure plate 43 are threadedly inserted on both sides of the two-way screw rod 42, and the two-way screw rod 42 and the pressure plates 43 on both sides are respectively inserted into the connecting blocks 4 of the two waist belts 3, and the inner side of the sleeve 46 abuts against the guide rod, and the sleeves 46 on both sides are threadedly connected and fixed with the two ends of the fixing seat 48, and then the connecting blocks 4 on both sides are rotated to complete the clamping.

[0025] As a preferred embodiment, the sleeve 46 is composed of two semicircular sleeves connected by screws. When disassembly is required, the sleeve 46 can be removed, and then the internal fixing component is taken out, and the sleeve 46 is slid outward to release the restriction of the one-way ratchet 47, and then the two-way screw rod 42 is rotated in the opposite direction to separate the two connecting blocks 4.
