[0029] The bed with a movable break and its application technical effects will be described in detail below through specific implementation structures.

[0030] The bed with a movable break, as Figure 1 shown, comprises a bed frame 100, a traveling frame 200, a bed surface 13, and roller chains 300.

[0031] The bed frame 100 is formed by enclosing two bed side plates 2 and two bed end plates 1.

[0032] On the upper part of the inner walls of its two bed side plates 2, there are groove rails 4 with opposite openings for the horizontal movement of the traveling frame 200. As Figure 3 shown, at the top of the bed side plate 2, there is a right-angled horizontal inner edge 3 covering the groove rail 4, and the inner edge 3 extends forward and backward to the bed end plate 1. There is a spacing left between the two ends of the groove rail 4 and the bed end plate 1 for the roller chains to pass through as described below.

[0033] As Figure 1 , Figure 3 shown, four chain guide rollers 14 are rotatably provided at the four corners, front and back, up and down, between the two bed side plates 2 and close to the two bed end plates 1.

[0034] The described transfer rack 200 is a roller rack that is surrounded by two side plates 6 and two end plates 5 on four sides and can move back and forth along the groove track 4 in the bed frame 100, and the transfer rack 200 is at least open at the top.

[0035] As Figure 2 shown, two parallel guide rollers 9 are respectively arranged in the front and rear of the transfer rack 200 close to the front and rear end plates 5. In this embodiment, both ends of the guide roller 9 are rotationally matched with the side plates 6, and the shaft ends extending to the groove track are installed with transfer wheels 20 that cooperate with the groove track 4. The transfer rack 200 moves back and forth along the groove track 4 in the bed frame 100, and the distance between the two guide rollers 9 forms the bed surface gap W.

[0036] The roller chain 300 is installed and connected to the transfer rack 200. As Figure 2 shown, a starting chain roller 10 parallel to the guide roller 9 is rotatably supported between two support plates 8 outside the two end plates 5, and a chain roller wheel 11 that cooperates with the groove track 4 is installed on the roller shaft of the starting chain roller 10.

[0037] The described roller chain 300 is a roller belt type chain assembly that is chain-connected by hinge plates 12 between the starting chain rollers 10 before and after the transfer rack 200 with a number of chain rollers 22 identical to the starting chain rollers 10, and is tensioned and wound around the four chain guide rollers 14, as Figure 1 shown.

[0038] Among the four chain guide rollers 14, in this embodiment, two of the upper front and rear chain guide rollers are selected as driving rollers, and are respectively drivingly connected to driving motors 17 in opposite directions. As Figure 3 shown, the chain guide roller 14 is a toothed disc on the guide roller shaft 15, and a number of circular notches for fitting with a part of the surface of the corresponding chain roller 22 are provided thereon, forming a tooth shape as Figure 1 shown, for buckling the chain roller 22 and transmitting the power of the driving motor 17. The two driving motors 17 in opposite directions drive the roller chain 300 to reciprocally drive the transfer rack 200 to move.

[0039] The bed surface 13 is a flexible belt that is laid on the chain rollers 22 and the starting chain rollers 10 between the two bed end plates 1 and sinks into the transfer rack 200 between the two guide rollers 9. Between the two guide rollers 9 in the transfer rack 200, that is, on the flexible belt in the transfer rack 200, a mounting base plate 7 for installing components not limited to massage components is fixed, and the mounting base plate 7 can install physical therapy components such as infrared physiotherapy devices and vibrating head massagers.

[0040] The chain roller 22 described above, preferably the same as the guide roller 9, the chain roller 22 also includes a starting chain roller 10 and a guide roller 9. Preferably, the roller body is a spindle-shaped roller with a diameter gradually decreasing from the middle to both ends, forming a massage surface more beneficial to the human body. When the motor 17 drives the chain guide roller 14 to rotate in one direction, the circular concave teeth of the chain guide roller 14 engage with the corresponding chain roller 22, forming a driving force to drag the moving frame 200 to move forward or backward. The chain roller 22, including the starting chain roller 10 and the guide roller 9, and the physiotherapeutic devices in the break w of the moving frame 200 all play their respective massage or other physiotherapeutic functions, providing comprehensive physiotherapeutic treatment for the human body.

[0041] The starting chain roller 10, the chain roller 22 and the guide roller 9 described above preferably have a roller length that is close to and not greater than the distance between the edges of the two inner edges 3.
