Description

Technical Field

[0001] The utility model relates to the technical field of back-beating devices, in particular to an electric back-beating device. Background Art

[0002] With the accelerated pace of modern life, high-intensity work can cause physical fatigue, which in turn leads to symptoms of back pain and leg pain. People usually use back beating to eliminate fatigue.

[0003] First, the existing back-beating methods all require the user to hold a back-beating device and hit the sore part of the back. However, since the user's hand can only extend to a limited area and the back is a blind spot, it often takes a lot of time to move the back-beating device to the sore part when beating the back, resulting in cumbersome, time-consuming and labor-intensive steps and poor back-beating effect.

[0004] Second, the existing back-beating devices are all handheld by the user, and since there is often more than one sore spot on the back, the user needs to constantly change the back-beating device to change the striking position when beating the back, which is cumbersome to operate, making the existing back-beating devices inconvenient to use and poor in practicality. Utility Model Content

[0005] The purpose of the utility model is to provide an electric back-beating device to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an electric back-beating device, comprising two fixed plates; a movable plate located between the two fixed plates, the movable plate is used to drive the pendulum to move; a pendulum located above the movable plate, the pendulum is used to hit the user's back; two cross bars are bolted between the two fixed plates, one side of one of the cross bars is provided with a screw rod, the screw rod movably penetrates one of the fixed plates, the movable plate is movably penetrated by the screw rod and one of the cross bars, one side of the movable plate is bolted to a second rotating motor, the output end of the second rotating motor is bolted to an eccentric shaft, one end of the eccentric shaft is rotatably connected to a connecting plate, the other end of the connecting plate is bolted to a positioning rod, the positioning rod is bolted to a swing shaft, and the pendulum is located above the swing shaft.

[0007] Preferably, a first rotating motor is bolted to a side of one of the fixed plates away from the movable plate, and the first rotating motor is bolted to the lead screw via a coupling.

[0008] Preferably, two installation grooves are formed at the bottom of the movable plate, a movable block is bolted in one of the installation grooves, and the movable block is threadedly connected to the screw rod.

[0009] Preferably, a bolt connection sleeve is provided in another of the installation grooves, the sleeve is sleeved on the outside of one of the cross bars, and the screw rod is in the same horizontal plane as the cross bar located above.

[0010] Preferably, one end of the connection plate away from the positioning rod is rotatably connected to a transmission rod, and the transmission rod is simultaneously rotatably connected to the eccentric shaft.

[0011] Preferably, the outer part of the positioning rod is bolted to a fixing ring, the bottom part of the swing shaft is bolted to the top part of the fixing ring, and the top part of the swing shaft is bolted to a switching block.

[0012] Preferably, a mounting rod is bolted to the adapter block, a shaking rod is bolted to the top of the mounting rod, and the pendulum is bolted to the top of the shaking rod.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, turn on the second rotating motor to drive the eccentric shaft to rotate, so that the eccentric shaft drives the connecting plate to move through the transmission rod. Since the other end of the connecting plate is connected to the positioning rod bolt, and the positioning rod is rotatably connected to the movable plate, the connecting plate will be driven to swing along the center of the positioning rod when the eccentric shaft rotates. When the eccentric shaft rotates beyond a certain amplitude, it will not continue to drive the transmission rod to rotate, but rotate along the transmission rod itself, so that the connecting rod will only rotate in a circular arc, and then the swing shaft connected to the positioning rod bolt will swing in an arc trajectory, so that the pendulum on the top will swing continuously to make a back-beating action. Multiple components cooperate with each other to achieve the effect of electric back-beating, reduce the steps of manual back-beating for users, save time and effort, and improve the effect of back-beating.

[0015] Second, turn on the first rotating motor to drive the screw to rotate, so that the movable block connected to the screw thread moves outside the screw. Since the movable block is slidingly connected to one of the cross bars through the sleeve at the same time, the movable block will drive the movable plate to slide back and forth along the cross bar when the screw rotates, thereby hitting different parts of the user's back, thereby improving the practicability of the device.

[0022] See also Figure 1-4 , an electric back-beating device, comprising two fixed plates 1; a movable plate 5 located between the two fixed plates 1, the movable plate 5 is used to drive a pendulum 19 to move; a pendulum 19 located above the movable plate 5, the pendulum 19 is used to hit the back of the user; two cross bars 2 are bolted between the two fixed plates 1, one side of one of the cross bars 2 is provided with a screw rod 3, the screw rod 3 movably penetrates one of the fixed plates 1, the movable plate 5 is movably penetrated by the screw rod 3 and one of the cross bars 2, one side of the movable plate 5 is bolted to a second rotating motor 9, the output end of the second rotating motor 9 is bolted to an eccentric shaft 10, one end of the eccentric shaft 10 is rotatably connected to a connecting plate 12, the other end of the connecting plate 12 is bolted to a positioning rod 13, the positioning rod 13 is bolted to a swing shaft 15, the pendulum 19 is located above the swing shaft 15, and the second rotating motor 9 is turned on. The rotating motor 9 drives the eccentric shaft 10 to rotate, so that the eccentric shaft 10 drives the connecting plate 12 to move through the transmission rod 11. Since the other end of the connecting plate 12 is bolted to the positioning rod 13, and the positioning rod 13 is rotatably connected to the movable plate 5, the connecting plate 12 will be driven to swing along the center of the positioning rod 13 when the eccentric shaft 10 rotates. When the eccentric shaft 10 rotates beyond a certain amplitude, it will not continue to drive the transmission rod 11 to rotate, but rotate along the transmission rod 11 by itself, so that the connecting plate 12 will only rotate in a circular arc, and then the swing shaft 15 bolted to the positioning rod 13 will swing in an arc trajectory, so that the pendulum 19 on the top will continuously swing to make a back-beating action. Multiple components cooperate with each other to achieve the effect of electric back-beating, reduce the steps of manual back-beating for users, save time and effort, and improve the effect of back-beating.

[0023] Specifically, a first rotary motor 4 is bolted to one side of one of the fixed plates 1 away from the movable plate 5 , and the first rotary motor 4 is bolted to the lead screw 3 via a coupling.

[0024] Through the above technical solution, the first rotating motor 4 can rotate forward and reverse, thereby driving the screw rod 3 to rotate forward and reverse.

[0025] Specifically, two installation grooves 6 are formed at the bottom of the movable plate 5 , and a movable block 7 is bolted in one of the installation grooves 6 , and the movable block 7 is threadedly connected to the screw rod 3 .

[0026] Through the above technical solution, when the screw rod 3 rotates, it will drive the movable block 7 threadedly connected thereto to translate outside the screw rod 3.

[0027] Specifically, a sleeve 8 is bolted in another mounting groove 6 , and the sleeve 8 is sleeved on the outside of one of the cross bars 2 , and the screw rod 3 and the cross bar 2 located above are in the same horizontal plane.

[0028] Through the above technical solution, the sleeve 8 is used to prevent the screw rod 3 from driving the movable plate 5 to rotate together when rotating.

[0029] Specifically, one end of the connecting plate 12 away from the positioning rod 13 is rotatably connected to the transmission rod 11 , and the transmission rod 11 is rotatably connected to the eccentric shaft 10 at the same time.

[0030] Through the above technical solution, when the transmission rod 11 drives the connecting plate 12 to rotate a certain amplitude, it will be restricted by the position of the positioning rod 13 and will no longer drive the transmission rod 11 to rotate. At this time, the eccentric shaft 10 that continues to rotate will rotate along the center of the transmission rod 11 itself.

[0031] Specifically, the outer portion of the positioning rod 13 is bolted to a fixing ring 14 , the bottom portion of the swing shaft 15 is bolted to the top portion of the fixing ring 14 , and the top portion of the swing shaft 15 is bolted to a transfer block 16 .

[0033] Specifically, a mounting rod 17 is bolted to the adapter block 16 , a shaking rod 18 is bolted to the top of the mounting rod 17 , and a pendulum 19 is bolted to the top of the shaking rod 18 .

[0034] Through the above technical solution, the shaking rod 18 is made of elastic PVC material and has a certain elasticity. When the swing shaft 15 rotates, the inertia of rotation will increase the striking force of the pendulum 19. The pendulum 19 is equipped with a back-beating structure made of silicone material, which will hit the user's back when rotating.

[0035] When in use, the second rotary motor 9 is turned on through the external control terminal, and the output end of the second rotary motor 9 drives the eccentric shaft 10 to rotate, so that the eccentric shaft 10 drives the connecting plate 12 to move through the transmission rod 11. Since the other end of the connecting plate 12 is bolted to the positioning rod 13, and the positioning rod 13 is rotatably connected to the movable plate 5, the connecting plate 12 will be driven to swing along the center of the positioning rod 13 when the eccentric shaft 10 rotates. When the eccentric shaft 10 rotates beyond a certain amplitude, it will not continue to drive the transmission rod 11 to rotate, but will rotate along the transmission rod 11 by itself, so that the connecting plate 12 will only move a certain distance. The first rotating motor 4 is turned on through the external control terminal, and the first rotating motor 4 drives the screw rod 3 to rotate through the coupling, so that the movable block 7 threadedly connected to the screw rod 3 moves outside the screw rod 3. Since the movable block 7 is slidably connected to one of the cross bars 2 through the sleeve 8, the movable block 7 will drive the movable plate 5 to slide back and forth along the cross bar 2 when the screw rod 3 rotates, thereby hitting different parts of the user's back.
