Abstract

The utility model relates to a device for body building. A guide rail which can be used for a machine body to slide is arranged on a machine frame of an automatic back hammering machine. A hammering arm is connected with the machine body by a shaft; a motor, a worm which is driven by the motor and a reduction gear are arranged on the machine body. A plurality of shifting pins are uniformly distributed on a worm wheel, a crank which is used for shifting discontinuously for the shifting pins and a spring are arranged on the tail of the hammering arm, and the automatic telescopic mechanism of the hammering arm which is driven by the crank is arranged on the hammering arm; an automatic sliding mechanism which is driven by the reduction gear is arranged on the machine body, and the automatic sliding mechanism can slide from the front to back of the machine body. The utility model has the advantage of novel design, all points of backs of users can be hammered automatically by using the utility model, and tired symptoms can be eliminated.

Description

Automatic beating back machine

This utility model relates to body-building equipment, is a kind of automatic beating back machine that can impel people to eliminate fatigue symptoms such as aching all over rapidly.

Along with social progress, people's life and work is also more nervous, and fatigue in a day is got off, brain worker especially, and the body-building equipment of fatigue symptom such as wishes all to have that a kind of rapid elimination is ached all over, generally the old man also has this requirement.The purpose of this utility model provides a kind of automatic beating back machine, and it can be beaten people's back, and moves the back that spreads all over the people while beating, and plays relaxing muscles and tendons to promote blood circulation, relaxs one's muscles, the effect of allaying tiredness.

The purpose of this utility model is to realize like this, automatically the beating back machine frame is provided with the guide rail for sliding machine body, hammerhead jib is connected on the fuselage by axle, fuselage is provided with motor and by the worm screw and the reduction gearing of motor transmission, be evenly equipped with several fingers on the worm geared worm gear, the afterbody of hammerhead jib also is provided with the automatic telescoping mechanism of the hammerhead jib that is subjected to the crank-operated transmission for being interrupted crank and the spring of stirring for finger on the hammerhead jib, fuselage is provided with the automatic coasting mechanism in fuselage front and back that is subjected to the reduction gearing transmission; The automatic telescoping mechanism of hammerhead jib comprises stepping wheel, connecting rod and push-pull bar, and stepping wheel is subjected to crank gearing, crank-operated once, it turns an angle, connecting rod connects stepping wheel and push-pull bar, push-pull bar is handled the glue hammer expanding-contracting action on the hammerhead jib; Automatic coasting mechanism comprises before and after the fuselage:

(1) drive [17], [18]: drive [17] is the son wheel of reduction gearing, is the friction transmission between [17], [18] two-wheeled.

(2) front driving wheel, break-in wheel, rear drive sprocket: they slide the rear drive of drive elder generation before and after finishing fuselage.

(3) orientation lever and spring thereof: the orientation lever axis is coaxial with drive [18], and it makes drive [18] can swing the location.

(4) break-in cross bar: be fixed on the axle of drive [18], when fuselage slided into front end or rear end, frame was handled it and is made drive [18] swing transposition.

Characteristics of the present utility model are: modern design, can eliminate fatigue symptom such as ache all over rapidly.

Figure below example in conjunction with the accompanying drawings further describes.Fig. 1 is this utility model structural principle sketch map, and Fig. 2 is this utility model plan structure sketch map, and Fig. 3 is for sliding the automatic reverse principle schematic before and after this utility model fuselage.

Embodiment: referring to Fig. 1,2,3, be application example of the present utility model, glue hammer [16] is that rubber is made, and the friction wheel surface is provided with rubber layer, the department of electrical engineering outsourcing piece, and all the other each parts are made by high-quality plastics.Narrate this motor-driven work now in conjunction with the accompanying drawings, referring to Fig. 1, when motor [6] rotates, worm screw [7] drives worm gear [9] and rotates, and finger [10] presses crank [11] and spring [12] makes hammerhead jib [4] rotate around axle [5], and glue hammer [16] lifts, after finger [10] got around crank, spring was upheld glue and is beaten next time.Present narration hammerhead jib expanding-contracting action, whenever crank [11] action once, stepping wheel [13] rotation 45 degree, connecting rod [14] drives position of push rod [15] conversion, crank-operated eight times, and the stepping wheel rotates a week, hammerhead jib is finished the expanding-contracting action of a glue hammer [15], referring to Fig. 2.Narration fuselage [2] is gone up the action that slide automatic front and back at the guide rail [3] of frame [1] now, referring to Fig. 2, Fig. 3, when motor rotates, reduction gearing [8] action, by drive [17] friction drive [18], drive front driving wheel [19], fuselage [2] slides on frame [1], when sliding into the frame front end, frame is blocked break-in cross bar [23], makes locating rod and spring [22] be indexed to opposite side, and drive [18] is so drive break-in wheel [20], rear drive sprocket [21] slides backward fuselage on frame, when fuselage slides into frame rear end, the break-in bar moves again, and fuselage break-in again slides, go round and begin again like this, slide front and back voluntarily.Narrate the using method of this automatic beating back machine now, user is essential in bed prostrate, this machine is placed on the bedside with eminence, at this moment hammerhead jib is stretched above user, connect motor, fuselage is front and back slip on one side just, and hammerhead jib is just flexible on one side, and the pounding one's back downwards of fixed time interval, the range of activity of hammer spreads all over the full back of the body.Adjust the hammerhead jib original position, can adjust the dynamics of pounding one's back; Adjust the link position of connecting rod, just can adjust the flexible scope of hammerhead jib at the stepping wheel; Break-in cross bar block is set on the frame, then can limits and change the fuselage front and back and slide scope.
