Abstract
The utility model relates to a boxing force measurer, which is composed of a flexible force bearing body, a drive mechanism and an indicator which comprises a scale plate and a pointer. The drive mechanism is composed of a drive shaft, a sleeve barrel, a spring and a connection rod. The outer part of the drive shaft is externally connected with the flexible force bearing body. The utility model is a fully mechanical structure, and has the advantages of simple structure, easy manufacture and low cost.
Description
This usefulness is novel to relate to a kind of boxing dynamometer, belongs to the body-building apparatus field.
Mostly the apparatus of dynamometry of being used at present to box is that electron number is explicit, a kind of " electronic digital display shadowbox device " disclosed as Chinese patent CN2169453, comprise that being hit body, dynamometer link, tachogenerator and digital display device forms, this training aids can accurately be measured the boxing dynamics, but it has utilized complicated electronic sensor and display circuit, and structure is complicated, makes and maintenance difficult, cost is higher, is unfavorable for spreading to society and family.
The utility model is the deficiency at above-mentioned prior art existence, and a kind of boxing dynamometer of full mechanical is provided, and is simple in structure, is easy to make and maintenance, and cost is low, helps general family and individual's popularization and application.
The utility model comprises flexible beaer, transmission mechanism and display, display is made up of pointer and scale plate, pointer is supported by soft spring, be fixed on the scale plate with screw, transmission mechanism is by power transmission shaft, sleeve, spacing hollow spiral shell, spring, pin and connecting rod are formed, sleeve one end is fixed on the scale plate, the other end connects spacing hollow spiral shell, interior looper drive shaft and spring, the spring that power transmission shaft one end overcoat one end is fixing, the other end is stretched out by hollow threaded bore, and the part that the power transmission shaft stage casing is positioned at sleeve is slidingly matched with sleeve, and its diameter is greater than the aperture of spacing hollow spiral shell.Power transmission shaft is provided with by the fixing key pin of fastening key, and power transmission shaft is slided along the chute on the sleeve; Connecting rod is supported by soft spring, be fixed on the sleeve with screw, connecting rod one end extends the pointer lower end, when pointer is in zero-bit, with end in contact under the pointer, the other end of connecting rod closes with the pin cunning with the key pin of power transmission shaft and is connected, and the other end of connecting rod closes with the pin cunning with the key pin of power transmission shaft and is connected, and plays gearing.Flexible beaer is connected with power transmission shaft.
Describe the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model display device structure figure.
The utility model is made up of flexible beaer, transmission mechanism and display, and as depicted in figs. 1 and 2, display comprises scale plate 1 and pointer 17, and pointer is supported by soft spring 19 and is fixed on the scale plate with screw 16, is provided with packing ring 18 between soft spring 19 and the pointer 17.Transmission mechanism comprises power transmission shaft 6, sleeve 2, spring 3 and connecting rod 14, one end of sleeve 2 is fixed on the scale plate 1, the other end connects a spacing hollow spiral shell 5, looper drive shaft 6 and spring 3 in the sleeve 2, the spring 3 that power transmission shaft 6 one end overcoats one end is fixing, the other end is stretched out by spacing hollow spiral shell 5 holes, connects flexible beaer 10.The part that power transmission shaft 6 stage casings are positioned at sleeve 2 is slidingly matched with sleeve, and this section diameter is greater than spacing hollow spiral shell 5 apertures.Make spring 3 when not stressing state, power transmission shaft 6 these sections just slightly contact with spacing hollow spiral shell 5 the inners.The design of looper drive shaft 6 one ends is in order to limit power transmission shaft and spring position, to make impulsive force not be subjected to loss, accurately being showed by pointer in spacing hollow spiral shell 5 and the spring 3.Power transmission shaft 6 is provided with key pin 4, is fixed by fastening key 15, is used for drivening rod 14 motions, and when power transmission shaft 6 slided in sleeve 2, it slided along the chute of sleeve 2, is used to limit power transmission shaft 6 unlikely rotations.Connecting rod 14 is supported by soft spring 20 and is fixed on the sleeve 2 by screw 12, is provided with packing ring 13 between soft spring 20 and the connecting rod 14.Key pin 4 on one end of connecting rod 14 and the power transmission shaft 6 is connected by pin 11 sliding closing, and the other end extends pointer 17 lower ends of display, when its position is in zero-bit at pointer 17, corrects for 17 times with pointer and to contact.Flexible beaer 10 is formed by base plate 9 outsourcing flexible material layers 7, and is fixing by screw 8, and base plate 9 adopts spiral to be connected with power transmission shaft 6.
Scale on the utility model display is to determine according to the spring pressure.For the ease of the clear value of reading of user, pointer of the present utility model adopts hand-reset.
The course of work of the present utility model is when flexible beaer receives the strength impact, promotes power transmission shaft and slides rapidly along sleeve, and the power transmission shaft pressuring spring, key pin is by the swing of pin drivening rod on the axle during power transmission shaft displacement, and connecting rod touches pointer, and the power value is hit in indication.The size of impulsive force, the decision power transmission shaft is to the size of spring pressure, and the amplitude of fluctuation size of connecting rod, and corresponding decision connecting rod accurately shows and hits the power value the length of the shake-up distance of pointer.
The utility model is a kind of fully mechanical structure, and is simple in structure, is easy to make.Also be convenient to repair, cost is low, is suitable for spreading to family and individual.
