Description

A kind of damping is adjustable grip device for healing and training

Technical field

The utility model relates to device for healing and training, the adjustable grip device for healing and training of especially a kind of damping.

Background technology

Early stage spring-grip is to produce the damping force of resisting grip by flexible member to realize the training of hand grip.Along with popularizing of body building, the equipment that carries out the grip training begins prosperity and development.At present, the spring-grip product that has also occurred some adjustable resistance on market.These adjustable damping spring-grips mainly are adjusted to principal mode with Purely mechanical, are generally by the quantity that changes flexible member or the generation that the moment loading point is realized different damping moment.Its advantage is simple in structure, and cost is low.Shortcoming is that variable torque divides some grades of levels, can not be adjustable continuously, and torque accuracy is relatively poor, can't satisfy the particular demands of the rehabilitation training of specific crowd, as the rehabilitation training of Patients with Apoplexy Sequela.

For these reasons, be necessary to design a requirement that can satisfy the rehabilitation training of specific crowd, also can take into account the Novel pressure relief trainer that general population's body-building needs.This device had both kept traditional spring-grip compact conformation, lower-cost characteristics, also can realize the adjustable arbitrarily continuously of damping torque, after installing the auxiliary electron circuit additional, also can realize Auto-counting, demonstration and zero clearing, also can show current damping torque value, and possess and the functions such as other intelligent electronic device the transmission of data, thereby satisfy the user demand of specific crowd.

The utility model content

The spring-grip that the purpose of this utility model is to overcome prior art can't be realized the technical problem of continuous Torque-adjusting, provides a kind of novel damping continuously adjustable grip device for healing and training.

For realizing above purpose, the utility model has been taked following technical scheme: a kind of damping is adjustable grip device for healing and training, comprise interconnective left handle and right handles, left handle and right handles junction are the articulated section, be provided with the symmetrical solenoid group of many groups in the articulated section, the solenoid group comprises magnetic core and is looped around the solenoid of magnetic core periphery, is provided with magnetorheological liquid bath between adjacent solenoid group; Also be provided with the connection electric lead in described left handle or right handles, described connection electric lead one end is connected with the solenoid group by contact switch, and the other end is connected with the damping torque setting device in the external world.

Several solenoids with magnetic core that this device utilizes foreign current to control in the grip handle that nonmagnetic substance makes produce magnetic fields, but the magnetic flow liquid in the magnetorheological liquid bath in control coil both sides, magnetic field is converted into Bingham fluid from Newtonian fluid, thereby forms damping torque.The size of damping torque determines (also namely being determined by current strength in coil) by magnetic field intensity.Whether switch on or control size of current or the above-mentioned dual mode of its mixing use by controlling one or more groups coil, realizing the adjustable continuously of damping torque.

The utility model utilizes the solenoid controlled magnetic flow liquid to produce the damping torque of shear direction, and is applied on the grip device.Adopt simultaneously the plurality of electromagnetic coil groups to control, by the working quantity of change solenoid group or current strength or the combinations thereof mode of coil, realize the setting of damping torque magnitude range, and continuous fine adjustment.

The utility model compared with prior art has following advantage: this device adopts nontoxic, and free of contamination magnetic flow liquid utilizes DC power control damping size as the variable resistance medium, and control mode and adjustment are very simple and convenient.Simultaneously, product with compact structure is made simple.Only need to increase the auxiliary electron circuit and just can realize the various value-added functionalitys such as Auto-counting, demonstration, zero clearing, satisfied the various demands of different crowd, market prospects are bright.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.

Embodiment:

See also Fig. 1 to shown in Figure 4, a kind of damping is adjustable grip device for healing and training, comprise interconnective left handle 1 and right handles 2, the junction of left handle 1 and right handles 2 one ends is articulated section 3, be provided with the symmetrical solenoid group 4 of many groups in articulated section 3, in Fig. 1 take center of circle symmetry as four groups of solenoid groups, also can be two groups or eight groups of solenoid groups, decide according to actual conditions); Solenoid group 4 comprises magnetic core 41 and is looped around the solenoid 42 of magnetic core 41 peripheries, is provided with magnetorheological liquid bath 5 between adjacent solenoid group 4; Also be provided with leftward connection electric lead 6 in handle 1 or right handles 2, connect electric lead 6 one ends and be connected with solenoid group 4 by contact switch 8, the other end is connected with the damping torque setting device 7 in the external world.

The course of work of the present embodiment is: at first, can be realized by computer control special purpose interface plate by this device of damping torque setting device 7(, it is common general A/D switch technology, can utilize the drag size numerical transformation of computer software setting by the user by this technology is corresponding size of current) certain predetermined grip value is set, the electric current that 7 outputs of damping torque setting device meet the demands inputs on some solenoid groups 4 by connecting electric lead 6, make solenoid 42 produce magnetic field, the grip device is in the duty that damping is arranged; When the grip device is held to limit, contact switch 8 closures on grip device left handle 1, disconnecting positive wire can cut off the electricity supply, cut off electric current, damping disappears, and after unclamping the left and right handle, handle is expanded to original state under the effect of the returning spring of articulated section 3.And so forth, can realize the grip training.
