Description
Technical field
The utility model relates to a kind of grabbing device, more specifically relates to a kind of grabbing device of six-bar mechanism.Be applicable to and take and place some daily living article apart from the health certain distance, the auxiliary independent living ability of realizing this group of handicapped.
Background technology
At present, State Intellectual Property Office of the People's Republic of China looks into the utility model of not having approximate this type, does not also see similar products like on the domestic market.The external similar products like function singleness that seems, implementation is complicated, can not well be fit to the needed hommization of group of handicapped and operate requirement.
Calculate that according to for the second time national disabled person's sample investigation data in 2006 national all kinds of disabled persons add up to 8,296 ten thousand people, with for the first time national disabled person's sample investigation in 1987 relatively, China disabled population total amount increases, disabled person's ratio rises.The ratio that China disabled person accounts for country's total population is 6.34%, and wherein physical disabilities 2,412 ten thousand people account for 29.07% maximum ratio.Whole nation Eleventh-Five Year Plan outline also with disabled person's problem as emphasis, as seen be concerned about the disabled person employment, be concerned about that disabled person's life seems particularly important, this also is the importance of building a harmonious society.
Along with the overall growth in the living standard of the people, disabled person's quality of life also will improve thereupon.The utility model designs for convenience of disabled person's daily life just, fills up the blank of domestic market, has had similar products like to prove that also the utility model will have very big practical value and market prospects abroad.
Summary of the invention
The purpose of this utility model is to provide a kind of grabbing device of helping the disabled based on six-bar mechanism, this device is the utensil of helping the disabled that lower limb disability wheelchair person or a handicapped class crowd (especially old crowd) provide convenience to grasp article, the function that realizes taking and place the slight small item product outside the distance of stretching out one's hand.
In order to achieve the above object, the utility model adopts following technical measures:
The utility model is made up of clamping device part, twist mechanism part, telescoping mechanism part, handle portion, bracket portion.The clamping device part is made up of movable supporting rod and fixed clamp bar two parts, the steel wire brake cable changes grip into pulling force, make movable supporting rod rotating counterclockwise around the fixed clamp bar, realized the clamping function of clamping device part, the back-moving spring of movable supporting rod and interconnection place of fixed clamp bar has then been realized the loose Zhang Gongneng of clamping device part.The fixed clamp bar is slidingly connected by connecting rod and abutment sleeve, wherein the fixed clamp bar rigidly fixes by screw with connecting rod and is connected, connecting rod can be by the angle of the U type groove half-twist in sleeve on the abutment sleeve, and by the location of the pin on the connecting rod, this part is exactly a twist mechanism part of the present utility model.The telescoping mechanism part is made up of by the hinged mode of bearing pin the rod member that six roots of sensation length has nothing in common with each other, and wherein drive rod rigidly fixes with preceding belt shaft and is connected, so rotatablely moving of synchronous pulley just can be converted into the stretching motion of six-bar mechanism.Handle directly is connected with empty the overlapping of band bar synchronously, in order to adapt to different users's requirement, needs the position of handle on bar can relative adjustment, so the utility model designed breach in the handle bottom, connects by bolt and locks, and reaches the purpose of location.Be connected a steel wire brake cable between the movable supporting rod of handle flexible handle and clamping device, this brake cable has been realized the transmission of power just, has reached the singlehanded controlled purpose of clamping device.During use, the forked type carriage of bracket portion and people's upper arm relative fixed, when the people holds the telescopic handle arm, according to ergonomics as can be known the angle between forearm and the big arm variation has necessarily taken place, the information that angle changes will equal proportion passed to and the rigidly connected back of forked type frame belt shaft, flexible nature by synchronous band, the information that angle changes further passes to the preceding belt wheel that becomes vertical orientations with the back belt wheel, reach the purpose that drives drive rod in the telescoping mechanism part, realized the extension and contraction control of six-bar mechanism.Its annexation is: movable supporting rod is connected by the axle of having strong market potential with the fixed clamp bar, the fixed clamp bar is fixedlyed connected with front rod, back-moving spring one end is fixedlyed connected with movable supporting rod, the other end is fixedlyed connected with front rod, the abutment sleeve sky is enclosed within on the front rod, preceding quarter butt is connected with abutment sleeve, preceding quarter butt is connected by preceding major axis with preceding stock, preceding stock is connected by middle minor axis with the back stock, be connected by middle major axis with bridging bar, back stock is connected by preceding belt shaft with drive rod, be with and preceding belt shaft synchronously, back belt shaft is meshed, be strained and fixed in the inside of synchronous band bar, the locus of preceding belt shaft and back belt shaft is vertical, drive rod is connected by the back minor axis with rear connecting rod, rear connecting rod is connected by short pin shaft with bridging bar, be connected by preceding minor axis with preceding quarter butt, branch sleeve one end is fixedlyed connected by screw with the back stock is terminal, the other end is fixed on the synchronous band bar by screw, handle is fixed on the synchronous band bar with clamping screw, is with terminal the overlapping with the bracket sleeve sky of bar to be connected synchronously, fixes by screw, the fork-shaped carriage is fixedlyed connected by two pins with the back belt shaft, and back belt shaft is connected with the empty cover of bracket sleeve.
The utility model has imitated people's arm on implementation, carried out the selection of design from the angle of hommization.Domestic still do not have this type of utility model, do not have this series products on the market especially, and therefore advantage of the present utility model seems particularly outstanding:
1, the execution architecture of retained part is simple and practical, reliability is high, does not need special maintenance.Supporting rod is designed to special shape, has adopted the structure not of uniform size of turning round of 3 shown in the figure one, has adapted to the demands of the different big wisps of gripping.
2, the design of the U type groove on the abutment sleeve has realized that the clamp structure part changes and the location self-locking with vertical and the relative position of being with bar synchronously in the horizontal direction.
3, the position relatively adjustable particular requirement that realize different users of handle portion on synchronous band bar, the radian parameter that staff is held with a firm grip and pinched fist in the arc ergonomic design of movable handgrip, the comfort level when having guaranteed to use.
4, utilized the flexible nature of synchronous band, realized the transmission of alternating axis, made and to realize the angle information propagation function between two synchronous pulleys of perpendicular positioning.
No matter 5, the design of forked type carriage has guaranteed what orientation arm is in and can both be limited fully, and the use of this kind designing material is few, lightweight construction has really been considered group of handicapped's instructions for use.
