Description
Technical field
The present invention relates to spring-grip, especially relate to the spring-grip of a kind of adjustable grip strength and grip scope.
Background technology
Traditional spring-grip is a main spring structure or bar linkage structure, due to simple in structure, cannot flexible modulation grip strength or change grip scope, thereby cannot be adapted to the demand of different people.
Chinese patent CN200920179861.5 provides a kind of strength adjustable spring-grip, comprises the first lever, the second lever and a connecting rod.Wherein, the mutual pivot joint in top of the top of the first lever and the second lever, the inner side of the first lever is provided with an elastic component, the second lever is provided with a regulating part corresponding to a side of the first lever inner side, and the two ends of connecting rod link respectively elastic component and regulating part, by regulating part adjustable elastic part, thereby reach the object of adjusting grip strength.
Chinese patent CN200880104609.6 provides a kind of spring-grip, comprising: first and second motion arm, sow discord mutually configuration; First and second pitman arm, be configured in obliquely successively between described first and second motion arm, and each two ends is rotated respectively and is connected to freely described 2 motion arms by rotating shaft; Spring members, is set to hindering described the first motion arm and the close direction of the second motion arm that elastic force is provided.
Above-mentioned patent is that basic component or double operation handle pivot joint are that basic component forms by single main spring, and without grip range regulation function.
Summary of the invention
The object of the invention is to the above-mentioned shortcoming existing for traditional spring-grip, the spring-grip of a kind of adjustable grip strength and grip scope is provided.
The present invention is provided with box body, left guide rod, right guide rod, left Compress Spring, right Compress Spring, upper padding plate, lower bolster, lower shaft, upper left axle, upper right axle, holding rod, upper left tune power nut, upper right tune power nut and the power of downward nut;
Described left guide rod is parallel with right guide rod to be located in box body, the two ends of left guide rod and right guide rod are respectively through upper padding plate and lower bolster, left Compress Spring is enclosed within on left guide rod, left Compress Spring and right Compress Spring are between upper padding plate and lower bolster, lower shaft passes lower bolster and is fixed on the bottom of box body, downward power nut sleeve is on lower shaft and be positioned at lower bolster bottom, upper left axle passes respectively the top of upper padding plate and box body and is connected with the bottom of holding rod with upper right axle, and upper left adjusts power nut and upper left to adjust power nut to be enclosed within respectively on upper left axle and upper right axle.
The present invention adopts a box structure, includes grip and trains required Compress Spring and force-regulating device and rackwork.Force-regulating device utilizes spring deformation principle, changes the initial intensity of force of holding by the deformation quantity that changes spring, makes strength building be applicable to the operator that grip is different.Rackwork, by adjusting grip scope, makes it be applicable to the trainer that hand-type varies in size.
The present invention is by one-handed performance, for tempering the small body-building apparatus of grip.Traditional spring-grip is a main spring structure or bar linkage structure, due to simple in structure, cannot flexible modulation grip strength or change grip scope, thereby cannot be adapted to the demand of different people, as larger or less in some people's grip, some people's palm is larger or less.The adjustable grip strength of the present invention and grip scope, by the different innovative design of structure, increase grip strength adjusting device, utilize spring deformation principle, the size that changes initial grip by changing the deformation quantity of spring, makes strength building be applicable to the operator that grip is different.Meanwhile, increase grip range regulation device, made it be applicable to the operator that hand-type varies in size.
The present invention adopts box structure, and its inner passing through regulates lower nut, makes lower bolster along lifting on lower shaft or declining, and the spring of being guided by guide rod between compression or release lower bolster and upper padding plate, holds holding rod and box body when operation, thereby makes grip become greatly or diminish.By the adjusting nut of transposing, can make holding rod raise or reduce, thereby change grip scope, be applicable to the different grip trainer of hand-type.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the embodiment of the present invention.
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.
The specific embodiment
The present invention is further illustrated in connection with accompanying drawing for following examples.
Referring to Fig. 1 and 2, the embodiment of the present invention is provided with box body 1, left guide rod 21, right guide rod 22, left Compress Spring 31, right Compress Spring 32, upper padding plate 41, lower bolster 42, lower shaft 51, upper left axle 52, upper right axle 53, holding rod 6, upper left tune power nut B1, upper right tune power nut B2 and the power of downward nut A.Described left guide rod 21 is parallel with right guide rod 22 to be located in box body 1, the two ends of left guide rod 21 and right guide rod 22 are respectively through upper padding plate 41 and lower bolster 42, left Compress Spring 31 is enclosed within on left guide rod 21, left Compress Spring 31 and right Compress Spring 32 are between upper padding plate 41 and lower bolster 42, lower shaft 51 passes lower bolster 42 and is fixed on the bottom of box body 1, downward power nut A is enclosed within on lower shaft 51 and is positioned at lower bolster 42 bottoms, upper left axle 52 is connected with the top of box body 1 and with the bottom of holding rod 6 through upper padding plate 41 respectively with upper right axle 53, upper left adjusts power nut B1 and upper left to adjust power nut B2 to be enclosed within respectively on upper left axle 52 and upper right axle 53.
