Description
Technical field
The present invention relates to a kind of rocking bar for electric wheelchair.
Background technology
Need in the manufacture process of electric wheelchair the rocking bar for electric wheelchair is installed, rocking bar for electric wheelchair be used for control wheelchair advance and turn to, rocking bar for electric wheelchair is generally positioned in base, 360 degree of rotations in base, do not have position-limit mechanism in the rocker actuator of electric wheelchair in base existing, the rocking bar for electric wheelchair is difficult to the 360 degree of rotations keeping rule, cause rotational trajectory not to be a positive round, affect the control in wheelchair direction like this.In addition, the metal rod ends of magnetic rocking bar is provided with Magnetitum, and Magnetitum must could control wheel chair sport with circuit board generation electromagnetic induction, and in prior art, the outer surface of Magnetitum is naked state, and easy dust stratification, affects electromagnetic induction.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of rocking bar for electric wheelchair, can ensureing that the track of metallic rod when shaking for the rocking bar of electric wheelchair is a positive round, enhancing reliability when direction is rotated, preventing direction diastema.
A kind of rocking bar for electric wheelchair; comprise a base, this base has a square horizontal ends, and being vertical at one-body moldedly below this horizontal ends has first ring body; described first ring body inside is provided with the second annular solid, and the second annular solid inner vertical through this base is provided with a metallic rod; Described second annular solid inside is provided with a holder, and the bottom of described metallic rod is simultaneously through described holder; The bottom of described metallic rod is provided with a ring set, be provided with Magnetitum, and the lower surface of ring set is network structure in this ring set; Be arranged with a tubaeform collar above described metallic rod, the loudspeaker of this collar are opening down; A spring and a retainer ring is provided with successively above the described collar.
Preferably, the two ends of described holder respectively have a projection, and each projection all L-type block be located at on second annular solid contacts; And being provided with two thimbles simultaneously, each thimble contacts described metallic rod through after the second annular solid, L-type block and projection all from first ring body successively externally to interior.When metallic rod is shaken, can ensure that holder just does the very little upset of amplitude, in this programme, the hole that holder allows metallic rod to pass through is designed especially, the two ends in this hole are semicircle, and middle part is rectangle, and this guarantees rocking bar holder when rotation is the very little upset of generation amplitude, owing to being provided with thimble, also limit metallic rod generation diastema phenomenon like this.
Preferably, described holder can overturn in the second annular solid.
Preferably, described base top is also fixed with a rubber ring, and the described lower surface of tubaeform ring set contacts with the upper surface of this rubber ring; This kind of design is also position-limiting action, because ring set is movably set in metallic rod, when shaking metallic rod, the edge of the lower surface edge part branch contact rubber ring of tubaeform ring set, along with the rotation of metallic rod, the lower edge of ring set and the contact point of rubber ring form a positive round, and this positive round is exactly the track that metallic rod rotates; Ring set can move up along metallic rod when metallic rod rotates and simultaneously holddown spring, due to the compression limited extent of spring, the amplitude of rotating with regard to indication metallic rod when spring can not compress further reaches to greatest extent, therefore realizes the position-limiting action that metallic rod is rotated.
Preferably, the top of described metallic rod is also provided with a protective sleeve, and base is located in a cylinder protecting seat.Protective sleeve and protecting seat are all protective effects.
The present invention proposes a kind of rocking bar for electric wheelchair, can ensure that the track of metallic rod when shaking for the rocking bar of electric wheelchair is a positive round, enhance reliability when direction is rotated, limit the rotation amplitude of metallic rod simultaneously, prevent direction diastema and unsceptered.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figures 1 to 4; a kind of rocking bar for electric wheelchair; comprise a base; this base has a square horizontal ends 1; being vertical at one-body moldedly below this horizontal ends 1 has first ring body 2; described first ring body 2 inside is provided with the second annular solid 3, and the second annular solid 3 inner vertical through this base is provided with a metallic rod 4; Described second annular solid 3 inside is provided with a holder 5, and the bottom of described metallic rod 4 is simultaneously through described holder 5; The bottom of described metallic rod 4 is provided with a ring set 6, be provided with Magnetitum 7, and the lower surface of ring set 6 is network structure in this ring set 6; Be arranged with a tubaeform collar 8 above described metallic rod 4, the loudspeaker of this collar 8 are opening down; Spring 9 and a retainer ring 10 is provided with successively above the described collar 8.
The two ends of described holder 5 respectively have a projection 11, each protruding 11 all the L-type block 12 be located at on second annular solid 3 contact; And being provided with two thimbles 13 simultaneously, each thimble 13 contacts described metallic rod 4 through after the second annular solid 3, L-type block 12 and protruding 11 all from first ring body 2 successively externally to interior.When metallic rod 4 is shaken, can ensure that holder 5 just does the very little upset of amplitude, in this programme, the hole that holder 5 allows metallic rod 4 to pass through is designed especially, the two ends in this hole are semicircle, and middle part is rectangle, and this guarantees rocking bar holder 5 when rotation is the very little upset of generation amplitude, owing to being provided with thimble 13, also limit metallic rod 4 like this and diastema phenomenon occurs.
Described holder 5 can overturn in the second annular solid 3.
Described base top is also fixed with a rubber ring 14, and the lower surface of described tubaeform ring set 6 contacts with the upper surface of this rubber ring 14; This kind of design is also position-limiting action, because ring set 6 is movably set in metallic rod 4, when shaking metallic rod 4, the edge of the lower surface edge part branch contact rubber ring 14 of tubaeform ring set 6, along with the rotation of metallic rod 4, the lower edge of ring set 6 and the contact point of rubber ring 14 form a positive round, and this positive round is exactly the track that metallic rod 4 rotates; Ring set 6 can move up along metallic rod 4 when metallic rod 4 rotates and simultaneously holddown spring 9, due to the compression limited extent of spring 9, the amplitude of rotating with regard to indication metallic rod 4 when spring 9 can not compress further reaches to greatest extent, therefore realizes the position-limiting action that metallic rod 4 is rotated.
The top of described metallic rod 4 is also provided with a protective sleeve 15, and base is located in a cylinder protecting seat 16.Protective sleeve 15 and protecting seat 16 are all protective effects.The top of metallic rod 4 is also provided with hands 17, and when use, people holds hands 17.
The present invention proposes a kind of rocking bar for electric wheelchair, can ensure that the track of metallic rod when shaking for the rocking bar of electric wheelchair is a positive round, enhance reliability when direction is rotated, limit the rotation amplitude of metallic rod simultaneously, prevent direction diastema and unsceptered.
Above-described is only the preferred implementation of a kind of rocking bar for electric wheelchair provided by the present invention; should be understood that; for the person of ordinary skill of the art; without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
