The utility model has the advantages that: the utility model discloses a reliable many wheel structures of stable in structure can switch to the wheel of required function according to the operational environment demand of difference, can satisfy operational environment's user demand and can increase of service life again, also can regard as universal wheel or directive wheel to use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention;
fig. 2 is an exploded view of the present invention;
fig. 3 is a schematic structural diagram of the connection seat of the present invention.
Detailed Description
Referring to fig. 1 to 3, a caster wheel capable of switching wheels comprises a connecting seat 4, wherein the connecting seat 4 is rotatably connected with a conversion support 3, the rotatable connection effect can be realized by rivets, the connecting seat 4 is provided with a positioning device 1 capable of fixing the conversion support 3, the positioning device 1 can be a pin sleeve, a bolt type movable positioning pin connected with a handle of the movable pin is arranged on the inside, a pin sleeve is arranged on the outside, at the back, the pin type movable positioning pin is connected with at least two wheels with different functions, the conversion support 3 is provided with a positioning structure 301 corresponding to each wheel, for example, the wheels with different functions can adopt two wheels, namely a soft wheel and a hard wheel.
The conversion bracket 3 is an axisymmetric L-shaped object, and two tail ends of the conversion bracket are respectively connected with wheels with different functions in a rotating way. One end of the L-shaped object is vertically downward, so that the bearing capacity is higher, the plane of the other end is abutted to the connecting seat 4, the limiting effect is achieved, and the structure of the caster is more stable and reliable. In this embodiment, the two tail ends of the conversion bracket are respectively and rotatably connected with the soft wheel and the hard wheel, and when the bicycle runs in an environment with an anti-scratch ground or a mute requirement, the soft wheel can be switched to use; when the switchable hard wheel is used in some environments without using requirements on the wheel, the load-bearing capacity is strong, the wheel is resistant to abrasion and has long service life.
The positioning device 1 mainly comprises a screw and a nut, the positioning structure 301 is a circular arc-shaped long round hole, the connecting seat 4 is provided with a through hole corresponding to the long round hole, and the long round hole and the through hole are locked and fixed through the screw and the nut, so that more angles can be fixed by the conversion support 3, and the purpose of adjusting the height of the caster wheel is achieved.
The universal wheel is characterized by further comprising a fixed seat 2, wherein a circular cavity is formed in the lower portion of the fixed seat 2, a sleeve-shaped object 403 matched with the cavity is arranged on the upper portion of the connecting seat 4, and the sleeve-shaped object 403 is rotatably inserted into the cavity, so that the universal wheel can be used in the embodiment.
The sleeve-shaped object 403 is provided with a first orientation hole 401 penetrating through, the fixing base 2 is provided with a second orientation hole 201 corresponding to the first orientation hole 401, the first orientation hole 401 and the second orientation hole 201 are provided with a positioning screw 5 for limiting the relative rotation of the fixing base 2 and the connecting base 4, when the positioning screw 5 is locked, the embodiment can be used as an orientation wheel, and when the positioning screw 5 is removed, the embodiment can be used as a universal wheel.
The lower part of fixing base 2 is equipped with the circular arc groove, connecting seat 4 is equipped with the lower circular arc groove 402 corresponding with last circular arc groove, be equipped with a plurality of steel balls between last circular arc groove and the lower circular arc groove 402, turn to when this embodiment uses as the universal wheel more in the same direction as smooth, laborsaving and improved life.
