Specific embodiment

The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model, It states.The preferred embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms in fact It is existing, however it is not limited to embodiment described herein.On the contrary, purpose of providing these embodiments is makes public affairs to the utility model The understanding for opening content is more thorough and comprehensive.It should be noted that unless otherwise specific defined restriction, term " installation ", " phase Even ", the terms such as " connection ", " fixation " shall be understood in a broad sense, for example, connection may be a fixed connection, be also possible to detachably connect It connects, can be directly connected, be also possible to the connection being also possible in two elements indirectly connected through an intermediary.For For those skilled in the art, can understand as the case may be above-mentioned term in the present invention specifically contain Justice.

It is described in detail below in conjunction with roller structure of the attached drawing for the utility model.

As shown in Fig. 1~7, roller structure 100, including pedestal 10, be sheathed on pedestal 10 and with pedestal 10 be fitting to connection Package assembly 30 is fitting to connection the first capping 50 and fitting connection in 30 the same end of pedestal 10 and package assembly in pedestal 10 and housing Second capping 70 of the identical other end of part 30.First capping 50 and the second capping 70 are usually symmetrical structure, are fitted into simultaneously respectively In two identical ends of pedestal 10 and package assembly 30.Roller structure 100 generally passes through driving device (not shown) It is driven, driving device connects pedestal 10 when driving device operates by shaft (not shown) and driven by shaft Pedestal 10 rotates, and be fitting to connection with pedestal 10 first the 50, second capping 70 of capping and package assembly 30 is driven to rotate together.

As shown in figure 3 to figure 7, pedestal 10 has body part 11, and multiple first lug boss, 15 Hes are arranged in the edge of body part 11 Multiple first concave parts 16, multiple first lug bosses 15 and multiple first concave parts 16 are arranged in a crossed manner, and body part 11, which is equipped with, to be run through Hole 13, the middle part of body part 11 are equipped with the connecting hole 12 worn for shaft, are equipped with around connecting hole 12 for idler wheel 100 and outer The mounting hole 14 that boundary's component is installed.

Continue as shown in figure 3 to figure 7, the first capping 50 is equipped with the first extension being fitting to connection with one end of through hole 13 53, the second capping 70 is equipped with the second extension 73 being fitting to connection with the other end of through hole 13.First capping 50 passes through first The through hole 13 of extension 53 and body part 11 is cooperated and is fitting to connection, and the second capping 70 passes through the second extension 73 and this The through hole 13 in body portion 11 cooperated and is fitting to connection, thus improves the first capping 50, second capping 70 and pedestal 10 Connect fixing.Also, the middle part of the first capping 50 is equipped with the first through hole 51 coaxial with connecting hole 12, and second covers in 70 Portion is equipped with second through-hole 71 coaxial with connecting hole 12.

Continue as shown in figure 3 to figure 7, package assembly 30 is equipped with the cooperation of multiple and the first lug boss 15 towards the side of pedestal 10 Second concave part 33 and multiple the second lug bosses 31 with the cooperation of the first concave part 16, pedestal 10 and package assembly 30 are by thereon The concave part and lug boss being equipped with are cooperated and are fitting to connection, thus improve the jail of the connection between pedestal 10 and package assembly 30 By property.First lug boss 15 or the second lug boss 31 are half elliptic in the projection of shape of the first capping 50, and projection of shape is half The lug boss of ellipse can be easier to realize during processing with concave part and be fitting to connection.The both ends of package assembly 30 are set respectively There are the first notch 35 and the second notch (not shown), the first notch and the second notch are symmetrical structure, and the first capping 50 is embedding The one end for being connected to the first notch 35 and being overlapped in the second lug boss 31 is closed, the second capping 70 is fitting to connection in the second notch and takes It is connected to the other end of the second lug boss 31.Package assembly 30 is fitting to connection with pedestal 10, the first capping 50 and the second capping 70 Also be fitting to connection with pedestal 10, then it is chimeric by the first capping 50 and the second capping 70 and be overlapped in package assembly 30 can make it is outer External member 30, pedestal 10 and capping are closerly chimeric, and the more compact structure of idler wheel, volume are smaller.Package assembly 30 is far from pedestal 10 side is equipped with multiple gear teeth 37 and multiple tooth sockets 39 with 37 cross arrangement of the gear teeth.Two ends of multiple gear teeth 37 all to Middle part inclination, impacts the rolling of roller structure 100, the gear teeth 37 to avoid the end of the gear teeth 37 there are sharp corner angle In first capping 50 projection of shape be it is trapezoidal, the setting of the trapezoidal gear teeth 37 can weaken the sharpness of the gear teeth 37.

It should be noted that the roller structure of the utility model can also be magnetic part, such as by pedestal 10 or package assembly 30 By magnetic material be made or pedestal 10 inside be equipped with magnetic stripe or magnetic patch and obtain a kind of magnetic roller structure.Because of magnetism Setting not for the utility model application emphasis, so it will not be repeated.

It should be pointed out that the above specific embodiment is merely to illustrate the utility model rather than limits the utility model Range, after having read the utility model, those skilled in the art are equal to the modification of the various equivalent forms of the utility model Fall into the application range defined in the appended claims.
