Abstract
The utility model provides a rotating arm connecting structure. The rotating arm connecting structure comprises a body, a fixed seat, a fixed shaft, bearings, a thrust bearing, steel tubes and a connecting member, wherein the fixed seat is fixedly mounted at one side of the body, the fixed shaft is arranged at the outer side of the fixed seat, the fixed shaft is sleeved with the bearings, the bottom of the fixed shaft is sleeved with the thrust bearing, the peripheries of the bearings are tightly sleeved with the steel tubes, and the connecting member is fixedly welded to the steel tubes; a rotating arm is fixedly connected with the steel tubes, on which the connecting member is mounted, through a steel plate, on which a connecting member is fixedly mounted. The rotating arm connecting structure has the following advantages that the structure is simple, and the use is convenient; through additionally arranging the plain bearings and the thrust bearing between the steel tubes, the rotating arm is safe and reliable in rotation, high in sensitivity and long in service life and is applicable to rotating structures of all kinds of machinery and equipment.
Description
Technical field
the utility model relates to machinery field, particularly relates to the linkage structure between the rotating machinery of machinery.
Background technique
machinery refers to the general name of machine and mechanism.Machinery can help people to reduce work difficulty or labour-saving tool device exactly, as the article of chopsticks, broom and tweezers one class, can be called as machinery, and they are simple and mechanical.And complicated machinery is exactly to consist of the simple and mechanical of two or more.Conventionally the machinery of these more complicated is called to machine.From the viewpoint of structure and motion, mechanism and machine indistinction, be loosely referred to as machinery.A set of machinery comprises a lot of structural type, as track, lifting structure, mobile mechanism, rotational structure, power source etc.The rotating machinery of existing machinery equipment normally connects by two sleeves that can mutually rotate, and which sensitivity is low, and working life is short, affects manufacturing efficiency.Therefore Placement, how to improve machinery rotating machinery becomes the major issue that mechanical field need to solve.
Model utility content
low for solving the rotational structure sensitivity of machinery in prior art, and working life short problem, the utility model provides following technological scheme:
a kind of rotating arm connecting structure, it comprises body, be fixedly installed in the fixed base of described body one side, be arranged at described fixed base outside stationary axle, be sheathed on described stationary axle bearing, be sheathed on described stationary axle bottom thrust-bearing, be locked on the steel pipe of described bearing periphery and the link that is fixedly welded in described steel pipe, pivoted arm is fixedly connected with the steel pipe that link is installed by being installed with the steel plate of link.
as a kind of preferred version of the present utility model, plural described bearing is installed on described stationary axle.
as another kind of preferred version of the present utility model, described link is the arcuate structure that is provided with attachment hole.
as another preferred version of the present utility model, between described two or more link, by bolt, connect.
as another preferred version of the present utility model, described steel plate has two, and the link that is connected in described steel plate is fixedly clamped and is installed on the link of described steel pipe.
as another preferred version of the present utility model, described stationary axle is solid manganese steel.
the utility model has the following advantages: the utility model is simple in structure, easy to use, by increasing plain bearing and thrust-bearing between the steel pipe in mutually rotation, make the rotation of pivoted arm safe, reliable, highly sensitive, long service life, be applicable to the rotational structure of various machinery.
Accompanying drawing explanation
fig. 1 the utility model structural representation.
number in the figure is:
1-body, 2-fixed base, 21-stationary axle
22-bearing, 23-thrust-bearing, 3-steel pipe
4-link, 5-steel plate, 6-pivoted arm.
Embodiment
below this process example is elaborated, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
as shown in Fig. 1 the utility model structural representation, a kind of rotating arm connecting structure, it comprises body 1, be fixedly installed in the fixed base 2 of described body 1 one sides, be arranged at described fixed base 2 outsides stationary axle 21, be sheathed on described stationary axle 21 bearing 22, be sheathed on described stationary axle 21 bottoms thrust-bearing 23, be locked on the steel pipe 3 of described bearing 22 peripheries and the link 4 that is fixedly welded in described steel pipe 3, pivoted arm 6 is fixedly connected with the steel pipe 3 that link 4 is installed by being installed with the steel plate 5 of link 4.
plural described bearing 22 is installed on described stationary axle 21.Described link 4 is for being provided with the arcuate structure of attachment hole.Between described two or more link 4, by bolt, connect.
described steel plate 5 has two, and the link 4 that is connected in described steel plate 5 is fixedly clamped and is installed on the link 4 of described steel pipe 3.Described stationary axle 21 is solid manganese steel.
The above; it is only one of embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
