Description
Technical field
The utility model is specifically related to a kind of ball pulley of sliding door of building finishing.
Background technology
The ball pulley of existing sliding door utilizes pedestal to be combined with sliding door door-plate, then by assisting the relative sliding of ball set and ball, making ball be able to roll on slide rail, and then making ball pulley that sliding door door-plate can be driven to move.Wherein, pedestal can be subject to the weight of sliding door door-plate and produce a downward strength, simultaneously, ball can be subject to the support of slide rail, ball is made to maintain same position, but, auxiliary ball set is when being subject to pedestal and ball extrudes, ball struts auxiliary ball set, each auxiliary ball of auxiliary ball set is moved laterally, cause the sidewall of each auxiliary ball extruding pedestal, and ball falls into into from the central authorities of auxiliary ball set, cause, with auxiliary ball set, stuck situation occurs, ball cannot be rolled in orbit, and then cause the slip of sliding door door-plate to have some setbacks, and ball and track can be made to produce very large friction noise.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of ball pulley of sliding door of building finishing, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of ball pulley of sliding door of building finishing, comprise: a upper cover, one pedestal and a fixed axis, multiple ball hole and a fixing hole is covered with on described, described pedestal is provided with multiple circular groove, the bottom surface of each described circular groove is outward-dipping, a ball and an auxiliary ball set is provided with in each described circular groove, the diameter of described circular groove is greater than the diameter of described ball hole, described auxiliary ball set is provided with multiple auxiliary ball, the rounded arrangement in bottom surface that described auxiliary ball is located at described circular groove, and described auxiliary ball is located at the below of described ball, described fixed axis is through described fixing hole and described pedestal, described upper cover is located on described pedestal, and the corresponding described circular groove of described ball hole is arranged.
Be covered with multiple column on described, described pedestal is provided with multiple engagement groove, and described column is arranged with described engagement groove is mutually corresponding.
Described upper cover is rounded, and described pedestal is also rounded, and described upper cover is mutually corresponding with the profile of described pedestal, and the described ball in described pedestal is radially arranged.
The beneficial effect of technique scheme of the present utility model is as follows:
The ball pulley of the sliding door of building finishing of the present utility model due to the bottom surface of circular groove outward-dipping, the center of gravity of each ball is made to maintain the outside of circular groove, when ball pulley is under stress, each ball can not be absorbed in by the centre of auxiliary ball set, be conducive to avoiding occurring auxiliary ball set and the stuck situation of ball, be conducive to the generation avoiding noise simultaneously; Due on be covered with multiple column, and pedestal correspondence is provided with multiple engagement groove, when upper cover and pedestal in conjunction with time, only need the position of corresponding column and engagement groove, can be in conjunction with, do not need the comparison carrying out position in addition, be conducive to shortening built-up time.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figures 1 to 4, the utility model embodiment provides a kind of ball pulley of sliding door of building finishing, one upper cover 10, one pedestal 20 and a fixed axis 30, upper cover 10 is provided with multiple ball hole 11 and a fixing hole 12, pedestal 20 is provided with multiple circular groove 21, the bottom surface 211 of each circular groove 21 is outward-dipping, ball 22 and an auxiliary ball set 23 is provided with in each circular groove 21, the diameter of ball 22 is greater than the diameter of ball hole 11, ball 22 has part to protrude outside upper cover 10, auxiliary ball set 23 is provided with multiple auxiliary ball 231, and auxiliary ball 231 is located at the bottom surface 211 of circular groove 21, auxiliary ball 231 is located at the rounded arrangement in below of ball 22.
Fixed axis 30 is through fixing hole 12 and pedestal 20, and can be used for combined sliding door door-plate, upper cover 10 is located on pedestal 20, and ball hole 11 corresponding circle connected in star 21 is arranged, and makes ball 22 expose part outside through the ball hole 11 of each correspondence, and can contact track L.
As shown in Figure 3, the bottom surface 211 of circular groove 21 is in outward-dipping shape, make the center of gravity of ball 22 not at the center of auxiliary ball set 23, and remain on outer fix, form the arrangement of radiation-like, ball 22 can not be directly absorbed between each auxiliary ball 231, can avoid ball 22 and auxiliary ball set 23 that stuck situation occurs, sliding door is slided smooth and easy, the generation of noise can be avoided simultaneously.
Upper cover 10 is provided with multiple column 13, and pedestal 20 is provided with multiple engagement groove 24, and make column 13 mutually corresponding with engagement groove 24, upper cover 10 can be made directly to combine according to the relative position of column 13 with engagement groove 24, circular groove 21 can be made directly to correspond to the position of ball hole 11 simultaneously, save many built-up times.Upper cover 10 is rounded with pedestal 20 and mutually correspondingly arrange, and is conducive to the slip of sliding door in track L.
It is more than preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
