Abstract
The utility model discloses a support lateral adjusted pulley device, which comprises a support, a first pulley assembly and a second pulley assembly. The top of the support is fixedly connected with a door upper ledge, and the first pulley assembly and the second pulley assembly are rotatably connected on the outer lateral face of the bottom of the support through a pulley width adjusting device. By means of arrangement of the pulley width adjusting device, the first pulley assembly and the second pulley assembly can rotate on the outer lateral face of the bottom of the support simultaneously, so that horizontal component and vertical component on the outer lateral face of the bottom of the support of the axis distance between the first pulley assembly and the second pulley assembly can be adjusted in a large scale, and use requirements of users are met.
Description
Technical field
The utility model relates to sliding-door pulley device technique field, relates in particular to a kind of bracket side that is used for sliding door and transfers pulley gear.
Background technology
Traditional sliding-door pulley device mainly comprises the support that the top is fixedly connected with the door upper ledge; And directly being fixed on first pulley assembly and second pulley assembly on the frame bottom lateral surface, the sliding-door pulley device of this spline structure all can not be regulated the distance of shaft centers of first pulley assembly and second pulley assembly from horizontal component and vertical component on the frame bottom lateral surface.
And though this distance of shaft centers has appearred regulating on the market from the horizontal component on the frame bottom lateral surface and the sliding-door pulley device of vertical component, the scope of its adjusting is also less, can not satisfy people's demand.
The utility model content
In order to solve the problem that prior art exists; The purpose of the utility model is to provide a kind of distance of shaft centers that can regulate first pulley assembly and second pulley assembly on a large scale from horizontal component and vertical component on the frame bottom lateral surface, satisfies the bracket side of people's user demand and transfers pulley gear.
To achieve these goals, the technical scheme of the utility model employing is specific as follows:
A kind of bracket side is transferred pulley gear, comprises support, first pulley assembly and second pulley assembly; Propping up top of the trellis is fixedly connected with a upper ledge; Said first pulley assembly and second pulley assembly are rotationally connected with the frame bottom lateral surface through a pulley width adjusting device.
Particularly, said pulley width adjusting device comprises the screw frame, screw, regulating arm and brace; Screw frame top is connected in the frame bottom lateral surface through at least two rivets; Said first pulley assembly comprises first connecting axle and first pulley; Said second pulley assembly comprises second connecting axle and second pulley, and said first pulley and second pulley are fixed on the brace through first connecting axle and second connecting axle respectively; Said brace also is connected in screw frame upper outside face through another rivet; Screw frame bottom is provided with first screwed hole that is complementary with said screw; Regulating arm one end is socketed on first connecting axle, and the other end is provided with second screwed hole that is complementary with said screw; Said screw passes first screwed hole and second screwed hole successively.
The operating principle of the utility model is specially: the support of the utility model is fixedly connected the door upper ledge; When turn screw in first screwed hole and second screwed hole; Just can the rotational motion of screw be converted into the translational motion of regulating arm; Thereby drive the regulating arm motion; And because regulating arm socket first connecting axle also; First pulley assembly is fixedly connected through brace with second pulley assembly; When regulating arm moves, will drive first pulley assembly and second pulley assembly and rotate around the axle center that is fixed on brace in the rivet of screw frame upper outside face simultaneously, leave horizontal component and vertical component on the frame bottom lateral surface, satisfy people's user demand thereby reach the distance of shaft centers of regulating first pulley assembly and second pulley assembly on a large scale.
Compared with prior art, the utility model has produced following beneficial effect:
The utility model is through being provided with the pulley width adjusting device; First pulley assembly and second pulley assembly are rotated on the frame bottom lateral surface simultaneously; Leave horizontal component and vertical component on the frame bottom lateral surface thereby reach the distance of shaft centers of regulating first pulley assembly and second pulley assembly on a large scale, satisfied people's user demand.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A direction structure sketch map of Fig. 1.
The specific embodiment
As illustrated in fig. 1 and 2, the utility model mainly comprises support 1, the first pulley assembly 21 and second pulley assembly 22; Propping up top of the trellis 11 is fixedly connected with a upper ledge (figure does not show); Said first pulley assembly 21 and second pulley assembly 22 are rotationally connected with frame bottom lateral surface 12 through a pulley width adjusting device.
Particularly, said pulley width adjusting device comprises screw frame 3, screw 4, regulating arm 5 and brace 6; Screw frame top 31 is connected in frame bottom lateral surface 12 through at least two rivets 7; Said first pulley assembly 21 comprises first connecting axle 211 and first pulley 212; Said second pulley assembly comprises second connecting axle 221 and second pulley 222, and said first pulley 212 and second pulley 222 are fixed on the brace 6 through first connecting axle 211 and second connecting axle 221 respectively; Said brace 6 also is connected in screw frame upper outside face 311 through another rivet 7; Screw frame bottom 32 is provided with first screwed hole 321 that is complementary with said screw 4; Regulating arm 5 one ends are socketed on first connecting axle 211, and the other end is provided with second screwed hole 51 that is complementary with said screw 4; Said screw 4 passes first screwed hole 321 and second screwed hole 51 successively.
The operating principle of the utility model is specially: the support 1 of the utility model is fixedly connected door upper ledge (figure does not show); When turn screw 4 in first screwed hole 321 and second screwed hole 51; Just can the rotational motion of screw 4 be converted into the translational motion of regulating arm 5; Thereby drive regulating arm 5 motions; And because regulating arm 5 is gone back socket first connecting axle 211; First pulley assembly 21 is fixedly connected through brace 6 with second pulley assembly 22; When regulating arm 5 motions, will drive first pulley assembly 21 and second pulley assembly 22 and around that brace 6 is fixed on the axle center rotation of the rivet 7 of screw frame upper outside face 311 simultaneously, leave horizontal component and vertical component on frame bottom lateral surface 12, satisfy people's user demand thereby reach the distance of shaft centers of regulating first pulley assembly 21 and second pulley assembly 22 on a large scale.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
