The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described in detail.
As depicted in figs. 1 and 2, the utility model provides a kind of pulley gear, and it comprises pulley yoke 1, lifting shaft 3 and assembly pulley, and described assembly pulley comprises two head pulleys 2 and a lifting pulley 4, described two head pulleys 2 are installed on the pulley yoke 1 by screw 20, and are positioned at the same level height; Described lifting pulley 4 is installed on the lifting shaft 3, and lifting shaft 3 vertically is installed on the pulley yoke 1 elastic telescopic.
As elastic telescopic install preferred embodiment a kind of, described pulley yoke 1 is provided with a cylindrical containing hole 13, the bottoms in the containing hole 13 are provided with a spring 31, described lifting shaft 3 is installed on spring 31 tops in the containing hole 13.
As shown in Figure 4, described pulley gear also comprises a fixture 30, and described lifting shaft 3 is provided with a blind hole 32, and described fixture 30 passes pulley yoke 1 and screws in the blind hole 32 of lifting shaft 3.
Preferably, described fixture 30 is a holding screw, and blind hole 32 inwalls of described lifting shaft 3 are provided with the screw thread with the holding screw coupling.
For make things convenient for assembly pulley towards adjustment, described pulley gear also comprises sliding support 51 and support 52, described pulley yoke 1 a dorsad side of assembly pulley is provided with the connecting portion 15 of a projection, described sliding support 51 articulates by a rotating shaft 50 and described connecting portion 15; Be provided with the chute of vertical direction in the described support 52, described sliding support 51 is installed in the chute of described support 52.
For making things convenient for the height of adjustable pulley group, preferably, described rotating shaft 50 is screw rod, which is provided with screw thread, and the pivoted hole inwall of described sliding support 51 is provided with the screw thread that is complementary with screw rod.
For making things convenient for being connected of pulley gear and shower room movable door, described pulley gear also comprises fixture block group 6, described fixture block group 6 comprises clamp nut 62, is located in the fixedly rubber cushion 60 of dodge gate both sides, trip bolt 61 and trim 63, described clamp nut 62 is located at a dorsad side of pulley yoke 1 of support 52, described trip bolt 61 is from after fixedly a side of rubber cushion 60 is passed, be threaded with described clamp nut 62 at the fixing opposite side of rubber cushion 60, described trim 63 covers in fixedly that the trip bolt 61 of rubber cushion 60 penetrates side.
Be the position of restriction head pulley 2, described pulley yoke 1 also is being provided with protruding spacing card 21 to head pulley with head pulley 2 junctions.
Three pulley gears of prior art must slip into the end of pulley gear from guide rail first during installation, hang dodge gate is installed, and are very inconvenient.As shown in Figure 3 and Figure 4, pulley gear of the present utility model, when mounted, first shower room movable door is fixed in the fixture block group 6 of pulley gear, then lift dodge gate, the lifting pulley 4 of top the pulley yoke 1 is headed into the upper edge of guide rail 9 inboards from guide rail 9 outsides, and continue upwards firmly, make lifting shaft 3 to lower compression, until head pulley 2 can be put into the pulley track of guide rail 9 side-lowers.After head pulley 2 was placed and finished, lifting pulley 4 also appliance for releasing single was got back to the extreme higher position.The head pulley 2 that is positioned at the pulley gear below mainly plays load-bearing and slip effect, and the lifting pulley 4 that is positioned at the top is mainly used in blocking edge on the guide rail 9, prevents that pulley gear from coming off when sliding.
