Introduce respectively two embodiment below in conjunction with accompanying drawing.
(1) embodiment mono-
As shown in Fig. 1-Figure 11, the sliding door of first embodiment comprises casing 10, interior chuck 20 and two pulleys 30,40 with epirelief lower sheave.
Wherein, casing 10 is with interior chuck 20 the similar cuboid adapting to door leaf bottom end face.Interior chuck 20 comprises front panel 21, squab panel 22, left side wall panel 23.Casing 10 is slightly larger than interior chuck 20, comprises front panel 11, squab panel 12, left side wall panel 13, right side wall panel 14, top flap 15; 15 of top flap are arranged on central authorities and the left and right side end position at top, and other place, top is not blocked, and the top flap 15 of left and right side is provided with the screw 17,18 for whole assembly being installed on to door leaf bottom.
Interior chuck 20 adapts to casing 10, and interior chuck 20 up inserts in casing 10 from bottom, is located in casing 10.In the present embodiment, casing 10 is provided with the inclined hole 16 that runs through its forward and backward wallboard 11,12, and interior chuck 20 is provided with the rivet hole 26 that runs through its forward and backward wallboard 21,22, and rivet hole 26 is corresponding with inclined hole 16 positions and adapt to inclined hole 16 size.Rivet 60, through inclined hole 16 and rivet hole 26, is connected in interior chuck 20 in casing 10.Like this, interior chuck 20 just can have rotation to a certain degree around rivet 60 in casing 10, and its rotation amplitude is subject to the restriction of the top flap 15 of left and right side.
Adapt with said structure, the left side wall panel 13 of casing 10 is provided with screwed hole 131, and the relevant position of the sidewall paneling 23 of interior chuck 20 is provided with adjustment hole 231, and adjustment hole 231 has certain length in vertical direction.The inner side of the sidewall paneling that adjustment hole 231 is set of interior chuck 20 is provided with regulating block 232, and regulating block 232 is provided with screw 2320.On the forward and backward wallboard of the inner side of regulating block 232, interior chuck 20, be provided with the limit rib 2321 (only show outside in Fig. 7, in fact also there is outstanding limit rib forward and backward wallboard inner side) of restriction regulating block.Screw rod 50 is through the screwed hole 131 of casing 10, the adjustment hole 231 of interior chuck 20, the screw 2320 of regulating block 232, to realize the adjusting of internal chuck.Further, in the outside of the left wallboard 13 of casing 10, on screw rod 50, be plugged with spacing fixture block 51, the state of standing screw 50.
Be screwed into or the screw rod 50 of back-outing, just can change the pressure on top surface of internal chuck 20, interior chuck 20 is rotated counterclockwise or clockwise a little around rivet 60, thus the height of adjustable pulley.Like this, in the time there is mismachining tolerance or alignment error, just can carry out by adjusting screw(rod) 50 height of adjustable pulley, and the state of final fixed block.The above-mentioned adjustment hole 231 that has a certain length in vertical direction is just given and space, to adapt to the upstream or downstream of the screw rod 50 rotating along with interior chuck 20.After regulating, the spacing fixture block 51 of pegging graft on screw rod 50, just can stop screw rod 50 to continue mobile, fixes its state.
Wherein, the forward and backward wallboard 21,22 of interior chuck 20 comprises respectively corresponding to top lug boss 210,211,220,221 protruding upward separately, the axis hole 31,41 of pulley 30,40 is arranged at respectively lug boss 210,220 and lug boss 211,221, in other embodiment of the utility model, axis hole also can be arranged on the position with lug boss vertical non-alignment, if the position in figure is to moving down.Above-mentioned rivet hole 26 is between lug boss 210,220 and lug boss 211,221.
The axle 27 of pulley 30,40 fits in respectively in axis hole 31,41, and between the forward and backward wallboard 21,22 of pulley 30,40 in interior chuck 20, and its top stretches out from the top of interior chuck 20, and stretch out from the bottom of interior chuck 20 its bottom.Like this, axis hole can be brought up to lug boss (higher than casing 10 and interior chuck 20), or at least brings up to interior chuck 20 tops and intensity is still enough; The raising of axis hole makes the size of pulley not be subject to the restriction of interior chuck height, can arrange greatlyr than pulley of the prior art, more stable when therefore door leaf moves, and linear velocity increase, and speed is faster, and pulley abrasion resistance is higher.
In addition, for the ease of interior chuck 20 is inserted in casing 10, a side of interior chuck 20 is preferably opening, side plate is not set, interior chuck preferably adopts Elastic Steel, in order to strengthen its transverse strength, on interior chuck 20, be provided with the support axis hole a, b, c, the d that run through its forward and backward wallboard 21,22, the back shaft of equal fixed lateral in these support axis holes.
When installation, the screw 17,18 of the top flap 15 by casing 10, tighten the screws from the bottom up, just can be fixed on door leaf C bottom by epirelief lower sheave A, B for whole sliding door.Because pulley increases, stretch out from casing 10 tops, therefore, be provided with the groove for holding pulley 30,40 in the bottom of door leaf C.The top of casing 10 equals the height of door leaf attachment rail to the vertical distance of the bottom of pulley 30,40, make door leaf that rear bottom is installed and press close to doorframe (as shown in figure 11).
(2) embodiment bis-
As shown in Figure 12-Figure 17, the sliding door of second embodiment with epirelief lower sheave comprise casing 10 ', interior chuck 20 ' and pulley 30 '.
Compared with above-described embodiment one, the difference of the present embodiment is: in the present embodiment, pulley only has one.Correspondingly, lug boss only has one, be labeled as 23 '.For the stability of interior chuck 20 ' connection, rivet hole and inclined hole are two; Rivet hole external jacket 10 ' on, be labeled as 11 ', 12 ', correspondingly inclined hole is arranged on interior chuck 20 ' upper, be labeled as 21 ', 22 ', and two inclined holes are parallel to each other.Lug boss 23 ' position in two inclined holes 21 ', 22 ' between.Two rivets respectively through inclined hole 21 ' and rivet hole 11 ', inclined hole 22 ' and rivet hole 12 '.Certainly, in other embodiment of the utility model, also can inclined hole be arranged on casing as first embodiment, rivet hole is arranged on to interior chuck, this is equivalents.
This sliding door is arranged on epirelief lower sheave behind the bottom of door leaf, turn screw rod 50 ', just can order about interior chuck 20 ' along with rivet along inclined hole 11 ', 12 ' movement and rise or decline, thereby adjustable pulley 30 ' height, with reply alignment error and accuracy of manufacture problem, ensure the smooth and easy operation of pulley 30 ' in orbit.
Above-mentioned two embodiment, thus rivet moves and drives inner clip cover rise or move down along inclined hole, thus can realize adjusting, to adapt to exist the situation of foozle or alignment error, guarantee door leaf is installed not tilt and move smooth and easy; Especially the structure of embodiment mono-more makes rivet become fulcrum, makes two pulleys Automatic Levelling in the time being under pressure.Moreover, the axis hole that the setting of the lug boss of interior chuck can be installed pulley rises, thereby the vertical distance of axis hole and track is strengthened, namely strengthen the radius of pulley, make the size of pulley no longer be limited to the height of casing, and lug boss can also increase the intensity at axis hole place, strengthen the compression capability of pulley, increase speed and the smoothness of door leaf operation simultaneously; Solve and in prior art, suffered from pulley and cannot do large all limitations, can replace existing all lower sheaves completely.
Described above is only preferred embodiment of the present utility model, certainly can not limit protection domain of the present utility model with this; Any equivalents for technical solutions of the utility model and replacement, all within protection domain of the present utility model.
