Abstract

The utility model relates to a push-pull type door, which overcomes the disadvantages of the prior push-pull type door including inflexible pushing and pulling, frequent occurrence of displacement deformation between a track and a roller wheel and poor sealing effect of the push-pull type door. The push-pull type door consists of a frame and a door leaf, wherein the frame comprises an upper frame, a lower frame and a side frame; the door leaf comprises an upper, a lower, a middle jamb and a side jamb; a groove of the lower is provided with a pulley, and a slickenside of the pulley is sunken inwards; the lower frame is provided with a horizontal track with a hemispheric top; and the outside of a horizontal neck of the upper frame is provided with a horizontal wool top, while the inside is provided with a horizontal rubber strip. The push-pull type door is not easy to generate inside and outside displacement, and does not sway when closed and opened, thereby ensuring flexible motion; moreover, the push-pull type door not only prolongs service life, but also improves sealing property.

Description

A kind of sliding door

Technical field

The utility model relates to a kind of building product, particularly relates to a kind of sliding door.

Background technology

There are following shortcomings in present most of sliding door product:

(1) present most of sliding door adopts T shape or rectangular rail, cooperates defective tightness with pulley, and outer displacement in easily producing makes the pulley operation dumb or tightened, and increases and weares and teares, and has reduced the application life of sliding door.And because the slit that displacement produces makes sealing performance bad.

(2) for strengthening sealing effectiveness, what all used inside and outside both sides between door leaf and the frame is sealing joint strip or wool top.If all adopt sealing joint strip, active fan unlatching frictional force is big; If but all adopted wool top, then sealing effectiveness would be undesirable.

(3) existing sliding door lower frame is horizontal, is unfavorable for waterproof and draining.

(4) track and lower frame generally adopt monolithic construction, have limited the intensity of track and have been difficult for replacing and maintenance.

(6) be generally metal between hooked rabbet and directly connect, sealing effectiveness is relatively poor.

Summary of the invention

Dumb in order to overcome existing sliding door push-and-pull, easily produce displacement between track and roller, and sliding door sealing effectiveness defect of bad, the utility model designs a kind of new-type sliding door.

The purpose of this utility model is achieved in that sliding door is made up of the door leaf that can open mutually, close and frame, and the framework clamping that door leaf is made up of top, below, smooth rabbet and hooked rabbet is integral, and frame comprises upper ledge, lower frame, frame.The lower bottom part of door leaf is the downward groove of the recess of a level, and pulley is housed in the groove.Be equipped with fixing upper ledge on the top of door leaf, the bottom of door leaf is equipped with a fixing lower frame, and following frame bottom is equipped with a horizontal rail.The sliding surface of pulley is a concave shaped in the described lower grooves, and the top that lower frame gets on the right track is a hemispherical, and the sliding surface profile of track and described pulley is complementary.

Upper ledge is the downward horizontal draw-in groove of a recess with the place of matching, top of door leaf, and the draw-in groove outer lower portion is equipped with the wool top of one level, and the inboard of draw-in groove is equipped with the adhesive tape of one level.

Sliding rail of the present utility model adopts hemispherical, cooperates closely accurate positioning with pulley, outer displacement in being difficult for producing can not rock door leaf when closing and open, motion flexibly, not only increase the application life of door leaf, also improved the sealing performance of door leaf simultaneously.Different sealing joint strip and wool top are used in inside and outside both sides between active fan and the doorframe, have not only further strengthened the sealing performance of sliding door, and it is less to close when opening suffered resistance than existing door leaf.

Description of drawings

Fig. 1 is a side-looking longitudinal sectional view of the present utility model.

Fig. 2 is a vertical view cutaway drawing of the present utility model.

1 door leaf among the figure, 2 tops, 3 belows, 4 upper ledges, 5 lower frames, 6 wool tops, 7 adhesive tape, 8 pulleys, 9 tracks, 10 adhesive tape, 11 raised type smooth rabbets, 12 indent formula smooth rabbets, 13 vertical wool tops, 14 vertical adhesive tape, 15 hooked rabbets, 16 frames, 17 sponges.

The specific embodiment

See figures.1.and.2, the utility model is to constitute like this: sliding door is made up of door leaf 1 and the frame that can open mutually, close.The framework clamping that door leaf 1 is made up of top 2, below 3, raised type smooth rabbet 11, indent formula smooth rabbet 12 and hooked rabbet 15 is integral.Frame comprises upper ledge 4, lower frame 5, frame 16, and wherein, 3 bottoms, below of door leaf 1 are the downward groove of recess of a level, and pulley 8 is housed in the groove, and the sliding surface of pulley 8 is a concave shaped.The bottom of door leaf 1 is equipped with a fixing lower frame 5, and the top that lower frame 5 bottoms are equipped with a level is hemispheric track 9.The inner concave of the pulley 8 on the below 3 and the hemisphere end face of track 9 mate mutually, and contact surface fits tightly together, and accurate positioning cooperates tightly, and door leaf can be slided on track 9 smoothly, and door leaf 1 can be out of shape by double swerve.Adopting separate type between track 9 and the lower frame 5, can be embedded connection, also can use bolt, pulling rivet to connect or other mechanical systems connections.What track 9 used is that the material that is higher than lower frame 5 intensity is made, and compares with the existing sliding door of identical material manufacturing, and the intensity of track not only can improve greatly, and is easy to change and maintenance.Be equipped with fixing upper ledge 4 on the top of door leaf 1, upper ledge 4 is the downward horizontal draw-in groove of a recess with 2 places of matching, top of door leaf 1.The top 2 of door leaf 1 can horizontally slip in draw-in groove.Be equipped with the wool top 6 of one level in the draw-in groove outer lower portion of upper ledge 4, the inboard of draw-in groove is equipped with the adhesive tape 7 of one level.Wool top 6 and adhesive tape 7 are clipped in top 2 wherein, play tight retaining ash, insulation, sealing function.Also be equipped with the adhesive tape 10 of one level in lower frame 5 inside upper part, between the below 3 of door leaf and the lower frame 5 by adhesive tape 10 sealings.Zhuan Zhi waterproof and draining for the benefit of, lower frame 5 bottoms are outward-dipping ramped shaped, when sleet sky or top current following times are arranged like this, water will flow to the outside along the slope, can not enter indoor.As further insulation, seal approach, the corresponding smooth rabbet of two fan door leafs 1, one is raised type smooth rabbet 11, another is an indent formula smooth rabbet 12.Two fan door leafs 1 are when cutting out, and the evagination of raised type smooth rabbet 11 snaps in the groove of indent formula smooth rabbet 12 coupling mutually.In indent formula smooth rabbet 12 grooves, the outside is equipped with together vertically wool top 13.With the inboard of vertical wool top 13 corresponding grooves, be equipped with together vertically adhesive tape 14.When sliding door is closed,, also play insulation, seal and slow down the effect of collision because vertical wool top 13 and vertical adhesive tape 14 are with the evagination clamping therein.In addition,, be separately installed with vertical sponge 17 one, further play the effect that makes sealing between hooked rabbet 15 and the frame, insulation, retaining ash at two frame inner edges and hooked rabbet 15 opposite positions.
