Abstract
The utility model discloses an improved structure for the pulley assembly of a door-window floor rail. The pulley assembly of a door-window floor rail comprises a rectangular outer frame and an adjusting inner frame from outside to inside; a pulley member is arranged in the adjusting inner frame; the pulley member comprises two opposite clamping sheets; a left pulley and a right pulley are movably connected between the two clamping sheets; a pin penetrates through the middles of the front side and the rear side of the rectangular outer frame, the adjusting inner frame and the two clamping sheets; a plastic accessory is further arranged between the two pulleys, and the upper part of the plastic accessory is clamped between the two clamping sheets; a pin penetrates through the upper part of the plastic accessory to movable connect the plastic accessory with the two clamping sheets, the adjusting inner frame and the rectangular outer frame; the bottom of the plastic accessory stretches out of the bottom of the pulley member, and a U-shaped slide groove is formed in the plastic accessory; the U-shaped slide groove is deeper than U-shaped pulley grooves in the two pulleys; and the bottoms of the two pulleys are higher than the bottom of the plastic accessory. By adoption of the structure, the pulleys can be prevented from wear before installation, and doors and windows can be prevented from derailing, thus ensuring the pushing-pulling safety of the doors and windows.
Description
Technical field
The utility model relates to the door and window accessory, particularly the improvement structure of a kind of door and window ground rail pulley assembly.
Background technology
On the ground rail of sliding door, window, all need mounting door-window ground rail pulley assembly, can support door leaf or sash on it, lower can the slip along the ground rail with pulley, and everywhere rail inclination and swing up and down adjusting.When mounted, can be first that the door and window that assembles is on the ground, existing door and window trolley frame, pulley protrudes outside pulley assembly, when on the ground the door and window that assembles, because pulley directly supports on the ground, and can rub with ground, can cause pulley to be worn, in addition, because the U-shaped race bit depth of pulley assembly top sheave is more shallow, Quick push/pull door, window in use, pulley easily comes off from the ground rail, causes producing the danger of door and window derailing, have certain potential safety hazard, these all have much room for improvement.
The utility model content
The technical problems to be solved in the utility model is to provide the improvement structure of a kind of door and window ground rail pulley assembly, can not only prevent that limited slip wheel is worn before installation, and can prevent the door and window derailing, guarantees the safety of door and window push-and-pull.
for solving the problems of the technologies described above, the technical solution of the utility model is: the improvement structure that a kind of door and window ground rail pulley assembly is provided, door and window ground rail pulley assembly comprises from outside to inside the rectangle housing and regulates inside casing, regulate in inside casing and be provided with pulley component, it comprises two relative intermediate plates, be connected with two pulleys in left and right between two intermediate plates, pass the middle part of side before and after the rectangle housing with pin, regulate inside casing and two intermediate plates, also be provided with the plastics auxiliary between two pulleys, the top clamping of plastics auxiliary is between two intermediate plates, pin passes the top of plastics auxiliary, with plastics auxiliary and two intermediate plates, regulating inside casing and rectangle housing is flexibly connected, stretch out to below, pulley component bottom the bottom of plastics auxiliary, which is provided with the U-shaped chute, the degree of depth of U-shaped chute is greater than the degree of depth of U-shaped race on two pulleys, the bottom of two pulleys all exceeds on the bottom of plastics auxiliary.
The improvement structure of above-mentioned door and window ground rail pulley assembly, due to the setting of plastics auxiliary, the bottom of two pulleys all exceeds the bottom of plastics auxiliary, can be worn before installation by anti-limited slip wheel, and the degree of depth of U-shaped chute is larger, can not derail in the time of guaranteeing the door and window push-and-pull, very safe.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the stereogram of described utility model;
Fig. 2 is the split figure of described utility model.
Reference numeral:
1, rectangle housing, 2, regulate inside casing, 3, pulley component, 4, intermediate plate, 5, pulley, 6, pin, 7, the plastics auxiliary, 8, the U-shaped chute, 9, the U-shaped race.
The specific embodiment
Referring to Fig. 1-Fig. 2, the improvement structure of a kind of door and window ground rail pulley assembly is provided, door and window ground rail pulley assembly comprises from outside to inside rectangle housing 1 and regulates inside casing 2, regulate in inside casing 2 and be provided with pulley component 3, it comprises two relative intermediate plates 4, be connected with two pulleys 5 in left and right between two intermediate plates 4, pass middle part, adjusting inside casing 2 and two intermediate plates 4 of rectangle housing 1 front and back side with pin 6.Also be provided with plastics auxiliary 7 between two pulleys 5, the top clamping of plastics auxiliary 7 is between two intermediate plates 4, and pin 6 passes the top of plastics auxiliary 7, and plastics auxiliary 7 and two intermediate plates 4, adjusting inside casing 2 and rectangle housings 1 are flexibly connected.Stretch out to pulley component 3 bottoms belows the bottom of plastics auxiliary 7, which is provided with U-shaped chute 8, the degree of depth of U-shaped chute 8 is greater than the degree of depth of U-shaped race 9 on two pulleys 5, during the door and window push-and-pull, U-shaped chute 8 slides on the ground rail with U-shaped race 9 simultaneously, can not derail in the time of guaranteeing the door and window push-and-pull, safer.The bottom of two pulleys 5 all exceeds on the bottom of plastics auxiliary 7, and erection of doors and windows is before on the ground rail, and the door and window bottom is supported on the ground with plastics auxiliary 7, rather than directly supports on the ground with pulley 5, thereby can prevent that limited slip wheel 5 is worn before installation.
Above-described embodiment is preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of doing change, and all should belong to protection category of the present utility model.
