Description

Technical Field

[0001] The invention relates to the field of mechanical transmission components, in particular to a roller that rolls in a curtain track, and a curtain track with the roller. Background Art

[0002] Tracks are used to hang curtains. Pulleys are an important part of the track, which can make the opening and closing of curtains more flexible and convenient. Due to the limitations of existing technology, the existing curtain pulleys have a single functional structure. The pulleys can only be used normally on tracks with the pulley groove opening perpendicular to the ground. As a result, the existing curtain pulleys have the following defects and deficiencies:

[0003] First, the pulley can only be used on a track with the pulley groove perpendicular to the ground. If the track is installed at an angle, the pulley will not pull smoothly or even get stuck. For special window structures such as inclined wall windows on the top floor of a villa or a high-rise building, they cannot be installed and used normally. The only option is to destroy the original wall structure and level the inclined surface before installation, which increases costs and labor consumption, takes up space, damages the original structure, and affects the overall appearance.

[0004] Second, the pulley can only be used on a track with the pulley groove pointing downward and perpendicular to the ground. After the pulley is mounted with the curtain, the track and the curtain must maintain a distance and cannot touch each other, otherwise it will affect the normal sliding of the pulley, causing light leakage between the existing track and the curtain.

[0005] Third, the pulley can only be used on a track with the pulley groove opening perpendicular to the ground. The existing pulleys are only modified in shape and size based on this basic point. These pulleys of different shapes and sizes bring inconvenience to users in later replacement and maintenance. Summary of the Invention

One polyurethane rubber-coated bearing wheel, one axle and two limiting wheel axle sleeves form a group of transmission components. The four groups of transmission components enter the fixed seat respectively through the bent shaft splints of the fixed seat. The bent shaft splints of the fixed seat are flattened by tools to connect the axle connected with the polyurethane rubber-coated bearing wheel and the limiting wheel axle sleeve to the shaft groove of the fixed seat.

[0009] Preferably, the bearing of the polyurethane rubber-coated bearing wheel is made of stainless steel, the rubber layer of the polyurethane rubber-coated bearing wheel is made of wear-resistant and silent polyurethane material, and the polyurethane rubber-coated bearing wheel has excellent transmission performance.

[0010] Preferably, the two extensions integrally connected to the boom and the two fixed seats integrally connected to the two extensions constitute the roller body. The roller body is made of aluminum alloy material, which has good bending and shaping properties and meets the bending and flattening requirements of the fixed seat shaft splint. The boom has specifications and models of different lengths.

[0011] Preferably, a lifting eye hole is provided at the front end of the lifting arm, the lifting eye hole is movably connected to the lifting ring, and the center of gravity of the lifting ring is always facing the ground.

[0012] Preferably, the wheel axle is connected with a polyurethane rubber-coated bearing wheel and a limiting wheel axle sleeve, the limiting wheel axle sleeve is made of stainless steel, the inner diameter of the polyurethane rubber-coated bearing wheel axle hole is the same as the inner diameter of the limiting wheel axle sleeve, and the bearing wheel core protruding on both sides of the polyurethane rubber-coated bearing wheel and the corresponding two inner sides of the fixed seat axle clamping plates are each connected with a limiting wheel axle sleeve, the distance between the bearing wheel core protruding on one side of the polyurethane rubber-coated bearing wheel and an inner side surface of the corresponding fixed seat axle clamping plate is equal to the length of one limiting wheel axle sleeve, and the shaft connected to the protruding polyurethane rubber-coated bearing wheel The two limiting wheel axle sleeves on both sides of the bearing wheel core clamp the polyurethane rubber-coated bearing wheel, and the polyurethane rubber-coated bearing wheel will not shake, so that the outer polyurethane rubber layer of the polyurethane rubber-coated bearing wheel will not contact the roller body. The outer diameter of the limiting wheel axle sleeve is smaller than the inner diameter of the outer polyurethane rubber of the polyurethane rubber-coated bearing wheel. The limiting wheel axle sleeve will not contact other parts of the polyurethane rubber-coated bearing wheel except the protruding bearing wheel cores on both sides. The mechanical transmission performance of the polyurethane rubber-coated bearing wheel is not affected, and the roller as a whole can maintain a straight line operation.

[0013] A curtain track using the above-mentioned roller comprises a track, wherein a roller groove is provided in the track and is connected to openings at both ends of the track, the roller groove is a polygonal side channel structure extending along the length of the track, and one side channel of the roller groove polygonal side channel structure is provided with a notch extending along the length of the track, and four side channels of the roller groove polygonal side channel structure are used for the four polyurethane rubber-coated bearing wheels of the roller to fit and press together and roll.

[0014] Furthermore, the four polyurethane rubber-coated bearing wheels of the roller are pressed against four of the side tracks of the polygonal side track structure of the roller groove and move in a rolling manner. The roller boom is suspended outside the notch of the roller groove. The roller boom will not come into contact with the track. The multiple rollers are arranged at intervals along the roller groove.

[0034] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0035] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0036] It should be noted that if Figures 3 to 5 As shown, the roller body 11 composed of the bent fixed seat shaft clamping plates 112a1 and 112b1 is a semi-finished product structure diagram produced to facilitate the transmission component to enter the fixed seat shaft groove 1112. The subsequent insertion of the transmission component, the use of tools to flatten the bent fixed seat shaft clamping plates 112a1 and 112b1, and the insertion of the lifting ring 12 are all completed by the manufacturer, as shown in FIG. Figures 1 to 2 The figure shows the finished product structure diagram delivered to the user.

[0037] like Figures 1 to 7 As shown, the present invention provides a multifunctional curtain roller assembly 1, comprising a roller body 11, a hanging arm 111, a hanging ring 12, a limiting wheel shaft sleeve 13, a wheel shaft 14, a polyurethane rubber-coated bearing wheel 15, and a curtain track 2 using the above-mentioned roller assembly 1.

[0038] A hanging eye hole 1111 is provided at the front end of the hanging arm 111 , and a hanging eye 12 is flexibly connected to the hanging eye hole 1111 . The hanging eye 12 is used for hanging a curtain hook.

[0039] The side walls on both sides of the rear end of the suspension arm 111 are integrally connected with cross-shaped extensions 113a and 113b, and the outer side walls of the two extensions 113a and 113b are integrally connected with cross-shaped fixing seats 112a and 112b, respectively, to form the roller body 11.

[0040] The fixing seats 112 a and 112 b are provided with shaft grooves 1112 .

[0041] The fixed seat shaft groove 1112 is connected to the wheel axle 14, and the wheel axle 14 is connected to the polyurethane rubber-coated bearing wheel 15 and the limiting wheel axle sleeve 13. The bearing wheel core 1511 protruding on both sides of the polyurethane rubber-coated bearing wheel 15 and the inner sides of the corresponding two fixed seat shaft clamps 112a1 and 112b1 are each connected with a limiting wheel axle sleeve 13. A polyurethane rubber-coated bearing wheel 15, a wheel axle 14 and two limiting wheel axle sleeves 13 form a set of transmission components. The four sets of transmission components enter the fixed seats 112a and 112b through the bent shaft clamps 112a1 and 112b1 of the fixed seat respectively. The bent shaft clamps 112a1 and 112b1 of the fixed seat are flattened by tools to 112a2 and 112b2 to connect the wheel axle 14 connected with the polyurethane rubber-coated bearing wheel 15 and the limiting wheel axle sleeve 13 to the shaft groove 1112 of the fixed seat.

[0042] The roller groove 21 is a polygonal side structure extending along the length of the track 2. One side of the polygonal side structure of the roller groove 21 is provided with a slot 211 extending along the length of the track 2. Four side lanes 212 of the polygonal side structure of the roller groove 21 are used for the four polyurethane-coated bearing wheels 15 of the roller 1 to fit and press against each other for rolling.

[0043] The four polyurethane rubber-coated bearing wheels 15 of the cross-shaped fixing seats 112a and 112b enter the roller groove 21 corresponding to the four side paths 212 of the roller groove 21 of the track 2, and the curtain is hung on the ring 12 at the top of the hanging arm 111 extending out of the roller groove notch 211.

[0044] like Figures 8 to 10 As shown, the arm 111 has different lengths and models, and the corresponding model can be selected according to the situation. When the arm 111 is facing sideways or tilted upward, the arm 111 is longer. After the curtain is hung on the ring 12, the curtain will not come into contact with the track 2 and the curtain covers the lower half A of the track 2, which has a shading function. When the arm 111 is facing downward, the arm 111 is shorter to avoid excessive light leakage due to a large gap between the track 2 and the curtain.

[0045] Implementation principle: The four polyurethane rubber-coated bearing wheels 15 of the curtain roller 1 of the present invention are pressed against the four side roads 212 of the roller groove 21. The track 2 flips the roller groove notch 211 to any angle. The four polyurethane rubber-coated bearing wheels 15 of the roller 1 are not affected by the flipping angle and can always press against the four side roads 212 of the roller groove 21 and roll left and right normally. A limiting wheel axle sleeve 13 is connected between the protruding bearing wheel core 1511 on both sides of the polyurethane rubber-coated bearing wheel 15 and the inner sides of the corresponding two fixed seat shaft clamps 112a2 and 112b2. The two limiting wheel axle sleeves 13 clamp the polyurethane rubber-coated bearing wheel 15 and will not shake. The outer polyurethane rubber layer of the polyurethane rubber-coated bearing wheel 15 will not contact the roller body 11, and the limiting wheel axle sleeve 13 will not contact the protruding shafts on both sides. The polyurethane rubber-coated bearing wheel 15 other than the wheel core 1511 is in contact with other parts, and the mechanical transmission performance of the polyurethane rubber-coated bearing wheel 15 is not affected. The roller 1 as a whole can maintain a straight line operation. The hanging arm 111 of the roller 1 extends out of the roller groove notch 211 of the track 2 and is suspended without contacting the track 2. When the track 2 is flipped at any angle, the curtain can be used normally after the roller 1 ring 12 is mounted on the curtain. The curtain has multiple functions. The roller hanging arm 111 of the roller 1 of the roller groove 21 of the track 2 extends out of the roller groove notch 211. When the roller hanging arm 111 and the track roller groove 21 are facing other directions except downward, the curtain covers the lower half A of the track 2 after the roller ring 12 is mounted on the curtain, which solves the light leakage problem between the track and the curtain in the prior art, and makes the curtain have shielding and privacy.

[0046] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions within the scope of the claims.
