Description

Technical Field

[0001] The present invention relates to the technical field of engineering profiles, and specifically to a modular ultra-heavy pulley track combination. Background Art

[0002] The weight of an ultra-heavy sliding door can reach from 300 kg to 1000 kg. The pulleys on the existing sliding door guide rails cannot bear the weight of the ultra-heavy sliding door for a long time, resulting in difficult movement of the sliding door or even inability to move. The existing sliding door tracks are not modularly designed and cannot be disassembled or lengthened subsequently. The pulleys on the existing sliding door guide rails are not modularly designed either, and the number of installed pulleys cannot be adjusted according to the weight of the sliding door. The installation and replacement of the pulleys are also very cumbersome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a modular ultra-heavy pulley track combination with strong load-bearing capacity, adjustable load-bearing capacity, adjustable track length, and adjustable number and position of load-bearing wheels and retaining wheels of the pulley.

[0004] To achieve the above object, a modular ultra-heavy pulley track combination is designed, including a plurality of modular track profiles. On both sides of the modular track profile, there are respectively a first cavity and a second cavity with the same size and shape. In the middle of the modular track profile, there is a third cavity. On both sides of the bottom of the first cavity, the second cavity, and the third cavity, there are sliding grooves. At both ends of the first cavity and the second cavity, there are threaded holes; a plurality of modular load-bearing wheels are arranged in the first cavity and the second cavity of the modular track profile. The modular load-bearing wheel includes a wheel frame, and the outer shape of the wheel frame matches the first cavity and the second cavity. The wheel frame includes a wheel frame base and two vertically arranged wheel frame vertical plates. The cavity between the two wheel frame vertical plates is used to arrange the load-bearing wheel. Through holes are opened on the two wheel frame vertical plates, and a shaft pin passes through the through holes and the load-bearing wheel. The modular load-bearing wheel further includes an elastic waterproof pad. On both sides of the elastic waterproof pad, there are legs, and in the middle of the elastic waterproof pad, there is a through groove. The legs on both sides of the elastic waterproof pad are matched with the connecting grooves opened at the top of the wheel frame vertical plates; a plurality of modular retaining wheels are arranged in the third cavity of the modular track profile. The structure of the modular retaining wheel is the same as that of the modular load-bearing wheel, and the outer shape of the wheel frame of the modular retaining wheel matches the third cavity; a cover plate is provided with a plurality of through grooves. The cover plate is connected to the modular track profile, and a plurality of modular load-bearing wheels and a plurality of modular retaining wheels extend out from the through grooves of the cover plate.

[0005] The present invention also has the following preferred technical solutions:

[0006] 1. The bottom of the third cavity is not on the same horizontal plane as the bottoms of the first cavity and the second cavity, and a groove for mating and connecting door and window profiles is provided on the back of the third cavity.

[0007] 2. A V-shaped groove is provided in the middle of the bottoms of the first cavity, the second cavity, and the third cavity.

[0008] 3. An adjusting screw is provided on the threaded hole, and the adjusting screw is used to adjust the distance between the modular track profile and the door and window profile.

[0009] 4. It further includes a plurality of connecting plates and connecting racks. The connecting plates are matched with the bottom sliding grooves of the first cavity or the second cavity. The outer shape of the connecting racks is matched with the third cavity. A slider is provided at the bottom of the connecting racks and is matched with the bottom sliding groove of the third cavity. The connecting plates and the connecting racks are used to connect two adjacent modular track profiles.

[0010] 5. V-shaped protrusions are provided at the bottoms of the modular load-bearing wheels and the modular retaining wheels. The V-shaped protrusions of the modular load-bearing wheels and the modular retaining wheels are matched with the V-shaped grooves at the bottoms of the first cavity, the second cavity, and the third cavity.

[0011] 6. A V-shaped protrusion is provided at the bottom of the connecting rack, and the V-shaped protrusion of the connecting rack is matched with the V-shaped groove at the bottom of the third cavity.

[0012] Compared with the prior art, the advantages of the present invention are as follows:

[0013] 1. Multiple rows of most load-bearing wheels and retaining wheels are designed on the track profile. The number of load-bearing wheels and retaining wheels can be corresponding to the weight of the sliding door, and the outer diameter of the pulleys. The opening and closing force will be very light.

[0014] 2. Each group of load-bearing wheels and retaining wheels is provided with a structure matched with the sliding groove. Corresponding to the sliding groove structure on the track profile, the load-bearing wheels and retaining wheels can be directly inserted into the track profile one by one group. Each group of pulleys does not require fixing screws, saving the installation cost and the product processing cost.

[0015] 3. A limiting strip structure is designed. The limiting strip is inserted into the track profile. The distance between the load-bearing wheels and the retaining wheels is directly limited, and the front and back movement of the load-bearing wheels and the retaining wheels is limited. During installation, there is no need to measure the distance between each group of load-bearing wheels and retaining wheels, saving the installation cost, being more convenient and worry-free. Also, there is no need to worry about incorrect measurement or calculation of the distance between each group of load-bearing wheels and retaining wheels. The size of each limiting strip is accurate.

[0016] 4. A V-shaped groove is designed in the middle of the track profile and is matched with the V-shaped protrusions of the load-bearing wheels and the retaining wheels, which can automatically make the load-bearing wheels and the retaining wheels located at the center.

[0017] 5. A rubber sealing structure is designed on the load-bearing wheels and the retaining wheels, which can prevent water, dust, and garbage from entering.

[0018] 6. The track profile is designed with adjustment screws. By directly rotating the adjustment screws, the height of the track profile can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting screws 23 are used to adjust the distance between the modular track profile 1 and the door and window profile 20. The bottom of the third cavity 4 is not on the same horizontal plane as the bottoms of the first cavity 2 and the second cavity 3. As Figure 1 , 9 shown, on the back of the third cavity 4, there is a groove 21 for mating and connecting with the door and window profile 20.

[0032] As Figure 5 , 9 shown, the modular load - bearing wheels 7 are arranged in the first cavity 2 and the second cavity 3 of the modular track profile 1.
