Description

Structure of curtain track

This creation is about a curtain structure, especially a curtain track structure,

The conventional curtain structure is equipped with a retractable upper rail. Please refer to Figures 5, 6, and 7, the upper rail 30 has an inner rail 31 and an outer rail 32. The inner rail 31 and the outer rail 32 Both are hollow to form a channel 311, 321, and a slot 312, 322 is provided through the bottom of the channel, and two ends of the slot 312, 322 are horizontally provided with two guide rails 313, 323 for mounting The pulley 33 with the curtain slides and shifts, thereby achieving the opening and closing of the curtain.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: The above-mentioned conventional upper rail 30 structure, because the inner rail 31 and the outer rail 32 are nested and combined, make the guide The guide rails 313 and 323 will be stacked on each other, resulting in a high-low drop at the junction of the inner rail 31 and the outer rail 32. Therefore, when the pulley 33 is displaced between the inner rail 31 and the outer rail 32, it will be guided by The drop formed by the rails 313 and 323 affects the smoothness of the slide, which not only causes inconvenience in the use of the structure, but also generates noise, which is really necessary for improvement.

In view of this, the creator has many years of experience in manufacturing development and design of related products. In view of the above goals, after detailed design and prudent evaluation, the final creation is indeed practical.

The technical problem to be solved by this creation is to provide a curtain track structure in view of the above-mentioned deficiencies in the existing technology.

The track is provided with at least two rails in an inner and outer joint, a hollow channel is formed inside the rail, and a slot is provided at the center of the bottom of the rail to communicate with the hollow channel, and both sides of the slot They are all bent inwards and are provided with two vertical guide rails.

Preferably, a limiting groove is formed between the two sides of the hollow channel of the rail and the two vertical rails.

Preferably, the above-mentioned track provides the assembly of the pulley seat of the curtain. The wheel system of the pulley seat is stacked on the vertical guide rail and slides along the vertical guide rail to achieve the displacement state.

Both outer sides of the wheel body are provided with a limit guide plate, the outer diameter of the limit guide plate is greater than the outer diameter of the wheel body, and the two limit guide plates are arranged outside the two vertical guide rails to achieve the purpose of limiting the position of the wheel body .

Compared with the effect of the previous technology: the second of the rails is composed of inner and outer joints, so that when the curtain is packaged and shipped, one of the rails can be completely retracted into the other of the rails, which greatly reduces the volume of the rail , To reduce packaging and transportation costs, and the two rails are provided with vertical rails to provide sliding displacement of the wheel base of the pulley seat, through the above design, the two rails will not produce high and low drop, which helps to improve the smooth sliding displacement of the pulley seat Degree, reduce the probability of noise and damage failures, practical.

In order for your review committee to have a better understanding and understanding of the purpose, features and functions of this creation, the following is please cooperate with the [schematic description] detailed description as follows: first, please refer to the first and second figures, A curtain rail structure. The rail 10 is provided with at least two rail rods 11 in an inner and outer joint manner. A hollow channel 12 is formed inside the rail rod 11, and a notch 13 is provided at the center of the bottom of the rail rod 11 The hollow channel 12 communicates with each other, and both sides of the slot 13 are further bent inwardly to provide two vertical guide rails 14, and a limit groove is formed between the two sides of the hollow channel 12 and the two vertical guide rails 14 15.

For the composition and use of its structure, please refer to Figures 2, 3, and 4 again. The two rail rods 11 of the rail 10 are formed by the inner and outer joints, so that the rail 10 can be adjusted according to the size of the window. The rod 11 achieves a better length of use, and the track 10 mainly provides the assembly of the pulley seat 20 of the curtain structure. When the pulley seat 20 is installed, it is assembled from one end of the track 10 and spans between the two vertical guide rails 14, and the The wheel body 21 of the pulley base 20 is stacked on the vertical guide rail 14 so that the pulley base 20 is displaced by the wheel body 21 along the vertical guide rail 14, and the lower half of the pulley base 20 is penetrated by the slot 13 It is used for curtain installation. When the pulley base 20 slides and moves in the track 10, it can be used to open and close the curtain.

Furthermore, a limit guide 211 is provided on both outer sides of the wheel body 21, the limit The outer diameter of the guide plate 211 is greater than the outer diameter of the wheel body 21, and the two limit guide plates 211 are disposed outside the two vertical guide rails 14, and are respectively located in the limit groove portions 15 on both sides, thereby reaching the limit The purpose of the position of the wheel body 21.

With the structure of the above specific embodiment, the following benefits can be obtained: the rail 10 bis the rail rod 11 is composed of inner and outer joints, so that when the curtain is packaged and shipped, one rail rod 11 can be completely retracted The inside of the rail 11 greatly reduces the volume of the rail 10 and reduces the cost of packaging and transportation. The rail 11 provides the sliding displacement of the wheel body 21 of the pulley seat 20 by the vertical rail 14. The rail 11 does not produce a high-low drop, which helps to improve the smoothness of the sliding displacement of the pulley base 20, reduce the probability of noise generation and damage failure, and have practicality.

In summary, this creation has indeed reached a breakthrough structural design, and it has improved creative content, and at the same time it can achieve industrial utility and progress.
