Description

Technical Field

[0001] The utility model relates to the technical field of curtain beams, in particular to a beam structure of a day-night dual-purpose honeycomb curtain. Background Art

[0002] The traditional day-night dual-purpose honeycomb curtain includes two different types of curtain fabrics, a top beam, a middle beam, a bottom beam, and a winding mechanism for winding the curtain. One of the two different types of curtain fabrics is suitable for daytime and is installed between the top beam and the middle beam, while the other is suitable for night and is installed between the bottom beam and the middle beam. In the traditional honeycomb curtain, the curtain cords are inserted into the bottom beam and the middle beam and connected to the internal linkage mechanism. Through slots are provided at both ends of the traditional bottom beam and both ends of the middle beam to communicate with the inside of the beam for placing the linkage mechanism or other components. When assembling the curtain, a cover plate is provided on the through slot to seal the through slot, and bolts are connected between the cover plate and the through slot to ensure stable connection between the cover plate and the through slot. The above structure has many drawbacks. For example, when the curtain cord winding fails or one-sided curtain cords are wound too much, it is necessary to adjust the connection position between the curtain cords and the linkage mechanism, that is, to adjust the relative height of the curtain cords. However, adjusting the curtain cords of the traditional beam requires removing the cover plate and pulling out the internal linkage mechanism of the beam through the through slot, that is, the entire curtain needs to be removed. The entire removal efficiency is low and requires re-assembly, making the entire adjustment more cumbersome. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a beam structure of a day-night dual-purpose honeycomb curtain to solve the problem that it is difficult to quickly adjust the curtain cords and their linkage mechanism in the beam of the traditional day-night dual-purpose honeycomb curtain.

[0004] To achieve the above object, the utility model provides a beam structure of a day-night dual-purpose honeycomb curtain, which includes a plurality of beams. A connection groove for installing external curtain leaves is formed between adjacent beams. A receiving groove for accommodating the cord winding mechanism of the external curtain runs through the beam along the length direction of the beam. A plurality of through holes for the curtain cords of the external curtain to penetrate into the receiving groove are formed in the beam. The opening direction of the through holes is perpendicular to the length direction of the beam. The receiving groove communicates with the side wall of the beam and forms a slotted opening. Both ends of the slotted opening communicate with the outer walls of both ends of the beam and form sliding openings. A baffle for closing or exposing the slotted opening is slidably arranged on the slotted opening. A limiting member for preventing the baffle from disengaging from the slotted opening along the opening direction of the slotted opening is arranged at the opening of the slotted opening.

[0005] The advantages of adopting the above technical solution are as follows: When it is necessary to adjust the cord and its linkage mechanism inside the receiving groove, only the baffle needs to be slid out along the length direction of the slot through the sliding opening to expose the slot. Then, the connection position between the cord and the linkage mechanism can be adjusted through the slot to correct the height position of the cord. That is, when there is a position deviation or height deviation of the unilateral cord relative to the adjacent cord, the baffle can be removed to adjust the cord, thereby realizing the rapid adjustment of the cord. The entire adjustment process is fast and efficient. Furthermore, when the position of the cord deviates, it is not necessary to remove the entire curtain, thus improving the adjustment efficiency. The setting of the limiting member in the above technology prevents the baffle from detaching from the slot along the opening direction of the slot, thereby avoiding the failure of the baffle to close the slot. In the above technology, one of the two beam bodies is the middle beam, and the other is the bottom beam.

[0006] The present utility model is further provided as follows: The limiting member includes two oppositely arranged limiting plates. The two limiting plates are respectively arranged on the inner walls of both sides of the slot. The outer walls of the two limiting plates are bent with limiting edges towards the opening of the slot. The radial cross-section of the limiting edge is arranged in an arc shape, and the arc direction faces the inner wall of the slot. The combination of the inner peripheral wall of the limiting edge, the inner wall of the slot, and the outer wall of the limiting plate forms a limiting groove. The opening direction of the limiting groove is arranged to be consistent with the opening direction of the receiving groove, and both ends of the limiting groove are communicated with the adjacent sliding openings respectively. Both ends of the baffle are bent with blocking edges. The radial cross-section of the blocking edge is arranged in an arc shape. The shape of the blocking edge is adapted to the shape of the limiting groove, and the blocking edge is in snap-fit with the limiting groove. The outer peripheral wall of the blocking edge is respectively in contact with the outer wall of the limiting plate and the inner wall of the slot. The inner peripheral wall of the blocking edge is in contact with the inner peripheral wall of the limiting edge.

[0007] The advantages of adopting the above technical solution are as follows: When the baffle is inserted into the slot through the sliding opening, the blocking edge on the baffle is synchronously inserted into the limiting groove through the sliding opening. When the baffle is completely inserted and fitted with the slot, the outer peripheral wall of the blocking edge is respectively in contact with the outer wall of the limiting plate and the inner wall of the slot, and the inner peripheral wall of the blocking edge is in contact with the inner peripheral wall of the limiting edge. Also, because the radial cross-sections of both the blocking edge and the limiting plate are arranged in an arc shape, the blocking edge and the limiting plate are hooked and cooperated with each other, making it difficult for the baffle to detach from the slot along the opening direction of the slot, thereby realizing the closure of the slot by the baffle and further preventing external impurities from entering the receiving groove through the slot. In the above technology, the baffle can be inserted and fitted with or separated from the slot by sliding along the length direction of the beam body, improving the disassembly and assembly efficiency of the baffle, and further improving the adjustment efficiency of the part of the cord in the receiving groove.

[0008] The present utility model is further provided as follows: The outer wall of the limiting plate and the inner wall of the slot are connected by a smooth arc surface and form a mating surface. The mating surface is in contact with the outer peripheral wall of the blocking edge.

[0009] The advantages of adopting the above technical solution are as follows: In the above technology, the mating surface is provided to improve the fitting strength of the rib in the limiting groove, thereby improving the adaptability between the rib and the limiting groove and the stability of the rib in the limiting groove.

[0010] The present utility model is further provided that: Bent portions are formed on the top wall or the bottom wall or both the top wall and the bottom wall of the beam body. The two bent portions are arranged oppositely, and a clamping groove for clamping the end portion of the external curtain blade is formed between the inner peripheral wall of the bent portion and the beam body.

[0011] The advantages of adopting the above technical solution are as follows: In the above technology, the clamping groove is provided for the connection between the curtain and the beam body, thereby improving the clamping strength and installation efficiency between the curtain and the beam body; in the above technology, bent portions are provided on both the top wall and the bottom wall of the middle beam for the connection and installation of the middle beam with two external curtain fabrics, and a bent portion is provided on the top wall of the bottom beam for the bottom beam to cooperate with the middle beam for installing the curtain fabric between the bottom beam and the middle beam.

[0012] The present utility model is further provided that: The perforation is arranged at a position between the two bent portions.

[0013] The advantages of adopting the above technical solution are as follows: In the above technology, the perforation is located between the two bent portions, that is, the perforation is opened in the middle of the beam body, so that the cord passes through the beam body in the middle position of the curtain fabric. In the traditional honeycomb curtain fabric, the cord passes through several curtain sheets of the honeycomb curtain fabric, that is, it is exposed outside the honeycomb curtain fabric and is extremely vulnerable to external stress and prone to breakage, resulting in the failure of the curtain fabric to roll up. In this technology, the cord is located inside the honeycomb curtain fabric due to the position of the perforation, that is, the cord is no longer exposed, thereby avoiding the breakage of the cord due to external stress and improving the aesthetics at the same time.
