Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb curtains, in particular to a beam structure of a double-curtain honeycomb curtain. Background Art

[0002] The traditional day and night dual-use honeycomb curtains include two different types of curtains, a top beam, a middle beam, a bottom beam and a rolling mechanism for rolling up the curtains. One of the two different types of curtains 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. The cords of the traditional honeycomb curtains are inserted into the bottom beam and the middle beam and connected with the internal linkage mechanism. Through grooves are provided at both ends of the traditional bottom beam and the middle beam to communicate with the interior of the beam body so as to place the linkage mechanism or other components. When the curtains are assembled, a cover plate is provided on the through groove to seal the through groove, and bolts are connected between the cover plate and the through groove so as to ensure a stable connection between the cover plate and the through groove. However, when the above structure is used, when the cord winding fails or the single-side cord is wound too much, it is necessary to adjust the connection position of the cord and the linkage mechanism, that is, adjust the relative height of the cord. However, the traditional beam body needs to remove the cover plate and pull the linkage mechanism inside the beam body out of the beam body through the through groove to adjust the cord, that is, the entire curtain needs to be dismantled, the entire dismantling efficiency is low and reassembly is required, making the entire adjustment more cumbersome. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a beam structure for a double-curtain honeycomb curtain, which solves the problem that the connection between the cord and the linkage mechanism in the beam structure of the traditional double-curtain honeycomb curtain is difficult to adjust quickly.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a beam structure of a double-curtain honeycomb curtain, including a beam, a receiving groove for accommodating an external winding mechanism penetrating the beam along its length direction, a plurality of through holes for external curtain cords to pass into the receiving groove and cooperate with the winding mechanism are opened on the beam, the receiving groove is connected to the side wall of the beam and forms a through groove, a sealing plate for closing or exposing the through groove is slidably arranged on the side wall of the beam along the length direction of the beam, a limiting member for preventing the sealing plate from separating from the beam along the direction in which the through groove is opened is arranged on the side wall of the beam, and an adsorption member for adsorbing the sealing plate to keep it in a relatively fixed state when the sealing plate closes the through groove is arranged on the side wall of the beam.

[0005] The advantages of adopting the above technical scheme are as follows: when it is necessary to adjust the cords and their linkage mechanism inside the receiving groove, the adsorption of the sealing plate by the adsorption member is first cancelled, and then the sealing plate is slid in the length direction of the beam body so that the sealing plate no longer closes the through groove. At this time, the through groove is exposed, and then the connection position of the cord and the linkage mechanism is adjusted through the through groove to realize the correction of the height position of the cord, that is, when a single-sided cord has a position deviation or a height deviation relative to an adjacent cord, the baffle can be removed to realize the adjustment of the cord, thereby realizing the rapid adjustment of the cord, and the whole adjustment process is fast and efficient, and thus when the cord position deviates, there is no need to remove the entire curtain, thereby improving the adjustment efficiency; after the adjustment is completed, the sealing plate is slid along the length direction of the beam body so that the sealing plate completely covers the opening of the through groove, and then the two ends of the sealing plate are adsorbed by the adsorption member, thereby realizing the fixation of the sealing plate on the beam body, and at the same time, the setting of the limit member in the above technology prevents the sealing plate from leaving the through groove along the opening direction of the through groove, thereby preventing the sealing plate from failing to close the through groove.

[0006] The utility model is further provided with: the limit member includes two limit grooves opened along the length direction of the beam body, the limit grooves are connected to the two ends of the beam body and form a sliding mouth, the two limit grooves are respectively arranged on the upper and lower sides of the through groove opening, the closing plate is provided with a plug plate corresponding to the two limit grooves, which is used to be placed in the limit groove through the sliding mouth and plug-in cooperate with the limit groove, an anti-slip groove is opened on the inner wall of the limit groove, the radial cross-section of the anti-slip groove is circular, the diameter of the anti-slip groove is larger than the width diameter of the limit groove, the shape of the plug plate is adapted to the limit groove, and a clamping part for clamping and cooperating with the anti-slip groove is provided at the front end of the plug plate, the clamping part has a circular radial cross-section and the shape of the clamping part is similar to the shape of the anti-slip groove.

[0007] The advantages of adopting the above technical scheme are as follows: the sealing plate is slid along the length direction of the beam body so that the plug plate is inserted into the limit groove through the sliding mouth. At this time, the plug plate is plugged into and matched with the limit groove, and the anti-slip groove and the clamping part are also clamped and matched. After the sealing plate completely closes the through groove, the anti-slip groove diameter is larger than the limit groove width diameter, so that the clamping part cannot slip out through the limit groove, thereby making it impossible for the plug plate to slip out of the limit groove along the opening direction of the limit groove, thereby limiting the sealing plate, making it impossible for the sealing plate to slip out of the beam body along the opening direction of the through groove, thereby achieving the sealing of the through groove by the sealing plate. That is, during daily use, if the user does not pull out or slide the sealing plate along the length direction of the beam body, the sealing plate always remains in a state of closing the through groove and the sealing plate will not slip out along the opening direction of the through groove to separate from the beam body; the above-mentioned technical setting improves the stability of the sealing plate on the beam body, and at the same time avoids the sealing plate and the beam body from being separated when the sealing plate is not driven to move, causing external impurities or liquids to invade the containing groove through the through groove; in the above-mentioned technology, the radial cross-section of the anti-slip groove and the radial cross-section of the clamping part are both circular, compared with the square structure, the curtain shakes under the influence of external wind factors, resulting in frequent collisions between the corners of the anti-slip groove and the corners of the clamping part and generating loud noise. This technology ensures that the anti-slip groove and the clamping part are clamped together and will not generate loud noise or frequent noise under long-term use. At the same time, it ensures that the clamping part will not shake or loosen in the anti-slip groove, thereby avoiding failure of the clamping part and the anti-slip groove.

[0008] The utility model is further configured as follows: the length of the sealing plate is greater than the length of the through slot, the adsorption component includes two adsorption blocks embedded in the side walls of the beam body, the two adsorption blocks are respectively arranged on the left and right sides of the through slot opening, the adsorption blocks are made of magnetic material and the two adsorption blocks are respectively magnetically matched with the two ends of the sealing plate.

[0009] The benefits of adopting the above technical solution are: when the sealing plate completely closes the through groove, the two ends of the sealing plate correspond to the positions of the two adsorption blocks one by one and cooperate with each other magnetically, thereby improving the connection strength between the sealing plate and the beam body and the connection stability of the sealing plate on the beam body; in the above technology, the sealing plate can be embedded with magnets according to production requirements or the sealing plate can be directly made of metal material, thereby ensuring that the sealing plate can be magnetically cooperated with the adsorption blocks; the setting of the adsorption blocks in the above technology ensures that when the curtain is affected by external factors such as wind force or stress loading, the sealing plate can still be stably set on the beam body, instead of sliding along the length direction of the beam body, thereby avoiding separation of the sealing plate from the beam body, and at the same time, when the user needs to move the sealing plate, he only needs to push the sealing plate, that is, push the sealing plate with a force greater than the magnetic adsorption force to achieve the sliding of the sealing plate along the length direction of the beam body.

[0010] The utility model further provides that: two connecting parts are bent on the top wall or the bottom wall or both the top wall and the bottom wall of the beam body, the two connecting parts are arranged opposite to each other and a groove for clamping the end of the external curtain fabric is formed between the inner peripheral wall of the connecting part and the beam body.

[0011] The advantages of adopting the above technical solution are as follows: the provision of the card slot in the above technology facilitates the connection between the curtain and the beam body, thereby improving the card connection strength and installation efficiency between the curtain and the beam body; if the beam body is a middle beam, the top wall and the bottom wall of the middle beam are provided with connecting parts, so that the middle beam can be connected and installed with two curtains outside; if the beam body is a bottom beam, the top wall of the bottom beam is provided with a connecting part, so that the bottom beam cooperates with the middle beam so that the curtain can be installed between the bottom beam and the middle beam.

[0012] The utility model is further arranged that: the through hole is arranged between the two connecting parts.

[0013] The advantages of adopting the above technical solution are as follows: in the above technology, the perforation is located between the two connecting parts, that is, the perforation is opened in the middle of the beam body, so that the cord is located in the middle of the curtain cloth and penetrates into the beam body. The cord of the traditional honeycomb curtain cloth passes through several curtain pieces of the honeycomb curtain cloth, that is, it is exposed outside the honeycomb curtain cloth, and is very easy to be affected by external stress and break, resulting in failure of the curtain cloth to be rolled up. However, the cord of the present technology is affected by the position of the perforation and is located inside the honeycomb curtain cloth, that is, the cord is no longer exposed, thereby avoiding the cord from being affected by external stress and breaking, and at the same time improving the aesthetics.
