Abstract
Description
Technical Field
[0001] This application relates to the technical field of doors and windows, and in particular to a louver slider drive structure in a closed environment. Background Technology
[0002] Venetian blinds are special window frames made of closely spaced, angled slats made of materials such as metal and wood. Their core functions are to regulate light, block views, and maintain ventilation. Precise control of light intensity is achieved through a slat angle adjustment mechanism. Utilizing advanced technology, the Venetian blinds are installed entirely within double-glazed windows and controlled magnetically. They can be easily raised, lowered, or flipped, saving space while achieving the purpose of sun shading.
[0003] In related technologies, hollow venetian blinds include an outer glass layer, an inner glass layer, and a frame. The outer and inner glass layers are set parallel to each other within the frame, and together with the frame, they form a cavity. The cavity contains venetian blinds, and a slider that controls the adjustment of the venetian blind slats is located on the inner glass layer. The venetian blinds are raised and lowered by manually controlling the slider to move up and down.
[0004] In practical use, it was found that, based on the fire protection requirements of buildings, a layer of fireproof glass needs to be added to the inner side of the hollow louver. This means that the slider switch of the hollow louver is located between the inner glass and the fireproof glass, that is, in a relatively sealed space. Operators cannot directly operate the slider of the hollow louver, which affects the use of the hollow louver. Summary of the Invention
[0005] In order to enable the slider to be operated even after the hollow louver is installed in an enclosed space, this application provides a louver slider driving structure in an enclosed environment, which has the effect of controlling the slider of the hollow louver in an enclosed space and improving the working efficiency of the slider.
[0006] The louver slider driving structure provided in this application adopts the following technical solution:
[0007] A louver slider driving structure for a closed environment includes a frame and a slider disposed in a cavity. The frame is provided with a handrail, and the handrail has a through hole corresponding to the position of the slider. The through hole communicates with the cavity. A steel pipe is provided on the handrail, and a connecting mechanism is provided on the slider. The steel pipe passes through the through hole and is connected to the slider through the connecting mechanism. By driving the steel pipe to move up and down, the slider can be raised and lowered within the frame.
[0008] By adopting the above technical solution, the steel pipe is first connected to the slider through a connecting mechanism, and then the lifting and lowering of the steel pipe can control the movement of the slider within the frame. This transforms the internal drive of the slider into an external, intuitive operation, allowing the slider to be raised and lowered even within the enclosed space of the frame, thereby adjusting the opening range of the louvers and effectively improving work efficiency.
[0009] Optionally, the connecting mechanism includes a connecting sleeve and a bolt. The connecting sleeve is fitted onto the outer wall of the slider, and the bolt passes through the connecting sleeve and is threadedly fixed to the connecting sleeve. The threaded portion of the bolt faces the through hole direction.
[0010] By adopting the above technical solution, the connecting sleeve can adapt to sliders of different shapes and sizes, and can achieve matching connection with a variety of sliders. By putting the connecting sleeve on the outer wall of the slider and then fastening it with bolts, it is easy to install.
[0011] Optionally, the bolt is provided with a locking element, and the bolt passes through the connecting sleeve and is threadedly connected to the locking element.
[0012] By adopting the above technical solution, the bolts are locked onto the connecting sleeve by the locking component, which can reduce the displacement or loosening of the bolts due to vibration or impact, thereby preventing the connection between the steel pipe and the slider from failing and effectively improving the stability of the connection between the steel pipe and the slider.
[0013] Optionally, both ends of the steel pipe are provided with threaded holes that mate with bolt threads.
[0014] By employing the above technical solution, the internal thread of the steel pipe mates with the bolt thread through a screwing mechanism, achieving a fixed connection between the steel pipe and the slider. The steel pipe then drives the slider to move up and down. A detachable connection is formed by the bolt passing through the bolt hole at the end of the steel pipe. After adjusting the opening width of the hollow louver, the steel pipe can be loosened and separated from the slider to retract, thus maintaining the aesthetic appeal of the structure.
[0015] Optionally, both ends of the steel pipe are threaded with sleeves, and the end of the sleeve away from the steel pipe is threadedly connected to a bolt.
[0016] By adopting the above technical solution, sleeves are fitted at both ends of the steel pipe, and one end of the sleeve is then threadedly connected to a bolt. This allows either end of the steel pipe to be inserted into the through hole to fix the steel pipe to the slider. Furthermore, if the sleeves become damaged or broken after long-term use, they can be replaced individually, effectively reducing maintenance costs.
[0017] Optionally, the central part of the sleeve is a solid rod, and the two ends are hollow internally threaded sleeves. The end of the steel pipe near the slider is provided with internal threads, and the steel pipe is threadedly connected to the sleeve.
[0018] By adopting the above technical solution, the hollow internal threads at both ends of the sleeve provide sufficient thread fit length for the connection between the bolt and the steel pipe, effectively enhancing the stability of the connection. The sleeve separates the part of the bolt that directly contacts the steel pipe, reducing the wear caused by the bolt and steel pipe abutting against each other inside the sleeve.
[0019] Optionally, the inner wall of the through hole is provided with an anti-wear layer.
[0020] By adopting the above technical solution, the wear-resistant layer helps to reduce the friction between the steel pipe and the inner wall of the through hole, thereby reducing the wear of the steel pipe and extending its service life.
[0021] Optionally, a plug may be included, which is embedded in the through hole to seal the through hole.
[0022] By adopting the above technical solution, the plug is filled into the through hole, effectively preventing external substances such as dust and debris from entering the frame through the through hole, thereby improving the cleanliness and stability of the frame.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. First, connect the steel pipe to the slider through the connecting mechanism, and then drive the steel pipe to lift and lower, which can control the slider to move within the frame. This transforms the internal drive of the slider into an external, intuitive operation, allowing the slider to be raised and lowered even within the enclosed space of the frame, thereby adjusting the opening range of the louvers and effectively improving work efficiency.
[0025] 2. After inserting the steel pipe into the through hole and aligning it with the bolt, tighten the steel pipe so that the internal thread of the steel pipe engages with the bolt thread, thus achieving a fixed connection between the steel pipe and the slider. The steel pipe can then drive the slider to move up and down. The bolt passes through the bolt hole at the end of the steel pipe, and the two form a detachable connection. After adjusting the opening range of the hollow louver, loosen the steel pipe and separate it from the slider to store the steel pipe, which helps to maintain the aesthetics of the structure.
[0026] 3. One end of the sleeve is connected to the steel pipe, and the other end is threaded to the bolt, which extends the height of the steel pipe. Both ends of the steel pipe are fitted with sleeves, so either end of the steel pipe can be inserted into the through hole to fix the steel pipe and the slider. At the same time, if the sleeve is damaged or broken after long-term use, it can be replaced separately, effectively reducing maintenance costs. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0031] Example 1:
[0032] Embodiment 1 of this application discloses a louver slider driving structure in a closed environment, referring to... Figure 1 The system includes a frame 1 and a slider 2 housed within a cavity 5. A handrail 3 is integrally formed on the frame 1, perpendicular to the direction of movement of the slider 2. A through hole 4 is provided through the handrail 3 corresponding to the position of the slider 2, communicating with the cavity 5 within the frame 1. A connecting mechanism 7 is provided on the slider 2, connecting it to a steel pipe 6. The end of the steel pipe 6 furthest from the connecting mechanism 7 passes through the through hole 4 and is located on the side of the handrail 3 furthest from the slider 2. By driving the steel pipe 6 up and down outside the frame 1, the lifting and lowering of the slider 2 inside the frame 1 can be controlled, thereby adjusting the opening range of the louvers and effectively improving the working efficiency of the slider 2.
[0033] Reference Figure 1 The connecting mechanism 7 consists of a connecting sleeve 71 and a bolt 72. The connecting sleeve 71 is fitted onto the outer wall of the slider 2, and the bolt 72 passes through the connecting sleeve 71 and is threadedly fixed to it, with the threaded portion of the bolt 72 facing the through hole 4. Both ends of the steel pipe 6 have threaded holes 8 that are compatible with the threads of the bolt 72. When it is necessary to control the movement of the slider 2, one end of the steel pipe 6 is passed through the through hole 4 and threadedly connected to the bolt 72, thus fixing the steel pipe 6 to the slider 2. Then, by driving the steel pipe 6 to move up and down, the opening range of the louvers can be adjusted by controlling the slider 2.
[0034] Reference Figure 1 A locking element 10 is provided on the bolt 72. In this embodiment, the locking element 10 is a locking nut. After the bolt 72 is threaded through the connecting sleeve 71, it is threadedly fixed to the locking nut, which further improves the stability of the bolt 72 fixed on the connecting sleeve 71.
[0035] Reference Figure 1A wear-resistant layer 11 is provided on the inner wall of the through hole 4, which can reduce the friction between the steel plate and the inner wall of the through hole 4 and reduce mechanical wear. A plug 12 that matches the through hole 4 is provided on the handrail frame 3, which can facilitate filling the through hole 4, prevent foreign objects from entering the cavity 5 inside the frame 1 through the through hole 4 and affecting the movement of the slider 2, and is conducive to the cleanliness and stable operation inside the frame 1.
[0036] The implementation principle of the louver slider drive structure disclosed in Embodiment 1 of this application is as follows: First, one end of the steel pipe 6 is passed through the through hole 4 and aligned with the bolt 72. Then, the steel pipe 6 is screwed to fix the steel pipe 6 and the bolt 72, thus fixing the steel pipe 6 and the slider 2. Finally, the steel pipe 6 is driven to move up and down outside the frame 1, which can synchronously drive the slider 2 to move up and down, thereby adjusting the opening range of the louver. This solves the problem of controlling the slider 2 in the sealed space of the hollow louver and effectively improves the working efficiency of the slider 2.
[0037] Example 2:
[0038] Embodiment 2 of this application discloses a louver slider driving structure in a closed environment. The difference between Embodiment 2 and Embodiment 1 is that, referring to... Figure 2 Both ends of the steel pipe 6 are threaded with sleeves 9, and both ends of the sleeves 9 are internally threaded. The end of the sleeve 9 furthest from the steel pipe 6 is threadedly fixed to the bolt 72. The threaded connection at both ends of the sleeves 9 achieves a fixed connection between the steel pipe 6 and the slider 2. Both ends of the sleeves 9 are detachably connected to the steel pipe 6 and the bolts 72. The sleeves 9 can also be used to fix the steel pipe 6 to the slider 2, and they are easy to replace individually, which reduces costs.
[0039] Reference Figure 2 The central part of the sleeve 9 is a solid rod, while the two ends are hollow and have internal threads. After the sleeve 9 is installed on one end of the steel pipe 6, the steel pipe 6 is then passed through the through hole 4, so that the other end of the sleeve 9 is connected to the bolt 72. The central part of the sleeve 9 can reduce the direct contact between the steel pipe 6 and the bolt 72, and reduce the wear caused by the steel pipe 6 and the bolt 72 abutting against each other inside the sleeve 9.
[0040] The implementation principle of the louver slider driving structure in a closed environment disclosed in Embodiment 2 of this application is as follows: First, the two ends of the steel pipe 6 are respectively threaded to the sleeve 9. Then, any end of the steel pipe 6 is passed through the through hole 4 and the sleeve 9 is threaded to the bolt 72, thus fixing the steel pipe 6 and the slider 2. Then, the steel pipe 6 is driven to move outside the frame 1, so the slider 2 can be controlled to move up and down synchronously, thereby driving the louver to adjust the opening range, effectively improving the working efficiency of the slider 2.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
