Description

Technical Field

[0001] The present application relates to the technical field of curtain pulling, and in particular to a curtain pulling mechanism. Background Art

[0002] In cultural venues such as local chronicles museums, party history museums, and archives, curtains have become an indispensable shielding and separation tool to display exhibits and precious materials more vividly and accurately.

[0003] However, the traditional curtain operation method, whether it is completely dependent on manual or through the motor winding rope to pull the curtain, is inefficient and fragile. Manual operation is not only time-consuming and labor-intensive, but also improper operation can easily cause damage to the curtain, thus affecting the display effect; and the motor winding rope method, although it improves efficiency to a certain extent, still has problems such as inconvenient operation and noise interference. What is more noteworthy is that some traditional curtain pulling mechanisms will make abrupt noises at the moment of motor start and stop, which can easily break the quiet atmosphere of the exhibition area and cause great interference to the audience's visiting experience. Especially in those exhibition environments that need to maintain a high degree of quietness, this noise problem is particularly prominent, seriously reducing the audience's immersion and satisfaction. In addition, traditional curtain pulling mechanisms are usually equipped with complex transmission systems and control systems, which not only increases the difficulty of equipment maintenance, but also makes the maintenance cost continue to rise. In order to ensure the stable operation of the curtain mechanism, regular professional maintenance and maintenance are required, which undoubtedly increases the operating burden of the user unit. Moreover, once a failure occurs, due to the complexity of the mechanism structure, it is also quite difficult to repair, which may affect the normal operation of the exhibition hall and the audience's visiting experience.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Example

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , a curtain pulling mechanism, including a curtain board 1, which is not only the main support of the curtain pulling mechanism, but also a key component for bearing related curtain pulling components. The curtain board 1 is made of lightweight materials, such as aluminum, which makes the overall structure lighter and easier to carry and install. The advantage of this material is that it has sufficient strength and rigidity, and can greatly reduce the overall weight, thereby improving the portability and flexibility of the mechanism. In addition, in order to enhance the stability and durability of the curtain board 1, reinforcing ribs and support frames are added to its bottom. These reinforcing ribs and support frames can effectively disperse external loads and prevent the curtain board 1 from being deformed or damaged during long-term use, thereby extending the service life of the mechanism.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A curtain pulling mechanism comprises a driving mechanism 2 mounted on the surface of a curtain board 1, and a slideway mechanism 3 is provided on one side of the surface, a hook mechanism 4 is provided at the movable end of the driving mechanism 2, a protective mechanism 5 is bolted to the side wall of the curtain board 1, and the outer wall of the protective mechanism 5 has three fixing blocks 6, the driving mechanism 2 comprises a driving motor 21, a driving wheel 22, a driven wheel 23, a transmission rope 24, a bearing 25, a locking bolt I 26 and a locking bolt II 27; the slideway mechanism 3 comprises a slideway groove 31 and a card groove 32; the hook mechanism 4 comprises a plurality of curtain hooks 41, a traction hook 42, a plurality of sliding holes 43, two limit rings 44 and a plurality of sliding balls 45; the protective mechanism 5 comprises a top plate 51, a side plate 52 and a protective cover 53.

[0027] Among them, the design of the driving mechanism 2 enables the hook mechanism 4 to slide along the slide mechanism 3. The driving motor 21 is used to drive the driving wheel 22 to rotate, and a high-efficiency and low-noise DC brushless motor is selected. This motor has the characteristics of fast response speed, stable torque and low running noise. In addition, the motor has built-in overheat protection and overload protection functions to ensure that it can automatically cut off the power during long-term operation or abnormal conditions to prevent motor damage. The driving wheel 22 and the driven wheel 23 are made of engineering plastic materials with strong wear resistance, and the surface is specially treated to increase the friction between the transmission rope 24, ensuring higher transmission efficiency and not easy to slip. At the same time, the wheel shaft parts of the driving wheel 22 and the driven wheel 23 are made of high-strength alloy materials, which improves the overall load-bearing capacity and service life. The transmission rope 24 is made of high-strength, wear-resistant synthetic fiber material with excellent elasticity and tensile strength. In addition, the surface of the transmission rope 24 is covered with an anti-skid layer to ensure that the connection with the hook mechanism 4 is more stable and reliable. The bearing 25 adopts a precision-made rolling bearing, which has the characteristics of low friction and flexible rotation, and can reduce the resistance of the driven wheel during rotation and improve the transmission efficiency. The locking bolts Ⅰ26 and Ⅱ27 are made of high-strength stainless steel, and the surface is treated with anti-corrosion to ensure that they are not easy to rust and loosen during long-term use. In addition, the locking bolts adopt a special thread design, and the connection with the output end of the drive motor 21 and the surface of the curtain board 1 is more firm and reliable. The drive mechanism 2 can also be integrated with an intelligent control module to realize functions such as remote control, timer switch, and speed adjustment. Users can operate the curtain mechanism through a mobile phone APP or a remote control, which improves the convenience and flexibility of use.

[0028] The design of the slide mechanism 3 facilitates the sliding of the hook mechanism 4. The interior of the slide groove 31 is rounded, forming a certain angle, so that the hook mechanism 4 is not easy to fall off during the sliding process. At the same time, the interior of the slide groove 31 and the card groove 32 are smoothed to reduce the friction coefficient and improve the sliding smoothness.

[0029] Among them, the hook mechanism 4 is designed to hang and take the curtain. The curtain hook 41 and the traction hook 42 are made of high-strength lightweight alloy material, which not only ensures sufficient load-bearing capacity but also reduces the overall weight. At the same time, their surfaces are specially treated, such as spraying an anti-skid coating, which increases the friction between the curtain and the curtain to prevent the curtain from slipping during movement. In addition, the shape and size of the curtain hook 41 and the traction hook 42 can be customized according to different curtain types and requirements, such as increasing the number of hooks, adjusting the hook spacing, etc., to adapt to curtains of different sizes and shapes. The design of the sliding hole 43 takes into account the smoothness and stability of sliding. The edge of the hole is smoothed to reduce the friction with the transmission rope 24. The sliding ball 45 is made of wear-resistant, low-friction coefficient material, such as nylon or polytetrafluoroethylene, to ensure that it can remain stable and not easy to wear during the sliding process. In order to further enhance the sliding performance, a lubricant or a lubricating coating can also be added between the slideway groove 31 and the sliding ball 45 to further reduce friction and improve sliding efficiency. The function of the limit ring 44 is to ensure that the traction hook 42 is stable on the transmission rope 24.

[0030] Among them, the traction hook 42 and the curtain hook 41 are designed as an integrated whole with the sliding ball 45. The top of the sliding ball 45 is directly connected to the inner top of the traction hook 42 and the curtain hook 41 through a casting or injection molding process to form an integral structure. This design not only enhances the stability of the structure, but also simplifies the assembly process and improves production efficiency. The openings opened on the side walls of the traction hook 42 and the curtain hook 41 are optimized so that the curtain can be mounted and unmounted more easily during the hooking process. The shape and size of the opening are customized according to the type and thickness of the curtain to ensure that the hook mechanism can adapt to different types of curtains.

[0031] Among them, the protective mechanism 5 is used to protect the driving mechanism 2 and the hook mechanism 4, ensuring their stable operation and extending their service life. The top plate 51, the side plate 52 and the protective cover 53 are all made of high-quality sound-absorbing materials. They are not only sturdy in structure, but also can effectively absorb the noise generated by the driving motor 21 during operation, creating a quieter use environment for users. These protective components are tightly fixed to the side wall of the curtain board 1 by bolts, which is not only convenient to install, but also ensures the stability of the entire mechanism. It is particularly worth mentioning that the protective cover 53 not only covers the driving motor 21, but also includes other key components such as the driving mechanism 2 and the control module into its protection range according to actual needs, forming an all-round protective barrier.

[0032] The top plate 51, the side plate 52 and the protective cover 53 are designed as an integrated structure, which not only simplifies the assembly process and improves production efficiency, but also enhances the structural strength and stability of the entire protective mechanism. The integrated design reduces the connection points between components and reduces the risk of problems caused by loose or broken connections.

[0033] The design of the fixing block 6 facilitates fixing the device at a predetermined position.

[0034] The working principle of the curtain-drawing mechanism: when in use, the user first uses the fixing block 6 to firmly fix the device at a predetermined position. Then, the curtains are hung on a number of curtain hooks 41 and traction hooks 42, ready for display. Once the drive motor 21 receives the start signal, it starts working immediately. The drive motor 21 drives the driving wheel 22 to rotate and closely cooperates with the driven wheel 23, so that the transmission rope 24 can move smoothly. The movement of the transmission rope 24 then drives the traction hook 42 to slide along the slide mechanism 3, and the traction hook 42 pulls a number of curtain hooks 41 to move together, thereby achieving the purpose of pulling the curtain to unfold. When the curtain needs to be retracted, the drive motor 21 will rotate in the opposite direction. As the drive motor 21 reverses, the traction hook 42 will move in the opposite direction of the curtain unfolding. In this process, a number of curtain hooks 41 fold each other, so that the curtain gradually closes. Through this principle, the curtain-drawing mechanism can easily realize the unfolding and folding of the curtain.

[0035] It should be noted that the specific models and specifications of the drive motor 21, the active wheel 22, the driven wheel 23, the transmission rope 24, and the bearing 25 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the driving motor 21 are clear to those skilled in the art and will not be described in detail here.

[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
