Description

Technical Field

[0001] The present invention relates to the technical field of blinds, and more particularly to a single-side controlled double-glazed built-in blind. Background Art

[0002] In the field of building shading, single-side controlled double-glazed internal blinds are widely used due to their aesthetic and practicality. By placing a blind structure within the double-glazed area and using an external control device to raise, lower, and flip the blind, they effectively adjust indoor light and privacy while avoiding the dust accumulation and difficulty of cleaning associated with traditional curtains. This also improves the building's overall energy efficiency.

[0003] Currently, single-side controlled double-glazed internal Venetian blinds on the market still have numerous drawbacks that need to be addressed. Among these, significant deficiencies exist in the blind's drive structure, particularly regarding the coordination between the rotating shaft and the support base. Specifically, existing support bases typically feature semicircular notches on both sides of the top. This structure creates a large contact area between the rotating shaft and the support base as it rotates, significantly increasing friction during rotation.

[0004] The greater friction not only requires the user to apply greater force when driving the blinds through the unilateral control device, making the operation very strenuous and reducing the convenience and comfort of use; but also the rotating shaft and support seat are prone to wear due to long-term high friction, affecting their service life and stability, thereby increasing the maintenance cost and replacement frequency of the product. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a single-side controlled double-glazed built-in blind that can reduce the friction of the rotating shaft.

[0006] To achieve the above object, the present invention provides the following technical solutions: The present invention is further configured as follows: it includes a frame assembly, a plurality of blinds arranged on the frame assembly, a pulley slide mechanism arranged on the frame assembly, and a fixer iron bar arranged at the output end of the pulley slide mechanism. The single-sided controlled double-glazed built-in blinds also include a support mechanism, a flexible connection mechanism, a split mounting mechanism, an infinite flip mechanism and a tension adjustment mechanism; the support mechanism is arranged on the frame assembly, and the support mechanism includes a support seat and a rotating shaft; the support seat has a pair and is respectively arranged under the frame assembly, and the pair of support seats are spaced apart; the rotating shaft is rotatably arranged on the top of the support seat, and an opening for the fixer iron bar to pass through is opened in the middle of the rotating shaft, and one side of the rotating shaft is rotatably connected to the frame assembly; the flexible connection mechanism is arranged at the output end of the pulley slide mechanism, and the flexible connection mechanism is used to connect the fixer iron bar to the output end of the pulley slide mechanism; the split mounting mechanism is arranged on the side of the frame assembly; the infinite flip mechanism is arranged on the frame assembly, and the infinite flip mechanism is used to connect with the fixer iron bar; the tension adjustment mechanism is arranged on the side of the frame assembly, and the tension adjustment mechanism is used to adjust the tension of the rope.

[0007] By adopting the above technical solution, the problems of large friction and laborious rotation when the rotating shaft rotates on the support seat in the prior art are solved, and the friction generated when the rotating shaft rotates on the support seat is reduced, ensuring the stable rotation of the rotating shaft and the fixer iron bar, avoiding rotation deviation of the fixer iron bar and saving effort is achieved.

[0008] The present invention is further configured as follows: an opening is provided on one side of the top of the support seat for the rotating shaft to pass through and rotate, and the opening is a semicircular structure.

[0009] By adopting the above technical solution, in order to reduce the rotational friction of the rotating shaft on the top of the support base, the structure on the other side of the top of the support base is a U-shaped protrusion structure, and the U-shaped protrusion structure does not contact the outer side of the rotating shaft. The U-shaped protrusion structure is spaced apart from the outer side of the rotating shaft, so it does not affect the rotation of the rotating shaft.

[0010] The present invention is further configured as follows: the flexible connection mechanism includes a first connection part; the first connection part is arranged on the frame assembly, a slot connected to the pulley slide mechanism is opened on the side of the first connection part, and the first connection part is abutted and connected to the output end of the pulley slide mechanism through the slot; and the first connection part is a cylindrical structure.

[0011] The present invention is further configured as follows: the flexible connection mechanism also includes a second connection part; the second connection part is slidably arranged on the side of the rotating shaft, and a contact groove directly connected to the rotating shaft and the fixer iron bar is opened on the side of the second connection part, and the second connection part is a cylindrical structure, and the outer diameter of the second connection part is larger than the outer diameter of the first connection part.

[0012] The present invention is further configured as follows: the flexible connection mechanism also includes a first telescopic spring; the first telescopic spring is arranged on the first connection part, one end of the first telescopic spring is fixed to the first connection part, and the other end of the first telescopic spring is fixed to the second connection part, and the first telescopic spring is located between the first connection part and the second connection part. When the distance between the second connection part and the first connection part is extended, the first telescopic spring is in a stretched state.

[0013] By adopting the above technical solution, since the first connecting part and the second connecting part are connected by the first telescopic spring, even if the rope pulley slide rail mechanism produces position deviation during the installation process of the worker, it will not affect the rotation drive of the rotating shaft and the fixer iron bar, and there will be no difficulty in use.

[0014] The present invention is further configured as follows: the split installation mechanism includes a first split plate, a second split plate and a sliding cover plate; the first split plate is arranged next to the frame assembly, and the first split plate is used to install the rope pulley slide rail mechanism; the second split plate is slidably arranged on the top of the first split plate, and the second split plate can slide and be in abutment with the top of the first split plate; the sliding cover plate is slidably arranged on the top of the second split plate, and can be in abutment with the top of the second split plate when the sliding cover plate descends.

[0015] By adopting the above technical solution, when the installed sheave rail mechanism needs to be inspected and repaired, the worker only needs to remove the sliding cover plate from the outside of the second split plate to quickly inspect the sheave rail mechanism. This avoids the time-consuming and labor-intensive installation of the sheave rail mechanism with the traditional integrated first and second split plates, and the inconvenience of having to remove the second split plate after installation to inspect the sheave rail mechanism.

[0016] The present invention is further configured as follows: the infinite flip mechanism includes a fixed seat and an abutting rotating shaft; the fixed seat has a pair and is respectively arranged on the frame assembly, and the top of the fixed seat is provided with an opening for the rotating shaft to pass through and rotate; the abutting rotating shaft is rotatably arranged on the top of the fixed seat.

[0017] By adopting this technical solution, the rope pulley slide mechanism rotates and drives the abutting rotating shaft into rotation through the flexible connection mechanism. This rotation is unlimited, meaning it can rotate infinitely in one direction. Because the friction between the wire and the abutting rotating shaft is low, the abutting rotating shaft can open or close the shutter body through the wire.

[0018] The present invention is further configured as follows: the infinite flip mechanism also includes a limiting part; the limiting part has a pair and is respectively arranged on the outside of the abutting rotating shaft, and the pair of limiting parts are both conical structures, which can make the limiting parts rotate synchronously when the abutting rotating shaft rotates.

[0019] The present invention is further configured as follows: the tensioning adjustment mechanism includes a positioning part, a linear guide rail and a sliding part; the positioning part is arranged at the bottom of the frame assembly; the linear guide rail is arranged beside the positioning part, and the linear guide rail is a cylindrical structure; the sliding part is slidably arranged on the outside of the linear guide rail.

[0020] The present invention is further configured as follows: the tensioning adjustment mechanism also includes a rotating wheel and a second telescopic spring; the rotating wheel is rotatably arranged next to the sliding part; the second telescopic spring is arranged on the outside of the linear guide rail, one end of the second telescopic spring is fixed to the positioning part, and the other end of the second telescopic spring is fixed to the sliding part. When the sliding part slides in a direction close to the rope pulley slide rail mechanism, the second telescopic spring is in a compressed state.

[0021] By adopting the above technical solution, the rope is always kept in a stretched state after installation, ensuring that the rope pulley slide rail mechanism can achieve continuous stretching of the rope through the coordinated action of the sliding part and the rotating wheel, thereby ensuring the stable realization of normal driving of the rope, slide rail and rope pulley slide rail mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By setting up a support mechanism, the problem of large friction and laborious rotation when the rotating shaft rotates on the support seat in the prior art is solved, and the friction generated when the rotating shaft rotates at the support seat is reduced, ensuring the stable rotation of the rotating shaft and the fixer iron bar, avoiding rotation deviation of the fixer iron bar and saving effort is achieved.

[0023] By providing a flexible connection mechanism, if the pulley rail mechanism and the retainer bar become misaligned during assembly, the rotational force driven by the pulley rail mechanism to rotate the retainer bar will be transmitted through the first connection part, the first telescopic spring, and the second connection part. Because the first and second connection parts are connected by the first telescopic spring, when the pulley rail mechanism drives the first connection part to rotate, the rotational force is transmitted through the first telescopic spring to the second connection part and the rotating shaft, thereby driving the retainer bar to rotate.

[0024] By providing a split installation mechanism, workers install the pulley rail mechanism onto the frame assembly through the fixing portion and then press the sliding cover onto the top of the second split plate. Once the second split plate has been slidably installed with the first split plate, abutment grooves are formed on the tops of the first and second split plates, allowing the sliding cover to be pressed into place. The worker then slides and presses the sliding cover onto the second split plate. This avoids the time-consuming and labor-intensive installation of the pulley rail mechanism associated with traditional integrated first and second split plates, as well as the inconvenience of having to disassemble the second split plate after installation to inspect and repair the pulley rail mechanism.

[0025] By setting the unlimited turnover mechanism, the rope pulley slide rail mechanism rotates and drives the abutting rotating shaft to a rotating state through the flexible connection mechanism. And it can rotate unlimitedly, that is, it can rotate unlimitedly in one direction. Because the friction between the wire and the abutting rotating shaft is small, the abutting rotating shaft realizes the opening or closing of the shutter body through the wire.

[0026] By setting the tension adjusting mechanism, the problem of the rope being relaxed due to the elongation caused by long-term use and thus being difficult to drive the slide rail to move is solved, and the situation of abnormal slide rail sliding and rope pulley slide rail mechanism driving failure caused by position deviation during manual assembly of the rope pulley slide rail mechanism is avoided. The rope is wound outside the rotating wheel and connected to the upper and lower ends of the slide rail, and then connected with the rope pulley slide rail mechanism. When the rope is connected with the rotating wheel and the sliding part, the sliding part needs to be ensured to be in the middle position of the linear guide rail, so that the rope pulley slide rail mechanism can realize continuous stretching of the rope through the cooperation of the sliding part and the rotating wheel, thereby ensuring the stable realization of normal driving of the rope, the slide rail and the rope pulley slide rail mechanism.

DETAILED DESCRIPTION

[0029] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0030] It should be noted that all the technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs, unless otherwise specified.

[0031] Please refer to Figure 1-13 The present application provides the following technical solutions: Embodiment one, aiming at the problem that the rotating shaft 52 rotates on the supporting seat 51 and generates large friction and consumes much effort.

[0032] The single-side controlled double-glazed built-in blinds include a frame assembly 1, a plurality of blinds arranged on the frame assembly 1, a pulley slide mechanism 3 arranged on the frame assembly 1, and a fixed iron bar 4 arranged at the output end of the pulley slide mechanism 3. The single-side controlled double-glazed built-in blinds also include a support mechanism 5, a flexible connection mechanism 6, a split installation mechanism 7, an infinite flip mechanism 8 and a tension adjustment mechanism 9; the support mechanism 5 is arranged on the frame assembly 1, and the support mechanism 5 includes a support seat 51 and a rotating shaft 52; the support seat 51 has a pair and is respectively arranged below the frame assembly 1, and the pair of support seats 51 are spaced apart; the rotating shaft 52 is rotatably arranged on the support seat The top of the seat 51 and the middle of the rotating shaft 52 are provided with an opening for the fixing iron bar 4 to pass through, and one side of the rotating shaft 52 is rotatably connected to the frame assembly 1; the flexible connection mechanism 6 is arranged at the output end of the rope pulley slide mechanism 3, and the flexible connection mechanism 6 is used to connect the fixing iron bar 4 with the output end of the rope pulley slide mechanism 3; the split mounting mechanism 7 is arranged on the side of the frame assembly 1; the infinite flip mechanism 8 is arranged on the frame assembly 1, and the infinite flip mechanism 8 is used to connect with the fixing iron bar 4; the tension adjustment mechanism 9 is arranged on the side of the frame assembly 1, and the tension adjustment mechanism 9 is used to adjust the tension of the rope.

[0033] Specifically, the frame assembly 1 is composed of a top plate 11, a bottom plate 12, a right side plate 13 and a guard plate 14. The support seat 51 is connected to the side of the guard plate 14 and the top plate 11 by fasteners. The top plate 11, the bottom plate 12, the right side plate 13 and the guard plate 14 form the frame of the shutter body 2. The guard plate 14 has a pair and is respectively arranged on both sides of the bottom plate 12 and the top plate 11, and the guard plate 14 is used to block the rotating shaft 52 and the support seat 51. This is a prior art and will not be described in detail here. It should be noted that the shape of the fixing iron bar 4 is a U-shaped structure, and the fixing iron bar 4 can be connected to the support mechanism 5 and the infinite flip mechanism 8 respectively. The pulley slide rail mechanism 3 is installed on the frame assembly 1 through a fixing part. The fixing part is a conventional installation component in the field of the shutter body 2 and will not be described in detail here. The pulley slide rail mechanism 3 is an existing driving means in the field of the shutter body 2. Its output end is provided with a rotating handle extending to the outside of the frame assembly 1. This part will not be described in detail. We have improved the structure of the support seat 51. The design of the existing technology in which semicircular notches are provided on both sides of the top of the support seat 51 is optimized to provide a semicircular notch only on one side. After the improvement, when the pulley slide mechanism 3 drives the rotating shaft 52 and the fixed iron bar 4 to rotate, the friction generated by the rotating shaft 52 when rotating at the support seat 51 can be effectively reduced. The spacing between a pair of support seats 51 is preferably 400mm. This distance limit can ensure the stability of the rotating shaft 52 and the fixed iron bar 4 during rotation, avoid the displacement of the fixed iron bar 4 during rotation, and achieve a labor-saving effect. A U-shaped opening is provided on the outside of the rotating shaft 52 for the rope to pass through and be wound around. During use, the rope must first be connected to multiple blinds bodies 2, and then one end of the rope must be wound around the rotating shaft 52 through the U-shaped opening. Finally, a riveting device is used to fix the rope to the rotating shaft 52. This achieves a stable connection between the rope and the blinds body 2 and the rotating shaft 52.

[0034] See Figure 4 and Figure 5 An opening is provided on one side of the top of the support seat 51 for the rotating shaft 52 to pass through and rotate, and the opening is a semicircular structure.

[0035] Specifically, in order to reduce the rotational friction of the rotating shaft 52 on the top of the support base 51, the structure on the other side of the top of the support base 51 is a U-shaped protrusion structure, and the U-shaped protrusion structure does not contact the outer side of the rotating shaft 52. The U-shaped protrusion structure is spaced apart from the outer side of the rotating shaft 52, so it does not affect the rotation of the rotating shaft 52.

[0036] See Figure 6 The flexible connection mechanism 6 includes a first connection part 61; the first connection part 61 is arranged on the frame assembly, and a slot connected to the rope pulley slide mechanism 3 is opened on the side of the first connection part 61, and the first connection part 61 is abutted and connected to the output end of the rope pulley slide mechanism 3 through the slot; and the first connection part 61 is a cylindrical structure.

[0037] Specifically, first connect the slot provided on the side of the first connection portion 61 to the output end of the pulley slide mechanism 3. The first connection portion 61 can be connected to the output end of the pulley slide mechanism 3 through the slot provided on the side.

[0038] See Figure 6 The flexible connection mechanism 6 also includes a second connection part 62; the second connection part 62 is slidably arranged on the side of the rotating shaft 52, and a contact groove directly connected to the rotating shaft 52 and the fixer iron bar 4 is opened on the side of the second connection part 62, and the second connection part 62 is a cylindrical structure, and the outer diameter of the second connection part 62 is larger than the outer diameter of the first connection part 61.

[0039] Specifically, the abutment groove provided on the side of the second connection portion 62 can be connected to the fixer iron bar 4. The abutment groove provided on the side of the second connection portion 62 can achieve rapid docking with the fixer iron bar 4.

[0040] In the actual production process of the second embodiment, the pulley slide mechanism 3 must be manually installed on the frame assembly 1. This operation can easily cause the pulley slide mechanism 3 and the rotating shaft 52 to be misaligned in the same batch of products. When the user uses the pulley slide mechanism 3 to drive the fixing iron bar 4 to rotate, the misalignment and deviation will make the rotation operation extremely laborious.

[0041] See Figure 6 The flexible connection mechanism 6 also includes a first telescopic spring 63; the first telescopic spring 63 is arranged on the first connection part 61, one end of the first telescopic spring 63 is fixed to the first connection part 61, and the other end of the first telescopic spring 63 is fixed to the second connection part 62. The first telescopic spring 63 is located between the first connection part 61 and the second connection part 62. When the distance between the second connection part 62 and the first connection part 61 is extended, the first telescopic spring 63 is in a stretched state.

[0042] Specifically, we have designed a flexible connection mechanism 6. When the workers cause the pulley slide mechanism 3 and the fixed iron bar 4 to be out of center during assembly, the rotational force will be transmitted through the first connecting part 61, the first telescopic spring 63 and the second connecting part 62 during the process of the pulley slide mechanism 3 driving the fixed iron bar 4 to rotate. Since the first connecting part 61 and the second connecting part 62 are connected by the first telescopic spring 63, when the pulley slide mechanism 3 drives the first connecting part 61 to rotate, the rotational force will be transmitted to the second connecting part 62 and the rotating shaft 52 via the first telescopic spring 63, thereby driving the fixed iron bar 4 to rotate. In addition, since the first connecting part 61 and the second connecting part 62 are connected by the first telescopic spring 63, even if the pulley slide mechanism 3 produces position deviation during the installation process of the workers, it will not affect the rotation drive of the rotating shaft 52 and the fixed iron bar 4, and there will be no difficulty in use.

[0043] The third embodiment aims to solve the problems of installation position deviation when the pulley slide rail mechanism 3 is installed inside the second split plate 72 in the prior art and the need to punch holes to inject desiccant after installation.

[0044] See Figure 10 and Figure 11 The split installation mechanism 7 includes a first split plate 71, a second split plate 72 and a sliding cover plate 73; the first split plate 71 is arranged next to the frame assembly 1, and the first split plate 71 is used to install the rope pulley slide rail mechanism 3; the second split plate 72 is slidably arranged on the top of the first split plate 71, and the second split plate 72 can slide and be in abutment with the top of the first split plate 71; the sliding cover plate 73 is slidably arranged on the top of the second split plate 72, and when the sliding cover plate 73 descends, it can be in abutment with the top of the second split plate 72.

[0045] Specifically, in the prior art, the first and second split plates 71 and 72 are integrally formed, with the second split plate 72 being designed as a U-shaped frame. A pair of snap-fitting portions are provided at the top of the first split plate 71 for snapping onto the U-shaped structure of the second split plate 72, thereby completing the installation between the first and second split plates 71 and 72. It is noteworthy that after installation, the U-shaped frame of the second split plate 72 forms a chamber for the pulley rail mechanism 3 to be installed. Therefore, after the conventional first and second split plates 71 and 72 are assembled, workers can then use tools to install the pulley rail mechanism 3 within the second split plate 72. Our improved design features a linear groove at the top of the first split plate 71, which is a T-slot structure and serves to restrict the sliding of the second split plate 72. The second split plate 72 can slide stably along the linear groove at the top of the first split plate 71. It is important to note that the second split plate 72 is L-shaped, enabling quick docking with the first split plate 71. After the worker installs the pulley rail mechanism 3 to the frame assembly 1 through the fixing portion, he presses the sliding cover plate 73 onto the top of the second split plate 72. After the second split plate 72 and the first split plate 71 are slidably installed, abutment grooves are formed on the tops of the first split plate 71 and the second split plate 72 for the sliding cover plate 73 to be pressed and installed. The worker then slides and presses the sliding cover plate 73 onto the second split plate 72. When the installed pulley rail mechanism 3 needs to be inspected, the worker only needs to remove the sliding cover plate 73 from the outside of the second split plate 72 to quickly inspect the pulley rail mechanism 3. This avoids the problem that the traditional integrated first split plate 71 and second split plate 72 are more time-consuming and labor-intensive when installing the pulley rail mechanism 3, and the problem that it is inconvenient to remove the second split plate 72 after installation to inspect the pulley rail mechanism 3. It's worth noting that after the first and second split panels 71, 72, and frame assembly 1 are installed in the prior art, a large corner is formed at the connection between the second split panel 72 and the end face of the frame assembly 1. To ensure the tightness of the connection between the first and second split panels 71, 72, and frame assembly 1, workers use tools to place corner seals between the first and second split panels 71, 72, and frame assembly 1 and then seal them with sealant. However, due to the large angles of the corners, workers use a lot of sealant when performing the sealing operation, which is particularly inconvenient. However, our design of a split mounting mechanism 7 reduces the angle at the installation joint after the first and second split panels 71, 72, and sliding cover 73 are installed and docked with the frame assembly 1. This makes it easier for workers to use fewer corner seals and sealant during subsequent sealing operations. This reduces production costs, makes it easier for workers to apply sealant, and prevents deformation after application.

[0046] In the fourth embodiment, the present invention further provides an infinite flip mechanism 8 for driving the shutter body 2 to rotate.

[0047] See Figure 7-Figure 9 The infinite flip mechanism 8 includes a fixed seat 81 and an abutting rotating shaft 82; the fixed seat 81 has a pair and is respectively arranged on the frame assembly 1, and the top of the fixed seat 81 is provided with an opening for the rotating shaft 52 to pass through and rotate; the abutting rotating shaft 82 is rotatably arranged on the top of the fixed seat 81.

[0048] Specifically, it should be noted that the distance between the pair of fixed seats 81 is preferably 400mm. The pair of openings opened at the top of the fixed seat 81 are both semicircular structures, and the semicircular structures are both used for the rotation of the rotating shaft 52. A circular groove for the wire body to pass through and rotate and wind is opened in the middle of the abutting rotating shaft 82, and the circular groove is used to fix the wire body. When using the fixed seat 81 and the abutting rotating shaft 82, the wire body should be passed through the circular groove and rotated to be wound and knotted on the circular groove, and then the wire body is connected to the shutter body 2. It is worth noting that there is a limiting groove for the fixer iron bar 4 to pass through the middle of the abutting rotating shaft 82. One end of the abutting rotating shaft 82 is connected to the fixer iron bar 4. When the abutting rotating shaft 82 is connected to the fixer iron bar 4 and installed on the fixed seat 81, the rope pulley slide mechanism 3 rotates and drives the abutting rotating shaft 82 into a rotating state through the flexible connection mechanism 6. And it can rotate without restriction, that is, it can rotate infinitely in one direction. Since the friction between the wire and the abutting rotating shaft 82 is small, the abutting rotating shaft 82 can open or close the shutter body 2 through the wire. It should be noted that after the shutter body 2 is closed or opened, even if the user continues to rotate the abutting rotating shaft 82, the shutter body 2 will not continue to rotate and cause damage.

[0049] See Figure 9 The infinite flip mechanism 8 also includes a limiting portion 83; the limiting portion 83 has a pair and is respectively arranged on the outside of the abutting rotating shaft 82, and the pair of limiting portions 83 are both conical structures, which can make the limiting portions 83 rotate synchronously when the abutting rotating shaft 82 rotates.

[0050] Specifically, it is worth noting that the limiting portion 83 is a conical structure, which ensures that when the abutting rotating shaft 82 rotates and drives the wire body to rotate and wind, the wire body will not escape from the outside of the abutting rotating shaft 82. This ensures that the wire body will not have deviation problems caused by displacement during use.

[0051] Embodiment 5 is to solve the problem that the rope becomes slack due to ductility caused by long-term use, making it difficult to drive the slide rail to move, and at the same time avoid the situation where the slide rail slides abnormally and the pulley slide rail mechanism 3 fails to drive due to position deviation when manually assembling the pulley slide rail mechanism 3.

[0052] See Figure 12 and Figure 13 The tensioning adjustment mechanism 9 includes a positioning portion 91, a linear guide rail 92 and a sliding portion 93; the positioning portion 91 is arranged at the bottom of the frame assembly 1; the linear guide rail 92 is arranged beside the positioning portion 91, and the linear guide rail 92 is a cylindrical structure; the sliding portion 93 is slidably arranged on the outside of the linear guide rail 92.

[0053] Specifically, it should be noted that a rope is provided on the outside of the pulley slide mechanism 3, and a slide rail is slidably provided on the top of the second split plate 72, and the two ends of the slide rail are respectively connected to the pulley slide mechanism 3 and the sliding portion 93 through ropes. Then, when the pulley slide mechanism 3 rotates, the slide rail and the sliding portion 93 can be driven by the rope to slide toward or away from the pulley slide mechanism 3.

[0054] See Figure 12 and Figure 13 The tensioning adjustment mechanism 9 also includes a rotating wheel 94 and a second telescopic spring 95; the rotating wheel 94 is rotatably arranged next to the sliding portion 93; the second telescopic spring 95 is arranged on the outside of the linear guide rail 92, one end of the second telescopic spring 95 is fixed to the positioning portion 91, and the other end of the second telescopic spring 95 is fixed to the sliding portion 93. When the sliding portion 93 slides in the direction close to the rope pulley slide rail mechanism 3, the second telescopic spring 95 is in a compressed state.

[0055] Specifically, the rope is wrapped around the outside of the rotating wheel 94 and connected to the upper and lower ends of the slide rail, which then establishes a connection with the pulley slide rail mechanism 3. When the rope is connected to the rotating wheel 94 and the sliding portion 93, it is necessary to ensure that the sliding portion 93 is in the middle of the linear guide rail 92, at which point the second telescopic spring 95 is compressed. This design ensures that the rope remains stretched after installation, ensuring that the pulley slide rail mechanism 3 can continuously stretch the rope through the coordinated action of the sliding portion 93 and the rotating wheel 94, thereby ensuring the stable and normal operation of the rope, slide rail, and the pulley slide rail mechanism 3.

[0056] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
