Description

Technical Field

[0001] The utility model relates to the technical field of sliding mechanisms, and particularly to a translation and track-changing assembly. Background Art

[0002] In modern industrial manufacturing and household life, slide rail structures are widely used in various equipment and devices, such as mechanical equipment, doors and windows, etc. The slide rail structure enables the equipment and objects to smoothly move on the track, so as to achieve the expected effect.

[0003] The pulley usually slides along a predetermined straight path. When the pulley needs to change the track or turn, the pulley must leave the original straight slide rail at the turning point and turn to the new slide rail direction. For this purpose, it may be necessary to additionally set a turning track at the track corner. In the traditional slide rail design, when the pulley enters the track-changing track, it is easy to contact the side wall of the track. This contact will cause the pulley to have unstable states such as jamming, shaking or deviating from the track when turning, thus affecting the normal operation of the equipment, reducing the use experience, and may cause wear of the equipment, increasing the possibility of maintenance and replacement.

Detailed implementation manners

[0042] The general idea of the technical solution provided by the present utility model is as follows:

[0043] Please refer to Figures 1 to 17 , the translation and orbit-changing assembly includes: a support assembly 100, on which a load-bearing pulley 110 and a guiding pulley 120 are provided. The load-bearing pulley 110 is vertically arranged, and the guiding pulley 120 is horizontally arranged. The support assembly 100 is used to connect with the object to be carried;

[0044] An arc-shaped guide rail 200, on both sides inside the arc-shaped guide rail 200, there are convex platforms 210. The load-bearing pulley 110 is used for sliding connection with the convex platforms 210. Inside the arc-shaped guide rail 200, there is an accommodating portion 220 for accommodating the guiding pulley 120;

[0045] Wherein, the distance from the guiding pulley 120 to the side wall of the accommodating portion 220 is less than the distance from the load-bearing pulley 110 to the side wall of the arc-shaped guide rail 200.

[0046] Specifically, the load-bearing pulley 110 is vertically arranged on the bracket assembly 100 and is used to slide on the boss 210 within the arc-shaped guide rail 200 to carry the bracket assembly 100; the guiding pulley 120 is horizontally arranged on the bracket assembly 100 and is used to slide within the accommodating portion 220 and guide the movement direction of the entire bracket assembly; the bosses 210 are arranged on both sides of the arc-shaped guide rail 200 and are used to carry the sliding load-bearing pulley 110; the accommodating portion 220 is arranged inside the arc-shaped guide rail 200 and is used to accommodate the sliding guiding pulley 120. The distance from the guiding pulley 120 to the side wall of the accommodating portion 220 is less than the distance from the load-bearing pulley 110 to the side wall of the arc-shaped guide rail 200. Such a design enables the guiding pulley 120 to come into contact with the inner wall of the arc-shaped guide rail 200 first when the bracket assembly 100 undergoes translation, thereby optimizing the steering angle, preventing the load-bearing pulley 110 from contacting the side wall of the arc-shaped guide rail 200, achieving smooth steering, further improving the operation stability, and extending the service life of the device.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the scope of protection of the present utility model.

[0048] Please refer to Figures 9 to 10 and Figures 13 to 17 , the bracket assembly 100 includes: a first bracket assembly 300 and a second bracket assembly 400. The first bracket assembly 300 is provided with a first load-bearing pulley 310 and a first guiding pulley 320, and the edge of the side portion of the first guiding pulley 320 extends beyond the edge of the side portion of the first load-bearing pulley 310; the second bracket assembly 400 is provided with a second load-bearing pulley 410 and a second guiding pulley 420, and the edge of the side portion of the second load-bearing pulley 410 extends beyond the edge of the side portion of the second guiding pulley 420. The first guiding pulley 320 and the second guiding pulley 420 are arranged vertically and staggered.

[0049] The arc-shaped guide rail 200 includes a first arc-shaped guide rail 500 and a second arc-shaped guide rail 600 respectively used for cooperating with the first bracket assembly 300 and the second bracket assembly 400. The first arc-shaped guide rail 500 is provided with a first accommodating portion 510 for accommodating the first guiding pulley 320, and the second arc-shaped guide rail 600 is provided with a second accommodating portion 610 for accommodating the second guiding pulley 420.

[0050] Specifically, the bracket assembly provided by the present application includes two independent brackets, namely the first bracket assembly 300 and the second bracket assembly 400, which can be respectively connected to the same horizontal plane of the object to be carried, thereby forming a more stable support structure.

[0051] A first load-bearing pulley 310 and a first guiding pulley 320 are installed on the first bracket assembly 300. The edge of the side of the first guiding pulley 320 extends beyond the edge of the side of the first load-bearing pulley 310, which can more effectively guide the object to be carried to move along a predetermined turning trajectory. Moreover, it is also beneficial for the first guiding pulley 320 to bear a greater lateral sliding friction force during turning.

[0052] A second load-bearing pulley 410 and a second guiding pulley 420 are installed on the second bracket assembly 400. Among them, the edge of the side of the second load-bearing pulley 410 extends beyond the edge of the side of the second guiding pulley 420. During load-bearing, the load-bearing pulley needs to bear most of the weight of the object to be carried. And the edge of the second load-bearing pulley 410 extends beyond the edge of the second guiding pulley 420, which can make the gravity of the object to be carried more evenly distributed on the second load-bearing pulley 410, avoiding the instability of the pulley caused by the offset of the gravity center.

[0053] The first guiding pulley 320 and the second guiding pulley 420 are arranged in a vertically staggered manner. For example, please refer to Figure 9 , the first guiding pulley 320 is arranged above the first load-bearing pulley 310. Please refer to Figure 10 , and the second guiding pulley 420 is arranged below the second load-bearing pulley 410. By arranging the first guiding pulley 320 and the second guiding pulley 420 in a vertically staggered manner like this, the two guiding pulleys can always be kept inside the arc-shaped guide rail during the sliding process and slide on the upper and lower parts of the arc-shaped guide rail respectively. This design optimizes the turning and load-bearing effects of the pulleys, is beneficial to providing a more balanced support and guiding force during the sliding process, enables the forces applied to the pulleys to be more balanced when the object to be carried moves horizontally or vertically, and thus realizes a more stable and smooth movement effect.

[0054] The utility model further includes two independent arc-shaped guide rails, namely the first arc-shaped guide rail 500 and the second arc-shaped guide rail 600 that are respectively matched with the first bracket assembly 300 and the second bracket assembly 400. A first accommodating portion 510 is provided inside the first arc-shaped guide rail 500 for accommodating the sliding of the first guiding pulley 320. A second accommodating portion 610 is provided inside the second arc-shaped guide rail 600 for accommodating the sliding of the second guiding pulley 420.

[0055] Please refer to Figure 9 and Figure 10, the space between the two bosses 210 inside the arc-shaped guide rail 200 forms the second accommodation part 610, and the space above the boss 210 forms the first accommodation part 510. That is, the first accommodation part 510 and the second accommodation part 610 can be arranged within the same arc-shaped track 200. The first arc-shaped guide rail 500 and the second arc-shaped guide rail 600 can have the same structure. In other words, with only one arc-shaped guide rail 200 in this design, both the first accommodation part 510 and the second accommodation part 610 can be formed simultaneously. This design not only saves materials but also reduces the processing difficulty. More importantly, since the first arc-shaped guide rail 500 and the second arc-shaped guide rail 600 have the same structure, during the production process, there is no need to open additional molds, which undoubtedly saves a large amount of mold-opening costs for the manufacturer and improves production efficiency. At the same time, this design can also reduce the difficulty of later maintenance and replacement and reduce the maintenance cost.

[0056] Please refer to Figure 13 and Figure 14 , the translation and track-changing assembly further includes a linear guide rail 700. One end of the linear guide rail 700 is connected to one end of the first arc-shaped guide rail 500, and an opening 710 is provided on the side of the linear guide rail 700 and is connected to one end of the second arc-shaped guide rail 600. For example, the first support assembly 300 and the second support assembly 400 are connected to both sides of a load-bearing object. At the beginning, the first support assembly 300 and the second support assembly 400 are on the linear guide rail 700 and they move in a linear manner. Then, please refer to Figure 17 , when the first support assembly 300 moves to the position of the first arc-shaped guide rail 500, since the edge of the first guide pulley 320 exceeds the edge of the side of the first load-bearing pulley 310, the first guide pulley 320 will contact the side wall of the first accommodation part 510 of the first arc-shaped guide rail 500, thereby guiding the first support assembly 300 into the first arc-shaped guide rail 500 for turning. At the same time, please refer to Figure 16 , as the first support assembly 300 moves, the second support assembly 400 moves along. When the first support assembly 300 turns, the second support assembly 400 also turns accordingly, so that the second guide pulley 420 enters the corresponding second accommodation part 610 inside the second arc-shaped guide rail 600. Therefore, through this design, the first support assembly 300 and the second support assembly 400 synchronously complete the turning from the linear guide rail 700 to the first arc-shaped guide rail 500 and the second arc-shaped guide rail 600. Conversely, when it is necessary to turn from the arc-shaped track 200 to the linear guide rail 700, it should also be through the interaction of the first guide pulley 320 and the second guide pulley 420 with their respective arc-shaped tracks to guide the first support assembly 300 and the second support assembly 400 back to the linear guide rail 700 respectively.

[0057] Please refer to Figures 13 to 17 , the translation and track-changing assembly further includes:

[0058] A window and door frame 810, a linear guide rail 700, a first arc guide rail 500 and a second arc guide rail 600 are all connected to the window and door frame 810;

[0059] A first window and door sash 820 is fixed within the window and door frame 810;

[0060] A second window and door sash 830, a first support assembly 300 and a second support assembly 400 are connected to the second window and door sash 830. The first support assembly 300 and the second support assembly 400 are used to carry the second window and door sash 830 to slide on the linear guide rail 700, the first arc guide rail 500 and the second arc guide rail 600; The second window and door sash 830 is carried by the first support assembly 300 and the second support assembly 400 and slides on the linear guide rail 700, the first arc guide rail 500 and the second arc guide rail 600. This design enables the second window and door sash 830 to move flexibly along each guide rail, thereby achieving the effect of opening and closing the window and door. Specifically, please refer to Figure 13 , when the window and door are in the closed state, the first window and door sash 820 and the second window and door sash 830 are in the same plane, and the first support assembly 300 and the second support assembly 400 are located at one end of the arc guide rail 200 away from the linear guide rail 700. When the window and door need to be opened, please refer to Figure 14 , the user pushes the second window and door sash 830 so that the first support assembly 300 and the second support assembly 400 move from the arc guide rail 200 to the linear guide rail 700, and translates and pushes the second window and door sash 830 on the linear guide rail 700 to open the window. When the window needs to be closed, translate and push the second window and door sash 830, please refer to Figure 17 , when the first support assembly 300 moves to the position of the first arc guide rail 500, since the edge of the first guide pulley 320 exceeds the side edge of the first load-bearing pulley 310, the first guide pulley 320 will contact the side wall of the first receiving portion 510 of the first arc guide rail 500, thereby guiding the first support assembly 300 into the first arc guide rail 500 for turning. At the same time, please refer to Figure 16 , as the first support assembly 300 moves, the second support assembly 400 moves along. When the first support assembly 300 turns, the second support assembly 400 also turns accordingly, so that the second guide pulley 420 enters the corresponding second receiving portion 610 in the second arc guide rail 600. At this time, push the second window and door sash 830 to move it to a position horizontal with the first window and door sash 820, thereby completing the closing of the window and door.

[0061] It can be understood that the linear guide rail 700, the first arc guide rail 500, and the second arc guide rail 600 can be connected to the bottom of the door and window frame 810, or can be connected to the top of the door and window frame 810. Similarly, the first support assembly 300 and the second support assembly 400 can be connected to the bottom of the second door and window sash 830, or can be connected to the top of the second door and window sash 830, and can be adjusted according to the actual requirements and installation conditions of the doors and windows.

[0062] Please refer to Figure 2 and Figure 11 , the support assembly 100 includes: a fixed support 130 and a pulley support 140. The pulley support 140 is rotatably connected to the fixed support 130. The pulley support 140 is provided with a load-bearing pulley 110 and a guiding pulley 120. Specifically, the pulley support 140 and the fixed support 130 adopt a rotatable connection method, so that the pulley support 140 can rotate when needed. For example, when the support assembly 100 enters the curved position of the arc guide rail 200, the guiding pulley 120 contacts the side wall of the guide rail and conducts guiding. The pulley support 140 can rotate under the guiding action of the guiding pulley 120. By utilizing the rotation function of the pulley support 140, greater flexibility is provided, enabling the pulley support 140 to rotate and flexibly pass through the curved position of the arc guide rail 200, making the overall movement of the support assembly 100 smoother.

[0063] Please refer to Figure 3 and Figure 12 , the pulley support 140 includes a first pulley support 141 and a second pulley support 142. Both the first pulley support 141 and the second pulley support 142 are rotatably connected to the fixed support 130. Both the first pulley support 141 and the second pulley support 142 are provided with a load-bearing pulley 110 and a guiding pulley 120. By having both the first pulley support 141 and the second pulley support 142 rotatably connected to the fixed support 130, the flexibility and adaptability of the support assembly 100 are further improved.

[0064] It can be understood that the above-mentioned rotatable connection methods can include existing rotatable connection methods such as hinge connection, sliding bearing connection, or spherical bearing connection, etc.

[0065] Please refer to Figure 3 and Figures 5 to 8, the fixed bracket 130 includes a fan material fixed bracket 131 and a fixed rod 132. The fan material fixed bracket 131 is provided with a through connection channel 1311. The fixed rod 132 is connected within the connection channel 1311. The fan material fixed bracket 131 is used for fixedly connecting with the door and window fan. The first end of the fixed rod 132 is rotatably connected to the pulley bracket 140. The second end of the fixed rod 132 is used for connecting with the fan material fixed bracket 131. The first end and the second end of the fixed rod 132 are the opposite ends of the fixed rod 132. Specifically, the fan material fixed bracket 131 can fix the pulley bracket 140 on the fan material, and the fixed rod 132 is the bridge connecting the pulley bracket 140 and the fan material fixed bracket 131. The fan material fixed bracket 131 can be fixedly connected with the fan material by means of bolts. For example, the fan material fixed bracket 131 is provided with perforations for receiving bolts, and then the fan material fixed bracket 131 and the fan material are connected by bolts. The through connection channel 1311 can limit and assemble the fixed rod 132.

[0066] Please refer to Figure 6 , a screw member 1312 is threadedly connected to the first end of the connection channel 1311. The fixed rod 132 enters the connection channel 1311 from the second end of the connection channel 1311 and is abutted by the screw member 1312. The first end and the second end of the connection channel 1311 are the opposite ends of the connection channel 1311. Specifically, the fan material fixed bracket 131 can be arranged at the bottom of the door and window fan and is used for supporting the door and window fan. The design of the screw member 1312 not only provides stable connection support for the fixed rod 132, but also realizes accurate adjustment of the position of the fixed rod 132 relative to the connection channel 1311. Specifically, by using the thread design between the screw member 1312 and the connection channel 1311, by rotating the screw member 1312, the depth of the screw member 1312 within the connection channel 1311 can be changed. And the fixed rod 132 is abutted by the screw member 1312. When the screw member 1312 rotates in or out, the fixed rod 132 will move up or down accordingly, thereby completing the adjustment of the position of the fixed rod 132 within the connection channel 1311. By adjusting the position of the fixed rod 132 within the connection channel 1311, the relative distance between the fan material fixed bracket 131 and the pulley bracket 140 can be realized, so as to adjust the height of the door and window fan. Through the above designs, when it is necessary to change the position of the fixed rod 132, only need to manually or use a tool to rotate the screw member 1312, which is simple and fast.

[0067] Please refer to Figure 5 , Figure 7 and Figure 8, the second end of the fixing rod 132 is provided with a threaded portion 1321. A spring member 1313 is also provided in the connection channel 1311. The second end of the fixing rod 132 passes through the spring member 1313 and then passes through the connection channel 1311 and is threadedly connected to the screw connector 900. Specifically, in this design, the fan material fixing bracket 131 can be arranged at the top of the door and window fan and used to lift the door and window fan. The threaded connection between the threaded portion 1321 and the screw connector 900 can connect the second end of the fixing rod 132 to the fan material fixing bracket 131, and the spring member 1313 is usually used to provide a stable elastic force. When the fan material fixing bracket 131 lifts the door and window fan, the fan material fixing bracket 131 is subjected to a downward force, thereby compressing the spring member 1313. More specifically, the side wall of the connection channel 1311 of the fan material fixing bracket 131 can be provided with a convex portion 1314. When the fan material fixing bracket 131 is pressed down, the convex portion 1314 abuts against the spring member 1313 and presses it down.
