Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a pulley device and a door and window. Background Art

[0002] In the hardware system of sliding doors and windows, it is usually necessary to realize the push-pull opening and closing in the form of a pulley block, and the pulley blocks in the prior art usually use an integrated pulley block or a split pulley block. For sliding doors and windows of different weights, the methods of adding and reducing pulleys in the integrated pulley block and the split pulley block are different. For the integrated pulley block, multiple integrated pulley blocks are often added or replaced with an integrated pulley block with fewer pulleys. When multiple integrated pulleys are added, it is easy to make pulley blocks of various specifications in the same sliding door and window. It takes up more manpower and site resources, and when any wheel in the integrated pulley block is damaged, the entire pulley block needs to be replaced, and the maintenance cost of replacement is high. As for the split pulley block, the number of pulleys is often reduced by adding multiple sets of split pulley blocks or disassembling the split pulley blocks. However, when adding multiple sets of split pulley blocks, it is necessary to punch holes in doors and windows, and then fix the pulley blocks with screws, etc. When reducing the split pulley blocks, it is necessary to remove the screws to remove the pulley blocks. This installation and disassembly method is inconvenient. Utility Model Content

[0035] See also Figure 1-Figure 3 An embodiment of the utility model provides a pulley device, which is applied to doors and windows. The doors and windows include a frame profile 1 and a sash profile 2. The pulley device is arranged between the frame profile 1 and the sash profile 2. The pulley device includes a pulley body 5 and at least one pulley group 3. The pulley body 5 is fixedly arranged in the frame profile 1 or one of the sash profiles 2. The pulley group 3 includes at least one pulley 31 and a support member 32. The support member 32 is detachably arranged on the pulley body 5, and the pulley 31 is limited on the support member 32.

[0036] In this embodiment, the pulley device is arranged between the frame profile 1 and the fan profile 2, so as to realize the pushing, pulling, opening and closing actions of the doors and windows, wherein the pulley device includes a pulley block 3 and a pulley body 5, the pulley body 5 is fixedly arranged in the frame profile 1 or one of the fan profiles 2, and the pulley body 5 is used as a pulley block bracket, and the pulley block 3 is installed in the pulley body 5. The specific installation method is: the support member 32 is arranged on both sides of the pulley 31 and combined and connected to form the pulley block 3, and the support member 32 is detachably arranged in the pulley body 5, thereby limiting the pulley 31, so that one side of the pulley 31 protrudes out of the pulley body 5, so that the pulley 31 can slide stably between the frame profile 1 and the fan profile 2.

[0037] Specifically, Figure 4-5 As shown, a track 11 is provided on a side of the frame profile 1 and / or the fan profile 2 that contacts the pulley 31 , and the pulley 31 is rollingly connected to the track 11 .

[0038] In this embodiment, a track 11 is provided on a side of the frame profile 1 and / or the sash profile 2 that contacts the pulley 31, thereby reducing the contact area between the pulley 31 and the frame profile 1 or the sash profile 2, thereby reducing friction and resistance when the pulley 31 rolls on the track 11, thereby improving the push-pull efficiency. Through the combination of the pulley 31 and the track 11, the user can easily push or pull the door or window without excessive force, and through the support of the track 11, the stability and load-bearing capacity of the pulley are increased, so that it can follow the direction of the track 11 during rolling and is not easy to tilt or shake.

[0039] Specifically, Figure 4-5 As shown, the outer periphery of the pulley 31 is a concave arc surface, the track 11 is convexly arranged, and the concave arc surface of the pulley 31 contacts the track 11; or, the outer periphery of the pulley 31 is a convex arc surface, the track 11 is concavely arranged, and the convex arc surface of the pulley 31 contacts the track 11.

[0040] In this embodiment, by setting the pulley 31 and the track 11 as matching concave-convex structures, the pulley 31 can slide stably on the track 11. Moreover, the design of the convex-concave structure can better fix the pulley 31 on the track 11, reducing the noise and vibration generated during the sliding process.

[0041] Specifically, Figure 1-Figure 2 As shown, a plug assembly 4 is also included, and the plug assembly 4 is detachably arranged at both ends of the pulley body 5.

[0042] In this embodiment, the plug assembly 4 is used to limit the pulley block 3 so that the pulley block 3 cannot slide out of the pulley body 5, and the plug assembly 4 at at least one end is detachable, which is convenient for installation and removal of the pulley block 3. The pulley block 3 can be slid into the pulley body 5 for installation or slid out of the pulley body 5 for removal by simply taking out the plug assembly 4. In a specific example, the plug assembly 4 can also be slid into the pulley body 5 and slid to both ends of the pulley block 3 to limit the pulley block 3.

[0043] Specifically, Figure 2 and Figure 6 As shown, there are multiple pulley blocks 3, which are arranged side by side and / or in parallel.

[0044] In this embodiment, in order to adapt to sliding doors and windows of different weights, the pulley groups 3 can be set with a corresponding number of pulley groups 3 according to the weight adapted to the sliding doors and windows, and multiple pulley groups 3 can be arranged side by side and / or in parallel between the frame profile 1 and the fan profile 2, thereby improving the load-bearing capacity.

[0045] Specifically, one of the frame profile 1 and the fan profile 2 is provided with an installation groove 21 with an opening on one side, the pulley body 5 is installed in the installation groove 21, the pulley body 5 is provided with a receiving groove 51 along the length direction, and the support member 32 is slidably inserted into the receiving groove 51.

[0046] In this embodiment, one of the frame profile 1 and the fan profile 2 is provided with a mounting groove 21 for mounting the pulley body 5, and the pulley body 5 is provided with a receiving groove 51 along the length direction, and the support member 32 is slidably inserted in the receiving groove 51, so that the pulley block 3 is installed in the receiving groove 51, and the other of the frame profile 1 and the fan profile 2 is provided with a track 11 for rolling connection with the pulley 31, such as Figure 1 As shown, the mounting groove 21 is provided in the fan profile 2, the pulley body 5 is installed in the mounting groove 21, and the side of the frame profile 1 that contacts the pulley block 3 is provided with a track 11; the mounting groove 21 is provided in the frame profile 1, and the pulley body 5 can be installed in the mounting groove 21, or the pulley block 3 can be directly installed in the mounting groove 21 (as shown in FIG. Figure 7-9 As shown), a track 11 is arranged on the side where the fan profile 2 contacts the pulley block 3. Both of the above-mentioned two arrangements enable the pulley block 3 to realize the push-pull action of the doors and windows.

[0047] In a specific embodiment, the number of suitable pulleys 31 can be increased according to the load-bearing requirements of the doors and windows, and the pulley block 3 is slid into the pulley body 5, and the pulley block 3 is limited by the plug assembly 4, so that the pulley block 3 cannot slide out of the receiving groove 51. If the receiving groove 51 in the pulley body 5 is relatively large, according to the load-bearing requirements of the doors and windows, only one set of pulley blocks 3 is needed to bear the load. At this time, after the pulley block 3 is slid into the receiving groove 51, the plug assembly 4 also slides into the receiving groove 51 and slides into the end position of the pulley block 3, thereby limiting the pulley block 3.

[0048] Specifically, Figure 6 As shown, the accommodating grooves 51 are provided in multiple rows and / or columns for mounting multiple pulley blocks 3 .

[0049] In this embodiment, the number of appropriate pulleys 31 is increased according to the load-bearing requirements of the doors and windows, and multiple pulleys 31 are assembled into a structure of multiple pulley blocks 3. The receiving grooves 51 are set to a multi-row structure and / or a multi-column structure according to the number of pulley blocks 3, so that all pulley blocks 3 can completely slide into the receiving grooves 51, and then the corresponding number of plug assemblies 4 are installed at both ends of the receiving grooves 51 according to the number and structure of the receiving grooves 51. It should be noted that Figure 7 There is no accommodating groove 51, so the mounting groove 21 of the frame profile 1 can be set to a structure of multiple rows and / or multiple columns, so as to install multiple groups of pulley blocks 3.

[0050] Specifically, Figure 2 , Figure 3 and Figure 6As shown, the two side walls of the accommodating groove 51 are provided with limiting grooves 52 , and the supporting member 32 is provided with a protrusion 322 matching therewith, and the protrusion 322 cooperates with the limiting grooves 52 to limit the movement of the supporting member 32 in a direction perpendicular to the rolling direction of the pulley 31 .

[0051] In this embodiment, the limiting groove 52 is a dovetail structure, distributed on both sides of the receiving groove 51, and the support member 32 is provided with a protrusion 322 matching the dovetail structure. The protrusion 322 cooperates with the limiting groove 52, so that the installation of the pulley block 3 is more stable, and the limiting groove 52 limits the moving direction of the support member 32, so that the support member 32 cannot move toward the two sides of the groove (that is, it cannot move in a direction perpendicular to the rolling direction of the pulley 31), thereby reducing the deformation or damage of the receiving groove 51. Figure 7 As shown, the retaining grooves 22 are arranged on the groove walls on both sides of the installation groove 21 of the frame profile 1. The retaining grooves 22 are also dovetail structures. The retaining grooves 22 have the same function as the limiting grooves 52.

[0052] Specifically, the support member 32 is separately provided, and a support hole 321 matching the pulley 31 is provided on the support member 32, and the pulley 31 and the support members 32 on both sides are spliced ​​to form the pulley assembly 3; or, the support member is integrally formed and a accommodating space is formed, and support holes matching the pulley are provided on both sides of the accommodating space.

[0053] In this embodiment, the support member 32 includes two structural settings. The first type is a split setting, such as Figure 3 As shown, the split support members 32 are spaced apart on both sides of the pulley 31, and the pulley 31 and the support member 32 are detachably connected. A support hole 321 is provided on the support member 32, and a pulley shaft 311 is provided on the pulley 31. The pulley shaft 311 is rotatably connected in the support hole 321, thereby splicing to form the pulley block 3; the second type is an integrated molding setting, in which an accommodating space is provided in the integrated support member 32. The pulley 31 is placed in the accommodating space and the pulley 31 is installed according to the position of the support hole 321, thereby forming the pulley block 3.

[0054] If one of the pulleys in the pulley block 3 is damaged, for the first type of support member 32, the support members 32 on both sides are separated to separate the pulley shaft 311 from the support hole 321, thereby realizing the disassembly of the pulley block 3, and then the damaged pulley 31 can be replaced; for the second type of support member 32, the damaged pulley 31 can be directly removed from the support member 32 and then replaced.

[0055] In addition, the number of pulleys 31 can be increased at will in this embodiment to increase the load-bearing capacity. The pulleys 31 can be increased by assembling multiple pulley blocks 3, such as two pulleys 31 and two side supports 32 as a pulley block 3, assembling a corresponding number of pulley blocks 3, and then installing the multiple pulley blocks 3 in the frame profile 1 and the fan profile 2. Alternatively, the pulleys 31 can be increased by adding more pulleys to a group of pulley blocks 3, such as replacing the support member 32 with a support member 32 of a suitable length, and then opening a corresponding number of support holes 321 according to the number of pulleys, and then installing multiple pulleys 3 on the support member 32. The arrangement of multiple pulley blocks 3 and extended support members 32 can make the pulley device adapt to sliding doors and windows of different weights. Moreover, in multiple pulley blocks 3, if a pulley 31 is damaged, the corresponding pulley block 3 can be disassembled and the damaged pulley 31 can be replaced. In one pulley block 3, if one of the pulleys 31 is damaged, the support members 32 on both sides can be separated or the damaged pulley 31 can be directly disassembled to separate the pulley shaft 311 from the support hole 321, thereby realizing the disassembly and replacement of the specified pulley 31 and reducing the maintenance cost.

[0056] Specifically, the support member 32 is made of non-metallic material or metal-coated plastic material.

[0057] In this embodiment, the support member 32 is in non-rigid contact with the pulley shaft 311 of the pulley 31, so the material of the support member 32 can be preferably a non-metallic material or a metal-coated plastic material. During the sliding process of the entire pulley device, the vibration of the pulley 3 is absorbed by the support member 32, thereby achieving a silent effect. Among them, the non-metallic material includes a plastic material and an elastic material.

[0058] like Figure 1 and Fig. 9 , and combined with Figure 4-Figure 5 As shown, the embodiment of the utility model also provides a door and window, including a frame profile 1, a sash profile 2 and the pulley device as described above, wherein the pulley device is arranged between the frame profile 1 and the sash profile 2 to facilitate the push-pull opening and closing action of the door and window.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
