Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, and particularly relates to a long arm front drag stay with high applicability. Background Art

[0002] During the installation of outward-opening windows, arm front drag stays are necessarily used to connect the two sides of the window and the window frame, so that the window can be limited at any angle during the process of opening outward. However, when the existing arm front drag stays are connected to the window frame, for some special profiles that need to be installed internally, the existing arm front drag stays cannot be directly installed in an embedded manner and need to be fixed after being filled in the embedded groove through structures such as pads, resulting in the disadvantage that there is no available drag stay for internal profiles, which is most common in European standard window frame profiles. When installing the long arm front drag stay, its positioning on the window frame is also rather troublesome, and the connecting rod of the existing arm front drag stay is generally a flat plate structure, and the load-bearing capacity fails to reach the ideal requirement. At the same time, the existing drag stays, whether they are internal middle drags or internal rear drags, have significantly insufficient wind resistance. Summary of the Invention

[0003] In order to solve certain or some technical problems existing in the prior art, the purpose of the present application is to provide a long arm front drag stay with high applicability, which can solve the problem that the existing drag stay needs to be filled with pads when installed on the window frame of internal profiles, and has higher firmness and better stability after installation.

[0004] To solve the above-mentioned existing technical problems, the purpose of the present application is achieved by adopting the following technical solutions:

[0005] A long arm front drag stay with high applicability includes a chute member installed on the window frame, a positioning rod for installing the window sash, and a connecting rod sliding assembly for controlling the unfolding and folding of the positioning rod relative to the chute member. The bottom of the chute member is provided with a downwardly protruding U-shaped chute, and the chute member is installed in the groove of the window frame in an embedded manner through the U-shaped chute.

[0006] Preferably, the chute member includes a T-shaped chute, end plugs and positioning end caps provided at both ends of the T-shaped chute, and the connecting rod sliding assembly slides in the T-shaped chute.

[0007] Preferably, the positioning end cap includes an L-shaped sealing plate and a positioning piece provided at the top of the L-shaped sealing plate and bent outward, and the positioning end cap is positioned by inserting the positioning piece into the groove of the window frame to be installed.

[0008] Preferably, the connecting rod sliding assembly includes a slider main body slidably disposed in the T-shaped chute, a limiting block and a fixing block fixedly installed in the T-shaped chute, a short connecting rod and a middle connecting rod with one end rotatably connected to the slider main body, and a long connecting rod with both ends rotatably connected to the fixing block and the positioning rod respectively. The other end of the middle connecting rod is rotatably connected to the long connecting rod, and one end of the positioning rod is rotatably connected to the end of the short connecting rod.

[0009] Preferably, a protective sleeve is provided at one end of the middle connecting rod away from the slider main body.

[0010] Preferably, the unfolding angle of the positioning rod is 0 to 80°.

[0011] Preferably, the slider main body includes an inner slider slidably connected in the T-shaped chute and an outer slider slidably disposed outside the T-shaped chute, and the inner slider and the outer slider are fixed by a detachable connection structure.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] During the installation of the long support arm front drag sliding brace, the U-shaped chute protruding downward from the bottom of the chute member can be directly embedded into the groove of the window frame. Therefore, during the installation of the chute member and the window frame, for window frames with small grooves on the side such as European standards, there is no longer a need to fill the groove with a spacer block, enabling the built-in profile to also have a sliding brace that can be directly installed for use. The installation is simpler and more convenient, the stability after installation is better, the load-bearing capacity is stronger, it can solve the problem that the existing sliding brace needs to be filled with a spacer block when installed on the window frame of the built-in profile, and at the same time significantly improves its wind resistance during use, achieving a higher load-bearing capacity, making it stronger in load-bearing capacity, simpler in installation method, and better in user experience.

In addition, "and / or" in the description and claims indicates at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0021] As Figure 1 shown, a long arm front drag and slide support with high applicability includes a chute member 4 installed on a window frame, a positioning rod 2 for installing a window sash, and a link sliding assembly 3 for controlling the unfolding and folding of the positioning rod 2 relative to the chute member 4. A downwardly protruding U-shaped chute 1 is provided at the bottom of the chute member 4, and the chute member 4 is embedded in a groove of the window frame through the U-shaped chute 1.

[0022] During the installation process of the long arm front drag and slide support, the downwardly protruding U-shaped chute 1 at the bottom of the chute member 4 can be directly embedded into the groove of the window frame, so that during the installation of the chute member 4 and the window frame, for window frames with small grooves on the side such as European standards, there is no need to fill the groove with a cushion block, and the built-in profile can also be used with a directly installable slide support. The installation is simpler and more convenient, the stability after installation is better, the load-bearing capacity is stronger, and the problem that the existing slide support needs to be filled with a cushion block when installed on the window frame of the built-in profile can be solved. At the same time, the wind pressure resistance during use can be significantly improved. The chute adopts a T-shaped structure, which can not only achieve a high load-bearing capacity but also meet the requirements of the built-in profiles on the market, making it stronger in load-bearing capacity, simpler in installation method, and better in user experience.

[0023] Further improvement is as follows: as Figure 2 shown, the chute member 4 includes a T-shaped chute 42, end plugs 43 provided at both ends of the T-shaped chute 42, and a positioning head 41. The connecting rod sliding assembly 3 is slidably arranged in the T-shaped chute 42.

[0024] After the two ends of the T-shaped chute 42 are blocked by the end plugs 43 and the positioning head 41, it can prevent the connecting rod sliding assembly 3 from falling off during the sliding process, and it is also more convenient for disassembly and assembly. One end of the T-shaped chute 42 is fixed by the positioning head 41. Through the positioning head 41, the side surface of one end of the chute member 4 can be positioned, so that during the installation of the chute member 4, the installation process is more convenient, and the sealing performance of the doors and windows is also greatly improved.

[0025] Even further improvement is that the positioning head 41 includes an L-shaped sealing plate 411 and a positioning piece 412 provided at the top of the L-shaped sealing plate 411 and bent outward. The positioning head 41 is positioned by inserting the positioning piece 412 into the groove of the window frame to be installed.

[0026] Among them, one side of the positioning piece 412 is aligned with one side of the U-shaped chute 1. When the long-arm front drag stay is installed, after the chute member 4 is installed into the groove of the side window frame in an embedded manner through the U-shaped chute 1, only need to insert the positioning piece 412 on the positioning head 41 into the groove on the other side of the window frame again and fit it to one side, so that the side surfaces of the U-shaped chute 1 and the positioning piece 412 that are flush are simultaneously attached to the side surface of the window frame groove, then the quick installation is completed. Thus, after the long-arm front drag stay is installed, it has the effect of positioning on both sides, making it more firm after installation, and the positioning of the long-arm front drag stay is more accurate, and there will be no occurrence of installation tilt or tilt after installation, and the positioning during installation is also simpler and faster.

[0027] Still further improvement is as follows: as Figure 3 shown, the connecting rod sliding assembly 3 includes a slider body 32 slidably arranged in the T-shaped chute 42, a limit block 36 and a fixed block 35 fixedly installed in the T-shaped chute 42, a short connecting rod 31 and a middle connecting rod 33 with one end rotatably connected to the slider body 32, and a long connecting rod 34 with both ends rotatably connected to the fixed block 35 and the positioning rod 2 respectively. The other end of the middle connecting rod 33 is rotatably connected to the long connecting rod 34, and one end of the positioning rod 2 is rotatably connected to the end of the short connecting rod 31.

[0028] A foldable triangular deformation structure is formed among the chute member 4, the middle connecting rod 33 and the long connecting rod 34. A foldable pentagonal structure is formed among the slider body 32, the short connecting rod 31, the middle connecting rod 33, the positioning rod 2 and the long connecting rod 34. When the positioning rod 2 is opened and closed along the window sash, the slider body 32 can slide along the T-shaped chute 42, so that the triangular deformation structure and the pentagonal structure can be deformed and adjusted synchronously. When the window sash is closed, the short connecting rod 31, the middle connecting rod 33, the positioning rod 2 and the long connecting rod 34 can be stacked on the chute member 4, so that the overall volume is smaller and it is more convenient to fold. One end of the middle connecting rod 33 is rotatably connected to the middle position of the positioning rod 2, which can make the supporting effect of the positioning rod 2 better when it is unfolded and the stability is better after unfolding. Combined with the grafting of the short connecting rod 31, the opening angle of the window sash can be larger and the length of the installable long connecting rod 34 can be larger. The limit block 36 is installed in the U-shaped chute 1 by rivets or pin shafts. When the slider body 32 slides, the sliding limit position can be controlled by the limit block 36, so as to control the maximum unfolding angle of the positioning rod 2.

[0029] Further improved, a protective sleeve 5 is provided at one end of the middle connecting rod 33 away from the slider body 32; the unfolding angle of the positioning rod 2 is 0-80°.

[0030] A metal protective sleeve 5 is installed at one end of the middle connecting rod 33 away from the slider body 32. At the same time, the short connecting rod 31 is thickened, and the thickness of the short connecting rod 31 is greater than the sum of the thicknesses of the middle connecting rod 33 and the long connecting rod 34, so that its load-bearing capacity is stronger. After the window sash is installed through the connecting rod sliding assembly 3, the window sash can be opened, closed and positioned arbitrarily at an angle of 0-80°, and its maximum opening angle can be adjusted by the limit block 36, so as to meet different building requirements.

[0031] Further improved, the slider body 32 includes an inner slider 322 slidably connected in the T-shaped chute 42 and an outer slider 321 slidably arranged outside the T-shaped chute 42, and the inner slider 322 and the outer slider 321 are fixed by a detachable connection structure.

[0032] The inner slider 322 slides along the inner groove of the T-shaped chute 42, while the outer slider 321 is fixed on the inner slider 322 by rivets or the like and is installed in a U-shape on the outer side of the upper end of the T-shaped chute 42 and slides along the outer contour of the T-shaped chute 42, so that during the sliding process of the slider body 32, the garbage in the inner and outer areas of the T-shaped chute 42 can be quickly cleaned, avoiding the phenomenon of jamming during the sliding process of the slider body 32.

[0033] The above embodiments are only the preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantive changes and substitutions made by those skilled in the art based on the present application fall within the scope of protection required by the present application.
