Description

Technical Field

[0001] The utility model belongs to the technical field of building door and window accessories, and specifically relates to a stepless limiting magnetic damping wind brace. Background Art

[0002] Wind bracing is installed at the upper and lower ends of the external casement window. There is also a type of wind bracing that is installed at both ends of the top-hung window. The wind bracing is installed at the top-hung window to play a supporting role. Because the top-hung window will close when it is opened and the wind blows, it must be supported by wind bracing. The wind bracing can open and close the window and support the window sash, so that the window sash can be opened to a certain angle as needed, and the window sash can be limited to swing at will due to wind pressure, which plays a role of fixing, stabilizing or limiting. At present, there are two types of wind bracing, one for casement windows, also known as four-link in the industry, which plays a load-bearing and limit role; the other is for hanging windows, which plays a load-bearing role. The wind bracing plays the role of a cantilever for the weight of the window sash. When it is opened outward, it must also withstand wind load damage. The hardware components have high quality requirements and play a limit role when it is opened inward. The most common wind bracing on the market now is a side rod structure, which has a complex structure and cannot limit the limit steplessly. It can only limit at a few fixed points. In response to this problem, we urgently need to develop a wind bracing with a simple structure that can achieve stepless limit, that is, it can be limited at any position. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0022] Combination Figure 1-4 As shown, the present application discloses a stepless limit magnetic damping wind brace, including a base 1, a rocker arm 3 and an upper cover 4, the base 1 is fixed on a window body 9, specifically, the window body 9 has an outer frame 91 and an inner frame 92, the height of the inner frame 92 is lower than the height of the outer frame 91, and a slot 93 is provided on the upper end surface of the inner frame 92, the base 1 has a screw mounting hole 13, and the self-tapping screw 8 is tightened on the inner frame 92 after passing through the screw mounting hole 13; in order to better position the base 1, it is preferred that the base 1 extends downward with a stop portion 14, the stop portion 14 is inserted into the slot 93 of the window body, and is inserted into the slot 93 through the stop portion 14, so as to facilitate rapid positioning of the base, and during the use of the wind brace, part of the force borne by the screw 8 can be shared, thereby improving the connection reliability between the base and the window. The swing rod 3 is located between the base 1 and the upper cover 4. Ears are extended on both sides of the upper cover 4. Screw holes 41 are opened on the ears. Screws 7 pass through the screw holes 41 and are screwed into the threaded holes 13 of the base 1 to connect the upper cover 4 to the base 1. A rotating shaft 11 is arranged in the middle of the base 1. An axial hole 321 is arranged at the connecting end of the swing rod 3 and the base 1. The swing rod 3 is sleeved on the rotating shaft 11 with the aid of the axial hole 321, so that one end of the swing rod 3 can be rotatably arranged on the base 1. The end of the swing rod 3 away from the base 1 is processed with a mounting boss 33 in a stamping manner. A plastic sleeve 6 is sleeved on the mounting boss 33. The plastic sleeve 6 is preferably made of nylon, wherein, Figure 3 As shown, after installation, the plastic sleeve 6 is partially inserted into the slide groove 101 at the bottom of the window sash 10 to realize the movable connection between the swing rod and the window sash 10, and the self-lubricating property of nylon can also ensure that the plastic sleeve 6 slides flexibly in the slide groove 101 and minimizes the wear on the window sash.

[0023] Furthermore, in this embodiment, considering the stepless adjustment of the position of the swing rod 3, a magnet 5 is provided at the connection end of the swing rod 3 and the base 1, and at least the upper cover 4 is made of magnetic material. The upper cover 4 maintains contact with the swing rod 3 under the action of magnetic force. Specifically, Figure 1-2 As shown, the connecting end of the swing rod 3 and the base 1 is circular, and a plurality of magnet mounting holes 322 are evenly distributed along the radial direction thereof, and the magnet 5 is fixed in the magnet mounting hole 322. By arranging a magnet on the swing rod, and the magnet is magnetically attracted to the magnetic upper cover, so as to maintain contact, then under the action of the magnetic force, at least the upper cover and the swing rod can maintain contact friction, thereby providing the damping force required for the swing rod to rotate, and then the magnetic force of the magnet is adaptively selected, so that the swing rod can be stopped at any position, thereby realizing stepless adjustment of the opening of the window sash. Further, considering that the upper limit of the friction force of the contact friction between the upper cover 4 and the swing rod 3 may be difficult to stably and reliably maintain the friction force required for the swing rod, thereby causing the wind brace to be unstable in positioning, for this reason, it is further preferred that a damping material is arranged at least between the upper cover 4 and the swing rod 3, for example, the damping material is compounded on the contact surface between the upper cover 4 and the swing rod 3 to achieve the purpose of increasing the damping force. Of course, only making the upper cover 4 and the swing rod 3 rub against each other requires a high degree of magnetism of the magnet, and a strong magnetic force is required to meet sufficient friction force. For this reason, in this embodiment, damping material is preferably provided between the swing rod 3 and the base 1, and the base 1 is also a magnetic material, so that friction damping can be generated on the upper and lower surfaces of the swing rod 3 to provide sufficient damping force for the swing rod. However, in the specific use process, long-term friction will also cause wear of the base 1. In order to facilitate the maintenance of the entire wind brace, in this embodiment, a lower sealing plate 2 is preferably provided between the swing rod 3 and the base 1, and damping material is preferably provided between the lower sealing plate 2 and the swing rod 3. The damping material can also be compounded on the contact surface between the lower sealing plate 2 and the swing rod 3. Therefore, after using for a long enough time, when the upper cover plate and the lower sealing plate 2 are greatly worn and cannot provide sufficient damping force, the upper cover 4 and the lower sealing plate 2 can be disassembled and replaced. Compared with the overall replacement after the base is worn, the maintenance cost is lower and faster. Of course, it should be noted that a first avoidance hole 21 and a second avoidance hole 22 are provided in the middle of the lower sealing plate 2. The first avoidance hole 21 allows the shaft 11 to pass through without affecting the installation of the swing rod 3, and the second avoidance hole 22 allows the screw 7 to pass through and be screwed into the screw hole 13 of the base. It should be noted that the damping material can be selected from high damping alloys in the prior art, such as copper-zinc-aluminum alloys, iron-chromium-molybdenum alloys and manganese-copper alloys, and the damping material is pressed into a sheet and composited on the upper cover and the lower sealing plate 2 by bonding or the like. Of course, other damping materials such as rubber can also be used.

[0024] In addition, in this embodiment, while providing reliable contact through the magnetic force of the magnet, it is also possible to compensate for the amount of wear generated during use, thereby maintaining a stable and consistent damping force for a long time.

[0025] When the opening of the window sash 10 needs to be adjusted, it is only necessary to apply sufficient driving force to overcome the damping force of the wind brace to push the window sash outward or inward. When the window sash 10 is in place, the damping force of the wind brace itself can keep the window sash in the current position. Compared with the traditional technology that requires positioning at a specific position to achieve the opening adjustment, the present application can achieve stepless adjustment of the window sash opening.

[0026] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
