Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy doors and windows, in particular to a safe aluminum alloy door and window. BACKGROUND

[0002] The aluminum alloy door and window is a commonly used home building material equipment, mainly used for indoor lighting and ventilation to improve indoor light and air circulation and other conditions to meet people's needs for indoor lighting, ventilation, noise reduction, heat insulation, etc. It uses connecting rods, slide rails and other mechanisms to control the opening and closing of the window. The equipment is mainly used in the field of home building materials, and the selected window frame material is mostly aluminum alloy.

[0003] Today's door and window products are roughly divided into three types: out-opening, in-opening and flat-opening. The in-opening and out-opening doors and windows are supported and opened and closed by connecting rod mechanisms, and the main opening and closing method relies on the installation position of the connecting rod mechanism to control the inward opening, outward opening, left opening and right opening of the window. The flat-opening door and window uses the window frame bottom to slide and connect to the slide rail of the door frame, and the distance of the window opening and closing is limited by the frame on both sides to achieve movement.

[0004] The out-opening aluminum alloy door and window opens and closes the window manually, applies a certain force to the window, and transmits the force to the sliding block through the connecting rod to complete the reciprocating motion of the sliding block and achieve the opening and closing action of the window. However, this type of door and window also has defects. In some coastal areas, monsoon climate zones and even high-rise residences that often encounter strong winds, incidents of window falling due to strong winds often threaten people's safety. Although there are currently devices on the market to prevent window falling, such as anti-falling ropes or additional window opening and closing limiters to reduce the opening angle of the window to avoid falling due to strong winds, these devices do not solve the problem from the root, but some devices hinder the function of the window itself, and the repair cost caused by the falling window is also a considerable expense.

[0005] Therefore, in order to ensure that the window can safely complete the mechanical automatic closing in the case of strong wind and protect the safety of life, a safe aluminum alloy door and window is proposed. SUMMARY

[0006] The purpose of the present application is to provide a safe aluminum alloy door and window to solve the problem of window damage caused by strong winds. Specifically, the force formed by the wind blowing on the window is controlled by the control assembly to unlock the locking assembly, so that the window can complete the mechanical automatic closing function, and the deceleration assembly can slow down the window during the rapid closing process, thereby protecting the safety of the window itself.

[0007] To achieve the above purpose, the present application provides the following technical scheme:

[0008] The utility model provides a safe type aluminum alloy door and window, including window frame, movable sash, first connecting rod, pivot, control rod, sliding slot, slide rail and handle, the sliding slot is seted up in window frame, the slide rail is installed in the sliding slot, the slide rail is rotatably installed with pivot and first connecting rod, pivot and first connecting rod are rotatably installed with movable sash, control rod is rotatably connected between window frame and movable sash, control rod includes fixed rod and movable rod, and fixed rod and movable rod are connected on window frame and movable sash respectively, locking assembly is connected between fixed rod and movable rod, handle and control assembly are connected on movable sash, and when movable sash is subjected to the setting pressure, control assembly releases the fixing of fixed rod and movable rod of locking assembly, and deceleration assembly is connected between window frame and movable sash.

[0009] It can be known that there are many kinds of mechanisms to realize the locking of doors and windows, including the locking of window opening and closing through the control of motor chain wheel and chain or the connection of fixed seat and fixed rod, but compared with the above two mechanisms, one is that the space for installing motor and chain wheel is not needed, avoiding the conflict between installation space and indoor space, and also reducing the cooperation between various structures and the installation cost, and the other is that the additional power source is not needed, that is, the additional power supply control motor is not needed to control the opening and closing of the window, the designed scheme can complete the mechanical closing of the window by relying on wind in windy weather, has environmental protection, and compared with the motor, the designed scheme is more convenient to install, has lower cost, and is more suitable for people to ensure the safety state of windows and home environment when not at home in bad weather after work.

[0010] Preferably, the locking assembly comprises a clamping block, a mounting rod, a spring, a wedge block, a push rod and a guide rod, two mounting rods are symmetrically movably installed in the movable rod, the two mounting rods are connected with the movable rod through the guide rod, the ends of the two mounting rods close to the fixed rod are fixedly installed with clamping blocks matched with the fixed rod, mounting grooves are formed in the clamping blocks, and clamping blocks are elastically installed in the mounting grooves, the clamping blocks are matched with the clamping grooves formed in the fixed rod, the two mounting rods are connected with the movable rod through the spring, the ends of the two mounting rods away from the clamping blocks are fixedly installed with wedge blocks, and the movable rod movably installs a push rod matched with the two wedge blocks.

[0011] The part of the mounting rod close to the push rod one is fixedly provided with wedge-shaped blocks, the two wedge-shaped blocks are matched with the push rod one, the mounting rod is fixedly connected with the moving lever through the spring one, and the mounting rod is fixedly connected with the clamping block at the tail end, the clamping block is locked to the fixed rod under the condition that no external force is affected, the clamping block and the fixed rod are matched with each other, and the clamping block is further clamped and fixed to the fixed rod, when the push rod one is affected by the set external force, the push rod one moves to the wedge-shaped blocks, the mounting rod is compressed after being affected by the pressure of the wedge-shaped blocks, the spring one is compressed as a fulcrum, the clamping block moves to both sides, the clamping block is separated from the clamping groove, and the clamping block is unlocked to the fixed rod.

[0012] It can be known that there are many control mechanisms for unlocking the door and window locking assembly, including electric intelligent control or manual triggering. Compared with the above two measures, the present application has the following advantages: 1. The additional power supply and control system increase the use cost and later maintenance cost of people; 2. If the control is manual, there are many uncertain factors, for example, the reaction is not in time or people are not at home to take effective measures to unlock the window, and if the environment is bad, the window may be damaged in a short time, threatening the safety of pedestrians and causing property loss.

[0013] Preferably, the control assembly comprises a piston rod one, a spring two, a fixed block, a piston rod two, a piston cylinder, a handle, a button, a spring three, a pressing plate, an air bag and an air pipe one, two fixed blocks are symmetrically and fixedly installed on the inner side wall of the movable rod, the spring two is connected between the two fixed blocks and the piston rod one, the piston cylinder is fixedly installed in the movable rod, the piston rod one and the piston rod two are connected at two ends of the piston cylinder, and the push rod one is fixedly connected to the piston rod two, the piston cylinder is divided into a large inner diameter end and a small inner diameter end according to the size of the inner diameters at two ends, and the piston rod one and the piston rod two are matched with the large inner diameter end and the small inner diameter end respectively, one end of the piston rod one extends to the outer side of the movable rod and is rotationally connected with the movable window sash; the air bag, the spring three and the pressing plate are installed in the movable window sash, the pressing plate is connected to one side of the air bag through the spring three, the button for pushing the pressing plate is connected to the handle, the air pipe one is connected to the air bag, the air pipe one is in communication with the piston cylinder, and the air pipe one is located between the piston rod one and the piston rod two.

[0014] The handle of the movable window sash and the piston in the movable rod jointly complete the control of the switch window. When the window is opened, the hand presses the button, overcomes the tension of the spring three to make the pressing plate extrude the air bag, the gas in the air bag is discharged into the piston cylinder through the air pipe one, the piston rod two is driven to move the push rod one to the wedge block because the spring is installed on the piston rod one, and the piston cylinder is close to the small diameter end of the wedge block, so that the piston rod two can obtain a large stroke of the moving amount. When the push rod one moves to the set position, the locking assembly is unlocked, and the opening of the window is completed. When the hand releases the button, the pressing plate is pushed back to the initial position by the tension of the spring three, and then the air bag returns to the original form, so that the gas in the piston cylinder is discharged, the piston rod two drives the push rod one to retract, and the clamping block completes the locking of the fixed rod.

[0015] When the window encounters strong wind, the piston rod one is extruded into the piston cylinder by overcoming the tension of the spring two, at this time, due to the limitation of the air bag material and the tension of the spring three, the air bag cannot be inflated, so that the air in the piston cylinder drives the piston rod two to move, promotes the push rod one to move to the wedge block, and the locking assembly is unlocked, and the closing of the window is completed. If the speed is too fast during the closing of the window, the speed reduction assembly will play a role to complete the speed reduction and protect the safety of the window.

[0016] It can be seen that there are many speed reduction mechanisms for opening and closing doors and windows, including installing damping spring mechanisms or door closers. However, compared with the present scheme, the installation of other mechanisms will increase the occupation of the space of the window frame area, and the increased mechanism will also affect the opening of the window.

[0017] Preferably, the speed reduction assembly comprises a pneumatic push rod, an air cylinder, a spring four, a gas resistance sheet and an air pipe two, the movable rod is rotationally connected with the pneumatic push rod, the pneumatic push rod is slidably connected in the air cylinder, the bottom of the air cylinder is rotationally connected on the slide rail, the bottom of the air cylinder is provided with an air hole, and the air hole is fixedly installed with the air pipe two, the air pipe two is provided with an air outlet hole and an air inlet hole, and the air inlet hole is installed with a filter screen, and the air inlet hole and the air outlet hole are connected with a one-way valve, the bottom of the air cylinder is provided with a cavity, and the inner walls of the two sides of the cavity are fixedly installed with the spring four close to the air hole, and the free ends of the two spring fours are fixedly connected with the gas resistance sheet.

[0018] In the above scheme, the movement of the deceleration assembly relies on the control rod to complete the pull-type reciprocating motion caused by the opening and closing of the door and window. When the window is opened manually, the movable rod of the control rod moves outward, driving the pneumatic push rod to slide away from the air cylinder. At this time, the air suction of the air cylinder will not be affected by the air resistance piece, causing difficulty in opening the window. Moreover, the air suction process will not be affected by the filter screen, so as not to suck in dust particles and damage the stability of the mechanism itself. When the window is closed quickly manually or in an emergency due to strong wind, the control assembly completes the unlocking of the locking assembly, so that the clamping block moves away from the fixed rod. At this time, the movable rod retracts inward, driving the pneumatic push rod to slide quickly into the air cylinder. The high-pressure gas generated moves quickly towards the air hole. At this time, the air resistance piece will move towards the air hole under the action of the rapid gas flow and block the air hole, completing the slow exhaust and generating high-pressure gas in the air cylinder to achieve the deceleration effect on the movable window sash. The exhaust gas passes through the cleaning assembly to complete the cleaning of the contact section of the fixed rod and the movable rod.

[0019] It can be seen that there are many mechanisms or measures to clean the door and window sliding rails and other parts, but generally they are cleaned manually with the help of some tools. Compared with manual cleaning, the measures adopted in the present scheme automatically complete cleaning through the airflow formed by the deceleration assembly during the opening and closing of the window. Nowadays, with the development of life, people's work and life are increasingly busy, and it is inevitable to forget such things, resulting in more dust accumulation in the sliding rails or mechanism sliding connections, which affects the related mechanisms and the use effect of the window in the long run.

[0020] Preferably, the cleaning assembly comprises a shunt pipe, the shunt pipe is fixedly connected to the air pipe II, and fine holes are formed on the left and right sides of the shunt pipe, and the fine holes are vertically directed to the fixed rod and the movable rod.

[0021] In the above scheme, when the door and window are closed, the deceleration assembly completes the retraction action. The gas sucked into the air cylinder during the opening of the window moves to the fine hole during the retraction of the pneumatic push rod. Due to the small size of the fine hole, the gas output is small, which further slows down the closing speed of the movable window sash. At this time, the high-pressure airflow generated in the air cylinder is accelerated and sprayed from the fine hole, completing the cleaning of the dust and other impurities at the connection between the fixed rod clamping groove and the movable rod.

[0022] It can be seen that there are many parts to achieve the clamping and fixation of the clamping block to the fixed rod, such as the use of balls and grooves. However, compared with the scheme adopted in the present invention, when the balls and grooves are used, the cooperation is not unidirectional in the case of window closing with the help of wind. When the wind direction is outdoor, the clamping block will still overcome the elastic force of the balls and separate from the fixed rod, causing the window to be pulled outward.

[0023] Preferably, the locking structure of the clamping block to the fixed rod comprises a clamping groove on the fixed rod, a mounting groove in the clamping block and a clamping block mounted in the mounting groove, the clamping block has a slope at the front end, and the slope points to the window frame, and the clamping block and the clamping groove are matched with each other.

[0024] In the above scheme, when the clamping block is inserted into the clamping groove, the mounting rod is clamped by the clamping block under the action of the spring, at this time, if a strong wind blows, the side of the front end of the clamping block other than the slope matches with the clamping groove, at this time, the clamping block is placed in the clamping groove, so that the movable rod cannot be separated from the locking of the clamping block to the fixed rod, thereby preventing the window from being opened by the wind; when the wind blows indoors, if the spring is disabled due to aging of the door and window, the wind force presses the movable rod through the movable window sash, the slope of the clamping block in the movable rod is pressed with the clamping groove, when the pressure exceeds the set value, the clamping block is separated from the clamping groove, so that the window starts to close, if the wind force decreases during the closing of the window, the clamping block is inserted into the clamping groove, and the fixed rod is fixed, so that the window continues to ventilate.

[0025] Compared with the prior art, the beneficial effects of the present application are:

[0026] 1. In the areas along the river and the coast and high-rise residential buildings, accidents of window damage and falling caused by strong wind often occur, which endanger the safety of pedestrians, therefore, a door and window capable of automatically closing the window mechanically in strong wind is designed; the existing door and window opening and closing mechanism basically adopts an intelligent control system to monitor weather changes and control the mechanical structure, so that the door and window are automatically opened and closed, but such equipment is expensive and is not used by most people, and the scheme adopted in the present application is that the locking assembly, the control assembly, the speed reduction assembly, the cleaning assembly and the handle are cooperated to realize different closing functions of the window in manual mode and in strong wind weather.

[0027] 2、The advantages of the present application are: first, through the control lever itself setting components, complete the window opening angle locking, realize the window in open to not more than the limit range of any angle can be achieved locking; second, when the window is opened if encounter extreme weather, can through the control assembly to remove the locking assembly on the fixed rod unlocking, realize the mechanical type automatic closing window function; third, because the control assembly to remove the locking assembly has two ways, so through the setting of this path, can make in manual case can easily complete the opening and closing of the window, and in the wind case, the wind can only complete the closing of the window, but can't make the window open again; fourth, when the window closing speed is too fast, can through the speed reduction assembly complete the speed reduction effect of window closing, play the role of window protection, also can use the airflow generated by the speed reduction assembly to complete the cleaning effect of the fixed rod card slot and the contact section of the movable rod by the cleaning assembly; fifth, the clamping block installed in the slot and the fixed rod card slot cooperate with each other, realize the fixed clamping of the fixed rod; sixth, when the control assembly spring fails, under the action of wind force, the movable sash is pressed to extrude the movable rod, the inclined surface of the movable rod inner clamping block extrudes the clamping groove, still can make the movable rod shrink to the fixed rod, complete the closing of the window, in this process, the speed reduction assembly still plays the role of speed reduction, at this time, if the window is not completely closed, the clamping block and the clamping groove cooperate with each other, so that the wind can't open the movable sash again.

[0028] 3、The existing door and window locking mechanism, most of them adopt installing window opening limiter or locking seat and lock body assembly to complete the control and locking of the window opening angle, but these mechanisms usually need manual unlocking of the locking mechanism, at this time, when people are not at home, it may cause threat to the window in the event of an emergency and affect the safety of pedestrians, while the mechanism designed in the present application can rely on wind force to close the window when people are not at home, when the window is not completely closed and the wind speed decreases to a certain extent, spring two will push piston rod one back to the initial position, at this time, piston rod two with push rod one retract, the clamping block restores the locking of the fixed rod, continues to make the window complete the ventilation function, and the locking assembly completes the unlocking control assembly, according to the manual opening and closing of the window and the wind closing of the window, through the setting of different parts, realize the unlocking of the locking assembly through different paths in different opening and closing conditions of the window, when manually opening and closing the window, press the button, make the pressing plate in the movable sash extrude the air bag, discharge the gas in the air bag into the piston cylinder through the air pipe one, piston rod two drives push rod one to move towards the wedge-shaped block, complete the unlocking of the clamping block to the fixed rod, realize the opening and closing of the window; in the wind case, piston rod one extrudes the spring to move towards the piston cylinder, the extruded high pressure gas drives piston rod two to move towards the wedge-shaped block, complete the unlocking of the clamping block to the fixed rod, realize the closing of the window.

[0029] The existing door and window closing emergency deceleration mechanism mostly adopts the assembly of slide bar and slide support or installs the door and window decelerator. For these devices, money is needed to purchase and the space of indoor wall is occupied to complete the installation of the decelerator fixing device. This not only occupies the indoor space, but also affects the aesthetic appearance. The installation of these mechanisms also causes certain influence on the window opening and destroys the use feeling. The mechanism designed in the application mainly drives the deceleration assembly to complete the door and window rapid closing by the movement of the movable rod on the control rod. The airflow generated in the movement process of the deceleration assembly can complete the cleaning of the dust and sundries at the fixed rod clamping groove and movable rod cooperation place through the cleaning assembly.

The advantage of setting such a door and window dual-channel closing mechanism is that it avoids the situation that manual window opening needs to overcome the tension of the spring 81, and also enables the window to be closed under strong wind without the control of the handle 9. Under strong wind, the window can only be closed by extruding the spring 81 by the piston rod 80 to complete the unlocking of the locking assembly 10 by the control assembly 8, so that the window is closed. At this time, even if the spring 81 fails due to rust or other reasons, under the influence of strong wind, the movable sash 2 extrudes the movable rod 50, the inclined surface of the clamping block 1001 in the movable rod 50 extrudes the clamping groove 510, the movable rod 50 moves to the fixed rod 51, and the window is closed, thereby avoiding accidents. If the window is not completely closed due to the decrease of wind force at this time, the clamping block 1001 will be reinserted into the clamping groove 510. At this time, if the wind blows from the indoor to the outdoor, the side of the clamping block 1001 close to the movable sash 2 tightly fits with the clamping groove 510, and the wind cannot complete the window opening action.

[0054] As an embodiment of the present application, referring to Figure 4 , the movable sash 2 is provided with a handle 90, the movable sash 2 is provided with a spring 92, a pressing plate 93, a gas bag 94 and a gas pipe 95, the handle 90 is connected with a button 91 for pushing the pressing plate 93, the pressing plate 93 and the movable sash 2 frame are provided with the spring 92 matched with the button 91, when the button 91 is triggered, the pressing plate 93 extrudes the gas bag 94, the gas in the gas bag 94 is discharged into the piston cylinder 84 of the control assembly 8 through the gas pipe 95, the piston rod 83 extrudes the wedge block 103 with the push rod 104, the unlocking of the locking assembly 10 to the fixed rod 51 is completed, and the window is closed.
