Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic doors and windows, and particularly relates to a new type of multifunctional aluminum-plastic door and window. Background Art

[0002] Aluminum-plastic doors and windows, also known as aluminum alloy doors and windows, are widely used in families, hotels, high-rise buildings, etc. When processing and producing aluminum-plastic doors and windows, considering that rainwater will flow into the glass along the window frame slideway on rainy days, drainage holes are usually arranged on the side of the lower end of the window frame close to the outside. And in order to prevent rainwater from flowing back, a drainage hole cover is installed on the drainage hole. The existing drainage hole cover includes a drainage hole cover body. The drainage hole cover body includes a rectangular fixing plate and a long baffle and two short baffles respectively fixed to three sides of the rectangular fixing plate. A drainage port is arranged on the side of the drainage hole cover body far from the long baffle. A pair of elastic clamping parts on the same side as the long baffle or the end baffle are fixed on the rectangular fixing plate. The elastic clamping parts are inclined at a certain angle in opposite directions. The elastic clamping part includes a support rod with one end fixed to the rectangular fixing plate and a clamping part fixed to the other end of the support rod and in a triangular shape extending in the inclined direction of the support rod.

[0003] A drainage hole cover for aluminum-plastic doors and windows is disclosed in the Chinese utility model patent with the publication number of CN207863811U. The key points of its technical solution are: including a drainage hole cover body, the drainage hole cover body includes a rectangular fixing plate and a long baffle and two short baffles respectively fixed to three sides of the rectangular fixing plate and having the same height. A drainage port is arranged on the side of the drainage hole cover body far from the long baffle. A pair of elastic clamping parts on the same side as the long baffle or the short baffle are fixed on the rectangular fixing plate. A separating part for preventing insects from entering and allowing water flow through is arranged at the drainage port. The advantage of the utility model is that it can prevent insects with smaller volumes from entering the room on the premise of realizing the drainage function.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: The above device installs the separating part by inserting the sliding parts on both sides of the separating part into the slideways on both sides of the short baffle. When the staff needs to replace or clean the separating part, the staff needs to remove the drainage hole cover body from the window frame, and then slide and remove the separating part in the drainage hole cover along the direction away from the fixing plate. The operation is relatively cumbersome and the use experience is poor. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a new type of multifunctional aluminum-plastic door and window.

[0006] The above technical object of the present utility model is achieved through the following technical solutions: A new type of multifunctional aluminum-plastic door and window, including a door and window main body. Drainage holes are provided on the side wall of the door and window main body. A drainage hole cover for preventing rainwater backflow is provided on the side wall of the door and window main body. T-shaped grooves are provided at both ends of the side wall of the drainage hole cover away from the door and window main body. Slide bars are slidably arranged in the two T-shaped grooves. An annular plate is jointly installed on the bottom surfaces of the two slide bars. An insect-proof net is arranged on the inner wall of the annular plate. A limiting component for limiting the slide bars is arranged on the drainage hole cover.

[0007] By adopting the above technical solutions, when the staff installs the door and window main body, the staff only needs to make the drainage hole cover be clamped and fixed with the door and window main body, then the drainage hole cover can cover the drainage hole, and thus the water flow on the window frame flows through the drainage hole and is discharged through the drainage hole cover. During this process, the staff needs to connect the slide bar with the T-shaped groove and activate the limiting component, then the limiting component can block the annular plate, so that the insect-proof net is kept stable, thereby reducing the probability of flying insects entering the room through the drainage hole, and improving the use experience of the staff. When the staff needs to replace or clean the insect-proof net, the staff only needs to close the limiting component and slide the slide bar, then the slide bar can be separated from the T-shaped groove without removing the drainage hole cover, thus reducing the operation difficulty of the staff.

[0008] Furthermore, a first sliding groove is provided on the side wall of the drainage hole cover away from the door and window main body. Second sliding grooves communicating with the vertical parts of the two T-shaped grooves are respectively provided on the opposite inner walls of the first sliding groove. The limiting component includes a sleeve fixed on the inner wall of the drainage hole cover with one side open, a first limiting rod slidably arranged in the first sliding groove, and a second limiting rod slidably arranged in the second sliding groove. Inclined surfaces are provided on the edges where the side walls of the two second limiting rods close to each other intersect with the side walls away from the door and window main body. The first limiting rod is slidably connected with the sleeve.

[0009] By adopting the above technical solutions, when the staff connects the slide bar with the T-shaped groove, the staff only needs to connect the first limiting rod with the first sliding groove and push the first limiting rod, then the first limiting rod can simultaneously press against the two inclined surfaces. At this time, the staff only needs to continue to push the first limiting rod, then the two second limiting rods can move in opposite directions under the action of the first limiting rod, so that the two second limiting rods respectively move into the two T-shaped grooves, and further the two second limiting rods respectively block the two slide bars. Subsequently, the first limiting rod crosses the inclined surface and finally presses against the inner wall of the sleeve. At this time, the staff only needs to release the first limiting rod, then the second limiting rod can be kept stable.

[0010] Further, a limiting groove is formed in the inner top wall of the second sliding groove. A limiting block is slidably arranged in the limiting groove. A limiting spring is fixed to the side wall of the limiting block. The other end of the limiting spring is fixed to the inner wall of the limiting groove. The limiting block is fixed to the second limiting rod.

[0011] By adopting the above technical solution, when the staff separates the first limiting rod from the first sliding groove, the two second limiting rods are reset under the action of the two limiting springs respectively, and then the second limiting rods are separated from the T-shaped grooves. At this time, the staff only needs to slide the annular plate to separate the sliding rod from the T-shaped groove, thus reducing the operation difficulty of the staff.

[0012] Further, the length of the first limiting rod is equal to the sum of the depth of the first sliding groove and the depth of the inner wall of the sleeve.

[0013] By adopting the above technical solution, when the first limiting rod moves to the farthest end, that is, when the first limiting rod abuts against the inner wall of the sleeve, the side wall of the first limiting rod away from the door and window main body is flush with the side wall of the drain hole cover, thus improving the stability of the first limiting rod.

[0014] Further, a receiving groove is formed in the side wall of the first limiting rod. A placement rod is slidably arranged in the receiving groove. A fixing spring is fixed to the inner wall of the receiving groove. The side wall of the placement rod away from the fixing spring is flush with the side wall of the first limiting rod. A connecting rope is fixed to the side wall of the placement rod close to the fixing spring. The other end of the connecting rope is fixed to the inner wall of the receiving groove.

[0015] By adopting the above technical solution, when the staff needs to replace the insect-proof net, the staff needs to separate the first limiting rod from the first sliding groove. At this time, the staff needs to press the placement rod to continuously compress and store energy in the fixing spring. Subsequently, the staff needs to quickly release the placement rod, and one end of the placement rod can pop out under the action of the fixing spring. Further, the staff needs to pull the placement rod, and the first limiting rod can move along with the placement rod under the action of the connecting rope, thus reducing the operation difficulty of the staff.

[0016] Further, the connecting rope is a connecting rope made of an elastic cord.

[0017] Further, a fillet is arranged on the side wall of the first limiting rod close to the door and window main body.

[0018] By adopting the above technical solution, the probability of damage to the inclined surface is reduced, which is beneficial to extending the service life of the second limiting rod.

[0019] Further, the fixing spring is a fixing spring made of stainless steel spring wire.

[0020] By adopting the above technical solution, a stainless steel spring refers to a spring that can work in weak corrosive media such as electronics, air, steam, water, and chemical corrosive media such as acids, alkalis, and salts. The fixed spring made of stainless steel spring wire has good corrosion resistance, thereby reducing the probability of rusting of the fixed spring.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] 1. In this application, when the staff installs the door and window main body, the staff only needs to make the drain hole cover be clamped and fixed with the door and window main body, then the drain hole cover can cover the drain hole, and thus the water flow on the window frame can flow through the drain hole and be discharged through the drain hole cover. During this process, the staff needs to connect the sliding rod with the T-shaped groove and start the limiting component, then the limiting component can block the annular plate, so that the insect-proof net is kept stable, thereby reducing the probability of flying insects entering the room through the drain hole, and further improving the use experience of the staff. When the staff needs to replace or clean the insect-proof net, the staff only needs to turn off the limiting component and slide the sliding rod, then the sliding rod can be separated from the T-shaped groove without removing the drain hole cover, thus reducing the operation difficulty of the staff;

[0023] 2. In this application, when the staff connects the sliding rod with the T-shaped groove, the staff only needs to connect the first limiting rod with the first chute and push the first limiting rod, then the first limiting rod can simultaneously press against the two inclined surfaces. At this time, the staff only needs to continue to push the first limiting rod, then the two second limiting rods can move away from each other under the action of the first limiting rod, so that the two second limiting rods respectively move into the two T-shaped grooves, and thus the two second limiting rods respectively block the two sliding rods. Subsequently, the first limiting rod crosses the inclined surface and finally presses against the inner wall of the sleeve. At this time, the staff only needs to release the first limiting rod, then the second limiting rod can be kept stable;

[0024] 3. In this application, when the staff separates the first limiting rod from the first chute, the two second limiting rods respectively reset under the action of the two limiting springs, and thus the second limiting rods are separated from the T-shaped groove. At this time, the staff only needs to slide the annular plate, then the sliding rod can be separated from the T-shaped groove, thus reducing the operation difficulty of the staff.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0034] As Figure 1-7 shown, an embodiment of the present application discloses a new type of multifunctional aluminum-plastic door and window, including a door and window main body 1, a drain hole 11 cover, a sliding rod 3, an annular plate 31, an insect-proof net 4, a limiting component 5, a limiting block 61, a limiting spring 7, a placement rod 8, a fixing spring 81, and a connecting rope 9. A drain hole 11 is opened on the side wall of the door and window main body 1, and a drain hole cover is arranged on the side wall of the door and window main body 1 to prevent rainwater from flowing back. T-shaped grooves 21 are opened at both ends of the side wall of the drain hole cover away from the door and window main body 1. The sliding rod 3 is a rod-shaped structure with a T-shaped cross-section, and there are two sliding rods 3 which are respectively slidably arranged in the two T-shaped grooves 21. The annular plate 31 is a plate-shaped structure with a square annular cross-section, and the annular plates 31 are commonly installed on the bottom surfaces of the two sliding rods 3. The insect-proof net 4 is arranged on the inner wall of the annular plate 31 to block mosquitoes.

[0035] On the side wall of the cover of the drain hole 11 away from the door and window main body 1, a first sliding groove 41 is opened. On the opposite inner walls of the first sliding groove 41, second sliding grooves 42 communicating with the vertical parts of the two T-shaped grooves 21 are respectively opened. The limiting component 5 is arranged on the cover of the drain hole 11 and is used for limiting the sliding rod 3. The limiting component 5 includes a sleeve 51, a first limiting rod 52 and a second limiting rod 53. The sleeve 51 is a cuboid structure with one side open, and the sleeve 51 is fixed on the inner wall of the cover of the drain hole 11. The first limiting rod 52 is a rectangular rod-shaped structure. The first limiting rod 52 is slidably arranged in the first sliding groove 41, and the first limiting rod 52 is slidably connected with the sleeve 51. The second limiting rod 53 is a rectangular rod-shaped structure. There are two second limiting rods 53, which are respectively slidably arranged in the two second sliding grooves 42, and inclined surfaces are opened on the edges where the side walls of the two second limiting rods 53 close to each other intersect with the side walls away from the door and window main body 1.

[0036] When the staff connects the sliding rod 3 with the T-shaped groove 21, the staff only needs to connect the first limiting rod 52 with the first sliding groove 41 and push the first limiting rod 52, then the first limiting rod 52 can simultaneously abut against the two inclined surfaces. At this time, the staff only needs to continue to push the first limiting rod 52, and the two second limiting rods 53 can move away from each other under the action of the first limiting rod 52, so that the two second limiting rods 53 respectively move into the two T-shaped grooves 21, and further the two second limiting rods 53 respectively block the two sliding rods 3. Subsequently, the first limiting rod 52 crosses the inclined surface and finally abuts against the inner wall of the sleeve 51. At this time, the staff only needs to release the first limiting rod 52 to keep the second limiting rod 53 stable.

[0037] On the inner top wall of the second sliding groove 42, a limiting groove 6 is opened. The limiting block 61 is a rectangular block structure. The limiting block 61 is slidably arranged in the limiting groove 6, and the limiting block 61 is fixedly connected with the second limiting rod 53. One end of the limiting spring 7 is fixed on the side wall of the limiting block 61, and the other end of the limiting spring 7 is fixedly connected with the inner wall of the limiting groove 6.

[0038] When the staff separates the first limiting rod 52 from the first sliding groove 41, the two second limiting rods 53 are respectively reset under the action of the two limiting springs 7, and then the second limiting rods 53 are separated from the T-shaped grooves 21. At this time, the staff only needs to slide the annular plate 31 to separate the sliding rod 3 from the T-shaped groove 21, thus reducing the operation difficulty of the staff.

[0039] To improve the stability of the first limiting rod 52, the length of the first limiting rod 52 is equal to the sum of the depth of the first sliding groove 41 and the depth of the inner wall of the sleeve 51. When the first limiting rod 52 moves to the farthest end, that is, when the first limiting rod 52 abuts against the inner wall of the sleeve 51, the side wall of the first limiting rod 52 away from the door and window main body 1 is flush with the side wall of the drainage hole 11 cover, thereby improving the stability of the first limiting rod 52.

[0040] A receiving groove 71 is formed on the side wall of the first limiting rod 52. The placement rod 8 is in a rectangular rod shape and is slidably arranged in the receiving groove 71. One end of the fixing spring 81 is fixed on the inner wall of the receiving groove 71, and the side wall of the placement rod 8 away from the fixing spring 81 is flush with the side wall of the first limiting rod 52. One end of the connecting rope 9 is fixed on the side wall of the placement rod 8 close to the fixing spring 81, and the other end of the connecting rope 9 is fixedly connected to the inner wall of the receiving groove 71, and the connecting rope 9 is made of an elastic cord.

[0041] When the staff needs to replace the insect-proof net 4, the staff needs to separate the first limiting rod 52 from the first sliding groove 41. At this time, the staff needs to press the placement rod 8, so that the fixing spring 81 can be continuously compressed and energy can be stored. Subsequently, the staff needs to quickly release the placement rod 8, and one end of the placement rod 8 can pop out under the action of the fixing spring 81. Further, the staff needs to pull the placement rod 8, so that the first limiting rod 52 can move following the placement rod 8 under the action of the connecting rope 9, thereby reducing the operation difficulty of the staff.

[0042] To reduce the probability of damage to the inclined surface, which is beneficial to extending the service life of the second limiting rod 53, a rounded corner is provided on the side wall of the first limiting rod 52 close to the door and window main body 1.

[0043] To reduce the probability of rusting of the fixing spring 81, the fixing spring 81 is made of stainless steel spring wire. A stainless steel spring refers to a spring that can work in weak corrosive media such as electronics, air, steam, and water, and chemical corrosive media such as acids, alkalis, and salts. The fixing spring 81 made of stainless steel spring wire has good corrosion resistance, thereby reducing the probability of rusting of the fixing spring 81.

[0044] In this embodiment, the working principle of a new type of multifunctional aluminum-plastic door and window is as follows: When the staff installs the door and window main body 1, the staff only needs to snap and fix the drain hole 11 cover to the door and window main body 1, so that the drain hole 11 cover can cover the drain hole 11, and then the water flow on the window frame can flow through the drain hole 11 and be discharged through the drain hole 11 cover. During this process, the staff needs to connect the sliding rod 3 with the T-shaped groove 21 and start the limit component 5, so that the limit component 5 can block the annular plate 31, thereby keeping the insect screen 4 stable, and further reducing the probability of flying insects entering the room through the drain hole 11, and thus improving the use experience of the staff. When the staff needs to replace or clean the insect screen 4, the staff only needs to turn off the limit component 5 and slide the sliding rod 3, so that the sliding rod 3 can be separated from the T-shaped groove 21 without removing the drain hole 11 cover, thereby reducing the operation difficulty of the staff.

[0045] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
