Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, and in particular to a novel hidden lower drainage structure. Background Art
[0002] As an important part of a building, building doors and windows have a significant impact on the quality of the indoor environment. At present, in order to prevent water accumulation in the door and window frames, setting up drainage mechanisms on doors and windows has become one of the design specifications for doors and windows, especially for building exterior doors and windows.
[0003] However, the drainage holes used in existing conventional hidden drainage structures are usually directly connected to the outdoor side. When the wind pressure is high, rainwater can easily flow back from the drainage holes into the room, causing water seepage. In addition, the positions of existing drainage holes are relatively deep, which makes it difficult to spray the paint on the profiles, which can easily cause oxidation corrosion and affect the service life of the equipment. Utility Model Content
[0004] The purpose of the utility model is to provide a novel hidden lower drainage structure in view of the shortcomings and defects in the prior art. The drainage holes adopted in the lower drainage structure are staggered openings, which can effectively prevent indoor and outdoor air convection, thereby avoiding rainwater backflow and indoor water seepage. It is also convenient for spraying paint, effectively avoiding oxidation corrosion of the profile, and increasing the overall service life of the profile.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of hidden lower drainage structure, which includes a hidden frame 1 installed in the wall with a hidden effect, thermal insulation cotton 2 with thermal insulation effect and an outer frame 4 with drainage holes, the inner side of the outer frame 4 is connected to the hidden frame 1 through the thermal insulation cotton 2, and the side of the thermal insulation cotton 2 is installed with an insulation strip 3, and the outer frame 4 is provided with an outer drainage hole 7 and an inner drainage hole 8 for drainage.
[0006] Furthermore, a middle rubber strip 5 for increasing the air tightness of the device is provided at the connection between the outer frame 4 and the hidden frame 1 .
[0007] Furthermore, a water cavity A is provided on the outer frame 4, and an outer drainage hole 7 and an inner drainage hole 8 are respectively opened on two adjacent walls of the water cavity A.
[0008] Furthermore, the outer drainage hole 7 and the inner drainage hole 8 are opened in a staggered manner.
[0009] Furthermore, a heat insulation strip 3, thermal insulation cotton 2 and a heat insulation strip 3 are sequentially arranged between the hidden frame 1 and the outer frame 4 from the outside to the inside.
[0010] Furthermore, a lower rail 6 is installed on one side of the hidden frame 1 .
[0011] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the drainage holes adopted in the lower drainage structure are staggered openings, which can effectively prevent indoor and outdoor air convection, thereby avoiding rainwater backflow, avoiding indoor water seepage, and facilitating spraying of paint, effectively avoiding oxidation corrosion of the profile, and increasing the overall service life of the profile.

[0017] Embodiment 1
[0018] See also Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: it includes a hidden frame 1 with a hidden effect installed in the wall, thermal insulation cotton 2 with thermal insulation effect and an outer frame 4 with drainage holes, the inner side of the outer frame 4 is connected to the hidden frame 1 through the thermal insulation cotton 2, and the side of the thermal insulation cotton 2 is installed with an insulation strip 3, and the outer frame 4 is provided with an external drainage hole 7 and an internal drainage hole 8 for drainage.
[0019] To be more specific, a middle rubber strip 5 for increasing the air tightness of the device is provided at the connection between the outer frame 4 and the hidden frame 1 .
[0020] More specifically, the outer frame 4 is provided with a water cavity A, and two adjacent walls of the water cavity A are respectively provided with an outer drainage hole 7 and an inner drainage hole 8. The rainwater can be discharged in time through the outer drainage hole 7 and the inner drainage hole 8 to avoid the accumulation of rainwater and affect the environmental sanitation.
[0021] More specifically, the outer drain hole 7 and the inner drain hole 8 are staggered. By staggering the outer drain hole 7 and the inner drain hole 8, it is possible to prevent rainwater from flowing back into the room from the outer drain hole 7 and the inner drain hole 8 due to air convection.
[0022] More specifically, between the hidden frame 1 and the outer frame 4, there are heat insulation strips 3, heat insulation cotton 2 and heat insulation strips 3 in sequence from outside to inside. By providing the heat insulation strips 3 and the heat insulation cotton 2, the heat insulation effect between the hidden frame 1 and the outer frame 4 can be ensured, and the heat between the indoor and outdoor can be better ensured not to be mutually conducted, which has a certain energy-saving and heat preservation effect.
[0023] More specifically, a lower rail 6 is installed on one side of the hidden frame 1. The lower rail 6 is a guide rail that is needed when assembling with hardware to facilitate hardware assembly.
[0024] Embodiment 2
[0025] See also Figure 3 As shown, the difference between this embodiment and the first embodiment is that a frame auxiliary material 9 is installed on one side of the hidden frame 1. The frame auxiliary material 9 is used to install the locking hardware and can also play a sealing role.
[0026] The working principle of the utility model is as follows: an outer drainage hole 7 and an inner drainage hole 8 are provided on two adjacent walls of the water cavity A on the outer frame 4 to ensure that the outer drainage hole 7 and the inner drainage hole 8 are distributed at 90 degrees, water will flow from the inner drainage hole 8 to the water cavity A, and be discharged to the outside through the outer drainage hole 7, so that drainage operation can be carried out in a timely and effective manner, and the outer drainage hole 7 and the inner drainage hole 8 are staggered openings. When drainage operation is carried out, the water can be smoothly discharged from the outer drainage hole 7 and the inner drainage hole 8, and when the external air flow rate is too fast, since the outer drainage hole 7 and the inner drainage hole 8 are staggered openings, the rainwater will not flow back into the room, thereby reducing the occurrence of water seepage in the room.
[0027] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
