Description

Technical Field

[0001] The utility model relates to the field of door and window profiles, in particular to a lower rail profile of a sliding window. Background Art

[0002] At present, in the lower rail profile of the sliding frame, wool strips or rubber strips are generally set on the fan profile to increase the water tightness of the window. However, in the frame profile, wool strips or rubber strips are generally installed on both sides of the frame profile. When the fan is pushed and pulled, there is no corresponding structure between the fans, the water tightness and sound insulation effect of the fan are poor, and the fans are prone to collision. However, directly designing a corresponding structure on the frame profile fan is not convenient for the installation of the fan.

[0003] CN201720266488.1 discloses a thermally-broken bridge profile, a window frame and a window. The thermally-broken bridge profile includes a first profile and a second profile, which are connected by a barrier. The first profile includes a first base and a first slide rail, and the second profile includes a second base and a second slide rail. The first slide rail and the first base, and the second slide rail and the second base are all detachably connected. Therefore, the first base and the second base can be produced separately by casting, and the first slide rail and the second slide rail can be finely machined by a machine tool. The first slide rail and the second slide rail can provide a sliding surface with very small roughness for the window lattice; thus, the window lattice makes less noise during the pushing and pulling process. There is no structure for fixing corresponding rubber strips or wool strips between the slide rails of the thermally-broken bridge profile.

[0004] The technical problem to be solved by the utility model is: how to increase the water tightness and sound insulation effect of the profile and facilitate the installation of the entire window. Utility Model Content

[0005] The main purpose of the utility model is to provide a lower rail profile of a sliding window, wherein a first groove is provided on the profile body, a detachable barrier is placed on the first groove, a rubber strip or a wool strip is installed on the barrier, the barrier can separate the sashes to prevent mutual interference, and the rubber strip or the wool strip can increase the sealing and sound insulation effect of the window after the sashes are installed. Secondly, the barrier is installed in a detachable manner, which is also convenient for the staff to disassemble and assemble.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] A lower rail profile for a sliding window comprises a profile body and a barrier; the profile body is provided with a plurality of slide rails, and a first groove is provided between adjacent slide rails; the barrier is overlapped on the first groove in a detachable manner; the barrier is provided with a first installation groove for installing a rubber strip or a wool strip.

[0008] Preferably, first lap plates are provided on both sides of the first groove; symmetrically arranged elastic arms are provided at the bottom of the barrier; and guide slopes and non-return surfaces are provided at the free ends of the elastic arms.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Example 1

[0022] refer to Figure 1-2 A lower rail profile of a sliding window includes a profile body 1 and a barrier member 2; the profile body 1 is provided with a plurality of slide rails 11, and a first groove 12 is provided between adjacent slide rails 11; the barrier member 2 is overlapped on the first groove 12 in a detachable manner; the barrier member 2 is provided with a first installation groove 21 for installing a rubber strip or a wool strip.

[0023] In this embodiment, the number of slide rails 11 is 3, and different numbers of slide rails 11 can also be set according to actual conditions. The slide rails 11 are arranged on the upper surface of the profile body 1; a first groove 12 is arranged between adjacent slide rails 11, and the barrier is installed on the first groove 12 by bolts or bayonet. The staff overlaps the external fan profile on the slide rail 11, and the staff can fill the first groove 12 with sound insulation cotton or foaming agent to increase the sound insulation effect and water tightness of the whole window. After installing an external fan profile, the staff installs the rubber strip or wool strip in the first installation groove 21, and then installs the barrier on the first groove 12. By arranging the rubber strip or wool strip on the barrier, the adjacent external fan profiles are in contact with the rubber strip or wool strip, thereby improving the water tightness and sound insulation effect of the whole window.

[0024] By providing a detachable barrier, the space in the first groove 12 can be further utilized, and a foaming agent or sound insulation cotton can be filled, or when the entire window is an electric window, the wires can be placed in the first groove 12, which is convenient for the staff to wire. Secondly, by providing a detachable barrier, when the height or size of the first installation groove 21 needs to be changed, only the barrier needs to be replaced without replacing the entire profile, which reduces costs. The detachable manner also makes it easier for the staff to install the entire window.

[0025] Preferably, first lap plates 13 are provided on both sides of the first groove 12 ; symmetrically arranged elastic arms 22 are provided at the bottom of the barrier 2 ; and guide slopes 23 and non-return surfaces 24 are provided at the free ends of the elastic arms 22 .

[0026] In this embodiment, the engagement process of the barrier member is as follows: the staff places the barrier member on the first groove 12 and presses downward, the guide slope 23 of the elastic arm 22 contacts the first lap plate 13, and when the elastic arm 22 is deformed and moves downward under the force, the first lap plate 13 first contacts the guide slope 23, so that the elastic arm 22 enters the opening formed by the two first lap plates 13 until the barrier member is overlapped on the first lap plate 13, at this time, the non-return surface 24 contacts the ground of the first lap plate 13; when the barrier member needs to be removed, the staff only needs to lift the gap of the barrier member to make the non-return surface 24 separate from the first lap plate 13, and the barrier member can be separated from the first groove 12, thereby realizing the detachable connection between the first groove 12 and the barrier member.

[0027] Preferably, a support plate 25 is provided on the upper surface of the barrier 2 ; and the first mounting grooves 21 are respectively connected to two sides of the support plate 25 .

[0028] In this embodiment, the staff installs the rubber strip or wool strip on the first installation groove 21, and sets the height of the support plate 25 according to actual needs, so that the rubber strip or wool strip is located at a suitable position of the external fan profile.

[0029] Preferably, the profile body 1 is provided with a mounting hole 14 for connecting with an external profile; and the bottom of the profile body 1 is provided with a second mounting groove 15 for connecting with a wall.

[0030] In this embodiment, the mounting holes 14 are connected to the two side frame profiles of the peripheral device, and the profile body 1 is connected to the wall by filling cement or foaming agent in the second mounting groove 15. The second mounting groove 15 is surrounded by extension plates extending downward from both sides of the bottom of the profile body 1.

[0031] Preferably, a first baffle 16 and a second baffle 17 are respectively provided on both sides of the profile body 1 ; the height of the free end of the first baffle 16 is greater than the height of the free end of the second baffle 17 .

[0032] In this embodiment, the first baffle 16 is located on one side of the room, and the second baffle 17 is located on one side of the room. The height of the free end of the first baffle 16 is set to be greater than the height of the free end of the second baffle 17. Since the first baffle 16 is higher than the second baffle 17, when rainwater enters the profile body 1, the rainwater will first overflow the second baffle 17, thereby preventing rainwater from entering the room.

[0033] Preferably, the second baffle plate 17 and the slide rail 11 close to the second baffle plate 17 form a second groove 18 ; second lap plates 19 are provided on both sides of the second groove 18 .

[0034] In this embodiment, the second groove 18 is a cavity with an opening. When there is rain, the rain can enter the second groove 18, so that the rain can flow into the second groove 18 as much as possible, and then be discharged through the drainage holes on the second baffle plate 17, so as to prevent the rain from flowing into the room from the slide rail 11 when the rainfall is heavy. When used as an indoor window, the second groove 18 can be filled with sound insulation cotton, or, when the window is an electric window, an electric wire is placed, and then the external cover plate is overlapped on the second overlap plate 19.

[0035] Preferably, the bottom of the first groove 12 and the bottom of the second groove 18 form a plane inclined downward in a direction close to the second baffle 17 .

[0036] In this embodiment, the first groove 12 and the second groove 18 are gradually inclined downward, and when it rains, rainwater on the profile body 1 can flow outdoors along the inclined surface.

[0037] Preferably, the bottom of the profile body 1 gradually slopes upward along a direction approaching the second baffle 17 .

[0038] In this embodiment, since the side close to the outdoors needs to resist external wind and rain, the side of the profile close to the outdoors is subjected to greater force than the side close to the indoors. The bottom of the profile body 1 is arranged to gradually tilt upward along the direction close to the second baffle 17. The side of the profile body 1 close to the outdoors can be filled with more foaming agent or cement to increase its bearing capacity, while the side close to the indoors only requires relatively less foaming agent or cement, thereby reducing construction costs.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
