Description

Technical Field

[0001] This utility model relates to the technical field of sliding doors and windows, and in particular to a split-type lower track structure for sliding windows. Background Technology

[0002] Sliding windows are a common type of window, widely used due to their advantages such as not taking up indoor space, flexible opening, and low price. Traditional sliding windows consist of an outer frame and a sash. The sash is set in a track groove and slides horizontally on the guide rail in the track groove via sliding parts. To make the track profile waterproof, the inner side of the track groove is usually higher than the guide rail and the outer side of the track groove by a certain distance to form a certain height difference to prevent rainwater from seeping into the room. Drainage holes are set on the guide rail and the outer side of the track groove to drain rainwater from the track profile. However, such track profiles have insufficient drainage performance. In heavy rain, the drainage holes on the track profile are difficult to drain the water outside smoothly, which can easily cause rainwater in the track profile to backflow into the room. Now, in order to prevent rainwater backflow, the industry will raise the edge of the track profile and deepen the track groove to store more rainwater. However, this will cause rainwater to soak the sliding parts of the sash, and the excessively deep track groove is not conducive to cleaning and maintenance. Utility Model Content

[0003] The present invention provides a split-type lower rail structure for a sliding window to solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a split-type lower track structure for a sliding window, comprising a track profile and a mounting base. The track profile has a track groove. The mounting base has panels on both sides that abut against the groove wall of the track groove. A guide rail is provided on the top of the mounting base, thereby forming a water storage chamber between the mounting base and the track groove. The panels have a first drain hole communicating with the water storage chamber. A support plate is provided at the bottom of the mounting base. The support plate has a flat plate portion that abuts against the bottom of the track groove. A second drain hole is provided on the top of the flat plate portion. A drain outlet is provided at the lower part of the groove wall of the track profile.

[0005] Furthermore, several track profiles and mounting bases are provided, and thermal break adhesive is provided between adjacent track profiles.

[0006] Furthermore, the track profile includes two vertical plates and a base plate. The two vertical plates are symmetrically arranged on the top of the base plate, and the thermal break adhesive is disposed on one side of the base plate, thereby forming a water passage between the track profiles.

[0007] Furthermore, a cover plate is provided above the thermal break adhesive.

[0008] Furthermore, the inner side of the vertical plate is provided with a stepped structure that abuts against the panel.

[0009] Furthermore, the mounting base is a one-piece molded structure, and the top of the mounting base is provided with a mounting groove for mounting the guide rail.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The mounting seat is set in the track groove, which raises the guide rail and separates the guide rail from the water storage chamber under the mounting seat, so that rainwater will not soak the guide rail and the sliding parts. At the same time, the top of the water storage chamber is covered by the mounting seat, which makes the track groove shallower, which is conducive to cleaning and maintenance. Meanwhile, the flat plate provides support and the second drainage hole is set on the flat plate, which does not penetrate the bottom of the support plate, thereby preventing the mounting seat from deforming under the pressure of the sliding window sash and keeping the window sash sliding smoothly.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in the attached figure, this utility model discloses a split-type lower track structure for a sliding window, comprising a track profile 1 and a mounting base 2. The track profile 1 has a track groove 10. The mounting base 2 has panels 21 on both sides that abut against the groove wall of the track groove 10. A guide rail 23 is provided on the top of the mounting base 2, thereby forming a water storage chamber 100 between the mounting base 2 and the track groove 10. The panel 21 has a first drainage hole 211 communicating with the water storage chamber 100. A support plate 22 is provided at the bottom of the mounting base 2. The support plate 22 has a flat plate portion 222 abutting against the bottom of the track groove. A second drainage hole 212 is provided on the top of the flat plate portion 222. The flat plate portion 222 increases the contact area between the mounting base 2 and the track profile 1, improving support performance. By placing the second drainage hole 212 on the top of the flat plate portion 222, the mounting base 2 requires... To support the window sash, if the second drainage hole 212 is directly set at the bottom of the support plate 22, the weight of the window sash will deform the second drainage hole 212 on the mounting base 2. These slight deformations will reduce the smoothness of the window sash sliding. Therefore, setting the second drainage hole 212 at the top of the flat plate 222 can effectively avoid this situation and ensure that the window sash slides smoothly. The lower part of the groove wall of the track profile 1 is provided with a drainage outlet 110. It should be noted that in order to prevent rainwater from entering the room, if a single track profile 1 is set, the groove wall of the track profile 1 located on the indoor side is not provided with a drainage outlet 110. If multiple track profiles 1 are set, the groove wall of the track profile 1 close to the indoor side and facing the indoor side is not provided with a drainage outlet 110. The first drainage hole 211 and the second drainage hole 212 are set as multiple and arranged in the length direction of the mounting base 2.

[0020] This utility model discloses the principle and effect of a split-type lower track structure for a sliding window. An installation seat 2 is provided in the track groove 10. The installation seat 2 raises the guide rail 23, separating the guide rail 23 from the water storage chamber 100 under the installation seat 2, so that rainwater will not soak the guide rail 23 and the sliding parts. At the same time, the top of the water storage chamber 100 is covered by the installation seat 2, which makes the track groove 10 shallower, which is conducive to cleaning and maintenance. Most of the dust, sand and other impurities will be blocked outside the water storage chamber 100 by the installation seat 2. The distance between the installation seat 2 and the groove wall is not high, which is conducive to cleaning. A small amount of impurities will enter the water storage chamber 100 through the first drainage hole 211 and will be carried away by the rainwater. Furthermore, the track profile 1 and the mounting base 2 are separate structures, which facilitates the setting of drainage holes and drain outlets 110. Drain holes and drain outlets 110 can be set on the track profile 1 and the mounting base 2 respectively before the mounting base 2 is installed into the track groove 10, which is more conducive to production. Later, the mounting base 2 can be disassembled to clean the inside of the water storage chamber 100. If the guide rail 23 is damaged, the mounting base 2 can be removed and replaced separately. The mounting base 2 can be placed directly into the track groove 10. The inner side wall of the track profile 1 is provided with a protrusion for the panel 21 to overlap, and the panel 21 and the support plate 22 abut against the track. The profile 1 achieves a fixing effect, while the flat plate provides support to ensure that the mounting base 2 better supports the window sash. At the same time, the second drainage hole 212 is set on the flat plate 222, which means that it does not penetrate the bottom of the support plate 22, thereby preventing the mounting base 2 from deforming under the pressure of the sliding window sash and keeping the window sash sliding smoothly. If the second drainage hole 212 is set directly at the bottom of the support plate 22, that is, penetrating the bottom, a notch is formed at the bottom of the support plate 22. In this case, the notch is easy to deform under the pressure of the window sash for a long time, which will lead to the window sash not sliding smoothly.

[0021] Specifically, the track profile 1 and the mounting base 2 are provided in several forms, such as... Figure 4 The structure consists of two track profiles 1 and two mounting bases 2, with thermal break adhesive 3 installed between adjacent track profiles 1. This is a thermal break aluminum profile window / door structure, with the profile sections connected by the thermal break adhesive 3. The track profiles 1 and mounting bases 2 correspond one-to-one, and the number of track profiles 1 corresponds to the number of window sashes. Existing sliding windows typically have two or three sashes, but can also be configured with four or more sashes. (Specific details are as follows...) Figure 2-4As shown, the track profile 1 includes two vertical plates 11 and a base plate 12. The two vertical plates 11 are symmetrically arranged on the top of the base plate 12. The thermal break adhesive 3 is disposed on one side of the base plate 12, thereby forming a water passage 300 between the track profiles 1. The water passage 300 connects to the water storage chambers 100 inside the two adjacent track profiles 1, allowing rainwater from the track profiles 1 closer to the interior to flow through the water passage to the water storage chambers 100 on the exterior and be discharged outdoors. Furthermore, a cover plate 303 is provided above the thermal break adhesive 3 to cover the water passage. A U-shaped buckle is provided at the top of the water passage. The two sides of the U-shaped buckle overlap the outer sides of two adjacent groove walls on the adjacent track profiles 1. The cover plate 303 is snapped into the U-shaped buckle, which provides some support to prevent deformation of the two groove walls. Alternatively, the cover plate 303 can be directly snapped into the outer sides of two adjacent groove walls on the adjacent track profiles 1.

[0022] Specifically, the inner side of the vertical plate 11 is provided with a stepped structure 111 that abuts against the panel 21, which facilitates the installation of the mounting base 2. The mounting base 2 can be installed with the track profile 1 without the need for additional parts, and can also prevent the panel 21 from sinking and deforming. Together with the support plate 22, it can support the window sash. It can also be fixed with screws after the mounting base 2 is installed.

[0023] Specifically, the mounting base is an integrally molded structure, which includes a panel and a support plate, and the top of the mounting base is provided with a mounting groove for mounting guide rails.

[0024] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
