Technical Field

[0001] The utility model belongs to the technical field of sliding windows, and particularly relates to a horizontal sliding window, specifically to a bottom frame of a sliding window, and also relates to a sliding window. Background Art

[0002] Sliding windows are divided into two types: horizontal sliding windows and vertical sliding windows according to different sliding directions. Horizontal sliding windows need to be provided with rail grooves above and below the window sashes, and vertical sliding windows require pulleys and balancing measures. The sliding window uses a window sash equipped with pulleys to slide on the track of the window frame. The advantage of this kind of window is that it does not occupy extra space whether it is in the open or closed state, and the structure is relatively simple.

[0003] In the prior art, the bottom frame of a sliding window is usually a "mouth"-shaped structural combination composed of two side frames and two upper and lower sliding rails (hereinafter, the side frames and the sliding rails are collectively referred to as the frame). There are usually three processes for the combination (corner assembly) between the four side frames of the sliding window, namely the movable corner code process, the impact angle process, and the injection molding process.

[0004] Among the above three corner assembly processes, the movable corner code process is the simplest, and it can be assembled on-site, and at the same time has the characteristics of convenient disassembly and assembly. However, its stability and sealing performance are poor. Although the impact angle process and the injection molding process have high stability and sealing performance, they cannot be assembled on-site, and there are great restrictions on the construction site during installation.

[0005] To solve the above problems, a bottom frame of a sliding window and a sliding window are proposed in this application. While ensuring stability and sealing performance, it can be assembled on-site, is less restricted by the construction site, and meets the requirements of different installation environments.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A bottom frame of a sliding window, including a bottom frame main body 1 formed by connecting four side frames 11 end to end. Both ends of the side frame 11 are processed into inclined surfaces at 45 degrees. There is a guide rail 111 on the side frame 11. It also includes: a protective sheet 12, a right-angle corner fitting 13, and a rubber sealing sheet 3.

[0036] Furthermore, as shown by Figures 1-3 , in this embodiment, the protective sheet 12 is fixed to the outer wall of the side frame 11 by a first fixing member. An insertion opening 114 for the right-angle corner fitting 13 to be inserted is processed at the end of the outer side surface of the side frame 11. The protective sheet 12 is fixedly connected to the right-angle corner fitting 13 by a second fixing member. The rubber sealing sheet 3 is fixed between the outer wall of the right-angle corner fitting 13 and the inner wall of the insertion opening 114. After adopting the above solution, during frame assembly, first fix the rubber sealing sheet 3 on the right-angle corner fitting 13, then insert both ends of the right-angle corner fitting 13 into the insertion openings 114 at the ends of two different side frames 11 respectively, and make the inclined surfaces at the ends of the side frames 11 fit together. After the four side frames 11 are pre-connected and framed by the right-angle corner fitting 13, sequentially fix the four protective sheets 12 to the outer wall of the side frame 11 by the first fixing member, and fixedly connect the protective sheet 12 to the right-angle corner fitting 13 by the second fixing member. Thus, the framing of the bottom frame main body 1 is completed. The rubber sealing sheet 3 is squeezed to ensure the sealing performance of the bottom frame main body 1. The bottom frame main body 1 of the present utility model not only supports framing during processing but also supports on-site framing, is less restricted by the construction site, meets the requirements of different installation environments, and can also ensure the stability and sealing performance after framing.

[0037] It should be noted that during actual use, the insertion opening 114 can be processed on the inclined surface at the end of the side frame 11 or at the node position between the outer side surface and the inclined surface of the side frame 11. The two methods only differ in the process steps of frame assembly, and the difference in stability after frame assembly is not significant. For example, if the insertion opening 114 is processed on the inclined surface at the end of the side frame 11, during frame assembly, because the end of the side frame 11 is an inclined surface, one end of the right-angle corner fitting 13 must be inserted into the insertion opening 114 at the end of one side frame 11 first, and then the other end is inserted into the insertion opening 114 at the end of another side frame 11, and so on; if the insertion opening 114 is processed at the node position between the outer side surface and the inclined surface of the side frame 11, the insertion opening 114 is an open structure. The four side frames 11 can be pre-connected and framed first, and then the right-angle corner fitting 13 is inserted into the insertion opening 114. Both ends of the right-angle corner fitting 13 can be inserted into the insertion openings 114 at the ends of two adjacent side frames 11 simultaneously.

[0038] Preferably, as shown by Figure 1As shown, in this embodiment, a diversion hole 112 is processed on the bottom border 11. It is only necessary to process the diversion hole 112 on one border 11. During use, this border 11 serves as a lower slide rail. When rainwater drips onto the border 11, it will be discharged from the diversion hole 112 to prevent rainwater from accumulating in the border 11 for a long time.

[0039] Preferably, Figures 1-3 As shown, in this embodiment, both ends of the protective sheet 12 are processed into inclined surfaces at 45 degrees and coincide with the inclined surfaces at both ends of the border 11. Therefore, when the four protective sheets 12 are fixedly assembled, the four protective sheets 12 will also be connected into a tight frame. And with this design, adjacent two protective sheets 12 can restrict each other to prevent the protective sheet 12 from generating lateral slippage.

[0040] It should be noted that during actual use, in addition to the above inclined surface design, other designs with similar functions can also be adopted at both ends of the protective sheet 12, such as mutually staggered wavy surfaces, where the wave crests and wave troughs mesh with each other, which also has a similar restricting effect.

[0041] Optionally, Figure 1 and Figure 2 As shown, in this embodiment, the first fixing member includes: a No. 1 countersunk head screw 2. There is a No. 1 countersunk hole 121 on the protective sheet 12 and a No. 1 internal threaded hole 113 on the border 11. After the No. 1 countersunk head screw 2 passes through the No. 1 countersunk hole 121, it is screwed into the No. 1 internal threaded hole 113 by a thread engagement method. After adopting the above solution, the protective sheet 12 is fixedly connected to the border 11 by the No. 1 countersunk head screw 2, which not only provides safety protection for the border 11, but also the protective sheet 12 is used to limit the right-angle corner code 13 and restrict the right-angle corner code 13 at the corner position of the bottom frame body 1.

[0042] It should be noted that the above solution, as a preferred technical solution of the present invention, does not limit the present invention. During actual use, other means can also be used to fix the protective sheet 12, such as fixing with rivets or fixing with glue. As a preferred implementation, the No. 1 countersunk head screw 2 is used to fix the protective sheet 12, which is not only more convenient for fixing while ensuring stability, but also has the characteristic of being easy to disassemble.

[0043] Optionally, Figures 1-3As shown in the figure, in this embodiment, the second fixing member includes: a No. 2 countersunk head screw 4. There is a No. 2 counterbore 122 on the protective sheet 12 and a No. 2 internal threaded hole 131 on the right-angle corner bracket 13. The No. 2 countersunk head screw 4 passes through the No. 2 counterbore 122 and is screwed into the No. 2 internal threaded hole 131 by means of thread engagement. After adopting the above solution, the protective sheet 12 is fixedly connected to the right-angle corner bracket 13 by the No. 2 countersunk head screw 4, further ensuring the stability and sealing performance of the assembly of the frame 11, the protective sheet 12 and the right-angle corner bracket 13, and ensuring the stability and sealing performance of the bottom frame body 1.

[0044] It should be noted that the above solution, as the preferred technical solution of the present utility model, does not limit the present utility model. In actual use, other means can also be used to fixedly connect the protective sheet 12 and the right-angle corner bracket 13, such as fixing with rivets or bonding with glue. As a preferred implementation, the No. 2 countersunk head screw 4 is used to fix the protective sheet 12 and the right-angle corner bracket 13. While ensuring stability, the fixing is more convenient and it also has the characteristic of being easy to disassemble.

[0045] Preferably, from Figures 1-3 As shown in the figure, in this embodiment, when the right-angle corner bracket 13 is completely embedded in the socket 114, the outer wall of the right-angle corner bracket 13 coincides with the outer wall of the frame 11. In fact, as long as the outer wall of the right-angle corner bracket 13 does not protrude outward from the outer wall of the frame 11, it is preferably in a coincident state. When the protective sheet 12 is fixedly assembled, the protective sheet 12 will simultaneously fit the outer walls of the frame 11 and the right-angle corner bracket 13, ensuring stability and avoiding bending of the protective sheet 12 after being locked.

[0046] Preferably, from Figures 1-4 As shown in the figure, in this embodiment, it further includes: an elastic sheet 124. There is a T-shaped slot 132 on the outer wall of the right-angle corner bracket 13. The elastic sheet 124 is fixed to the outer wall of the protective sheet 12. The elastic sheet 124 is embedded in the T-shaped slot 132, and a block 125 adapted to the T-shaped slot 132 is fixed at the end of the elastic sheet 124. After adopting the above design, when assembling the protective sheet 12, the elastic sheet 124 and the block 125 are snapped into the T-shaped slot 132, which can not only accurately position the installation position of the protective sheet 12, but also further improve the connection stability between the protective sheet 12 and the right-angle corner bracket 13.

[0047] Preferably, from Figures 1-4As shown, in this embodiment, the clamping block 125 is a semi-cylindrical component, and an inclined chamfer 133 is machined at the port of the T-shaped card slot 132. The above design has a guiding function. When assembling the protective sheet 12, the clamping block 125 and the elastic sheet 124 are inserted into the T-shaped card slot 132. During this process, after the clamping block 125 presses against the inclined chamfer 133, a component force is generated, prompting the elastic sheet 124 to bend inward until the clamping block 125 and the elastic sheet 124 are completely inserted into the T-shaped card slot 132. At this time, the elastic sheet 124 returns to its original state and forms a clamping fit with the T-shaped card slot 132.

[0048] Preferably, Figures 1-3 As shown, in this embodiment, glue injection ports 123 are machined at both ends of the protective sheet 12, and the glue injection ports 123 penetrate through the two opposite side surfaces of the protective sheet 12. With this design, after the bottom frame body 1 is assembled into a frame, glue can be injected through the glue injection ports 123. The glue reaches the right-angle corner fitting 13 along the glue injection ports 123, bonding the right-angle corner fitting 13 and the protective sheet 12, which can further improve stability and sealing performance.

[0049] A sliding window includes the sliding window bottom frame described in the above specific embodiment, and further includes: a window sash 5, Figures 1-5 As shown, at least two window sashes 5 are slidably assembled in the bottom frame body 1. In the figure, two window sashes 5 are shown slidably assembled in the bottom frame body 1. In fact, the window sash 5 has a groove that matches the guide rail 111, and the guide rail 111 is embedded in the groove to form a sliding structure. The sliding principle of the window sash 5 is prior art that has been fully disclosed for sliding windows and will not be elaborated here.

[0050] Components not described in detail herein are prior art.

[0051] The working principle and usage process of the present utility model: For the sliding window bottom frame and the sliding window of the present utility model, when assembling the frame, first fix the rubber sealing sheet 3 on the right-angle corner fitting 13, and conventional means such as glue bonding can be used to fix the rubber sealing sheet 3;

[0052] After that, insert the two ends of the right-angle corner fitting 13 into the sockets 114 at the ends of two different side frames 11 respectively, and make the inclined surfaces at the ends of the side frames 11 fit together. After the four side frames 11 are pre-connected and assembled into a frame through the right-angle corner fitting 13, fix the four protective sheets 12 on the outer wall of the side frames 11 using the first fixing member in sequence, and fix the protective sheets 12 to the right-angle corner fitting 13 using the second fixing member. Thus, the assembly of the bottom frame body 1 is completed, and the rubber sealing sheet 3 is pressed to ensure the sealing performance of the bottom frame body 1;

[0053] The bottom frame body 1 of the present utility model not only supports frame assembly during processing but also supports on-site frame assembly. It is less restricted by the construction site, meets the requirements of different installation environments, and can also ensure the stability and sealing performance after frame assembly;

[0054] In addition, a glue injection port 123 is reserved on the protective sheet 12 of the present utility model. With this design, after the bottom frame main body 1 is assembled into a frame, glue can be injected through the glue injection port 123. The glue reaches the right-angle corner code 13 along the glue injection port 123, bonding the right-angle corner code 13 and the protective sheet 12, which can further improve the stability and sealing performance.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
