Chinese Patent 202022357045.8 also disclosed a soundproof window profile structure, including an inner frame and an outer frame, characterized in that a plurality of sound insulation boards are provided between the inner frame and the outer frame, a glass frame is provided on the top left side of the inner frame, a screen frame is provided on the top right side of the outer frame, a first sound insulation strip is provided at the contact point between the inner frame and the glass frame, and a second sound insulation strip is provided at the contact point between the screen frame and the outer frame, a support base is fixed to the top of the inner frame and the outer frame, a support plate is fixed to the top of the support base, a third sound insulation strip is fixed to the left outer wall of the support plate, which contacts the inner and outer walls of the glass frame, and a fourth sound insulation strip is provided on the top of the support base, which contacts the inner and outer walls of the glass frame. The sound insulation strips and the glass frame in this patent both adopt contact and collision structures, and the heat insulation and sound insulation effects are not ideal. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a window frame structure with good sound insulation and heat insulation effects.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a window frame structure, including a window outer frame, a window sash and a rubber strip arranged on the window sash, characterized in that an insertion groove is provided on the window outer frame at the contact point with the rubber strip, an insertion strip matching the insertion groove is provided on the rubber strip, and a filling block is provided on the surface of the insertion strip in the gap between the window outer frame and the window sash.

[0005] Preferably, in the above-mentioned window frame structure, the insertion groove is U-shaped.

[0006] Preferably, in the above-mentioned window frame structure, the rubber strip, the insert strip and the filling block are integrally formed.

[0007] Preferably, in the above-mentioned window frame structure, a C-shaped groove is provided on the window sash, and the C-shaped groove is detachably connected to the rubber strip.

[0008] Preferably, in the above-mentioned window frame structure, both the upper and lower ends of the rubber strip are provided with protrusions matching the C-shaped groove.

[0009] Preferably, in the above-mentioned window frame structure, the protrusion and the rubber strip are integrally formed.

[0010] The technical effects of the present invention are mainly reflected in: after closing the window sash, the insertion strip will be directly inserted into the insertion groove, which is more sealed and silent than the contact structure in the prior art; a filling block is provided in the gap between the window frame and the window sash, which further enhances the sealing performance.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings and embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 、 2 As shown in Figures 3 and 4, a window frame structure includes a window outer frame 1, a window sash 2, and a rubber strip 3 provided on the window sash 2. The window sash 2 is provided with a C-shaped groove 11, and the C-shaped groove 11 is detachably connected to the rubber strip 3. To ensure a tight connection, the upper and lower ends of the rubber strip 3 are provided with protrusions 31 that match the C-shaped groove 11.

[0017] An insertion groove 10 is provided on the window outer frame 1 in the utility model at the contact point with the rubber strip 3. The insertion groove 10 is U-shaped. An insertion strip 41 matching the insertion groove 10 is provided on the rubber strip 3. A filling block 40 is provided on the surface of the insertion strip 41 in the gap between the window outer frame 1 and the window sash 2.

[0018] The rubber strip 3, the insert strip 41, the filling block 40 and the protrusion 31 in the present invention are all integrally formed. The purpose of such design is to improve production efficiency.

[0019] The technical effects of the present invention are mainly reflected in: after closing the window sash 2, the insertion strip 41 will be directly inserted into the insertion groove 10, which is more sealed and silent than the contact structure in the prior art; a filling block 40 is provided in the gap between the window frame 1 and the window sash 2, which further enhances the sealing performance.

[0020] It should be noted that the standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the utility model author will not elaborate here.

[0021] The above describes an embodiment of the present invention in detail. However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
