Detailed Implementation Modes

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0026] As Figures 1-8 shown, the heat-insulating and sound-insulating lifting sliding door includes an upper door slide 1 and a lower door slide 2 which are arranged opposite to each other. Between the upper door slide 1 and the lower door slide 2, there is a door edge seal 3. Between the upper door slide 1 and the lower door slide 2, there are parallel door leaves 4. Inside the door leaves 4, there is a push-pull hardware. On the door leaves 4, there is a first rubber strip 9 which is arranged opposite to the upper door slide 1 and the lower door slide 2. On one side of the door leaf 4 opposite to the door edge seal 3, there is a second rubber strip 10. On the parallel door leaves 4, there are third rubber strips 11 respectively. Specifically, there are two door edge seals 3. The two door edge seals 3 are arranged vertically. The upper sides of the two door edge seals 3 are connected by the upper door slide 1, and the lower sides of the two door edge seals 3 are connected by the lower door slide 2. The window frame formed by the two door edge seals 3, the upper door slide 1 and the lower door slide 2 is rectangular. Between the upper door slide 1 and the lower door slide 2, there are two door leaves 4, and the lower ends of the door leaves 4 rest on the lower door slide 2, and the door leaves 4 are connected to the upper door slide. The push-pull hardware is a prior art. By turning the handle on the push-pull hardware, the push-pull hardware drives the entire door leaf 4 to move upward, thereby facilitating the horizontal movement of the door leaf 4.

[0027] When in use, when the two door leaves 4 are in a closed state, the first rubber strip 9 on the upper side of the door leaf 4 abuts against the upper door slide 1, and the first rubber strip 9 on the lower side of the door leaf 4 abuts against the lower door slide 1. The second rubber strip 10 on the side end of the door leaf 4 abuts against the door edge seal 3. The third rubber strip 4 on the door leaf 4 abuts against another door leaf 4. Thus, with the cooperation of the first rubber strip 9, the second rubber strip 10 and the third rubber strip 11, the sound insulation effect and heat insulation performance of the door leaf 4 are enhanced, and the practicability is higher. By turning the handle on the push-pull hardware, the door leaf 4 moves upward, and thus the first rubber strips 9 on the upper and lower sides of the door leaf 4 are separated from the upper door slide 1 and the lower door slide 2, thereby realizing the convenient movement of the door leaf 4.

[0028] Referring to Figure 5 and 6, the door leaf 4 is snap-connected to the first rubber strip 9. The first rubber strip 9 is provided with a first overlapping protrusion 14. The upper door slide 1 and the lower door slide 2 are provided with a first overlapping inclined surface 15 that cooperates with the first overlapping protrusion 14. When the door leaf 4 is in a static state, the first overlapping protrusion 14 abuts against the first overlapping inclined surface 15, thereby ensuring better sealing performance of the first rubber strip 9. In this embodiment, two protruding guide posts are respectively provided on the upper door slide 1 and the lower door slide 2, and the two protruding guide posts respectively abut against the first rubber strips 9 on the two door leaves 4. Two card slots are symmetrically provided at the upper end of the door leaf 4, and the first rubber strips 9 are respectively snap-connected in the two card slots. The first overlapping inclined surface 15 is provided on the protruding guide post.

[0029] Refer to Figures 1-4 , edge-sealing splicing pipes 8 are provided on both sides of the door leaf 4. The second rubber strip 10 is snap-connected to the door leaf 4. The second rubber strip 10 is provided with a contact block 16 disposed opposite to the door edge seal 3. The second rubber strip 10 is provided with a second overlapping protrusion 17. The edge-sealing splicing pipe 8 is provided with a second overlapping inclined surface 18 that cooperates with the second overlapping protrusion 17. When the door leaf 4 is closed, the first contact block 16 on the second rubber strip 10 abuts against the door edge seal 3, so that the first rubber strip 10 can stably perform sound insulation and heat insulation work. Thus, the second overlapping protrusion 17 on the second rubber strip 10 abuts against the second overlapping inclined surface 18 on the edge-sealing splicing pipe 8, thereby preventing sound and heat from flowing out of the gap between the edge-sealing splicing pipe 8 and the door leaf 4. In this embodiment, a groove is provided on the contact block 16, and a protrusion that cooperates with the groove is provided on the door edge seal 3. In addition, two card slots are respectively provided on the left and right sides of the door leaf 4, so as to ensure that the second rubber strips 10 in the two card slots on one side of the door leaf 4 stably abut against the edge-sealing splicing pipe 8, realizing the sealing and heat insulation work.

[0030] Refer to Figure 3 , a lifting cover plate 7 is provided on the door leaf 4. The lifting cover plate 7 is snap-connected to the third rubber strip 11. The lifting cover plate 7 is disposed on one side of the door leaf 4 opposite to the edge-sealing splicing pipe 8. The lifting cover plate 7 is snap-connected to the door leaf 4, and the cross section of the lifting cover plate 7 is L-shaped. Thus, one side of the lifting cover plate 7 closes the door leaf 4, and the other side of the lifting cover plate 7 is used for snap-connecting with the third rubber strip 11. In this embodiment, a card slot for snap-connecting with the third rubber strip 11 is provided on the lifting cover plate 7, and a long strip is further provided on the lifting cover plate 7 for abutting against the third rubber strip 11 on the lifting cover plate 7 of another door leaf 4, thereby realizing the buffering work when the door leaf 4 is closed. In addition, the third rubber strips 11 on the two door leaves 4 further realize the sealing work between the two door leaves 4, and the sealing effect is better.

[0031] A wool strip 12 is provided on the lifting cover plate 7 to increase the sealing performance of the sliding door. In this embodiment, a card slot is provided on the lifting cover plate 7, and the wool strip 12 is snap-connected in the card slot. The wool strip 12 on one door leaf 4 contacts another door leaf 4.

[0032] A spacer 13 is provided between the lifting cover plate 7 and the door leaf 4. The sealing performance between the lifting cover plate 7 and the door leaf 4 is enhanced through the spacer 13. In this embodiment, the cross-section of the spacer 13 is L-shaped, and the spacer 13 is a PVC spacer.

[0033] The door leaf 4 is connected to the glass through a pressing strip 5. An installation rubber strip is installed on the door leaf 4. The glass is placed inside the door leaf 4. The pressing strip 5 is snap-connected to the door leaf 4, and then the pressing strip 5 presses another installation rubber strip to abut against the glass, thereby realizing the installation of the glass on the door leaf 4.

[0034] A lower sliding cover plate 6 is provided on the lower door slide 2. A stainless-steel track 19 in contact with the pulley of the push-pull hardware is provided on the lower sliding cover plate 6. The contact friction with the pulley is further reduced through the stainless-steel track 19, thereby facilitating the sliding of the door leaf 4 between the upper door slide 1 and the lower door slide 2, and further increasing the mobility convenience of the door leaf 4.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
