Description

Technical Field

[0001] This application relates to the field of door sealing technology, and in particular to a door under-door airtight strip sealing structure. Background Technology

[0002] Currently, bottom door seals are sealing materials installed at the bottom or underside of doors, primarily used to fill the gap between the door and the floor. They prevent wind, water, dust, insects, and other debris from entering the room, and also provide some sound insulation and heat preservation. Bottom door seals are typically made of rubber, silicone, or foam, possessing a certain degree of elasticity to conform well to the floor.

[0003] There is a gap between the door panel and the ground, allowing dust and water from outside to easily enter the door. Therefore, this gap needs to be sealed. Figure 5 In the existing technology, the sealing strip installation structure has one end clipped onto the door panel and the other end pressed against the ground. In use, the sealing strip seals the gap between the door panel and the ground.

[0004] Regarding the aforementioned technologies, the inventors believe that during the opening or closing of the door panel, the sealing strip will rub against the ground, causing wear on the sealing strip and thus reducing its sealing performance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a door bottom airtight strip sealing structure, which solves the technical problem that the sealing strip will rub against the ground during the opening or closing of the door panel, causing the sealing strip to wear and thus reducing the sealing performance of the sealing strip.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A door under-panel airtight sealing structure includes: a mounting bracket installed on the bottom of a door panel, the mounting bracket having a groove facing away from the door panel; a sealing strip, one side of which is installed on the mounting bracket and the other side extending towards the groove; and an ejection mechanism installed on the mounting bracket, the ejection mechanism ejecting the sealing strip from the groove.

[0008] With the above technical solution, the sealing strip is installed on the mounting frame. When the door panel is closed, the ejection mechanism pushes the sealing strip out from the groove of the mounting frame. The sealing strip seals the gap between the closed door panel and the ground. When the door panel is opened, the sealing strip retracts from the groove of the mounting frame, thereby reducing the friction between the sealing strip and the ground and improving the sealing performance of the sealing strip during use.

[0009] Furthermore, the mounting bracket is provided with a support plate, the support plate has a slot, and the sealing strip is provided with a retaining strip, which engages with the slot.

[0010] With the above technical solution, the sealing strip is snapped into the slot of the support plate by the clip, which improves the ease of installation of the sealing strip.

[0011] Furthermore, the ejection mechanism includes a positioning block and a pusher bar. The positioning block has a guide groove, which faces the side closest to the groove opening. One end of the pusher bar passes through the guide groove, and the end of the pusher bar passing through the guide groove is connected to the support plate.

[0012] The above technical solution pushes the pusher along the guide groove of the positioning block, so that the sealing strip can be pushed out from the groove of the mounting bracket.

[0013] Furthermore, the ejection mechanism includes a push rod, which is slidably mounted on the mounting bracket, and one end of the push bar is connected to the push rod.

[0014] With the above technical solution, one end of the pusher is installed on the fixed rod. During the push of the top rod, the pusher pushes out the sealing strip, which improves the convenience of pushing out the sealing strip.

[0015] Furthermore, a limit block is provided on the mounting bracket, and a support spring is sleeved on the top rod, with the support spring pressing against the top rod and the limit block.

[0016] With the above technical solution, the support spring is pressed between the limiting block and the top rod. When the top rod lifts the sealing strip, the support spring is in a compressed state. When the door panel is opened, the top rod retracts under the action of the support spring, which improves the convenience of the sealing strip's extension and retraction.

[0017] Furthermore, guide blocks are provided at both ends of the mounting bracket along its length, and one end of the top rod passes through the guide blocks in sequence.

[0018] Through the above technical solution, the guide block guides the top rod, thereby improving the stability of the top rod sliding on the mounting frame.

[0019] Furthermore, a pressure rod is provided at one end of the top rod, and a guide arc surface is formed at one end of the pressure rod, with the guide arc surface facing away from the mounting bracket.

[0020] Through the above technical solution, the guide arc surface at one end of the pressure rod contacts the door frame, which improves the convenience of pressing the top rod.

[0021] In summary, this application includes at least one of the following beneficial technical effects of the under-door airtight strip sealing structure:

[0022] 1. The sealing strip is installed on the mounting bracket. When the door panel is closed, the ejection mechanism pushes the sealing strip out of the groove of the mounting bracket. The sealing strip seals the gap between the closed door panel and the ground. When the door panel is opened, the sealing strip retracts from the groove of the mounting bracket, thereby reducing the friction between the sealing strip and the ground and improving the sealing performance of the sealing strip during use.

[0023] 2. The placement of the positioning block, push strip, and support plate improves the ease of extension and retraction of the sealing strip on the mounting bracket;

[0024] 3. The ease of movement of the top rod on the mounting frame is improved by using the limiting block, the supporting spring, and the pressure rod at one end of the top rod. Attached Figure Description

[0031] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a door under-door airtight strip sealing structure.

[0034] Reference Figures 1-3A door under-panel airtight sealing structure includes a mounting bracket 1, on which a sealing strip 2 and a push-out mechanism 3 are provided. The mounting bracket 1 is installed on the door panel. When the door panel is closed, the push-out mechanism 3 pushes out the sealing strip 2. When the door panel is opened, the push-out mechanism 3 retracts the sealing strip 2.

[0035] The mounting bracket 1 is generally long and narrow, and its cross-section is rectangular. A slot 11 is formed inside the mounting bracket 1, and the slot 11 is open on one side along the length of the cross-section of the mounting bracket 1.

[0036] Reference Figure 2 The mounting bracket 1 is provided with a support plate 12, which is rectangular in shape and parallel to the length of the mounting bracket 1. The support plate 12 is embedded in the slot 11 of the mounting bracket 1. The support plate 12 has two slots 121 spaced apart. The sealing strip 2 has a retaining strip 21, which is used to engage with the support plate 12. In use, the corresponding support plate 12 and sealing strip 2 can be selected according to the length of the lower part of the door panel. The support plate 12 can improve the overall structural strength of the sealing strip 2.

[0037] Reference Figure 3 The ejection mechanism 3 includes positioning blocks 31. Two positioning blocks 31 are spaced apart on the mounting frame 1, and the two positioning blocks 31 are mounted on the mounting frame 1. The positioning blocks 31 are provided with guide grooves 32. The guide grooves 32 are arc-shaped and face the side closer to the slot opening 11.

[0038] Reference Figure 4 The positioning block 31 is provided with a pusher 33, which is made of flexible plastic. One end of the pusher 33 passes through the guide groove 32 on the positioning block 31, and the end of the pusher 33 passing through the positioning block 31 is connected to the support plate 12. In use, the pusher 33 is moved, and the pusher 33 pushes the support plate 12 towards the side closer to the groove 11 along the guide groove 32 of the positioning block 31.

[0039] To improve the ease with which the push bar 33 pushes the support plate 12, the ejection mechanism 3 includes a push rod 34. The push rod 34 is generally round, and its axis is parallel to the length direction of the mounting frame 1. The push bar 33 is mounted on the push rod 34. When the door panel is closed, one end of the push rod 34 abuts against the door frame. At this time, the push rod 34 pushes the push bar 33 along the length direction of the mounting frame 1, and the push bar 33 pushes the support plate 12 and the sealing strip 2 towards the side closer to the groove 11.

[0040] Reference Figure 3When the door panel is opened, the sealing strip 2 needs to retract into the mounting bracket 1. To improve the ease of retraction, the mounting bracket 1 is equipped with limit blocks 35, with two limit blocks 35 spaced apart. One end of the push rod 34 passes through the two limit blocks 35 in sequence. A fixing block 36 is provided on the side of the push rod 34 near the corresponding limit block 35, and the fixing block 36 is connected to the fixed rod. A support spring 37 is provided between the fixing block 36 and the limit block 35. The support spring 37 is sleeved on the push rod 34, and both ends of the support spring 37 abut against the fixing block 36 and the limit block 35 respectively. When the push rod 34 lifts the sealing strip 2, the support spring 37 is in a compressed state. When the door panel is open, the push rod 34 descends under the action of the support spring 37, and the fixing block 36 moves away from the limit block 35, causing the sealing strip 2 to retract into the mounting bracket 1.

[0041] To improve the stability of the push rod 34 moving on the mounting frame 1, guide blocks 13 are installed on the mounting frame 1. Two guide blocks 13 are spaced apart on the mounting frame 1, and the two ends of the push rod 34 pass through the guide blocks 13 on both sides respectively. In use, the guide blocks 13 guide the push rod 34, thereby improving the stability of the push rod 34 moving on the mounting frame 1.

[0042] When the door panel is closed, to reduce friction between the top rod 34 and the door frame, a pressure rod 341 is provided at one end of the top rod 34, and a guide arc surface 342 is formed at one end of the pressure rod 341. In use, the guide arc surface 342 of one end of the pressure rod 341 contacts the door frame. When the door panel is closed, one end of the pressure rod 341 abuts against the door frame. As the gap between the door panel and the door frame decreases, the top rod 34 pushes the sealing strip 2 out of the groove 11 through the push strip 33. At this time, the support spring 37 is in a compressed state. When the door panel is opened, the top rod 34 extends out of the mounting bracket 1 under the action of the support spring 37. At this time, the sealing strip 2 retracts into the mounting bracket 1 under the action of the push strip 33, thereby reducing the friction between the sealing strip 2 and the ground when the door panel is opened.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
