Description

Technical Field

[0001] The utility model relates to the technical field of window sealing strips, in particular to a silicone sealing strip. Background Art

[0002] The window is composed of parts such as a movable window frame and a fixed window frame, and there is a gap between the movable window frame and the fixed window frame. In order to avoid air leakage in the gap between the two, a silicone sealing strip will be installed in the gap between the movable window frame and the fixed window frame.

[0003] Since silicone sealing strips will be damaged after long-term use, in order to better seal between the two, the silicone sealing strips will be replaced regularly.

[0004] However, the existing silicone sealing strip is designed as an integral whole, so that when the silicone sealing strip is damaged, it needs to be replaced as a whole, which leads to a relatively large waste, and the overall processing and manufacturing cost of the silicone sealing strip is also high.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original silicone sealing strip. Utility Model Content

[0006] The utility model aims to provide a silicone sealing strip to solve the problems of the silicone sealing strip mentioned in the background art.

[0007] To achieve the above object, the utility model provides the following technical solutions: a silicone sealing strip, comprising a movable window frame, a card slot is provided at an edge of one side of the movable window frame, a plastic plate is installed inside the card slot, a silicone strip is attached to the outer side of the movable window frame, a docking groove is provided on one side of the silicone strip, and one side of the plastic plate passes through the inside of the card slot and is located inside the docking groove;

[0008] An inner cavity is provided inside the silicone strip, a first supporting component is fixed inside the inner cavity, and a second supporting component is fixed inside the first supporting component;

[0009] The outer side of the silicone strip is provided with protrusions, and the protrusions are evenly distributed on the outer side of the silicone strip.

[0010] Preferably, one side of the plastic plate is designed as a "T"-shaped structure, and one side of the plastic plate is snap-connected to the slot.

[0011] Preferably, the other side of the plastic plate is designed as a "T"-shaped structure, and the other side of the plastic plate is snap-connected to the docking groove.

[0012] Preferably, the first supporting component is made of silicone and is designed to be a circular tubular structure.

[0013] Preferably, the second supporting component is made of silicone, and the end of the second supporting component is designed to be a "cross" structure.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the silicone sealing strip is composed of a silicone strip and a plastic plate, and the silicone strip and the plastic plate are connected by snapping, which ensures that a new silicone strip can be replaced after the silicone strip is damaged, avoiding the replacement of the plastic plate and the silicone strip as a whole, and reducing waste;

[0015] The first supporting component and the second supporting component are both made of silicone, and the first supporting component is designed to be a circular tubular structure, and the end of the second supporting component is designed to be a "cross" structure. Under the action of the first supporting component and the second supporting component, the silicone strip is restored, ensuring that the silicone strip can be restored after being flattened, which is beneficial to the sealing of the silicone strip to the connection between the window frame and the fixed window frame, and prolongs the service life of the silicone strip.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a silicone sealing strip, comprising a movable window frame 1, a card slot 2 is provided at the edge of one side of the movable window frame 1, a plastic plate 3 is installed inside the card slot 2, a silicone strip 4 is attached to the outer side of the movable window frame 1, a docking groove 5 is provided on one side of the silicone strip 4, and one side of the plastic plate 3 passes through the inside of the card slot 2 and is located inside the docking groove 5;

[0022] An inner cavity 6 is formed inside the silicone strip 4, a first supporting component 7 is fixed inside the inner cavity 6, and a second supporting component 8 is fixed inside the first supporting component 7;

[0023] The outer side of the silicone strip 4 is provided with protrusions 9 , and the protrusions 9 are distributed at equal intervals on the outer side of the silicone strip 4 .

[0024] One side of the plastic plate 3 is designed as a “T”-shaped structure, and one side of the plastic plate 3 is snap-connected with the card slot 2 , so that the plastic plate 3 can be removed from the inside of the card slot 2 and replaced.

[0025] The other side of the plastic plate 3 is designed as a "T"-shaped structure, and the other side of the plastic plate 3 is snap-connected to the docking groove 5, so that the plastic plate 3 and the silicone strip 4 can be disassembled, ensuring that a new silicone strip 4 can be replaced after the silicone strip 4 is damaged, avoiding the overall replacement of the plastic plate 3 and the silicone strip 4 and reducing waste.

[0026] The material of the first supporting component 7 is silicone, and the first supporting component 7 is designed to be a circular tubular structure. The design of the first supporting component 7 is conducive to the recovery of the silicone strip 4 after deformation, thereby extending the service life of the silicone strip 4.

[0027] The material of the second supporting component 8 is silicone, and the end of the second supporting component 8 is designed to be a "cross" structure. The design of the second supporting component 8 is conducive to the recovery of the silicone strip 4 after deformation, thereby extending the service life of the silicone strip 4.

[0028] Working principle: When using the silicone sealing strip, firstly snap one side of the plastic plate 3 into the docking groove 5 on the silicone strip 4, and then install the other side of the plastic plate 3 inside the card groove 2 on the movable window frame 1;

[0029] When the movable window frame 1 rotates, the silicone strip 4 on the movable window frame 1 contacts the fixed window frame, and the silicone strip 4, the first supporting component 7 and the second supporting component 8 are deformed under the pressure of the movable window frame 1 and the fixed window frame, so that the silicone strip 4 can complete the sealing between the movable window frame 1 and the fixed window frame;

[0030] When the movable window frame 1 is separated from the fixed window frame, the first supporting member 7 and the second supporting member 8 allow the silicone strip 4 to recover, ensuring that the silicone strip 4 can recover after being flattened, which is beneficial for the silicone strip 4 to seal the connection between the movable window frame 1 and the fixed window frame, thereby extending the service life of the silicone strip 4;

[0031] When the silicone strip 4 is damaged for a long time and needs to be replaced, the silicone strip 4 is removed from the plastic plate 3, and then a new silicone strip 4 is installed on the plastic plate 3, avoiding the overall replacement of the plastic plate 3 and the silicone strip 4 and avoiding waste.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
