Description

Technical Field

[0001] This utility model relates to the field of interior door technology, and in particular to a U-shaped strip for installing glass in interior doors. Background Technology

[0002] The current installation structure for interior door glass typically employs the following method: first, a U-shaped strip is embedded into the door panel groove, and then silicone sealant is injected into the U-shaped strip to bond it to the glass. However, the existing design of the U-shaped strip makes it easy for the sealant to overflow from the groove after injection, preventing it from effectively bonding the glass and the door panel, ultimately leading to the glass detaching from the door panel. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a U-shaped strip for installing glass in interior doors.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An interior door glass mounting U-shaped strip includes a bottom strip and two side strips respectively located at both ends of the bottom strip. The bottom strip and the two side strips together form a U-shaped strip body with an opening and installed in a door leaf groove. The bottom strip has at least one first support rib and at least one glue-applying through hole on the side away from the opening. When the first support rib abuts against the bottom end face of the door leaf groove, a glue flow channel is formed between the U-shaped strip body and the inner side of the door leaf groove, which enters through the glue-applying through hole. Each of the two side strips has at least one first anti-overflow rib on the side that is close to each other.

[0006] Furthermore, a second anti-overflow rib is provided on the side of the two side strips that are far apart from each other. The second anti-overflow rib abuts against the side end face of the door leaf groove. The glue flow channel includes a first channel and a second channel that are interconnected. The area between the bottom strip and the bottom end face of the door leaf groove constitutes the first channel, and at least a portion of the area between the side strip and the side end face of the door leaf groove constitutes the second channel.

[0007] Furthermore, one end of each of the first overflow ribs is disposed on the side strip, and the other end of each of the first overflow ribs is inclined toward the bottom strip.

[0008] Furthermore, each of the first overflow ribs has a second supporting rib on the side away from the opening.

[0009] Furthermore, a positioning rib is provided on the side of the two side strips that are far apart from each other, and the positioning rib is adapted to the groove of the door leaf.

[0010] Furthermore, one end of each positioning rib is disposed on the side strip, and the other end of each positioning rib is inclined toward the door leaf groove.

[0011] Furthermore, one end of each of the two side strips is connected to the bottom strip, and the other end of each of the two side strips is provided with a third supporting rib located at the opening.

[0012] Furthermore, the adhesive-coating through-holes are waist-shaped holes, and multiple holes are arranged along the length of the bottom strip.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model proposes a U-shaped strip for installing interior door glass, comprising a bottom strip and two side strips respectively located at both ends of the bottom strip. The bottom strip and the two side strips together form a U-shaped strip body with an opening and installed in the door leaf groove. The bottom strip has at least one first support rib and at least one glue-applying through hole on the side away from the opening. With the first support rib abutting against the bottom surface of the door leaf groove, a glue-flowing channel is formed between the U-shaped strip body and the inner side of the door leaf groove, allowing glue to enter through the glue-applying through hole. The two side strips each have at least one first anti-overflow rib on their sides closest to each other. When the glass is inserted into the U-shaped strip, most of the glass glue flows into the glue-flowing channel, and a small portion flows into the space between the glass panel and the side strips. This not only prevents the glass glue from overflowing from the groove opening but also effectively bonds and fixes the door leaf, U-shaped strip body, and glass panel through the glass glue, improving the reliability of the fixation and preventing the glass panel from detaching due to ineffective bonding.

[0015] 2. The present invention proposes an indoor door glass installation U-shaped strip, wherein each first overflow rib is provided with a second support rib on the side away from the opening. When the glass is installed, the elastic first overflow rib will undergo elastic deformation, and the second support rib plays the role of providing a certain support force to the first overflow rib.

[0016] 3. The present invention proposes an indoor door glass installation U-shaped strip, wherein the two sides of the strip are provided with positioning ribs on the side that are far apart from each other. The positioning ribs are adapted to the door leaf groove and play a snap-fit ​​positioning role. The positioning ribs and the protrusions at the door leaf groove cooperate with each other to fix the U-shaped strip body in the door leaf groove. Attached Figure Description

Detailed Implementation

[0027] The following is combined with Figure 1-8 This utility model will be described in detail.

[0028] An interior door glass mounting U-shaped strip includes a bottom strip 101 and two side strips 102 respectively located at both ends of the bottom strip 101. The bottom strip 101 and the two side strips 102 together form a U-shaped strip body 10 with an opening 103 and installed in a door leaf groove 20. The bottom strip 101 has at least one first support rib 1011 and at least one glue-applying through hole 1012 on the side away from the opening 103. When the first support rib 1011 abuts against the bottom end face of the door leaf groove 20, a glue flow channel 30 is formed between the U-shaped strip body 10 and the inner side of the door leaf groove 20, which enters through the glue-applying through hole 1012. The two side strips 102 each have at least one first anti-overflow rib 1021 on the side that is close to each other. When the glass is inserted into the U-shaped strip, most of the glass glue 50 flows to the glue channel 30, and a small portion flows to the space between the glass panel 40 and the side strip 102. This not only prevents the glass glue 50 from overflowing from the groove 201, but also effectively uses the glass glue 50 to bond and fix the door leaf, the U-shaped strip body 10, and the glass panel 40, improving the reliability of the fixation and avoiding the glass panel 40 from detaching due to ineffective bonding.

[0029] Furthermore, a second overflow-stopping rib 1022 is provided on the side of the two side strips 102 that are far apart from each other. The second overflow-stopping rib 1022 abuts against the side end face of the door leaf groove 20. The glue flow channel 30 includes a first channel 301 and a second channel 302 that are interconnected. The area between the bottom strip 101 and the bottom end face of the door leaf groove 20 constitutes the first channel 301. At least a portion of the area between the side strip 102 and the side end face of the door leaf groove 20 constitutes the second channel 302.

[0030] Specifically, the first support rib 1011 is provided to prevent the bottom strip 101 from being tightly attached to the bottom surface of the door leaf groove 20. If it were tightly attached, only the area corresponding to the glue application hole 1012 on the inner side of the door leaf groove 20 could come into contact with the glass glue 50. The first support rib 1011 is provided to form the glue flow channel 30. The first support rib 1011 can be positioned at any location on the side of the bottom strip 101 away from the opening 103, as long as the first support rib 1011 has a notch 1013 that allows the glass glue 50 to pass through. Alternatively, a small section of the first support rib 1011 can be provided at both the upper and lower ends of the bottom strip 101. Preferably, such as... Figure 2 and Figure 8 As shown, two first support ribs 1011 are respectively located at the left and right ends of the adhesive coating through hole 1012. Each first support rib 1011 has several discontinuous notches 1013. The length of each notch 1013 is greater than or equal to the diameter of the adhesive coating through hole 1012. After the glass glue 50 is squeezed into the adhesive coating through hole 1012, it smoothly fills and diffuses the entire adhesive flow channel 30 through each notch 1013. If there is no notch 1013, the glass glue 50 will be blocked by the complete first support rib 1011 and will not be able to continue to diffuse.

[0031] The thickness of the first support rib 1011 is 3mm, therefore the gap between the bottom strip 101 and the bottom end face of the door leaf groove 20 is also 3mm; Figure 7 As shown, the bottom end face of the door leaf groove 20 is the inner end face of the door leaf groove 20 facing the groove opening 201, while the side end faces of the door leaf groove 20 are located at both ends of the bottom end face and have continuous serrated "V" shaped openings. The bottom end face and the two side end faces together constitute the inner side of the door leaf groove 20. The groove opening 201 of the door leaf groove 20 is consistent with the opening direction of the opening 103 of the U-shaped strip body 10. Two first anti-overflow ribs 1021 are provided on each side of the two side strips 102 that are close to each other. The first anti-overflow ribs 1021 can fit with the glass plate 40 after the glass plate 40 is installed, which can protect the edge of the glass plate 40 and prevent the glass glue 50 from overflowing outward through the space between the glass plate 40 and the side strip 102. The U-shaped strip body 10 has a certain elasticity, which can not only fit into the door leaf groove 20 itself, but also clamp the glass plate 40 through the first anti-overflow ribs 1021.

[0032] The second anti-overflow rib 1022 provides support and fixation, and extends the second channel 302, while also preventing the self-flowing adhesive channel 30 of the silicone sealant 50 from overflowing the groove 201 of the door leaf groove 20. Ideally, the second anti-overflow rib 1022 can completely prevent the silicone sealant 50 from overflowing. However, in reality, due to the possible gap between the continuous "V"-shaped opening on the side end face of the door leaf groove 20 and the second anti-overflow rib 1022, a small amount of silicone sealant 50 may flow through this gap. That is, there may be a small amount of adhesive between the second anti-overflow rib 1022 and the positioning rib 1024, but this adhesive will also be blocked from overflowing by the positioning rib 1024.

[0033] In this embodiment, one end of each first overflow rib 1021 is disposed on the side strip 102, and the other end of each first overflow rib 1021 is inclined toward the bottom strip 101.

[0034] In this embodiment, a second support rib 1023 is provided on the side of each first overflow rib 1021 away from the opening 103. Specifically, when the glass plate 40 is installed, the elastic first overflow rib 1021 will undergo elastic deformation, and the second support rib 1023 will provide a certain support force to the first overflow rib 1021.

[0035] In this embodiment, a positioning rib 1024 is provided on the side of the two side strips 102 that are far apart from each other. The positioning rib 1024 is adapted to the groove 201 of the door leaf groove 20. Furthermore, one end of each positioning rib 1024 is provided on the side strip 102, and the other end of each positioning rib 1024 is inclined towards the groove 201 of the door leaf groove 20. Specifically, the positioning rib 1024 plays a snap-fit ​​and positioning role. The positioning rib 1024 and the protrusion at the groove 201 of the door leaf groove 20 cooperate with each other to fix the U-shaped strip body 10 in the door leaf groove 20.

[0036] In this embodiment, one end of each side strip 102 is connected to the bottom strip 101, and the other end of each side strip 102 is provided with a third support rib 1025 located at the opening 103. Specifically, the third support rib 1025 is used to fix the glass plate 40.

[0037] In this embodiment, the adhesive-coating through-hole 1012 is a waist-shaped hole, and multiple holes are arranged along the length of the bottom strip 101.

[0038] The U-shaped strip for installing glass in interior doors, as proposed in this utility model, is used as follows:

[0039] like Figures 4-6 As shown, Figure 5 The arrow indicates the diffusion direction of the glass glue 50 after being pressed. (1) Insert the U-shaped strip body 10 with a certain elasticity into the door leaf groove 20; (2) Apply glass glue 50 to the inside of the U-shaped strip body 10, especially the glue application hole 1012; (3) Place the glass plate 40 into the U-shaped strip body 10 from the opening 103. The glass plate 40 squeezes the glass glue 50, so that most of the glass glue 50 enters the glue flow channel 30 from the glue application hole 1012. The remaining small part of the glass glue 50 that does not enter the glue flow channel 30 remains inside the U-shaped strip body 10, but does not overflow the groove 201 of the door leaf groove 20 under the blocking effect of the first overflow rib 1021.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
