Description

Technical Field

[0001] This utility model belongs to the technical field of door and window installation accessories, specifically relating to a self-expanding guide plate for door and window glue injection. Background Technology

[0002] Adhesive-filled corner brackets (also known as door and window corner adhesive patches) are sheet-like parts that are permanently bonded together by injecting corner adhesive between the corner bracket and the profile. This effectively prevents the aluminum profile and corner bracket from loosening or misaligning, greatly improving the stability and sealing of the window. Therefore, they are widely used in thermally broken aluminum doors and windows.

[0003] Because of inherent errors in the cutting of corner brackets by the cutting machine, the flatness of the corner brackets during splicing is difficult to guarantee, affecting the glue application effect. If the corner brackets lack drainage channels, the glue cannot be guaranteed to flow evenly into every gap, potentially leading to uneven glue application and affecting the sealing and waterproofing of doors and windows. Furthermore, some glue will flow onto the profiles or into the cavities, not only wasting glue but also causing time-consuming and labor-intensive installation later, impacting assembly efficiency.

[0004] Therefore, to address the issues of uneven glue application and easy glue overflow in the use of existing glue-filled corner brackets, a more reasonable technical solution is needed to resolve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a self-expanding guide plate for door and window glue injection, so as to solve the problems of uneven glue injection and easy glue overflow in the use of existing glue injection corner brackets.

[0006] To achieve the above objectives, this utility model provides a self-expanding guide plate for door and window glue injection, including a main board, a first groove at the top of the main board, a second groove at the tail of the main board, and the main board being dovetail-shaped; the main board has a top surface and a bottom surface opposite each other, and an overflow groove extending along its symmetry line is provided on the top surface, with the two ends of the overflow groove respectively penetrating the first groove and the second groove.

[0007] The top surface is provided with a first guide groove, which is configured in two sets and respectively disposed on both sides of the overflow groove. One end of the first guide groove extends to the side wall of the motherboard, and the other end passes through the overflow groove.

[0008] In one possible design, the motherboard includes two integrally formed wing plates, and the overflow groove is formed in the connection area between the two wing plates;

[0009] The first guide channel is L-shaped and includes an inclined section and an extended section. The extension direction of the inclined section is parallel to the length direction of the wing plate, and the extended section is parallel to the width direction of the wing plate and extends through the inclined section.

[0010] In one possible design, the corner where the inclined segment meets the extended segment is rounded.

[0011] In one possible design, the dimensions of the end of the extension gradually increase along the direction close to the sidewall of the wing to form an arc-shaped expansion angle.

[0012] In one possible design, the motherboard includes two integrally connected wing plates, each wing plate also having a second flow channel, the second flow channel being spaced apart from the inclined section of the first flow channel, and the second flow channel penetrating the second groove.

[0013] In one possible design, the second guide channel is located on the side close to the second groove.

[0014] In one possible design, the motherboard includes two integrally connected wing plates, which are symmetrically arranged and have clearance grooves on their edges.

[0015] In one possible design, the motherboard includes two integrally connected wing plates, the corners of which are set as smooth, rounded chamfers.

[0016] In one possible design, the main board includes two integrally connected wing plates, the thickness of which gradually decreases at the tail end away from the apex to form a slope.

[0017] In one possible design, the bottom surface of the motherboard is provided with a limiting platform, and the limiting platform is provided with a limiting groove.

[0018] Through the aforementioned technical solution, the cooperation of the first guide channel and the overflow channel allows the injected adhesive to gradually flow and evenly distribute across the entire main board, preventing adhesive overflow and waste, and reducing resource waste. Furthermore, the design of this self-expanding guide plate for door and window adhesive injection ensures a tight bond between the plate and the profile, guaranteeing a sealing effect and improving the waterproofness, airtightness, and sound insulation of the doors and windows. Because the adhesive can flow and distribute evenly, the efficiency and quality of adhesive injection are also improved, reducing quality problems caused by uneven adhesive injection.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0024] According to a first aspect of this utility model, a self-expanding guide plate for door and window adhesive injection is provided. Wherein, Figure 1 and Figure 2 One specific embodiment is shown.

[0025] See Figure 1 and Figure 2 As shown, the self-expanding adhesive guide plate for door and window injection includes a main board 1. The top of the main board 1 has a first groove 21, and the tail of the main board 1 has a second groove 22. The main board 1 is dovetail-shaped. The main board 1 has a top surface and a bottom surface. The top surface has an overflow groove 3 extending along its symmetrical line. The two ends of the overflow groove 3 are respectively connected to the first groove 21 and the second groove 22. The top surface has a first guide groove 4. The first guide groove 4 is configured in two sets and is respectively set on both sides of the overflow groove 3. One end of the first guide groove 4 extends to the side wall of the main board 1, and the other end is connected to the overflow groove 3. In this way, the injected adhesive can gradually flow through the first guide groove 4 to the overflow groove 3, and then flow out through the first groove 21 and the second groove 22, so that the self-expanding adhesive guide plate for door and window injection can be tightly bonded to the profile to ensure the sealing effect. At the same time, it is also beneficial to make the adhesive flow and distribution evenly, avoid the overflow and waste of adhesive, and reduce the waste of resources.

[0026] The main board 1 is dovetail-shaped, which increases the contact area between the main board 1 and the profile, improving the bonding strength. The top and bottom of the main board 1 are respectively provided with a first groove 21 and a second groove 22. The groove design allows for better matching with specific parts of the door and window profile, enabling the main board 1 to be accurately positioned as needed. The overflow groove 3 on the top surface extends along the symmetry line of the main board 1, and its two ends pass through the first groove 21 and the second groove 22 respectively. After injection, the adhesive can flow smoothly through the entire main board 1 and out through the grooves, bonding tightly with the profile. Two sets of first guide grooves 4 are configured, respectively located on both sides of the overflow groove 3. This layout helps to evenly distribute the adhesive during injection, preventing excessive accumulation in any one area. One end of the first guide groove 4 extends to the side wall of the main board 1, and the other end passes through the overflow groove 3, which facilitates the flow of adhesive from the side wall of the main board 1 and gradually through the guide groove to the overflow groove 3, achieving uniform adhesive injection.

[0027] Through the above technical solution, the cooperation of the first guide channel 4 and the overflow channel 3 allows the injected adhesive to gradually flow and be evenly distributed across the entire main board 1, avoiding adhesive overflow and waste, and reducing resource waste. Furthermore, based on the design of this self-expanding guide plate for door and window adhesive injection, the guide plate can be tightly bonded to the profile, ensuring a sealing effect and improving the waterproofness, airtightness, and sound insulation of the doors and windows. Because the adhesive can flow and distribute evenly, the efficiency and quality of adhesive injection are improved, reducing door and window quality problems caused by uneven adhesive injection.

[0028] In one embodiment provided in this disclosure, the main board 1 includes two integrally formed wing plates 10, and an overflow groove 3 is formed in the connection area between the two wing plates 10; wherein, the first guide groove 4 is L-shaped and includes an inclined section 41 and an extension section 42, the extension direction of the inclined section 41 is parallel to the length direction of the wing plate 10; the extension section 42 is parallel to the width direction of the wing plate 10 and extends through the inclined section 41.

[0029] The inclined section 41 of the first guide channel 4 extends parallel to the length of the wing plate 10, which helps guide the flow of adhesive. The extended section 42 is parallel to the width of the wing plate 10 and is continuous with the inclined section 41, which can make the adhesive evenly distributed, increase the bonding area with the profile, and thus enhance the bonding strength and improve the sealing effect.

[0030] Furthermore, the corner between the inclined section 41 and the extension section 42 is rounded. This design allows the adhesive to flow smoothly and prevents it from accumulating at the corner, thus avoiding affecting the adhesive distribution. The rounded corner design at the corner between the inclined section 41 and the extension section 42 ensures the adhesive flows smoothly and prevents it from accumulating at the corner, thereby avoiding affecting the adhesive distribution.

[0031] In one embodiment provided in this disclosure, the dimension of the end of the extension section 42 gradually increases along the direction close to the sidewall of the wing plate 10 to form an arc-shaped expansion angle 43. The arc-shaped expansion angle 43 can further improve the flow performance of the adhesive, reduce flow resistance, and allow the adhesive to flow more smoothly from the guide channel into the overflow channel 3, and then flow out of the main plate 1 to bond with the profile. At the same time, the arc-shaped expansion angle 43 also helps to reduce eddies and turbulence in the flow of adhesive, reduce energy loss, and improve glue injection efficiency.

[0032] In this disclosure, the main board 1 includes two integrally connected wing plates 10. Each wing plate 10 is also provided with a second flow guide trough 5. The second flow guide trough 5 is spaced apart from the inclined section 41 of the first flow guide trough 4, and extends through the second groove 22. The main board 1 is composed of two integrally connected wing plates 10, a design that enhances the overall integrity and stability of the main board 1. The second flow guide trough 5, located on the wing plate 10 and spaced apart from the inclined section 41 of the first flow guide trough 4, helps to disperse the flow of adhesive and prevent accumulation within a single flow guide trough. The second flow guide trough 5 extends through the second groove 22, allowing adhesive to flow directly into the second groove 22, further improving the fluidity and uniformity of the adhesive distribution.

[0033] By setting two sets of flow channels (first flow channel 4 and second flow channel 5), the mainboard 1 design of this disclosure can more effectively guide the flow of adhesive, enabling the adhesive to be evenly distributed on the mainboard 1. The design that runs through the grooves allows the adhesive to flow more smoothly, thereby enhancing the bonding strength with the profile, achieving better sealing effect and connection strength, and helping to reduce resource waste.

[0034] Furthermore, the second guide channel 5 is located on the side close to the second groove 22, allowing the adhesive to flow into the second groove 22 more directly and smoothly during the flow process, reducing the complexity and resistance of the flow path. This shortens the flow distance of the adhesive from the guide channel to the groove, reduces energy loss during the flow process, and improves the adhesive injection efficiency.

[0035] In one embodiment provided in this disclosure, the main board 1 includes two integrally connected wing plates 10, which are symmetrically arranged to enhance the stability and strength of the overall structure. Furthermore, the edges of the wing plates 10 are provided with clearance grooves 6, allowing the sides of the wing plates 10 to be connected to the profiles via adhesive, thereby improving the structural strength of the doors and windows.

[0036] In this disclosure, the main board 1 includes two integrally connected wing plates 10, the corners of which are all set as smooth arc-shaped chamfers 11. The smooth arc-shaped chamfers 11 reduce the sharpness of the product edges, reduce stress concentration of the material at the corners, reduce the risk of breakage due to external impact or vibration, and improve the durability of the product.

[0037] In one embodiment provided in this disclosure, the main board 1 includes two integrally connected wing plates 10. The thickness of the tail portion of the wing plate 10 gradually decreases in the direction away from the apex corner to form a bevel 12. The design of the bevel 12 allows adhesive to be filled between the connecting piece and the door / window profile, ensuring the connection strength and sealing performance of the door / window profile. In addition, the gradually thinning tail portion may allow the wing plate 10 to better adapt to more complex usage scenarios in a specific direction.

[0038] In this disclosure, the bottom surface of the motherboard 1 is provided with a limiting platform 71, and the limiting platform 71 is provided with a limiting groove 72. The limiting groove 72 is a groove or opening provided on the limiting platform 71, which can be used to cooperate with corresponding protrusions or fasteners on other structures to further lock the position of the motherboard 1, thereby improving the accuracy and efficiency of the motherboard 1 during installation. In addition, this design can also enhance the stability of the motherboard 1 and prevent loosening or displacement caused by vibration or external force.

[0039] Finally, it should be noted that this utility model is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this utility model. The above specific embodiments should not be construed as limiting the scope of protection of this utility model, which should be determined by the claims, and the description can be used to interpret the claims.
