Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corner codes, and in particular to a glue-filled corner code structure. Background Technology
[0002] When assembling door and window profiles, corner brackets are typically used for connection. The corner brackets are inserted into the profiles at both ends, and after connection, adhesive is injected into the corner brackets to fill the gaps between the brackets and the profiles, as well as the joints between the profiles, thereby improving the stability and sealing of the profiles. Referring to the utility model patent (publication number: CN216767172U): "An Injection Corner Bracket," it can be seen that the currently available injection corner brackets mainly consist of a main body and end caps symmetrically arranged on both sides of the main body. Vertical straight channels are provided on both the inner and outer sides of the right angle of the main body. The end cap is provided with a first transverse flow channel, a second transverse flow channel and a middle flow channel that are interconnected. The middle flow channel is connected to two vertical straight channels, and the two transverse flow channels are connected to two countersunk hollow screws. When applying glue, the glue can enter from one of the screws, flow out of the first transverse flow channel, and when it flows to the middle flow channel, the glue will flow through the longitudinal channel to the groove at the corner of the corner bracket, and at the same time flow through the second transverse flow channel to the other screw, and finally flow out from the other screw. When the glue flows out from the other screw, it means that the glue application is complete, thereby filling the gap between the corner bracket and the profile, as well as the gap of the profile splicing.
[0003] However, the existing glue injection angle code structure is not reasonable. When the glue flows through the central channel, it is guided and diverted, flowing into the vertical channel through the central channel and into the screw through another horizontal channel. However, the glue diversion is easily affected by the size of the angle code, which may cause the glue in the vertical channel to be too full before the glue flows out from the other screw, or the glue in the vertical channel may not be full after the glue flows out from the other screw. This can easily lead to excessive glue injection or glue leakage. If the vertical channel is set too deep, the vertical channel may not be full after the glue flows out from the other screw. In addition, because the gaps on both sides of the angle code are different sizes after it is installed in the profile, the end cap does not fit the inner wall of the profile, and the glue can easily overflow from the gaps, thus affecting the sealing and stability. Utility Model Content
[0004] The present invention provides a glue injection corner code structure to prevent excessive or incomplete glue injection.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue injection corner code structure, comprising a main body and a first guide plate and a second guide plate disposed on both sides of the main body. Both ends of the main body are provided with inner cavities, and both outer surfaces are provided with grooves. The first guide plate and the second guide plate are each provided with a plug-in block inserted into the end of the groove on one side facing each other, and glue-flowing grooves are respectively provided on the other side. The grooves are provided with countersunk hollow screws for supporting the two plug-in blocks. The corner of the main body is provided with a flat corner, which is connected between the two glue-flowing grooves to form a glue-flowing channel. The beginning of the glue-flowing channel is connected to one of its inner cavities, and the end is connected to the other inner cavity.
[0006] Furthermore, the inner side of the main body is provided with a recess.
[0007] Furthermore, the end of the recess is connected to the adhesive groove of the first guide plate and / or the second guide plate.
[0008] Furthermore, each of the two adhesive channels has a centerline adhesive channel at one end corresponding to the centerline of the main body, and the other end is provided with an adhesive passage hole that is connected to the two inner cavities respectively. The end of the centerline adhesive channel is connected to the flat corner.
[0009] Furthermore, the bottom of the groove is provided with a threaded hole for connecting countersunk hollow screws, and the two plug blocks are provided with arc notches on their facing sides, and the two arc notches and threaded holes are all located on the same center line.
[0010] Furthermore, the countersunk hollow screw has a through hole that communicates with the inner cavity.
[0011] Furthermore, the main body is provided with a through positioning cavity, and both the first guide plate and the second guide plate are provided with protrusions that match the positioning cavity.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by guiding the glue through the glue channel, the glue enters the corresponding inner cavity from one through hole and flows through the glue channel. After filling the glue channel, it overflows from the other through hole, making the glue flow more uniform and making it easier for people to know the glue injection completion status. Moreover, the two guide plates are opened and attached to the inner wall of the profile simultaneously by countersunk hollow screws, preventing the occurrence of excessive glue injection or glue leakage, thereby improving the stability and sealing of the profile.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] As shown in the attached figure, this utility model discloses a glue-injection corner bracket structure, comprising a main body 1 and a first guide plate 2 and a second guide plate 3 disposed on both sides of the main body 1. In conjunction with existing structures, the main body 1 is symmetrically provided with two connecting sections, which are distributed at right angles. During installation, the two connecting sections are respectively inserted into the cavities of two profiles, with the joint of the two profiles corresponding to the centerline of the main body 1. The shapes of the first guide plate 2 and the second guide plate 3 correspond to the shape of the main body 1, forming a right angle. Both ends of the main body 1 are provided with inner cavities 11, and both outer surfaces are provided with grooves 103. That is, both connecting sections are provided with inner cavities 11, and the outer surfaces of both connecting sections are provided with grooves 103. The first guide plate 2 and the second guide plate 3, facing each other, are each provided with an insertion block 301 that inserts into the end of the groove 103, and the other sides are respectively provided with glue-feeding grooves. 23. A countersunk hollow screw 110 is inserted through the groove 103 to open the two insertion blocks 301 located in the groove 103, thereby opening the first guide plate 2 and the second guide plate 3 so that they abut against the inner wall of the profile. Specifically, the countersunk hollow screw 110 has a conical head. When the countersunk hollow screw 110 is inserted into the groove 103, its head gradually approaches the insertion block 301, and the first guide plate 2 and the second guide plate 3 are gradually opened by the screw head. The opening process is smoother. The inclined surface of the head pushes the insertion block 301 open to both sides. At the same time, glue is injected by the countersunk hollow screw 110. The first guide plate 2 and the second guide plate 3 are respectively provided with glue grooves 23 on the side away from the main body 1. The first guide plate 2 and the second guide plate 3 are the same guide plate. (Refer to...) Figure 4 The corner of the main body 1 is set as a flat corner portion 13. When the corner bracket is installed into the profile, the flat corner portion 13 and the two profiles form a triangular space. Figure 4 The dotted line represents the inner wall of the profile. The angle between the flat corner 13 and the outer side of the connecting section is preferably 45°. The profile wall located at the flat corner 13 is the waist of a triangle, and the flat corner 13 is the base of the triangle. The glue filling the space after injection automatically forms a triangular structure, which can further improve its connection stability. The flat corner 13 is connected between the two glue channels 23 to form a glue channel. The beginning of the glue channel is connected to one of its inner cavities 11, and the end is connected to the other inner cavity 11, ensuring that the glue flows from one inner cavity 11 to fill the glue channel before entering the other inner cavity 11. The flat corner 13 serves as the connection point of the glue channel, so that the glue must pass through the flat corner 13 before entering the other inner cavity 11. It should be noted that the corner bracket structure uses existing injection glue, specifically a paste-like viscous substance, which is supplied by injection equipment such as a glue gun.
[0024] This utility model discloses a glue injection corner bracket structure that eliminates the glue injection hole and the vertical straight channel at the corner, making the corner bracket structure more concise. The glue is guided by a set glue flow channel, allowing it to enter the corresponding inner cavity 11 from one countersunk hollow screw 110. The glue flows through the glue flow channel, and after filling the channel, it overflows from the other countersunk hollow screw 110. Specifically, the glue is injected from one countersunk hollow screw 110, enters the corresponding inner cavity 11, flows out to the first glue flow groove 23, then flows through the flat corner portion 13, and finally reaches the second glue flow groove 23 on the second guide plate 3. At this point, the flat corner portion 13 is filled with glue. After flowing from the second glue channel 23 into the corresponding inner cavity 11, it flows out through another countersunk hollow screw 110. At this point, the glue injection is complete. This structure makes the glue flow more uniform, and it is easier for people to know the completion status of the glue injection. Moreover, the insertion blocks 301 of the first guide plate 2 and the second guide plate 3 are inserted into the end of the groove 103. When the countersunk hollow screw 110 passes through the main body 1, its tapered head will automatically open the insertion blocks 301, so that the first guide plate 2 and the second guide plate 3 open simultaneously to both sides and finally abut against and fit against the inner wall of the profile, preventing the occurrence of excessive glue injection or glue leakage, thereby improving the stability and sealing of the profile.
[0025] In this embodiment, the inner side of the main body 1 is provided with a recess 14. Adhesive is also injected into the recess 14 to connect and seal the profile edge located inside the corner of the corner bracket. This is an existing structure. The end of the recess 14 is connected to the adhesive channel 23 of the first guide plate 2 and / or the second guide plate 3. Specifically, see reference... Figure 6 As shown, one end of the recess 14 is connected to the adhesive channel 23 of the first guide plate 2 or the second guide plate 3. It should be noted that, preferably, the recess 14 is connected to the adhesive channel 23 of the second guide plate 3. That is, the first guide plate 2 is equipped with a baffle to prevent the adhesive from entering the recess 14 first, and the adhesive is injected from the inner cavity 11 corresponding to the adhesive channel 23 of the first guide plate 2. The adhesive first passes through the adhesive channel 23 of the first guide plate 2, passes through the flat corner 13, and then enters the adhesive channel 23 of the second guide plate 3. At this time, the adhesive is then diverted to the recess 14 and the inner cavity 11 corresponding to the adhesive channel 23. II. Reference Figure 7 As shown, both ends of the recess 14 are connected to two adhesive channels 23. Specifically, the adhesive flows from one of its inner cavities 11 to the adhesive channel 23 of the first guide plate 2, and is split in the adhesive channel 23 to the flat corner 13 and the recess 14, and then flows from the flat corner 13 and the recess 14 to the other adhesive channel 23.
[0026] In this embodiment, one end of each of the two adhesive channels 23 includes a centerline adhesive channel 200 corresponding to the centerline of the main body 1, and the other end is provided with an adhesive passage hole 230 respectively connected to the two inner cavities 11. The end of the centerline adhesive channel 200 is connected to the flat corner portion 13. The adhesive channel 23 is specifically divided into a centerline adhesive channel 200 and a corner section. The centerline adhesive channel 200 is the part corresponding to the centerline of the main body 1. The adhesive passage hole 230 is provided at the end of the corner section away from the centerline adhesive channel 200. The end of the centerline adhesive channel 200 away from the corner section is connected to the flat corner portion 13. The adhesive passage hole 230 is used to connect the inner cavity 11 and the adhesive channel 23 so that the adhesive can pass through.
[0027] In this embodiment, the bottom of the groove 103 is provided with a threaded hole 12 for connecting the countersunk hollow screw 110. Both of the two insert blocks 301 have arc-shaped notches on their facing sides, and both arc-shaped notches and threaded holes 12 are located on the same centerline. The countersunk hollow screw 110 is an existing assembly part. The countersunk hollow screw 110 has a through hole that connects to the inner cavity 11. One end of the countersunk hollow screw 110 is inserted into the inner cavity 11 of the main body 1, so that one end of the through hole of the countersunk hollow screw 110 connects to the inner cavity 11. The main body 1 has a through positioning cavity 100. The first guide plate 2 and the second guide plate 3 are both provided with protrusions 300 that match the positioning cavity 100. When the first guide plate 2 and the second guide plate 3 are in the open state, there is a small gap between them and the main body 1. The cooperation between the protrusions 300 and the positioning cavity 100 makes the opening process smoother while preventing glue from entering the positioning cavity 100, thereby preventing glue waste.
[0028] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
