[0046] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0047] Reference Figure 1 to Figure 6 The three-piece combined glue injection angle code of the utility model is made into the following embodiments:

[0048] like Figures 1 to 3 As shown, the glue injection corner code 100 of the present invention is L-shaped, and the glue injection corner code 100 includes a middle corner code 110, a side corner code 120 and a screw 130. The side corner code 120 is provided with two pieces. In the horizontal direction, the two side corner codes 120 are respectively arranged on both sides of the middle corner code 110.

[0049] Among them, the middle angle code 110 includes two middle connecting arms 111, one end of the two middle connecting arms 111 is vertically connected to each other, and the ends of the two middle connecting arms 111 away from each other are provided with screw holes 112, wherein the screw holes 112 longitudinally penetrate the inner angle side and the outer angle side of the middle angle code 110, and the screws 130 can be screwed into the screw holes 112 from the outside to the inside.

[0050] Extrusion notches 113 are provided on both sides of the inner peripheral wall of the screw hole 112 along the horizontal direction of the middle connecting arm 111, wherein the extrusion notches 113 penetrate the two horizontal side surfaces of the middle angle code 110. When the screw 130 is screwed into the screw hole 112, a part of the outer periphery of the screw 130 extends out of the outside of the middle angle code 110 through the extrusion notches 113. It can be understood that the spacing between the extrusion notches 113 on both sides is smaller than the outer diameter of the screw 130.

[0051] In addition, first reinforcing guide platforms 114 are laterally protruded from both lateral sides of the middle angle bracket 110 , and the first reinforcing guide platforms 114 are disposed outside the screw holes 112 .

[0052] The middle angle bracket 110 of the present embodiment is an integral die-cast hard component. Specifically, the middle angle bracket 110 is configured as a die-cast aluminum angle bracket, which is processed by die-casting during production. The die-cast aluminum angle bracket has high rigidity and great hardness.

[0053] The screw hole 112 is directly die-cast, and only tapping is required in the later production, which greatly reduces the production cost.

[0054] The side angle code 120 includes two side connecting arms 121, one ends of the two side connecting arms 121 are vertically connected to each other, and the two side connecting arms 121 are both provided with a first hollow slot 122 corresponding to the position of the first reinforcement guide platform 114. The side angle code 120 and the middle angle code 110 are assembled by plugging the first hollow slot 122 into the first reinforcement guide platform 114.

[0055] The screw 130 of the present embodiment squeezes the side angle brackets 120 on both sides in the transverse direction through the squeezing notch 113 , so that the side angle brackets 120 expand outward in the transverse direction relative to the middle angle bracket 110 .

[0056] In this embodiment, the expansion guidance of the opposite side angle code 120 is achieved by plugging the first reinforcement guide platform 114 into the first hollow slot 122. In addition, the first reinforcement guide platform 114 can reinforce the structural strength of the screw hole 112 to avoid thread slippage and looseness between the screw 130 and the screw hole 112, thereby improving the firmness of the installation of the glue-injected angle code 100.

[0057] When in use, the two ends of the glue-injected corner code 100 are inserted into the profile, and the screw 130 is screwed into the screw hole 112. The screw 130 contacts the side corner codes 120 on both sides through the extrusion notches 113 on both sides. As the screw 130 is screwed in, the side corner codes 120 on both sides are laterally extruded and expanded to both sides, and the force is transmitted to the inner surface of the profile to automatically level it, so as to realize the connection and fixation of the glue-injected corner code 100 and the profile, improve the installation efficiency of the door and window corners, and improve the flatness of the assembly effect.

[0058] The side angle code 120 is an extruded flexible component. Specifically, the side angle code 120 is set as an extruded aluminum angle code. During production and processing, a bar workpiece can be processed into a bar by extrusion molding in advance, and then the bar workpiece is cut into a side angle code 120 of a set thickness by cutting. The side angle code 120 has a certain deformation effect and can be mass-produced by cutting and grooving, thereby reducing processing costs.

[0059] The middle angle bracket 110 is used as the main force-bearing member, and the side angle bracket 120 is used as the expansion member. In this way, when the side angle bracket 120 expands outward and contacts the profile, the side angle bracket 120 matches and contacts the profile, thereby improving the leveling effect.

[0060] like Figure 5 As shown, the screw 130 of the present embodiment is a hollow structure, and the screw 130 is provided with a glue injection through hole 131 passing through both ends. When injecting glue, the glue is injected through the outer port of the screw hole 112, and the glue can be injected into the inner corner side of the glue injection angle code 100 along the glue injection through hole 131 in the screw 130 and through the inner port of the screw hole 112. In this way, there is no need to additionally process a glue injection port on the profile, and the glue can be injected through the mounting hole of the operating screw 130 on the profile.

[0061] Furthermore, the inner wall of the first hollow slot 122 is provided with anti-slip grooves. When the first hollow slot 122 and the first reinforcement guide platform 114 are inserted into each other, in a natural state, the anti-slip grooves abut against the outer wall of the first reinforcement guide platform 114, thereby achieving a certain fixing effect and preventing the side angle code 120 from falling off the middle angle code 110.

[0062] In order to further improve the structural strength of the screw hole 112, the first reinforcement guide platform 114 of the present embodiment is arranged in the middle of the screw hole 112. The first reinforcement guide platform 114 is arranged in the middle position between the two ends of the screw hole 112. On the one hand, the stability of the guidance of the opposite side angle code 120 can be improved, and on the other hand, the firmness of the reinforcement of the screw hole 112 can be improved.

[0063] The outer end of the screw hole 112 is provided with a second reinforcement guide platform 115 on both sides along the horizontal direction. The second reinforcement guide platform 115 protrudes along the horizontal direction, and the extrusion notch 113 is set between the second reinforcement guide platform 115 and the first reinforcement guide platform 114. In this embodiment, a second reinforcement guide platform 115 is further provided to reinforce the outer port of the screw hole 112, and the extrusion notch 113 is set between the second reinforcement guide platform 115 and the first reinforcement guide platform 114, so that the two ends of the abutment between the screw 130 and the side angle code 120 are reinforced, thereby improving the firmness of the installation of the screw 130 and increasing the thrust of the screw 130 on the side angle code 120.

[0064] The outer side of the side connecting arm 121 of this embodiment is provided with a snap-in groove 127 which is slidably engaged with the second reinforcing guide platform 115 . The side connecting arm 121 is slidably engaged with the second reinforcing guide platform 115 through the snap-in groove 127 to improve the guiding effect of the expansion of the side angle code 120 .

[0065] like Figures 1 to 4 As shown, the inner corner and the outer corner of the middle angle code 110 are respectively provided with a first glue containing groove 117 and a second glue containing groove 118, and the middle angle code 110 is provided with a first inclined groove 140 at the connection between the two middle connecting arms 111 along the two lateral sides, and the two ends of the first inclined groove 140 are respectively connected to the first glue containing groove 117 and the second glue containing groove 118;

[0066] The inner corner and the outer corner of the side angle code 120 are respectively provided with a third glue containing groove 124 and a fourth glue containing groove 125, and the outer side surface of the side angle code 120 is located at the connection between the two side connecting arms 121 and is provided with a second inclined groove 150, and the two ends of the second inclined groove 150 are respectively connected to the third glue containing groove 124 and the fourth glue containing groove 125;

[0067] The first glue containing groove 117 is connected to the third glue containing groove 124 in the transverse direction, the second glue containing groove 118 is connected to the fourth glue containing groove 125 in the transverse direction, and both sides of the inner corner of the glue injection angle code 100 are provided with a first drainage groove 160 connecting the first glue containing groove 117 and the inner port of the screw hole 112, and both sides of the outer corner of the glue injection angle code 100 are provided with a second drainage groove 170 connecting the second glue containing groove 118 and the outer port of the screw hole 112.

[0068] When injecting glue, glue is applied to one of the screws 130, and the glue can flow from the inner port of one of the screw holes 112 along one of the first drainage grooves 160 to the first glue-containing groove 117, the third glue-containing groove 124 and another first drainage groove 160, so that an inner glue groove consisting of two first drainage grooves 160, the first glue-containing groove 117 and the third glue-containing groove 124 connected to each other is formed on the inner corner side of the glue injection angle code. At this time, a part of the glue fills the inner glue groove to achieve a sealed connection between the inner corner side of the glue injection angle code 100 and the profile, and the other part of the glue will flow along the first inclined groove 140 and the second inclined groove 150 flow to the second glue containing groove 118 and the fourth glue containing groove 125, and flow along the two second drainage grooves 170, and some glue will flow from the outer port of the screw hole along the second drainage groove 170 to the second glue containing groove 118 and the fourth glue containing groove 125. In this way, an outer glue groove is formed on the outer corner side of the glue injection corner code, which is composed of the two second drainage grooves 170, the second glue containing groove 118 and the fourth glue containing groove 125 interconnected. At this time, the glue fills the outer glue groove to achieve a sealed connection between the outer corner side of the glue injection corner code and the profile, thereby improving the efficiency of glue injection and the firmness of installation.

[0069] Alternatively, glue is applied to the second glue receiving groove 118, wherein a portion of the glue flows along the two second drainage grooves 170 and fills them, and another portion of the glue flows along the first inclined groove 140 and the second inclined groove 150 to the first glue receiving groove 117 and the third glue receiving groove 124, and fills the first drainage groove 160, and then flows back to the second drainage groove 170 along the screw hole 112 and the glue injection through hole 131.

[0070] The first drainage groove 160 of the present embodiment is formed between the outer corner side of the middle angle code 110 and the two side angle codes 120, and the second drainage groove 170 is formed between the inner corner side of the middle angle code 110 and the two side angle codes 120. The first drainage groove 160 and the second drainage groove 170 of the present embodiment are both formed by splicing and combining the two side angle codes 120 and the middle angle code 110. When the glue is expanded and injected, the glue can also flow into the gap between the side angle code 120 and the middle angle code 110 to improve the overall structural strength of the entire glue-injected angle code 100.

[0071] Furthermore, the outer side wall of the side connecting arm 121 is provided with a plurality of third sol grooves 126 which penetrate in the transverse direction, and the third sol grooves 126 are connected with the first drainage grooves 160, so that the outer side glue grooves also include the third sol grooves 126, which can further expand the contact area between the glue and the profile to improve the firmness of the installation.

[0072] A top block 128 with a right-angle top groove is convexly provided on the third glue-containing groove 124 and the first glue-containing groove 117. During installation, the right-angle top groove of the top block 128 is used to support the chamfered corners of adjacent profiles, so that the splicing of the profiles is more fitted.

[0073] Further, if Figure 3 and Figure 6 As shown, a guide ridge 141 is provided at the inner end of the first inclined groove 140, and the guide ridge 141 extends along the first inclined groove 140. The inner end of the guide ridge 141 is connected to the top block 128 on the first glue-containing groove 117, and two guide grooves 142 are formed between the two sides of the guide ridge 141 and the two side walls of the first inclined groove 140, which are respectively connected to the first drainage grooves 160 on both sides.

[0074] When applying glue, the glue first flows along one of the first drainage grooves 160 to the third glue holding groove 124 and the first glue holding groove 117 on one side of the top block 128, and then the glue flows into one of the guide grooves 142, and part of the glue flows to the outer corner along the first inclined groove 140, and another part of the glue flows along the other guide groove 142 to the third glue holding groove and the first glue holding groove on the other side of the top block 128, and then flows to the other first drainage groove 160, which has a guiding effect on the glue and prevents all the glue from flowing to the other first drainage groove 160 and causing overflow of the other screw hole 112.

[0075] Furthermore, the middle angle bracket 110 is provided with a plurality of guide plug-in platforms 119 in a frame shape on both lateral sides thereof, and the side angle bracket 120 is provided with a plurality of second hollow slots 129 which are inserted into the guide plug-in platforms 119 one by one.
