Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window accessories technology, and in particular to a three-body multi-functional corner bracket. Background Technology
[0002] Angle brackets are accessories that assemble two profiles set at 90° together. Existing angle brackets are prone to uneven expansion when applying glue to expansion screws, leading to uneven glue application. Furthermore, existing angle brackets rely primarily on time control for glue application, which can result in incomplete application or excessive glue waste. Utility Model Content
[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a three-body multi-functional corner code. During glue injection, the two corner code cover plates can expand evenly, the glue can be applied evenly, and the effect of glue injection can be observed in time.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] The three-body multi-functional corner code includes a corner code body and corner code cover plates symmetrically arranged on both ends of the corner code body. The corner code body has two symmetrical glue injection grooves on both ends of its body. The outer right-angled surface of the corner code body is provided with screw through holes that communicate with the glue injection grooves. Glue injection expansion screws are inserted into both screw through holes. The end faces of the two corner code cover plates away from the corner code body are respectively provided with glue-flowing grooves that connect the two glue injection grooves and the inner and outer right-angled surfaces of the corner code body. Each corner code cover plate is provided with a first abutting member and a second abutting member that abut against the two glue injection expansion screws. The first abutting member has one abutting point with the glue injection expansion screw, and the second abutting member has two abutting points with the glue injection expansion screw.
[0006] In one embodiment, the first abutting member is inserted from the glue injection groove and abuts against the glue injection expansion screw.
[0007] In one embodiment, the outer right-angled surface of the corner bracket body is recessed inward at the position of the screw through hole to form a recess that extends through both ends of the corner bracket body, and the second abutting member is inserted from the recess and abuts against the glue-filled expansion screw.
[0008] In one embodiment, the second abutment has a U-shaped structure, with its two ends abutting against the glue-injecting expansion screw.
[0009] In one implementation, the outer right angle of the corner code body is recessed in the direction of the inner right angle to form an outer adhesive channel, and the inner right angle of the corner code body is recessed in the direction of the outer right angle to form an inner adhesive channel. The adhesive grooves on the two corner code covers are respectively connected to the inner adhesive channel and the outer adhesive channel.
[0010] In one embodiment, the corner code cover plate is provided with glue injection holes through the two glue injection slots respectively. The glue flow groove includes a diagonal groove along the diagonal of the corner code cover plate and a right-angle groove connecting the two glue injection holes. The diagonal grooves are respectively connected to the inner glue flow channel and the outer glue flow channel.
[0011] In one embodiment, a guide rib is provided in the diagonal groove, and the guide rib is used to position and cooperate with the profile.
[0012] In one embodiment, the corner code body has several positioning slots extending through both ends, and the two corner code cover plates are respectively provided with positioning ribs that are inserted into the several positioning slots.
[0013] Compared with traditional technologies, the beneficial effects of the three-body multifunctional corner code described in this utility model are:
[0014] This utility model features two through-holes in the corner bracket body, and screw holes communicating with these through-holes on the outer right-angled surface of the corner bracket body, facilitating the insertion of expansion screws into the through-holes. Furthermore, two glue-feeding grooves communicating with the two through-holes are provided on the two corner bracket cover plates. Each cover plate has a first abutment and a second abutment that abut against the two expansion screws, creating three contact points between the first and second abutments and the expansion screws. Thus, when a user applies glue through one of the expansion screws, the glue enters the adjacent through-hole from that screw, then flows along the through-hole into the glue-feeding grooves of the two cover plates, and finally through the two grooves into the other through-hole and the inner and outer right-angled surfaces of the corner bracket body. When the other... When glue overflows from the glue injection expansion screws in the glue injection groove, it can be determined that the glue injection amount is up to standard, thus accurately judging the glue injection time and avoiding incomplete or wasted glue injection. Furthermore, during the glue injection process, the glue injection expansion screws also expand. Since both corner bracket cover plates have three contact points with the glue injection expansion screws, the two corner bracket cover plates expand evenly in a direction perpendicular to the end face of the corner bracket body. This ensures uniform expansion of the two corner bracket cover plates, allowing for better fit and fixation with the profile, avoiding uneven expansion that could lead to insufficient fit between the corner bracket cover plates and the profile. Moreover, by setting guide ribs in the diagonal grooves of the glue channel, when the corner bracket cover plates are assembled with the profile, the expansion of the corner bracket cover plates causes the guide ribs to engage with the corresponding recesses on the profile, further improving the connection strength between the corner bracket cover plates and the profile.

[0030] See also Figures 1 to 6This utility model embodiment provides a three-body multifunctional corner code, including a corner code body 10 and corner code cover plates 20 symmetrically arranged on both end faces of the corner code body 10. The corner code body 10 has two symmetrical glue injection grooves 11 through its two end faces. The outer right-angled surface of the corner code body 10 is provided with screw through holes 12 that communicate with the glue injection grooves 11. Glue injection expansion screws 30 are inserted into each of the two screw through holes 12. The end faces of the two corner code cover plates 20 away from the corner code body 10 are respectively provided with glue-flowing grooves 21 that communicate with the two glue injection grooves 11 and the inner and outer right-angled surfaces of the corner code body 10. Each corner code cover plate 20 is provided with a first abutting member 22 and a second abutting member 23 that abut against the two glue injection expansion screws 30. The first abutting member 22 has one abutting point with the glue injection expansion screw 30, and the second abutting member 23 has two abutting points with the glue injection expansion screw 30.
[0031] Specifically, in this embodiment, the first abutting member 22 is inserted into the glue injection groove 11 and abuts against the glue injection expansion screw 30. Additionally, the outer right-angled surface of the corner bracket body 10 is recessed inward at the screw through hole 12 to form a recessed portion 14 penetrating both ends of the corner bracket body 10. The second abutting member 23 is inserted into the recessed portion 14 and abuts against the glue injection expansion screw 30. In this embodiment, the second abutting member 23 has a U-shaped structure, with both ends abutting against the glue injection expansion screw 30.
[0032] Furthermore, in this embodiment, the corner code cover plate 20 is provided with glue injection through holes 25 at the positions of the two glue injection through slots 11 respectively, and the glue flow groove 21 includes a diagonal groove 26 along the diagonal line of the corner code cover plate 20 and a right-angle groove 27 connecting the two glue injection through holes 25. The diagonal groove 26 connects the inner glue flow channel 15 and the outer glue flow channel 16 respectively.
[0033] In this embodiment, guide ribs 28 are provided in the diagonal groove 26, and the guide ribs 28 are used to position and cooperate with the profile. Specifically, in this embodiment, several guide ribs 28 are linearly distributed along the diagonal direction of the diagonal groove 26. The structure composed of several guide ribs 28 arranged in a straight line can play a role similar to a valve, controlling the flow direction and synchronicity of the glue. During glue injection, when glue overflows from the hole of the glue injection expansion screw 30, the several guide ribs 28 can ensure that the top of the corner bracket cover plate 20 is also filled with glue at the same time, which can effectively prevent the glue injection from stopping before the top is filled with glue. In addition, when the corner bracket cover plate 20 expands, its stress is closer to the center of the splice seam of the two profiles, resulting in a better leveling effect.
[0034] In addition, in this embodiment, the corner code body 10 has several positioning slots 13 extending through its two ends, and the two corner code cover plates 20 are respectively provided with positioning ribs 24 that are inserted into the several positioning slots 13.
[0035] Therefore, this utility model provides two through-holes 11 for injecting glue into the corner bracket body 10, and screw through-holes 12 communicating with the two through-holes 11 are provided on the outer right-angled surface of the corner bracket body 10, so that the glue-injecting expansion screws 30 can be inserted into the through-holes 11. Furthermore, glue-feeding grooves 21 communicating with the two through-holes 11 are provided on the two corner bracket cover plates 20 respectively, and each corner bracket cover plate 20 is provided with a first abutment that abuts against the two glue-injecting expansion screws 30. The first abutment 22 and the second abutment 23 are connected, making three contact points between the first abutment 22 and the second abutment 23 and the glue injection expansion screw 30. Thus, when the user injects glue from one of the glue injection expansion screws 30, the glue enters from that screw into the adjacent glue injection channel 11, and then flows along the glue injection channel 11 into the glue-feeding grooves 21 of the two corner bracket cover plates 20, and then through the two glue-feeding grooves 21 into the other glue injection channel 11 and the inner part of the corner bracket body 10. On the outer right-angled surface, when glue overflows from the glue-filling expansion screw 30 in the other glue-filling groove 11, it can be determined that the glue filling amount is up to standard, thus accurately determining the glue filling time and avoiding incomplete filling or glue waste. Furthermore, during the glue filling process, the glue-filling expansion screw 30 also expands. Since the contact points between the two corner bracket cover plates 20 and the glue-filling expansion screw 30 are both three points, the two corner bracket cover plates 20 expand uniformly in a direction perpendicular to the end face of the corner bracket body 10. The expansion of the corner bracket cover plates 20 ensures uniform expansion, allowing for better fit and fixation with the profile and preventing insufficient fit due to uneven expansion. Furthermore, by providing guide ribs 28 in the diagonal grooves 26 of the adhesive groove 21, the expansion of the corner bracket cover plates 20 during assembly with the profile drives the guide ribs 28 to engage with the corresponding recesses on the profile, further enhancing the connection strength between the corner bracket cover plates 20 and the profile.
[0036] In addition to using glue-injected expansion screws 30, the corner brackets of this utility model can also use solid screws with glue injection holes. For example... Figure 7 and Figure 8As shown, the corner bracket body 10 can also be perforated by using a corner-bumping method. For example, the two outer right-angled surfaces of the corner bracket body 10 can be perforated using a conventional corner bracket perforation process, so that through holes for glue injection can be opened on the outer surfaces of the two glue injection slots 11 of the corner bracket body 10. In this way, the through holes opened by the corner-bumping process can be used for normal glue injection. That is to say, the corner-bumping process eliminates the need for glue injection expansion screws 30. By using three different methods, the adaptability of the corner bracket of this utility model is enhanced.
[0037] like Figure 9 As shown, in some embodiments of this utility model, the width (axial thickness) of the corner bracket body 10 can be other thicknesses of different dimensions. This changes the lengths of the first abutting member 22 and the second abutting member 23 on the two corner bracket cover plates 20. For example, during processing, the first abutting member 22 and the second abutting member 23 on the corner bracket cover plate 20 can be directly cut without complex and cumbersome cutting processes to accommodate the glue-injection expansion screws 30 on the corner bracket body 10. Further, as... Figure 10 As shown, the position of the glue-injection expansion screw 30 on the corner bracket body 10 can be placed not in the middle, but near the lower end of the corner bracket body 10. This allows for an adaptively longer design for the first abutment member 22 and the second abutment member 23 of the upper corner bracket cover plate 20, while the lengths of the first abutment member 22 and the second abutment member 23 of the lower corner bracket cover plate 20 are adaptively shortened. In practice, only one mold is needed; the user can cut different lengths according to the actual thickness requirements, saving mold costs and cutting difficulty while still ensuring the stability of three-point contact. In other words, the width of the overall corner bracket of this invention can be adjusted according to actual conditions.
[0038] Furthermore, the overall material of this utility model can be aluminum alloy, or other materials such as plastic, and is not limited to aluminum alloy. The expansion screw can be hollow or solid.
[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the three-body multifunctional corner code of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
