Description

Technical Field

[0001] This utility model relates to the field of hardware door and window technology, and in particular to a quick-install adjustable connection device. Background Technology

[0002] In the door and window industry, due to deviations in the cutting dimensions of door and window profiles, the opening dimensions of mating parts, and the opening dimensions of transmission rods, these cumulative assembly deviations prevent corner joints from functioning properly, leading to malfunctions in door and window operation. Furthermore, the high precision requirements for the machining of mating dimensions between various components significantly increase manufacturing costs. To address these issues, a quick-connect and adjustable functional structure is incorporated at the corner joint connection point, thus resolving the aforementioned problems. Announcement No. CN205153905U discloses a multi-purpose stainless steel door and window corner bracket, including a 90° bent outer cover and a corner transmission mechanism disposed inside the outer cover. The outer cover is cold-bent from stainless steel strip. The corner transmission mechanism includes a first connecting mechanism, a transmission belt, and a second connecting mechanism, all made of stainless steel. The upper end of the transmission belt is connected to the first connecting mechanism, and the lower end of the transmission belt is connected to the second connecting mechanism. The first connecting mechanism is slidably connected to the horizontal part of the outer cover, and the second connecting mechanism is slidably connected to the vertical part of the outer cover. The first connecting mechanism is used to connect the diagonal tie rod assembly in a European standard aluminum alloy window inward opening and bottom-hung system or a U-shaped groove PVC window inward opening and bottom-hung system. The second connecting mechanism is used to connect the inward opening transmission rod assembly in a European standard aluminum alloy window inward opening and bottom-hung system or a U-shaped groove PVC window inward opening and bottom-hung system. In this corner bracket, the distance between the transmission rod and the corner bracket is not adjustable, making it difficult to cover deviations that occur during the assembly of the door / window and the corner bracket. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-installation adjustable connection device with a stable structure and reduced production costs.

[0004] To achieve the above objectives, the present invention provides the following solution: a quick-install adjustable connecting device, comprising a corner joint, a transmission rod, an adjusting block, and a fastening screw. The corner joint includes a connecting rod with a vertically penetrating adjusting groove extending along the length of the connecting rod. A first anti-slip part is formed on the bottom surface of the connecting rod, and a second anti-slip part is formed on the top of the adjusting block. When the connecting rod and the adjusting block are vertically aligned, the first and second anti-slip parts engage with each other to restrict the relative movement of the connecting rod and the adjusting block. The fastening screw passes downward through the adjusting groove and the adjusting block in sequence and then connects to the transmission rod.

[0005] The beneficial effects of this utility model are as follows: The device allows for rapid overall connection and assembly. By incorporating a corner unit, transmission rod, adjusting block, and fastening screws, assembly is achieved simply by aligning the adjusting block with the connecting rod and transmission rod of the corner unit. The connecting rod, adjusting block, and transmission rod are then connected using the fastening screws, thus enabling rapid overall connection and assembly. Furthermore, after assembly, the first anti-slip part of the connecting rod and the second anti-slip part of the adjusting block engage with each other, restricting relative movement between the connecting rod and the adjusting block and ensuring a stable overall connection. Simultaneously, by setting an adjustment groove and adjusting the tightness of the fastening screws, the distance between the transmission rod and the corner unit can be adjusted. This can better cover deviations caused by material cutting and cumulative assembly of doors, windows, and transmission rods, preventing products from failing to fit properly during installation. It also reduces the processing precision required by cutting equipment, thereby lowering manufacturing costs and reducing the product defect rate.

[0006] Furthermore, the connecting rod has a mounting groove at its top, and an adjustment groove is formed at the center of the mounting groove, wherein the cross-sectional area of ​​the mounting groove is larger than the cross-sectional area of ​​the adjustment groove. With the above structure, when the fastening screw is placed on the connecting rod, the mounting groove supports the fastening screw, preventing the fastening screw from completely passing through the connecting rod.

[0007] Furthermore, the top surface of the connecting rod is formed with two adjustment scales, which extend along the length of the connecting rod, and the two adjustment scales are located on the left and right sides of the mounting groove, respectively. With the above structure, this invention can accurately display the position of the fastening screw, enabling precise adjustment of the position of the adjusting block.

[0008] Furthermore, the top of the transmission rod has a fixing groove, and the bottom of the adjusting block has a fixing block formed therein. When the adjusting block is set on the transmission rod, the fixing block is inserted downward into the fixing groove.

[0009] Furthermore, the adjusting block has a connecting hole in the middle, which vertically penetrates the adjusting block and the fixing block. The fastening screw passes through the adjusting groove and the connecting hole in sequence and then connects to the transmission rod.

[0010] Furthermore, the first anti-slip part has a rack and pinion structure, and the second anti-slip part has a rack and pinion structure. When the connecting rod and the adjusting block are aligned vertically, the first anti-slip part and the second anti-slip part mesh with each other.

[0011] Furthermore, the connecting rod is bent upward in the middle to form a connecting part, and a connecting groove is opened on the bottom surface of the connecting part. The connecting groove is used to install the adjusting block. The bottom surface of the connecting groove is formed with the first anti-slip part. When the adjusting block is placed in the connecting groove, the bottom surface of the adjusting block is flush with the bottom surface of the connecting part.

[0012] Furthermore, the connecting rod and the connecting part together form a receiving groove, and the end of the transmission rod enters the receiving groove. When the adjusting block is connected to the transmission rod, the bottom surface of the transmission rod is flush with the bottom surface of the connecting rod. Attached Figure Description

[0025] See appendix Figure 1 To be continued Figure 9 As shown, a quick-install adjustable connection device includes a corner bracket 1, a transmission rod 3, an adjusting block 2, and a fastening screw 4. The corner bracket 1 includes a connecting rod 11 with an adjusting groove 13 extending vertically through it. The adjusting groove 13 extends along the length of the connecting rod 11. A first anti-slip part 14 is formed on the bottom surface of the connecting rod 11, and a second anti-slip part 21 is formed on the top of the adjusting block 2. When the connecting rod 11 and the adjusting block 2 are aligned vertically, the first anti-slip part 14 and the second anti-slip part 21 engage with each other to restrict the relative movement of the connecting rod 11 and the adjusting block 2. The fastening screw 4 passes downward through the adjusting groove 13 and the adjusting block 2 in sequence and then connects to the transmission rod 3.

[0026] In this embodiment, the top of the connecting rod 11 has a mounting groove 121, and the center of the mounting groove 121 has an adjustment groove 13. The cross-sectional area of ​​the mounting groove 121 is larger than the cross-sectional area of ​​the adjustment groove 13. The top surface of the connecting rod 11 has two adjustment scales 122, which extend along the length of the connecting rod 11. The two adjustment scales 122 are located on the left and right sides of the mounting groove 121, respectively.

[0027] In this embodiment, the top of the transmission rod 3 has a fixing groove 31, and the bottom of the adjusting block 2 has a fixing block 22. When the adjusting block 2 is set on the transmission rod 3, the fixing block 22 is inserted downward into the fixing groove 31. The middle of the adjusting block 2 has a connecting hole 23, which vertically passes through the adjusting block 2 and the fixing block 22. The fastening screw 4 passes through the adjusting groove 13 and the connecting hole 23 in sequence and is then connected to the transmission rod 3.

[0028] In this embodiment, the first anti-slip part 14 has a rack-and-pinion structure, and the second anti-slip part 21 has a rack-and-pinion structure. When the connecting rod 11 and the adjusting block 2 are connected vertically, the first anti-slip part 14 and the second anti-slip part 21 mesh with each other.

[0029] In this embodiment, the middle part of the connecting rod 11 is bent upward to form a connecting part 12. The bottom surface of the connecting part 12 has a connecting groove 123 for installing the adjusting block 2. The bottom surface of the connecting groove 123 is formed with a first anti-slip part 14. When the adjusting block 2 is placed in the connecting groove 123, the bottom surface of the adjusting block 2 is flush with the bottom surface of the connecting part 12. The connecting hole 23 is a round hole, and the fixing block 22 is a cylindrical structure.

[0030] In this embodiment, the connecting rod 11 and the connecting part 12 together form a receiving groove 15. The end of the transmission rod 3 enters the receiving groove 15. When the adjusting block 2 is connected to the transmission rod 3, the bottom surface of the transmission rod 3 is flush with the bottom surface of the connecting rod 11.

[0031] In this embodiment, the specific assembly process is as follows: the adjusting block 2 is inserted upward into the connecting groove 123 of the connecting part 12, and the first anti-slip part 14 and the second anti-slip part 21 are aligned vertically and mesh with each other. Then, the transmission rod 3 is aligned with the adjusting block 2, so that the fixing block 22 of the adjusting block 2 enters the fixing groove 31. After the fastening screw 4 is set in the mounting groove 121, the fastening screw 4 passes through the adjusting groove 13 and the connecting hole 23 in sequence and is connected to the transmission rod 3 to achieve rapid assembly of the whole. At this time, the adjusting block 2 is in the initial state and the fastening screw 4 is located in the middle of the adjusting groove 13.

[0032] When the transmission rod 3 needs to move closer to the connecting rod 11, loosen the fastening screw 4 to disengage the first anti-slip part 14 from the second anti-slip part 21. Then, move the adjusting block 2 and the transmission rod 3 forward to the connecting rod 11, and adjust the scale 122 until the adjusting block 2 and the transmission rod 3 are close to the set position. Then, tighten the fastening screw 4 again to re-engage the first anti-slip part 14 and the second anti-slip part 21. This is the negative adjustment state.

[0033] When it is necessary for the transmission rod 3 to move away from the connecting rod 11, loosen the fastening screw 4 to disengage the first anti-slip part 14 from the second anti-slip part 21. Then, move the adjusting block 2 and the transmission rod 3 forward to approach the connecting rod 11, and adjust the scale 122 until the adjusting block 2 and the transmission rod 3 move away from the set position. Then, tighten the fastening screw 4 again to re-engage the first anti-slip part 14 and the second anti-slip part 21. This is the positive adjustment state.

[0034] During the manufacturing process of doors and windows, there are material cutting deviations and cumulative assembly deviations. This is especially true for window types that use corner bracket 1, where the requirements for profile cutting and transmission rod cutting are high. If the manufacturing deviation is too large, it will cause the locking rod and corner bracket to not be properly assembled. This embodiment solves this problem by setting a hanging structure that can be adjusted in both positive and negative directions on the corner bracket 1, thereby greatly reducing manufacturing costs and the defective scrap rate of products.

[0035] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
