Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a frame connection structure. Background Technology

[0002] Currently, door and window frame components generally adopt an aluminum alloy profile splicing structure, which typically consists of vertical and horizontal frames connected at right angles to form the main frame. In existing technology, the connection between adjacent frames mainly adopts the following method: processing mating interfaces at the ends of the profiles, and using a composite connection method of bolt fastening combined with sealant bonding.

[0003] However, the above-mentioned traditional connection methods have significant technical defects: First, due to insufficient processing precision, the profile connection surface is prone to assembly gaps. Under changes in ambient temperature and humidity and structural loads, the connection part is prone to plastic deformation, leading to instability of the frame geometry. Second, the metal corner brackets added to compensate for insufficient structural strength require a multi-point positioning installation process, which presents technical difficulties such as difficulty in unifying the assembly reference surface and strict requirements for the fastening sequence, thus complicating the installation process and increasing installation time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a frame connection structure that simplifies the installation process and reduces installation time.

[0005] To solve the above-mentioned technical problems, this utility model provides a frame connection structure, including a vertical frame, a horizontal frame, a mounting base, and a first locking bolt. The vertical frame has an inlay groove with an opening facing forward. The mounting base is placed in the inlay groove and located at the end of the vertical frame and is threadedly connected to the vertical frame. The horizontal frame has a connecting groove with an opening facing left. The mounting base has a connecting arm that extends forward and is used to insert into the connecting groove. The connecting arm has a threaded through hole for threaded connection with the first locking bolt. The first locking bolt is used for threaded connection with the threaded through hole and abuts against the inner wall of the connecting groove.

[0006] As an improvement to the above solution, the lower side of the connecting arm is provided with a downward protruding locking head, and the lower side of the connecting groove is provided with a support groove that matches the locking head.

[0007] As an improvement to the above solution, the upper side of the connecting arm is provided with a receiving groove for accommodating the upper side of the connecting groove, and the upper side of the connecting arm coincides with the upper side of the horizontal frame.

[0008] As an improvement to the above solution, the mounting base is provided with a positioning groove for the horizontal frame to extend into, the connecting arm is fixed in the positioning groove and extends out of the front side of the vertical frame, and the upper side of the connecting arm coincides with the upper side of the mounting base.

[0009] As an improvement to the above solution, the connecting arm is provided with an inlay hole with the opening facing right, a locking nut that is fitted into the inlay hole, and a first clearance through hole with the opening facing left and communicating with the inlay hole. The first locking bolt is used to pass through the first clearance through hole and be threadedly connected to the locking nut.

[0010] As an improvement to the above solution, the frame connection structure of this utility model also includes multiple second locking bolts. The rear side of the mounting base is provided with multiple connecting threaded holes spaced vertically. The rear side of the vertical frame is provided with multiple second clearance through holes that correspond one-to-one with the multiple connecting threaded holes.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0029] like Figures 1 to 7 As shown, one embodiment of the present invention provides a frame connection structure including a vertical frame 100, a horizontal frame 200, a mounting base 300, and a first locking bolt 400. In practice, the vertical frame 100, the horizontal frame 200, and the mounting base 300 can be made of aluminum profiles or aluminum alloy and can be assembled into a frame to support doors and windows.

[0030] The vertical frame 100 has a front-facing inlay groove 110. The mounting base 300 is placed in the inlay groove 110 and located at the end of the vertical frame 100 and is threadedly connected to the vertical frame 100. In practice, when installing the mounting base 300 to the vertical frame 100, the mounting base 300 is placed into the inlay groove 110 of the vertical frame 100, and the mounting base 300 is positioned and fixedly installed at the end of the vertical frame 100 by means of threaded connection.

[0031] The horizontal frame 200 has a connecting groove 210 with its opening facing left. The mounting base 300 has a connecting arm 310 extending forward and inserted into the connecting groove 210. The connecting arm 310 has a threaded through hole 311 for threaded connection with a first locking bolt 400. The first locking bolt 400 is used to thread into the threaded through hole 311 and abuts against the inner wall of the connecting groove 210. In fact, the groove profile of the connecting groove 210 matches the profile of the connecting arm 310, so that after the connecting arm 310 is inserted into the connecting groove 210, it can only move back and forth relative to the connecting groove 210 and cannot move left and right or up and down relative to the connecting groove 210. This ensures that the relative angle between the mounting base 300 and the horizontal frame 200 is stable, which to some extent prevents deformation after the horizontal frame 200 and the connecting arm 310 are connected, and provides a positioning function for the connecting arm 310 to be installed and fixed to the horizontal frame 200. When fixing the connecting arm 310 to the horizontal frame 200, the first locking bolt 400 can be rotated and screwed into the threaded through hole 311 on the mounting base 300 using a tool until the first locking bolt 400 hits the inner wall of the connecting groove 210, so that there is an interaction force between the first locking bolt 400 and the horizontal frame 200 perpendicular to the extension direction of the connecting groove 210, which plays the role of locking the connecting arm 310 in the connecting groove 210 and preventing the connecting arm 310 from moving back and forth relative to the connecting groove 210.

[0032] The frame connection structure of this utility model consists of a vertical frame 100, a horizontal frame 200, a mounting base 300, a first locking bolt 400, an inlay groove 110, a connecting groove 210, a connecting arm 310, and a threaded through hole 311. The vertical frame 100 and the horizontal frame 200 can be installed and connected by threaded connection between the mounting base 300 and the vertical frame 100, and by threaded connection between the connecting arm 310 and the horizontal frame 200. The geometric dimensions of the frame are relatively stable after installation, and no multi-point positioning is required during installation, which simplifies the installation process and reduces installation time.

[0033] Specifically, such as Figure 2 As shown, the lower side of the connecting arm 310 preferably has a downwardly protruding locking head 312, and the lower side of the connecting groove 210 has a supporting groove 211 that matches the locking head 312. When the connecting arm 310 extends into the connecting groove 210, the locking head 312 cooperates with the connecting groove 210 to increase the contact area between the connecting arm 310 and the connecting groove 210, and improve the supporting and limiting effect of the horizontal frame 200 on the connecting arm 310, further preventing the connecting arm 310 from moving left and right relative to the connecting groove 210, so as to prevent deformation after the horizontal frame 200 and the connecting arm 310 are connected.

[0034] More specifically, the upper side of the connecting arm 310 preferably has a receiving groove 313 for accommodating the upper side of the connecting groove 210, and the upper side of the connecting arm 310 coincides with the upper side of the horizontal frame 200. In fact, as... Figure 2 , Figure 5 and Figure 7 As shown, the upper side of the connecting groove 210 is located on the frame plate that partially overlaps with the upper side of the horizontal frame 200. Therefore, the receiving groove 313 serves to accommodate part of the frame plate of the horizontal frame 200, thereby improving the matching degree between the upper side of the connecting arm 310 and the upper side of the horizontal frame 200.

[0035] Furthermore, the mounting base 300 preferably has a positioning groove for the horizontal frame 200 to extend into. The connecting arm 310 is fixed in the positioning groove and extends out from the front of the vertical frame 100, with the upper side of the connecting arm 310 overlapping with the upper side of the mounting base 300. When the horizontal frame 200 extends into the positioning groove, the connection strength between the horizontal frame 200 and the mounting base 300 is further improved, and deformation of the horizontal frame 200 relative to the mounting base 300 is further prevented. Moreover, after the relative position of the connecting arm 310 and the horizontal frame 200 is fixed, the upper side of the mounting base 300, the upper side of the connecting arm 310, and the upper side of the horizontal frame 200 overlap, reducing the impact on subsequent door and window installation.

[0036] It should be noted that the connecting arm 310 preferably has a right-facing insert hole 314, a locking nut 315 fitted into the insert hole 314, and a left-facing first clearance through hole 316 communicating with the insert hole 314. The first locking bolt 400 is used to pass through the first clearance through hole 316 and be threadedly connected to the locking nut 315. In practice, the outer contour of the locking nut 315 is hexagonal, and the insert hole 314 matches the locking nut 315, so that the locking nut 315 cannot rotate after being placed in the insert hole 314. The insert hole 314, the locking nut 315, and the first clearance through hole 316 cooperate to realize the function of the threaded through hole 311. When the threaded through hole 311 on the locking nut 315 is damaged, a new locking nut 315 can be replaced, without directly replacing the entire mounting base 300.

[0037] Specifically, the frame connection structure of this utility model preferably includes multiple second locking bolts 500. The rear side of the mounting base 300 has multiple vertically spaced connecting threaded holes 317, and the rear side of the vertical frame 100 has multiple second clearance through holes 112 corresponding one-to-one with the multiple connecting threaded holes 317. The second locking bolts 500 are used to pass through the second clearance through holes 112 and then threadedly connect with the connecting threaded holes 317. Through the cooperation of multiple sets of connecting threaded holes 317, second clearance through holes 112, and second locking bolts 500, the threaded connection and positioning of the mounting base 300 and the vertical frame 100 are achieved, ensuring the connection strength between the mounting base 300 and the vertical frame 100. The accompanying drawings of this embodiment show two sets of connecting threaded holes 317, second clearance through holes 112, and second locking bolts 500 in cooperation; the number of sets in actual applications can be modified according to specific needs.

[0038] Furthermore, the left and right ends of the opening of the inlay groove 110 are preferably provided with hooks 111 that bend inward and then backward, and the front of the left and right sides of the mounting base 300 are provided with hook grooves 320 for the hooks 111 to be engaged. In fact, the left hook 111 bends to the right and then backward, and the right hook 111 bends to the left and then backward. With the help of the two corresponding hook grooves 320, the mounting base 300 can slide up and down relative to the inlay groove 110, so as to limit the swing of the mounting base 300 relative to the vertical frame 100 and prevent deformation of the vertical frame 100 after it is connected to the mounting base 300 to a certain extent.

[0039] Furthermore, the front ends of the left and right sides of the card holder 300 are preferably provided with baffles 330 that correspond to and abut against the card hooks 111. The baffles 330 increase the contact area between the card holder 300 and the vertical frame 100, thereby improving the limiting effect of the inlay groove 110 on the card holder 300.

[0040] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
