Description

Technical Field

[0001] This utility model relates to the field of retractable canopy, and in particular to a connection structure between the canopy and the wall base. Background Technology

[0002] Typically, when installing a retractable awning, the wall mount is first installed at the appropriate location, and then the awning is fixed to the wall mount. This is the traditional installation method. Figure 1 As shown, a T-slot is set on the cover, and an iron plate with a threaded hole is placed inside it. The wall base plate is attached to the cover and aligned with the threaded hole on the iron plate. It is then tightened with screws to complete the installation.

[0003] With this installation method, the iron plate can slide freely within the T-slot, making installation very inconvenient. Furthermore, it is difficult to align the screws with the threaded holes when tightening the screws, resulting in troublesome and time-consuming installation. Summary of the Invention

[0004] Based on this, this application provides a connection structure between the cover and the wall base to solve the above-mentioned technical problems.

[0006] In the above technical solution, the mounting groove is further provided with an opening that matches the T-shaped nut at the first angle, and the width of the opening is consistent with that of the limiting groove.

[0007] In the above technical solution, the mounting groove is further provided with two sets of limiting ribs at the bottom of the opposite side of the opening, which are aligned with and parallel to the opening; the limiting groove formed by the two sets of limiting ribs is used to accommodate the screw; the limiting ribs restrict the T-nut from disengaging from the screw.

[0008] In the above technical solution, the T-nut further includes a main body and a limiting layer located at the lower part of the main body. The limiting layer is used to limit the maximum angle that the T-nut can rotate after entering the mounting groove.

[0009] In the above technical solution, the T-nut is further provided with a threaded hole at its center, and the limiting layer is composed of two symmetrical chamfers and right angles, with the center of the threaded hole as the center of symmetry. The radius of the chamfer is greater than half the width of the T-nut at the first angle.

[0010] In the above technical solution, a first hook is provided at the top of the wall base, and an installation plate is provided at the bottom and on one side of the cover. The limiting groove is provided on the installation plate, and the screw is screwed into the installation groove from below the installation plate, through the installation plate and the T-nut.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0026] Reference Figure 1-10 As shown, the connection structure between the cover and the wall base includes a cover 1 and a plurality of wall bases 2 disposed along the length of the cover 1. The cover 1 has a mounting groove 3 disposed along its length. The wall base 2 is provided with at least one fastening component, which includes a T-nut 4 and a screw 5. The wall base 2 is provided with a limiting groove 6 for accommodating the T-nut 4 at a first angle. The screw 5 rotates in a first direction to disengage the T-nut 4 from the limiting groove 6 and into the mounting groove 3, and rotates in a second direction to fix the T-nut 4 at a second angle within the mounting groove 3.

[0027] The mounting groove 3 is an inverted T-shaped cavity with an opening 7 on its lower surface. The width of the opening 7 matches the T-shaped nut 4 at a first angle, allowing the T-shaped nut 4 at the first angle to enter the mounting groove 3.

[0028] Meanwhile, two sets of limiting ribs 8 are provided on the bottom surface of the opposite side of the opening 7 of the mounting groove 3. The limiting ribs 8 are aligned with the opening 7, and the inner distance between the two sets of limiting ribs 8 is slightly smaller than the width of the opening 7, which matches the stud diameter of the screw 5, and is used to accommodate the screw 5. At the same time, the limiting ribs 8 can also be used to restrict the T-nut 4 from disengaging from the screw 5, and play a supporting role for the T-nut 4.

[0029] To prevent the T-nut 4 from rotating excessively, the T-nut 4 includes a main body 41 and a limiting layer 42 located at the lower part of the main body 41. The main body 41 is in the shape of an isosceles trapezoid, and the limiting layer 42 is located at the center of the bottom surface. When the screw 5 is turned a certain number of turns at a first angle, the T-nut 4 can disengage from the limiting groove 6. When the T-nut 4 abuts against the limiting rib 8, the limiting layer 42 is aligned with the groove wall of the opening 7, which limits the rotation in the first direction and unlocks the function of rotating in the second direction. It can also determine the maximum angle of rotation of the T-nut 4 in the second direction.

[0030] A fully penetrating threaded hole is provided at the center of the T-nut 4. The limiting layer 42 is composed of two symmetrical chamfers 421 and right angles 422, with the threaded hole as the center of symmetry. Preferably, the radius of the chamfer 421 is half the width of the T-nut 4. This setting can ensure that the T-nut 4 will not get stuck when it rotates.

[0031] To facilitate the easy and quick installation of the cover 1 on the wall base 2, a first hook 9 is provided on the top of the wall base 2. The first hook 9 is L-shaped. A mounting plate 10 is provided vertically on the wall base 2 near the bottom and on the side close to the cover 1. A limiting groove 6 is provided on the upper surface of the mounting plate 10. A T-nut 4 is placed in the limiting groove 6 at a first angle. A screw 5 passes through the mounting plate 10 and the T-nut 4 from below. The T-nut 4 is locked in the limiting groove 6.

[0032] A fixed arm seat 11 is provided on the cover 1. Part of the arm seat 11 is located outside the cover 1. An inverted L-shaped part is provided on the top of the arm seat 11 and on the side close to the wall seat 2, forming a hook groove with the body, so that the first hook 9 can be inserted into the second hook 12.

[0033] An opening 13 is provided at the lower part of the arm seat 11. Part of the cover 1 is placed in the opening 13 and fasteners are provided to fix it in the opening 13. The mounting groove 3 on the cover 1 faces downward and the mounting plate 10 fits into the mounting groove 3 so that the mounting groove 3 is aligned with the limiting groove 6.

[0034] The working process of this utility model is as follows: In the initial state, the screw 5 is tightened and the T-nut 4 is fixedly placed in the limiting groove 6. First, it is rotated in the first direction, which is counterclockwise, to push the screw 5 upward. At this time, the main body 41 of the T-nut 4 is locked with the groove wall of the limiting groove 6, and the screw 5 can be partially screwed downward. Then, the screw 5 and the T-nut 4 are fixed against the limiting rib 8 again. At this time, the limiting layer 42 is aligned with the groove wall of the opening 7. Then, the screw 5 is rotated again in the second direction (clockwise). The T-nut 4 rotates from the first angle shape to the second angle shape. Restricted by the right angle 422, the T-nut 4 can no longer rotate, and the screw 5 is tightened at the same time.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
