Description

Technical Field

[0001] The invention relates to a door, in particular to a hinge seat and a door frame. Background Art

[0002] like Figure 4 and Figure 5 As shown, in the prior art, to achieve a hidden hinge seat, a notch is usually punched in the door frame body 10 to form an installation opening 50 on the door frame body 10. The hinge seat 20 is embedded and welded into the installation opening 50. Then, waterproof glue is applied to the joint between the hinge seat 20 and the door frame body 10. The hinge 30 is connected to the hinge seat 20 via the hinge shaft 40. With this solution, the hinge seat and the door frame body are connected to form an integral structure, creating the effect of the hinge seat being hidden in the door frame body. However, this solution has the following technical problems:

[0003] The hinge base is made of sheet metal that is punched and bent. To ensure that the hinge base fits smoothly into the mounting opening, it is usually slightly smaller than the mounting opening. This results in a larger gap between the hinge base and the mounting opening, especially at the corners. This allows the waterproof adhesive to easily leak out of the gap, which can contaminate the product, resulting in poor waterproof performance and appearance. Furthermore, the weld seam is easily exposed at the gap, which in turn leads to a poor product appearance.

[0004] Since the hinge seat is embedded in the installation opening, the relative position between the hinge seat and the door frame body is difficult to ensure during welding, resulting in problems such as great welding difficulty, low processing efficiency, difficulty in ensuring product quality, and poor product consistency.

[0027] like Figure 1 The hinge base 1 shown in the figure includes a base plate 101, a first ear 102, a second ear 104, two first extensions 106 and two second extensions 108. The first ear 102 is folded upward from the middle part of the left end of the base plate 101 in the front-to-back direction. The two first extensions 106 extend to the left from the left end of the base plate 101 from the front and rear parts of the left end of the base plate 101, respectively. The two first extensions 106 are respectively located on the front and rear sides of the first ear 102. A first limiting groove 107 is formed between the two second extensions 108 and the second extensions 108. The second ear 104 is folded upward from the middle part of the right end of the bottom plate 101 in the front-to-back direction. Two second extensions 108 extend rightward from the right end of the bottom plate 101 from the front and rear parts of the right end of the bottom plate 101, respectively. The two second extensions 108 are respectively located at the front and rear sides of the second ear 104. A second limiting groove 109 is formed between the two second extensions 108. Both the first ear 102 and the second ear 104 are provided with connecting holes for connecting the hinge shaft 3.

[0028] By adopting the above-mentioned technical solution, by setting two first extensions 106 and two second extensions 108, on the first hand, a first limiting groove 107 and a second limiting groove 109 can be formed. By using the first limiting groove 107 and the second limiting groove 109 to cooperate with the structure on the door frame body 2, the relative position between the hinge seat 1 and the door frame body 2 can be limited, which is beneficial to reducing the difficulty of welding, improving welding efficiency, ensuring welding accuracy and ensuring product consistency; on the second hand, the two first extensions 106 and the two second extensions 108 are set to cover the corner part of the installation port on the door frame body 2, which can effectively reduce or even eliminate the leakage of waterproof glue from the corner part of the fitting point between the installation port and the hinge seat 1, and can prevent the waterproof glue from contaminating the outer surface of the door frame, which is beneficial to improving the gluing quality of the waterproof glue to ensure the waterproof performance of the connection part between the hinge seat 1 and the door frame body 2.

[0029] In some embodiments, a first through hole 103 for connecting to the hinge shaft 3 is provided on the first lug 102 , and a second through hole 105 for connecting to the hinge shaft 3 is provided on the second lug 104 .

[0030] In some embodiments, the first lug 102 is perpendicular to the bottom plate 101 , and the second lug 104 is perpendicular to the bottom plate 101 .

[0031] In some embodiments, the width of the first limiting groove 107 in the front-to-back direction is consistent with the width of the first support ear 102 in the front-to-back direction, and the width of the second limiting groove 109 in the front-to-back direction is consistent with the width of the second support ear 104 in the front-to-back direction. Using the above-described technical solution, after blanking and punching, the hinge seat 1 described above can be obtained through a single stamping and bending process, which is easy to process. Furthermore, the formed first support ear 102 can effectively cover the right end of the first rib 202 of the door frame body 2, and the formed second support ear 104 can effectively cover the left end of the second rib 203 of the door frame body 2.

[0032] In some embodiments, the hinge base 1 is an integral piece formed by punching and bending a metal plate. By properly configuring the structure of the hinge base 1, the hinge base 1 can be formed by punching and bending a metal plate, which is easy to manufacture.

[0033] In some embodiments, the bottom plate 101 is a rectangular plate structure. Using the above technical solution, the front edge and the rear edge of the bottom plate 101 can be supported on the side plate 201 of the door frame.

[0034] The present invention also provides a door frame, such as Figure 2 and Figure 3 As shown, the door frame includes a door frame body 2 and any one of the hinge seats 1 described above, the door frame body 2 includes a side panel 201, a first rib 202 protruding upward from the side panel 201, and a second rib 203 protruding upward from the side panel 201, the length direction of the first rib 202 and the length direction of the second rib 203 are both arranged in the left and right directions, a first opening 204 is provided on the side panel 201, the first rib 202 is located on the left side of the first opening 204, a second opening 205 is provided at the right end of the first rib 202, and the second rib 203 is provided at the right end. 03 is located on the right side of the first opening 204, and a third opening is provided at the left end of the second rib 203. The first opening 204, the second opening 205 and the third opening are connected to form an installation opening for installing the hinge seat 1. The bottom plate 101 is supported downward on the side plate 201. The bottom plate 101 covers the first opening 204, the first support ear 102 covers the second opening 205, and the second support ear 104 covers the third opening. The first limiting groove is clamped on the outer side of the right end portion of the first rib 202, and the second limiting groove is clamped on the outer side of the left end portion of the second rib 203.

[0035] By adopting the above-mentioned technical solution, the bottom plate 101 is supported downward on the side plate 201, the first limiting groove 107 is stuck on the outer side of the right end of the first rib 202, and the second limiting groove is stuck on the outer side of the left end of the second rib 203, thereby limiting the relative position between the hinge seat 1 and the door frame body 2, which is conducive to reducing the difficulty of welding, improving welding efficiency, ensuring welding accuracy and ensuring product consistency; the two first protrusions 106 can effectively block the front and rear ends of the corner part between the first opening 204 and the second opening 205, and the two second protrusions 108 can effectively block the front and rear ends of the corner part between the first opening 204 and the third opening, which can effectively reduce or even eliminate the leakage of waterproof glue from the corner part of the fitting between the installation port and the hinge seat 1, and can prevent the waterproof glue from contaminating the outer surface of the door frame, which is conducive to improving the quality of the waterproof glue to ensure the waterproof performance of the connection part between the hinge seat 1 and the door frame body 2.

[0036] In some embodiments, the front edge of the bottom plate 101 overlaps the upper side of the side plate 201, and the rear edge of the bottom plate 101 overlaps the upper side of the side plate 201. In a specific implementation, the side plate 201 has a first edge portion arranged in front of the first opening 204 and a second edge portion arranged behind the first opening 204. The front edge of the bottom plate 101 overlaps the upper side of the first edge portion, and the rear edge of the bottom plate 101 overlaps the second edge portion. The above-mentioned solution provides convenience for fixing the hinge seat 1 and the door frame body 2 by spot welding, and can form a double-layer welded structure; the double-layer welded structure can strengthen the structure at the first opening 204, which is beneficial to improving product quality; when applying waterproof glue on the inner side of the door frame, since the front edge and the rear edge of the bottom plate 101 are overlapped on the upper side of the side plate 201, it can effectively reduce or even eliminate the leakage of waterproof glue from the fitting point between the first opening 204 and the bottom plate 101, and can prevent the waterproof glue from contaminating the outer surface of the door frame, which is beneficial to improving the gluing quality of the waterproof glue to ensure the waterproof performance of the connection between the hinge seat 1 and the door frame body 2.

[0037] In some embodiments, the front edge of the first ear 102 is connected to the right side of the right edge of the front side wall of the first rib 202, the rear edge of the first ear 102 is connected to the right side of the right edge of the rear side wall of the first rib 202, and the upper edge of the first ear 102 is connected to the right side of the right edge of the upper side wall of the first rib 202; the front edge of the second ear 104 is connected to the left side of the left edge of the front side wall of the second rib 203, the rear edge of the second ear 104 is connected to the left side of the left edge of the rear side wall of the second rib 203, and the upper edge of the second ear 104 is connected to the left side of the left edge of the upper side wall of the second rib 203. By adopting the above technical solution, the first ear 102 can better cover the right end of the first rib 202, and the second ear 104 can better cover the left end of the second rib 203. When applying waterproof glue on the inner side of the door frame, it can effectively reduce or even eliminate the leakage of waterproof glue from the fitting point between the first ear 102 and the second opening 205, and can effectively reduce or even eliminate the leakage of waterproof glue from the fitting point between the second ear 104 and the third opening, and can prevent the waterproof glue from contaminating the outer surface of the door frame, which is conducive to improving the gluing quality of the waterproof glue to ensure the waterproof performance of the connection part between the hinge seat 1 and the door frame body 2.

[0038] In some embodiments, both first extensions 106 are stacked on the upper side of the side panel 201, and both second extensions 108 are stacked on the upper side of the side panel 201. With the above technical solution, the first extensions 106 and the side panel 201 form a double-layer stacked structure, and the second extensions 108 and the side panel 201 form a double-layer stacked structure, which can better prevent the waterproof glue from leaking out, and can set welding points in the double-layer stacked structure to improve welding strength.

[0039] In some embodiments, the door frame further includes a hinge shaft 3, a hinge plate 4 and a sleeve 5. The left and right ends of the hinge shaft 3 are respectively connected to the first ear 102 and the second ear 104. The hinge hole on the hinge plate 4 cooperates with the hinge shaft 3. The sleeve 5 is supported between the hinge hole of the hinge plate 4 and the hinge shaft 3. The hinge plate 4 can rotate around the hinge shaft 3. The hinge plate 4 is used to connect to the door leaf.

[0040] In some embodiments, the hinge base 1 is fixedly connected to the door frame body 2 by welding. In specific implementation, the welding method can be spot welding. The double-layer stacked structure formed above provides convenience for spot welding, which helps to reduce the difficulty of welding.

[0041] By adopting any of the door frames described above, by reasonably setting the structure of the hinge seat 1, the fitting gap between the hinge seat 1 and the door frame body 2 can be reduced and the aesthetic appearance of the door frame can be improved. When applying waterproof glue on the inner side of the door frame, the smaller and more curved gaps can ensure that the waterproof glue can fill the gaps to play a waterproof role without overflowing and polluting the product. The quality of the waterproof glue can be guaranteed, thereby greatly improving the waterproof quality and appearance quality of the product, and can ensure the sealing performance of the hinge seat 1, and no leakage or seepage will occur even in strong winds and heavy rain.
