Abstract
Description
Technical Field
[0001] The invention relates to the technical field of shower rooms, and in particular to a door frame structure with hidden hinges and a shower room. Background Art
[0002] The existing hidden hinges on the market are fixed on two metal profiles or fixed on one side of the profile and the other side of the wooden / aluminum door frame. The hinges cannot be seen from the front, and the door body with this structural hinge can be opened 90°. However, the current hidden hinges are fixed on two horizontally parallel profiles, and there is a certain gap between the two profiles, which is difficult to be completely sealed. When used in a shower room, water will flow out from the gap. In addition, the door body with hidden hinges can only rotate 90°, which has great limitations in actual use. For example, when used in a shower room, opening the door for ventilation when the shower room is not in use will cause obstruction to the user. Summary of the invention
[0003] The present invention aims to solve at least one of the above-mentioned technical problems in the related art to a certain extent. To this end, the present invention provides a door frame structure with hidden hinges.

[0034] Reference Figure 1-6A door frame structure with a hidden hinge comprises a first door frame 100 and a hidden hinge 200. The first door frame 100 is provided with a first accommodating cavity 130 penetrating a rear wall 110 and a right wall 120 thereof. The hidden hinge 200 comprises a first hinge body 210, a second hinge body 220 and a rotating shaft 230. The first hinge body 210 is provided with a hinge notch 211. The first hinge body 210 is embedded in the first accommodating cavity 130 so that the first hinge body 210 is blocked by a front wall 140 of the first door frame 100. The second hinge body 220 comprises an L-shaped connecting frame 221 and a mounting block 222. The L-shaped connecting frame 221 comprises a first connecting edge 223 and a second connecting edge 224 perpendicular to each other. The first connecting edge 22 A shaft sleeve 225 is formed at one end away from the second connection edge 224, and the mounting block 222 is connected to one end of the second connection edge 224 away from the first connection edge 223. The mounting block 222 has a mounting surface 226 for connecting with the door body, and the mounting surface 226 is perpendicular to the first connection edge 223 and faces the side where the shaft sleeve 225 is located. The shaft sleeve 225 is embedded in the hinge notch 211. The second hinge body 220 penetrates the hinge notch 211 and the shaft sleeve 225 through the rotating shaft 230 to be rotatably connected with the first hinge body 210. The second hinge body 220 can rotate 180° around the rotating shaft 230 from the first position to the second position, so that the mounting block 222 rotates from the rear of the first door frame 100 to the front of the first door frame 100. Specifically, when the second hinge body 220 is in the first position, the mounting block 222 is located at the left rear of the rotating shaft 230, and the mounting surface 226 faces to the right, so that after the mounting surface 226 is connected to the door body, the door body is arranged along the left and right sides. When the second hinge body 220 is in the second position, the mounting block 222 is located at the right front of the rotating shaft 230.
[0035] The door body connected to the mounting surface 226 is a movable door 400. When the second hinge body 220 is in the first position, the movable door 400 is in a closed state. At this time, the movable door 400 is located behind the first door frame 100. When the second hinge body 220 is in the second position, the movable door 400 is in a fully open state. At this time, the movable door 400 bypasses the first door frame 100 and reaches the front of the first door frame 100.
[0036] In some embodiments of the present invention, Figure 4As shown, it also includes a second door frame 300, and the second door frame 300 is provided with a second accommodating cavity 310 for installing a mounting block 222 and a first mounting groove 320 for installing a door body. The mounting block 222 is embedded in the second accommodating cavity 310, and a screw mounting hole 227 is opened on the mounting surface 226. The mounting block 222 is connected to the second door frame 300 by screws. The notch direction of the first mounting groove 320 is the same as the direction of the mounting surface 226. The shortest distance L1 from the axis of the rotating shaft 230 to the second door frame 300 is greater than the distance L2 from the axis of the rotating shaft 230 to the front wall 140 of the first door frame 100. The second hinge body 220 can rotate 180° around the rotating shaft 230 from the first position to the second position, so that the second door frame 300 can rotate from the rear of the first door frame 100 to the front of the first door frame 100. L1>L2 ensures that when the movable door 400 rotates to the front of the first door frame 100 , the second door frame 300 can smoothly bypass the first door frame 100 without being blocked or collided by the first door frame 100 .
[0037] In some embodiments of the present invention, the hidden hinge 200 further includes two wear-resistant gaskets 240, which are sleeved on the rotating shaft 230 and are respectively located at the upper end and the lower end of the shaft sleeve 225, and are sandwiched between the shaft sleeve 225 and the first hinge body 210. The wear-resistant gaskets 240 can reduce the noise generated by the relative rotation of the first hinge body 210 and the second hinge body 220 when the door is opened and closed.
[0038] In some embodiments of the present invention, the first hinge body 210 includes a main body 213 and two mounting plate portions 212, a hinge notch 211 is provided in the main body 213, and the two mounting plate portions 212 are respectively provided at the upper end and the lower end of the main body 213, the main body 213 is embedded in the first accommodating cavity 130, and the mounting plate portion 212 is tightly attached to the rear wall 110 or the right wall 120 of the first door frame 100, and the mounting plate portion 212 is installed on the rear wall 110 or the right wall 120 of the first door frame 100 by screws. The fixing method of the mounting plate portion 212 may vary with the size of the first door frame 100. The mounting plate portion 212 is a thin plate structure, and when the side surface of the first profile is narrow, the mounting plate portion 212 can be fixed on the surface of the rear wall 110 of the first profile, such as Fig. 9 shown.
[0039] In some embodiments of the present invention, the rear wall 110 or the right wall 120 of the first door frame 100 is partially recessed inward to form a groove that matches the mounting plate portion 212, and the mounting plate portion 212 is embedded in the groove. When the side of the first profile is wider, the mounting plate portion 212 can be embedded in the groove of the rear wall 110 or the right wall 120 of the first door frame 100, so that the mounting plate portion 212 is flush with the surface of the first door frame 100, does not occupy additional space, and only the front wall 140 of the first door frame 100 can be seen from the front, and the appearance is simple and beautiful, such as Figure 10-11 shown.
[0040] In some embodiments of the present invention, the cross section of the first door frame 100 is L-shaped, and is composed of a first frame body 150 and a second frame body 160 that are perpendicular to each other. The first frame body 150 and the second frame body 160 are an integral structure, and the second frame body 160 is located on the left side of the rear side of the first frame body 150. The first accommodating cavity 130 is provided on the first frame body 150. The second frame body 160 is provided with a second mounting groove 161 for mounting the door body, and the groove direction of the second mounting groove 161 is opposite to the groove direction of the first mounting groove 320. The second door frame 300 is located behind the first frame body 150 and to the right of the second frame body 160. The second mounting groove 161 is used to mount the fixed door 500. Further, as Figure 7 As shown, the distance L3 from the right wall 120 of the first frame 150 to the second frame 160 is greater than the width L4 of the second door frame 300 in the left-right direction, and the length L5 of the second frame 160 in the front-to-back direction is greater than the length L6 of the second door frame 300 in the front-to-back direction. From the front, the second door frame 300 is completely hidden in the first door frame 100, and only the first door frame 100 is visible, meeting the user's design requirements for a minimalist style shower room. In addition, the second frame 160 can block the gap between the movable door 400 and the first door frame 100, so that water will not flow out of the shower room.
[0041] In some embodiments of the present invention, the hidden hinge 200 further includes a first positioning member 250, which is mounted on the side wall of the hinge notch 211. When the second hinge body 220 is in the first position, the mounting block 222 is located at the left rear of the rotating shaft 230, and the second connecting edge 224 abuts against the first positioning member 250. When the movable door 400 is closed, the first positioning member 250 abuts against the second connecting edge 224, so that the movable door 400 cannot continue to rotate inward, thereby preventing the second door frame 300 from colliding with the first door frame 100.
[0042] In some embodiments of the present invention, an avoidance cut corner 228 is provided at the corner where the first connecting edge 223 and the second connecting edge 224 of the L-shaped connecting frame 221 to prevent the second hinge body 220 from being blocked by the first positioning member 250 when rotating to the second position.
[0043] In some embodiments of the present invention, the hidden hinge 200 further includes a second positioning member 260, which is mounted on the second connecting edge 224. When the second hinge body 220 is in the second position, the second positioning member 260 abuts against the first door frame 100. When the movable door 400 is opened 180°, the second positioning member 260 abuts against the right side of the first door frame 100, so that the movable door 400 cannot continue to rotate. After the movable door 400 is opened 180°, it is parallel to the fixed door 500 to prevent the movable door 400 from colliding with the fixed door 500.
