Description

Technical Field

[0001] The utility model belongs to the technical field of bathroom appliances, and particularly relates to an anti-drooping hinge and a shower room door thereof. Background Art

[0002] Due to product characteristics, deviations in accessory manufacturing, and installation errors, shower rooms with hinged doors have various assembly gaps at the beginning of installation, leaving space for the fixed glass door to sag. As a result, after long-term use, the fixed glass door will inevitably tilt and fall, causing the sealing to fail, or even the fixed glass door to grind to the ground and become unable to close, resulting in the loss of the basic function of the shower room. The currently commonly used countersink improvement solution has been found to be unable to completely avoid the misalignment between the glass hole and the hinge, and therefore cannot meet the anti-sagging function well. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an anti-droop hinge and a shower room door thereof.

[0004] The utility model adopts the following technical solutions:

[0005] An anti-droop hinge includes a movable leaf disposed on a movable glass door, a fixed leaf disposed on a fixed glass door and movably connected to the movable leaf, and two locking mechanisms for fixing the movable leaf and the fixed leaf to the movable glass door and the fixed glass door, respectively. The locking mechanism includes a positioning member disposed on the movable leaf or the fixed leaf and a locking member that cooperates with the positioning member to lock the movable leaf to the movable glass door or the fixed leaf to the fixed glass door.

[0006] The positioning piece includes a positioning lock cover arranged in the movable leaf or the fixed leaf, a positioning block embedded in the positioning lock cover and cooperating with the locking piece, and a texture structure arranged on the opposite surface of the positioning lock cover and the positioning block; the movable glass door or the fixed glass door is provided with a mounting hole for the locking piece to pass through.

[0007] Furthermore, the locking member includes a locking gasket arranged on the contact surface between the movable page and the movable glass door or the contact surface between the fixed page and the fixed glass door, a locking screw arranged in the mounting hole and cooperating with the positioning block, an inner locking sleeve and an outer locking sleeve sequentially sleeved on the outer periphery of the locking screw, and an extrusion sleeve sleeved on the outer locking sleeve that can squeeze the locking gasket.

[0008] Furthermore, the extrusion sleeve is formed with a tapered hole for the outer locking sleeve to be embedded, the lower end of the outer locking sleeve is formed with a tapered section that can be embedded in the tapered hole, the tapered section is formed with an equal-diameter hole for the inner locking sleeve to be embedded, and the lower end of the inner locking sleeve is formed with an equal-diameter section that can be embedded in the equal-diameter hole.

[0009] Furthermore, the positioning block includes a supporting section that can be supported on the positioning lock cover and an inserting section that is arranged on the supporting section and can be embedded in the positioning lock cover. The positioning lock cover is provided with an inserting hole for the inserting section to be embedded, and the inserting section is formed with a locking screw hole that cooperates with the locking screw.

[0010] Furthermore, the texture structure is composed of a plurality of concentric annular bosses.

[0011] Furthermore, the movable page includes a movable page body and a first shell embedded in the movable page body. A first positioning groove for installing a positioning piece is provided on the opposite surface of the movable page body and the movable glass door. The first shell is embedded in the movable page body to cover the first positioning groove, and a clearance hole is provided on it for the locking piece to pass through.

[0015] A shower room door comprises a movable glass door and a fixed glass door, and also comprises an anti-sagging hinge as described above and arranged between the movable glass door and the fixed glass door.

[0016] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are as follows: the present application limits the structure of the positioning part and provides a texture structure on the contact surface of the positioning lock cover and the positioning block. Through the setting of the texture structure, the friction resistance between the positioning lock cover and the positioning block is greatly increased, thereby preventing the glass door from being misaligned with the hinge and achieving the effect of anti-drooping; in addition, the structure of the locking part is further limited, and the positioning part is cooperated so that the shower door can provide an assembly gap at the beginning of installation to compensate for various production and installation deviations, and these assembly gaps can be eliminated after the installation is completed, and the anti-drooping ability of the countersunk hole scheme is further improved, and the deviation resistance is increased in the deviation trend that may cause sagging, thereby hindering the sagging of the glass door and improving the stability of the product. Among them, the traditional double-ring structure is replaced with a three-ring structure, so that the assembly method can not only continue to use the tapered hole mode but also eliminate the hole gap, thereby improving the anti-drooping ability from multiple angles.

DETAILED DESCRIPTION

[0026] The present invention is further described below through specific implementation methods.

[0027] Reference Figures 1 to 8 As shown, a shower room door comprises a movable glass door 1, a fixed glass door 2 and an anti-drooping hinge 3 arranged between the movable glass door 1 and the fixed glass door 2.

[0028] The hinge 3 includes a movable page 4 provided on the movable glass door 1, a fixed page 5 provided on the fixed glass door 2 and movably connected to the movable page 4, two locking mechanisms 6 for fixing the movable page 4 and the fixed page 5 to the movable glass door 1 and the fixed glass door 2 respectively, and a connecting member 7 provided between the fixed glass door 2 and the fixed page 5. Specifically, the locking mechanism 6 includes a positioning member 61 provided on the movable page 4 or the fixed page 5, and a locking member that cooperates with the positioning member 61 to lock the movable page 4 to the movable glass door 1 or lock the fixed page 5 to the fixed glass door 2, wherein a mounting hole 8 for the locking member 62 to pass through is provided on the movable glass door 1 or the fixed glass door 2, and a connecting hole 9 is formed on the fixed glass door 2 to cooperate with the connecting member 62.

[0029] The positioning member 61 includes a positioning lock cover 611 set in the movable page 4 or the fixed page 5, a positioning block 612 embedded in the positioning lock cover 611 and cooperating with the locking member 62, and a texture structure 613 set on the opposite surface of the positioning lock cover 611 and the positioning block 612.

[0030] The movable page 4 includes a movable page body 41 and a first shell 42 embedded in the movable page body 41, wherein a first mounting groove 43 for installing a positioning member 61 is provided on the opposite surface of the movable page body 41 and the movable glass door 1, and the first shell 42 is embedded in the movable page body 41 to cover the first positioning groove 43, and is provided with a clearance hole 44 for the locking member 62 to pass through; specifically, the movable page body 41 is formed with a connecting portion 45 movably connected to the fixed page 5, and the fixed page 5 is provided with a connecting block 51 movably connected to the connecting portion 45, and the connecting portion 45 is formed with a connecting hole 46 for the connecting block 51 to be embedded; further, the height of the connecting portion 45 is higher than the height of the movable page body 41, and an outer edge 47 is formed at the position where the first shell 42 cooperates with the connecting portion 45. When the movable page 4 is installed, the side of the movable glass door 1 is abutted against the connecting portion 45, and cooperates with the outer edge 47 to form a limit for the movable glass door 1.

[0031] The first positioning groove 43 includes a first positioning groove body 431 for installing the positioning lock cover 611 and a second positioning groove body 432 arranged inwardly and extending inwardly in the first positioning groove body 431 for installing the positioning block 612; wherein, the positioning lock cover 611 is fixed in the first positioning groove body 431 by a bolt assembly, and by limiting the structure of the first positioning groove 43, the positioning lock cover 611 cooperates with the first positioning groove body 431 to limit the positioning block 612 in the second positioning groove body 432, so that the positioning block 612 has an axial movable gap in the second positioning groove body 432 and an adjustment gap is reserved around it to compensate for the manufacturing deviation, and the position can be moved according to assembly needs; specifically, the installation method of the positioning part on the fixed page 5 and the installation method of the positioning part on the movable page 4 will not be further described here.

[0032] The positioning block 612 is T-shaped and includes a supporting section 6121 supported in the second positioning slot 432 and an inserting section 6122 arranged on the supporting section 6121 and embeddable on the positioning lock cover 611, wherein the positioning lock cover 611 is provided with an inserting hole 6111 for the inserting section 6122 to be embedded.

[0033] The texture structure 613 is composed of a plurality of concentric annular bosses. The arrangement of the texture structure 613 greatly increases the frictional resistance between the positioning lock cover 611 and the positioning block 612, thereby preventing the glass door from being misaligned with the hinge under load and achieving the effect of preventing sagging.

[0034] The locking member 62 includes a locking washer 621 provided on the contact surface between the movable leaf 4 and the movable glass door 1 or the contact surface between the fixed leaf 5 and the fixed glass door 2, a locking screw 622 provided in the mounting hole 8 and cooperating with the positioning block 612, an extrusion sleeve 625 provided in sequence on the outer periphery of the locking screw 622 and the inner locking sleeve 623 and the outer locking sleeve 624, and the extrusion sleeve 625 provided on the outer locking sleeve 624 and capable of extruding the locking washer 624, wherein the extrusion sleeve 625 is provided in a straight section and has a tapered hole 6251 formed therein for the outer locking sleeve 624 to be inserted; the lower end of the outer locking sleeve 624 A conical section 6241 is formed that can be embedded in the conical hole 6251, and an equal-diameter hole 6242 is formed in the conical section 6241 for the inner locking sleeve 623 to be embedded in. An equal-diameter section 6231 is formed at the lower end of the inner locking sleeve 623 that can be embedded in the equal-diameter hole 6242. Specifically, a locking screw hole 6123 that cooperates with the locking screw 622 is formed on the plug-in section 6122. By limiting the structure of the locking member 62, the traditional double-ring structure is replaced with a three-ring structure, so that the assembly method can not only continue to use the conical hole pattern but also eliminate the hole gap, thereby improving the anti-drooping ability from multiple angles.

[0035] The cooperation principle between the extrusion sleeve 625, the outer locking sleeve 624 and the inner locking sleeve 623 is as follows: under the limitation of the structure of each component, the cooperation part of the outer locking sleeve 624 and the inner locking sleeve 623 is a straight surface, the cooperation part of the outer locking sleeve 624 and the extrusion sleeve 625 is a conical surface, and the cooperation part of the extrusion sleeve 625 and the mounting hole 8 is a straight surface. During the locking process of the locking screw 622, the extrusion sleeve 625 expands outward under the joint action of the outer locking sleeve 624 and the inner locking sleeve 623, so that the cooperation between the outer periphery of the extrusion sleeve 625 and the mounting hole 8 is smooth. The closing gap gradually decreases. At the same time, because the locking washer 621, the positioning lock cover 611, and the positioning block 612 reserve space for the locking washer 621 to be squeezed and deformed at the intersection of the three, when the extrusion sleeve 625 expands to be close to the inner wall of the mounting hole 8, the screw 622 is continuously tightened, and the extrusion sleeve 625 presses the locking washer 621 to deform until the outer periphery of the outer locking sleeve 624 is close to the inner wall of the mounting hole 8, so that the gap between the contact surface of the outer locking sleeve 624 and the mounting hole 8 is eliminated, thereby achieving the purpose of preventing the hinge and the glass door from sagging due to load displacement.

[0036] The structure of the connecting member 7 is the same as that of the locking member 62, and its specific composition and working principle will not be further described here.

[0037] The present application defines the structure of the locking mechanism 6 and further defines the structure of the positioning member 61 and the locking member 62. Through the cooperation between the various components, the shower door can provide an assembly gap at the beginning of installation to compensate for various manufacturing and installation deviations, and these assembly gaps can be eliminated after the installation is completed. The anti-drooping ability of the countersunk hole solution is further enhanced, the deviation resistance is increased in the deviation trend that may cause sagging, the glass door is prevented from sagging, and the product stability is improved.

[0038] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of application of the present invention and the contents of the specification should still fall within the scope of the present invention.
