Description

Technical Field

[0001] The utility model belongs to the technical field of bathroom door accessories, and particularly relates to an anti-sagging hinge structure. Background Art

[0002] Bathroom doors include a variety of opening methods such as flat opening, sliding, and folding. Flat opening bathroom doors usually use hinges to rotate, and the bathroom door rotates around the hinge axis of the hinge to open and close.

[0003] The hinge is connected to the bathroom door, and the hinge is used to provide support for the connected bathroom door. However, in order to facilitate the installation of the bathroom door, a gap is formed between the bathroom door and the hinge. After the bathroom door is installed, the gravity of the bathroom door causes the upper gap between the bathroom door and the hinge to increase, which easily causes the bathroom door to sag and tilt, causing the bathroom door to deviate when it is turned and closed, and water splashes out from the gap caused by the deviation of the bathroom door. Utility Model Content

[0004] The utility model aims to provide an anti-droop hinge structure to solve the technical problem that the bathroom door is prone to droop after the existing hinge and the bathroom door are connected.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] The utility model discloses an anti-droop hinge structure, comprising a movable seat connected to a movable door, wherein the movable seat comprises:

[0007] A leaf sheet, wherein the leaf sheet is extended with a support column, wherein a screw hole is provided in the support column, and wherein the screw hole is equipped with a bolt;

[0008] A mounting member, wherein the mounting member is provided with a bushing, the bushing is sleeved on the support column and an expansion groove is formed between the two;

[0009] A gasket is provided with a boss extending therefrom, and the bolt passes through the boss and the bushing and is connected to the support column so that the boss is inserted into the expansion groove and expands the bushing.

[0010] The utility model has at least the following beneficial effects: the bushing of the mounting piece is sleeved on the supporting column, and the bolts are threadedly connected through the screw holes of the gasket and the leaf piece, so that the boss is inserted into the expansion groove formed by the bushing and the supporting column, and the bushing is enlarged, so that the bushing is interference-connected to the movable door, so that the movable seat can be firmly connected to the movable door, and a gap between the movable door and the movable seat is avoided, which causes the movable door to sag and tilt, thereby affecting the blocking effect of water splashes.

[0011] As a further improvement of the above technical solution, the boss is in a truncated cone shape, and the diameter of the outer peripheral surface of the boss gradually decreases toward the direction approaching the expansion groove.

[0012] Through the above arrangement, the diameter of the boss facing the expansion groove is small, which facilitates the boss to penetrate into the expansion groove. The diameter of the boss away from the expansion groove is large, so that the diameter of the outer peripheral surface of the boss penetrating the expansion groove is continuously increased, thereby expanding the bushing and achieving interference fit between the bushing and the movable door.

[0013] As a further improvement of the above technical solution, the anti-droop hinge structure also includes a fixed seat connected to the door frame or the fixed door, and the fixed seat and the movable seat are hinged.

[0014] Through the above arrangement, the movable seat is connected to the movable door, the fixed seat is connected to the door frame or the fixed door, and the movable seat and the fixed seat are hinged so that the movable door can rotate relative to the door frame or the fixed door to realize the rotation switch of the movable door.

[0015] As a further improvement of the above technical solution, the fixed seat and the movable seat are both provided with a pin shaft hole, the pin shaft hole is arranged obliquely, and a hinge shaft is passed through the pin shaft hole so that the movable seat is inclined and upward relative to the fixed seat.

[0016] Through the above arrangement, the hinge shaft is passed through the pin shaft holes of the movable seat and the fixed seat so that the movable seat is tilted and upward relative to the fixed seat. When the movable seat is connected to the movable door, the movable seat can be pressed down by the gravity of the movable door to pre-deform the hinge shaft, so that the hinge shaft is firmly connected to the movable seat and the fixed seat. By deforming the hinge shaft in advance, the subsequent anti-droop hinge structure can be prevented from being deformed by the gravity of the movable door for a long time after installation, causing the hinge shaft to tilt and droop.

[0017] As a further improvement of the above technical solution, the anti-sagging hinge structure is configured so that when the movable door and the movable seat are connected, the movable seat is pressed down by the gravity of the movable door and corresponds horizontally to the fixed seat.

[0018] Through the above arrangement, when the movable door and the movable seat are connected, the movable seat, which is tilted and upward relative to the fixed seat, is pressed down by the gravity of the movable door, causing the hinge axis to deform, so that the movable seat and the fixed seat correspond horizontally, and the movable door can rotate horizontally relative to the door frame or the fixed door, so that the movable door can be opened and closed smoothly.

[0019] As a further improvement of the above technical solution, the fixing seat includes the leaf piece, the gasket and the mounting member for connecting and fixing the door.

[0020] Through the above arrangement, when the fixed seat is used to connect the fixed door, the fixed seat includes a leaf, a gasket and a mounting part having the same structure as the movable seat, and the bushing is enlarged by the same boss to make the fixed seat firmly connected to the fixed door, thereby avoiding a gap between the fixed door and the fixed seat, which would cause the fixed door to sag.

[0021] As a further improvement of the above technical solution, the gasket is provided with an embedding hole corresponding to the screw hole, and the bolt includes a screw head part and a screw tail part, and the screw tail part is connected to the screw hole after passing through the embedding hole, and the screw head part is embedded in and abuts against the embedding hole.

[0022] Through the above arrangement, the bolt screwed into the screw hole drives the boss to move toward the expansion groove by abutting the embedding hole through the screw head portion, and the screw head portion of the bolt can be hidden in the embedding hole of the gasket, reducing the length of the anti-sagging hinge structure so that the anti-sagging hinge structure can be made narrower.

[0023] As a further improvement of the above technical solution, a connecting hole communicating with the embedding hole is formed in the hollow of the boss, and the hole diameter of the connecting hole matches the diameter of the outer circumference of the support column.

[0024] Through the above arrangement, the bolt can pass through the embedding hole and the connecting hole in sequence and then be connected to the screw hole. When the boss is inserted into the expansion groove, the support column can be inserted into the connecting hole of the boss. The outer peripheral surface of the support column and the aperture of the connecting hole match, so that the boss can provide support for the support column, and the gasket and the leaf can be more stable.

[0025] As a further improvement of the above technical solution, the bushing is provided with a notch, and the notch divides the bushing into a first bushing and a second bushing along its extending direction.

[0026] Through the above arrangement, the notch divides the bushing into a first bushing and a second bushing. When the bushing is expanded by the boss, the bushing divided into two has a better deformation space and is easier to be expanded by the boss. The boss can also prevent the bushing from being expanded and causing the bushing to be torn, thereby extending the service life of the bushing.

[0027] As a further improvement of the above technical solution, both the first bushing and the second bushing are connected with reinforcing ribs, and the two reinforcing ribs are symmetrical about the notch.

[0028] Through the above arrangement, the diameters of the first bushing and the second bushing are further increased to ensure interference connection between the bushing and the movable door, and the reinforcing ribs can also enhance the strength and rigidity of the first bushing and the second bushing, thereby improving the stability of the connection between the bushing and the movable door.

[0049] Reference Figures 1 to 5 , several embodiments of the anti-sagging hinge structure of the utility model are given below.

[0050] like Figures 1 to 5 As shown, the anti-droop hinge structure 100 of the embodiment of the utility model includes a movable seat 110, and the movable seat 110 is used to connect with the movable door to stably support the movable door to prevent the movable door from sagging.

[0051] In this embodiment, the movable seat 110 includes a leaf 200, a mounting member 300 and a gasket 500. Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.

[0052] It is understandable that the leaf 200 extends with a support column 210 for supporting the movable door, and a screw hole 211 is provided in the support column 210, and a bolt 220 is provided in the screw hole 211. Figure 4 and Figure 5 As shown, the bolt 220 can penetrate into the screw hole 211 and be threadedly connected with the support column 210 .

[0053] It is understandable that the mounting member 300 is connected to the leaf 200. Specifically, a bushing 310 is provided on the mounting member 300, and the bushing 310 is sleeved on the support column 210. Figure 4 and Figure 5 As shown, the bushing 310 is used to protect the support column 210, so as to prevent the support column 210 from rubbing against the movable door when supporting the movable door, thereby causing wear of the support column 210 in the long run. An expansion groove 400 is formed between the bushing 310 and the support column 210, such as Figure 5 shown.

[0054] It is understood that the gasket 500 is extended with a boss 510, such as Figure 2 As shown, the bolt 220 passes through the boss 510 and the bushing 310 and is connected to the support column 210, so that the boss 510 is close to and penetrates the expansion groove 400, and the boss 510 is continuously squeezed from the inside to the outside by tightening the threads of the bolt 220 and the screw hole 211, and the bushing 310 is expanded, as shown in FIG. Figure 5 shown.

[0055] It can be understood that the movable door is provided with a through hole. When the movable door is installed, the support column 210 with the bushing 310 is inserted into the through hole. When the bolt 220 passes through the boss 510 and the screw hole 211 to connect, the movable door is sandwiched between the gasket 500 and the leaf 200. Figure 5 shown.

[0056] With such arrangement, the bushing 310 enlarged by the boss 510 fills the gap between the movable door and the bushing 310, so that the movable door and the movable seat 110 are interference fitted, and the movable seat 110 can be firmly connected to the movable door, avoiding the situation where there is a gap between the movable door and the movable seat 110, which makes it easy for the bathroom door 800 to sag and tilt, and cannot completely block the splashing water.

[0057] In this embodiment, the sheet 200, the mounting member 300 and the gasket 500 are laid in sequence from front to back. Figure 1 , Figure 2 , Figure 4 and Figure 5 shown.

[0058] It can be understood that the support column 210 extends backward from the rear end surface of the leaf piece 200, the screw hole 211 extends forward and backward and is coaxially arranged with the support column 210, and the screw hole 211 is a blind hole and is connected to the rear end surface of the support column 210. Figure 5 As shown, the front end surface of the leaf piece 200 is smooth and flat to prevent splashing water from penetrating into the anti-sagging hinge structure 100.

[0059] It can be understood that the bushing 310 is disposed on the rear end surface of the mounting member 300. Figure 4As shown, when the bushing 310 is sleeved on the support column 210 from back to front, the front end surface of the mounting member 300 and the rear end surface of the leaf 200 are in contact. The inner circumference of the bushing 310 is in a stepped shape with a diameter decreasing from back to front, so that the inner circumference with a larger diameter at the rear end of the bushing 310 and the outer circumference of the support column 210 surround and form an annular expansion groove 400 with an opening facing backward, so that the inner circumference with a smaller diameter at the front end of the bushing 310 and the outer circumference of the support column 210 are connected, so that when the support column 210 with the bushing 310 is inserted into the through hole of the movable door, the bushing 310 is firmly mounted in the through hole through the connected support column 210, and the bushing 310 is not easily deformed. Figure 5 shown.

[0060] It can be understood that the boss 510 extends forward from the front end surface of the gasket 500, the boss 510 and the expansion groove 400 are opposite to each other front to back, and the bolt 220 passes through the boss 510 from back to front and is connected to the screw hole 211, so that the boss 510 penetrates into the expansion groove 400 from back to front and expands the bushing 310 from back to front.

[0061] It can be understood that the boss 510 is in the shape of a truncated cone, and the front end of the boss 510 can penetrate into the expansion groove 400. The diameter of the outer circumference of the boss 510 gradually decreases toward the expansion groove 400, that is, the diameter of the outer circumference of the boss 510 near the expansion groove 400 is small, which facilitates the boss 510 to penetrate into the expansion groove 400; the diameter of the outer circumference of the boss 510 away from the expansion groove 400 is large, and as the distance of the boss 510 penetrating into the expansion groove 400 increases, the outer circumference of the boss 510 gradually contacts and squeezes the bushing 310 from the inside to the outside, so that the bushing 310 expands the hole wall of the interference connection through hole.

[0062] It is understandable that the anti-droop hinge structure 100 further includes a fixed seat 120, the fixed seat 120 is connected to the door frame or the fixed door, and the fixed seat 120 and the movable seat 110 are hinged, such as Figure 1 and Figure 3 As shown, the movable door can rotate relative to the door frame or the fixed door around the hinge axis to achieve the rotation opening and closing of the movable door.

[0063] It is understandable that the hinge structure between the fixed seat 120 and the movable seat 110 includes a pin hole 600 and a hinge axis. Specifically, the movable seat 110 is provided with a pin hole 600, and the fixed seat 120 is provided with a pin hole 600. Figure 1 , Figure 3 and Figure 4 As shown, the hinge shaft is penetrated through the pin shaft hole 600 of the movable seat 110 and the pin shaft hole 600 of the fixed seat 120, so that the movable seat 110 and the fixed seat 120 can rotate relative to each other about the axis of the hinge shaft.

[0064] It is understandable that, since the movable seat 110 is connected to the movable door, the movable seat 110 needs to bear the gravity of the movable door. Since the movable seat 110 and the fixed seat 120 are hinged, the hinge structure between the movable seat 110 and the fixed seat 120 needs to bear the gravity of the movable door, and the hinge structure between the movable seat 110 and the fixed seat 120 is easy to deform, causing the movable door to tilt and sag easily.

[0065] In this embodiment, the pin hole 600 is arranged tilted, that is, the hinge shaft passing through the pin hole 600 is in a tilted state, so that the movable seat 110 tilts upward relative to the fixed seat 120 .

[0066] With such arrangement, when the movable door and the movable seat 110 are connected, the hinge shaft passing through the pin shaft hole 600 of the movable seat 110 is deformed and pressed down by the gravity of the movable door, so that the tilted and upward movable seat 110 is pressed down relative to the fixed seat 120. By pre-deforming the hinge structure between the movable seat 110 and the fixed seat 120 in advance, the hinge shaft is firmly connected to the movable seat 110 and the fixed seat 120, thereby avoiding the situation in which the hinge shaft of the anti-droop hinge structure 100 undergoes structural deformation due to the gravity of the movable door during long-term use, causing the movable door to tilt and droop.

[0067] It can be understood that during the connection process between the movable door and the movable seat 110, the movable seat 110 is pressed down by the gravity of the movable door and corresponds horizontally to the fixed seat 120, so that the deformed hinge axis extends up and down, and the movable seat 110 and the fixed seat 120 can rotate relative to each other around the hinge axis extending up and down, so that the movable door can be turned and opened horizontally and stably.

[0068] In this embodiment, the pin hole 600 is tilted relative to the upper and lower axes in a direction away from the movable door rotation switch, so that when the movable door and the movable seat 110 are connected, the movable door drives the hinge shaft in the pin hole 600 to be pressed down and deformed in a direction close to the movable door rotation switch, thereby pressing the tilted and upward movable seat 110 down to be horizontally aligned with the fixed seat 120.

[0069] In this embodiment, the bathroom door 800 includes a movable door and a fixed door, and the fixing seat 120 is connected to the fixed door.

[0070] It can be understood that when the fixed seat 120 is used to connect the fixed door, the structure of the fixed seat 120 is basically the same as the structure of the movable seat 110, that is, the fixed seat 120 includes a leaf 200, a gasket 500 and a mounting member 300. Correspondingly, the fixed door is provided with a through hole, and the boss 510 is connected to the screw hole 211 through the bolt 220 to squeeze and expand the bushing 310, so that the bushing 310 is interference-connected with the through hole of the fixed door, so that the fixed seat 120 and the fixed door are firmly connected to avoid the fixed door from sagging and tilting, resulting in a gap between the fixed door and the movable door that is rotated and closed.

[0071] It is understandable that the gasket 500 is provided with an embedding hole 520 corresponding to the screw hole 211. Figure 4 As shown, it is convenient for the bolt 220 to lock the washer 500 and the leaf 200. Specifically, the bolt 220 includes a screw head portion 221 and a screw tail portion 222. Figure 2 As shown, the screw tail portion 222 penetrates into the embedding hole 520 and the boss 510 and is threadedly connected with the screw hole 211 , and the screw head portion 221 is embedded in and abuts against the embedding hole 520 .

[0072] In this configuration, as the screw tail portion 222 is continuously threadedly connected to the screw hole 211, the screw head portion 221 drives the gasket 500 to move toward the direction close to the support column 210, so that the boss 510 continuously extends into the expansion groove 400 and expands the bushing 310. Since the screw head portion 221 abuts against the embedding hole 520, the gasket 500 and the leaf 200 are tightly connected through the bolt 220 and the screw hole 211, and the movable door or fixed door is firmly clamped between the gasket 500 and the leaf 200. Since the screw head portion 221 is embedded in the embedding hole 520, the screw head portion 221 can be hidden in the gasket 500, reducing the front and rear length of the gasket 500, and realizing the extremely narrow design of the anti-droop hinge structure 100.

[0073] It can be understood that the boss 510 is hollow and has a connecting hole 511 formed therein. Figure 2 As shown. The connection hole 511 and the embedding hole 520 are connected front to back, so that the bolt 220 can pass through the embedding hole 520 and the connection hole 511 from back to front in sequence, and the screw head part 221 of the bolt 220 is embedded in the embedding hole 520 and cannot penetrate the connection hole 511. The hole diameter of the connection hole 511 matches the outer peripheral surface diameter of the support column 210. When the front end of the boss 510 is inserted into the expansion groove 400, the rear end of the support column 210 is inserted into the connection hole 511, so that the gasket 500 and the leaf 200 are relatively fixed, making the anti-droop hinge structure 100 more stable.

[0074] It can be understood that the bushing 310 is provided with a notch 320, and the notch 320 divides the bushing 310 into a first bushing 331 and a second bushing 332 along its extending direction. Figure 4 shown.

[0075] With such arrangement, when the bushing 310 is squeezed and stretched open by the boss 510 , the bushing 310 can be expanded and deformed along the notch 320 . The notch 320 provides the bushing 310 with a good deformation space, making it easier to stretch open and less likely to be damaged by the boss 510 , thereby extending the service life of the bushing 310 .

[0076] It can be understood that the extending direction of the notch 320 is perpendicular to the sleeve direction of the bushing 310. For example, the notch 320 can extend up and down so that the first bushing 331 and the second bushing 332 are symmetrically distributed left and right. In this embodiment, the notch 320 extends left and right so that the first bushing 331 and the second bushing 332 are symmetrically distributed up and down, so that the expanded bushing 310 can better support the movable door and the fixed door from the top and bottom directions.

[0077] It is understandable that the bushing 310 is made of a material with good toughness and rigidity such as nylon, silicone or rubber, which is not specifically limited here, so that the bushing 310 has good deformation ability and wear resistance.

[0078] Furthermore, the first bushing 331 and the second bushing 332 are both connected with reinforcing ribs 340, such as Figure 4 As shown, the two reinforcing ribs 340 are symmetrically distributed about the notch 320. Specifically, the two reinforcing ribs 340 are respectively arranged on the outer arc surface of the first bushing 331 and the outer arc surface of the second bushing 332 to enhance the strength and rigidity of the first bushing 331 and the second bushing 332, and improve the stability of the connection structure between the bushing 310 and the movable door and the fixed door. Since the notch 320 extends in the left-right direction, the two reinforcing ribs 340 symmetrical in the upper and lower directions are convenient for increasing the diameter of the bushing 310 in the upper and lower directions when the bushing 310 is expanded and deformed, so as to ensure that the movable door and the fixed door are firmly supported in the upper and lower directions.

[0079] It can be understood that the diameter of the bushing 310 is smaller than the aperture of the through hole, which facilitates the bushing 310 and the support column 210 to be inserted into the through hole; the diameter formed by the two reinforcing ribs 340 is the aperture of the through hole, and the edge of the reinforcing rib 340 extends obliquely toward the direction close to the bushing 310 to guide the bushing 310 connected with the reinforcing rib 340 to penetrate into the through hole.

[0080] In this embodiment, the two reinforcing ribs 340 are integrally formed with the first bushing 331 and the second bushing 332 respectively, and the first bushing 331 and the second bushing 332 are integrally formed and connected.

[0081] It is understandable that the bushing 310 can be connected to the mounting member 300 by means of embedding, sleeve connection, etc. In this embodiment, the bushing 310 can be fixedly connected to the mounting member 300 by means of integral molding.

[0082] It is understandable that when the movable seat 110 is connected to the movable door and the fixed seat 120 is connected to the fixed door, at this time, the rear end face of the gasket 500 reveals the bolts 220 and the embedding holes 520, and water vapor, dust and other debris can easily float and penetrate into the gasket 500 and the gasket 500 structure.

[0083] In this embodiment, the gasket 500 is clamped with the decorative cover plate 700. Figures 1 to 5Specifically, after the bolt 220 is connected to the screw hole 211, the decorative cover plate 700 can be clamped on the gasket 500 from the back to the front, covering and hiding the structure of the gasket 500, preventing dust, water vapor, etc. from corroding the internal bolt 220 and other structures, and making the anti-droop hinge structure 100 more beautiful.

[0084] It is understandable that the leaf 200 is hollow and has a mounting slot 230 with an opening facing backwards. Figure 4 As shown, the support column 210 extends backward from the inner wall of the mounting groove 230 to make the leaf 200 lightweight, reduce the weight of the leaf 200, reduce material costs, and reduce the front-to-back length of the leaf 200, facilitating the extremely narrow setting of the anti-droop hinge structure 100.

[0085] In this embodiment, a plurality of reinforcing blocks 240 are disposed in the mounting groove 230, and the reinforcing blocks 240 are connected to the support column 210 and the inner wall of the mounting groove 230. Figure 4 As shown, the support column 210 is provided with stable support, so that the anti-sagging hinge structure 100 is firmly connected with the movable door and the fixed door.

[0086] It is understandable that each support column 210 may be connected to one, two, three or four reinforcement blocks 240, which is not specifically limited herein.

[0087] It is understandable that the mounting member 300 of the fixing seat 120 is extended with an anti-pinch member 350, such as Figure 2 When the bushing 310 on the mounting member 300 is sleeved on the support column 210, the anti-clamping member 350 is inserted into the leaf 200 of the fixed seat 120 and is located beside the hinge structure of the movable seat 110 and the fixed seat 120. The anti-clamping member 350 reduces the relative rotation gap between the movable seat 110 and the fixed seat 120 to prevent fingers and other parts from being pinched by the relatively rotating movable seat 110 and the fixed seat 120.

[0088] Installation principle: Assemble the anti-sagging hinge structure 100 in advance to make the movable seat 110 and the fixed seat 120 hingedly connected.
