Description

Technical Field

[0001] This utility model relates to the field of shower room technology, specifically to a hinge and a shower room. Background Technology

[0002] Shower enclosures are a common feature in modern bathrooms, and the smooth operation and long-term stability of their sliding doors directly impact the user experience and product lifespan. In practical applications, due to the significant weight of shower enclosure doors (usually made of tempered glass) and the unavoidable manufacturing tolerances and installation errors in the hinge system, there are inherent assembly gaps in the sliding doors from the outset. While these gaps provide necessary tolerance for installation adjustments, they also create a potential for sagging over time. As time passes, under the weight of the door and the repetitive loads of daily opening and closing, the sliding door will gradually shift downwards and tilt outwards, leading to problems such as seal failure, difficulty closing, and even friction between the bottom of the door and the floor. Current industry solutions commonly involve adjusting the door position by adding countersunk holes at the mounting holes or using set screws for post-installation adjustments. However, these methods often only compensate in one direction and cannot simultaneously address the dual problems of door sagging and outward shifting, let alone achieve multi-directional gap control and long-term stability during the initial installation phase. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a hinge and a shower enclosure. This hinge uses an adjustable gap to compensate for manufacturing and installation deviations and increases resistance to sagging by adjusting the offset that may cause the door to sag.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a hinge suitable for rotating a movable door relative to a fixed door. The hinge has locking positions between the hinge and the two door bodies, including: a fixed hinge, fixedly connected to the fixed door body, extending horizontally, and having a first locking position and a second locking position spaced horizontally; a movable hinge, fixedly connected to the movable door body, rotatably connected to the fixed hinge about a vertical axis, and having a third locking position and a fourth locking position, wherein only one is a direct locking position; and a first adjusting mechanism, including a first adjusting sleeve and a first adjusting member, the first adjusting sleeve being vertically inserted through the first locking position and either the third or fourth locking position to form a first adjustable gap; the first adjusting... The hinge component is threadedly engaged with the fixed or movable hinge, and applies a vertical force to the target locking position through vertical adjustment; the second adjustment mechanism includes a second adjustment sleeve and a second adjustment member, the second adjustment sleeve is inserted into the second locking position along a third direction at an angle to the horizontal direction to form a second adjustable gap; the second adjustment member is threadedly engaged with the fixed hinge, and applies a horizontal rightward component force and a vertical downward component force through third-direction adjustment; after the first and second adjustment members are locked, the first and second adjustable gaps are reduced or eliminated, and a rigid connection is formed between the hinge and the fixed and movable door bodies to suppress door sagging and lateral displacement.

[0006] The second technical solution is based on the first technical solution, wherein the first adjustment mechanism acts on the first locking position, the first adjustment member is threadedly engaged with the fixed hinge, and a first vertically upward support force is applied to the first locking position by adjusting vertically upward.

[0007] The third technical solution is based on the first technical solution, wherein the third locking position is a direct locking position, the first adjusting mechanism acts on the fourth locking position; the first adjusting member is threadedly engaged with the movable hinge, and applies a vertically upward second supporting force to the fourth locking position through vertical upward adjustment.

[0008] The fourth technical solution is based on the first technical solution, wherein the fourth locking position is a direct locking position, the first adjusting mechanism acts on the third locking position; the first adjusting member is threadedly engaged with the movable hinge, and applies a vertically downward third clamping force to the third locking position by adjusting vertically downward.

[0009] The fifth technical solution is based on any one of the first to fourth technical solutions, wherein the locking position is a stepped hole, and the first adjusting sleeve and the second adjusting sleeve are both T-shaped sleeves, including: a flange cover covering the end face of the stepped hole; a gap sleeve forming an adjustable gap with the wall of the stepped hole; and an axial threaded hole penetrating the flange cover and the gap sleeve for countersunk installation of the locking screw.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the first adjusting component includes: a vertical set screw, which engages with the hinge thread in the vertical direction; and a wedge-shaped force transmission block, located between the vertical set screw and the first adjusting sleeve, the curved surface of which abuts against the first adjusting sleeve to convert the axial force of the set screw into a vertical force.

[0011] The seventh technical solution is based on the fifth technical solution, wherein the second adjusting component includes: an oblique set screw, which is threadedly engaged with the fixed hinge in a third direction; and an L-shaped force transmission block, located between the oblique set screw and the second adjusting sleeve, whose two arms transmit the horizontal rightward component force and the vertical downward component force.

[0012] The eighth technical solution is based on the seventh technical solution, wherein the angle between the third direction and the horizontal direction is 45°±5°.

[0013] The ninth technical solution is based on any one of the first to eighth technical solutions, a shower room, including a fixed door body, a movable door body and the aforementioned hinge, wherein there are two hinges, which are respectively installed at the upper and lower ends of the door body along the vertical direction.

[0014] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0015] In the first technical solution and related embodiments, through the synergistic action of the first and second adjustment mechanisms, the hinge can eliminate the adjustable gap between itself and the fixed and movable door bodies, forming multi-directional resistance. This effectively resists the hinge from sagging and shifting outward relative to the fixed door body, as well as the movable door body from sagging and detaching relative to the hinge, ensuring the stability and durability of the door body. Specifically, the fixed and movable hinges are provided with multiple locking positions. The first adjustment sleeve is vertically inserted to form the first adjustable gap, and the second adjustment sleeve is obliquely inserted to form the second adjustable gap. The adjusting member generates multi-directional force through threaded advancement. After locking, the gap is eliminated, forming a rigid connection. This adjustable gap is compatible with initial assembly errors, compensates for manufacturing and installation deviations, and can eliminate assembly gaps that could cause the door body to sag after installation. It also adds adjustment function to increase offset resistance in cases where there is a tendency for the door body to sag, hindering sagging and improving product stability.

[0016] In the second technical solution and related embodiments, when the first adjustment mechanism acts on the first locking position, the first adjustment member is adjusted vertically upward to apply a vertically upward first support force to the first locking position. According to the principle of mutual force, the fixed door body generates a vertically downward reaction force on the hinge at the first locking position, which suppresses the tendency of the hinge to rotate clockwise around the second locking position and the sagging of the fixed door body.

[0017] In the third technical solution and related embodiments, when the third locking position is the direct locking position, the first adjusting mechanism acts on the fourth locking position, and applies a second supporting force vertically upward to the fourth locking position by adjusting the first adjusting member vertically upward, thereby preventing the movable door body from flipping and sagging around the direct locking position.

[0018] In the fourth technical solution and related embodiments, when the fourth locking position is the direct locking position, the first adjusting mechanism acts on the third locking position, and applies a vertically downward third pressing force to the third locking position by adjusting the first adjusting member vertically downward, thereby enhancing the ability of the movable door body and the hinge to resist lateral separation.

[0019] In the fifth technical solution and related embodiments, the locking position is a stepped hole, and the flange cover of the T-sleeve covers the end face of the stepped hole. The end face is pressed together to form a stable support and limiting function. The adjustable gap formed between the clearance sleeve and the wall of the stepped hole allows for fine-tuning during assembly, ensuring the fit between the hinge and the door body and enhancing the hinge's anti-sagging and anti-detachment capabilities.

[0020] In the sixth technical solution and related embodiments, the vertical set screw engages with the door body thread to provide axial force. The curved surface of the wedge-shaped force transmission block abuts against the first adjusting sleeve, converting the axial force of the set screw into a vertical support force, providing additional support for the hinge in the vertical direction, and resisting the sagging and offset of the door body.

[0021] In the seventh technical solution and related embodiments, the oblique set screw engages with the door body thread to provide axial force. The L-shaped force transmission block decomposes the axial force of the oblique set screw into a horizontal rightward component and a vertical downward component, which are transmitted to the second adjusting sleeve respectively, forming multi-directional resistance to resist the sag and outward movement of the hinge.

[0022] In the eighth technical solution and related embodiments, the angle between the third direction and the horizontal direction is 45°±5°. This design enables the second adjusting member to generate horizontal rightward and vertical downward components simultaneously when force is applied, achieving a balanced distribution of horizontal and vertical components.

[0023] In the ninth technical solution and related embodiments, the shower enclosure uses two hinges installed at the top and bottom of the door in the vertical direction to ensure the stability and balance of the movable door during rotation. The anti-sagging adjustment function of the hinges eliminates the torsional stress of the door. Attached Figure Description

[0043] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0044] In this embodiment, for the sake of referring to the accompanying drawings and for ease of explanation, the horizontal direction X is defined as the left-right direction, the vertical direction Y as the up-down direction, and the third direction Z as the direction that forms an angle with the horizontal direction. However, this does not mean that the directional limitation of this patent is imposed.

[0045] See Figures 1 to 12 ,like Figure 1As shown, a hinge 100 is adapted to enable a movable door 120 to rotate relative to a fixed door 110. A locking position is provided between the hinge 100 and the fixed door 110 and the movable door 120. The hinge 100 includes a fixed hinge 1, a movable hinge 2, a first adjustment mechanism, and a second adjustment mechanism.

[0046] Fixed hinge 1, such as Figures 1 to 3 ,as well as Figure 5 As shown, it is fixed to the fixed door body 110, made of high-strength aluminum alloy, extends along the horizontal direction X, and has a first locking position A and a second locking position B distributed at intervals along the horizontal direction X.

[0047] Specifically, the main frame of the fixed hinge 1 has two stepped mounting holes 19, serving as the first locking position A and the second locking position B, for fixed connection with the fixed door body 110. The stepped hole structure of the locking positions is suitable for installing adjustment mechanisms. Figure 1 As shown, the fixed hinge 1 has a U-shaped recess 11 at one end facing the movable hinge 2 to accommodate the connecting part 21 of the movable hinge 2. The upper and lower ends of the recess 11 are provided with mounting seats 12 protruding in the horizontal direction X. The mounting seats 12 have mounting grooves 13 extending in the parallel horizontal direction X for mounting U-shaped soft rubber pads 14, providing cushioning and noise reduction functions. The bottom of both the upper and lower mounting grooves 13 has a first shaft hole 15 in the vertical direction Y for mounting the shaft 23. A first gasket 16 is provided between the fixed hinge 1 and the fixed door body 110 to prevent hard contact between the metal and the glass.

[0048] The fixed hinge 1 is provided with a first decorative cover 17, which is used to cover the mounting hole 19 after installation. The first decorative cover 17 has side plates at both ends along the vertical direction Y, so as to cover the fixed hinge 1. The first decorative cover 17 is fixed by two first elastic pins 18. The two first elastic pins 18 are inserted upward from the bottom of the fixed hinge 1 (the lower end of the vertical direction Y) into the pin holes of the fixed hinge 1 and the decorative cover, so as to fix the first decorative cover 17 to the fixed hinge 1.

[0049] Activity hinge 2, such as Figures 1 to 3 ,as well as Figure 5 As shown, it is fixed to the movable door body 120 and rotatably connected to the fixed hinge 1 around the vertical axis. It has a third locking position C and a fourth locking position D, of which only one is a direct locking position.

[0050] Specifically, the movable hinge 2 is made of high-strength cast aluminum alloy and has two mounting holes 19, which are the third locking position C and the fourth locking position D, for fixing to the movable door body 120. One locking position is a screw mounting hole 19, and the other locking position is a stepped hole mounting hole 19. Figure 1As shown, the movable hinge 2 has a connecting portion 21 protruding horizontally in the X direction at one end facing the fixed hinge 1, which fits into the clearance groove 11 of the fixed hinge 1. The connecting portion 21 has a second shaft hole 22 penetrating vertically in the Y direction. The second shaft hole 22 mates with the first shaft hole 15, which is suitable for installing the shaft 23 so that the movable hinge 2 and the fixed hinge 1 are rotatably connected. A bushing 24 is fitted over the shaft 23. The bushing 24 is a hollow copper alloy sleeve, which is suitable for fitting the shaft 23 and installing it in the second shaft hole 22 for guidance and friction reduction. Similarly, a second gasket 25 is provided between the movable hinge 2 and the movable door body 120 to prevent hard contact between metal and glass. A third gasket 26 is provided between the upper surface of the connecting portion 21 and the fixed seat 12 for adjusting the rotation clearance. A fourth gasket 27 is provided between the lower surface of the connecting portion 21 and the fixed seat 12 to resist wear. A fifth gasket 28 is provided on the contact surface between the connecting portion 21 and the bottom of the clearance groove 11 to provide a shock absorption effect.

[0051] The movable hinge 2 is provided with a second decorative cover 29, which is used to cover the mounting hole 19 after installation. The second decorative cover 29 has side plates at both ends along the vertical direction Y to cover the fixed hinge 1. It is fixed by two second elastic pins 34. The second elastic pins 34 are located above and below the connecting part 21 along the horizontal direction X of the movable hinge 2. They are inserted into the pin holes of the movable hinge 2 and the second decorative cover 29 to fix the second decorative cover 29 to the movable hinge 2.

[0052] In the installation direction of each locking position, a conical sleeve 30, a plastic sleeve 31, a metal sleeve 32, and a screw decorative cover 33 are sequentially fitted from the inside out. The outer conical surface of the conical sleeve 30 mates with the inner conical surface of the stepped hole in the locking position for initial positioning. The plastic sleeve 31 is fitted over the conical sleeve 30, with its inner conical surface fitting against the outer conical surface of the sleeve. The metal sleeve 32 covers the outer side of the plastic sleeve 31. The screw decorative cover 33 has a mounting screw hole for fixing to the locking screw. When the first adjusting member 5 and the second adjusting member 7 are locked, the conical surface of the conical sleeve 30 expands, pushing the plastic sleeve 31 and the metal sleeve 32 to expand radially, ultimately completely filling the adjustable gap between the locking position and the door mounting hole 19. The screw decorative cover 33 then completely covers the head of the locking screw, achieving a decorative effect. This multi-layer sleeve structure, through the progressive expansion of the conical surface fit, ensures the uniformity and reliability of gap elimination. The locking screw of the direct locking position also adopts the same structure and principle.

[0053] The first regulating mechanism, such as Figure 3 and Figure 5 As shown, it includes a first adjusting sleeve 4 and a first adjusting member 5. The first adjusting sleeve 4 passes through the first locking position A and the third locking position C or the fourth locking position D along the vertical direction Y, and forms a first adjustable gap 10 between it and the two positions;

[0054] Specifically, such as Figure 7As shown, the first adjusting sleeve 4 includes a flange cover 41 and a clearance sleeve 42. The flange cover 41 covers the end face of the stepped hole, and the clearance sleeve 42 forms an adjustable gap with the wall of the stepped hole. The first adjusting sleeve 4 is provided with an axial screw hole 43, which penetrates the flange cover 41 and the clearance sleeve 42 for countersunk installation of locking screws.

[0055] The first adjusting member 5 is threadedly engaged with the fixed hinge 1 or the movable hinge 2, and applies a vertical force in the Y direction to the target locking position through vertical Y adjustment.

[0056] Specifically, such as Figure 3 and Figure 5 As shown, the first adjusting member 5 includes a vertical set screw 51 and a wedge-shaped force transmission block 52. The vertical set screw 51 engages with the hinge thread along the vertical direction Y. The direction in which the vertical set screw 51 enters the hinge can be adjusted downwards along the vertical direction Y, or upwards along the vertical direction Y.

[0057] Wedge-shaped force transmission block 52, such as Figure 8 As shown, located between the vertical set screw 51 and the first adjusting sleeve 4, its curved surface 53 abuts against the first adjusting sleeve 4, converting the axial force of the set screw into a vertical Y-force.

[0058] In this embodiment, the locking position is a stepped hole. The flange cover 41 of the T-shaped sleeve covers the end face of the stepped hole, and the end face is pressed together to form a stable support and limiting function. The adjustable gap formed between the gap sleeve 42 and the wall of the stepped hole allows for fine adjustment during assembly, ensuring the fit between the hinge 100 and the door body, and enhancing the anti-sagging and anti-detachment capabilities of the hinge 100.

[0059] In this embodiment, the vertical set screw 51 engages with the hinge thread to provide axial force. The curved surface 53 of the wedge-shaped force transmission block 52 abuts against the first adjusting sleeve 4, converting the axial force of the set screw into a vertical support force, providing additional vertical support for the hinge 100 and resisting the sagging and offset of the door.

[0060] Second regulatory mechanism, such as Figure 3 and Figure 5 As shown, it is provided with a second adjusting sleeve 6 and a second adjusting member 7. The second adjusting sleeve 6 is inserted into the second locking position B along a third direction Z at an angle to the horizontal direction X, and forms a second adjustable gap 20 with the fixed hinge 1.

[0061] Specifically, such as Figure 7As shown, the second adjusting sleeve 6, like the first adjusting sleeve 4, includes a flange cover 41 and a clearance sleeve 42. The flange cover 41 covers the end face of the stepped hole, and the clearance sleeve 42 forms an adjustable clearance with the wall of the stepped hole. The second adjusting sleeve 6 is provided with an axial screw hole 43, which penetrates the flange cover 41 and the clearance sleeve 42 for countersunk installation of locking screws. The angle between the third direction Z and the horizontal direction X is 45°±5°.

[0062] like Figures 3 to 6 As shown, the second adjusting member 7 is threadedly engaged with the fixed hinge 1, and applies a horizontal rightward component force F3 and a vertical downward component force F2 to the second adjusting sleeve 6 through a third-direction Z adjustment.

[0063] Specifically, the second adjusting component 7 includes an angled set screw 71 and an L-shaped force transmission block 72. The angled set screw 71 is threaded into the fixed hinge 1 along the third direction Z. The L-shaped force transmission block 72 is located between the angled set screw 71 and the second adjusting sleeve 6, as shown below. Figure 4 , Figure 6 and Figure 9 As shown, its two arms transmit a horizontal force F3 to the right and a vertical force F2 to the down.

[0064] In this embodiment, the oblique set screw 71 is threaded into the fixed hinge 1 to provide axial force. The L-shaped force transmission block 72 decomposes the axial force of the oblique set screw 71 into a horizontal rightward component F3 and a vertical downward component F2, which are transmitted to the second adjusting sleeve 6 respectively, forming multi-directional resistance to resist the sagging and outward movement of the hinge 100.

[0065] In this embodiment, the angle between the third direction and the horizontal direction is 45°±5°. This design enables the second adjusting member 7 to generate a horizontal rightward component force F3 and a vertical downward component force F2 simultaneously when force is applied, thereby achieving a balanced distribution of the horizontal and vertical components.

[0066] After the first adjusting member 5 and the second adjusting member 7 are locked, the adjustable gap is reduced or eliminated, forming a multi-directional resistance to the drooping and outward movement of the hinge 100 relative to the fixed door body 110, or a multi-directional resistance to the drooping and disengagement of the movable door body 120 relative to the hinge 100.

[0067] The drooping forms of doors typically include the outward offset and downward deflection of hinge 100 relative to fixed door 110, and the outward offset and downward deflection of movable door 120 relative to hinge 100.

[0068] like Figures 3 to 6As shown, in response to the possible outward and downward deflection of the hinge 100 relative to the fixed door body 110, its anti-sagging adjustment layout and mechanical principle are as follows: On the fixed hinge 1, the first adjustment mechanism acts on the first locking position A, and the first adjustment member 5 is threadedly engaged with the fixed hinge 1. By screwing it in upward along the vertical direction Y, it pushes the plastic sleeve 31 and the metal sleeve 32 to move upward, thereby applying a vertically upward first support force F1 to the first adjustment sleeve 4 of the first locking position A.

[0069] At the same time, the second adjustment mechanism acts on the second locking position B, and the second adjustment member 7 is threaded into the fixed hinge 1. By screwing in along the third direction Z, it pushes the plastic sleeve 31 and the metal sleeve 32, and simultaneously applies a horizontal rightward component force F3 and a vertical downward component force F2 to the second adjustment sleeve 6 at the second locking position B.

[0070] The aforementioned pushing forces F1, F2, and F3 act directly on the locking structure inside the door mounting hole through the adjusting sleeve. According to the principle of mutual force, the door will generate equal and opposite reaction forces on the hinge: the reaction force of the door on the first locking position A is vertically downward, used to resist the downward sag of the hinge 100; the reaction force of the door on the second locking position B is vertically upward and horizontally to the left, used to resist the downward deflection and outward offset of the hinge, respectively.

[0071] Specifically, with the second locking position B stationary, the hinge 100 droops by rotating clockwise around the second locking position B. When the first adjusting mechanism acts on the first locking position A, the vertical set screw 51 is adjusted upwards in the vertical direction Y, and a first vertical upward support force F1 is applied to the metal sleeve 32 of the first locking position A through the wedge-shaped force transmission block 52. At this time, the first adjusting sleeve 4 is locked with the locking screw, and it and the fixed hinge 1 can be regarded as a rigid connection. Since the metal sleeve 32 is tightly fitted with the mounting hole of the fixed door body 110, this force is ultimately applied to the fixed door body 110 through the metal sleeve 32. According to the principle of mutual force, the fixed door body 110 generates a vertically downward reaction force on the metal sleeve 32. This reaction force is transmitted to the first adjusting sleeve 4 and the fixed hinge 1 through the metal sleeve 32, thereby suppressing the clockwise rotation tendency of the hinge 100 around the second locking position B and resisting its drooping relative to the fixed door body 110.

[0072] Similarly, with the first locking position stationary, the drooping form is the hinge 100 rotating clockwise around the first locking position A and shifting to the right relative to the fixed door body 110. Through the oblique set screw 71 threadedly engaging with the fixed hinge 1, adjustment is made in the third direction Z, pushing the L-shaped force transmission block 72 to transmit a horizontal rightward component force F2 and a vertical downward component force F3 to the metal sleeve 32 at the second locking position B. Likewise, considering the second adjustment mechanism and the fixed door body 110 as a rigidly connected whole, the rightward component force F2 and the vertical downward component force F3 ultimately act on the fixed door body 110. According to the principle of mutual force, the fixed door body 110 generates a vertically upward and horizontally leftward force on the metal sleeve 32 at the second locking position B. This reaction force is transmitted to the fixed hinge 1 through the metal sleeve 32 and the second adjustment sleeve 6 to prevent the hinge 100 from drooping relative to the fixed door body 110 and from disengaging outward.

[0073] For the outward offset and downward deflection of the movable door 120 relative to the hinge 100, the adjustment is mainly achieved by the first adjustment mechanism acting on the third locking position C or the fourth locking position D, with the following two embodiments.

[0074] Example 1

[0075] like Figure 3 and Figure 4 As shown, the third locking position C is the direct locking position, and the first adjusting mechanism acts on the fourth locking position D; the first adjusting member 5 is threadedly engaged with the movable hinge 2, and applies a vertically upward second supporting force F4 to the fourth locking position through vertical adjustment in the Y direction.

[0076] Since the third locking position C is a direct locking position, the hinge 100 of the movable door 120 is directly fixed to the movable hinge 2 at the third locking position C. Therefore, the movable door 120 only has a rotational deflection tendency around the relative hinge 100, and its drooping form is a clockwise rotation around point C. When the first adjustment mechanism acts on the fourth locking position, the vertical set screw 51 is adjusted in the vertical direction Y upward, pushing the wedge-shaped force transmission block 52 to transmit the vertically upward second support force F4 to the metal sleeve 32 of the fourth locking position D. This force is ultimately applied to the movable door 120 through the metal sleeve 32. According to the principle of mutual force, the movable door 120 generates a vertically downward reaction force on the metal sleeve 32. This reaction force is transmitted to the movable hinge 2 through the metal sleeve 32, forming a resistance torque that resists the clockwise rotation of the movable door 120 around point C, thereby effectively suppressing its drooping.

[0077] Example 2

[0078] like Figure 5 and Figure 6As shown, the fourth locking position D is a direct locking position, and the first adjusting mechanism acts on the third locking position C; the first adjusting member 5 is threadedly engaged with the movable hinge 2, and applies a vertically downward third clamping force F5 to the third locking position C by adjusting downward in the vertical direction Y.

[0079] Since the fourth locking position D is a direct locking position, the movable door body 120 is directly fixed to the movable hinge 2 at the fourth locking position D. Therefore, the movable hinge 2 has a tendency to rotate and deflect outward relative to the hinge 100 around this point. When the first adjusting mechanism acts on the third locking position C, the vertical set screw 51 is adjusted downward in the vertical direction Y, pushing the wedge-shaped force transmission block 52 to transmit a vertically downward third clamping force F5 to the metal sleeve 32 of the third locking position C. This force ultimately acts on the movable door body 120 through the metal sleeve 32. According to Newton's third law, the movable door body 120 generates a vertically upward reaction force on the metal sleeve 32. This reaction force is transmitted to the movable hinge 2 through the metal sleeve 32, forming a vertical clamping force on the movable hinge 2. Thus, the movable hinge 2 is prevented from disengaging outward relative to the hinge 100. This clamping force simultaneously produces two anti-sagging effects: it enhances the connection rigidity between the movable hinge 2 and the movable door 120 at the third locking position C, resisting the tendency of the movable door 120 to detach outward; and by increasing the frictional torque between the movable hinge 2 and the movable door 120, it suppresses the rotational deflection of the movable door 120 around the fourth locking position D.

[0080] In summary, considering the two sagging scenarios described above, in this embodiment, through the coordinated action of the first and second adjustment mechanisms, the hinge 100 can eliminate the adjustable gap between itself and the fixed door 110 and the movable door 120, forming multi-directional resistance. This effectively resists the sagging and outward movement of the hinge 100 relative to the fixed door 110, as well as the sagging and detachment of the movable door 120 relative to the hinge 100, ensuring the stability and durability of the door. Specifically, the fixed hinge and the movable hinge 2 are provided with multiple locking positions. The first adjustment sleeve 4 is vertically inserted to form the first adjustable gap 10, and the second adjustment sleeve 6 is obliquely inserted to form the second adjustable gap 20. The adjusting member generates multi-directional force through threaded advancement. After locking, the gap is eliminated, forming a rigid connection. This adjustable gap is compatible with initial assembly errors, compensates for manufacturing and installation deviations, and can eliminate assembly gaps that could cause the door to sag after installation. It also adds adjustment function to increase offset resistance in cases where there is a tendency for the door to sag, hindering sagging and improving product stability.

[0081] A type of shower room, such as Figure 10 As shown, the door includes a fixed door body 110, a movable door body 120, and a hinge 100 as described above. There are two hinges 100, which are respectively installed at the upper and lower ends of the door body along the vertical direction Y.

[0082] Specifically, the fixed door body 110 has a horizontally opening X-shaped mounting groove 101 at the position where the hinge 100 is installed to install the hinge 100. The mounting groove 101 accommodates the fixing seat 12 of the fixed hinge 1, facilitating the opening and closing of the movable door body 120. The fixed door body 110 and the movable door body 120 each have two screw holes 109 at four corresponding locking positions near the mounting position, which cooperate with locking screws to lock the fixed hinge 1 and the movable hinge 2.

[0083] In this embodiment, the shower enclosure uses two hinges 100 installed at the top and bottom of the door in the vertical direction to ensure the stability and balance of the movable door 120 during rotation. The anti-sagging adjustment function of the hinges 100 eliminates the torsional stress of the door.

[0084] like Figure 11 and Figure 12 As shown, the shower room can be combined with other fixed doors 110, as well as display racks or walls to form a shower room usage space.

[0085] Specifically, the fixed door 110 is vertically installed on one side of the display rack or wall via the first frame 103; the movable door 120 is rotatably connected to the fixed door 110 via two sets of hinges 100; other fixed doors 110 or walls are vertically installed on the other side of the display rack or wall via the second frame 104. The fixed door 110 has openings between itself and other fixed doors 110 or between itself and the wall, and the movable door 120 is adapted to open and close these openings. In terms of installation structure, the upper and lower edges of the movable door 120 are covered with decorative stainless steel 105, enhancing both aesthetics and protective performance. The lower frame 107 is installed on the ground, tightly fitting into the lower edges of the movable door 120 and the fixed door 110, and forming a sealed connection with the waterproof base; the upper frame 106 is installed on the upper edge of each door, with its two ends firmly fixed to the left and right sides of the display rack or wall, forming a stable top support structure. The movable door 120 is equipped with a door handle 108 to facilitate users in opening and closing the movable door 120.

[0086] In this embodiment, the shower enclosure utilizes the aforementioned hinge to achieve stable opening and closing of the movable door 120 between the fixed door 110 and other fixed doors 110, or between the fixed door 110 and the wall. The anti-sagging and anti-detachment functions of the hinge 100 ensure the flatness and sealing of the hinge 100 and the movable door 120 during long-term use, improving the user experience and safety of the shower enclosure.

Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
