Description

Technical Field

[0001] The utility model belongs to the technical field of door and window hardware and relates to a hinge structure and a door and window. Background Art

[0002] When the locking point and the lock seat mate, the locking force can be adjusted by rotating the eccentric locking point to adjust the gap or interference between the locking point and the lock seat. To achieve more variable locking force adjustment, the eccentricity of the locking point should theoretically be set relatively large. However, excessive eccentricity can cause the locking point to rotate when subjected to force, leading to loosening over time. Therefore, the range of locking force adjustment based solely on the eccentric locking point is limited and cannot meet user requirements. Utility Model Content

[0007] In some embodiments, the first hole is a circular hole, and the second hole is an elongated hole.

[0008] In some embodiments, the connecting member is a screw.

[0009] In some embodiments, a first sawtooth is provided on a side of the base facing the adjustable member, and a second sawtooth is provided on a side of the adjustable member facing the base, and the first sawtooth is engaged with the second sawtooth.

[0010] In some embodiments, scale lines are provided on the base along the moving direction of the adjustable member.

[0011] In some embodiments, the base has protrusions at both ends, and the adjustable part is located between the two protrusions, for limiting the displacement of the adjustable part in the non-moving direction; wherein the non-moving direction is a direction perpendicular to the moving direction; the scale line is set on the protrusion.

[0012] In some embodiments, the end of the locking point has an eccentric portion, and the transmission rod drives the locking point to move, and can adjust the distance between the eccentric portion and the side surface of the adjustable part.

[0039] Example 1

[0040] This embodiment provides a hinge structure, such as Figure 1-12 As shown, the hinge structure can realize the inward opening and inward tilting opening of the movable part relative to the fixed part. The hinge structure includes a base plate 1 provided on the fixed part, a connecting rod assembly 2 provided on the movable part, a transmission rod, a lock seat 3 and a locking point 4. The lock seat 3 is provided on the base plate 1, the transmission rod is slidably provided on the connecting rod assembly 2, and the locking point 4 is connected to the transmission rod; operating the transmission rod can cause the locking point 4 to engage with or disengage from the lock seat 3;

[0041] Among them, the lock seat 3 includes a base 31 and an adjustable part 32, the base 31 is fixed on the base plate 1, the adjustable part 32 is arranged on the base 31, and the adjustable part 32 can move relative to the base 31 to adjust the fitting clearance between the lock seat 3 and the locking point 4.

[0042] Specifically, Figure 1 and 2 The lock point 4 is disconnected from the lock seat 3. Figure 3-6 The lock point 4 is engaged with the lock seat.

[0043] To address the issue of insufficient locking force adjustment range in existing inward-opening and tilting hinges, this embodiment incorporates an adjustable lock base 3. Specifically, the lock base 3 comprises a base 31 and an adjustable member 32. The base 31 is fixed to the base plate 1. The base 31 primarily secures the lock base 3 to the base plate 1, thereby enabling the lock base 3 to be mounted on the fixed member. The adjustable member 32 primarily adjusts the distance between the lock base 3 and the locking point 4. The connecting rod assembly 2 primarily functions to open and close doors and windows. A transmission rod slidably mounted on the connecting rod assembly 2 is used to switch between inward-opening and tilting positions, primarily through the position of the transmission rod.

[0044] During specific use, driven by the connecting rod assembly 2 and the transmission rod, the locking point 4 can move to the lock seat 3. When the locking point 4 is tangent to the lock seat 3, in this embodiment, the locking point 4 is tangent to the side of the adjustable part 32, thereby achieving the engagement between the locking point 4 and the lock seat 3, that is, achieving locking.

[0045] If the locking force needs to be reduced, the adjustable member 32 is moved in a first direction to increase the clearance between the adjustable member 32 and the locking point 4. If the locking force needs to be increased, the adjustable member 32 is moved in a second direction to achieve an interference fit with the locking point 4. The first direction is the direction away from the locking point 4, and the second direction is the direction toward the locking point 4.

[0046] The hinge structure provided in this embodiment realizes the adjustment of the locking force through the lock seat 3 composed of the base 31 and the adjustable part 32, so that the hinge structure can adapt to a wider range of profiles and rubber strips and can meet the different sealing requirements of different users.

[0047] In a specific embodiment, the lock seat 3 also includes a connecting member 33; a first hole 311 is opened on the base 31, and a second hole 321 is opened on the adjustable member 32, and in the moving direction of the adjustable member 32, the length of the second hole 321 is greater than the length of the first hole 311, so that after the adjustable member 32 moves, the connecting member 33 can fix the base 31 and the adjustable member 32 through the first hole 311 and the second hole 321.

[0048] Specifically, the connecting member 33 is used to connect the base 31 and the adjustable member 32. To achieve this connection, a first hole 311 is formed on the base 31, and a second hole 321 is formed at an opposite position on the adjustable member 32. The connecting member 33 then passes through the second hole 321 and the first hole 311 in sequence to achieve the connection between the two.

[0049] It should also be noted that in the moving direction of the adjustable member 32, the length of the second hole 321 is greater than the length of the first hole 311. Only in this way can the second hole 321 and the first hole 311 still have enough space for the connecting member 33 to pass through after the adjustable member 32 is adjusted.

[0050] In a specific embodiment, the first hole 311 is a circular hole, and the second hole 321 is an elongated hole. A circular hole is machined in the middle of the base 31, and an elongated hole is machined in the middle of the adjustable member 32, thereby achieving the two being matched. In addition, the connecting member 33 is a screw.

[0051] In a specific embodiment, the base 31 is provided with first serrations 312 on a side facing the adjustable member 32, and the adjustable member 32 is provided with second serrations 322 on a side facing the base 31. The first serrations 312 engage with the second serrations 322. Specifically, the base 31 and the adjustable member 32 are mated together by the first serrations 312 and the second serrations 322, preventing them from slipping when subjected to force, which could affect the locking effect.

[0052] In a specific embodiment, scale lines 313 are provided on the base 31 along the moving direction of the adjustable member 32. The provision of the scale lines 313 allows the user to make adjustments more conveniently.

[0053] In a specific embodiment, the base 31 has protrusions 314 at both ends, and the adjustable member 32 is located between the two protrusions 314, which are used to limit the displacement of the adjustable member 32 in a non-moving direction; wherein the non-moving direction is a direction perpendicular to the moving direction; the scale lines 313 are provided on the protrusions 314. The provision of the protrusions 314 can prevent the adjustable member 32 from moving in the non-moving direction and separating from the base 31.

[0054] In a specific embodiment, the end of the locking point 4 has an eccentric portion, and the transmission rod drives the locking point 4 to move, so as to adjust the distance between the eccentric portion and the side surface of the adjustable component 32 .

[0055] When the position of the adjustable member 32 is adjusted to the extreme positions on both sides and still cannot meet the use requirements, the locking point 4 can be adjusted to compensate for the insufficient adjustment amount.

[0056] The hinge structure provided in this embodiment can adjust the locking force, making it adaptable to a wider range of profiles and rubber strips, and can meet the different sealing requirements of different users. For example, if the sealing requirements are not high, the locking force can be increased, and if the sealing requirements are high, the locking force can be reduced. Specifically:

[0057] like Figure 10 The figure shows the initial state after the lock point 4 and the lock seat 3 are matched. In this state, the lock point 4 is tangent to the lock seat 3, and the lock seat has not been adjusted for eccentricity. Figure 11 The above is a state in which the locking point 4 and the lock seat 3 are matched and the locking force is relatively large. In this state, the locking point 4 and the lock seat 3 are interference-fitted. That is, by operating the adjustable part 32, it is moved in the direction close to the locking point 4, thereby making the two interference-fitted. This state is suitable for areas or users with high requirements for sealing. Figure 11 The figure shows a state in which the locking force is relatively small after the locking point 4 and the lock seat 3 are matched. In this state, the locking point 4 and the lock seat 3 are loosely matched, that is, by operating the adjustable part 32, it is moved away from the locking point 4, so that a gap is formed between the two. This state is suitable for areas or users with low requirements for sealing.

[0058] Of course, during the above operation, if adjusting the lock seat 3 closely does not meet the requirements, the lock point 4 can be combined for adjustment.

[0059] The hinge structure provided in this embodiment integrates an adjustable lock seat into the inward-opening and inward-tilting hinge, and adjusts the pressing force of the fan body on the frame body when locked by changing the distance between the lock seat and the locking point.

[0060] Example 2

[0061] This embodiment provides a door and window, which includes the hinge structure described in Example 1.

[0062] In a specific embodiment, the door and window includes a fan body and a frame body, the lock seat 3 is arranged on the frame body through the bottom plate 1, and the locking point 4 is arranged on the fan body through the transmission rod.

[0063] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0064] The above are merely preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
