Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hinges, in particular to a slow-collapsible hinge. Background Art
[0002] A hinge is a device that connects two objects, usually consisting of two metal pieces connected together by an axis. A hinge allows an object to rotate around a fixed axis, such as a door or window. Hinges are widely used in furniture, doors, windows, vehicles and other fields, and are a very common connection device.
[0003] However, in the prior art, when the existing hinges are in use, if the angle is subject to the maximum limit, the hinges may be squeezed and deformed under the influence of external forces, and their structural strength may be affected, thereby increasing the risk of hinge breakage or damage, thereby affecting the normal operation of the device. Once the hinge is deformed or damaged, its normal rotation function may be affected, resulting in the blade being unable to rotate correctly within the designed range, which will directly affect the performance and efficiency of the device. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a slow-collapsible hinge.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a slow-speed collapsible hinge, comprising: a collapsing mechanism, a limiting mechanism is arranged on the top of the collapsing mechanism, the collapsing mechanism comprises a wall panel, a fixed plate is arranged on one side of the wall panel, a hollow ring is arranged on the outer side of the fixed plate, an arc block is arranged inside the hollow ring, a center roller is arranged at one end of the arc block, and a hollow ring is arranged on the outer side of the center roller.
[0006] As a preferred embodiment, an inner plate is provided on the outer side of the arc block, an outer ring is provided on the outer side of the inner plate, a blade is provided on one side of the outer ring, an iron plate is provided on the bottom side of the hollow ring, an iron magnet is provided at the bottom of the iron plate, and a wall panel is provided on the outer side of the iron magnet.
[0007] As a preferred implementation, the limiting mechanism comprises a limiting rod, a ball head is arranged on the top of the limiting rod, and the bottom of the limiting rod is fixedly connected to the top of the wall panel.
[0008] As a preferred embodiment, one side of the wall panel is fixedly connected to one side of the fixing plate, the outer side of the fixing plate is fixedly connected to the inner surface of the hollow ring, and the inner surface of the hollow ring contacts the outer side of the arc block.
[0009] As a preferred implementation, one end of the arc block is fixedly connected to one end of the center roller, and the outer side of the center roller is fixedly connected to the inner surface of the hollow ring.
[0010] As a preferred embodiment, the outer side of the arc block is movably connected to the inner surface of the inner plate, the outer side of the inner plate is fixedly connected to the inner surface of the outer ring, and the outer side of the outer ring is fixedly connected to one end of the blade.
[0011] As a preferred implementation, the bottom side of the hollow ring is fixedly connected to the inner side of the iron plate, and the outer side of the iron plate corresponds vertically to the surface of the magnetic block.
[0012] As a preferred implementation manner, the outer side of the magnetic block is fixedly connected to the inner wall of the wall panel.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] The utility model installs a collapse mechanism, which, under certain circumstances, will exert pressure on the outer ring and cause extrusion when a large pressure is exerted on the blade. At the same time, the inner ring will exert pressure on the arc block in the same way, forcing the arc block to deform without causing damage to the hinge. Therefore, even if the blade exerts a large pressure, the hinge can still maintain its functional integrity to ensure the normal operation of the device.

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.
[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0026] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.
[0027] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0028] Example 1
[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a slow-speed collapsible hinge, comprising: a collapsing mechanism 1, a limiting mechanism 2 is arranged on the top of the collapsing mechanism 1, the collapsing mechanism 1 comprises a wall panel 11, a fixed plate 12 is arranged on one side of the wall panel 11, a hollow ring 13 is arranged on the outer side of the fixed plate 12, an arc block 16 is arranged inside the hollow ring 13, a center roller 15 is arranged at one end of the arc block 16, a hollow ring 13 is arranged on the outer side of the center roller 15, an inner plate 17 is arranged on the outer side of the arc block 16, an outer ring 14 is arranged on the outer side of the inner plate 17, a blade 18 is arranged on one side of the outer ring 14, an iron plate 110 is arranged on the bottom side of the hollow ring 13, an iron magnet 19 is arranged on the bottom of the iron plate 110, and the wall panel 11 is arranged on the outer side of the iron magnet 19.
[0030] In this embodiment, when the modified hinge is in use, an external force is applied to the blade 18 so that the outer ring 14 is rotated on the hollow ring 13, and the rotation angle of the hinge is limited to a certain extent. Therefore, when it rotates to a certain angle, the blade 18 will stop rotating. For example, in certain circumstances, when a large pressure is applied to the blade 18, pressure will be applied to the outer ring 14, causing extrusion. At the same time, the inner ring will apply pressure to the arc block 16 in the same way, forcing the arc block 16 to deform without causing damage to the hinge. Therefore, even if the blade 18 generates a large pressure, the hinge can still maintain its complete function and ensure the normal operation of the device.
[0031] Secondly, when the blade 18 is reset, the iron sheet at the bottom of the hollow ring 13 can generate magnetic force with the magnetic block 19 during the reset process, thereby enhancing the reset force of the blade 18. The magnetic force can provide a buffering effect during the reset process of the blade 18, making the movement of the blade 18 smoother and more stable, which helps to avoid the impact and vibration caused by the excessively fast reset speed of the blade 18, thereby protecting the device and the blade 18 itself from damage.
[0032] Example 2
[0033] like Figure 1-2 As shown, the limiting mechanism 2 includes a limiting rod 21 , a ball head 22 is provided on the top of the limiting rod 21 , and the bottom of the limiting rod 21 is fixedly connected to the top of the wall panel 11 .
[0034] In this embodiment, when the blade 18 rotates to a preset angle, the ball head 22 on the limit rod 21 will contact a specific position, which the operator will feel as a warning signal to remind the operator that the blade 18 has reached the limit position. This helps to prevent the blade 18 from over-rotating or exceeding the design range. Therefore, by preventing the blade 18 from continuing to rotate, possible accidents can be avoided, thereby improving the reliability and safety of the device.
[0035] Working principle:
[0036] like Figure 1-4 As shown, by applying external force to the blade 18, the outer ring 14 is rotated on the hollow ring 13, and the rotation angle of the hinge is limited to a certain extent. Therefore, when it rotates to a certain angle, the blade 18 will stop rotating. For example, under certain circumstances, when a large pressure is applied to the blade 18, pressure will be exerted on the outer ring 14, and extrusion will be caused. At the same time, the inner ring will exert pressure on the arc block 16 in the same way, forcing the arc block 16 to deform without causing damage to the hinge. Secondly, when the blade 18 is reset, the iron sheet at the bottom of the hollow ring 13 installed can generate magnetic force with the magnetic block 19 during the reset process, thereby enhancing the reset force of the blade 18, and the effect of the magnetic force can provide a buffering effect during the reset process of the blade 18, so that the movement of the blade 18 is smoother and more stable.
[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
[0038] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
