Detailed Description of the Embodiment
[0032] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present embodiment disclosed in the appended claims.
[0033] In practice, as Figures 11 - 13 shown, for this kind of space door (generally composed of a door frame 40 and a door 50) applying the indicating lock 60, during use, due to the human operation habit that the rotation angle of the door lock is often less than 90°, it causes the door lock to be easily not indicated in place, resulting in the following situations: when no one is using it, external people think someone is using it; when someone is using it inside, external people think no one is using it and try to pull the door lock; this embodiment makes improvements on this.
[0034] In one embodiment, please refer to Figures 1 - 10, a combined structure that can be used to switch prompt content. The combined structure includes a housing, an eccentric rotating block 10, an indicating disk 20, and a rotation stopping slider 30;
[0035] An identification area is provided on the first surface of the housing, and a central hole is provided on the second surface;
[0036] The indicating disk 20 is rotatably arranged in the housing, and the rotating shaft of the eccentric rotating block 10 passes through the central hole and is connected to the indicating disk 20 in the housing;
[0037] The rotation stopping slider 30 is relatively arranged on one side of the eccentric rotating block 10 and can be engaged or separated from the eccentric rotating block 10;
[0038] Wherein, when the eccentric rotating block 10 is separated from the rotation stopping slider 30, the eccentric rotating block 10 is affected by its own gravity, and the center of gravity turns to below the rotating shaft; after the rotation stopping slider 30 is engaged with the eccentric rotating block 10, it drives the eccentric rotating block 10 to overcome its own gravity and adjust the center of gravity above the rotating shaft, and the eccentric rotating block 10 correspondingly drives the indicating disk 20 to switch the prompt content in the identification area.
[0039] In an example of this embodiment, the identification area can be a fan-shaped area opened on the housing; the specifications of the fan-shaped area can be flexibly adjusted according to the prompt content, which will not be elaborated here.
[0040] Generally, the first surface of the housing refers to the outer surface, the side of the space door facing the external personnel; the second surface of the housing refers to the inner surface, the side of the space door facing its internal users. Of course, the situation can be reversed in some scenarios.
[0041] In an example of this embodiment, two areas are divided on the indicating disk 20, each occupying a range of 180°; the prompt content can be "occupied", "unoccupied", "busy", "idle", or other similar words, patterns, colors and their combinations, etc.
[0042] In this embodiment, when the combined structure is arranged on the space door, when there is no operation, the eccentric rotating block 10 is affected by its own gravity, and the center of gravity turns to below the rotating shaft. At this time, the corresponding prompt content is "unoccupied"; when there is someone operating, the rotation stopping slider 30 slides and starts to engage with the eccentric rotating block 10, driving the eccentric rotating block 10 to overcome its own gravity and rotate. The eccentric rotating block 10 can adjust the center of gravity above the rotating shaft; at the same time, after the operation of separating the rotation stopping slider 30, the eccentric rotating block 10 can also rely on its own gravity to make the center of gravity turn to below the rotating shaft; correspondingly, it drives the indicating disk 20 to switch to "occupied" for prompting in the identification area; the prompt is clear and accurate without confusion.
[0043] In an example of this embodiment, the shape of the eccentric rotating block 10 is one of an equiangular spiral, an involute spiral, an Archimedean spiral, and a Fibonacci spiral; that is, the eccentric rotating block 10 is one of an equiangular spiral rotating block, an involute spiral rotating block, an Archimedean spiral rotating block, and a Fibonacci spiral rotating block;
[0044] Preferably, an equiangular spiral rotating block is selected in this example.
[0045] In an example of this embodiment, as Figures 5 - 10 shown, the anti-rotation slider 30 is slidably disposed on the door frame 40, and the housing is disposed on the door 50; or, the anti-rotation slider 30 is slidably disposed on the door 50, and the housing is disposed on the door frame 40;
[0046] Among them, the door frame 40 and the door 50 form a space door; the independent space inside the space door can be used by personnel; and the combined structure can prompt external personnel about the usage status of the independent space, such as: occupied, unoccupied, etc.
[0047] For example: The anti-rotation slider 30 is slidably disposed on the door frame 40, and the housing is disposed on the door 50.
[0048] Another example: The anti-rotation slider 30 is slidably disposed on the door 50, and the housing is disposed on the door frame 40.
[0049] In an example of this embodiment, as Figure 1 , Figure 2 shown, the housing includes an inner connector 11 and an outer connector 12; a central hole is provided in the middle of the inner connector 11, and a fan-shaped identification area is provided in the outer connector 12; a connecting stud 13 is provided on the first surface of the inner connector 11, and a connecting hole 14 is provided on the first surface of the outer connector 12, and the connecting stud 13 abuts against the second surface of the outer connector 12 and is connected to the connecting hole 14 by screws.
[0050] In this way, the installation of the combined structure can be carried out conveniently, and the maintenance, update, and disassembly and recycling of the combined structure can also be carried out conveniently.
[0051] In this example, the inner connector 11 and the outer connector 12 can be made of aluminum alloy plates; they can also be made of stainless steel plates, resin plates, etc.
[0052] In an example of this embodiment, different prompt contents are provided on the side of the indicating disk 20 close to the identification area;
[0053] The different prompt contents are, for example: occupied, unoccupied, busy, idle, or other similar words, patterns, colors, and their combinations, etc.
[0054] In this embodiment, the indicating disk 20 is integrally processed with a rotating rod 21, and the rotating rod 21 is connected to the rotating shaft of the eccentric rotating block 10; the eccentric rotating block 10 can drive the indicating disk 20 to rotate; generally, the rotating rod 21 is fixedly connected to the rotating shaft, such as by pin connection, welding, screw connection, or interference fit connection method.
[0055] In an example of this embodiment, as Figure 3 , Figure 4 shown, a slider contact surface 15 is provided on the outer surface of the eccentric rotating block 10, and a locking surface 31 is provided at one end of the anti-rotation slider 30 close to the eccentric rotating block 10, and the locking surface 31 engages or disengages with the slider contact surface 15.
[0056] It can be understood that the rotating surface of the eccentric rotating block 10 and the moving surface when the anti-rotation slider 30 slides are in or close to the same plane.
[0057] In an example of this embodiment, the slider contact surface 15 is a stepped plane, and the locking surface 31 is also a stepped plane.
[0058] In this embodiment, when the eccentric rotating block 10 is adopted, there is a dead point, which is only an optional item; and an equiangular spiral rotating block is preferred.
[0059] As mentioned above, since the equiangular spiral rotating block adopts an asymmetric spiral design, the advantage is that the lines of the spiral structure are continuous, which is beneficial to the smooth contact and engagement between the anti-rotation slider 30 and the equiangular spiral rotating block. Therefore, an equiangular spiral rotating block is preferably adopted. According to the definition of the equiangular spiral: the tangent direction at any point on the spiral is the same as the angle between the tangent point and the center of rotation, that is, any going angle is the same, that is, the normal direction of any tangent point of the equiangular spiral always has the same angle with the axis connection line. The external force in the normal direction at the tangent point is decomposed into a horizontal driving force to provide a driving force for the rotational movement of the rotating shaft.
[0060] From the properties of the equiangular spiral, it can be known that the size of the going angle can control the bending degree of the spiral (the larger the going angle, the smoother the curve, and the smaller the going angle, the more curved the curve). Furthermore, under the condition of reducing the radial space plane size of the spiral, the diameter of the rotating shaft can be increased, which is convenient for improving the strength of the rotating shaft.
[0061] In this example, the slider contact surface 15 can be set to one section, or two sections, or three sections; preferably two sections, namely the first contact surface and the second contact surface.
[0062] Correspondingly, the anti-rotation slider 30 is provided with a first locking plane and a second locking plane, corresponding to the first contact surface and the second contact surface (in Figure 3 ).
[0063] In the above embodiments, the logarithmic spiral rotating block is fixedly connected to the indicating disk 20, and the logarithmic spiral rotating block is an eccentric structure. Under the action of gravity, it will naturally rotate to the lowest center of gravity. Since the indicating range of the indicating disk 20 is 180°, the occupied or unoccupied state can be correctly indicated. Figure 3 , Figure 4 In Figure 4 , when the anti-rotation slider 30 moves linearly until it interferes with the logarithmic spiral rotating block, the anti-rotation slider 30 will drive the logarithmic spiral rotating block to rotate until it is in the engaged state. At this time, the state indication of the combined structure is occupied. After the anti-rotation slider 30 retracts, the indicating disk 20 rotates and resumes the indication of the unoccupied state. This combined structure can be attached to a planar space and has the characteristic of low requirements for a three-dimensional space, demonstrating an example application of a target structure that requires rotational motion when the space in the normal direction of the plane is limited, and is suitable for driving rotational motion by linear motion and locking to assist the indicating function. The anti-rotation slider 30 is provided as a door bolt, which can change an outward-opening door into an inward-opening door, requiring less indoor space and being more convenient to use. It is convenient for existing renovations.
