Description

Technical Field

[0001] The present invention relates to the field of deceleration, and particularly to a deceleration device in a manual-automatic integrated intelligent smoke exhaust system. Background Art

[0002] Existing deceleration devices generally include moving parts and deceleration blocks. When it is necessary to decelerate the moving parts, the deceleration blocks are moved towards the moving parts and come into contact with the moving parts, thereby decelerating the moving parts. However, when the moving parts rotate at a high speed and come into contact with the deceleration blocks, the speed of the moving parts often drops rapidly, and it is impossible to perform corresponding deceleration according to the existing speed of the moving parts.

[0003] Therefore, existing deceleration devices need to be further improved to be able to automatically decelerate the moving parts according to the different current moving speeds of the moving parts. Summary of the Invention

[0004] To achieve the above object, the present invention provides a deceleration device, which includes a deceleration wear-resistant sheet and a deceleration mechanism. The deceleration wear-resistant sheet has a hollow portion. The deceleration mechanism is disposed in the hollow portion of the deceleration wear-resistant sheet. The deceleration mechanism includes a rotating body and at least two deceleration blocks. The rotating body is capable of rotating relative to the deceleration wear-resistant sheet. The at least two deceleration blocks are arranged around the rotating body and are slidably connected to the rotating body. Wherein, the at least two deceleration blocks are capable of contacting the deceleration wear-resistant sheet.

[0005] Further, the at least two deceleration blocks are configured such that when the at least two deceleration blocks are away from the rotating body, the at least two deceleration blocks are capable of contacting the deceleration wear-resistant sheet.

[0006] Further, the rotating body has a rotation axis, and the rotating body and the at least two deceleration blocks are capable of rotating around the rotation axis. Each of the at least two deceleration blocks slides relative to the rotating body in the radial direction of the rotating body, wherein the radial direction is perpendicular to the rotation axis.

[0007] Further, the deceleration mechanism further includes at least two guide members, each of the at least two guide members is arranged in the radial direction of the rotating body and is correspondingly arranged with a corresponding one of the at least two deceleration blocks. Wherein, each of the at least two deceleration blocks is provided with a first guide member receiving hole, the rotating body is provided with a second guide member receiving hole, one end of each of the at least two guide members is received in the first guide member receiving hole, and the other end of each of the at least two guide members is received in the second guide member receiving hole.

[0008] Further, the rotating body is a cylinder, each of the at least two deceleration blocks is a sector cylinder, the first guide member receiving hole is provided on the inner side wall of the sector cylinder, and the second guide member receiving hole is provided on the outer side wall of the rotating body.

[0009] Further, the deceleration mechanism further includes a deceleration elastic member, the deceleration elastic member is disposed around the at least two deceleration blocks, and is capable of applying a force towards the rotating body to the at least two deceleration blocks.

[0010] Further, the deceleration elastic member is annular, and an elastic body receiving portion is provided on the outer side wall of each of the at least two deceleration blocks for receiving at least a part of the deceleration elastic member.

[0011] Further, the at least two deceleration blocks are made of metal, and the deceleration wear-resistant sheet is made of non-metal.

[0012] The present application further provides a manual and automatic integrated intelligent smoke exhaust system, which includes the above deceleration device.

[0013] Further, the above deceleration device further includes a transmission gear, the transmission gear is connected to the rotating body, and is capable of rotating together with the rotating body. The manual and automatic integrated intelligent smoke exhaust system further includes a storage wheel and at least one planetary gear. The storage wheel has an internal gear ring. Each of the at least one planetary gears is disposed around the rotating body, and each of the at least one planetary gears meshes with the transmission gear and the internal gear ring of the storage wheel.

[0014] The deceleration mechanism in the manual and automatic integrated intelligent smoke exhaust system of the present invention can adapt to the movement speed of the handle to slow down the rotation speed of the storage wheel. In other words, when the rotation speed of the storage wheel is slow, the deceleration mechanism does not decelerate the storage wheel. When the rotation speed of the handle is fast, the deceleration mechanism decelerates the storage wheel, and when the rotation speed of the storage wheel is faster, the force of the four deceleration blocks against the deceleration wear-resistant sheet is greater, and the frictional force generated by the deceleration wear-resistant sheet on it is also greater. Correspondingly, the degree of deceleration of the deceleration mechanism to the storage wheel is greater.

[0032] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0034] Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following drawings, the same components are denoted by the same reference numerals. Although terms indicating directions such as "upper", "lower", etc. are used in the present invention to describe the embodiments, these terms are used only for convenience of explanation and are determined based on the exemplary orientations shown in the drawings. Since the disclosed embodiments of the present invention can be arranged in different directions, these terms indicating directions are for illustration only and should not be construed as limitations.

[0035] Ordinal numbers such as "first", "second", etc. used in this application are only for distinction and identification and do not have any other meanings. Without special indication, they do not represent a specific order and do not have a specific relevance. For example, the term "first cover" itself does not imply the existence of a "second cover", and the term "second cover" itself does not imply the existence of a "first cover".

[0036] As Figure 1 shown, a manual-automatic integrated intelligent smoke exhaust system is provided in the building 1. The manual-automatic integrated intelligent smoke exhaust system includes a smoke exhaust device and a rope control device. Specifically, a window opening is provided in the upper part of the side wall of the building 1 for arranging the smoke exhaust device. The smoke exhaust device includes a fixed window frame 2 and a movable window 3. The fixed window frame 2 is arranged in the window opening and fixedly connected to the side wall. The movable window 3 is arranged in the fixed window frame 2 and can move relative to the fixed window frame 2. The movable window 3 has a closed position and an open position. When the movable window 3 is in the closed position, the movable window 3 is flush with the fixed window frame 2 so that the inner and outer spaces (i.e., indoor and outdoor) of the side wall of the building 1 are not communicated through the window opening. When the movable window 3 is in the open position, the movable window 3 is arranged at an angle with the fixed window frame 2 so that an opening is formed between the movable window 3 and the fixed window frame 2, and the inner and outer spaces of the side wall of the building 1 can be communicated through the opening.

[0037] As Figure 1 shown, a rope control device is provided on the side wall of the building 1 for accommodating and controlling the rope 5. The rope 5 is configured such that when the rope 5 is tightened, the movable window 3 can move from the open position to the closed position; when the rope 5 is released, the movable window 3 can move from the closed position to the open position. In this application, the rotating shaft (not shown) of the handle 4 can be inserted into the second end hollow part 417 of the rope control device (see Figure 2 ). When the user rotates the handle 4, the rope control device can release or tighten the rope 5. Those skilled in the art can understand that the rope 5 in the present invention can be various ropes such as steel ropes.

[0038] As Figures 2 - 6As shown in the figure, the rope control device of the present invention includes a base 10, a storage wheel 40, a speed reduction device, a speed reduction wear-resistant piece 55, a limiting device, a starting device, a first cover 21, a second cover 22 and a third cover 23. Among them, the base 10 is used to carry the storage wheel 40, the speed reduction device, the speed reduction wear-resistant piece 55, the limiting device 60 and the starting device. The first cover 21, the second cover 22 and the third cover 23 are covered on the base 10 to protect the components accommodated in the base 10. The storage wheel 40 is used to store the rope 5 and can control the release or tightening of the rope 5. The speed reduction device is arranged between the base 10 and the storage wheel 40 to adjust the rotation speed of the storage wheel 40. The limiting device 60 is used to limit the storage wheel 40. The limiting device 60 has a first position and a second position. When the limiting device 60 is in the first position, the storage wheel 40 can only rotate in the clockwise direction. When the limiting device 60 is in the second position, the storage wheel 40 can rotate in the clockwise direction or in the counterclockwise direction. The starting device is used to control the limiting device 60 to move from the first position to the second position.

[0039] The following will describe the specific structures of the components of the rope control device of the present invention in conjunction with Figures 2 - 15 the following:

[0040] As Figures 2 - 6 shown in the figure, the base 10 defines a base cavity 11. The upper part of the base cavity 11 is generally circular, and the lower part is generally rectangular, and the circular part in its upper part has a central axis X. The base cavity 11 is used to accommodate the storage wheel 40 and the speed reduction device 50. A speed reduction wall 111 is provided in the base cavity 11. The speed reduction wall 111 is generally an annular ring, and it is coaxially arranged with the circular cavity in the upper part of the base cavity 11. That is to say, the speed reduction wall 111 also has a central axis X. The speed reduction wall 111 has a hollow part for accommodating the speed reduction mechanism 51 and the speed reduction wear-resistant piece 55. The speed reduction wear-resistant piece 55 and the speed reduction mechanism 51 form a speed reduction device.

[0041] As Figures 2 - 8As shown, the storage wheel 40 includes a storage wheel body 41, a bushing 414, and a pin 412. The storage wheel body 41 is generally cylindrical and has a storage wheel axis. When the storage wheel 40 is assembled in place with the base 10, the storage wheel axis is coaxially arranged with the central axis X. A rope receiving portion 43 is provided on the circumferential side wall of the storage wheel body 41, which is formed by recessing from the circumferential side wall of the storage wheel body 41 towards the storage wheel axis. The rope receiving portion 43 is used to receive the rope 5. A first pin hole 46 is provided on the circumferential side wall of the storage wheel body 41 for receiving the pin 412. An external gear ring 42 is provided at the left end of the circumferential side wall of the storage wheel body 41. The external gear ring 42 is configured to enable the left part of the storage wheel body 41 to form a ratchet, and this ratchet can cooperate with the limiting member 63 in the limiting device 60. More specifically, each tooth in the external gear ring 42 has a first tooth surface 112 and a second tooth surface 113. The first tooth surface 112 extends substantially along the radial direction of the storage wheel body 41. The second tooth surface 113 is arranged at an acute angle with the free end of the first tooth surface 112, and in the clockwise direction, the second tooth surface 113 is located downstream of the first tooth surface 112. The limiting device 60 has a first position and a second position. When the limiting device 60 is in the first position, the free end of the limiting member 63 contacts the external gear ring 42, so that the storage wheel 40 can only rotate clockwise around the central axis X. When the limiting device 60 is in the second position, the limiting member 63 does not contact the external gear ring 42, so that the storage wheel 40 can rotate clockwise or counterclockwise around the central axis X.

[0042] It should be noted that in the example of the present invention, when the storage wheel 40 rotates clockwise around the central axis X, the rope 5 is tightened, and when the storage wheel 40 rotates counterclockwise around the central axis X, the rope 5 is released.

[0043] As Figures 2 - 8As shown, the receiving wheel cavity 45 runs through the receiving wheel body 41 along the axis of the receiving wheel. A vertically arranged partition plate 47 is provided in the receiving wheel cavity 45 to divide the receiving wheel cavity 45 into left and right parts. The left part of the receiving wheel cavity 45 is used to accommodate the planetary mechanism 52. The partition plate 47 has a through hole coaxial with the axis of the receiving wheel for receiving the bushing 414. An internal gear ring 44 is provided at the left end of the side wall of the receiving wheel cavity 45 for meshing with the first planetary gear 611 and the second planetary gear 612 in the planetary mechanism 52. The bushing 414 is generally cylindrical and is coaxially arranged with the receiving wheel body 41 in the receiving wheel cavity 45. Both ends of the bushing 414 have inwardly recessed hollow parts. Among them, the first end hollow part 416 is used to receive the rotating rod 502, and the second end hollow part 417 is used to receive the rotating shaft (not shown) of the handle 4. The bushing 414 has a vertically penetrating second pin hole 415 for receiving the pin 412. After the bushing 414 passes through the through hole on the partition plate 47, the pin 412 passes through the first pin hole 46 and the second pin hole 415 to hold the pin 412 in place. When the bushing 414 rotates, the receiving wheel 40 also rotates. In other words, the rotation of the handle 4 can drive the rotation of the receiving wheel 40.

[0044] As Figure 9 shown, the planetary mechanism 52 is accommodated in the left part of the receiving wheel cavity 45. The planetary mechanism 52 includes a bracket 610 and two planetary gears (i.e., the first planetary gear 611 and the second planetary gear 612). The first planetary gear 611 and the second planetary gear 612 are arranged on the same side of the bracket 610 and are connected to the bracket 610. A through hole 613 is provided on the bracket 610 so that the transmission gear 503 in the speed reduction mechanism 51 can pass through the through hole 613 from the rear side of the bracket 610 and mesh with the first planetary gear 611 and the second planetary gear 612. In addition, the first planetary gear 611 and the second planetary gear 612 also mesh with the internal gear ring 44 in the receiving wheel 40.

[0045] As Figures 2 - 13As shown, the speed reduction device includes a speed reduction mechanism 51, which is accommodated in a cavity (i.e., the hollow part) surrounded by the speed reduction wall 111. The speed reduction wear-resistant piece 55 is generally annular. It is arranged in the hollow part and closely adheres to the speed reduction wall 111. The speed reduction wear-resistant piece 55 is coaxially arranged with the speed reduction wall 111. The speed reduction mechanism 51 includes a rotating member 53 and a speed reduction assembly 54. The rotating member 53 includes a rotating main body 501, a rotating rod 502, and a transmission gear 503. Among them, the rotating main body 501 is generally cylindrical and has a rotation axis. The rotating main body 501 is coaxially arranged with the speed reduction wear-resistant piece 55. Four second guide member receiving holes 504 evenly distributed along the circumferential direction are provided on the side wall of the rotating main body 501, respectively for receiving four guide members 521. The rotating rod 502 is coaxially arranged with the rotating main body 501. The end of the rotating rod 502 is received by the first end hollow part 416 of the receiving wheel 40, and the rotating rod 502 can rotate relative to the bushing 414. The transmission gear 503 is arranged on the rotating rod 502 so that the rotation of the transmission gear 503 can drive the rotation of the rotating main body 501.

[0046] The speed reduction assembly 54 includes four speed reduction blocks 511, four guide members 521, and a speed reduction elastic member 531. The four speed reduction blocks 511 are arranged around the rotating main body 501. The specific structure of each of the four speed reduction blocks 511 is the same. Specifically, the speed reduction block 511 is generally a sector-shaped column. It has an arc-shaped outer side wall 514 and an inner side wall 515. The radian of the inner side wall 515 is the same as the radian of the side wall of the rotating main body 501. A first guide member receiving hole 513 is provided on the speed reduction block 511. The first guide member receiving hole 513 extends from the inner side wall 515 radially outward to the outer side wall 514 for receiving the guide member 521. An elastic body receiving portion 512 is also provided on the speed reduction block 511. The elastic body receiving portion 512 extends from the outer side wall 514 circumferentially inward to the inner side wall 515 for receiving a part of the speed reduction elastic member 531. The specific structure of each of the four guide members 521 is the same. Specifically, the guide member 521 is generally a cylinder, one end of which is received in the second guide member receiving hole 504 of the rotating main body 501, and the other end is received in the first guide member receiving hole 513, so that the four speed reduction blocks 511 are movably connected to the rotating member 53. When the rotating member 53 and the speed reduction assembly 54 are assembled in place, the four speed reduction blocks 511 can move relative to the rotating member 53 along the four guide members 521 respectively. The speed reduction elastic member 531 is annular. It surrounds the four speed reduction blocks 511 and is received in the elastic body receiving portions 512 on the four speed reduction blocks 511.

[0047] When the speed reduction mechanism 51, the planetary mechanism 52, and the storage wheel 40 are assembled in place, the user rotates the handle 4, and the handle 4 drives the storage wheel 40 to rotate. Since the internal gear ring 44 in the storage wheel 40 meshes with the first planetary gear 611 and the second planetary gear 612, and the first planetary gear 611 and the second planetary gear 612 mesh with the transmission gear 503, when the storage wheel 40 rotates, the internal gear ring 44 of the storage wheel 40 rotates, thereby driving the two planetary gears to rotate. The rotation of the two planetary gears drives the transmission gear 503 in the speed reduction mechanism 51 to rotate, thereby causing the rotating body 501 to rotate. When the user rotates the handle 4, the rotation speed of the storage wheel 40 is the same as the speed at which the user rotates the handle 4. The two planetary gears can accelerate the rotation of the transmission gear 503, so that the rotation speed of the transmission gear 503 is greater than the rotation speed of the storage wheel 40.

[0048] The speed reduction principle of the speed reduction assembly 54 is based on the rotation speed of the transmission gear 503. The following refers to Figures 12 - 13 to describe the speed reduction principle of the speed reduction assembly 54:

[0049] Figure 12 FIG. is a state diagram of the rotating member 53 in the speed reduction mechanism 51 rotating at a low speed. As Figure 12 shown, the rotating member 53 and the four speed reduction blocks 511 are rotating at a low speed. While the four speed reduction blocks 511 are rotating, they are subject to centrifugal forces and move away from the rotating member 53 along the four guide members 521 respectively. The speed reduction elastic member 531 is opened by the four speed reduction blocks 511 moving away from the rotating member 53. The deformed speed reduction elastic member 531 generates a contracting force on the four speed reduction blocks 511 towards the rotating member 53. At this time, the four speed reduction blocks 511 are held in place under the action of centrifugal forces and contracting forces in opposite directions. Since the rotation speed of the rotating member 53 is relatively slow, the four speed reduction blocks 511 have not yet contacted the speed reduction wear-resistant sheet 55. The rotating member 53 can maintain its own rotation speed. At this time, the speed at which the user rotates the handle 4 is the true rotation speed of the handle 4.

[0050] Figure 13 FIG. is a state diagram of the rotating member 53 in the speed reduction mechanism 51 rotating at a high speed. As Figure 13As shown, the rotating member 53 and the four deceleration blocks 511 are rotating at high speed. While the four deceleration blocks 511 are rotating, they are subject to centrifugal force and move away from the rotating member 53 along the four guiding members 521 respectively. The deceleration elastic member 531 is opened by the four deceleration blocks 511 moving away from the rotating member 53. Since the four guiding members 521 rotate relatively fast around the axis 202, the centrifugal force received by the four guiding members 521 is greater than the contraction force generated by the deceleration elastic member 531, and the four deceleration blocks 511 contact the deceleration wear-resistant piece 55. The four deceleration blocks 511 contacting the deceleration wear-resistant piece 55 are subject to the frictional force exerted on them by the deceleration wear-resistant piece 55, which causes the rotation of the four deceleration blocks 511 around the axis of the axis 202 to slow down. Since the four deceleration blocks 511 are respectively connected to the rotating member 53 through the four guiding members 521 in a relatively movable manner, the slowdown of the rotation of the four deceleration blocks 511 will also slow down the rotation of the rotating member 53. Thus, the rotation speed of the rotating member 53 is reduced. The rotating member 53 with a reduced rotation speed restricts the rotation of the storage wheel 40, so that the user feels a greater rotational resistance. At this time, although the user rotates the handle 4, the user will feel the rotational resistance, so that the user rotates the handle 4 more slowly.

[0051] The deceleration mechanism 51 in the rope control device of the present invention can adapt to the movement speed of the handle 4 to slow down the rotation speed of the storage wheel 40. That is to say, when the rotation speed of the handle 4 is slow, the deceleration mechanism 51 does not decelerate the storage wheel 40. When the rotation speed of the handle 4 is fast, the deceleration mechanism 51 decelerates the storage wheel 40, and when the rotation speed of the handle 4 is faster, the greater the force of the four deceleration blocks 511 against the deceleration wear-resistant piece 55, the greater the frictional force generated by the deceleration wear-resistant piece 55 on it, and correspondingly, the greater the degree of deceleration of the deceleration mechanism 51 on the storage wheel 40.

[0052] As an example, the deceleration wall 111 and the deceleration blocks 511 are made of metal. The deceleration wear-resistant piece 55 is made of non-metal. The hardness of this non-metal is lower than that of the metal. When the deceleration wear-resistant piece 55 moves relative to the deceleration blocks 511, due to the lower hardness of the non-metal, it will wear during friction, thus protecting the deceleration wall 111 and the deceleration blocks 511 to extend the service life of the rope control device.

[0053] It should be noted that although four deceleration blocks 511, four guiding members 521 and the corresponding four second guiding member receiving holes 504 and four second receiving holes 403 are shown in the present application, those skilled in the art can understand that at least two deceleration blocks 511 and the guiding members 521, second guiding member receiving holes 504 and second receiving holes 403 with a matching number are all within the protection scope of the present invention.

[0054] It should also be noted that although two planetary gears are shown in the present application, those skilled in the art can understand that at least one planetary gear is within the protection scope of the present invention.

[0055] As Figures 2 - 6 and Figures 14 - 15 shown, the starting device and the limiting device 60 are accommodated in the rectangular cavity at the lower part of the base 10. The limiting device 60 includes a limiting seat 61, a limiting member 63, a first elastic member 64, a limiting linkage rod 68, and a second elastic member 69. Among them, the limiting seat 61 is rotatably connected to the base 10 through a first rotating shaft 621. The first end of the limiting member 63 is rotatably connected to the base 10 through a second rotating shaft 622. The second end of the limiting member 63 is a free end for contacting the outer gear ring 42 to limit the rotation direction of the receiving wheel 40. The first elastic member 64 is used to provide a force for the limiting member 63 to press against the outer gear ring 42. Specifically, one end of the first elastic member 64 is connected to the limiting seat 61, and the other end of the first elastic member 64 is connected to the limiting member 63. When the limiting device 60 is in the first position, the first elastic member 64 can hold the limiting member 63 in place so that the receiving wheel 40 can only rotate in the clockwise direction. The limiting linkage rod 68 is arranged substantially in the up and down direction. The first end (i.e., the upper end) of the limiting linkage rod 68 is connected to the limiting seat 61 so that when the limiting device 60 rotates around the first rotating shaft 621, the limiting linkage rod 68 can rotate around the first rotating shaft 621 together. One end of the second elastic member 69 is connected to the lower part of the limiting linkage rod 68, and the other end is connected to the base 10 for providing a driving force for the movement of the limiting device 60 from the first position to the second position. Specifically, when the limiting device 60 is in the first position, the second elastic member 69 is in a stretched state.

[0056] As Figures 14 - 15 shown, a reset rod 67 is further provided on the limiting device 60. The reset rod 67 is arranged perpendicular to the plane where the base 10 is located. Specifically, one end of the reset rod 67 is connected to the limiting seat 61, and the other end is a free end for the user to toggle. In the present invention, the reset rod 67 can pass through the third cover through hole of the third cover 23 for the user to operate conveniently.

[0057] As Figures 3 - 6As shown, the starting device includes an electric starting device, a manual starting device, and a starting linkage rod 81. The electric starting device includes a motor. The motor has a motor body 71 and an output rod 72. The output rod 72 is capable of moving relative to the motor body 71. The output rod 72 has an initial position of the output rod and a predetermined position of the output rod. When the motor is started, the output rod 72 can move upward relative to the motor body 71 and reach the predetermined position of the output rod from the initial position of the output rod. After reaching the predetermined position of the output rod, the output rod 72 can move downward relative to the motor body 71 and return to the initial position of the output rod. The manual starting device includes a pressing member 73, a starting rod 74, and a third elastic member 75. Specifically, referring to Figure 4 As shown, the pressing member 73 is arranged perpendicular to the plane where the base 10 is located. The middle part of the pressing member 73 is an inclined part, and the right end is a thinner free end. The starting rod 74 is arranged substantially in the up and down direction and has an initial position of the starting rod and a predetermined position of the starting rod. There is a hole 76 on the starting rod 74. The free end of the pressing member 73 is received in the hole 76. The third elastic member 75 is arranged between the pressing member 73 and the starting rod 74 so that the pressing member 73 is away from the starting rod 74. The inclined part in the pressing member 73 cooperates with the hole 76 on the starting rod 74 so that when the user presses the pressing member 73, the movement of the pressing member 73 towards the starting rod 74 drives the starting rod 74 to move upward and reach the predetermined position of the starting rod. The third elastic member 75 is configured such that when the user releases the pressing member 73, the third elastic member 75 applies a force to the pressing member 73, thereby causing the pressing member 73 to move away from the starting rod 74 and the starting rod 74 to move downward to the initial position of the starting rod. The starting linkage rod 81 is arranged at the lower part of the base cavity 11 and is substantially parallel to the bottom edge of the base cavity 11. The starting linkage rod 81 is rotatably connected to the base 10 and has an engageable position and a non-engageable position. Specifically, a clamping portion 812 is provided at the left end of the starting linkage rod 81 for receiving the second end (i.e., the lower end) of the limit linkage rod 68. The starting linkage rod 81 is connected to the base 10 through a connecting member 811 and can rotate around the connecting member 811. The lower end of the starting rod 74 of the manual starting device is connected to the right part of the starting linkage rod 81 so that when the user presses the pressing member 73, the upward movement of the starting rod 74 can drive the starting linkage rod 81 to rotate counterclockwise around the connecting member 811 to move from the engageable position to the non-engageable position. The lower end of the output rod 72 of the electric starting device is connected to the right part of the starting linkage rod 81 so that when the motor is started, the upward movement of the output rod 72 can drive the starting linkage rod 81 to rotate counterclockwise around the connecting member 811. Thus, whether it is the electric starting device or the manual starting device, it can drive the starting linkage rod 81 to rotate counterclockwise around the connecting member 811 to move from the non-engageable position to the engageable position.

[0058] Next, referring to Figure 4 andFigure 6 Describe the specific structure and application process of the rope control device:

[0059] When the indoor environment of building 1 is in a normal state (i.e., non-fire state), the movable window 3 is in the closed position. At this time, the starting rod 74 is at the initial position of the starting rod, the output rod 72 is at the initial position of the output rod, the starting linkage rod 81 is at the engageable position, and the limiting device 60 is at the first position. Since the engaging portion 812 of the limiting linkage rod 68 abuts against the second end (i.e., the lower end) of the starting linkage rod 81, each component can be held in place. The free end of the limiting member 63 in the limiting device 60 abuts against the external gear ring 42, so that the storage wheel 40 can only rotate in the clockwise direction, and the storage wheel 40 rotating in the clockwise direction can only tighten the rope 5. In other words, the storage wheel 40 rotating in the clockwise direction can only wind the rope 5 tighter. Thus, when the indoor environment of building 1 is in a normal state, the movable window 3 can be held in the closed position.

[0060] When the indoor environment temperature of building 1 rises (i.e., fire state), the control device (not shown) can send a signal to the motor to control the motor to start. When the motor starts, the output rod 72 can move from the initial position of the output rod to the predetermined position of the output rod, so that the starting linkage rod 81 rotates counterclockwise around the connecting member 811 from the engageable position to the non-engageable position. The engaging portion 812 of the starting linkage rod 81 no longer abuts against the second end (i.e., the lower end) of the limiting linkage rod 68. The limiting linkage rod 68 drives the limiting device 60 to rotate counterclockwise around the first rotating shaft 621 from the first position to the second position under the action of the second elastic member 69. The free end of the limiting member 63 no longer abuts against the external gear ring 42, so that the storage wheel 40 can rotate counterclockwise. The user rotates the handle 4 counterclockwise to rotate the storage wheel 40 to release the rope 5. The rope 5 no longer restricts the movable window 3, and the movable window 3 moves from the closed position to the open position. Thus, the movable window 3 is opened, and the smoke indoors can be discharged from building 1.

[0061] It should be noted that after the motor starts, the output rod 72 moves upward relative to the motor body 71 (i.e., from the initial position of the output rod to the predetermined position of the output rod) so that the starting linkage rod 81 reaches the non-engageable position and the limiting device 60 reaches the second position, and then the output rod 72 moves downward relative to the motor body 71 (i.e., from the predetermined position of the output rod to the initial position of the output rod). The output rod 72 drives the starting linkage rod 81 to rotate clockwise around the connecting member 811 back to the engageable position.

[0062] In the rope control device of the present invention, the user can also press the pressing member 73 to open the movable window 3 when the indoor environmental temperature rises (i.e., in a fire state). Specifically, when the user presses the pressing member 73, the inclined portion of the pressing member 73 applies a force to the starting rod 74, causing the starting rod 74 to move from the initial position of the starting rod to the predetermined position of the starting rod. The starting rod 74 drives the starting linkage rod 81 to rotate counterclockwise around the connecting member 811 from the engageable position to the non-engageable position. The engaging portion 812 of the starting linkage rod 81 no longer abuts against the second end (i.e., the lower end) of the limit linkage rod 68. Under the action of the second elastic member 69, the limit linkage rod 68 drives the limiting device 60 to rotate counterclockwise around the first rotating shaft 621 from the first position to the second position. The free end of the limiting member 63 no longer abuts against the external gear ring 42, enabling the storage wheel 40 to rotate counterclockwise. The user rotates the handle 4 counterclockwise to rotate the storage wheel 40 and release the rope 5. The rope 5 no longer restricts the movable window 3, and the movable window 3 moves from the closed position to the open position. Thus, the movable window 3 is opened, and the smoke indoors can be discharged from the building 1.

[0063] It should be noted that after the user presses the pressing member 73, the third elastic member 75 applies a force to the pressing member 73 to move the pressing member 73 away from the starting rod 74. The starting rod 74 is no longer pressed by the pressing member 73 and moves from the predetermined position of the starting rod to the initial position of the starting rod, and drives the starting linkage rod 81 to rotate clockwise around the connecting member 811 from the non-engageable position to the engageable position.

[0064] It can be understood that regardless of whether the movable window 3 is opened by the electric starting device or the manual starting device, the starting linkage rod 81 has returned to the engageable position at this time. However, since the limiting device 60 is still in the second position, the storage wheel 40 can rotate both clockwise and counterclockwise at this time.

[0065] When the indoor environment of the building 1 returns to the normal state (i.e., non-fire state), the user can rotate the handle 4 clockwise to rotate the storage wheel 40 clockwise, thereby tightening the rope 5. As the rope 5 is tightened, the movable window 3 moves from the open position to the closed position. After the movable window 3 reaches the closed position, the user pulls up the reset rod 67 to move the limiting device 60 around the first rotating shaft 621 from the second position to the first position. When the limiting device 60 moves to the first position, the limit linkage rod 68 re-engages the starting linkage rod 81 located at the engageable position. The limit linkage rod 68 is abutted by the engaging portion 812 of the starting linkage rod 81 and thus remains in the first position.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
