[0046] Embodiment 1:
[0047] Please refer to Figure 1 The embodiment provides a non-contact orderer 100, which is installed on the door along of a pair of fireproof doors 200, and provides the function of automatically assisting the order closing of the pair of fireproof doors 200. Specifically, it comprises a fixed frame 1, a rotating shaft 2 and an order piece 3. As shown in the figure, Figure 2 The fixed frame 1 comprises a fixed plate 11 and two shaft supporting plates 12 arranged on one side of the fixed plate 11, and the fixed plate 11 and the two shaft supporting plates 12 form an installation area 13.
[0048] The two ends of the rotating shaft 2 are arranged on the two shaft supporting plates 12, specifically, the two shaft supporting plates 12 have coaxial through holes, and after the rotating shaft 2 passes through the through holes of the two shaft supporting plates 12, the two ends are limited. In this embodiment, the rotating shaft 2 is limited by nut locking and shaft end abutting on the outer side of the two shaft supporting plates 12, so that the rotating shaft 2 is fixed on the two shaft supporting plates 12 and does not fall off. In other embodiments, the limiting mode of the two ends of the rotating shaft 2 can also be welding, riveting and the like. The rotating shaft 2 has an optical axis segment 21 in the installation area 13.
[0049] The sequence device 3 is arranged in the mounting area 13, including a sleeve 31 arranged outside the optical axis segment 21 and a pressing rod 32 and an inspiration rod 33 arranged on the sleeve 31. The pressing rod 32 is formed by extending from the middle of the sleeve 31 to the direction away from the fixed frame 1, and the inspiration rod 33 is formed by extending from the side of the sleeve 31 away from the end of the pressing rod 32 to the direction away from the fixed frame 1. In this embodiment, the sleeve 31 is a tubular structure and is sleeved on the optical axis segment 21 and can rotate around the axis core of the optical axis segment 21. The pressing rod 32 and the inspiration rod 33 can rotate with the sleeve 31 to realize linkage.
[0050] Please Figures 1-2 on the basis of Figure 3 , the end of the pressing rod 32 is provided with an execution assembly 321, and the inside of the execution assembly 321 is provided with a first magnet 3211. The door opposite to the execution assembly 321 of the fireproof door 200 has a second magnet 201 opposite to the position of the first magnet 3211, and the first magnet 3211 and the second magnet 201 are arranged opposite to each other with the same polarity. And a first inspiration magnet 331 is fixedly arranged at the end of the inspiration rod 33, and a second inspiration magnet 202 opposite to the first inspiration magnet 331 is arranged at the top of the door opposite to the inspiration rod 33 of the fireproof door 200, and the first inspiration magnet 331 and the second inspiration magnet 202 are arranged opposite to each other with the same polarity.
[0051] In order to facilitate the subsequent description, we call the fireproof door opposite to the execution assembly 321 as the rear fireproof door 204, and the fireproof door acted by the inspiration rod 33 as the front fireproof door 203. Continue to refer to Figures 1-3 , after the front fireproof door 203 and the rear fireproof door 204 are opened in turn, the non-contact sequence device 100 is started. Due to the separation of the first inspiration magnet 331 and the second inspiration magnet 202, the sequence device 3 is rotated downward under the action of the gravity of the pressing rod 32, and the end of the inspiration rod 33 is tilted and falls. In order to control the angle of the sequence device 3 falling, a limiting structure can be arranged on the side of the sleeve 31 close to the fixed plate 11, so that the sleeve 31 stops rotating at a specified angle, and the inspiration rod 33 and the pressing rod 32 are in a static waiting state. At this time, the first magnet 3211 is inclined downward and points to the direction of the rear fireproof door 204, and the first inspiration magnet 331 falls to the position close to the bottom of the door frame of the front fireproof door 203.
[0052] The front fire door 203 and the rear fire door 204 return to the closed position under the drive of the closer, if the rear fire door 204 returns first than the front fire door 203, the second magnet 201 arranged on the rear fire door 204 is affected by the magnetic force and the repulsive force of the same pole when close to the first magnet 3211, the rear fire door 204 is “pressed” by the first magnet 3211 and cannot continue to reset. In the case of no contact, the rear fire door 204 can be blocked to avoid the mechanical fatigue deformation and wear of the door surface of the rear fire door 204 due to the long-term collision and pressure of the closer, thereby improving the service life of the fire door 200. In addition, since the first magnet 3211 and the second magnet 201 have larger force receiving area and better buffering effect than the existing sequence closer, the design service life will be longer and more stable.
[0053] In addition, since the acting force is the magnetic field force, even if the stress angle of the pressure rod 32 and the rear fire door 204 is large, the non-contact sequence closer 100 can “press” the rear fire door 204 with less impact on the service life, and reduce the problem of fatigue fracture of the connection between the pressure rod 32 and the sleeve 31 caused by the large stress angle.
[0054] When the front fire door 203 returns to the closed state, the second inspiration magnet 202 arranged on the top of the front fire door 203 is close to the first inspiration magnet 331, and is affected by the magnetic force and the repulsive force of the same pole, so that the first inspiration magnet 331 is forced to move upward, thereby driving the inspiration rod 33, rotating the sequence part 3 as a whole, and the pressure rod 32 also moves upward. The magnetic field direction of the first magnet 3211 and the second magnet 201 is close to vertical to the upward direction of the end of the pressure rod 32, so that the pressure rod 32 can move the first magnet 3211 away from the magnetic field range of the second magnet 201 without overcoming or only overcoming a small magnetic field force. The rear fire door 204 is driven by the closer to continue to reset until it is closed. In the design process, since the repulsive force of the first inspiration magnet 331 and the second inspiration magnet 202 only needs to overcome the overall weight of the sequence part 3 and a small amount of rotational friction, as well as a small amount of magnetic field component force of the first magnet 3211 and the second magnet 201. Therefore, the overall volume of the non-contact sequence closer 100 is small, the action is light and flexible, and the problem of jamming is not easy to occur, and the non-contact thrust also prevents the top of the front fire door 203 from appearing mechanical fatigue deformation.
[0055] In some embodiments, graphite bearings 34 are arranged between the sleeve 31 and the rotating shaft 2 near the positions of the pressure rod 32 and the inspiration rod 33. Figure 4As shown, in practical applications, graphite bearing 34 is more suitable for improving structural compactness and stability. The placement of the top pressure rod 32 and the initiating rod 33 ensures that, during long-term use, the sleeve 31 and the rotating shaft 2 will not be in a "suspended" state, preventing localized bending deformation of the sleeve 31 under long-term stress, thus improving the service life of the non-contact sequentialer 100. Of course, in other less demanding applications, using standard roller bearings or sliding bearings can also reduce the rotational friction between the rotating shaft 2 and the sleeve 31.
[0056] Please see Figure 5 On any plane perpendicular to the rotation axis 2, the angle between the projection of the core of the pressing rod 32 and the initiating rod 33 is between 11° and 18°. This angle limitation ensures the non-contact locator 100 can function normally while effectively reducing the rotational friction force that the locating element 3 needs to overcome and the magnetic field components of the first magnet 3211 and the second magnet 201. This improves the flexibility of the non-contact locator 100.
[0057] In some embodiments, the actuation component 321 includes a base 3212 and a buffer 3213. The base 3212 is fixedly connected to the end of the pressing rod 32. A first magnet 3211 is disposed on the inner side of the base 3212 away from the pressing rod 32, and the buffer 3213 is disposed on the side of the base 3212 away from the pressing rod 32. Figures 1-5 Based on the above Figure 6 The first magnet 3211 is positioned inside the base 3212 to better protect it from external environmental factors such as corrosion in humid environments, and also to protect it from abnormal impacts. The buffer 3213 is included to account for the possibility of the door closer's damping structure failing when the fire door 200 is pulled to reset, causing the rear fire door 204 to accelerate excessively and collide with the actuator 321. The buffer 3213 can absorb energy and deform under such circumstances, preventing damage caused by hard contact between the actuator 321 and the rear fire door 204. In this embodiment, the buffer 3213 is a compressible sponge block.
[0058] Furthermore, the base 3212 is adsorbed and connected to the first magnet 3211. The base 3212 can be made of a metal material that can be attracted by a magnet. When the first magnet 3211 is placed inside the base 3212, there is no need to provide a locking structure for the first magnet 3211 or use additional accessories to firmly fix the first magnet 3211 to the base 3212. After the first magnet 3211 is adsorbed onto the base 3212, the actual magnetic field range will increase because the material of the base 3212 is magnetized after adsorption. The force-bearing surface of the first magnet 3211 and the second magnet 201 is increased, thereby improving the service life of the non-contact locator 100 and the rear fire door 204.
[0059] In summary, the non-contact orderer provided by the embodiment can assist the open fireproof door to work in sequence by the first magnet and the second magnet, and the first heuristic magnet and the second heuristic magnet. The orderer does not directly contact the two fireproof doors, which avoids mechanical fatigue deformation and wear of the fireproof door due to long-term collision and pressure of the orderer, and improves the service life of the fireproof door.
[0060] Secondly, since the first magnet and the second magnet have larger force receiving area and better buffering effect, their design service life will be longer and more stable. Even if the force angle of the pressure rod and the rear fireproof door is large, the rear fireproof door can be “pressed” with less impact on the service life, reducing the problem of fatigue fracture at the connection between the pressure rod and the sleeve.
[0061] In addition, since the non-contact orderer provided by the embodiment is driven by magnetic field force, the force receiving area is increased, and compared with the contact mode of the existing orderer, the overall volume is smaller under the same bearing capacity, the action is more flexible and light, and the problem of jamming is less likely to occur.
[0062] Embodiment 2:
[0063] On the basis of Figures 1-6 , please refer to Figure 7 , the embodiment is optimized on the basis of the non-contact orderer 100 described in embodiment 1. The difference is that the heuristic rod 33 further includes an emergency heuristic wheel 332, and the emergency heuristic wheel 332 is rotationally arranged at the end of the heuristic rod 33 and located away from the first heuristic magnet 331. Similarly, the execution assembly 321 further includes an emergency pressure wheel 3214, and the emergency pressure wheel 3214 is rotationally arranged at the side of the base 3212 away from the heuristic rod 33.
[0064] The purpose of setting the emergency inspiration wheel 332 and the emergency top pressing wheel 3214 is that the non-contact sequencer 100 can still achieve the effect of the sequential closing of the fire door 200 when the two pairs of magnets fail. Especially for the fire door 200 near the fire source, considering that the magnets may fail due to demagnetization under high temperature. After the first inspiration magnet 331 and the second inspiration magnet 202 fail, the front fire door 203 is reset, the sequencer 3 cannot rotate, and the rear fire door 204 cannot continue to reset. When the first magnet 3211 and the second magnet 201 fail, the rear fire door 204 will be in contact with the buffer 3213, the rotation resistance of the sequencer 3 will increase, and the rear fire door 204 will also fail to continue to reset. When the emergency inspiration wheel 332 and the emergency top pressing wheel 3214 are set, the front fire door 203 contacts and opens the emergency inspiration wheel 332, so that the sequencer 3 rotates, and the emergency top pressing wheel 3214 can reduce the friction force of the contact with the rear fire door 204, so that the rear fire door 204 can continue to reset smoothly.
[0065] It should be noted that when the non-contact sequencer 100 is working normally, the emergency inspiration wheel 332 will be driven away from the front fire door 203 due to the action of the first inspiration magnet 331 and the second inspiration magnet 202, so as to avoid contact between the two. Similarly, due to the action of the first magnet 3211 and the second magnet 201, the emergency top pressing wheel 3214 will not be in direct contact with the rear fire door 204, so the addition of the emergency inspiration wheel 332 and the emergency top pressing wheel 3214 will not cause mechanical fatigue damage of the fire door 200.
[0066] The setting of the emergency inspiration wheel 332 and the emergency top pressing wheel 3214 can effectively ensure that the fire door 200 cannot be closed in the case that the magnets fail and the non-contact sequencer 100 cannot work normally.
[0067] Embodiment 3:
[0068] This embodiment is based on embodiment 2 and provides a non-contact sequencer 100, which is based on Figures 1-7 and please refer to Figures 8-9 The difference between this embodiment and embodiment 2 is that the housing 4 wrapping the installation area 13 is further included, and the emergency inspiration wheel 332 is arranged in the emergency through hole 41 in the corresponding position of the housing 4 in the working state. The setting of the housing 4 can effectively reduce the influence of oil stains, dust and the like in the environment on the entire non-contact sequencer 100, and prolong the service life of the non-contact sequencer 100. The setting of the emergency through hole 41 can effectively limit the position of the falling of the emergency inspiration wheel 332, so that the emergency inspiration wheel 332 can be smoothly lifted in the emergency state.
[0069] As Figure 9As shown, in some embodiments, the emergency through hole 41 is provided with a sequence termination piece 42 on the inside of the shell 4 in the direction of the inspiration rod 33, which can be moved and cover the emergency through hole 41. When the fire door 200 or the non-contact sequence device 100 is being overhauled, the sequence termination piece 42 can block the emergency through hole 41, realize the sequence function of closing the sequence device, so as to troubleshoot the problems of the fire door 200 and the sequence device. Of course, in other embodiments, components can also be added between the top pressure rod 32 and the shell 4 so that the top pressure rod 32 does not fall and "stops" the fire door 204.
[0070] The above is only an example and description of the structure of the present application, which is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these obvious alternative forms are within the scope of the present application.
