Abstract

This invention relates to the field of mechanical connection technology and discloses a quick-release device for a special protective cylinder and its usage method. The device includes a cylinder body with a cylinder cover connected to one end. A quick-release mechanism is horizontally installed on the outer surfaces of the cylinder body and the cylinder cover. The quick-release mechanism is used to quickly open the cylinder cover on the cylinder body. In this invention, the traction force required to disconnect the traction mechanism is greater than the force required for the pin to disengage from the quick-release mechanism. Therefore, when the traction mechanism disconnects, the pin also disengages from the quick-release mechanism. After disconnection, the power mechanism continues to rotate, retracting the disconnected traction rod into the driver's cab, allowing the driver to observe the disconnected traction rod and thus determine whether the cylinder cover is open.

Description

Technical Field

[0001] This invention relates to the field of mechanical connection technology, and in particular to a quick-release device for a special protective cylinder and its usage method. Background Technology

[0002] In the fields of chemical engineering, energy, aerospace testing, and special equipment, there are many large containers that require rapid opening and closing.

[0003] Traditional connection methods primarily involve circumferential multi-bolt fastening. The disadvantages of this method are: locking and unlocking require individual operations, which is extremely time-consuming and labor-intensive, making it unsuitable for emergency, rapid opening situations. Existing quick-release methods, such as cam-type or hinge-type, often suffer from insufficient locking force and unclear separation paths, leading to poor sealing and other problems.

[0004] This invention provides a component device that can provide a large locking force, ensure a tight seal, and unlock instantly upon receiving a command, allowing the hatch to separate smoothly.

[0005] Therefore, the above problems are solved by a quick-release device for a special protective cylinder and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a quick-release device for special protective cylinders and its usage method, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cylindrical body is included, one end of which is connected to a cap, and a quick-release mechanism is horizontally installed on the outer surface of the cylindrical body and the cap, the quick-release mechanism being used to quickly open the cap on the cylindrical body.

[0008] Preferably, the power mechanism is used to drive the disassembly of the quick-release mechanism to open the cylinder cover on the cylinder body.

[0009] Preferably, the power mechanism and the quick-unloading mechanism are connected by a traction rope, a traction mechanism is installed between the traction ropes, one end of the quick-unloading mechanism is connected to one end of the traction mechanism by the traction rope, a limit stud is installed between the quick-unloading mechanism and the traction mechanism, and the other end of the traction mechanism is connected to the power mechanism by the traction rope.

[0010] Preferably, the quick-release mechanism includes an upper locking body and a lower locking body, the upper locking body being installed on the outer circular surface of the cylinder cover, and the lower locking body being installed on the outer circular surface of the cylinder body.

[0011] Preferably, the upper locking body has a first spherical annular groove inside, and the upper locking body has a through hole on its end face, with the first spherical annular groove located inside the upper locking body.

[0012] Preferably, the interior of the lower lock body is stepped.

[0013] Preferably, the upper and lower locking bodies are internally equipped with pins, and the upper and lower locking bodies are connected by the pins to connect the cylinder body to the cylinder cover.

[0014] Preferably, the pin includes a sleeve rod, the outer circular surface of which is fitted with a first spring. The sleeve rod is located between the upper and lower locking bodies. The first spring of the sleeve rod is in contact with the stepped platform inside the upper locking body. The sleeve rod has a hole and an installation chamber inside.

[0015] Preferably, a core rod is slidably connected inside the sleeve rod, and a traction head is interference-fitted to one end of the core rod. A movable shaft is slidably connected inside the traction head, and the movable shaft is used to connect the traction head and the sleeve rod.

[0016] Preferably, a second spring is installed at one end of the traction head near the core rod, a sliding plate is engaged with the outer circular surface of the core rod, the part of the traction head with the second spring is located inside the mounting chamber, and the sliding plate is in contact with the bottom end of the mounting chamber.

[0017] Preferably, the outer surface of the core rod is provided with steel balls, and there are multiple steel balls distributed in a circle around the core rod. The outer surface of the end of the core rod away from the traction head is provided with a groove, and there are two grooves. The steel balls are located between the two grooves and are engaged with the holes of the sleeve rod.

[0018] Preferably, the traction mechanism includes a housing, a bushing is sleeved inside the housing, and a traction rod is slidably connected inside the bushing.

[0019] Preferably, the outer circular surface of the bushing has a mounting hole in a circumferential shape, and a third spring is provided inside the mounting hole. The other end of the third spring is provided with a limiting post, which extends through the side wall of the bushing and into the interior of the bushing.

[0020] Preferably, a limiting groove is provided at the end of the traction rod near the bushing, and the limiting groove is engaged with a limiting post. The end of the traction rod away from the bushing is connected to the power mechanism through a traction rope.

[0021] A method for using a quick-release device for a special protective cylinder includes the following steps: First, a core rod is installed inside a sleeve rod, with a steel ball located between two grooves and engaging with the hole in the sleeve rod, while simultaneously defining the position of the core rod. A traction head is installed on the sleeve rod via a movable shaft. During installation, a sliding plate is installed in the middle of the core rod, located inside the installation chamber, with the end face inside the installation chamber contacting the sliding plate for compression of the second spring.

[0022] Preferably, at this time, the second spring is in a compressed state and the steel ball is located between the two grooves. Then, the pin is inserted into the interior of the lower lock body and the upper lock body as a whole, and the traction head is pushed to move into the interior of the lower lock body and the upper lock body. When the first spring on the outer circle of the sleeve contactes the stepped platform inside the upper lock body, the first spring is compressed.

[0023] Preferably, when the first spring cannot be compressed further, the traction head is pushed to slide. During the sliding process, the second spring is compressed. At this time, the movable shaft remains stationary, and the traction head drives the core rod to move. During the movement, the steel ball slides into the groove near the traction head. At this time, the traction head is pushed further. When the traction head compresses the second spring to its limit, the traction head no longer applies thrust, the second spring rebounds, and pushes the traction head to move. The traction head drives the core rod to move. During the movement, the groove sidewall of the core rod squeezes out the steel ball, so that the steel ball is located on the outer circumference of the core rod. At the same time, the steel ball passes through the hole of the sleeve rod and engages with the first spherical annular groove, thus completing the connection of the upper and lower lock bodies by the pin.

[0024] Preferably, when the pin needs to disengage, the power mechanism moves, driving the traction rope to pull the traction head to move. The movable shaft engages with the sleeve rod, compressing the second spring. The traction head drives the core rod to move, causing the steel ball to slide into the groove away from the traction head. The steel ball is no longer engaged with the first spherical annular groove. The traction head drives the pin to disengage from the upper and lower locking bodies. When the pin moves to the limit stud, the limit stud limits the pin's movement position. The power mechanism continues to move, causing the traction mechanism to separate and the traction rod to disengage from the bushing, ensuring the separation of the upper and lower locking bodies and ensuring that the cylinder cover can be opened, thus completing the opening action.

[0025] The technical effects and advantages of this invention are as follows: 1. In this invention, the traction force when the traction mechanism is disconnected is greater than the force that causes the pin to disengage from the quick-unloading mechanism. Therefore, when the traction mechanism is disconnected, the pin also disengages from the quick-unloading mechanism. After disconnection, the power mechanism continues to rotate, retracting the disconnected traction rod into the cab, making it easy for the driver to observe the disconnected traction rod and thus determine whether the cover is open.

[0026] 2. The quick-unloading mechanism of the present invention is driven by a power mechanism. The rotation of the power mechanism drives the pin inside the quick-unloading mechanism to move. The pin moves inside the quick-unloading mechanism to realize the opening and locking of the cylinder and the cylinder cover. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] In the fields of chemical engineering, energy, aerospace testing, and special equipment, there are many large containers that require rapid opening and closing.

[0041] Traditional connection methods primarily involve circumferential multi-bolt fastening. The disadvantages of this method are: locking and unlocking require individual operations, which is extremely time-consuming and labor-intensive, making it unsuitable for emergency, rapid opening situations. Existing quick-release methods, such as cam-type or hinge-type, often suffer from insufficient locking force and unclear separation paths, leading to poor sealing and other problems.

[0042] This invention provides a component device that can provide a large locking force, ensure a tight seal, and unlock instantly upon receiving a command, allowing the hatch to separate smoothly.

[0043] This invention provides, for example Figures 1 to 11 The invention relates to a quick-release device for a special protective cylinder and its usage method, comprising a cylinder body 1, a cylinder cover 2 connected to one end of the cylinder body 1, and a quick-release mechanism 4 horizontally installed on the outer surface of the cylinder body 1 and the cylinder cover 2, the quick-release mechanism 4 being used to quickly open the cylinder cover 2 on the cylinder body 1.

[0044] The cylinder body 1 and the cylinder cover 2 are hinged on one side. The hinged relationship is existing technology and will not be described in detail here. The cylinder cover 2 is used to close the cylinder body 1. The cylinder body 1 and the side wall of the cylinder cover 2 are connected to the quick-release mechanism 4, which is used to open the cylinder cover 2.

[0045] The quick-unloading mechanism 4 is driven by the power mechanism 3. The rotation of the power mechanism 3 causes the pin 7 inside the quick-unloading mechanism 4 to move. The pin 7 moves inside the quick-unloading mechanism 4 to open and lock the cylinder 1 and the cylinder cover 2.

[0046] The power mechanism 3, which is a motor, drives the take-up and release reel 8 to move the pin 7 inside the quick-release mechanism 4. The motor drives the take-up and release reel, and the take-up and release reel winds the take-up and release reel. When the motor rotates forward, the take-up and release reel winds the take-up and release reel, which drives the pin 7 to move to the outside of the quick-release mechanism 4 for opening the cylinder cover 2. When the motor rotates in reverse, the take-up and release reel releases the rope, which causes the pin 7 to move into the quick-release mechanism 4 for locking the cylinder cover 2.

[0047] The connection between the motor and the receiving disc, as well as the principle of motion, are existing technologies and will not be elaborated upon here.

[0048] Furthermore, the power mechanism 3 and the quick unloading mechanism 4 are connected by a traction rope 8, and a traction mechanism 6 is installed between the traction ropes 8. One end of the quick unloading mechanism 4 is connected to one end of the traction mechanism 6 through the traction rope 8. A limit stud 5 is installed between the quick unloading mechanism 4 and the traction mechanism 6, and the other end of the traction mechanism 6 is connected to the power mechanism 3 through the traction rope 8.

[0049] When the power mechanism 3 drives the traction rope 8 to move, the traction rope 8 drives the pin 7 to move. A traction mechanism 6 is installed between the traction rope 8 and the pin 7. The traction mechanism 6 is used to disconnect the connection between the traction rope 8 and the pin 7 to prevent the traction rope 8 from getting tangled in the cylinder 1 or the cylinder cover 2, which would prevent the cylinder cover 2 from opening. At the same time, it is used to check whether the cylinder cover 2 is open. Since the traction force of the traction mechanism 6 is greater than the force of the pin 7 disengaging from the quick-release mechanism 4, when the traction mechanism 6 is disconnected, the pin 7 also disengages from the quick-release mechanism 4. After disconnection, the power mechanism 3 continues to rotate, retracting the disconnected traction rod 606 into the cab, so that the driver can observe the disconnected traction rod 606 and thus determine whether the cylinder cover 2 is open.

[0050] When the pin 7 moves inside the quick-release mechanism 4, the limiting stud 5 is used to prevent the pin 7 from moving excessively, so as to prevent the pin 7 from completely disengaging from the quick-release mechanism 4 and causing the pin 7 to be lost. That is, after the cylinder cover 2 is opened, the pin 7 does not completely disengage from the quick-release mechanism 4. At the same time, it is also convenient for the pin 7 to enter the quick-release mechanism 4 next time, locking the cylinder 1 and the cylinder cover 2.

[0051] At the same time, the traction rope 8 passes through the top of the limiting stud 5 and connects to the pin 7. The position of the limiting stud 5 is between the traction mechanism 6 and the pin 7. The traction rope 8 passes through the limiting stud 5 to connect the traction mechanism 6 and the pin 7.

[0052] Furthermore, the quick-release mechanism 4 includes an upper locking body 401 and a lower locking body 403. The upper locking body 401 is installed on the outer circular surface of the cylinder cover 2, and the lower locking body 403 is installed on the outer circular surface of the cylinder 1. The upper locking body 401 has a first spherical annular groove 402 inside, and the upper locking body 401 has a through hole on its end face. The first spherical annular groove 402 is located inside the upper locking body 401. The interior of the lower locking body 403 is stepped; The upper locking body 401 and the lower locking body 403 are equipped with pins 7, which are connected by the pins 7 to connect the cylinder 1 and the cylinder cover 2.

[0053] The quick-release mechanism 4 includes an upper locking body 401 and a lower locking body 403. The upper locking body 401, the lower locking body 403 and the limiting stud 5 are coaxial. In this way, when the pin 7 moves inside the upper locking body 401 and the lower locking body 403, the limiting stud 5 acts as a stop for the pin 7.

[0054] The upper locking body 401 is installed on the outer circular surface of the cylinder cover 2, and the lower locking body 403 is installed on the cylinder body 1. The upper locking body 401 and the lower locking body 403 are located on the same axis. After being inserted into the upper locking body 401 and the lower locking body 403 by the pin 7, the cylinder cover 2 and the cylinder body 1 are locked.

[0055] The locking body 401 has a first spherical annular groove 402 inside, which is used to engage the steel ball 704.

[0056] The interior of the lower locking body 403 is stepped, and the stepped surface is used to compress the first spring 706. That is, one end of the first spring 706 contacts the stepped surface, and the sleeve rod 705 moves into the interior of the lower locking body 403. One end of the sleeve rod 705 presses against the first spring 706. As the sleeve rod 705 continues to extend into the interior of the lower locking body 403, the stepped end face will compress the first spring 706, so that the sleeve rod 705 can extend further into the interior of the lower locking body 403 for the steel ball 704 to engage with the first spherical annular groove 402.

[0057] Furthermore, the pin 7 includes a sleeve 705, on the outer circular surface of which a first spring 706 is sleeved. The sleeve 705 is located between the upper locking body 401 and the lower locking body 403. The first spring 706 of the sleeve 705 is in contact with the stepped platform inside the upper locking body 401. The sleeve 705 has a hole, and the sleeve 705 has an installation chamber 7010 inside.

[0058] The sleeve rod 705 is internally slidably connected to a core rod 703. One end of the core rod 703 is interference-fitted to a traction head 701. The traction head 701 is internally slidably connected to a movable shaft 702, which is used to connect the traction head 701 to the sleeve rod 705.

[0059] A second spring 708 is installed at one end of the traction head 701 near the core rod 703. A sliding plate 707 is engaged with the outer circular surface of the core rod 703. The part of the traction head 701 with the second spring 708 is located inside the mounting chamber 7010. The sliding plate 707 is in contact with the bottom end of the mounting chamber 7010.

[0060] The outer surface of the core rod 703 is provided with steel balls 704. There are multiple steel balls 704, which are distributed in a circle around the core rod 703. The outer surface of the end of the core rod 703 away from the traction head 701 is provided with a groove 709. There are two grooves 709. The steel balls 704 are located between the two grooves 709 and are engaged with the holes of the sleeve rod 705.

[0061] The core rod 703 is installed inside the sleeve rod 705. The traction head 701 is installed inside the installation chamber 7010 via the movable shaft 702. The steel ball 704 is located between two grooves 709. The two sides of the grooves 709 are conical, which facilitates the sliding of the steel ball 704 into and out of the grooves 709. It engages with the hole in the sleeve rod 705. The hole is circular. When the steel ball 704 is inside the hole, that is, when the steel ball 704 is engaged with the sleeve rod 705, the traction head 704 engages with the sleeve rod 705. When ball 704 engages with the hole, one-third of ball 704 is located inside the hole. Because ball 704 is round, when one-third of ball 704 is inserted into the hole, the ball 704 engages with the hole through the engagement force, and the friction between ball 704 and core rod 703 limits the position of core rod 703. The traction head 701 is mounted on sleeve rod 705 via movable shaft 702. During installation, sliding plate 707 is installed in the middle of core rod 703. 3. When the core rod 703 is away from the traction head 701, its diameter is larger; when the core rod 703 is close to the traction head 701, its diameter is smaller. In other words, the diameter of the core rod 703 away from the traction head 701 is larger than its diameter close to the traction head 701. Therefore, the two diameters are different. After connection, the surface with the larger diameter of the core rod 703 forms a stepped surface. The sliding piece 707 is installed at the position with the smaller diameter of the core rod 703. It slides on the core rod 703, passing through the stepped surface, preventing the sliding piece 707 from sliding to the position with the larger diameter of the core rod 703. That is, the diameter of the hole in the core rod 703 where the sliding piece 707 is installed is smaller than the diameter of the core rod 703 away from the traction head 701. The sliding piece 707 can only slide on the outer circular surface of the core rod 703 at the position close to the traction head 701. The sliding piece 707 is located inside the mounting chamber 7010, and the inner end face of the mounting chamber 7010 contacts the sliding piece 707 for compression of the second spring 708.

[0062] At this time, when the core rod 703 is installed inside the sleeve rod 705, the installation method is that the core rod 703 is inserted into the sleeve rod 705, and the core rod 703 is interference-fitted or fixedly connected to the traction head 701. The fixed connection is made by threaded connection or welding. When the traction head 701 and the sleeve rod 705 are connected together through the movable shaft 702, the second spring 708 is in a compressed state, and the steel ball 704 is located between the two grooves 709. Then, the pin 7 is inserted into the interior of the lower lock body 403 and the upper lock body 401, pushing the traction head 701 to move into the interior of the lower lock body 403 and the upper lock body 401. When the first spring 706 on the outer circular surface of the sleeve rod 705 contacts the stepped platform inside the upper lock body 401, the first spring 706 is compressed.

[0063] When the first spring 706 is no longer compressed, the traction head 701 continues to be pushed, causing it to slide. During this sliding process, the traction head 701 and the sliding plate 707 compress the second spring 708. At this time, the movable shaft 702 remains stationary. The sliding of the movable shaft 702 inside the traction head 701 is referenced. Figure 7 The traction head 701 has a sliding groove inside, and the movable shaft 702 passes through the sliding groove and connects to the sleeve rod 705. The traction head 701 drives the core rod 703 to move. During the movement of the core rod 703, the outer surface of the core rod 703 no longer presses against the steel ball 704, and slides into the groove 709 near the traction head 701 to correspond with the steel ball 704. At this time, if the traction head 701 is continued to be pushed, when the traction head 701 compresses the second spring 708 to its limit, it also indicates that the steel ball 704 is no longer located on the core rod 705. On the outer circumference of 03, the steel ball 704 is located inside the groove 709. The traction head 701 no longer applies thrust, and the second spring 708 rebounds, pushing the traction head 701 to move. The traction head 701 drives the core rod 703 to move. During the movement, the side wall of the groove 709 of the core rod 703 squeezes out the steel ball 704, so that the steel ball 704 is located on the outer circumference of the core rod 703. At the same time, the steel ball 704 passes through the hole of the sleeve rod 705 and engages with the first spherical annular groove 402, thus completing the connection of the upper lock body 401 and the lower lock body 403 by the pin 7.

[0064] The diameter of the steel ball 704 is larger than the diameter of the hole in the sleeve rod 705 to prevent the steel ball 704 from falling out of the hole in the sleeve rod 705. At the same time, the position of the steel ball 704 and the sleeve rod 705 is always corresponding. The steel ball 704 is engaged with the first spherical annular groove 402, which compresses the core rod 703 and makes the steel ball 704 engage with the first spherical annular groove 402. When the engagement is not required, the groove 709 corresponds to the core rod 703.

[0065] When the pin 7 needs to disengage, the power mechanism 3 moves, causing the traction rope 8 to pull the traction head 701 to move. The movable shaft 702 engages with the sleeve rod 705, and the movable shaft 702 and the sliding plate 707 compress the second spring 708. The traction head 701 drives the core rod 703 to move, that is, the groove 709 of the core rod 703 slides away from the direction of the traction head 701 and aligns with the steel ball 704, so that the outer surface of the core rod 703 no longer presses against the steel ball 704, and the steel ball 704 no longer... The first spherical annular groove 402 engages, and the traction head 701 drives the pin 7 to disengage from the upper locking body 401 and the lower locking body 403. When the pin 7 moves to the limiting stud 5, the limiting stud 5 limits the movement of the pin 7. The power mechanism 3 continues to move, causing the traction mechanism 6 to separate and the traction rod 606 to disengage from the bushing 602, ensuring that the upper locking body 401 and the lower locking body 403 are separated, and ensuring that the cylinder cover 2 of the cylinder 1 can be opened, thus completing the movement opening action.

[0066] Furthermore, the traction mechanism 6 includes a housing 601, a bushing 602 is sleeved inside the housing 601, and a traction rod 606 is slidably connected inside the bushing 602.

[0067] The outer circular surface of the bushing 602 is provided with a mounting hole 603 in a circumferential shape. A third spring 604 is provided inside the mounting hole 603. A limit post 605 is provided at the other end of the third spring 604. The limit post 605 extends through the side wall of the bushing 602 and into the interior of the bushing 602.

[0068] The end of the traction rod 606 near the bushing 602 has a limiting groove 607, which is engaged with the limiting post 605. The end of the traction rod 606 away from the bushing 602 is connected to the power mechanism 3 through the traction rope 8.

[0069] The housing 601 of the traction mechanism 6 is fitted with a bushing 602. The housing 601 and the bushing 602 have through holes to facilitate the connection of the traction rope 8 to the housing 601 and the bushing 602. The outer surface of the bushing 602 has multiple mounting holes 603 that penetrate the bushing 602. The mounting holes 603 are distributed in a circle on the outer surface of the bushing 602. A third spring 604 is installed inside the mounting holes 603. The third spring 604 extends into the bushing 602 and a limiting post 605 is installed. The limiting post 605 is used to engage the traction rod 606. That is, the limiting post 605 penetrates the bushing 602 and extends into the bushing 602.

[0070] Then, the outer surface of the bushing 602 is sealed by the housing 601 to prevent the third spring 604 from coming out of the mounting hole 603, and the bushing 602 is installed inside the housing 601.

[0071] The traction rod 606 has an annular limiting groove 607 at one end near the bushing 602. The limiting groove 607 engages with the limiting post 605. That is, when the traction rod 606 is inserted into the bushing 602, the end face of the traction rod 606 is conical. The limiting post 605 slides on the conical surface of the traction rod 606 into the limiting groove 607, thus completing the engagement between the traction rod 606 and the bushing 602.

[0072] The locking end of the limiting post 605 is an arc surface, which facilitates sliding and prevents the phenomenon of being unable to slide inside the limiting groove 607.

[0073] During the sliding process of the traction rod 606, the conical surface of the traction rod 606 presses against the limiting post 605, the limiting post 605 compresses the third spring 604, and the third spring 604 moves towards the housing 601. When the limiting post 605 slides into the limiting groove 607 of the traction rod 606, the third spring 604 releases pressure and pushes the limiting post 605 to move towards the limiting groove 607, thereby realizing the engagement of the traction rod 606 with the bushing 602.

[0074] When the traction rod 606 needs to disengage from the bushing 602, the power mechanism 3 pulls the traction rope 8 to move. The traction rope 8 drives the traction rod 606 to move away from the bushing 602. At this time, the traction rod 606 moves, and the side wall of the limiting groove 607 of the traction rod 606 will squeeze the limiting post 605. At this time, the limiting post 605 compresses the third spring 604. The third spring 604 moves towards the housing 601. When the limiting post 605 slides out of the limiting groove 607, the third spring 604 releases pressure and pushes the limiting post 605 towards the traction rod 606, so that the limiting post 605 returns to its initial position. At this time, the traction rod 606 disengages from the bushing 602. After disconnection, the power mechanism 3 continues to rotate, bringing the disconnected traction rod 606 into the cab, so that the driver can observe the disconnected traction rod 606 and thus determine whether the cover 2 is open.

[0075] In addition, this device is not only used for connecting the cylinder 1 and the cylinder cover 2, but also for locking doors. This door does not need to be locked. As long as it is closed, or temporarily closed, the door can be opened quickly. Similar to fire doors, fire doors do not need to be locked. They only need to be closed normally and can be opened quickly in an emergency. The door is equipped with a lower lock body 403 and the door frame is equipped with an upper lock body 401. The pin 7 is inserted into the upper lock body 401 and the lower lock body 403 to complete the closing of a single fire door.
