DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0036] See also Figures 1 to 5 As shown, an embodiment of an electric opening and closing explosion-proof door provided by the utility model.

[0037] The electric opening and closing explosion-proof door comprises a main body component, the main body component comprises a door frame 11 and an explosion-proof door body 12, the explosion-proof door body 12 is rotatably connected to the door frame 11, and the electric opening and closing explosion-proof door further comprises an opening and closing component, the opening and closing component comprises:

[0038] A driving linkage mechanism, the driving linkage mechanism comprises a driving component 21, a first connecting rod 22 and a second connecting rod 23, the driving component 21 is relatively fixed to the door frame 11, when the driving component 21 is powered on and executes a door opening command, the power output shaft of the driving component 21 rotates forward, when the driving component 21 is powered on and executes a door closing command, the power output shaft of the driving component 21 rotates reversely, when the driving component 21 is powered off, the power output shaft of the driving component 21 is stationary, one end of the first connecting rod 22 is transmission-connected to the driving component 21, one end of the second connecting rod 23 is rotatably connected to the explosion-proof door body 12, and the other end of the first connecting rod 22 and the other end of the second connecting rod 23 are slidably and rotatably connected without being disengaged;

[0039] A latch mechanism, the latch mechanism is installed on the first link 22 or the second link 23. When the latch mechanism is powered on, the latch mechanism limits the relative sliding of the first link 22 and the second link 23 but allows the relative rotation of the first link 22 and the second link 23. The first link 22 and the second link 23 transmit power to each other. When the latch mechanism is powered off, the latch mechanism allows the first link 22 and the second link 23 to slide and rotate relative to each other. The first link 22 and the second link 23 do not transmit power to each other.

[0040] A control mechanism (not shown in the figure), the control mechanism is used to control the power on and off of the latch mechanism, the power on and off of the drive component, and send door opening and closing instructions to the drive component.

[0041] The explosion-proof door body 12 is rotatably connected to the door frame 11 around a first axis, the power output shaft of the driving component 21 rotates around a second axis, the first connecting rod 22 and the second connecting rod 23 rotate around a third axis, and the second connecting rod 23 is rotatably connected to the explosion-proof door body 12 around a fourth axis, and the first axis, the second axis, the third axis and the fourth axis are all arranged in parallel.

[0042] The above-mentioned electric opening and closing explosion-proof door has the following first working state, second working state and third working state:

[0043] When the electric opening and closing explosion-proof door is in the first working state, the driving component 21 is energized and executes the door opening command, the latch mechanism is energized, the power output shaft of the driving component 21 rotates forward, driving the first connecting rod 22 and the second connecting rod 23 to rotate, thereby driving the explosion-proof door body 12 to open;

[0044] When the electric opening and closing explosion-proof door is in the second working state, the driving component 21 is energized and executes the door closing command, the latch mechanism is energized, the power output shaft of the driving component 21 is reversed, driving the first connecting rod 22 and the second connecting rod 23 to rotate, thereby driving the explosion-proof door body 12 to close;

[0045] When the electric opening and closing explosion-proof door is in the third working state, the latch mechanism is powered off, the first connecting rod 22 and the second connecting rod 23 do not drive each other, and the explosion-proof door body 12 is opened by manpower.

[0046] By providing a latch mechanism and a driving component, the explosion-proof door can be opened electrically or manually. When the explosion-proof door is opened electrically, the latch mechanism is energized, and the explosion-proof door body is driven to open and close at a set speed by the driving component, which greatly saves manpower; when the explosion-proof door is opened manually, the latch mechanism is de-energized, and the explosion-proof door body can be opened with the help of manpower. The explosion-proof door body can be opened quickly, which solves the problem that the user cannot pass quickly due to the fixed opening speed of the existing opening and closing components.

[0047] In the preferred implementation manner of the present embodiment, one of the first connecting rod 22 and the second connecting rod 23 is a slide groove rod and the other is a rotating shaft rod, the slide groove rod is provided with a slide groove 24, the rotating shaft rod is provided with a rotating shaft 25, the slide groove 24 and the rotating shaft 25 can slide relative to each other and can rotate relative to each other without being separated from each other, the latch mechanism is an electromagnetic latch, the electromagnetic latch includes a shell 26, a lock core 27, a coil 28 and a spring 29, the shell 26 is relatively fixed to the slide groove 24, the lock core 27 is connected to the shell 26, after the coil 28 is energized, the coil 28 drives the lock core 27 to insert into the slide groove 24, and after the coil 28 is de-energized, the spring 29 drives the lock core 27 to leave the slide groove 24.

[0048] The cross section of the above-mentioned chute 24 is T-shaped, and the slot width of the chute 24 is smaller than the slot bottom width. The longitudinal section of the above-mentioned rotating shaft 25 is T-shaped, and the large end of the rotating shaft 25 is inside the chute 24 to prevent the first connecting rod 22 and the second connecting rod 23 from being separated from each other. The above-mentioned lock core 27 is equivalent to an iron core. When the coil 28 is energized, a strong magnetic force is generated to force the lock core 27, and the lock core 27 overcomes the elastic force of the spring 29 to generate the power to enter and exit the chute 24. Under normal working conditions, the power on and off of the latch mechanism and the driving component 21 are manually controlled. When an accident occurs, the latch mechanism and the driving component 21 may both be powered off. At this time, the first connecting rod 22 and the second connecting rod 23 do not drive each other. When the driving component 21 cannot rotate, the second connecting rod 23 can rotate freely. The latch mechanism is set as an electromagnetic latch, which has a simple structure and reliable operation. When an accident occurs and the latch mechanism and the driving component 21 are powered off, the explosion-proof door body 12 can also be opened and closed manually.

[0049] In the preferred implementation mode of the present embodiment, the above-mentioned rotating shaft rod is arranged on the slot side of the above-mentioned slide slot rod, and the slot wall of the above-mentioned slide slot 24 is provided with a locking through hole, and the above-mentioned lock core 27 enters and exits the above-mentioned slide slot 24 through the above-mentioned locking through hole.

[0050] The housing 26 is fixed to the outer wall of the slot of the slide slot rod. When the latch mechanism is powered on, the lock core 27 protrudes out of the slot wall of the slide slot 24, thereby blocking the shaft 25 from sliding along the slide slot 24. When the latch mechanism is powered off, the lock core 27 will not protrude out of the slot wall of the slide slot 24, and the lock core will not block the shaft 25 from sliding in the slide slot 24. The shaft rod is arranged at the notch side of the slide slot 24, and the electromagnetic latch is arranged at the side of the slide slot 24. The two do not interfere with each other, and after the electromagnetic latch is powered off, it will not affect the sliding of the shaft rod.

[0051] In the preferred implementation mode of the present embodiment, the control mechanism includes a manual door opening operation component. When the manual door opening operation component is pressed, the latch mechanism is powered off, and the drive component 21 is powered on and executes a door closing command.

[0052] The manual door opening operating component can be a mechanical button, a knob, or a touch button, etc. When the manual door opening operating component is triggered, the latch mechanism can be powered off. When the door opener wants to manually push open the explosion-proof door body, he can press the manual door opening operating component while pushing the explosion-proof door body. At this time, the lock core 27 moves out of the slide groove 24, and the second connecting rod 23 can slide relative to the first connecting rod 22 through the slide groove 24. The user can push open the explosion-proof door body 12 normally without affecting the driving component 21, thereby achieving the effect of manual door opening.

[0053] In addition, when the manual door opening operation component is triggered, the driving component 21 also starts working synchronously. Since the speed of the driving component 21 is relatively fixed under load, that is, the angular velocity of the first connecting rod 22 is relatively stable, when the user pushes the explosion-proof door body 12, the load on the driving component 21 is reduced or disappears, and the angular velocity of the second connecting rod 23 will accelerate the rotation, so that the hinge point of the first connecting rod 22 and the second connecting rod 23 returns to the original position, and when the latch returns to the inside of the slide slot 24, the second connecting rod 23 can also push the explosion-proof door body 12 to close normally. Therefore, after the user manually pushes the explosion-proof door body 12 to open, the driving component 21 can start the door closing action, and then use the second connecting rod 23 to push the first connecting rod 22 to close the explosion-proof door body 12.

[0054] When the electric opening and closing explosion-proof door is in the third working state, the latch mechanism is powered off, the driving component 21 is powered on and executes the door closing command, the first connecting rod 22 and the second connecting rod 23 do not transmit power to each other, the explosion-proof door body 12 is opened by manpower, and the driving component 21 drives the explosion-proof door body 12 to close.

[0055] By setting up a manual door opening operating component, the operation is simple and convenient, and after the explosion-proof door is pushed open by manpower, the driving component will drive the explosion-proof door to close, which greatly saves manpower.

[0056] In the preferred implementation mode of this embodiment, the above-mentioned control mechanism also includes an electric door opening operating component and an electric door closing operating component. When the above-mentioned electric door opening operating component is pressed, the above-mentioned driving component 21 is energized and executes the door opening command. When the above-mentioned electric door closing operating component is pressed, the above-mentioned driving component 21 is energized and executes the door closing command.

[0057] When the electric door opening operating component is pressed, the driving component 21 is powered on and executes the door opening command, the latch mechanism is powered on, the power output shaft of the driving component 21 rotates forward, drives the first connecting rod 22 and the second connecting rod 23 to rotate, and then drives the explosion-proof door body 12 to open. When the electric door closing operating component is pressed, the driving component 21 is powered on and executes the door closing command, the latch mechanism is powered on, the power output shaft of the driving component 21 rotates reversely, drives the first connecting rod 22 and the second connecting rod 23 to rotate, and then drives the explosion-proof door body 12 to close. The electric door opening operating component and the electric door closing operating component can be mechanical buttons, knobs or touch buttons. By setting the electric door opening operating component and the electric door closing operating component, the operation is simple and convenient.

[0058] In a preferred implementation manner of this embodiment, the above-mentioned control mechanism is a remote control device.

[0059] The remote control device is equivalent to a remote controller, which can be a remote control handle or a mobile phone, etc. The remote control opening and closing of the explosion-proof door is realized. The control mechanism is a remote control device, which is convenient for controlling the opening and closing of the explosion-proof door.

[0060] In a preferred implementation manner of the present embodiment, the explosion-proof door body 12 comprises a panel 121 and an inner door 122 , and the inner door 122 is provided with reinforcing ribs that are staggered in transverse and longitudinal directions.

[0061] The reinforcement ribs include transverse reinforcement ribs and longitudinal reinforcement ribs, the transverse reinforcement ribs extend along the door width direction, and the longitudinal reinforcement ribs extend along the door height direction. The explosion-proof door body 12 is provided with reinforcement ribs to improve the impact resistance of the explosion-proof door body 12 and make the weight of the explosion-proof door body as small as possible.

[0062] In a preferred implementation manner of this embodiment, the explosion-proof door body 12 is provided with a vent, and the vent is provided with an anti-explosion valve 13 .

[0063] The existing explosion-proof door is configured as an escape passage. Under normal conditions, the explosion-proof door is in a normally closed state and does not have a ventilation effect. Some factories that need both an escape passage and ventilation in the factory environment need to add an additional ventilation and air-permeable explosion-proof valve, and the newly added explosion-proof valve will occupy additional space on the factory wall. Ventilation and air-permeability effects are achieved by arranging vents and explosion-proof valves 13 on the explosion-proof door body 12.

[0064] In a preferred implementation manner of this embodiment, reinforcing ribs are provided around the vents.

[0065] Since the vents are relatively weak, it may affect the explosion-proof effect of the entire explosion-proof door. The reinforcement ribs of the vents are equivalent to a square frame, and the edges of the square frame are reinforcement ribs. Reinforcement ribs are arranged around the vents to ensure the impact resistance of the door body.

[0066] In a preferred implementation manner of the present embodiment, one side of the explosion-proof door body 12 is rotatably connected to the door frame 11 via a hinge 14 , and the other side of the explosion-proof door body 12 is locked to the door frame 11 via a locking member 15 .

[0067] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow the two to rotate relative to each other. The hinge can be composed of a movable component or a foldable material. The locking member 15 is, for example, a lock tongue, and the locking member 15 locks the door frame 11 and the explosion-proof door body 12 with each other, so that the explosion-proof door body 12 can remain in a closed state. The explosion-proof door body 12 is connected to the door frame 11 through the hinge 14 and the locking member 15, which facilitates the opening and closing of the explosion-proof door body 12 and ensures that the explosion-proof door body 12 cannot be opened at will after being locked.

[0068] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
