Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
As shown in fig. 1, the invention provides a breathable fire-resistant groove box, which comprises a main body 1 installed on a wall and a cover plate 2 fixedly embedded on the main body 1 through a clamping groove 3, wherein the upper surface of the cover plate 2 along the gravity direction is provided with an exhaust hole 4 penetrating through the outside, a baffle plate 5 capable of falling under the action of gravity to cover the exhaust hole 4 is arranged in the cover plate 2, and one side of the exhaust hole 4 supports one side of the baffle plate 5 through a hot melting stay 6 melting when being heated.
The core point of the invention is that the baffle 5 is obliquely supported above the vent hole 4 through the hot melting supporting strip 5, and the outside air enters the main body 1 through the vent hole 4 without barrier by lifting one side of the baffle 5; when a fire disaster occurs outside the main body 1 and the cover plate 2, the hot-melting supporting strips 6 are heated and melted, the baffle 5 which is not supported by the hot-melting supporting strips 6 falls under the action of gravity, and the exhaust holes 4 are sealed; and when the cable in the main body 1 and the cover plate 2 is on fire, the fire can be prevented from spreading outwards by covering the exhaust holes 4 with the baffle plates 5.
It should be noted that, in real life, there are many possible installation directions of the main body 1 and the cover 2, so the baffle 5 is disposed on the upper surface of the cover 1 in the gravity direction in this embodiment, so that the present device is not affected by the installation direction of the main body 1.
The hot-melt stay 6 is a strip structure made of an EVA hot-melt adhesive material.
The EVA hot melt adhesive is a polymer which does not need solvent, contains no water and is meltable in 100% solid, is solid at normal temperature, is heated and melted to a certain degree to become a liquid adhesive which can flow and has certain viscosity, and is light brown translucent or natural white after being melted. Generally speaking, the melting point of the EVA hot melt adhesive is about 80 ℃, and the temperature of flame is far higher than the melting point.
Because the hot melting stay 6 is a colloidal substance after being melted, and part of the colloidal substance can be attached between the contact surfaces of the cover plate 2 and the baffle plate 5, the effect of adhesion and sealing is achieved.
The other side of the baffle 5 is hinged to the surface of the cover plate 2, and a balancing weight 7 is arranged on the baffle 5 corresponding to the hot-melting stay 6.
The gravity that makes the left end of baffle 5 receive through balancing weight 7 increases for the speed that baffle 5 dropped is accelerated, and opposite side through baffle 5 is articulated with 2 surfaces of apron, makes the orbit of baffle 5 remain stable, makes baffle 5 difficult emergence squints after dropping.
As shown in fig. 2 and 3, a locking groove 8 is formed in the upper surface of the cover plate 2, an abutting plate 9 which can be sleeved in the locking groove 8 when the baffle 5 falls is arranged on the baffle 5, and a sliding lock block 10 for fixing the abutting plate 9 is transversely slidably mounted on the side wall of the locking groove 8.
A clamping groove 11 is formed in the butt joint plate 9 corresponding to the sliding locking block 10.
The butt joint plate 9 that drops through baffle 5 and make nests in locking recess 8, and locking recess 8 is inside to be nested in the joint groove 11 that butt joint plate 9 applied for high through slip locking piece 10 for butt joint plate 9 locking is in locking recess 8.
The side wall of the locking groove 8 is provided with a movable cavity 12, the sliding lock block 10 is slidably nested in the movable cavity 12, an extrusion air bag 13 is arranged between the side wall of the movable cavity 12 and the sliding lock block 10, and the bottom end of the extrusion air bag 13 extends into the locking groove 8.
The principle of pushing the sliding lock block 10 is as follows: nested in locking recess 8 through butt plate 9, under the effect of gravity, butt plate 9 bottom oppression extrusion gasbag 13's right-hand member for the left end inflation grow of extrusion gasbag 13, be located activity chamber 12 through extrusion gasbag 13 left end extrusion right-hand member slip locking piece 10, thereby slip locking piece 10 moves to the right side, until nested in joint groove 11.
Through the mutual locking of butt plate 9 and locking groove 8 for baffle 5 is to the sealed stability reinforcing of exhaust hole 4, places when the condition of a fire takes place, rocks the condition that makes baffle 5 drop to the cable tray and takes place, thereby makes the condition of a fire still to have the possibility of stretching, improves the stability and the security of device.
Wherein, the baffle 5 is provided with a curved rubber 14 for plugging the exhaust vent 4.
The curved rubber 14 is nested in the exhaust hole 4, so that the sealing performance of the baffle 5 to the exhaust hole 4 is enhanced.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
