Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-4 and the embodiments.

The embodiment of the application discloses a structure of a fire cover keeps out wind. Referring to fig. 1 and 2, the wind shield cover structure includes a cover body 1, a support frame 2, and a plurality of wind shield sheets 3. The surfaces of the cover body 1, the support frame 2 and the wind-shielding sheet 3 are all provided with a layer of ceramic paint layer, the ceramic paint layer can isolate the structure surface from direct contact with flame, not only can the fire cover structure not be easy to decolor and deform due to high temperature, but also can enable the fire cover structure to have a good rust-proof function.

The support frame 2 is arranged at the periphery of the cover body 1 at intervals, and the support frame 2 comprises a positioning ring 21 and a plurality of support sheets 22. The positioning ring 21 may be polygonal or circular, which is more convenient for installing the wind-blocking sheet 3 compared to the circular positioning ring 21, and the number of polygons may be increased according to the production requirement, thereby blocking the wind of different angles. In this embodiment, the positioning ring 21 is a regular hexagon, six evenly distributed protrusions 11 are disposed on the side wall of the cover body 1, a groove suitable for the support sheet 22 to be clamped is disposed on each protrusion 11, six support sheets 22 are correspondingly disposed, and the support sheets 22 are evenly disposed at six corners of the positioning ring 21 and clamped with the six protrusions 11 on the cover body 1. The wind-shielding piece 3 is correspondingly provided with six wind-shielding pieces which are respectively clamped on six edges of the positioning ring 21, and the wind-shielding piece 3 can fully and omnidirectionally shield the wind blowing to the fire cover.

Referring to fig. 3, a positioning member 33 is disposed on one side of each wind-shielding sheet 3, a bayonet 333 for the positioning ring 21 to be inserted into and rotated is disposed on the positioning member 33, the wind-shielding sheet 3 is connected to the positioning ring 21 by the positioning member 33, the wind-shielding sheet 3 can rotate around the positioning ring 21, and the wind-shielding sheet 3 can be fixed at any time by friction between the positioning member 33 and the positioning ring 21 after the rotation of the wind-shielding sheet 3 is completed.

In this embodiment, the positioning member 33 specifically includes a first anchor ear 331 and a first connecting portion 332, the first connecting portion 332 is welded with the windshield 3 and the first anchor ear 331 respectively, and therefore the first anchor ear 331 is fixedly connected with the windshield 3 through the first connecting portion 332, and compared with other connecting manners, the welding manner is firmer. The bayonet 333 is the opening of first staple bolt 331, and first staple bolt 331 is equipped with damping layer 334 in bayonet 333 department, and damping layer 334's material can be damping materials such as rubber, silica gel, foamed plastic, because the toughness of this type of damping material is good, this damping layer 334 can increase the frictional force when setting element 33 and holding ring 21 relative rotation as buffer gear to make the relative rotation of setting element 33 and holding ring 21 more steady.

The support frame 2 further comprises a first stop collar 23 and a second stop collar 24. The first limiting ring 23 is disposed below the positioning ring 21 in parallel, the windshield 3 includes an upper piece 31 and a lower piece 32, the positioning piece 33 is disposed at a joint of the upper piece 31 and the lower piece 32, the outer side wall of the lower piece 32 is provided with a limiting piece 25, and the limiting piece 25 is provided with a limiting opening 253 adapted to be fastened to the first limiting ring 23. When the limiting opening 253 is fastened with the first limiting ring 23, the wind-blocking sheet 3 blocks the wind in a vertical state.

The first position-limiting ring 23 can also be disposed above the positioning ring 21, and correspondingly, the position-limiting member 25 is disposed on the inner sidewall of the upper plate 31. When the windshield 3 rotates to the vertical state, the limiting member 25 on the upper plate 31 is fastened and fixed with the first limiting ring 23. Compared with the design that the first limiting ring 23 is arranged above, the limiting member 25 is arranged below so as to be positioned at the outer side and the lower side of the wind shield 3, the temperature is relatively reduced, and the service life of the limiting member 25 can be prolonged.

The limiting member 25 includes a second hoop 251 and a second connecting portion 252, the second hoop 251 is fixedly connected to the lower sheet 32 through the second connecting portion 252, and the limiting opening 253 is an opening of the second hoop 251. In this embodiment, the second connecting portion 252 is welded to the second anchor ear 251 and the lower sheet 32, so that the welding connection is more stable compared with other connection methods. The second hoop 251 has two arc-shaped guide pieces 254 respectively extending from two opposite sides of the position-limiting opening 253, and the two arc-shaped guide pieces 254 are bent back and forth. The arc-shaped guide piece 254 can enlarge the opening of the limiting opening 253 without affecting the limiting effect, so that the first limiting ring 23 can be more easily clamped into the second hoop 251.

Referring to fig. 2 and 4, the second limiting ring 24 is disposed on one side of the positioning ring 21, in this embodiment, the second limiting ring 24 is concentrically disposed on the inner side of the positioning ring 21, and when the wind-shielding sheet 3 rotates until the lower sheet 32 abuts against the second limiting ring 24, the wind-shielding sheet 3 is in a horizontal state to get out of the air inlet. The weight of the part where the upper piece 31 is located is larger than that of the part where the lower piece 32 is located, so that the wind shield piece 3 can utilize gravity as driving force in the process of rotating from a vertical state to a horizontal state, the wind shield piece 3 keeps stress balance when rotating to the state that the lower piece 32 abuts against the second limiting ring 24, and the wind shield piece 3 can keep the horizontal state and gives way out of an air inlet.

The implementation principle of the structure of the fire cover keeps out wind in the embodiment of the application is as follows:

after the wind-guard sheet 3 is clamped on the positioning ring 21, the positioning ring 21 can rotate by taking the positioning ring 21 as an axis, the wind inlet amount in different directions is controlled by controlling the rotating angles of the wind-guard sheets 3 at different positions, and a first limiting ring 23 and a second limiting ring 24 are respectively arranged below and inside the positioning ring 21, so that the rotating angles of the wind-guard sheets 3 are limited within 90 degrees. When the wind shield 3 rotates to a vertical state, the wind shield 3 is fixedly clamped with the first limiting ring 23, and the wind shield 3 plays a role in shielding wind; because the mass of the upper piece 31 of the wind shield 3 is greater than that of the lower piece 32, when the wind shield 3 rotates to the horizontal state, the gravity center of the wind shield 3 is on the upper piece 31, and the lower piece 32 is abutted against the second limiting ring 24, so that the stress balance of the wind shield 3 is kept stable, and the state of yielding the air inlet is kept.

The above is a preferred embodiment of the present application, and the scope of protection of the present application is not limited by the above, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
