Description

Technical Field

[0001] This utility model relates to the field of fire-resistant fire collars, and in particular to a fire collar that is easy to install. Background Technology

[0002] Fire collars (also called fireproof collars) are made of metal with a flame-retardant expanding core material inside. They are fitted onto the outer wall of rigid polyvinyl chloride (PVC) pipes and fixed to the floor or wall. When a fire occurs, the core material expands rapidly due to heat, squeezing the UPVC pipe and sealing the pipe opening in a short time, preventing the fire from spreading along the opening. This product has a compact structure, beautiful appearance, and organically combines leak prevention and fire protection measures.

[0003] However, during installation, the fire arrestor ring is often installed at a high position, which is very inconvenient for construction workers to hold the fire arrestor ring with one hand and install it with the other. Utility Model Content

[0004] The technical problem to be solved by this invention is to overcome the defects of the prior art and provide a fire arrestor ring that is easy to install.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an easy-to-install fire-arresting ring, comprising a fire-arresting ring body, a first ring, a second ring, and a splicing block 1. The fire-arresting ring body has a first ring on its front and a second ring on its back. A splicing block 1 is installed on the left and right sides of the first ring, and a splicing block 2 is installed on the left and right sides of the second ring. The front of each splicing block 1 and splicing block 2 has two connecting holes. Flame-retardant plates are embedded in the inner walls of the first and second rings. A fixing component is connected to the bottom of the fire-arresting ring body. The fixing component includes a handle and a clamp, which are hinged and form a fulcrum at the hinge. A clamping space is formed in the middle of the clamp, which can accommodate a pipe.

[0007] As a preferred embodiment of this utility model, the clamp opens and closes with the grip, and a reset component is provided between the grips. The reset component maintains the grip in an open state under normal conditions, and opens the grip when it is retracted.

[0008] As a preferred embodiment of this utility model, the reset assembly includes a pneumatic reset component.

[0009] As a preferred embodiment of this invention, the reset assembly includes a hydraulic reset component.

[0010] As a preferred embodiment of this utility model, a first magnetic component is attached to the lower part of the flame arrestor ring body, and a second magnetic component is attached to the opening and closing fulcrum. The first magnetic component and the second magnetic component are magnetically attracted to each other to form a quick-release mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The handle drives the clamp to grip the pipe (with pneumatic / hydraulic self-resetting), completing the flame arrestor ring fixation within 10 seconds, increasing efficiency by 300%;

[0013] 2. The magnetic quick-release structure ensures zero drop of the flame arrestor ring during high-altitude installation, while the flame-retardant plate automatically aligns with the pipe.

[0014] 3. Single-handed operation completely solves the problem of traditional installation requiring both hands to lift, reducing construction fatigue and the risk of climbing operations. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In the attached diagram, all identical reference numerals refer to the same components.

[0022] like Figure 1-3As shown, this utility model provides an easy-to-install fire arrestor ring, including a fire arrestor ring body 1, a first ring body 2, a second ring body 3, and a splicing block 4. The first ring body 2 is provided on the front of the fire arrestor ring body, and the second ring body 3 is provided on the back of the first ring body 2. A splicing block 4 is installed on the left and right sides of the first ring body 2, and a splicing block 5 is provided on the left and right sides of the second ring body 3. Two connecting holes 6 are provided on the front of the splicing block 4 and the splicing block 5 respectively. A flame-retardant plate 7 is embedded on the inner wall of the first ring body 2 and the second ring body 3. The fire arrestor ring body 1 is characterized by a fixing component 8 connected below it. The fixing component 8 includes a handle 9 and a clamping body 10. The handle 9 and the clamping body 10 are hinged and form a tension fulcrum 11 at the hinge. A clamping space is formed in the middle of the clamping body 10, which can accommodate a pipe.

[0023] In this invention, the fixing component 8 clamps onto the pipe to provide support for the flame arrestor ring body 1, eliminating the need for manual fixing by construction workers and enabling more efficient installation.

[0024] In an optional embodiment, the clamp 10 opens and closes with the grip 9, and a reset component 12 is provided between the grips 9. The reset component 12 maintains the grips 9 in an open state under normal conditions, and opens them when the grips 9 are retracted.

[0025] It should be noted that a reset component 12 is added between the grips 9; the reset component 12 normally keeps the grips 9 in the open state (at which time the clamp 10 is open); after the grips 9 are manually retracted, the reset component 12 automatically restores them to the open state; the opening and closing of the clamp 10 completely follows the opening and closing state of the grips 9.

[0026] In an optional embodiment, the reset assembly 12 includes a pneumatic reset element.

[0027] It should be noted that the pneumatic reset component uses compressed air to store energy and push the handle 9 to open;

[0028] When the grip 9 contracts, compressed air stores energy; when it releases, the air pressure releases the energy to drive the reset.

[0029] In an optional embodiment, the reset assembly 12 includes a hydraulic reset element.

[0030] It should be noted that the hydraulic reset component uses hydraulic oil damping to store energy and push the grip 9 to open;

[0031] When the grip 9 is contracted, the hydraulic oil is compressed and stored; when it is released, the oil pressure releases the energy to drive the reset.

[0032] In an optional embodiment, a first magnetic component 13 is attached to the underside of the flame arrestor ring body 1, and a second magnetic component 14 is attached to the opening and closing fulcrum 11. The first magnetic component 13 and the second magnetic component 14 are magnetically attracted to each other to form a quick release.

[0033] It should be noted that the first magnet 13 is fixedly connected to the bottom of the first ring body 2; the second magnet 14 is fixedly connected to the opening and closing fulcrum 11 of the fixing component 8; the first magnet 13 and the second magnet 14 are magnetically attracted to each other; the magnetic attraction force realizes the detachable connection between the fire arrestor ring body 1 and the fixing component 8.

[0034] The working principle of this utility model is as follows:

[0035] The construction worker holds the retraction handle 9 with one hand → the clamp 10 closes simultaneously → the clamp space is inserted into the pipe → the handle 9 is released.

[0036] Reset takes effect: The reset component 12 pushes the handle 9 to open automatically → the clamp 10 expands and hugs the outer wall of the pipe to form a stable fixation.

[0037] After the pipe is fixed by the clamp 10, the flame arrestor ring body 1 is attracted to the second magnet 14 by the first magnet 13, realizing the rapid combination of the flame arrestor ring body 1 and the fixing component 8 and providing support for the flame arrestor ring. Construction personnel no longer need to fix it by hand, and the installation work is carried out more efficiently.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
