[0020] like Figures 1 to 7A bidirectional fire protection seal is shown. It includes a cylindrical main body mating connection post 1 with a left-right central axis. The main body mating connection post 1 is made of stainless steel. A cylindrical first combination fastening hole 2 is defined on the left side of the main body mating connection post 1. A first fastening thread groove is defined on the inner cylindrical surface of the first combination fastening hole 2, which serves as the first fastening structure for the overall assembly. To the right of the first combination fastening hole 2 is a main body delivery mating hole 3 that completely penetrates the right side of the assembly, ensuring central assembly and allowing for central delivery with a delivery pipeline as needed. A cylindrical second combination fastening hole 4 is defined on the right side of the main body mating connection post 1, enabling fastening to the opposite side. The cylindrical surface of the second combination fastening hole 4 is provided with integrally formed, evenly distributed arc-shaped reinforcement stopper posts 5, enabling quick assembly at the right side by means of a snap-in mechanism. The right side of the reinforcement stopper posts 5 extends beyond the right end surface of the main body mating connection post 1, allowing insertion into the mating connection assembly during mating, ensuring a more stable fit. A locking and fitting connection groove 6 is formed between the left side of the reinforcement limit fitting column 5 and the left end face of the second combined fastening hole 4, which can be quickly locked and combined by inserting and rotating, with higher matching efficiency during connection and more convenient assembly and disassembly operations. It can achieve a two-way fastening connection when in use, with one side being combined by threaded fastening and the other side being able to achieve a quick combination by rotating the locking position. The overall installation is more convenient, the outer side is more flat, the space occupied during installation is smaller, the overall fitting connection strength is higher, the durability during use is more reliable, and the assembly is more convenient. It can replace multiple existing components for fitting and fastening connection, and can meet the needs of quick connection and installation of conveying pipeline components, and has a wider range of applications when in use.
[0021] Preferably, the diameter of the second combined fastening hole 4 is the same as the diameter of the first combined fastening hole 2, so that the stability of the overall structure is better and the combined safety during fastening is more reliable.
[0022] Preferably, the diameter of the inner arc-shaped structure of the reinforcement limit fitting column 5 is the same as the diameter of the main body conveying fitting hole 3, so that the space at the internal center position is larger, and at the same time the strength of the reinforcement limit fitting column 5 can be maximized, and the combined strength during fitting is higher.
[0023] Preferably, a spare fastening and reinforcing thread groove is provided on the inner arc of the reinforcement limit fitting column 5, which can be used to fasten the connection according to needs, and the fitting stability during connection is better.
[0024] Preferably, a matching avoidance guide structure is provided at the right outer edge of the reinforced limiting matching column 5, so that the combination space is larger during the positioning matching, the matching efficiency is higher during the matching connection, and the combination operation is more convenient.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or replacements can be made without departing from the principles described in the present invention. These improvements or replacements should also be regarded as the scope of protection of the present invention.
