[0021] like Figures 1 to 7As shown, a fire ladder sliding fastening assembly includes a cylindrical main body stabilizing fitting seat 1, the upper end of which is provided with an integrally formed fastening connection combination column 2, which constitute the main body of the fastening assembly. The upper end of the fastening connection combination column 2 is provided with a fastening connection threaded slot 3, which can be used as a fastening hole for connection and fitting when in use. The front of the main body stabilizing fitting seat 1 is provided with a sliding fitting connection groove 4 that completely penetrates the front-to-back direction, and the lower end of the sliding fitting connection groove 4 is provided with a downward-opening avoidance fitting safety groove 5 that completely penetrates the entire front-to-back direction, which can be used to cooperate with the slide rail assembly for associated fitting, and can stably slide the connection and fastening position when in use. The lower end of the main body stabilizing fitting seat 1 is provided with an arc-shaped lubricating stabilizing fitting groove 6, which can be provided with lubricating liquid or lubricating paste when in use, so that the sliding fit is smoother, the wear resistance is better, and the safety is more reliable when in use. The lubricating and stabilizing fitting groove 6 is in communication with the sliding fitting connection groove 4. The depth of the lubricating and stabilizing fitting groove 6 is the same as the depth of the avoidance fitting safety groove 5, which improves the structural stability and is also easier to manufacture and process. During use, it can fasten and connect the fastening components, and through the sliding structure provided on the main structure, it can move simultaneously with the extended slide rail of the fire ladder. During use, it has a stronger load-bearing capacity, making the fastening component connection position stronger and more durable during use, and can ensure reliable safety when the fire ladder is extended to a relatively long length. It can be used in conjunction with a variety of sliding components during use, and has a wider range of applications.
[0022] Preferably, the cross-section of the fastening connection combination column 2 is a regular hexagonal structure, which can be fastened in conjunction with a clamping tool during fastening, and can be fastened and connected like a fastening nut, and can be used instead of existing nuts.
[0023] Preferably, the projection of the fastening connection combination column 2 in the up-down direction does not exceed the area of the projection of the main body stable matching seat 1 in the up-down direction, so that the space occupied by the overall structure is smaller and the matching stability during use is more reliable.
[0024] Preferably, the sliding fitting connection groove 4 and the avoidance fitting safety groove 5 are each provided with two groups, and are symmetrically distributed in the left and right directions of the main body stable fitting seat 1, which makes them more flexible when used in combination. A structure in one position can be selected for use in combination, or two combined structures can be selected for use in combination at the same time, which can meet the connection requirements of various combined position fitting structures.
[0025] Preferably, the front and rear edge positions of the sliding fitting connection groove 4 are provided with a chamfered structure for convenient installation and assembly, which is more convenient during assembly and assembly, has a fitting guide function, and can improve the fitting efficiency during assembly.
[0026] Preferably, the central axis of the arc-shaped structure of the lubricating stable fitting groove 6 is the same as the central axis of the main body stable fitting seat 1, which is more convenient during production and processing, has better structural stability, and can further improve the overall durability during use.
