Description

Technical Field

[0001] The utility model relates to a navigation beacon light installation component, in particular to a latch used for installing the navigation beacon light. Background Art

[0002] Currently, beacon lights are usually installed by fixing them to the floating frame with bolts. However, this traditional fixing method has some obvious defects in actual use. First, when the beacon light needs to be disassembled and maintained, the bolt fixing method often takes longer time, and the disassembly and assembly process is complicated, which greatly reduces the work efficiency. In addition, since the beacon lights usually work in an aquatic environment, the moisture in the air can easily accelerate the rusting of the bolts, making it difficult to disassemble the bolts smoothly due to rust. In some cases, even forced operation due to the difficulty of disassembly will cause damage to the main body of the beacon light, increase maintenance costs and may affect the service life of the beacon light. In addition, during the water operation process, the traditional bolt fixing method has cumbersome operating steps and increases the time spent on the floating frame, which invisibly increases the danger of the workers' operation. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a latch for installing a navigation light, which is convenient to install and disassemble, can avoid the difficulty of maintenance after the traditional bolts are rusted, and can reduce safety risks.

The diameter of the core rod matches the diameter of the pin rod hole so that the core rod can move up and down. The lower part of the core rod is provided with an inwardly concave limit groove, and the upper part of the core rod is provided with an outwardly protruding limit platform. A steel ball groove is provided near the bottom end of the pin rod and radially penetrates the wall of the pin rod hole. The steel ball groove can accommodate steel balls, and the lateral depth and outer wall diameter of the steel ball groove are both smaller than the diameter of the steel ball. The limiting groove partially accommodates the steel ball, the bottom surface of the limiting platform is pressed on one end of the compression spring, and the other end of the compression spring is against the upper end of the pin rod. The upper part of the pin rod is connected to the cap through an external thread, and the top of the cap is sleeved on the upper end of the core rod and limited to the top surface of the limiting platform. When the core rod entity is located inside the steel ball groove, the outer side of the steel ball extends out of the outer wall of the pin rod, and the inner side of the steel ball is limited by the core rod entity. When the limiting groove is located inside the steel ball groove, part of the steel ball enters the limiting groove, and the steel ball is completely retracted into the outer wall of the pin rod.

[0017] Figure 2 This is a diagram showing the use status of the latch for installing a navigation light according to the present invention. DETAILED DESCRIPTION

[0018] The following is a further detailed description of the latch for installing a navigation light according to the present invention in conjunction with the accompanying drawings and specific embodiments. Example 1

[0019] like Figure 1As shown, it includes a pin rod 2 and a core rod 1 located in the longitudinal through hole of the pin rod 2. The diameter of the core rod 1 matches the diameter of the pin rod 2 so that the core rod 1 can move up and down. The lower part of the core rod 1 is provided with an inwardly concave limiting groove 4, and the upper part of the core rod 1 is provided with an outwardly protruding limiting platform 3, which can be annular or square. A steel ball groove 5 is provided near the bottom end of the pin rod 2 and radially penetrates the hole wall of the pin rod 2. The steel ball groove 5 accommodates steel balls 8. The number of steel balls 8 is at least two. The horizontal depth and outer wall diameter of the steel ball groove 5 are both smaller than the diameter of the steel ball 8 to ensure that the steel ball will not fall out. The length of the limiting groove 4 is greater than the diameter of the steel ball 8, so that only a part of the steel ball 8 enters the limiting groove 4. The bottom surface of the limit platform 3 is pressed on one end of the compression spring 7, and the other end of the compression spring 7 is against the upper end of the pin rod 2. The upper part of the pin rod 2 is connected to the cap 12 through an external thread, and the top of the cap 12 is sleeved on the upper end of the core rod 1 and limited to the top surface of the limit platform 3; when the core rod 1 is physically located inside the steel ball groove 5, the outer side of the steel ball 8 extends out of the outer wall of the pin rod 2, and the inner side of the steel ball 8 is physically limited by the core rod 1. When the limiting groove 4 is located inside the steel ball groove 5, part of the steel ball 8 enters the limiting groove 4, and the steel ball 8 is completely retracted into the outer wall of the pin rod 2; a through hole 10 is provided on the upper part of the core rod 1 near the port position, and a pull ring 11 is provided in the through hole 10 to assist in the process of pulling it out. Example 2

[0020] Different from the first embodiment, a built-in groove 6 is provided on the inner side of the upper end of the pin rod 2. The built-in groove 6 is located directly above the limit groove 4 and a spring 7 is placed inside. The built-in groove 6 provides a special accommodation space for the spring 7, so that the spring can be effectively fixed to avoid displacement or falling off due to external force, thereby ensuring the stability and reliability of the device.

[0021] Usage process: Figure 2 This is a diagram of the use state of the present invention. First, align the core rod 1 and the pin rod 2 in the latch device for installing the navigation light with the installation position. By pressing the upper end of the core rod 1, the limit groove 4 moves down to the position of the steel ball 8. A part of the steel ball 8 enters the limit groove 4, and the other part remains in the steel ball groove 5. The steel ball 8 is completely retracted into the outer wall of the pin rod 2; when the latch device reaches the installation position, loosen the upper end of the core rod 1, so that the main body of the core rod 1 is located inside the steel ball groove 5, squeeze out the steel ball 8, and no part of the steel ball 8 is in the limit groove 4. The outer side of 8 extends out of the outer wall of the pin rod 2, so that the pin rod 2 and the core rod 1 form a stable limited connection, and the pin rod 2 is firmly fixed, which can effectively prevent loosening or falling off due to external force, thereby achieving reliable fixation; when it is necessary to remove the pin, press the upper end of the core rod 1 to move the limiting groove 4 to the bottom of the steel ball groove 5, and the steel ball 8 is partially located in the limiting groove 4 and partially located in the steel ball groove 5. The steel ball 8 is completely retracted into the outer wall of the pin rod 2, and the limited fixation is released. During the removal process, the pull ring 11 can be used to assist in pulling out to complete the removal operation of the pin.
