Technical Field

[0001] This utility model relates to the field of marine railing technology, and in particular to a multifunctional marine railing. Background Technology

[0002] Railings are usually installed on the upper part of ships to protect the safety of the crew, but traditional railings on ships are mostly simple in structure.

[0003] In addition, current ships are typically equipped with gillnets, high-pressure water cannons, and other equipment to defend against pirates attempting to board. However, pirates often use grappling hooks, hooking onto the ship's railings and then climbing up the ropes to complete their boarding. Therefore, it is necessary to design a multi-functional railing that can protect crew members from accidental falls while also providing defensive capabilities. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a multifunctional marine railing.

[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] like Figures 1-6 The multifunctional marine railing shown includes a horizontal bar 1 and multiple vertical bars 2 located on the lower side of the horizontal bar 1. A first cavity 3 is provided on the outer side of the horizontal bar 1. Several rotating shafts are evenly distributed and rotatably installed in the first cavity 3 along the length direction of the horizontal bar 1. A first spike 5 is provided on the rotating shaft. A driving mechanism is also provided in the first cavity 3. The driving mechanism is used to drive the rotating shaft to rotate, so that the first spike 5 extends out of the first cavity 3 or is stored in the first cavity 3.

[0024] According to the above structure, by movably setting the first spike 5 on the crossbar 1, when the ship needs to carry out defensive work, the rotating shaft can be driven by the drive mechanism to rotate, so that the first spike 5 extends outward from the first cavity 3, which can effectively prevent pirates from climbing over the railing to complete the boarding work, and greatly improve the practicality of the railing.

[0025] See Figure 3 , Figure 6 As shown, the driving mechanism includes a gear 21 coaxially mounted on the rotating shaft, and a rack 22 that can mesh with the gear 21 sliding in the first cavity 3; during operation, the movement of the rack 22 and its meshing with the gear 21 drive the gear 21, the rotating shaft and the first spike 3 to rotate, and cause the first spike 3 to extend outward.

[0026] See Figure 4 , Figure 5 As shown, a transverse sliding groove 41 communicating with the first cavity 3 is provided on one side of the crossbar 1, and a sliding seat 42 is provided on the rack 22. The sliding seat 42 is slidably disposed in the transverse sliding groove 41, and a push-pull plate 43 is provided at the outer end of the sliding seat 42. The rack 22 is slidable by the push-pull plate 43 being moved by hand.

[0027] Furthermore, a locking pin 31 is movably inserted into the push-pull plate 43, and locking holes 32 are provided at intervals on the crossbar 1 for the locking pin 31 to be inserted into. That is, there are two locking holes 32. One locking hole 32 cooperates with the locking pin 31 to keep the first spike 5 retracted in the first cavity 3, while the other locking hole 32 cooperates with the locking pin 31 to keep the first spike 5 protruding from the first cavity 3.

[0028] See Figure 1 , Figure 4 , Figure 6 As shown, a second cavity 51 communicating with the first cavity 3 is provided at the upper end of the upright 2. A rotating column 52 is rotatably installed in the second cavity 51. A second spike 53 is provided on the rotating column 52. A third cavity 54 communicating with the second cavity 51 is provided on the outside of the upright 2. The second spike 53 is located in the third cavity 54. A transmission mechanism is connected between the rotating column 52 and the rack 22. The transmission mechanism can drive the rotating column 52 to rotate by the movement of the rack 22, so that the second spike 53 can extend out of the third cavity 54 or be stored in the third cavity 54.

[0029] When the rack 22 slides and drives the first spike 5 to extend out of the first cavity 3, under the action of the transmission mechanism, it can simultaneously drive the second spike 53 to extend out of the third cavity 54, further improving the defensive effect.

[0030] Furthermore, the transmission mechanism includes an extension seat 61 located on the lower side of the rack 22. The lower end of the extension seat 61 extends into the second cavity 51, and a guide post 62 is provided on one side. A spiral groove 63 is provided on the outer wall of the rotating post 52, and one end of the guide post 62 is located in the spiral groove 63.

[0031] The sliding of the rack 22 causes the guide post 62 to move in the spiral groove 63, thereby causing the rotating post 52 to rotate and causing the second spike 53 to extend outward.

[0032] In this invention, an mounting plate 71 is provided at the lower end of the upright 2; the upright 2 is fixed to the ship by the mounting plate 71.

[0033] In this utility model, a plurality of connecting rods 81 are connected between two adjacent uprights 2.
