Description

Technical Field

[0001] The utility model relates to the field of handrails, and more specifically, to an aluminum alloy handrail for a ship. Background Art

[0002] The common materials for handrails installed on ships are solid wood and stainless steel. Different materials have different properties and advantages and disadvantages. Solid wood handrails have a natural appearance, good texture, and natural atmosphere, which gives people a comfortable feeling. However, solid wood handrails are susceptible to moisture and deformation. They need to be kept dry and moisture-proof. The maintenance cost is high. They need to be waxed or painted frequently, otherwise the surface is prone to wear and scratches. Stainless steel handrails have good corrosion resistance and are not easily affected by moisture, decay, rust, etc. They will not deform or crack after long-term use. In addition, the surface of stainless steel handrails is bright, easy to clean, and not easy to accumulate dust and oil stains. They keep clean and hygienic, but their appearance is relatively monotonous, lacking the natural texture and warm atmosphere of solid wood handrails. Stainless steel handrails are relatively expensive and require a higher budget. In addition, the existing handrails installed on ships have high requirements for columns. Each handrail needs to be installed on a column of fixed specifications. When columns of different specifications are used, handrails of fixed specifications cannot meet the needs.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0019] See also Figure 1-Figure 3 The utility model is an aluminum alloy handrail for a ship, which includes a first spring 2, a first shell 3 and a second shell 4. The bottoms of the first shell 3 and the second shell 4 can be detachably mounted on a column 1. A first connecting rod 5 is fixedly connected to the upper side of one side of the second shell 4, and a second connecting rod 6 is fixedly connected to the lower side of one side of the second shell 4. A first cavity 7 with an opening is provided at the upper part of the first shell 3. One end of the first spring 2 is fixedly mounted in the first cavity 7. A slider 8 is fixedly connected to the other end of the first spring 2. The slider 8 is slidably mounted in the first cavity 7. The first connecting rod 5 is fixedly connected to the slider 8. A second cavity 9 with an opening is provided at the lower part of the first shell 3. The second connecting rod 6 is movably inserted in the second cavity 9. The distance between the first shell 3 and the second shell 4 can be adjusted by movably inserting the first connecting rod 5 and the second connecting rod 6 in the first shell 3.

[0020] A plurality of positioning holes 10 are provided above the outer surface of one side of the first shell 3, a telescopic rod 16 is fixedly installed on one side of the slider 8, a positioning block 12 is fixedly installed on the telescopic end of the telescopic rod 16, a second spring 11 is sleeved on the telescopic rod 16, one end of the second spring 11 is fixedly connected to the slider 8, and the other end of the second spring 11 is fixedly connected to the positioning block 12, and the positioning block 12 is inserted into any positioning hole 10. The surface of the top of the positioning block 12 is arc-shaped, which is convenient for the user to press to select different positioning holes 10, thereby adjusting the distance between the first shell 3 and the second shell 4. When the positioning block 12 is not pressed, it will be plugged and fixed in the positioning hole 10 by the elastic force of the second spring 11. The telescopic rod 16 ensures that the positioning block 12 only moves in the vertical direction.

[0021] The bottom of the first shell 3 and the second shell 4 are both provided with threaded holes 13, and a flat plate 14 is provided above the column 1 and is integrally formed therewith. A through hole is provided on the flat plate 14, and the first shell 3 is fixedly connected to the flat plate 14 by bolts screwed into the threaded holes 13, and the second shell 4 is fixedly connected to the flat plate 14 by bolts screwed into the threaded holes 13. The first shell 3, the second shell 2 and the flat plate 14 are disassembled by removing the bolts.

[0022] The first shell 3, the second shell 4 and the column 1 are all made of aluminum material. Compared with wooden materials, it is lighter, has higher support strength, is waterproof, moisture-proof and insect-proof, is green and environmentally friendly, has zero formaldehyde, is strong, durable, corrosion-resistant and recyclable.

[0023] The bottom of the first shell 3 and the second shell 4 are both provided with rainwater drainage grooves 15. The rainwater drainage grooves 15 can make the rainwater flowing to the bottom of the first shell 3 and the second shell 4 fall directly, preventing the rainwater from affecting the connection between the handrail and the platform 14.

[0024] The working principle of the utility model is:

[0025] When the handrail needs to be installed on the column 1 of the ship, first adjust the distance between the first shell 3 and the second shell 4 according to the distance between the two through holes in the flat plate 14 on the column 1. When adjusting, press the positioning block 12 in the positioning hole 10, at which time the second spring 11 is in a compressed state, the telescopic rod 16 is shortened, and then the second shell 4 and the first shell 3 are pulled apart, so that the first spring 2 is stretched and lengthened, and at this time the slider 8 and the positioning block 12 will follow the first connecting rod 5 to move in the direction of the second shell 4, when the threaded holes 13 of the first shell 3 and the second shell 4 correspond to the two through holes on the platform 14, it means that the hole position is successfully aligned, and then stop pulling the two shells, at this time the positioning block 12 moves to the corresponding positioning hole 10 under the force of the second spring 11 to achieve the locking of the position of the first shell 3 and the second shell 4, and finally fix the handrail and the column 1 with bolts.

[0026] The above is only a preferred embodiment of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
