It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined or illustrated in one figure, no further detailed discussion or description thereof will be necessary in the following description of the figures.

As shown in fig. 1 to 3, the present utility model provides a technical solution: an automatic storage ladder for a ship, comprising: the control mechanism 2 and the ladder body 3 are sequentially connected from top to bottom. Wherein the ladder body 3 is in a rotational connection with the control mechanism 2 via a first swivel 24. The axis of the first rotation shaft 24 is parallel to the first direction, which is parallel to the width direction of the ladder body 3. It should be clear that since the ladder is intended for ascending, the width direction of the ladder is square, i.e. parallel to the horizontal plane. In this embodiment, the ladder body 3 has two working states, which are a use state and a stowage state, respectively, and the first end of the ladder body 3 is located under the water surface when the ladder body 3 is in the use state, and the first end of the ladder body 3 is located on the water surface when the ladder body is in the stowage state. That is, when the user needs to launch the water using the ladder, the ladder body 3 can be switched to the use state, and thus the user can enter the water by means of the ladder. When the ladder is not needed, the ladder body 3 can be switched to a retracted state, and the ladder body 3 is positioned on the water surface, so that the running resistance of the ship body is not increased. And also avoids the corrosion phenomenon caused by long-term soaking of the ladder body 3 in water.

In the present utility model, the ladder body 3 may be various straight ladders that we commonly have. However, in order to enhance the practicability of the ladder of the present utility model, the ladder body 3 may be designed as a telescopic ladder that can be extended and contracted. And not only can be convenient for accomodate, can be applicable to the ship that the hull is located the higher of surface of water simultaneously.

From the above, it can be seen that the ladder body 3 is rotated to switch between the use state and the storage state. But the ladder body 3 is limited by the absence of any limiting structure. Therefore, the ladder body 3 may be less stable when the hull moves at a high speed or when the user uses the ladder body 3. For example: when the ship body moves at high speed, the ladder body 3 rotates and is automatically switched from a retracted state to a use state; alternatively, when the user uses the ladder body 3 in the use state, the ladder body 3 is liable to shake to a large extent. Therefore, the control mechanism 2 is also required to be included in the present utility model. The control mechanism 2 is used for limiting the rotation of the ladder body 3 around the first rotation shaft 24 when the ladder body 3 is in the use state and the stowage state, so as to avoid the occurrence of the above phenomena.

Therefore, it is easily conceivable that the control mechanism 2 may be any one of an electric telescopic rod, a cylinder telescopic rod, and a hydraulic telescopic rod. The above-described similar structures can each realize the function of stabilizing the ladder body 3.

Meanwhile, it is easy to associate that when the control mechanism 2 in the embodiment of the present utility model is provided in a rod-like structure that can be automatically extended and contracted. The control mechanism 2 can drive the second end of the ladder body 3 to rotate around the first rotating shaft 24. When the second end of the ladder body 3 rotates around the first rotating shaft 24, the first end of the opposite ladder body 3 can also rotate around the first rotating shaft 24, so that water outlet and water inlet are realized.

It should be clear that in the above described embodiments, the control of the ladder body 3 is facilitated. In design, the first pivot 24 needs to be closer to the second end of the ladder body 3 (relative to the first end of the ladder body 3) along the length of the ladder body 3. Furthermore, in the process of rotating the ladder body 3, the second end of the ladder body 3 is smaller in rotation amplitude, and the first end of the ladder body 3 is larger in rotation amplitude.

It should be clear that in the embodiments of the utility model, when we put the ladder body 3 in use, the length direction of the ladder body 3 is parallel to the direction one. And a direction one from the second end of the ladder body 3 to the first end. When the ladder body 3 is in the retracted state, the length direction of the ladder body 3 is parallel to the second direction. And the second direction is directed from the second end of the ladder body 3 to the first end. The included angle formed between the first direction and the second direction is more than or equal to 120 degrees and less than or equal to 180 degrees. Specifically, the included angle may be any one degree of 120 °, 130 °, 140 °, 150 °, 160 °, 170 ° and 180 °, or any degree between the two adjacent degrees.

As a preferred embodiment of the utility model, the second direction is parallel to the vertical direction.

Further, in order to make the present utility model more easily understood by those skilled in the art. As shown in fig. 1 to 3, in an embodiment of the present utility model, a specific control mechanism 2 is also proposed. The control mechanism 2 includes: a pair of control housings 21 and telescopic members 22 in one-to-one correspondence with the control housings 21, the two control housings 21 being arranged in the first direction. The telescopic part 22 can automatically retract, the first end of the telescopic part 22 is hinged with the control shell 21 through a second rotating shaft 23, the second end of the telescopic part 22 is hinged with the second end of the ladder body 3 through a third rotating shaft, and the axial leads of the second rotating shaft 23 and the third rotating shaft are parallel to the first direction.

As can be seen from fig. 3 (in which the ladder body 3 is in the stowed condition), when the telescopic member 22 is retracted, the ladder body 3 is rotated counterclockwise about the first pivot 24 until the first end of the ladder body 3 is rotated to a position below the water surface. The ladder body 3 can be switched from the stowed state to the use state at this time. Of course, it is easily conceivable that the ladder body 3 can be switched from the use state to the stowed state when the telescopic member 22 is extended.

As described above, the telescopic member 22 can be extended and contracted to realize the switching function described above. The telescopic member 22 may be any commercially available member capable of achieving telescopic motion. For example: the telescopic member 22 is any one of an electric telescopic rod, a cylinder telescopic rod and a hydraulic telescopic rod.

It is easy to conceive that in other embodiments of the present utility model, the switching between the two working states of the ladder body 3 may be achieved by means of the motor (or an equivalent alternative device/means similar to the motor) driving the ladder body 3 to rotate via the first rotation shaft 24, and will not be described herein.

It should be clear that the practicability of the ladder of the utility model is improved. In the design, the device also comprises a handrail mechanism which is arranged on the control mechanism 2 and is used for supporting a user. The handrail mechanism can be any handrail commonly found in the market, and is not described herein.

In a specific embodiment of the utility model, the armrest mechanism comprises: the U-shaped armrests 1 are in one-to-one correspondence with the control shells 21, the first ends of the U-shaped armrests 1 are used for being connected with the ship body, and the second ends of the U-shaped armrests 1 are connected with the corresponding control shells 21. Two U-shaped handrails 1 are respectively distributed on two sides of the width direction of the ladder body 3, so that a user can conveniently go up and down the ladder body 3. The safety of the ladder is improved.

It will be appreciated that the first and second ends of the U-shaped handrail 1 may be connected to the hull and control housing 21 in any manner, such as: welding, screwing, riveting, and the like. In a particular embodiment of the utility model, the first end and/or the second end of the U-shaped handrail 1 are each provided with a fixing flange 4. The U-shaped handrail 1 is fixed to the hull and the control housing 21 by means of a fixing flange 4.

Meanwhile, it should be clear that the control housing 21 may be directly welded to the hull. However, to further increase the stability of the ladder. A connection member is further provided between the two control housings 21 for enhancing the connection stability between the control housings 21 and the hull.

In the present utility model, the connection member includes a connection angle 5, and the connection angle 5 includes: the ship comprises a first extending edge and a second extending edge, wherein a connecting curve formed between the first extending edge and the second extending edge is matched with the curve of the ship edge. The first extension is intended to be connected to the control housing 21 and the second extension is intended to be connected to the brim. It is easy to understand that when the connecting curve formed between the first extending edge and the second extending edge is matched with the curve of the ship edge, the connecting angle steel 5 can be directly clamped at the edge of the ship body. And then make the jointless between angle steel 5 and the hull border, the connection is more firm.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
