Description

Technical Field

[0001] This utility model relates to the technical field of clamping device operating levers, specifically a hatch cover clamping device operating lever. Background Technology

[0002] As an important means of water transport, the hatch covers of ships play a crucial role in protecting the cargo inside the holds from rain and seawater. When the hatch covers are closed, the sealing strips on the hatch covers must fit tightly against the hatch coaming to create a good seal and prevent external liquids from entering the cargo holds.

[0003] Because the space below the hatch coaming of bulk carriers is narrow, the distance between the hatch cover clamp and pipes such as cable pipes, hydraulic pipes and fire water pipes is very small. When the hatch cover clamp is pressed down, the conventional clamp operating rod will interfere with the piping system and cannot be pressed down. Therefore, a hatch cover clamp operating rod is proposed. Utility Model Content

A rotating block is fixedly connected to the head of the central rod, and the rotating block is fixedly sleeved on the outer surface of the rotating shaft. A fixing box is fixedly connected to one side of the outer surface of the handle, and a through groove is formed inside the fixing box. A limiting mechanism for limiting the rotation shaft is provided inside the through groove.

A plurality of limiting grooves arranged in a circular array are opened on the outer surface of the rotating shaft. The limiting plate is adapted to the limiting grooves. An adjusting plate is movably sleeved on the outer surface of the push rod. A blocking plate for blocking the adjusting plate is fixedly sleeved on the outer surface of the push rod. A first spring is fixedly connected between the adjusting plate and the push head. The first spring is sleeved on the outside of the push rod.

[0008] As a further explanation of this utility model, the grip and the connector are connected by an installation mechanism.

[0009] As a further explanation of this utility model, the installation mechanism includes an installation groove at the tail end of the middle rod, an installation block is fixedly connected to the side of the connector facing the middle rod, a limiting rod is movably inserted into the outer surfaces of both the front and rear sides of the middle rod, a connecting groove is opened on the outer surfaces of both the front and rear sides of the installation block, the limiting rod is movably inserted into the inside of the connecting groove, a disc is fixedly connected to the outer surface of the limiting rod, and a third spring is fixedly connected between the disc and the middle rod.

[0014] As a further explanation of this utility model, the limiting rod is a rectangular rod, and the connecting groove is a rectangular groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to the following: Figures 1-8This utility model provides a technical solution: a hatch cover clamping device operating lever, including a central lever 1, a handle 2 at the head of the central lever 1, and a connector 3 at the tail of the central lever 1 that inserts into a groove on the surface of the clamping device. A U-shaped groove is formed on the outer surface of the handle 2, and a rotating shaft 4 rotatably passes through the interior of the U-shaped groove. A rotating block 5 is fixedly connected to the head of the central lever 1, and the rotating block 5 is fixedly sleeved on the outer surface of the rotating shaft 4. A fixing box is fixedly connected to one side of the outer surface of the handle 2, and a through groove is formed inside the fixing box. The part is equipped with a limiting mechanism 7 for limiting the rotation shaft 4. The inside of the fixed box is provided with a receiving groove above the through groove. The receiving groove is provided with a blocking mechanism 8. Specifically, the included angle between the grip rod 2 and the middle rod 1 is adjusted, and the included angle between the grip rod 2 and the middle rod 1 is limited by the limiting mechanism 7. After the angle between the middle rod 1 and the grip rod 2 is adjusted, the connector 3 is inserted into the groove of the hatch cover clamp, and the clamp is locked by applying force to the grip rod 2. When clamping, the lever principle is used, which is relatively labor-saving.

[0021] As a further explanation of this utility model, the limiting mechanism 7 includes a push rod 701 movably inserted into one side of the fixed box. A limiting plate 703 is fixedly connected to one side of the push rod 701 inside the fixed box. A plurality of limiting grooves 6 arranged in a circumferential array are opened on the outer surface of the rotating shaft 4. The limiting plate 703 is adapted to the limiting grooves 6. An adjusting plate 704 is movably sleeved on the outer surface of the push rod 701. A blocking plate 706 for blocking the adjusting plate 704 is fixedly sleeved on the outer surface of the push rod 701. A first spring 705 is fixedly connected between the adjusting plate 704 and the push head 702. The first spring 705 is sleeved on the outside of the push rod 701. Specifically, by pushing the push rod 701, the push rod drives the push head 702 to make the limiting plate 703 insert into the corresponding limiting groove 6, thereby limiting the rotating shaft 4.

[0022] As a further explanation of this utility model, the blocking mechanism 8 includes a fixed disk fixed inside the receiving groove. A blocking rod 801 is movably inserted into the outer surface of the fixed disk. A support disk 802 is fixedly sleeved on the outer surface of the blocking rod 801. A second spring 803 is provided between the support disk 802 and the fixed disk. The second spring 803 is sleeved outside the blocking rod 801. Specifically, as the pushing head 702 is pushed in, it presses against the blocking rod 801, causing the second spring 803 to move upward. When the other end of the pushing head 702 passes the blocking rod 801, the second spring 803 resets, causing the blocking rod 801 to reset, thus limiting one end of the pushing head 702. The blocking rod 801 limits the push head 702. When it is necessary to release the limit on the rotating shaft 4, the push rod is pushed inward again, so that the adjusting plate 704 contacts the blocking rod 801. As the push rod is pushed in, the adjusting plate 704 contacts the inclined surface of the blocking rod 801 and squeezes the blocking rod 801 to move upward, causing the second spring 803 to deform until the adjusting plate 704 passes through the blocking rod 801. Then the push rod is pulled backward, and the inclined end of the adjusting plate 704 contacts the blocking rod 801 and squeezes the blocking rod 801 to move upward, so that the push head 702 disengages from the surface of the blocking rod 801 and passes through the blocking rod 801, so that the limiting plate 703 disengages from the inside of the limiting groove 6, thereby releasing the limit on the rotating shaft 4.

[0023] As a further explanation of this utility model, the connection section between the push rod 701 and the fixed box is rectangular. Specifically, by the cooperation between the push rod 701 and the rectangular section of the fixed box, the push rod 701 is blocked by the rectangular frame, preventing it from rotating inside the fixed box, thereby enabling stable positioning of the rotating shaft 4.

[0024] As a further explanation of this utility model, both sides of the adjusting disk 704 are inclined, and the pushing head 702 is a hemispherical shape with its round head facing the rotating shaft 4. Specifically, through the hemispherical pushing head 702 and the inclined edge of the adjusting disk 704, the blocking rod 801 can be gradually squeezed upward when the round head of the pushing head 702 and the inclined end of the adjusting disk 704 come into contact with the inclined surface of the blocking rod 801.

[0025] As a further explanation of this utility model, the depth of the limiting groove 6 is greater than the length of the limiting plate 703. Specifically, after the pushing head 702 drives the limiting plate 703 to be inserted into the interior of the limiting groove 6, there is still space inside the limiting groove 6 to accommodate the pushing of the limiting plate 703.

[0026] As a further explanation of this utility model, the blocking rod 801 has an inclined surface on the side away from the rotating shaft 4. Specifically, by setting the inclined surface of the blocking rod 801, the pushing head 702 and the adjusting plate 704 can slowly press the blocking rod 801 upward when they come into contact with the inclined surface of the blocking rod 801, causing the third spring 904 to deform.

[0027] In the specific implementation process, the angle between the grip rod 2 and the middle rod 1 is adjusted according to the actual hatch conditions. The angle between the grip rod 2 and the middle rod 1 is limited by the limiting mechanism 7. After the angle between the middle rod 1 and the grip rod 2 is adjusted, the connector 3 is inserted into the groove of the hatch cover clamping device. Applying force downward to the grip rod 2 can lock the clamping device. When clamping, the lever principle is used, which is relatively labor-saving. When limiting, by pushing the push rod 701, the push rod drives the push head 702 to make the limiting plate 703 insert into the corresponding limiting groove 6, thus limiting the rotating shaft 4. When pushing the push head 702, the push head 702 contacts the blocking rod 801. As the push head 702 is pushed in, it squeezes the blocking rod 801, causing the second spring 803 to move upward. When the other end of the push head 702 passes the blocking rod 801, the second spring 803 moves upward. The second spring 803 resets, causing the blocking rod 801 to reset and limiting one end of the push head 702. When it is necessary to release the limitation on the rotating shaft 4, the push rod is pushed inward again, causing the adjusting plate 704 to contact the blocking rod 801. As the push rod is pushed in, the adjusting plate 704 contacts the inclined surface of the blocking rod 801 and squeezes the blocking rod 801 upward, causing the second spring 803 to deform until the adjusting plate 704 passes through the blocking rod 801. Then the push rod is pulled backward, and the inclined end of the adjusting plate 704 contacts the blocking rod 801 and squeezes the blocking rod 801 upward, causing the push head 702 to detach from the surface of the blocking rod 801 and pass through the blocking rod 801, causing the limiting plate 703 to detach from the inside of the limiting groove 6, thereby releasing the limitation on the rotating shaft 4.

[0028] Example 2: Please refer to the following: Figures 1-8 This utility model provides a technical solution: the grip 2 and the connector 3 are connected by an installation mechanism 9.

[0029] As a further explanation of this utility model, the installation mechanism 9 includes an installation groove 901 opened at the tail end of the middle rod 1. An installation block is fixedly connected to the side of the connector 3 facing the middle rod 1. Limiting rods 902 are movably inserted into the outer surfaces of the front and rear sides of the middle rod 1. Connecting grooves 903 are opened on the outer surfaces of the front and rear sides of the installation block. The limiting rods 902 are movably inserted into the interior of the connecting grooves 903. A disc is fixedly connected to the outer surface of the limiting rods 902. A third spring 904 is fixedly connected between the disc and the middle rod 1. Specifically, when pressing different models of hatch covers, different connectors 3 are replaced. At this time, the disc is pulled to disengage the limiting rods 902 from the interior of the connecting grooves 903, releasing the limiting of the installation block at the rear of the connector 3, thereby removing the connector 3. Different connectors 3 are replaced according to different models of hatch covers so that the connector 3 corresponds to the groove of the hatch cover presser.

[0030] As a further explanation of this utility model, the limiting rod 902 is a rectangular rod, and the connecting groove 903 is a rectangular groove. Specifically, by setting the rectangular limiting rod 902 and the rectangular connecting groove 903, when the limiting rod 902 is inserted into the rectangular groove, it is limited by the rectangle to prevent the limiting rod 902 from rotating, thereby preventing the connector 3 from driving the mounting block to rotate on the surface of the limiting rod 902.

[0031] In the specific implementation process, when tightening different models of hatch covers, different connectors 3 are replaced. At this time, the disc is pulled to disengage the limit rod 902 from the inside of the connecting groove 903, thereby releasing the limit on the mounting block at the rear of the connector 3 and taking out the connector 3. Different connectors 3 are replaced according to different models of hatch covers so that the connector 3 corresponds to the groove of the hatch cover clamp.

[0032] Working Principle: In use, this invention adjusts the angle between the gripping rod 2 and the central rod 1 according to the actual hatch conditions. The limiting mechanism 7 limits the angle between the gripping rod 2 and the central rod 1. After the angle between the central rod 1 and the gripping rod 2 is adjusted, the connecting head 3 is inserted into the groove of the hatch cover clamp. Applying downward force to the gripping rod 2 locks the clamp. The clamping action utilizes the lever principle, making it relatively labor-saving. During limiting, pushing the push rod 701 causes the push rod to drive the push head 702, causing the limiting plate 703 to insert into the corresponding limiting groove 6, thus limiting the rotating shaft 4. When the push head 702 is pushed, it contacts the blocking rod 801. As the push head 702 is pushed in, it presses against the blocking rod 801, causing the second spring 803 to move upward. When the other end of the push head 702 passes the blocking rod 801... The second spring 803 resets, causing the blocking rod 801 to reset and limit one end of the push head 702. When it is necessary to release the limit on the rotating shaft 4, the push rod is pushed inward again, causing the adjusting plate 704 to contact the blocking rod 801. As the push rod is pushed in, the adjusting plate 704 contacts the inclined surface of the blocking rod 801 and squeezes the blocking rod 801 upward, causing the second spring 803 to deform until the adjusting plate 704 passes through the blocking rod 801. Then the push rod is pulled backward, and the inclined end of the adjusting plate 704 contacts the blocking rod 801 and squeezes the blocking rod 801 upward, causing the push head 702 to detach from the surface of the blocking rod 801 and pass through the blocking rod 801, causing the limiting plate 703 to detach from the inside of the limiting groove 6, thereby releasing the limit on the rotating shaft 4.

[0033] When tightening different models of hatch covers, replace different connectors 3. At this time, pull the disc to disengage the limit rod 902 from the inside of the connecting groove 903, release the limit on the mounting block at the rear of the connector 3, and then remove the connector 3. Replace different connectors 3 according to different models of hatch covers, so that the connector 3 corresponds to the groove of the hatch cover clamp.

[0034] Although embodiments of the present invention 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 to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
