The above device has a poor closing effect on the hatch cover and is difficult to open. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, when the above device closes the hatch cover, the closing effect of the hatch cover is poor, and multiple steps are required to lock the hatch cover.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is:

[0006] A hatch cover with good closing effect is used to close a ship cabin body to ensure the tightness of the cabin body, and includes a cabin body, a hatch cover, a pressing member, and a spring lock; an inwardly extending bearing surface is formed at the upper end of the hatch cover, and a connecting surface is formed by further extending the bearing surface upward. The pressing member is installed on the bearing surface, the hatch cover is arranged on the connecting surface, the pressing member is fixed on the cabin body, the spring lock includes a locking member and a fixing member, the locking member is arranged on the hatch cover, and the fixing member is arranged on the cabin body.

[0007] Furthermore, the clamping member includes a clamping cross bar, a handle and a clamping member, the left end of the clamping cross bar is fixed on the bearing surface, the right end of the clamping cross bar is provided with a clearance notch, and the clamping member is fixed to the bearing surface by bolts.

[0008] The design of the clamping cross bar can ensure close contact between the hatch cover and the cabin body, improve the sealing performance by applying appropriate pressure, and reduce air or water leakage. The presence of the handle allows the operator to easily move the clamping cross bar, which is convenient for quickly locking or unlocking the hatch cover and improving work efficiency. The left end of the clamping cross bar is fixed on the bearing surface, and the notch design on the right end can adapt to the edges of cabin bodies of different sizes to ensure the stability and reliability of the entire structure. The clamping piece is fixed to the bearing surface by bolts, and its position can be adjusted according to actual needs to better adapt to different sealing requirements. The clamping cross bar and the clamping piece are made of strong materials, which can withstand greater pressure and are not easily damaged, thus extending the service life. Since the clamping piece is fixed by bolts, it can be easily disassembled and installed when maintenance or replacement is required, reducing maintenance costs. The coordinated use of the clamping cross bar and the clamping piece can ensure that the hatch cover remains stable in the closed state and improve safety, especially in severe weather conditions.

[0009] Furthermore, the clamping member includes an operating handle, a connecting rod and a connecting member, the connecting member is welded to the bearing surface, the operating handle is connected to the connecting rod, and the connecting rod is hinged to the connecting member by bolts.

[0010] Through the combined use of the operating handle, connecting rod and connecting piece, sufficient pressure can be generated when the hatch cover is closed to ensure close contact between the hatch cover and the cabin body, thereby improving the sealing performance. The design of the operating handle allows the operator to easily move the connecting rod to quickly lock or unlock the hatch cover, thereby improving work efficiency. The connecting piece is welded on the bearing surface to ensure the stability and reliability of the entire structure, and can withstand external pressure and impact force. The connecting rod is hinged to the connecting piece by bolts, and its position can be adjusted as needed to adapt to different sealing requirements. The various parts of the clamping piece are made of strong materials, which can withstand greater pressure and are not easily damaged, thereby extending the service life. Since the clamping piece is hinged by bolts, it can be easily disassembled and installed when maintenance or replacement is required, thereby reducing maintenance costs.

[0011] Furthermore, a sealing strip is provided on the inner side of the hatch cover.

[0012] The sealing strip can fill the gap between the hatch cover and the hatch body, ensuring that a sealed space can be formed when the hatch cover is closed, preventing the penetration of moisture, gas or other substances. The sealing strip is usually made of materials with good weather resistance, which can maintain its performance under various climate conditions, ensuring the sealing effect after long-term use. The sealing strip can absorb the vibration between the hatch cover and the hatch body, reduce the noise generated by the opening and closing of the hatch cover, and also help to reduce the vibration inside the hatch body. When the hatch cover is closed, the sealing strip can also play a buffering role, reducing the direct collision between the hatch cover and the hatch body, and protecting the surface of the hatch body from damage. The sealing strip can prevent the transfer of heat, helping to maintain the temperature stability inside the hatch body and reducing the influence of the external environment on the temperature inside the hatch. For ships in the marine environment, the sealing strip can effectively block the intrusion of salt and seawater, reducing the corrosion risk of the internal components of the hatch body.

[0013] Further, the handle on the pressing crossbar can also be set as a tightening handle. The lower end of the tightening handle is a bolt structure. The tightening handle penetrates through the pressing crossbar, and a positioning hole adapted to the tightening handle is provided on the hatch cover.

[0014] The tightening handle can provide additional pressure to ensure the close contact between the hatch cover and the hatch body, thereby improving the sealing performance. The design of the tightening handle enables the operator to easily adjust the position of the pressing crossbar. By rotating the tightening handle, the locking or unlocking of the hatch cover can be achieved, improving the work efficiency. Through the threaded structure of the tightening handle, the pressure between the hatch cover and the hatch body can be precisely adjusted to ensure the best sealing effect. The connection between the tightening handle and the pressing crossbar enhances the stability of the entire structure, helping to withstand external pressure and impact force. The tightening handle can be adjusted according to needs to adapt to different sealing requirements, ensuring the sealing effect of the hatch cover under different conditions. The tightening handle is made of strong materials and can withstand large pressure without being easily damaged, extending its service life. Since the tightening handle penetrates through the pressing crossbar through a bolt structure, it can be easily disassembled and installed when maintenance or replacement is required, reducing the maintenance cost.

[0015] Further, the fixing part is fixed on the hatch body by screws.

[0016] Fixing by screws can ensure a more firm connection between the fixing part and the hatch body, improving the stability of the entire system. Using high-quality screws can ensure the durability of the connection part, reducing failures caused by loose or damaged screws. When the fixing part needs to be replaced or maintained, only the screws need to be unscrewed, reducing the maintenance cost. The firm fixing part can ensure that the hatch cover remains stable in the closed state, improving safety, especially in bad weather conditions. Compared with other fixing methods such as welding, using screws for fixing is more economical in terms of cost and can also ensure good performance.

[0017] The utility model has the following beneficial effects:

[0018] 1. Through the design of the pressing member, especially the coordinated work of the pressing cross bar, the handle and the clamping member, the utility model can ensure the close contact between the hatch cover and the hatch body, significantly improve the sealing performance, effectively reduce the leakage of moisture or gas, and the use of the sealing strip further enhances the sealing effect of the hatch cover, ensuring that a completely enclosed space can be formed when the hatch cover is in the closed state;

[0019] 2. The combined use of the operating handle, the connecting rod and the connecting member enables the operator to easily move the connecting rod, realizing the functions of quickly locking or unlocking the hatch cover, improving the work efficiency. By moving the operating handle, the pressing cross bar is loosened, and the hatch cover can be opened and closed by unlocking the spring lock, greatly reducing the operation time;

[0020] 3. The handle can also be set as a tightening handle to further lock the hatch cover and ensure the closing effect of the hatch body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further details the utility model in conjunction with the drawings and specific preferred embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the components, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example and do not limit the protection scope of the present utility model.

[0029] Embodiment 1: Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , it can be seen that this device is used for the ship's hull to ensure that the hatch cover has a good closing effect. The existing hatch cover has a poor closing effect, and in extreme cases, the hatch cover will open. Therefore, in order to improve the closing effect of the hatch cover, a hatch cover with a good closing effect is proposed, which includes a hull 1 that constitutes the main body of the device. A hatch cover 2 is provided on the hull 1. The hatch cover 2 is hinged to the upper end of the hull 1. The two ends of the hull 1 extend inward to form a bearing surface 11, and the bearing surface 11 continues to extend upward to form a connecting surface 12. A pressing member 3 is fixed on the left bearing surface 12 by bolts. A spring lock 4 is also provided on the front of the hull 1. The locking member 41 of the spring lock 4 is fixed on the hatch cover 2 by screws, and the fixing member 42 is fixed on the hull 1 by bolts. When in use, the hatch cover 2 is rotated downward along the hinge point until the hatch cover 2 is in close contact with the connecting surface 12 on the hull 1. The pressure is adjusted by the pressing member 3 to ensure the close contact between the hatch cover 2 and the hull 1. The pressing member 3 is fixed on the bearing surface 11 by bolts, and the pressure can be adjusted by adjusting the position of the pressing member 3. Once a good contact is formed between the hatch cover 2 and the hull 1, the spring lock 4 is used for locking. The locking member 41 (located on the hatch cover 2) is aligned with the fixing member 42 (located on the hull 1), and then the two are locked together through the mechanical structure of the spring lock 4. When the hatch cover needs to be opened, first unlock the spring lock 4 to separate the locking member 41 from the fixing member 42, then release the pressure through the pressing member 3 to make the contact between the hatch cover 2 and the hull 1 become loose. Finally, lift the hatch cover 2 and rotate it upward along the hinge point to complete the opening process;

[0030] Through the design of the pressing member 3 and the spring lock 4, it can be ensured that there is a close contact between the hatch cover 2 and the hull 1, improving the sealing performance. The use of the spring lock 4 makes the locking and unlocking process of the hatch cover simple and fast, improving the operation efficiency. The fixing methods of the pressing member 3 and the spring lock 4 ensure the stability of the hatch cover structure, and the structure can remain intact even under harsh conditions.

[0031] Embodiment 2: Compared with Embodiment 1, Embodiment 2 further improves the closing effect of the clamping member 3 on the hatch cover 2 by providing a clamping cross bar 31 and a clamping member 33. Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that one end of the clamping cross bar 31 is welded on the bearing surface 11, and a clearance gap is set at the other end for placing the clamping member 33. The connecting rod 332 of the clamping member 33 is hinged on the connecting member 333, and the connecting member 333 is welded on the hatch cover 2. The operating handle 331 is mounted on the connecting rod 332, and the connecting rod 332 can also be mounted with an anti-slip cover;

[0032] When in use, first, rotate the hatch cover 2 downward along the hinge point until the hatch cover 2 is in close contact with the connecting surface 12 on the cabin body 1 to ensure that the hatch cover 2 and the cabin body 1 form a good contact, and use the clamping cross bar 31 to ensure that the contact between the hatch cover 2 and the cabin body 1 is closer. One end of the clamping cross bar 31 is welded to the bearing surface 11, and the other end is provided with a clearance notch for placing the clamping piece 33. The position of the clamping piece 33 is adjusted by operating the handle 331 so that the connecting rod 332 is aligned with the clearance notch on the clamping cross bar 31. After the connecting rod 332 is aligned with the clearance notch on the clamping cross bar 31 , use the operating handle 331 to apply force to rotate the connecting rod 332 around the connecting piece 333, further compressing the hatch cover 2, use the spring lock 4 for final locking, align the locking piece 41 (located on the hatch cover 2) with the fixing piece 42 (located on the cabin body 1), and then lock the two together through the mechanical structure of the spring lock 4, unlock the spring lock 4, separate the locking piece 41 from the fixing piece 42, release the pressure on the connecting rod 332 by operating the handle 331, and relax the contact between the hatch cover 2 and the cabin body 1, and finally, lift the hatch cover 2 and rotate it upward along the hinge point to complete the opening process;

[0033] By using the clamping cross bar 31 and the clamping member 33 in combination, close contact between the hatch cover 2 and the cabin body 1 can be ensured, the sealing performance can be improved, and the leakage of moisture or gas can be reduced. The design of the operating handle 331 allows the operator to easily move the connecting rod 332 to achieve the function of quickly locking or unlocking the hatch cover, which greatly improves the operating efficiency and convenience and reduces the operating time.

[0034] Embodiment 3: Compared with Embodiment 1 and Embodiment 2, the hatch cover 2 has poor sealing effect after closing. In order to enhance the sealing effect of the hatch cover 2, a sealing strip is provided at the place where the hatch cover 2 contacts the cabin body 1, thereby enhancing the sealing effect of the hatch cover 2.

[0035] Embodiment 4: The difference from Embodiment 2 is that the handle 32 on the pressing crossbar 31 only provides the effect of moving the pressing crossbar away and cannot further press the hatch cover 2. Therefore, in this embodiment, the handle 332 is set as a tightening handle. The lower end of the tightening handle is a bolt structure, and corresponding positioning holes are provided on the hatch cover 2. When it is necessary to close the hatch cover 2, rotate the tightening handle so that the tightening handle presses down against the hatch cover 2 to further fix the hatch cover 2 and the cabin body 1.

[0036] By using the tightening handle, the hatch cover 2 can be further pressed, ensuring close contact between the hatch cover 2 and the cabin body 1, improving the sealing performance, reducing the leakage of moisture or gas. The design of the tightening handle enables the operator to easily adjust the pressure, realizing the functions of quickly locking or unlocking the hatch cover, greatly improving the operation efficiency and convenience, and reducing the operation time.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
