Description

Technical Field

[0001] The utility model relates to the technical field of sealed hatches, and specifically relates to a hatch pressing mechanism and a sealed hatch. Background Technique

[0002] The steel airtight door is a door made of steel materials, mainly used to prevent the influence of external factors (such as sand, dust, moisture, etc.) on the internal environment, and at the same time has good airtight performance.

[0003] However, in the existing technical field of sealed hatches, the pressing and sealing of the hatch are crucial. Traditional hatch pressing mechanisms often have complex structures and cumbersome operations. After long-term use, these mechanisms are prone to problems such as loosening and wear, resulting in the hatch being unable to close tightly, thus affecting the environmental control and safety performance inside the hatch. Most of the existing sealed hatches are provided with a knob disk, making it inconvenient to lock the sealed hatch.

[0004] Therefore, the utility model proposes a hatch pressing mechanism and a sealed hatch. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hatch pressing mechanism and a sealed hatch to solve the existing problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hatch pressing mechanism includes a door frame;

[0007] The outside of the door frame is fixed on the surface of the sealed door through a hinge block. A locking block is fixed on the outside of the door frame. A through hole is opened inside the locking block, and a bottom plate is fixed on the outside of the sealed door. An integrated cavity shell is arranged on the outside of the bottom plate. An extrusion rod is movably arranged inside the cavity shell. An integrated plug lock rod is arranged at the end of the extrusion rod, and the outer surface of the plug lock rod is inserted into the through hole of the locking block.

[0008] Preferably, first pin shafts integrally formed are arranged on both the upper and lower surfaces of the cavity shell. The outside of the first pin shafts is sleeved in the bottom through holes of the adjusting plate, and two groups of through holes are provided, and the two groups of through holes are symmetrical about the center axis of the adjusting plate. The through holes of the adjusting plate are sleeved on the outside of the second rotating pin. The bottom end of the second rotating pin is integrally formed on the outer surface of the rotating handle. Through holes are opened on both the upper and lower surfaces of the rotating handle. The through holes of the rotating handle are sleeved on the surface of the fixed rotating rod, and the surface of the fixed rotating rod is fixed inside the extrusion rod.

[0009] Preferably, the cross-section of the extrusion rod is in a "square" shape structure. The central axis of the extrusion rod coincides with the central axis of the through hole in the locking block on the same horizontal line, and the radius size of the through hole in the locking block is equal to the end face radius of the plug lock rod.

[0010] Preferably, the adjusting plate is located near the surface of the cavity shell, and the adjusting plate is configured in two sets, with the two sets of adjusting plates being symmetrical about the central axis of the cavity shell.

[0011] Preferably, the upper and lower surfaces of the extrusion rod are provided with a first guide groove, and the first guide groove and the second guide groove are correspondingly arranged. The second guide groove is opened in the cavity shell, and the first guide groove and the second guide groove are rolled balls.

[0012] Preferably, the outer surface of the adjusting plate is in close contact with the first guide groove and the second guide groove, and the cross-section of the ball is circular.

[0013] Preferably, a sealed hatch includes the hatch clamping mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by sleeved the outer part of the second pivot pin inside the adjusting plate, when the handle is pressed to rotate it along the central axis of the second pivot pin, the adjusting plate rotates along the central axis of the first pivot pin. Therefore, the handle pushes the pressing rod to the left in the cavity, so that the outer part of the locking rod is inserted into the through hole of the locking block, thus achieving a sealing lock between the door frame and the sealing door. By opening a second guide groove in the cavity and opening a first guide groove on the upper and lower surfaces of the pressing rod, when the ball is rolled on the first and second guide grooves, the friction force of the pressing rod moving left and right in the cavity is reduced when the pressing rod moves left and right in the cavity.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1-5 This utility model provides two technical solutions: a hatch pressing mechanism, including a hatch frame 1;

[0024] The door frame 1 is fixed to the surface of the sealed door 3 by a hinge block 2. A locking block 4 is fixed to the outside of the door frame 1. A through hole is opened inside the locking block 4. A base plate 5 is fixed to the outside of the sealed door 3. An integral cavity shell 6 is provided on the outside of the base plate 5. A pressing rod 7 is movably provided inside the cavity shell 6. An integral locking rod 8 is provided at the end of the pressing rod 7. The outer surface of the locking rod 8 is inserted into the through hole of the locking block 4.

[0025] By fixing the inner wall of the hinge block 2 to the surfaces of the door frame 1 and the sealing door 3, the opening and closing of the door frame 1 and the sealing door 3 can be realized. A locking block 4 is fixed on the surface of the door frame 1. A pressing rod 7 is movably set in the outer cavity shell 6 of the base plate 5, and an integral locking rod 8 is set at the end of the pressing rod 7. When the pressing rod 7 is pushed to the left and moves in the cavity shell 6 of the base plate 5, the surface of the locking rod 8 is inserted into the through hole of the locking block 4, thus realizing the sealing and locking between the door frame 1 and the sealing door 3.

[0026] Example 2

[0027] See attached document Figures 1 to 5 Based on Embodiment 1, in order to achieve a sealed lock between the door frame 1 and the sealing door 3, the upper and lower surfaces of the cavity shell 6 are provided with an integrally formed first shaft pin 10. The outer part of the first shaft pin 10 is sleeved in the bottom through hole of the adjusting plate 13. The through holes are set in two sets, and the two sets of through holes are symmetrical about the central axis of the adjusting plate 13. The second rotating pin 14 is sleeved in the through hole of the adjusting plate 13. The bottom end of the second rotating pin 14 is integrally formed on the outer surface of the handle 15. The upper and lower surfaces of the handle 15 are provided with through holes. The surface of the fixed rotating rod 11 is sleeved in the through hole of the handle 15. The surface of the fixed rotating rod 11 is fixed in the extrusion rod 7. The upper and lower surfaces of the extrusion rod 7 are provided with a first guide groove 9, and the first guide groove 9 and the second guide groove 12 are correspondingly arranged. The second guide groove 12 is opened in the cavity shell 6. Ball bearings 16 are rolled in the first guide groove 9 and the second guide groove 12.

[0028] In actual use, by sleeved the outer part of the second pivot pin 14 inside the adjusting plate 13, when the handle 15 is pressed to rotate it along the central axis of the second pivot pin 14, the adjusting plate 13 rotates along the central axis of the first pivot pin 10. Therefore, the handle 15 pushes the pressing rod 7 to the left in the cavity shell 6, so that the outer part of the locking rod 8 is inserted into the through hole of the locking block 4, thus achieving a sealing lock between the door frame 1 and the sealing door 3. Conversely, when the handle 15 is lifted, the pressing rod 7 moves to the right in the cavity shell 6, so that the locking rod 8 disengages from the through hole of the locking block 4, thus enabling the opening and closing between the door frame 1 and the sealing door 3. By opening the second guide groove 12 in the cavity shell 6 and the first guide groove 9 on the upper and lower surfaces of the pressing rod 7, when the ball bearing 16 is rolled on the first guide groove 9 and the second guide groove 12, the friction of the pressing rod 7 moving left and right in the cavity shell 6 is reduced.

[0029] 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.
