Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, specifically a fixed support device for fireproof doors of tobacco storage rooms. Background Technology

[0002] In the safety management of tobacco processing enterprises, fire protection standards (such as GB 50016-2014) clearly require that fire doors at safety exits in Class C workshops must be kept closed to effectively prevent the spread of fire in the event of a fire. However, forklift logistics operations in tobacco storage rooms require frequent passage through safety exits, forcing fire doors to be repeatedly opened and closed, creating a prominent contradiction between fire safety compliance and production efficiency.

[0003] The current operating method of relying on two workers to manually operate fire doors has significant drawbacks: manual operation is insufficient to withstand the airflow or vibration from forklift passage, causing door displacement or even accidental closure. This not only hinders material transport but also compromises the fire door's seal, creating a fire hazard. Furthermore, each forklift passage requires manual readjustment of the door position, severely reducing logistics efficiency, and sudden external forces can easily lead to loss of control, increasing the risk of collisions. Existing technology does not yet provide a dedicated device that simultaneously satisfies both rigid fixation in the open state and rapid retraction to restore a seal.

[0004] Therefore, this application proposes a fireproof door fixing support device for tobacco storage rooms, which can realize the rigid fixing and quick storage of fireproof doors operated by a single person, ensuring both the impact resistance stability in the open state and the normal closed sealing state after storage. Utility Model Content

[0005] The main objective of this application is to provide a fixed support device for fireproof doors in tobacco storage rooms, which aims to solve the technical problem that there is no dedicated device in the existing technology field that can simultaneously satisfy rigid fixation in the open state and rapid storage and restoration of sealing.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A fireproof door fixing support device for a tobacco storage room includes: a left fixing plate and a right fixing plate;

[0008] The outer wall of the right fixing plate is provided with a base, and the outer wall of the base is provided with a through hole;

[0009] A support rod is rotatably connected to the outer wall of the left fixed plate via a rotating device. A top plate is provided at the top of the outer wall of the support rod. A first slider is slidably connected to the outer wall of the support rod. A connecting rod is provided on the outer wall of the first slider via a connecting seat. A first elongated hole communicating with the inner cavity is opened on both the upper and lower sides of the outer wall of the connecting rod. A fixed seat is slidably connected to the outer wall of the connecting rod. A cylinder is provided on the right end wall of the connecting rod. A baffle is interference-fitted to the outer wall of the cylinder. A second elongated hole communicating with the inner cavity is opened on both the upper and lower sides of the outer wall of the cylinder. A circular block is movably inserted into the connecting rod. A second slider is provided on the outer wall of the circular block, and the outer end of the second slider extends out of the first elongated hole. A long rod is provided on the right side wall of the circular block, and the right end of the long rod extends out of the cylinder and is provided with a socket.

[0010] As a further improvement of this application, the rotating device is a bearing structure, including a bearing seat fixed to the left fixed plate, and a bearing with an inner ring that is interference-fitted with the support rod.

[0011] As a further improvement of this application, the outer wall of the cylinder is provided with threads.

[0012] As a further improvement of this application, the fixing seat and the outer wall of the cylinder are connected by a threaded connection.

[0013] As a further improvement of this application, the first elongated hole is connected to the second elongated hole.

[0014] The technical solution provided in this application may include the following beneficial effects:

[0015] This application utilizes the synergistic effect of a retractable support rod structure (connecting rod and long rod) and a rotating device to enable a single person to quickly complete the opening, fixing, and storage operations of fire doors. The socket and insertion locking mechanism, combined with the threaded locking of the fixing seat and cylinder, forms a double impact-resistant fixation, ensuring door stability when forklifts pass. Furthermore, the mechanical limiting design of the second slider sliding into the second long strip hole and then abutting against the baffle effectively prevents the support from loosening. When the device is stored, the long rod is completely retracted into the connecting rod, fitting snugly against the surface of the fire door without affecting its sealing performance and fire safety compliance in the normally closed state. The welding / bolt installation method of the left and right fixing plates and the adjustable height of the support rod adapt to different specifications of fire doors, significantly improving the device's versatility and safety reliability.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-2 As shown, a fireproof door fixing support device for a tobacco storage room includes a left fixing plate 1 and a right fixing plate 2. A base 3 is provided on the outer wall of the right fixing plate 2, and an insertion hole 4 is provided through the outer wall of the base 3. A support rod 6 is rotatably connected to the outer wall of the left fixing plate 1 via a rotating device 5. A top plate 7 is provided at the top of the outer wall of the support rod 6. A slider 8 is slidably connected to the outer wall of the support rod 6. A connecting rod 10 is provided on the outer wall of the slider 8 via a connecting seat 9. A first elongated hole 11 communicating with the inner cavity is provided on both the upper and lower sides of the outer wall of the connecting rod 10. The connecting rod 10 slides... A fixed base 12 is connected to the connecting rod 10. A cylinder 13 is provided on the right end wall of the connecting rod 10. The outer wall of the cylinder 13 is threaded. A baffle 14 is interference-fitted to the outer wall of the cylinder 13. The upper and lower sides of the outer wall of the cylinder 13 are provided with second elongated holes 15 communicating with the inner cavity. A circular block 16 is movably inserted into the connecting rod 10. A second slider 17 is provided on the outer wall of the circular block 16, and the outer end of the second slider 17 extends out of the first elongated hole 11. A long rod 18 is provided on the right side wall of the circular block 16, and the right end of the long rod 18 extends out of the cylinder 13 and is provided with a socket 19. Through the rotational insertion of the telescopic support rod and the double mechanical locking, the displacement or accidental closure of the fire door is effectively prevented when the forklift passes through, while ensuring the normal sealing after storage.

[0023] Furthermore, the rotating device 5 includes a bearing housing and a bearing. The bearing housing is fixedly connected to the outer wall of the left fixed plate 1, and the outer ring of the bearing is fixedly connected to the inner wall of the bearing housing. The inner ring of the bearing is interference-fitted with the outer wall of the support rod 6. The position of the first elongated hole 11 can be adjusted by rotating the rotating device 5 so that the socket 19 and the socket 4 are vertically aligned. Then, the first elongated hole 11 is lowered, and the socket 19 is inserted into the socket 4. This device supports the two fire doors, and the forklift is used to transport goods.

[0024] Furthermore, the fixing seat 12 is threadedly connected to the outer wall of the cylinder 13. Pulling the socket 19 to the right causes the socket 19 to move the long rod 18, the second slider 17 and the round block 16 to the right within the connecting rod 10 until the second slider 17 moves into the second elongated hole 15 and abuts against the left side wall of the baffle 14, thus tightening the fixing seat 12 onto the left side wall of the cylinder 13. The long support rod is then assembled through the first elongated hole 11 and the long rod 18.

[0025] Furthermore, the first elongated hole 11 is connected to the second elongated hole 15. Pulling the socket 19 to the right causes the socket 19 to move the long rod 18, the second slider 17 and the round block 16 to the right within the connecting rod 10 until the second slider 17 moves into the second elongated hole 15 and abuts against the left side wall of the baffle 14, facilitating the movement of the second slider 17 on the outer wall of the connecting rod 10 and the cylinder 13.

[0026] The detailed connection methods are well-known technologies in the field. All components in this solution are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0027] One specific application of this embodiment is:

[0028] In use, the left fixing plate 1 and the right fixing plate 2 are installed on the two fire doors by welding or bolting. The fire doors are opened, and the socket 19 is pulled to the right. This causes the socket 19 to move the long rod 18, the second slider 17, and the round block 16 to the right within the connecting rod 10 until the second slider 17 moves into the second elongated hole 15 and abuts against the left side wall of the baffle 14. The fixing seat 12 is then screwed onto the left side wall of the cylinder 13. The fixing seat 12 and the baffle 14 fix the second slider 17, thereby fixing the long rod 18 into the first elongated hole 11. The first elongated hole 11 and the long rod 18 are assembled into a long support rod. Pushing the first elongated hole 11 upwards causes the first elongated hole 11 to move the long rod 18, the socket 19, the long rod 18, the second slider 17, and the round block 16 to the right within the connecting rod 10. The structure, including seat 19, connecting seat 9, and slider 8, moves upward on the outer wall of support rod 6. The position of the first elongated hole 11 is adjusted by rotation via rotating device 5. After the socket 19 and the socket 4 are aligned vertically, the first elongated hole 11 is lowered, and the socket 19 is inserted into the socket 4. This device supports the two fire doors, allowing forklifts to transport goods. When the fire door needs to be closed, the first elongated hole 11 is pushed upward, and the socket 19 is moved out of the socket 4. The fixing seat 12 is unscrewed from the outer wall of cylinder 13, and the long rod 18 is pushed to the left to retract into the first elongated hole 11, shortening the length of the first elongated hole 11 and the long rod 18. The first elongated hole 11 is then fitted onto the fire door, and the fire door is closed.

[0029] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
