A steel door internal buffer device

Abstract

This invention discloses an internal buffer device for a steel door, comprising a support base, a hinge base, a hinge block, and a buffer rod. The hinge base is mounted on the outer wall of the support base, and two sets of support blocks are mounted on the outer wall of the support base, with the support blocks located on one side of the hinge base. This invention uses the hinge blocks and hinge base to fix the angle of the steel door. After the door leaf rotates to the top of the buffer rod, the door leaf applies pressure to the top of the hinge block, causing the hinge block to move. This movement of the hinge block moves a first circular hole. After the first circular hole aligns with a second circular hole, a stop pin is inserted into the interior of the first and second circular holes, thereby achieving the purpose of locking the opening angle of the steel door.

Description

Technical Field

[0001] This invention relates to the field of ship steel door equipment technology, specifically to an internal buffer device for a steel door. Background Technology

[0002] With the development of the shipbuilding industry, customers are increasingly demanding higher safety standards for ship outfitting equipment. Ship steel doors are closing devices for the entrances and exits of ship cabins. Steel doors can be opened and closed in various ways, such as hinged doors and sliding doors. In the existing technology, when a hinged door moves, a stop pin is inserted into the round hole on the hinge seat and hinge block, thereby locking the opening angle of the steel door.

[0003] The existing internal buffer devices for steel doors have the following defects:

[0004] Patent document CN212984997U discloses a steel door for home use with a two-way opening structure. The protected claim "includes a device body and a fixed handle. A left door is located inside the left side of the device body, and a right door is located inside the right side of the device body. A fixed base is located inside the device body, and a buffer groove is formed inside the fixed base. A buffer spring is fixedly installed inside the buffer groove. A fixed compartment is formed inside the right door, and a support spring is fixedly installed inside the fixed compartment. A slider is fixedly installed on the outer wall of the support spring. A sliding groove is formed inside the device body. This invention, by setting a buffer rod and a fixed base, allows the buffer rod to be stored in the buffer groove inside the fixed base when the left and right doors are pushed or pulled. Then, the buffer spring cushions the impact when the buffer rod contacts the slider, preventing the left and right doors from colliding with the device body, thus reducing wear and noise." However, this device cannot lock the opening angle of the steel door, making it inconvenient to fix the door angle. Summary of the Invention

[0005] The purpose of this invention is to provide an internal buffer device for steel doors to solve the problem mentioned in the background art of not being able to fix the angle of steel doors.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel door internal buffer device, comprising a support base, a hinge base, a hinge block and a buffer rod, wherein the outer wall of the support base is fitted with a hinge base;

[0007] A hinge block is installed on the outer wall of the hinge seat. The outer wall of the hinge block is provided with multiple sets of No. 1 circular holes. A hinge pin is installed through the inner wall of the hinge seat, and both ends of the hinge pin penetrate through the inner wall of the hinge block.

[0008] Two sets of support blocks are installed on the outer wall of the support base, and the support blocks are located on one side of the hinge base.

[0009] Preferably, the outer wall of the hinge seat is provided with a second circular hole, and the second circular hole is located on one side of the hinge block.

[0010] Preferably, a support shaft is installed through the inner wall of the support block, and a support plate is installed at one end of the support shaft.

[0011] Preferably, a fixing block is installed through the inner wall of the support plate, and a buffer rod is installed through the inner wall of the fixing block.

[0012] Preferably, the inner wall of the support block is equipped with two sets of plates, and the plates are located on one side of the support shaft. A rotating shaft is installed through the inner wall of the plates. A first gear is installed around the outer wall of the rotating shaft, and a second gear is installed around the outer wall of the support shaft. A first drive gear is installed at one end of the rotating shaft. The outer wall of the rotating shaft is provided with multiple sets of limiting grooves, and the limiting grooves are located on one side of the second gear.

[0013] Preferably, a drive motor is installed on the inner wall of the support block, and the drive motor is located on one side of the plate. A second drive gear is installed at the output end of the drive motor, and the second drive gear meshes with the first drive gear.

[0014] Preferably, the inner wall of the support block is equipped with two sets of telescopic rods, and the telescopic rods are located on one side of the support shaft, with a positioning block installed at the top of the telescopic rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses a hinge block and a hinge seat to fix the angle of a steel door. After the door leaf rotates to the top of the buffer rod, the hinge block moves when the door leaf rotates and applies pressure to the top of the hinge block. The movement of the hinge block causes the first round hole to move. After the first round hole and the second round hole are aligned, the stop pin is inserted into the inside of the first round hole and the second round hole, thereby achieving the purpose of locking the opening angle of the steel door.

[0017] 2. This invention adjusts the buffering force borne by the buffer rod by installing a support block and a buffer rod. The top of the telescopic rod retracts, causing the positioning block to move. After the positioning block moves out of the limiting groove, it no longer limits the support shaft. The output end of the drive motor rotates, causing the second drive gear to rotate. The second drive gear rotates, causing the rotating shaft to rotate. When the rotating shaft rotates, it drives the first gear to rotate. When the first gear rotates, it drives the support shaft to rotate. The rotation of the support shaft causes the support plate to move. The movement of the support plate causes the buffer rod to move. After the buffer rod is moved to the predetermined position, the top of the telescopic rod extends, causing the positioning block to enter the limiting groove and limit the support shaft, thus achieving the purpose of adjusting the buffering force borne by the buffer rod.

[0026] Example 1: Please refer to Figure 1 A steel door internal buffer device includes a support base 1, a hinge base 101, a hinge block 2, and a buffer rod 4. The hinge base 101 is mounted on the outer wall of the support base 1, providing support for the hinge base 101. Two sets of support blocks 5 are mounted on the outer wall of the support base 1, with the support blocks 5 located on one side of the hinge base 101. The support base 1 provides support for the support blocks 5. A second circular hole 102 is provided on the outer wall of the hinge base 101, located on one side of the hinge block 2. The hinge base 101 provides installation space for the second circular hole 102. A support shaft 501 is installed through the inner wall of the support block 5, providing installation space for the support shaft 501. A support plate 3 is mounted on one end of the support shaft 501. The support shaft 501 provides support for the door. Plate 3 provides support. A fixing block 401 is installed through the inner wall of the support plate 3, providing installation space for the fixing block 401. A buffer rod 4 is installed through the inner wall of the fixing block 401, providing installation space for the buffer rod 4. A drive motor 6 is installed on the inner wall of the support block 5, and the drive motor 6 is located on one side of the plate 503. The support block 5 provides installation space for the drive motor 6. A second drive gear 601 is installed at the output end of the drive motor 6, and the second drive gear 601 meshes with the first drive gear 505. Two sets of telescopic rods 7 are installed on the inner wall of the support block 5, and the telescopic rods 7 are located on one side of the support shaft 501. A positioning block 701 is installed at the top of the telescopic rod 7, and the telescopic rod 7 provides support for the positioning block 701.

[0027] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 A hinge block 2 is installed on the outer wall of the hinge base 101. The outer wall of the hinge block 2 is provided with multiple sets of first round holes 201. A hinge pin 301 is installed through the inner wall of the hinge base 101, and both ends of the hinge pin 301 pass through the inner wall of the hinge block 2. After the door leaf rotates to the top of the buffer rod 4, the hinge block 2 moves when the door leaf rotates and applies pressure to the top of the hinge block 2. The movement of the hinge block 2 drives the first round hole 201 to move. After the first round hole 201 is aligned with the second round hole 102, the stop pin is inserted into the interior of the first round hole 201 and the second round hole 102, thereby achieving the purpose of locking the opening angle of the steel door.

[0028] Example 3: Please refer to 1 and Figure 4Two sets of plates 503 are installed on the inner wall of the support block 5, and the plates 503 are located on one side of the support shaft 501. A rotating shaft 504 is installed through the inner wall of the plates 503. A first gear 506 is installed around the outer wall of the rotating shaft 504, and a second gear 502 is installed around the outer wall of the support shaft 501. A first drive gear 505 is installed at one end of the rotating shaft 504. The outer wall of the rotating shaft 504 is provided with multiple sets of limiting grooves 507, and the limiting grooves 507 are located on one side of the second gear 502. When adjusting the buffering force borne by the buffer rod 4, the top of the telescopic rod 7 retracts, causing the positioning block 701 to move. After the positioning block 701 moves out of the interior of the limiting groove 507, The positioning block 701 no longer limits the support shaft 501. The output end of the drive motor 6 rotates, causing the second drive gear 601 to rotate. The rotation of the second drive gear 601 drives the rotating shaft 504 to rotate. When the rotating shaft 504 rotates, it drives the first gear 506 to rotate. When the first gear 506 rotates, it drives the support shaft 501 to rotate. The rotation of the support shaft 501 drives the support plate 3 to move. The movement of the support plate 3 drives the buffer rod 4 to move. After the buffer rod 4 is moved to the predetermined position, the top of the telescopic rod 7 extends, causing the positioning block 701 to enter the interior of the limiting groove 507 to limit the support shaft 501, thereby adjusting the buffering force borne by the buffer rod 4.

[0029] Working principle: First, after the door leaf rotates to the top of the buffer rod 4, the door leaf applies pressure to the top of the hinge block 2 as it rotates, causing the hinge block 2 to move. The movement of the hinge block 2 drives the first circular hole 201 to move. After the first circular hole 201 aligns with the second circular hole 102, the stop pin is inserted into the interior of the first circular hole 201 and the second circular hole 102, thereby achieving the purpose of locking the opening angle of the steel door. When adjusting the buffering force borne by the buffer rod 4, the top of the telescopic rod 7 retracts, causing the positioning block 701 to move. After the positioning block 701 moves out of the interior of the limiting groove 507, the positioning block 701 no longer has a limiting effect on the support shaft 501. The output end of the drive motor 6 rotates, causing the second drive gear 601 to rotate. The rotation of the second drive gear 601 drives the rotating shaft 504 to rotate. When the rotating shaft 504 rotates, it drives the first gear 506 to rotate. When the first gear 506 rotates, it drives the support shaft 501 to rotate. The rotation of the support shaft 501 drives the support plate 3 to move. The movement of the support plate 3 drives the buffer rod 4 to move. After the buffer rod 4 is moved to the predetermined position, the top end of the telescopic rod 7 extends, causing the positioning block 701 to enter the interior of the limiting groove 507 to limit the support shaft 501, thereby achieving the purpose of adjusting the buffering force borne by the buffer rod 4.
