Description

Technical Field

[0002] With the development of the times, the iron doors used in daily life have not only made great breakthroughs in quality, but also have hundreds of colors to choose from on the surface. The iron gate has a beautiful appearance. Its initial function is to prevent theft, and now its functions are gradually diversified. The iron doors used in the home are mostly used outside the house to protect the personal safety of residents and better protect the personal safety of residents from malicious damage. The door axis is a connecting device used to install the door leaf and the door frame to facilitate the free opening of the door leaf. It mainly consists of the upper door leaf axis, the lower door leaf axis, the frame axis and the base. The upper door leaf axis, the lower door leaf axis and the rear end of the frame axis body are provided with a fixing block.

[0003] The existing ones are of ordinary structure, single functionality and only have basic connection functions. Not only do they require operators to perform cumbersome disassembly and assembly procedures during installation, but they also cannot realize the automatic opening or closing function of the power supply during subsequent use.

[0004] Although sensors can be used to monitor the power on and off, and send out instructions to turn the power on or off after sensing that the door shaft is installed in place, the sensor itself is easily disturbed by vibration, dust, etc., and has many sensing failures and is prone to lag. In addition, when installing the sensor, due to the existence of programming codes, the complexity of the door shaft structure and the difficulty of subsequent maintenance will also increase.

[0005] For this reason, it is necessary for us to design a wiring door shaft. Summary of the invention

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] refer to Figures 1 to 8 , a wiring door shaft, comprising:

[0041] The mounting base 1 is arranged in a horizontal state, and positioning flanges 3 are formed on both sides of the mounting base 1;

[0042] The bearing shell 4 is arranged at the upper end of the mounting base 1, and the electronic components of the wiring door shaft can be installed inside the bearing shell 4;

[0043] Two electrode springs 6 are symmetrically arranged inside the bearing housing 4 and can connect and disconnect the power supply when the wiring door shaft is installed;

[0044] Two return springs 7 are symmetrically arranged at the lower end of the bearing housing 4, the upper ends of the two return springs 7 are respectively connected to the bearing housing 4, and the lower ends are respectively connected to the mounting base 1;

[0045] Three powerful electromagnets 8 are arranged in a triangular shape at the upper end of the bearing housing 4 and are connected to the power supply through wires;

[0046] The linkage pressing mechanism 9 is arranged on one side of the bearing shell 4 close to the two electrode springs 6. The linkage pressing mechanism 9 can drive the two electrode springs 6 to move in the vertical direction during installation;

[0047] Two positioning clamping mechanisms 17 are respectively arranged on both sides of the carrying shell 4. The two positioning clamping mechanisms 17 can make the carrying shell 4 stay briefly when moving;

[0048] The driving mechanism 26 is arranged at one end of the bearing housing 4 away from the electrode spring 6, and the driving mechanism 26 comprises a curved driving support rod 31, and the middle part of the driving support rod 31 is hinged to a support fixedly connected to the mounting base 1;

[0049] The quick-connect mechanism 35 includes a connecting pin 36 and a positioning sleeve 44. The connecting pin 36 is vertically arranged and its upper end is fixedly connected to the bearing shell 4. The connecting pin 36 is slidably connected to the mounting base 1. The positioning sleeve 44 is coaxially arranged with the connecting pin 36.

[0050] Before the device is operated, the operator should first preset the positioning sleeve 44, that is, pre-install the positioning sleeve 44 on the door frame through bolts, and then the operator pushes the driving support rod 31 upward. Since the driving support rod 31 is curved and the middle part is hinged to the support fixedly connected to the mounting base 1, the driving support rod 31 will rotate around the hinge point at this time, and then the rotation of the driving support rod 31 will push the supporting shell 4 to move downward (the specific movement process will be explained later), and the downward movement of the supporting shell 4 will push the connecting pin 36 to move downward, and after the supporting shell 4 moves downward, it will stop for the first time under the action of the two positioning clamping mechanisms 17. At the same time, the downward movement of the supporting shell 4 will also press the two electrode springs 6 downward through the linkage pressing mechanism 9, and at this time, the upper ends of the two electrode springs 6 move downward to the inside of the supporting shell 4. After the above work is completed, the operator operates the connecting pin 36 to complete the quick installation with the positioning sleeve 44 (the specific quick disassembly process is explained in the working principle part), and then assembles the installation base 1 and the door frame in place through the gasket. In this process, the two positioning flanges 3 will be initially positioned with the door frame, and because the two electrode springs 6 are pressed downward, the two electrode springs 6 and the door frame are not squeezed at this time, that is, the power supply is automatically disconnected. When the connecting pin 36 and the positioning sleeve 44 are assembled, and the operator completes the debugging and confirms that the two will not be separated, the operator continues to push the driving support rod 31. At this time, the bearing shell 4 will first move downward for a short distance under the action of the two positioning clamping mechanisms 17, and then move upward to reset. The force required for this reset process is realized by the two reset springs 7. As can be seen from the above, the two electrode springs 6 will also reset upward at this time, and because the two reset electrode springs 6 will be squeezed with the door frame, the electrode springs 6 complete the overlap with the door body cast steel parts, and the power supply is automatically connected. The power supply is turned on and the three powerful electromagnets 8 are energized and fixedly connected with the mounting holes of the door frame, thereby realizing the installation of the entire device.

[0051] In order to prevent the driving support rod 31 from being unable to drive the bearing housing 4 to move, the following features are specifically provided:

[0052] The driving mechanism 26 further comprises a driving roller 32, a rubber gasket 33 and a driving arc block 34. The driving arc block 34 is fixedly connected to one end of the bearing shell 4 near the driving support rod 31, the driving roller 32 is rotatably connected to one end of the driving support rod 31 near the driving arc block 34, and the rubber gasket 33 is sleeved on the outside of the driving roller 32. When the driving support rod 31 rotates, the rotation of the driving support rod 31 will drive the driving roller 32 connected thereto to move. When the driving roller 32 moves, the driving arc block 34 will interfere with the driving arc block 34 through the rubber gasket 33. At this time, as the driving roller 32 moves in an arc shape in the vertical direction, the driving arc block 34 will drive the bearing shell 4 to move in a straight line in the vertical direction. In this process, the rubber gasket 33 can ensure that the driving roller 32 always conflicts with the driving arc block 34, so as to prevent the two from being separated and unable to drive the bearing shell 4 to move.

[0053] In order to avoid prematurely triggering the second stage displacement of the bearing housing 4, the following features are specifically provided:

[0054] The driving mechanism 26 also includes a positioning slider 30, two positioning supports 27, two positioning long pins 28 and two positioning springs 29. The two positioning supports 27 are symmetrically arranged at the end of the driving support rod 31 away from the bearing shell 4. The two ends of the two positioning long pins 28 are respectively connected to the two positioning supports 27. The two positioning springs 29 are respectively sleeved on the outside of the two positioning long pins 28. The positioning slider 30 is slidably connected to the two positioning long pins 28 at the same time. One end of the positioning spring 29 is fixedly connected to the positioning support 27, and the other end is fixedly connected to the positioning slider 30. When the driving support rod 31 rotates, the bearing shell 4 is retained and displaced in two stages when it is at the lowest point due to the positioning clamping mechanism 17. Therefore, the positioning slider 30 can ensure that the end of the driving support rod 31 away from the bearing shell 4 will not continue to move upward when it is at the highest point, so as to avoid triggering the two-stage displacement of the bearing shell 4 in advance. When it is necessary to drive the stationary bearing shell 4 to continue to move downward, thereby triggering the second stage displacement of the bearing shell 4 upward, the operator should first move the positioning slider 30 to move and avoid, and then push the driving support rod 31 to trigger the second stage displacement of the bearing shell 4. In this process, the two positioning springs 29 can ensure that the positioning slider 30 can move to the original position after avoiding, and the specific process of the stationary and second stage displacement of the bearing shell 4 is explained later.

[0055] In order to press the electrode spring 6 so that it does not trigger the power supply when it contacts the door frame, the following features are specifically set:

[0056] The linkage pressing mechanism 9 includes two positioning racks 10, two transfer gears 11, two downward moving racks 12 and two limiting slide rails 13. Two movable through holes 5 are formed on the side wall of the bearing shell 4. One end of the two electrode springs 6 extends out of the two movable through holes 5 respectively. The two positioning racks 10 are symmetrically arranged at the end of the bearing shell 4 away from the positioning slider 30. The two positioning racks 10 are fixedly connected to the mounting base 1 through a bracket. The two transfer gears 11 are respectively arranged above the two positioning racks 10 and are rotatably connected to the side wall of the bearing shell 4 through a pin. The transfer gears 11 can also be respectively engaged with the two positioning racks 10, the two downward racks 12 are respectively arranged on the side of the two transfer gears 11 away from the two positioning racks 10, the two downward racks 12 are respectively engaged with the two transfer gears 11, the two limiting slide rails 13 are respectively slidably connected with the two downward racks 12, and the two limiting slide rails 13 are respectively fixedly connected to the side walls of the bearing shell 4, the two snap-on baffles 14 are respectively fixedly connected with the two downward racks 12, and the two snap-on baffles 14 are respectively abutted against the upper side of one end of the two electrode springs 6 passing through the movable through hole 5. When the carrying shell 4 moves downward, the movement of the carrying shell 4 will drive the two transfer gears 11 connected thereto to move downward. When the two transfer gears 11 mesh with the two positioning racks 10 and rotate, the rotation of the two transfer gears 11 will drive the meshing downward moving rack 12 will drive the connected downward moving rack 12 to move downward. The downward movement of the connected rack 12 will drive the connected snap-in baffle 14 to move downward. The downward movement of the two snap-in baffles 14 will drive the two electrode springs 6 that are against each other to move downward at one end extending out of the movable through hole 5. At this time, the two electrode springs 6 are pressed downward and will not trigger the power supply when they come into contact with the door frame.

[0057] In order to prevent the bearing housing 4 from moving during the movement, the following features are specifically provided:

[0058] The linkage pressing mechanism 9 also includes two limit stop bars 16, and the positioning clamping mechanism 17 includes two limit support seats 24 and two limit pins 25. The two clamping baffles 14 are formed with a limit flange 15 on one side away from the downwardly moving rack 12. The two limit stop bars 16 are respectively fixedly arranged on the side of the two clamping baffles 14 away from the downwardly moving rack 12 and are fixedly connected to the bearing shell 4. The two limit stop bars 16 are respectively slidably connected to the limit flanges 15. A total of four limit supports 24 are respectively fixedly connected to both sides of the bearing shell 4. The four limit pins 25 are respectively slidably connected to the four limit supports 24 and their lower ends are respectively fixedly connected to the mounting base 1. When the bearing shell 4 moves, the two limit stop bars 16 can provide limits for the two clamping baffles 14 respectively, and the four limit pins 25 can cooperate with the four limit supports 24 to limit the movement of the bearing shell 4 to prevent the bearing shell 4 from moving during the movement.

[0059] In order to achieve the residence and secondary displacement of the bearing housing 4, the following features are specifically set:

[0060] The positioning clamping mechanism 17 also includes a positioning chuck 18, a limiting clamping plate 21, a sliding pin 22 and a limiting support rod 23. Two limiting through holes 2 are also formed on the mounting base 1. A first limiting groove 19 and a second limiting groove 20 are formed on the positioning chuck 18. The limiting clamping plate 21 is slidingly connected to the first limiting groove 19. The sliding pin 22 is rotationally connected to the limiting clamping plate 21 and is slidingly connected to the side wall of the second limiting groove 20. The upper end of the limiting support rod 23 is rotationally connected to the sliding pin 22, and the lower end is rotationally connected to the side wall of the limiting through hole 2 through a short pin. During the movement of the bearing shell 4, the limiting card plate 21 will be slidably connected with the first limiting groove 19, and the limiting card plate 21 can ensure that the positioning chuck 18 will not be separated from the sliding pin 22 during the movement. Then, in the first displacement stage, when the positioning chuck 18 moves downward to drive the bearing shell 4 to move to the stationary position, the sliding pin 22 will move along the side wall of one side of the second limiting groove 20. When the sliding pin 22 moves to the highest point of the second limiting groove 20, it will stay. At this time, the limiting support rod 23 plays a role of pulling and positioning. When the bearing shell 4 performs a secondary displacement, the positioning chuck 18 moves downward first. At this time, the sliding pin 22 drives the limiting card plate 21 to move along the side wall of the other side of the second limiting groove 20. Then, after the positioning chuck 18 loses the pulling effect of the limiting support rod 23, the bearing shell 4 will move upward under the action of the two reset springs 7. This process is the secondary displacement process of the bearing shell 4.

[0061] In order to reduce the difficulty of installing the connecting pin 36 and the positioning sleeve 44, the following features are specifically set:

[0062] The quick-connect mechanism 35 also includes a connecting tension spring 37, a positioning transfer shaft 38, a connecting sleeve 42 and four positioning steel balls 41. The connecting sleeve 42 is slidably arranged coaxially with the connecting pin 36. The connecting sleeve 42 is also fixedly connected to the mounting base 1. The connecting tension spring 37 is sleeved on the outside of the connecting pin 36. The upper end of the connecting tension spring 37 is connected to the inner wall of the connecting sleeve 42, and the lower end is connected to the connecting pin 36. The positioning transfer shaft 38 is connected to the lower end of the connecting pin 36. The four positioning steel balls 41 are evenly arranged in an array along the circumferential direction of the positioning transfer shaft 38. When installing the connecting pin 36 and the positioning sleeve 44, the operator first presses the connecting pin 36 downward. At this time, the downward movement of the connecting pin 36 will drive the positioning transfer shaft 38 connected to it to move downward. At this time, the connecting tension spring 37 is stretched, and the four positioning steel balls 41 move upward to prepare for the subsequent clamping work. The specific clamping process will be explained later. The four positioning steel balls 41 can reduce the difficulty of installation and positioning and improve work efficiency.

[0063] In order to ensure that the connecting pin 36 will not be separated from the positioning sleeve 44, the following features are specifically provided:

[0064] A first conical surface 39 and a second conical surface 40 are formed on the positioning adapter shaft 38, four positioning through holes 43 are formed on the side wall of the connecting sleeve 42, and an annular groove 45 is formed on the inner wall of the positioning sleeve 44. The cone angle of the first conical surface 39 is smaller than the cone angle of the second conical surface 40, and four positioning steel balls 41 are movably arranged between the first conical surface 39 and the second conical surface 40 respectively. The four positioning steel balls 41 are coaxially arranged with the four positioning through holes 43 respectively and can be offset against the annular groove 45. When the connecting pin 36 and the positioning sleeve 44 are quickly installed, as can be seen from the previous text, the four positioning steel balls 41 move upward at this time, and one end of the four positioning steel balls 41 respectively extends outward corresponding to the four positioning through holes 43. After the connecting pin 36 moves to the inside of the positioning sleeve 44, the four outwardly extending positioning steel balls 41 can respectively abut against the annular grooves 45. Then the operator drives the support rod 31 with a wave, and after the bearing shell 4 moves upward, the second cone surface 40 moves upward to squeeze the four positioning steel balls 41, ensuring that the four positioning steel balls 41 can be pressed against the annular grooves 45, so that the connecting pin 36 will not be separated from the positioning sleeve 44.

[0065] The working principle of this device is: before the device is operated, the operator should preset the positioning sleeve 44, that is, pre-install the positioning sleeve 44 on the door frame through bolts, and then the operator pushes the driving support rod 31 upward. Since the driving support rod 31 is curved in shape and the middle part is hinged to the support fixedly connected to the mounting base 1, the driving support rod 31 will rotate around the hinge point at this time, and then the rotation of the driving support rod 31 will push the bearing shell 4 to move downward, and the downward movement of the bearing shell 4 will push the connecting pin 36 to move downward.

[0066] When the bearing shell 4 moves downward, the limiting card plate 21 will be slidably connected with the first limiting groove 19, and the limiting card plate 21 can ensure that the positioning chuck 18 will not be separated from the sliding pin 22 during the movement. Then, in the first displacement stage, when the positioning chuck 18 moves downward to drive the bearing shell 4 to move to the stationary position, the sliding pin 22 will move along the side wall of one side of the second limiting groove 20. When the sliding pin 22 moves to the highest point of the second limiting groove 20, it will stay. At this time, the limiting support rod 23 plays a role of pulling and positioning. When the bearing shell 4 performs a secondary displacement, the positioning chuck 18 moves downward first. At this time, the sliding pin 22 drives the limiting card plate 21 to move along the side wall of the other side of the second limiting groove 20. Then, after the positioning chuck 18 loses the pulling effect of the limiting support rod 23, the bearing shell 4 will move upward under the action of the two reset springs 7. This process is the secondary displacement process of the bearing shell 4.

[0067] At the same time, the downward movement of the carrying shell 4 will also press the two electrode springs 6 downward through the clamping baffle 14 , and at this time, the upper ends of the two electrode springs 6 move downward to the inside of the carrying shell 4 .

[0068] When the above work is completed, the operator operates the connecting pin 36 to complete the quick installation through the four positioning steel balls 41 and the positioning sleeve 44. During this process, the two positioning flanges 3 will be initially positioned with the door frame, and because the two electrode springs 6 are pressed downward, the two electrode springs 6 are not squeezed with the door frame at this time, that is, the power is automatically disconnected.

[0069] When the connecting pin 36 and the positioning sleeve 44 are assembled, and the operator completes the debugging and confirms that the two will not be separated, the operator removes the positioning slider 30 and continues to push the driving support rod 31. At this time, the bearing shell 4 will first move downward for a short distance, and then move upward to reset. The force required for this reset process is achieved by two reset springs 7. As can be seen from the previous text, the two electrode springs 6 will also reset upward at this time. Since the two reset electrode springs 6 will be squeezed with the door frame, the electrode springs 6 will complete the overlap with the door body casting, and the power supply is automatically connected.
