[0002] The door and window handle knob base is the core structural connector of the door and window handle system. As the assembly basis for the knob and handle transmission mechanism, it directly bears the rotational force of the knob and realizes the effective transmission of force. Its surface needs to be machined with precise countersunk screw holes and positioning holes. This base is mostly made of non-ferrous metal materials such as zinc alloy and aluminum alloy by die casting.

A universal joint is connected to the output rod, and a drill rod is connected to the universal joint. A sliding frame is mounted on the movable seat, and the drill rod is slidably connected to the sliding frame.

[0006] As a further optimization of the present invention, a driven gear is fixedly provided on the connecting rod, and a threaded sleeve is fixedly provided on the column, the threaded sleeve being threaded onto the lead screw.

[0007] As a further optimization of the present invention, the driving mechanism includes a servo motor mounted on a gearbox, the output end of the servo motor passing through the gearbox and connected to a driving rod, the driving gear being fixedly mounted on the driving rod, and a reduction gear set being provided between the driving gear and the driven gear.

[0008] As a further optimization of the present invention, the sleeve rod is rotatably mounted on the gearbox and the movable seat respectively. A bevel gear one is fixedly mounted on the sleeve rod. A groove is opened on the bevel gear one. A pawl is rotatably arranged in the groove. An elastic element is provided between the pawl and the bevel gear one. Ratchets are provided at both ends of the output rod. The ratchet wheels abut against the pawls in the bevel gear one respectively. A bevel gear two is rotatably mounted on the movable seat and meshed between the bevel gears one.

[0009] As a further optimization of the present invention, the universal connection mechanism includes a spline shaft and a spline sleeve slidably sleeved on the spline shaft, and universal joints are connected between the spline shaft and the output rod and between the spline sleeve and the drill rod.

[0010] As a further optimization of the present invention, the sliding frame is provided with a sliding groove, and a bolt is connected in the sliding groove. Multiple mounting brackets are connected to the sliding frame by bolts. The mounting bracket is provided with a horizontal groove, and the bolt is slidably disposed in the horizontal groove. The drill rod is rotatably disposed on the mounting bracket.

[0011] As a further optimization of the present invention, the rotating table includes a mounting base, which is fixedly mounted on a base frame. A second servo motor is fixedly mounted on the mounting base. A connecting shaft is rotatably mounted on the mounting base. A rotating disk is fixedly mounted on the upper end of the connecting shaft. The output end of the second servo motor is fixed to the connecting shaft. A mounting plate is fixedly mounted on the rotating disk. A positioning seat is fixedly mounted on the mounting plate. A plurality of positioning columns are provided on the positioning seat.

[0012] A door and window handle knob base includes a decorative cover, a fixed seat is provided inside the decorative cover, the fixed seat includes a base body, a positioning strip is provided on the base body, a sleeve is provided on the positioning strip, and a locking transmission assembly connected to the sleeve is provided on the base body.

[0015] The beneficial effects of this invention are as follows: Unlike existing technologies, in actual use, the drive mechanism can simultaneously achieve two power outputs. The drive gear, in conjunction with the reduction gear set, drives the lead screw to rotate, driving the moving seat to rise and fall smoothly. At the same time, the linkage with the one-way output mechanism enables the drill rod to rotate continuously, simplifying the overall structure and reducing energy consumption. The one-way output mechanism, through the cooperation of bevel gear, pawl, elastic element and ratchet, ensures that the output rod always rotates in the forward direction during the raising and lowering of the moving seat, avoiding the cutting edge from scraping the hole wall at an angle other than the design angle when the drill rod rotates in the reverse direction, resulting in a large number of burrs, scratches or even chipping on the hole wall. The spline shaft, spline sleeve and universal joint of the universal connection mechanism can be used to adapt to the fine adjustment of the drill rod position, thus making it suitable for drilling processes of different types of workpieces.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1, such as Figure 11 - Figure 13As shown, a door and window handle knob base includes a decorative cover 9, a fixing seat 11 inside the decorative cover 9, a base 11 including a seat body 111, a positioning strip 101 on the base body 111, a sleeve 10 on the positioning strip 101, a through hole 112 on the base body 111, countersunk screw holes 113 on the base body 111 on both sides of the through hole 112 and at one diagonal, positioning holes 114 on both sides of the through hole 112, a protruding rod on the positioning strip 101 that is embedded in the positioning hole 114, a receiving groove 115 at another diagonal of the base body 111, and a locking transmission assembly 1 connected to the sleeve 10 on the base body 111. 2. The decorative cover 9 provides external protection against dust and water for the internal components, preventing impurities from entering and affecting the operation of the internal structure. The fixing seat 11 provides a stable mounting carrier for each component through the seat body 111. The design of the protruding rod of the positioning strip 101 embedded in the positioning hole 114 can realize the positioning of the positioning strip 101 and the seat body 111, ensuring the coaxiality of the subsequent installation of the sleeve 10. The countersunk screw holes 113 are distributed on both sides and one diagonally opposite side, which can realize the rigid fixation of the seat body 111 and the door and window sash through the countersunk screws, improving the fixation stability and avoiding the screws being exposed and affecting the aesthetics. The through hole 112 provides a through channel for the locking transmission component 12, ensuring the installation space of the transmission structure.

[0020] like Figure 12 As shown, the locking transmission assembly 12 includes a fixed head 124, a sleeve 10 fixedly sleeved on the fixed head 124, the fixed head 124 penetrating the seat body 111 through a through hole 112, a limiting wheel 121 fixedly disposed at the lower end of the fixed head 124, the limiting wheel 121 having an array of limiting grooves, a steel ball 122 slidably disposed in a receiving groove 115, and a spring 123 disposed between the steel ball 122 and the seat body 111. The fixed head 124 can provide fixed support for the sleeve 10, and can also transmit rotational torque through the through hole 112 through the seat body 111, while being fixedly connected to the lower limiting wheel 121 to ensure the synchronicity of the rotational movement. The sleeve 10 is fixedly fitted onto the fixed head 124 and cooperates with the positioning strip 101 to further enhance coaxiality and prevent offset or jamming during rotation. The array of limiting grooves on the limiting wheel 121 can engage with the steel ball 122, providing a basis for gear positioning. The steel ball 122 slides in the receiving groove 115, and with the elastic preload of the spring 123, it can achieve a cycle of engagement and disengagement with the limiting groove, forming a clear gear feedback feel. At the same time, after the handle is released, it can be pushed into the limiting groove by the spring 123 to fix the handle position. The spring 123 continuously provides a stable preload to the steel ball 122, ensuring the reliability of gear positioning.

[0021] The working process of the door and window handle knob base is as follows: The decorative cover 9 acts as an external protective structure to cover the internal components. The fixing seat 11 installed inside it is rigidly fixed to the door and window sash through the countersunk screw holes 113 on the seat body 111. The positioning strip 101 is positioned by inserting the protruding rod into the positioning hole 114 of the seat body 111. The sleeve 10 is fitted onto the fixing head 124 of the locking transmission component 12 and cooperates with the positioning strip 101 to ensure coaxiality. When the handle is rotated, the handle square shaft drives the sleeve 10 to rotate, which in turn drives the fixing head 124 to rotate synchronously. 4. The lower limiting wheel 121 rotates accordingly. At this time, the steel ball 122 in the receiving groove 115, under the elastic preload of the spring 123, engages and disengages with the limiting groove on the limiting wheel 121 in a cyclic action, forming a clear gear positioning and operation feedback feel. At the same time, the fixing head 124 transmits the rotational torque to the door and window lock box to realize locking or unlocking. When the handle is released, the spring 123 pushes the steel ball 122 into the limiting groove of the limiting wheel 121 to fix the handle position. Throughout the process, the decorative cover 9 continuously protects the internal structure from dust and water.

[0022] like Figure 1 - Figure 3 As shown, a drilling device for a door and window handle knob base includes a base frame 1 and a column 2 mounted on the base frame 1. A guide rail is mounted on the column 2, and a movable seat 3 is slidably mounted on the column 2 via the guide rail. A lead screw 32 is rotatably mounted on the movable seat 3. A bellows cover is fitted onto the lead screw 32 between the column 2 and the movable seat 3. A connecting rod 321 is fixedly connected to the lead screw 32. A gearbox 31 is mounted on the movable seat 3, and a driven gear 322 is fixedly mounted on the connecting rod 321. A threaded sleeve 33 is fixedly mounted on the column 2, and the threaded sleeve 33 is threaded onto the lead screw 32. The base frame 1 provides a stable load-bearing foundation for the entire device. The design effectively avoids vibrations during drilling operations that could affect machining accuracy and collects debris; the sliding fit between the column 2 and the moving seat 3 strictly limits the lifting trajectory of the moving seat 3, preventing deviation; the fixed connection between the lead screw 32 and the connecting rod 321 ensures lossless power transmission, and the driven gear 322 enables power connection; the gearbox 31 provides enclosed protection for the internal transmission components, isolating machining debris and dust, and improving the stability and service life of the components; the precision thread fit between the threaded sleeve 33 and the lead screw 32 enables smooth, controllable, and precise positioning of the lifting action of the moving seat 3, meeting the feed accuracy requirements of drilling operations.

[0023] like Figure 4 - Figure 5As shown, a drive mechanism 4 is installed inside the gearbox 31. The drive mechanism 4 includes a drive gear 412 and a servo motor 41 mounted on the gearbox 31. The output end of the servo motor 41 passes through the gearbox 31 and is connected to a drive rod 411. The drive gear 412 is fixedly mounted on the drive rod 411. A reduction gear set 42 (the reduction gear set 42 is existing technology and will not be described in detail) is provided between the drive gear 412 and the driven gear 322. The servo motor 41 can realize the control of speed and direction, providing a stable and controllable power source for the device and adapting to different drilling conditions. The fixed connection between the drive rod 411 and the drive gear 412 can ensure efficient power transmission and reduce energy loss. The reduction gear set 42 can not only effectively increase the output torque to meet the power requirements of the lead screw 32 driving the moving seat 3 to lift and lower, but also reduce the transmission speed to avoid power impact on the lead screw 32, driven gear 322 and other components. At the same time, in conjunction with the enclosed environment of the gearbox 31, it further improves the stability and reliability of the transmission.

[0024] like Figure 6 - Figure 8 As shown, the movable base 3 is equipped with multiple one-way output mechanisms 7 connected to the drive gear 412. Each one-way output mechanism 7 includes an output rod 72, with sleeve rods 71 ​​rotatably mounted at both ends of the output rod 72. One sleeve rod 71 is fixedly mounted with a driven gear 711 that meshes with the drive gear 412. The sleeve rods 71 ​​are rotatably mounted on the gearbox 31 and the movable base 3, respectively. A bevel gear 73 is fixedly mounted on the sleeve rod 71. A groove is formed on the bevel gear 73, within which a pawl 731 is rotatably arranged. An elastic element 732 is provided between the pawl 731 and the bevel gear 73. Ratchets 74 are provided at both ends of the output rod 72, and the ratchet 74 respectively mesh with… The pawl 731 inside the bevel gear 73 engages with the bevel gear 73, and the bevel gear 75 rotatably mounted on the movable seat 3 is connected between the bevel gears 73. The sleeve 71 provides a stable mounting base for the output rod 72, ensuring coaxiality during rotation. The driven gear 711 enables the power connection between the drive gear 412 and the one-way output mechanism 7, ensuring transmission. The cooperation between the pawl 731 and the elastic element 732 enables the bevel gear 73 to drive the output rod 72 to rotate synchronously when rotating in the forward direction, and to achieve a one-way transmission effect of free rotation when rotating in the reverse direction. The bevel gear 75 enables the reverse linkage of the two sets of bevel gears 73, ultimately ensuring that the output rod 72 always outputs power in the forward direction during the lifting and lowering process of the movable seat 3.

[0025] like Figure 6As shown, a universal joint mechanism 6 is connected to the output rod 72, and a drill rod 5 is connected to the universal joint mechanism 6. The universal joint mechanism 6 includes a spline shaft 61 and a spline sleeve 62 that is slidably sleeved on the spline shaft 61. Universal joints 63 are connected between the spline shaft 61 and the output rod 72, and between the spline sleeve 62 and the drill rod 5. The sliding fit design of the spline shaft 61 and the spline sleeve 62 can flexibly adapt to the position fine adjustment requirements of the drill rod 5, ensuring that the drill rod 5 can still stably receive the power of the output rod 72 after the position is adjusted. The universal joint 63 can effectively compensate for the installation deviation and angle change between the output rod 72 and the drill rod 5, avoid power loss, component wear or vibration caused by position offset, ensure the continuity and stability of power transmission, and provide good adaptability for multi-position and multi-angle drilling operations.

[0026] like Figure 6 and Figure 9 As shown, a sliding frame 52 is provided on the movable base 3. The sliding frame 52 has a sliding groove, in which bolts are connected. Multiple mounting brackets 51 are connected to the sliding frame 52 by bolts. The mounting brackets 51 have horizontal grooves, in which bolts are slidably disposed. The drill rod 5 is rotatably mounted on the mounting bracket 51. The mounting brackets 51 provide stable rotational support for the drill rod 5, preventing the drill rod 5 from shaking during drilling and ensuring drilling accuracy. The sliding groove of the sliding frame 52, in conjunction with the bolts, allows for overall position adjustment of the mounting bracket 51. The horizontal groove on the mounting bracket 51 allows for fine-tuning of the horizontal position of the drill rod 5. This dual adjustment structure can adapt to the processing requirements of different hole positions and base specifications, improving the versatility of the device. The bolt connection method facilitates the fixing and disassembly of the mounting brackets 51, balancing adjustment flexibility and structural stability.

[0027] like Figure 1 and Figure 10As shown, a rotating platform 8 is mounted on the base frame 1. The rotating platform 8 includes a mounting base 81, which is fixedly mounted on the base frame 1. A servo motor 82 is fixedly mounted on the mounting base 81. A connecting shaft 831 is rotatably mounted on the mounting base 81. A rotating disk 83 is fixedly mounted on the upper end of the connecting shaft 831. The output end of the servo motor 82 is fixedly connected to the connecting shaft 831. A mounting plate 84 is fixedly mounted on the rotating disk 83. A positioning seat 85 is fixedly mounted on the mounting plate 84. A positioning block is provided on the positioning seat 85. The mounting base 81 provides a stable mounting foundation for all components of the rotating platform 8, ensuring a tight connection with the base frame 1 and preventing damage during rotation. Displacement is generated; servo motor 82 can control the speed and angle of the connecting shaft 831, ensuring the positioning accuracy of the rotating disk 83 rotating 90 degrees; the fixed connection between the connecting shaft 831 and the rotating disk 83 ensures efficient power transmission, and the mounting plate 84 provides a flat mounting surface for the positioning seat 85; the positioning seat 85 is provided with multiple positioning posts, and the receiving groove 115 and the through hole 112 are respectively fitted into each positioning post, so that the positioning seat 85 can position the base to be processed. With the automatic rotation of the rotating table 8, continuous processing of the holes on both sides of the base can be realized without the need for manual secondary disassembly and positioning, which greatly reduces positioning errors and improves batch processing efficiency.

[0028] It should be noted that when the door and window handle knob base drilling device is working, the base body 111 to be processed is first fixed by the positioning seat 85 of the rotating table 8 to prevent displacement during the drilling process. Then, the servo motor 41 is started, and its output end passes through the gearbox 31 and is firmly connected to the drive rod 411. The power is transmitted to the drive rod 411, which drives the drive gear 412 fixed on the rod to rotate at a constant speed. The drive gear 412 simultaneously achieves two power outputs: on the one hand, it adjusts the speed and increases the torque through the reduction gear set 42, driving the driven gear 322 on the connecting rod 321 to rotate smoothly, causing the lead screw 32, which is fixed to the connecting rod 321, to rotate synchronously. Since the lead screw 32 and the threaded sleeve 33 on the column 2 form a precision thread engagement, it drives the movable seat 3, which is slidably mounted on the column 2, to achieve smooth lifting and lowering, providing axial feed power for the drilling operation; when the drive mechanism 4 drives the lead screw 32 to rotate forward and drive the movable seat 3 to descend, the drive gear 412 drives the driven gear 711 meshing with it in the one-way output mechanism 7 to rotate. The driven gear 711 drives the corresponding sleeve rod 71 to rotate synchronously, and the bevel gear 73 on the sleeve rod 71 rotates accordingly. The pawl 731 in its groove is engaged in the tooth groove of the ratchet 74 at the end of the output rod 72 under the elastic force of the elastic element 732, thereby driving the output rod 72 to rotate synchronously forward. At this time, the first bevel gear 73 on the other rod 71 rotates in the opposite direction through the second bevel gear 75 in the intermediate transmission. Its pawl 731 is squeezed by the ratchet 74 to overcome the elastic force of the elastic element 732 and contract, disengaging from the tooth groove, allowing the first bevel gear 73 to idle on the output rod 72 without affecting the direction of the output rod 72. When the drive mechanism 4 drives the lead screw 32 to reverse and drive the moving seat 3 to rise, the rod 71 connected to the driven gear 711 rotates in the opposite direction. The pawl 731 on its first bevel gear 73 disengages from the ratchet 74 and idles, while the other bevel gear 73 rotates in the forward direction through the transmission of the second bevel gear 75. Through the cooperation of the pawl 731 and the ratchet 74, the output rod 72 is driven to maintain forward rotation again, ultimately realizing that the output rod 72 always outputs power in the forward direction during the lifting and lowering process of the moving seat 3. The output rod 72 drives the drill rod 5 to rotate continuously via the universal joint mechanism 6. The universal joint mechanism 6 consists of a spline shaft 61, a spline sleeve 62, and a universal joint 63. The sliding fit between the spline shaft 61 and the spline sleeve 62 allows for fine-tuning of the drill rod 5's position, while the universal joint ensures stable power transmission between the spline shaft 61 and the spline sleeve 62 at various angles. Simultaneously, the position of each drill rod 5 can be adjusted via the sliding frame 52 and the mounting frame 51: the sliding groove on the sliding frame 52 engages with the bolts to move the mounting frame 51 as a whole; the transverse groove on the mounting frame 51 allows the bolts to slide, enabling fine-tuning of the drill rod 5's horizontal position, and the bolts provide a locking mechanism, aligning the drill rod 5 with the target holes such as the countersunk screw holes 113 and the positioning holes 114 on the base to be machined.After drilling is completed on one side of the through hole 112, the servo motor 82 of the rotating table 8 starts, driving the connecting shaft 831 to rotate the rotating disk 83, the mounting disk 84 and the positioning seat 85 by 90 degrees, so that the target hole on the other side of the base is aligned with the drill rod 5, and then continuous drilling operation is carried out.

[0029] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
