[0020] This invention provides a retractable planer blade thickness adjustment device. Compared with the prior art, it has the following advantages:
[0021] 1. This retractable planer blade thickness adjustment device, through the inclusion of a handwheel, drive shaft, first bevel gear, second bevel gear, first lead screw, adjusting block, and adjusting plate, enables adjustment of the planer blade height during use. Adjusting the blade height controls the planing thickness, enhancing the device's effectiveness. To adjust the blade height, push the push block. The push block, via a connecting rod, causes the slider to slide along the limit rod, compressing the spring. Simultaneously, the push block moves the locking gear away from the outer gear ring, allowing the handwheel to rotate. The handwheel, through the drive shaft, drives the first bevel gear to rotate. The first bevel gear drives the first lead screw to rotate via the second bevel gear. The rotation of the first lead screw causes two sets of adjusting blocks to move, which in turn causes the adjusting plate to move, thereby adjusting the height of the planer blade during use. The height of the planer blade can be observed through the scale on one side of the mounting bracket. After adjustment, the push block is released, and the spring will cause the slider to move and reset due to its elasticity. The slider, through the connecting rod and the push block, causes the locking teeth to move and reset, so that the locking teeth are tightly fitted with the outer gear ring, thereby locking the position of the handwheel and preventing accidental contact with the handwheel and causing misoperation.
[0022] 2. This retractable planer blade thickness adjustment device, through the setting of an adjustment mechanism, sliding plate, limit block, connecting frame, and locking groove, enables quick assembly and disassembly of the planer blade, facilitating maintenance and replacement. It offers higher efficiency and convenient operation. To install the planer blade, first push the connecting frame into the adjusting plate, then rotate the knob at one end of the second lead screw. This rotation causes the second lead screw to rotate, which in turn moves the sliding plate. The fixed rod limits the movement of the sliding plate to prevent deviation. The sliding plate then moves the limit block, causing it to enter the locking groove and lock the connecting frame in place, completing the planer blade installation. To disassemble the planer blade, simply rotate the knob at one end of the second lead screw in the opposite direction. The operation is convenient. Attached Figure Description

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1 to 7 This utility model provides a technical solution:
[0037] A retractable planer blade thickness adjustment device includes a mounting frame 1. Adjusting blocks 12 are equidistantly slidably connected to the inner wall of the mounting frame 1, and the adjusting blocks 12 are in contact with the inner wall of the mounting frame 1. A first lead screw 11 is equidistantly rotatably connected inside the mounting frame 1. The adjusting blocks 12 are threadedly connected to the first lead screw 11. A scale is provided on one side of the mounting frame 1. An adjusting plate 2 is fixedly connected between two adjusting blocks 12. A sliding plate 24 is slidably connected inside the adjusting plate 2. Limiting blocks 23 are fixedly connected equidistantly to one side of the sliding plate 24. The plate 2 has a connecting frame 25 slidably connected inside. The top of the connecting frame 25 is provided with locking grooves 26 that cooperate with the limiting insert 23. The bottom of the connecting frame 25 is fixedly connected with a planer 21. The adjusting plate 2 has an adjusting mechanism 4 that cooperates with the sliding plate 24. The adjusting mechanism 4 includes a second lead screw 41. The adjusting plate 2 has a second lead screw 41 rotatably connected inside. The sliding plate 24 is threadedly connected to the second lead screw 41. One end of the second lead screw 41 is fixedly connected with a knob. The outer side of the knob is provided with anti-slip texture.
[0038] In this design, the rotation of the first lead screw 11 drives the movement of two sets of adjusting blocks 12, which in turn moves the adjusting plate 2, thereby adjusting the height of the planer blade 21 during use. The height of the planer blade 21 can be observed through the scale on one side of the mounting bracket 1, and the height of the planer blade 21 can be adjusted to control the planing thickness, thus enhancing the effectiveness of the device. The rotation of the second lead screw 41 drives the movement of the sliding plate 24, which in turn moves the limiting insert 23, causing the limiting insert 23 to move into the locking groove 26, thereby locking the position of the connecting bracket 25 and completing the installation of the planer blade 21. When the planer blade 21 needs to be disassembled, simply rotate the knob at one end of the second lead screw 41 in the opposite direction, making the operation convenient.
[0039] like Figure 1 , Figure 2 and Figure 4As shown: In this scheme, a second bevel gear 15 is fixedly connected to one end of the first lead screw 11. A drive shaft 17 is rotatably connected inside the mounting bracket 1. A first bevel gear 14, which cooperates with the second bevel gear 15, is fixedly connected at equal intervals to the outside of the drive shaft 17. A handwheel 13 is fixedly connected to one end of the drive shaft 17. An external gear ring 16 is fixedly connected to the outside of the handwheel 13. A push block 34 is slidably connected to one side of the mounting bracket 1. A locking tooth 35, which cooperates with the external gear ring 16, is fixedly connected to one side of the push block 34. A fixed frame 3 is fixedly connected to the outside of the mounting bracket 1. A slider 33 is slidably connected to the inner wall of the fixed frame 3. A connecting rod 36 is fixedly connected to one side of the slider 33. The push block 34 is fixedly connected to the connecting rod 36. A limit rod 32 is fixedly connected inside the fixed frame 3. The slider 33 is slidably connected to the limit rod 32. A spring 31 is sleeved on the outside of the limit rod 32 and on one side of the slider 33.
[0040] In this design, when the height of the planer 21 needs to be adjusted, the push block 34 is pushed. The push block 34, through the connecting rod 36, causes the slider 33 to slide along the limiting rod 32, compressing the spring 31. Simultaneously, the push block 34 causes the locking gear 35 to move away from the outer gear ring 16, allowing the handwheel 13 to rotate. The handwheel 13, through the transmission shaft 17, drives the first bevel gear 14 to rotate. The first bevel gear 14, through the second bevel gear 15, drives the first lead screw 11 to rotate. The rotation of the first lead screw 11 causes the two sets of adjusting blocks 12 to move, and the adjusting blocks 12 cause the adjusting plate 2 to move. The height of the planer 21 can be adjusted by moving the spring 31. The height of the planer 21 can be observed by the scale on one side of the mounting bracket 1. The height of the planer 21 can be adjusted to control the planing thickness, thereby enhancing the effectiveness of the device. After adjustment, the push block 34 is released, and the spring 31 will drive the slider 33 to move and reset due to the elastic force. The slider 33 drives the locking tooth 35 to move and reset through the connecting rod 36 and the push block 34, so that the locking tooth 35 is tightly attached to the outer tooth ring 16, thereby locking the position of the handwheel 13 and preventing accidental contact with the handwheel 13 and causing misoperation.
[0041] like Figure 1 As shown: In this scheme, the top of the adjusting plate 2 is symmetrically and fixedly connected with a limiting slide rod 22, and the limiting slide rod 22 is slidably connected to the mounting bracket 1.
[0042] In this scheme, the movement of the adjusting plate 2 can be limited by the setting of the limiting slide bar 22 to prevent the adjusting plate 2 from deviating when moving.
[0043] like Figure 6 As shown: In this scheme, the inner wall of the adjusting plate 2 is symmetrically fixedly connected with a fixing rod 42, and the sliding plate 24 is slidably connected to the fixing rod 42.
[0044] In this design, the movement of the sliding plate 24 can be limited by the setting of the fixing rod 42 to prevent the sliding plate 24 from deviating during movement.
[0045] Working principle:
[0046] When adjusting the height of the planer blade 21, push the push block 34. The push block 34 drives the slider 33 to slide along the limit rod 32 via the connecting rod 36, compressing the spring 31. At the same time, the push block 34 drives the locking gear 35 to move away from the outer gear ring 16, allowing the handwheel 13 to rotate. The handwheel 13 drives the first bevel gear 14 to rotate via the transmission shaft 17. The first bevel gear 14 drives the first lead screw 11 to rotate via the second bevel gear 15. The rotation of the first lead screw 11 drives the two sets of adjusting blocks 12 to move. The adjusting blocks 12 drive the adjusting plate 2 to move, thereby adjusting the height of the planer blade 21 during use. The height of the planer blade 21 can be observed through the scale on one side of the mounting bracket 1. Adjusting the height of the planer blade 21 can control the planing thickness, enhancing the effectiveness of the device.
[0047] After adjustment, release the push block 34. The spring 31 will move and reset the slider 33 due to the elastic force. The slider 33 will move and reset the locking tooth 35 through the connecting rod 36 and the push block 34, so that the locking tooth 35 and the outer tooth ring 16 are tightly fitted, thereby locking the position of the handwheel 13 and preventing accidental contact with the handwheel 13 and causing misoperation.
[0048] When installing the planer blade 21, first push the connecting bracket 25 into the adjusting plate 2, and turn the knob at one end of the second lead screw 41 to drive the second lead screw 41 to rotate. The rotation of the second lead screw 41 drives the sliding plate 24 to move. The fixed rod 42 can limit the movement of the sliding plate 24 to prevent deviation. The sliding plate 24 drives the limiting block 23 to move, so that the limiting block 23 moves into the locking groove 26, thereby locking the position of the connecting bracket 25 and completing the installation of the planer blade 21. When it is necessary to disassemble the planer blade 21, simply turn the knob at one end of the second lead screw 41 in the opposite direction. The operation is convenient.
