DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a planetary gearbox that is easy to fix includes a planetary gearbox body 1; a base 11 is connected to the bottom of the planetary gearbox body 1; first slide grooves 12 are provided on both sides of the base 11; multiple groups of first clamping grooves 13 are provided on both sides of the first slide grooves 12; a slide plate 14 is slidably connected to the middle of the first slide grooves 12; a positioning column 15 is fixedly connected to the ends of the slide grooves 14; a slide rod 16 is slidably connected to the middle of the slide plate 14; a rectangular plate 17 is fixedly connected to the ends of the slide rod 16; a threaded sleeve 18 is fixedly connected to the middle of the rectangular plate 17; a bolt 19 is rotatably connected to the middle of the threaded sleeve 18; during operation, when the planetary gearbox body 1 needs to be fixed, the slide plate 14 can be first slid in the first slide groove 12 until the surface of the slide plate 14 contacts the fixing part, the positioning column 15 can be clamped in the first clamping groove 13, and the slide plate 14 will slide synchronously in the middle of the slide rod 16 when sliding, and then The bolt 19 is rotated to rotate in the middle of the threaded sleeve 18, so that the bottom of the bolt 19 moves toward the top of the fixing part until the bottom of the bolt 19 is against the top of the fixing part, so that the planetary gear box body 1 can be fixed. In this step, the planetary gear box body 1 and the fixing part can be fixed left and right and up and down by moving the slide plate 14 and rotating the bolt 19, so as to prevent the planetary gear box body 1 from being easily caused by the force generated by the transmission during the operation of the planetary gear box body 1. Unnecessary movement or vibration of the planetary gear box body 1, thereby affecting the transmission efficiency of the planetary gear box body 1, and easily causing damage to its internal gears and bearings and other components, thereby reducing the service life of the planetary gear box body 1. The mutual cooperation between the positioning column 15 and the first slot 13 can limit the slide plate 14, thereby improving the stability of the slide plate 14 and reducing the slide plate 14 from sliding due to external interference after being fixed.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the middle part of the slide bar 16 is provided with a plurality of second slots 2; the middle part of the slide plate 14 is fixedly connected with a plurality of support plates 21; the middle part of the support plates 21 is slidably connected with a slide column 22; the end of the slide column 22 is fixedly connected with a triangular clamping plate 23; the middle part of the slide column 22 is connected with a first tension spring 24; when working, when the slide plate 14 slides, it will drive the support plate 21 to move synchronously, and the movement of the support plate 21 will drive the slide column 22 and the triangular clamping plate 23 to move, and the end of the triangular clamping plate 23 will generate friction with the slide bar 16 during the movement, and under the influence of the friction force, the triangular clamping plate 23 will drive the slide column 22 to slide toward the two sides of the slide plate 14 at the middle part of the support plate 21, and the triangular clamping plate 23 will slide when it slides. The first tension spring 24 is squeezed to compress the first tension spring 24. When the slide plate 14 slides to the specified position, the first tension spring 24 will rebound, thereby driving the slide column 22 and the triangular clamping plate 23 to slide toward the slide rod 16 until the bottom of the triangular clamping plate 23 is stuck in the middle of the second clamping groove 2. This step can limit the slide rod 16 by clamping the triangular clamping plate 23 in the middle of the second clamping groove 2, thereby preventing the slide rod 16 from being easily affected by the outside world and sliding at the slide plate 14 after the planetary gear box body 1 is fixed, so that the bolt 19 is moved, thereby reducing the fixing effect of the bolt 19 and affecting the connection tightness between the planetary gear box body 1 and the fixing part.

[0025] like Figure 1 , Figure 2 As shown, the middle of the slide plate 14 is fixed with multiple groups of pillars 3; the ends of the pillars 3 are fixed with arc plates 31; the middle of the arc plate 31 is connected with multiple groups of second tension springs 32; the ends of the second tension springs 32 are connected with elastic plates 33; when working, when the sliding slide plate 14 is fixedly clamped, the elastic plate 33 will contact the fixed part before the slide plate 14, and the slide plate 14 continues to slide at this time. The elastic plate 33 will be affected by the extrusion force and deformed, and at the same time, it will press the second tension spring 32 to compress the second tension spring 32, so that the elastic plate 33 is close to the arc plate 31. This step is to be affected by the first Due to the limitation of the length of the slide groove 12, when the diameter of the fixing part is small, the slide plate 14 is not easy to contact the fixing part well, which leads to a reduction in the fixing effect of the slide plate 14. At this time, the fixing range of the slide plate 14 can be increased through the action of the arc plate 31, thereby reducing the occurrence of such situations. Through the mutual cooperation of the elastic plate 33 and the second tension spring 32, it can adapt to a variety of fixing parts of different shapes, thereby preventing the arc plate 31 from being easily restricted by the shape of the arc plate 31 when the fixed object is irregular in shape, thereby reducing the fixing effect of the arc plate 31.

[0026] like Figure 2 , Figure 3As shown, second slide grooves 41 are fixedly connected to both sides of the slide plate 14; a plurality of inclined rods 4 are provided at the bottom of the base 11; during operation, when the slide plate 14 is slid, the second slide grooves 41 will move with the movement of the slide plate 14, and the end of the second slide grooves 41 will slide along the inclined rods 4 when moving. This step can limit the sliding trajectory of the slide plate 14 through the cooperation between the second slide grooves 41 and the inclined rods 4, thereby preventing the slide plate 14 from being easily displaced due to uneven force when sliding, thereby causing the two sides of the slide plate 14 to tilt, affecting the fixation of the planetary gearbox body 1.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, the bottom of the bolt 19 is fixedly connected to an extrusion plate 5; the bottom of the extrusion plate 5 is connected to a sponge pad 51; during operation, when the bolt 19 is rotated, the extrusion plate 5 will contact the fixing part before the bolt 19, and the sponge pad 51 can relieve the pressure of the bolt 19 on the fixing part. In this step, the opening of the extrusion plate 5 can increase the fixing area of ​​the bolt 19, thereby strengthening the fixing effect of the bolt 19. Through the action of the sponge pad 51, the situation in which the surface of the fixing part is easily damaged due to the pressure brought by the bolt 19 can be reduced.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the ends of the sliding column 22 and the sliding rod 16 are fixedly connected to the limit pad 6; when working, the limit pad 6 can limit the sliding trajectory of the sliding column 22 and the sliding rod 16. This step is that the sliding column 22 and the sliding rod 16 are prone to slide out of their carriers when sliding, thereby reducing the fixing effect of the planetary gearbox body 1. At this time, the opening of the limit pad 6 can effectively reduce the occurrence of such situations.

[0029] like Figure 1 , Figure 2 As shown, the middle part of the elastic plate 33 is connected with an arc-shaped friction plate 7; during operation, when the elastic plate 33 squeezes and clamps the fixing part, the arc-shaped friction plate 7 can increase the friction force between the elastic plate 33 and the fixing part. This step can further increase the fixing effect of the planetary gearbox body 1 through the action of the arc-shaped friction plate 7, thereby making the planetary gearbox body 1 more stably fixed.

[0030] Working principle: during operation, when the planetary gearbox body 1 needs to be fixed, the slide plate 14 can be slid in the first slide groove 12 first, until the surface of the slide plate 14 contacts the fixing part, the positioning column 15 can be clamped in the first slot 13, and the slide plate 14 will slide synchronously in the middle of the slide rod 16 when sliding, and then the bolt 19 is rotated to make the bolt 19 rotate in the middle of the threaded sleeve 18, so that the bottom of the bolt 19 moves toward the top of the fixing part until the bottom of the bolt 19 is against the top of the fixing part, so that the planetary gearbox body 1 can be fixed. In this step, the planetary gearbox body 1 and the fixing part can be fixed left and right and up and down by moving the slide plate 14 and rotating the bolt 19, thereby preventing the planetary gearbox body 1 from being moved during operation. The force generated by its transmission can easily cause unnecessary movement or vibration of the planetary gearbox body 1, thereby affecting the transmission efficiency of the planetary gearbox body 1, and can also easily cause damage to its internal gears, bearings and other components, thereby reducing the service life of the planetary gearbox body 1. The mutual cooperation between the positioning column 15 and the first slot 13 can limit the slide plate 14, thereby improving the stability of the slide plate 14 and reducing the slide plate 14 from sliding due to external interference after being fixed. During operation, when the slide plate 14 slides, it will drive the support plate 21 to move synchronously, and the movement of the support plate 21 will drive the slide column 22 and the triangular clamping plate 23 to move, and the end of the triangular clamping plate 23 will generate friction with the slide rod 16 during the movement. , under the influence of friction, the triangular clamping plate 23 will drive the sliding column 22 to slide toward the two sides of the slide plate 14 at the middle of the support plate 21. When the triangular clamping plate 23 slides, it will squeeze the first tension spring 24 to compress the first tension spring 24. When the slide plate 14 slides to the specified position, the first tension spring 24 will rebound, thereby driving the sliding column 22 and the triangular clamping plate 23 to slide toward the slide rod 16 until the bottom of the triangular clamping plate 23 is stuck in the middle of the second slot 2. This step can limit the slide rod 16 by clamping the triangular clamping plate 23 in the middle of the second slot 2, thereby preventing the slide rod 16 from being easily affected by the outside world and sliding at the slide plate 14 after the planetary gear box body 1 is fixed, so that the bolt 19 is moved, thereby reducing the fixing of the bolt 19. The second extension spring 32 is compressed, so that the elastic plate 33 is brought closer to the arc plate 31. This step is limited by the length of the first slide groove 12. When the diameter of the fixing piece is small, the slide plate 14 is not easy to contact the fixing piece well, which leads to the situation that the fixing effect of the slide plate 14 is reduced. At this time, the fixing range of the slide plate 14 can be increased through the action of the arc plate 31, thereby reducing the occurrence of such situations.The elastic plate 33 and the second tension spring 32 cooperate with each other to adapt to a variety of different shapes of fixing parts, so as to prevent the situation that when the fixed object is an irregular shape, the arc plate 31 is restricted by the shape of the arc plate 31, which makes it difficult for the arc plate 31 to fit well with the fixed object, thereby reducing the fixing effect of the arc plate 31. During operation, when the slide plate 14 is slid, the second slide groove 41 moves with the movement of the slide plate 14, and the end of the second slide groove 41 slides along the inclined rod 4 when moving. This step can limit the sliding trajectory of the slide plate 14 through the cooperation of the second slide groove 41 and the inclined rod 4, thereby preventing the slide plate 14 from being easily offset due to uneven force when sliding, thereby causing the two sides of the slide plate 14 to tilt, affecting the fixation of the planetary gear box body 1. During operation, when the bolt 19 is rotated, the extrusion plate 5 will contact the fixing part before the bolt 19, and the sponge pad 51 can alleviate the problem. The bolt 19 exerts pressure on the fixing part. In this step, the fixing area of ​​the bolt 19 can be increased by opening the extrusion plate 5, thereby strengthening the fixing effect of the bolt 19. Through the action of the sponge pad 51, the situation that the pressure brought by the bolt 19 can easily cause damage to the surface of the fixing part can be reduced. During operation, the limit pad 6 can limit the sliding trajectory of the sliding column 22 and the sliding rod 16. This step is that the sliding column 22 and the sliding rod 16 are prone to slide out of their carriers when sliding, thereby reducing the fixing effect of the planetary gearbox body 1. At this time, the opening of the limit pad 6 can effectively reduce the occurrence of such a situation. During operation, when the elastic plate 33 squeezes and clamps the fixing part, the arc-shaped friction plate 7 can increase the friction between the elastic plate 33 and the fixing part. In this step, through the action of the arc-shaped friction plate 7, the fixing effect of the planetary gearbox body 1 can be further increased, thereby making the planetary gearbox body 1 more stably fixed. ,
