[0050] The indicator structure for tools described in the present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an improper limitation on the technical solution of the present invention.
[0051] There are currently a variety of tools that can adjust the processing size. For example, for a planer or electric planer, it can have the function of adjusting the processing depth.
[0052] When adjusting the processing depth of a planer or electric planer, the height position of the front plate is usually adjusted by adjusting the adjustment element. Figure 1 and Figure 2 As shown, the adjusting knob 100 of the adjusting element drives the adjusted element 300, such as the front plate of a planer or electric planer, to move in the height direction through the transmission rod 200 by rotating around its own axis P, thereby adjusting the processing depth of the planer or electric planer.
[0053] Among them, Figure 2 As shown, the adjusting knob 100 is usually provided with a scale element 1, such as a scale with different processing depth sizes, and the housing of the planer or electric planer is also fixed with an indication component (not shown in the figure) used in conjunction with the scale. During the depth adjustment process, the adjusting knob 100 is rotated, and the fixed indication component will point to different depth marks on the scale, thereby realizing the processing depth indication function.
[0054] However, in reality, there is often a deviation between the scale indicated by the fixed indicator and the actual cutting depth of the planer. The reason for this deviation is that the zero position of the scale pointed by the indicator is inaccurate. Especially after the planer has been used for a period of time, due to vibration and other reasons, there is often a deviation between the zero position on the scale and the actual processing depth zero position.
[0055] In order to solve the above problem, the utility model proposes an indication structure for a tool in one embodiment, which can conveniently calibrate the indication zero position according to the actual use status of the tool.
[0056] In some embodiments, the indicator structure is used to be arranged on a tool body, the tool body includes a housing and an adjustment assembly, wherein the indicator structure includes:
[0057] a scale element, which is used to be arranged on one of the housing and the adjustment assembly;
[0058] A pointer assembly is used to be arranged on the other of the housing and the adjustment assembly; the pointer assembly includes a pointer element pointing to the scale element, and the pointer element is movably arranged relative to the other of the housing and the adjustment assembly to adjust its starting zero position relative to the scale element.
[0059] Based on this, the utility model provides a pointer element that can move relative to its setting base (such as the housing of the tool), so that the pointer element itself has a certain degree of freedom of movement. When the actual zero position does not match the indicated zero position on the scale element, the position of the pointer element can be moved so that when it points to the zero position of the scale element, it just corresponds to the zero position of the actual processing size, thereby realizing stepless adjustment and calibration of the indicated zero position.
[0060] In some more specific embodiments, the pointer assembly may be disposed on the housing, and the scale element may be correspondingly disposed on the adjustment assembly.
[0061] In some other optional implementations, the pointer assembly may also be arranged on the adjustment assembly, and the scale element may be correspondingly arranged on the housing.
[0062] The indicating structure described in the utility model has multiple setting modes:
[0063] For example, in a specific embodiment, Figure 3 As shown, the scale element 1 is arranged on the adjusting knob 100 of the adjusting assembly. The adjusting knob 100 drives the adjusted element 300, such as the front plate of the planer, to move in the height direction by rotating around its own axis, thereby adjusting the processing depth of the planer. Therefore, as the adjusting knob 100 rotates, the scale element 1 will also follow the rotation, thereby cooperating with the pointer element 400 to mark different processing depth sizes.
[0064] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, in addition to the pointer element 400, the pointer assembly also includes: a track groove 21, which is fixedly arranged on the housing of the tool (not shown in the figure); a connecting rod 22, one end of which is connected to the pointer element 400, and the other end of which passes through the track groove 21 and can slide along the track groove 21; a locking element 23, which is used to lock the position of the connecting rod 22 relative to the track groove 21 when the connecting rod 22 slides with the pointer element 400 to a desired position, such as the zero position after calibration.
[0065] In such Figure 3 , Figure 4 and Figure 5 In the illustrated embodiment, since the graduations of the scale element 1 are distributed in the circumferential direction, the track groove 21 is preferably also configured as an arc groove, and more preferably the track groove 21 is concentrically configured with the circumference of the scale distribution. This configuration can further ensure the indication accuracy of the indicating structure.
[0066] In addition, it should be noted that due to Figure 3The example indicating structure is used for a tool that uses an adjusting knob to adjust the processing size, so the track groove is set to an arc shape in conjunction with the circularly distributed scale. However, it should be noted that in other embodiments, when the scale element is distributed in a linear direction, the track groove can also be set to a linear track groove.
[0067] In some more specific embodiments, Figure 6 As shown, the connecting rod 22 can be configured as a threaded rod, and accordingly the locking element 23 can include a locking nut.
[0068] Of course, in some other more specific embodiments, the connecting rod can also be configured as a connecting pin with a pin hole, and a position adjustment hole can be provided on the wall of the track groove. Inserting the positioning pin as a locking element into the pin hole and the position adjustment hole can also lock the position of the connecting rod relative to the track groove.
[0069] In addition, in other embodiments of the present invention, Figure 7 As shown, the scale element 1 is arranged on the adjusting knob 100 of the adjusting assembly, and the adjusting knob 100 drives the adjusted element 300, such as the front plate of the planer, to move in the height direction by rotating around its own axis, thereby adjusting the processing depth of the planer. Therefore, as the adjusting knob 100 rotates, the scale element 1 will also follow the rotation, thereby cooperating with the pointer element 400 arranged on the housing 500 of the tool (only partially shown schematically), to mark different processing depth sizes.
[0070] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in this embodiment, in addition to the pointer element 400, the pointer assembly further includes: a guide rail 31, which is fixedly connected to the pointer element 400, and a guide rail groove 311 is provided on the guide rail 31; the upper end of the connecting rod 32 is connected to the housing 500, and the lower end of the connecting rod 32 is inserted into the guide rail groove 311 and can slide relative to the guide rail groove 311; Fig.11 As shown, the locking element 33 ( Figure 8 , Fig. 9 and Fig.10 4 (not shown) is connected to the connecting rod 32, which is used to lock the position of the connecting rod 32 relative to the guide groove 311 when the connecting rod 32 slides with the pointer element 400 to a required position, such as the zero position after calibration.
[0071] In some more specific embodiments, Figure 8 As shown, the guide rail 31 may be provided integrally with the pointer element 400 .
[0072] In such Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In the illustrated embodiment, since the graduations of the scale element 1 are distributed in the circumferential direction, the guide groove 311 is preferably also configured as an arc groove, and more preferably the guide groove 311 is concentrically configured with the circumference of the distribution of the graduations. This configuration can further ensure the indication accuracy of the indicating structure.
[0073] In addition, it should be noted that due to Figure 7 The example indicating structure is used for a tool that uses an adjusting knob to adjust the processing size, so the guide groove is set to an arc shape in conjunction with the circularly distributed scale. However, it should be noted that in other embodiments, when the scale element is distributed in a linear direction, the guide groove can also be set to be linear.
[0074] In some more specific embodiments, Fig.11 As shown, the connecting rod 32 can be configured as a threaded rod, and accordingly the locking element 33 can include a locking nut.
[0075] Of course, in some other more specific embodiments, the connecting rod can also be configured as a connecting pin with a pin hole, and a position adjustment hole can be set on the wall of the guide rail groove. Inserting the positioning pin as a locking element into the pin hole and the position adjustment hole can also lock the position of the connecting rod relative to the guide rail groove.
[0076] like Fig.12 As shown, in some other embodiments of the present invention, in addition to the pointer element 400, the pointer assembly may also include: a guide rail 41 fixedly connected to the pointer element 400, and a guide rail groove 411 is provided on the guide rail 41; a guide portion 44 fixedly arranged on a tool housing 500 (only partially shown schematically), the guide portion 44 is correspondingly arranged in the guide rail groove 411, and can slide relative to the guide rail groove 411; a locking assembly, which locks the position of the guide portion 44 relative to the guide rail groove 411.
[0077] In some more specific embodiments, Fig.12 As shown, the locking assembly may include a locking screw 43 and a locking nut 43 used in conjunction with each other. When the guide rail 41 moves to a position with the pointer element 400 relative to the guide portion 44, such as the zero position after calibration, the locking screw 43 and the locking nut 43 are screwed and tightened, thereby fixing the position of the guide rail 41 relative to the guide portion 44. It can be seen that, unlike the embodiment described above in which the screw is used as a guide element sliding along the guide rail groove or track groove, in this embodiment, the screw is provided as a locking element.
[0078] In some more specific embodiments, Fig.12As shown, the guide rail 41 may be provided integrally with the pointer element 400 .
[0079] In addition, when the scale element 1 is distributed in the circumferential direction, the guide groove 411 is preferably also set as an arc groove, and more preferably the guide groove 411 is set concentrically with the circumference of the scale distribution. This setting method can further ensure the indication accuracy of the indicating structure.
[0080] In addition, it should be noted that due to Fig.12 The example indicating structure is more suitable for tools that use adjusting knobs to adjust the processing size, so the guide groove is set to an arc shape with the circularly distributed scale. However, it should be known that in other embodiments, when the scale element is distributed in a linear direction, the guide groove can also be set to be linear.
[0081] In addition, in some further embodiments of the present invention, Fig.13 As shown, the scale element 1 is arranged on the adjusting knob 100 of the adjusting assembly, and the adjusting knob 100 drives the adjusted element 300, such as the front plate of the planer, to move in the height direction by rotating around its own axis, thereby adjusting the processing depth of the planer. Therefore, as the adjusting knob 100 rotates, the scale element 1 will also follow the rotation, thereby cooperating with the pointer element 400 arranged on the housing 500 of the tool (only partially shown schematically), to mark different processing depth sizes.
[0082] like Fig.13 and Fig.14 As shown, in this embodiment, in addition to the pointer element 400, the pointer assembly also includes a rotating shaft 26, and the pointer element 400 is connected to the rotating shaft 26 and can rotate around the axis of the rotating shaft. When the pointer element 400 rotates around the rotating shaft 26 to a required position, such as the zero position after calibration, it stops rotating, and the locking element locks the angle of rotation of the pointer element around the axis of the rotating shaft.
[0083] Furthermore, in some more specific embodiments, such as Fig.15 and Fig.16 As shown, the rotating shaft 26 can be set as a screw, and the locking element is constructed as a threaded hole 27 opened on the housing 500; the tail end of the screw passes through the hole on the pointer element 400 and is threadedly connected with the threaded hole 27 opened on the housing 500.
[0084] Of course, in other embodiments, a separate locking nut may be used as a locking element. When the pointer element 400 rotates around the rotating shaft 26 to a desired position, the locking nut is connected to the screw to lock its rotational position.
[0085] like Fig.15 and Fig.16As shown, in some more specific embodiments, an elastic element 28 having elastic force in the axial direction may be further provided between the pointer element 400 and the housing 500. The provision of the elastic element may provide a certain redundancy in the axial direction. In some more specific examples, the elastic element may be a spring, and in some other more specific examples, the elastic element may be a rubber ring.
[0086] In another embodiment, the utility model further provides a tool, which includes a tool body, and the tool body includes a shell and an adjustment component; in addition, the tool also includes the indication structure as described above.
[0087] In some more specific embodiments, the tool may be a power tool, and in some other more specific embodiments, the tool may also be a hand tool.
[0088] In some more specific embodiments, the adjustment assembly of the tool may include an adjusting knob and an adjusted element (such as the front plate of a planer or electric planer), the adjusting knob rotates around its own axis to adjust the position of the adjusted element, the scale element is arranged in the circumferential direction of the adjusting knob, and the pointer assembly is arranged on the housing.
[0089] In a specific example, the tool can be a planer or electric planer that can adjust the processing depth. In another specific example, the tool can be a circular saw that adjusts the cutting depth.
[0090] In addition, the utility model can also be used for other tools with processing size adjustment and measurement functions.
[0091] Through the above arrangement, the utility model can conveniently and quickly realize the zero position calibration of the tool adjustment element, thereby ensuring the accuracy of tool processing, avoiding the wear tolerance of the processing blade or other elements of the tool, and improving the convenience of using the tool.
