Wherein the adjusting assembly 316, the first sleeve 312 and the second sleeve 320 are combined into an adjusting unit.
The set screw 310 includes a top portion 3102, a body 3104 and a bottom portion 3106, wherein the top portion 3102 has a diameter greater than the diameter of the body 3104 and the body 3104 has a diameter greater than the diameter of the bottom portion 3106. The bottom portion 3106 is threaded for threading the blind hole 3162 in the top of the adjustment assembly 316.
The adjustment cap 302 has a scale on an outer peripheral surface thereof, and a first engagement portion (a first tooth portion 3026 in the present embodiment) on an inner peripheral surface thereof. In addition, the adjusting cap 302 extends from the top center to the cylinder 3021, and a positioning structure (including a first groove 3027 and a second groove 3028) is disposed on the outer circumferential surface of the cylinder 3021 for cooperating with the positioning pin 348, so that the adjusting cap 302 can be positioned at the first position or the second position when performing the zeroing setting. A screw through hole 3022 is also provided in the cylinder 3021, and an inner flange 3024 is provided in the screw through hole 3022. The body 3104 and bottom 3106 of the set screw 310 may extend through the screw through hole 3022, but the top 3102 of the set screw 310 is restrained within the screw through hole 3022 by the inner flange 3024.
The first sleeve 312 has a sleeve body 3121, at least one (two in this embodiment) tubular portion 3122 extends from the top of the sleeve body 3121, and a second engaging portion (a second tooth portion 3124 in this embodiment) is disposed at the end of the tubular portion 3122 for engaging with the first tooth portion 3026 on the inner peripheral surface of the adjustment cover 302, so that when the adjustment cover 302 rotates, the first sleeve 312 is driven to rotate around the axis L1. The first press ring 314 is disposed around the top of the first sleeve 312 and at one end of the tubular portion 3122. The elastic member 349 is disposed in the tubular portion 3122, one end of the elastic member 349 abuts against the first pressing ring 314, and the other end of the elastic member 349 abuts against the positioning pin 348, so that the positioning pin 348 protrudes out of the other end of the tubular portion 3122, and the protruding positioning pin 348 extends into the first groove 3027 or the second groove 3028 of the adjusting cover 302 to generate a positioning effect on the adjusting cover 302.
The bottom of the sleeve body 3121 of the first sleeve 312 is inserted into the top of the second sleeve 320 until contacting the protruding wall 3204 within the second sleeve 320.
The height setting ring 335 is screwed to the external thread of the second sleeve 320 by the internal thread, so that when the user detaches the adjusting cap 302, the height setting ring 335 can be rotated (rotated relative to the second sleeve 320) to move the height setting ring 335 up and down, and when the ZERO point position of the compensating mechanism 30 is determined, the user can rotate the height setting ring 335 to move down until contacting the base cap 318, and then the fixing screw 334 abuts against the second sleeve 320, the height setting ring 335 cannot be rotated relative to the second sleeve 320 to be positioned at a height position, so as to provide a ZERO point STOP (ZERO p) effect when the compensating operation is performed.
The second sleeve 320 includes at least one (two in this embodiment) laterally extending tubular portion 3202 for receiving the spring 329 and the ball 328. The base cover 318 and the base 336 combine to form a receiving space for receiving the segmented Ring (Click Ring)324 and the tubular portion 3202 of the second sleeve 320. A plurality of parallel grooves 3242 are provided on the inner surface of segmented ring 324. The second press ring 306 is used to press and fix the base cover 318.
The alignment ring 330 is fixed outside the base cover 318, the adjustment cover 302 partially covers the alignment ring 330, the outer peripheral surface of the adjustment cover 302 is provided with scales, and the outer peripheral surface of the alignment ring 330 is provided with a mark line which can provide alignment function when the adjustment cover 302 rotates.
In this embodiment, the adjusting element 316 is an adjusting screw, the top of the adjusting element 316 penetrates into the first sleeve 312 and is screwed into the first sleeve, the top of the adjusting element 316 is provided with a blind hole 3162, and the bottom 3106 of the limiting screw 310 is screwed into the blind hole 3162. The adjusting member 316 has a protruding stop wall 3164 formed on the outer surface thereof, and the protruding wall 3204 of the second sleeve 320 is clamped between the bottom of the sleeve body 3121 of the first sleeve 312 and the stop wall 3164 of the adjusting member 316, so that when the first sleeve 312 rotates, the first sleeve 312 can rotate the second sleeve 320 by using the friction between the bottom of the sleeve body 3121 and the protruding wall 3204 of the second sleeve 320, and when the second sleeve 320 rotates, the second sleeve 320 can rotate the adjusting member 316 by using the friction between the protruding wall 3204 and the stop wall 3164.
When the user wants to perform the springing compensation, the user rotates the adjustment cover 302, and the adjustment cover 302 sequentially drives the first sleeve 312, the second sleeve 320, and the adjustment assembly 316 to rotate, as can be seen from the foregoing, the adjustment cover 302 and the adjustment assembly 316 in this embodiment are indirectly linked. Since the adjustment assembly 316 is threaded into the base 336 while the base 336 is stationary, the rotating adjustment assembly 316 is simultaneously moved up or down along the axis L1 to correct the impact point.
As previously discussed, when the adjustment cap 302 rotates the first sleeve 312, the first sleeve 312 will also rotate the second sleeve 320, such that the ball 328 rolls between the grooves 3242 on the inner surface of the segmented ring 324, thereby generating a Click sensation and sound.
If the user wants to return to the zero position, the user can continuously rotate the adjustment cover 302 downward, and the height setting ring 335 (screwed on the second sleeve 320) will descend along with the second sleeve 320 and the adjustment assembly 316 until it abuts against the base cover 318, which means returning to the zero position.
To perform the zeroing setting, the user lifts the adjustment cap 302 up to separate the first tooth portion 3026 of the adjustment cap 302 from the second tooth portion 3124 of the first sleeve 312, as shown in fig. 4, so that the adjustment cap 302 does not rotate the first sleeve 312 when the user rotates the adjustment cap 302 to perform the zeroing setting. After the zeroing setting operation is completed, the user can press back the adjustment cap 302 to re-engage the first tooth portion 3026 of the adjustment cap 302 with the second tooth portion 3124 of the first sleeve 312 for subsequent impact correction operations. It should be noted that when the user lifts the adjusting cap 302 up, the positioning pin 348 is forced to exit the first recess 3027 under the guidance of the slope of the first recess 3027, the elastic member 349 is compressed at the same time, until the second recess 3028 rises to the position of the positioning pin 348, and the restoring force of the elastic member 349 causes the positioning pin 348 to enter the second recess 3028 to generate a new positioning, as shown in fig. 4, so that the adjusting cap 302 will not fall down. When the zeroing setting is completed, the user can press back the adjusting cover 302 to force the positioning pin 348 to exit the second recess 3028 guided by the slope of the second recess 3028 while compressing the elastic member 349, and then the first recess 3027 descends to the side of the positioning pin 348, and the positioning pin 348 is positioned again in the first recess 3027 by the restoring force of the elastic member 349, and returns to the state shown in fig. 3.
It should be noted that the bottom 3106 of the limit screw 310 is screwed into the blind hole 3162 on the top of the adjusting assembly 316, so that when the adjusting cover 302 is lifted, the limit screw 310 is not lifted along with the adjusting cover 302, and the top 3102 of the limit screw 310 has a larger diameter than the body 3104 and is limited by the inner flange 3024 of the screw through hole 3022, so that the top 3102 of the limit screw 310 cannot leave the screw through hole 3022, thereby ensuring that the adjusting cover 302 cannot be separated from the limit screw 310.
Referring to fig. 5 and 6, another embodiment of the compensation mechanism 50 of the distance measuring compensation device of the present invention includes a set screw 510, an adjusting cover 502, a positioning ring 548, an adjusting unit (including an adjusting element 516), a ball (e.g., a steel ball) 528, a spring 529, a positioning ring 530, an O-ring 540, an E-ring 550 and a base 536.

The body 5104 and bottom 5106 of the setscrew 510 can pass through the screw through hole 5022, but the top 5102 of the setscrew 510 is restrained by the inner flange 5024 within the screw through hole 5022. The adjusting cap 302 further extends downward from the top to form an annular wall 5020, the annular wall 5020 surrounds the cylinder 5021, and a first engaging portion (in this embodiment, a first tooth portion 5026) is disposed on the inner circumferential surface of the annular wall 5020 for engaging with a second engaging portion (in this embodiment, a second tooth portion 5164) of the adjusting assembly 516, so that the adjusting cap 502 rotates to drive the adjusting assembly 516 to rotate around the axis L2. Further, the outer peripheral surface of the adjustment cap 502 is provided with a scale.
The adjusting element 516 is sequentially provided with a second groove 5167, a first groove 5168 and a blind hole 5162 from top to bottom, wherein the second groove 5167 or the first groove 5168 cooperates with the receiving groove 5025 to receive the positioning ring 548, and the positioning ring 548 is clamped therein to generate interference deformation and position the adjusting cover 302 at different positions.
In addition, a second tooth portion 5164, a tubular portion 5169, an annular groove 5165 and an external thread 5166 are sequentially disposed from top to bottom outside the adjusting component 516, wherein the tubular portion 5169 extends laterally to accommodate the spring 529 and the ball 528, the annular groove 5165 accommodates an O-ring 540, the O-ring 540 is clamped between the adjusting component 516 and the base 536 to generate a waterproof and airtight effect, and the external thread 5166 of the adjusting component 516 is mutually screwed with the internal thread 5364 of the base 536.
The base 536 is hollow, and the base 536 has an accommodating space 5361 and a through hole 5363 therein, wherein the accommodating space 5361 is used for accommodating the tubular portion 5169 of the adjusting assembly 516, and a plurality of parallel grooves 5362 are disposed on an inner surface of the accommodating space 5361. The through hole 5363 is connected to the receiving space 5361, and an inner thread 5364 is formed on an inner surface of the through hole 5363 for being screwed with the outer thread 5166 of the adjusting assembly 516.

To perform impact correction, the user rotates the adjustment cap 502, the adjustment cap 502 rotates the adjustment element 516 via the first tooth 5026 and the second tooth 5164, and the adjustment element 516 is screwed to the base 536 while the base 536 is fixed, so that the rotating adjustment element 516 moves upward or downward along the axis L2 to correct the impact point. An E-clip 550 is provided at the bottom of the adjustment member 516 to prevent the adjustment member 516 from moving upward and away from the base 536.
When the adjustment cap 502 rotates the adjustment assembly 516, the ball 528 disposed at one end of the tubular portion 5169 will roll between the groove 5362 of the seat 536, which can generate a click feeling and sound.
To perform the zeroing setting, the user lifts the adjustment cap 502 to separate the first tooth 5026 of the adjustment cap 502 from the second tooth 5164 of the adjustment assembly 516, as shown in fig. 7, so that the adjustment cap 502 does not rotate the adjustment assembly 516 when the user rotates the adjustment cap 502 to perform the zeroing setting. After the zeroing setting operation is completed, the user can press back the adjustment cap 502 to re-engage the first teeth 5026 of the adjustment cap 502 with the second teeth 5164 of the adjustment assembly 516 for subsequent impact correction operations. It is noted that, when the positioning ring 548 is sandwiched between the first groove 5168 and the receiving groove 5025, the user can lift the adjusting cover 502 to force the positioning ring 548 to leave the first groove 5168 and enter the second groove 5167 to generate a new positioning, so that the adjusting cover 502 will not fall down. When the zeroing setting is completed, the user can press back on the adjustment cap 502, forcing the retaining ring 548 back into the first groove 5168 to be retained, i.e., to the position shown in FIG. 6.
As mentioned above, the retaining ring 548 is sandwiched between the second groove 5167 and the receiving groove 5025 (or between the first groove 5168 and the receiving groove 5025) to generate interference deformation, wherein one of the factors influencing the interference deformation is that the retaining ring 548 has hardness difference in the selected material, the deformation degree of the retaining ring 548 with higher hardness is smaller than that of the retaining ring 548 with lower hardness, and the other factor influencing the interference deformation is that the depths of the first groove 5168 and the second groove 5167 of the adjusting assembly 516 can determine the interference with the retaining ring 548, and the combination of the two factors further influences the tightness feeling of the upward and downward pressing actions of the adjusting cover 502. Referring to fig. 8 and 9, wherein fig. 8 is a partially enlarged view of VIII of fig. 7, fig. 9 is a schematic view of fig. 8 with the positioning ring 548 removed, assuming that the cross-sectional area of the receiving groove 5025 is a, the cross-sectional area of the second groove 5167 is B, the cross-sectional area of the first groove 5168 is B', and the cross-sectional area of the positioning ring 548 before the deformation due to interference is C, in order to provide a proper operation feeling, the present invention at least satisfies the following condition, and in the preferred embodiment, the present invention satisfies the following two conditions:
0.7C≦(A+B)≦C；
0.7C≦(A+B’)≦C。
it should be noted that the bottom 5106 of the limiting screw 510 is screwed into the blind hole 5162 of the adjusting element 516, so that when the adjusting cap 502 is lifted up, the limiting screw 510 is not lifted up along with the adjusting cap 502, and the top 5102 of the limiting screw 510 has a larger diameter than the body 5104 and is limited by the inner flange 5024 of the screw through hole 5022, so that the top 5102 of the limiting screw 510 cannot leave the screw through hole 5022, thereby ensuring that the adjusting cap 502 cannot be separated from the limiting screw 510.
As can be seen from the above description, the correction mechanism of the present invention can perform the zeroing setting without using a hand tool.
