Referring now to fig. 1-2, a vernier caliper 100 according to an embodiment of the present invention will be described.
As shown in fig. 1, a vernier caliper 100 according to an embodiment of the present invention includes: main scale 10, first measurement claw 20, second measurement claw 30, distance subassembly 40.
The first measuring jaw 20 and the second measuring jaw 30 are arranged on the main ruler 10 and can be close to or far away from each other; the distance assembly 40 includes two mounting portions 401, one of the two mounting portions 401 is disposed on the first measuring jaw 20 and the other is disposed on the second measuring jaw 30, and the distance between the first measuring jaw 20 and the second measuring jaw 30 on the main scale 10 is adjustable and can be locked on the main scale 10 after adjustment, so that the distance between the two mounting portions 401 is maintained, and the two mounting portions 401 are used for being mounted at both ends of a plurality of objects, so that the lengths of the plurality of objects are equal.
It can be understood that the first measuring claw 20 and the second measuring claw 30 are both arranged on the main scale 10, the first measuring claw 20 and the second measuring claw 30 can be close to or far away from each other, two installation parts 401 in the distance assembly 40 are arranged on the first measuring claw 20 and the second measuring claw 30, the first measuring claw and the second measuring claw are arranged on the main scale and have adjustable distance between each other, the target distance can be adjusted and locked on the main scale, then the distance between two ends of a target object is adjusted to enable two ends of the target object to be arranged on the two installation parts, so that the lengths of a plurality of target objects are consistent, and the multi-purpose function of one scale is realized.
Two mounting parts 401 in the distance assembly 40 are arranged on the first measuring jaw 20 and the second measuring jaw 30, when the vernier caliper 100 is used, two ends of a target object are respectively mounted on the two mounting parts 401, the two mounting parts 401 can be close to or far away from each other, and two ends of the target object can be close to or far away from each other along with the movement of the mounting parts 401, so that the purpose of adjusting the length of the target object is achieved, and the lengths of a plurality of target objects can be kept consistent.
For example, in a helicopter structure, an adjusting pull rod with a fish eye bearing is needed, and the adjusting pull rod can be adjusted and has certain adaptability. For example, three or four variable-pitch pull rods in a helicopter rotor system have high precision requirement, and when the three or four variable-pitch pull rods are measured and adjusted by a common vernier caliper, the sizes of all the pull rods are difficult to keep consistent, and the sizes of the pull rods can only be kept consistent as much as possible through continuous measurement, adjustment, re-measurement, re-adjustment and other processes. Therefore, the assembly time is wasted, and meanwhile, due to poor precision, the control precision of the controller on the rotor wing is reduced, and the hidden flight danger in the flying process of the helicopter is caused. In a usage scenario of the present invention, the target object may be the adjusting pull rod, and when a plurality of adjusting pull rods need to be adjusted to have equal length, the distance between the first measuring claw 20 and the second measuring claw 30 may be preset and fixed on the main scale 10, and then the lengths of the plurality of adjusting pull rods of the helicopter are adjusted, so that the end holes at two ends of the plurality of adjusting pull rods may be sleeved on the two mounting portions 401 of the distance assembly 40, thereby adjusting the plurality of adjusting pull rods to have equal length. Of course, the target object may also be other objects, and is not limited to the adjustment rod, and will not be described herein.
According to the vernier caliper 100 of the embodiment of the utility model, one of the two mounting parts 401 in the distance-measuring component 40 is arranged on the first measuring jaw 20, the other is arranged on the second measuring jaw 30, the first measuring jaw 20 and the second measuring jaw 30 are arranged on the main scale 10, the distance between the first measuring jaw 20 and the second measuring jaw 30 is adjustable, the target distance is adjusted and locked on the main scale, and then the distance between two ends of a target object is adjusted to enable the two ends to be mounted on the two mounting parts 401, so that the lengths of a plurality of target objects are consistent, and the function of one scale for multiple purposes is realized.
In some embodiments, as shown in fig. 2, the mounting portion 401 includes a plurality of sequentially connected divided portions 4011 having a gradually decreasing width, and a step 4011a is formed between any two adjacent divided portions 4011. That is to say, because the both ends mounted position of the target of different models is probably different in size, for example, the both ends of target are equipped with the mounting hole, and installation department 401 cover is established in the mounting hole, and the size of mounting hole is then different on the target of different models, through setting a plurality of components portion 4011 to the width and reducing gradually, is formed with step 4011a between arbitrary two adjacent components portion 4011, then can adapt to the size of different mounting holes, improves its use adaptability.
In some embodiments, as shown in fig. 2, an edge of each of the divided portions 4011 around the axis direction of the mounting portion 401 is formed with a virtual circle, and the virtual circle is matched with an end circular hole of the object. The end circular hole can be understood as the mounting hole described in the foregoing, and the split part 4011 may have different shapes, for example, the split part 4011 may be a cylinder, so that a virtual circle formed by the edge of the split part 4011 around the axis direction of the mounting part 401 is a circle formed by the cross section of the cylinder, and the split part 4011 is mounted on the target object by being sleeved on the end circular hole. For another example, the splitting part 4011 may also be a prism, the virtual circle is an external circle of the cross section of the prism, and the splitting part 4011 of the prism can also be sleeved in the end circular hole, and by adopting the method, the material can be saved, and the cost can be reduced.
In some embodiments, the first measuring jaw 20 and the second measuring jaw 30 are detachably connected to the corresponding split portion 4011. That is to say, the split part 4011 can be detached from the first measuring jaw 20 and the second measuring jaw 30, the split part 4011 is installed when the vernier caliper 100 is used, and is detached when not used, and the vernier caliper 100 can also be used as a common vernier caliper 100, so that the use is prevented from being influenced by the existence of the distance assembly 40 when the distance assembly 40 is not needed, the use convenience is improved, and the multi-purpose function of one ruler is realized.
