Description
Technical Field
[0001] This utility model relates to the field of vernier calipers, and in particular to a double-sided vernier caliper with rapid reading. Background Technology
[0002] A vernier caliper is a measuring instrument used to measure length, inner and outer diameters, and depth. A vernier caliper consists of a main scale and a sliding vernier scale attached to the main scale. Both the main scale and vernier scale have two sets of movable jaws: an inner jaw and an outer jaw. The inner jaw is typically used to measure the inner diameter, while the outer jaw is typically used to measure the length and outer diameter.
[0003] Existing vernier calipers have limitations in use. Some vernier calipers have relatively small engravings, and different users have different visual abilities. When users with poor eyesight look at vernier calipers with small values, they may misread the values because they cannot see the accurate values clearly. Therefore, we propose a double-sided vernier caliper with fast reading to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a double-sided scale vernier caliper with rapid reading, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A double-sided vernier caliper with rapid reading includes: a main scale; a first vernier scale and a second vernier scale slidably connected to the outer side of the main scale; two connecting blocks fixedly connected between the first and second vernier scales; a groove on the inner side of the second vernier scale; a first block slidably connected to the inner side of the groove; a rotating roller rotatably connected to the inner side of the first block; a magnifying glass and a first plate fixedly connected to the outer side of the rotating roller; multiple first slots on the outer side of the first plate; a bracket fixedly connected to the top of the second vernier scale; a third plate rotatably connected to the front side of the bracket; two first posts fixedly connected to the front side of the third plate; connecting rods rotatably connected to the outer sides of the two first posts; second posts rotatably connected to the other ends of the two connecting rods; second blocks fixedly connected to the rear sides of the two second posts; and first inserts fixedly connected to the sides of the two second blocks that are close to each other, with the outer sides of the two first inserts movably inserted into the corresponding first slots.
[0007] Preferably, a circular plate is fixedly connected to the outer side of each of the two No. 1 columns, and a rotating shaft is fixedly connected to the front side of each circular plate. A long block is fixedly connected to the top of the No. 2 auxiliary ruler, and the outer side of the rotating shaft is rotatably connected to the inner side of the long block.
[0008] Preferably, a handwheel is fixedly connected to the outer side of the rotating shaft, a spring is fixedly connected to the front side of the long block, a lever is fixedly connected to the other end of the spring, a second insert block is fixedly connected to the left side of the lever block, and multiple second slots adapted to the second insert block are opened on the outer side of the handwheel, and the outer side of the second insert block is movably inserted into the inner side of the corresponding second slot.
[0009] Preferably, a fixing rod is fixedly connected to the front side of the long block, a fixing cylinder is slidably connected to the outside of the fixing rod, and the left side of the fixing cylinder is fixedly connected to the right side of the lever block.
[0010] Preferably, a second plate is fixedly connected to the rear side of the first block, the outer side of the second plate is slidably connected to the inner side of the second auxiliary ruler, and two connecting blocks are fixedly connected to the rear side of the second plate. A third block is slidably connected to the inner side of each of the two connecting blocks, and the other side of each of the two third blocks is fixedly connected to one side of the corresponding second block.
[0011] Preferably, the main scale and the first auxiliary scale are provided with scale lines on both the front and rear sides.
[0012] In this utility model, a double-sided scale rapid reading vernier caliper can magnify the scale lines on the main scale and the first vernier scale by using a magnifying glass, thereby making it easier for users to quickly observe the numerical values. The scale lines at different positions can be magnified by sliding the first block and rotating the angle of the magnifying glass. When the user adjusts the angle of the magnifying glass, he first turns the handwheel, which causes the rotating shaft to start rotating. Due to the rotation of the rotating shaft, the circular plate starts to drive the third plate to rotate.
[0013] In this invention, a double-sided scale rapid reading vernier caliper is initiated by two connecting rods. This causes the second block to drive the first insertion block to move horizontally, thus causing the first insertion block to leave the first slot. At this point, the user can adjust the magnifying glass to a specified angle. Furthermore, by rotating the handwheel in the opposite direction, the first insertion block enters the corresponding first slot, and the user stops moving the lever, causing the second insertion block to enter the corresponding second slot. At this moment, the position of the magnifying glass is fixed, and the user can magnify the corresponding value, making it easier for the user to observe the vernier caliper.
[0014] This utility model has a reasonable structural design. Through the cooperation between the handwheel, connecting rod, block number one, circular plate, bracket, plate number one, plate number two, and block number three, the magnifying glass can be moved or its angle adjusted, making it easier for users to clearly observe the magnitude of the values and quickly read them out.

[0022] In this embodiment, circular plates 15 are fixedly connected to the outer sides of both No. 1 columns, and rotating shafts 20 are fixedly connected to the front sides of both circular plates 15. A long block 17 is fixedly connected to the top of the No. 2 auxiliary ruler 3, and the outer side of the rotating shaft 20 is rotatably connected to the inner side of the long block 17. A handwheel 21 is fixedly connected to the outer side of the rotating shaft 20. A spring 24 is fixedly connected to the front side of the long block 17. A lever 23 is fixedly connected to the other end of the spring 24. A No. 2 insertion block 22 is fixedly connected to the left side of the lever 23.

The outer side of the No. 2 insertion block 22 is movably inserted into the inner side of the corresponding No. 2 slot, which makes the position of the handwheel 21 fixed at this time.
[0023] In this embodiment, a fixed rod is fixedly connected to the front side of the long block 17, and a fixed cylinder is slidably connected to the outside of the fixed rod. The left side of the fixed cylinder is fixedly connected to the right side of the lever block 23. A second plate 8 is fixedly connected to the rear side of the first block 5.

The user can then adjust the magnifying glass 19 to the desired angle. Further, rotating the handwheel 21 in the opposite direction causes the first insertion block 11 to enter the corresponding first slot, and stopping the toggle block 23. This allows the second insertion block 22 to enter the corresponding second slot. At this point, the position of the magnifying glass 19 is fixed, allowing the user to magnify the corresponding values, thus facilitating observation of the vernier caliper.
