Description

Technical Field

[0001] The utility model belongs to the field of measuring tools, and particularly relates to a foldable caliper which is convenient for storage. Background Art

[0002] Vernier calipers are used to measure the depth of grooves or holes, etc. They have the advantages of simple structure and suitable accuracy, and are widely used in resource exploration, map making, product inspection, etc. The vernier caliper includes a longer main scale and a vernier scale that can slide on the main scale. Since the main scale is long and cannot be folded, it is troublesome to carry. In order to avoid bending due to force, the entire vernier caliper can only be stored in a longer hard box, which is inconvenient to take and put each time. In order to solve the problem of the long main scale, the prior art divides the main scale into two sections. In some schemes, the two sections of the main scale are respectively provided with screw holes and studs, and the two can be completely separated and connected or separated by rotation. In some schemes, the two sections of the main scale are connected by a rotating shaft, and the two can only be folded, but the rotating shaft has high precision requirements and high processing costs. The above two schemes have room for optimization. Utility Model Content

[0016] Reference Figure 1 and Figure 2 The utility model discloses a folding caliper that is easy to store, including a main scale and a vernier scale, both of which are provided with outer claws and inner claws, and a set screw is provided on the vernier scale. The main scale includes a head section 11 and a tail section 12, the head section 11 is provided with a boss, the tail section 12 is provided with a slot 22 that can wrap the boss, the depth of the slot 22 is greater than the height of the boss, the length and width of the slot 22 are equal to the length and width of the boss, an elastic rope 13 is connected between the upper end of the boss and the bottom of the slot 22, when the head section 11 and the tail section 12 are connected, the four sides of the head section 11 and the tail section 12 that are in contact with each other are all flush, the elastic rope 13 provides elastic force to bring the head section 11 and the tail section 12 together, and the head section 11 and the tail section 12 can be separated and folded after applying external force. An elastic cord 13 of a suitable length is selected so that when the head section 11 and the tail section 12 are folded, the elastic cord 13 still maintains a suitable elastic force.

[0017] As an improvement of the above solution, the tail section 12 is provided with a notch 23 on the front or back side of the slot 22, the size of the notch 23 is larger than the size of the elastic cord 13, and the depth of the notch 23 is smaller than the depth of the slot 22. Figure 2 As shown, the above solution is adopted to appropriately shorten the length of the elastic rope 13 when the head section 11 and the tail section 12 are bent, thereby reducing the elastic force generated by the elastic rope 13.

[0018] As an improvement of the above solution, a slope is provided inside the end surface of the slot hole 22, so that the end surface opening of the slot hole 22 is large and the inner opening is small. With the above solution, the funnel-shaped structure is conducive to the docking of the head section 11 and the tail section 12.

[0019] As an improvement of the above solution, circular holes are provided at the positions where the boss and the slot 22 are connected to the elastic rope 13, and the ends of the elastic rope 13 are embedded in the circular holes and fixed by glue.

[0020] As an improvement of the above solution, a first magnet 30 is provided on the front or back of the tail section 12, and a second magnet convenient for the adsorption of the first magnet 30 is provided on the head section 11 or the head section 11 is made of a material that can be adsorbed by the first magnet 30. With the above solution, it is convenient to properly fix the head section 11 and the tail section 12 after bending.

[0021] The solution divides the main scale into two parts, enabling the longer main scale to be folded and stored. The stored caliper can be directly held in the hand or placed in a handbag, taking up little space and not being easily bent, making it convenient to carry. After applying a pulling force between the head section 11 and the tail section 12, they can be separated or assembled, and the head section 11 and the tail section 12 are always connected by an elastic cord 13, eliminating the worry of accidental loss of either one, making it convenient to use.
