Description

Technical Field

[0001] The utility model relates to the field of vernier calipers, in particular to a vernier caliper with a marking function. Background Art

[0002] A vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth. It consists of a main scale and a slidable vernier attached to the main scale. Viewed from the back, the vernier is a whole, and the depth gauge is connected to the vernier scale, which can measure the depth of grooves and barrels.

[0003] Certain items need to be measured to determine whether they need to be cut or not. When measuring them, the measurement personnel need to hold a vernier caliper in one hand and use a marker to mark the measured area with the other hand. However, this method is cumbersome and inconvenient for the measurement personnel to operate. Therefore, a vernier caliper with a marking function is proposed to solve the above problem.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4 A vernier caliper with a marking function is provided. The utility model comprises a vernier caliper body 1, an outer measuring jaw of the vernier caliper body 1 is provided with a give way groove, the outer side of the give way groove is fixedly connected with a fixing sleeve 2, the outer side of the fixing sleeve 2 is fixedly connected with an L-shaped supporting plate 3, the front side of the fixing sleeve 2 is slidably connected with a connecting plate 4, the outer side of the L-shaped supporting plate 3 is provided with a pulling device 5 fixedly connected with the connecting plate 4, a threaded hole is provided inside the connecting plate 4, a first threaded rod 6 is threadedly connected inside the threaded hole, a protective frame 7 is rotatably connected to the bottom of the first threaded rod 6, a fixing device 8 is provided inside the protective frame 7, and a marking pen 9 is provided inside the protective frame 7.

[0028] Among them, the pulling device 5 includes a tension spring 51 fixedly connected to the left side of the L-shaped support plate 3, a pulling plate 52 is fixedly connected to the left side of the tension spring 51, and a connecting rod 53 is fixedly connected to the right side of the pulling plate 52, which penetrates and extends to the outside of the L-shaped support plate 3 and is fixedly connected to the connecting plate 4.

[0029] In this embodiment, during actual use, the pull plate 52 is pulled, the tension spring 51 is stretched, and the connecting plate 4 is moved under the drive of the connecting rod 53, thereby driving the marking pen 9 to move, and the pull plate 52 is released, and the marking pen 9 returns to its original position under the action of the tension spring 51.

[0030] A sliding groove is provided inside the fixing sleeve 2, and a sliding plate 10 is fixedly connected to the outer side of the connecting plate 4 and is slidably connected to the sliding groove.

[0031] In this embodiment, during actual use, the movement of the connecting plate 4 causes the slide plate 10 to move, and the slide groove provides a sliding space for the slide plate 10 and limits the moving direction of the slide plate 10 , thereby stabilizing the movement of the connecting plate 4 .

[0032] The fixing device 8 includes a second threaded rod 81 connected to the internal thread of the protection frame 7 , a second knob 82 is arranged on the outer side of the second threaded rod 81 , and a pressure plate 83 located inside the protection frame 7 is rotatably connected to the outer side of the second threaded rod 81 .
