Description

Technical Field

[0001] The utility model relates to a measuring tool, in particular to a multifunctional measuring ruler. Background Art

[0002] A vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth. The vernier caliper consists of a main scale and a sliding vernier scale attached to the main scale. When 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 the groove and the barrel. Figure 1 As shown, for a workpiece 100 having an inner hook groove 101 , a conventional vernier ruler cannot measure the inner hook groove 101 of the workpiece 100 . Utility Model Content

[0003] The utility model aims to provide a multifunctional ruler which can measure the hook groove in the workpiece.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] The utility model is a multifunctional ruler, comprising a main ruler, a vernier ruler, inner measuring claws and outer measuring claws; the vernier ruler is slidably connected to the main ruler, the inner claws of the main ruler and the inner claws of the vernier ruler constitute the inner measuring claws, and the outer claws of the main ruler and the outer claws of the vernier ruler constitute the outer measuring claws; the utility model also comprises two movable inner hooks; the outer claws of the main ruler and the outer claws of the vernier ruler are respectively provided with movable inner hooks, and the two movable inner hooks are arranged opposite to each other.

[0006] The lower end of the movable inner hook card is fixed on the outer claw of the main ruler or the outer claw of the vernier ruler, and the upper end of the movable inner hook card is provided with a barb and the barb faces outwards.

[0007] The utility model also comprises a locking screw; the movable inner hook is fixed on the outer claw of the main ruler or the outer claw of the vernier ruler through the locking screw.

[0008] The end of the inverted hook on the movable inner hook card is rectangular or triangular. After adopting the above scheme, since the utility model includes a main scale, a vernier scale, an inner measuring claw, an outer measuring claw, and a movable inner hook card, the outer claws of the main scale and the outer claws of the vernier scale are respectively installed with movable inner hook cards, and the two movable inner hook cards are arranged opposite to each other, and the movable inner hook cards can be extended into the inner hook groove of the workpiece for measurement.

[0009] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 is a schematic diagram of the second type of artifact;

[0012] Figure 3 It is a schematic diagram of the first embodiment of the utility model;

[0013] Figure 4 It is an exploded view of the first embodiment of the utility model;

[0014] Figure 5 It is an exploded view of the second embodiment of the utility model. DETAILED DESCRIPTION

[0015] like Figure 3 , Figure 4 As shown, the first embodiment of the multifunctional ruler of the utility model comprises a main ruler 1, a vernier ruler 2, an inner measuring jaw 3, an outer measuring jaw 4, two movable inner hooks 5, and a locking screw 6.

[0016] The vernier scale 2 is slidably connected to the main scale 1, the inner jaw 11 of the main scale 1 and the inner jaw 21 of the vernier scale 2 constitute an inner measuring jaw 3, and the outer jaw 12 of the main scale 1 and the outer jaw 22 of the vernier scale 2 constitute an outer measuring jaw 4; the outer jaw 12 of the main scale 1 and the outer jaw 22 of the vernier scale 2 are respectively equipped with movable inner hooks 5, and the two movable inner hooks 5 are arranged opposite to each other.

[0017] Furthermore, the lower end of the movable inner hook 5 is fixed to the outer claw 12 of the main scale 1 or the outer claw 22 of the vernier scale 2 by a locking screw 6, and the upper end of the movable inner hook 5 has a barb 51 and the barb 51 faces outward, and the end of the barb 51 is rectangular.

[0018] The working principle of this utility model:

[0019] Since the outer claws 12 of the main scale 1 and the outer claws 22 of the vernier scale 2 are respectively provided with movable inner hook cards 5, the two movable inner hook cards 5 are arranged opposite to each other, and when measuring, the barbs 51 on the movable inner hook cards 5 extend into the inner hook groove 101 (such as Figure 1 Measured as shown).

[0020] like Figure 5 The second embodiment of the multifunctional ruler of the utility model is shown in the figure. Its structure is basically the same as the first embodiment, except that the end of the movable inner hook 5' and the inverted hook 51' is triangular, which is used for measuring Figure 2 The inner hook groove 101 ′ of the workpiece 100 ′ is shown.

[0021] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the specification should still fall within the scope covered by the patent of the present invention.
