Abstract

(57) [Summary] [Purpose] To provide a caliper that is visible even from the back side. [Structure] Visual windows 14a and 14b are formed on both sides of the vernier scale 12, so that the scale can be viewed from both sides.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a caliper for measuring the thickness of an object, the diameter of a hole, etc.

0002

[Conventional technology]

Generally, a caliper is attached to the main scale 1 and the main scale 1 in a slidable manner as shown in Figures 13 and 14. It is constructed by combining the attached vernier scale 2, and the vernier scale 2 is slid against the main scale 1. Move the inner or outer probes 6a, 6b or outer probes 7a, 7b to the object to be measured. or outside dimensions.

0003

[Problem that the idea aims to solve]

However, conventional calipers are based on the assumption that the worker is right-handed. Since the scales 3 and 5 are engraved on only one side of the scale 1 and vernier scale 2, it is difficult for left-handed workers to In some cases, it may be difficult to hold the device, and depending on the measurement location or location, the worker may be right-handed. Even if there is, it may be difficult to read scales 3 and 5 unless they are viewed from the back side.

0004 In view of the above problems, the present invention aims to provide a caliper that can be used on both sides.

[0005]

[Means to solve the problem]

The problem solving means according to the present invention is as shown in FIGS. It is combined with a vernier scale 12 that is slidably attached, and the vernier scale 12 is connected to the main scale 11. It measures the inside or outside dimension by sliding it against the main scale 1. Main scales 13a and 13b are engraved on both sides of the vernier scale 12, and main scales 13a and 13b are engraved on both sides of the vernier scale 12, respectively. Visual recognition windows 14a and 14b are formed for visual recognition, and the main scale is provided at the edges of both of the visual recognition windows 14. Subscale scales 15a and 15b are respectively engraved for comparison.

[0006]

[Effect]

In the above problem solving means, the vernier scale 12 is slid against the main scale 11 to Measure inside or outside dimensions.

[0007] At this time, if the operator is left-handed, or depending on the measurement location and location, the scale may A and 13b may be difficult to read unless viewed from the back side, but there are main marks on both sides of main scale 11. Markings 13a and 13b are carved, and visibility windows 14a and 14b and submarks are provided on both sides of the vernier scale 12. By providing the plates 15a and 15b, it is possible to use both sides.

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 shows one implementation of the present invention. A front view of the example caliper, FIG. 2 is a front perspective view, and FIG. 3 is a rear view. , FIG. 4 is a rear perspective view, FIG. 5 is a plan view, and FIG. 6 is a rear perspective view. FIG. 7 is a left side view, FIG. 8 is a right side view, and FIG. 9 is a bottom view of FIG. A-A enlarged cross-sectional view, FIG. 10 is an exploded perspective view of the fixing part, and FIG. 11 is a view of the vernier. FIG. 12 is a front view, and FIG. 12 is a right side view thereof.

[0009] As shown in the figure, the caliper of this embodiment has a main scale 11 and a main scale 11 that is slidably fitted into the main scale 11. It is made by combining the vernier 12 (vernier) that has been Measure the inner and outer dimensions in units of 1/10 mm, for example. It is something.

0010 As shown in FIGS. 1 to 6, the main scale 11 measures the inner dimensions of the object at the upper end of one end. A first inner measuring element 11a and a first outer measuring element that measures the outside of the object to be measured at the bottom of one end. 11b are fixed to form a substantially T-shape. On both sides of the main scale 11, Main scales 13a and 13b in millimeters are engraved, and as shown in FIG. A guide groove 11c is formed to slidably guide the ring 12.

[0011] The vernier 12 is a vernier formed in a square frame shape as shown in FIGS. 11 and 12. a vernier main body 12a, and a first inner measuring element 11a and a pair at the upper end of the vernier main body 12a. The second inner measuring element 12b fixed so as to face the vernier body 12a and the lower part of one end of the vernier body A second outer measuring element 12c fixed to face the first outer measuring element 11b, and a second outer measuring element 12c fixed to face the first outer measuring element 11b, It consists of a pole 12d for measuring the depth of the object to be measured.

0012 As shown in FIG. 12, the vernier main body 12a has an insertion hole for inserting the main scale 11. A mouth H is formed. 1 to 4 and 9 on both sides of the vernier main body 12a. As shown in FIG. On the lower edges of a and 14b, subscales 15a and 15b are engraved, respectively, for comparison with the main scale. ing. Further, a fixing part 16, which will be described later, is inserted into the lower end of the vernier main body 12a. An insertion port 12e is formed.

[0013] As shown in FIGS. 9 and 10, the main scale 11 and the vernier 12 are attached to each other at a fixed part 16. Fixed. The fixing part 16 moves in the longitudinal direction (X direction) within the insertion hole 12e. and a contact body 18 which can freely come into contact with the lower end of the main scale 11 and is fixed through the contact body 18. The lower end of the vernier 12 which is screwed onto both ends of the screw rod 19 is tightened. and a pair of fastening rings 20a, 20b for moving the contact body 18 in the X direction. Become. The tightening rings 20a, 20b and the wall surface 21 of the recess 18a of the contact body 18 The main scale 11 and vernier 12 are sandwiched between them and fixed to each other.

[0014] In addition, in FIGS. 7 to 9, 22 is a projection for engaging with the guide groove 11c, and 23 is a front part. This is a sliding groove on which the recording depth measurement rod 12d is slid.

[0015] In the caliper having the above configuration, the vernier scale 12 is slid against the main scale 11, and the object to be measured is Measure the inside or outside dimensions by applying the measuring probes 11a, 11b, 12b, 12c to do.

[0016] At this time, if the operator is left-handed, or depending on the measurement location and location, the scale may a, 13b, 15a, 15b may be difficult to read unless viewed from the back, but the main scale Main scales 13a and 13b are engraved on both sides of the vernier scale 11, and visual windows 14a and 14a are provided on both sides of the vernier scale 12. By providing 14b and subscales 15a and 15b, the caliper can be used on both sides. It can be used in places where it is difficult to see except from the back side, or when the worker is left-handed. Easy to measure.

[0017] It should be noted that the present invention is not limited to the above-mentioned embodiments, but may be modified within the scope of the present invention. Of course, many modifications and changes may be made to the embodiments described.

[0018] For example, in the above embodiment, both sides of the vernier 12 are square shaped in consideration of mechanical strength. Although it was formed into a frame shape, one side of the viewing windows 14a and 14b of the vernier scale 12 , as shown in FIG. 13, it may be cut out and penetrated in the sliding direction of the vernier scale 12.

[0019]

[Effect of the idea]

As is clear from the above explanation, according to the present invention, main scales are engraved on both sides of the main scale. , the vernier has visibility windows and subscales on both sides, allowing the caliper to be used on both sides. This may be difficult to see except from the back side, or if the worker is left-handed. It also has excellent effects in that it can be easily measured.
