As shown in fig. 1, an embodiment of the present utility model provides a caliper 100 including two measuring jaws 110 and a blade 120, wherein the blade 120 includes a body portion 121, one of the measuring jaws 110 is fixedly connected to the body portion 121, and the other measuring jaw 110 is movably connected to the body portion 121. When the measurement is performed, the measuring jaw 110 fixed to the body portion 121 serves as a start point measuring jaw 110, and the other movable measuring jaw 110 serves as an end point measuring jaw 110, thereby measuring the distance between the two points.

The inventor finds that in the existing callipers, the shape of the tail end of the measuring claw is fixed and cannot be changed, for example, the measuring claw of the traditional vernier callipers is approximately in a right trapezoid shape, and the shape is beneficial to rapidly measuring the distance between two sides of an object, but if the center distance between two holes needs to be measured, the measuring process becomes complicated, and the measuring efficiency is reduced.

In view of the above, the measuring jaw 110 of the caliper 100 is modified in the present utility model. Specifically, the measuring jaw 110 includes a main body 111 and at least one measuring head 112, each measuring head 112 is detachably connected to the main body 111, and the measuring head 112 has any one of a conical shape, a tetrahedron shape, a cylindrical shape, and a hexahedral shape. Thus, as shown in fig. 5 and 6, when the center distance between two holes or the distance between the center and the edge of the hole needs to be measured, the measurement can be easily performed by only replacing the measuring head 112.

As shown in fig. 2, the measuring head 112 includes a connecting portion 1121 and a measuring portion 1122, the connecting portion 1121 and the main body portion 111 are detachably connected, and the measuring portion 1122 and the connecting portion 1121 are connected. The measuring part 1122 is in threaded connection or clamping connection with the first sleeve 1111 to realize detachable connection, so that the connecting structure is simple, and the dismounting efficiency is high.

When the conical measuring head 112 is used, the measuring portion 1122 is conical, and the measuring claw 110 is required to be placed on the circular hole, and the measuring portion 1122 of the measuring head 112 is located exactly at the center point of the circular hole, so that the center distance between two holes or the distance between the sides of the center distance between two holes can be accurately measured.

When the cylindrical measuring head 112 is used, the measuring part 1122 is cylindrical, and the measuring part 1122 is provided with scales, so that the depth of the blind hole can be measured.

In the related art, an auxiliary ruler is added on the measuring jaw, the auxiliary ruler is perpendicular to the ruler body, and the auxiliary ruler can be used for setting the measuring jaw to move, so that the depth of the blind hole is measured. With such a structure, the volume of the caliper is increased.

In the present embodiment, the measuring unit 1122 is formed in a cylindrical shape, and the measuring head 112 and the main body 111 are detachably connected, so that the caliper 100 can be reduced in size and can be stored conveniently.

When the hexahedral or tetrahedral measuring head 112 is used, the measuring portion 1122 is hexahedral or tetrahedral, and the surface of the two measuring heads 112 that are close to or far from each other is a plane perpendicular to the blade 120, so that the measuring head 112 is in contact with the surface of the object, and the measuring result is more accurate.

The measuring section 1122 and the connecting section 1121 are provided so as to be insulated from each other, and the measuring head 112 and the main body 111 are provided so as to be insulated from each other. Since the blade 120 is mostly made of a metal material, a short circuit is easily caused when it is required to measure an electrified object. Therefore, the measurement unit 1122 is made of an insulating material such as plastic or silica gel, and thus, the battery is not short-circuited or damaged when the positioning hole of the battery module or the battery pack is measured.

As shown in fig. 4, the main body 111 includes a first sleeve 1111 and a second sleeve 1112, one end of the first sleeve 1111 is detachably connected to the measuring head 112, and the other end of the first sleeve 1111 is movably connected to the second sleeve 1112 and sleeved in the second sleeve 1112. In this way, the body 111 of the present utility model is made to have a telescopic structure.

When the caliper 100 is used to measure the interior of a device or machine, the measuring area is not accessible due to the limited length of the measuring jaw 110 of the caliper 100, resulting in no measurement. By setting the body 121 to be of a telescopic structure, the length of the measuring jaw 110 can be changed according to actual measurement requirements, so that the caliper 100 is suitable for measuring objects to be measured in various scenes. In addition, when the caliper 100 is not required to be used, the size of the main body 111 can be reduced, and the storage is facilitated.

Further, the second sleeve rod 1112 is provided with a plurality of clamping holes 11121, the plurality of clamping holes 11121 are arranged at intervals along the length direction of the second sleeve rod 1112, one end of the first sleeve rod 1111, which is far away from the measuring head 112, is provided with a clamping joint 11111, and the clamping joint 11111 is movably connected with the clamping hole 11121. In this way, the lengths of the two measuring jaws 110 on the caliper 100 can be simultaneously kept consistent, so that the measurement result is more accurate.

It will be appreciated that in other embodiments, a third loop bar, a fourth loop bar, etc. may be provided in addition to the first and second loop bars 1111, 1112, each loop bar being nested in sequence, so that the body portion 111 forms a telescopic structure.

Of course, a splicing method may be adopted, that is, the main body 111 is divided into at least two sections, and each section of main body may be spliced to achieve the purpose of changing the length of the main body 111.

In this embodiment, one of the two measuring jaws 110 is fixedly connected to the body 121, and the other measuring jaw 110 is movably connected to the body 121. Specifically, one of the measuring jaws 110 is fixed to the end of the body portion 121 at zero scale, and the measuring jaw 110 is disposed perpendicular to the body portion 121.

As shown in fig. 1 and 3, a slide rail 123 is provided on the back surface of the body 121, and the slide rail 123 is provided along the length direction of the body 121; the caliper 100 further includes a slider 124, where the slider 124 is slidably connected to the slide rail 123, and the other measuring jaw 110 is connected to the slider 124, so that the measuring jaw 110 moves in an opening and closing manner relative to the fixed measuring jaw 110, and the two measuring jaws 110 are disposed in parallel and spaced apart relation.

The body 121 of the ruler 120 is provided with a scale on the front, the ruler 120 is also provided with a digital display device 122, and the digital display device 122 is used for displaying the reading of the ruler 120, so that the measuring efficiency is improved.

Specifically, the body 121 is internally provided with a high-precision rack, the sliding block 124 drives the rack to rotate, and then drives the circular grid sheet to rotate, the displacement of the measuring jaw 110 is converted into a pulse signal by using the photoelectric pulse counting principle, and the measured size is digitally displayed on a screen through a counter and a display.

The body portion 121 further has a fixing screw 1241, where the fixing screw 1241 is used to fix the slider 124, so as to fix the measuring jaw 110 connected with the slider 124, thereby facilitating quality inspection operation on the product.

In this embodiment, the slide block 124 and the fixing screw 1241 are made of plastic materials, so that the weight of the caliper 100 can be reduced, and on the other hand, when the user performs the measurement of the positioning holes of the battery module and the battery pack, the ruler body is prevented from contacting the charged object to cause the user to get an electric shock.

The ruler body 120 is also provided with a handle 125, and the handle 125 and the digital display device 122 are both arranged on the surface of one side of the body part 121 far away from the measuring jaw 110, so that the operation of a user is convenient.
