Description

Vernier caliper convenient for drawing midpoint
Technical Field
The utility model relates to a slide caliper, concretely relates to conveniently draw slide caliper at mid point.
Background
When a vernier caliper is used for measuring the length of an object, for example, when a bench worker conducts scribing in operation, a central line of a certain regular surface or a middle point of a certain line segment needs to be drawn, most of the measurement adopted by people is conducted by using a measuring ruler, the obtained result is divided by two, and a straight line or a point which is needed by people is drawn on the object by using the measuring ruler, so that the use is inconvenient.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a conveniently draw vernier caliper of mid point solves current vernier caliper and can not directly draw the mid point, awkward problem.
The technical scheme is as follows: convenient slide caliper who draws mid point, including cradling piece, stock and frame pole, the cradling piece is fixed on slide caliper, frame pole one end and cradling piece sliding connection, the other end and slide caliper blade sliding connection, be provided with marking off head and rolling element on the frame pole, stock one end is rotated with the slide caliper front end and is connected, the other end and slide caliper rear end sliding connection, be provided with the spout on the stock, the rolling element card on the frame pole slides along the spout in the spout.
The frame rod is provided with a first clamping groove matched with the support rod, and one end of the frame rod is clamped on the support rod through the clamping groove.
A second clamping groove matched with the frame rod is formed in the vernier caliper body, and one end of the frame rod is clamped in the second clamping groove and slides along the second clamping groove.
The vernier caliper front end is provided with the pivot, and the vernier caliper rear end is provided with the boss, stock one end is passed through the through-hole and is installed in the pivot, and the other end passes through logical groove card on the boss.
And a fastening nut for fixing the moving position of the frame rod is arranged at the rear end of the vernier caliper.
The marking head is detachably connected with the frame rod.
Has the advantages that: the utility model discloses can be accurate find corresponding position and carve required mid point or central line, simple structure, convenient operation solves work piece central point or central line measurement and sign problem.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-6, a vernier caliper convenient for marking a midpoint comprises a main caliper 11, an auxiliary caliper 10, a dial 12, an outer measuring claw 8, an inner measuring claw 13, a support rod 3, a long rod 2 and a frame rod 7, wherein the support rod 3 is fixed on the vernier caliper, one end of the frame rod 7 is provided with a first clamping groove matched with the support rod 3, the support rod 3 is inserted into the first clamping groove, the other end of the support rod is inserted into a second clamping groove matched with the frame rod 7 and arranged on a vernier caliper body and slides along the second clamping groove, the frame rod 7 is provided with a marking head 6 and a rolling body 5, the vernier caliper body below the vernier caliper is provided with a rotating shaft 14, the right-side auxiliary caliper 10 body is provided with a boss 1, the distance between the rotating shaft 14 and the boss 1 satisfies a stock theorem, the long rod 2 is provided with a through groove and a non-penetrating sliding groove, the rolling body 5 is arranged in the non-penetrating sliding groove, the rolling body 5 is connected with a marking head 6, and the marking head 6 moves along with the movement of the rolling body 5 in the non-penetrating chute 4, and the central point is determined along with the movement. Stock 2 is connected through logical groove and slide caliper's boss sliding connection, and stock one end is connected with the last pivot 14 of slide caliper through the through-hole that sets up, forms the revolute pair. And a fastening nut 9 for fixing the moving position of the frame rod is arranged at the rear end of the vernier caliper. The marking head can be changed, can also be for the metal object of being convenient for marks such as pencil lead, and the frame pole cooperates with the second draw-in groove for can make a round trip to slide in the second draw-in groove, in order to reach flexible effect, when the frame pole moved suitable position and need fix a position, the fastening nut 9 of screwing made it fixed.
Use the utility model discloses the time, the auxiliary ruler 10 in right side stimulates right, and stock 2 also begins to change thereupon, and its one end is fixed rotary motion by pivot 14, and the another side contains the position that leads to the groove then makes reciprocating sliding on by fixed boss 1 to the realization is under the tensile shrink's of slide caliper condition, stock 2 moves thereupon together. After the outer measuring grab 8 is stretched to the size of the measured object, a nut above the vernier caliper is screwed down to lock the position of the auxiliary ruler. The frame rod 7 in the groove of the right auxiliary ruler 10 is pushed to move towards the long rod 2, and after the rolling body 5 contacts the bottom of the sliding groove 4 after entering the sliding groove 4 (in line contact), the rolling body 5 stops moving (the rolling body 5 pushes the bottom of the sliding groove 4), and the nut 9 is screwed down. The center point of the marking head 6 is the middle point, the vernier caliper is dragged in the reciprocating longitudinal direction, and the trace marked on the measured object by the center point of the marking head 6 is the central line.
