Abstract
The utility model discloses a pair of specimen pliers applied to a metal tension test at room temperature. The specimen pliers comprise a left pliers body, a right pliers body, a left spring sheet and a right spring sheet, wherein the left pliers body and the right pliers body respectively comprise a connecting part with a hinge hole in the middle part and a handle at the tail part; the connecting parts of the left pliers body and the right pliers part are connected by a rivet pin inserted into the hinge holes after being assembled and then the left pliers body and the right pliers part swing relatively by taking the rivet pin as a shared rotary shaft; the tail parts of the left spring sheet and the right spring sheet are fixed on the inner side surfaces of the rear parts of the handles of the left pliers body and the right pliers body in one-to-one correspondence by rivets; the head parts of the left spring sheet and the right spring sheet are positioned between the middle parts of the handles of the left pliers body and the right pliers body and are movably connected, so that the left spring sheet and the right spring sheet are connected in a V shape; the head parts of the left pliers body and the right pliers body are symmetrical inferior arc plates, so that the head parts of the left pliers body and the right pliers body which are closed together form an oval hole-shaped pliers nozzle. The specimen pliers provided by the utility model have the characteristics of stability in clamping, safety, reliability, convenience, practicability and simple structure.
Description
Technical field
The utility model relates to a kind of instrument, is specifically related to a kind of assay pliers of metal tensile test at room temperature.
Background technology
Metal, in carrying out tensile test at room temperature, be put into the sample of different length the hydraulically operated fixture up and down of testing machine.For short sample, in handling clamping sample process, often can there is security incidents such as " tongs ".Due to the deadweight of test button and the impact of shape, traditional pliers uses and is not very convenient.On the manufacturer of metal current material stretch test machine and market, there is no special-purpose assay pliers.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of assay pliers of metal tensile test at room temperature is provided, and it has stable, safe and reliable, convenient and practical, the simple in structure feature of clamping.
The purpose of this utility model is achieved in that a kind of assay pliers of metal tensile test at room temperature, comprise left and right caliper, this left and right caliper comprises respectively the connecting portion with hinge hole at middle part and the handle of afterbody, connects and take this rivet pin as relative swing of common rotating shaft work after the connecting portion of this left and right caliper is equipped with by a rivet pin interting in described hinge hole; Described assay pliers also comprises left and right spring leaf, the afterbody of this left and right spring leaf is fixed on the posterior medial face of handle of described left and right caliper correspondingly by rivet respectively, the head of this left and right spring leaf is between the middle part of the handle of described left and right caliper and be flexibly connected, and makes the connection that is in the shape of the letter V of left and right spring leaf; The head of described left and right caliper is symmetrical bad arc, and when described left and right caliper is closed up, head is flat round hole clamp mouth.
The assay pliers of above-mentioned metal tensile test at room temperature, wherein, the top end face of described left/right spring leaf is offered a groove, the head of described right/left spring leaf be provided with one with the plush copper of groove adaptation, the mode that the head of left and right spring leaf inserts groove with plush copper is connected.
The technical scheme of the assay pliers of metal tensile test at room temperature of the present utility model, eliminated in tension test process and clamped caused potential safety hazard, having stable, safe and reliable, convenient and practical, the simple in structure feature of clamping, is a kind of special-purpose sample clamp that has very much actual application value.
Accompanying drawing explanation
Fig. 1 is the stereographic map of the assay pliers of metal tensile test at room temperature of the present utility model;
Fig. 2 is the structural representation of the assay pliers of metal tensile test at room temperature of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, below by specific embodiment, be also described in detail by reference to the accompanying drawings.
Refer to Fig. 1, the assay pliers of a kind of metal tensile test at room temperature of the present utility model, comprises left and right caliper 1,2 and left and right spring leaf 3,4, wherein:
The middle part of left and right caliper 1,2 is provided with the connecting portion with hinge hole, connects and take this rivet pin 5 as the swing relatively of common rotating shaft do after the connecting portion of this left and right caliper is equipped with by a rivet pin 5 interting in hinge hole;
The head of left and right caliper 1,2 is for symmetrical bad arc and have certain width, and when left and right caliper is closed up, head is flat round hole clamp mouth 10;
The afterbody of left and right caliper 1,2 is handle;
The top end face of left spring sheet 3 or right spring leaf 4 is offered a groove, the head of right spring leaf 4 or left spring sheet 3 be provided with one with the plush copper of groove adaptation; The afterbody of left and right spring leaf 3,4 is fixed on the posterior medial face of handle of left and right caliper 1,2 correspondingly by two rivets 6 respectively, the head of this left and right spring leaf 3,4 connects between the middle part of the handle of left and right caliper 1,2 and in the mode that plush copper is inserted groove, makes the connection that is in the shape of the letter V of left and right spring leaf 3,4.
The jaw 10 of the assay pliers of metal tensile test at room temperature of the present utility model consists of the bad arc of certain width, can accurately clamp the circular column draft test bar within the scope of certain length.Left and right spring leaf 3,4 is given power of opening of handle of left and right caliper 1,2 all the time with lever principle simultaneously, makes the jaw 10 of assay pliers keep certain holding force, makes sample holder stable, safe and reliable.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
