Abstract

The utility model discloses a piezoelectric pipe pressure measuring clamp improved structure, which is invented for solving the problems of inconvenient use and the like in the prior art. The piezoelectric pipe pressure measuring clamp improved structure comprises a fixed clamp block, two screw rods, a movable clamp block and two locking screw caps; the fixed clamp block is provided with a V-shaped clamp opening; a piezoelectric sensing part is arranged at the position of the clamp opening; the two screw rods are respectively correspondingly fixed onto the positions of two sides of the fixed clamp block; a pivot hole and a rod groove are arranged on the upper portion of the movable clamp block; the movable clamp block is sleeved on one screw rod according to the pivot hole and can pivotally rotate correspondingly to the fixed clamp block; the other screw rod is contained inside the rod groove; another V-shaped clamp opening corresponding to the V-shaped clamp opening of the fixed clamp block is arranged on the movable clamp block; another piezoelectric sensing part is arranged inside the clamp opening; and the two locking screw caps are correspondingly screwed to the free ends of the screw rods. As the movable clamp block can pivotally rotate correspondingly to the fixed clamp block, the structure is extremely convenient in the operation of placing or taking out a to-be-measured oil pipe. In addition, the arrangement of the V-shaped clamp openings is favorable for clamping and measuring oil pipes with large pipe diameters.

Description

The piezoelectric type pipe is pressed the measured material structure-improved

Technical field

The utility model relates to a kind of piezoelectric type pipe and presses the measured material structure-improved, and especially a kind of energy is fixedly seized the device that oil pipe further passes through piezoelectric element measuring tube wall pressure power on both sides by the arms.

Background technology

As Fig. 6, shown in Figure 7, it is with in two separation that the piezoelectric type pipe of prior art is pressed measured material, following fixture block 91, be sheathed on to 92 corresponding foldings on the two parallel straight screw rod spares 93, and in straight screw rod spare 93 be provided with two nuts 931 as spacing fixing on, following

fixture block

91,92 move the assembly of usefulness, and on, following

fixture block

91,92 corresponding edge is provided with an arc notch 911,921, for oil pipe to be measured is located in wherein, and in arc notch 911,921 places are provided with the made piezoelectricity induction pieces 94 of piezoelectric, when the oil pipe of delivering oil is located in arc notch 911, after in 921, can experience the tube wall contraction of this oil pipe and then oil pressure is converted to voltage for measurement according to piezoelectricity induction pieces 94, and can quantize and present force value, be that a kind of having popularized applies to the technological means that automobile-used engine oil pipe pressure measures.

Above-mentioned structure is on reality is used, when the caliber of oil pipe to be measured is big, because the arc notch 911,921 on two

fixture blocks

91,92 has fixing curvature, and can only corresponding contact last lower edge to oil pipe, the distribution of contact point is not good, on measuring, lose precisely, in addition, because 91,92 of two fixture blocks only can be to split up and down as opening ways, therefore the action when changing oil pipe quite bothers, must earlier nut 931 be outwarded winding and then will go up fixture block 91 and move then and can insert or remove oil pipe, in operation, have the convenience defect of insufficient.

The utility model content

In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of easy to operate piezoelectric type pipe to press the measured material structure-improved.

In order to achieve the above object, piezoelectric type pipe of the present utility model is pressed the measured material structure-improved, includes:

Certain fixture block, be provided with a V-shape breach in described middle section of deciding the fixture block sandwich serface, be respectively equipped with the made piezoelectricity sense part of piezoelectric on two skew wall faces of described V-shape breach, described two piezoelectricity sense parts are provided with a V-shape fixed block and form V-type folder mouth on described V-shape fixed blocks;

The corresponding respectively place, both sides that decides fixture block of being fixed in of two screw rods, described two screw rods, described two screw rods be arranged in parallel and the free end of screw rod passes and the described relatively sandwich serface of deciding fixture block extends upward;

One moving fixture block, run through corresponding to a screw rod place on the described moving fixture block and be provided with a pivot hole, and be provided with a bar groove corresponding to the recessed moulding of the outside wall surface at another screw rod place, wherein said moving fixture block is located on the screw rod according to the pivot borehole jack and can corresponding describedly decide the fixture block pivot, and another screw rod is placed in the described bar groove, in addition, be provided with a V-shape breach in the middle section of described moving fixture block sandwich serface, be respectively equipped with the made piezoelectricity sense part of piezoelectric on two skew wall faces of described V-shape breach, described two piezoelectricity sense parts are provided with a V-shape fixed block and formation one and the described V-type folder mouthful corresponding V-type folder mouth of deciding fixture block on described V-shape fixed block;

Two locking nuts, described two locking nut correspondences are located on the free end of described screw rod.

Particularly, decide fixture block both sides places and run through respectively and be provided with screw, and described screw rod wears with an end correspondence respectively and is fixed in the described screw described.

Wherein, described piezoelectricity sense part coheres respectively on the V-shape breach that is fixedly installed on described fixed, the moving fixture block, and described V-shape fixed block coheres and is fixedly installed on the described piezoelectricity sense part.

Above-mentioned structure, this is created when using and pivots because can corresponding decide fixture block in moving fixture block, therefore when the user in the time will putting or take out oil pipe to be measured, can need not earlier moving fixture block then to be taken off in the dismounting of two locking screws down, only need according to deciding the fixture block pivot by moving the fixture block correspondence, and the purpose that can reach fast and put or take out expediently oil pipe, in operation, has quite high convenience, in addition, because it is fixed, the folder mouth of establishing with V-shape on the moving fixture block carries out the clamping of corresponding oil pipe, therefore the folder mouth has the beveled of wide-angle, therefore can be when correspondence be applicable to the oil pipe with big caliber, comparatively disperse because of seizing contact point on both sides by the arms, and reduce because of measure contact point branch position not good when measuring the defective of misalignment.
