Abstract
A wall-hanging Young's modulus measuring instrument is composed of pulley, fixing plate, inserted in or hung from wall, bare lever and its supporting plate, clamping head, steel wire, plate for fixing the end of steel wire and hook of poise weight. Its advantages are high verticality, high stability, and less occupied space.
Description
The invention belongs to the physical experiment apparatus technical field, is that a kind of critical piece with measuring instrument all adopts the mode of insert hanging to be fixed on wall-hanging modulus measurer on the wall.
The structure of present known modulus measurer all is two column stent-types.The subject matter of this structure be instrument vertically the degree operation that is difficult to guarantee, add and subtract counterweight make easily that support rocks, steel wire to be measured vibration, the effective length of steel wire to be measured is not only too short, and measurement inconvenience, image observation inconvenience, the complex structure of support, the installing/dismounting trouble, the support floor area is too big, be not easy to the instrument keeping, make the laboratory utilization factor not high.(patent No.: ZL02275844.5) " reversely hung Yong's modulus measurer " is though the effective length of the steel wire to be measured that increased substantially in the invention of application on July 25th, 2002 in Sichuan University, and make measurement of length, image observation all become convenient, and can partly eliminate the vibration of the steel wire that causes because of the plus-minus counterweight but above-mentioned other problem is still unresolved.
The purpose of this invention is to provide a kind of wall-hanging modulus measurer, the vertical degree of instrument is guaranteed, eliminate the vibration with steel wire of rocking of support, simplify apparatus structure, reduce manufacturing cost, make installation, convenient disassembly, be convenient to the instrument keeping, reduce instrument significantly and take up an area of and raising laboratory utilization factor.
The object of the present invention is achieved like this: line location on wall, to insert and hang fixed head and be screwed to make on the wall and form a seam between plate and the metope, end at pulley, optical lever support plate, steel wire head fixed plate has a bending, successively their bending part is inserted then and hung in the seam, again the end of steel wire is played a brief summary, its other end is passed steel wire head fixed plate from bottom to top, chuck and optical lever fixed head, link to each other with the counterweight hook after walking around pulley, at last optical lever is placed on the optical lever support plate.Instrument when finish needing dismounting, take off steel wire earlier after, pulley, optical lever support plate and steel wire head fixed plate are got final product from inserting to hang to extract out the fixed head.
Owing to adopt such scheme, can receive following remarkable result:
1, because the vertical degree of metope is reliably guaranteed, thereby the vertical degree that can be steel wire is established a basis reliably; This vertical degree compared with traditional two pillar constructions only relies on naked-eye observation, and it is much accurate, and has saved the adjusting program of vertical degree.
2, because traditional two high column structures are a kind of " tall and thin " bodily forms, poor stability, the operation of plus-minus counterweight easily causes the vibration with steel wire of rocking of shelf, replaces column with body of wall now, and its stability is natural can be improved greatly.
3, original structure is made of the parts more than 13 kinds, and weight is all more than 20kg, and this programme only needs 8 kinds of parts and simple in structure, the not enough 10kg of its general assembly (TW), thus can reduce cost significantly.
4, because the installation of traditional structure, the dismounting difficulty is big, thus in a single day load onto, even for a long time need not, can be with its dismounting keeping yet, thereby be difficult to realize dustproof, antirust purpose, and this programme except that three insert hang fixed heads need fix need not take off on the wall, remaining part can be easily, need not can take off by any instrument, put into a boxes, thereby reach well dustproof, rust-proof effect.
5, in the original structure, because a pedestal of more than ten kilogram of weighing is arranged at the bottom, and lateral dimension is very big, this just must account for a large amount of ground and space, cause the laboratory congested, if having one period need not, the wasting of resources is caused in can account for again storeroom a large amount of ground and space.This programme does not then take up an area of fully, shared insufficient space original 1/10th, this not only can improve the laboratory congestion phenomenon greatly, also provides convenience for storeroom.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a front view of the present invention;
Fig. 2 is its left view;
Fig. 3 is a pulley;
Fig. 4 is the side view cross section of optical lever support plate;
Fig. 5 inserts front view and the vertical view of hanging fixed head;
Fig. 6 is the lateral sectional view of steel wire head fixed plate;
Among the figure, 1, pulley 2, insert to hang fixed head 3, optical lever 4, optical lever support plate 5, chuck 6, steel wire 7, steel wire head fixed plate 8, counterweight hook
Embodiment:
Line is made three and is inserted the position that hangs fixed head (2) on the wall earlier, it is fixing on the wall to insert the extension fixed head with screw, again with pulley shown in Figure 3 (1), the left side bending part of optical lever board (4) shown in Figure 4 and steel wire head fixed plate (7) shown in Figure 6 inserts respectively in the slotting extension fixed head (2) shown in Figure 5, after the end of steel wire (6) is played a brief summary, its head passes in the hole of steel wire head fixed plate, after passing through chuck (5) and optical lever fixed head (4), walk around pulley (1) and link to each other with the counterweight hook, and on hook, add the part counterweight in advance and make steel wire stretching, go up at optical lever support plate (4) at last and place optical lever and get final product.
Claims (2)
1, a kind of wall-hanging modulus measurer, constitute by pulley, plug in fixed head, optical lever, optical lever support plate, chuck, steel wire, steel wire head fixed plate and the counterweight hook hung, it is characterized in that: pulley, optical lever support plate, steel wire head fixed plate are all inserted to hang over to insert and are hung on the fixed head, insert the extension fixed head and then are screwed on the wall.
2, wall-hanging Young pattern flowmeter according to claim 1, it is characterized in that: an end of pulley, optical lever support plate and steel wire head fixed plate has bending.After the instrument assembling finished, bending part is in to be inserted in the crack of hanging fixed head and metope formation.
