As Fig. 1-shown in Figure 6, a kind of reisilometer that is provided with transparent outer cover, this reisilometer comprise housing parts and movement parts two parts of being located in it constitute; Described movement parts comprise compression spring 13, hook 22, hook spring 23, guide flange 14, centre pilot 8, elastic hammer 19, elastic tension spring 4, elastic stem 1 and buffer spring 24; Sheathed elastic tension spring 4 on the described centre pilot 8, guide flange 14 is connected with hook 22 with hook spring 23 with centre pilot 8 tops; Elastic hammer 19 is assembled with the elastic tension spring 4 that its top is provided with; The elastic hammer 19 of elastic stem 1 corresponding bottom is arranged at centre pilot 8 upper ends with one heart and connects into core section; It is characterized in that described housing parts is transparence, comprise transparent nut 21, transparent shell top 3, transparent shell bottom 18 and transparent tail-hood 12; Described transparent shell bottom 18 1 sides are provided with rule 6 and needle pivot 7, and corresponding rule 6 is respectively equipped with fixed block 5 up and down and reaches fixed block 11 down, and rule 6 is provided with the indicator slide block 10 that is mated; Transparent shell bottom 18 upper end screw threads are connected with transparent shell top 3, form cylinder assembly; With the movement that the assembles cylinder assembly of packing into, first-class semicircle jump ring 2 is with transparent nut 21 location that is threaded with transparent shell top 3; The compression spring 13 of packing into; Transparent tail-hood 12 forms one with the assembling that is threaded of 18 lower ends, transparent shell bottom.
Be between described transparent nut 21, transparent shell top 3, transparent shell bottom 18, the transparent tail-hood 12 and be threaded.
Described transparent shell bottom 18 is an integral body with feather key 20, need not any mechanical connection.
Described transparent shell bottom 18 is an integral body with last fixed block 5 and following fixed block 11, need not any mechanical connection.
This instrument is made up of two parts, and promptly transparent housing parts and core section below describe number of assembling steps in detail:
(1) core section:
A. guide flange 14 links together with centre pilot 8;
B. elastic hammer 19 fits together with elastic tension spring 4;
C. elastic stem 1 and buffer spring 24 are connected to form core section with said modules.
(2) housing parts:
A. index system: go up fixed block 5, needle pivot 7, indicator slide block 10, fixed block 11, rule 6 are formed index systems with transparent shell bottom 18 down;
B. transparent shell top 3 is threaded with transparent shell bottom 18, consists of cylindrical shell and treats general assembly.
The complete machine assembling:

B. the compression spring 13 of packing into;
C. transparent tail-hood 12 is threaded with transparent shell bottom 18, and final assembly is all finished.
In testing process, at first reisilometer utilizes spring to drive elastic hammer, produce instantaneous elasticity distortion restoring force behind the elastic stem attack concrete surface, and drive pointer resilience campaign, pointer accurately detects the resilience displacement, and on rule, indicate rebound value, through the correlation computations formula, and then detect concrete compressive strength.This instrument is used for the Non-Destructive Testing of xoncrete structure or member compressive strength, is widely used in the work progresss such as building operation, municipal works and construction of road and bridge.
Principle of work:
(1) returns Z-operation
Transparent reisilometer elastic stem 1 is withstood the concrete test surfaces, the transparent tail-hood 12 of light pressure, location hook pin 15 is thrown off guide flange 14 and is slowly lifted instrument, under compression spring 13 effects, elastic stem 1 stretches out, hook 22 hangs up with elastic hammer 19, and guide flange 14 drives pointer to zero-bit with indicator slide block 10 simultaneously, and promptly red groove overlaps with rule 6 zero lines on the indicator slide block 10.
(2) reisilometer obtains the energy operation
The elastic stem 1 that has stretched out is aimed at measuring point on the concrete test surfaces, evenly slowly push reisilometer, elastic stem 1 is pressed into reisilometer, and elastic tension spring 4 stretches; When instrument was pressed to certain position, elastic tension spring 4 elongations reached specified standard length 75mm, and this moment, instrument obtained nominal function 2.207N.m, and elastic hammer 19 is in hairtrigger state.This operating process should remain the reisilometer axle center perpendicular to test surfaces, must guard against pushing and overexerts excessive velocities.
(3) attack operation
Be right after aforesaid operations and continue the pushing reisilometer, under elastic tension spring 4 pulling force effects, elastic hammer 19 rapidly impacts to elastic stem 1 along centre pilot 8, kinetic energy will decompose in the hammer stem impact moment: part energy makes concrete produce plastic yield and is absorbed, and another part makes concrete produce elastic deformation and bullet makes its rebound for elastic hammer 19.
(4) read the rebound value operation
When elastic hammer 19 collides rebound for the first time with elastic stem 1 collision back, indicator slide block 10 is driven pointer and after this continue to push down reisilometer, and read rebound value from the pairing chi groove of reading of indicator slide block 10 grooves to certain position (by spring leaf 9); More than be an attack test operating procedure, and obtain the rebound value of a measuring point; Repeat the aforesaid operations process and just can obtain needed measuring point rebound value.
Above-mentioned with reference to embodiment to the detailed description that the reisilometer that is provided with transparent outer cover carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
