Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rebound hammers, in particular to a rebound hammer with a positioning function. Background Art
[0002] The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance. The instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).
[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: the common rebound tester is conical in shape. When in use, the instrument is held with both hands and pressed toward the detection point for detection. When holding, the rebound tester is easy to slip out of the hand due to the smooth surface. At the same time, it is not easy to position and keep it perpendicular to the detection surface, which affects the detection results. Summary of the invention

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example

[0028] The positioning assembly 3 includes a circular shell 31 which is sleeved on the rebound tester body 1, a shell cover 32 is installed at the open part of the circular shell 31 facing outward, three indicator light control components 36 are installed at equal intervals on the shell cover 32 facing outward, a pad 34 is installed at the top of the circular shell 31, three LED indicator lights 35 are installed on the top of the pad 34, and three clamping structures 37 are installed at equal intervals inside the circular shell 31, and a conductive block 38 is installed inside the mounting end of the clamping structure 37, and the conductive end of the indicator light control component 36 contacts the conductive block 38. Two batteries are also installed inside the circular shell 31, and the batteries are connected to the conductive block 38 and the LED indicator light 35 respectively through wires.
[0029] The indicator light control member 36 includes an internal threaded sleeve 365 installed on the shell cover 32, and a through hole communicating with the inside of the internal threaded sleeve 365 is opened at a position of the shell cover 32 facing the internal threaded sleeve 365. An external threaded sleeve 363 is installed on the internal thread of the internal threaded sleeve 365, and a cylinder 361 is installed on one side of the external threaded sleeve 363. A switch 362 is installed on the outside of the cylinder 361. A conductive rod 364 is installed at the power-on end of the switch 362, and the right end of the conductive rod 364 passes through the inside of the external threaded sleeve 363 and extends to the outside. The installation process of the indicator light control member 36 is as follows: first, the conductive rod 364 passes through the inside of the internal threaded sleeve 365. , and then screw the external threaded sleeve 363 into the interior of the internal threaded sleeve 365. At this time, the cylinder 361 is fixed on the shell cover 32, the conductive rod 364 is in contact with the conductive block 38 for electrical connection, the threaded connection between the external threaded sleeve 363 and the internal threaded sleeve 365, and the conductive rod 364 and the conductive block 38 are in contact and connected, so that the indicator light control component 36 is a detachable connection and a consumable component, which is convenient for replacement. The three indicator light control components 36 limit the position of the rebound tester from three directions, and the three positioning components 3 are conducive to making the rebound tester body 1 in a horizontal state without tilting, not easy to tilt, and it is easier to ensure that the rebound tester and the wall are in a vertical state.
[0030] After the conductive rod 364 contacts the conductive block 38 , the LED indicator 35 is in an off state. When an object contacts the switch 362 , the LED indicator 35 is turned on. When no object contacts the switch 362 , the LED indicator 35 is turned off.
[0031] During use, after the three indicator light control components 36 are installed, the machine is used by holding the handle 4 with both hands. By holding the handle 4 with both hands, when the impact rod 2 contacts the detection point, the continuous time and force will make the rebound tester body 1 move forward continuously, so that the impact rod 2 is retracted into the inside of the rebound tester body 1. When the impact rod 2 is completely retracted into the inside of the rebound tester body 1, the cylinder 361 and the switch 362 are also in contact with the detection surface at the same time. Press the switch 362 to control the corresponding LED indicator 35 to light up. If the three LED indicator lights 35 are all in a state of lighting up at the same time, it indicates the verticality of the rebound tester and the wall. Example
[0032] Reference Figure 1-6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0033] The abutting structure 37 includes an insulating sleeve 371 disposed inside the annular shell 31 , and the insulating sleeve 371 is movably disposed inside the annular shell 31 .
[0034] Side sliders 372 are installed on both sides of the outer wall of the insulating sleeve 371. A sliding hole is opened on the top of the side slider 372, and a T-bar 373 is slidably installed through the sliding hole. The bottom end of the T-bar 373 is installed inside the annular shell 31, and a spring 374 is sleeved on the outer wall of the T-bar 373.
[0035] Three threaded barrels 39 are installed at equal intervals inside the annular shell 31 . Fixing screws 33 are threadedly installed on the threaded barrels 39 . A through hole is formed through the annular shell 31 for the fixing screws 33 to pass through.
[0036] Rings 5 are sleeved on both sides of the outer wall of the rebound tester body 1, and a grip rod 4 is installed at the bottom of the ring 5. The grip rod 4 is held by both hands to use the machine. By holding the grip rod 4 with both hands, not only can the rebound tester body 1 be better held and not easily dropped, but also it is more convenient and stable to apply force to the rebound tester body 1.
[0037] During use, when the conductive rod 364 collides with the conductive block 38, the conductive rod 364 will apply rearward pressure to the conductive block 38, so that the insulating sleeve 371 drives the side slider 372 to move backward and compresses the spring 374. Under the elastic action of the spring 374, the insulating sleeve 371 will be pushed to move forward, thereby ensuring that the conductive block 38 and the conductive rod 364 are in precise contact to avoid poor contact.
