TECHNICAL FIELD
[0001] The present application relates to the technical field of building engineering detection, and in particular to a rebound hammer. BACKGROUND
[0002] There are many types of rebound hammers currently used in the industry, but there are still some problems in general. For example: (1) the rebound hammers commonly used in the prior art all have the problem of uneven night vision, and the operation will be affected in insufficient light or dark environment; (2) the rebound hammers that can be used in insufficient light or dark environment mostly use LED lights, which need to be installed with batteries, so there will be the trouble of insufficient battery power and the need for charging. On the other hand, since the outdoor temperature is low in winter, the battery is usually not durable, so it will affect the progress of on-site operation. In addition, in order to save energy and reduce emissions, the use of batteries should also be minimized to avoid adverse effects on the environment; (3) when using the rebound hammer in the prior art for detection, the test angle is usually preliminarily determined by manual observation. Since manual observation usually has errors and is also highly dependent on the professional level of the operator, it is usually difficult to accurately determine whether the current test angle is horizontal or vertical by manual observation in actual application scenarios, which may cause the detection result to deviate from the actual value. CONTENT OF THE UTILITY MODEL
[0003] Therefore, the rebound hammer is provided, so that whether the test angle is horizontal or vertical can be accurately determined, and deviation of the detection result from the actual value is avoided as much as possible.
[0004] The technical scheme of the rebound hammer is implemented as follows:
[0005] A rebound hammer, comprising: a rebound hammer body and a shell;
[0006] The bottom of the shell is provided with a rear end cover;
[0007] The top of the shell is provided with a clamping spring;
[0008] The top of the clamping spring is provided with a front end cover; the front end cover is provided with a through hole;
[0009] The rebound hammer body is arranged in the interior of the shell; the rear end of the rebound hammer body is connected with the rear end cover; the front end of the rebound hammer body is connected with the clamping spring; the front end of the rebound hammer body is provided with a rebounding rod; the front end of the rebounding rod extends out of the through hole in the front end cover;
[0010] The leveling device is connected with the tail end of the leveling pointer.
[0011] The readout device is provided on the shell, and comprises a scale and an indicator.
[0012] Preferably, the leveling device is a weight.
[0013] Preferably, the scale is provided with a plurality of angle scales.
[0014] Preferably, the plurality of angle scales are 0°, 90°, -90° and -180°.
[0015] Preferably, the plurality of angle scales further comprise 30°, 45°, 60°, 120°, 135°, 150°, -30°, -45°, -60°, -120°, -135° and -150°.
[0016] Preferably, the indicator is a slider which is slidingly arranged on the scale.
[0017] Preferably, the scale is provided with a plurality of scale values.
[0018] Preferably, the readout device is provided with a transparent cover.
[0019] As can be seen from the above, in the rebound apparatus in the utility model, because the leveling device is arranged in the rebound apparatus, the test angle can be accurately judged to be horizontal or vertical through the leveling device before detection, so that deviation of the detection result from the actual value can be avoided as much as possible. In addition, because the scale and the leveling pointer of the leveling device are coated with a luminous coating, the scale and the leveling pointer will become bright even in a dark environment, so that the operator can confirm through the leveling device whether the test angle is horizontal or vertical. Furthermore, because the scale and the indicator of the readout device are also coated with a luminous coating, the operator can accurately read the detection data through the readout device even in a dark environment.

[0025] In order to make the technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and specific embodiments.
[0026] Figure 1 The structure diagram of the rebound hammer in the embodiment of the utility model is shown. As shown in Figure 2 The rebound hammer in the embodiment of the utility model comprises a rebound hammer body and a shell 14.
[0027] The bottom of the shell 14 is provided with a rear end cover 18.
[0028] The top of the shell 14 is provided with a clamping spring 13.
[0029] The top of the clamping spring 13 is provided with a front end cover 12; the front end cover 12 is provided with a through hole.
[0030] The rebound hammer body is arranged inside the shell 14; the rear end of the rebound hammer body is connected with the rear end cover 18; the front end of the rebound hammer body is connected with the clamping spring 13; the front end of the rebound hammer body is provided with a rebounding rod 11; the front end of the rebounding rod 11 extends out of the through hole in the front end cover 12.
[0031] The shell is provided with a leveler 15; the leveler 15 comprises a scale disc, a level pointer and a leveling device; the middle part of the level pointer is rotationally connected with the central shaft of the scale disc; the leveling device is connected with the tail end of the level pointer; the scale disc and the level pointer are both coated with a luminous coating.
[0032] The shell 14 is provided with a reading device; the reading device comprises a scale 17 and an indicator 16; the scale 17 is arranged along the extension direction of the rebound hammer body; the indicator 16 is movably arranged on the scale 17; the scale 17 and the indicator 16 are both coated with a luminous coating.
[0033] In the technical solution of the present application, when the rebound hammer is used for detection, the front end of the rebounding rod can be abutted against the surface of the object to be detected, and then the leveling device on the rebound hammer is used to confirm whether the test angle is horizontal (or vertical). For example, as shown in Figure 3 When the test angle is horizontal (i.e. the test angle α = 0°), the leveling pointer in the leveling device will point to the 90° or -90° scale line on the scale disc; and when the test angle is not horizontal, the leveling pointer in the leveling device will deviate from the 90° or -90° scale line on the scale disc. At this time, the test angle of the rebound hammer can be adjusted up and down until the leveling pointer points to the 90° or -90° scale line on the scale disc, so that the test angle can be ensured to be horizontal. For another example, as shown in Figures 2 to 5 When the test angle is vertical (i.e. the test angle α = 90° or α = -90°), the leveling pointer in the leveling device will point to the 0° or 180° scale line on the scale disc; and when the test angle is not vertical, the leveling pointer in the leveling device will deviate from the 0° scale line on the scale disc. At this time, the test angle of the rebound hammer can be adjusted left and right until the leveling pointer points to the 0° or 180° scale line on the scale disc, so that the test angle can be ensured to be vertical. After confirming that the test angle is horizontal (or vertical), the rebound hammer can be used for detection, and the detection data (for example, the rebound value indicated by the indicator in the reader) can be read by the reader to complete the corresponding detection.
[0034] As shown in Figure 1 Since the leveling device is provided in the rebound hammer of the present application, the test angle can be confirmed to be horizontal (or vertical) by the leveling device before detection, so that the deviation between the detection result and the actual value can be avoided as much as possible. In addition, since the scale disc and the leveling pointer of the leveling device are both coated with a luminous coating, the scale disc and the leveling pointer will become bright even in a dark environment, so that the operator can confirm whether the test angle is horizontal (or vertical) by the leveling device. Furthermore, since the scale 7 and the indicator 6 of the reader are also both coated with a luminous coating, the operator can accurately read the detection data by the reader even in a dark environment.
[0035] In addition, a snap spring is provided on the top of the shell, which can be used to fix the rebounding rod to prevent the rebounding rod from being unstable and from being detached from the rod during the operation of the rebound hammer.
[0036] In addition, in the technical solution of the present application, the rebound hammer can be realized by various specific implementation manners. The technical solution of the present application will be introduced in detail below by taking several specific ways as examples.
[0037] For example, as an example, in one specific embodiment of the present application, the leveling device can be a weight.
[0038] Since the middle part of the leveling pointer is rotationally connected with the central axis of the dial, the leveling pointer can rotate freely around the central axis of the dial; and since the tail end of the leveling pointer is connected with the weight, under the action of gravity, the weight can make the leveling pointer always point upwards along the direction of gravity, thereby pointing to the corresponding angle on the dial.
[0039] In addition, as an example, in one specific embodiment of the present application, a plurality of angle scales can be provided on the dial, so as to facilitate the operator to more accurately confirm whether the test angle is horizontal (or vertical), and further confirm the angle of deflection from the horizontal direction or the vertical direction.
[0040] For example, as an example, in one specific embodiment of the present application, the plurality of angle scales can be 0°, 90°, -90° and -180°, as shown in .
[0041] For another example, as an example, in one specific embodiment of the present application, the plurality of angle scales can also be 0°, 30°, 45°, 60°, 90°, 120°, 135°, 150°, 180°, -30°, -45°, -60°, -90°, -120°, -135° and -150°, so as to facilitate the operator to more accurately confirm whether the test angle is horizontal or vertical, and further confirm the angle of deflection from the horizontal direction or the vertical direction.
[0042] In addition, as an example, in one specific embodiment of the present application, the indicator 6 is a slider which is slidingly arranged on the scale 7.
[0043] In addition, as an example, in one specific embodiment of the present application, a plurality of scale values are provided on the scale, so as to facilitate the operator to more accurately read the detection data through the reader.
[0044] In addition, as an example, in one specific embodiment of the present application, a transparent cover is arranged above the reader, so as to provide certain protection for the reader, and does not affect the reading of the detection data.
[0045] In conclusion, in the technical scheme of the present application, since the leveling device is arranged in the rebound tester, the test angle can be accurately judged to be horizontal or vertical by the leveling device before detection, so that deviation of the detection result from the actual value can be avoided as much as possible. In addition, since the dial and the leveling pointer of the leveling device are coated with a luminous coating, the dial and the leveling pointer will be bright even in a dark environment, so that an operator can confirm whether the test angle is horizontal or vertical through the leveling device. Furthermore, since the scale and the indicator of the reader are also coated with a luminous coating, an operator can accurately read the detection data through the reader even in a dark environment.
[0046] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
