Description

Technical Field

[0001] The utility model belongs to the technical field of rebound hammers, and particularly relates to a rebound hammer calibration guide device. Background Art

[0002] In the field of construction engineering, concrete strength testing is a very important task. As a commonly used concrete strength testing tool, the rebound hammer has a decisive impact on the quality of the project due to its accuracy and reliability. The rebound hammer evaluates the hardness and strength of concrete by firing a projectile at the concrete surface and measuring its rebound height.

[0003] However, existing rebound hammers have some problems during use. In particular, when hitting a wall, due to manual control errors of the operator, it is difficult to ensure that the rebound hammer and the wall are always perpendicular. This will lead to deviations in the measurement results and affect the accuracy of the calibration effect.

[0004] For example, when using a traditional rebound hammer, the operator needs to manually adjust the instrument angle to ensure verticality. However, this adjustment is often imprecise and easily affected by the operator's experience and visual judgment. In addition, the unevenness of the wall surface can also make vertical alignment difficult. In actual operation, due to the influence of these factors, the measurement results of the rebound hammer often have certain errors, which not only affects the accurate assessment of concrete strength, but may also lead to misjudgment of project quality.

[0005] To solve the above problems, some auxiliary guiding devices have appeared on the market, aiming to help operators align the wall more accurately. However, these auxiliary devices are usually complex in structure and high in cost, and still have certain limitations in actual use, such as poor adaptability in narrow spaces or irregular surfaces.

[0006] Therefore, there is an urgent need for a guide device that has a simple structure, low cost and can effectively improve the calibration accuracy of the rebound tester. Utility Model Content

[0007] The utility model aims to provide a rebound hammer calibration guide device, which can ensure that the rebound hammer is always in a vertical state when hitting the wall, thereby significantly improving the accuracy and reliability of concrete strength detection.

[0012] One of the guide assemblies includes a first connecting column installed inside the fixed tube on one side, a first fixing block is fixed to the end of the first connecting column away from the fixed tube on this side, two first abutment frames are slidably connected inside the first fixing block, and the two first abutment frames are arranged parallel to the through groove of the mounting ring;

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, a rebound hammer calibration guide device includes a mounting ring 1. A through slot is provided in the middle of the mounting ring 1 for mounting a rebound hammer. The rebound hammer is mounted on the inner side of the mounting ring 1. The rebound hammer can be guided by the guide assembly described below so that the rebound hammer is always set at 90 degrees when in contact with the wall.

[0028] A fixing tube 2 is fixed on both sides of the mounting ring 1 , and a guide assembly is respectively installed on one end of the two fixing tubes 2 away from the mounting ring 1 .

[0029] Example 1:

[0030] Refer to the attached Figure 1 , both guide assemblies include a first connecting column 3 installed inside the fixed tube 2, a first fixing block 4 is fixed to the end of the first connecting column 3 away from the fixed tube 2, a first abutting frame 5 is slidably connected inside the first fixing block 4, and the first abutting frame 5 is arranged parallel to the through groove of the mounting ring 1;

[0031] When the rebound hammer is used, the two first abutment frames 5 can be in direct contact with the wall, so that the mounting ring 1 and the wall are parallel, and the rebound hammer and the wall are perpendicular at 90 degrees.

[0032] Example 2:

[0033] This embodiment makes the following improvements on the basis of embodiment 1:

[0034] Refer to the attached Figure 2-3 One of the guide assemblies includes a first connecting column 3 installed inside a fixed tube 2 on one side. A first fixing block 4 is fixed to the end of the first connecting column 3 away from the fixed tube 2 on this side. Two first abutment frames 5 are slidably connected inside the first fixing block 4, and the two first abutment frames 5 are arranged parallel to the through groove of the mounting ring 1.

[0035] Another guide assembly includes a second connecting column 6 installed inside the fixed tube 2 on the other side. A second fixing block 7 is fixed to the end of the second connecting column 6 away from the fixed tube 2 on this side. Two second abutment frames 8 are slidably connected to the interior of the second fixing block 7, and the two second abutment frames 8 are arranged perpendicular to the through groove of the mounting ring 1.

[0036] When measuring a wall near a corner, the second abutment frame 8 can be used to contact the side wall, while the first abutment frame 5 can be used to contact the front wall, so that the wall near the corner can be detected. Furthermore, the first connecting column 3 and the fixing tube 2, as well as the second connecting column 6 and the fixing tube 2, are fixedly connected by threads. Through this arrangement, the user can disassemble the first abutment frame 5 or the second abutment frame 8, so as to cope with different situations, such as replacing the first abutment frame 5 or the second abutment frame 8 when facing a flat wall or a wall near a corner.

[0037] Example 3:

[0038] The improvements made in this embodiment on the basis of Embodiment 1 and Embodiment 2 are as follows:

[0039] See Figure 4 As shown, a mounting groove 9 is provided inside the first fixing block 4 and the second fixing block 7 and at the position of the first abutting frame 5 and the second abutting frame 8. A spring 10 is installed inside the mounting groove 9. A connecting strip 11 is fixed inside the first abutting frame 5 and the second abutting frame 8 and is connected to the spring 10.

[0040] When the wall between the two first abutting frames 5 or the two second abutting frames 8 is uneven, the first abutting frame 5 or the second abutting frame 8 can first contact the wall. After the contact, the first abutting frame 5 or the second abutting frame 8 is compressed, and the spring 10 is compressed. If the wall between the two first abutting frames 5 or the two second abutting frames 8 is uneven, a measuring instrument 12 is installed on one of the first abutting frames 5 and one of the second abutting frames 8. The measuring instrument 12 can be a device such as a rangefinder. Through the setting of the measuring instrument 12, the change in the distance between the two first abutting frames 5 or the two second abutting frames 8 can be detected, so that the user can know whether the wall between the two first abutting frames 5 or the two second abutting frames 8 is flat. The other first abutting frame 5 and the other second abutting frame 8 are provided with scales. Through this setting, the measuring instrument 12 can more clearly capture the specific value of the wall flatness.

[0041] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
