Abstract
Description
Technical Field
[0001] This application relates to the technical field of Leeb hardness testers, and in particular to a Leeb hardness tester for building inspection. Background Technology
[0002] The Leeb hardness tester is a testing instrument. Its principle is based on the development of single-piece technology. In 1978, Dr. Leeb of Switzerland first proposed a brand-new method for measuring hardness. Its basic principle is that an impactor with a certain mass impacts the surface of the sample under a certain test force. The impact velocity and rebound velocity at a distance of 1 mm from the sample surface are measured. Using electromagnetic principles, a voltage proportional to the velocity is induced.
[0003] In existing technology, Leeb hardness testers typically include a tester body and an impact device connected by a wire. The lower end of the impact device is placed against the surface of the object to be tested. One hand holds the lower end of the impact device upright while the other hand presses it down. In some relatively narrow testing environments, it is not easy to hold the lower end of the impact device upright, making the operation inconvenient. At the same time, the reliability of the test results is difficult to guarantee, so further improvements are needed. Utility Model Content
[0004] To address the above problems, this application provides a Leeb hardness tester for building inspection.
[0005] This application provides a Leeb hardness tester for building inspection, which adopts the following technical solution:
[0006] A Leeb hardness tester for building inspection includes a tester body and an impact device connected to the tester body via a wire. The impact device is provided with an auxiliary component, which includes a mounting ring coaxially sleeved on the outer surface of the impact device, a plurality of mounting rods arranged around the axis of the mounting ring, and a suction cup disposed on the mounting rods. The suction cup is adsorbed onto the surface of the object to be tested.
[0007] By adopting the above technical solution, the suction cup adheres to the object to be tested, making it suitable for some narrow testing environments. This allows for temporary fixation of the lower end of the impact device. During use, the mounting ring can be straightened to further improve the stability of the impact device. Simultaneously, the adhesion between the suction cup and the surface of the object to be tested ensures the stability of the impact device during the testing process, thereby improving the reliability of the test results.
[0008] Preferably, the outer peripheral wall of the mounting ring is provided with anti-slip texture.
[0009] By adopting the above technical solution, the anti-slip texture on the outer peripheral wall of the mounting ring can increase the friction between the hand and the mounting ring, thereby making the mounting ring more secure during operation, reducing the risk of slipping, and improving the convenience and stability of operation.
[0010] Preferably, the auxiliary component is detachably connected to the impact device.
[0011] By adopting the above technical solution, the auxiliary components are detachably connected to the impact device, allowing them to be installed or removed according to actual testing needs. This design not only facilitates operation in different testing environments but also improves the applicability and flexibility of the equipment.
[0012] Preferably, the outer peripheral wall of the impact device is fixedly sleeved with a fixing ring, the mounting ring is coaxially sleeved on the fixing ring, and the mounting ring is provided with a fixing member for fixing with the fixing ring.
[0013] By adopting the above technical solution, the setting of the fixing ring provides a stable mounting base for the mounting ring, enabling the mounting ring to be accurately coaxially fitted onto the outer surface of the impact device, thereby ensuring the overall stability of the auxiliary components.
[0014] Preferably, the fixing ring is provided with a sleeve, the sleeve is coaxially sleeved on the impact device, the sleeve has a moving space for the impact device to slide along its own length direction, the mounting ring slides along the height direction of the sleeve, and the sleeve is provided with a first limiting member to restrict the sliding of the mounting ring.
[0015] By adopting the above technical solution, the sleeve design allows the mounting ring to slide along the height of the sleeve, thereby adjusting the position of the suction cup to accommodate test surfaces of different thicknesses, improving the applicability of the device. Simultaneously, the movement space within the sleeve allows the impact device to slide along its own length during testing, minimizing the impact on its normal operation.
[0016] Preferably, the mounting rod is a telescopic rod, which includes several folded sections and a second connector for connecting two folded sections. The second connector includes a sleeve and a tube respectively disposed on the folded sections, and an elastic rope. The tube is used to slide and insert into the sleeve. The two ends of the elastic rope are respectively connected to the inner walls of the sleeve and the tube. The elastic force of the elastic rope forces the tube to slide and insert into the sleeve.
[0017] By adopting the above technical solution, the mounting rod is designed as a telescopic rod, which effectively shortens its length, facilitating operation in confined spaces and improving the convenience of testing. The combined use of the sleeve and the insertion tube allows the mounting rod to quickly extend to the required length when needed, ensuring the stability of the auxiliary component. The elastic rope automatically pulls the insertion tube back into the sleeve using its elasticity, avoiding the tedious manual adjustment and ensuring a tight connection between each section, thereby improving the reliability and operational efficiency of the entire auxiliary component.
[0018] Preferably, the detector body is provided with a connector for connecting the impact device to the detector body.
[0019] By adopting the above technical solution, the detector body and the impact device are connected by a connector, so that the impact device can be stably fixed on the detector body.
[0020] Preferably, the connector includes a first connecting strap disposed on the body of the detector, a first sub-hook and loop fastener disposed on the inner side of the free end of the first connecting strap, and a first female hook and loop fastener disposed on the outer peripheral wall of the impact device, wherein the first sub-hook and loop fastener are bonded together.
[0021] By adopting the above technical solution, the connector design enables rapid connection and separation between the detector body and the impact device, improving ease of use. Specifically, the first sub-hook and loop fastener on the first connecting strip is bonded to the first female hook and loop fastener on the outer peripheral wall of the impact device; this detachable connection method is simple to operate.
[0022] Preferably, the connector further includes a second sub-hook and loop fastener disposed on the outside of the free end of the first connecting strip and a second female hook and loop fastener disposed at the connection between the first connecting end and the detector body, wherein the second sub-hook and loop fastener are bonded to the second female hook and loop fastener.
[0023] By adopting the above technical solution, the second male hook and loop fastener and the second female hook and loop fastener of the connector are bonded together, which can further enhance the fixing effect of the first connecting strip on the impact device and prevent the impact device from loosening during use.
[0024] In summary, this utility model has the following beneficial effects:
[0025] 1. By setting auxiliary components including a mounting ring, mounting rod and suction cup on the impact device, the impact device can be stably adsorbed onto the surface of the object to be tested, which effectively solves the problem of the impact device being difficult to straighten in narrow spaces and improves the ease of operation;
[0026] 2. The suction cup design of the auxiliary components ensures a stable connection between the impact device and the object to be tested, reducing the interference of external factors on the testing process and thus improving the reliability of the test results;
[0027] 3. The structural design of the mounting ring makes it easy for the operator to hold or fix it, and the anti-slip texture further enhances the stability during operation and optimizes the overall user experience. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.
[0036] This application discloses a Leeb hardness tester for building inspection.
[0037] Example 1:
[0038] A Leeb hardness tester for building inspection, as shown in the figure, includes a tester body 1 and an impact device 12 connected to the tester body 1 via a wire 11. An auxiliary component 2 is detachably connected to the impact device 12. Specifically, the auxiliary component 2 includes a mounting ring 21 coaxially sleeved on the outer surface of the impact device 12, a plurality of mounting rods 22 arranged around the axis of the mounting ring 21, and a suction cup 23 fixedly connected to the mounting rods 22. The upper end of the mounting rod 22 is fixedly connected to the lower surface of the mounting ring 21. The suction cup 23 is adsorbed onto the surface of the object to be tested, which is suitable for some relatively narrow environments where it is inconvenient to hold the impact device 12 by hand.
[0039] The mounting ring 21 can be made of metal, such as stainless steel or aluminum alloy, to ensure its structural strength and durability. Alternatively, it can be made of engineering plastic. Furthermore, to allow operators to grip the mounting ring 21 more securely during operation, reducing the risk of slippage and improving ease and stability, in this embodiment, the mounting ring 21 is provided with anti-slip texture 211. The anti-slip texture 211 can be a raised texture design, such as a diamond grid or stripes, to increase friction when gripping the hand.
[0040] In this embodiment, the upper end of the mounting rod 22 is fixedly connected to the lower surface of the mounting ring 21. There are two mounting rings 21, and correspondingly, there are also two suction cups 23.
[0041] In the installation of the mounting ring 21 and the impact device 12, the outer peripheral wall of the impact device 12 is fixedly sleeved with a fixing ring 13, and the mounting ring 21 is coaxially sleeved on the fixing ring 13. The mounting ring 21 is provided with a fixing member 131 for fixing with the fixing ring 13. In this embodiment, the fixing member 131 is a fixing bolt, which passes through the mounting ring 21. The fixing ring 13 is provided with a threaded hole 14 for threaded connection of the fixing bolt.
[0042] Furthermore, to facilitate adaptation to detection points of different depths, in this embodiment, as shown in the figure, a sleeve 15 is provided on the fixing ring 13. The sleeve 15 is coaxially sleeved on the impact device 12. The sleeve 15 has a space within it for the impact device 12 to slide along its length. The mounting ring 21 slides along the height direction of the sleeve 15. The sleeve 15 is provided with a first limiting member that restricts the sliding of the mounting ring 21; the first limiting member is a fixing member 131. A threaded hole 14 is provided on the outer surface of the sleeve 15. By providing the sleeve 15, the position of the suction cup 23 can be adjusted to adapt to surfaces of different thicknesses of the object to be tested, improving the applicability of the device. Furthermore, mounting rods 22 of different lengths can be replaced to accommodate different hand pressures applied to the mounting ring 21.
[0043] After use, to facilitate the storage of the impact device 12, in this embodiment, the detector body 1 is provided with a connector 3 for connecting the impact device 12 to the detector body 1. The connector 3 specifically includes a first connecting band 31 on the detector body 1, a first sub-hook and loop fastener 32 on the inner side of the free end of the first connecting band 31, a first female hook and loop fastener 33 on the outer peripheral wall of the impact device 12, a second sub-hook and loop fastener 34 on the outer side of the free end of the first connecting band 31, and a second female hook and loop fastener 35 at the connection between the first connecting end and the detector body 1. The first sub-hook and loop fastener 32 are bonded to the first female hook and loop fastener 33, and the second sub-hook and loop fastener 34 is bonded to the second female hook and loop fastener 35.
[0044] The implementation principle of a Leeb hardness tester for building inspection according to an embodiment of this application is as follows: the suction cup 23 adheres to the object to be tested, which can be adapted to some narrow testing environments to temporarily fix the lower end of the impact device 12. During use, the mounting ring 21 can be straightened to further improve the stability of the impact device 12. At the same time, the adsorption between the suction cup 23 and the surface of the object to be tested ensures the stability of the impact device 12 during the testing process, thereby improving the reliability of the test results.
[0045] Example 2:
[0046] Reference Figure 5 , Figure 6 The difference from Embodiment 1 is that in this embodiment, the mounting rod 22 is a telescopic rod. The telescopic rod includes a first rod 4 connected to the mounting ring 21, a second rod 5 slidably sleeved on the first rod 4, and a second limiting member 6 that restricts the sliding of the second rod 5. In this embodiment, the second limiting member 6 includes a limiting rod 61, a limiting spring 62 coaxially sleeved on the limiting rod 61, and a force-applying block 63 fixedly connected to the limiting rod 61. The limiting rod 61 slidably passes through the second rod 5. The first rod 4 has limiting holes, which are spaced apart along the height direction of the first rod 4. The two ends of the spring 62 are fixedly connected to the surfaces of the second rod 5 and the force-applying block 63 that are close to each other. The spring 62 forces the limiting rod 61 to move towards the limiting holes.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
