Description

Technical Field

[0001] This utility model relates to the field of torque testing technology, specifically a micro-drill resistance instrument for detecting internal damage to wooden components of ancient buildings. Background Technology

[0002] The micro-drill resistance meter is a professional testing instrument used to test the internal structural hardness and displacement relationship of wooden structures. It is mainly used in the fields of ancient buildings, ancient trees, precious timber, and wooden building construction.

[0003] The current on-site testing method for micro-drill resistance gauges involves manually holding the testing device and fixing its relative position to the component being tested. However, commonly used micro-drill resistance gauges are approximately 70-80cm long and weigh about 10-15kg. Relying solely on manual handling requires maintaining the instrument's stability and relative position for an extended period during testing. This not only significantly increases the workload for manual workers but also, due to human shaking and movement, can cause errors in data acquisition and even damage to the instrument.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a micro-drill resistance instrument for detecting internal damage to wooden components of ancient buildings, so as to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a micro-drill resistance instrument for detecting internal damage to wooden components of ancient buildings, comprising an instrument body, a support sleeve fitted at the front end of the instrument body, a support component on one side of the support sleeve, and the instrument body having a square cross-section.

[0009] Preferably, the support assembly includes a pair of fixing plates, which are respectively disposed on both sides of the support sleeve. A support plate is hinged between the pair of fixing plates. One end of the support plate is hinged between the fixing plates, and the other end is open and slidably connected to a support plate.

[0010] Preferably, the outer side of the first support plate is provided with a through groove, the second support plate is provided with a sliding column, the sliding column is slidably connected to the through groove, and the top of the sliding column is provided with a limiting plate.

[0011] Preferably, the slide column has threads on the side portion outside the through groove, and a knob is threadedly connected to the slide column.

[0012] Preferably, the outer side of the through groove is provided with a friction groove, the width of which is greater than the diameter of the knob.

[0013] (III) Beneficial Effects

[0014] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The micro-drill resistance instrument for detecting internal damage of wooden components in ancient buildings has a support sleeve on the outside of the instrument body. When detecting wooden components, the second support plate is pulled out from the first support plate and the first support plate is unfolded. The knob is tightened to fix the second support plate. The other end of the second support plate can abut against the wooden component to help support it. The entire weight of the instrument is no longer completely supported by the operator. The operator only plays an auxiliary support role. At the same time, the support sleeve can be horizontally fitted on the instrument body, making it more widely applicable.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model embodiment provides a micro-drill resistance instrument for detecting internal damage to wooden components of ancient buildings, such as... Figure 1-2 As shown, the instrument includes an instrument body 1, a support sleeve 2 is fitted on the front end of the instrument body 1, and a support component is provided on one side of the support sleeve 2. The cross-section of the instrument body 1 is square, so the support sleeve 2 can be rotated 90 degrees and fitted onto the instrument body 1. In some scenarios where the instrument body 1 needs to be placed horizontally, the support sleeve 2 can be rotated 90 degrees and fitted onto the instrument body 1 so that the support component can still function.

[0020] Reference Appendix Figure 1-2 The support assembly includes a pair of fixing plates 3, which are respectively disposed on both sides of the support sleeve 2. A support plate 4 is hinged between the pair of fixing plates 3. One end of the support plate 4 is hinged between the fixing plates 3, and the other end is open and has a support plate 5 slidably connected inside. When not in use, the support plate 5 is stored inside the support plate 4.

[0021] Reference Appendix Figure 1-2The support plate 4 has a through groove 41 on its outer side, and a sliding post 51 on the support plate 5. The sliding post 51 is slidably connected to the through groove 41, and a limiting plate 52 is provided at the top of the sliding post 51. The side of the sliding post 51 outside the through groove 41 is threaded, and a knob 6 is threaded onto the sliding post 51. The knob 6 cannot be dislodged from the sliding post 51 under the action of the limiting plate 52. The outer side of the through groove 41 has a friction groove 7. The surface of the friction groove 7 is rough, which increases the friction between the friction groove 7 and the knob 6. The width of the friction groove 7 is larger than the diameter of the knob 6. After the knob 6 is tightened, it is tightly attached to the friction groove 7, and the support plate 5 cannot slide. When the other end of the support plate 5 rests against the wooden component, the operator does not need to support the instrument body 1 with great force, but only needs to play an auxiliary fixing role.

[0022] This utility model discloses a micro-drill resistance instrument for detecting internal damage to wooden components of ancient buildings. A support sleeve is fitted on the outside of the instrument body. When testing the wooden component, the second support plate is pulled out from the first support plate and the first support plate is unfolded. The knob is tightened to fix the second support plate. The other end of the second support plate can abut against the wooden component, which can play a supporting role. The entire weight of the instrument is no longer entirely supported by the operator. The operator only plays an auxiliary supporting role. At the same time, the support sleeve can be fitted horizontally on the instrument body, which has a wider range of applications.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
