[0002] Non-destructive testing of concrete thickness is a method that uses non-destructive techniques such as ultrasound, electromagnetics, and impact echo to transmit specific physical signals into the concrete, receive and analyze the propagation and reflection patterns of the signals within the concrete, and then accurately calculate the thickness of the concrete component.

[0003] The existing technology has the following drawbacks: the existing concrete thickness non-destructive testing instrument lacks a dedicated gripping auxiliary structure. When the operator holds the instrument for a long time, the device is prone to slippage due to hand fatigue or insufficient friction between the hand and the detector. This may not only damage the instrument but also affect the continuity of the testing process. Therefore, a concrete thickness non-destructive testing device is proposed to solve the above problems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 This utility model provides an embodiment of a non-destructive testing device for concrete thickness, comprising a detector 1. The detector 1 receives raw signals from a test probe regarding concrete thickness, analyzes, calculates, and processes these signals to obtain concrete thickness data. A detection head 2 is located on the right side of the detector 1. The detection head 2 emits detection signals into the concrete and simultaneously receives feedback signals reflected and propagated within the concrete, providing raw data for subsequent thickness calculations. A movable block 3 is slidably connected to the outer wall of the detector 1. The movable block 3 primarily supports and connects the entire finger sleeve 4. The finger sleeve 4 is fixedly connected to the outer wall of the movable block 3. The finger sleeve 4 is made of existing elastic plastic material and can wrap around the fingers. A pull rod 5 is slidably connected through the inner wall of the movable block 3, allowing lateral movement of the insertion plate 6 via the pull rod 5. A limit mechanism is provided on the side wall of the pull rod 5. A slot 8 is formed in the inner wall of the detector 1, located within the sliding groove of the movable block 3. Figure 2 As can be seen, a wire take-up mechanism is fixedly connected to the outer wall of detector 1.

[0021] The limiting mechanism includes a insertion plate 6. The outer wall of the insertion plate 6 has protrusions, allowing it to be inserted into the slot 8. The insertion plate 6 is fixedly connected to the side wall of the pull rod 5. The right side wall of the insertion plate 6 is elastically connected to the moving block 3 via a return spring 7. The positional relationships described in this document are based on… Figure 1 Mainly.

[0022] Reference Figures 2-4The wire take-up mechanism includes a take-up housing 9, which mainly supports and connects the entire rotating frame 11. The take-up housing 9 is fixedly connected to the outer wall of the detector 1. The rotating frame 11 is rotatably connected to the inner wall of the take-up housing 9. There is a rectangular block inside the take-up housing 9, and a round rod is connected to and passes through the rotating frame 11, allowing the rotating frame 11 to rotate along the outer wall of the round rod. A spring piece 12 is fixedly connected to the top of the rotating frame 11. The spring piece 12 is made of plastic and can fix the wire harness by utilizing the elastic deformation of the plastic. A baffle 10 is slidably connected to the outer wall of the take-up housing 9. The baffle 10 is fixed to the take-up housing by its own friction. The outer wall of the baffle 10 slides to prevent dust and impurities from entering the storage shell 9. The outer wall of the baffle 10 is fixedly connected with a friction pad 13, which can increase friction and help the staff push the baffle 10 to move. Multiple sets of springs 12 are provided, and multiple sets of springs 12 are evenly distributed on the top of the rotating frame 11. The upper end of the spring 12 is an outwardly opening arc surface, which can make the wire harness squeeze the upper end of the spring 12, so that the two springs 12 are separated and the wire harness can enter the two springs 12. Multiple sets of friction pads 13 are provided, and multiple sets of friction pads 13 are evenly distributed on the outer wall of the baffle 10.

[0023] Reference Figures 1-3 The right side wall of the insert plate 6 is fixedly connected to one end of the reset spring 7. When the insert plate 6 moves to the right, it will compress the reset spring 7. When resetting, the spring force of the reset spring 7 will carry the insert plate 6 to reset. The other end of the reset spring 7 is fixedly connected to the right inner wall of the moving block 3. The insert plate 6 is slidably connected to the inner wall of the moving block 3. The insert plate 6 is inserted into the inner wall of the slot 8. The size of the protrusion of the slot 8 matches that of the insert plate 6, which can satisfy the insertion of the insert plate 6 into the slot 8. The finger sleeve 4 is circular in shape. Multiple sets of finger sleeves 4 are provided. Multiple sets of finger sleeves 4 are evenly distributed on the outer wall of the moving block 3. The detector 1 and the detection head 2 are connected by a wire harness.

[0024] Working principle: First, when using the device, the operator's fingers can pass through the finger sleeve 4. Since the finger sleeve 4 is elastic, it can wrap around the fingers and generate friction to prevent the detector 1 from falling off the hand during use. If the position of the finger sleeve 4 is adjusted according to the user's finger placement habits, the lever 5 can be pulled. The lever 5 drives the insert plate 6 to move laterally, so that the protrusion of the insert plate 6 is pulled out of the slot 8. At this time, the moving block 3 can slide up and down along the outer wall of the detector 1. After adjusting to the appropriate position, the lever 5 is released, and the elastic force of the return spring 7 pushes the insert plate 6 to reset. The protrusion of the insert plate 6 is reinserted into the corresponding slot 8 to complete the adjustment.

[0025] After the device is used, the detector 1 and the detection head 2 can be pulled out from the wire harness connection end. Push the baffle 10 to slide along the outer wall of the storage shell 9 to open the opening of the storage shell 9. Then rotate the entire rotating frame 11 so that the rotating frame 11 rotates out of the storage shell 9 to facilitate subsequent winding. Finally, the wire harness is wound on the rotating frame 11, and the wire harness squeezes the spring 12 to produce elastic deformation. The spring 12 uses its own elasticity to clamp and fix the wire harness. After winding is completed, rotate the entire rotating frame 11 back to its original position. Finally, push the baffle 10 back to its original position so that the baffle 10 stably blocks the opening of the storage shell to prevent dust and impurities from entering. When it is necessary to release the wire, the reverse operation can be performed to take out the wire harness.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
