[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention provides an embodiment of a bridge crack detector, comprising:

[0024] The test body 1 and the transmission line 4 are provided with a connection port 11 on the top of the test body 1. One end of the transmission line 4 is plugged into the connection port 11 via a plug connector 42, and the other end of the transmission line 4 is connected to a planar transducer 41. By connecting the test body 1 and the planar transducer 41 to each other via the transmission line 4, the test body 1 and the transmission line 4 can be held separately to detect cracks in the bridge and determine the crack depth and width data.

[0025] The handle 2 has a connection base 21 at its top end, which is fixedly connected to the end of the test body 1 away from the connection port 11. A threaded post 24 is threadedly connected to the end of the handle 2 away from the connection base 21, and an anti-slip wheel 23 is provided at one end of the threaded post 24. The anti-slip wheel 23 and the threaded post 24 cooperate with each other to block the open end of the handle 2, thereby improving the stability and safety of parts storage.

[0026] The storage rod 3 has one end fixedly connected to the second abutment platform 31, and the other end of the storage rod 3 is fixedly connected to the guide plate 32. The guide plate 32 is slidably connected to the inside of the handle 2. The storage rod 3 is used for winding and storing the transmission line 4, and the guide plate 32 is mainly used for sliding guidance and limiting.

[0027] Furthermore, the handle 2 has a hollow structure, and the inner wall of the handle 2 is provided with a sponge protective pad. The inner wall of the handle 2 is provided with a limiting slide groove adapted to the guide plate 32. By opening the limiting slide groove, the guide plate 32 is adapted to slide and guide, thereby improving the sliding stability of the guide plate 32. At the same time, the setting of the sponge protective pad on the inner wall of the handle 2 can further provide good protective effect.

[0028] Furthermore, a traction rope 22 is fixedly connected to the outer wall of the handle 2, and the other end of the traction rope 22 is fixedly connected to the outer wall of the anti-slip wheel 23. The outer wall of the anti-slip wheel 23 is provided with anti-slip grooves. The setting of the anti-slip grooves increases the friction with the hand, thereby ensuring the stability of the rotation of the anti-slip wheel 23.

[0029] Furthermore, the diameter of the anti-slip wheel 23 is larger than the diameter of the handle 2, and the end of the threaded column 24 away from the anti-slip wheel 23 is fixedly connected to the first abutment platform 25, and the diameter of the first abutment platform 25 is smaller than the diameter of the threaded column 24. Through the setting of the first abutment platform 25, the second abutment platform 31 can be cooperated with to realize the abutment and accommodation of the plug connector 42, thereby improving the stability of the accommodation of the planar transducer 41.

[0030] Furthermore, a sponge pad is provided on the side where the second abutment platform 31 and the first abutment platform 25 are close to each other, and the second abutment platform 31 and the first abutment platform 25 are used to clamp and position the planar transducer 41. By squeezing and storing the sponge pad, the squeezing and limiting of the planar transducer 41 are completed, ensuring the stability of the storage of the planar transducer 41 and preventing it from shaking and bumping.

[0031] Furthermore, the length of the storage rod 3 is smaller than the length of the handle 2, and the outside of the storage rod 3 is used for winding the transmission line 4. The outer wall of the guide plate 32 is provided with an integrated circular array of limiting protrusions, which mainly play the role of sliding limit. The diameter of the planar transducer 41 is smaller than the inner diameter of the handle 2. The outer wall of the handle 2 is provided with an anti-slip rubber sleeve, which improves the hand-holding comfort while increasing the hand-holding friction.

[0032] Working principle: The test body 1, transmission line 4, planar transducer 41 and plug connector 42 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When using the utility model, first hold the anti-slip wheel 23 and rotate it to open the handle 2, then take out the planar transducer 41, further pull the storage rod 3, pull it out and take out the transmission line 4, and then realize the connection between the test body 1 and the planar transducer 41 through the transmission line 4, and then hold the handle 2 and the planar transducer 41 to realize the detection and processing of bridge cracks.
