Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In the present application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0045] Referring to Figures 1 to 4 The application provides a detection device, the detection device comprises a detection mechanism 10, a positioning mechanism 20 and a telescopic mechanism 30. The detection mechanism 10 has a first end 11 and a second end 12 arranged oppositely, and the first end 11 is used for being inserted into a slot hole formed in a wall. The positioning mechanism 20 has an adjusting state and a positioning state arranged oppositely. When the positioning mechanism 20 is in the adjusting state, the positioning mechanism 20 is slidably arranged on the detection mechanism 10 to change the distance between the positioning mechanism 20 and the first end 11. When the positioning mechanism 20 is in the positioning state, the positioning mechanism 20 is fixed on the detection mechanism 10 to fix the distance between the positioning mechanism 20 and the first end 11, and the positioning mechanism 20 is used for abutting against the wall. The telescopic mechanism 30 is arranged on the detection mechanism 10, and the telescopic mechanism 30 comprises a telescopic end. The telescopic end is located at the first end 11, and the telescopic end can move relative to the first end 11 to protrude from the first end 11. The telescopic mechanism 30 cooperates with the detection mechanism 10 to detect the depth of the slot hole.

[0046] By using the technical scheme of the application, the positioning mechanism 20 is slidably arranged on the detection mechanism 10. The limit depth of the slot hole can be marked in advance by changing the interval between the positioning mechanism 20 and the first end 11. After the detection mechanism 10 is inserted into the slot hole, when the positioning mechanism 20 abuts against the wall, it indicates that the depth of the slot hole is not less than the limit depth value. At this time, the position of the telescopic end is changed. If the telescopic end can move and protrude from the first end 11, it indicates that the depth of the slot hole is too large and does not meet the requirement of continuous construction. By using the above structure, the detection process of the depth of the slot hole is significantly simplified. The staff does not need to read the value and manually compare again. The staff only needs to cooperate with the telescopic mechanism 30 and the detection mechanism 10 to visually judge whether the depth meets the requirement. By such an arrangement, the efficiency of the depth detection can be improved, the labor intensity of the staff can be reduced, the construction progress can be accelerated, and the visual error in the process of manual reading can be avoided, so that the accuracy and reliability of the detection result are significantly improved.

[0047] In some embodiments, the detection mechanism 10 is provided with a scale line 17, and the value of the first end 11 is smaller, and the value of the second end 12 is larger.

[0048] Referring to Figure 5The detection device further comprises an alarm mechanism 40 arranged on the positioning mechanism 20, the alarm mechanism 40 is used for detecting the distance between the positioning mechanism 20 and the wall body, and the alarm mechanism 40 alarms when the positioning mechanism 20 abuts against the wall body. In this way, when the positioning mechanism 20 abuts against the wall body, the alarm mechanism 40 can timely remind the staff to perform subsequent operations, further improve the detection efficiency, and at the same time, the staff does not need to observe the position of the positioning mechanism 20 relative to the wall body at all times, thereby reducing the labor intensity of the staff.

[0049] Referring to Figure 1 , Figure 4 and Figure 5 , the detection mechanism 10 has a first side 13 and a second side 14 arranged opposite to each other. The positioning mechanism 20 comprises a positioning assembly 21 and a connecting assembly 22. The positioning assembly 21 is slidably sleeved on the outer side of the detection mechanism 10, the alarm mechanism 40 is arranged on the side of the positioning assembly 21 close to the second side 14, and the positioning assembly 21 has an adjusting state and a positioning state arranged opposite to each other. The connecting assembly 22 is arranged on the side of the positioning assembly 21 close to the first side 13, and the connecting assembly 22 is used for fixing the positioning assembly 21 on the detection mechanism 10. In this way, the alarm mechanism 40 is arranged on the positioning assembly 21, and the positioning assembly 21 can synchronously drive the alarm mechanism 40 to move in the moving process, so that the alarm mechanism 40 can detect the position of the positioning assembly 21, the accuracy of the detection position of the alarm mechanism 40 is ensured, and the reliability of the detection device is further improved.

[0050] In some embodiments, the positioning assembly 21 is a shell structure.

[0051] Specifically, the side of the positioning assembly 21 close to the first side 13 is provided with a first connecting hole 211, the connecting assembly 22 is slidably arranged in the first connecting hole 211, the connecting assembly 22 has a connecting position and a avoiding position arranged opposite to each other, and the connecting assembly 22 and the detection mechanism 10 have a connecting structure. When the connecting assembly 22 is located at the connecting position, the connecting structure is used for fixing the positioning assembly 21 on the detection mechanism 10, and when the connecting assembly 22 is located at the avoiding position, the positioning assembly 21 can slide relative to the detection mechanism 10. In this way, the staff only needs to change the position of the connecting assembly 22 to fix and slide the positioning assembly 21, the staff can change the value of the limit depth, the structure is simple, and the operation is convenient.

[0052] Referring to Figure 1 and Figure 2 , the X direction is the first direction.

[0053] Referring to Figure 4The first side 13 is provided with a plurality of connecting grooves 15 in the first direction, and the connecting assembly 22 comprises a first connecting unit 221 and a first reset unit 222. The first connecting unit 221 has oppositely arranged connecting and avoiding positions, and comprises a connecting piece 2211. When the first connecting unit 221 is located at the connecting position, the connecting piece 2211 is located in the connecting groove 15. When the first connecting unit 221 is located at the avoiding position, the connecting piece 2211 is away from the connecting groove 15, and the connecting piece 2211 and the connecting groove 15 form a connecting structure in cooperation. The first reset unit 222 is arranged between the connecting groove 15 and the connecting piece 2211, and is used for driving the first connecting unit 221 to move from the avoiding position to the connecting position. In this way, the first connecting unit 221 can be switched between the connecting position and the avoiding position when the position of the first connecting unit 221 is changed. Moreover, the arrangement of the first reset unit 222 ensures that the first connecting unit 221 can automatically and quickly return and be fixed in the connecting groove 15 after being pulled out of the connecting groove 15. This greatly improves the convenience and efficiency of operation, avoiding the tediousness of manual pushing back or adjustment. Moreover, the positioning of the first connecting unit 221 in the connecting groove 15 provides a stable locking state, enhancing the reliability of the detection device. At the same time, the first connecting unit 221 can be effectively prevented from moving accidentally in a non-operating state, ensuring the stability of the positioning mechanism 20.

[0054] In some embodiments, the cross-sectional area of the connecting groove 15 gradually decreases in the direction close to the second side 14, and the cross-sectional area of the connecting piece 2211 gradually decreases in the direction close to the second side 14. In this way, the smoothness of the movement of the connecting piece 2211 into the connecting groove 15 can be improved, avoiding jamming.

[0055] In some embodiments, the first connecting unit 221 further comprises a first connecting rod 2212 and an operating piece 2213. The operating piece 2213 is arranged at one end of the first connecting rod 2212, and the connecting piece 2211 is located at the other end of the first connecting rod 2212. When the first connecting unit 221 is in the connecting position, the operating piece 2213 protrudes from the positioning assembly 21, so that the worker can move the first connecting unit 221 to the avoiding position through the operating piece 2213.

[0056] In some embodiments, the operating piece 2213 is a pull ring, so that the worker can pull it out conveniently.

[0057] In some embodiments, a first limiting piece 213 is arranged in the first connecting hole 211. The first limiting piece 213 has a first through hole, and the first connecting rod 2212 passes through the first through hole. One end of the first reset unit 222 abuts against the first limiting piece 213, and the other end of the first reset unit 222 abuts against the connecting piece 2211.

[0058] Referring to Figure 5 The positioning component 21 is provided with a second connecting hole 212 on the side close to the second side 14, and the axis of the second connecting hole 212 is parallel to the first direction. The alarm mechanism 40 comprises an alarm component 41 and a detection component 42. The alarm component 41 has a detection end 4111 located in the second connecting hole 212. The detection component 42 is movably arranged in the second connecting hole 212 along the axis of the second connecting hole 212, and protrudes out of the second connecting hole 212 on the side close to the first end 11. The detection component 42 has an inductive position and an initial position arranged oppositely. When the detection component 42 is located in the inductive position, one end of the detection component 42 is used to abut against the wall, and the other end of the detection component 42 abuts against and is communicatively connected with the detection end 4111. When the detection component 42 is located in the initial position, the detection component 42 is away from the detection end 4111. After the detection mechanism 10 is inserted into the slot hole, if the depth of the slot hole is greater than the limit depth value, the detection component 42 will contact the wall and slide towards the direction where the detection end 4111 is located. When the detection component 42 abuts against the detection end 4111, the alarm component 41 works. At this time, the detection mechanism 10 cannot continue to be inserted because the positioning component 21 abuts against the wall, and it also indicates that the depth of the slot hole has reached the limit depth value. In this way, the alarm mechanism 40 can timely feedback the depth of the slot hole. Once the limit depth is reached, the alarm is immediately started, and the worker can quickly know it, so as to carry out subsequent operation. At the same time, the alarm mechanism 40 can be linked with the positioning mechanism 20. The alarm mechanism 40 and the positioning mechanism 20 cooperate to detect the depth of the slot hole, and further reduce the complexity of detecting the depth.

[0059] Referring to Figure 5The detection assembly 42 comprises a second connecting unit 421 and a second reset unit 422. The second connecting unit 421 has an inductive position and an initial position arranged oppositely. The second connecting unit 421 comprises an abutting piece 4211. When the second connecting unit 421 is located at the inductive position, the abutting piece 4211 abuts against and is in communication connection with the detection end 4111. When the second connecting unit 421 is located at the initial position, the abutting piece 4211 is away from the detection end 4111. The second reset unit 422 is arranged between the second connecting unit 421 and the inner wall of the second connecting hole 212. The second reset unit 422 is used for driving the second connecting unit 421 to move from the initial position to the inductive position. With the above structure, when the second connecting unit 421 abuts against the wall, the detection device is continuously inserted into the slot hole, and the second connecting unit 421 can move from the initial position to the inductive position. In this way, only when the detection assembly 42 abuts against the wall, the alarm assembly 41 can work, and the detection assembly 42 can ensure the reliability of the alarm assembly 41. At the same time, the second reset unit 422 can avoid the alarm assembly 41 from working due to the accidental touch of the detection assembly 42. Moreover, the arrangement of the second reset unit 422 ensures that the second connecting unit 421 can automatically and quickly move to the initial position after moving to the inductive position, avoiding the alarm assembly 41 from alarming for a long time. This greatly improves the convenience and efficiency of operation, avoiding the tediousness of manual pushing back or adjustment.

[0060] In some embodiments, the second connecting unit 421 further comprises a second connecting rod 4212 and a contact piece 4213. The contact piece 4213 is arranged at one end of the second connecting rod 4212, and the abutting piece 4211 is located at the other end of the second connecting rod 4212. When the second connecting unit 421 is at the initial position, the contact piece 4213 protrudes from the positioning assembly 21, so as to facilitate the contact between the contact piece 4213 and the wall.

[0061] In some embodiments, the second connecting hole 212 is provided with a second limiting piece 215. The second limiting piece 215 has a second through hole, and the second connecting rod 4212 is arranged in the second through hole. One end of the second reset unit 422 abuts against the second limiting piece 215, and the other end of the first reset unit 222 abuts against the contact piece 4213.

[0062] Specifically, the alarm assembly 41 comprises a sensor 411 and an alarm piece 412. One end of the sensor 411 is a detection end 4111. The alarm piece 412 is arranged on the positioning assembly 21, and the other end of the sensor 411 is in communication connection with the alarm piece 412. In this way, the alarm assembly 41 has a simple structure, and at the same time, the alarm assembly 41 is sensitive in response, further facilitating the subsequent operation of the staff.

[0063] In some embodiments, the positioning assembly 21 is provided with a communication hole 214 near one side of the second side 14, the communication hole 214 is in communication with the second connecting hole 212, the alarm member 412 is arranged in the communication hole 214, and the alarm member 412 protrudes from the positioning assembly 21, one end of the sensor 411 is arranged in the second connecting hole 212, and the other end of the sensor 411 is connected with the alarm member 412.

[0064] In some embodiments, the sensor 411 is a contact sensor.

[0065] Referring to Figure 3 The telescopic mechanism 30 comprises a third connecting unit 31 and a third reset unit 32. The third connecting unit 31 is slidably arranged on the detection mechanism 10, the third connecting unit 31 extends along the first direction, and the third connecting unit 31 comprises a telescopic end. The third reset unit 32 is arranged between the third connecting unit 31 and the second end 12, and the third reset unit 32 is used for driving the third connecting unit 31 to move towards the second end 12. In this way, when the alarm member 412 alarms, the worker pushes the third connecting unit 31 to move towards the first end 11, and when the third connecting unit 31 can continue to push for a small distance, it indicates that the depth of the slot hole is greater than the limit depth value. In this way, it is convenient for the worker to operate, and at the same time, the structure is simple, and it is convenient for the worker to process the telescopic mechanism 30. Moreover, the arrangement of the third reset unit 32 ensures that the worker can automatically and quickly move to the original position after pushing the third connecting unit 31, avoiding the tediousness of manual pushing back or adjustment.

[0066] Referring to Figure 3 The detection mechanism 10 has a third connecting hole 16 extending along the first direction, and the third connecting unit 31 is slidably arranged in the third connecting hole 16. In this way, interference between the telescopic mechanism 30 and other structures can be avoided, and at the same time, the detection mechanism 10 can protect the telescopic mechanism 30 from damage, and the third connecting hole 16 can guide the movement of the third connecting unit 31 to ensure the smoothness of the movement of the third connecting unit 31.

[0067] In some embodiments, the third connecting unit 31 comprises a third connecting rod 311, a first fixing member 312 and a second fixing member 313, the first fixing member 312 is arranged at one end of the third connecting rod 311, the second fixing member 313 is arranged at the other end of the third connecting rod 311, and the first fixing member 312 and the second fixing member 313 are larger than the diameter of the third connecting hole 16. In this way, the third connecting unit 31 can be prevented from falling out of the third connecting hole 16.

[0068] In some embodiments, the third connecting unit 31 and the third connecting hole 16 are provided with a guide structure.

[0069] In the present application, the detection device further comprises a protection mechanism 50 sleeved on the first end 11, which can protect the detection mechanism 10 from being worn by the gravel in the slot.

[0070] In some embodiments, the protection mechanism 50 can be a metal sleeve.

[0071] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.
