[0020] See also Figures 1 to 4 The present invention provides a construction intelligent wiring system detection device 100, which is used to detect wiring systems such as cables during construction. The construction intelligent wiring system detection device 100 includes a housing 10, a detection head 11, a transmission mechanism 12, a first spring 13, a push rod 14 and a limit mechanism 15.

[0021] The shell 10 is the main structure of the intelligent wiring system detection device 100 for building construction, and it is roughly in the shape of a rectangular parallelepiped to facilitate user holding. The shell 10 is provided with a accommodating cavity 106, which is a cavity located inside the shell 10, and the accommodating cavity 106 is used to accommodate other structures and components arranged inside the shell 10. The shell 10 includes a connected top wall 101 and a first side wall 102, and the first side wall 102 is provided with a make way opening 1021 extending in the vertical direction. The top wall 101 and the first side wall 102 are both part of the structure of the shell 10. When the intelligent wiring system detection device 100 for building construction is placed in the vertical direction, the top wall 101 is located at the top of the shell 10 and is arranged roughly in the horizontal direction, and the first side wall 102 is located on one side of the shell 10 and is arranged roughly in the vertical direction.

[0022] The detection head 11 is a detection component of the building construction intelligent wiring system detection device 100, and the appearance of the detection head 11 is roughly cylindrical. The detection head 11 is movably arranged on the top wall 101 along the vertical direction.

[0023] The transmission mechanism 12 is transmission-connected to the bottom end of the detection head 11 and is located in the accommodating cavity 106. A limit end 121 is provided at the bottom of the transmission mechanism 12. The limit end 121 is used to abut against the limit mechanism 15 to limit the transmission mechanism 12 and the detection head 11 in the vertical direction.

[0024] The first spring 13 is disposed in the accommodating cavity 106, with one end of the first spring 13 abutting against the top wall 101, and the other end abutting against the transmission mechanism 12. It should be noted that the above "abutting" means abutting and connecting, indicating that the first spring 13 is in a compressed state in the above state.

[0025] One end of the push rod 14 is connected to the transmission mechanism 12, and the other end passes through the clearance opening 1021 and extends to the outside of the housing 10. The user can move the push rod 14 to drive the transmission mechanism 12 and the detection head 11 to move.

[0026] The limiting mechanism 15 is disposed in the accommodating cavity 106, and the limiting mechanism 15 abuts against the limiting end 121 of the transmission mechanism 12 so that the first spring 13 is compressed and at least part of the structure of the detection head 11 is located outside the housing 10. The limiting mechanism 15 is used to separate from the limiting end 121 when the construction intelligent wiring system detection device 100 vibrates due to falling, so that the first spring 13 pushes the transmission mechanism 12 vertically downward to drive the detection head 11 to move into the accommodating cavity 106. It should be noted that the above-mentioned "the limiting mechanism 15 is separated from the limiting end 121" means that the limiting mechanism 15 and the limiting end 121 do not contact each other, that is, the limiting mechanism 15 cannot provide a limiting effect on the limiting end 121 (or the transmission mechanism 12) in the vertical direction.

[0027] When the above-mentioned intelligent wiring system detection device 100 for building construction is in normal use, the limiting mechanism 15 abuts against the limiting end 121 of the transmission mechanism 12 so that the first spring 13 is compressed and at least part of the structure of the detection head 11 is located outside the housing 10. When the intelligent wiring system detection device 100 for building construction accidentally falls, the vibration caused by the fall will cause the limiting mechanism 15 to separate from the limiting end 121. At this time, the limiting mechanism 15 loses the abutting force on the limiting end 121, and the first spring 13 will push the transmission mechanism 12 and the detection head 11 to move vertically downward, and finally the detection head 11 is completely moved into the accommodating cavity 106 to protect the detection head 11. In summary, the above-mentioned intelligent wiring system detection device 100 for building construction can automatically retract the detection head 11 into the interior of the housing 10 when accidentally falling, thereby reducing the damage to the detection head 11 caused by the accidental fall, and has the beneficial effects of good protection effect on the detection head 11 and long service life.

[0028] See also Figures 3 to 8 In some embodiments, the transmission mechanism 12 includes a pushing cylinder 122, a first mounting plate 123, a gear 124, a supporting cylinder 125, a second mounting plate 126, a first rack 127, a second rack 128, a second spring 129, a top connection member 130 and a supporting ball 131.

[0029] The abutting cylinder 125 includes a connected abutting portion 1251 and a mounting portion 1252. The abutting portion 1251 is a truncated cone-shaped hollow structure, and has a first opening 1253 located at its bottom end and a second opening 1254 located at its top end, and the diameter of the first opening 1253 is smaller than the diameter of the second opening 1254. The bottom end of the abutting portion 1251 is the limiting end 121 and is abutted against the limiting mechanism 15. The mounting portion 1252 is an annular structure, and the mounting portion 1252 is arranged at the top end of the abutting portion 1251, and the mounting portion 1252 surrounds the outer periphery of the second opening 1254. The pushing cylinder 122 is a cylindrical structure that is roughly cylindrical, and the pushing cylinder 122 can be movably sleeved on the outer periphery of the mounting portion 1252. The first mounting plate 123 is a long strip plate-shaped structure, and the first mounting plate 123 is arranged on the inner side wall of the pushing cylinder 122 and is parallel to the axial direction of the pushing cylinder 122. The gear 124 is rotatably connected to the first mounting plate 123. A clearance hole 1255 is provided on the abutting cylinder 125, and the first mounting plate 123 is penetrated in the clearance hole 1255. The second mounting plate 126 is a long strip plate-like structure, and the second mounting plate 126 is vertically arranged on the end face of the mounting portion 1252 away from the abutting portion 1251, and the second mounting plate 126 is in contact with the inner wall of the pushing cylinder 122. The first rack 127 is arranged on the side of the second mounting plate 126 away from the pushing cylinder 122 in the vertical direction, and meshes with the gear 124, and the second rack 128 is arranged on the bottom end of the outer wall of the detection head 11 in the vertical direction, and meshes with the gear 124. One end of the pushing rod 14 is connected to the outer wall of the pushing cylinder 122, and the outer wall of the pushing cylinder 122 is provided with a sliding plate 1221, and the sliding plate 1221 is a long strip plate-like structure, and one end of the first spring 13 is in contact with the sliding plate 1221. One end of the second spring 129 is connected to the bottom surface of the detection head 11, and the other end is connected to the top surface of the top connecting member 130. The top connecting member 130 is fixedly connected to the inner wall of the push cylinder 122, and the abutting ball 131 is connected to the bottom end of the top connecting member 130 and accommodated in the first opening 1253, and the abutting ball 131 abuts against the limiting mechanism 15.

[0030] Through the above arrangement, when the construction intelligent wiring system detection device 100 is in normal use, the limiting mechanism 15 abuts against the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting tube 125 so that the first spring 13 is compressed and at least part of the structure of the detection head 11 is located outside the housing 10. When the construction intelligent wiring system detection device 100 is accidentally dropped, two situations may occur: the housing 10 contacts and collides with the collision surface (e.g., the ground, a table, etc.); the detection head 11 contacts and collides with the collision surface (e.g., the ground, a table, etc.). When the shell 10 contacts and collides with the collision surface, the vibration of the shell 10 caused by the collision will cause the limiting mechanism 15 to be misaligned and separated from the bottom end of the supporting portion 1251 of the supporting tube 125. At this time, the limiting mechanism 15 loses its supporting force on the supporting portion 1251 of the supporting tube 125. Therefore, under the action of the first spring 13, the first spring 13 will push the sliding plate 1221 and the pushing tube 122 to move vertically downward. In the process of the pushing tube 122 moving vertically downward, the gear 124, the first rack 127 and the second rack 128 remain relatively still, and the detection head 11, the pushing tube 122 and the supporting tube 125 remain relatively still and the three move downward synchronously until the detection head 11 is finally completely moved into the accommodating cavity 106 to protect the detection head 11.When the detection head 11 contacts and collides with the collision surface, the detection head 11 will first move a certain distance into the shell 10 due to the collision force. During the above process, the detection head 11 squeezes the top connecting piece 130 and the supporting ball 131 in the direction away from the top wall 101 through the second spring 129. Since the top connecting piece 130 is connected to the pushing cylinder 122, the pushing cylinder 122 will follow the top connecting piece 130 to move in the direction away from the top wall 101. Since the detection head 11 moves toward the inside of the shell 10, the second rack 128 will move relative to the gear 124 in the direction away from the top wall 101, so that the first rack 127 drives the second mounting plate 126 and the supporting cylinder 125 to move in the direction close to the top wall 101, which will cause the bottom end of the supporting portion 1251 of the supporting cylinder 125 (i.e., the limiting end 121) to separate from the limiting mechanism 15. At this time, the bottom end of the top connecting piece 130 will drive the supporting ball 131 The supporting ball 131 passes through the first opening 1253 and extends to the outside of the supporting cylinder 125, and the supporting ball 131 will be in abutment with the limiting mechanism 15. Since the stability of the supporting ball 131 and the limiting mechanism 15 is poor, the supporting ball 131 will be misaligned with the limiting mechanism 15 so that the limiting mechanism 15 loses its supporting effect on the supporting ball 131, the top connecting member 130, the pushing cylinder 122, the second spring 129 and the detection head 11. At this time, the first spring 13 will push the sliding plate 1221 and the pushing cylinder 122 to move vertically downward. In the process of the vertical downward movement of the pushing cylinder 122, the first rack 127, the gear 124, and the second rack 128 will eventually reach a balanced state and remain relatively still, so that the pushing cylinder 122, the supporting cylinder 125 and the detection head 11 remain relatively still and move vertically downward synchronously until the detection head 11 is finally completely moved into the accommodating cavity 106 to protect the detection head 11.

[0031] See also Figure 3 and Figure 6 In some embodiments, the limiting mechanism 15 includes a limiting ball 151 and a plurality of connecting springs 152. The limiting ball 151 is a spherical structure. One end of the connecting spring 152 is connected to the limiting ball 151, and the other end is connected to the inner wall of the housing 10. The plurality of connecting springs 152 jointly support the limiting ball 151. The limiting ball 151 is used to abut against the limiting end 121, and the diameter of the limiting ball 151 is greater than the diameter of the abutting ball 131.

[0032] Through the above arrangement, when the construction intelligent wiring system detection device 100 is in normal use, the limiting ball 151 abuts against the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting tube 125 so that the first spring 13 is compressed and at least part of the structure of the detection head 11 is located outside the shell 10. When the construction intelligent wiring system detection device 100 accidentally falls and the shell 10 collides with the collision surface, the vibration of the shell 10 caused by the collision will cause the connecting spring 152 to shake, thereby moving the position of the supporting ball 131, causing the supporting ball 131 to be misaligned and separated from the bottom end of the supporting portion 1251 of the supporting cylinder 125. At this time, the supporting ball 131 loses its supporting force on the supporting portion 1251 of the supporting cylinder 125. Therefore, under the action of the first spring 13, the first spring 13 will push the sliding plate 1221, the pushing cylinder 122, the supporting cylinder 125 and the detection head 11 to move downward synchronously until the detection head 11 is finally completely moved into the accommodating cavity 106 to protect the detection head 11. When the construction intelligent wiring system detection device 100 accidentally falls and the detection head 11 contacts and collides with the collision surface, the detection head 11 will first move a distance into the shell 10 due to the collision force. In the above process, the detection head 11 squeezes the top connecting piece 130 and the supporting ball 131 through the second spring 129 to move in the direction away from the top wall 101. Since the top connecting piece 130 is connected to the pushing cylinder 122, the pushing cylinder 122 will follow the top connecting piece 130 to move in the direction away from the top wall 101. Since the detection head 11 moves toward the inside of the shell 10, the second rack 128 will move relative to the gear 124 in the direction away from the top wall 101, so that the first rack 127 drives the second mounting plate 126 and the supporting cylinder 125 to move in the direction close to the top wall 101, which will cause the bottom end of the supporting portion 1251 of the supporting cylinder 125 (i.e., the limit end 1 21) is separated from the limiting ball 151. At this time, the bottom end of the top connecting member 130 will drive the supporting ball 131 to pass through the first opening 1253 and extend to the outside of the supporting cylinder 125. The supporting ball 131 will abut against the limiting ball 151. Since the supporting ball 131 and the limiting ball 151 are in point contact, the stability of the abutment between the supporting ball 131 and the limiting ball 151 is poor. Therefore, the supporting ball 131 will be misaligned with the limiting ball 151 so that the limiting ball 151 loses its supporting effect on the supporting ball 131, the top connecting member 130, the pushing cylinder 122, the second spring 129 and the detection head 11. At this time, under the action of the first spring 13, the first spring 13 will push the sliding plate 1221, the pushing cylinder 122, the supporting cylinder 125 and the detection head 11 to move vertically downward until the detection head 11 is finally completely moved into the accommodating cavity 106 to protect the detection head 11.

[0033] In addition, after the use of the intelligent wiring system detection device 100 for building construction is completed, the operator can also pull the push rod 14 in the direction away from the top wall 101. The above-mentioned external force will cause the bottom end of the supporting portion 1251 of the supporting tube 125 (i.e., the limiting end 121) to be misaligned and separated from the limiting ball 151. At this time, the limiting ball 151 will move and abut against the outer wall of the supporting portion 1251, so that the limiting ball 151 loses the vertical limitation on the transmission mechanism 12 and the detection head 11. Therefore, under the action of the first spring 13, the transmission mechanism 12 will move in the direction away from the top wall 101 and drive the detection head 11 to move toward the inside of the shell 10, so that the detection head 11 can be completely retracted into the shell 10, thereby protecting the detection head 11. When the construction intelligent wiring system detection device 100 is needed next time, the operator pulls the push rod 14 toward the top wall 101, so that the transmission mechanism 12 moves toward the top wall 101 and the detection head 11 passes through the top wall 101 and moves toward the outside of the shell. As the supporting tube 125 continues to move toward the top wall 101, when the outer wall of the supporting portion 1251 of the supporting tube 125 separates from the limiting ball 151, the limiting ball 151 returns to its initial position under the combined force of multiple connecting springs 152, so that the limiting ball 151 is re-supported against the bottom end (i.e., the limiting end 121) of the supporting portion 1251 of the supporting tube 125. Under the supporting force of the limiting ball 151, the detection head 11 can be stably exposed from the shell 10 for detection, and the operation is convenient. It should be noted that when the limiting ball 151 abuts against the outer wall of the abutting portion 1251, the abutting ball 131 is accommodated inside the abutting portion 1251, so the abutting ball 131 and the top connecting member 130 will not hinder the limiting ball 151 from moving along the outer wall of the abutting portion 1251 to the bottom end of the abutting portion 1251.

[0034] See also Figure 1 and Figure 4 In some embodiments, the inner side wall of the clearance opening 1021 in the vertical direction is in contact with the push rod 14.

One end of the third connection spring 1523 is connected to the limiting ball 151, and the other end is connected to the surface of the third side wall 104 facing the accommodating cavity 106. One end of the fourth connection spring 1524 is connected to the limiting ball 151, and the other end is connected to the surface of the third side wall 104 facing the accommodating cavity 106. Through the above arrangement, the first connection spring 1521 and the second connection spring 1522 connect the limiting ball 151 to the second side wall 103, the third connection spring 1523 and the fourth connection spring 1524 connect the limiting ball 151 to the third side wall 104, and the second side wall 103 and the third side wall 104 are relatively spaced apart, so the first connection spring 1521, the second connection spring 1522, the third connection spring 1523 and the fourth connection spring 1524 can be connected and supported by the limiting ball 151 together, thereby improving the stability of the limiting ball 151.

[0036] See also Figure 4 and Figure 6 In some embodiments, the top connection member 130 includes a connecting strip 1301 and a top connection rod 1302. The connecting strip 1301 is in the shape of a long strip and is arranged along the radial direction of the pushing cylinder 122. Both ends of the connecting strip 1301 are fixedly connected to the inner side wall of the pushing cylinder 122. The bottom end of the second spring 129 is fixedly connected to the top surface of the connecting strip 1301. The top connection rod 1302 is in the shape of a round rod. The top connection rod 1302 is arranged in the vertical direction. The top end of the top connection rod 1302 is connected to the bottom surface of the connecting strip 1301, and the supporting ball 131 is fixedly connected to the bottom end of the top connection rod 1302. Through the above arrangement, the connecting strip 1301 realizes the stable connection between the top connection member 130 and the pushing cylinder 122, and the top connection rod 1302 realizes the installation of the supporting ball 131. The above arrangement can simplify the morphological structure of the top connection member 130, thereby saving material cost and production cost.

[0037] See also Figure 6In some embodiments, two sliding plates 1221 are provided, and the two sliding plates 1221 are arranged at intervals. The inner side wall of the housing 10 is provided with two slide grooves 105 adapted to the two sliding plates 1221, and the slide grooves 105 are arranged in the vertical direction. The two sliding plates 1221 are respectively embedded in the two slide grooves 105, and the sliding plates 1221 slide in the slide grooves 105. As a specific example, in this embodiment, the two sliding plates 1221 are arranged in a colinear manner, and the two slide grooves 105 are respectively arranged on the surface of the second side wall 103 facing the accommodating cavity 106 and the surface of the third side wall 104 facing the accommodating cavity 106. Through the above arrangement, in the process of moving the push cylinder 122, the sliding plate 1221 will move along the extension direction of the slide groove 105, so the slide groove 105 can guide the sliding plate 1221 and the push cylinder 122 in the vertical direction, so that the movement of the transmission mechanism 12 and the detection head 11 is more stable. Furthermore, the slide groove 105 cooperates with the sliding plate 1221 to limit the rotation of the push cylinder 122, thereby further improving the stability of the transmission mechanism 12 and the detection head 11 during the movement.

[0038] See also Figure 3 and Figure 4 In some embodiments, the first spring 13 is sleeved on the outer periphery of the push cylinder 122 and the detection head 11, and the first spring 13 abuts against at least one of the two sliding plates 1221. Through the above arrangement, the detection head 11 and the push cylinder 122 are located inside the first spring 13, which not only saves the space occupied by the installation of the first spring 13, but also improves the stability of the elastic force of the first spring 13 acting on the sliding plate 1221, which is conducive to the stable movement of the transmission mechanism 12 in the vertical direction under the action of the first spring 13.

[0039] See also Figure 8In some embodiments, two gears 124 are provided, and four first mounting plates 123 are provided, wherein two first mounting plates 123 are arranged at intervals relative to each other, and the other two first mounting plates 123 are arranged at intervals relative to each other, and two gears 124 are respectively provided between two groups of two first mounting plates 123 arranged opposite to each other, and the gears 124 are rotatably connected to the two first mounting plates 123 arranged opposite to each other. Four clearance holes 1255 are provided corresponding to the four first mounting plates 123. Two second mounting plates 126, second racks 128, and first racks 127 are provided corresponding to the two gears 124. Specifically, the four first mounting plates 123 are respectively inserted into the four clearance holes 1255; a single second mounting plate 126 is located between two first mounting plates 123 arranged opposite to each other; a first rack 127 meshing with the gear 124 is provided on the side of each second mounting plate 126 facing the gear 124; and two second racks 128 are both provided at the bottom of the outer wall of the detection head 11, and meshing with the two gears 124 respectively. Through the above arrangement, when the supporting cylinder 125 and the pushing cylinder 122 move relative to each other, the transmission cooperation between the first rack 127, the second rack 128 and the gear 124 is more stable, thereby making the relative movement of the supporting cylinder 125 and the pushing cylinder 122 more stable, thereby improving the stability of the detection head 11 during movement.

[0040] See also Figure 1 The edge of the top surface of the detection head 11 is provided with a chamfer, which can facilitate the detection head 11 to pass through the top wall 101, thereby facilitating the detection head 11 to be moved out of the housing 10 for detection.
