[0030] Please refer to Figures 1 to 4 , this invention provides a detection device 100 for an intelligent cabling system in building construction, which is used to detect cabling systems such as cables during the building construction process. The above-mentioned detection device 100 for an intelligent cabling system in building construction includes a housing 10, a detection head 11, a transmission mechanism 12, a first spring 13, a push rod 14, and a limiting mechanism 15.

[0031] The housing 10 is the main structure of the detection device 100 for an intelligent cabling system in building construction, and it is generally in a cuboid shape for the convenience of the user to hold. The housing 10 is provided with a receiving cavity 106, and the receiving cavity 106 is a cavity located inside the housing 10, and the receiving cavity 106 is used to accommodate other structures and components arranged inside the housing 10. The housing 10 includes a connected top wall 101 and a first side wall 102, and a relief opening 1021 extending in the vertical direction is provided on the first side wall 102. Both the top wall 101 and the first side wall 102 are part of the structures that make up the housing 10. When the detection device 100 for an intelligent cabling system in building construction is placed in the vertical direction, the top wall 101 is located at the top of the housing 10 and is generally arranged in the horizontal direction, and the first side wall 102 is located on one side of the housing 10 and is generally arranged in the vertical direction.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] When the above-mentioned detection device 100 for the intelligent wiring system in building construction is in a normal use state, 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 detection device 100 for the intelligent wiring system in building construction accidentally drops, the vibration caused by the drop 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. Finally, the detection head 11 completely moves into the accommodation cavity 106 to achieve the protection of the detection head 11. To sum up, the above-mentioned detection device 100 for the intelligent wiring system in building construction can automatically retract the detection head 11 into the interior of the housing 10 when accidentally dropping, so as to reduce the damage caused by accidental dropping to the detection head 11, and it has beneficial effects such as good protection effect on the detection head 11 and long service life.

[0038] Please refer to Figures 3 to 8 , in some embodiments, the transmission mechanism 12 includes a push cylinder 122, a first mounting plate 123, a gear 124, a abutting cylinder 125, a second mounting plate 126, a first rack 127, a second rack 128, a second spring 129, a top contact member 130 and a abutting ball 131.

[0039] 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.

[0040] With the above settings, in the normal use state of the intelligent wiring system detection device 100 for building construction, the limiting mechanism 15 abuts against the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting cylinder 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 intelligent wiring system detection device 100 for building construction accidentally falls, two situations will occur: the housing 10 contacts and collides with the collision surface (such as the ground, desktop, etc.); the detection head 11 contacts and collides with the collision surface (such as the ground, desktop, etc.). When the situation of the housing 10 contacting and colliding with the collision surface occurs, the vibration generated by the collision of the housing 10 will cause the limiting mechanism 15 to be misaligned and separated from the bottom end of the abutting portion 1251 of the abutting cylinder 125. At this time, the limiting mechanism 15 loses the supporting force on the abutting portion 1251 of the abutting cylinder 125. Therefore, under the action of the first spring 13, the first spring 13 will push the sliding plate 1221 and the pushing cylinder 122 to move vertically downward. During the vertical downward movement of the pushing cylinder 122, the gear 124, the first rack 127, and the second rack 128 remain relatively stationary, and the detection head 11, the pushing cylinder 122, and the abutting cylinder 125 remain relatively stationary and the three move downward synchronously until finally the detection head 11 is completely moved into the accommodation cavity 106 to achieve the protection of 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 housing 10 under the collision force. During the above process, the detection head 11 squeezes the abutting member 130 and the abutting ball 131 through the second spring 129 and moves away from the top wall 101. Since the abutting member 130 is connected to the push cylinder 122, the push cylinder 122 will move away from the top wall 101 following the abutting member 130. Since the detection head 11 moves into the interior of the housing 10, the second rack 128 will move away from the top wall 101 relative to the gear 124, so that the first rack 127 drives the second mounting plate 126 and the abutting cylinder 125 to move towards the top wall 101. This will cause the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting cylinder 125 to separate from the limiting mechanism 15. At this time, the bottom end of the abutting member 130 will drive the abutting ball 131 to pass through the first opening 1253 and extend outside the abutting cylinder 125. The abutting ball 131 will abut against the limiting mechanism 15. However, due to the poor stability of the abutting between the abutting ball 131 and the limiting mechanism 15, the abutting ball 131 will be misaligned with the limiting mechanism 15, causing the limiting mechanism 15 to lose the supporting effect on the abutting ball 131, the abutting member 130, the push 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 push cylinder 122 to move vertically downward. During the vertical downward movement of the push cylinder 122, the first rack 127, the gear 124, and the second rack 128 will finally reach an equilibrium state and remain relatively stationary, so that the push cylinder 122, the abutting cylinder 125, and the detection head 11 remain relatively stationary and move vertically downward synchronously until the detection head 11 is completely moved into the accommodation cavity 106 finally to realize the protection of the detection head 11.

[0041] Please refer to 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 side 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 larger than the diameter of the abutting ball 131.

[0042] With the above settings, when the intelligent wiring system detection device 100 for building construction is in a normal use state, the limiting ball 151 abuts against the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting cylinder 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 intelligent wiring system detection device 100 for building construction accidentally drops and the housing 10 contacts and collides with the collision surface, the vibration generated by the collision of the housing 10 will cause the connecting spring 152 to shake, thereby causing the position of the abutting ball 131 to move, so that the abutting ball 131 is misaligned and separated from the bottom end of the abutting portion 1251 of the abutting cylinder 125. At this time, the abutting ball 131 loses the supporting force on the abutting portion 1251 of the abutting 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 abutting cylinder 125 and the detection head 11 to move downward synchronously until finally the detection head 11 completely moves into the accommodating cavity 106 to realize the protection of the detection head 11. When the intelligent wiring system detection device 100 for building construction accidentally drops and the detection head 11 contacts and collides with the collision surface, the detection head 11 will first move a certain distance into the housing 10 under the collision force. During the above process, the detection head 11 squeezes the top contact member 130 and the abutting ball 131 through the second spring 129 and moves in a direction away from the top wall 101. Since the top contact member 130 is connected to the pushing cylinder 122, the pushing cylinder 122 will move in a direction away from the top wall 101 following the top contact member 130. Since the detection head 11 moves into the interior of the housing 10, the second rack 128 will move in a direction away from the top wall 101 relative to the gear 124, thereby causing the first rack 127 to drive the second mounting plate 126 and the abutting cylinder 125 to move in a direction close to the top wall 101. This will cause the bottom end (i.e., the limiting end 121) of the abutting portion 1251 of the abutting cylinder 125 to separate from the limiting ball 151. At this time, the bottom end of the top contact member 130 will drive the abutting ball 131 to pass through the first opening 1253 and extend outside the abutting cylinder 125. The abutting ball 131 will abut against the limiting ball 151. Since the abutting ball 131 and the limiting ball 151 are in point contact, the stability of the abutting between the abutting ball 131 and the limiting ball 151 is poor. Therefore, the abutting ball 131 will be misaligned with the limiting ball 151 so that the limiting ball 151 loses the supporting effect on the abutting ball 131, the top contact 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 abutting cylinder 125 and the detection head 11 to move vertically downward until finally the detection head 11 completely moves into the accommodating cavity 106 to realize the protection of the detection head 11.

[0043] Please refer to Figure 1 and Figure 4, in some embodiments, the inner sidewall of the relief opening 1021 in the vertical direction is in contact with the push rod 14. Through the above arrangement, when the operator moves the push rod 14, the relief opening 1021 can guide the push rod 14 in the vertical direction, thereby improving the stability of the movement of the push rod 14, the transmission mechanism 12, and the detection head 11.

[0044] Please refer to Figure 1 , Figures 6 to 8 , in some embodiments, the housing 10 further includes a second sidewall 103 and a third sidewall 104 that are relatively spaced apart. The second sidewall 103 is connected to both the top wall 101 and the first sidewall 102, and the third sidewall 104 is connected to both the top wall 101 and the first sidewall 102. The plurality of connecting springs 152 at least includes a first connecting spring 1521, a second connecting spring 1522, a third connecting spring 1523, and a fourth connecting spring 1524. One end of the first connecting spring 1521 is connected to the limiting ball 151, and the other end is connected to the surface of the second sidewall 103 facing the accommodating cavity 106. One end of the second connecting spring 1522 is connected to the limiting ball 151, and the other end is connected to the surface of the second sidewall 103 facing the accommodating cavity 106. One end of the third connecting spring 1523 is connected to the limiting ball 151, and the other end is connected to the surface of the third sidewall 104 facing the accommodating cavity 106. One end of the fourth connecting spring 1524 is connected to the limiting ball 151, and the other end is connected to the surface of the third sidewall 104 facing the accommodating cavity 106. Through the above arrangement, the first connecting spring 1521 and the second connecting spring 1522 connect the limiting ball 151 to the second sidewall 103, and the third connecting spring 1523 and the fourth connecting spring 1524 connect the limiting ball 151 to the third sidewall 104. The second sidewall 103 and the third sidewall 104 are relatively spaced apart. Therefore, the first connecting spring 1521, the second connecting spring 1522, the third connecting spring 1523, and the fourth connecting spring 1524 can jointly connect and support the limiting ball 151, thereby improving the stability of the limiting ball 151.

[0045] Please refer to Figure 4 and Figure 6, in some embodiments, the abutting member 130 includes a connecting bar 1301 and an abutting rod 1302. The connecting bar 1301 is strip-shaped and arranged along the radial direction of the pushing cylinder 122. Both ends of the connecting bar 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 bar 1301. The abutting rod 1302 is rod-shaped and arranged along the vertical direction. The top end of the abutting rod 1302 is connected to the bottom surface of the connecting bar 1301, and the abutting ball 131 is fixedly connected to the bottom end of the abutting rod 1302. Through the above settings, the connecting bar 1301 realizes the stable connection between the abutting member 130 and the pushing cylinder 122, and the abutting rod 1302 realizes the installation of the abutting ball 131. The above settings can simplify the morphological structure of the abutting member 130, thereby saving material costs and production costs.

[0046] Please refer to Figure 6 , in some embodiments, there are two sliding plates 1221, and the two sliding plates 1221 are arranged at intervals. Two sliding grooves 105 adapted to the two sliding plates 1221 are provided on the inner side wall of the housing 10. The sliding grooves 105 are arranged along the vertical direction, and the two sliding plates 1221 are respectively embedded in the two sliding grooves 105, and the sliding plates 1221 slide in the sliding grooves 105. As a specific example, in this embodiment, the two sliding plates 1221 are arranged collinearly, and the two sliding 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 settings, during the movement of the pushing cylinder 122, the sliding plates 1221 will move along the extending direction of the sliding grooves 105. Therefore, the sliding grooves 105 can guide the sliding plates 1221 and the pushing cylinder 122 in the vertical direction, so that the movement of the transmission mechanism 12 and the detection head 11 is more stable. Moreover, the sliding grooves 105 cooperating with the sliding plates 1221 can also limit the rotation of the pushing cylinder 122, thereby further improving the stability of the transmission mechanism 12 and the detection head 11 during the movement.

[0047] Please refer to Figure 3 and Figure 4 , in some embodiments, the first spring 13 is sleeved on the outer peripheries of the pushing 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 settings, the detection head 11 and the pushing cylinder 122 are located inside the first spring 13, which can not only save the space occupied by installing the first spring 13, but also improve the stability of the elastic force of the first spring 13 acting on the sliding plates 1221, which is beneficial to the transmission mechanism 12 to move stably in the vertical direction under the action of the first spring 13.

[0048] Please refer to Figure 8, in some embodiments, there are two gears 124 and four first mounting plates 123. Two of the first mounting plates 123 are arranged at intervals relative to each other, and the other two first mounting plates 123 are also arranged at intervals relative to each other. The two gears 124 are respectively arranged between two groups of two relatively arranged first mounting plates 123, and the gears 124 are rotatably connected to the two relatively arranged first mounting plates 123. There are four relief holes 1255 corresponding to the four first mounting plates 123. There are two second mounting plates 126, two second racks 128, and two first racks 127 corresponding to the two gears 124. Specifically, the four first mounting plates 123 are respectively inserted into the four relief holes 1255; a single second mounting plate 126 is located between two relatively arranged first mounting plates 123; on one side of each second mounting plate 126 facing the gear 124, there is a first rack 127 meshing with the gear 124; the two second racks 128 are both arranged at the bottom of the outer wall of the detection head 11 and respectively mesh with the two gears 124. Through the above settings, when the abutting cylinder 125 and the pushing cylinder 122 move relative to each other, the transmission cooperation among the first rack 127, the second rack 128, and the gear 124 is more stable, so that the relative movement between the abutting cylinder 125 and the pushing cylinder 122 is more stable, and further the stability of the detection head 11 during movement is improved.

[0049] Please refer to Figure 1 , a chamfer is provided at the edge of the top surface of the detection head 11, and the chamfer can facilitate the detection head 11 to pass through the top wall 101, so as to facilitate the detection head 11 to move out of the housing 10 for detection work.
