[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the expansion connection platform is set as a detachable structure, and the core component that can be detached to the left and right is set in the expansion connection platform, so that the expansion connection platform can be flexibly assembled under the first screw according to actual use requirements, and then the first screw barrel is engaged with the thread of the first screw, and the first screw is rotated to control the expansion connection platform to rise and fall.

[0019] 2. In the present invention, by opening a second screw hole corresponding to the first screw hole on the upper right end wall of the square rod, when the expansion connection platform moves to the limit position, the core component is driven by the first screw rod to idle, and the meshing of the first bevel tooth and the second bevel tooth, the meshing of the second gear and the first gear, and the transmission connection of the transmission belt can drive the spline barrel to rotate. Under the plugging of the spline shaft and the elastic support of the second spring, the cross pin head 2 will be embedded in the cross groove 2 opened at the end of the stud to drive the stud to rotate, driving the stud to be screwed into the second screw hole, the first screw hole and the second screw barrel at the same time, which can effectively improve the stability of the expansion connection platform installed above the square rod;

[0020] 3. In the present invention, by sliding the slider in the second screw hole, and with the help of the elastic support of the third spring, the meshing reversal of the first rack, the third gear and the second rack, and the elastic pulling of the tension spring on the bearing plate, when the stud is screwed into the second screw hole, the corresponding warning strip will move right and exit from the observation window, and when the stud exits the second screw hole, the corresponding warning strip will move left and fill in the observation window, so that the staff can judge the state of the reinforcement connection of the expansion connection platform by observing the position state of the warning strip, which improves the convenience of operation of the device in actual use to a certain extent;

[0021] 4. In the present invention, by setting the portion corresponding to the recess at the lower end of the first screw as a smooth structure, there is no external thread on this portion of the first screw, so that when the expansion connection platform is assembled and sleeved on the lower end of the first screw, there is no need to consider the meshing of the external thread on the first screw and the internal thread of the first screw barrel, which is conducive to ensuring the convenience of the expansion connection platform being spliced ​​and sleeved on the first screw.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Embodiment: This embodiment provides a modular connection expandable multifunctional intelligent integrated pole, see Figure 1 - Fig.12Specifically, it includes a square rod 1, a base 101 is fixedly installed at the bottom of the square rod 1, a stopper 102 is fixedly installed at the top right side of the square rod 1, a first screw rod 103 arranged parallel to the square rod 1 is rotatably installed between the base 101 and the stopper 102, and an expansion connection platform 2 is sleeved on the outer side of the first screw rod 103, and the expansion connection platform 2 includes a first shell 201 arranged on the left side, and a second shell 202 arranged on the right side, the left end wall of the first shell 201 is connected to the right end wall of the square rod 1 The end walls are slidably fitted, a cavity is opened at the center of the joint surface of the first shell 201 and the second shell 202, and a core component 203 is movably installed in the cavity, the core component 203 includes a first screw barrel 2031 that rotates vertically in the cavity, and the first screw barrel 2031 is threadedly sleeved on the outside of the first screw rod 103, a disk 2032 is fixedly installed at the bottom of the first screw barrel 2031, and a plurality of vertically arranged plug rods 2033 are inserted around the disk 2032, and the plurality of plug rods 203 The bottom end of the first screw 103 is fixed with a cross pin 2034 movably sleeved on the outside of the first screw rod 103, the bottom of the disc 2032 is surrounded by a plurality of first springs 2035 for elastically supporting the cross pin 2034, the upper outer end wall of the first screw barrel 2031 is coaxially fixed with a first bevel gear 2036, the core member 203 is vertically divided into left and right parts by the plane where the central axis of the first screw barrel 2031 is located, and the bottom of the cavity is provided with a cross pin 2034 adapted to the cross pin 2034. A cross groove 204 is provided, and insertion holes 205 are provided at the four corners of the splicing surface of the first shell 201. Second screw barrels 206 adapted to the insertion holes 205 are fixed at the four corners of the splicing surface of the second shell 202. A first screw hole 207 coaxially connected to each insertion hole 205 is provided through the first shell 201. An internal thread adapted to the first screw hole 207 is provided in the second screw barrel 206. A stud 208 is screwed together with the second screw barrel 206 and the first screw hole 207.

[0044] When the device is in use, the staff erects the device on the ground as a supporting structure for the lamp pole and various types of functional components. Afterwards, the staff can choose to install a corresponding number of expansion connection platforms 2 according to the number of functional components that actually need to be installed. The expansion connection platform 2 is connected from the lower end of the first screw rod 103, and a number of mounting holes are provided on the right end wall of the second shell 202. The staff can firmly connect different types of functional components to the expansion connection platform 2 through these mounting holes, and then drive the expansion connection platform 2 to carry the functional components fixedly connected thereto to the top of the square rod 1 with the help of the rotation of the first screw rod 103, so as to complete the modular installation of each functional component. Not only can the modular expansion connection of the functional components of the device be realized, but it is also more flexible when replacing the functional components in the later stage. There is no need to climb high, and the expansion connection platform 2 only needs to be controlled to rise up and down to realize the flexible replacement of the expanded functional components, which makes the operation safer and more convenient.

[0045] When the expansion connection platform 2 is mounted on the lower end of the first screw rod 103, the staff needs to rotate the stud 208 in advance, and drive the stud 208 to move left by means of the engagement of the stud 208 with the first screw hole 207 and the thread inside the second screw barrel 206. The right end of the stud 208 withdraws from the second screw barrel 206. After losing the connection with the stud 208, the first shell 201 and the second shell 202 can be separated. At this time, the left half of the core component 203 is located in the cavity on the right end wall of the first shell 201, and the right half of the core component 203 is located in the cavity on the right end wall of the first shell 201. The half part is located in the cavity on the left end wall of the second shell 202. Then the staff will put the separated expansion connection platform 2 on the lower end of the first screw 103 for reassembly. By rotating the stud 208 in the opposite direction, the stud 208 is screwed back into the second screw barrel 206 to complete the connection and fixation of the first shell 201 and the second shell 202, so that the left and right parts of the core component 203 are closed again and wrapped around the outside of the first screw 103. Then, the staff will install the functional components that need to be expanded on the expansion connection platform 2.

[0046] When the expansion connection platform 2 is in the process of moving upward under the square rod 1, under the elastic support of the first spring 2035, the cross pin head 2034 is tightly engaged in the cross groove 204 at the bottom of the cavity, which makes the core component 203 and the first shell 201 and the second shell 202 present an integrated structure. Under mutual restriction, the core component 203 in this state cannot rotate in the cavity. When the first screw rod 103 is driven to rotate, the first screw rod 103 is engaged with the first screw barrel 2031 to drive the core component 203 to move upward along the first screw rod 103, thereby controlling the expansion connection platform 2 and the functional components connected to the outside of the expansion connection platform 2 to move upward. When the expansion connection platform 2 moves upward to the limit position along the first screw rod 103, the stopper 102 or Under the obstruction of other expansion connection platforms 2 above, the expansion connection platform 2 in the rising state cannot continue to move. At this time, the positions of the first shell 201 and the second shell 202 are in an immovable state, so that the core component 203 in the cavity cannot continue to move upward. Under the threaded engagement of the first screw 103 and the first screw barrel 2031, when the first screw 103 continues to rotate, it will drive the first screw barrel 2031 to maintain a trend of synchronous rotation with the first screw 103 in the cavity, so that the cross pin head 2034 overcomes the elastic support of the first spring 2035 and withdraws from the bite with the cross groove 204, so that the core component 203 idles in the cavity, ensuring that the first screw 103 can continue to rotate, which is convenient for the staff to carry out subsequent rising installation of other expansion connection platforms 2.

[0047] When the staff needs to inspect and replace the functional components connected to the expansion connection platform 2 above the square rod 1, the staff can control the first screw 103 to reverse. At this time, the bottom of the lowest expansion connection platform 2 is unobstructed, and the friction resistance between the first screw 103 and the first screw barrel 2031 is less than the resistance of the first spring 2035 elastically supporting the cross pin head 2034 engaged in the cross groove 204, which makes the core component 203 relatively stable in the cavity and unable to rotate. With the help of the threaded engagement of the first screw 103 and the first screw barrel 2031, and the reversal of the first screw 103, the expansion connection platform 2 can be stably dropped downward along the first screw 103, and finally dropped to the bottom position of the square rod 1, so that the staff can stand on the ground to inspect and replace the functional components of the expansion connection on the expansion connection platform 2.

[0048] In the specific implementation process, Figure 1 and Figure 5As shown, a first worm gear 104 coaxially fixed to the outside of the first screw 103 is rotatably installed in the base 101, and a first worm 105 meshing with the first worm gear 104 is rotatably installed in the base 101, and one end of the first worm 105 extends through the outer end wall of the base 101 and is coaxially fixed with a first connector 106. When the device is in use, the staff can use an externally connected servo motor to drive the first screw 103 to rotate, and the drive shaft end of the servo motor is adapted to the first connector 106. In the process of driving the first screw 103 to rotate forward and reverse, the staff plugs the end of the servo motor drive shaft into the first connector 106, and then drives the servo motor to power on and start. After the servo motor driving shaft rotates, it will drive the first worm 105 to rotate synchronously. With the help of the meshing of the first worm 105 and the first worm wheel 104, the rotation of the first screw 103 is powered. Under the adaptive connection of the first connecting head 106, an external servo motor is used as the power source to drive the first screw 103 to rotate, so that the rotation of the first screw 103 drives the lifting operation of the expansion connection platform 2 to be more flexible and convenient, and with the help of the self-locking property of the one-way meshing transmission of the first worm 105 and the first connecting head 106, the first screw 103 cannot be driven to rotate by other external forces without the drive of an external servo motor, thereby improving the stability of the expansion connection platform 2 when it is installed above the square rod 1 to a certain extent.

[0049] In the specific implementation process, Figure 2 , Figure 4 , Figure 6 and Fig.10 As shown, both left and right ends of the stud 208 are provided with a second cross groove 209, and the upper right end wall of the square rod 1 is provided with a plurality of second screw holes 3 arranged corresponding to the first screw hole 207 in an orderly manner from top to bottom, a spline cylinder 301 coaxially arranged with the second screw cylinder 206 is rotatably installed in the second housing 202, and a spline shaft 302 is slidably inserted in the spline cylinder 301, and a cross pin 203 fixedly connected to the end of the spline shaft 302 is movably installed in the second screw cylinder 206, and the cross pin 203 is adapted to the second cross groove 209, and the outer side of the spline shaft 302 is movably installed. The movable sleeve is provided with a second spring 304 elastically supported between the spline cylinder 301 and the second cross pin head 303, a first gear 306 is coaxially fixed on the spline cylinder 301, a second bevel tooth 307 meshing with the first bevel tooth 2036 is rotatably installed in the second housing 202, and a second gear 308 meshing with the first gear 306 is coaxially fixed on the second bevel tooth 307, a transmission belt 305 is commonly connected to the transmission sleeve between the four spline cylinders 301 located in the same second housing 202, and the second gear 308 meshes with the first gear 306 on one of the spline cylinders 301.

[0050] When the device is in use, a second screw hole 3 corresponding to the first screw hole 207 is provided on the upper right end wall of the square rod 1. When the expansion connection platform 2 moves upward to the limit position under the rotation of the first screw rod 103, the first screw hole 207 provided on the first shell 201 will be aligned with the second screw hole 3. At this time, the first screw rod 103 continues to rotate. Although the expansion connection platform 2 cannot continue to move upward, the core component 203 will be driven by the first screw rod 103 to rotate in the cavity. Under the meshing of the first bevel tooth 2036 and the second bevel tooth 307, the meshing of the second gear 308 and the first gear 306, and the transmission connection of the transmission belt 305, the spline cylinder 301 is driven to rotate, and the spline cylinder During the rotation of 301, the spline shaft 302 inserted therein is driven to rotate. Since the cross pin head 303 will be embedded in the cross groove 209 provided at the end of the stud 208 under the elastic support of the second spring 304, the spline shaft 302 will drive the stud 208 to rotate during the rotation, and the stud 208 is driven to move to the left under the engagement of the threads, so that the stud 208 is simultaneously threadedly screwed into the second screw hole 3, the first screw hole 207 and the second screw barrel 206. By screwing the stud 208 into the corresponding second screw hole 3, the expansion connection platform 2 can be installed more firmly on the right end wall above the square rod 1, thereby further improving the stability of the device for the expansion connection of functional components.

[0051] When the first screw rod 103 is rotated in the reverse direction to control the expansion connection platform 2 to descend along the square rod 1, the screw 208 is screwed into the second screw hole 3, so that the expansion connection platform 2 cannot move downward immediately, and the core component 203 in the cavity cannot move downward. With the help of the threaded engagement between the first screw barrel 2031 and the first screw rod 103, the cross pin head 2034 overcomes the elastic support of the first spring 2035 and exits the engagement with the cross groove 204, so that the first screw rod 103 drives the core component 203 to rotate in the reverse direction in the cavity, driving the spline barrel 2031 to rotate in the reverse direction. 301 drives the second cross pin head 303 to reverse, and the part of the left end of the stud 208 screwed into the second screw hole 3 is screwed back into the first screw hole 207. With the help of the connection restriction between the expansion connection platform 2 and the top of the square rod 1, after the stud 208 withdraws from the second screw hole 3, the downward movement operation of the expansion connection platform 2 is no longer blocked. The staff controls the first screw rod 103 to rotate in the opposite direction, and can smoothly lower the expansion connection platform 2 from the top of the square rod 1 to the bottom, so as to facilitate the staff to inspect and replace the functional components of the expansion connection on the expansion connection platform 2 on the ground.

[0052] In the specific implementation process, Figure 7 , Fig.10 and Fig.12As shown, a slider 4 is slidably installed in the second screw hole 3, and a first rack 401 that is movably inserted into the square rod 1 is fixedly installed at the left end of the slider 4, and a third spring 402 for elastically supporting the slider 4 is movably sleeved on the outer side of the first rack 401, and the four second screw holes 3 corresponding to the four first screw holes 207 in the expansion connection platform 2 are set in the same group, and a plurality of bearing plates 405 are arranged in order from top to bottom in the square rod 1, and the bearing plates 405 are slidably installed in the square rod 1, and each of the bearing plates 405 corresponds to the four second screw holes 3 in the same group. It is arranged that a tension spring 406 for elastically pulling the supporting plate 405 is fixedly installed on the right inner end wall of the square rod 1, a warning strip 407 is fixedly installed on the left end wall of the supporting plate 405, and an observation window 408 corresponding to the warning strip 407 is opened on the right end wall of the square rod 1, a third gear 403 meshing with the first rack 401 is rotatably installed in the square rod 1, and a second rack 404 meshing with the third gear 403 is slidably installed in the square rod 1, and the second rack 404 is arranged parallel to the first rack 401 and points to the supporting plate 405.

[0053] When the device is in use, when the expansion connection platform 2 moves up to the extreme position, so that the stud 208 is screwed into the second screw hole 3 for reinforcement connection, the stud 208 screwed into the second screw hole 3 will push the slider 4 in the second screw hole 3 to move left, thereby driving the first rack 401 fixed at the left end of the slider 4 to move left, and with the meshing of the first rack 401 and the third gear 403, and the meshing of the third gear 403 and the second rack 404, the second rack 404 is driven to move rightward in the square rod 1. After the second rack 404 moves to the right, it gradually loses its resistance to the bearing plate 405. Under the elastic pulling of the tension spring 406, the bearing plate 405 moves rightward in the square rod 1, driving the warning strip 407 to withdraw from the observation window 408. When the stud 208 is not screwed into the second screw hole 3, under the elastic support of the third spring 402, the slider 4 drives the first rack 401 to move rightward to the rightmost position in the second screw hole 3. During this process, when the first rack 401, the third gear 403 and the second rack 404 are meshed, the second rack 404 moves leftward to the leftmost position, pushing the supporting plate 405 to move leftward, so that the warning strip 407 is embedded in the observation window 408. The outer surface of the warning strip 407 is attached with a conspicuous coating, which allows the staff to observe whether the warning strip 407 is in the observation window 408, thereby determining whether the stud 208 is screwed into the second screw hole 3, thereby ensuring the stability of the reinforced connection of the expansion connection platform 2 above the square rod 1.

[0054] In the specific implementation process, Figure 1 , Figure 2 and Fig. 9As shown, a recess 5 adapted to the first shell 201 is provided on the right end wall of the bottom of the square rod 1, and a through groove 501 penetrating into the recess 5 is transversely provided on the front and rear sides of the bottom of the square rod 1, and the through groove 501 is arranged corresponding to the first screw hole 207, and the outer surface of the lower end of the first screw rod 103 and the corresponding part of the recess 5 is set to a smooth structure, and two front-to-back symmetrical blocking blocks 502 are slidably inserted in the recess 5, and a blocking rod 503 adapted to the through groove 501 is fixedly connected to the blocking block 502, and magnetically attractive magnets 504 are fixedly installed in the front and rear blocking blocks 502.

[0055] When the device is in use, the recess 5 provided on the right end wall at the bottom of the square rod 1 can provide sufficient operating space for the installation of the first shell 201. At the same time, by penetrating the through groove 501 corresponding to the first screw hole 207 and provided in the recess 5, it is convenient for the staff to screw the stud 208 into the first screw hole 207 from the left side when assembling the expansion connection platform 2, which is conducive to ensuring the convenience of operation when the expansion connection platform 2 is assembled on the outer side of the lower end of the first screw rod 103. When the expansion connection platform 2 is assembled and sleeved on the outer side of the lower end of the first screw rod 103, the staff can insert the blocking block 502 into the recess 5, so that the blocking rod 503 is inserted into the through groove 501, so as to achieve the blocking of the recess 5 and the through groove 501. The magnets 504 that are magnetically attracted to each other in the two blocking blocks 502 can ensure the cooperation with the blocking rod 503, so as to ensure that the blocking block 502 is installed in the recess 5. Stability. After the blocking block 502 is loaded into the recess 5, the right end wall of the blocking block 502 is flush with the right end wall of the square rod 1, thereby ensuring the stability of the expansion connection platform 2 when it is lifted up. By setting the portion of the lower end of the first screw 103 corresponding to the recess 5 to a smooth structure, there is no external thread on this portion of the first screw 103. This makes it unnecessary to consider the meshing of the external thread on the first screw 103 and the internal thread of the first screw barrel 2031 when the expansion connection platform 2 is assembled and sleeved on the lower end of the first screw 103, thereby ensuring the convenience of operation of the expansion connection platform 2 spliced ​​and sleeved on the first screw 103. When the expansion connection platform 2 needs to be controlled to rise later, when the first screw 103 rotates, it is only necessary to slightly lift the expansion connection platform 2 upwards. During the rotation of the first screw 103, its external thread will automatically mesh with the internal thread of the first screw barrel 2031.

[0056] In the specific implementation process, Figure 2 , Figure 5 and Fig.12As shown, a second screw rod 6 arranged below the expansion connection platform 2 is inserted through the base 101, a third screw barrel 601 threadedly sleeved on the outside of the second screw rod 6 is rotatably installed in the base 101, a limit rod 602 arranged parallel to the second screw rod 6 is slidably inserted in the base 101, and the limit rod 602 is fixedly connected to the bottom of the second screw rod 6, a second worm gear 603 is coaxially fixed on the outside of the third screw barrel 601, a second worm 604 meshing with the second worm gear 603 is rotatably installed in the base 101, a storage cavity 605 is opened on the right end wall of the base 101, a movable door 606 covering the storage cavity 605 is rotatably installed on the right end wall of the base 101, the second worm 604 movably penetrates into the storage cavity 605, and a second connecting head 607 is fixedly installed, and a crank 608 adapted to the second connecting head 607 is placed in the storage cavity 605.

[0057] When the device is in use, the staff can drive the third screw barrel 601 to rotate, and with the help of the threaded engagement of the third screw barrel 601 and the second screw rod 6, and the restriction of the second screw rod 6 by the up and down sliding of the limit rod 602, the second screw rod 6 can be moved up and down, and then the expansion connection platform 2 is lifted upward, to assist the engagement of the first screw barrel 2031 in the core component 203 in the expansion connection platform 2 with the external thread on the first screw rod 103. During this process, the staff can plug the crank 608 into the second connecting head 607, and then hold the crank 608 to rotate, apply rotational power to the second worm 604, and transmit the rotational power to the third screw barrel 601 with the help of the engagement of the second worm 604 with the second worm wheel 603, which can effectively improve the operational convenience of the device during actual use.

[0058] Specifically, the working principle and operation method of the present invention are as follows:

[0059] The staff rotates the stud 208 to drive it out of the second screw barrel 206, so that the expansion connection platform 2 is split into two parts, and then the staff reassembles the split expansion connection platform 2 on the lower end of the first screw 103, and screws the stud 208 back into the second screw barrel 206, so that the expansion connection platform 2 is reconnected into a whole. In this state, the core component 203 is sleeved on the outside of the first screw 103. Then the staff connects the functional components to the expansion connection platform 2. The staff drives the first worm 105 to rotate through an external servo motor, and drives the first screw 103 to rotate by means of the engagement of the first worm 105 and the first worm wheel 104. The staff plugs the crank 608 into the second connector 607 and holds the crank. The rotation of 608 drives the second worm 604 to rotate, and with the help of the meshing of the second worm 604 and the second worm wheel 603, the third screw barrel 601 is driven to rotate, and with the help of the meshing of the third screw barrel 601 and the second screw 6, and the up and down sliding restriction of the limit rod 602, the second screw 6 is driven to move upward, and the expansion connection platform 2 is lifted upward. After the position of the expansion connection platform 2 is lifted, the thread inside the first screw barrel 2031 is adaptively meshed with the thread outside the first screw 103. In this state, with the help of the elastic support of the first spring 2035, the cross pin head 2034 is engaged in the cross groove 204, and the thread engagement resistance between the first screw 103 and the first screw barrel 2031 is less than the first spring 2035 on the cross pin head 2034. The elastic supporting force makes the core piece 203 remain in a state of being unable to rotate on the expansion connection platform 2. The first screw 103 continues to rotate, driving the expansion connection platform 2 to move upward. When the expansion connection platform 2 moves up to the limit position, the core piece 203 cannot continue to move upward relative to the first screw 103. Under the continuous rotation of the first screw 103, the cross pin 2034 will overcome the elastic support of the first spring 2035 and release the engagement with the cross groove 204. At this time, the core piece 203 is driven by the first screw 103 to rotate in the expansion connection platform 2. With the meshing of the first bevel tooth 2036 and the second bevel tooth 307, the meshing of the second gear 308 and the first gear 306, and the transmission connection of the transmission belt 305, it can The spline cylinder 301 is driven to drive the cross pin head 2 303 to rotate. Under the elastic support of the second spring 304, the cross pin head 203 is embedded in the cross groove 209 at the right end of the stud 208, driving the stud 208 to rotate, driving the stud 208 to move left and screw into the second screw hole 3. In this state, the slider 4 is pushed to move left, and the meshing reversal of the first rack 401, the third gear 403 and the second rack 404 is used to make the second rack 404 move right, releasing the support for the bearing plate 405. Under the elastic pulling of the tension spring 406, the bearing plate 405 drives the warning strip 407 to move right. The staff observes that the warning strip 407 withdraws from the observation window 408 and judges that the expansion connection platform 2 is firmly installed above the square rod 1.

[0060] When the staff controls the first screw 103 to rotate in the opposite direction, in the initial state, it will drive the core component 203 to rotate in the opposite direction in the expansion connection platform 2, drive the spline cylinder 301 to drive the spline shaft 302 to reverse, and control the stud 208 to move to the right and withdraw from the second screw hole 3. At this time, the downward movement restriction of the expansion connection platform 2 is released, and the cross pin head 2034 is re-engaged in the cross groove 204 under the elastic support of the first spring 2035. Subsequently, under the continuous reversal of the first screw 103, with the help of the engagement of the first screw 103 and the first screw cylinder 2031, the expansion connection platform 2 is controlled to fall stably to the bottom of the square rod 1, which is convenient for the staff to inspect and replace the functional components of the expansion connection of the expansion connection platform 2.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
