DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0036] Example

[0037] like Figure 1 As shown, the present invention includes a plurality of support legs 1 and a fixing frame 7, wherein the support legs 1 are hinged to the fixing frame 7, and a driving assembly 5 is further provided on the fixing frame 7, wherein the driving assembly 5 is used to drive the support legs 1 to rotate around a hinge point with the fixing frame 7; a fixing piece is provided at the bottom of one of the support legs 1, and universal wheels 2 are provided at the bottom of the remaining support legs 1.

[0038] In view of the fact that cameras are usually needed to collect image data in the existing industrial Internet of Things, and cameras are usually fixed at the use area using a tripod, but the existing tripod needs to be opened manually when in use, and after use, the opened tripod needs to be retracted manually, which makes the tripod more inconvenient to use. For this reason, the technical solution is provided with a driving assembly 5 on the existing tripod, and the angle formed between each support leg 1 and the fixing frame 7 can be adjusted by the provided driving assembly 5, so as to achieve the purpose of spreading the tripod; at the same time, in order to ensure that the provided support legs 1 can be stably spread in the working area, a fixing piece is provided at the bottom of one of the support legs 1, and the fixing piece is hinged to the support leg 1, and universal wheels 2 are provided at the bottom of the remaining support legs 1. In this way, the provided fixing piece can not only prevent the support leg 1 from tilting during the opening or contraction process, and improve the stability of the tripod when in use, but also ensure that the tripod is retracted near the fixing piece by the provided fixing piece, so as to achieve a certain restraining force on the tripod so that it can be reused next time.

[0039] The driving assembly 5 includes a driving mechanism 9, a threaded rod 11, a movable disk 10, and movable rods 4 having the same number as the supporting legs 1; the driving mechanism 9 is fixed on the fixing frame 7, the threaded rod 11 is connected to the output section of the driving mechanism 9, the movable disk 10 is sleeved on the threaded rod 11, and the movable disk 10 is connected to the threaded rod 11 by threads. One end of the movable rod 4 is hinged to the movable disk 10, and the other end is hinged to the supporting leg 1.

[0040] In this embodiment, in order to ensure that the provided driving assembly 5 can drive the smooth opening of each supporting leg 1, the provided driving assembly 5 includes a driving mechanism 9, a threaded rod 11, a movable disk 10, and movable rods 4. Among them, the provided driving mechanism 9 is a motor. When it is necessary to open the supporting leg 1, the driving mechanism 9 rotates forward. Since the movable disk 10 is connected to the threaded rod 11 by threads, the movable disk 10 on the threaded rod 11 can move downward on the threaded rod 11. When the movable disk 10 moves downward, it will drive the movable rod 4 to move synchronously, thereby pushing the supporting leg 1 to rotate around the hinge with the fixing frame 7, achieving the purpose of opening each supporting leg 1; when it is necessary to retract the tripod after use, the driving mechanism 9 is rotated in the reverse direction to force the movable disk 10 to move upward, so that the movable rod 4 pulls the opened supporting leg 1 to retract.

[0041] The driving assembly 5 further includes a sleeve 6. The sleeve 6 is sleeved on the threaded rod 11, and a bearing connected to the threaded rod 11 is provided inside the sleeve 6; a plurality of strip-shaped openings having the same number as the movable rods 4 are provided on the circumferential side wall of the sleeve 6, and the strip-shaped openings are distributed along the axial direction of the sleeve 6. The movable disk 10 is provided with lug ears hinged to the movable rods 4, and the lug ears are located inside the strip-shaped openings.

[0042] In this embodiment, in order to ensure that when the driving mechanism 9 drives the threaded rod 11 to rotate, the movable disk 10 sleeved on the threaded rod 11 rotates synchronously with the threaded rod 11 under the action of frictional resistance, so that the movable rods 4 are twisted at the hinges with the movable disk 10 and the supporting legs 1 respectively, and the hinges of the movable rods 4 are broken after long-term use. For this reason, in this technical solution, a sleeve 6 is further sleeved on the threaded rod 11, and strip-shaped openings having the same width as the lug ears are also provided on the side wall of the sleeve 6. In this way, when the threaded rod 11 rotates, the movable rods 4 can be restricted to a certain extent under the action of the strip-shaped openings, thereby avoiding the twisting of the movable rods 4 and improving the service life of the movable rods 4.

[0043] The fixing member includes a fixing box 3 and a connecting rod 18. One end of the connecting rod 18 is rotatably connected to the fixing box 3, and the other end is hinged to the supporting leg 1.

[0044] In this embodiment, in order to ensure that the fixing device can stably constrain one of the supporting legs 1, the fixing device includes a fixing box 3 and a connecting rod 18. The fixing box 3 is provided with a mounting hole 14 for mounting bolts. The fixing box 3 can be fixed to the ground in use by bolts to prevent the fixing box 3 from moving. At the same time, in order to ensure that the supporting leg 1 can be smoothly opened and contracted, a connecting rod 18 for being hinged to the supporting leg 1 is provided in the fixing box 3.

[0045] The fixing box 3 is also provided with a cavity, and the side wall of the connecting rod 18 in the cavity is provided with a plurality of blades 19; the fixing box 3 is also provided with an air inlet 28 and an air outlet 27 connected to the cavity; and also includes a fluid medium generating device, which is connected to the air inlet 28.

[0046] When each supporting leg 1 is opened by using the driving mechanism, when there are impurities on the ground of the working area that block the universal wheel 2, the supporting leg 1 in a certain direction cannot continue to move smoothly in the working area. For this reason, the present embodiment provides a cavity in the fixing box 3, and a plurality of blades 19 connected to the connecting rod 18 are provided in the cavity. In this way, when the fluid medium generating device delivers a certain amount of pressurized gas into the air inlet 28, the pressurized gas enters the cavity and acts on the blades 19, forcing the blades 19 to drive the connecting rod 18 to rotate in the cavity, thereby allowing the supporting leg 1 connected to the connecting rod 18 to rotate in a horizontal plane, and finally allowing the universal wheel 2 that was originally blocked by impurities to be staggered, thereby ensuring that each supporting leg 1 can be opened smoothly.

[0047] The fluid medium generating device comprises a first airbag component 12 and a second airbag component 13, wherein the first airbag component 12 and the second airbag component 13 are both sleeved on the threaded rod 11, and the first airbag component 12 and the second airbag component 13 are respectively located at the upper and lower ends of the movable disk 10, and a one-way valve is arranged on the second airbag component 13, and the one-way valve can ensure that the outside air can enter into the second airbag component 13, while the air in the second airbag component 13 cannot be discharged through the one-way valve; a first mounting cavity 16 and a second mounting cavity are also arranged on the fixing box 3, and the second airbag component 13 is connected with one end of the first mounting cavity 16 through a first air pipe, and the air inlet 28 is connected with the other end of the first mounting cavity 16; one end of the second mounting cavity is connected with the air inlet, and the other end is connected with the first airbag component 12 through a second air pipe, and the second mounting cavity is also provided with a blocking component 20 for blocking the air inlet.

[0048] In this embodiment, the fluid medium generating device is the first airbag member 12 and the second airbag member 13. Preferably, both the first airbag member 12 and the second airbag member 13 are corrugated pipes made of rubber material, and they can deform axially along the threaded rod 11. Therefore, when the movable disk 10 located on the threaded rod 11 compresses the first airbag member 12 or the second airbag member 13, the air inside can be squeezed out, thereby generating a certain pressure gas acting on the blade 19, forcing the blade 19 to drive the connecting rod 18 to rotate.

[0049] When the tripod is normally opened, the driving mechanism drives the movable disk 10 to move downward. When the movable disk 10 moves downward, it will squeeze the second airbag member 13, so that the air located in the second airbag member 13 enters the first installation cavity 16 through the first air pipe, and then the gas enters the first airbag member 12 through the second air pipe, ensuring that the movable disk 10 can normally pull the first airbag member 12 to stretch when moving downward.

[0050] In this embodiment, in order to prevent the gas inside the second airbag member 13 from acting on the blade 19 through the air inlet during the extrusion process, a blocking member 20 for blocking the air inlet is further provided in the second installation cavity. When the second airbag member 13 is squeezed, the provided blocking member 20 can prevent the gas entering the second installation cavity from acting on the blade 19 through the air inlet; and when the first airbag member 12 is squeezed, the blocking member can open the air inlet, so that the gas generated by the extrusion of the first airbag member 12 can act on the blade 19 through the air inlet, realizing the rotation of the connecting rod 18, adjusting the position of the support leg 1 in the working area, so that the universal wheel 2 can smoothly bypass the obstacle, ensuring that the tripod can be normally opened.

[0051] The blocking member 20 includes a blocking rod 21 and a first elastic member. One end of the first elastic member is connected to the inner wall of the second installation cavity, and the other end is connected to the blocking rod 21. The outer diameter of the blocking rod 21 is the same as the inner diameter of the second installation cavity. Both ends of the blocking rod 21 are respectively provided with a first connection hole and a second connection hole 23 that communicate with each other. The inner diameter of the first connection hole is larger than the inner diameter of the second connection hole 23; a fixed disk 25, a second elastic member 26, and a blocking block 24 are provided in the first connection hole. One end of the second elastic member 26 is connected to the fixed disk 25, and the other end is connected to the blocking block 24. The second elastic member 26 is used to push the blocking block 24 to block the second connection hole 23.

[0052] A vertical rod with an outer diameter smaller than the inner diameter of the second connection hole 23 is further provided in the air inlet 28, and a third connection hole 22 is further provided on the side wall of the blocking rod 21. The third connection hole 22 communicates the first installation cavity 16 with the second connection hole 23

[0053] In the initial state of this embodiment, under the action of the first elastic member, the plugging rod 21 does not extend into the air inlet. At this time, the plugging rod 21 plugs the second connection hole 23 under the action of the second elastic member 26. Therefore, when the second airbag member 13 is squeezed, the gas inside the second airbag member 13 enters the second installation cavity. Since the plugging rod 21 is in a plugged state, the gas entering the second installation cavity will push the plugging rod 21 to move towards the air inlet 28. Eventually, the vertical rod extends into the second connection hole 23 and pushes the plugging block 24 to compress the second elastic member 26, opening the second connection hole 23. At this time, the air squeezed and transferred from the second airbag member 13 to the second installation cavity will sequentially pass through the second connection hole 23 and the third connection hole 22 into the first installation cavity 16, and finally enter the first airbag member 12; when the support leg 1 is opening and the universal wheel 2 encounters an obstacle, the driving mechanism 9 is used to drive the movable disk 10 to move upward to squeeze the first airbag member 12. When the first airbag member 12 is squeezed, the gas inside it enters the first installation cavity 16. At the same time, when the movable disk 10 moves upward, it pulls the second airbag member 13 to stretch, generating a negative pressure inside. Under the action of the first elastic member, the plugging rod 21 is pulled upward to open the originally plugged air inlet 28. Furthermore, the gas squeezed by the first airbag member 12 subsequently acts on the blade 19 through the air inlet 28 to drive the connecting rod 18.

[0054] In another embodiment, grooves are provided on both sides of the inner wall of the second installation cavity. A third elastic member 17 and a plugging plate 15 are provided in the grooves. The third elastic member 17 can push the two plugging plates 15 to move closer to the middle to plug the second installation cavity; bevels are provided on the plugging plates 15. When the two plugging plates 15 move closer, the bevels on the two plugging plates 15 can form a V-shaped structure.

[0055] In this embodiment, in order to prevent the air transferred from the first airbag member 12 into the air inlet 28 from entering the plugging rod 21, a plugging plate 15 is further provided. When the first elastic member pulls the plugging rod 21 back into the second installation cavity, the two plugging plates 15 can plug the second installation cavity below the plugging rod 21 to prevent the air entering the air inlet from leaking through the plugging rod 21; when the plugging rod 21 moves downward, the lower end of the plugging rod 21 acts on the inclined surface of the plugging plate 15, forcing the plugging plate 15 to retreat towards the third elastic member 17, thus ensuring that the plugging rod 21 can smoothly enter the air inlet.

[0056] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
