Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of photographic equipment and mobile phone accessories, and in particular to an automatic telescopic component and a supporting tripod. Background Art

[0002] This section introduces the background technology that may be related to various aspects of the embodiments of the present invention to the readers, and is believed to provide the readers with useful background information, thereby helping the readers to better understand various aspects of the embodiments of the present invention. Therefore, it can be understood that the description in this section is for the above purpose and does not constitute an admission of the prior art.

[0003] A tripod is a support frame used to stably support equipment. Currently, tripods are often used in technical fields such as photography, surveying and mapping, medical equipment, industrial instruments, and home furnishings. Tripods are generally used to place cameras, lamps, reflectors, measuring and mapping instruments, and other equipment that require stability to avoid human factors affecting the photography or measurement results. Existing tripods all include three legs, but in order to ensure stability and increase the height adjustment, the telescopic rods on the three legs can be freely retracted. The height of the tripod needs to be adjusted to meet different shooting requirements, and the height is also adjusted in conjunction with the vertical telescopic support rod on the top.

[0004] According to different usage environments, users can adjust the height and stability of the tripod as needed. During installation, in order to ensure the flatness of the upper end surface, it is necessary to manually adjust the length of the telescopic rods on the three supporting legs. The manually adjusted tripod is far less accurate than the automatic adjustment, which is time-consuming and labor-intensive and seriously affects the accuracy of the work data and results. Most of the automatic telescopic rods used in tripods on the market are two-section telescopic rods. When fully retracted, the minimum length is relatively large, which is not conducive to some occasions with simple designs and strictly limited space. Multi-section automatic telescopic devices have problems such as complex structure, cumbersome processing, and large usage space. Therefore, it is very necessary to obtain an automatic telescopic rod and automatic bracket with a simple structure and space saving. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic telescopic component, comprising: a base portion 1, a telescopic accommodating section 2 is connected to the base portion 1, and at least one telescopic section 3 is connected to the telescopic accommodating section 2; the base portion 1 is provided with a driving mechanism 11, and a accommodating space 20 for accommodating the telescopic section 3 is provided in the telescopic accommodating section 2; a driving rod 21 is provided in the telescopic accommodating section 2, which is transmission-connected to the driving mechanism 11, and a driving thread is provided on the driving rod 21; a telescopic section support component 32 is provided at the bottom of the telescopic section 3, and a telescopic thread matching the driving thread is provided on the telescopic section support component 32; the driving mechanism 11 drives the driving rod 21 to rotate, and the driving rod 21 drives the telescopic section support component 32 to rise and fall, and the telescopic section support component 32 drives the telescopic section 3 to telescope within the length range of the telescopic accommodating section 2. The following is a detailed description of an automatic telescopic component provided by an embodiment of the present invention.

[0044] like Figures 1 to 8 As shown, in an embodiment of the present invention, in an embodiment of the present invention, the driving rod 21 can optionally adopt a solid screw rod, and an external thread is provided on the driving rod 21. The telescopic thread provided on the telescopic section support component 32 is an internal thread, and the internal thread cooperates with the external thread. The driving rod 21 rotates to make the telescopic section support component 32 telescopically move within the length range of the telescopic accommodating section 2.

[0045] like Figures 2 to 7As shown, in the embodiment of the present invention, a telescopic section connecting component 33 for driving an adjacent telescopic section 3 is further provided in the telescopic section 3, and the telescopic section connecting component 33 is movably connected with the driving rod 21; a transmission rod 31 is provided on the telescopic section connecting component 33, and a transmission thread is provided on the transmission rod 31; a telescopic section supporting component 32 is provided at the bottom of the adjacent telescopic section 3, and a telescopic thread matching the transmission thread is provided on the telescopic section supporting component 32; the driving rod 21 drives the telescopic section connecting component 33 to rotate, and the telescopic section connecting component 33 drives the transmission rod 31 to rotate, and the transmission rod 31 drives the telescopic section support component 32 of the adjacent telescopic section 3 to rise and fall, and the telescopic section support component 32 drives the adjacent telescopic section 3 to extend and retract within the length range of the telescopic section 3. In the embodiment of the present invention, the transmission rod 31 may be a hollow screw tube, the transmission thread provided on the transmission rod 31 is an external thread, and the telescopic thread provided on the telescopic section support component 32 is an internal thread. The driving rod 21 rotates to make the telescopic section support component 32 move up and down. At the same time, the telescopic section connecting component 33 rotates under the drive of the driving rod 21, driving the telescopic section support component 32 of the adjacent telescopic section to telescopically move within the length range of the telescopic accommodating section 2. In order to better transmit the driving force, the driving rod 21 is coaxial with the transmission rod 31, and the transmission rod 31 is provided with a hollow chamber 310 for accommodating the driving rod 21. While the telescopic section support component 32 telescopically moves within the length range of the telescopic accommodating section 2, the telescopic section support component 32 of the adjacent telescopic section telescopically moves within the length range of the telescopic accommodating section 2. When retracted, the driving rod 21 is accommodated in the hollow chamber 310. At the same time, the transmission rod 31 of the telescopic section 3 will also be accommodated in the hollow chamber 310 in which the transmission rod 31 of the next telescopic section 3 is arranged, and the telescopic sections 3 do not interfere with each other.

[0046] like Figure 7-Figure 9As shown, in the embodiment of the present invention, a D-shaped hole 34 is provided on the telescopic joint connecting part 33, and an orientation position 24 matching the D-shaped hole 34 is provided on the driving rod 21, and the driving rod 21 passes through the D-shaped hole 34.

The orientation position 24 provided on the driving rod 21 matches the D-shaped hole 34, and while the driving rod 21 drives the telescopic joint supporting part 32 to rise and fall, the driving rod 21 drives the telescopic joint connecting part 33 to rotate. The driving rod 21 drives the telescopic joint connecting part 33 to rotate, and at the same time, the driving rod 21 shuttles in the D-shaped hole 34. The rotation of the telescopic joint connecting part 33 also drives the telescopic joint connecting part 33 of the adjacent telescopic joint 3 to rotate through the transmission rod 31. Of course, it can be understood that the embodiment of the present invention is not limited to this, and the D-shaped hole 34 and the driving rod 21 can be movably connected in other ways. For example, the D-shaped hole is modified into a polygon or a protrusion is provided at the position of the circular hole, and a groove matching the protrusion is provided on the driving rod 21, and the extension length of the groove is equivalent to the length range of the telescopic accommodating section 2. In short, as long as the transmission mode of the telescopic section support component 32 and the driving rod 21 is not affected and the matching scheme that can also drive the telescopic section connecting component 33 to rotate can be realized.

[0047] In the embodiment of the present invention, Figure 7-10 As shown, in the embodiment of the present invention, in order to prevent the expansion joint connection part 33 from rotating and rubbing against the expansion joint support part 32, thereby affecting the transmission efficiency, the expansion joint 3 further includes an expansion joint bearing 300 sleeved outside the driving rod 21, and the expansion joint bearing 300 is fixed on the expansion joint support part 32. In order to prevent the expansion joint bearing 300 from loosening, the expansion joint bearing 300 is fixed on the expansion joint support part 32 by a retaining spring.

A D-shaped hole 34 is provided on the top support component 42, and a directional position matching the D-shaped hole 34 is provided on the transmission rod 31, and the transmission rod 31 passes through the D-shaped hole 34. The rotation of the telescopic section connecting component 33 also drives the adjacent top support component 42 to telescopically move within the length range of the last section of the telescopic section 3 through the transmission rod 31. In order to effectively ensure the telescopic movement of the telescopic section 3 and the top support section 4, a receiving space 30 for accommodating the adjacent telescopic section 3 or the top support section 4 is provided in the telescopic section 3. A receiving space 40 for the contracted transmission rod 31 of the adjacent telescopic section 3 is provided in the top support component 42.

The telescopic accommodating outer tube 26, the telescopic outer tube 36, and the top support outer tube 46 can be cylindrical or prismatic. In the embodiment of the present invention, the shape of the transmission rod 31 can be set with a corresponding orientation position with reference to the driving rod 21.

[0049] like Figure 7-Figure 8 As shown, in the embodiment of the present invention, in order to increase stability, a telescopic accommodating section support component 22 is provided at the bottom of the telescopic accommodating section 2. In order to prevent the rotation of the drive rod 21 and the friction between the telescopic accommodating section support component 22 and the influence of transmission efficiency, the telescopic accommodating section 2 also includes a bearing 200 sleeved outside the drive rod 21, the bearing 200 is fixed on the telescopic accommodating section support component 22, and the telescopic accommodating section support component 22 is connected to the base part 1. In order to prevent the bearing 200 from loosening, the section bearing 200 is fixed on the telescopic accommodating section support component 22 by a retaining spring. The driving mechanism 11 is connected to the driving rod 21 through a speed reduction mechanism 12, and the driving mechanism 11 can be a motor. Of course, it can be understood that the present invention is not limited to this, and the driving mechanism can be other driving devices that make the driving rod 21 rotate forward and reverse, which can still be realized. In order to increase stability, a power supply battery 10 is provided in the base part, and the power supply battery 10 is arranged below the driving mechanism 11. The power supply battery 10 is used to supply power to the driving mechanism 11, and at the same time, it also plays a certain counterweight role. Of course, it can be understood that the embodiments of the present invention are not limited to this, and the driving method of the driving mechanism 11 can also be implemented by adopting the existing plug-in power supply method, which will not be described in detail here.

[0050] To further demonstrate the advanced nature of the automatic telescopic component provided by the embodiment of the present invention, the embodiment of the present invention also provides a supporting tripod, such as Fig.11 As shown, the supporting tripod includes a vertical supporting column 7 and a plurality of inclined supporting columns 8, wherein the vertical supporting column 7 is connected to the top of the inclined supporting column 8 via a connecting seat 9; the vertical supporting column 7 is arranged on the top of the connecting seat 9, and the top of the inclined supporting column 8 is evenly hinged at the circumferential position of the connecting seat 9; the vertical supporting column 7 and / or the inclined supporting column 8 are the automatic telescopic components.

[0051] In summary, the embodiment of the present invention provides an automatic telescopic component and a supporting tripod, which drives the telescopic section support component of the telescopic section to rise and fall by rotating the driving rod, and the telescopic section support component drives the telescopic section to telescope within the length range of the telescopic accommodating section. At the same time, the telescopic section connecting component in the telescopic section and the transmission rod rotate downward, driving the telescopic section support component of the adjacent telescopic section to telescope within the length range of the telescopic accommodating section, thereby realizing the extension or contraction of the automatic telescopic component, which can automatically extend or contract the corresponding length according to actual needs, has the characteristics of simple structure and convenient folding and unfolding, which improves the convenience of use, and can be widely used in technical fields such as photography, surveying and mapping, medical treatment, industrial instruments, and home furnishings, which is conducive to market promotion and use.
