Description

Technical Field

[0001] This invention relates to the field of photographic equipment technology, and more particularly to a telescopic bracket and a photographic equipment assembly having the telescopic bracket. Background Technology

[0002] Telescopic tripods can support photographic equipment such as cameras, camcorders, monitors, and fill lights, and can adjust their height, improving the stability of the equipment during use. Existing telescopic tripods include single-leg and tripod types. Each leg typically has multiple tubes that fit together, along with locking devices between adjacent tubes. The adjacent tubes can be adjusted vertically, and their relative positions are locked by the locking devices. Adjusting the height of the telescopic tripod requires manually loosening the locking devices first, then extending and retracting the multiple tubes, and finally manually tightening the locking devices to lock their relative positions. This makes the telescopic tripod's extension and retraction complex, time-consuming, and laborious, and may even cause you to miss the optimal shooting opportunity at crucial moments.

Detailed Implementation

[0033] To make the objectives and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0034] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a telescopic bracket 200 for photographic equipment, comprising a tube assembly 3, a locking assembly 2 disposed on the tube assembly 3, a support assembly 1 mounted on the locking assembly 2, and a linkage assembly 4 disposed in the tube assembly 3. The support assembly 1 is used to mount photographic equipment (e.g., monitors, cameras, camcorders, etc.). In this embodiment, the support assembly 1 includes a connecting seat 12 mounted on the upper end of the locking assembly 2 and a pan / tilt head 11 detachably mounted in the connecting seat 12. Preferably, the photographic equipment is pre-attached to the pan / tilt head 11. In use, the photographic equipment pre-attached to the pan / tilt head 11 can be quickly connected to the connecting seat 12 to achieve mounting of the photographic equipment on the telescopic bracket 200. The connecting seat 12 and the pan / tilt head 11 can adopt existing or later constructions, which will not be described in detail here. The tube assembly 3 includes a plurality of branch tubes that are movable relative to each other. Preferably, the tube assembly 3 includes a first branch tube 31, a second branch tube 32 movably connected to the first branch tube 31, and a third branch tube 33 movably connected to the second branch tube 32. Here, we will take a pipe assembly 3, which includes three branch pipes, as an example for explanation. In this embodiment, the first branch pipe 31, the second branch pipe 32, and the third branch pipe 33 are all irregularly shaped pipes. The first branch pipe 31 is fitted into the second branch pipe 32 through a first connecting sleeve 34, and the second branch pipe 32 is fitted into the third branch pipe 33 through a second connecting sleeve 35. The locking component 2 can lock and unlock the connection between the first branch pipe 31, the second branch pipe 32, and the third branch pipe 33 of the pipe assembly 3, and with the cooperation of the linkage component 4, it can enable the user to adjust the height of the pipe assembly 3 as needed.

[0035] In this embodiment, the locking assembly 2 includes a housing 21, a drive assembly 22, a first base 23, a locking member 24, and a second base 26. (See also...) Figures 2 to 6 The housing 21 is mounted on the upper end of the first branch pipe 31 of the pipe assembly 3. Preferably, the upper end of the first branch pipe 31 extends partially into the housing 21. Some components of the drive assembly 22 are disposed in the housing 21, and some components are disposed in the first branch pipe 31. The first base 23 is fixed at the lower end of the first branch pipe 31. The locking member 24 is disposed in the drive assembly 22 and is movable relative to the drive assembly 22. The second base 26 is mounted on the first base 23, that is, the first branch pipe 31, the first base 23, and the second base 26 are fixed relative to each other. The drive assembly 22 passes vertically through the first branch pipe 31 and the first base 23 and extends into the second base 26.

[0036] The drive assembly 22 includes a drive member 221 mounted in the housing 21, a rod 222 that can be pushed by the drive member 221, a first elastic member 224 sleeved outside the upper axial end of the rod 222 and abutting against the drive member 221, and a locking seat 223 connected to the lower axial end of the rod 222. One end of the drive member 221 is rotatably disposed in the housing 21, and the other end extends out of the housing 21. Preferably, the drive member 221 is generally L-shaped. The L-shaped drive member 221 includes a horizontal portion disposed in the housing 21 and a vertical portion disposed outside the housing 21. When the drive member 221 is in the locked position, its horizontal portion is inclined upward, and when the drive member 221 is in the unlocked position, its horizontal portion is horizontal. In this embodiment, the vertical portion of the drive member 221 is configured as a wrench, allowing the user to unlock the tube assembly 3 by pressing the vertical portion of the drive member 221 and lock the tube assembly 3 by releasing the drive member 221. The first elastic element 224 abuts against the driving element 221 to automatically push the driving element 221 from the unlocked position to the locked position. In this embodiment, the first elastic element 224 is a spring. The first elastic element 224 is positioned in a sleeve 226 installed in the upper end of the first branch pipe 31 of the pipe assembly 3. The sleeve 226 is hollow, and its inner side is configured as a stepped hole 2261. The first elastic element 224 is at least partially installed in the stepped hole 2261. A radially outwardly extending flange 2262 is provided on the outer side of the upper end of the sleeve 226. The flange 2262 presses against the upper end of the first branch pipe 31 to position the sleeve 226 in the axial direction. Preferably, a stop 225 is installed at the position where the driving element 221 abuts against the first elastic element 224. The stop member 225 is installed in the drive member 221 via a threaded connection. The stop member 225 can adjust its protrusion height relative to the drive member 221 to compensate for assembly errors between the drive member 221 and the first elastic member 224. The two axial ends of the rod member 222 extend beyond the two axial ends of the first branch pipe 31, respectively. In this embodiment, the rod member 222 passes through the stepped hole 2261 of the sleeve 226, extends downward to the first base 23, and exits from the first base 23 into the second base 26. Preferably, the upper axial end of the rod member 222 abuts against the stop member 225 below the drive member 221. The lower axial end of the rod member 222 is mounted on the locking seat 223 via a connecting pin 227. The locking seat 223 is located between the first base 23 and the second base 26 and is movable relative to the first base 23 and the second base 26.

[0037] In this embodiment, the locking seat 223 is hollow. The locking seat 223 includes a locking seat body 2230, at least one slot 2232, at least one through hole 2233, and a connecting post 2234. The locking seat body 2230 is generally hollow and cylindrical. The inner side of the locking seat body 2230 is provided with a mating hole 2231 for mating with the lower part of the first base 23. The at least one slot 2232 is formed on the peripheral wall of the locking seat body 2230, with its opening facing downwards. The at least one through hole 2233 is provided on the peripheral wall of the locking seat body 2230 and penetrates the peripheral wall of the locking seat body 2230 along its radial direction. In this embodiment, the at least one slot 2232 includes three slots. The three slots 2232 are arranged at equal intervals along the circumference of the locking seat body 2230. The at least one through hole 2233 includes three through holes. Three through holes 2233 are arranged at equal intervals along the circumference of the locking seat body 2230; preferably, a through hole is provided between two adjacent slots 2232. The locking member 24 is disposed in the through hole 2233. The locking member 24 is a locking block, which engages in the through hole 2233. The connecting post 2234 is disposed below the locking seat body 2230 and is hollow. The lower axial end of the rod 222 is located in the connecting post 2234, and the connecting pin 227 passes through the connecting post 2234 to connect the lower axial end of the rod 222 to the connecting post 2234, so that when the rod 222 is pushed by the driving member 221, it can drive the locking seat 223 to move downward. In this embodiment, the locking seat 223 can move vertically relative to the first base 23 and the second base 26.

[0038] The first base 23 includes a first base body 231 and a first inclined surface 232 disposed on the lower side of the first base body 231. The first inclined surface 232 tapers downward from the lower side of the first base body 231. The position of the first inclined surface 232 corresponds to the through hole 2233 of the locking seat 223. This embodiment has three first inclined surfaces 232. The locking member 24 located in the through hole 2233 has a second inclined surface 241 that mates with the first inclined surface 232. The second inclined surface 241 fits against the first inclined surface 232. When the pipe assembly 3 is in the locked state, the three first inclined surfaces 232 are respectively opposite to the three through holes 2233. At this time, the locking member 24 located in the through hole 2233 extends out of the through hole 2233 and is pressed against the first inclined surface 232. That is, the locking member 24 is pushed outward along the radial direction of the locking seat 223 by the first inclined surface 232 and pressed against the second branch pipe 32, thereby locking the first branch pipe 31 and the second branch pipe 32. When the pipe assembly is in the unlocked state, the locking member 24 moves downward relative to the first base 23, that is, the through hole 2233 moves downward, driving the locking member 24 to move downward. The second inclined surface 241 of the locking member 24 moves downward along the first inclined surface 232. As the second inclined surface 241 moves downward, the locking member 24 moves inward along the radial direction of the locking seat 223, releasing the contact with the second branch pipe 32, thereby unlocking the first branch pipe 31 and the second branch pipe 32. Preferably, the locking member 24 has a friction plate 242 on the side opposite to the second inclined surface 241, i.e., the side facing the second branch pipe 32, to increase the friction between it and the second branch pipe 32. Furthermore, the first base body 231 has a first mounting hole 233 for connecting to the second base 26. Preferably, the first mounting hole 233 is located between two adjacent first inclined surfaces 232. A fixing pin 234 passes through the first mounting hole 233 to mount the second base 26 onto the first base 23.

[0039] The second base 26 includes a second base body 261, a connecting rod 263 disposed on the upper side of the second base body 261, and a recess 262 disposed on the lower side of the second base body 261. In this embodiment, the second base body 261 is generally columnar. An upward-opening receiving hole 264 is formed inside the second base body 261. A locking seat 223 is partially received in the receiving hole 264. Preferably, the connecting post 2234 of the locking seat 223 is at least partially located in the receiving hole 264. A second elastic member 25 is disposed in the receiving hole 264 and abuts against the connecting post 2234 and the receiving hole 264. Preferably, the second elastic member 25 is a spring. The connecting rod 263 extends upward from the upper side of the second base body 261, and its end away from the second base body 261 has a second mounting hole 265. A retaining pin 234 passes through the second mounting hole 265 and the first mounting hole 233 to mount the second base 26 onto the first base 23. The connecting rod 263 engages in the slot 2232 of the locking seat 223, thereby preventing rotation of the locking seat 223. A recess 262 is provided on the side of the second base body 261, recessed from the side of the second base body 261. One end of the linkage assembly 4 is mounted on this recess 262.

[0040] In this embodiment, the linkage assembly 4 includes a fixed base 41 disposed at the lower end of the second branch pipe 32, a rotating wheel 42 installed in the fixed base 41, and a linkage member 43 passing around the rotating wheel 42. The fixed base 41 has a receiving groove 411, in which the rotating wheel 42 is installed. Preferably, the receiving groove 411 is approximately U-shaped. The rotating wheel 42 is disposed at the bottom of the U-shaped receiving groove 411. The linkage member 43 enters from one end of the U-shaped receiving groove 411, passes around the rotating wheel 42, and then exits from the other end of the U-shaped receiving groove 411. In this embodiment, the linkage member 43 is plate-shaped. One end of the linkage member 43 is fixed to the outside of the recess 262, and the other end is fixed to the second connecting sleeve 35. Specifically, the linkage 43 enters one end of the receiving groove 411 from the recess 262 along the inner side of the second branch pipe 32, and exits from the gap between the rotating wheel 42 and the receiving groove 411, extending from the other end of the receiving groove 411 and extending along the outer side of the second branch pipe 32 to the second connecting sleeve 35.

[0041] Preferably, the first connecting sleeve 34 and the second connecting sleeve 35 have the same structure. In this embodiment, the second connecting sleeve 35 is used as an example for explanation. (See also...) Figure 2 , Figures 10 to 12The second connecting sleeve 35 includes a sleeve 36 mounted on the third branch pipe 33, a baffle 39 mounted on the sleeve 36, and at least one wheel assembly 38 disposed within the sleeve 36, wherein the at least one wheel assembly 38 is pressed against the second branch pipe 32 sleeved within the third branch pipe 33 by a wedge 37. In this embodiment, the sleeve 36 is inserted into the top end of the third branch pipe 33, and the second branch pipe 32 passes through the sleeve 36 and is sleeved within the third branch pipe 33. The sleeve 36 is generally hollow cylindrical. The inner side of the sleeve 36 is provided with at least one groove 361 recessed radially outward. The groove 361 opens toward the baffle 39. The at least one wheel assembly 38 is received in the at least one groove 361, and the wedge 37 is clamped between the at least one wheel assembly 38 and the at least one groove 361. The side of the wedge 37 facing the at least one groove 361 is configured as an inclined surface. The surface of the at least one groove 361 abutting against the wedge 37 is configured as a third inclined surface 611 that mates with the inclined surface of the wedge 37. Preferably, the area below the third inclined surface 611 is a flat surface 612. The wedge block 37 cooperates with the third inclined surface 611 to press at least one wheel set 38 against the second branch pipe 32, compensating for any misalignment or installation tolerance issues between the second branch pipe 32 and the inner side of the second connecting sleeve 35. Simultaneously, the configuration of at least one wheel set 38 ensures smooth movement of the second branch pipe 32 relative to the second connecting sleeve 35. In this embodiment, the at least one wheel set 38 includes three wheel sets. The three wheel sets are arranged at equal intervals along the circumference of the sleeve 36. Each wheel set 38 includes a wheel frame 381, two connecting shafts 382 respectively mounted at both ends of the wheel frame 381, and a plurality of rollers 383 mounted between the wheel frames 381. Preferably, the plurality of rollers 383 protrude from the two connecting shafts 382 along the radial direction of the sleeve 36. In this embodiment, the plurality of rollers 383 includes three rollers arranged side-by-side between the two connecting shafts 382.

[0042] Also refer to Figures 6 to 9 When using the telescopic bracket 200 of the present invention, the user presses the driving member 221 (preferably, the horizontal part of the driving member 221 is in a horizontal state when it is in the unlocked position), the lower side of the driving member 221 moves downward, compressing the first elastic member 224, and at the same time pushing the rod 222 to move downward. The rod 222 drives the locking seat 223 to move downward, engaging the through hole 2233 of the locking seat 223 (e.g., Figure 4As shown, the locking member 24 moves downward, and due to the cooperation between the first inclined surface 232 of the first base 23 and the second inclined surface 241 of the locking block 24, the locking member 24 has space to move inward, thereby disengaging from the inside of the second branch pipe 32 and unlocking the connection between the first branch pipe 31 and the second branch pipe 32, allowing the user to move relative to each branch pipe. At this time, the linkage member 43 of the linkage assembly 4 is fixed at one end of the recess 262 and can move with the movement of the first branch pipe 31 relative to the second branch pipe 32. When the position of the linkage member 43 relative to the second branch pipe 32 changes with the movement of the first branch pipe 31, the length of the linkage member 43 between the recess 262 and the receiving groove 411 changes, causing the length of the linkage member 43 between the second connecting sleeve 35 and the receiving groove 411 to change, thereby driving relative movement between the second branch pipe 32 and the third branch pipe 33, thus realizing the linkage between the first branch pipe 31, the second branch pipe 32 and the third branch pipe 33.

[0043] When the height of the tube assembly 3 reaches the required height, the drive member 221 is released. Under the action of the first elastic member 224, the drive member 221 deflects upward. At this time, under the downward force applied by the photographic equipment on the gimbal 11 mounted on the support assembly 1, the first inclined surface 232 of the first base 23 interacts with the second inclined surface 241 of the locking member 24, and moves the locking member 24 outward. The locking member 24 fits against the inner side of the second branch tube 32 to achieve fixation. More preferably, under the action of the second elastic member 25 disposed between the locking seat 223 and the second base 26, the locking seat 223 is pressed upward by the second elastic member 25. At the same time, under the action of the first inclined surface 232 of the first base 23 and the second inclined surface 241 of the locking member 24, the self-locking state of the tube assembly 3 can be effectively ensured without adding any external locking structure.

[0044] Furthermore, the present invention also provides a photographic equipment component. For example... Figure 13 As shown, the photographic equipment assembly 900 of the present invention includes the telescopic bracket 200 described above and photographic equipment (such as a monitor, camera, camcorder, etc.) mounted on the telescopic bracket 200.

[0045] The telescopic bracket for photographic equipment provided by this invention can easily and quickly lock and release the connection between the branch tubes of the tube assembly, and has a reliable locking effect, thus improving the safety of the connection.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes and modifications made in accordance with the content of the present invention should fall within the technical scope of the present invention.
