Description

Technical Field

[0001] This invention relates to a camera stand with rapidly adjustable height. Background Technology

[0002] Existing technology, such as Chinese invention patent application document, publication number CN115750552A, discloses a telescopic outrigger locking device, including: a fixed leg; a first movable leg, slidably disposed on the fixed leg to telescopically move relative to the fixed leg; a first locking structure, disposed between the first movable leg and the fixed leg, capable of locking or unlocking the first movable leg to the fixed leg; a second movable leg, slidably disposed on the first movable leg to telescopically move relative to the first movable leg; a second locking structure, disposed between the second movable leg and the first movable leg, capable of locking or unlocking the second movable leg to the first movable leg; and a linkage mechanism, disposed between the second locking structure and the first locking structure, capable of simultaneously locking or unlocking the second locking structure and the first locking structure. This avoids operating locking mechanisms in different positions, facilitating the user's telescopic outrigger locking device and improving ease of use.

[0003] Based on the above, in the existing technology, the fixed leg, the first movable leg, and the second movable leg are all arranged in parallel. This structural arrangement makes the overall lateral dimension of the product too large, which is not conducive to carrying and storage.

[0004] Meanwhile, in the existing technology, during locking, the entire assembly consisting of the buckle, the first shaft, and the connecting rod shifts to press the first locking member against the side wall of the fixed leg, thereby fixing the first movable leg to the fixed leg. Additionally, by using a pushing block to act on the first driving block, the linkage rod moves upward, and the second driving block located at the lower end of the linkage rod acts on the second locking member to press against the side wall of the first movable leg. In this locking structure, both the second and first movable legs are fixed by pressing the locking member against the side wall of the leg. This unilateral pressing locking method is prone to damaging the surface of the leg and is susceptible to loosening or denting due to uneven force. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a photographic bracket that adopts a sleeve-type assembly structure, which can reduce the width of the product, making it easier to carry and store, and the sleeve-type locking structure can avoid wear or loosening caused by unilateral force.

[0006] A camera stand designed for this purpose with quick height adjustment includes legs, each leg including a connecting seat. A fixed tube is fixedly mounted on the connecting seat. A first locking seat is fixedly mounted on the rear end of the fixed tube. A first mounting cavity is provided in the first locking seat. A first movable tube that can move back and forth relative to the fixed tube is inserted into the fixed tube. The rear end of the first movable tube extends rearward through the first mounting cavity. A locking component is provided in the first mounting cavity for fitting onto the first movable tube and locking it to the first locking seat. A transmission component is installed on the first locking seat for driving the locking component to unlock or lock. The first locking seat is also provided with a drive component for driving the transmission component to operate.

[0007] Compared with existing technologies, this invention achieves a sleeve-type assembly structure by inserting a first movable tube that can move back and forth relative to the fixed tube, thereby reducing product size and facilitating carrying and storage. Simultaneously, a locking component is provided within the first mounting cavity for fitting onto the first movable tube and locking it to the first locking seat. This sleeve-type locking structure avoids wear or loosening caused by unilateral force. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See Figures 1-10 A camera stand with quick height adjustment includes a leg 10, the leg 10 including a connecting seat 100, a fixing tube 110 fixedly mounted on the connecting seat 100, a first locking seat 120 fixedly mounted at the rear end of the fixing tube 110, a first mounting cavity 125 provided in the first locking seat 120, a first movable tube 130 inserted into the fixing tube 110 and movable relative to the fixing tube 110, the rear end of the first movable tube 130 extending rearward through the first mounting cavity 125, a locking component 20 provided in the first mounting cavity 125 for fitting onto the first movable tube 130 and locking it to the first locking seat 120, a transmission component 30 mounted on the first locking seat 120 for driving the locking component 20 to unlock or lock, and a drive component 50 for driving the transmission component 30 to operate.

[0020] Based on the above, by inserting a first movable tube that can move back and forth relative to the fixed tube, this structure achieves a sleeve-type assembly structure, which can reduce the width of the product and facilitates carrying and storage. At the same time, a locking component is provided in the first mounting cavity for fitting onto the first movable tube and locking it to the first locking seat. The sleeve-type locking structure can avoid the problems of wear or loosening caused by unilateral force.

[0021] When it is necessary to adjust the position of the first moving pipe 130 relative to the fixed pipe 110, the first moving pipe 130 can be pulled to adjust its position relative to the fixed pipe 110 only after the drive component 50 drives the transmission component 30 to unlock the locking component 20.

[0022] See Figures 3 to 7 The first mounting cavity 125 includes, from front to back, a connecting hole 121, a conical locking hole 122, and a moving groove 123. The rear end of the fixed tube 110 is fixedly connected to the connecting hole 121. The locking assembly 20 includes a moving part 210 that is movably disposed in the moving groove 123. The moving part 210 is provided with a conical locking sleeve 220 that is sleeved on the first moving tube 130 and can be inserted into the conical locking hole 122 to clamp and lock the first moving tube 130. The conical locking sleeve 220 has multiple deformation grooves 221. The transmission assembly 30 is used to drive the moving part 210 to move back and forth relative to the moving groove 123.

[0023] The fixed pipe fitting 110 is threaded into the connection hole 121.

[0024] In the locked state, the conical locking sleeve 220 is inserted into the conical locking hole 122. The conical locking hole 122 can cause the conical locking sleeve 220 to deform and clamp the first moving tube 130, so as to achieve the first moving tube 130, the conical locking sleeve 220 and the first locking seat 120 being locked to each other.

[0025] During unlocking, the transmission assembly 30 can drive the moving part 210 to move relative to the first locking seat 120, so that the conical locking sleeve 220 disengages from the conical locking hole 122, thereby separating the conical locking sleeve 220 from the first moving tube 130 and achieving unlocking.

[0026] See Figures 4 to 8 The transmission assembly 30 includes a rotating member 310 rotatably disposed within the first mounting cavity 125. A driving helical tooth 312 is provided at one end of the rotating member 310 near the moving member 210. A driven helical tooth 212 that meshes with the driving helical tooth 312 is provided on the moving member 210. The driving assembly 50 is used to drive the moving member 210 to rotate relative to the first mounting cavity 125. An elastic member 230 is provided in the first mounting cavity 125 to apply a thrust to the moving member 210 so that the conical locking sleeve 220 is kept inserted into the conical locking hole 122.

[0027] The elastic force applied by the elastic element 230 can keep the conical locking sleeve 220 within the conical locking hole 122, thereby clamping and locking the first moving tube 130. When unlocking is required, the rotating element 310 is driven to rotate, causing the driving helical tooth 312 to drive the driven helical tooth 212 to move the moving element 210 relative to the first mounting base 120, so that the conical locking sleeve 220 disengages from the conical locking hole 122, thereby separating the conical locking sleeve 220 from the first moving tube 130 and unlocking the tube.

[0028] See Figure 4 The drive assembly 50 includes a drive member 510, a transmission rod 520 is provided on the drive member 510, the transmission rod 520 is hinged to the first locking seat 120, the rotating member 310 is provided with a driven rod 320, the driven rod 320 is provided with a sliding groove 321, and the transmission rod 520 is provided with a linkage pin 530 that is movably inserted into the sliding groove 321.

[0029] When unlocking is required, the drive member 510 is moved to rotate around the hinge axis of the transmission rod 520. During rotation, the drive member 510 is driven to rotate by the transmission rod 520 through the linkage pin 530. This drives the driven helical gear 212 to move the moving member 210 relative to the first mounting base 120, so that the conical locking sleeve 220 disengages from the conical locking hole 122 and separates from the first moving tube 130, thereby unlocking.

[0030] See Figure 3 and Figure 6 A torsion spring 330 is sleeved on the rotating component 310. One end of the torsion spring 330 is fixedly connected to the first locking seat 120, and the other end is fixed to the rotating component 310. The torsion spring 330 can apply a certain torque to the rotating component 310, so that the rotating component 310 is in the locked state of the tube.

[0031] See Figure 3 The first locking seat 120 has a rear end opening that communicates with the first mounting cavity 125. A cover plate 124 is installed at the rear end of the first locking seat 120, and the elastic member 230 is disposed between the cover plate 124 and the moving member 210. The cover plate 124 can be assembled using existing detachable connection structures, such as snap-fit ​​or screw connections.

[0032] Further, see Figures 1 to 9 The rear end of the first movable tube 130 is equipped with a second locking seat 140, and the second locking seat 140 is provided with a second mounting cavity 141. A second movable tube 150 that can move back and forth relative to the first movable tube 130 is inserted into the first movable tube 130. The rear end of the second movable tube 150 extends rearward through the second mounting cavity 141. A locking component 20 for fitting onto the second movable tube 150 and locking it to the second locking seat 140 is provided in the second mounting cavity 141. A transmission component 30 for driving the locking component 20 to unlock or lock is installed on the second locking seat 140. A linkage component 40 is connected to the transmission component 30 in the first locking seat 120 and the transmission component 30 in the second locking seat 140.

[0033] Specifically, the structure of the second locking seat 140 is the same as that of the first locking seat 120, the shape of the second mounting cavity 141 is the same as that of the first mounting cavity 125, and the structure of the locking component 20 and the transmission component 30 installed in the second locking seat 140 are the same as those in the first locking seat 120.

[0034] In this scheme, a first movable pipe fitting 130 is inserted into a fixed pipe fitting 110, and a second movable pipe fitting 150 is inserted into a first movable pipe fitting 130 to achieve a three-stage telescopic adjustment setting. Compared with the existing parallel pipe fitting setting, this structure has a smaller volume and can ensure the stability of the support.

[0035] The linkage component 40 is configured so that when the locking component 20 in the first locking seat 120 is unlocked, the locking component 20 in the second locking seat 140 will also be unlocked simultaneously, so that the first moving tube 130 and the second moving tube 150 will be locked or unlocked simultaneously.

[0036] Further, see Figure 1 and Figure 2 The linkage component 40 includes a linkage rod 410. The rotating parts 310 in the two transmission components 30 are both cylindrical. The linkage rod 410 is inserted into the rotating parts 310 in the two transmission components 30. The linkage rod 410 is moved back and forth with the two rotating parts 310 respectively. The front end of the linkage rod 410 is provided with a first limiting member 430, and the rear end of the linkage rod 410 is provided with a second limiting member 142.

[0037] The function of the first limiting member 430 and the second limiting member 142 is to prevent the linkage rod 410 from disengaging from the rotating member 310.

[0038] See Figure 4 The rotating member 310 is provided with a driven member 420. The inner wall of the rotating member 310 is provided with a first positioning groove 311, and the outer wall of the linkage rod 410 is provided with a second positioning groove 411. The driven member 420 is provided with a positioning block 421 that is inserted into the first positioning groove 311 and the second positioning groove 411. The positioning block 421 is respectively inserted into the first positioning groove 311 and the second positioning groove 411, which can realize that the rotating member 310, the driven member 420 and the linkage rod 410 are a linked whole. When the linkage rod 410 rotates, it will drive the driven member 420 and the rotating member 310 to rotate.

[0039] Furthermore, a first through hole 211 is provided on the movable part 210, and the linkage rod 410 is set through the first through hole 211.

[0040] Furthermore, the driven helical tooth 212 is disposed within the first through hole 211.

[0041] Specifically, the first locking seat 120 and the second locking seat 140 are provided with a second through hole 126 for the linkage rod 410 to pass through.

[0042] The second limiting member 142 is a bolt, which is inserted from the outside to the rear into the second locking seat 140 and threadedly connected to the rear end of the linkage rod 410.

[0043] See Figure 1 The second movable pipe fitting 150 is equipped with a support base 160 at its rear end, and a support leg 170 is installed on the support base 160.

[0044] See Figure 10 A stabilizing seat 80 is provided between multiple support legs 10. A telescopic rod 70 is hinged to the stabilizing seat 80, and the other end of the telescopic rod 70 is hinged to the first locking seat 120.
