Description

Technical Field

[0001] The present invention relates to photography technology, and more particularly to an outdoor photography bracket. Background Art

[0002] With the continuous improvement of the quality of life, the use of cameras is becoming more and more popular. Especially when traveling, tourists who like to take photos will carry cameras, photographic tripods and other photographic equipment to record the beautiful scenery during the journey.

[0003] In outdoor shooting, both amateur and professional users generally cannot do without the assistance of a tripod. The main function of a tripod is to stabilize the shooting equipment in order to achieve specific shooting effects, such as star trail shooting, flowing water shooting, night scene shooting, etc. The role of the tripod cannot be underestimated during the shooting process.

[0004] The existing tripod photography bracket has a complex structure, occupies a large space, is difficult to carry, is inconvenient to transport, and is also very troublesome to set up.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide an outdoor photography stand that is easy to carry.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: an outdoor photography stand, comprising a base column, a telescopic column detachably connected to the top of the base column, a pan head rotatably connected to the top of the telescopic column, three mounting grooves are provided on the outer peripheral wall of the bottom of the base column along the length direction of the base column, the three mounting grooves are evenly spaced along the circumferential direction of the outer peripheral wall of the base column, a support foot is slidably connected in the mounting groove along the length direction, the outer diameter of the support foot is the same as the radius of the base column, sliding grooves are provided on both sides of the support foot along the length direction, and the bottom of the base column corresponds to the support foot. A sliding cavity is provided on the outer circumferential wall between adjacent mounting grooves, and through holes connected to the mounting groove are provided on the inner walls on both sides of the sliding cavity. Two plug blocks are slidably connected in the sliding cavity along the circumferential direction, and a sliding pin for inserting into the through hole is provided at the opposite ends of the two plug blocks. The sliding pin is cylindrical and bent along the circumferential direction of the bottom column. A first plug hole for inserting the sliding pin is provided at the bottom end of the bottom wall in the sliding groove, and a second plug hole for inserting the sliding pin is provided at the top end of the bottom wall in the sliding groove, and an inclined surface for contacting the bottom wall in the mounting groove is provided on the top of the support foot.

[0008] When the support leg is in the state of being moved along the longitudinal axis of the support frame, the sliding pin on one side of the sliding pin is pulled out from the first insertion hole in the sliding groove on both sides of the support leg and enters the sliding groove, so that the support leg can be pulled out downward from the installation groove and the sliding pin can slide in the sliding groove. The support leg is limited by the sliding pin, so that the support leg is not easy to shake during the sliding process and is more stable and smooth. When the sliding pin moves to the connecting part of the sliding groove and the second insertion hole, the insert block is pushed in the opposite direction so that the sliding pin is stuck in the second insertion hole. At this time, the support leg cannot slide due to the limitation of the sliding pin on the support leg, and can only rotate with the sliding pin as the center of the circle. By turning over the support leg and making the inclined surface of the top of the support leg contact with the bottom wall in the installation groove, the support leg can be The bottom column is turned into a tripod, and then the camera is mounted on the pan head of the telescopic column, so that stable shooting can be performed. When disassembly and transportation are required, the camera is first removed from the pan head, and the telescopic column is removed from the bottom column, thereby reducing the overall length of the photographic bracket and facilitating carrying. Subsequently, the supporting leg only needs to be flipped over in the opposite direction so that the inner side surface of the supporting leg and the bottom wall in the mounting groove are on the same plane, and the plug block is pushed so that the sliding pin is pulled out of the second insertion hole and enters the sliding groove, and the supporting leg can be pushed upward so that the supporting leg gradually slides upward in the mounting groove and finally fits with the mounting groove, thereby turning the bottom column into a columnar body with a smooth surface, and then the plug block is pushed so that the plug block is stuck in the first insertion hole, so that the supporting leg cannot slide, and the bottom column can be easily put into a bag for carrying and transportation, which greatly reduces the space occupied by the bracket, is convenient to carry, and saves time and effort in construction.

[0009] The present invention is further configured as follows: sliding blocks are arranged on both sides of the insert block, and sliding grooves for sliding the sliding blocks are opened along the length direction on the top wall and the bottom wall of the sliding cavity.

[0010] By adopting the above technical solution, since sliding blocks are provided on both sides of the plug block, the sliding blocks slide in the sliding grooves on both sides of the sliding cavity, thereby realizing the sliding connection of the plug block in the sliding block, and the sliding grooves limit the sliding blocks, making it less likely for the plug block to shake during the sliding process, and making it more stable and smooth.

[0011] The present invention is further configured as follows: tension springs are fixedly connected to both sides of the sliding groove, and one end of the tension spring away from the connection with the sliding groove is fixedly connected to the sliding block.

[0012] By adopting the above technical scheme, since a tension spring is fixedly connected between the sliding groove and the sliding block, when the support leg needs to slide, the plug blocks are pulled in directions opposite to each other, so that the tension spring is stretched and generates elastic force to restore its original state. After the sliding pin is separated from the first plug hole and enters the sliding groove, the sliding pin is limited by the bottom wall of the sliding groove, so that the tension spring always remains in a stretched state. When the sliding pin moves to the connecting part of the sliding groove and the second plug hole, the sliding pin is no longer limited, so the tension spring restores its original state. Under the elastic force of the tension spring, the sliding pin is automatically stuck in the second plug hole and is not easy to be separated from the second plug hole. Similarly, during the transportation process, the sliding pin is not easy to be separated from the first plug hole, thereby making the connection of the support leg more stable.

[0013] The present invention is further configured as follows: a gripping block is provided on a surface of the inserting block away from the bottom wall of the sliding cavity.

[0014] By adopting the above technical solution, since a holding block is provided on the top surface of the plug block, the holding block provides a force point for pushing and pulling the plug block, so that people can drive the plug block to slide by pushing and pulling the holding block, and the operation is more convenient and labor-saving.

[0015] The present invention is further configured as follows: a movable component is arranged on the inner side of the bottom of the support leg, the movable component includes a connecting block, the bottom of the connecting block is rotatably connected to a pulley, and a connecting groove for accommodating the connecting block and the pulley is opened at the bottom end of the bottom wall of the installation groove.

[0016] By adopting the above technical solution, since a movable component is provided at the bottom of the supporting leg, and the movable component includes a connecting block and a pulley rotatably connected to the bottom of the connecting block, after the supporting leg is unfolded, the pulley can rotate 360° against the ground, thereby facilitating the photographic bracket to slide in all directions and facilitating multi-directional shooting of objects.

[0017] The present invention is further configured such that: one end of the sliding pin away from the insert block is rotatably connected to a ball, and the radius of the sliding pin is smaller than the radius of the ball.

[0018] By adopting the above technical solution, since the end of the sliding pin away from the plug block is rotatably connected to a ball with a radius larger than the sliding pin, when the sliding pin is inserted into the second socket, the ball is also inserted into the second socket and contacts the inner wall of the second socket, so that the ball can rotate in the second socket, thereby realizing the flipping operation of the support leg, and the flipping is smoother.

[0019] The present invention is further configured as follows: the telescopic column includes a tubular column body, a sleeve is slidably connected to the inside of the column body along the length direction, a rotary block is rotatably connected to the bottom of the column body, a fixed block is rotatably connected to the bottom of the rotary block, a screw is fixedly connected to the top of the rotary block, the sleeve is threadedly connected to the screw, a connecting shaft is provided at the top of the sleeve, and the pan head is rotatably connected to the top of the connecting shaft.

[0020] By adopting the above technical solution, since the telescopic column includes a column body, and a sleeve is slidably connected inside the column body, after the bottom column is unfolded, the telescopic column is installed on the top of the bottom column, and then the rotary block located between the fixed block and the column body is rotated, so that the screw on the top of the rotary block rotates accordingly. Since the sleeve is threadedly connected to the screw and the sleeve can only slide along the length direction inside the column body, as the screw rotates, the sleeve can only reciprocate along the length direction of the screw, thereby driving the connecting shaft at the top of the sleeve and the gimbal to extend upward out of the top of the column, thereby completing the height adjustment operation of the bracket, and the operation is convenient. The sleeve is limited by the threaded structure on the screw, so that the sleeve is not easy to slide when the knob is not turned, so that the height of the gimbal is not easy to change after it is determined, and the shooting is more stable.

[0021] The present invention is further configured as follows: limiting blocks are arranged on the outer circumferential walls on both sides of the sleeve, and limiting grooves for the limiting blocks to be inserted are opened along the length direction on the inner circumferential walls on both sides of the column.

[0022] By adopting the above technical solution, since limiting blocks are provided on the outer circumferential walls on both sides of the sleeve, the limiting blocks slide in the limiting grooves, thereby realizing the sliding connection of the sleeve inside the main body, and the limiting grooves limit the limiting blocks, so that the sleeve can only slide and cannot rotate with the screw, so that the pan head can stably rise or fall when the screw rotates, and the height adjustment operation is more stable.

[0023] The present invention is further configured as follows: an embedding block is arranged at the bottom end of the fixing block, a embedding groove for the embedding block to be inserted is provided at the top end of the bottom column, an external thread structure is arranged on the outer peripheral wall of the embedding block, and an internal thread structure matching the external thread structure is arranged on the inner peripheral wall of the embedding groove.

[0024] By adopting the above technical solution, since an embedding block is provided at the bottom end of the fixed block and an embedding groove is provided at the top end of the bottom column, when installing the telescopic column, the embedding block is aligned with the embedding groove and inserted, and the fixed block is rotated so that the external thread structure on the embedding block is engaged with the internal thread structure in the embedding groove, so that the fixed block and the bottom column are threadedly connected, realizing a detachable connection between the telescopic column and the bottom column, and the threaded connection has the characteristics of easy connection operation and stable connection, so that the connection of the telescopic column is convenient, fast and stable.

[0025] The present invention is further configured as follows: blocks are provided on both sides of the inclined surface, and slots for the blocks to be inserted are provided on both sides of the inner bottom wall at the bottom end of the installation groove.

[0026] By adopting the above technical solution, since blocks are provided on both sides of the inclined surface, a slot is opened on the inner wall of the bottom end of the installation groove. After the support leg is unfolded and flipped, the block is inserted into the slot. The block is limited by the slot, so that the block is not easy to fall out of the slot, so that the installation of the support leg is stable after it is unfolded and it is not easy to rotate in the opposite direction.

[0027] In summary, the present invention has the following beneficial effects: by setting the supporting legs, when the photographic stand needs to be carried, the supporting legs are pushed upward so that the supporting legs gradually slide upward in the mounting groove and finally fit into the mounting groove, thereby turning the bottom column into a columnar body with a smooth surface, and then pushing the plug block so that the plug block is inserted into the first plug hole, so that the supporting legs cannot slide, and the bottom column can be easily put into a bag for carrying and transportation, which greatly reduces the space occupied by the stand, is convenient to carry, and saves time and effort to build.

[0040] When the support leg 4 is in the state of being connected with the second support hole 10, the support leg 4 can be easily moved by the sliding pin 8. After the camera is mounted on the camera head 2, the camera can be stably taken out of the camera stand. When the camera needs to be disassembled for transportation, the camera can be first removed from the camera head 2 and the telescopic column can be removed from the camera head 1, thereby reducing the overall length of the camera stand and facilitating carrying. Subsequently, the support leg 4 can be reversely flipped so that the inner side surface of the support leg 4 and the inner bottom wall of the mounting groove 3 are in the same plane, and the insert block 7 is pushed so that the sliding pin 8 is pulled out of the second insertion hole 10 and enters the slide groove 5, and the support leg 4 can be pushed upward so that the support leg 4 gradually slides upward in the mounting groove 3 and finally fits with the mounting groove 3, thereby turning the camera head 1 into a columnar body with a smooth surface, and then pushing the insert block 7 so that the insert block 7 is stuck in the first insertion hole 9 so that the support leg 4 cannot slide, and the camera head 4 can be easily put into the bag for carrying and transportation, which greatly reduces the space occupied by the stand, is convenient to carry, and saves time and effort in construction.

[0041] Since sliding blocks 12 are provided on both sides of the plug block 7, the sliding blocks 12 slide in the sliding grooves 13 on both sides of the sliding cavity, thereby realizing the sliding connection of the plug block 7 in the sliding block 12, and the sliding grooves 13 limit the sliding block 12, so that the plug block 7 is not easy to shake during the sliding process, and is more stable and smooth.

[0042] Since a tension spring 14 is fixedly connected between the sliding groove 13 and the sliding block 12, when the sliding support leg 4 needs to be slid, the plug block 7 is pulled in the opposite directions of the two plug blocks 7, so that the tension spring 14 is stretched and generates an elastic force to restore its original state. After the sliding pin 8 disengages from the first insertion hole 9 and enters the sliding groove 5, the sliding pin 8 is limited by the inner bottom wall of the sliding groove 5, so that the tension spring 14 always remains in a stretched state. When the sliding pin 8 moves to the connecting part of the sliding groove 5 and the second insertion hole 10, the sliding pin 8 is no longer limited, so that the tension spring 14 restores its original state. Under the elastic force of the tension spring 14, the sliding pin 8 is automatically stuck in the second insertion hole 10 and is not easy to be separated from the second insertion hole 10. Similarly, during the transportation process, the sliding pin 8 is not easy to be separated from the first insertion hole 9, thereby making the connection of the support leg 4 more stable.

[0043] Since a gripping block 15 is disposed on the top surface of the inserting block 7, the gripping block 15 provides a force point for pushing and pulling the inserting block 7, so that people can push and pull the gripping block 15 to drive the inserting block 7 to slide, and the operation is more convenient and labor-saving.

[0044] Since a moving assembly is provided at the bottom of the support leg 4, and the moving assembly includes a connecting block 16 and a pulley 17 rotatably connected to the bottom of the connecting block 16, after the support leg 4 is unfolded, the pulley 17 can rotate 360° against the ground, thereby facilitating the photography bracket to slide in all directions and facilitating multi-directional shooting of the object.

[0045] Since the end of the sliding pin 8 away from the plug block 7 is rotatably connected to the ball 19 with a radius larger than the sliding pin 8, when the sliding pin 8 is inserted into the second socket 10, the ball 19 is also inserted into the second socket 10 and contacts the inner wall of the second socket 10, so that the ball 19 can rotate in the second socket 10, thereby realizing the flipping operation of the support leg 4, and the flipping is smoother.

[0046] Since the telescopic column includes a column body 20, and a sleeve 21 is slidably connected inside the column body 20, after the base column 1 is unfolded, the telescopic column is installed on the top of the base column 1, and then the rotary block 22 located between the fixed block 23 and the column body 20 is rotated, so that the screw 24 on the top of the rotary block 22 rotates accordingly. Since the sleeve 21 is threadedly connected to the screw 24 and the sleeve 21 can only slide along the length direction inside the column body 20, as the screw 24 rotates, the sleeve 21 can only reciprocate along the length direction of the screw 24, thereby driving the connecting shaft 25 at the top of the sleeve 21 and the pan-tilt head 2 to extend upward from the top of the column 20, thus completing the height adjustment operation of the bracket, and the operation is convenient. The sleeve 21 is limited by the threaded structure on the screw 24, so that the sleeve 21 is not easy to slide when the knob is not turned, so that the height of the pan-tilt head 2 is not easy to change after it is determined, and the shooting is more stable.

[0047] Since limit blocks 26 are provided on the outer walls on both sides of the sleeve 21, the limit blocks 26 slide in the limit grooves 27, thereby realizing the sliding connection of the sleeve 21 inside the main body, and the limit blocks 26 are limited by the limit grooves 27, so that the sleeve 21 can only slide and cannot rotate with the screw 24, so that the pan head 2 can stably rise or fall when the screw 24 rotates, and the operation of adjusting the height is more stable.

[0048] Since an embedding block 28 is provided at the bottom end of the fixing block 23 and an embedding groove 29 is provided at the top end of the bottom column 1, when installing the telescopic column, the embedding block 28 is aligned with the embedding groove 29 and inserted, and the fixing block 23 is rotated so that the external thread structure on the embedding block 28 is engaged with the internal thread structure in the embedding groove 29, so that the fixing block 23 and the bottom column 1 are threadedly connected, realizing a detachable connection between the telescopic column and the bottom column 1, and the threaded connection has the characteristics of convenient connection operation and stable connection, so that the connection of the telescopic column is convenient, fast and stable.

[0049] Since blocks 30 are provided on both sides of the inclined surface 11 and a slot 31 is provided on the inner wall at the bottom end of the installation slot 3, after the support leg 4 is unfolded and turned over, the block 30 is inserted into the slot 31. The block 30 is limited by the slot 31, so that the block 30 is not easy to be separated from the slot 31, so that the support leg 4 is stably installed after being unfolded and is not easy to rotate in the opposite direction.

[0050] Working principle:

[0051] In actual use, first hold the holding block 15 on the plug block 7 with your hand, and slide the two plug blocks 7 in the sliding cavity in opposite directions, driving the sliding block 12 to slide in the sliding groove 13, so that the tension spring 14 is stretched by the tension force and generates an elastic force to restore the original state. After the ball 19 at one end of the sliding pin 8 is pulled out of the first insertion hole 9 and enters the sliding groove 5, the support leg 4 is pulled downward from the installation groove 3 and the hand holding the holding block 15 is released, so that the ball 19 can roll in the sliding groove 5, and the sliding pin 8 is limited by the bottom wall of the sliding groove 5, so that the tension spring 14 is always kept in a stretched state. After the mounting groove 3 is pulled out in the above manner, the support leg 4 is continued to be pulled downward until the ball 19 moves to the connection point between the slide groove 5 and the second insertion hole 10. Since the ball 19 is no longer limited by the inner wall of the slide groove 5, the tension spring 14 returns to its original state. Under the elastic force of the tension spring 14, the ball 19 is automatically inserted into the second insertion hole 10, and the support leg 4 can rotate about the center of the ball 19. By turning over the support leg 4 and making the inclined surface 11 at the top of the support leg 4 contact with the inner bottom wall of the mounting groove 3, and making the block 30 inserted into the slot 31, the base column 1 can be turned into a tripod, and the bottom of the support leg 4 is moved to the bottom of the support leg 4. The arrangement of the movable assembly enables the pulley 17 to rotate 360° against the ground after the support leg 4 is unfolded, so that the photographic support can slide in all directions. After determining the photographic position, the embedded block 28 on the fixed block 23 at the bottom of the column 20 is aligned with the embedded groove 29 at the top of the bottom column 1 and inserted, and then the fixed block 23 is rotated so that the external thread structure on the embedded block 28 is engaged with the internal thread structure in the embedded groove 29, so that the fixed block 23 is threadedly connected with the bottom column 1, so that the telescopic column can be conveniently installed on the bottom column 1 to form a complete support. When it is necessary to adjust the photographic height, the position is rotated. The rotary block 22 between the fixed block 23 and the column 20 causes the screw 24 at the top of the rotary block 22 to rotate accordingly. Since the sleeve 21 is threadedly connected to the screw 24 and the limit blocks 26 on both sides of the sleeve 21 are limited by the limit grooves 27 inside the main body, the sleeve 21 can only slide along the length direction inside the column 20. As the screw 24 rotates, the sleeve 21 can only move axially along the length direction of the screw 24, thereby driving the connecting shaft 25 at the top of the sleeve 21 and the pan-tilt head 2 to extend upward from the top of the column 20, so that the height adjustment operation of the photographic bracket can be completed, which is more convenient.

[0052] When it is necessary to disassemble and transport, the camera is first removed from the pan / tilt 2, and the fixing block 23 is rotated in the opposite direction to remove the telescopic column from the bottom column 1, thereby reducing the overall length of the photographic bracket and facilitating carrying. Subsequently, the supporting leg 4 is flipped in the opposite direction to disengage the clamping block 30 from the clamping slot 31 and to make the inner side surface of the supporting leg 4 and the inner bottom wall of the mounting slot 3 be in the same plane, and then the two inserting blocks 7 are pushed in opposite directions to pull the ball 19 out of the second insertion hole 10 and enter the sliding groove 5, and the tension spring 14 is stretched and generates elastic force, and at this time the supporting leg 4 can be pushed upward to make the supporting leg 4 gradually slide upward in the mounting slot 3 and finally fit with the mounting slot 3, thereby making the bottom column 1 become a columnar body with a smooth surface, and the ball 19 is clamped into the first insertion hole 9 under the action of the elastic force of the tension spring 14, so that the supporting leg 4 cannot slide, thus completing the folding operation of the bottom column 1.

[0053] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
