Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photographic equipment, in particular to a tripod. BACKGROUND

[0002] In the process of photography or shooting, a tripod is often needed to fix the photographic equipment. However, the existing tripod is often expanded along the axial direction of the center tube by sliding the three-pronged support frame, so that the radial size of the tripod is increased synchronously during the expansion process. When the tripod is applied to some specific scenes with limited installation space (for example, the installation space is small in the middle and large at the bottom), the three-pronged support frame cannot be directly expanded during the sliding process due to the limitation of the installation space, which causes the tripod to be unable to be normally used. SUMMARY

[0003] Therefore, it is necessary to provide a tripod that can be applied to specific scenes with limited installation space.

[0004] A tripod, comprising:

[0005] a center tube, a top end of the center tube being used to install a photographic equipment; and

[0006] a three-pronged support frame, connected with the center tube and arranged near a bottom end of the center tube, the three-pronged support frame being capable of moving along the axial direction of the center tube relative to the center tube, and the three-pronged support frame being capable of being expanded during the process of continuously moving towards the bottom end of the center tube after moving along the axial direction of the center tube by a preset stroke, and the three-pronged support frame being capable of being folded during the process of moving along the axial direction of the center tube towards the top end of the center tube.

[0007] In one embodiment, the three-pronged support frame comprises a sliding seat and three support legs, the sliding seat being slidingly sleeved on the periphery of the center tube, one end of each of the support legs being rotationally connected to the sliding seat, the three support legs being arranged at intervals on the outer periphery of the sliding seat, and the support legs being capable of rotating towards the direction away from the center tube and being expanded during the process of continuously moving towards the bottom end of the center tube after the support legs follow the sliding seat to move along the axial direction of the center tube by the preset stroke, and the support legs being capable of rotating towards the direction close to the center tube and being folded during the process of moving along the axial direction of the center tube towards the top end of the center tube.

[0008] In one of the embodiments, the triangular supporting frame further comprises three first pivots, one end of each of the supporting legs is pivotally connected to the sliding seat via one of the first pivots, and each of the supporting legs is capable of rotating relative to the sliding seat about the axis of the first pivot corresponding to the supporting leg.

[0009] In one of the embodiments, the triangular supporting frame further comprises three first elastic members, each of the first elastic members is configured to provide elastic force to the corresponding supporting leg to drive the corresponding supporting leg to rotate towards the center tube, and the triangular supporting frame further comprises three first elastic members, each of the first elastic members is corresponding to one of the supporting legs.

[0010] In one of the embodiments, the tripod further comprises a sleeve, the sleeve is sleeved on the periphery of the center tube, the triangular supporting frame is capable of extending out of the sleeve through the bottom opening of the sleeve in the unfolded state, and the triangular supporting frame is capable of being retracted into the sleeve through the bottom opening of the sleeve in the folded state.

[0011] In one of the embodiments, the tripod further comprises a locking assembly, the locking assembly has a locked state and an unlocked state, the locking assembly is capable of locking the triangular supporting frame in the folded state in the sleeve when the locking assembly is in the locked state, and the locking assembly is capable of releasing the locking of the triangular supporting frame in the folded state relative to the sleeve when the locking assembly is in the unlocked state.

[0012] In one of the embodiments, the sleeve is provided with a through hole on the side wall, the locking assembly comprises a lock catch, the lock catch comprises a main body portion and a lock catch portion connected to the main body portion, the main body portion is pivotally arranged on the sleeve to switch the lock catch between the locked state and the unlocked state.

[0013] When the lock catch is in the locked state, the lock catch portion is capable of extending into the sleeve through the through hole and clamping the triangular supporting frame to hinder the movement of the triangular supporting frame relative to the center tube and the sleeve along the axis of the center tube, thereby locking the triangular supporting frame in the folded state in the sleeve.

[0014] When the lock catch is in the unlocked state, the lock catch portion is capable of extending out of the sleeve through the through hole and separating from the triangular supporting frame, thereby releasing the locking of the triangular supporting frame in the folded state.

[0015] In one of the embodiments, the locking assembly further comprises a second pivot, the main body portion is pivotally arranged on the sleeve via the second pivot, and the main body portion is capable of rotating relative to the sleeve about the axis of the second pivot.

[0016] In one embodiment, the locking assembly further includes a second elastic element, which provides elastic force to the main body to cause the main body to rotate the latching part toward the through hole, thereby causing the latching part to extend through the through hole into the sleeve and engage with the triangular support frame.

[0017] In one embodiment, the tripod further includes a third elastic element disposed within the sleeve, the third elastic element being used to drive the triangular support frame to move along the axial direction of the central tube and toward the bottom end of the central tube.

[0018] The tripod provided in this application allows the user to drive the tripod support frame along the axial direction of the central tube and towards the bottom of the central tube during use. This allows the tripod support frame to unfold as it moves a preset distance along the axial direction of the central tube towards the bottom of the central tube, thus providing support for the tripod. Compared to existing tripods where the tripod support frame slides along the axial direction of the central tube while unfolding, the tripod support frame of this application first moves a preset distance along the axial direction of the central tube towards the bottom of the central tube before automatically unfolding. Therefore, the tripod of this application... The radial dimension of the tripod only increases after the tripod support moves a preset distance along the axial direction of the central tube towards the bottom of the central tube. This allows the tripod of this application to be normally unfolded in certain scenarios where installation space is limited (such as installation spaces that are small in the middle and large at the bottom), thereby meeting the user's needs. When the tripod is not needed, the user can drive the tripod support along the axial direction of the central tube towards the top of the central tube to fold the tripod support, thereby reducing the space occupied by the tripod and making the folded tripod compact, which is convenient for users to store and carry.

Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In addition, "and / or" throughout the text includes three schemes, for example, A and / or B includes A technical scheme, B technical scheme, and A and B simultaneously meet the technical scheme; in addition, the technical schemes of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical schemes appears contradictory or cannot be realized, it should be considered that the combination of technical schemes does not exist, nor in the protection scope required by the present application.

[0032] As shown in Figure 1 and Figure 2 The present application provides a tripod 10, which comprises a center tube 100 and a triangular support frame 200, the top end of the center tube 100 is used to install a photographic equipment; the triangular support frame 200 is connected with the center tube 100 and is arranged close to the bottom end of the center tube 100, the triangular support frame 200 can move along the axial direction of the center tube 100 relative to the center tube 100, and the triangular support frame 200 can be unfolded in the process of continuing to move towards the bottom end of the center tube 100 after moving a preset stroke along the axial direction of the center tube 100 and towards the bottom end of the center tube 100, and the triangular support frame 200 can be folded in the process of moving along the axial direction of the center tube 100 and towards the top end of the center tube 100.

[0033] The tripod 10 provided by the application can be used in the following manner. When the tripod 10 is used, the user can drive the triangular support frame 200 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100, so that the triangular support frame 200 is unfolded in the process of continuing to move towards the bottom end of the central pipe 100 after moving along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset distance, thereby achieving support of the tripod 10. Compared with the existing tripod whose triangular support frame slides along the axial direction of the central pipe and is unfolded, since the triangular support frame 200 of the tripod 10 provided by the application is first moved along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset distance and then automatically unfolded, the radial dimension of the tripod 10 provided by the application will only become larger after the triangular support frame 200 moves along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset distance. Therefore, the tripod 10 provided by the application can be normally unfolded in some specific scenarios (for example, an installation space with a small middle part and a large bottom part) where the installation space is limited, thereby meeting the use requirements of the user. When the tripod 10 provided by the application is not needed to be used, the user can drive the triangular support frame 200 to move along the axial direction of the central pipe 100 and towards the top end of the central pipe 100, so that the triangular support frame 200 is folded, thereby reducing the space occupied by the tripod 10 and achieving miniaturization of the folded tripod 10, which is convenient for the user to store and carry.

[0034] As shown in Figure 2 and Figure 3 The triangular support frame 200 includes a sliding seat 210 and three support legs 220. The sliding seat 210 is slidably arranged on the periphery of the central pipe 100. One end of each of the three support legs 220 is rotatably connected to the sliding seat 210. The three support legs 220 are arranged at intervals on the outer periphery of the sliding seat 210. When the support legs 220 continue to move towards the bottom end of the central pipe 100 after moving along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset distance along with the sliding seat 210, the support legs 220 can rotate away from the central pipe 100 and be unfolded. When the support legs 220 move along the axial direction of the central pipe 100 and towards the top end of the central pipe 100 along with the sliding seat 210, the support legs 220 can rotate towards the central pipe 100 and be folded.

[0035] Specifically, when the triangular support frame 200 needs to be unfolded, it is only needed to drive the sliding seat 210 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100, when the support legs 220 follow the sliding seat 210 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset stroke and then continue to move towards the bottom end of the central pipe 100, the support legs 220 can rotate away from the central pipe 100 and achieve unfolding, at the same time, the included angle formed between the support legs 220 and the central pipe 100 gradually increases, when the included angle formed between the support legs 220 and the central pipe 100 reaches a preset angle, at this time, the triangular support frame 200 is at the maximum extent of unfolding; when the triangular support frame 200 needs to be folded, it is only needed to drive the sliding seat 210 to move along the axial direction of the central pipe 100 and towards the top end of the central pipe 100, at this time, the support legs 220 can rotate towards the central pipe 100 and achieve folding, at the same time, the included angle formed between the support legs 220 and the central pipe 100 gradually decreases, when the support legs 220 rotate to be parallel to the central pipe 100 (i.e. the included angle formed between the support legs 220 and the central pipe 100 decreases to 0 degree), at this time, the triangular support frame 200 is at the maximum extent of folding.

[0036] As shown in Figure 3 Specifically, in the present embodiment, the three support legs 220 are uniformly and spacedly arranged on the outer periphery of the sliding seat 210.

[0037] As shown in Figure 4 The triangular support frame 200 further comprises three first rotation shafts 230, one end of the support leg 220 is rotationally connected to the sliding seat 210 through the first rotation shaft 230, the support leg 220 can rotate relative to the sliding seat 210 around the axial direction of the first rotation shaft 230, and the three first rotation shafts 230 correspond to the three support legs 220 one by one.

[0038] Specifically, the outer periphery of the sliding seat 210 is spacedly provided with three first installation grooves 212, the first rotation shaft 230 is connected and arranged between the opposite two inner side walls of the first installation groove 212, the three first installation grooves 212 correspond to the three first rotation shafts 230 one by one, and one end of the support leg 220 is rotationally sleeved on the first rotation shaft 230.

[0039] The triangular support frame 200 further comprises three first elastic members 240, which are used to provide elastic force to the support legs 220 to drive the support legs 220 to rotate towards the center tube 100. The three first elastic members 240 are in one-to-one correspondence with the three support legs 220. Through the arrangement of the first elastic members 240, the first elastic members 240 can drive the support legs 220 to rotate towards the center tube 100 under the elastic force of the first elastic members 240 to achieve automatic folding of the support legs 220 in a natural state (i.e., no external force acting on the sliding seat 210). In addition, when it is necessary to switch the support legs 220 from the folded state to the unfolded state, the sliding seat 210 is driven to move along the axial direction of the center tube 100 and towards the bottom end of the center tube 100 by a predetermined stroke, and then the sliding seat 210 is continuously driven to move towards the bottom end of the center tube 100, and the sliding seat 210 overcomes the elastic force of the first elastic members 240 on the support legs 220 to drive the support legs 220 to rotate towards the center tube 100.

[0040] Specifically, the first elastic member 240 can be a torsion spring, the first elastic member 240 is sleeved on the outside of the first rotating shaft 230, one end of the first elastic member 240 abuts against the support leg 220, and the other end of the first elastic member 240 abuts against the sliding seat 210. Further, the support leg 220 is abutted against the inner side wall of the first mounting groove 212 on the side of the one end of the first rotating shaft 230, and the first elastic member 240 is located between the opposite side of the one end of the first rotating shaft 230 and the opposite inner side wall of the first mounting groove 212. Further, the first elastic member 240 is sleeved on the first rotating shaft 230, and the first elastic member 240 is sleeved on the first rotating shaft 230.

[0041] As shown in Figure 1 , Figure 2 and Figure 5 , the tripod 10 further comprises a sleeve 300, which is sleeved on the periphery of the center tube 100, and the sleeve 300 is coaxially arranged with the center tube 100. The triangular support frame 200 can be stretched out of the sleeve 300 through the bottom end opening of the sleeve 300 in the unfolded state, and the triangular support frame 200 can be retracted and stored in the sleeve 300 through the bottom end opening of the sleeve 300 in the folded state.

[0042] Specifically, when the tripod 10 needs to be used, the triangular support frame 200 in the unfolded state can be extended out of the sleeve 300 through the bottom end opening of the sleeve 300, and when the tripod 10 does not need to be used, the triangular support frame 200 in the folded state can be retracted and stored in the sleeve 300 through the bottom end opening of the sleeve 300. Compared with the conventional setting mode in which the triangular support frame is exposed when in the folded state, the sleeve 300 is arranged in the present application, so that the triangular support frame 200 in the folded state can be stored in the sleeve 300, thereby improving the appearance of the tripod 10. Meanwhile, the sleeve 300 can also play a certain protective role for the triangular support frame 200 in the folded state, avoiding damage caused by exposure to the outside during transportation and storage, and avoiding the defect that the triangular support frame in the folded state is exposed to the outside, resulting in a gap between the adjacent two support legs of the triangular support frame, which is easy to cause hand injury.

[0043] Further, when the triangular support frame 200 is in the folded state, the triangular support frame 200 can be retracted into the sleeve 300 through the bottom end opening of the sleeve 300, that is, the triangular support frame 200 in the folded state can be completely stored in the sleeve 300, thereby further improving the appearance of the tripod 10.

[0044] As shown in Figure 2 In the present embodiment, the sliding seat 210 is limited in sliding within the sleeve 300, avoiding the sliding seat 210 from being separated from the sleeve 300 through the top and bottom openings of the sleeve 300 during the axial movement along the central pipe 100. Specifically, the sliding seat 210 can abut against the inner walls of the top end and the bottom end of the sleeve 300 to limit the sliding seat 210 within the sleeve 300.

[0045] Further, when the triangular support frame 200 is in the unfolded state, the three support legs 220 of the triangular support frame 200 can be extended out of the sleeve 300 through the bottom end opening of the sleeve 300, and when the triangular support frame 200 is in the folded state, the three support legs 220 of the triangular support frame 200 can be retracted into the sleeve 300 through the bottom end opening of the sleeve 300.

[0046] As shown in Figure 1 Further, the bottom end opening of the sleeve 300 includes three through holes 310 arranged at intervals at the bottom end of the sleeve 300, and the support legs 220 can be extended out of the sleeve 300 or retracted and stored in the sleeve 300 through the holes 310, and the three through holes 310 correspond to the three support legs 220 one by one.

[0047] As shown in Figure 5 and Figure 6As shown, the tripod 10 also includes a locking assembly 400, which has a locked state and an unlocked state. When the locking assembly 400 is in the locked state, it can lock the folded tripod support 200 inside the sleeve 300 to prevent the folded tripod support 200 from being accidentally unfolded. When the locking assembly 400 is in the unlocked state, it can release the lock on the folded tripod support 200, so that the folded tripod support 200 can be unfolded and the tripod 10 can be used normally.

[0048] like Figure 7 As shown, the sleeve 300 further has a through hole 320 on its side wall, and the locking assembly 400 includes a latch 410. The latch 410 includes a main body 411 and a latch part 412 connected to the main body 411. The main body 411 is rotatably disposed on the sleeve 300 so that the latch 410 can switch between a locked state and an unlocked state.

[0049] When the latch 410 is in the locked state, the latch part 412 can extend into the sleeve 300 through the through hole 320 and engage with the triangular support frame 200, thereby preventing the triangular support frame 200 from moving relative to the center tube 100 and the sleeve 300 along the axial direction of the center tube 100, thus locking the folded triangular support frame 200 inside the sleeve 300; when the latch 410 is in the unlocked state, the latch part 412 can extend out of the sleeve 300 through the through hole 320 and separate from the triangular support frame 200, thereby releasing the lock on the folded triangular support frame 200.

[0050] Specifically, initially, the latch 410 is in a locked state. The latching part 412 of the latch 410 extends into the sleeve 300 through the through hole 320 and engages with the triangular support frame 200. The latching part 412 can prevent the triangular support frame 200 from moving relative to the center tube 100 and the sleeve 300 along the axial direction of the center tube 100, thereby locking the folded triangular support frame 200 in the sleeve 300.

[0051] When the tripod 10 needs to be used (i.e. the triangular support frame 200 needs to be switched from the folded state to the unfolded state), the main body part 411 of the lock catch 410 can be driven to rotate the lock catch part 412 away from the through hole 320, so as to switch the lock catch 410 from the locked state to the unlocked state, so that the lock catch part 412 extends out of the sleeve 300 through the through hole 320 and is separated from the triangular support frame 200, thereby releasing the locking of the triangular support frame 200 in the folded state. At this time, the user can drive the triangular support frame 200 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100, so that the triangular support frame 200 extends out of the sleeve 300 through the bottom opening of the sleeve 300 to realize the unfolding of the triangular support frame 200 when the triangular support frame 200 moves along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 by a predetermined stroke.

[0052] As shown in Figure 7 , in particular, when the lock catch 410 is in the locked state, the lock catch part 412 can be clamped with the sliding seat 210 to hinder the sliding seat 210 from moving along the axial direction of the central pipe 100 relative to the central pipe 100 and the sleeve 300, thereby locking the triangular support frame 200 in the folded state in the sleeve 300.

[0053] As shown in Figure 7 and Figure 8 , the top end of the main body part 411 is rotatably arranged on the sleeve 300, in particular, the top end of the main body part 411 is rotatably arranged on the top end of the sleeve 300, the side surface of the main body part 411 away from the sleeve 300 is curved, and the thickness of the top end of the main body part 411 is greater than the thickness of the bottom end of the main body part 411.

[0054] The lock catch part 412 is arranged at the bottom end of the main body part 411 and located at the side of the main body part 411 towards the sleeve 300, the side surface of the lock catch part 412 towards the sleeve 300 is curved, so that the lock catch part 412 can more smoothly move into or out of the sleeve 300 through the through hole 320, and also can reduce the risk of scratching the surface of the sleeve 300 and the triangular support frame 200. In particular, in the embodiment, the main body part 411 and the lock catch part 412 are integrally formed, which facilitates the processing and forming of the lock catch 410.

[0055] The locking assembly 400 further comprises a second rotation shaft 420, and the main body part 411 is rotatably arranged on the sleeve 300 through the second rotation shaft 420, and the main body part 411 can rotate relative to the sleeve 300 around the axial direction of the second rotation shaft 420.

[0056] Specifically, the top end of the main body 411 is rotationally arranged on the sleeve 300 through the second rotating shaft 420, the top end of the sleeve 300 is provided with a second mounting groove 330, the second rotating shaft 420 is connected and arranged between the opposite two inner side walls of the second mounting groove 330, and the top end of the main body 411 is rotationally sleeved on the second rotating shaft 420.

[0057] As shown in Figure 8 , the locking assembly 400 further comprises a second elastic member 430, which is used to provide the main body 411 with elastic force, so that the main body 411 drives the lock catch 412 to rotate towards the direction close to the through hole 320, so that the lock catch 412 extends into the sleeve 300 through the through hole 320 and is clamped with the triangular support frame 200. Through the arrangement of the second elastic member 430, the lock catch 410 is in a natural state (i.e. no external force acts on the lock catch 410), the second elastic member 430 can drive the main body 411 to drive the lock catch 412 to rotate towards the direction close to the through hole 320 under the action of its own elastic force, so that the lock catch 412 extends into the sleeve 300 through the through hole 320 and is clamped with the triangular support frame 200, so as to switch the lock catch 410 to the locked state, thereby locking the triangular support frame 200 in the sleeve 300 in the folded state. In addition, when it is needed to switch the lock catch 410 from the locked state to the unlocked state, the external force of the user is used to overcome the elastic force of the second elastic member 430 acting on the main body 411, so as to drive the main body 411 to drive the lock catch 412 to rotate away from the through hole 320, so that the lock catch 412 extends out of the sleeve 300 through the through hole 320 and is separated from the triangular support frame 200.

[0058] Specifically, the second elastic member 430 can be a torsional spring, the second elastic member 430 is sleeved on the outside of the second rotating shaft 420, and the two ends of the second elastic member 430 abut against the main body 411. Further, the side of the main body 411 sleeved on one end of the second rotating shaft 420 (i.e. the top end of the main body 411) abuts against the inner side wall of the second mounting groove 330, and the second elastic member 430 is located between the opposite side of the main body 411 sleeved on one end of the second rotating shaft 420 and the opposite inner side wall of the second mounting groove 330. Further, the second elastic member 430 is arranged in the second mounting groove 330.

[0059] As shown in Figure 2 and Figure 7As shown, the tripod 10 further comprises a third elastic member 500, which is arranged in the sleeve 300 and is configured to drive the triangular support frame 200 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100. By arranging the third elastic member 500, the triangular support frame 200 can be automatically unfolded by the elastic force of the third elastic member 500 in the natural state (i.e. without external force acting on the triangular support frame 200), for example, after the user switches the lock catch 410 from the locked state to the unlocked state in some scenarios. The triangular support frame 200 can be driven by the elastic force of the third elastic member 500 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100, so that the triangular support frame 200 can be automatically unfolded by extending out of the sleeve 300 through the bottom end opening of the sleeve 300 during the process of continuously moving towards the bottom end of the central pipe 100 after moving along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 for a preset stroke, thereby improving the automation and convenience of the tripod 10. In addition, when it is necessary to switch the triangular support frame 200 from the unfolded state to the folded state, the user can overcome the elastic force of the third elastic member 500 acting on the triangular support frame 200 by external force to drive the triangular support frame 200 to move along the axial direction of the central pipe 100 and towards the top end of the central pipe 100, so that the triangular support frame 200 can be switched to the folded state and be retracted and stored in the sleeve 300 through the bottom end opening of the sleeve 300.

[0060] Specifically, the third elastic member 500 can be a compression spring, which is sleeved on the outer periphery of the central pipe 100, one end of the third elastic member 500 abuts against the inner wall of the top end of the sleeve 300, and the other end of the third elastic member 500 abuts against the sliding seat 210. The third elastic member 500 is configured to provide an elastic force to the sliding seat 210 to drive the sliding seat 210 to move along the axial direction of the central pipe 100 and towards the bottom end of the central pipe 100 relative to the central pipe 100 and the sleeve 300.

[0061] As shown, Figure 9 Further, the central pipe 100 comprises a plurality of connection pipes 110 which are sequentially sleeved, and one of the connection pipes 110 can be telescoped relative to the adjacent another connection pipe 110 along the axial direction of the central pipe 100, so that the support length of the central pipe 100 is adjustable along the axial direction of the central pipe 100. Specifically, during the photography or shooting process, the height of the photography equipment on the top end of the central pipe 100 often needs to be adjusted. By sequentially sleeving the plurality of connection pipes 110, the height adjustment of the photography equipment on the top end of the central pipe 100 can be achieved by adjusting the support length of the central pipe 100. In an embodiment, the top end of the central pipe 100 is configured to connect a gimbal, and the photography equipment can be installed on the gimbal.

[0062] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
