If the specific posture changes, the directional indication will also change accordingly.

[0041] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0042] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] The present invention provides a tripod head hand-smashing protection device, the tripod head hand-smashing protection device comprising:

[0044] A lifting shaft 1, the top end of which is used to connect with the pan / tilt head;

[0045] The buffer component 2 can be in contact with the bottom of the lifting shaft 1. The buffer component 2 is configured to generate a reaction force when the lifting shaft 1 is subjected to axial pressure, so as to decelerate the lifting shaft 1 when it falls along the axis.

[0046] like Figures 1 to 7As shown, the tripod head anti-smashing device can be composed of a lifting shaft 1 and a buffer assembly 2. The top end of the lifting shaft 1 can be used to install the head; the lifting shaft 1 can be lifted and lowered inside the buffer assembly 2 to adjust the height of the head. The buffer assembly 2 can also be connected to a tripod; wherein the tripod can be fixed on the outer side wall of the buffer assembly 2. The tripod head anti-smashing device can also include a locking structure, which is used to lock the lifting and lowering movement of the lifting shaft 1 to fix the height of the head. The head has a certain weight and generates gravity; when the head is raised by the lifting shaft 1, the lifting shaft 1 will be affected by the gravity generated by the head, so that the lifting shaft 1 is subjected to downward axial pressure; at this time, the locking structure can be used to lock the lifting shaft 1 to prevent the lifting shaft 1 from sliding downward.

[0047] However, in daily use, users may be careless and unlock the locking structure without noticing. At this time, the lifting shaft 1 will slide downward. When the lifting shaft 1 slides downward, the buffer component 2 can generate a reaction force for the lifting shaft 1 to slow down the lifting shaft 1 when it falls along the axis, thereby avoiding hurting the user's hand.

[0048] In some embodiments, the buffer component 2 includes:

[0049] A first sleeve 21, wherein one end of the first sleeve 21 is open and the other end is closed;

[0050] The oil pressure buffer 22 includes a cylinder body 221 and a piston rod 222 extending from the cylinder body 221 . The piston rod 222 is provided with a piston head 223 . The piston head 223 can abut against the bottom of the lifting shaft 1 . The cylinder body 221 is at least partially accommodated in the first sleeve 21 .

[0051] In this embodiment, if Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the buffer assembly 2 may be composed of a first sleeve 21 and an oil pressure buffer 22. The tripod may be fixed to the outer side wall of the first sleeve 21. The top end of the first sleeve 21 is open, and the bottom end of the first sleeve 21 is closed. The oil pressure buffer 22 may be composed of a cylinder 221 and a piston rod 222. A buffer liquid may be disposed inside the cylinder 221, wherein the buffer liquid may be buffer oil, and of course the type of the buffer liquid is not limited in this embodiment.

[0052] The piston rod 222 extends from the inside of the cylinder body 221, and a piston head 223 may be provided at the top of the piston rod 222. When the piston head 223 is subjected to pressure, the pressure may be transmitted to the piston rod 222; at this time, the piston rod 222 will move into the cylinder body 221, thereby compressing the buffer oil inside the cylinder body 221, and at this time, the compressed buffer oil will generate a reaction force, thereby offsetting or partially offsetting the pressure of the piston rod 222, so as to reduce the pressure effect on the piston head 223. The piston head 223 may abut against the bottom of the lifting shaft 1, and at this time, the axial pressure on the lifting shaft 1 will be transmitted to the piston head 223. Since the bottom end of the first sleeve 21 is closed, the first sleeve 21 has an inner bottom end. The cylinder body 221 is at least partially accommodated in the first sleeve 21; wherein, the bottom of the cylinder body 221 may abut against the inner bottom end of the first sleeve 21, and the bottom of the cylinder body 221 may also be separated from the inner bottom end of the first sleeve 21.

[0053] In some embodiments, the first sleeve 21 is sleeved with the lifting shaft 1, and the lifting shaft 1 can slide along the first sleeve 21;

[0054] The buffer component 2 also includes:

[0055] A mounting seat 23, the mounting seat 23 is connected to the bottom of the lifting shaft 1, and a first contact block 24 and a second contact block 25 are arranged on opposite sides of the mounting seat 23, and the first contact block 24 and the second contact block 25 are both flip-connected to the mounting seat 23 through a rotating shaft;

[0056] When the lifting shaft 1 is in an initial state without force, the first contact block 24 and the second contact block 25 are exposed at the pipe mouth of the first sleeve 21; when the lifting shaft 1 is subjected to axial pressure, the first contact block 24 and the second contact block 25 are squeezed by the inner wall of the first sleeve 21 and flipped inward to abut against the piston head 223.

[0057] In this embodiment, if Figure 3 , Figure 6 and Figure 7 As shown, the first sleeve 21 is sleeved with the lifting shaft 1, and the lifting shaft 1 can slide along the first sleeve 21, so that the lifting shaft 1 can be lifted and lowered in the first sleeve 21. The buffer assembly 2 may also include a mounting seat 23, a first contact block 24, and a second contact block 25. The bottom of the lifting shaft 1 is sleeved with the mounting seat 23, so that the bottom of the lifting shaft 1 is connected to the mounting seat 23. The first contact block 24 and the second contact block 25 are both flip-connected with the mounting seat 23 through a rotating shaft.

[0058] The side wall of the mounting seat 23 is provided with two opposite mounting seat notches, and the first contact block 24 and the second contact block 25 are both connected to the mounting seat 23 by a rotating shaft, and the first contact block 24 and the second contact block 25 are respectively installed on the two opposite mounting seat notches; the first contact block 24 and the second contact block 25 can both be turned and moved in the mounting seat notches. Moreover, one side of the first contact block 24 also extends out from the inside of the mounting seat 23 through the mounting seat notch; similarly, one side of the second contact block 25 also extends out from the inside of the mounting seat 23 through the mounting seat notch.

[0059] Two opposite lifting shaft notches are also provided on the side wall at the bottom of the lifting shaft 1; when the bottom of the lifting shaft 1 is sleeved with the mounting seat 23, one side of the first contact block 24 also extends out from the inside of the lifting shaft 1 through the lifting shaft notch, and similarly, one side of the second contact block 25 also extends out from the inside of the lifting shaft 1 through the lifting shaft notch. When the bottom of the lifting shaft 1 is sleeved with the mounting seat 23, the first contact block 24 and the second contact block 25 can clamp and fix the lifting shaft 1 on the mounting seat 23.

[0060] When the lifting shaft 1 is in an initial state without force (ie, the lifting shaft 1 is locked by the locking structure), the lifting shaft 1 does not slide downward. At this time, the first contact block 24 and the second contact block 25 are exposed at the pipe opening of the first sleeve 21 .

[0061] When the lifting shaft 1 is subjected to axial pressure (i.e., when the locking structure that locks the lifting shaft 1 is unlocked), the lifting shaft 1 will slide downward, and the lifting shaft 1 will drive the mounting seat 23 to slide downward, thereby entering the first sleeve 21. At this time, the first contact block 24 and the second contact block 25 will be squeezed by the inner wall of the first sleeve 21 and flip inward to abut against the piston head 223. When the first contact block 24 and the second contact block 25 are squeezed by the inner wall of the first sleeve 21, a part of the axial pressure of the lifting shaft 1 can be consumed; the remaining axial pressure can be transmitted to the piston head 223 through the first contact block 24 and the second contact block 25.

[0062] In some embodiments, the buffer component 2 further includes:

[0063] A first restoring member 26, wherein one end of the first restoring member 26 abuts against the first contact block 24, and the other end of the first restoring member 26 abuts against the mounting seat 23;

[0064] The second restoring member 27 has one end abutting against the second contact block 25 , and the other end abutting against the mounting seat 23 .

[0065] In this embodiment, if Figure 3 , Figure 6 and Figure 7As shown, the buffer assembly 2 may further include a first reset member 26 and a second reset member 27. One end of the first reset member 26 abuts against the first contact block 24, and the other end abuts against the mounting seat 23; one end of the second reset member 27 abuts against the second contact block 25, and the other end abuts against the mounting seat 23.

[0066] The first reset member 26 and the second reset member 27 can both be compression springs. In this embodiment, Figure 3 The compression spring in the Figure 6 The compression spring in is in a compressed state. Figure 3 The state of the first contact block 24 in the embodiment is a plane state. Figure 6 The state of the first contact block 24 in the embodiment is a convex state; similarly, Figure 3 The state of the second contact block 25 in the embodiment is a plane state. Figure 6 The state of the second contact block 25 is a convex state.

[0067] The first reset member 26 can make the first contact block 24 stay in a plane state, and similarly, the second reset member 27 can make the second contact block 25 stay in a plane state; thereby, the first contact block 24 and the second contact block 25 will not become a convex state when inside the first sleeve 21. When the first contact block 24 and the second contact block 25 slide inside the first sleeve 21, they can slide smoothly and will not become a convex state, thereby hindering the sliding.

[0068] In some embodiments, the first contact block 24 is arranged in a polygonal shape, with a connecting hole in the middle portion for flipping and connecting with the mounting seat 23, and the circumferential side includes a pressure-bearing surface, a top surface and a reset surface which are connected in sequence, the pressure-bearing surface is used to contact the inner wall of the first sleeve 21, the top surface is used to contact the piston head 223, the reset surface is used to contact the first reset member 26, and the pressure-bearing surface portion is divided into an inclined surface.

[0069] In this embodiment, if Figure 3 , Figure 6 and Figure 7 As shown, the pressure-bearing surface and the top surface are two parallel planes, and the pressure-bearing surface is an inclined surface when compared with the pressure-bearing surface. The first contact block 24 is provided with a connecting hole in the middle, and the first contact block 24 is flipped and connected with the mounting seat 23 through the connecting hole. The peripheral side of the first contact block 24 includes a pressure-bearing surface, a top surface and a reset surface that are connected in sequence; and the plane where the pressure-bearing surface is located is parallel to the connecting hole. Similarly, the plane where the top surface is located and the plane where the reset surface is located are also parallel to the connecting hole. The pressure-bearing surface is used to contact the inner wall of the first sleeve 21, the top surface is used to contact the piston head 223, and the reset surface is used to contact the first reset member 26.

[0070] In some embodiments, the buffer assembly 2 further includes a locking mechanism, and the locking mechanism includes:

[0071] A second sleeve 281, the mounting seat 23 is connected to the top end of the second sleeve 281, and the piston head 223 is accommodated in the second sleeve 281;

[0072] A mounting sleeve 282, the top of which is connected to the piston head 223, and the bottom of which is sleeved with the piston rod 222, the outer wall of which is provided with a locking tongue 283 which can be turned relative to the piston rod 222, the inner wall of the second sleeve 281 is provided with a convex block 284 which contacts the locking tongue 283, and the convex block 284 is constructed with an inclined surface which places the locking tongue 283 in an unlocking position and a flat surface which places the locking tongue 283 in a locking position;

[0073] The mounting rod 285 has one end radially passing through the mounting sleeve 282 and abutting against the locking tongue 283, and the other end of the mounting rod 285 is provided with a roller 286. The side wall of the second sleeve 281 is provided with a first notch 2811, and the roller 286 is arranged toward the first notch 2811 and can move back and forth in the first notch 2811.

[0074] In this embodiment, if Figure 3 , Figure 6 and Figure 7 As shown, the buffer assembly 2 may further include a locking mechanism and a bolt 231. The locking mechanism may be composed of a second sleeve 281, a mounting sleeve 282, a locking tongue 283, a protrusion 284, a mounting rod 285 and a roller 286. The mounting seat 23 is connected to the top end of the second sleeve 281 and fixed by a bolt 231. The piston head 223 is accommodated inside the second sleeve 281. The piston head 223 is connected to the piston rod 222 through the mounting sleeve 282. The outer wall of the mounting sleeve 282 is provided with a locking tongue 283 that can be turned relative to the piston rod 222. The inner wall of the second sleeve 281 is provided with a protrusion 284 that contacts the locking tongue 283, and the protrusion 284 is constructed with an inclined surface that makes the locking tongue 283 in an unlocking position and a plane that makes the locking tongue 283 in a locking position.

[0075] The first contact block 24 and the second contact block 25 will be pressed by the inner wall of the first sleeve 21 to turn inward and abut against the piston head 223. The first contact block 24 and the second contact block 25 will push the piston head 223 to move downward. At this time, the installation sleeve 282 will also move downward, thereby pulling the lock tongue 283 to move downward, so that the lock tongue 283 moves to the plane of the locking position; at this time, the protrusion 284 locks the lock tongue 283, so that the installation sleeve 282 and the piston head 223 are also locked; at this time, the reaction force generated by the piston rod 222 cannot act on the first contact block 24 and the second contact block 25, that is, when the piston head 223 is locked, the piston head 223 cannot push the first contact block 24 and the second contact block 25. When the first reset member 26 and the second reset member 27 slide inside the first sleeve 21, they can slide smoothly and will not become a convex state, thereby hindering sliding.

[0076] One end of the mounting rod 285 radially passes through the mounting sleeve 282 and abuts against the locking tongue 283, and the other end of the mounting rod 285 is provided with a roller 286. The side wall of the second sleeve 281 is provided with a first notch 2811, and the roller 286 is arranged toward the first notch 2811 and can reciprocate in the first notch 2811. When the roller 286 is pushed into the first notch 2811, the roller 286 pushes the mounting rod 285, thereby pushing the locking tongue 283, so that the locking tongue 283 moves to the inclined surface of the unlocking position.

[0077] When the lifting shaft is pulled out and the roller 286 is pulled out of the tube mouth of the first sleeve 21, the roller 286 can be pushed into the first notch 2811, thereby pushing the locking tongue 283 by pushing the installation rod 285, so that the locking tongue 283 moves to the inclined surface of the unlocking position; at this time, the reaction force generated by the piston rod 222 can act on the first contact block 24 and the second contact block 25, that is, when the piston head 223 is unlocked, the piston head 223 can push the first contact block 24 and the second contact block 25 in reverse, so that the first contact block 24 and the second contact block 25 become a convex state when they are outside the tube mouth of the first sleeve 21. Among them, it is assumed that the reaction force generated by the piston rod 222 is greater than the force when the first reset member 26 and the second reset member 27 are compressed; the reaction force generated by the piston rod 222 can compress the first reset member 26 and the second reset member 27.

[0078] In some embodiments, the side wall of the second sleeve 281 is provided with a second notch 2812 opposite to the first notch 2811 for the reciprocating movement of the locking tongue 283 .

[0079] In this embodiment, if Figure 3 , Figure 6 and Figure 7As shown, the side wall of the second sleeve 281 is further provided with a second notch 2812; wherein the second notch 2812 is opposite to the first notch 2811, and the second notch 2812 is used for the reciprocating movement of the lock tongue 283; when the lock tongue 283 moves to the plane of the protrusion 284 that makes the lock tongue 283 in the locking position, the lock tongue 283 is located inside the second notch 2812. When the lock tongue 283 moves to the inclined surface of the protrusion 284 that makes the lock tongue 283 in the unlocking position, one end of the lock tongue 283 is located outside the second notch 2812.

[0080] In some embodiments, the locking mechanism further includes: a lock tongue reset member 287, which is disposed on a side wall of the lock tongue 283 and is used to reset the lock tongue 283 from the inclined surface of the unlocking position to the flat surface of the locking position.

[0081] In this embodiment, if Figure 7 As shown, the locking mechanism also includes a lock tongue reset member 287, wherein the lock tongue reset member 287 can be a right-angle spring; the lock tongue reset member 287 is arranged on the side wall of the lock tongue 283, and is used to reset the lock tongue 283 from the inclined surface of the unlocking position to the plane of the locking position. When the installation sleeve 282 pulls the lock tongue 283 to move downward, the lock tongue reset member 287 will also act on the lock tongue 283, thereby accelerating the speed of the lock tongue 283 from the inclined surface of the unlocking position to the plane of the locking position. At the same time, the lock tongue reset member 287 will also make the lock tongue 283 stay on the plane of the locking position; so that the lock tongue 283 will not be at the inclined surface of the unlocking position when it is not pushed by the installation rod 285. Therefore, when the roller 286 is not pulled out of the pipe mouth of the first sleeve 21, the lock tongue 283 will not be at the inclined surface of the unlocking position.

[0082] In some embodiments, the mounting rod 285 is provided with a limiting structure for limiting the reciprocating motion range of the roller 286 .

[0083] In this embodiment, a limiting structure for limiting the reciprocating motion range of the roller 286 is provided on the mounting rod 285 to prevent the roller 286 from moving too far and falling out of the first notch 2811 .

[0084] In some embodiments, the limiting structure includes a slide groove 291 located on the mounting rod 285 , and a limiting pin 292 fixed on the second sleeve 281 and capable of extending into the slide groove 291 .

[0085] In this embodiment, if Figure 3 , Figure 6 and Figure 7As shown, the limiting structure includes a slide groove 291 and a limiting pin 292. The slide groove 291 is arranged on the mounting rod 285. The limiting pin 292 is fixed on the second sleeve 281, and the limiting pin 292 can extend into the slide groove 291; the slide groove 291 and the limiting pin 292 work together to limit the reciprocating range of the roller 286, and prevent the roller 286 from falling out of the first notch 2811.

[0086] To summarize, the present invention arranges a buffer component in the lifting shaft, so that when the user suddenly unlocks the gimbal and lowers it, the lifting shaft will be subjected to axial pressure and fall downward, and the buffer component will generate a reaction force to decelerate the lifting shaft when falling along the axis, thereby reducing the speed at which the gimbal slides downward, and effectively preventing the problem of the gimbal sliding downward quickly and injuring hands.
