technical field

The invention relates to the technical field of photographic equipment, in particular to a foldable handle for locking a rotating structure on a photography platform or a photography tripod.

Background technique

In life, the use of photographic equipment is more and more extensive. People like to carry photographic equipment when they go out to take pictures on the road. In order to improve the convenience of carrying photographic equipment, people change the handle on the photographic equipment into a foldable handle. The handle can be folded up when carrying, thereby reducing the space occupied by photographic equipment.

For example, the Chinese patent document CN201583773U discloses a foldable handle, which includes a handle bar and a fixing part. The handle bar also includes a connecting part and a handle part, and the connecting part and the handle part are foldably and flexibly connected. The handle portion is fixed into a straight rod. That is to say, in the foldable handle described in the above-mentioned patent documents, the fixing part is set as a sleeve connected with the hand through threads. When the handle needs to be fixed in a straight line, the end of the sleeve away from the connecting part It only needs to cooperate with the thread of the hand; when the handle needs to be folded, the sleeve is rotated so that the end of the sleeve close to the connecting part matches the thread of the hand, and then the hand can be folded by rotating the handle.

The disadvantage of the foldable handle described in the above-mentioned patent documents is that in the foldable handle, the connection part and the handle part are connected by a rotating shaft. , by turning the sleeve threadedly connected to the handle to move forward, so that the connecting part and the connecting end of the handle part are in the sleeve and cannot be bent; when the handle needs to be folded, it is necessary to twist the sleeve to move back one end distance, the whole The process is cumbersome to operate and inconvenient to use, and the connecting part of the straight rod and the handle part will shake slightly in the sleeve. When using it, the hand feel is not good, especially after long-term use, the shaking is caused by the sleeve. The wear and tear of various parts is more obvious.

A chute 12 extending in the axial direction is formed on the side wall of the accommodating cavity 11 for insertion of the end of the rotating shaft 3, and the connecting end of the locking rod 2 extends into the accommodating cavity 11 to reciprocate Sliding; and the shape of the port of the accommodation chamber 11 is suitable for the locking rod 2 to rotate and fold around the rotating shaft 3. In this embodiment, the chute 12 is preferably symmetrically arranged in two; the locking structure includes The backstop through hole 13 formed on the side wall of the handle rod 1, the backstop pin hole 21 formed on the locking rod 2, the backstop pin arranged in the backstop pin hole 21 22 and a biasing member 23, and the biasing force of the biasing member 23 causes one end of the backstop pin 22 to be inserted into the backstop through hole 13; when the backstop pin 22 is pressed, it can overcome The biasing force retreats into the back-stop pin hole 21 . When it is necessary to fix the handle rod 1 and the locking rod 2 in a straight line, it is only necessary to push the connecting end of the locking rod 2 into the accommodating chamber 11. During the pushing process, when the When the backstop pin 22 is aligned with the backstop through hole 13 on the handle rod, under the action of the biasing member 23, it is inserted into the backstop through hole 13, that is, they are connected in a straight line. The handle bar 1 and the locking bar 2 are locked in the state; when the handle needs to be folded, just press the anti-back pin 22 so that it withdraws from the anti-back through hole 13 for unlocking and locking. The locking rod 2 is stretched outward, and can be rotated and folded around the rotating shaft 3; the device is simple and convenient to operate, and the locking of the linear connection state is reliable, and will not vibrate during use.

In this embodiment, in order to make the operation feel comfortable, an elastic button structure is also provided. The elastic button structure includes an elastic plate 4 that is connected to the handle rod 1 at one end and an elastic button post 41 at the other end. The elastic button column 41 is aligned with the anti-retreat through hole 13, and can resist the anti-retreat pin 22 to exit the anti-retreat through hole 13 under pressure, and the insertion end of the elastic button column 41 does not expose the Out of the through hole 13.

In this embodiment, the biasing member 23 can be configured as a spring. In order to facilitate the installation of the backstop pin 22 and the biasing member 23, the backstop pin hole 21 is set as a through hole, and the lower port of the backstop pin hole 21 is provided with a detachable end port. Cover 24 , the lower end of the biasing member 23 is set against the end cover 24 .

The shape of the port of the accommodating chamber 11 is: the port of the accommodating chamber 11 is in the shape of a round tube, and the left and right sides of the round tube-shaped port are formed with holes suitable for the locking rod 2 to rotate around the rotating shaft 3 to fold and snap in. U-shaped notch; at the same time, an insertion groove 25 extending in the axial direction is formed on the left and right side walls of the locking rod 2, and the insertion groove 25 is suitable for both sides of the U-shaped notch at the port of the accommodating cavity 11 The side wall is inserted; in this way, the connection between the locking rod 2 and the handle rod 1 can be strengthened, and the connection strength between the two can be strengthened, so that the connection between the two can bear a relatively large rotational torque.

Example 2

As shown in Figure 2, in this embodiment, a groove 14 suitable for pressing the pad of a finger is formed on the side wall where the through hole 13 of the handle rod 1 is located, to replace the With the unique elastic button structure, when the handle is folded, it is only necessary to press the backstop pin 22 to make it exit the backstop through hole 13, the structure is simpler and the handle is more comfortable.
