[0035] Please refer to Figure 1 and Figure 2 This embodiment provides a rocker arm movable body 200, and the rocker arm movable body 200 includes a counterweight body 210 and a locking member 220;

[0036] The counterweight body 210 is used to be slidably connected to the operating rod 110 ; the locking member 220 is connected to the counterweight body 210 and is used to abut against the operating rod 110 to limit the sliding of the counterweight body 210 relative to the operating rod 110 .

[0037] Please refer to Figure 1 and Figure 2 The working principle of the rocker arm traveler 200 is:

[0038] The rocker arm movable body 200 is used for a telescopic rocker arm for photography, and the telescopic rocker arm for photography includes a frame, a rocker arm body and the rocker arm movable body 200; wherein the rocker arm body and the frame are movably connected, and this embodiment is described by taking the rocker arm body and the frame as an example of being hinged, and the photographic equipment is connected to the rocker arm body, and the rocker arm body is provided with an operating rod 110, and the hinged part of the rocker arm body and the frame is located between the operating rod 110 and the photographic equipment, thereby, the balance of the telescopic rocker arm for photography can be achieved by connecting the rocker arm movable body 200 to the operating rod 110;

[0039] Moreover, during the balancing process, the rocker arm movable body 200 is slid relative to the operating rod 110. During the sliding process, the locking member 220 is threadedly connected to the counterweight body 210 in this embodiment. Therefore, the locking member 220 can be rotated to disengage the counterweight body 210 from the operating rod 110, so that the counterweight body 210 can slide relative to the operating rod 110, thereby adjusting its balance. After it is adjusted to a suitable balancing position, the locking member 220 can be rotated to abut against the operating rod 110, so that the sliding of the counterweight body 210 relative to the operating rod 110 is restricted, so as to maintain the position of the counterweight body 210 relative to the operating rod 110, so that the rocker arm body can achieve perfect balance during use, so as to reduce the difficulty of operating the telescopic rocker arm for photography in this way.

[0040] Thus, the balance of the photographic telescopic arm can be adjusted by sliding the arm swing 200 relative to the operating rod 110, so that slight horizontal differences can be flexibly adjusted to achieve perfect balance, thereby improving the feel during operation, reducing the difficulty of operation, and also being beneficial to improving the quality of photography; and in the adjustment process, compared with the method of adjusting the balance by adding or removing counterweights in the prior art, the method of adjusting the balance by sliding can make the balancing process of the photographic telescopic arm flexible and convenient, avoid repeated adjustments due to adding or removing counterweights, thereby improving the adjustment convenience and flexibility of the photographic telescopic arm.

[0041] For further information, please refer to Figure 1 and Figure 2 In this embodiment, in order to facilitate the connection between the rocker arm movable body 200 and the operating rod 110, the counterweight body 210 includes a connecting piece 230, a first counterweight block 240 and a second counterweight block 250. The first counterweight block 240 and the second counterweight block 250 are connected by the connecting piece 230, and the first counterweight block 240 and the second counterweight block 250 are respectively provided with a first semicircular groove 241 and a second semicircular groove 251;

[0042] The first semicircular groove 241 is opposite to the second semicircular groove 251 , and the first semicircular groove 241 and the second semicircular groove 251 together form a channel 201 that is slidably matched with the operating rod 110 .

[0043] It should be noted that, through the arrangement of the first counterweight block 240 and the second counterweight block 250, the counterweight body 210 can be divided into two parts to facilitate its assembly on the operating rod 110, and the first semicircular groove 241 and the second semicircular groove 251 of the counterweight body 210 together form a channel 201 that slides with the operating rod 110, thereby enabling its sliding fit with the operating rod 110, and when configuring the channel 201, the inner diameter of the channel 201 can be greater than or equal to the outer diameter of the operating rod 110.

[0044] Please refer to Figure 1 and Figure 2 When connecting the first counterweight block 240 and the second counterweight block 250, this embodiment adopts a method of threaded connection between the connecting piece 230 and the first counterweight block 240 and the second counterweight block 250 to achieve a detachable connection between the first counterweight block 240 and the second counterweight block 250. Therefore, in order to facilitate the connection between the first counterweight block 240 and the second counterweight block 250 and the connecting piece 230, the first counterweight block 240 and the second counterweight block 250 are both provided with connecting holes for installing the connecting piece 230.

[0045] In addition, when the locking member 220 is installed, the function of the locking member 220 is to adjust the sliding state of the counterweight body 210 relative to the operating rod 110, so the first counterweight block 240 or the second counterweight block 250 is provided with a through locking hole, and the locking member 220 is threadedly connected to the locking hole; wherein the locking hole is connected to the first semicircular groove 241 or the second semicircular groove 251. Thus, by rotating the locking member 220, the distance that the locking member 220 extends into the channel 201 can be adjusted, thereby changing the abutting state between the locking member 220 and the operating rod 110.

[0046] For further information, please refer to Figure 1-Figure 3 In this embodiment, in order to adjust the weight of the counterweight body 210 to adjust its leveling range and increase the flexibility of the telescopic rocker arm, the first counterweight block 240 or the second counterweight block 250 includes a plurality of arc-shaped sub-blocks 242 connected in sequence. Moreover, the connection between adjacent arc-shaped sub-blocks 242 is a detachable connection, so that the weight of the counterweight body 210 can be adjusted in this way.

[0047] In order to make the connection between adjacent arcuate sub-blocks 242 a detachable connection, each arcuate sub-block 242 can be provided with at least four through positioning holes 243; and each arcuate sub-block 242 corresponds to two connecting studs 244, the two connecting studs 244 cooperate with any two positioning holes 243, and each connecting stud 244 is threadedly connected to the positioning hole 243 of the corresponding arcuate sub-block 242 and the positioning hole 243 of the adjacent arcuate sub-block 242.

[0048] Thus, when connecting two adjacent arc-shaped sub-blocks 242, two connecting studs 244 corresponding to one of the arc-shaped sub-blocks 242 can be threadedly connected to two of the positioning holes 243, and the connecting studs 244 can be rotated to extend into the two positioning holes 243 of the adjacent arc-shaped sub-blocks 242 and threadedly connected thereto, thereby achieving the connection of the two adjacent arc-shaped sub-blocks 242. After that, when connecting to another arc-shaped sub-block 242, the connecting studs 244 can be staggered, that is, the connecting studs 244 are threadedly connected to the positioning holes 243 that are not connected to the connecting studs 244, thereby achieving the detachable connection between the multiple arc-shaped sub-blocks 242. When such a setting is adopted, the four positioning holes 243 are arranged at intervals around the curved center line of the arc-shaped sub-block 242.

[0049] In other embodiments of the present invention, please refer to Figure 4 , and combined with Figure 1 and Figure 2 , it is also possible to adopt that each arc-shaped sub-block 242 is provided with two through positioning holes 243; each arc-shaped sub-block 242 corresponds to two connecting studs 244, the two connecting studs 244 cooperate with the two positioning holes 243, and each connecting stud 244 is threadedly connected with the corresponding positioning hole 243 of the arc-shaped sub-block 242 and the positioning hole 243 of the adjacent arc-shaped sub-block 242. Thus, each connecting stud 244 can be connected with the corresponding communicating positioning holes 243 of two adjacent arc-shaped sub-blocks 242, that is, a part of each connecting stud 244 is threadedly connected with the positioning hole 243 of one arc-shaped sub-block 242, and the rest of the part is threadedly connected with the positioning hole 243 of the adjacent arc-shaped sub-block 242. In this arrangement, two connecting studs 244 can be threadedly connected in each positioning hole 243. Therefore, when such a connection method is adopted, the length of the connecting stud 244 needs to be less than the length of the positioning hole 243.

[0050] It should be noted that, in the above content, the application of the rocker arm traveler 200 to a photographic telescopic rocker arm is used as an example for explanation, and in other embodiments of the utility model, the rocker arm traveler 200 can also be applied to other types of photographic rockers.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
