SLIDING BLOCK OF ANGLE-ADJUSTABLE PHOTOGRAPHIC SLIDING RAIL

Abstract

A sliding block of an angle-adjustable photographic sliding rail comprises a sliding block body, an angle adjustment plate having one end swingingly connected on the sliding block body via a rotating shaft, and a stepless adjustment strutting structure arranged between the sliding block body and the angle adjustment plate. When the photographic sliding rail cannot be put in place and needs to be tilted for use, the stepless adjustment strutting structure can be loosened first, and then the angle adjustment plate can be swung and opened such that a lens of a camera or video camera on the angle adjustment plate is at a horizontal position, to achieve the angle adjustment of the angle adjustment plate.

DETAILED DESCRIPTION

[0016] The present invention is a sliding block of an angle-adjustable photographic sliding rail, as shown in FIG. 1 to FIG. 4, including a sliding block body 1, an angle adjustment plate 2 having one end swingingly connected to the sliding block body 1 through a rotating shaft 6, and a stepless adjustment strutting structure 4 arranged between the sliding block body 1 and the angle adjustment plate 2. When a photographic sliding rail 5 installed with this photographic sliding block is in used, a camera or video camera is mounted on the angle adjustment plate 2, at this time if the sliding rail cannot be put in place and needs to be tilted for use, the stepless adjustment strutting structure 4 can be loosened, then the angle adjustment plate 2 can be swung and opened, and, when a lens of the camera or video camera on the angle adjustment plate is adjusted to a horizontal position, the stepless adjustment strutting structure 4 is tightened, to achieve the angle adjustment of the angle adjustment plate 2. From the above, it can seen that, when people use a photographic sliding rail installed with the sliding block of an angle-adjustable photographic sliding rail, there is no need to carry an additional horizontal adjustment tripod head, and thus will not delay the best time for shooting caused by the repeated assembly and disassembly of the horizontal adjustment tripod head; therefore, the present invention has a reasonable structure, and, when it is applied to a photographic sliding rail, a photographing lens can be ensured to be always in a horizontal state by adjusting the sliding block.

[0017] In this embodiment, as shown in FIG. 3, the stepless adjustment strutting structure 4 includes a strut rod 41 with one end swingingly connected to the angle adjustment plate 2, a bolt 42 penetrating through a horizontal hole 11 of the sliding block body 1 and a strip shaped hole 411 on the other end of the strut rod 41, and a tilted locking knob 43 screwed on the bolt 42 to lock the adjustment plate that is in an open state. During operations, the tilted locking knob 43 is turned first to loosen the bolt 42, such that the angle adjustment plate 2 can be opened. With the strip shaped hole 411 of the strut rod 41 slides along the bolt 42, the stepless adjustment can be achieved. When the angle adjustment plate 2 is opened to a desired angle, the tilted locking knob 43 is reversely turned to tighten the bolt 42, so as to lock the adjustment plate. Of course, the stepless adjustment strutting structure 4 also may be of other structures, for example, opening an retractable adjustment plate by way of, similar to, jack.

[0018] Preferably, a horizontal locking plate structure 3 for locking the angle adjustment plate 2 in a horizontal state is arranged on the sliding block body 1. During manipulating the stepless adjustment strutting structure 4, it is need to operate the horizontal locking plate structure 3 firstly so as to release the locking of the angle adjustment plate 2, and then to loosen the stepless adjustment strutting structure 4 to implement angle adjustment. In this embodiment, as shown in FIG. 3 and FIG. 4, the horizontal locking plate structure 3 includes a horizontal lock catch 31 vertically swingingly connected in an open slot 12 of the sliding block body 1, and a lock catch spring 32 for putting the horizontal lock catch 31 in place to buckle the angle adjustment plate 2. During unlocking, the lower end of the horizontal lock catch 31 is pressed to make its hook part disengage from a hook platform 21 of the adjustment plate, and then the horizontal locking of the adjustment plate is released.

[0019] The above descriptions are merely preferred embodiments of the disclosure and are not intended to limit the implementation scope of the disclosure. All equivalent changes and modifications made according to the content within the patent scope claimed by the disclosure are intended to be included in the technical scope of the disclosure.
