Description

Technical Field

[0001] The utility model relates to a support, in particular to a support with adjustable angle. Background Art

[0002] The photography fill light plays an important role in providing auxiliary light sources in shooting environments with insufficient light, so as to ensure that the photographer can capture high-quality image materials. In order to achieve convenient adjustment of the lighting angle of the lamp, an adjustable angle bracket is usually arranged between the fill light and the light stand. Among them, an adjustable angle bracket of the prior art is composed of a fixed part, a movable part, and a locking mechanism placed between the fixed part and the movable part. This locking mechanism contains two mutually meshing locking member groups and a spring for applying elastic force to the two locking member groups. When the angle of the fill light needs to be adjusted, the photographer will loosen the locking screws of the two locking member groups, adjust to a suitable angle, and then tighten the screws again to fix the position.

[0003] However, although this design facilitates the adjustment of the fill light angle to a certain extent, in the locked state, once a large torque is applied between the fixed part and the movable part, the locking part may jump out of the teeth, which will reduce the position stability of the fill light.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See also Figure 1 The angle-adjustable support in one embodiment of the utility model comprises: a fixed seat 10, a movable seat 20 and a locking mechanism 30, wherein a first joint 11 is provided at the lower end of the fixed seat 10. As an example, the first joint 11 is a screw hole ( Figure 4), the screw hole can cooperate with the screw on the bracket (not shown in the figure) to install the support on the bracket.

[0035] The upper end of the movable seat 20 is provided with a second joint 21. As an example, the second joint 21 is a screw ( Figure 2 ), the screw cooperates with the screw hole of accessories such as the fill light (not shown in the figure) to install the accessories such as the fill light on the support.

[0036] Also refer to Figure 2 , Figure 4 and Figure 6 The lower end of the movable seat 20 is rotatably connected to the upper end of the fixed seat 10 through a first rotating shaft. As an example, the movable seat 20 is composed of a first shell 22 and a second shell 23 that are buckled together. The first rotating shaft includes a cylindrical first shaft portion 221 arranged at the lower end of the first shell 22 and a cylindrical second shaft portion 231 arranged at the lower end of the second shell 23. The other end of the fixed seat 10 is provided with an axis hole 101, and the first axis portion 221 and the second axis portion 231 are respectively inserted into the axis hole 101 from both ends of the axis hole 101, and the two are locked by screws 37.

[0037] The locking mechanism 30 includes a first locking member 12, a second locking member 31, a button 33 and a self-locking member 34. The first locking member 12 is disposed at the upper end of the fixing seat 10 and has a plurality of first teeth 121. As an example, the first locking member 12 is integrally disposed at the upper end of the fixing seat 10 and is cylindrically extended in the radial direction. The outer peripheral surface of the first locking member 12 is provided with a plurality of first teeth 121.

[0038] The second locking member 31 is disposed at the lower end of the movable seat 20 and can move between an unlocking position and a locking position, and has a plurality of second teeth 311 that cooperate with the first teeth 121. As an example, the second locking member 31 is block-shaped, and a plurality of second teeth 311 are disposed on one side of the second locking member 31.

[0039] The button 33 is movably disposed on the movable seat 20 , and has a first active portion 331 and a second active portion 332 . The second locking member 31 is provided with a first driven portion 312 that cooperates with the first active portion 331 .

[0040] The self-locking member 34 is movably disposed on the movable seat 20 , and has a second driven portion 341 and a first locking portion 342 . The second driven portion 341 cooperates with the second active portion 332 . The second locking member 31 is provided with a second locking portion 313 that cooperates with the first locking portion 342 .

[0041] Also refer to Figure 6 and Figure 7 , when the button 33 is in the natural state ( Figure 6), the first tooth 121 of the first locking member 12 and the second tooth 311 of the second locking member 31 are meshed with each other, and the first locking portion 342 and the second locking portion 313 cooperate with each other to prevent the second locking member 31 from moving. At this time, the movable seat 20 cannot be rotated, so that the angle of the movable seat 20 cannot be adjusted; when the button 33 is pressed, the second active portion 332 cooperates with the second driven portion 341 to separate the first locking portion 342 from the second locking portion 313 to release the lock of the second locking member 31, and the second locking member 31 is separated from the first locking member 12 by the cooperation of the first active portion 331 and the first driven portion 312 ( Figure 7 ), at this time, the angle of the movable seat 20 can be adjusted.

[0042] When using the angle-adjustable support in this embodiment, the user can unlock the second locking member 31 by pressing the button 33, so that the second tooth 311 of the second locking member 31 is separated from the first tooth 121 of the first locking member 12, thereby allowing the movable seat 20 to rotate around the first rotating shaft 221 to adjust the angle of the support. When the button 33 is released, the self-locking member 34 will drive the second locking member 31 to re-lock with the first locking member 12, thereby fixing the angle of the support. After the angle is adjusted, the self-locking member 34 locks the first locking member 12, making it unable to move, thereby avoiding the phenomenon of the locking member jumping teeth and increasing stability; in addition, the angle can be adjusted by pressing the button 33, which is easy to operate.

[0043] Also refer to Figure 2 and Figure 6In one embodiment, the button 33 is pivoted to the movable seat 20 via the second rotating shaft 222, so that the first active portion 331 and the second active portion 332 can rotate around the second rotating shaft 222; the self-locking member 34 is pivoted to the movable seat 20 via the third rotating shaft 223, so that the second driven portion 341 and the first locking portion 342 can rotate around the third rotating shaft 223; the second locking member 31 is pivoted to the movable seat 20 via the fourth rotating shaft 314, so that the first driven portion 312 can rotate around the fourth rotating shaft 314. With this design, since the button 33, the self-locking member 34 and the second locking member 31 can rotate relative to the movable seat 20, the user can more simply and directly operate the button 33 to control the locking and unlocking states of the locking mechanism 30, thereby quickly adjusting the angle of the support; moreover, the pivot design ensures the stability and reliability of the button 33, the self-locking member 34 and the second locking member 31 during operation, reducing the possibility of operational failure due to structural looseness or misalignment; in addition, since each component can rotate quickly on its corresponding shaft, it can quickly respond to the user's operating instructions, and can achieve fast and accurate angle adjustment whether locking or unlocking; finally, the pivot design enables the various components to be compactly arranged on the movable seat 20, which not only saves space, but also makes the entire support structure more compact, which is convenient for installation and use.

[0044] In one embodiment, a circular arc surface is provided on the second active portion 332. As an example, see Figure 6 The second active part 332 is cylindrical. The second driven part 341 is provided with an inclined surface 341a (see Figure 2 ), when the button 33 is pressed, the arc surface slides along the inclined surface 341a, so that the first locking portion 342 rotates around the third rotating shaft 224 to release the lock of the second locking member 31. With this design, by means of the design of the arc surface and the inclined surface, when the button 33 is pressed, the user can easily unlock the second locking member 31 by sliding the arc surface along the inclined surface, thereby achieving rapid adjustment of the angle and simplifying the operation process.

[0045] In one embodiment, a limiting groove 341b is further provided in the middle of the second driven portion 341, and when the button 33 is in the natural state, the second active portion 332 is located in the limiting groove 341b to limit the rotation of the self-locking member 34. With this design, when the button 33 is in the natural state, the limiting groove 341b is designed to ensure the stable position of the self-locking member 34, and avoid the unintentional movement or rotation of the self-locking member 34 when there is no operation, thereby enhancing the stability and safety of the support.

[0046] In one embodiment, the first locking portion 342 is convex, and the second locking portion 313 is concave, and when the button 33 is in a natural state, the first locking portion 342 is inserted into the second locking portion 313. With this design, the convex-concave matching design enables the first locking portion 342 to be firmly inserted into the second locking portion 313, thereby providing a reliable mechanical lock for fixation and enhancing the stability and safety of the locking mechanism 30.

[0047] In one embodiment, the self-locking member 34 is approximately triangular in shape, with one corner pivotally connected to the movable seat 20 via the third rotating shaft 223, a second corner provided with a first locking portion 342, and a third corner provided with a second driven portion 341. With this design, the triangle is a stable geometric structure, and the triangular design of the self-locking member 34 helps to enhance the structural stability and anti-deformation ability of the entire locking mechanism 30, ensuring good working performance under different use conditions.

[0048] Also refer to Figure 2 , Figure 6 and Figure 7 In one embodiment, it further includes a first reset member 35 for resetting the self-locking member 34 when the button 33 is in a natural state.

[0049] In one embodiment, see Figure 2 , the first driven part 312 is a strip groove, and the first active part 331 is a cylinder, and the cylinder is inserted into the strip groove. With this design, the design of the strip groove and the cylinder simplifies the operation process of the button 33. The user only needs to press the button 33 to lock and unlock the locking mechanism 30, which improves the convenience of operation. Moreover, the geometrical coordination of the strip groove and the cylinder ensures the precise coordination between the first active part 331 and the first driven part 312, thereby ensuring the precise operation and reliable locking of the locking mechanism 30.

[0050] In one embodiment, the button 33 includes a rod 333 and a button 334. The rod 333 is located in the movable seat 20. The middle part of the rod 333 is pivoted to the movable seat 20 through the second rotating shaft 222. One end of the rod 333 is provided with a first active portion 331, and the other end is provided with a button 334. The button 334 is exposed from an opening on the movable seat 20. With this design, the rod 333 is pivoted to the movable seat 20 through the second rotating shaft 222. This structural design provides good mechanical support and stability, ensuring the stable operation of the button 33 and the reliable locking of the locking mechanism 30. Moreover, the rod 333 is located in the movable seat 20. This design helps to protect the internal mechanical structure and prevent the intrusion of dust and debris, thereby ensuring the long-term stable operation of the locking mechanism 30.

[0051] In one embodiment, a second restoring member 36 is further included, for restoring the button 33 when the button 33 is in a natural state.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
