Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a damping locking structure. Background Technology

[0002] In the field of stage lighting technology, many connection structures require rotation with specific resistance. A common method to achieve this type of rotating structure with resistance is through screw locking. Using a single screw, the screw acts as both the shaft and provides axial locking force to the contact surface. However, if the rotation direction of the rotating arm is opposite to the locking direction of the screw, it will cause the screw to rotate in the opposite direction, loosening it and losing the axial locking force, leading to structural failure. Alternatively, using multiple screws (two or more) can solve the problem of a single screw, but the structure is more complex and difficult to miniaturize, especially unsuitable for compact designs. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a damping locking structure, which mainly solves the problems in the background art.

[0004] This utility model proposes a damping locking structure, including a knob, a fixed base, a damping plate, a rotating base, and a connector. The connector cooperates with the rotating base, the damping plate, the fixed base, and the knob respectively. The connector includes a limiting section, a rotating section, a square shaft section, and a screw section, all of which are integrally formed. The cross-sectional area of ​​the limiting section is larger than the through hole of the rotating base. The rotating section is located in the through hole of the rotating base. The rotating section or the square shaft section is located in the through hole of the damping plate. The square shaft section is also located in the square hole of the fixed base. The fixed base also includes a circular hole communicating with the square hole. The screw section passes through the circular hole and is threadedly engaged with the knob. The rotating base has a first toothed surface on the side facing the damping plate, and the fixed base has a second toothed surface on the side facing the damping plate.

[0005] A further improvement is that the first toothed surface includes a plurality of first tooth segments, which are distributed from the edge near the through hole toward the outer periphery of the rotating seat; the second toothed surface includes a plurality of second tooth segments, which are distributed from the edge near the square hole toward the outer periphery of the fixed seat.

[0006] A further improvement is that the cross-sectional shape of the tooth segment is trapezoidal.

[0007] A further improvement is that the outer periphery of the side wall of the knob is provided with a pattern, the shape of which includes stripes or arcs.

[0008] A further improvement is that the fixing seat is located on one side of the fixing arm and the two are an integral structure.

[0009] A further improvement is that the rotating seat is located on one side of the rotating arm and the two are an integral structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses a knob to press the first toothed surface of the rotating seat against the damping plate, which in turn presses against the second toothed surface of the fixed seat. The damping plate then generates friction with the first and second toothed surfaces respectively, and the knob is then tightened with the threaded section. By utilizing the fit between the square shaft section and the square shaft hole, the loosening of the rotating seat in the opposite direction to the tightening of the knob and the threaded section is reduced. The structure is simple and can be applied to compact stage lights. Attached Figure Description

[0026] Reference Figure 1-5 In one embodiment, a damping locking structure includes a knob 100, a fixed base 200, a damping plate 300, a rotating base 400, and a connector 500. The connector 500 engages with the rotating base 400, the damping plate 300, the fixed base 200, and the knob 100. The connector 500 includes an integrally formed limiting section 501, a rotating section 502, a square shaft section 503, and a screw section 504. The cross-sectional area of ​​the limiting section 501 is larger than the through hole 401 of the rotating base 400. This structure is designed to allow the first toothed surface 203 of the rotating base 400 to press against the damping plate 300 after the damping locking structure is installed. The damping plate 300 is also pressed against the second toothed surface 402 of the fixed seat 200. The rotating section 502 is located in the through hole 401 of the rotating seat 400. The rotating section 502 or the square shaft section 503 is located in the through hole of the damping plate 300. The square shaft section 503 is also located in the square hole 201 of the fixed seat 200. The fixed seat 200 also includes a round hole 202 communicating with the square hole 201. The screw section 504 passes through the round hole 202 and is threadedly engaged with the knob 100. The rotating seat 400 is provided with a first toothed surface 203 on the side facing the damping plate 300, and the fixed seat 200 is provided with a second toothed surface 402 on the side facing the damping plate 300. In this embodiment, pulling the knob 100 causes the first toothed surface 203 of the rotating seat 400 to press against the damping plate 300. The damping plate 300 also presses against the second toothed surface 402 of the fixed seat 200. Then, the damping plate 300 generates friction with the first toothed surface 203 and the second toothed surface 402 respectively. Then, the knob 100 is tightened with the threaded section. By utilizing the cooperation between the square shaft section 503 and the square shaft hole, the loosening of the rotating seat 400 in the opposite direction to the tightening of the knob 100 and the threaded section is reduced. The structure is simple and can be applied to compact stage lights.

[0027] In one embodiment, the knob 100 can be pulled manually; in other embodiments, the knob 100 can be pulled electrically.

[0028] Continue to refer to Figure 3 and Figure 4In one embodiment, the first toothed surface 203 includes a plurality of first tooth segments 204, which are distributed from the edge near the through hole 401 toward the outer periphery of the rotating seat 400; the second toothed surface 402 includes a plurality of second tooth segments 403, which are distributed from the edge near the square hole 201 toward the outer periphery of the fixed seat 200. The arrangement of the first toothed surface 203 and the second toothed surface 402 greatly improves the friction between the rotating seat 400 and the fixed seat 200.

[0029] Preferably, the cross-sectional shape of the tooth segment is trapezoidal.

[0030] In one embodiment, the outer periphery of the side wall of the knob 100 is provided with a pattern, the shape of which includes stripes, arcs or irregular shapes, to increase friction and facilitate pulling and tightening.

[0031] Continue to refer to Figure 1 and Figure 2 In one embodiment, the fixed seat 200 is disposed on one side of the fixed arm 11 and the two are integral structures, which facilitates the installation of the fixed seat 200 on the fixed arm 11. The rotating seat 400 is disposed on one side of the rotating arm 22 and the two are integral structures, which also facilitates the installation of the rotating seat 400 on the rotating arm 22.

[0032] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting the present invention. Clearly, the above embodiments of the present invention are merely examples to clearly illustrate the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
