[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0033] The following is combined Figures 1 to 4 The specific embodiments of this utility model will be described in detail below.
[0034] This embodiment provides a universal adjustment bracket for the position of a light source, including a fixed plate 1, a lifting mechanism 2, a main support mechanism 3, and an auxiliary support mechanism 4.
[0035] The fixing plate 1 is used to fix the bracket to the installation position so as to fix the overall position of the bracket.
[0036] The lifting mechanism 2 includes a bottom frame 21, a top frame 22, a lifting drive component 23, and a side locking plate assembly 24. The bottom frame 21 is fixed to the fixed plate 1. The lifting drive component 23 connects the top frame 22 and the bottom frame 21. The side locking plate assembly 24 includes a strip plate 241 and a first fastener 242. The lower end of the strip plate 241 is fixed to the side wall of the bottom frame 21, and the upper part of the strip plate 241 has a vertically arranged sliding hole. The first fastener 242 passes through the sliding hole and is installed on the side wall of the top frame 22 to press the strip plate 241 against the side wall of the top frame 22. During operation, the first fastener 242 is first loosened, then the lifting drive component 23 drives the top frame 22 to rise and fall to a suitable height, and finally the first fastener 242 is tightened to fix the height of the top frame 22 relative to the bottom frame 21.
[0037] Specifically, the lifting drive component 23 in this embodiment includes a double scissor mechanism 231, connecting blocks 232, and adjusting bolts 233. The double scissor mechanism 231 consists of two sets of scissor assemblies. The extension and retraction direction of the scissor assemblies is vertical, and the two sets of scissor assemblies are parallel and opposite to each other. Each set of scissor assemblies is composed of two layers of scissor arms connected by two hinge shafts located on both sides. The upper and lower ends of the scissor assemblies are connected to the top frame 22 and the bottom frame 21, respectively. The connecting blocks 232 are connected between the two sets of scissor assemblies. There are two connecting blocks 232, each corresponding to one of the two hinge shafts. The adjusting bolts 233 pass through the two connecting blocks 232 and are used to adjust the distance between the two connecting blocks 232. During operation, manually tightening the nuts of the adjusting bolts 233 changes the distance between the two connecting blocks 232, thereby changing the height of the double scissor mechanism 231 and thus raising and lowering the top frame 22.
[0038] It is easy to understand that each layer of scissor arms includes two intersecting scissor bars, and the intersection of the two scissor bars is provided with a horizontally arranged pin, so that the two scissor bars can rotate around the pin; on both sides, that is, in the two directions along the width of the scissor arms, the two layers of scissor arms are connected by two hinge shafts located on both sides, that is, the top ends of the two scissor bars of the lower scissor arm are hinged to the bottom ends of the two scissor bars of the upper scissor arm through the horizontally arranged hinge shafts.
[0039] More specifically, in this embodiment, the bottom and top sides of the two sets of scissor lift assemblies are connected by two connecting shafts 234, with one connecting shaft 234 slidably connected to the bottom frame 21 or top frame 22, and the other connecting shaft 234 inserted into the bottom frame 21 or top frame 22. In detail, this embodiment has mounting strips 25 fixed inside both the bottom frame 21 and top frame 22. The mounting strips 25 have sliding windows; one connecting shaft 234 is placed within the sliding window to achieve a sliding connection, while the other connecting shaft 234 is inserted into the mounting strip 25. This unidirectional sliding structure ensures the definite relative position of the scissor lift assembly with the top frame 22 and bottom frame 21 in any state, thereby improving the stability of the device. To reduce sliding resistance, rollers can be fitted onto the slidably connected connecting shafts 234, so that the rollers contact the bottom frame 21 or top frame 22.
[0040] Specifically, the side locking plate assembly 24 in this embodiment is provided with at least two sets.
[0041] Specifically, the first fastener 242 is a bolt and nut pair. The bolt of the bolt and nut pair passes through the sliding hole and the side wall of the top frame 22. The strip plate 241 is pressed against the side wall of the top frame 22 by the nut and the head of the bolt of the bolt and nut pair.
[0042] The main support mechanism 3 includes a universal adjustable gimbal 31. The bottom end of the universal adjustable gimbal 31 is fixed on the top frame 22, and the top end of the universal adjustable gimbal 31 is fixedly connected to a mounting bracket 32 for mounting the laser source 100. The side wall of the universal adjustable gimbal 31 is screwed with a second fastener 33.
[0043] Specifically, in this embodiment, the mounting frame 32 is a U-shaped frame, and the web of the U-shaped frame is connected to the top of the universal adjustment gimbal 31 and the upper end of the telescopic cross shaft universal coupling 42. The wing plate of the U-shaped frame extends outward from the end away from the web plate to form a connecting plate 321, which is used to install the laser source 100.
[0044] Specifically, the first fastener 242 is a screw.
[0045] The auxiliary support mechanism 4 includes a damping turntable 41 and a telescopic universal joint 42. The damping turntable 41 is mounted on the top frame 22 with its axis arranged vertically. The lower end of the telescopic universal joint 42 is connected to the damping turntable 41, and the upper end of the telescopic universal joint 42 is connected to the mounting bracket 32. The telescopic universal joint 42 is equipped with a third fastener 43 for locking its length.
[0046] It is easy to understand that the damping turntable 41 is a rotating structure with built-in damping, capable of rotating 360° and hovering at any angle due to damping. The damping turntable 41 is a mature structure in this field and will not be described in detail here.
[0047] Specifically, the telescopic universal joint 42 of this embodiment includes a telescopic rod 421 and two universal joints 422 located at both ends of the telescopic rod 421. The lower universal joint 422 is connected to the damping turntable 41, and the upper universal joint 422 is connected to the mounting bracket 32.
[0048] More specifically, the telescopic rod 421 in this embodiment includes an outer cylinder 4211 and an inner rod 4212. The inner rod 4212 is slidably inserted into the outer cylinder 4211. The outer cylinder 4211 has a strip-shaped hole arranged along its length. A third fastener 43 passes through the strip-shaped hole and is installed on the inner rod 4212 to press the outer cylinder 4211 onto the inner rod 4212. In detail, the outer cylinder 4211 has two opposing strip-shaped holes. The third fastener 43 is a bolt and nut pair. The bolt of the bolt and nut pair passes through the strip-shaped hole and the inner rod 4212. The outer cylinder 4211 and the inner rod 4212 are pressed together by the nut and the head of the bolt of the bolt and nut pair.
[0049] Specifically, in this embodiment, the auxiliary support mechanism 4 is provided with at least three sets and is evenly distributed around the universal adjustment gimbal 31.
[0050] The working principle of the universal adjustment bracket for the light source position in this embodiment is as follows:
[0051] In use, the laser source 100 is fixedly installed on the mounting bracket 32. The laser source 100 is adjusted to a suitable height by the lifting drive component 23 and locked by the first fastener 242. The laser source 100 is adjusted to a suitable angle by the main support mechanism 3 and the auxiliary support mechanism 4 and locked by the second fastener 33 and the third fastener 43. This can adapt to the interface of various models.
[0052] The above are merely specific embodiments of this utility model, enabling those skilled in the art to understand or implement this utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
