Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to an optical component replacement structure. Background Technology

[0002] LED stage lights feature a variety of optical components, such as lenses, prisms, and filters. Users typically use different optical components when operating a single LED stage light. Optical components can be switched electrically, but this requires a complex assembly structure. Alternatively, they can be switched manually, such as by using screws to secure them to the lamp housing. However, this requires tools and is inconvenient. Existing technology also uses clips to fix optical components to the lamp housing, but for large-format LED stage lights, these clips are prone to failure, leading to unstable connections. Utility Model Content

Each groove has a locking element, which includes a base, a pin, a first block, and a second block. The base is fixed to the groove and the pin is fixed to the base. The connectors of the first block and the second block are respectively sleeved on the pin. The locking heads of the first block and the second block each have locking surfaces that face each other. The locking surfaces are arc surfaces or angled surfaces. The locking heads of the first block and the second block each also include a support plate. A spring is provided between the support plate and the base.

[0006] An optical component is provided with at least one fastener, each fastener and each locking element are correspondingly provided, and the fastener can be inserted between the locking surface of the first block and the locking surface of the second block.

[0007] A further improvement is that the support plate is located on the side of the connector away from the connector surface.

[0008] A further improvement is that the support plate includes a through hole through which a fixing rod passes. The fixing rod also passes through the spring and is fixedly connected to the base. A limiting plate is provided at the end of the fixing rod away from the base. The cross-sectional area of ​​the limiting plate on the first surface is A, the cross-sectional area of ​​the through hole on the first surface is B, and the cross-sectional area of ​​the fixing rod on the first surface is C. A, B, and C satisfy the formula: A>B>C. The first surface is the XY plane.

[0009] A further improvement is that the fixing rod and the limiting plate are an integral structure, and the fixing rod is threadedly connected to the base.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] In the description of this utility model, the XY plane, XZ plane, and YZ plane are perpendicular to each other.

[0029] Reference Figure 1-4In one embodiment, an optical accessory replacement structure includes: a front cover 1, the front cover 1 having at least one recessed groove 101 along the height direction of the front cover 1, each groove 101 having a locking member 2, the locking member 2 including a base 201, a pin 202, a first block 203 and a second block 204, the base 201 being fixed to the groove 101, the pin 202 being fixed to the base 201, the connector of the first block 203 and the connector of the second block 204 being respectively sleeved on the pin 202, the locking member of the first block 203 and the locking member of the second block 204 respectively including a locking surface 205. Furthermore, the snap-fit ​​surfaces 205 of the two are arranged facing each other. The snap-fit ​​surfaces 205 are curved or angled surfaces. The snap-fit ​​connectors of the first block 203 and the second block 204 also include support plates 206. A spring 207 is provided between the support plate 206 and the base 201. The optical component 3 includes lenses, prisms, filters, etc. The optical component 3 is provided with at least one fastener 4. Each fastener 4 is correspondingly arranged with each snap-fit ​​2. The corresponding arrangement includes that the position and the number are mutually corresponding. The fastener 4 can be inserted between the snap-fit ​​surfaces 205 of the first block 203 and the second block 204. Manually insert the fastener 4 of the optical component 3 between the snap-fit ​​surfaces 205 of the first block 203 and the second block 204 in the front cover 1. During insertion, the first block 203 and the second block 204 rotate away from each other around the pin 202, compressing the spring 207. After insertion, release the manual button, and the spring 207 returns to its original shape. The snap-fit ​​joints of the first block 203 and the second block 204 abut against the fastener 4 to prevent the fastener 4 from detaching from the snap-fit ​​surfaces 205 of the first block 203 and the second block 204. Alternatively, the optical component 3 can be removed manually. This embodiment allows for quick replacement of the optical component 3. Since the locking connector of the first piece 203 and the locking connector of the second piece 204 each include a support plate 206, and a spring 207 is provided between the support plate 206 and the base 201, and the fastener 4 can be inserted between the locking surface 205 of the first piece 203 and the locking surface 205 of the second piece 204, the locking connectors of the first piece 203 and the second piece 204 can be used to abut against the fastener 4, increasing the abutment force, which is particularly suitable for large-scale LED stage lights.

[0030] Preferably, the connector and the support plate 206 are an integral structure, which facilitates molding.

[0031] In one embodiment, the support plate 206 is disposed on the side of the snap-fit ​​connector away from the snap-fit ​​surface 205, so that the spring 207 and the snap-fit ​​surface 205 are separated from each other, so as to avoid affecting the snap-fit ​​surface 205.

[0032] Continue to refer to Figure 4In one embodiment, the support plate 206 includes a through hole 208 through which a fixing rod 209 passes. The fixing rod 209 also passes through the spring 207 and is fixedly connected to the base 201. A limiting plate 210 is provided at the end of the fixing rod 209 away from the base 201. The cross-sectional area of ​​the limiting plate 210 on the first surface is A, the cross-sectional area of ​​the through hole 208 on the first surface is B, and the cross-sectional area of ​​the fixing rod 209 on the first surface is C. A, B, and C satisfy the formula: A>B>C. The first surface is an XY plane, which allows the first block 203 and the second block 204 to rotate normally about the pin 202 as the axis in a direction away from each other. It also allows the spring 207 to be normally compressed and deformed, while preventing the spring 207 from being over-compressed.

[0033] In one embodiment, the fixing rod 209 and the limiting plate 210 are an integral structure, and the fixing rod 209 is threadedly connected to the base 201, which facilitates the forming of the fixing rod 209.

[0034] In one embodiment, the curved surface is an inner curved surface, and the engaging surface 205 of the first block 203 and the engaging surface 205 of the second block 204 are concave to each other, such as... Figure 4 As shown; or, the arc surface is an outer arc surface, that is, the snap-fit ​​surface 205 of the first block 203 and the snap-fit ​​surface 205 of the second block 204 protrude.

[0035] In one embodiment, the angled surface includes two surfaces arranged at an angle of less than 180 degrees.

[0036] Reference Figure 3 and Figure 5 In one embodiment, the fastener 4 includes a top seat 401, a connecting part 402, and a contact part 403. The top seat 401 is fixedly connected to the optical component 3. The side of the top seat 401 facing the clip 2 is connected to the connecting part 402. The connecting part 402 is connected to the contact part 403, and the contact part 403 is circular on the second surface. The cross-sectional area of ​​the connecting part 402 on the second surface is smaller than the cross-sectional area of ​​the contact part 403 on the second surface. The second surface is an XZ plane, so that the contact part 403 can be inserted between the snap-fit ​​surface 205 of the first block 203 and the snap-fit ​​surface 205 of the second block 204.

[0037] In one embodiment, the front cover 1 and the lamp housing are detachably connected.
