Description

Technical Field

[0001] This application relates to the technical field of stage equipment, and in particular to a lamp holder structure for a stage lamp. Background Technology

[0002] Stage lights are lighting fixtures used to create stage lighting effects and are one of the means of stage art design.

[0003] Currently, Chinese utility model patent CN217635218U discloses an automatic focusing stage light, which includes a body with bases on all four sides of the bottom and handles on both sides. A display screen is located in one wall at the front of the body, and several adjustment buttons are located in the wall next to the display screen. A turntable is located in the top wall of the body, and a crank mechanism is mounted on the turntable. A lamp head is located within the crank mechanism. The lamp head is rotatably connected to the crank mechanism. During use, the lamp head emits light, and the angle of light emission is controlled by tilting the lamp head up and down.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: when the lamp body needs repair, in order to improve the quality of repair, it is necessary to stabilize the lamp body on one side to reduce the possibility of the lamp body shaking before the lamp body can be repaired on the other side, which is quite troublesome. Summary of the Invention

[0005] To facilitate the stability of the stage lamp body during maintenance, this application provides a lamp holder structure for a stage lamp.

[0006] This application provides a lamp holder structure for a stage lamp, employing the following technical solution:

[0007] A lamp holder structure for a stage lamp includes a lamp holder rotatably connected to a base. The lamp holder has a receiving groove for the lamp body to rotate up and down. A first rotating shaft and a second rotating shaft are provided on the outer periphery of the lamp body. The first rotating shaft and the second rotating shaft rotate on the groove wall of the receiving groove, respectively. The lamp holder has a mounting groove, and the first rotating shaft extends into the mounting groove.

[0008] The first rotating shaft has a mounting plate that rotates within the mounting groove on its outer periphery. The mounting plate has multiple slots on its periphery sidewall. The lamp holder is slidably connected to a mounting plate located within the mounting groove. The mounting plate has a locking plate. The lamp holder has a control component that controls the locking plate to engage with or disengage from the slots.

[0009] By adopting the above technical solution, when the lamp body needs maintenance, it is flipped to an angle that is convenient for maintenance. Then, the control component controls the movement of the mounting plate, so that the card plate is inserted into the card slot, restricting the rotation of the mounting plate. This controls the up and down flipping angle of the lamp body, making it easier to stabilize the lamp body during maintenance without having to hold it steady by hand.

[0010] Optionally, the control component includes a first control block and a second control block, which are respectively disposed on opposite sides of the mounting plate. The first control block, the second control block, and the mounting plate are distributed in a horizontal direction. The first control block and the second control block slide out of the lamp holder. When the first control block moves toward the second control block, the locking plate engages with the locking slot.

[0011] By adopting the above technical solution, when in use, pressing the first control block will cause the card plate to be inserted into the card slot, and pressing the second control block will help to cause the card plate to be disengaged from the card slot.

[0012] Optionally, the lamp holder is symmetrically provided with guide posts located in the mounting groove along the horizontal direction. The end of the guide post is threaded with a guide bolt. The mounting plate has a guide hole for the guide bolt to slide in the horizontal direction. An annular gasket is sleeved on the outer periphery of the guide bolt between the mounting plate and the guide post. The guide post is provided with a limiting element to restrict the sliding of the mounting plate along the length direction of the guide post.

[0013] By adopting the above technical solution, the guide bolt slides in the guide hole, which is beneficial for guiding the movement trajectory of the mounting plate.

[0014] Optionally, the limiting element is a wave-shaped gasket, which is sleeved on the outer periphery of the guide bolt and located between the annular gasket and the mounting plate.

[0015] By adopting the above technical solution, the wavy pad releases its elasticity, reducing the possibility of the mounting plate wobbling along the extension direction of the first rotation axis.

[0016] Optionally, the lamp holder is provided with an elastic pusher located within the mounting groove and pushing the mounting plate upward.

[0017] By adopting the above technical solution, the elastic pusher pushes the mounting plate upward, so that the guide bolt abuts against the wall of the guide hole, which helps to reduce the possibility of the mounting plate sliding up and down when it is not subjected to external force.

[0018] Optionally, the card plate has an arc-shaped surface structure on the side facing the mounting plate.

[0019] By adopting the above technical solution, it is easier to guide the card plate into the card slot.

[0020] Optionally, a limiting groove is provided in the lamp holder, the limiting groove is located on the side of the lamp body away from the mounting groove, the second rotating shaft extends into the limiting groove, a limiting plate is provided on the outer periphery of the second rotating shaft and located in the limiting groove, a limiting block is provided on the outer periphery of the limiting plate, and the lamp holder is provided with a stop block located in the limiting groove and corresponding to the limiting block. When the limiting block abuts against the stop block, it restricts the rotation of the limiting plate.

[0021] By adopting the above technical solution, the limiting plate is restricted from rotating when the limiting block abuts the stop block, reducing the possibility of mechanical damage caused by excessive rotation angle of the lamp body.

[0022] Optionally, the first control block is rotatably connected to the mounting plate. A drive column is slidably connected to the mounting plate on the side near the lamp body in a horizontal direction. A support column extending towards the card plate is provided on the outer periphery of the drive column. A connecting column extending horizontally towards the mounting plate is provided on the support column. A semi-circular straightening block is slidably connected to the connecting column on the side away from the support column. An elastic drive member pushing the straightening block towards the mounting plate is provided on the outer periphery of the connecting column. The first control block has a sliding groove for the drive column to slide in. A moving groove is spirally formed on the periphery of the sliding groove. Multiple moving blocks are spirally arranged on the outer periphery of the drive column. When the first control block rotates, it can drive the drive column to move towards the second control block. The lamp holder has a limiting block located on the side of the drive column away from the first control block. When the drive column abuts against the limiting block, the straightening block enters the card slot, and the mounting plate rotates into contact with the straightening block. When the first control block slides towards the second control block, the moving blocks slide unidirectionally with the first control block.

[0023] By adopting the above technical solution, rotating the first control block allows the correction block to be inserted into the slot, which facilitates the determination of the alignment between the card plate and the slot, reduces the difficulty of inserting the card plate into the slot, and reduces the possibility of mechanical damage to the first control shaft, mounting plate, and other parts inside the lamp holder caused by constantly pressing the first control block during the insertion process.

[0024] Optionally, the elastic driving component is a driving spring, which is sleeved on the outer periphery of the connecting post, with one end of the driving spring abutting against the straightening block and the other end abutting against the connecting post.

[0025] By adopting the above technical solution, the drive spring is released elastically, pushing the correction block to move towards the mounting plate.

[0026] Optionally, the corrective block has a connecting groove for the connecting post to slide in, and a positioning block is provided on the outer periphery of the connecting post. The groove wall of the connecting groove is connected to a positioning groove for the positioning block to slide in.

[0027] By adopting the above technical solution, the positioning block slides in the positioning groove, reducing the possibility of the straightening block detaching from the connecting column.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. During lamp body maintenance, the up-and-down tilting angle of the lamp body is controlled by inserting a clamp into the slot, which makes it easier to stabilize the lamp body during maintenance;

[0030] 2. By inserting the alignment block into the slot, the alignment of the card plate and the slot is confirmed, which facilitates the card plate being inserted into the slot and reduces the possibility of mechanical damage during the insertion process. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0043] This application discloses a lamp holder structure for a stage lamp.

[0044] Example 1

[0045] See Figure 1 The stage light's base structure includes a lamp holder 2 mounted on top of a base 1. The base 1 can be fixed to the ground with bolts or screws. The lamp holder 2 and base 1 are rotatably connected via a shaft. The base 1 is equipped with a drive motor to control the rotation of the lamp holder 2. A receiving groove 21 for accommodating the lamp body 3 is provided on the side of the lamp holder 2 away from the base 1. In use, the lamp body 3 emits light for stage design. Two rotating shafts are symmetrically fixed to the outer periphery of the lamp body 3. These shafts are rotatably connected to opposite sides of the receiving groove 21, allowing the lamp body 3 to be tilted up and down for angle adjustment.

[0046] See Figure 2 and Figure 3The lamp holder 2 has a vertically oriented mounting groove 24, which extends perpendicularly to the rotating shaft. The rotating shaft includes a first rotating shaft 22 and a second rotating shaft 23, with the first rotating shaft 22 extending into the mounting groove 24. A rotating gear 93 is fixedly connected to the outer periphery of the first rotating shaft 22, and the rotating gear 93 is located within the mounting groove 24. A power motor 9 is installed inside the lamp holder 2, and a transmission gear 91 is fixedly connected to the output shaft of the power motor 9. A transmission chain 92, connecting the transmission gear 91 and the rotating gear 93, is sleeved between the transmission gear 91 and the rotating gear 93. In use, the power motor 9 starts, driving the rotating gear 93 to rotate via the transmission chain 92, thereby rotating the first rotating shaft 22 and controlling the lamp body 3 to flip up and down.

[0047] See Figure 3 and Figure 4 The lamp holder 2 has a limiting groove 26 located on the side of the lamp body 3 away from the mounting groove 24. The second rotating shaft 23 extends into the limiting groove 26. A circular limiting plate 231 is fixedly connected to the outer periphery of the second rotating shaft 23, and an arc-shaped limiting block 232 is fixedly connected to the outer periphery of the limiting plate 231. A stop block 261 is fixedly connected to the lamp holder 2. The stop block 261 is located in the limiting groove 26 and close to the limiting plate 231, and the stop block 261 corresponds to the limiting block 232. When the lamp holder 2 is flipped up and down until the light-emitting side is close to the base 1, the limiting plate 231 rotates until the limiting block 232 abuts against the stop block 261. At this time, the lamp body 3 is restricted from continuing to rotate towards the base 1, which helps to reduce the possibility of mechanical damage caused by excessive rotation angle of the lamp body 3.

[0048] See Figure 3 and Figure 5 The first rotating shaft 22 (the first rotating shaft 22 in Figure 2 A mounting plate 221 is fixedly connected to the outer periphery of the lamp holder 2 (as indicated by the bidet). The mounting plate 221 is located on the side of the rotating gear 93 away from the lamp body 3. Two guide posts 6 are symmetrically fixed in the horizontal direction of the lamp holder 2, and the guide posts 6 are located in the mounting groove 24. The ends of the guide posts 6 are threaded with guide bolts 61. The mounting plate 25 has symmetrically opened guide holes 254. The width of the guide holes 254 is smaller than the diameter of the guide posts 6. The guide holes 254 extend in the horizontal direction, and the guide bolts 61 pass through the guide holes 254. When the mounting plate 25 slides, the guide bolts 61 slide into the guide holes 254, guiding the sliding trajectory of the mounting plate 25, so that the mounting plate 25 maintains a horizontal movement.

[0049] See Figure 3 and Figure 5An annular washer 62 is fitted around the outer periphery of the guide bolt 61, and the annular washer 62 is located on the side of the mounting plate 25 away from the lamp body 3. The guide bolt 61 is also provided with a limiting element, which is a corrugated washer 63, located between the annular washer 62 and the mounting plate 25. In use, the corrugated washer 63 releases its elastic force, which can keep the mounting plate 25 abutting against the guide post 6, which helps to reduce the distance of the mounting plate 25 along the first rotation axis 22 (the first rotation axis 22 is in Figure 2 (Marked) The possibility of swaying along the length direction.

[0050] See Figure 4 and Figure 5 The lamp holder 2 is equipped with an elastic pusher 5, which is a push spring. The push spring is installed in the mounting groove 24. One end of the push spring abuts against the bottom of the mounting plate 25 and is sleeved on the outer periphery of the fixing block 252, while the other end abuts against the lamp holder 2. In use, the push spring is released elastically, pushing the mounting plate 25 upward, reducing the possibility of the mounting plate 25 wobbling up and down. Furthermore, the push spring cooperates with the wave-shaped washer 63 to keep the mounting plate 25 stationary when it is not driven by an external force.

[0051] See Figure 3 and Figure 5 The mounting plate 221 has multiple slots 222 on its outer periphery. The lamp holder 2 is slidably mounted with a mounting plate 25 located within the mounting slot 24. The mounting plate 25 includes a fixing plate 251 and a fixing block 252. The fixing plate 251 is located at the top of the mounting plate 25 and away from the center of the mounting plate 25. The fixing block 252 is located at the bottom of the mounting plate 25 and is opposite to the fixing plate 251. A retaining plate 253 extending towards the mounting plate 221 is fixedly connected to the side of the fixing plate 251 away from the mounting plate 25. The retaining plate 253 extends horizontally and is connected to the first rotating shaft 22 (the first rotating shaft 22 is located at...). Figure 2 The central axis of the plate 253 is perpendicular to that of the fixed plate 251, and the side of the plate 253 away from the fixed plate 251 has an arc-shaped surface structure. When the lamp body 3 is flipped up and down, the corresponding area of ​​the plate 253 passing through the mounting plate 221 is the opening range of the slot 222.

[0052] See Figure 6 The lamp holder 2 is provided with a control component 4, which includes a first control block 41 and a second control block 42. The two sides of the mounting plate 25 are respectively provided with integrally formed connecting plates 43. The first control block 41 and the second control block 42 are respectively fixed on the two connecting plates 43. The opposite side walls of the lamp holder 2 are respectively provided with connecting holes for connecting mounting grooves 24. The first control block 41 and the second control block 42 pass through the connecting holes and protrude out of the lamp holder 2.

[0053] See Figure 4 and Figure 5When the lamp body 3 is flipped up and down to a certain angle, the mounting plate 25 rotates with the lamp body 3 until the slot 222 is aligned with the plate 253. Then, by pressing the first control block 41 towards the second control block 42, the mounting plate 25 is slid, causing the plate 253 to be inserted into the slot 222. At this time, the mounting plate 25 is restricted from rotating, and the up and down angle of the lamp body 3 is fixed. When it is necessary to release the restriction of the mounting plate 25, the second control block 42 is pressed towards the first control block 41. At this time, the mounting plate 25 moves the plate 253 away from the mounting plate 25 until the plate 253 is disengaged from the slot 222, allowing the mounting plate 25 to enter a state where it can rotate.

[0054] The implementation principle of the lamp holder structure for a stage lamp in Embodiment 1 of this application is as follows:

[0055] When the lamp body 3 is damaged and needs maintenance, flip the lamp body 3 up and down to a position that is easy to maintain. Then press the first control block 41 towards the second control block 42. When the locking plate 253 is aligned with the slot 222, the mounting plate 25 drives the locking plate 253 to move, so that the locking plate 253 is locked into the slot 222. At this time, the up and down angle of the lamp body 3 is fixed. When the locking plate 253 is not aligned with the slot 222, press the first control block 41 and the locking plate 253 abuts against the outer periphery of the mounting plate 25. Then keep pressing the first control block 41 and flip the lamp body 3 up and down again until the locking plate 253 is aligned with the slot 222. The locking plate 253 is locked into the slot 222, thus fixing the up and down angle of the lamp body 3.

[0056] Example 2

[0057] See Figure 6 and Figure 7 The difference between Embodiment 2 and Embodiment 1 is that the first control block 41 and the connecting plate 43 are rotatably connected. The mounting plate 25 is slidably connected to the drive column 7 in the horizontal direction on the side near the lamp body 3. The drive column 7 and the first control block 41 are on the same straight line, and the drive column 7 is slidably connected to the connecting plate 43.

[0058] See Figure 6 and Figure 8 A limiting block 232 is fixedly connected to the mounting plate 25 near the lamp body 3. A control groove is provided on the outer periphery of the drive column 7 along the axial direction. The limiting block 232 slides in the control groove and can limit the drive column 7 from entering the rotation state.

[0059] See Figure 7 and Figure 9A support column 71 extending upwards is fixedly connected to the outer periphery of the drive column 7. A connecting column 72 is fixedly connected to the side wall of the support column 71, away from the drive column 7. The connecting column 72 is perpendicular to the central axis of the first rotating shaft 22. A straightening block 73 is provided on the side of the connecting column 72 away from the support column 71. The straightening block 73 has a hemispherical block structure, with its arc-shaped convex side facing the mounting plate 25. The straightening block 73 has a connecting groove 731, in which the connecting column 72 slides. Two positioning blocks 721 are symmetrically fixed to the outer periphery of the connecting column 72. The groove walls of the connecting groove 731 are respectively connected to the positioning grooves 732. The positioning blocks 721 are slidably connected to the positioning grooves 732, reducing the possibility of the straightening block 73 disengaging from the connecting groove 731.

[0060] See Figure 7 and Figure 9 The connecting post 72 is equipped with an elastic driving element, which is a driving spring 8. The driving spring 8 is sleeved on the outer periphery of the connecting post 72, with one end abutting against the straightening block 73 and the other end abutting against the support post 71. In use, the driving spring 8 is released elastically, pushing the straightening block 73 towards the mounting plate 25, so that the positioning block 721 remains in abutting against the positioning groove 732 on the side away from the mounting plate 25.

[0061] See Figure 8 and Figure 10 The first control block 41 has a sliding groove 411 on the side near the drive column 7, and the support column 71 (the support column 71 is in Figure 7 (The marked block) slides within the slide groove 411. The peripheral wall of the slide groove 411 has a moving groove 412 extending in a spiral direction. Multiple moving blocks 74 are fixed to the outer periphery of the support column 71 in a spiral direction. The moving blocks 74 are located within the slide groove 411 and slide within the moving groove 412. The moving blocks 74 are right-angled triangular blocks, with their inclined surfaces facing away from the second control block 42. The moving blocks 74 are made of a material with a certain elasticity, such as plastic. The lamp holder 2 is provided with a limiting block 75, which extends towards the mounting plate 25 and is located on the side of the drive column 7 away from the first control block 41.

[0062] The implementation principle of the lamp holder structure for a stage lamp in Embodiment 2 of this application is as follows:

[0063] In the initial state, the drive column 7 is away from the limiting block 75, and the distance between the side of the straightening block 73 away from the support column 71 and the mounting plate 25 is equal to the distance between the side of the clamping plate 253 away from the fixing plate 251 and the mounting plate 25. The guide bolt 61 abuts against the wall of the guide hole 254 away from the first control block 41. When the lamp body 3 needs maintenance, the first control block 41 is rotated forward. At this time, the moving block 74 slides in the moving groove 412, causing the drive column 7 to move towards the limiting block 75 until it abuts against the limiting block 75 and stops. If the straightening block 73 is aligned with the clamping groove 222, the straightening block 73 will engage in the clamping groove 222. If the straightening block 73 is not aligned with the clamping groove 222, the straightening block 73 will abut against the outer periphery of the mounting plate 25, and the drive spring 8 will enter a compressed state. Then rotate the lamp body 3 until it stops at an angle that is convenient for maintenance. When the lamp body 3 rotates, the mounting plate 25 rotates accordingly. When the straightening block 73 is aligned with the slot 222, the drive spring 8 pushes the straightening block 73 into the slot 222. When the slot 222 and the straightening block 73 gradually become misaligned, the mounting plate 25 and the straightening block 73 slide together, pushing the straightening block 73 away from the slot 222. At this time, the alignment of the mounting plate 253 and the slot 222 can be judged according to the amount of force required when the lamp body 3 rotates. When the correcting block 73 is engaged in the slot 222, the mounting plate 253 and the slot 222 are aligned. At this point, the first control block 41 can be pressed to slide the mounting plate 25, causing the mounting plate 253 to engage in the slot 222, thus restricting the mounting plate 25 and maintaining the vertical angle of the lamp body 3. During the sliding of the mounting plate 25, the first control block 41 and the moving block 74 slide in one direction, allowing the drive column 7 and the mounting plate 25 to slide relative to each other until the positional relationship between the correcting block 73 and the mounting plate 253 returns to its initial state. The entire process is simple. When controlling the vertical angle of the lamp body 3, it is not necessary to keep the first control block 41 pressed, which greatly reduces the possibility that the first control block 41 will move the mounting plate 25 under the action of inertia when the mounting plate 253 is aligned with the slot 222, causing the mounting plate 253 to engage rapidly in the slot 222. This helps to reduce the possibility of mechanical damage when the mounting plate 253 engages in the slot 222.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
