Description

Technical Field

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

[0002] Stage lighting effectively enhances the stage performance effect, and stage lights are commonly used stage lighting equipment. Stage lights can focus the light source on a single focal point, thereby making the light source more concentrated or dispersed, forming single or multiple beams, thus creating a better stage lighting effect. During a stage performance, stage lights are arranged around the stage, with beams shining onto the stage in multiple directions to create stage lighting effects.

[0003] Currently, stage lights typically include a base, a lamp holder that can be rotatably mounted on the base, and a lamp head that can be swung on the lamp holder. The lamp head has a light-emitting lens mounted on its top, a lighting lamp inside, and several lighting effect modules arranged sequentially between the lighting lamp and the light-emitting lens to create different lighting effects. The light beam formed by the lighting lamp passes through the lighting effect modules and the light-emitting lens, and various lighting effects are created by changing different lighting effect modules.

[0004] However, existing stage lights lack a locking function for the lamp holder. When the lamp holder does not need to rotate and the light needs to form a light pattern at a specific angle, the lamp holder is easily rotated due to accidental contact by external force, causing the light pattern to deviate.

[0008] The main shaft is provided with a main gear and a locking disc connected to the bottom of the main gear; the edge of the locking disc extends out of the main gear and is provided with a number of locking holes at intervals on it, and the locking disc forms a locking position facing the locking plate. As the main shaft rotates, any locking hole will stay in the locking position.

[0009] The locking plate sequentially forms a swing arm section extending out of the base, a hinge section hinged to the base, a locking section corresponding to the locking position, and a positioning section corresponding to the support rod. The locking section is provided with a locking block that can engage with the locking port. The front end of the support rod is engaged with the positioning section, and the rear end of the support rod passes through the fixing plate. A spring is sleeved between the two ends of the support rod. The two ends of the spring abut against the front end of the support rod and the fixing plate, so that the spring provides the driving force for the support rod to support the locking plate. Under the support of the support rod, the locking plate pushes and pulls the swing arm section, which can drive the locking block of the locking section to swing in and out relative to the locking port of the locking position, so that the locking block engages with the locking port and locks the main shaft.

[0010] As a further technical solution of this utility model: the positioning section is recessed with a retaining opening, and the front end of the support rod is U-shaped, so that the front end of the support rod can be correspondingly engaged with the retaining opening.

[0011] As a further technical solution of this utility model: the locking plate and the support rod can be in a < or > shape relative to the locking position as the swing arm section is pushed and pulled.

[0012] As a further technical solution of this utility model: the base is provided on the other side with a self-rotation drive module for driving the main shaft to rotate; the self-rotation drive module includes a drive motor, a transmission gear and a transmission belt, the drive motor is installed in the base; the drive shaft of the drive motor extends to the bottom surface of the base, and the transmission gear is provided thereon; the transmission belt is sleeved on the transmission gear and the main gear.

[0013] As a further technical solution of this utility model: the lamp holder is provided with a housing at the front and rear ends of the base. Each housing is formed with a first housing surface covering the front or rear end of the base and a second housing surface covering one bottom end of the base. The second housing surface is provided with a through hole for the main shaft to pass through. The housing corresponding to the through direction of the swing arm section is provided with a swing limiting opening on the first housing surface, so that the swing arm section can pass through the swing limiting opening and the swing limiting opening limits the pushing and pulling range of the swing arm section.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model proposes a lamp holder locking structure for a stage lamp. Through the cooperation between the locking plate and the support rod, the locking plate, supported by the support rod, can swing in and out relative to the locking port located in the locking position, so as to lock the locking port with the locking block. In conjunction with the locking plate, the main shaft is locked, which effectively prevents the lamp holder from rotating accidentally under external force and ensures that the light pattern will not be deflected.

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figure 1 A lamp holder locking structure for a stage lamp is installed inside a lamp holder 10 of a stage lamp. It includes a locking plate 21 and a support rod 22. The lamp holder 10 has a base 11 and two seat arms 12 arranged opposite to each other on both sides of the base 11, allowing the lamp head to be rotatably positioned between the two seat arms 12. The base 11 is located above the base, and has a main shaft 111 formed at the center. On one side, there is a self-rotation drive module 112 for driving the main shaft 111 to rotate, and on the other side, the locking plate 21 and a fixing piece 113 are arranged one in front of the other at the bottom. The support rod 22 is arranged between the locking plate 21 and the fixing piece 113.

[0022] See also Figure 2 , Figure 3 The main shaft 111 is provided with a main gear 13 for cooperating with the self-rotation drive module 112 and a locking plate 14 connected to the bottom of the main gear 13, so that the self-rotation drive module 112 drives the main gear 13 and the locking plate 14 to rotate. The main shaft 111 rotates with the main gear 13, so that the lamp holder 10 rotates relative to the base.

[0023] The edge of the locking disc 14 extends out of the main gear 13, and a plurality of locking holes 141 are provided on it at intervals. The locking disc 14 forms a locking position 101 facing the locking plate 21. As the main shaft 111 rotates, any locking hole 141 will stay in the locking position 101.

[0024] Supported by the support rod 22, the locking plate 21 can swing in and out relative to the locking port 141 located in the locking position 101. The locking plate 21 sequentially forms a swing arm section 211 extending out of the base 11, a hinge section 212 hinged to the base 11, a locking section 213 corresponding to the locking position 101, and a positioning section 214 corresponding to the support rod 22. The locking section 213 is provided with a locking block 201 that can engage with the locking port 141. The front end of the support rod 22 is engaged with the positioning section 214. The rear end passes through the fixing plate 113, and a spring 202 is sleeved between the two ends of the support rod 22. The two ends of the spring 202 abut against the front end of the support rod 22 and the fixing plate 113, so that the spring 202 provides the driving force for the support rod 22 to support the locking plate 21. Under the support of the support rod 22, the swing arm section 211 is pushed and pulled, which can drive the locking block 201 of the locking section 213 to swing in and out relative to the locking port 141 located in the locking position 101. When the locking block 201 engages with the locking port 141, the locking plate 14 is locked.

[0025] Furthermore, in this embodiment, the locking block 201 and the locking section 213 are detachably connected by bolts.

[0026] Furthermore, in this embodiment, the positioning segment 214 is recessed with a retaining opening 203, and the front end of the support rod 22 is U-shaped, so that the front end of the support rod 22 can be correspondingly retained with the retaining opening 203.

[0027] Furthermore, in this embodiment, the locking plate 21 and the support rod 22 can be in a < or > shape relative to the locking position 101 as the swing arm section 211 pushes and pulls.

[0028] Furthermore, in this embodiment, in conjunction with reference to... Figure 4 The self-rotation drive module 112 includes a drive motor 31, a transmission gear 32, and a transmission belt 33. The drive motor 31 is installed inside the base 11. The drive shaft of the drive motor 31 extends to the bottom surface of the base 11, and the transmission gear 32 is provided thereon. The transmission belt 33 is sleeved on the transmission gear 32 and the main gear 13, so that the drive motor 31 can drive the main shaft 111 to rotate.

[0029] Furthermore, in this embodiment, in conjunction with reference to... Figure 5 The lamp holder 10 has a housing 41 at the front and rear ends of the base 11. Each housing 41 has a first housing surface 411 covering the front or rear end of the base 11 and a second housing surface 412 covering one bottom end of the base 11. The second housing surface 412 has a through-hole 401 for the main shaft 111 to pass through. The housing 41 corresponding to the direction of the swing arm section 211 to pass through has a limiting swing opening 402 on the first housing surface 411, so that the swing arm section 211 can pass through the limiting swing opening 402, and the limiting swing opening 402 limits the pushing and pulling range of the swing arm section 211.

[0030] Understandably, the method of using the lamp holder locking structure of this utility model is as follows: When the lamp holder 10 is not required to rotate, the swing arm section 211 is pushed and pulled, causing the locking plate 21 and the support rod 22 to swing accordingly, forming a < shape relative to the locking position 101. The locking block 201 is inserted into the locking port 141 located in the locking position 101 and engages with the locking port 141, thus locking the main shaft 111 in conjunction with the locking disc 14. When the lamp holder 10 needs to rotate, the swing arm section 211 is pushed and pulled in the other direction, causing the locking plate 21 and the support rod 22 to swing accordingly, forming a > shape relative to the locking position 101. The locking block 201, which is engaged with the locking port 141 of the locking position 101, is released, thus releasing the lock. In this way, the locking and unlocking of the lamp holder 10 is achieved.

[0031] In summary, the lamp holder locking structure of this utility model, through the cooperation between the locking plate 21 and the support rod 22, allows the locking plate 21 to swing in and out relative to the locking port 141 located in the locking position 101 under the support of the support rod 22. The locking plate 21 engages with the locking port 141 with the locking block 201, and together with the locking plate 14, locks the main shaft 111, effectively preventing the lamp holder 10 from rotating accidentally under external force and ensuring that the light pattern will not deviate.

[0032] Any combination of different embodiments of this utility model, provided it does not violate the inventive concept of this utility model, shall be considered as the disclosure of this utility model; any simple modifications to the technical solution and any combination of different embodiments within the scope of the inventive concept of this utility model, without violating the inventive concept of this utility model, shall be within the protection scope of this utility model.
