Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 to 6, the invention discloses a video lamp, which includes a front-end housing 1, a thimble 2, a rotating shaft 3, a connecting rod 4 and an elastic limiting piece 5. The front end shell 1 is provided with a first opening 11 with the same direction as the light-emitting surface and a second opening 12 with the different direction from the light-emitting surface, the thimble 2 is telescopically arranged in the first opening 11, the rotating shaft 3 is arranged on the inner wall of the front end shell 1 and is positioned between the first opening 11 and the second opening 12, the connecting rod 4 is rotatably connected to the rotating shaft 3 and is arranged close to the inner wall of the front end shell 1, the first end 41 of the connecting rod 4 extends to the thimble 2, the second end 42 of the connecting rod 4 extends to the second opening 12, the elastic limiting part 5 is arranged on the rotating shaft 3, and the elastic force acts on the connecting rod 4. In the locked state, the first end 41 of the connecting rod 4 pushes the thimble 2 to partially protrude from the first opening 11 under the action of the elastic limiting member 5. In the unlocked state, the second end 42 of the link 4 is rotated relative to the rotating shaft 3 by an external force, so that the first end 41 of the link 4 is disengaged from the thimble 2.
The film and television lamp of the scheme has the advantages that the rotating shaft 3 is arranged on the inner wall of the front end shell 1 and is located between the first opening 11 and the second opening 12, the connecting rod 4 is rotatably connected to the rotating shaft 3 and is close to the inner wall of the front end shell 1, and the elastic limiting part 5 is arranged on the rotating shaft 3, namely the locking and unlocking structure is close to the inner wall of the front end shell 1. The rotation of the connecting rod 4 is converted into the linear motion of the thimble 2 to realize the locking and unlocking of the first opening 11, so that the problem of interference between a locking and unlocking structure of the headlamp optical equipment and a radiator is solved.
When a pushing force is applied to the second end 42 of the link 4 (the direction of the pushing force is the direction indicated by the arrow in fig. 3), the second end 42 of the link 4 drives the link 4 to rotate relative to the rotating shaft 3 under the pushing force, so that the first end 41 of the link 4 is separated from the thimble 2. When the pushing force applied to the second end 42 of the connecting rod 4 disappears, the connecting rod 4 rotates relative to the rotating shaft 3 under the action of the elastic limiting piece 5, so that the first end 41 of the connecting rod 4 pushes the thimble 2.
In some embodiments, the link 4 includes a first portion 43, an intermediate portion 44, and a second portion 45 connected in series. The first portion 43 is connected to one end of the intermediate portion 44, the second portion 45 is connected to the other end of the intermediate portion 44, the intermediate portion 44 is rotatably connected to the rotary shaft 3, the first end 41 is located at an end of the first portion 43, the second end 42 is located at an end of the second portion 45, the first end 41 has a lateral distance protruding the first portion 43, and the second end 42 has a lateral distance protruding the second portion 45. So arranged, the first end 41 has a lateral distance to project beyond the first portion 43 and the second end 42 has a lateral distance to project beyond the second portion 45, i.e. the link 4 is a curved rod, so that rotation of the link 4 is translated into linear movement of the thimble 2.
In some embodiments, the elastic limiting member 5 is a torsion spring, the elastic limiting member 5 includes a pressing portion 51 and two connecting portions 52 located at two ends of the pressing portion 51, the two connecting portions 52 are sleeved on the rotating shaft 3 and located at two sides of the middle portion 44, respectively, and the pressing portion 51 presses against the connecting rod 4 to provide an elastic torsion for the first end 41 of the connecting rod 4 to push the thimble 2. When an external force opposite to the direction of the elastic torsion is applied to the second end 42 of the connecting rod 4, the external force counteracts the elastic torsion of the torsion spring on the connecting rod 4, and the connecting rod 4 presses the pressing part 51 under the action of the external force to rotate towards the direction that the first end 41 of the rotating shaft 3 is far away from the thimble 2, so that the first end 41 of the connecting rod 4 is separated from the thimble 2. When the external force applied to the second end 42 of the connecting rod 4 disappears, the pressing part 51 presses the first end 41 of the connecting rod 4 under the action of the self elastic torsion, and the connecting rod 4 rotates relative to the rotating shaft 3 towards the direction that the first end 41 of the connecting rod 4 is close to the thimble 2 under the extrusion of the pressing part 51, so that the first end 41 of the connecting rod 4 pushes the thimble 2.
By adopting the design mode, on one hand, the two connecting parts 52 are arranged on the two sides of the connecting rod 4, which is beneficial to improving the stability of the elastic torsion provided by the torsion spring; on the other hand, since the pressing portion 51 abuts against the first end 41 of the link 4, the elastic torsion of the torsion spring can be directly transmitted to the first end 41 of the link 4, so that the effect of pushing the thimble 2 by the first end 41 of the link 4 is better.
It is understood that, in other preferred embodiments, the elastic limiting member 5 may also be a spring fixed on the front end housing 1, and a first end 41 of the spring abuts against the first end 41 of the link 4 to provide the link 4 with an elastic force that the first end 41 pushes the thimble 2, which is not limited herein.
In some embodiments, the movie lamp further comprises an elastic reset piece 6. The elastic reset element 6 is sleeved outside the thimble 2, and when the first end 41 of the connecting rod 4 is separated from the thimble 2, the elastic reset element 6 provides an elastic reset force for the thimble 2, so that the thimble 2 is retracted into the first opening 11. With such an arrangement, when the first opening 11 is in the unlocked state, the thimble 2 can return to the first opening 11 under the action of the elastic return element 6, so as to facilitate the installation of the optical accessory in the first opening 11 at the front end of the movie lamp.
It will be understood that in other preferred embodiments, it is also possible to adopt a design in which the movie lamp is not provided with the elastic return element 6, in which case, when the first opening 11 is in the unlocked state, the thimble 2 can be pushed back into the first opening 11 by an external force to mount the optical accessory, which is not limited at this time.
Further, in order that the elastic force applied to the thimble 2 by the elastic limiting member 5 via the connecting rod 4 can push the thimble 2 to partially protrude from the first opening 11 when the connecting rod 4 is not subjected to an external force, the elastic force of the elastic limiting member 5 is greater than the elastic force of the elastic restoring member 6.
When the connecting rod 4 is not subjected to an external force, the connecting rod 4 rotates relative to the rotating shaft 3 under the action of the elastic limiting part 5 until the first end 41 thereof pushes the ejector pin 2, the elastic force of the elastic limiting part 5 on the connecting rod 4 is transmitted to the elastic resetting part 6 through the ejector pin 2 so as to press the elastic resetting part 6 into a compression state, and the pushed part of the ejector pin 2 at the first end 41 of the connecting rod 4 protrudes out of the first opening 11, so that the locking of the first opening 11 is realized.
When a force larger than the elastic force of the elastic limiting member 5 is applied to the second end 42 of the connecting rod 4, the connecting rod 4 rotates relative to the rotating shaft 3 under the action of the external force until the first end 41 of the connecting rod is separated from the thimble 2, and the elastic resetting member 6 rebounds to drive the thimble 2 to move, so that part of the thimble 2 retracts into the first opening 11, and the unlocking of the first opening 11 is realized.
In some embodiments, the thimble 2 includes a pushing portion 21 and a main body portion 22 connected to the pushing portion 21. The pushing portion 21 is disposed toward the connecting rod 4, the main body 22 is telescopically inserted into the first opening 11, and the elastic restoring member 6 is sleeved on the main body 22 and abuts between the pushing portion 21 and the inner wall of the front-end housing 1. When the link 4 is not subjected to an external force, the first end 41 of the link 4 pushes the pushing portion 21, and the elastic restoring member 6 is in a compressed state. When the connecting rod 4 acts on the external force, the first end 41 of the connecting rod 4 is separated from the pushing part 21, and the elastic restoring member 6 pushes the pushing part 21 under the action of the self elastic force, so that the pushing part 21 drives the main body part 22 to retract into the first opening 11.
Further, the body portion 22 includes a head portion 221 and a tail portion 222. The head portion 221 is connected to the pushing portion 21 and the tail portion 222, the elastic restoring member 6 is sleeved on the head portion 221, the tail portion 222 is telescopically inserted into the first opening 11, a step is formed between the head portion 221 and the tail portion 222, the head portion 2212 includes a step surface 223 facing the front end housing 1, and the step surface 223 is used for limiting the axial telescopic position of the thimble 2. With this arrangement, in the process of converting the first opening 11 from the unlocking state to the locking state, the step surface 223 is attached to the inner wall of the front end housing 1 to limit the axial telescopic position of the thimble 2, which is beneficial to preventing the head 221 from protruding out of the first opening 11.
In some embodiments, in order to mount the rotating shaft 3 on the front housing 1, two mounting bases 13 having mounting grooves 131 are provided on the front housing 1. The two mounting bases 13 are arranged at intervals, the rotating shaft 3 is positioned between the two mounting bases 13, and two ends of the rotating shaft extend into the two mounting grooves 131 to be mounted on the two mounting bases 13, so that the rotating shaft 3 is mounted on the front-end shell 1.
Further, in order to fix the two ends of the rotating shaft 3 in the two mounting grooves 131, the two mounting bases 13 are both provided with first mounting holes 132, and the movie lamp further includes a fixing member 8. The fixing member 8 includes a front plate 82, two side plates 83 and two outer extension plates 84, the front plate 82 is connected to the two outer extension plates 84 through the two side plates 83, the front plate 82 and the two side plates 83 enclose an avoidance cavity 85 with a second opening 12 facing the rotating shaft 3, the two outer extension plates 84 are both provided with second mounting holes 81, and the two outer extension plates 84 respectively cover the mounting grooves 131 of the two mounting bases 13, so as to fix two ends of the rotating shaft 3 in the two mounting grooves 131.
In addition, since the fixing member 8 is formed with the avoiding cavity 85 with the second opening 12 facing the rotating shaft 3, the connecting rod 4 can rotate in the avoiding cavity 85 relative to the rotating shaft 3, thereby being beneficial to preventing the fixing member 8 from interfering with the rotation of the connecting rod 4.
In some embodiments, in order to prevent the thimble 2 from being separated from the first opening 11 by its own weight when the thimble 2 is retracted into the first opening 11, a limiting sleeve 14 is further disposed on the front end housing 1 for surrounding the first opening 11, and the limiting sleeve 14 is used for limiting the radial position of the thimble 2. So set up, carry on spacingly because of spacing sleeve 14 to the radial position of thimble 2 for thimble 2 can only move along the axis direction of first opening 11, thereby prevent that thimble 2 from breaking away from first opening 11 under the effect of self gravity.
Further, in order to prevent the link 4 from interfering with the link 4 when the link 4 rotates relative to the rotating shaft 3 to contact the thimble 2, the stopper sleeve 14 is provided with an escape notch 141 for escaping from the first end 41 of the link 4, and the first end 41 of the link 4 extends into the stopper sleeve 14 from the escape notch 141. With such an arrangement, the first end 41 of the connecting rod 4 can be limited by adopting a design mode that the first end 41 of the connecting rod 4 extends into the limiting sleeve 14 from the avoiding notch 141.
It is understood that in other preferred embodiments, the design mode without the relief notch 141 on the limiting sleeve 14 can also be adopted, in which case, the first end 41 of the connecting rod 4 needs to form a convex protrusion towards the hollow part of the limiting sleeve 14 so as to extend into the hollow part of the limiting sleeve 14 to press the thimble 2.
In some embodiments, a limiting member 15 is further disposed on the front end housing 1, and the limiting member 15 is disposed between the second opening 12 and the mounting base 13 for limiting the rotational position of the second end 42 of the connecting rod 4. So set up, because locating part 15 can carry on spacingly to the second end 42 of connecting rod 4 for the second end 42 of connecting rod 4 can rotate according to predetermined orbit, is favorable to improving the rotational stability of the second end 42 of connecting rod 4, prevents that the second end 42 of connecting rod 4 from taking place the skew under the exogenic action.
Specifically, the limiting member 15 is two limiting plates, the two limiting plates are arranged at an interval, and the second end 42 of the connecting rod 4 is located between the two limiting plates, so as to limit the rotating position of the second end 42 of the connecting rod 4.

Specifically, the push button 7 is partially exposed from the second opening 122 so as to be pushed by the user.
It is understood that a design method of directly applying the pushing force to the second end 42 of the link 4 without providing the push button 7 may also be adopted, which is not limited herein.
Further, a third mounting hole 71 is formed in the push button 7, a fourth mounting hole 421 is formed in the second end 42 of the connecting rod 47, and the fourth mounting hole 421 and the third mounting hole 71 are fixedly connected through a fastener, so that the push button 7 and the second end 42 of the connecting rod 4 are fixedly connected.
Furthermore, in order to facilitate the positioning and installation of the second end 42 of the connecting rod 47 and the push button 7, the push button 7 is provided with a plurality of positioning pillars 72, the plurality of positioning pillars 72 are disposed around the third mounting hole 71, and when the second end 42 of the connecting rod 47 is connected with the push button 7, the second end 42 of the connecting rod 47 is clamped between the plurality of positioning pillars 72, so as to realize the positioning of the second end 42 of the connecting rod 47 and the push button 7.
