DETAILED DESCRIPTION
[0020] The accompanying Figure 1 and the accompanying Figure 2The utility model provides a quick locking platform for stage lamp, which comprises a mounting plate one 10 for mounting the stage lamp, a mounting plate two 20 fixedly connected with the outside, and a rotating assembly 30 coaxially arranged between the mounting plate one 10 and the mounting plate two 20, wherein the rotating assembly 30 comprises a peripheral housing assembly 3 and an inner chuck assembly 4; the housing assembly 3 is fixedly connected with the mounting plate one 10, and the chuck assembly 4 is fixedly connected with the mounting plate two 20; the housing assembly 3 drives the mounting plate one 10 to rotate around the chuck assembly 4 by a certain angle under the action of external force.
[0021] The mounting plate one 10 is a circular plate, and six mounting holes are arranged in the middle of the mounting plate one 10 and uniformly distributed around the central axis, which are used for connecting with the rotating assembly 30; and the peripheral of the six mounting holes is provided with mounting holes for fixing the stage lamp.
[0022] The middle of the mounting plate two 20 is a circular plate, and the two sides of the mounting plate two 20 are rectangular plates; six mounting holes for locking the rotating assembly 30 are arranged on the circular plate of the mounting plate two 20 and uniformly distributed; and the two rectangular plates of the mounting plate two 20 are respectively provided with two mounting holes for connecting with the outside.
[0023] In order to facilitate installation, the housing assembly 3 comprises a circular ring-shaped housing one 31 and a circular ring-shaped housing two 32, and the housing two 32 is arranged above the housing one 31; the outer diameter of the housing one 31 is equal to the outer diameter of the housing two 32, and the height of the housing one 31 is higher than the height of the housing two 32; the housing one 31 and the housing two 32 are coaxially arranged with the mounting plate one 10, and the housing one 31 and the housing two 32 are locked on the mounting plate one 10 through the six mounting holes on the mounting plate one 10.
[0024] The rotating assembly 30 further comprises a mounting shaft arranged on the mounting plate two 20 and two bearings arranged on the mounting shaft; the two bearings are fixed on the mounting shaft through positioning nuts, and the housing assembly 3 is rotationally connected with the mounting shaft through the bearings; the upper surface of the mounting shaft is a circular plane, and a plurality of mounting holes for mounting the chuck assembly 4 are arranged on the upper surface of the mounting shaft in a radial direction; and a threaded hole coaxial with the central axis 100 is further arranged in the middle of the mounting shaft.
[0025] The chuck assembly 4 is arranged inside the housing assembly 3, and the chuck assembly 4 is located between the mounting plate one 10 and the mounting plate two 20; the chuck assembly 4 is arranged on the upper surface of the mounting shaft and is fixedly connected with the mounting plate two 20 through the mounting shaft.
[0026] The working state of the quick locking platform is that the housing assembly 3 stops rotating after rotating around the chuck assembly 4 by a certain angle under the action of external force; in the embodiment, the housing assembly 3 stops rotating by cooperating with the chuck assembly 4.
[0027] The advantage of this embodiment is that the stage lamp can be fixedly installed on the external member and can rotate 360°, and can rotate a specific angle as required.
[0028] As a new embodiment, the accompanying drawings Figure 2 and the accompanying drawings Figure 4 The connection between the shell assembly 3 and the chuck assembly 4 is gear engagement. In this embodiment, the operation of the quick-lock platform is as follows: the operator manually pulls the shell assembly 3 to apply an external force, so that the shell assembly 3 is disengaged from the chuck assembly 4 and starts to rotate. After the shell assembly 3 rotates to a predetermined angle, it will automatically re-engage with the chuck assembly 4. At the same time, the rotation of the shell assembly 3 will drive the stage lamp installed on the mounting plate 10 to rotate synchronously. If the shell assembly 3 needs to continue to rotate, an external force greater than the current clamping force needs to be applied on the quick-lock platform, and the shell assembly 3 will rotate again by a specific angle and re-engage with the chuck assembly 4 after rotation. In short, the quick-lock platform needs to be manually started to rotate and automatically re-engaged after rotation, thereby effectively preventing accidental rotation of the quick-lock platform when the stage lamp head is swinging. The advantage of this embodiment is that the shell assembly 3 will re-engage with the chuck assembly 4 without external force, ensuring that the quick-lock platform can be fixed when the stage lamp head is swinging, that is, no unintended rotation phenomenon occurs.
[0029] As a new embodiment, the accompanying drawings Figure 1 and the accompanying drawings Figure 2 The mounting plate 20 is also provided with a first scale 2 uniformly distributed around the central axis 100. The first scale 2 is uniformly distributed on the outer edge of the circular plate of the mounting plate 20, and the minimum interval of any one of the first scale 2 is the minimum scale. The minimum scale of the first scale 2 is 5°; the first scale 2 starts from 0° and increases to 90°, and then winds back from 90° to 0°, and so on, until the complete range of 360° is covered; the minimum rotation unit of the shell assembly 3 is equal to the minimum scale of the first scale 2, that is, the minimum rotation unit of the shell assembly 3 is 5°; the outer surface of the shell 31 is also provided with an arrow for pointing to the first scale 2, and after the shell assembly 3 rotates, the arrow can accurately point to the specific scale value on the first scale 2, so that the user can accurately read the current rotation angle of the stage lamp. The advantage of this embodiment is that the indication of the first scale 2 can make the user clearly know the current angle of the stage lamp, and the minimum rotation unit of the shell assembly 3 is equal to the minimum scale of the first scale 2, that is, no matter where the shell assembly 3 rotates, the user can clearly determine the rotation angle through the arrow, so that in actual application, the rotation angle of the stage lamp can be flexibly adjusted according to specific requirements.
[0030] As a new embodiment, the accompanying drawingsFigure 2 and the accompanying drawings Figure 3 The chuck assembly 4 comprises a circular flat chuck body 41, a plurality of polygonal flat movable claws 42 evenly distributed and elastically embedded in the outer edge of the chuck body 41, an elastic member I 43 between the chuck body 41 and the movable claws 42, an upper cover plate 44 closely attached to the upper surface of the chuck body 41, and a lower cover plate 45 closely attached to the lower surface of the chuck body 41. The outer end of the movable claw 42 is a toothed end 421 engaged with the shell assembly 3. The chuck body 41 is provided with a plurality of mounting holes arranged in a radial direction at equal intervals, and the chuck body 41 is locked on the mounting shaft through the mounting holes. The movable claw 42 is a polygonal flat plate composed of a triangular flat plate and a rectangular flat plate, and the top end of the triangular flat plate is the toothed end 421 of the movable claw. The toothed end 421 points to the shell assembly 3, and the other end of the movable claw 42 is connected with the elastic member I 43. The lower cover plate 45 is a circular ring flat plate, and the upper cover plate 44 is a circular flat plate. The upper cover plate 44 and the lower cover plate 45 are both provided with a plurality of mounting holes corresponding to the mounting holes of the chuck body 41, and the upper cover plate 44, the lower cover plate 45 and the chuck body 41 are all locked on the mounting shaft through the mounting holes thereon. The thickness of the movable claw 42 and the diameter of the elastic member I 43 are both smaller than the thickness of the chuck body 41, that is, the movable claw 42 and the elastic member I 43 are installed in the chuck body 41, and are limited by the upper cover plate 44 and the lower cover plate 45, so that the movable claw 42 and the elastic member I 43 will not exceed the upper surface and the lower surface of the chuck body 41, which is beneficial to the normal operation of the movable claw 42 and the elastic member I 43. In this embodiment, the elastic member I 43 is a spring, which is used to connect the movable claw 42 and the chuck body 41, so that the movable claw 42 can elastically move in the chuck body 41. The number of the movable claw 42 and the elastic member I 43 is both three, and they are evenly distributed in the chuck body 41. When the shell assembly 3 is disengaged from the toothed end 421 of the movable claw, the spring is compressed, and the toothed end 421 of the movable claw is close to the center axis. After the external force applied on the shell assembly 3 disappears, the spring is no longer compressed and returns to its original state, at the same time, the toothed end 421 of the movable claw returns to its original position and re-engages with the shell assembly 3. The beneficial effect of this embodiment is that the elastic member I 43 is beneficial to dynamically adjusting the position of the toothed end 421 of the movable claw, so as to accurately adjust various states between the shell assembly 3 and the movable claw 42, thereby continuously changing the rotation angle of the stage lamp.
[0031] As a new embodiment, the accompanying drawings Figure 3The chuck body 41 is provided with a plurality of uniformly distributed multi-stage grooves 411, the multi-stage grooves 411 include a limiting groove 4111 for accommodating the movable claw 42 and a mounting groove 4112 for mounting the elastic member 43, and the movable claw 42 is radially telescopic in the limiting groove 4111. The limiting groove 4111 is a polygonal groove body matched with the movable claw 42, and the mounting groove 4112 is a rectangular groove; the center of the limiting groove 4111 and the center of the mounting groove 4112 are located on the same circumferential radius passing through the center of the chuck body 41; one end of the elastic member 43 is connected with the mounting groove 4112, and the other end is connected with the movable claw 42; when the shell assembly 3 rotates, the toothed end 421 of the movable claw is always located at the outer edge of the chuck body 41; when the shell assembly 3 is stationary, the elastic member 43 is in a natural state, and the toothed end 421 of the movable claw extends out of the limiting groove 4111, at this time, the toothed end 421 of the movable claw is engaged with the shell assembly 3; when the shell assembly 3 rotates around the chuck assembly 4, due to the rotation extrusion of the shell assembly 3, the elastic member 43 is compressed, thereby driving the toothed end 421 of the movable claw to move towards the central shaft 100; after the shell assembly 3 stops rotating, the elastic member 43 returns to the natural state, the toothed end 421 of the movable claw extends towards the shell assembly 3, and re-engages with the shell assembly 3. The beneficial effect of this embodiment is that the movable claw 42 can radially telescope, which can make the shell assembly 3 rotate around the chuck assembly 4 out of engagement, which is conducive to adjusting the rotation angle of the stage lamp; and after stopping rotating, it can automatically extend and restore the engagement state with the shell assembly 3, preventing unnecessary rotation of the quick-lock platform for installing the stage lamp.
[0032] As a new embodiment, the chuck assembly 4 is combined with the shell assembly 3 to form a quick-lock platform, and the chuck assembly 4 is combined with the shell assembly 3 to form a quick-lock platform. Figure 2 The shell assembly 3 further comprises an internal gear 33, and the internal gear 33 is engaged with the toothed end 421 of the movable claw. The internal gear 33 is a circular ring plate, and the internal gear 33 is installed between the mounting plate 10 and the shell 32. The internal gear 33, the shell 31 and the shell 32 are all locked on the mounting plate 10, and the thickness of the internal gear 33 is consistent with the thickness of the movable claw 42. When the shell assembly 3 changes from a stationary state to a rotating state, the toothed end 421 of the movable claw changes from abutting the root of the gear tooth of the internal gear 33 to abutting the top of the gear tooth of the internal gear 33. Conversely, when the shell assembly 3 changes from a rotating state to a stationary state, the toothed end 421 of the movable claw changes from abutting the top of the gear tooth of the internal gear 33 to abutting the root of the gear tooth of the internal gear 33. Whether the shell assembly 3 is in a stationary state or a rotating state, the quick-lock platform is in an adjusting state at this time. The abutment of the toothed end 421 of the movable claw and the root of the gear tooth of the internal gear 33 is the engagement in the adjusting state. The beneficial effect of this embodiment is that the use of the internal gear 33 in cooperation with the movable claw 42 can achieve automatic clamping in the absence of external force, effectively preventing accidental rotation of the quick-lock platform.
[0033] As a new embodiment, in combination with the drawings, the rotating assembly 30 further comprises a positioning plate 5 installed above the upper cover plate 44, an elastic member two 6 vertically abutting against the positioning plate 5, and a positioning pin 7 for pressing the positioning plate 5, and the middle part of the chuck assembly 4 is provided with a through hole one 46 for avoiding the elastic member two 6.
[0034] The positioning plate 5 is a circular flat plate provided with a circular through hole in the middle part for avoiding the positioning pin 7, and the diameter of the circular through hole is smaller than the diameter of the elastic member two 6; one end of the elastic member two 6 abuts against the positioning plate 5, and the other end abuts against the mounting shaft through the through hole one 46; the lower end of the positioning pin 7 is provided with a thread, and the positioning pin is locked in the middle threaded hole of the mounting shaft through the thread connection. In this embodiment, there is also a locked state of the quick locking platform, and the locked state is that the shell assembly 3 cannot rotate around the chuck assembly 4 even under the action of external force, that is, the shell assembly 3 is in a fixed state.
[0035] Working principle of the locked state:
[0036] In the locked state, the positioning pin 7 is rotated downward in the threaded hole and presses the positioning plate 5 downward, at this time, the elastic member two 6 is compressed, the positioning plate 5 moves downward until it is tightly attached to the upper cover plate 44, because the positioning plate 5 reaches the locked position, the movable claw 42 and the internal gear 33 are in a locked state, that is, whether external force is applied on the mounting plate one 10 or the shell assembly 3, the top end of the movable claw 42 and the dedendum of the internal gear 33 always keep abutting against each other, and there is no relative movement between them.
[0037] Transition from the locked state to the adjustment state: the positioning pin 7 is rotated upward in the threaded hole and releases the positioning plate 5, at this time, the elastic member two 6 returns to the natural state, so that the positioning plate 5 returns to the original position; because the positioning plate 5 moves upward to return to the original position, the movable claw 42 and the internal gear 33 are out of the locked state; after the transition from the locked state to the adjustment state, the shell assembly 3 can rotate around the chuck assembly 4 under the action of external force and be engaged.
[0038] The beneficial effect of this embodiment is that the existence of the locked state can keep the shell assembly 3 and the chuck assembly 4 relatively stationary without being affected by the outside world when the operator does not apply external force.
[0039] As a new embodiment, in combination with the drawings, Figure 2The upper cover plate 44 is provided with a plurality of guide columns 441, and the positioning plate 5 is provided with a plurality of through holes two 51 for avoiding the guide columns 441, and the diameter of the through holes two 51 is greater than the diameter of the guide columns 441. The upper surface of the upper cover plate 44 is provided with three cylindrical guide columns 441 which are uniformly distributed, and the positioning plate 5 is provided with three circular through holes two 51 which are adapted to the guide columns 441; when the positioning plate 5 moves downward, the upper cover plate 44 remains stationary, and the guide columns 441 of the upper cover plate pass through the through holes two 51 of the positioning plate 5; therefore, only when the guide columns 441 and the through holes two 51 correspond to each other, the positioning pin 7 can smoothly spin and press the positioning plate 5, and the positioning plate 5 can move downward until it is tightly attached to the upper surface of the upper cover plate 44. The beneficial effect of this embodiment is that it is beneficial for the positioning plate 5 to smoothly move downward according to the predetermined position, and prevents the positioning plate 5 from deviating and causing the fast-lock platform to enter the locked state.
[0040] As a new embodiment, the accompanying drawings are combined Figure 2 The positioning plate 5 is provided with a plurality of clamping columns 52, and the movable claw 42 is provided with through holes three 422 which are adapted to the clamping columns 52. The lower surface of the positioning plate 5 is provided with three cylindrical clamping columns 52 which are uniformly distributed, and the number of the movable claws 42 is also three, and the middle part of each movable claw 42 is provided with a through hole three 422, and the upper cover plate 44 is also provided with a plurality of circular through holes which are uniformly distributed and are used for avoiding the clamping columns 52.
[0041] The locked state of the fast-lock platform is that the positioning plate 5 moves downward, the clamping columns 52 first pass through the circular through holes of the upper cover plate 44 until the positioning plate 5 is tightly attached to the upper cover plate 44, at this time, the clamping columns 52 are located in the through holes three 422 of the movable claws; the clamping columns 52 limit the radial expansion and contraction movement of the movable claws 42, that is, when the clamping columns 52 are located in the through holes three 422 of the movable claws, the movable claws 42 are still stationary under the influence of external force.
[0042] The beneficial effect of this embodiment is that the clamping columns 52 can be smoothly located in the through holes three 422, so that the fast-lock platform changes from the adjustment state to the locked state, that is, under the action of external force, the fast-lock platform also cannot rotate, which can effectively prevent the shell assembly 3 from rotating abnormally; for example, if a worker accidentally touches the shell assembly 3, the shell assembly 3 will not rotate.
[0043] As a new embodiment, the accompanying drawings are combined Figure 4The middle of the mounting plate 1 0 is further provided with a mounting groove 2 1 for accommodating the positioning plate 5 and the upper cover plate 44, and the inner diameter of the mounting groove 2 1 is greater than the outer diameter of the positioning plate 5 and the upper cover plate 44. The internal gear 33 is mounted on the lower surface of the mounting plate 1 0 and closely adheres to the lower surface of the mounting plate 1 0; the mounting height of the movable claw 42 and the chuck body 41 is consistent with the mounting height of the internal gear 33, and the upper cover plate 44 and the positioning plate 5 are higher than the upper surface of the internal gear 33, that is, the upper cover plate 44 and the positioning plate 5 are located inside the mounting groove 2 1 ; the side surface of the mounting groove 2 1 does not abut against the upper cover plate 44 and the positioning plate 5. The beneficial effect of this embodiment is that the space can be effectively saved, the installation of the components of the quick-lock platform is more compact, and the rotation of the shell assembly 3 around the chuck assembly 4 is facilitated.
