Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more particularly to a bidirectionally lockable handle assembly and a stage lamp having the same. Background Art

[0002] In order to facilitate the movement of stage lights, designers usually set handles on the chassis or support arms. However, although the traditional one-piece molded handles are firm and stable, they often take up a lot of space during storage and storage, which is not conducive to the compact arrangement and transportation Therefore, designers began to develop foldable handles, hoping that the handles could be folded up when not in use to save space.

[0003] Because stage lights can be inverted during transportation or hung upside down on the truss when in use, existing folding handles only allow users to lift the stage light from one direction and cannot be lifted in the opposite direction, making it inconvenient to operate. Furthermore, some handles have a reset mechanism that keeps the handles converging, which can cause the user's hand to be pinched when lifting in the opposite direction, posing a safety hazard. Therefore, an improved folding handle design is urgently needed to increase the flexibility and convenience of the handle and facilitate the storage and transportation of stage lights. Utility Model Content

[0004] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a bidirectionally lockable handle assembly and a stage lamp having the same. By adding the rotating drive member, the locking plate can be easily switched between the first position and the second position, and the handle is locked. The user can lift the handle in both the forward and reverse directions to move the lamp.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a bidirectionally lockable handle assembly and a stage light having the same, wherein the bidirectionally lockable handle assembly includes a base plate; a handle, pivotally connected to the base plate, and a locking block is provided on the rotating shaft of the handle; at least one lock plate with an avoidance slot, slidably arranged on the base plate, the lock plate having a first position allowing the locking block to enter the avoidance slot, and a second position preventing the locking block from entering the avoidance slot; and also includes a rotary drive member for driving the lock plate to switch between the first position and the second position; wherein, when the lock plate is in the first position, the locking block can freely enter and exit the avoidance slot to allow the handle to rotate freely, and when the lock plate is in the second position, the handle is unfolded, the locking block abuts against the lock plate, and the lock plate restricts its forward rotation or reverse rotation.

[0006] The locking plate is driven to switch to the second position by the rotary drive member, and the locking plate blocks the rotational movement of the locking block, that is, the handle is bidirectionally locked and its rotation angle is limited, so that the user can lift and hold it in both forward and reverse directions; when the move is completed, it is only necessary to rotate the rotary drive member to switch the locking plate to the first position, so that the locking block enters the avoidance slot, that is, the handle is in a freely rotatable state, and finally the handle is switched to a convergent state.

[0007] Furthermore, the rotary drive member includes a rotating wheel having serrations on its outer periphery, and the locking plate includes serrations that engage with the rotating wheel. Rotating the rotating wheel allows the locking plate to switch between the first and second positions. The rotating wheel can directly or indirectly engage with the serrations of the locking plate, allowing the locking plate to be easily switched by simply rotating the rotating wheel. Using a serration structure for transmission is more convenient and provides excellent stability.

[0008] Furthermore, the handle is U-shaped, with the open ends of the handle pivotally connected to the base plate via a respective rotating shaft. Each rotating shaft is provided with a locking block, and the number of locking plates is two. The U-shaped structure of the handle improves grip comfort and ease of operation. Furthermore, two locking blocks and locking plates are provided at the open ends of the handle, respectively, so that the handle is evenly stressed after being locked, making it less susceptible to damage.

[0009] Furthermore, the rotary drive member includes a driven wheel meshing with the rotating wheel. The rotating wheel meshes with the serrated segment of one of the locking plates, and the driven wheel meshes with the serrated segment of the other locking plate. When the user rotates the rotating wheel, the driven wheel rotates in the opposite direction under the drive of the rotating wheel. At this time, the two locking plates on either side of the driving wheel can move simultaneously and in the same direction, making operation simple and convenient.

[0010] Furthermore, perpendicular to the handle's rotational axis, the rotating wheel and the driven wheel are arranged in an upper and lower arrangement, with the serrated segments of the two locking plates corresponding to the positions of the rotating wheel or driven wheel with which they engage. This creates a more compact and rational structural layout, effectively reducing the overall size of the handle assembly.

[0011] Furthermore, the invention further comprises a tension spring for maintaining the locking plate's tendency to move from the first position to the second position, wherein one end of the tension spring is fixedly connected to the base plate and the other end is connected to the locking plate. When the driving wheel releases the restriction on the locking plate, the tension spring pulls the locking plate to switch to the first position and maintains it, thereby locking the locking plate in place.

[0012] Furthermore, the handle is further configured to maintain its tendency to switch from extended to retracted, with one end of the torsion spring being fixed relative to the base plate and the other end being connected to the handle. When the driving wheel is rotated, the locking plate switches to the first position, the locking block enters the avoidance notch, and the handle switches to a retracted state driven by the torsion spring.

[0013] Furthermore, the base plate is provided with a through-hole corresponding to the escape notch. When the lock plate is in the first position, the escape notch and the through-hole are interlinked, and the locking block passes through the escape notch and enters the through-hole, or exits from the escape notch and the through-hole. With this arrangement, when the lock plate is in the first position, the escape notch and the through-hole combine to form a lock hole. The thickness of the lock hole is equal to the total thickness of the lock plate and the base plate. In this case, using a relatively thin lock plate allows the locking block to move in the escape notch without easily sliding out, allowing the lock plate to be stable in the first position or the second position, thereby increasing reliability.

[0014] Furthermore, the base plate is further provided with a guide post for guiding the lock plate to move in a straight line, and the lock plate is provided with a guide hole corresponding to the guide post, so that the movement of the lock plate is more precise and not easy to move.

[0015] Furthermore, the base plate has two bent plates on either side for pivotally connecting the handle, and further includes a limit plate fixedly connected to the bent plates. The locking block is located between the bent plates and the limit plate to maintain the locking block in a fixed position along the length of the handle's rotation axis. This arrangement prevents the handle from shifting during switching, allowing for smoother switching.

[0016] Furthermore, the locking block has a limiting protrusion and a locking protrusion. When the lock plate is in the first position, the locking protrusion can enter or exit the avoidance notch. When the lock plate is in the second position, the limiting protrusion and the locking protrusion are respectively blocked by the lock plate, restricting the locking block from rotating forward or reverse. The locking block utilizes the limiting protrusion and the locking protrusion to cooperate with the avoidance notch to achieve a locking function, resulting in a simple structure and material savings.

[0017] Furthermore, a locking plane is formed between the limiting protrusion and the locking protrusion. When the lock plate is in the second position, a gap is formed between the locking plane and the lock plate. After the locking block rotates forward or reversely by a certain angle, the limiting protrusion or the locking protrusion abuts against the lock plate, thereby keeping the handle unfolded. When the lock plate is in the second position, if the handle continues to rotate forward, the limiting protrusion abuts against the lock plate to achieve locking, preventing the handle from further rotation. In addition, if the handle rotates reversely, the locking protrusion abuts against the lock plate to achieve locking, thus providing a bidirectional locking function, allowing the user to hold the handle in both forward and reverse directions.

[0018] The present invention further provides a stage light comprising a lamp head for projecting a light beam, a support arm for pivotally connecting the lamp head, and a chassis for pivotally connecting the support arm, and further comprising a handle assembly as described in any of the foregoing items, the handle assembly being located on the support arm and / or the chassis. The handle assembly can be used to move the stage light in either a forward or reverse direction, without being restricted by the placement or installation angle of the stage light, thereby facilitating transportation and installation of the stage light.

[0019] Furthermore, the handle assembly is located on the support arm, and the support arm is provided with a receiving cavity, and when the handle is in a retracted state, the handle is accommodated in the receiving cavity. When the handle is fully retracted, the appearance of the support arm is more integrated, which is convenient for the placement and storage of the stage light.

[0020] Furthermore, the handle assembly is located on the support arm, which includes a support frame plate and a cover plate. The cover plate is buckled onto the support frame plate and forms a receiving cavity therewith. The base plate is located within the receiving cavity and is fixedly mounted on the support frame plate. The handle extends through the cover plate and can be retracted onto the surface of the cover plate, and the rotary drive member at least partially extends through the cover plate. Most of the handle assembly is housed within the receiving cavity, making it less susceptible to damage. At the same time, the handle and the rotary drive member extend through the cover plate, making it easier for the user to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate the embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will understand that some well-known structures and their descriptions may be omitted from the drawings. The positional relationships depicted in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0030] like Figures 1 to 4 As shown, a bidirectionally lockable handle assembly and a stage light having the same, wherein the bidirectionally lockable handle assembly includes a base plate 110; a handle 120, pivotally connected to the base plate 110, and having a locking block 122 on a rotation axis 121 of the handle 120; at least one locking plate 130 with an avoidance notch 131, slidably disposed on the base plate 110, the locking plate 130 having a first position allowing the locking block 122 to enter the avoidance notch 131, and a first position preventing the locking block 122 from entering the avoidance notch 131. 1; further comprising a rotary drive member 140 for driving the lock plate 130 to switch between the first position and the second position; wherein, when the lock plate 130 is in the first position, the locking block 122 can freely enter and exit the avoidance slot 131 to allow the handle 120 to rotate freely, and when the lock plate 130 is in the second position, the handle 120 is unfolded, the locking block 122 abuts against the lock plate 130, and the lock plate 130 restricts its forward rotation or reverse rotation.

[0031] The locking plate 130 is driven to switch to the second position by the rotary drive member 140, and the locking plate 130 blocks the rotational movement of the locking block 122, that is, the handle 120 is bidirectionally locked and its rotation angle is limited, so that the user can lift and hold it in both forward and reverse directions; when the move is completed, it is only necessary to rotate the rotary drive member 140 to switch the locking plate 130 to the first position, so that the locking block 122 enters the avoidance slot 131, that is, the handle 120 is in a freely rotatable state, and finally the handle 120 is switched to a convergent state.

[0032] Preferably, the locking block 122 has a locking protrusion 125 that can enter the avoidance groove 131, and the locking block 122 is provided with a curved surface 127 connected to the locking protrusion 125. When the locking plate 130 is switched to the first position, the handle 120 rotates from expansion to convergence. The setting of the curved surface 127 avoids the contact between the locking block 122 and the plate surface of the locking plate 130, thereby allowing the locking block 122 to rotate freely in the avoidance groove 131.

[0033] Preferably, the locking plate 130 is driven to move in a straight line by the rotary driving member 140 .

[0034] Preferably, the rotating shaft 121 is connected and fixed to the handle 120 by screws, which is convenient for installation. The locking block 122 and the rotating shaft 121 can be integrally formed as needed.

[0035] In a preferred embodiment of the present invention, the rotary drive member 140 includes a rotating wheel 141 having serrations on its outer periphery. The locking plate 130 includes a serrated segment 132 that can engage with the rotating wheel 141. Rotating the rotating wheel 141 allows the locking plate 130 to switch between the first and second positions. The rotating wheel 141 can directly or indirectly engage with the serrated segment 132 of the locking plate 130, allowing the position of the locking plate 130 to be easily switched by simply rotating the rotating wheel 141. Using a serrated structure for transmission is more convenient and provides good stability. Preferably, the rotating wheel 141 can directly or indirectly drive the movement of the locking plate 130 according to design requirements.

[0036] Preferably, the rotating wheel 141 is provided with a ridge 14 for user convenience.

[0037] In a preferred embodiment of the present invention, the handle 120 is U-shaped. The open ends 123 of the handle 120 are each pivotally connected to the base plate 110 via a respective rotational axis 121. Each rotational axis 121 is provided with a locking block 122, and there are two locking plates 130. The U-shaped structure of the handle 120 improves grip comfort and ease of operation. Furthermore, the two locking blocks 122 and locking plates 130, each corresponding to the open ends 123 of the handle 120, ensure even force on the handle 120 after locking, making it less susceptible to damage.

[0038] Preferably, the two locking plates 130 are symmetrically arranged on both sides of the base plate 110 , and the rotating wheel 141 is pivotally connected to the middle position of the base plate 110 .

[0039] In a preferred embodiment of the present invention, the rotary drive member 140 further includes a driven wheel 142 meshing with the rotating wheel 141. The rotating wheel 141 meshes with the serrated segment 132 of one of the locking plates 130, and the driven wheel 142 meshes with the serrated segment 132 of the other locking plate 130. When a user rotates the rotating wheel 141, the driven wheel 142 rotates in the opposite direction under the drive of the rotating wheel 141. At this time, the two locking plates 130 on either side of the driving wheel can move simultaneously and in the same direction, simplifying operation.

[0040] In a preferred embodiment of the present invention, the rotating wheel 141 and the driven wheel 142 are arranged in an upper and lower arrangement perpendicular to the rotation axis 121 of the handle 120. The serrated segments 132 of the two locking plates 130 are positioned to correspond to the positions of the rotating wheel 141 and the driven wheel 142 with which they engage. This results in a more compact and rational structural layout, effectively reducing the overall size of the handle assembly 100.

[0041] In a preferred embodiment of the present invention, a tension spring 150 is further included to maintain the locking plate 130's tendency to move from the first position to the second position. One end of the tension spring 150 is fixedly connected to the base plate 110, and the other end is connected to the locking plate 130. When the driving wheel releases its restraint on the locking plate 130, the tension spring 150 pulls the locking plate 130 to the first position and maintains it, thereby locking the locking plate 130. Preferably, both the base plate 110 and the locking plate 130 are provided with fixing posts 114 for the tension spring 150 to engage, facilitating installation.

[0042] In a preferred embodiment of the present invention, a torsion spring 160 is further included to maintain the handle 120 in a state of switching from extended to retracted. One end of the torsion spring 160 is fixed relative to the base plate 110, and the other end is connected to the handle 120. When the driving wheel is rotated, the lock plate 130 switches to the first position, the locking block 122 enters the avoidance notch 131, and the handle 120 switches to the retracted state under the drive of the torsion spring 160.

[0043] Preferably, the base plate 110 has bent plates 113 on both sides for pivotally connecting the handle 120, and further includes a limit plate 170 fixedly connected to the bent plate 113. The locking block 122 is located between the bent plate 113 and the limit plate 170 to keep the locking block 122 fixed in the longitudinal direction of the rotating shaft 121 of the handle 120. One end of the torsion spring 160 is fixed to the limit plate 170, and the other end passes through and is fixed to the rotating shaft 121.

[0044] When the external force of the rotary driving member 140 is lost, the locking block 122 is driven by the torsion spring 160 to abut against the inner wall of the avoidance slot 131 to push the locking plate 130 to move.

[0045] In a preferred embodiment of the present invention, the base plate 110 is provided with a through hole 111 corresponding to the escape notch 131. When the lock plate 130 is in the first position, the escape notch 131 and the through hole 111 are connected, and the locking block 122 passes through the escape notch 131 and enters the through hole 111 or exits from the escape notch 131 and the through hole 111. With this arrangement, when the lock plate 130 is in the first position, the escape notch 131 and the through hole 111 combine to form a locking hole, the thickness of which is equal to the total thickness of the lock plate 130 and the base plate 110. In this case, using a relatively thin lock plate 130 allows the locking block 122 to move in the escape notch 131 without sliding out, so that the lock plate 130 can be stably positioned in the first position or the second position, thereby achieving high reliability.

[0046] In a preferred embodiment of the present invention, the base plate 110 is further provided with a guide post 112 for guiding the lock plate 130 to move linearly, and the lock plate 130 is provided with a guide hole 133 corresponding to the guide post 112. This makes the movement of the lock plate 130 more precise and less likely to move.

[0047] Preferably, each of the locking plates 130 is provided with two guide holes 133 distributed along its movement direction, and the base plate 110 is provided with a guide column 112 corresponding to each guide hole 133, so that the movement of the locking plate 130 is more precise, less likely to move, and reduces jamming.

[0048] In a preferred embodiment of the present invention, the base plate 110 has bent plates 113 on both sides for pivotally connecting the handle 120, and further includes a limit plate 170 fixedly connected to the bent plates 113. The locking block 122 is located between the bent plates 113 and the limit plate 170, maintaining the locking block 122 in a fixed position along the length of the rotating shaft 121 of the handle 120. This arrangement prevents the handle 120 from shifting during switching, allowing for smoother switching.

[0049] Preferably, the limiting plate 170 is detachably mounted on the bending plate 113 by screws, so as to facilitate assembly and disassembly.

[0050] In a preferred embodiment of the present invention, the locking block 122 has a limiting protrusion 124 and a locking protrusion 125. When the lock plate 130 is in the first position, the locking protrusion 125 can enter or exit the avoidance notch 131. When the lock plate 130 is in the second position, the limiting protrusion 124 and the locking protrusion 125 are respectively blocked by the lock plate 130, restricting the locking block 122 from rotating forward or reverse. The locking block 122 achieves its locking function by utilizing the limiting protrusion 124 and the locking protrusion 125 to cooperate with the avoidance notch 131, resulting in a simple structure and material savings.

[0051] In a preferred embodiment of the present invention, a locking plane 126 is formed between the limiting protrusion 124 and the locking protrusion 125. When the locking plate 130 is in the second position, a gap is formed between the locking plane 126 and the locking plate 130. After the locking block 122 rotates forward or reversely by a certain angle, the limiting protrusion 124 or the locking protrusion 125 abuts against the locking plate 130, thereby keeping the handle 120 unfolded. When the locking plate 130 is in the second position, if the handle 120 continues to rotate forward, the limiting protrusion 124 abuts against the locking plate 130 to achieve locking, preventing the handle 120 from further rotation. In addition, if the handle 120 rotates reversely, the locking protrusion 125 abuts against the locking plate 130 to achieve locking, thus providing a bidirectional locking function, allowing the user to hold the handle 120 in both forward and reverse directions.

[0052] Preferably, by rotating the handle 120, the locking protrusion 125 and the limiting protrusion 124 are no longer in contact with the locking plate 130, and then the rotary drive member 140 is rotated to move the locking plate 130 to the first position. At this time, the locking protrusion 125 enters the avoidance groove 131, and finally unlocking is achieved.

[0053] like Figure 1 、 Figure 5 and Figure 6 As shown, in another embodiment, the present invention further provides a stage light, comprising a lamp head 200 for projecting a light beam, a support arm 300 for pivotally connecting the lamp head 200, and a chassis 400 for pivotally connecting the support arm 300, and further comprising the handle assembly 100 as described in any of the above items, the handle assembly 100 being located on the support arm 300 and / or the chassis 400. The handle assembly 100 can be used to move the stage light in either forward or reverse directions, without being restricted by the placement or installation angle of the stage light, thereby facilitating transportation and installation of the stage light.

[0054] In a preferred embodiment of the present invention, the handle assembly 100 is located on the support arm 300. The support arm 300 is provided with a receiving cavity 310. When the handle 120 is in a retracted state, it is accommodated in the receiving cavity 310. When the handle 120 is fully retracted, the appearance of the support arm 300 is more integrated, which facilitates the placement and storage of the stage light.

[0055] In a preferred embodiment of the present invention, the handle assembly 100 is located on the support arm 300. The support arm 300 includes a support frame 330 and a cover plate 320. The cover plate 320 is buckled onto the support frame 330 and forms a receiving cavity therewith. The base plate 110 is located within the receiving cavity and fixedly mounted on the support frame 330. The handle 120 extends through the cover plate 320 and can be retracted onto the surface of the cover plate 320. The rotary drive member 140 at least partially extends through the cover plate 320. The majority of the handle assembly 100 is housed within the receiving cavity, making it less susceptible to damage. At the same time, the handle 120 and the rotary drive member 140 extend through the cover plate 320, facilitating user operation.

[0056] Preferably, the cover plate 320 is provided with a receiving cavity 310 for accommodating the handle 120 .

[0057] In other embodiments of the present invention, the handle assembly 100 may also be disposed on two side surfaces of the chassis 400 , and the chassis 400 is provided with a receiving cavity 310 corresponding to the handle 120 .

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
