Lamp with shifting type pivoting lock

Abstract

The utility model discloses a lamp with a toggle pivot lock, which comprises a lamp holder for emitting light, an arm for supporting the lamp holder to rotate and a case for supporting the arm to rotate, and the rotation of the lamp holder relative to the arm and / or the rotation of the arm relative to the case are / is locked through the toggle pivot lock. The shifting type pivot lock comprises a lock rod which is selectively matched with a lock position on the lock disc to limit rotation of the lock disc, the lock rod is driven by a horizontally-moving sliding plate to be close to the lock disc, and the included angle between the moving direction of the sliding plate and the moving direction of the lock rod is larger than zero. According to the lamp with the toggle type pivot lock, the sliding plate translates to drive the lock rod to move in the direction with the included angle larger than zero relative to the moving direction of the sliding plate, and therefore the lock rod is driven to be close to the lock disc to be matched with the lock position on the lock disc to limit rotation of the lock disc. Due to the fact that the sliding plate only translates instead of rotating like a lever, occupied space is small, and the sliding plate almost does not protrude out of the lamp, is not prone to damage and is more attractive.

Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a lighting fixture with a toggle-type pivot lock. Background Technology

[0002] Existing stage lights generally use lever-type pivot locks to restrict the rotation of the lamp head or arm. The lever moves around a circle, which takes up a lot of internal space in the stage light. The lever also extends a long distance outside the stage light, making it easy to break and unsightly. In addition, because it uses the lever principle, shortening the lever will make operation more laborious and inconvenient to use. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a lamp with a toggle-type pivot lock, which is easy and convenient to operate and occupies less space.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lamp with a toggle-type pivot lock, including a lamp head for emitting light, an arm supporting the rotation of the lamp head, and a housing supporting the rotation of the arm. The rotation of the lamp head relative to the arm and / or the rotation of the arm relative to the housing is locked by a toggle-type pivot lock. The toggle-type pivot lock includes a locking rod that selectively engages with a locking position on a locking disc to restrict the rotation of the locking disc. The locking rod is driven close to the locking disc by a translating slide plate, and the angle between the direction of movement of the slide plate and the direction of movement of the locking rod is greater than zero.

[0005] The lamp with a toggle-type pivot lock drives the locking rod to move at an angle greater than zero with the direction of movement of the sliding plate via the translational sliding plate. This drives the locking rod closer to the locking disc, where it engages with the locking position on the locking disc to restrict the rotation of the locking disc. Because the sliding plate only translates, rather than rotating like a lever, it occupies less space and hardly protrudes from the lamp, making it less prone to damage and more aesthetically pleasing.

[0006] Furthermore, it also includes a reset member that causes the locking lever to tend to move away from the locking disc. The reset member can slide in the opposite direction of the sliding plate, and when it stops pushing against the locking lever, it automatically drives the locking lever to move away from the locking disc, thereby releasing the locking of the locking disc.

[0007] Furthermore, the slide plate has a ramp extending along its translational direction on the side near the locking disc. The locking rod abuts against the ramp and is pushed closer to the locking disc by the ramp. Directly using the ramp to push the locking rod results in a simple structure and high stability.

[0008] Furthermore, the direction of movement of the sliding plate is perpendicular to the direction of movement of the locking lever. This allows the locking lever to move a greater distance while the sliding plate travels the same distance.

[0009] Furthermore, the sliding plate includes a supporting section and connecting sections at both ends of the supporting section. The ramp is located on the supporting section, and the supporting section is farther away from the locking disc than the connecting section. The fact that the supporting section is farther away from the locking disc than the connecting section allows space for the locking rod, with only the supporting section protruding, preventing the entire sliding plate from protruding from the light fixture.

[0010] Furthermore, the sliding plate is equipped with protective plates on both sides of the ramp to prevent the end of the locking rod from detaching from the ramp. These protective plates prevent the end of the locking rod from detaching from the ramp, thus improving the overall stability of the lever-type pivot lock.

[0011] Furthermore, the locking rod abuts against the ramp via rollers. The rollers effectively reduce the friction between the locking rod and the sliding plate, and reduce wear on the components.

[0012] Furthermore, the slide plate is slidably mounted on the sheet metal part of the arm, and an operating lever is connected to the side of the slide plate away from the locking rod. An extension hole is provided on the outer shell of the arm corresponding to the operating lever. The operating lever allows for more convenient application of force to the slide plate.

[0013] Furthermore, the slide plate is slidably mounted on the sheet metal part of the arm, and the sheet metal part of the arm is provided with guide posts. The slide plate is provided with an elongated guide hole corresponding to the guide posts. The elongated guide hole cooperates with the guide posts to prevent the slide plate from moving in the width direction of the guide hole, and the translation range of the slide plate is limited by the length of the guide hole.

[0014] Furthermore, the guide post includes a connecting seat protruding from the sheet metal part of the arm, and a guide section and a limiting piece fixed to the connecting seat and connected to each other. The guide section is located within the guide hole, and the connecting seat and the limiting piece together restrict the movement of the slide plate along the length direction of the guide section. The guide section and the limiting piece are integrated and designed separately from the connecting seat, which facilitates the installation of the slide plate, and the connecting seat and the limiting piece can prevent the slide plate from detaching from the guide section.

[0015] Furthermore, the locking disc is fixed to the lamp head, the toggle-type pivot lock is disposed on the arm, and the locking rod extends beyond the arm to selectively engage with the locking disc. The toggle-type pivot lock directly locks the lamp head, restricting its movement.

[0016] Furthermore, the drive motor for rotating the arm relative to the chassis is located inside the arm and connected to a driven wheel on the arm's pivot shaft via a timing belt. The pivot shaft of the arm is fixed relative to the chassis. The locking disc is integrated into the driven wheel, and a toggle-type pivot lock is disposed on the arm. The locking rod extends into the arm and selectively engages with the locking disc. The toggle-type pivot lock indirectly acts on the arm, restricting its movement, by locking the driven wheel.

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0023] like Figures 1 to 3This utility model provides a lamp with a toggle-type pivot lock, including a lamp head 110 for emitting light, an arm 120 supporting the rotation of the lamp head 110, and a housing 130 supporting the rotation of the arm 120. The rotation of the lamp head 110 relative to the arm 120 and / or the rotation of the arm 120 relative to the housing 130 is locked by a toggle-type pivot lock. The toggle-type pivot lock includes a locking rod 220 that selectively engages with a locking position 211 on a locking disc 210 to restrict the rotation of the locking disc 210. The locking rod 220 is driven close to the locking disc 210 by a translating slide plate 230. The angle between the direction of movement of the slide plate 230 and the direction of movement of the locking rod 220 is greater than zero.

[0024] The lamp with a toggle-type pivot lock drives the locking lever 220 to move at an angle greater than zero with the direction of movement of the sliding plate 230 via the translational sliding plate 230. This drives the locking lever 220 closer to the locking disc 210, where it engages with the locking position 211 on the locking disc 210 to restrict the rotation of the locking disc 210. Since the sliding plate 230 only translates and does not rotate like a lever, it occupies less space and hardly protrudes from the lamp, making it less prone to damage and more aesthetically pleasing.

[0025] Optionally, the locking disc 210 is fixed to the lamp head 110 / the arm 120 or its drive assembly / transmission assembly.

[0026] Optionally, the locking disc 210 is generally sheet-shaped or cylindrical, and the locking position 211 is generally a through hole or notch on the locking disc 210.

[0027] In a preferred embodiment of this invention, a reset member 240 is further included to cause the locking rod 220 to tend to move away from the locking disc 210. The reset member 240 can slide in the opposite direction of the sliding plate 230, and when it stops pushing against the locking rod 220, it automatically drives the locking rod 220 to move away from the locking disc 210, thereby releasing the locking of the locking disc 210.

[0028] Preferably, the reset member 240 is a spring, sleeved on the locking rod 220, and one end abuts against the protrusion on the locking rod 220.

[0029] In a preferred embodiment of this utility model, the sliding plate 230 has a ramp 233 extending along its own translational direction on the side near the locking disc 210. The locking rod 220 abuts against the ramp 233 and is pushed closer to the locking disc 210 by the ramp 233. Directly using the ramp 233 to push against the locking rod 220 results in a simple structure and high stability.

[0030] In this embodiment, the ramp 233 protrudes from the side surface of the slide plate 230 near the locking disc 210.

[0031] Preferably, recesses 234 are also connected to both ends of the ramp 233 so that when the locking rod 220 moves to both ends of the ramp 233, it is subjected to a certain holding force to prevent it from arbitrarily disengaging from the ends of the ramp 233.

[0032] In a preferred embodiment of this utility model, the sliding plate 230 includes a supporting section 231 and connecting sections 232 connected to both ends of the supporting section 231. The ramp 233 is located on the supporting section 231, and the supporting section 231 is farther away from the locking disc 210 than the connecting sections 232. The fact that the supporting section 231 is farther away from the locking disc 210 than the connecting sections 232 allows space for the locking rod 220, with only the supporting section 231 protruding, preventing the entire sliding plate 230 from protruding from the lamp.

[0033] In this embodiment, the supporting section 231 is parallel to the connecting section 232.

[0034] In a preferred embodiment of this utility model, the sliding plate 230 is provided with guard plates 235 on both sides of the ramp 233 to prevent the end of the locking rod 220 from detaching from the ramp 233. The guard plates 235 can prevent the end of the locking rod 220 from detaching from the ramp 233, thereby improving the overall stability of the toggle-type pivot lock.

[0035] In this embodiment, the height of the guard plate 235 relative to the ramp 233 is constant, thereby preventing the end of the locking bar 220 from detaching from the ramp 233 throughout the entire ramp 233.

[0036] In a preferred embodiment of this invention, the locking rod 220 abuts against the ramp 233 via a roller 221. The roller 221 can effectively reduce the friction between the locking rod 220 and the sliding plate 230, and reduce wear on the components.

[0037] In a preferred embodiment of this invention, the moving direction of the sliding plate 230 is perpendicular to the moving direction of the locking rod 220. This allows the locking rod 220 to move a greater distance while the sliding plate 230 moves the same distance.

[0038] Preferably, a clamping arm 222 is formed at one end of the locking rod 220 near the slide plate 230, and the two sides of the roller 221 are pivotally connected to the clamping arm 222.

[0039] In a preferred embodiment of this utility model, the slide plate 230 is slidably mounted on the sheet metal part 121 of the arm 120. An operating lever 236 is connected to the side of the slide plate 230 away from the locking rod 220. The outer shell 122 of the arm 120 has an extension hole 124 corresponding to the operating lever 236. The operating lever 236 allows for more convenient application of force to the slide plate 230.

[0040] In this embodiment, the operating lever 236 is plate-shaped and extends in a direction perpendicular to the sliding direction of the slide plate 230.

[0041] In a preferred embodiment of this utility model, the slide plate 230 is slidably disposed on the sheet metal part 121 of the arm 120. A guide post 123 is provided on the sheet metal part 121 of the arm 120, and the slide plate 230 is provided with an elongated guide hole 237 corresponding to the guide post 123. The elongated guide hole 237 cooperates with the guide post 123 to prevent the slide plate 230 from moving in the width direction of the guide hole 237, and the translational range of the slide plate 230 is limited by the length of the guide hole 237.

[0042] In this embodiment, the guide hole 237 is located on the connecting segment 232, and the guide hole 237 is provided on both connecting segments 232, and the two guide holes 237 have the same length direction.

[0043] In a preferred embodiment of this utility model, the guide post 123 includes a connecting seat 251 protruding from the sheet metal part 121 of the arm 120, and a guide section 252 and a limiting piece 253 fixed to the connecting seat 251 and connected to each other. The guide section 252 is located in the guide hole 237. The connecting seat 251 and the limiting piece 253 together restrict the sliding plate 230 from moving along the length direction of the guide section 252. The guide section 252 and the limiting piece 253 are connected as one piece and designed separately from the connecting seat 251, which facilitates the installation of the sliding plate 230. Furthermore, the connecting seat 251 and the limiting piece 253 can prevent the sliding plate 230 from detaching from the guide section 252.

[0044] In this embodiment, the guide segment 252 and the limiting piece 253 are both fixed to the connecting seat 251 by screws.

[0045] In this embodiment, the outer wall of the connecting seat 251 is connected to the sheet metal part 121 of the arm 120 by a plurality of reinforcing ribs.

[0046] In a preferred embodiment of this utility model, the locking disc 210 is fixed to the lamp head 110, the toggle-type pivot lock is disposed on the arm 120, and the locking rod 220 extends beyond the arm 120 and selectively engages with the locking disc 210. The toggle-type pivot lock directly locks the lamp head 110, restricting its movement.

[0047] In this embodiment, the locking disc 210 is plate-shaped, the locking positions 211 are arranged in a circle, and the center of the circle is located on the pivot axis of the lamp head 110.

[0048] In a preferred embodiment of this invention, the drive motor 310 for rotating the arm 120 relative to the housing 130 is located inside the arm 120 and is connected to the driven wheel 330 on the pivot shaft of the arm 120 via a timing belt 320. The pivot shaft of the arm 120 is fixed relative to the housing 130. The locking disc 210 is integrated into the driven wheel 330. The toggle-type pivot lock is disposed on the arm 120, and the locking rod 220 extends into the arm 120 and selectively engages with the locking disc 210. The toggle-type pivot lock indirectly acts on the arm 120 by locking the driven wheel 330, thereby restricting its movement.

[0049] In this embodiment, the locking disc 210 is cylindrical, and its center line coincides with the rotation axis of the driven wheel 330, and is disposed on the side of the driven wheel 330 near the chassis 130.
