Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a button type locking structure and a stage lamp having the same. Background Art

[0002] Most stage lights have a lamp head that generates a light beam, an arm for pivoting the lamp head, and a chassis for controlling the entire lamp. A pivot axis is set between the lamp head and the arm, and between the arm and the lamp head. When the lamp is not in working condition and loses the driving force of the motor, the lamp head can rotate freely relative to the arm, and the arm can rotate freely relative to the chassis, which is inconvenient for maintenance and even easy to cause collision during transportation. At this time, it is necessary to set a vertical lock and a horizontal lock on the arm to fix the rotation angle of the lamp head and the arm.

[0003] Common locking structures in stage lights include knob-type, paddle-type, or directly holding the pivot shaft by a locking member, using friction to limit the rotation of the pivot shaft. The knob-type lock achieves locking through the lock disk located on the pivot shaft and the lock core extending from the arm housing. After pulling out the lock core engaged with the lock disk and rotating it 90 degrees, the unlocked state is maintained by limiting the knob handle. Conversely, locking is achieved by rotating the lock core and resetting the lock core to reengage the lock disk through the elastic force of the compression spring. However, due to the limited installation space of the arm and the small knob handle, the operation is inconvenient; the paddle lock is opened and closed by moving the paddle into and out of the position and pulling the spring. The structure is complex, and it takes a lot of effort to unlock and unlock, and it is not beautiful. Moreover, these locking structures are too exposed to the lamp housing, which makes the integrity of the entire lamp housing lack. Utility Model Content

[0004] The utility model overcomes at least one defect of the prior art and provides a button-type locking structure and a stage light having the same. The locking or unlocking state of the arm can be switched by a button-type method, and the operation is simple.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a button-type locking structure and a stage light having the same, wherein a button-type locking structure comprises a lock shaft with a supporting column arranged at one end, a first mounting plate and a second mounting plate arranged oppositely, and a lock disk, the lock shaft is circumferentially provided with a guide protrusion, the lock shaft is inserted in the first mounting plate, and the supporting column can directly or indirectly act on the lock disk after passing through the second mounting plate; an annular protrusion and a limiting protrusion having at least one group of first concave positions and second concave positions are respectively arranged on the side where the first mounting plate and the second mounting plate are close to each other, the annular protrusion and the limiting protrusion cooperate to form a guide groove for limiting the movement direction of the guide protrusion, and also comprises an elastic member for forcing the guide protrusion to move along the guide groove; pressing the lock shaft causes the guide protrusion to move from the second concave position to the first concave position, the supporting column directly or indirectly acts on the lock disk to lock it, and when the lock shaft is pressed again, the guide protrusion moves to the second concave position under the action of the elastic member, and the supporting column unlocks the lock disk.

[0006] When the lock shaft is pressed, driven by the lock shaft, the guide protrusion is pressed toward the limit protrusion and moves along its edge. When the lock shaft loses pressure, the elastic member acts on the lock shaft, and the guide protrusion is pushed toward the annular protrusion and moves along the edge, and finally stops at the first concave position or the second concave position. At the same time, the lock shaft will also rotate around its axial direction by a certain angle. The locking or unlocking state can be easily switched by pressing. The overall structure of the locking structure is simple, occupies a small space, is easy to maintain, and has strong versatility.

[0007] Furthermore, the annular protrusion and the limiting protrusion edge are provided with two groups of the first concave positions and the second concave positions, and the first concave positions and the second concave positions are provided adjacent to each other. The locking state or the unlocking state can be switched by pressing the lock shaft to rotate it 90 degrees around its axis, thereby preventing the protrusion from traveling too long in the guide groove during a single switching process.

[0008] Furthermore, it also includes a pressing piece rotatably connected to the end of the lock shaft away from the lock disk. The pressing piece is provided to further facilitate the operator to press the lock shaft.

[0009] Furthermore, the end of the pressing member close to the lock shaft is recessed with a receiving groove for receiving the end of the lock shaft, and the end of the lock shaft is clamped in the receiving groove through a bearing. Such a configuration allows the lock shaft to rotate relative to the pressing member, and the configuration of the receiving groove makes the locking structure more compact.

[0010] Furthermore, a threaded hole is provided at one end of the lock shaft close to the pressing piece, and the nut of the screw connected with the threaded hole abuts against the inner ring edge of the bearing, so that the connection between the three is more secure, and the gap between the bearing, the pressing piece or the lock shaft is prevented from falling off due to long-term use.

[0011] Furthermore, it also includes a limit rod that is arranged perpendicular to the length direction of the lock shaft and is arranged at one end of the lock shaft away from the abutting column, and both ends of the limit rod protrude from the lock shaft body and form the guide protrusion. Because the guide protrusion always rubs against the annular protrusion or the limit protrusion during the movement of the guide groove, it is easy to cause wear. By adopting a detachable combination, the guide rod can be replaced in time after being worn, so that the locking structure can always maintain accurate locking.

[0012] Furthermore, the edge of the lock plate is circumferentially provided with a plurality of lock holes or locking notches that can be engaged with the abutting pillars. The structure is simple and easy to process, and the engaging and engaging method is accurate and convenient.

[0013] Furthermore, the elastic member is a tower spring, and further includes a mounting bracket for mounting the tower spring, the abutting column passes through the third through hole of the mounting bracket and directly acts on the lock plate, one end of the tower spring abuts the lock shaft, and the other end abuts the mounting bracket. When the lock shaft is pressed, the tower spring is compressed, and when the pressure acting on the lock shaft disappears, the tower spring recovers its deformation, abuts the lock shaft and acts on the guide protrusion, causing it to move along the edge of the annular protrusion, thereby repeatedly switching the guide protrusion between the first concave position and the second concave position.

[0014] Furthermore, it also includes a locking bracket with one end against the abutting column, and the locking bracket is rotatably connected to the second mounting plate through a mounting seat; the elastic member is a tension spring, one end of the tension spring is connected to the end of the locking bracket close to the abutting column, and the other end is connected to the second mounting plate, and the end of the locking bracket away from the abutting column is provided with a locking piece that can be locked with the lock disk. By providing the locking bracket, the locking force direction of the locking structure is changed. When the lock disk is arranged parallel to the direction of the lock shaft, the locking structure of the utility model can also be used for locking, which has strong versatility.

[0015] The utility model also provides a stage lamp, comprising a lamp head, an arm, a chassis and any of the aforementioned locking structures, wherein a pivot shaft is provided between the chassis and the arm and / or between the arm and the lamp head, the lock plate is fixedly connected to the pivot shaft, and the locking structure can selectively limit the rotation angle of the pivot shaft. By adopting the locking structure described in the utility model, only a hole for the operator to press the lock shaft is required to switch the locking or unlocking state of the pivot shaft, making the lamp more integrated and more beautiful.

DETAILED DESCRIPTION

[0028] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0029] like Figures 1 to 3 As shown, a button-type locking structure and a stage light having the same, wherein a button-type locking structure comprises a lock shaft 100 with a supporting column 110 at one end, a first mounting plate 200 and a second mounting plate 300 arranged opposite to each other, and a lock plate 400, wherein the lock shaft 100 is circumferentially provided with a guide protrusion 120, the lock shaft 100 is inserted into the first mounting plate 200, and the supporting column 110 can directly or indirectly act on the lock plate 400 after passing through the second mounting plate 300; an annular protrusion having at least one set of first concave position 610 and second concave position 620 is respectively provided on one side of the first mounting plate 200 and the second mounting plate 300 close to each other. The guide protrusion 120 and the limiting protrusion 230 cooperate to form a guide groove 250 that limits the movement direction of the guide protrusion 120, and also include an elastic member that forces the guide protrusion 120 to move along the guide groove 250; the lock shaft 100 is pressed to make the guide protrusion 120 move from the second recessed position 620 to the first recessed position 610, and the supporting column 110 directly or indirectly acts on the lock disk 400 to lock it. When the lock shaft 100 is pressed again, the guide protrusion 120 moves to the second recessed position 620 under the action of the elastic member, and the supporting column 110 unlocks the lock disk 400.

[0030] When the lock shaft 100 is pressed, driven by the lock shaft 100, the guide protrusion 120 is pressed toward the limit protrusion 230 and moves along its edge. When the lock shaft 100 loses pressure, the elastic member acts on the lock shaft 100, and the guide protrusion 120 is pushed toward the annular protrusion 220 and moves along the edge, and finally stops at the first concave position 610 or the second concave position 620. At the same time, the lock shaft 100 will also rotate around its axial direction by a certain angle. The locking or unlocking state can be easily switched by pressing. The overall structure of the locking structure is simple, occupies a small space, is easy to maintain, and has strong versatility.

[0031] Preferably, the first mounting plate 200 is provided with a first through hole 210 for the lock shaft 100 to pass through, the second mounting plate 300 is provided with a second through hole 310 for the abutting column 110 to pass through, the annular protrusion 220 is provided around the first through hole 210, and the guide protrusion 120 is provided around the second through hole 310.
