Description

Technical Field

[0001] The present invention relates to the technical field of stage lights, and more particularly to a push lock and a stage light having the same. Background Art

[0002] A stage light typically includes a lamp head, a support arm for rotating the lamp head, and a chassis for rotating the support arm. During maintenance or transportation, the lamp head and support arm must be locked to prevent them from rotating freely. Current lock structures require that a locking rod be aligned with a lock hole or notch on a lock disk before it can be operated to enter the lock hole or notch for locking, or that the lock disk be free of the locking rod before it can be operated to exit the lock hole or notch for unlocking. This requires one hand to continuously operate the locking rod while the other hand rotates the lamp head or support arm to the correct position to lock or unlock the light. This is inconvenient, especially when performing high-altitude maintenance after the stage light is installed. Summary of the Invention

[0003] In order to overcome at least one of the defects described in the above-mentioned prior art, the present invention provides a push lock, which can be operated regardless of whether the lock rod and the lock disk are aligned or interfere with each other. After the lock rod is released, the lock disk moves to the correct position, and the lock rod automatically locks or unlocks the lock disk.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a push lock, comprising a lock disk and a locking member for locking the lock disk, the locking member comprising a lower mounting plate, a pressing cap and a locking rod located above the lower mounting plate, the lock disk being located below the lower mounting plate, the lower mounting plate being provided with a lower through hole for the locking rod to pass through, and further comprising an elastic retaining member to maintain the locking rod in a balanced position, and further comprising a guide block with a guide groove, the guide groove having an upper locking position and a lower locking position, the pressing cap being connected to a hanging The hook has its end extended into the guide groove, and each time the pressing cap is pressed, the end of the hook will switch between the upper locking position and the lower locking position once, and when the end of the hook is located in the lower locking position, the pressing cap acts on the elastic retaining member to make the locking rod move down and cooperate with the locking portion on the lock disk or have a tendency to cooperate with it, and when the end of the hook is located in the upper locking position, the lower mounting plate acts on the elastic retaining member to make the locking rod move up and disengage from the lock disk or have a tendency to disengage.

[0005] The push lock maintains the lock rod in a balanced position by providing an elastic retaining member, and then uses a guide block with a guide groove to lock the position of the hook connected to the push cap. Each time the push cap is pressed, the end of the hook will switch between the upper locking position and the lower locking position. Since the push cap is not directly connected to the lock rod but acts on the elastic retaining member, even if the lock rod is interfered with by the lock disk and cannot change its position in time, it is always affected by the elastic retaining member. Therefore, after the interference of the lock disk on the lock rod is released, the lock rod will automatically complete the change of position (when the hook is When the end is in the lower locking position, the pressing cap acts on the elastic retaining member to move the locking rod downward and cooperate with the locking portion on the lock disk or has a tendency to cooperate with it; when the end of the hook is in the upper locking position, the lower mounting plate acts on the elastic retaining member to move the locking rod upward and disengage from the lock disk or has a tendency to disengage). There is no need to keep operating the locking rod and the lock disk (or the components connected thereto) at the same time. It is very convenient to use. You can operate the locking rod at any time, and then operate the lock disk (or the components connected thereto). After the lock disk moves (or inches) to the correct position, the locking rod automatically operates.

[0006] Furthermore, the elastic retaining member includes an upper elastic member and a lower elastic member. The two ends of the upper elastic member act on the pressing cap and the locking rod respectively, applying a downward force to the locking rod. The two ends of the lower elastic member act on the lower mounting plate and the locking rod respectively, applying an upward force to the locking rod. Separating the elastic retaining member into the upper elastic member and the lower elastic member facilitates assembly and allows for separate production of the upper and lower elastic members based on different performance requirements.

[0007] Furthermore, the lock rod sidewall is provided with a bump, and the ends of the upper elastic member abut against the upper side of the bump and the pressing cap, while the ends of the lower elastic member abut against the lower side of the bump and the lower mounting plate. The design of the bump facilitates the connection and cooperation between the upper and lower elastic members and the lock rod, simplifying assembly.

[0008] Furthermore, the elastic coefficient of the upper elastic member is greater than the elastic coefficient of the lower elastic member. Thus, when the push cap is pressed, the deformation of the lower elastic member will be greater than the deformation of the upper elastic member. Since the push cap is not directly connected to the lock rod, the displacement of the lock rod is the deformation of the lower elastic member, while the displacement of the push cap is the sum of the deformations of the upper and lower elastic members. Therefore, by making the elastic coefficient of the upper elastic member greater than the elastic coefficient of the lower elastic member, the displacement of the push cap can be reduced while the displacement of the lock rod remains the same, thus avoiding the need for the push cap to protrude too much, which would be unsightly.

[0009] Furthermore, the upper elastic member and / or the lower elastic member is a tower spring, and the narrower end thereof acts on the locking rod. The tower structure has good stability and large deformation space.

[0010] Furthermore, the pressing cap is provided with an escape hole corresponding to the locking rod. The design of the escape hole can reduce the height of the pressing cap protruding from the upper mounting plate, making it more beautiful.

[0011] Furthermore, an upper mounting plate is provided, on which an upper through hole is provided to guide the pressing cap, so that the movement of the pressing cap is smoother and less likely to get stuck.

[0012] Furthermore, a retaining edge is provided on the outer side of the pressing cap to prevent it from falling off from the upper through hole.

[0013] Furthermore, the lower mounting plate is connected to the upper mounting plate at both ends, and is bent in the middle to form a space for accommodating the pressing cap, the locking rod, the elastic retaining member, the hook, and the guide block. In this way, the push lock can exist as a separate component and be integrally mounted on other components.

[0014] Furthermore, the locking portion is a lock hole or a notch. When the lock rod enters the lock hole or the notch, the relative movement of the lock disk, such as rotation or movement, can be restricted.

[0015] Furthermore, the number of the guide blocks is 2 and they are arranged opposite to each other, and each of the two hooks cooperates with one guide block. The two guide blocks cooperate with the two hooks to make the force on the pressing cap more balanced and avoid skewing.

[0016] Furthermore, the guide groove includes a first groove and a second groove located on both sides of a line connecting the upper locking position and the lower locking position, wherein the first groove guides the end of the hook from the upper locking position to the lower locking position in one direction, and the second groove guides the end of the hook from the lower locking position to the upper locking position in one direction. In this way, after the end of the hook moves in the first groove or the second groove, it will return to the lower locking position or the upper locking position under the action of the elastic force of the hook itself; and the first groove and the second groove, which limit the unidirectional movement of the end of the hook, respectively guide the end of the hook from the upper locking position to the lower locking position in one direction, and from the lower locking position to the upper locking position in one direction, so that each time the pressing cap is pressed, the end of the hook will switch between the upper locking position and the lower locking position once, thereby achieving a simple structure and not easy to be damaged.

[0017] Furthermore, the groove depth of the first groove at the upper locking position is greater than the groove depth of the second groove at the upper locking position, so that when the end of the hook passes through the second groove to reach the upper locking position, it automatically enters the first groove, so that the first groove guides the end of the hook when the pressing cap is pressed next time, and the groove depth of the first groove at the lower locking position is less than the groove depth of the second groove at the lower locking position, and the end of the hook always abuts against the bottom of the first groove or the bottom of the second groove, so that when the end of the hook passes through the first groove to reach the lower locking position, it automatically enters the second groove, so that the second groove guides the end of the hook when the pressing cap is pressed next time.

[0018] Furthermore, the first groove includes a first groove section and a second groove section that are interconnected, and one end of the first groove section and the second groove section that are away from each other are respectively connected to the upper locking position and the lower locking position, and the second groove includes a third groove section and a fourth groove section that are interconnected, and one end of the third groove section and the fourth groove section that are away from each other are respectively connected to the upper locking position and the lower locking position, and the connection between the first groove section and the second groove section and the connection between the third groove section and the fourth groove section are closer to the lower mounting plate than the lower locking position, so as to prevent the hook from The end of the hook is limited so that it can be maintained in the lower locking position and will not leave the position under the action of the elastic retaining member, and the second groove section is connected with the first groove section, and the second groove section is deeper, and the third groove section is connected with the fourth groove section, and the end of the hook always abuts against the bottom of the first groove section, the bottom of the second groove section, the bottom of the third groove section or the bottom of the fourth groove section, so that the end of the hook can smoothly transition at the turning point of the first groove and the second groove.

[0019] The present invention also provides a stage light, comprising any of the aforementioned push locks, and also comprising a lamp head for projecting light, a support arm for supporting the rotation of the lamp head, and a chassis for supporting the rotation of the support arm, wherein the push lock is used to lock the lamp head or the support arm, respectively limiting the rotation of the lamp head relative to the support arm and the rotation of the support arm relative to the chassis.

[0028] 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.

[0029] like Figure 1 、 Figure 2 and Figure 4The present invention provides a push lock, comprising a lock disk 100 and a locking member 20 for locking the lock disk 100, the locking member 20 comprising a lower mounting plate 300 and a pressing cap 400 and a locking rod 200 located above the lower mounting plate 300, the lock disk 100 being located below the lower mounting plate 300, the lower mounting plate 300 being provided with a lower through hole 310 for the locking rod 200 to pass through, and further comprising an elastic retaining member 500 for maintaining the locking rod 200 in a balanced position, and further comprising a guide block 600 having a guide groove 610, the guide groove 610 having an upper locking position 620 and a lower locking position 630, the pressing cap 400 being connected to a hook 700, the The end of the hook 700 extends into the guide groove 610. Each time the pressing cap 400 is pressed, the end of the hook 700 will switch once between the upper locking position 620 and the lower locking position 630. When the end of the hook 700 is located at the lower locking position 630, the pressing cap 400 acts on the elastic retaining member 500 to move the locking rod 200 downward to cooperate with the locking portion 110 on the lock disk 100 or has a tendency to cooperate with it. When the end of the hook 700 is located at the upper locking position 620, the lower mounting plate 300 acts on the elastic retaining member 500 to move the locking rod 200 upward to disengage from the lock disk 100 or has a tendency to disengage.

[0030] The push lock maintains the locking rod 200 in a balanced position by setting an elastic retaining member 500, and then uses a guide block 600 with a guide groove 610 to lock the position of the hook 700 connected to the push cap 400. Each time the push cap 400 is pressed, the end of the hook 700 will switch once between the upper locking position 620 and the lower locking position 630. Since the push cap 400 is not directly connected to the locking rod 200 but acts on the elastic retaining member 500, even if the locking rod 200 is interfered with by the lock disk 100 and cannot change its position in time, it is always affected by the elastic retaining member 500. Therefore, after the interference of the lock disk 100 on the locking rod 200 is released, the locking rod 200 will automatically complete the position change. For example, when the end of the hook 700 is located at the lower locking position 630, the pressing cap 400 acts on the elastic retaining member 500 to move the locking rod 200 downward to cooperate with the locking portion 110 on the lock plate 100 (e.g., Figure 2 At this time, the locking rod 200 is aligned with the locking portion 110, and the locking rod 200 can move downward smoothly under the action of the elastic retaining member 500) or has a tendency to cooperate with it (such as Figure 3At this time, the locking rod 200 is not aligned with the locking portion 110, and the locking rod 200 cannot be smoothly moved downward under the action of the elastic retaining member 500). When the end of the hook 700 is located at the upper locking position 620, the lower mounting plate 300 acts on the elastic retaining member 500 to move the locking rod 200 upward and away from the lock disk 100 (as shown in FIG. Figure 4 At this time, the lock plate 100 does not interfere with the lock rod 200, and the lock rod 200 can move upward under the action of the elastic retaining member 500) or has a tendency to disengage (such as Figure 5 , the lock disk 100 interferes with the lock rod 200, and the lock rod 200 cannot move upward under the action of the elastic retaining member 500). There is no need to keep operating the lock rod 200 and the lock disk 100 (or the components connected thereto) at the same time. It is very convenient to use. You can operate the lock rod 200 at any time, and then operate the lock disk 100 (or the components connected thereto). After the lock disk 100 moves (or slightly moves) to the correct position, the lock rod 200 automatically moves. For example, Figure 3 Even if the locking rod 200 is not aligned with the locking portion 110 at this time, the locking rod 200 cannot be smoothly moved downward under the action of the elastic retaining member 500. However, when the lock plate 100 continues to move to align the locking rod 200 with the locking portion 110, the locking rod 200 will move under the action of the elastic retaining member 500, thereby automatically completing the locking. Figure 5 Even if the lock disk 100 interferes with the lock rod 200 at this time, the lock rod 200 cannot move up under the action of the elastic retaining member 500. However, when the lock disk 100 continues to move so that the lock disk 100 does not interfere with the lock rod 200, the lock rod 200 will move up under the action of the elastic retaining member 500, thereby automatically completing the unlocking.

[0031] In this embodiment, the hook 700 is L-shaped, with a longitudinal end being fastened to the pressing cap 400 by a screw, and a transverse end being hung in the guide groove 610 of the guide block 600 .

[0032] In a preferred embodiment of the present invention, the elastic retaining member 500 includes an upper elastic member 510 and a lower elastic member 520. The ends of the upper elastic member 510 act on the pressing cap 400 and the locking rod 200, respectively, exerting a downward force on the locking rod 200. The ends of the lower elastic member 520 act on the lower mounting plate 300 and the locking rod 200, respectively, exerting an upward force on the locking rod 200. Separating the elastic retaining member 500 into the upper elastic member 510 and the lower elastic member 520 facilitates assembly and allows for separate production of the upper and lower elastic members 510, 520 according to differing performance requirements.

[0033] When the end of the hook 700 is located at the upper locking position 620, the pressing cap 400 is pressed, which compresses the upper elastic member 510, and the upper elastic member 510 pushes the locking rod 200 to move and compresses the lower elastic member 520 at the same time. The displacement of the pressing cap 400 is the sum of the deformation of the upper elastic member 510 and the lower elastic member 520, and the displacement of the locking rod 200 is the deformation of the lower elastic member 520. Since the pressing cap 400 is not directly connected to the locking rod 200, but acts on the upper elastic member 510, regardless of whether the locking rod 200 is aligned with the locking portion 110 on the lock disk 100, the end of the hook 700 can move to the The lower locking position 630 is fixed there. If the locking rod 200 is aligned with the locking portion 110 on the lock disk 100, the locking rod 200 directly enters the locking portion 110 to lock the lock disk 100. If the locking rod 200 is not aligned with the locking portion 110 on the lock disk 100, the locking rod 200 resists the lock disk 100, and the upper elastic member 510 continuously applies a downward elastic force to the locking rod 200, causing it to have a tendency to move downward, until the lock disk 100 moves to align the locking rod 200 with the locking portion 110. At the time, the locking rod 200 automatically extends under the action of the upper elastic member 510 to lock the lock disk 100.

[0034] When the end of the hook 700 is located in the lower locking position 630, the pressing cap 400 is pressed, and the end of the hook 700 is disengaged from the lower locking position 630. If the lock disk 100 does not interfere with the lock rod 200, the pressing cap 400 will move upward under the joint action of the upper elastic member 510 and the lower elastic member 520 until the end of the hook 700 moves to the upper locking position 620, and the lock rod 200 will move to the equilibrium position under the action of the lower elastic member 520, thereby unlocking the lock disk 100. The lock disk 100 interferes with the lock rod 200 and prevents it from moving. The pressing cap 400 will move upward under the sole action of the upper elastic member 510 until the end of the hook 700 moves to the upper locking position 620, and the lower elastic member 520 will continue to apply an upward force to the lock rod 200, causing it to have a tendency to move downward. As the lock disk 100 moves, the interference with the lock rod 200 disappears, and the lock rod 200 will move upward to a balanced position under the sole action of the lower elastic member 520, thereby unlocking the lock disk 100.

[0035] The connection between the upper elastic member 510 and the pressing cap 400 and the locking rod 200 , and the interaction between the lower elastic member 520 and the lower mounting plate 300 and the locking rod 200 can be generated by connection or by abutment.

[0036] In other embodiments, the upper elastic member 510 may provide an upward pulling force on the locking rod 200, and the lower elastic member 520 may provide a downward pulling force on the locking rod 200. In this case, the upper elastic member 510 is required to be connected with the pressing cap 400 and the locking rod 200, and the interaction between the lower elastic member 520 and the lower mounting plate 300 and the locking rod 200 must be generated by connection.

[0037] In a preferred embodiment of the present invention, a protrusion 210 is provided on the side wall of the locking rod 200. The ends of the upper elastic member 510 abut against the upper side of the protrusion 210 and the pressing cap 400, while the ends of the lower elastic member 520 abut against the lower side of the protrusion 210 and the lower mounting plate 300. The design of the protrusion 210 facilitates the connection and cooperation between the upper and lower elastic members 510, 520, and the locking rod 200, simplifying assembly.

[0038] In this embodiment, the protrusion 210 is annular, circumferentially arranged around the locking rod 200 , and approximately located in the middle of the locking rod 200 .

[0039] In a preferred embodiment of the present invention, the elastic coefficient of the upper elastic member 510 is greater than the elastic coefficient of the lower elastic member 520. In this way, when the pressing cap 400 is pressed, the deformation of the lower elastic member 520 will be greater than the deformation of the upper elastic member 510. Since the pressing cap 400 is not directly connected to the locking rod 200, the displacement of the locking rod 200 is the deformation of the lower elastic member 520, while the displacement of the pressing cap 400 is the sum of the deformations of the upper and lower elastic members 510 and 520. Therefore, by making the elastic coefficient of the upper elastic member 510 greater than the elastic coefficient of the lower elastic member 520, the displacement of the pressing cap 400 can be reduced when the displacement of the locking rod 200 is the same, avoiding the need for the pressing cap 400 to protrude too much, which is not aesthetically pleasing.

[0040] In this embodiment, the elastic coefficient of the upper elastic member 510 is twice the elastic coefficient of the lower elastic member 520 .

[0041] In a preferred embodiment of the present invention, the upper elastic member 510 and / or the lower elastic member 520 is a tower spring, and the narrower end thereof acts on the locking rod 200. The tower structure has good stability and a large deformation space.

[0042] In a preferred embodiment of the present invention, the pressing cap 400 is provided with an escape hole 410 corresponding to the locking rod 200. The design of the escape hole 410 can reduce the height of the pressing cap 400 protruding from the upper mounting plate 800, making it more aesthetically pleasing.

[0043] In this embodiment, the avoidance hole 410 also guides the locking rod 200 .

[0044] In a preferred embodiment of the present invention, an upper mounting plate 800 is further included, and an upper through hole 810 is provided on the upper mounting plate 800 to guide the pressing cap 400, thereby making the movement of the pressing cap 400 smoother and less prone to jamming.

[0045] In this embodiment, a guide cylinder 820 for guiding the pressing cap 400 is provided around the upper through hole of the upper mounting plate 800 . The guide cylinder 820 is located on a side of the upper mounting plate 800 close to the lower mounting plate 300 .

[0046] In this embodiment, the lower through hole 310 also guides the locking rod 200 .

[0047] In a preferred embodiment of the present invention, a retaining edge 420 is provided on the outer side of the pressing cap 400 to prevent it from falling off from the upper through hole 810 .

[0048] In this embodiment, when the locking rod 200 is in a balanced position, the elastic retaining member 500 presses against the pressing cap 400, so that the retaining edge 420 presses against the upper mounting plate 800, thereby ensuring that the pressing cap 400 does not swing freely, and the structure appears more compact and firm.

[0049] In a preferred embodiment of the present invention, the lower mounting plate 300 is connected to the upper mounting plate 800 at both ends, and is bent in the middle to form an accommodating space 320 for accommodating the pressing cap, the locking rod 200, the elastic retaining member 500, the hook 700, and the guide block 600. In this way, the push lock can exist as a separate component and be integrally mounted on other components.

[0050] In a preferred embodiment of the present invention, the locking portion 110 is a locking hole or a notch. When the locking rod 200 enters the locking hole or the notch, the relative movement of the locking disk 100, such as rotation or movement, can be restricted.

[0051] In this embodiment, the locking disk 100 rotates, and the locking portions 110 are distributed around the locking disk 100 .

[0052] In a preferred embodiment of the present invention, the number of the guide blocks 600 is two and they are arranged opposite each other, and the two hooks 700 are each engaged with one guide block 600. The two guide blocks 600 and the two hooks 700 cooperate together to make the force on the pressing cap 400 more balanced and prevent it from tilting.

[0053] In this embodiment, the guide block 600 is fixed to the lower mounting plate 300 and is located between the lower mounting plate 300 and the upper mounting plate 800 .

[0054] like Figure 1 、 Figure 6 In a preferred embodiment of the present invention, the guide groove 610 includes a first groove 611 and a second groove 612 located on both sides of the line connecting the upper locking position 620 and the lower locking position 630.
