Push type dismounting device for stage light

Abstract

This invention relates to a press-type disassembly device for a stage light, comprising a light body and a connecting frame. The light body has a pull-out slot, and the connecting frame is connected to a plug-in block. The connecting frame engages with the pull-out slot of the light body via the plug-in block. A stop pin is slidably mounted on the light body, having a stop position and an unlock position during sliding. In the stop position, the stop pin abuts against the plug-in block, thus restricting the plug-in block. In the unlock position, the stop pin and the plug-in block no longer abut against each other. A pressing block is also slidably mounted on the light body. When the pressing block is pressed and slids, it pushes against a second inclined surface via a first inclined surface, thus driving the plug-in block to slide from the stop position to the unlock position. To unlock, simply press the pressing block downwards. Because the first and second inclined surfaces are in close contact, as the pressing block moves downwards, the first inclined surface pushes the second inclined surface, thereby causing the stop pin to retract to the unlock position, allowing for convenient and quick disassembly.

[0012] Further defined, the direction in which the stop pin slides is a first direction, the direction in which the pressing block slides is a second direction, and the first direction and the second direction are perpendicular to each other.

[0013] It is further defined that the first direction is parallel to the radial direction of the lamp body, while the second direction is parallel to the axial direction of the lamp body.

[0014] Further defined, the acute angle ∠A formed by the first inclined plane and the horizontal plane is in the range of 30°-60°, and the acute angle ∠B formed by the second inclined plane and the horizontal plane is in the range of 30°-60°, wherein the acute angle ∠A and the acute angle ∠B are equal.

[0015] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0016] When unlocking, simply press down on the pressing block.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0029] This application further improves the technical solution of patent application number 202520934648X, entitled "A Detachable Connection Device for a Lamp Fixture". The unlocking method of the stop pin is changed from the previous toggle type to the press type, improving the convenience of use. The specific technical solution is as follows:

[0030] As attached Figure 1 and attached Figure 2As shown, a press-type disassembly device for stage lights includes a lamp body 1 and a connecting frame 2. The lamp body 1 contains a light source, lens assembly, etc., to achieve various lighting effects of the stage lights. The connecting frame 2 is U-shaped, with its two ends connected to the two sides of the lamp body 1 to facilitate lifting, hanging, and supporting the lamp body 1.

[0031] The lamp body 1 is provided with a pull-out slot 11, and the connecting frame 2 is connected to a plug-in block 21. The connecting frame 2 is detachably connected to the lamp body 1 by engaging with the pull-out slot 11 of the lamp body 1 through the plug-in block 21. The lamp body 1 is slidably provided with a stop pin 3, which has a stop position and an unlock position during sliding. When the stop pin 3 slides to the stop position, it abuts against the plug-in block 21, thereby preventing the plug-in block 21 from being removed from the pull-out slot 11. When the stop pin 3 slides to the unlock position, the stop pin 3 and the plug block 21 lose their abutment, thereby allowing the plug block 21 to be removed from the slot 11. A pressing block 4 is also slidably provided on the lamp body 1. The pressing block 4 is provided with a first inclined surface 41. The stop pin 3 is provided with a second inclined surface 31 that fits against the first inclined surface 41. When the pressing block 4 is pressed and slids, it supports the second inclined surface 31 through the first inclined surface 41, thereby driving the plug block 21 to slide from the stop position to the unlock position.

[0032] When unlocking, as shown in the attached document Figure 4 As shown, simply press down on the pressing block 4. Since the first inclined surface 41 and the second inclined surface 31 support each other, during the downward movement of the pressing block 4, the first inclined surface 41 can push the second inclined surface 31, thereby causing the stop pin 3 to retract to the unlocked position. At this time, the connecting bracket 2 can be disassembled.

[0033] When locked, as shown in the attached document Figure 3 As shown, a first spring 6 is provided between the stop pin 3 and the lamp body 1 to keep the stop pin 3 in the stop position or to automatically reset it from the unlock position to the stop position. The first spring 6 is used to ensure that the stop pin 3 can automatically reset when it is no longer pressed, thus completing the locking action.

[0034] As attached Figure 3 As shown, the lamp body 1 is provided with a first groove 12 that is adapted to a portion of the stop pins 3. The lamp body 1 is provided with a fixing block 5. The fixing block 5 is provided with a second groove 51 that is adapted to another portion of the stop pins 3. When the fixing block 5 is fixed to the lamp body 1, the first groove 12 and the second groove 51 form a sliding groove 100 in which the stop pins 3 slide. The stop pins 3 can be adapted to the sliding groove 100. Therefore, the stop pins 3 can move back and forth in the sliding groove 100 to switch between the stop position and the unlock position.

[0035] As attached Figure 6As shown, guide rail step grooves 121 extending along their length direction are provided on both sides of the first groove 12. Two extension wings 33 are provided opposite to each other on the circumferential surface of the stop pin 3. The two extension wings 33 respectively overlap the guide rail step grooves 121 on both sides. The extension wings 33 and the guide rail step grooves 121 cooperate with each other to further improve the smoothness and stability of the stop pin 3. At the same time, when the fixing block 5 is fixed, it cooperates with the lamp body 1 to clamp the extension wings 33 in the guide rail step grooves 121, so that the stop pin 3 can move axially and be fixed circumferentially.

[0036] As attached Figure 3 Or attached Figure 4 and attached Figure 10 As shown, a clearance groove 52 is provided through the middle of the fixed block 5, and a protrusion 32 that matches the clearance groove 52 is fixedly provided on the circumferential surface of the stop pin 3. The second inclined surface 31 is provided on the protrusion 32. When the stop pin 3 slides, the protrusion 32 can move back and forth in the clearance groove 52. The clearance groove 52 allows the stop pin 3 to have sufficient room to move. In addition, the protrusion 32 and the clearance groove 52 are adapted to each other, which further improves the fit of the stop pin 3 and the accuracy of directional sliding.

[0037] As attached Figure 5 Appendix Figure 8 and attached Figure 10 As shown, the pressing block 4 is also provided with a third groove 42 that is adapted to a portion of the stop pin 3. An outwardly extending portion 43 is provided on the pressing block 4 and on both sides of the third groove 42. The fixing block 5 is provided with a limiting groove 53 for the extension portion 43 to be accommodated therein. When the pressing block 4 is pressed, the extension portion 43 on it can move in the limiting groove 53. The limiting groove 53 is limited to the up and down movement of the pressing block 4, thereby limiting the movement direction of the pressing block 4.

[0038] As attached Figure 5 Appendix Figure 8 and attached Figure 10 As shown, a limiting post 44 is provided on the lower side of the extension portion 43, and a receiving groove 14 corresponding to the position of the limiting post 44 is provided on the lamp body 1. The pressing block 4 is provided with a second spring 7 that automatically resets after the pressing block 4 is pressed. One end of the second spring 7 is sleeved on the limiting post 44, and the other end is accommodated in the receiving groove 14. The second spring 7 is mainly used to allow the pressing block 4 to automatically reset when the pressing force is lost, so as to facilitate the next pressing operation.

[0039] As attached Figure 3As shown, the sliding direction of the stop pin 3 is the first direction, and the sliding direction of the pressing block 4 is the second direction. The first direction and the second direction are perpendicular to each other. The first direction is parallel to the radial direction of the lamp body 1, while the second direction is parallel to the axial direction of the lamp body 1, so that the pressing block 4 acts on the stop pin 3 with positive stress, making it easier to press.

[0040] As attached Figure 9 As shown, the acute angle ∠A formed by the first inclined surface 41 and the horizontal surface ranges from 30° to 60°, and the acute angle ∠B formed by the second inclined surface 31 and the horizontal surface ranges from 30° to 60°. The acute angles ∠A and ∠B are equal. Specifically, the acute angles ∠A and ∠B can be designed to be any one of 40°, 45°, and 50°, preferably 45°, to improve the fit between the first inclined surface 41 and the second inclined surface 31 and facilitate driving.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
