Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of stage lights, and particularly to a novel lifting and gripping component and a stage light using the same. Background Art
[0002] Generally, the handles of stage lights are placed on both sides of the chassis, and the handles protruding outside the chassis look particularly obtrusive, seriously affecting the overall appearance of the stage lights. Therefore, folding handles and telescopic handles have emerged in existing stage lights. However, the designs of these handles still have certain defects. For example, this kind of folding handle can usually only be folded upward from the bottom and blocked at a certain angle to achieve upward lifting. However, when the handle is stored, it will be in a drooping state, and the staff still needs to bend down at a large angle to reach the handle, making it relatively laborious to move the stage light. Moreover, when the handle is stored, it is in a drooping state, which is inconsistent with the common design of the handle facing upward and does not look very beautiful.
[0003] Another example is that the telescopic handle is similar to the telescopic handle of a suitcase. Although the overall beauty of the lamp is not affected after the handle is retracted, its cost is high and its reliability is poor. For example, the telescopic handle may not work properly in a low-temperature environment, which is a potential use obstacle for users.

[0031] As attached Figure 1 To Attachment Figure 7As shown, the invention provides a new type of handle assembly installed on a stage light, which includes a base plate 1, a handle member 3 rotatably connected to the base plate 1 through a rotating shaft 2, and a locking member 4 slidably arranged on the base plate 1, the handle member 3 has a retracted state for storage and an unfolded state for easy lifting and holding, a locking structure is arranged between the rotating shaft 2 and the locking member 4, the locking structure includes a clamping protrusion 41 or a clamping groove arranged on the locking member 4, and a clamping groove 20 or a clamping protrusion arranged on the circumferential surface of the rotating shaft 2 and cooperating with the clamping protrusion 41 or the clamping groove. During the sliding process of the locking member 4, the clamping protrusion 41 can cooperate with or disengage from the clamping groove 20. When the clamping protrusion 41 and the clamping groove 20 cooperate, the handle member 3 is fixed relative to the base plate 1 so that the handle member 3 is maintained in the lifting and holding state; when the clamping protrusion 41 and the clamping groove 20 disengage, the handle member 3 can be rotated relative to the base plate 1 so that the handle member 3 is switched from the lifting and holding state to the retracted state.
[0032] Specifically, the locking member 4 is provided with a locking protrusion 41, and the rotating shaft 2 is correspondingly provided with a locking groove 20; or the locking member 4 is provided with a locking groove, and the rotating shaft 2 is correspondingly provided with a locking protrusion; any one of the above two configurations can be selected.
[0033] The coordination between the protrusion 41 and the slot 20 can effectively enhance the stability of the handle 3 in the handle state, and the two side surfaces of the protrusion 41 can respectively correspond to the two side walls of the slot 20 to prevent the handle 3 from sagging or warping. Compared with the prior art, the locking structure created by the present invention has better effects in terms of wear resistance, durability, and stability.
[0034] As attached Figure 2 As shown, the rotating shaft 2 includes a matching portion 21 and a pivot portion 22 arranged at one end of the matching portion 21, the card slot 20 or the card protrusion on the rotating shaft 2 is arranged on the matching portion 21, and the rotating shaft 2 is rotatably connected to the base plate 1 through the pivot portion 22, so that the matching locking of the card protrusion 41 and the card slot 20 can be achieved during the rotation of the rotating shaft 2.
[0035] As attached Figure 1 As shown, a first return spring 5 is arranged between the rotating shaft 2 and the base plate 1, and the first return spring 5 is used to act on the rotating shaft 2 to automatically return to the convergence state from the lifting state of the lifting member 3 when the locking protrusion 41 and the locking groove 20 are out of engagement. Specifically, the first return spring 5 is a torsion spring, and the other end of the matching portion 21 of the rotating shaft 2 is provided with a sleeve portion 23 for sleeved by the first return spring 5. One end of the first return spring 5 is connected to the base plate 1, and the end is clamped on the clamping block 82 of the connecting plate 8 fixedly connected to the base plate 1, and the other end is connected to the free end of the sleeve portion 23 to realize the automatic reset of the lifting member 3.
[0036] As shown in the appendix Figure 2 and the appendix Figure 7 As shown, a connecting portion 24 is provided at the free end of the pivoting portion 22. The gripping member 3 is provided with a non-circular through hole 31. The front end of the connecting portion 24 is flat. After the rotating shaft 2 is inserted into the through hole 31 through the connecting portion 24, the connecting portion 24 and the gripping member 3 are fixedly connected together by a fastener, thereby realizing the synchronous linkage between the gripping member 3 and the rotating shaft 2.
[0037] As shown in the appendix Figure 1 As shown, a second return spring 6 is provided between the locking member 4 and the substrate 1. The second return spring 6 is used to act on the locking member 4 to slide and engage with the rotating shaft 2 when the convex 41 and the card slot 20 are in corresponding positions; the second return spring 6 is a tension spring. One end of the second return spring 6 is connected to the substrate 1. Specifically, this end is connected to the hook 40 of the limiting plate 7 fixedly connected to the substrate 1, and the other end is connected to the hook 40 of the locking member 4.
[0038] In this embodiment, the locking member 4 includes a flat plate portion 42 and folding portions 43 formed by folding the same side of both side ends of the flat plate portion 42. The folding portions 43 are provided with through holes 431 for the rotating shaft 2 to pass through. Specifically, the convex 41 or the card slot of the locking member 4 is provided on the side wall of the through hole 431, which facilitates the engagement or disengagement between the locking structures, thereby improving the matching degree between the locking member 4 and the rotating shaft 2.
[0039] In this embodiment, receiving grooves 100 are provided at both side ends of the substrate 1. The substrate 1 has a protruding T-shaped boss. Among them, the receiving grooves 100 are formed on both sides of the T-shaped boss. The substrate 1 is fixedly connected with a limiting plate 7 located in the receiving grooves 100. The limiting plate 7 is provided with a first pivoting hole 71. The rotating shaft 2 is rotatably connected to the first pivoting hole 71 through the pivoting portion 22; in addition, a connecting plate 8 is fixedly connected to the limiting plate 7. The connecting plate 8 is provided with a second pivoting hole 81. The rotating shaft 2 is rotatably connected to the second pivoting hole 81 through the sleeving portion 23. The first pivoting hole 71 and the second pivoting hole 81 are both pivotally connected to the rotating shaft 2, effectively enhancing the stability of the rotating shaft 2 during rotation and ensuring the mechanical transmission effectiveness between components. Further, the maximum diameter of the engaging portion 21 is greater than the maximum diameters of the pivoting portion 22 and the sleeving portion 23, so that the engaging portion 21 is clamped between the limiting plate 7 and the connecting plate 8 to prevent the axial offset of the rotating shaft 2.
[0040] As shown in the appendix Figure 1 、appendix Figure 3 and appendix Figure 4As shown, the limiting plate 7 is fixedly connected to the connecting plate 8 through a connecting column 9. A strip-shaped guiding hole 432 is formed in the folding part 43 of the locking member 4. The connecting column 9 is inserted into the strip-shaped guiding hole 432 so that the locking member 4 slides relative to the substrate 1. The cooperation of the strip-shaped guiding hole 432 and the connecting column 9 realizes the sliding of the locking member 4.
[0041] As shown in the Figure 1 accompanying drawings, an avoidance groove 102 for accommodating the lifting handle 3 when the lifting handle 3 rotates to the converging state is further provided on the substrate 1, so that the lifting handle 3 can be flush with the side end of the substrate 1 when in the converging state, without being obtrusive, and the overall appearance is better.
[0042] In this embodiment, a pushing part 44 is fixedly arranged on the locking member 4, a cover plate 10 is fixedly arranged on the substrate 1, a limiting hole 101 for the pushing part 44 to extend to the outside is formed in the cover plate 10, and the pushing part 44 can slide in the limiting hole 101 and drive the locking member 4 to slide along with it. An operator can drive the pushing part 44 to drive the locking member 4 to unlock.
[0043] As shown in the Figure 5 accompanying drawings, the lifting handle 3 is in a U shape, and the shape of the cover plate 10 matches the U-shaped opening of the lifting handle 3 when in the converging state. The cover plate 10 hides components such as the rotating shaft 2, the locking member 4, the locking structure, the first return spring 5 and the second return spring 6, making the overall appearance more beautiful.
[0044] The specific working principle is as follows. When lifting is required, the lifting handle 3 rotates downward and drives the rotating shaft 2 to rotate at the same time. When the card slot 20 of the rotating shaft 2 and the convex card 41 of the locking member 4 are in relative positions, the second return spring 6 pulls the locking member 4 downward under the action of elastic force, so that the convex card 41 is stuck into the card slot 20 for locking. Due to the limiting effect between the convex card 41 and the card slot 20, the lifting handle 3 can be kept in the lifting state, facilitating an operator to perform actions such as lifting and carrying; when convergence is required, the locking member 4 is driven to move upward, so that the convex card 41 disengages from the card slot 20. At this time, the lifting handle 3 is switched from the lifting state to the converging state under the torsion action of the first return spring 5.
[0045] The present invention also provides a stage light, which includes a lamp housing, and the novel lifting assembly is fixedly arranged on the lamp housing. We lift or carry the stage light through the lifting assembly.
[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various equivalent changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
