Description

Technical Field

[0001] The utility model relates to the technical field related to signal amplifiers, in particular to an improved structure of a signal amplifier used for stage lighting control. Background Art

[0002] The existing signal amplifier for stage lighting control includes a shell, a signal amplifier control board arranged in the shell, and a plurality of interfaces, and the interfaces are flush with the opening of the shell, which is also a consistent practice in the art. However, the structure in which the interfaces are flush with the opening cannot block dust and rain, and is easily soaked by rain, especially when it rains, which may cause the signal amplifier equipment to malfunction and may also cause safety hazards. In addition, the hook of the signal amplifier for stage lighting control is fixed in a vertical shape, and the hook of this structure will take up space when stored, which is not conducive to storage. Utility Model Content

[0003] The purpose of the utility model is to provide an improved structure of a signal amplifier for stage lighting control, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the signal amplifier includes a shell, the shell is provided with a downward opening, a signal amplifier control board and a baffle are provided in the shell, the baffle is located on the outside of the signal amplifier control board, the signal amplifier control board is provided with a plurality of interfaces, the baffle is provided with a plurality of through holes corresponding to the interfaces, and the distance from the baffle to the top of the shell is less than the height of the shell.

[0005] The distance from the baffle to the top of the shell is smaller than the height of the shell.

[0006] Preferably, the distance from the baffle to the opening is 2-4 cm.

[0007] Preferably, the signal amplifier further comprises a hook structure, the hook structure comprises a fixing ring and a hook, the fixing ring and the hook are connected with each other via bolts, and the fixing ring is fixedly arranged on the top of the housing.

[0008] Preferably, the fixing ring includes a fixing ring body and a fixing rod, a screw hole is provided in the middle of the ring body, the fixing rod is fixed to the top of the shell, the hook includes a hanging part, a fixing part, and a connecting part, the connecting part is located between the fixing part and the hanging part, the fixing part is provided with a second screw hole, and the fixing ring body and the fixing part are connected by a first bolt.

[0009] Preferably, the connecting portion is provided with a third screw hole, and a second bolt is screwed into the third screw hole.

[0010] Preferably, the hanging portion is arc-shaped, and anti-slip grooves are provided on the inner side of the hanging portion.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The distance from the baffle to the top of the housing of the utility model is less than the height of the housing. Since the housing opening is downward, and the interface is located in the housing and is higher than the opening of the housing, that is, there is a certain distance between the opening of the housing and the interface, it can prevent rain from wetting the interface, so as to ensure that the signal amplifier can still work normally in a rainy environment. At the same time, the hook is movably connected to the fixing ring, so that the hook is in a vertical position when in use and in a horizontal position when not in use, so as to facilitate storage.

[0015] Figure 3 It is a three-dimensional structural diagram of the utility model in a top view when in use.

[0016] In the figure: a shell 1, a shell top 10, a baffle 2, an interface 3, a fixing ring 41, a hook 42, a hanging portion 421, an anti-slip pattern 4211, a connecting portion 422, a fixing portion 423, a first bolt 51, and a second bolt 52. DETAILED DESCRIPTION

[0017] The technical solution in one embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] See also Figure 1-3 :

[0019] An improved structure of a signal amplifier for stage lighting control, the signal amplifier comprises a housing 1, a signal amplifier control panel and a baffle 2 are arranged in the housing 1, the control panel is provided with a plurality of interfaces 3, and the baffle 2 is provided with a plurality of through holes corresponding to the interfaces 3

[0020] The distance from the baffle 2 to the top of the housing 1 is less than the height of the housing 1. Since the housing 1 opens downward and the interface 3 is located inside the housing 1 and higher than the opening of the housing 1, the interface 3 can be prevented from being wetted by rain, so as to ensure that the signal amplifier can still work normally in a rainy environment.

[0021] The distance between the baffle plate 2 and the opening is 2-4 cm. If the distance is too large, materials will be wasted, and if the distance is too short, the rain and dust protection effect will not be achieved.

[0022] The signal amplifier also includes a hook structure, which includes a fixing ring 41 and a hook 42.

[0023] The fixing ring 41 includes a fixing ring body and a fixing rod. A screw hole is provided in the middle of the fixing ring body. The fixing rod is fixed to the top of the housing 1.

[0024] The hook 42 includes a hanging portion 421, a fixing portion 423, and a connecting portion 422. The connecting portion 422 is located between the fixing portion 423 and the hanging portion 421. The fixing portion 423 is provided with a second screw hole. The fixing ring body and the fixing portion 423 are connected by bolts. Since the fixing portion 423 and the fixing ring 41 are movably connected by the first bolt 51, when the signal amplifier needs to be hung, the hook 42 is adjusted to a vertical position and fixed by the first bolt 51.

[0025] When the signal amplifier does not need to be suspended, the hook 42 is adjusted to a lying position by adjusting the first bolt 51 and fixed by the first bolt 51 for easy storage.

[0026] A third screw hole is provided at a position of the connection portion 422 close to the fixing portion 423 , and the signal amplifier is further fixed by a second bolt 52 screwed to the third screw hole when the signal amplifier is suspended.

[0027] In order to increase the contact area and friction between the hanging portion 421 and the supporting body and enhance the stability of the hook, the hanging portion 421 is arc-shaped, and an anti-slip pattern 4211 is provided on the inner side of the hanging portion 421 .
