Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a stage lamp capable of preventing a shell from being mistakenly disassembled. Background Art

[0002] The outer shell of a stage lamp holder is generally composed of several sides, each of which is fixedly connected to the lamp body bracket. When the parts inside the lamp holder need to be maintained, the detachable lamp shell on any side is selected to be disassembled to repair the inside of the lamp shell. However, since there are many parts inside stage lamps and the arrangement order is complicated, it is often found that the parts that need to be repaired are closer to the other side of the lamp shell after disassembling the lamp shell, which leads to repeated disassembly and assembly of the lamp shell, reducing the sealing of the connection between the lamp shells and increasing the manpower and time for maintaining the lamps. Utility Model Content

[0003] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a stage lamp which can prevent the outer shell from being disassembled by mistake, limits the disassembly order of the lamp shell, and requires disassembly from one side first before disassembly from the other side. In the lamp body assembly type, parts that often need to be maintained are designed on the side of the lamp shell that is disassembled first as much as possible, thereby reducing the number of times the lamp shell is disassembled and ensuring the airtightness of the lamp shell connection.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stage lamp that prevents the outer shell from being accidentally disassembled, comprising a support arm and a lamp head pivotally connected to the support arm on left and right sides, the lamp head comprising a light source, a light output lens and a lamp stand, the light source is arranged at one end of the lamp stand, the light output lens is located at the other end of the lamp stand away from the light source, and also includes a lamp housing arranged outside the lamp stand, the lamp housing forms a cavity for accommodating the lamp stand, the lamp housing comprises a first lamp housing and a second lamp housing fixedly installed by a first screw and a second screw, the first screw and the second screw are provided with nuts, the first screw passes through the first lamp housing and is fixed to the lamp stand, the nut of the first screw is located outside the cavity, the second screw passes through the lamp stand and is fixed to the second lamp housing, and the nut of the second screw is located inside the cavity.

[0005] The lamp housing forms a cavity for accommodating the lamp holder. Since the second screw passes through the lamp holder and is fixed to the second lamp housing, the nut of the second screw is located within the cavity. Therefore, the second screw can be used to prevent the second lamp housing from being disassembled from the outside. When the stage light needs to be repaired, it can be stipulated that it can only be disassembled from the first lamp housing, thereby avoiding accidental disassembly during maintenance and reducing the probability of repeated disassembly of the lamp housing.

[0006] Furthermore, the first lamp housing and the second lamp housing are respectively located at the front and rear sides of the lamp holder, and the cavity is formed by the first lamp housing and the second lamp housing being buckled together. The lamp housing is only composed of the first lamp housing and the second lamp housing, and does not need to be matched with the lamp holder, thereby reducing the number of connecting parts.

[0007] Furthermore, it also includes a light-emitting cover for covering the light-emitting lens, the light-emitting cover is fixed to the lamp holder, the lamp holder is located at the light-emitting lens and is further provided with a light-emitting plate, the lamp holder is located at the light source and is further provided with a heat-dissipating substrate, the light-emitting plate and the heat-dissipating substrate divide the cavity into a top cavity, a middle cavity, and a bottom cavity:

[0008] The top cavity is formed by the light emitting cover, the light emitting plate and the lamp housing;

[0009] The middle cavity is formed by the light emitting plate, the heat dissipation substrate and the lamp housing;

[0010] The bottom cavity is formed by the heat dissipation substrate and the lamp housing. The three cavities formed by the lamp housing, the light emitting plate and the heat dissipation substrate can enhance the sealing performance inside the stage lamp and reasonably divide the space.

[0011] Furthermore, at least two of the second screws are arranged in the top cavity, so as to ensure that the force of the lamp housing is balanced and the end of the lamp housing is fixed, thereby ensuring the connection stability between the lamp housing and the lamp holder.

[0012] Furthermore, at least two of the first screws are disposed in the bottom cavity to fix the bottom end of the lamp housing to the lamp stand to ensure that the lamp housing does not fall off.

[0013] Furthermore, the middle cavity further comprises at least two third screws, the third screws passing through the first lamp housing and fixed to the second lamp housing. The first lamp housing and the second lamp housing can be directly connected by the third screws, thereby enhancing the tightness and airtightness of the connection between the two.

[0014] Furthermore, the lamp holder is provided with a mounting ring corresponding to the second screw, and the second screw passes through the mounting ring and is fixed to the second lamp housing. The mounting ring has a simple structure, a tight connection, and is easy to process.

[0015] Furthermore, the inner side wall of the second lamp housing is integrally formed with a mounting column, the mounting column is provided with a blind hole with an internal thread, and the second screw is fixedly connected to the blind hole. The blind hole further prevents the second screw from being removed from the lamp housing shell, while ensuring the airtightness of the connection between the second screw and the second lamp housing.

[0016] Furthermore, a sealing rubber ring is provided at the connection between the first screw and the first lamp housing, thereby ensuring the airtightness of the connection between the first screw and the first lamp housing.

[0017] Furthermore, it also includes an effect module that is plugged in and out from one side of the lamp holder, and the first lamp housing is located at the plugging and unplugging side of the effect module. It is convenient to repair the effect module that is plugged in and out from one side after removing the first lamp housing, so that the repair steps are single and errors can be avoided.
