Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, in particular to a stage lamp with a lightweight waterproof protective shell. Background Art

[0002] Stage lights are devices commonly used to generate lighting effects in stage performances. They can project colorful light effects during stage performances to create a stage atmosphere. Most of the stage lights in the prior art generally include a bottom chassis, a rotatable support arm is pivoted on the bottom chassis, a lamp head is pivoted on the support arm, and different stage light functional components are installed inside the bottom chassis, the support arm and the lamp head. For example, the bottom chassis mainly installs a control circuit, the support arm mainly installs a lamp head transmission mechanism, the lamp head mainly installs a light source and various light effect modules and a heat dissipation module, etc. Therefore, the mounting shells of various parts of the stage lights need to have strong structural strength to ensure that they can bear the weight of the stage light functional components, and also need to have certain waterproof and moisture-proof properties to prevent external moisture from easily entering the stage light and damaging the functional components.

[0003] In order to ensure that the installation shells of various parts of traditional stage lights have strong structural strength, the installation shells of various parts of the stage lights are generally manufactured by die-casting. The die-cast metal shell can indeed make the installation shell of the stage light have strong load-bearing capacity and structural strength, but it will also cause the stage light installation shell to have defects such as large thickness and heavy weight, resulting in a large overall weight of the stage light, making it difficult to achieve lightweight improvement of the stage light. When a large number of stage lights need to be put into use on the stage, carrying a large number of heavy stage light equipment will undoubtedly bring great inconvenience to the transportation work.

[0005] The utility model discloses a stage lamp with a lightweight waterproof protective shell, comprising a bottom chassis, a support arm is pivotally connected to the bottom chassis, and a lamp head is pivotally connected between the support arms on both sides;

[0006] The bottom chassis or support arm or lamp holder comprises a plastic shell and a support plate which are spliced ​​and connected to each other;

[0007] The plastic shell is formed with a receiving cavity for receiving the functional components of the stage light, and the interior of the plastic shell is integrally formed with an annular reinforcing rib surrounding the receiving cavity;

[0008] The support surface of the support plate is provided with a sealing ring matching the orbit around the annular reinforcement rib;

[0009] Wherein, one end of the annular reinforcement rib away from the plastic shell is sealedly connected to the sealing ring.

[0010] According to the utility model of a stage lamp with a lightweight waterproof casing, an annular sleeve groove is formed on the side of the sealing ring away from the support plate, and the annular reinforcing rib is sleeved in the annular sleeve groove.

[0011] According to the utility model of a stage lamp with a lightweight waterproof protective shell, a plurality of protrusions are formed on one side of the sealing ring close to the support plate, and each of the protrusions elastically abuts against the support plate.

[0012] According to the stage lamp with a lightweight waterproof housing of the utility model, a first protective sheet and a second protective sheet are respectively integrally formed on the outer side surface and the inner side surface of the sealing ring;

[0013] The first protection sheet and the second protection sheet are respectively sealed and attached to the supporting surface of the supporting plate.

[0014] According to the stage lamp with a lightweight waterproof protective shell of the utility model, the first protective sheet and the second protective sheet are arc-shaped sheets respectively;

[0015] One end of the arc-shaped sheet away from the sealing ring is sealed against the supporting surface of the supporting plate;

[0016] An end of the arc-shaped sheet close to the sealing ring is spaced apart from the supporting surface of the supporting plate by a certain movable gap.

[0017] According to the utility model of a stage lamp with a lightweight waterproof casing, the number of the annular reinforcing ribs is several, and the annular reinforcing ribs are spaced apart from each other to form an annular cavity.

[0018] According to the utility model, a stage lamp with a lightweight waterproof shell is provided, wherein a plurality of reinforcing plates are integrally formed inside the plastic shell, and each of the reinforcing plates is arranged and distributed along the circumferential trajectory of the annular reinforcing ribs and connected between each of the annular reinforcing ribs.

[0019] According to the stage lamp with a lightweight waterproof protective shell of the utility model, one end of the reinforcing sheet away from the accommodating cavity extends to the side wall of the plastic shell.

[0020] According to the utility model of a stage lamp with a lightweight waterproof protective shell, a plurality of integrally formed screw columns are arranged on the plastic shell, and each of the screw columns is distributed around the periphery of the surrounding track of the annular reinforcing rib.

[0021] According to the stage lamp with a lightweight waterproof protective shell of the utility model, a plurality of avoidance grooves are formed on the sealing ring, and each of the avoidance grooves avoids each of the screw columns respectively.

[0037] like Figures 1 to 9As shown, a stage light with a lightweight waterproof housing in this embodiment, the main structure of the stage light includes a bottom chassis 1, a support arm 2 and a lamp head 3, the support arm 2 is pivoted on the bottom chassis 1, and the left and right sides of the lamp head 3 are respectively pivoted between the support arms 2. In addition, in the technical solution of the utility model, the bottom chassis 1 or the support arm 2 or the lamp head 3 includes a plastic shell 4 and a support plate 5 that are spliced ​​and connected to each other, and in this embodiment, the structure of the support arm 2 is used as an embodiment, so that the support arm 2 includes a plastic shell 4 and a support plate 5 that are spliced ​​and connected to each other, and a receiving cavity 6 is formed in the plastic shell 4, and the receiving cavity 6 is used to accommodate the functional components of the stage light, and the inside of the plastic shell 4 is integrally formed with an annular reinforcement rib 7 surrounding the receiving cavity 6. In addition, a sealing ring 8 is fixed to the supporting surface of the support plate 5, and the sealing ring 8 is made of soft rubber material, such as rubber or silicone, etc. The sealing ring 8 matches the surrounding trajectory of the annular reinforcement rib 7, that is, the sealing ring 8 and the surrounding trajectory of the annular reinforcement rib 7 are the same, and the end of the annular reinforcement rib 7 away from the plastic shell 4 is sealed and connected to the sealing ring 8.

[0038] It can be understood that the stage light structure of this embodiment sets the shell of the support arm 2 as a plastic shell 4 and a support plate 5 which are connected to each other. The difference from the prior art is that the heavy metal shell formed by die-casting is replaced by a plastic shell 4 with a thinner thickness and lighter weight, which can effectively reduce the weight of the stage light shell. On the other hand, the plastic shell 4 has an annular reinforcing rib 7 integrally formed inside. Under the reinforcing effect of the annular reinforcing rib 7, the plastic shell 4 is not easy to be twisted and deformed, and the structure is more stable, so the load-bearing capacity is stronger, which helps to ensure the structural strength of the stage light shell. On the other hand, the plastic shell The accommodating cavity 6 for accommodating the functional components of the stage light inside the plastic shell 4 is surrounded by the annular reinforcing rib 7, and the supporting surface of the supporting plate 5 is provided with a sealing ring 8 matching the orbit of the annular reinforcing rib 7. When the plastic shell 4 and the supporting plate 5 are assembled with each other, the end of the annular reinforcing rib 7 away from the plastic shell 4 is sealed and connected with the sealing ring 8, so that the supporting plate 5 can seal and close the cavity opening of the accommodating cavity 6, and it is difficult for external moisture to enter the accommodating cavity 6 of the plastic shell 4, so as to avoid the functional components of the stage light installed in the accommodating cavity 6 being easily damaged by moisture, thereby effectively ensuring the waterproof performance of the stage light shell.

[0039] In one embodiment, an annular sleeve groove 9 is formed on the sealing ring 8, and the shape of the annular sleeve groove 9 is the same as that of the sealing ring 8, and the annular sleeve groove 9 is located on the side of the sealing ring 8 away from the support plate 5. When the plastic shell 4 and the support plate 5 are assembled with each other, the annular reinforcement rib 7 is sleeved in the annular sleeve groove 9, and the annular reinforcement rib 7 and the annular sleeve groove 9 are interference fit with each other, and the annular reinforcement rib 7 can be squeezed against each other when inserted into the annular sleeve groove 9, so that the mutual sealing connection between the annular reinforcement rib 7 and the sealing ring 8 can be ensured, so that the support plate 5 can more tightly seal the cavity opening of the accommodating cavity 6, and further improve the waterproof performance of the stage light housing.

[0040] In one embodiment, a plurality of protrusions 10 are integrally formed on the sealing ring 8, and the protrusions 10 are located on a side close to the support plate 5. When the sealing ring 8 is fixed to the support surface of the support plate 5, each protrusion 10 is fixedly inserted into the support plate 5, thereby enhancing the installation stability of the sealing ring 8 on the support plate 5.

[0041] In one embodiment, a first protective sheet 11 and a second protective sheet 12 are integrally formed on the sealing ring 8. The first protective sheet 11 is located on the outer side of the sealing ring 8 and is outside the accommodating cavity 6, while the second protective sheet 12 is located on the inner side of the sealing ring 8 and is inside the accommodating cavity 6, and the first protective sheet 11 and the second protective sheet 12 are respectively sealed and fitted with the supporting surfaces of the supporting plate 5. It can be understood that when the internal air pressure of the accommodating chamber 6 is lower than the air pressure of the external environment, the external atmospheric pressure can compress the first protective sheet 11, so the first protective sheet 11 on the outside of the sealing ring 8 can block the outside air from entering the accommodating chamber 6, thereby helping to further ensure the waterproof and tightness of the accommodating chamber 6, and preventing the functional components of the stage light in the accommodating chamber 6 from being damaged by moisture, thereby achieving better waterproof and moisture-proof effects; similarly, when the internal air pressure of the accommodating chamber 6 is higher than the air pressure of the external environment, the internal air pressure of the accommodating chamber 6 can compress the second protective sheet 12, so the second protective sheet 12 on the inside of the sealing ring 8 can block the air in the accommodating chamber 6 from flowing out to the outside to a certain extent, thereby helping to ensure the airtightness of the accommodating chamber 6, and also conducive to achieving better waterproof and moisture-proof effects.

[0042] In one embodiment, the first protective sheet 11 and the second protective sheet 12 are arc-shaped sheets, respectively, and the outer end of the arc-shaped sheet (i.e., the end away from the sealing ring 8) is sealed and attached to the support surface of the support plate 5, while the inner end of the arc-shaped sheet (i.e., the end close to the sealing ring 8) is spaced a certain distance from the support surface of the support plate 5. The first protective sheet 11 and the second protective sheet 12 of the arc-shaped structure can be more easily deformed by pressure, so when the pressure of air pressure acts on the first protective sheet 11 and the second protective sheet 12, the first protective sheet 11 and the second protective sheet 12 are more easily deformed by pressure and press the support surface of the support plate 5, further ensuring the airtightness of the accommodating cavity 6, thereby achieving a better waterproof and moisture-proof effect.

[0043] In one embodiment, the number of the annular reinforcing ribs 7 is several, and in this embodiment, the number of the annular reinforcing ribs 7 is two, and the two annular reinforcing ribs 7 are spaced apart from each other to form an annular cavity 13. On the one hand, the multiple annular reinforcing ribs 7 formed integrally on the plastic shell 4 can more effectively strengthen the structural strength of the stage light shell, and on the other hand, the annular cavity 13 formed by the two annular reinforcing ribs 7 spaced apart from each other is equivalent to an additional sealed cavity surrounding the periphery of the accommodating cavity 6, which can effectively isolate the external air from entering the accommodating cavity 6, thereby further ensuring the airtightness of the accommodating cavity 6, and thus achieving a better waterproof and moisture-proof effect.

[0044] In one embodiment, a plurality of reinforcing sheets 14 are integrally formed inside the plastic shell 4, and each reinforcing sheet 14 is arranged and distributed along the circumferential trajectory of the annular reinforcing rib 7, and each reinforcing sheet 14 is connected between two annular reinforcing ribs 7, so that each annular reinforcing rib 7 is connected as a whole. This structure can further enhance the structural strength of the stage light shell.

[0045] In one embodiment, the outer end of the reinforcing sheet 14 (i.e., the end away from the accommodating cavity 6) extends to the side wall of the plastic shell 4, and the outer end of the reinforcing sheet 14 is fixedly connected between the annular reinforcing ribs 7 and the side wall of the plastic shell 4, so that each annular reinforcing rib 7 is connected to the side wall of the plastic shell 4 as a whole. This structure can also further enhance the structural strength of the stage light shell.

[0046] In one embodiment, a plurality of screw columns 15 are integrally formed in the plastic shell 4, and the screw columns are used to connect the support plate 5 so that the plastic shell 4 and the support plate 5 are fixedly assembled with each other. At the same time, each screw column 15 is distributed on the periphery of the circumferential track of the annular reinforcement rib 7 and is integrally formed with the annular reinforcement rib 7, so that the annular reinforcement rib 7 and each screw column 15 are connected as a whole. This structure can also further enhance the structural strength of the stage light shell.

[0047] In one embodiment, a plurality of avoidance grooves 16 are formed on the sealing ring 8. When the plastic housing 4 and the support plate 5 are assembled together, each avoidance groove 16 is respectively evaded by each screw column 15. Thus, it is ensured that the sealing ring 8 and the screw column 15 do not interfere with each other, and the plastic housing 4 and the support plate 5 are normally assembled and connected.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
