Description

Technical Field

[0001] This utility model relates to the field of explosion-proof lamp technology, and in particular to the lamp body of an explosion-proof double-headed lamp with an IP67 protection rating. Background Technology

[0002] Explosion-proof double-headed lights, also known as double-headed emergency lights, are generally used in flammable and explosive hazardous locations and environments such as oil extraction, chemical plants, or military industries for emergency safety evacuation and lighting during power outages. For explosion-proof double-headed lights to be used, the lamp body must meet the IP67 protection rating. In existing technology, the lamp body is sealed with sealant during manufacturing to achieve the IP67 protection rating. However, the use of sealant is limited by its manufacturing process; it requires manual application, heavily relying on the operator's skill level; furthermore, the sealant requires a long curing time, and there is a high risk of sealant overflow due to operational issues. Utility Model Content

[0003] The purpose of this utility model is to provide a lamp body for an explosion-proof double-headed lamp with an IP67 protection rating, which can solve the above-mentioned technical problems.

[0004] This utility model provides a lamp body for an explosion-proof double-headed lamp with an IP67 protection rating, comprising:

[0005] The lamp housing and the light source board installed inside the lamp housing, the lamp housing is recessed to form an installation space, and the light source board is installed at the bottom of the installation space;

[0006] The sealing groove is located on the periphery of the installation space, and a sealing ring is installed inside the sealing groove, with the diameter of the sealing ring being greater than the depth of the sealing groove.

[0007] The lampshade and the face cover are sequentially mounted on the lamp housing and fixed to the face cover by several first connectors passing through the lamp housing. After fixing, the lampshade is restricted between the contact surface of the lamp housing and the face cover, and the lampshade squeezes the sealing ring after contacting the sealing ring.

[0008] As a further technical solution, the light source board is equipped with several LED beads, which are arranged in a regular pattern.

[0009] As a further technical solution, the light source board is provided with several mounting holes, and several second connectors pass through the mounting holes to fix the light source board at the bottom of the mounting space.

[0010] As a further technical solution, the outer edge of the lamp housing is provided with a mounting surface that is lower than the contact surface of the lamp housing, and a number of fixing holes are provided on the mounting surface, with a number of first connectors passing through the number of fixing holes.

[0011] As a further technical solution, the faceplate includes:

[0012] The connecting part and the clamping part are provided. The outer edge of the connecting part is adapted to the outer surface of the lamp housing, and the clamping part is provided on the inner surface of the connecting part.

[0013] As a further technical solution, the lampshade includes:

[0014] The lamp housing has a limiting part and a cover, with the cover mounted on the limiting part; in the connected state, the limiting part is positioned between the mounting surface of the lamp housing and the pressing part.

[0015] As a further technical solution, the limiting part is provided with a number of first limiting grooves, which are arranged opposite to a number of fixing holes.

[0016] As a further technical solution, in the connected state, a deformation space is formed between the limiting part and the connecting part.

[0017] As a further technical solution, a sidewall is formed between the contact surface and the mounting surface of the lamp housing, and a number of second limiting grooves are provided on the sidewall, which are arranged opposite to a number of fixing holes.

[0018] As a further technical solution, the inner wall of the installation space is inclined, and the size of the light source board is smaller than the size of the bottom of the installation space.

[0019] The technical solution of this utility model places the light source board within the installation space of the lamp housing and creates a sealing groove on the lamp housing, placing the sealing ring within the sealing groove. After being connected to the face cover via several first connectors, the lampshade is pressed between the contact surface of the lamp housing and the face cover, and the lampshade presses down on the sealing ring. Under the action of the several first connectors, the lampshade is always kept in close contact with the contact surface, thereby pressing the sealing ring. Since the sealing ring is always in a compressed state, it fills the sealing groove and seals the contact surface between the lampshade and the lamp housing. Compared with the prior art, when manufacturing the lamp body, there is no need to apply glue. The internal sealing of the lamp body is achieved directly through structural changes and the use of the sealing ring. After sealing, since the sealing ring is always in a compressed state, the finished lamp body can meet the IP67 protection level. This further reduces the difficulty of lamp body manufacturing while improving the efficiency of lamp body manufacturing. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-2 As shown, the lamp body of the IP67 protection-rated explosion-proof double-headed lamp proposed in this utility model includes:

[0030] The lamp housing 1 and the light source plate 2 disposed within the lamp housing 1 form an installation space 3, with the light source plate 2 positioned at the bottom of the installation space 3. During use, the lamp housing 1 connects to the dual-head lamp body, supplying the light source plate 2 with the electrical energy required for illumination. Specifically, the light source plate 2 has an interface that allows connection to wires on the dual-head lamp body. Figure 1 As shown, a number of LED beads 21 are arranged on the light source plate 2 in a regular pattern; specifically, the LED beads 21 are arranged in a ring with the center point of the light source plate 2 as the center. In this utility model, the light source plate 2 is circular, so the center point is the center, and the LED beads 21 are arranged in a ring with the center point as the center. It should be noted that the inner wall of the installation space 3 is inclined, and the size of the light source plate 2 is smaller than the size of the bottom of the installation space 3; this ensures that there is enough space to operate the light source plate 2 within the installation space 3, thereby enabling better assembly and disassembly of the light source plate 2.

[0031] In addition, the light source plate 2 is provided with a plurality of mounting holes 22, and a plurality of second connectors 82 pass through the plurality of mounting holes 22 to fix the light source plate 2 to the bottom of the mounting space 3. It should be further noted that a plurality of threaded holes are provided at the bottom of the mounting space 3, and the number of threaded holes is the same as the number of second connectors 82 and mounting holes 22. When fixing, the second connectors 82 pass through the light source plate 2 and connect with the threaded holes to achieve fixing of the light source plate 2. Preferably, the light source plate 2 is provided with two mounting holes 22, and the bottom of the mounting space 3 is provided with two threaded holes. The two second connectors 82 pass through the two mounting holes 22 respectively and connect with the two threaded holes. In this utility model, the second connectors 82 are preferably bolts.

[0032] like Figure 2As shown, the sealing groove 4 is formed around the installation space 3. A sealing ring 5 is provided in the sealing groove 4, and the diameter of the sealing ring 5 is greater than the depth of the sealing groove 4. The lampshade 6 and the face cover 7 are sequentially arranged on the lamp housing 1 and are fixed to the face cover 7 by several first connectors 81 passing through the lamp housing 1. After fixing, the lampshade 6 is restricted between the contact surface 11 of the lamp housing 1 and the face cover 7, and the lampshade 6 squeezes the sealing ring 5 after contacting it. Specifically, the sealing groove 4 is formed on the contact surface 11 of the lamp housing 1. When the lampshade 6 and the face cover 7 are installed, the sealing ring 5 is placed in the sealing groove 4. Since the diameter of the sealing ring 5 is greater than the depth of the sealing groove 4, a part of the sealing ring 5 will protrude from the sealing groove 4 and be placed above the contact surface 11. When the lampshade 6 and the face cover 7 are fixed by the first connectors 81, the lampshade 6 will apply force to the sealing ring 5, and the sealing ring 5 will be squeezed and deformed. Part of it will fill the sealing groove 4, and the other part will be placed between the lampshade 6 and the contact surface 11 to seal.

[0033] like Figure 1 and 2 As shown, the outer edge of the lamp housing 1 is provided with a mounting surface 12 that is lower than the contact surface 11 of the lamp housing 1. The mounting surface 12 is provided with a plurality of fixing holes 13, and a plurality of first connectors 81 are inserted into the plurality of fixing holes 13. The mounting surface 12 forms a stepped shape between the contact surface 11 and the mounting surface 12. After the plurality of first connectors 81 pass through the plurality of fixing holes 13 and are connected to the cover 7, a part of the cover 7 will be placed on the mounting surface 12 and limited by the stepped shape between the mounting surface 12 and the contact surface 11. On the one hand, this can ensure the accuracy of the cover 7 during installation, and on the other hand, it can seal the cover 7 by cooperating with the mounting surface 12. Of course, to increase the sealing effect, a sealing layer (not shown in the figure) can be added between the cover 7 and the mounting surface 12. The sealing layer can increase the sealing effect between the cover 7 and the mounting surface 12. Preferably, the added sealing layer is a rubber layer.

[0034] like Figure 2 and Figure 3 As shown, the cover 7 includes a connecting part 71 and a pressing part 72. The outer edge of the connecting part 71 is adapted to the outer surface of the lamp housing 1, and the pressing part 72 is disposed on the inner surface of the connecting part 71. Specifically, a plurality of first connecting members 81 pass through the fixing holes 13 and are connected to the connecting part 71. The connecting part 71 is sealed by contacting the mounting surface 12. When the connecting part 71 is fixed by the first connecting members 81, its outer surface is on the same plane as the outer surface of the lamp housing 1. In this utility model, it is preferable to open four fixing holes 13 on the mounting surface 12, and use four first connecting members 81 to pass through the four fixing holes 13 respectively and connect to the connecting part 71. Specifically, the first connecting members 81 are bolts, which pass through the four fixing holes 13 respectively and are threadedly connected to the connecting part 71. Figure 2As shown, the outer edge of the pressing part 72 is connected to the connecting part 71, and after connection, the top surface of the pressing part 72 and the top surface of the connecting part 71 are on the same horizontal plane. In this utility model, the connecting part 71 and the pressing part 72 are preferably integrally formed. In the connected state, the pressing part 72 contacts the lampshade 6 to press the lampshade 6. It should be noted that the structure of the contact position between the pressing part 72 and the lampshade 6 is adapted to ensure that the lampshade 6 will not be damaged during pressing.

[0035] In addition, in this utility model, the lampshade 6 includes a limiting part 61 and a cover body 62, the cover body 62 being disposed on the limiting part 61; in the connected state, the limiting part 61 is positioned between the mounting surface 12 of the lamp housing 1 and the pressing part 72. In actual use, the lampshade 6 protects the light source plate 2 on the one hand, and changes the direction of light emitted from the light source plate 2 as needed on the other hand. Specifically, it uses a light-transmitting plate from the prior art, which is not further limited in this respect; such as Figure 2 As shown, after the faceplate 7 is fixed by the first connector 81, the faceplate 7 presses against the limiting part 61, and the limiting part 61 presses against the sealing ring 5, causing the sealing ring 5 to deform; as Figure 3 As shown; due to the heat generated by the light source board 2 during use or the temperature of the operating area rising, the lampshade 6 will deform as the temperature rises. Therefore, in the connected state, a deformation space 9 is formed between the limiting part 61 and the connecting part 71. In this way, there is enough space to adapt to the deformation of the limiting part 61 as the temperature changes, avoiding damage to the lampshade 6 due to deformation caused by the lack of a working space.

[0036] like Figure 1 As shown, the limiting part 61 is provided with a plurality of first limiting grooves 63, which are arranged opposite to a plurality of fixing holes 13; a side wall 14 is formed between the contact surface 11 and the mounting surface 12 of the lamp housing 1, and a plurality of second limiting grooves 15 are provided on the side wall 14, which are arranged opposite to a plurality of fixing holes 13; by setting the first limiting grooves 63 and the second limiting grooves 15, on the one hand, the lamp cover 6 can be prevented from rotating in the installation state; on the other hand, during installation, the first limiting grooves 63 and the second limiting grooves 15 can be used as reference points to ensure accurate and fast installation and improve the overall installation efficiency.

[0037] The technical solution of this utility model places the light source plate 2 in the installation space 3 of the lamp housing 1, and opens a sealing groove 4 on the lamp housing 1 so that the sealing ring 5 is placed in the sealing groove 4. After being connected to the face cover 7 by several first connectors 81, the lamp cover 6 is pressed between the contact surface 11 of the lamp housing 1 and the face cover 7, and the sealing ring 5 is pressed by the lamp cover 6. Under the action of several first connectors 81, the lamp cover 6 is always in close contact with the contact surface 11, and the sealing ring 5 is pressed by the lamp cover 6. Since the sealing ring 5 is always in a compressed state, it will fill the sealing groove 4 and seal the contact surface 11 between the lamp cover 6 and the lamp housing 1. Compared with the prior art, when manufacturing the lamp body, there is no need to apply glue. The internal sealing of the lamp body is achieved directly by changing the structure and cooperating with the sealing ring 5. After sealing, since the sealing ring 5 is always in a compressed state, the finished lamp body can meet the IP67 protection level. This further reduces the difficulty of lamp body manufacturing and improves the efficiency of lamp body manufacturing.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
