Technical Field

[0001] This invention relates to tri-proof lamp technology, and more particularly to a tri-proof lamp. Background Technology

[0002] The "three-proof" in tri-proof lights refers to waterproofing, dustproofing, and corrosion resistance. Tri-proof lights utilize specialized anti-oxidation and anti-corrosion materials and silicone sealing gaskets to meet the protection requirements of the lighting fixtures. Production workshops and similar environments have particularly high requirements for the cleanliness of the surrounding environment; therefore, they also have special requirements for the lighting used within these workshops.

[0003] CN115405877A discloses a modular, quick-disassembly, and replaceable tri-proof lamp. The sealing method used by this tri-proof lamp is to use a sealing ring. By placing the sealing ring in the sealing ring groove inside the waterproof connector, the sealing ring can only achieve a seal at one location, making it difficult to achieve a complete seal at different locations. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes a tri-proof lamp.

[0005] The technical solution of this invention is implemented as follows:

[0006] A tri-proof light, characterized in that it comprises:

[0007] A light source, wherein the light source is disc-shaped;

[0008] A lamp holder has a cavity in the middle for holding a light source, the cavity having a stepped portion, and the edge of the lamp holder having an outwardly curved lip.

[0009] A lamp cover is mounted on a lamp holder and connected to the lamp holder by bolts. The lamp cover consists of a mounting body and a sealing body. The sealing body has a sealing chamber inside. The mounting body is connected to the lamp holder, and a sealing gap is formed between the lamp holder and the lamp cover.

[0010] A sealing element disposed in a sealed chamber, the sealing element being composed of a frustum and a cylinder;

[0011] A sealing ring is disposed between the lamp holder and the lamp cover, the sealing ring being positioned on a stepped portion. The sealing ring consists of a main body and a deformable portion that can be deformed under stress. The main body has a positioning hole, and the inner wall of the lamp cover has a positioning post that mates with the positioning hole. The deformable portion is located within the sealing gap.

[0012] A mounting component is disposed in the middle of a seal, the middle of which has a wire connected to the light source body. The lower end of the mounting component is connected to the light source body, and the upper end extends through the seal to the outside of the lamp cover.

[0013] In this invention, the frustum body has multiple sealing discs, and the sealing chamber has sealing disc grooves that cooperate with the sealing discs.

[0014] In this invention, the seal has an opening that penetrates the frustum and the cylinder.

[0015] In this invention, the lamp cover has an arc groove that mates with the arc lip, the inner wall of the arc groove has multiple serrated portions, the arc lip has multiple serrated grooves, and the deformable portion can wrap around the serrated portions and be squeezed into the serrated grooves after being subjected to extrusion pressure.

[0016] In this invention, the mounting body has a guide portion in the middle that applies force to the deformable portion, and the guide portion is adjacent to the arc groove.

[0017] In this invention, the inner wall of the mounting body has a pressing part that applies pressure to the main body, and the pressing part has an inclined pressing surface.

[0018] In this invention, the inner wall of the mounting body has a limiting post, the limiting post has an extension post, the light source body has a limiting sleeve that cooperates with the limiting post, and there is an movable gap between the limiting post and the limiting sleeve.

[0019] In this invention, the stepped portion has an arc-shaped groove, the sealing ring has an arc-shaped portion that mates with the arc-shaped groove, and the arc angle of the arc-shaped groove is an anomalous arc.

[0020] In this invention, the sealing ring also has a pressure-applying part, which is placed on the edge of the light source body.

[0021] In this invention, the mounting component consists of an extrusion disc and a sealing post. The connection between the extrusion disc and the sealing post has a conical surface. The extrusion disc is located at the lower end of the sealing component. The sealing post has a threaded portion that extends through the sealing component to the outside of the lamp cover. The threaded portion has a nut.

[0022] The tri-proof lamp of this invention has the following beneficial effects: It is not only compact and ingeniously designed, achieving waterproof, dustproof, and corrosion-resistant standards through a sealing ring between the lamp cover and the lamp holder, and a seal added at the point where the wires of the light source extend to the outside.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] like Figures 1 to 15 As shown, this tri-proof lamp of the present invention includes a light source 1, a lamp holder 2, a lamp cover 3, a sealing element 4, a sealing ring 5, and a mounting element 6. The light source 1 is a lamp fixture, connected to the mounting element 6 via a wire 7. The mounting element 6 is connected to the lamp cover 3 via bolts 8, which prevents stress on the connection between the wire 7 and the light source 1, reducing the pulling force exerted by the entire tri-proof lamp on the connection of the wire 7, and instead transferring the force entirely to the lamp cover 3. The lamp cover 3 is mounted on the lamp holder 2 and connected to it via bolts 8. The sealing element 4 seals the mounting element 6 and the lamp cover 3, while the sealing ring 5 seals the lamp cover 3 and the lamp holder 2.

[0041] The seal 4 can seal the wire 7 when it extends to the outside, thereby achieving partial sealing of the wire 7 when it passes through the lamp cover 3.

[0042] The sealing ring 5 maintains a seal between the lamp holder 2 and the lamp cover 3, achieving a first seal at the arc lip 9, a second seal at the stepped portion 10, and a third seal between the main body 11 and the positioning post 12. Furthermore, bolts 8 are used to connect the lamp holder 2, the lamp cover 3, and the sealing ring 5, ensuring that the lamp holder 2 and the lamp cover 3 cover the deformable portion 13, pressing the deformable portion 13 around the serrated portion 14 and into the serrated groove 15.

[0043] The light source 1 is disc-shaped, and its diameter matches the inner diameter of the receiving chamber 16 to keep the light source 1 in a fixed position. A limiting post 18 is located on the inner wall of the mounting body 17, and an extension post 19 is attached to the limiting post 18. The light source 1 has a limiting sleeve 20 that mates with the limiting post 18, and a movable gap 21 exists between the limiting post 18 and the limiting sleeve 20. Because the limiting post 18 has the extension post 19, and the limiting sleeve 20 has a hole in the middle for placing the extension post 19, the extension post 19 can be placed in the hole in the middle of the limiting sleeve 20. The limiting post 18 is placed on the limiting sleeve 20, and the length of the extension post 19 is less than the depth of the hole in the limiting sleeve 20, leaving a movable gap 21 between the extension post 19 and the hole in the limiting sleeve 20.

[0044] After the bolt 8 is tightened, the limiting post 18 and the limiting sleeve 20 come into contact. The limiting post 18 applies pressure to the limiting sleeve 20, thereby fixing the light source body 1. It can also work with the pressure applying part 22 to apply pressure to the light source body 1.

[0045] The lamp holder 2 has a cavity 16 in the middle for placing the light source 1. The cavity 16 has a stepped portion 10 with an arc-shaped groove 23. The sealing ring 5 has an arc-shaped portion 24 that mates with the arc-shaped groove 23. The arc angle of the arc-shaped groove 23 is a positive arc. When installing the sealing ring 5, the arc-shaped portion 24 is pressed into the arc-shaped groove 23, thereby fixing the sealing element 4 in the middle of the lamp holder 2.

[0046] The lamp holder 2 has an outwardly flared arc lip 9 on its edge, and the lamp cover 3 has an arc groove 25 that mates with the arc lip 9. The inner wall of the arc groove 25 has multiple serrated portions 14, and the arc lip 9 has multiple serrated grooves 15. After being subjected to compressive force, the deformable portion 13 can wrap around the serrated portions 14 and be squeezed into the serrated grooves 15.

[0047] The mounting body 17 has a guide portion 26 in the middle that applies force to the deformable part 13. The guide portion 26 is adjacent to the arc groove 25. When the lamp cover 3 covers the lamp holder 2, the positioning post 12 is aligned with the positioning hole 27, and the guide portion 26 is placed in the linear gap 28 between the main body 11 and the deformable part 13. The deformable part 13 deforms along the inner wall shape of the arc groove 25, so that the deformable part 13 is placed in the sealing gap 29, pressing the deformable part 13 between the lamp cover 3 and the lamp holder 2.

[0048] Meanwhile, the inner wall of the mounting body 17 has a pressing part 30 that applies pressure to the main body 11, and the pressing part 30 has an inclined pressing surface 31. The pressing surface 31 can press the edge of the main body 11, so that the main body 11 and the inner wall of the mounting body 17 are pressed and sealed.

[0049] The lamp cover 3 is connected to the lamp holder 2 by bolts 8. The lamp cover 3 consists of a mounting body 17 and a sealing body 32. The sealing body 32 has a sealing chamber 33 inside. The mounting body 17 is connected to the lamp holder 2, and a sealing gap 29 is formed between the lamp holder 2 and the lamp cover 3. The lamp cover 3 has heat dissipation fins 34.

[0050] A seal 4 is disposed in a sealing chamber 33. The seal 4 has a mounting hole 35 in the center for placing a mounting component 6. The seal 4 is composed of a frustum 36 and a cylinder 37. The seal 4 has an opening 38 that penetrates the frustum 36 and the cylinder 37, communicating with the mounting hole 35. The frustum 36 has multiple sealing discs 39, and the sealing chamber 33 has sealing disc grooves 40 that mate with the sealing discs 39.

[0051] Under normal conditions, the opening 38 of the seal 4 is open. When the seal 4 is placed in the sealing chamber 33, the inner diameter of the sealing chamber 33 is smaller than the diameter of the seal 4. When the opening 38 on the seal 4 is closed, the seal 4 can be placed in the sealing chamber 33 to achieve a seal.

[0052] Under normal conditions, the sealing ring 5 is in a close fit between the main body 11 and the deformable part 13, and the linear gap 28 is in a merged state.

[0053] Guided by the guide portion 26, the sealing ring 5 causes the deformable portion 13 to be placed in the sealing gap 29, so that the linear gap 28 is in an open state.

[0054] A sealing ring 5 is disposed between the lamp holder 2 and the lamp cover 3, and is positioned on the stepped portion 10. The sealing ring 5 consists of a main body portion 11 and a deformable portion 13 that can be deformed under force. A linear gap 28 is formed between the main body portion 11 and the deformable portion 13. The main body portion 11 has a positioning hole 27, and the inner wall of the lamp cover 3 has a positioning post 12 that mates with the positioning hole 27. The deformable portion 13 is located in the sealing gap 29.

[0055] The sealing ring 5 also has a pressure-applying part 22, which is placed on the edge of the light source body 1 to apply pressure and fix the edge of the light source body 1.

[0056] Mounting component 6 is disposed in the middle of sealing component 4. A wire 7 connected to the light source 1 is located in the middle of mounting component 6. The lower end of mounting component 6 is connected to the light source 1, and the upper end extends through sealing component 4 to the outside of lamp cover 3. Mounting component 6 consists of a pressing plate 41 and a sealing post 42. The connection between pressing plate 41 and sealing post 42 has a conical surface 43. Pressing plate 41 is located at the lower end of sealing component 4. Sealing post 42 has a threaded portion 44 that extends through sealing component 4 to the outside of lamp cover 3. A nut 45 is located on the threaded portion 44.

[0057] The wire 7 and the mounting part 6 are integrally formed, which can ensure that the wire 7 can be completely placed in the mounting part 6, and facilitate the connection between the mounting part 6 and the sealing part 4.

[0058] When fixing the mounting part 6, the seal 4 is inserted into the sealing chamber 33, and then the upper end of the mounting part 6 is inserted into the mounting hole 35 in the seal 4. The sealing post 42 compresses the mounting hole 35. This places the seal 4 in the sealing chamber 33, and the sealing disc 39 in the sealing disc groove 40. Then, the nut 45 is placed on the threaded part 44, and the nut 45 is rotated, causing the mounting part 6 to move upward. The conical surface 43 between the extrusion disc 41 and the sealing post 42 compresses the seal 4, causing the seal 4 to deform. Since the diameter of the sealing chamber 33 is smaller than the diameter of the seal 4, the opening 38 is closed after the seal 4 is installed in the sealing chamber 33. Therefore, when the mounting part 6 is placed in the mounting hole 35, the seal 4 is compressed into the sealing chamber 33, thereby fixing the mounting part 6 to the lamp cover 3.

[0059] The deformable portion 13 of the sealing ring 5 has an a-side and a b-side. The a-side contacts the inner wall of the arc groove 25, and the b-side contacts the surface of the arc lip 9. The a-side is pressed by the serrated portion 14 to form a serrated recess 46, while the b-side is pressed into the serrated groove 15 to form a serrated protrusion 47.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
