[0026] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Please refer to Figures 1 to 5 , Figure 1 A schematic structural diagram of an embodiment of a lamp device provided in the present application; Figure 2 for Figure 1 an exploded view of the lamp assembly shown; Figure 3 for Figure 2 A structural schematic diagram of the middle cover from another perspective; Figure 4 for Figure 2 Schematic diagram of the structure of the middle sealing ring; Figure 5 for Figure 2 Schematic diagram of the structure of the middle sealing plug.

[0028] In this embodiment, the lamp device includes a box body 10 and a cover plate 20. The top of the box body 10 is open. The cover plate 20 is used to seal the open top of the box body 10. The cover plate 20 and the box body 10 are fixedly connected to form a relatively closed space between the cover plate 20 and the box body 10, and the lamp body and related accessories can be installed in the space.

[0029] Specifically, a lamp installation position 16 for installing the lamp body is provided in the box body 10, and a lamp limiting portion 22 is correspondingly provided on the cover plate 20. The box body 10 can be sealed and installed with a transparent plate (such as glass) at the lamp installation position 16 to facilitate the light of the lamp body to be irradiated out through the transparent plate.

[0030] The cover plate 20 has an annular convex rib 21 on one side facing the box body 10 .

[0031] The side wall of the box body 10 has a receiving groove 12 opening toward the cover plate 20 , and the receiving groove 12 is communicated with the inner cavity of the box body 10 .

[0032] The lamp device also includes a wire 30, one end of which can extend into the box body 10 through the accommodating groove 12 to be electrically connected to the lamp body in the box body 10, and the other end of the wire 30 is located outside the box body 10 and can be connected to an external power supply or other devices electrically connected to the lamp body.

[0033] The conductive wire 30 is covered with a sealing ring 40 , which can be sealed with the box body 10 and the cover plate 20 at the location of the receiving groove 12 to ensure the waterproofness and sealing effect of the lamp device.

[0034] Specifically, at least part of the sealing ring 40 is located in the accommodating groove 12, and the top of the sealing ring 40, that is, the side of the sealing ring 40 facing the cover plate 20 has a second groove 411, and the annular rib 21 on the cover plate 20 is plugged into and matched with the first groove 11 and the second groove 411.

[0035] In this way, a second groove 411 is set on the sealing ring 40, which cooperates with the first groove 11 on the top wall of the box body 10 and the convex rib 21 on the cover plate 20, so as to avoid the convex rib 21 on the cover plate 20 from being disconnected at the position of the accommodating groove 12. In this way, deformation problems such as shrinkage or distortion caused by the discontinuity of the convex rib 21 on the cover plate 20 during processing are avoided, and the processing quality of the cover plate 20 can be improved, thereby improving the sealing between the cover plate 20 and the box body 10.

[0036] In this embodiment, the side wall of the box body 10 also has a receiving groove 13 with an opening toward the cover plate 20, and the receiving groove 13 is connected to the inner cavity of the box body 10. The lamp device also includes a sealing plug 50, which is used to seal the receiving groove 13. At least a part of the sealing plug 50 is located in the receiving groove 13. The top of the sealing plug 50, that is, the top of the sealing plug 50 facing the cover plate 20 has a third groove 511, and the third groove 511 is also plugged into and matched with the rib 21 of the cover plate 20.

[0037] The arrangement of the receiving groove 13 can facilitate the connection of the lamp device with another lamp to form a lamp group.

[0038] In the illustrated example, the box body 10 is provided with only one receiving groove 12 and one receiving groove 13, and the receiving groove 12 and the receiving groove 13 are located on the same side wall of the box body 10. After the sealing ring 40 is placed in the receiving groove 12 and the sealing plug 50 is placed in the receiving groove 13, the first groove 11 of the box body 10, the second groove 411 of the sealing ring 40 and the third groove 511 of the sealing plug 50 are connected to form an annular groove matching the annular rib 21 of the cover plate 20. After the cover plate 20 is matched with the box body 10, the annular rib 21 is inserted into the annular groove, which can ensure the sealing effect of the cover plate 20 and the box body 10.

[0039] Exemplarily, the cover plate 20 is an injection molded part, and the convex rib 21 on the cover plate 20 is a ring-shaped closed structure. In this way, the structure of the cover plate 20 is relatively uniform, the deformation during injection molding is small, the molding quality can be guaranteed, and it is conducive to the subsequent fixed connection with the box body 10.

[0040] Generally speaking, one receiving slot 12 and one containing slot 13 provided on the box body 10 can meet the requirements of the lamp device in practical applications. In other implementations, the number of containing slots 12 and containing slots 13 can also be set according to specific requirements.

[0041] When the lamp device is used independently, the accommodating groove 13 may not be provided, and only the accommodating groove 12 is provided. In this case, the first groove 11 of the box body 10 and the second groove 411 of the sealing ring 40 located in the accommodating groove 12 together form an annular groove matching the annular rib 21.

[0042] In one implementation, the sealing ring 40 has a through hole portion 43 for the wire 30 to pass through, and the hole wall of the through hole portion 43 has an annular protrusion 431, which is conducive to increasing the interference fit between the wire 30 and the through hole portion 43, thereby ensuring the sealing between the wire 30 and the sealing ring 40.

[0043] A plurality of annular protrusions 431 may be provided on the hole wall of the through hole portion 43 , and the plurality of annular protrusions 431 are arranged along the axial direction of the through hole portion 43 .

[0044] In one implementation, the sealing ring 40 includes a first ring portion 41, the first ring portion 41 is located in the accommodating groove 12, the first ring portion 41 is interference fit with the corresponding parts of the accommodating groove 12 and the cover plate 20, the second groove 411 plug-fitted with the rib 21 of the cover plate 20 is provided in the first ring portion 41, and the outer peripheral wall of the first ring portion 41 has a first annular protrusion 412. It can be understood that part of the first annular protrusion 412 is located at the bottom wall of the second groove 411, and the setting of the first annular protrusion 412 can be Increase the interference fit amount, so that after the cover plate 20 is fixedly connected to the box body 10, the rib 21 of the cover plate 20 is inserted into the second groove 411, and can be pressed against the first circle portion 41 in the direction of the box body 10. The outer peripheral wall of the first circle portion 41 cooperates with the groove wall of the accommodating groove 12 and the cover plate 20. Under the action of the first annular protrusion 412, the sealing effect can be ensured. Combined with the sealing cooperation of the wire 30 and the through-hole portion 43, the sealing effect of the box body 10 and the cover plate 20 at the position of the accommodating groove 12 can be guaranteed after assembly.

[0045] Furthermore, the sealing ring 40 also includes a second ring portion 42, which is integrally formed with the first ring portion 41. The interior of the box body 10 also includes a first mounting groove 14 connected to the receiving groove 12. The second ring portion 42 is located in the first mounting groove 14. The second ring portion 42 is interference-fitted with the corresponding parts of the first mounting groove 14 and the cover plate 20. The outer peripheral wall of the second ring portion 42 includes a second annular protrusion 421. The provision of the second annular protrusion 421 can increase the amount of interference fit. In this way, a part of the sealing ring 40 is interference-fitted with the receiving groove 12 and the cover plate 20 at the side wall of the box body 10, and the other part is still interference-fitted with the box body 10 and the cover plate 20 after extending into the box body 10, which can improve the sealing effect.

[0046] In actual configuration, the number and specific structure of the first annular protrusion 412 and the second annular protrusion 421 can be adjusted as required. Figure 4 In the example shown, the first ring portion 41 is provided with a first annular protrusion 412 , and the second ring portion 42 is provided with two second annular protrusions 421 .

[0047] In one implementation, the sealing plug 50 includes a first plug portion 51, the first plug portion 51 is located in the receiving groove 13, the first plug portion 51 is interference fit with the corresponding parts of the receiving groove 13 and the cover plate 20, the third groove 511 plug-fitted with the rib 21 of the cover plate 20 is provided on the first plug portion 51, and the outer peripheral wall of the first plug portion 51 has a third annular protrusion 512. It can be understood that part of the third annular protrusion 512 is located on the bottom wall of the third groove 511, and the third annular protrusion 512 is located on the bottom wall of the third groove 511. The setting of the protrusion 512 can increase the amount of interference fit. In this way, after the cover plate 20 is fixedly connected to the box body 10, the rib 21 of the cover plate 20 is inserted into the third groove 511, which can press the first plug portion 51 in the direction of the box body 10. The outer peripheral wall of the first plug portion 51 cooperates with the groove wall of the receiving groove 13 and the cover plate 20. Under the action of the third annular protrusion 512, the sealing effect can be ensured. After assembly, the sealing effect of the box body 10 and the cover plate 20 at the position of the receiving groove 13 can be guaranteed.

[0048] Furthermore, the sealing plug 50 also includes a second plug portion 52, which is integrally formed with the first plug portion 51. The interior of the box body 10 also includes a second mounting groove 15 connected to the receiving groove 13. The second plug portion 52 is located in the second mounting groove 15. The second plug portion 52 is interference-fitted with the corresponding parts of the second mounting groove 15 and the cover plate 20. The outer peripheral wall of the second plug portion 52 includes a fourth annular protrusion 521. The provision of the fourth annular protrusion 521 can increase the amount of interference fit. In this way, a part of the sealing plug 50 is interference-fitted with the receiving groove 13 and the cover plate 20 at the side wall of the box body 10, and the other part is still interference-fitted with the box body 10 and the cover plate 20 after extending into the box body 10, which can improve the sealing effect.

[0049] In actual configuration, the number and specific structure of the third annular protrusion 512 and the fourth annular protrusion 521 can be adjusted as required. Figure 5 In the example shown, the first plug portion 51 is provided with a third annular protrusion 512 , and the second plug portion 52 is provided with two fourth annular protrusions 521 .

[0050] contrast Figure 4 and Figure 5 The appearance structures of the sealing ring 40 and the sealing plug 50 can be consistent. The only difference between the two is that the sealing ring 40 has a through hole portion 43 that cooperates with the wire 30, and the sealing plug 50 does not have a through hole portion. In this way, when the lamp device is connected to another lamp, the sealing plug 50 is removed, and the other wire can be directly installed in the receiving groove 13 of the box body 10 after cooperating with the other sealing ring. That is, the other sealing ring that is sleeved with the other wire can directly replace the sealing plug 50 to realize the connection between the lamp body in the lamp device and the other lamp. In this way, the sealing ring 40 and the sealing plug 50 can be designed in a unified manner to reduce costs.

[0051] In one practicable manner, the cover plate 20 and the box body 10 can be fixed by ultrasonic welding. The structural design of the cover plate 20 can better control the deformation of the cover plate 20, so that it can be better welded during ultrasonic welding, and more accurately cooperate and position with the sealing ring 40 and the sealing plug 50 to improve the reliability of the sealing and waterproof performance.

[0052] Exemplarily, the lamp device may be an ultraviolet lamp.
