[0033] like Figure 1 As shown, the base 11 includes a base 111 located at the top, and the base 111 extends outward along the outer wall of the upper end of the base 11 to form a circular ring structure. A countersunk hole 1112 is provided at the upper end of the base 111, and the countersunk hole 1112 extends downward along the upper end surface of the base 111. A lampshade plate 14 is provided in the countersunk hole 1112. The lampshade plate 14 is a disc structure, and the bottom surface of the lampshade plate 14 is in contact with the bottom surface of the countersunk hole 1112, and the outer peripheral wall of the lampshade plate 14 is in contact with the inner peripheral wall of the countersunk hole 1112 and is sealed by glue.
[0034] like Figure 2 As shown, an annular groove 1111 is arranged on the outer side of the upper end of the countersunk hole 1112 , and the annular groove 1111 extends outward along the inner wall of the countersunk hole 1112 to form an annular structure, and a sealing ring 3 15 is arranged in the annular groove 1111 .
[0035] The lower end of the cover plate 12 is inserted into the outer wall of the base 111. The cover plate 12 includes a top plate 121 at the top, and the lower end surface of the top plate 121 is arranged in close contact with the upper end surface of the base 111. The lower end surface of the top plate 121 and the upper end surface of the base 111 press the sealing ring 3 15 up and down to form a sealing effect.
[0036] The top plate 121 is provided with a light hole 1211, which penetrates vertically along the axis of the top plate 121, and is located above the lampshade plate 14. Light passing through the lampshade plate 14 is emitted from the light hole 1211. The inner diameter of the light hole 1211 is smaller than the outer diameter of the lampshade plate 14, so that the top plate 121 forms a limit above the lampshade plate 14 to prevent the lampshade plate 14 from falling out, and the lampshade plate 14 forms a seal on the upper end of the base 11.
[0037] like Figure 2 As shown, a plurality of mounting holes 1115 are provided on the upper end surface of the base 111 . The mounting holes 1115 extend downward along the upper end surface of the base 111 . The mounting holes 1115 are countersunk holes. There are eight mounting holes 1115 evenly distributed along the circumference of the base 111 .
[0038] like Figure 2 As shown, the mounting hole 1115 is installed with a connecting component 2, and the connecting component 2 includes an insert block 21, and the insert block 21 passes through the top plate 121 and is threadedly inserted into the mounting hole 1115, so that the cover plate 12 and the base 11 are fixed up and down.
[0039] like Figure 2 As shown, the plug block 21 is provided with a through hole 211, which axially penetrates the plug block 21, and a sealing plug 22 is installed on the top of the plug block 21, and the sealing plug 22 is inserted into the top of the through hole 211 to form a seal.
[0040] like Figure 2 As shown, a slider 24 is installed in a sliding connection in the through hole 211, and the slider 24 includes a base plate 241 and an extension plate 242 located above the base plate 241. The outer peripheral wall of the extension plate 242 can fit with the inner peripheral wall of the through hole 211 and can move up and down along the inner wall of the through hole 211. The extension plate 242 can slide out of the bottom end of the through hole 211 when it moves downward.
[0041] like Figure 2 As shown, the bottom plate 241 can move up and down along the inner wall of the mounting hole 1115, and this part of the mounting hole 1115 is a light hole.
[0042] like Figure 2As shown, a sealing ring 23 is bonded to the bottom of the plug block 21, and the upper end surface of the sealing ring 23 is in contact with the bottom surface of the plug block 21. A spring 25 is provided at the bottom of the mounting hole 1115, and the upper end of the spring 25 abuts against the bottom plate 241 to insert the extension plate 242 into the through hole 211, and the upper end surface of the bottom plate 241 is in contact with the lower end surface of the sealing ring 23 to form a seal.
[0043] A conical hole 1113 is provided below the countersunk hole 1112, and the conical hole 1113 is located below the lampshade plate 14. A flow channel hole 1114 is punched perpendicular to the inner wall of the conical surface of the conical hole 1113, and the outer side of the flow channel hole 1114 extends to communicate with the bottom side wall of the mounting hole 1115.
[0044] A side groove 2411 is formed on one side of the bottom plate 241 . The side groove 2411 is connected vertically and communicates with the flow channel hole 1114 through the mounting hole 1115 .
[0045] like Figure 5 , Figure 6 , Figure 7 As shown, a lamp processing device is mainly used to process the flow channel hole 1114 of the above lamp, including a base 5, a motor 6 is installed on one side of the base 5, and a positioning block 51 is installed on the other side. The output shaft of the motor 6 passes through the base 5 and is connected to the positioning block 51. The motor 6 can drive the positioning block 51 to rotate. Figure 5 As shown, the positioning block 51 is provided with a positioning hole 511, and the positioning hole 511 is a countersunk hole. The base 11 to be processed is inserted into the positioning hole 511 to form a positioning. An extension hole 5111 is also provided at the bottom of the positioning hole 511, so that after the base 11 is inserted into the positioning hole 511, the contact surface with the positioning hole 511 is mainly the outer circle of the bottom surface of the base 11. By reducing the positioning method of the contact surface, the base 11 can be easily laid flat.
[0046] like Figure 5 As shown, a cylinder 7 is arranged on the side of the positioning block 51 away from the base 5, a connecting plate 71 is installed at the output end of the cylinder 7, and a pressure ring 9 is connected to the outer side of the connecting plate 71 through a bearing. Figure 7 As shown, the pressure ring 9 includes a ring 1 91 and a ring 2 92 located on both sides, and both rings 1 91 and 92 are complete circular ring structures. The pressure ring 9 also includes a ring 3 93 located between the rings 1 91 and 92, and the ring 3 93 is a semicircular ring with an opening formed on one side.
[0047] like Figure 5 , Figure 6 As shown, the output shaft of the cylinder 7 is pushed out to drive the second ring 92 of the pressure ring 9 to press the top end surface of the base 11 located in the positioning hole 511. A drilling machine 8 is arranged above the opening of the third ring 93. The drilling machine 8 includes a drill bit 81 located at the bottom. The drill bit 81 moves downward and contacts the top end surface of the base 11 located in the positioning hole 511. Figure 5The mounting hole 1115 at the bottom of the base 11 at the position shown forms a drilling operation, and the mounting hole 1115 is arranged perpendicular to the inner wall surface of the tapered hole 1113 to facilitate the drill bit 81 to drill holes and prevent it from slipping easily during drilling.
[0048] When a mounting hole 1115 is drilled, the motor 6 drives the positioning block 51 to rotate so that the position to be drilled is at the lowest position. During the rotation of the positioning block 51, the output shaft of the cylinder 7 remains in the supported state, and the pressure ring 9, the base 11, and the positioning block 51 are pressed against each other and rotate together. Through one clamping and positioning, the drilling operation of eight holes is completed, so that the accuracy of hole processing is improved and large errors caused by multiple clamping are avoided.
[0049] The air tightness testing method of the above lamps is:
[0050] ① Place the lamp in water, with the upper end surface of the cover plate 12 below the liquid level.
[0051] ② If Figure 2 As shown, the sealing plug 22 is removed from the through hole 211. Figure 4 As shown, the auxiliary rod 3 is inserted into the through hole 211, and the auxiliary rod 3 includes a pressing plate 32 and an extension rod 1 33 located below the pressing plate 32. The extension rod 1 33 is threadedly connected and inserted into the through hole 211. The bottom of the extension rod 1 33 extends downward to form an extension rod 2 331, and the outer diameter of the extension rod 2 331 is smaller than the through hole 211. The auxiliary rod 3 is provided with a countersunk hole 2 31, which extends downward from the top of the auxiliary rod 3, and the lower part of the countersunk hole 2 31 is connected to a side hole 3311.
[0052] A sealing ring 24 is provided under the pressure plate 32. The sealing ring 24 is a sealing ring with a large degree of deformability. When the auxiliary rod 3 is inserted, the bottom of the extension rod 231 presses downward against the extension plate 242 and pushes the slider 24 to move downward. When the sealing ring 24 is just beginning to be compressed, the extension plate 242 just leaves the bottom of the plug 21. At this time, the countersunk hole 231, the side hole 3311, the through hole 211, the side groove 2411, and the flow channel hole 1114 are connected.
[0053] ③ Gas is introduced into the top of the second countersunk hole 31, and the gas enters the base 11. Observe whether there are bubbles at each contact position between the lamp and the water to determine whether there is leakage.
[0054] ④ After the detection is completed, the auxiliary rod 3 is taken out upwards.
[0055] Before the compression state of the sealing ring 24 is released, the extension plate 242 is inserted into the bottom of the plug block 21 to form a seal between the plug block 21 and the extension plate 242. The purpose of this arrangement is to reduce the amount of air entering the base 11 when the auxiliary rod 3 is removed during the vacuuming of the base 11 by the auxiliary rod 3.
[0056] like Figure 4As shown, the inner diameter of the sealing ring 1 23 is larger than the through hole 211 , so that when the extension plate 242 just leaves the bottom of the through hole 211 downward, the countersunk hole 2 31 is immediately connected with the cavity in the base 11 .
[0057] The side groove 2411 is recessed and extends inwardly along the outer wall of the bottom plate 241 . The width of the side groove 2411 is set to be smaller than the cross-sectional width of the sealing ring 23 , so that when the bottom plate 241 and the sealing ring 23 are tightly attached up and down, no leakage occurs.
[0058] 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, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
