New Description: [New Technology Field] This creation is about a type of lamp structure, especially a lamp structure that is simple in structure, can be effectively and conveniently assembled, and reduces production costs. [Prior Art] The structure of the headlights is more than 4's, especially regarding the use of the lights in the locomotive field, including the main lights used in front of the front of the car and the directional lights used on both sides of the front and rear sides of the car; The types of the labels may vary, but the construction is usually similar. The following is an example of the main light used in front of the Harley-brand heavy-duty locomotive, but it is not limited to the Harley brand or the main light in front of the front. The main lamp structure in front of the conventional vehicle head is usually a lampshade, and a lamp socket is arranged on the front opening of the lamp holder to be positioned by the screw ring. Generally, the ring is screwed to the inner edge of the front opening of the lampshade. The internal thread is formed. Since the lamp cover and the rotating ring are only thin and thin, it is conceivable that both the internal thread and the external thread have a very fine thread pitch. Such a thread structure is easy to cause plating difficulties. However, the quality problem of the uniformity of the thickness of the plating layer occurs at the same time, and at the same time, due to the screwing manner of the internal thread and the external thread, it is easy to cause the uneven plating layer to be damaged when the screw is set, and of course, the intended borrowing key is lost. The way to improve the texture and anti-rust function, it needs further improvement. [New content] The present invention provides a lampshade, which is hollow inside and has a closed end and an open end; an accommodating area is arranged inside the open end; a lamp holder, one end M351983 is a seat cover, and the other end is provided with a transparent lamp a curtain, wherein a bulb is disposed inside; an inner ring seat is accommodated in the accommodating area of the lampshade; a ring-shaped seat is radially extended on one side toward the center of the ring; and an outer ring cover has a portion of the outer diameter can be received in the inner portion of the inner ring seat; the seat cover of the lamp holder extends through the inner ring seat, and the lamp holder is sandwiched between the inner ring seat and the outer ring cover The inserting portion is integrally formed, and is integrally fixed to the accommodating area inside the open end of the lampshade. [Embodiment] Please refer to the first and second figures. The present embodiment includes: a lampshade 1 having a hollow interior, a tapered end 11 1 and a circular open end 1 2; the open end of the lampshade 1 The inner side of the inner surface of the cover 1 is formed with a first inner shoulder portion 14 having a larger inner diameter, and a first shoulder portion 14 is formed on the inner side due to the difference in inner diameter; a plurality of first fixing holes 15 having a pupil shape; a lamp holder 2 having a circular shape, one end being a seat cover 2 1, and the other end being provided with a transparent light curtain 22, the outer periphery of which has an outer diameter compared with the seat cover 2 a slightly larger rim 23, a bulb 2 (not shown) is disposed inside the socket 2 between the seat cover 21 and the transparent lampshade 2; an inner ring seat 3 is annular and can be accommodated In the accommodating area 13 of the lampshade; a plurality of boring-shaped second fixing holes 31 are radially equally spaced around the circumference; the inner ring seat 3 is radially extended at one side toward the center of the ring. a plurality of third fixing holes 33 respectively provided with internal threads corresponding to the first fixing holes 15 of the lampshade 1; the seat 3 3 is provided on the outer circumference of the inner ring seat 3 at the seat 32 There are many axial a fourth fixing hole 3 4 having an internal thread; -5- M351983 an outer ring cover 4 which is annular and has a section of the outer diameter which can be accommodated in the inner diameter of the inner ring seat 3 41. The peripheral portion of the inserting portion 41 is equally divided into a plurality of screw-shaped fifth fixing holes 4 2; the outer ring cover 4 forms a second shoulder portion 43 and a third portion on the outer peripheral edge due to the difference in outer diameter. Shoulder 44. Referring to the third figure, in the assembly, the lamp holder 2 can be advanced through the seat cover 2 1 into the inner ring seat 3 ring, and the abutment edge 2 3 can be accommodated in the ring seat 3 2 front; The outer ring cover 4 embedding portion 4 1 is embedded in the inner diameter of the inner ring seat 3, and the plurality of first screwing elements 5 are screwed on the outer ring through a plurality of second hole-shaped fixing holes 31 of the inner ring seat 3 The cover 4 has a plurality of screw-shaped fifth fixing holes 42 corresponding thereto, so that the inner ring seat 3 and the outer ring cover 4 are integrated into one body, and the upper edge 2 3 of the lamp holder 2 is accommodated in the inner ring seat 3 The seat 32 is interposed between the outer ring cover 4 and the outer ring cover 4; and the plurality of second screwing elements 6 are screwed to the socket 2 by a plurality of fourth fixing holes 34 having internal threads provided by the inner ring seat 3 in the axial direction. The rim 2 3 is thereby used to achieve a stable positioning of the socket 2 . After the inner ring seat 3, the lamp holder 2 and the outer ring cover 4 are integrally combined, the whole body is embedded in the lamp cover 1, as shown in the fourth, fifth and sixth figures, so that the inner ring seat 3 is seated against the seat 3 2 The first shoulder portion 14; and the plurality of third screwing members 7 are screwed to the inner ring seat 3 of the inner ring seat 3 by a plurality of first pin-shaped first fixing holes 15 The fixing hole 3 3 ; thus completes the assembly work of the entire lamp as shown in the seventh figure. In the design of the present embodiment, since the internal thread is not provided on the inner diameter of the accommodating area 13 of the lampshade 1, it is possible to avoid the difficulty of conventional plating, and the quality problem of the uniformity of the thickness of the plating layer occurs therein; The combination of the ring seat 3, the lamp holder 2 and the outer ring cover 4 is not screwed to the external thread and the external screw of the M351983 lamp cover 1, so that the uneven plating layer may be damaged when the screw is not provided. On the other hand, since the inner ring seat 3 and the lamp holder 2 are integrated with the outer ring cover 4 and then combined with the lamp cover 1, although four elements are combined, it is already an integral component when combined with the lamp cover 1. Therefore, it is quite convenient to assemble, and it is less likely to damage the plating layer on the inner diameter of the housing area of the lampshade 1 . However, the above is only a preferred and feasible embodiment of the present invention, and the scope of the present invention cannot be limited by this, that is, the equivalent structural changes and modifications made by the applicant in accordance with the scope of the patent application and the content of the creation specification. All should remain within the scope of this creation patent. BRIEF DESCRIPTION OF THE DRAWINGS The first figure shows an exploded view of the present embodiment.
