fig. 2 is a partial sectional structural schematic view of the present invention.

As shown in the figure:

the lamp comprises a base plate 1, a convex column 11, a limiting plate 12, a lampshade 2, a bulge 21, a positioning plate 22, a mounting seat 3, a first sliding groove 31, an outer shell 4, a plugboard 41, a sliding rod 42, an inner shell 5, a second sliding groove 51, a stop block 52 and a dustproof shell 6.

Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

As shown in fig. 1 and 2, a lamp cover coupling structure includes: chassis 1, lamp shade 2, a plurality of mount pads 3, shell 4 and inner shell 5.

The chassis 1 is provided with a plurality of hollow tubular convex columns 11 distributed along the circumferential direction of the chassis;

the lampshade 2 is arranged on the chassis 1, and the peripheral wall of the lampshade 2 is provided with a plurality of bulges 21 forming slots;

wherein, install a plurality of locating plates 22 in the slot, constitute the jack between locating plate 22 and the outer wall of lamp shade 2 and the arch 21 that is located this lamp shade 2 periphery, locating plate 22 and projection 11 are equal and one-to-one corresponding.

The mounting seats 3 are all mounted between the adjacent convex columns 11, the mounting seats 3 are clamped through the convex columns 11, and the mounting seats 3 are provided with first sliding grooves 31 along the circumferential direction;

the shell 4 is connected with the first sliding chute 31 on the mounting seat 3 and can move along the first sliding chute 31, and an inserting plate 41 is fixed on one side of the shell 4 close to the lampshade 2;

the inner shell 5 is sleeved in the outer shell 4 and connected with the mounting seat 3;

wherein, a cavity which is not contacted with each other is formed between the outer shell 4 and the inner shell 5.

Wherein, the inner peripheral wall of the outer shell 4 is fixed with a slide bar 42, and the outer shell 4 is connected with the inner shell 5 through the slide bar 42.

Correspondingly, the outer peripheral wall of the inner shell 5 is provided with a second sliding groove 51 along the length direction, one end of the sliding rod 42 departing from the outer shell 4 is arranged in the second sliding groove 51, and when the outer shell 4 moves along the first sliding groove 51, the sliding rod 42 moves along the second sliding groove 51.

The stoppers 52 for preventing the sliding rod 42 from falling off are installed at both ends of the second sliding groove 51, and the sliding rod 42 is installed in the cavity between the outer shell 4 and the inner shell 5, so that it is difficult for a user to visually identify the position of the sliding rod 42, the sliding rod 42 falls off when the outer shell 4 moves, which may affect the use effect, and the stoppers 52 may prevent the sliding rod 42 from falling off.

The inner pipe of the convex column 11 can be matched with the outer shell 4, specifically, the height of the outer shell 4 is smaller than that of the inner pipe of the convex column 11, so that the outer shell 4 can move between a butt joint position and a separation butt joint position with the inner pipe of the convex column 11.

Wherein, install a limiting plate 12 in the inner tube of projection 11 and separate this inner tube, the shell 4 of jack both sides can be followed first spout 31 and removed to projection 11 inner tube in, limiting plate 12 can prevent that the not inconsistent fixed effect that leads to unable reaching of displacement from appearing in both sides shell 4 when removing.

Wherein, set up all to set up the screw that link up each other on mount pad 3 and the chassis 1 to can dismantle the connection through the bolt, can conveniently change the damage part if damage appears in mount pad 3 or chassis 1, reduced the maintenance cost.

Wherein, chassis 1 and mount pad 3 all are surrounded by a dirt proof housing 6, and dirt proof housing 5 is connected with chassis 1's lateral wall, and the elastic sealing circle is arranged to 5 internal perisporium of dirt proof housing, and elastic sealing circle is cyclic annular and unanimous with 1 peripheral shape on chassis, and 1 joint in one side of elastic sealing circle on chassis often is difficult to the clearance to thin position part and influences fastening effect, adds the dirt proof ring and can prevent that the dust from getting into.

The specific operation flow is as follows:

firstly, when in use, the mounting base 3 is aligned to the vacant area between the adjacent convex columns 11 and clamped in the vacant area,

secondly, fixing the chassis 1 and the mounting seat 3 through bolts,

thirdly, poking the shell 4 on the mounting seats 3 at two sides of the convex column 11, moving the shell 4 into the inner pipe of the convex column 11 along the first sliding groove 31, moving the sliding rod 42 along the second sliding groove 51 when the shell 4 slides, moving the shell 4 to the position of the limiting plate 12 to stop, and inserting the inserting plate 41 which is integrally formed with the shell 4 into the inserting hole at the periphery of the lampshade 2 to be fixed when the shell 4 moves.

And fourthly, installing the dustproof shell 6, and clamping the chassis 1 on a sealing ring on the inner periphery of the dustproof shell 6 and limiting the chassis by the sealing ring.

The foregoing embodiments and description have been presented only to illustrate the principles and preferred embodiments of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as hereinafter claimed.
