To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in fig. 1 to 6, an embodiment of the present invention discloses a lamp panel 10 clamping mechanism, which includes: main part 20, lamp plate 10, card protruding 42, draw-in groove 41 and elastic plate 30.

The main body portion 20 has an annular outer edge, an annular stepped surface 21 is formed at the outer edge, a plurality of engaging grooves 41 are formed on the stepped surface 21, and the plurality of engaging grooves 41 are circumferentially arranged. Each of the engaging grooves 41 is defined by two opposite enclosing plates, the two enclosing plates enclose an oval groove cavity, and the opening of the engaging groove 41 faces downward.

The inboard position that is close to the edge of lamp plate 10 is provided with a plurality of blocks of protruding 42 with draw-in groove 41 one-to-one, and every blocks of protruding 42 all borrows the inboard of fixing at lamp plate 10 by basic seat 43, and the cross-section of every blocks of protruding 42 also is oval-shaped, and this makes, blocks of protruding 42 and can force two bounding walls to warp and stretch into draw-in groove 41 through the notch to, need certain pulling force just can extract the protruding 42 of card from draw-in groove 41.

The elastic plate 30 has a plurality of elastic plates 30, and the plurality of elastic plates 30 are circumferentially arranged at the edge of the inner side of the lamp panel 10, as shown in fig. 6, each elastic plate 30 may have one bending, as shown in fig. 2, or two bending, and each elastic plate 30 is located at the outer side of the snap protrusion 42 in the radial direction.

When the locking protrusion 42 extends into the locking groove 41, the elastic plate 30 abuts against the stepped surface 21 with a certain elastic force, and the elastic force of the elastic plate 30 against the stepped surface 21 is smaller than the force required to pull out the locking protrusion 42.

So, lamp plate 10 keeps with the help of the protruding 42 of card and draw-in groove 41's cooperation and with main part 20's lock state, simultaneously, makes lamp plate 10 and buckle form certain tension through the elasticity of elastic plate 30 to step face 21, and then can effectively avoid the relative main part 20 drunkenness of lamp plate 10 on the thickness direction, has improved the stability of lamp plate 10 installation.

In some preferred embodiments, as shown in fig. 3 and 4, a through hole 421 is formed in the middle of the snap-fit projection 42, the through hole 421 is formed by two oval holes intersecting with each other, and the major axes of the two oval holes are perpendicular (or, the minor axes of the two oval holes are perpendicular). Moreover, the long axis of one elliptical hole is coaxial with the long axis of the clamping protrusion 42, and the long axis of the other elliptical hole is always perpendicular to the long axis of the clamping protrusion 42; the through hole 421 is penetrated by the adjusting shaft 50, the cross section of the adjusting shaft 50 is also elliptical, and: the long axis of the cross section of the adjusting shaft 50 is larger than the long axis of the elliptical hole perpendicular to the long axis of the snap projection 42 and is approximately equal to the long axis of the other elliptical hole; in addition, the locking projection 42 is provided with a notch 422, and the notch 422 penetrates through the front end of the locking projection 42 and an elliptical hole in the through hole 421, which is consistent with the long axis of the locking projection 42.

When factory installation is performed, the through hole 421 is bored in the adjustment shaft 50 in the following posture: as shown in fig. 4, the major axis of the adjustment shaft coincides with the major axis of the elliptical hole through which the slit 422 passes.

And lead to the card protruding 42 and draw-in groove 41 to produce permanent deformation or wearing and tearing back through lamp plate 10 dismouting many times, before card protruding 42 inserts draw-in groove 41 again, pivot adjusting shaft 50, as shown in fig. 5, the major axis that makes adjusting shaft 50 is unanimous with the major axis of the elliptical aperture that is not link up by opening 422, this can make the card protruding 42 produce the inflation in order to compensate the increase of the notch of draw-in groove 41 that permanent deformation or wearing and tearing caused, and then make and need great power just to make card protruding 42 extract from draw-in groove 41 all the time.

In some preferred schemes, the region of the elastic plate 30 abutting against the stepped surface 21 is processed into a contact plane 31, an embedding groove 211 is opened at the position of the stepped surface 21 opposite to the contact plane 31, an elastic pad 212 is installed in the embedding groove 211, and the elastic strip can be a rubber pad or a silicon rubber pad. Thus, the elastic force of the elastic plate 30 against the step face 21 is applied to the elastic pad 212. In this way, not only can the wear of the elastic plate 30 be reduced, but also the frictional force in the radial direction between the elastic plate 30 and the stepped surface 21 can be improved, and further, the stability of the lamp panel 10 and the main body portion 20 in the radial direction can be improved.

In some preferred embodiments, the extension plate 32 is formed at the tail of the elastic plate 30, the extension plate 32 is integrally formed with the elastic plate 30, the extension plate 32 has a curvature identical to that of the lamp panel 10, the extension plate 32 is adhered to the inner side of the lamp panel 10 by glue, so that the extension plate 32 can be better adhered to the inner side of the lamp panel 10, and the base seat 43 is adhered to the inner side of the extension plate 32.

In some preferred embodiments, the elastic plate 30 slightly protrudes from the edge of the lamp panel 10, and the protective plate 22 is formed at the edge of the main body 20, and when the lamp panel 10 is fastened to the main body, the portion of the elastic plate 30 protruding from the outer side of the lamp panel 10 is shielded by the protective plate 22, so that after the lamp panel 10 is installed, the whole lamp body has better appearance quality.

The elastic plate 30 may be formed by bending a metal plate or integrally injection-molded and thermoplastic-molded from a plastic material.

The above-described notch 41 may be integrally formed with the main body 20, or may be separately formed and fixed to the stepped surface 21 of the main body 20.

The cover plate 22 is integrally formed with the main body 20 to obtain a better appearance of the entire lamp body.

The lamp panel 10 clamping mechanism provided by the invention has the advantages that:

1. utilize the elasticity of elastic part to the ladder face 21 of main part 20 and make lamp plate 10 still form tension between by draw-in groove 41 joint while with main part 20, this tension can effectively avoid lamp plate 10 to produce the drunkenness, and then can improve the stability of lamp plate 10 installation.

2. Through set up opening 422 and through-hole 421 on calorie protruding 42 to wear to establish the cross-section on through-hole 421 and be oval adjustment shaft 50, and then can change the cross sectional dimension of calorie protruding 42, and then can avoid wearing and tearing or the joint effect that permanent deformation influences through adjusting cross sectional dimension.
