The present invention relates to a lamp cover, and more particularly, to a lamp cover that is easy to combine and detach.

Lamps are generally installed in ceilings for lighting and interior lighting, such as an office. Specifically, a ceiling lamp is fixed to the ceiling, and a predetermined number of lamps are mounted to the ceiling lamp. However, such a purchase lamp is not only aesthetically neat because the lights are exposed, but also has a disadvantage of being unsuitable for use in a place to produce a clean and luxurious atmosphere, such as a general house. Therefore, in recent years, it is common that the lamp cover is detachably fixed to the lamp mounting part so as not to expose the lamp to the outside and to impart a decorative effect.

However, in the related art, since the cover is detachably fixed to the lamp mounting part using a plurality of fasteners such as bolts and nuts, fixing and removing the lamp cover have been very cumbersome and difficult. In particular, when replacing a lamp or There has been a problem in that the cover cannot be quickly and easily assembled and detached structurally during cleaning.

Accordingly, the present invention has been made to solve the problems of the lamp cover according to the prior art as described above, and an object thereof is to provide a lamp cover that can be easily coupled and separated in a one-touch manner.

The objects and advantages of the present invention will be described in more detail below, and will be further embodied by the examples. Furthermore, the objects and advantages of the present invention can be realized by the means indicated in the claims and combinations thereof.

The lamp cover according to the present invention for achieving the object as described above, in the lamp cover including a rectangular frame 10 is connected to a plurality of extrusion bar, and a floodlight plate 100 coupled to the lower frame 10 In addition, the upper surface outer end of the frame 10 is coupled to the pivoting rotatable operation piece 20 along the longitudinal direction so that the lamp cover is coupled to and separated from the end of the lamp mounting portion 200, the pivoting operation piece ( One side of 20 has a shaft groove 22 which is bent vertically and opened inward at its distal end, and the shaft groove 22 of the pivoting operation piece 20 along the longitudinal direction at an upper end portion of the upper surface of the frame 10. And a shaft pin 12 inserted / connected thereto, and a rear surface of the shaft pin 12 is provided with a first receiving groove 13 open inwardly, and the other side of the pivoting operation piece 20 has the first accommodation portion. It is bent to face the groove 13 and at its end It is provided with a second receiving groove 15, characterized in that the plate-like member 30 is inserted between the first receiving groove 13 and the second receiving groove (15).

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration and operation of the lamp cover according to the present invention.

1 is a perspective view of a lamp cover according to the present invention, Figure 2 is an exploded view of the lamp cover according to the present invention, Figure 3 and Figure 4 is a cross-sectional view of the lamp cover according to the present invention, respectively. As shown, the lamp cover according to the present invention is composed of a frame 10, a floodlight plate 100, the turning operation piece (20).

The frame 10 is formed by cutting a plurality of extruded bars having a '-' shape having a predetermined length in a predetermined length, and the light transmitting plate 100 may be inserted / supported under the frame 10. The light-transmitting plate inserting groove 14 opened inward is provided. The floodlight plate 100 to be inserted into the insertion groove 14 is preferably made of synthetic resin such as acrylic or glass material. Although there is no limitation in the method of connecting the plurality of extruded bars, as shown in the drawing, an opening is formed on the inner side of the upper surface of the frame 10 upwardly in the longitudinal direction, and the hook is formed to protrude in a direction facing each other. A jaw-shaped T-shaped fitting groove is formed, and the 'A'-shaped connecting piece 16 is inserted into the fitting groove in the corner portion, which is a connection part of each extrusion bar, by sliding the screw fastened to the connecting piece 16 ( 18) is preferably configured to interconnect each extruded bar by tightening.

According to the present invention, the upper surface outer end of the frame 10 is provided with a shaft pin 12 having a generally circular cross section along the longitudinal direction. The shaft pin 12 is coupled to the shaft groove 22 of the swing operation piece 20 to be described later to enable the swing operation of the swing operation piece 20. The first receiving groove 13 which is opened inward is formed on the rear surface of the shaft groove.

Swivel operation piece 20 is coupled to the upper surface outer end of the frame 10. The pivoting operation piece 20 should be pivotally coupled so that the lamp cover can be coupled and separated by the clamping operation with the end of the lamp mounting portion 200 installed on the ceiling. To this end, the pivoting operation piece 20 is formed in a flat plate shape extending in the longitudinal direction of the outer end of the frame 10, one side of which is bent vertically and the end inward in the longitudinal direction An open shaft groove 22 is provided. A shaft pin 12 of the outer end of the frame 10 is inserted into the shaft groove 22 to enable the swinging operation of the swinging operation piece 20. The other side of the turning operation piece 20 is bent again in the direction toward the first receiving groove 13. As shown, the other side of the swinging operation piece 20 is preferably bent in a 'c' shape. The second receiving groove 15 is formed at the distal end of the turning operation piece 20 bent in this way.

The plate member 30 is firmly inserted between the first receiving groove 13 and the second receiving groove 15. The plate member 30 is preferably composed of a metal plate, it is inserted so as to cross a straight line between the first receiving groove 13 and the second receiving groove (15). The bottom surface of the first accommodating groove 13 is generally arcuate in shape so that one end of the plate member 30 may be moved while being rubbed with the inside of the first accommodating groove 13 during the swinging operation of the swinging operation piece 20. It is preferable to be curved concave inwardly, the second receiving groove 15 is concave inwardly corresponding to the thickness of the plate member 30 so as to firmly grip the other end of the plate member 30. It is preferable to bend. The plate member 30 is a component for preventing the separation / separation of the coupling when the lamp cover is coupled to the lamp mounting portion 200. As described above, since the plate member 30 is firmly inserted between the first receiving groove 13 and the second receiving groove 15, when the pivoting operation piece 20 is tilted, the first Since the inside of the receiving groove 13 and one end of the plate-like member 30 are so firmly contacted that a relatively large frictional force is applied, the turning operation piece 20 will not be tilted unless a greater force than this frictional force is applied from the outside. . If the external force is greater than the friction force, one end of the elastic member 30 is moved along the concave curved arcuate surface of the first receiving groove 13 so that the pivoting operation piece 20 is pivoted, again. Because of the frictional force, the turning operation piece 20 is prevented from turning in the reverse direction. The turning angle of the turning operation piece 20 is limited by the locking step formed on the upper and lower portions of the first receiving groove 13.

Therefore, when the lamp cover according to the present invention is coupled to the lamp mounting portion 200, the pivoting operation piece 20 is pivoted by the load of the cover unless the lamp cover is artificially pulled downward so that the cover is separated / detached. You can prevent that.

Hereinafter, the operation principle of the coupling and separation of the lamp cover according to the present invention with reference to FIGS. 3 is a cross-sectional view showing a state before the lamp cover according to the present invention is coupled, and FIG. 4 is a cross-sectional view showing a state after the lamp cover according to the present invention is coupled.

As shown in FIG. 3, before the coupling of the lamp cover according to the present invention, the pivoting operation piece 20 is pivoted upward to be in a lifted state. The lamp 300 is installed in the lamp mounting portion 200 fixed to the ceiling by a predetermined fastening means. At this time, when the operator pushes the lamp cover upwards, the upper portion of the turning operation piece 20 against the ceiling is pressed downwards so that the turning operation piece 20 pivots about the shaft pin 12. When the pressing force is less than the frictional force between the one end of the plate member 30 and the inner surface of the first receiving groove 13, the turning operation of the swinging operation piece 20 is not made, and if it is higher than the plate member 30 The one end portion of the pivot is moved upwardly along the circular arc of the first accommodating groove 13 until the pivoting operation piece 20 is pivoted.

When the pivoting operation piece 20 is fully pivoted, as shown in FIG. 4, the lower end of the pivoting operation piece 20 is supported by an end of the lamp mounting portion 200 installed on the ceiling. In this case, the friction force is applied again between the plate member 30 and the first receiving groove 13 to prevent turning in the reverse direction, and the turning operation piece 20 is kept in a closed state.

When the user wants to remove the lamp cover for the replacement of the lamp 300, the cover is pulled downward as opposed to the case of the coupling. When the cover is pulled downward, a force is applied to the end of the swinging operation piece 20 held by the end of the lamp mounting portion 200, and when this force is equal to or greater than the frictional force, the swinging operation piece 20 is pivoted. Again, as shown in FIG. 3, the turning operation piece 20 is opened.
