[0007] Further, the four corners of the frame are round corners, and correspondingly, the four corners of the front cover and the rear cover are also round corners, which improves the overall strength and firmness.

[0008] Further, the front cover, the rear cover and the frame are made of explosion-proof and impact-resistant materials.

[0009] Further, the width of the four edges of the frame is 0.8-2.0 cm.

[0010] Further, a pair of hangers is arranged on the upper side of the back of the rear cover, which facilitates wall hanging.

[0011] Further, the back cover rear bottom is provided with a wire hole, and the circuit board light source is connected with an external power supply through a connecting wire passing through the wire hole.

[0012] Further, the back cover middle front is convex, forming a plane with a shape consistent with the back cover and a size smaller than the back cover, and the impact force on the front cover is dispersed by the convex front of the back cover.

[0013] Compared with the prior art, the four-side equal-width sign lamp has the following advantages:

[0014] Through the four-side equal-width frame and the convex front of the back cover, the stability, force balance, impact resistance and explosion resistance of the overall structure are improved, the wire hole connected with the power supply is arranged on the back cover, the overall integrity and firmness are further improved, and the impact resistance is further improved.
