Description

Technical Field

[0001] The invention relates to a quick buckling device for a lamp holder and a lamp cover. Background Art

[0002] Tri-proof lamps refer to lamps with waterproof, dustproof and anti-corrosion functions. They are widely used in industrial or outdoor lighting places with strong corrosion, high dust and frequent rain. Due to the particularity of the installation environment of tri-proof lamps, the seal between the lampshade and the lamp holder is required to be reliable to ensure that the internal components are not affected by the external environment, so the lampshade and the lamp holder need to be fastened by a lock. In addition, tri-proof lamps are usually installed at a high height, and their installation and disassembly maintenance are relatively inconvenient. Simple and reliable locks will significantly reduce the difficulty of installation or disassembly maintenance, and can also reduce manufacturing and construction costs. Existing locks are generally set at the connection between the outer edge of the lampshade and the lamp holder. There are multiple locks. During the installation and disassembly process, each lock needs to be manually fastened or opened, and sometimes tools are needed to open the lock, which is relatively inconvenient.

[0036] The device is provided with a push-type lock inside the lampshade and the lamp holder. The elasticity of the spring and the guiding effect of the guide rod in the guide groove are utilized inside the lock. The lock can be engaged or opened by simply pressing. The lampshade and the lamp holder can be disassembled and assembled without additional tools. The device has a simple structure and is easy to operate. A convex portion is provided at the bottom of the lampshade flange to ensure the sealing of the lampshade and the lamp holder. At the same time, after engagement, the bottom of the convex portion is still at a certain distance from the groove, so that the lock can be continuously pressed for disassembly.

[0037] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0038] like Figure 1 As shown, the lock connecting the lampshade and the lamp holder is divided into two parts and fixed on the inner sides of the lampshade and the lamp holder respectively. The lock block on the upper part of the lock is fixed on the inner wall of the lampshade. The lock block can also be integrally formed with the inner wall of the lampshade. The lower part of the lock block is substantially parallel to the side wall of the lampshade. The shape of the lock block is roughly an inverted L shape. The lock blocks are symmetrically distributed on the inner wall of the lampshade. The holder with the movable buckle is fixed on the bottom of the inner wall of the lamp holder near the edge, and the position corresponds to the lock block.

[0039] like Figure 3 As shown, when the lampshade and the lamp holder need to be assembled and installed, the locking block on the side wall of the lampshade is pressed against the base at the bottom of the lamp holder, and the bottom of the locking block generates downward pressure on the movable buckle, and the movable buckle moves downward under pressure, and the compression spring in the inner hole of the movable buckle is elastically compressed and deformed accordingly, and the guide head of the guide rod slides in the guide groove. Since the wall thickness of the guide groove is greater than the wall thickness of the rest of the base (see Fig.15 ), when the guide head slides to the positioning part at the corner of the guide groove, the guide head engages with the guide groove at this position (see Fig.16 ), the locking part of the upper part of the movable buckle partially extends into the interior of the card seat, and the two sides of the locking part shrink through their own elastic deformation, buckling and fixing the buckle feet at the lower part of the lock block (see Figure 2 ), the convex part at the bottom of the lampshade and the sealing strip at the top of the lamp holder squeeze each other to form a sealed space inside the lampshade and the lamp holder, a reinforcing rib is arranged on the upper part of the outer side of the convex part to make the structure of the convex part more stable, the outer side of the lampshade flange squeezes each other with the inner side of the first baffle to make the first baffle slightly tilted outward, and at the same time, the flange and the first baffle are kept in a state of close contact, ensuring the stability of the overall structure after the lampshade and the lamp holder are buckled together without shaking;

[0040] When disassembly is required, just press the lampshade again, the flange continues to move downward relative to the sealing strip, and the guide head slides downward along the guide groove. When the guide head moves to the bottom of the guide groove, the center of the guide head shifts to the right side of the guide groove (see Fig.17 ), while the compression spring in the inner hole at the bottom of the movable buckle drives the movable buckle upward through its own elastic restoring force, the guide head slides out along the right side of the guide groove (see Fig.18 ), the limit block I on the upper rear side of the movable buckle limits the guide rod so that the guide rod can rotate within the set range (see Fig.13 ) until the limiting block on the front side of the movable buckle is engaged with the limiting groove on the front wall of the socket, the locking part on the upper part of the movable buckle extends out of the top of the socket, and the two sides of the locking part are reset and opened under the action of their own elasticity, the locking block and the movable buckle are disconnected, and the lampshade and the lamp holder are also disconnected at the same time.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
