A specific implementation of the present embodiment is described below with reference to fig. 1 to 6.

As shown in fig. 1, the present embodiment provides a mask assembly, which includes a frame 10 of a lamp and a mask 20, wherein the frame 10 is a circular frame, the frame 10 has a circular inner surface, the mask 20 is a circular disc, and the diameter of the mask 20 is slightly smaller than the inner diameter of the frame 10, so that the mask 20 can be assembled inside the frame 10.

In this embodiment, the inner surface of the frame 10 is provided with a buckle 110 and an elastic rib 130; the edge of the face guard 20 is provided with a buckling groove 210, a guide groove 220 and a positioning groove 230, a blocking structure is arranged between the guide groove 220 and the positioning groove 230, a gap is formed between the blocking structure and the frame 10, the face guard 20 can rotate along the inner surface of the frame 10, and the elastic convex rib 130 can deform in the rotating process to bypass the gap, so that the face guard 20 is switched between the first position and the second position.

In the first position, the elastic rib 130 is located in the guide groove 220, and the buckle 110 corresponds to the buckle groove 210; the mask 20 is rotated to the second position, the elastic rib 130 is located in the positioning groove 230, and the buckle 110 is dislocated from the buckle groove 210. At this time, the elastic ribs 130 are clamped in the positioning grooves 230, so as to prevent the mask 20 from rotating to the first position, thereby ensuring the stability of the installation of the mask 20 and ensuring that the mask 20 cannot fall off.

As shown in fig. 1 and 2, in this embodiment, the annular inner surface of the frame 10 is provided with the clip 110 and the baffle 120, and the clip 110 and the baffle 120 are disposed at intervals along the height direction of the frame 10, so that a gap is formed between the clip 110 and the baffle 120, and the gap serves as a mounting groove in which the mask 20 can be mounted.

Preferably, the baffle 120 is disposed at the edge of the frame 10, and the width of the gap between the buckle 110 and the baffle 120 is slightly larger than the thickness of the mask 20, so that when the mask 20 is located in the installation groove, the two ends of the mask 20 are respectively supported by the buckle 110 and the baffle 120, and the mask 20 is ensured to be stably installed.

In this embodiment, the elastic ribs 130 are pressed to contract toward the surface of the frame 10.

It should be noted that, the elastic rib 130 is to be disposed inside the mounting groove, or at least a portion of the elastic rib 130 is to extend into the mounting groove, so that after the mask 20 is mounted, the elastic rib 130 is located in the plane of the mask 20, so that the elastic rib 130 can contact with the mask 20.

As shown in fig. 1, the mask 20 has a circular profile with edges provided with a snap groove 210, a guide groove 220, and a positioning groove 230. A blocking structure is provided between the guide groove 220 and the positioning groove 230. It should be noted that the outermost end of the blocking structure does not exceed the circular contour of the mask 20, so that when the mask 20 is placed in the mounting groove, the blocking structure does not contact the inner wall of the rim 10, so that a gap is formed between the blocking structure and the inner wall of the rim 10.

In this embodiment, the size of the snap groove 210 is larger than the snap 110 so that the mask 20 can be placed into the mounting groove through the snap 110. And the elastic bead 130 is just inside the guide groove 220 when the face mask 20 is just put into the installation groove.

In the embodiment of the utility model, the mask 20 is connected with the frame 10 in a rotating manner, the mask 20 is assembled in the mounting groove and can rotate along the mounting groove, and the mask 20 has a first position and a second position after rotating.

As shown in fig. 3, the face mask 20 is in a first position, which is a state in which the face mask 20 is initially placed in the mounting groove. In the first position, the elastic rib 130 is located in the guide groove 220, and the buckle 110 is located in the buckle groove 210.

In this embodiment, the guide slot 220 has a length such that the elastic rib 130 moves in the guide slot 220 during rotation of the mask 20.

During installation, the elastic rib 130 is not rotationally moved, and as the mask 20 rotates, the blocking structure approaches the elastic rib 130, and the rotation of the mask 20 causes the blocking structure to press the elastic rib 130, and the elastic rib 130 contracts and squeezes into the gap between the blocking structure and the inner wall of the frame 10 under the pressing condition, and the elastic rib 130 bypasses the blocking structure by the gap and enters the positioning groove 230, so that the mask 20 rotates to the second position.

As shown in fig. 5, the mask 20 is in a second position, which is a clamped position of the mask 20. In the second position, the elastic rib 130 moves from the guide groove 220 to the positioning groove 230 by bypassing the blocking structure, and the buckle 110 is staggered from the buckle groove 210.

The mask 20 is positioned in the mounting groove, and the buckle 110 is staggered from the buckle groove 210, so that the mask 20 is clamped in the frame 10, and the mask 20 is mounted and fixed. Meanwhile, the positioning groove 230 in this embodiment is smaller in size, the elastic ribs 130 are abutted in the positioning groove 230 to play a limiting role, and the elastic ribs 130 are just clamped in the positioning groove, so that the mask 20 cannot easily rotate after rotating in place, the mask 20 is effectively prevented from rotating, and the mask 20 is prevented from falling off.

The mode of rotatory installation is adopted in this embodiment, and the installation is simple quick, can not block the face guard 20, realizes through the dislocation of buckle 110 and buckle groove 210 that the joint of face guard 20 is fixed, prevents that face guard 20 is rotatory to the spacing of elasticity protruding muscle 130 through constant head tank 230, guarantees the stability of face guard 20 installation, effectively prevents that face guard 20 from droing.

As shown in fig. 4 and 6, in one embodiment, the guide slot 220 is disposed adjacent to the positioning slot 230, and the blocking structure is a stopper 240, and the guide slot 220 is spaced apart from the positioning slot 230 by the stopper 240.

When the mask 20 is switched from the first position to the second position, the stop 240 moves to the elastic rib 130 and presses the elastic rib 130 towards the direction of the frame 10, so that the elastic rib 130 can bypass the stop 240 through the gap, and move from the guide groove 220 to the positioning groove 230, thereby realizing the position switching and positioning of the mask 10 in the first position and the second position.

Specifically, in the first position, as the mask 20 rotates, the elastic rib 130 approaches the stop 240 at one end of the guide slot 220 toward the other end, the stop 240 moves to abut against one side of the elastic rib 130, and as the mask 20 continues to rotate, the stop 240 presses the elastic rib 130 to move in the direction of the other side of the elastic rib 130.

In the second position, the stop block 240 presses the elastic rib 130 to reach the other side of the elastic rib 130, and at this time, the elastic rib 130 is located in the positioning groove 230, and the positioning groove 230 plays a limiting role on the elastic rib 130, so as to prevent the mask 20 from rotating.

As shown in fig. 4, in one embodiment, a guide slope 241 is provided at a side of the stopper 240 adjacent to the guide groove 220, and the guide slope 241 is used to contact the elastic bead 130 and press the elastic bead 130 to move the elastic bead 130 from the guide groove 220 into the positioning groove 230. The arrangement of the guide inclined surface 241 facilitates the movement of the elastic rib 130 into the positioning groove 230, and reduces the difficulty of rotation of the mask 20.

Further, in one embodiment, guide slope 241 is a smooth surface, and smooth guide slope 241 may contact and press elastic bead 130 toward frame 10 when rotated, elastically deforming elastic bead 130. In the process of rotating the mask 20, the elastic ribs 130 are continuously extruded and elastically deformed by the smooth guide inclined surfaces 241, so that the elastic ribs 130 can rotate while bypassing the stop block 240 through the gap between the stop block 240 and the inner surface of the mask 20, and the position switching and positioning of the mask 20 in the first position and the second position are realized.

In this embodiment, the smooth surface reduces the resistance to rotation of the mask 20, and improves the installation efficiency.

Correspondingly, as shown in fig. 4, the elastic rib 130 has a pressing surface 131 at a side close to the guide inclined surface 241, and the pressing surface 131 is an inclined surface for abutting against the guide inclined surface 241. Guide slope 241 contracts resilient bead 130 by pressing against pressing surface 131 to facilitate mask 20 reaching the second position.

In the first position, the pressing surface 131 faces the elastic rib 130 and forms an obtuse angle with the inner surface of the frame 10, so that the pressing surface is pressed towards the frame 10 during rotation.

Preferably, the pressing surface 131 may be a smooth surface, so as to reduce the resistance of the mask 20 to rotation and improve the installation efficiency.

In one embodiment, as shown in fig. 4, the elastic rib 130 is a bending cantilever extending from the inner surface of the frame 10, and in the first position, the bending cantilever is bent at an obtuse angle away from the positioning slot 230, and the pressing surface 131 is located on the surface of the bending cantilever facing the side of the positioning slot 230.

That is, the end of the elastic bead 130 extends toward a side away from the pressing surface 131, and in the first position, the pressing surface 131 presses against the guide inclined surface 241 to retract the elastic bead 130 toward the frame 10, so that the elastic bead 130 bypasses the stopper 240 and enters the positioning groove 230.

As shown in fig. 6, in the second position, the end of the elastic rib 130 abuts against one side of the stopper 240, and the stopper 240 effectively prevents the elastic rib 130 from being removed from the positioning groove 230.

When the mask 20 needs to be disassembled, the elastic ribs 130 can be pressed to contract towards the frame 10, and the mask 20 is rotated in the opposite direction, so that the elastic ribs 130 return to the guide grooves 220 from the positioning grooves 230, and the buckles 110 correspond to the buckle grooves 210, so that the mask 20 can be taken out.

As shown in fig. 4 and 6, in one embodiment, the stopper 240 is a triangular stopper, one side of which forms an inner wall of the guide groove 220, and the other side of which forms an inner wall of the positioning groove 230. It should be noted that the side of the triangular stopper close to the guide groove 220 is a guide slope 241, and the inclination of the side is larger than that of the other side.

Of course, the guiding slot 220 and the positioning slot 230 may be configured as a slot, a triangular stop block is disposed in the slot, the triangular stop block is biased to one side, the slot is divided into the guiding slot 220 and the positioning slot 230, the guiding slot 220 is smaller than the positioning slot 230, the elastic rib 130 is slidable in the guiding slot 220, and the elastic rib 130 is blocked in the positioning slot 230.

As shown in fig. 3 and 5, in one embodiment, the edge of the mask 20 is further provided with a slot 250, and this embodiment is further configured with a rotating rod, where the rotating rod may be inserted into the slot 250, and the mask 20 may be driven to rotate by the rotating rod, so as to implement a rotational installation operation on the mask 20.

Because the face mask 20 is a planar structure, which is inconvenient to operate after being installed into the rim 10, the swivel bars and the slots 250 improve the convenience of assembling the face mask 20.

In one embodiment, the snap groove 210 is a flared groove to facilitate the snap groove 210 interfacing with the snap 110 and to facilitate the placement of the face mask 20 into the mounting groove.
