In the figure: the cap shell 1, the sliding cover 2, the lens 3, the mounting hole 4, the clamping ring 5, the key groove 6, the sliding rail 7, the connecting key 8, the top cover 9 and the pressing groove 10.
Detailed Description
The technical solutions in the embodiments of the present invention will be clarified with reference to the drawings in the embodiments of the present invention
Clearly, fully described:
as shown in fig. 1 and 2, the present invention includes a cap housing 1, a sliding cover 2, a lens 3, and a snap ring 5. The front side of the cap shell 1 is symmetrically provided with clamping rings 5. The snap ring 5 is connected with the cap shell 1. The lens 3 is provided with mounting holes 4 in bilateral symmetry. The sliding cover 2 passes through the mounting hole 4 on the lens 3 and is connected with the snap ring 5. The lens 3 is fixed on the cap shell 1 through the connection of the sliding cover 2 and the snap ring 5.
As shown in fig. 3 and 4, the slide cover 2 includes a connection key 8 and a top cover 9. The top cover 9 is provided with two pressing grooves 10. Two pressing grooves 10 are respectively located at both sides of the top cover 9. The snap ring 5 is provided with a key slot 6 and a slide rail 7. The connecting key 8 on the sliding cover 2 penetrates through the mounting hole 4 on the lens 3 to be connected with the key groove 6 on the snap ring 5, the connecting key 8 on the sliding cover 2 moves on the sliding rail 7 by shifting the sliding cover 2, and the lens 3 is fastened on the cap shell 1 by utilizing the pretightening force of the sliding rail 7 to the connecting key 8. The slide rail 7 of the snap ring 5 is horizontally disposed so that the slide cover 2 can slide in a horizontal direction.
As shown in FIG. 4, in use, the slide cover 2 is slid to mount and dismount the lens 3 by pressing the pressing groove 10 on the top cover 9 of the slide cover 2.
As shown in fig. 3, the axial cross-sectional shape of the connection key 8 on the sliding cover 2 is t-shaped, when the lens 3 is installed, the pressing groove 10 on the sliding cover 2 is pressed, the sliding cover 2 is pushed, so that the connection key 8 on the sliding cover 2 passes through the installation hole 4 on the lens 3, then the connection key 8 on the sliding cover 2 is connected with the key groove 6 on the snap ring 5, and after connection, the connection key 8 is moved to the slide rail 7 on the snap ring 5, because the connection key 8 on the sliding cover 2 is designed to be t-shaped, the connection key 8 is tightly connected with the snap ring 5. At this time, the top cover 9 on the slide cover 2 fastens the lens 3 to the cap housing 1 by engaging with the mounting hole 4 on the lens 3.
As shown in fig. 4, when the lens 3 is removed, the pressing groove 10 on the sliding cover 2 is pressed to move the connecting key 8 on the sliding cover 2 from the sliding track 7 on the snap ring 5 to the key slot 6 on the snap ring 5. The connecting key 8 is then removed from the snap ring 5 through the mounting hole 4 in the lens 3, thereby removing the lens 3 from the cap housing 1.
The snap ring 5 is integrally provided with the cap case 1 or the snap ring 5 is independently provided.
The snap ring 5 is a straight sliding type snap ring and is made of plastic.
The sliding cover 2 is made of plastic.
The above description of the present invention is intended only to illustrate the structure of the present invention. The utility model
Various modifications or additions may be made to the described embodiments or similar ones may be adopted by those skilled in the art
Instead, the present invention shall fall within the scope of the claims without departing from the structure thereof or exceeding the scope of the claims
