Detailed Description

For better understanding of the objects, structures, features, and functions of the present application, reference is now made to the following detailed description taken in conjunction with the accompanying drawings.

In the embodiment shown in fig. 1, a waterproof scanning gun 100 is disclosed.

Referring to fig. 2, the scan gun 100 mainly includes an upper case 1 and a handle 2 assembled up and down, and the upper case 1 and the handle 2 together enclose a cavity 3 for accommodating internal components.

As shown in fig. 3, an accommodating groove 4 is formed in the handle 2, the accommodating groove 4 opens upwards into the cavity 3, and a through hole 5 communicating with the cavity 3 is formed in an inner wall of the accommodating groove 4. A fence 6 is arranged on the periphery of the opening at the upper end of the containing groove 4. A trigger button 7 is installed in the receiving groove 4 from the upper end opening of the receiving groove 4, and the trigger button 7 is provided with a convex column 8 corresponding to the through hole 5.

A first sealing ring 9, the lower surface of which is provided with a ring of clamping grooves 10, so that the first sealing ring 9 is clamped at the upper end of the fence 6 through the clamping grooves 10, and a cover plate 11 is abutted against the first sealing ring 9 to seal the upper end opening of the containing groove 4. The cover plate 11 is provided with a screw hole 12, and the cover plate 11 is fixed on the handle 2 through a bolt 13. A second sealing ring 14 is disposed between the upper casing 1 and the handle 2 for sealing a gap between the upper casing 1 and the handle 2, the second sealing ring 14 is preferably injection-molded on the handle 2, and when the upper casing 1 is assembled to the handle 2, the second sealing ring 14 is squeezed to form a seal. A sealing element 15 seals the through hole 5, the convex column 8 of the trigger button 7 is used for pushing the sealing element 15 so as to trigger a switch 16 in the cavity 3, and the sealing element 15 is preferably formed by elastic silica gel so as to provide a certain elastic force. The first sealing ring 9 and the sealing member 15 separate the receiving groove 4 from the cavity 3, so that liquid does not enter the cavity 3 from the receiving groove 4, thereby achieving excellent waterproof performance.

A circuit board 17 is installed in the cavity 3, and the switch 16 is installed on the circuit board 17.

The cover plate 11 is preferably formed by integral injection molding with the trigger button 7, and as shown in fig. 4, the cover plate and the trigger button are connected by an elastic arm 18, so that the mold is saved, and the assembly is convenient; after the cover plate 11 is installed and fixed, the trigger button 7 is limited, and when the trigger button 7 is pressed, the elastic arm 18 provides a certain elastic force to be matched with the sealing element 15, so that the trigger button 7 is forced to rebound.

In other embodiments (not shown, the same applies below), the cover plate 11 may be provided separately from the trigger button 7.

The scanning gun of the application has the following beneficial effects:

according to the scanning gun 100, the containing groove 4 for containing the trigger button 7 is provided with the cover plate 11 for sealing at the upper end opening, and the through hole 5 communicated with the cavity 3 in the scanning gun 100 is sealed by the sealing element 15, so that liquid cannot enter the cavity 3 from the containing groove 4, and the waterproof performance of the scanning gun 100 is provided.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present application, and not for the purpose of limiting the scope of the present application, therefore, all technical changes that can be made by applying the present specification and the drawings are included in the scope of the present application.
