Description

Waterproof sealing protective cover structure for double-shot molding

Technical Field

The utility model relates to a waterproof equipment technical field, concretely relates to waterproof sealing visor structure of double-shot moulding plastics.

Background

On professional communication equipment and terminals, for example, in order to realize functions such as data interaction with a cloud and remote control, some of the professional communication equipment and terminals need to load a mobile network card (SIM/Micro SIM/Nano SIM and the like) on the equipment or a memory card (SD/Micro SD and the like) for increasing a storage function, and the position of the card is required to have a certain waterproof capability. However, the existing waterproof structure on the equipment has low air tightness or high air tightness, which is inconvenient for users to disassemble and assemble. Generally comprises the following structures:

(1) structure A, front side waterproof, referring to FIG. 4, a protective cover a1 is locked on a housing a4 through a screw a2, and a sealing ring a3 is compressed to seal and prevent water;

when the structure scheme A is produced and assembled, the sealing ring is firstly arranged in the waterproof groove of the shell, then the protective cover is assembled and locked by the screw, the scheme is waterproof and reliable, and can reach IPX7 or higher, but the production and the operation are inconvenient, the number of assembly parts is large, and the assembly operation can be carried out only by tools such as a screwdriver and the like when the user is on hand;

(2) and structure B: the side is waterproof, referring to fig. 5, the protective cover b1 is fastened by a back-off b2, and a circle of protrusions b3 are arranged on the protective cover b1, and after assembly, a sealing ring is in interference fit with the shell b4 to be waterproof;

the structure scheme B has relatively simple structure and few parts, can realize basic sealing, but because the soft rubber is directly in interference fit with the shell, the soft rubber is easy to plastically deform under stress for a long time, so that the long-time sealing reliability is reduced, and the soft rubber is not suitable for products with higher waterproof requirements;

(3) and structure C: the side edge is waterproof, referring to fig. 6, the protective cover c1 is fastened through an inverted buckle c2, a sealing ring c3 is sleeved on the protective cover c1, the sealing ring c3 and the shell c4 are in interference fit for sealing and waterproofing, and meanwhile, a metal sheet c5 is embedded into the soft rubber protective cover c1 for supporting, so that plastic deformation caused by long-time compression of soft rubber is prevented;

the structure scheme C is that on the basis of the structure scheme B, a waterproof ring is used for replacing a convex hull on a soft rubber, and a metal sheet is used for supporting a soft rubber protective cover, so that the strength is increased, the deformation is prevented, the scheme is waterproof and reliable, the IPX7 level can be achieved, the cost of an additional metal sheet is required, and the additional requirements of a mold, processing and metal corrosion prevention are met.

Therefore, further improvements are needed in the art.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a waterproof sealing visor structure of double-shot moulding plastics.

The technical scheme of the utility model is that:

the utility model provides a waterproof sealing visor structure of double-colored injection molding, includes visor, fixed block, sealing washer and buckle, the fixed block is fixed in on the protective cover, the sealing washer is installed on the fixed block, the buckle is installed in visor one end, and the other end of this visor is fixed in on the equipment shell, and the visor is opened and closed at any time to the accessible buckle.

Preferably, the protective cover and the fixed block are manufactured by double-shot injection molding.

Preferably, the lateral wall of fixed block is equipped with the recess for place the sealing washer.

Preferably, the middle part of the fixed block is also provided with a plurality of openings, so that the injection molding is convenient.

Preferably, the protection cover and the fixed block are formed with a boss reverse buckle on the side wall of the fixed block after injection molding, so as to prevent the protection cover from falling off after assembly.

Adopt the technical scheme of the utility model, following beneficial effect has:

1. the sealing ring is not in direct contact with the soft rubber, and does not apply pressure stress of interference fit to the soft rubber, so that the waterproof reliability is high, and the sealing ring can be suitable for products with IP67 or higher sealing requirements;

2. the protective cover is formed in one step through double-color injection molding, other parts do not need to be manufactured additionally, and the material cost, the transportation cost and the like of the parts are reduced;

3. the visor passes through the buckle to be fixed at the shell, can open at any time and close, and bare-handed operation can be accomplished, and is very convenient.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, the utility model provides a waterproof sealing visor structure of double-shot moulding, including visor 1, fixed block 2, sealing washer 3 and buckle 4, fixed block 2 is fixed in on visor 1, sealing washer 3 is installed on fixed block 2, buckle 4 is installed in 1 one end of visor, and on this visor 1's the other end was fixed in equipment shell 6, visor 1 was opened and closed at any time to accessible buckle 4.

The protective cover 1 and the fixed block 2 are manufactured by double-shot injection molding; the side wall of the fixed block 2 is provided with a groove 201 for placing the sealing ring 3; the middle part of the fixed block 2 is also provided with a plurality of openings 202, which is convenient for injection molding.
