Detailed description of the invention

In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing explanation Detailed description of the invention of the present utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, this utility model provides a kind of silica gel sheath 1, is used for being sleeved on a product 2 to be protected Outward, the electronic product such as product 2 to be protected for example, walkman audio amplifier, portable power source, camera or mobile phone；

Shown in Fig. 4, Fig. 5, wherein, silica gel sheath 1 has at least one opening 11, waits to protect for being loaded by opening 11 Protecting product 2, when silica gel sheath 1 is not set with product 2 to be protected, silica gel sheath 1 has molding length L1, and opening 11 has Molding length L2, when silica gel sheath 1 is set with product 2 to be protected, silica gel sheath 1 has installation length L3, and opening 11 has Having installation length L4, molding length L1 is less than installation length L3, and molding length L2 is less than installation length L4, molding length L1 and peace The difference of dress length L3 is the first predeformation amount, and molding length L2 is the second predeformation amount with the difference of installation length L4, passes through Silica gel sheath 1 is done predeformation design (owing to deformation direction during direction and the silica gel sheath suit product to be protected of predeformation is contrary, Alternatively referred to as reverse predeformation), compensate the deflection after silica gel sheath 1 is set with product 2 to be protected, prevent the lax change of silica gel sheath 1 Shape, improves protection effect.

Specifically, the occurrence of the first predeformation amount and the second predeformation amount be required to according to silica gel sheath in reality 1 with treat The matching degree of protection product 2 is determined, and needs silica gel sheath 1 and the attaching degree of product 2 to be protected, installs complexity Consider etc. factor.

Wherein, in embodiment described in Fig. 1, the first predeformation amount for example, 4mm, the second predeformation amount for example, 4mm, both The deflection after silica gel sheath 1 is set with product 2 to be protected can be compensated, the most do not affect product 2 to be protected and load silica gel sheath 1 smoothly.

It addition, molding length L2 is less than molding length L1, to prevent product 2 to be protected from deviating from from opening 11.

Additionally, the shape of silica gel sheath 1 and the mating shapes of product 2 to be protected, in order to product 2 to be protected can be attached to Outward, good protection effect is played；The shape of silica gel sheath 1 can be capsule shape, the shape of silica gel sheath 1 can also be cylindric or Other shapes, specifically can be determined according to the shape of product 2 to be protected.

As shown in Figure 4, Figure 5, in a preferred embodiment, opening 11 has shaping area S1, is set with at silica gel sheath 1 Under the state of product 2 to be protected, opening 11 has erection space S2, and shaping area S1 is less than erection space S2, in other words opening The molding girth at edge less than the installation girth of edge of opening, i.e. relative to being set with product 2 to be protected after, silica gel sheath 1 is not set with Opening 11 during product 2 to be protected inside contracts (for reducing), to be further compensate for the deformation after silica gel sheath 1 is set with product 2 to be protected Amount, effectively prevents the lax deformation in long limit at the edge of opening 11, especially opening 11, it is to avoid the edge of opening 11 is the most straight, carries High protection effect.

Further, the global formation of silica gel sheath 1 is smaller in size than the integral installation size of silica gel sheath 1.

Further, opening 11 be shaped as elongated hole, it is simple to product 2 to be protected is loaded silica gel sheath 1.

Wherein, for example, two, the edge of opening 11 the is parallel long limit being oppositely arranged and two circular arcs relative The minor face arranged, is designed by the L2 structure less than L4, can effectively prevent long limit from relaxing.

Further, opening 11 is two, and is symmetricly set on top and the bottom of silica gel sheath 1, i.e. silica gel sheath 1 ringwise, Silica gel sheath 1 energy semi-surrounding is outside product 2 to be protected.

Further, silica gel sheath 1 offering spaced multiple perforate 12, perforate 12 can be uniformly or non-uniformly to divide Cloth, by arranging perforate 12, it is simple to the elasticity of increase silica gel sheath, the heat radiation of product 2 the most to be protected, for walkman audio amplifier, It is also convenient for entrant sound.

Further, the end of silica gel sheath 1 offers dodges hole 13, for dodging the handle of product 2 to be protected.

The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to model of the present utility model Enclose.Any those skilled in the art, the equivalent variations made on the premise of without departing from design of the present utility model and principle With amendment, the scope of this utility model protection all should be belonged to.And it should be noted that each ingredient of the present utility model also Being not limited only to above-mentioned overall applicability, each technical characteristic described in description of the present utility model can select according to actual needs One independent employing or select the multinomial use that combines, therefore, this utility model covers and this case invention in the nature of things Put other relevant combination and specifically apply.
