Description

A kind of easy-to-dismount bayonet unit

Technical field

The utility model relates to a kind of handheld portable E-consumer kind equipment, relates in particular to a kind of easy-to-dismount bayonet unit.

Background technique

In the prior art, be threaded that to be connected with buckle be two kinds of common Placements in the handheld portable E-consumer kind equipment.If appearance component and internal component adopt thread connecting mode, screw head will directly expose outside, directly have influence on attractive in appearance; Even adopt foot pad to cover screw, also can obviously see the difference between foot pad and appearance component.

For realizing the overall appearance effect of each face of product, buckle is connected to become the main trend in the product specifications such as mobile phone, panel computer.Yet if the buckle design is improper, complete machine will be difficult to dismounting.

Existing bayonet unit adopts the form of right-angle type buckle 20a usually, and shown in Fig. 1 a, this bayonet unit is difficult to dismounting (referring to Fig. 2).Further; Like Fig. 1 b, it shows the right-angle type buckle 20b of another kind of form: the face that is clasped adopts corners away from an end of buckle matrix, though improved dismantling property to a certain extent; But because it still belongs to right-angle type buckle series, improved degree is limited.And,, also increased the difficulty of the demoulding owing to adopt the form of fillet here.

Therefore, what how to overcome bayonet unit above-mentionedly is difficult to dismantle and the defective of demoulding difficulty, study a kind of bayonet unit that can be convenient to dismantle, also can realize good assembly relation, is the problem that those skilled in the art need solution badly.

The model utility content

The technical problem that the utility model will solve is to provide a kind of easy-to-dismount bayonet unit, and it can guarantee assembly relation good between the surface structure spare.

For realizing above-mentioned purpose, the utility model provides a kind of easy-to-dismount bayonet unit, is used for fixing and cooperates first structural member and second structural member with snap-fitted relation, and said bayonet unit comprises: the buckle matrix is fixedly connected on first structural member; And the buckle head that is used to cooperate buckle, being arranged on a side of buckle matrix, wherein said buckle head also has: the first buckle face is arranged on the buckle head farthest from a side of buckle matrix; The second buckle face and the 3rd buckle face; Two ends from the said first buckle face extend out respectively; A side that is enclosed in the buckle matrix with the said first buckle face forms the buckle head, and wherein said the 3rd buckle face is provided with respect to the longitudinal axis of said buckle matrix obliquely.

Further, said the 3rd buckle is facing away from the direction of the second buckle face and is extending, and the longitudinal axis of the 3rd buckle face and buckle matrix in obtuse angle.

Further, the longitudinal axis of said second buckle face and said buckle matrix is provided with tilting.

Further, said bayonet unit is equipped with on the casing of handheld portable electronic product.

According to the utility model, through adopting the bayonet unit of tilting, overcome that the right-angle type buckle is difficult to dismounting in the existing technology, and defective such as demoulding difficulty.Meanwhile, in the assembly process of casing, the tilting bayonet unit of arranging through whole employing compactnesses; Two kinds of set-up modes that perhaps adopt the tilting bayonet unit to combine with the right-angle type buckle; The neutral position that can guarantee complete machine can be because card cannot fasten that the relative position that causes between the appearance component changes the defectives such as warpage that produce, thereby realized assembly relation good between appearance component and the bayonet unit, simple in structure; Be easy to realize having extensive applicability.

Embodiment

Below, through exemplary mode of execution the utility model is specifically described.Yet should be appreciated that under the situation that is not having further narration element, structure and characteristic in mode of execution also can be attached in other mode of execution valuably.

Referring to Fig. 3 and Fig. 4, a kind of easy-to-dismount bayonet unit 10 that it shows according to the utility model can be used for cooperating the structural member with snap-fitted relation.

Specifically, bayonet unit 10 comprises: buckle matrix 11 is fixedly connected on first structural member; And the buckle head 12 that protrudes from the buckle matrix.As shown in Figure 3, the buckle head 12 of the utility model is arranged on a side of buckle matrix 11, and the buckle head has the buckle face of two inclinations.Specifically, wherein buckle head 12 also has: the first buckle face 121 is arranged on the side that the buckle head leaves the buckle matrix farthest; The second buckle face 122 and the 3rd buckle face 123; Two ends from the first buckle face 121 extend out respectively; A side that is enclosed in buckle matrix 11 with the first buckle face 121 forms buckle head 12, and wherein the 3rd buckle face 123 is provided with the longitudinal axis M of buckle matrix 11 with tilting.

Be preferably, the 3rd buckle face 123 extends towards the direction away from the second buckle face 122, and the longitudinal axis M of the elongation line of the 3rd buckle face 123 and buckle matrix 11 in obtuse angle.Also promptly, the first buckle face 121, the second buckle face 122, the 3rd buckle face 123 have been formed the shape that roughly is isosceles trapezoid, and the first buckle face 121 is trapezoidal end face, and the second buckle face 122 and the 3rd buckle face 123 are trapezoidal two waists.

This bayonet unit also comprises the draw-in groove 30 that matches with buckle head 12; Be arranged on second structural member that first construct cooperates on; As shown in Figure 4; The buckle head 12 that protrusion is arranged on the buckle matrix 11 stretches in the draw-in groove 30, and the lower end surface 301 of draw-in groove is parallel to keep the engagement of the 3rd buckle face 123 and lower end surface 301 with the 3rd buckle face 123 of buckle head 12.

As shown in Figure 5, the bayonet unit 10 of the utility model can be arranged in the housing of handheld portable electronic product, for example on the plastic front 15 or handset shell of panel computer, and has multiple assembling form.

Specifically, according to first kind of assembling form, on a side of structural member, all be set to the tilting bayonet unit 10 of the utility model.This assembling form is applicable to that the overall dimensions of product is less, for example generally is not more than 150mm, or in the inside of product, especially is equipped with the situation such as space of arranging abundant buckle in the structural member interposition.

According to second kind of assembling form, be set to traditional right-angle type buckle form in the vicinity, neutral position of a side of structural member, other positions are provided with the bayonet unit 10 of tilting.This assembling form is applicable to that one side of product is longer, and for example greater than 200mm, or the neutral position does not have the situation that redundant space is arranged more buckle.

According to the utility model, through adopting the bayonet unit 10 of tilting, overcome that the right-angle type bayonet unit is difficult to dismounting in the existing technology, and defective such as demoulding difficulty.Meanwhile, in the assembly process of casing, through the bayonet unit 10 of whole employing tiltings; Two kinds of set-up modes that perhaps adopt the bayonet unit 10 of tilting to combine with right-

angle type buckle

20a, 20b; The neutral position that can guarantee complete machine can the defectives such as warpage that produce realized assembly relation good between appearance component and the bayonet unit because card cannot fasten that the relative position that causes between the appearance component changes, and are simple in structure; Be easy to realize having extensive applicability.
