Background technology

Two sides of Swimming mask all are provided with framework, and bracelet respectively is set on framework, and a safe headband is arranged on two bracelets.The bracelet of commonly using is a rotating structure, and bracelet is provided with a pin on framework, is the center with the pin, makes bracelet can limitedly do low-angle turning to, and can borrow the length of the structural adjustment headband of bracelet.

The main purpose of said structure makes headband can do the rotation of certain certain angle, makes bracelet be positioned at safe position; Next is that headband can be adjusted, and is arranged on the comfortable position of ear top, and the center of rotation of in fact known rotation bracelet makes headband be difficult to both reach and is positioned on the ear very near the position of ear, and can encircle smoothly again on user's head.Generally speaking, the rotation bracelet of commonly using can only be fixed on certain position, and therefore, headband can't be adjusted at the ideal position on user's head.Change speech, this kind rotates bracelet, or even fixed bracelet, and headband must bending or deflection, so that the headband position is in the ear top.

Desirable state should be with the pivoting point point of bracelet effectively away from user's ear, and must be position comfortable above ear around the headband of user's head.If improve to commonly use the structure that shaft tip is set on the buckle in, then shaft tip may must be arranged on the front end or eyeglass or face shield etc. of framework, and in fact, desirable center of rotation should be the anterior position at eyeglass.Therefore, traditional structure can't be reached this ideal.Again, desirable bracelet must be to make headband selectively be positioned at some positions, makes on the head that face shield is arranged at the user that headband can be safe, comfortable.

The utility model content

Main purpose of the present utility model is providing a kind of Swimming mask structure of novelty, and a pair of bracelet of structure can provide the user more comfortable headband.

Another purpose of the present utility model has a backbone point that the position is more preceding at bracelet that Swimming mask is provided and framework thereof.

Another purpose of the present utility model is providing Swimming mask to have the bracelet that can move along crank slot, in order to adjust the position of headband.

For achieving the above object, the technical solution of the utility model provides a kind of Swimming mask, comprise: an eyeglass is arranged on the framework, one headband is arranged on the swimming goggle, and a pair of bracelet is arranged on the framework, and headband is arranged on the bracelet, has long groove on the framework, described bracelet contacts with groove is moving, makes above-mentioned bracelet can select suitable position, so that headband can be selected the suitable position of position on user's head.

Wherein long groove has an arc, makes bracelet have the axial centre band.

Wherein the axial centre band has a backbone point.

Wherein bracelet has slide block, and slide block can move on alleged long groove.

Wherein bracelet has upper member and lower member, is provided with rotating shaft on lower member, and headband is moved thereon, has a stop section on upper member, borrows both cooperation that headband can be loosened or is put by lock.

Wherein upper member or lower member have mutual fastening structure.

Its middle frame has a plurality of recesses, has at least one projection on the buckle in, borrows projection optionally to be arranged on a certain recess, makes on the position that is arranged on framework that bracelet can be more stable.

The utility model Swimming mask has one can be made on the crank slot that bracelet slides on frame facet; And, the center position of bracelet (to call backbone point in the following text) more the place ahead in the position of the backbone point of the rotation bracelet of commonly using.This backbone point can be the position that exceeds face shield in crank slot the place ahead, and the position is in the place ahead of eyeglass.And the utility model structure, assembling be all very clear and definite, easily, and can provide headband to do effectively to adjust, so that headband can be selected suitable position on user's head, position.

The specific embodiment

As shown in Figure 1, known Swimming mask 10 has one (or three) eyeglass 11 device on the framework 12, on headband 13 device buckle in 14,12 of buckle in 14 and frameworks are provided with a center pin 15, and headband 13 is that the axle center can limitedly be rotated with bracelet 14 with this center pin 15; As shown in the figure, headband 13 has the ear first half some degree and the user to go to upper and lower or closed state.

As shown in Figure 2, the Fastener structure of the utility model novelty is in more headband can to adjust, more can makes it be in comfortable position.The utility model face shield 20 comprises eyeglass 21, framework 22, headband 23 and bracelet 24.Shown in Fig. 2,3,4, bracelet 24 is arranged on the side 25 of framework 22, be make bracelet 24 slide block 26 positions on the button groove 27 of arc, arcuate furrow 27 has backbone point 28.

Shown in Fig. 5,6, bracelet is by two member combinations basically, comprises upper member 29 and lower member 30, two members are in conjunction with also installing in the groove 31 of frame facet 25, a plurality of recesses 32 are set, provide the projection 33 of lower member 30 to snap in, bracelet is not moved easily.

Shown in Fig. 7 to 10, be a kind of Fastener structure: upper member 29 is provided with headband and gives as security plate 34, gives as security the top that plate 34 is arranged at moveable body 35, and the below of body 35 is provided with the slide block 26 of a projection, and slide block 26 back sides are provided with recess 36.The shelves that giving as security plate 34 provides the button portion 37 of finger that controlled moving headband 23 advance and retreat usefulness are set end portion 38.

Lower member 30 has a body 41, and a pair of wing frame 42 is set on the body 41, provides an axle 43 on 42 on two wing framves; Body 41 downsides are provided with a button piece 44, at the reverse side place of button piece 44 projection 45 are set.
