Description

Snap-in structure of spectacle frame and tripod

Technical field The utility model relates to glasses, in particular to structural parts of non-optical parts of glasses.

BACKGROUND OF THE INVENTION In the prior art, the conventional spectacle frames and tripods mostly use screws as connecting members for connection and locking. When using screws to assemble, tools such as screwdrivers must be used, which consumes manpower and time, and increases the cost of production and assembly. Moreover, after wearing glasses for a period of time, the screws will rust or loosen, which often troubles consumers. Therefore, the industry has also developed some screwless connection structures between spectacle frames and tripods, but these still have complex structures, cumbersome assembly and other deficiencies, which need to be improved.

The content of the utility model The technical problem to be solved by this utility model is to avoid the shortcomings of the above-mentioned prior art, and further improve the prior art to design a spectacle frame with a simple structure, easy assembly, no screws and a firm connection. The clamping structure of the tripod.

The technical scheme that the utility model proposes for solving the technical problem is:

Design and manufacture a clamping structure of a spectacle frame and a tripod, including a spectacle frame and a bipod; two card seats are respectively arranged on the left and right sides of the frame, and the front ends of the two card seats are respectively extended with clamping blocks; the tripod The connecting end of the connecting piece is a three-prong piece; there is a connecting piece between the frame and the tripod, and the connecting piece is in the shape of "I", and the upper and lower ends of the connecting piece are provided with card slots that match the clamping blocks. The middle section of the connector is a cylinder; the middle fork of the tripod is formed with an arc-shaped hook, and the arc-shaped hook is set on the cylinder of the connector, and the upper and lower forks of the tripod are flat At the upper and lower ends of the connector.

The card block and the card seat are bent back and forth in a wave shape, and the front ends of the card slots at the upper and lower ends of the connector are provided with a bayonet. .

Compared with the prior art, the beneficial effects of the clamping structure of the spectacle frame and the tripod of the present invention are as follows: 1. With the clamping structure of the present utility model, the connection between the frame and the tripod does not need to use screws, and the structure is simple. The assembly is convenient and the connection is firm; 2. The back and forth bending between the card block and the card holder is wavy, and the matching design of the bayonet improves the convenience of assembly and the firmness of the connection. the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

Referring to FIG. 1 to FIG. 7 , the glasses 1 adopting the clamping structure of the present invention include: a mirror frame 10 , two connecting parts 20 and a bipod 30 .

Wherein, the left and right sides of the picture frame 10 are respectively provided with two decks: an upper deck 11 and a lower deck 12; Between the upper card base 11 and the upper card block 111, between the lower card base 12 and the lower card block 121, all bend back and forth in a wavy shape with good elasticity. The wavy parts are shown as 112 and 122 in FIG.

The connector 20 is in the shape of an "I", and its upper and lower ends are provided with two card slots matching the upper block 111 and the lower block 121: the upper card slot 21 and the lower card slot 22 , the middle section of the connector is a cylinder 23; the front ends of the upper card slot 21 and the lower card slot 22 are respectively provided with an upper card notch 211 and a lower card notch 221, and the upper card block 111 and the lower card block 121 are respectively inserted and passed through the upper Behind the card slot 21 and the lower card slot 22, the wavy parts 112, 122 of the card holders 11, 12 are respectively accommodated in the card slots 21, 22 of the connector 20, and the upper card block 111 is locked and positioned by the upper card port 211, The lower block 121 is locked and positioned by the lower bayonet 221 .

The connecting end of the tripod 30 is a trident: an upper fork 31, a middle fork 32 and a lower fork 33, the middle fork 32 is formed with a very elastic arc hook 321, and the arc hook 321 is nested On the cylindrical body 23 of the connecting piece 20 , the upper fork piece 31 and the lower fork piece 32 are flatly attached to the upper and lower ends of the connecting piece 20 . In this way, the glasses 1 can be snapped into shape quickly and firmly (as shown in FIG. 1 ).

If the glasses 1 do not wear the folded tripod 30, as shown in Figure 5, the middle fork 32 of the tripod 30 takes the cylinder 23 of the connector 20 as the center, bends inwards at 90 degrees, and the two ends of the connector 20 are respectively The upper fork 31 and the lower fork 33 of the tripod 30 are pressed against each other, so that the glasses 1 are in a folded state.

When desiring to return the glasses 1 to the normal wearing and opening state, the middle fork 32 of the tripod 30 is also centered on the cylinder 23 of the connector 20, and the tripod 30 is pushed outward, and the elastic force of the trident can instantly move the foot. The rack 20 springs back to the state shown in FIG. 1 .

The above content is a further detailed description of the utility model in combination with specific preferred technical solutions, and it cannot be determined that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
