SPECTACLES WITH REPLACEABLE PINS

Abstract

Disclosed are spectacles with replaceable pins, and belongs to the technical field of spectacles. The spectacles with the replaceable pins may include a spectacle frame and the pins, an edge of the spectacle frame being pivoted with a bolt, the bolt being inserted into an inserting hole of the pin, an elastic piece pushing a stopping block to enter into an opening on a side of the pin, and the spectacle frame being connected with the pins in a buckling manner. When a pressure is applied to the stopping block, the stopping block withdraws from the opening on the side of the pin when elastic force of the elastic piece is overcome and retracts into the accommodation cavity, in this way the buckling connection of the spectacle frame with the pins is removed, the pins and the spectacle frame are demountable, and it is convenient to replace the pins.

Embodiment

[0032] As shown in FIG. 1-FIG. 3, spectacles with replaceable pins may include:

[0033] a spectacle frame 1, and

[0034] two pins 2.

[0035] Two opposite edges of the spectacle frame 1 are pivoted with a bolt 3, respectively.

[0036] An inserting hole 4 fitting the bolt 3 is formed on one end of the pin 2 in a concave manner.

[0037] A side of the pin 2 is provided with an opening 5 communicating with the inserting hole 4.

[0038] The bolt 3 is provided with an accommodation cavity 6 therein, and a stopping block 7 is accommodated inside the accommodation cavity 6. An elastic piece 8 is arranged inside the accommodation cavity 6 as well, and the elastic piece 8 may push the stopping block 7 to enter into the opening 5 on the side of the pin 2.

[0039] When connection of the spectacle frame 1 with the pins 2 is realized, the bolt 3 on the edge of the spectacle frame 1 is inserted into the inserting hole 4 of the pin 2, the elastic piece 8 pushes the stopping block 7 to enter into the opening 5 on the side of the pin 2, and the spectacle frame 1 is connected with the pin 2 in a buckling manner. When the connection of the spectacle frame 1 with the pins 2 needs to be removed, a pressure is applied to the stopping block 7, and the stopping block 7 withdraws from the opening 5 on the side of the pin 2 when elastic force of the elastic piece 8 is overcome and retracts into the accommodation cavity 6, in this way the buckling connection of the spectacle frame 1 with the pins 2 is removed.

[0040] In the embodiment, the accommodation cavity 6 is a square blind hole, the stopping block 7 is a square block fitting the accommodation cavity 6, an inner wall of the accommodation cavity 6 guides the stopping block 7 when the stopping block 7 is pushed by the elastic piece 8 in the accommodation cavity 6, and the stopping block 7 may be accurately inserted into the opening 5 on the side of the pin 2.

[0041] As shown in FIG. 1 and FIG. 2, in the embodiment, the elastic piece 8 is a compression spring, one end of the compression spring is placed in abutment with a bottom of the accommodation cavity 6, and another end of the compression spring is placed in abutment with a bottom of the stopping block 7. More specifically, in the embodiment, a counter bore 9 (as shown in FIG. 1) is arranged on a top end surface of the stopping block 7, a screw 14 goes through the counter bore 9 and the compression spring in sequence until it is screwed into a screw hole arranged on the bottom of the accommodation cavity 6, and the screw 14 locks the stopping block 7 and prevents it from departing from the accommodation cavity 6. Specifically, in the embodiment, there are two elastic pieces 8, and the two elastic pieces 8 are arranged on two ends of the stopping block 7, respectively. In other embodiments, there is one elastic piece 8, a round blind hole 15 (as shown in FIG. 4) is arranged in the middle of a bottom end surface of the stopping block 7. One end of the elastic piece 8 is placed in abutment with the bottom of the accommodation cavity 6, and another end of the elastic piece 8 is placed in abutment with a bottom of the round blind hole 15.

[0042] As shown in FIG. 1, in the embodiment, the bolt 3 is provided with a round angle 10 facilitating insertion of the bolt 3 into the inserting hole 4 of the pin 2, in this way convenience of assembling and disassembling the pins 2 and the spectacle frame 1 is further improved.

[0043] As shown in FIG. 1-FIG. 2, in the embodiment, the edge of the spectacle frame 1 is provided with a first limitation gap, and an end of the bolt 3 is provided with a first limitation block 11 fitting the first limitation gap. The first limitation block 11 of the bolt 3 may be placed in abutment with the first limitation gap on the edge of the spectacle frame 1 when the bolt 3 is opened, in this way a maximum opening angle of the bolt 3 is 90°. As shown in FIG. 2-FIG. 3, in the embodiment, the edge of the spectacle frame 1 is further provided with a second limitation gap 12, and the end of the pin 2 is provided with a second limitation block 13 fitting the second limitation gap 12. The second limitation block 13 of the pin 2 may be placed in abutment with the second limitation gap 12 on the edge of the spectacle frame 1 when the pin 2 is opened, in this way a maximum opening angle of the pin 2 is 90°.

[0044] The abovementioned embodiment presents several embodiments of the disclosure only, and its description is relatively specific and detailed, but the specific and detailed description shall not be understood as limits to the scope of patent of the disclosure. It is to be pointed out that those of ordinary skill in the art can make various variations and improvements without departing from the concept of the present disclosure as well, and these variations and improvements shall also fall within the scope of protection of the disclosure. Therefore, the attached claims shall prevail in terms of the scope of protection of the disclosure.
