These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-8The present embodiment provides a glasses frame with a detachable pile head 3 structure, comprising a lens frame 1, a glasses leg 2 and a pile head 3. Two groups of pile heads 3 are provided and are respectively installed on both sides of the lens frame 1. The glasses leg 2 is hinged to the pile head 3. Among them, the pile head 3 includes a first clamping member 4 and a second clamping member 5. Mounting grooves 11 are provided on both sides of the lens frame 1 corresponding to each pile head 3. The mounting groove 11 is provided through the thickness direction of the lens frame 1, and includes a first notch 111 and a second notch 112 opposite to each other. The first clamping member 4 can be inserted into the mounting groove 11 from the first notch 111, and the second clamping member 5 can be inserted into the mounting groove 11 from the second notch 112 and engaged with the first clamping member 4. The first clamping member 4 and / or the second clamping member 5 have elastic deformation ability. The lens frame 1 is also provided with a disassembly port 12 connected to the mounting groove 11, and the disassembly port 12 is used for inserting an external tool to deform the first clamping member 4 and / or the second clamping member 5 to release the engagement between the two. The stud 3 further includes a limiting portion, which can keep the first clamping member 4 and the second clamping member 5 in a clamped state fixed relative to the mounting groove 11, that is, the stud 3 can be stably connected to the lens frame 1 without being subjected to external forces. In this embodiment, the first clamping member 4 and the second clamping member 5 both have a certain elastic deformation capacity, so that the two can be clamped with each other in the mounting groove 11, and can be deformed and released under the action of external forces.

[0028] Specifically, the first clamping member 4 includes a U-shaped clamping slot body 41, and protrusions 411 are provided on two inner side walls facing each other of the clamping slot body 41. The second clamping member 5 includes a clamping body 51 and undercuts 52, and the undercuts 52 are respectively connected to two opposite sides of the clamping body 51, and the end of the undercut 52 away from the clamping body 51 can approach or move away from the clamping body 51 under the action of external force, that is, the undercut 52 has a certain elastic deformation ability. Figure 7 , the undercut 52 can be inserted into the slot body 41 of the first clamping member 4 along with the clamping body 51, and after passing over the protrusion 411 in the slot body 41, it forms a buckle connection with the protrusion 411, thereby realizing the clamping cooperation between the first clamping member 4 and the second clamping member 5. In this embodiment, the first clamping member 4 and the second clamping member 5 can both be made of high-strength plastic injection molding or alloy casting to ensure the clamping stability of the stump 3. Similarly, the lens frame 1 and the temple 2 can also be made of high-strength plastic injection molding or alloy casting.

[0029] Furthermore, when the first clamping member 4 and the second clamping member 5 are in a state of being mutually clamped, there is a gap between the middle position of at least one of the undercuts 52 and the inner wall of the slot body 41, and the disassembly opening 12 is used for allowing an external tool to be inserted into the gap and driving the end of the undercut 52 away from the clamping body 51 to move toward the clamping body 51, so that the undercut 52 and the protrusion 411 are released from the clamping connection. The middle position of at least one of the undercuts 52 is arc-shaped and concave, and the disassembly opening 12 corresponds to the concave position of the undercut 52. The concave portion of the middle position of the undercut 52 can increase the gap between the middle position of the undercut 52 and the inner wall of the slot body 41, and an external tool can be inserted from the outside of the lens frame 1 through the disassembly opening 12 into the concave portion of the undercut 52, thereby squeezing the undercut 52 toward the clamping body 51, so that the undercut 52 and the protrusion 411 are released from the clamping connection. In this embodiment, Figure 5 and 7 , only the undercut 52 far from the center of the lens frame 1 has an arc-shaped concave. In this way, on the lens frame 1, a disassembly opening 12 is corresponding to a pile head 3. A rod-shaped tool with an inclined surface at the end is inserted from the disassembly opening 12 into the installation groove 11, and the inclined surface is used to support the edge of the undercut 52, so that the undercut 52 is deformed as the rod-shaped tool goes deeper and releases the buckle connection with the corresponding protrusion 411. When the undercut 52 on one side is released, the undercut 52 on the other side can also be released accordingly, and the first clamping member 4 and the second clamping member 5 can be separated and disassembled. In addition, in this embodiment, the disassembly opening 12 is connected to the installation groove 11 in the shape of a circular hole, and the disassembly opening 12 is opened from bottom to top, so that the disassembly opening 12 is not easy to be seen when the glasses frame is normally worn, so that the appearance of the lens frame 1 is kept neat and beautiful.

[0030] A convex edge 412 is integrally connected to the side of the slot body 41 away from the slot, and the convex edge 412 can abut against the edge of the first slot 111 to limit the depth of the slot body 41 inserted into the installation slot 11. A tightening piece 511 is provided on the side of the clamping body 51 away from the undercut 52, and the tightening piece 511 can abut against the edge of the slot to limit the depth of the clamping body 51 inserted into the installation slot 11. The convex edge 412 and the tightening piece 511 together form the limiting portion, and through the cooperation between the convex edge 412 and the first slot 111, and the cooperation between the tightening piece 511 and the second slot 112, after the first clamping member 4 and the second clamping member 5 are completed, the forward and backward movement of the two along the plugging direction is limited, that is, the position of the pile head 3 and the installation slot 11 can be kept relatively fixed. In other embodiments, the limiting part may also be an additional plug-in component, a hole vertically connected to the installation groove 11 is opened on the lens frame 1, and after the first clamping component 4 and the second clamping component 5 are mutually clamped, the plug-in component is inserted into the hole and can limit the movement of the first clamping component 4 or the second clamping component 5 along the insertion direction. However, this method will make the entire pile head 3 structure more complicated, and the installation and disassembly will be more cumbersome.

[0031] In addition, the abutting piece 511 has a certain elastic deformation ability. The abutting piece 511 is arranged on both sides of the clamping body 51 and extends obliquely toward the undercut 52. When the clamping body 51 and the undercut 52 are inserted into the slot body 41, and the undercut 52 and the protrusion 411 are clamped, the abutting piece 511 can abut against the edge of the second notch 112 and store energy, thereby keeping the undercut 52 and the protrusion 411 in a fastened state, preventing the first clamping member 4 and the second clamping member 5 from loosening. When the undercut 52 and the protrusion 411 are unclamped by an external tool, the abutting pieces 511 on both sides of the clamping body 51 release energy so that the clamping body 51 can move away from the slot body 41, so that the first clamping member 4 and the second clamping member 5 can be more easily disassembled.

[0032] In order to make the pile head 3 and the lens frame 1 more beautiful and neat after installation, the first notch 111 and the second notch 112 of the installation groove 11 are both stepped notch structures so that the outer surfaces of the slot body 41 and the abutting piece 511 do not protrude from the outer surface of the lens frame 1.

[0033] The first clamping member 4 further includes a connecting body 42, one end of which is connected to the convex edge 412 of the clamping slot body 41, and the other end is hinged to the eyeglass leg 2. Correspondingly, the lens frame 1 extends an embedding groove 13 on the side of the first notch 111 of the mounting slot 11, so that the connecting body 42 is partially embedded in the embedding groove 13 without protruding from the outer surface of the lens frame 1. At the same time, the connecting body 42 is partially matched with the embedding groove 13, which can also further improve the installation stability of the first clamping member 4 and the lens frame 1.

[0034] The second clamping member 5 also includes a force-applying portion 53, which is integrally connected to one end of the clamping body 51 away from the undercut 52, and the abutting piece 511 is arranged between the undercut 52 and the force-applying portion 53. During installation, the force-applying portion 53 is pressed, and the entire second clamping member 5 is inserted into the installation groove 11 to engage with the first clamping member 4, and the force-applying portion 53 can be completely sunk into the second notch 112 without protruding from the outer surface of the lens frame 1. When the abutting piece 511 releases energy, the force-applying portion 53 can partially protrude from the outer surface of the lens frame 1 as the clamping body 51 moves away from the installation groove 11, so that the force-applying portion 53 can be held by hand to remove the entire second clamping member 5, making disassembly more convenient.

[0035] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
