Description

Technical Field

[0001] This utility model relates to a sleeve-type mirror arm connection structure, belonging to the technical field of ice-making appliances. Background Technology

[0002] The main body of an eyeglass frame consists of the frame, bridge, and temples. The temples are connected to the frame via posts. Current technology generally uses standard hinges or concealed hinges to connect the temples and posts. These types of eyeglasses have a large number of parts and are difficult to install. Another type of eyeglasses uses clips to connect the temples to the posts, which is simple and easy to install, but the connection between the temples and posts may loosen after prolonged use. There are also integrated hinge structures that rely on the elasticity of the temples and posts to open and close the temples; however, if the temples of this type are damaged, the entire frame must be replaced, meaning the temples cannot be replaced. Utility Model Content

[0003] The purpose of this invention is to solve the problems of numerous parts and difficult installation in existing hinge-type telescope arm connection structures, easy loosening at the connection points of snap-on telescope arm connection structures, and the inability to replace and repair integrated hinge structures. This invention provides a sleeve-type telescope arm connection structure.

[0004] This utility model provides a sleeve-type telescope arm connection structure. The telescope arm is connected to the head of the lens frame via the connection structure. The connection structure includes an outer sleeve and an inner sleeve. The outer sleeve is connected to the telescope arm, and the inner sleeve is connected to the head. The outer sleeve is rotatably mounted on the inner sleeve, and at least a portion of the outer sleeve is fitted onto the inner sleeve. The inner diameter of the outer sleeve is not less than the outer diameter of the inner sleeve. The head has a use position perpendicular to the lens frame and a disassembly position parallel to the lens frame. When the head is in the use position, the outer sleeve cannot detach from the inner sleeve; when the head is in the disassembly position, the outer sleeve can be fitted onto the inner sleeve.

[0005] In this design, the temple has an unfolded position for wearing and a folded position for storage. When the socket is in the use position, the outer sleeve will not come out of the inner sleeve when the temple is in the unfolded, folded, or switching between the unfolded and folded positions. Furthermore, when the socket is in the disassembly / removal position, the temple is placed parallel to the frame, at which point the outer sleeve can come out of / into the inner sleeve.

[0006] Preferably, the cylindrical surface of the outer sleeve has a gap along the vertical direction, the gap is located near the root of the telescope arm, and the width of the gap is greater than the thickness of the pile head. The cylindrical surface of the outer sleeve has a clearance groove. The inner sleeve is connected to the pile head via a connecting plate. The connecting plate and the pile head form two notches, which are symmetrically arranged along the vertical direction of the connecting plate. The clearance groove corresponds to the connecting plate, and its width is greater than the height of the connecting plate. During installation, first, the pile head is in the disassembly / removal position. Then, the telescope arm and frame are placed in a parallel position. At this point, the gap aligns with the pile head, allowing the outer sleeve to enter the inner sleeve, thus completing the telescope arm installation. After installation, the pile head is bent to the usage position. At this point, no matter how the telescope arm is rotated, the gap and the pile head will not overlap, meaning the telescope arm cannot detach from the pile head.

[0007] Preferably, the connecting plate is in the form of a thin sheet with a rectangular longitudinal section.

[0008] Preferably, the height of the outer sleeve is the same as the height of the inner sleeve.

[0009] Preferably, the outer sleeve and the inner sleeve are clearance-fitted or transition-fitted.

[0010] Preferably, the head and temple are made of elastic steel. Elastic steel has good wear resistance, flexibility and deformation resistance, and is also lightweight. Using steel to manufacture the head and temple ensures that the glasses are sturdy and durable while remaining lightweight overall.

[0011] Preferably, the pile head, connecting plate, and inner sleeve are integrally formed.

[0012] Preferably, the outer sleeve head is integrally formed with the mirror arm.

[0013] Preferably, the temple is provided with a serrated portion for attaching the temple sleeve. By providing the serrated portion, the bonding strength between the temple sleeve and the temple can be improved.

[0014] The beneficial effects of this utility model are:

[0015] 1. The connection structure between the telescope arm and the pile head has been reduced, balancing installation convenience and connection strength.

[0016] 2. Easy to install and maintain; damaged arm can be replaced separately.

[0017] 3. The structure is simple and easy to process. The outer sleeve and the inner sleeve can be processed by stamping and bending.

[0018] 4. The glasses have good overall integrity, and the gap between the temples and the headpieces is small when the temples are in the extended position. Attached Figure Description

[0025] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, this utility model provides a sleeve-type telescope arm connection structure. The telescope arm 1 is connected to the post head 2 of the lens frame 9 through the connection structure. The connection structure includes an outer sleeve 3 and an inner sleeve 4. The outer sleeve 3 is connected to the telescope arm 1, and the inner sleeve 4 is connected to the post head 2. The outer sleeve 3 is rotatably mounted on the inner sleeve 4, with at least a portion of the outer sleeve 3 fitted onto the inner sleeve 4. The inner diameter of the outer sleeve 3 is not less than the outer diameter of the inner sleeve 4. The post head 2 has a use position perpendicular to the lens frame 9 and a disassembly position parallel to the lens frame 9. When the post head 2 is in the use position, the outer sleeve 3 cannot detach from the inner sleeve 4; when the post head 2 is in the disassembly position... The outer sleeve 3 can be fitted onto the inner sleeve 4. The connecting plate 8 is thin and has a rectangular longitudinal section. The cylindrical surface of the outer sleeve 3 has a gap 5 along the vertical direction. The gap 5 is located near the root of the mirror arm 1. The width of the gap 5 is greater than the thickness of the pile head 2. The cylindrical surface of the outer sleeve 3 has a relief groove 6. The inner sleeve 4 is connected to the pile head 2 through the connecting plate 8. The connecting plate 8 and the pile head 2 form two notches 7. The two notches 7 are symmetrically arranged along the vertical direction of the connecting plate 8. The relief groove 6 corresponds to the connecting plate 8. The width of the relief groove 6 is greater than the height of the connecting plate 8. The height of the outer sleeve 3 is the same as the height of the inner sleeve 4.

[0027] In this design, the temple 1 has an unfolded position for wearing and a folded position for storage. When the post 2 is in the use position, the outer sleeve 3 will not disengage from the inner sleeve 4 when the temple 1 is in the unfolded, folded, or switching between the unfolded and folded post 2 positions. Furthermore, when the post 2 is in the disassembly / removal position, the temple 1 is placed parallel to the frame 9, at which point the outer sleeve 3 can disengage / enter the inner sleeve 4. During installation, first, the post 2 is placed in the disassembly / removal position, then the temple 1 is placed parallel to the frame 9. At this point, the gap 5 is aligned with the post 2, allowing the outer sleeve 3 to enter the inner sleeve 4, thus completing the installation of the temple 1. After installation, the post 2 is bent to the use position. At this point, no matter how the temple 1 is rotated, the gap 5 and the post 2 will not overlap, meaning the temple 1 cannot detach from the post 2. Furthermore, the connecting plate 8 is located within the clearance groove 6. The connecting plate 8 is thin and has a rectangular cross-section, which makes it easy for the outer sleeve 3 to fit into the inner sleeve 4; the width of the clearance groove 6 is greater than the height of the connecting plate 8, so as to prevent the connecting plate 8 from getting stuck between the clearance groove 6 when the lens arm 1 rotates.

[0028] It should be noted that the outer sleeve 3 can be inserted into the inner sleeve 4 by the assembly staff by hand or by using a press-fitting device. There are no restrictions here, and the choice can be made according to the actual production situation.

[0029] The outer sleeve 3 and the inner sleeve 4 are fitted with a clearance 5 or a transition fit. By setting the outer sleeve 3 and the inner sleeve 4 to fit with a clearance 5 or a transition fit, the outer sleeve 3 can rotate relative to the inner sleeve 4, that is, the arm 1 can switch between the unfolded position, the folded position, and the unfolded position and the folded position.

[0030] The headpiece 2 and the temple 1 are made of flexible steel. Flexible steel has good wear resistance, flexibility and resistance to deformation, and is also lightweight. Using steel to manufacture the headpiece 2 and the temple 1 ensures that the glasses are sturdy and durable while remaining lightweight overall.

[0031] The head 2, connecting plate 8, and inner sleeve 4 are integrally formed. In actual production, the frame 9 can be processed by stamping and bending; the outer sleeve 3 and head 2 are integrally formed with the temple 1. In actual production, the temple 1 can be processed by stamping and bending; that is, the overall processing of the eyeglass frame 11 is relatively simple.

[0032] like Figure 4 As shown, the temple 1 is provided with a serrated portion 10 for hanging the temple sleeve of the temple 1. By providing the serrated portion 10, the bonding strength between the temple sleeve of the temple 1 and the temple 1 can be improved.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
